From the prior art Mehrfachkoaxialverbinder are known which are suitable for the simultaneous connection of several connectors with a coaxial cable guide. For example, the Applicant is aware of a 16-way multi-coax connector with the product name Mc16. This has a distance of about 4mm between the individual connectors and is suitable for frequencies up to 40GHz. Also known is a single connector called MMPX, which is suitable for frequencies up to 65GHz, but has a relatively high insertion force. From other manufacturers, various products are known, which are offered for the transmission of signals at high frequencies:

• Gore UHD (coaxial connector, 6 - 9GHz, 19db. <78 channels per square inch, interface stamping / bending technology, housing KS injection molding)
• Tyco Nanonics Multi Coaxial Connector (20GHz, 2.54mm center-center pitch, metal case, similar to sub-D, max 1x9)
• Tensolite HDRFi Multi Coaxial Connector (40GHz, 3.3mm center-center pitch, metal case, similar to sub-D or round, planar contact, about 40 channels per square inch in 11-sub-D)
• Synergetix "Spring Contact Fields" (up to 20GHz, approx. 1.95mm center-center pitch with best arrangement for high-frequency contacts, open field, freely configurable, approx. 170 channels per square inch)

The FCI is well aware of a connector system called the AirMax VS High Speed Connector System . The connectors are made up of individual layers and have no shielding. They are therefore only limited for the transmission of high frequencies.

EP1021852 (EP'852) was deposited on behalf of Tyco Electronics and concerns a coaxial RF connector for transmitting high frequency electromagnetic waves. The connector has a housing with at least one inner contact and with an outer contact arranged coaxially around the inner contact. EP'852 is based on the object to show an RF coaxial connector, which is simple and inexpensive to produce with sufficient outer conductor surface thickness. In addition to be found in the RF coaxial connector also a secure electrical connection with an outer conductor of a Koaxialgegensteckers, so the outer conductor function to be ensured. This object is to be achieved in that the housing is formed as an injection molded plastic, and that the housing has a made of plastic and around the inner contact coaxially disposed wall portion, wherein at least the inner contact facing inner wall is provided with a sufficiently thick metallization ,

From electronics 7./8.4.82, page 146 is already known to provide a multi-pole connectors plastic housing and to provide this shielding reasons with a surface metallization. However, these multipolar connectors are not about coaxial connectors, where there is always a contact pair of internal contact / coaxial external contact. Rather, these known connectors on a plurality of contact pins, which are surrounded by a common housing boundary, which is metallized surface. To realize an outer conductor function by metallizing a hollow cylindrical inner wall of the housing thus plays no role there.

EP0582960 (EP'960) was filed in the name of Siemens AG and relates to a coaxial RF connector with several, at a certain pitch on a base, such as a printed circuit board, arranged coaxial connectors and corresponding arranged on a base coaxial mating connectors. EP'960 is based on the object of providing a small pitch of, for example, 5 mm suitable, ie mechanically and electrically adapted RF coaxial connector in a simplified connection technology. According to the description of EP'960, the object is achieved by an RF coaxial connector having the following features: a) the coaxial connectors are fastened with press-fit contacts to their base, b) the mating connectors are in a monoblock corresponding in number to the number of coaxial connectors c) the monoblock is made of conductive material and forms the outer conductor for all coaxial mating connectors integrated in it; d) the inner conductors of the coaxial mating connectors and their connections for the underlay are each insulated in bores of the monoblock, e) the connections of the inner conductors the coaxial mating connector and the outer conductor terminals of the monoblock are formed as press-fit.

US4571014 AT & T was deposited in 1986 and shows a connector with a variety of contacts and a modular, relatively complicated structure. The connector is assembled from a variety of different parts and should be suitable for use with printed circuit boards. The connector has no coaxial construction on.

The prior art connectors are not suitable for use in a high density array in the range of 100 channels per square inch as e.g. in test arrangements for testing chips or microprocessors are used, where a large number of connector sites must be connected simultaneously in a small space and high frequencies must be transmitted. One reason for this is that due to the design no arrangement with appropriate packing density is possible. Also can not be guaranteed that all connectors are securely connected to each other.

US5190472 by WL Gore & Associates, Inc., filed in 1992, shows a multi-coaxial connector that targets high channel density. Individual coaxial connectors are inserted in half in comb-like, half-round recesses arranged on two sides of a so-called Gruppiermoduls from the side. Since the recesses only half surround the connectors, the individual connectors are not held in the individual recesses and fall out of these. Only by the juxtaposition of several Gruppiermodulen the individual connectors are clamped and thus find support. Without stacking, grouping modules as such are not functional. The layered grouping modules, which are equipped with the individual connectors, are pressed rigidly into an outer frame from the rear and thus assembled to form a functional multiple coaxial connector. Although the described principle of a multiple coaxial connector theoretically allows multiple connectors with a comparatively high number of connectors, it has significant disadvantages. On the one hand, the assembly is extremely difficult. On the other hand, the individual, very filigree designed connectors are kept very rigid, which has a negative effect in the construction of connectors with a high number of channels due to the building up tolerance chains. Another disadvantage is the large number of very small and different components that are expensive to manufacture and therefore the corresponding Mehrfachkoaxialverbinder can be very expensive.

WO-A-02/05 6426 discloses a connector according to the preamble of claim 1.

An object of the invention is to show a multi-coaxial connector suitable for use in a high density array in the range of 100 channels or more per square inch and which does not have the disadvantages of the prior art.

This object is achieved by a Mehrfachkoxialverbinder according to the independent claim.

With increasing packing density (channels per area), the individual coaxial connectors and the housing parts holding them become smaller and smaller. This has the consequence that manufacturing tolerances are increasingly affecting and thus connectors with a high number of channels are very difficult to produce. Consequences of this can be high insertion forces, mechanical deformations or malfunctions. Another problem arises from the difficult logistics of the small parts.

The invention takes these circumstances into account, in that the typically resulting tolerance chain is intentionally interrupted by the construction according to the invention and the construction method. This is achieved in that a multiple coaxial connector according to the invention has a modular construction with a plurality of connector banks, wherein the individual connector banks as such generally constitute functional units. The connector banks typically include a plurality of individual coaxial connectors arranged in one or two rows. The individual coaxial connectors are attached for this purpose in recesses of a body and have a floating bearing to compensate for tolerances. The individual connector banks are operatively connected to one another in a defined measure, at least on the cable side, to form a larger unit. If necessary, the individual connector banks have centering means by means of which the individual connector banks are aligned and adjusted separately. alternative or in addition, the individual connectors can serve as a centering aid depending on the field of application.

An inventive connector according to claim 1 comprises one or more male and one or more male connector banks each having one or two rows (e.g., 1x8, and 2x8 respectively) of interconnectable individual (female and male) connectors of preferably coaxial construction. The housing of the connector banks (especially on the cable side) and the arrangement of the individual connectors in the connector banks enables a high packing density. It has been found that connector banks with more than two rows of single connectors, which can not be built in a manner according to the invention from the side, are very difficult to manufacture. The individual connector banks are floatingly connected to larger units. Floating connections can be effected by elastic elements or outer housing. Good results for a floating bearing are achieved by laterally arranged elastic connecting elements which operatively interconnect the individual connector banks.

In one embodiment, the individual connectors on the one connector side may be connected directly to a corresponding number of coaxial cables and then pressed or inserted into recesses of a housing located on one or two (opposite) sides of a body. If necessary, the recesses can be closed with lids.

On a remote side, connectors may be arranged in a corresponding number in a one- or multi-part housing and cooperate with a printed circuit board or also be attached to a corresponding number of coaxial cables. The case on the The opposite side may be made of a conductive material, eg metal or a plastic coated with a conductive layer, and take over the function of the shielding. The housing may be provided for mounting on a printed circuit board.

A multiple coaxial connector in accordance with the invention has a cable side (where the cables are connected) of modular construction which can accommodate various expandable configurations, e.g. 1x8, 2x8 or nx8 (n stands for any number), resp. nx2x8 allowed. It will be clear to those skilled in the art that one of 8 different number of connectors per row is possible, depending on the field of application. One advantage is that the connector, u. a. due to the improved accessibility, can be made easier and different embodiments can be assembled to a high degree of equal parts. The individual housing parts are floating, e.g. via laterally or interposed elastic connecting elements, e.g. be made of rubber or similar materials interconnected. As a result, certain tolerances when connecting with a counter element balanced, resp. the tolerance chains are interrupted.

For this purpose, the individual connectors are pressed on each side of the connector in one or more housings, which serve to hold the same - depending on the embodiment, rigid or floating - serve. The housings are preferably made of injection-molded plastic. The operative connection with the cables takes place by compression or soldering.

If necessary, the individual connectors have spring elements by means of which the insertion force with the counterpart is determined and any deviations are compensated to a defined extent. Depending on the embodiment, the spring elements are, for example, bellows-shaped or have a barrel-shaped configuration which, if necessary, in the longitudinal direction or slotted at a certain angle, such that the load level does not exceed a certain value.

A connector is typically suitable for bandwidths of 25GHz or higher for SMD mountable vertical PCB connectors. The special design allows for the first time densities of 100 channels or more per square inch. The distance between two individual connectors (center-center-pitch) is typically at most 2 mm. Another advantage is that the technology is suitable for the production of series and the connectors are inexpensive to produce. The goal is achieved by reducing to the essential elements of a coaxial interface printed circuit board (PCB) to cable connector.

The inventive concept allows u. a. microscopic dimensions. For cost-effective production, the metal parts are preferably designed so that they are for the production by means of stamped bending, resp. Thermoforming technology suitable, the housing is preferably designed so that it can be made of injection-molded plastic.

The alignment principle is based on the fact that the individual connector banks are centered individually and largely independently of one another via centering elements. The alignment principle is thus always finer via centering pins and outer conductors to the inner conductor. Nxl6 configuration is realized via loosely coupled 1x16 connectors, so that no tolerance chain is built up via more than 16 connectors.

One field of application for high channel density connectors in accordance with the invention is testing and measurements in the manufacture and development of high speed serial data communications components. Here, many high-speed serial channels (currently around 6 to 15 gigabits per second, Gbps) are transmitted in parallel. For a better quality Each channel is preferably differentially guided per direction. A "full duplex" connection requires four physical connections.

In metrology, the signals should be transmitted as smoothly as possible, so the connections are preferably guided coaxially. The signals are generated in integrated silicon circuits. For a high signal quality, therefore, the cable lengths on PCB should be kept as short as possible. Since the distance between the signal pads on the chip housing a few tenths of a millimeter, the shorter the cable length can be, the closer the coaxial connector can be mounted to the chip housing and thus the smaller and denser the entire compound. Embodiments such as e.g. the described "1x8" or the "2x8" variant with approx. 2mm center-center distance are particularly suitable for this purpose. Depending on requirements, 2 or 4 serial full-duplex channels can be routed.

Another field of application is the "Automated Test Equipment" market with the so-called "test heads" required there. Here, many serial connections are routed from a test head to a measurement station by a so-called "loadboard". A typical example is a current digital IC such as a processor, graphics chip, or similar devices that contain a variety of serial channels and currently typically achieve data rates up to 6 Gbps. In the future, data rates up to 15Gbps are expected. The number of channels can reach 100 or more per chip. This requires a high quality multi-channel connector with a corresponding number of channels. Due to the tight space conditions on the loadboard and the preferably short PCB connections, 100 channels per square inch are an advantage. This can be achieved with a connector according to the invention in a cost-effective manner.

Further potential applications are in general measurement technology, generally in high-speed digital data transmission or digital signal processing (eg in mobile radio base stations). Because of the flexibility and the easy to achieve However, the small size of the new connector can also be used to develop a family that leads to a new standard. The inventive design of the connector high-quality data transmission with a plurality of channels is possible.

The multi-coaxial connector includes a female and at least one cable-side male connector part. The cable-side connector part has at least one connector bank with a housing which has a base body. The main body has accessible from one or two opposite sides, comb-shaped recesses arranged, which serve for the lateral reception of individual connectors. The cable-side connector part has a plurality of laterally adjacent and operatively connected connector banks. The cable-side connector banks may be e.g. be elastically connected with each other via elastic connecting elements. The female connector part, e.g. is rigidly mounted on a board, may have a one-piece housing with parallel openings, which serve to accommodate individual connectors. The connectors can be pressed or snapped in the female connector part from the front or the back. If desired, the one-piece housing may have multiple rows of openings. To compensate for geometric deviations, the individual connectors can be mounted laterally floating at least in a housing. If necessary, the connector banks can have centering means by means of which the housings are centered when plugged together.

In the figures, like reference numerals are used for corresponding parts.

FIG. 1 shows a first embodiment of a multi-coaxial connector 1 in a perspective view obliquely from the front and bottom. FIG. 2 shows the same multiple connector 1 obliquely from the front and top and FIG. 3 shows the multi-connector in an open and partially sectioned view from above obliquely.

The Mehrfachkoxialverbinder 1 consists of a male and a female connector bank 2, 3, which are operatively connected by plugging together. Both parts 2, 3 have a plurality of male and female connectors 4, 5 which are coaxial here and which are located in a common upper first and second lower, one-part, outer housing 6, 7 are arranged. The male and female coaxial connectors 4, 5 are in the FIGS. 4 and 5 shown enlarged. In the figures, the male and female connector 4,5 and the connector bank 2, 3 are shown separated from each other (not operatively connected), so that the individual details are better visible. On the housing 6 of the male connector bank 2 guide pins 27 are arranged, which engage in the operative connection with the female connector bank 3 in designated centering openings 28 on the second housing 7 and the housing of the individual connector banks 2, 3 align each other. A connector bank 2, 3 of the illustrated embodiment each has 16 connectors coupled together so that no tolerance chain is built up over more than 16 connectors. In order for the coaxial connectors 4, 5 to align with one another during the connection, they are mounted floating on one side in one of the housings 6, 7 in the lateral direction.

How out FIG. 3 shows the outer housing 6 of the male connector bank 2 of the multi-coaxial connector 1 is designed in several parts. It has a base body 8 with comb-like recesses 9, which are suitable for receiving male connectors 4. The recesses 9 are arranged on two opposite sides of the main body 8 and have a parallel orientation to each other. They are two-row and with reference to the floor plan, here at an angle of 60 ° laterally offset from each other (other forms of arrangement are possible). The main body 8 can be easily equipped with connectors 4, 5 with high packing density due to its accessible from both sides configuration of the recesses 9. The recesses 9 can be designed such that the connector 4 can be snapped laterally into this.

On both sides of the main body 8, lids 10 are arranged, which close off the main body 8 against the outside and secure connectors 4, 5 inserted in the recesses 9 against falling out. In the embodiment shown, recesses 9 are on both C-shaped sides, so that they completely enclose the connector 4 in the assembled state.

Depending on the field of application, the cover 10 may be glued to the base body 8, screwed, welded or be releasably or permanently connected via snap connections. The connectors 4 are movably arranged in the recesses 9 in a defined dimension, such that they have a certain tolerance at least laterally. Depending on the field of application, the recesses 9 may also be U-shaped, so that the individual connectors 4 can be snapped into the latter from the side and no cover is required.

In contrast to the first housing part 6, the second housing part 7 of the embodiment shown is configured in one piece and provided for mounting on a circuit board (not shown in detail). The second housing part 6 has a plurality of parallel openings 11, which are suitable for receiving connectors 5. The female connectors 5 are pressed into the openings 11 for this purpose. In the embodiment shown, the screen is formed by the second housing part 7, which is designed to be conductive. If necessary, the second housings 7 may have more than two rows of connectors 5.

The housing parts 6, 7 are preferably made of plastic or metal and, if necessary, at least partially coated with a conductive material. The housings 6, 7 of the embodiment shown are designed such that they are suitable for the manufacture by injection molding of plastic or another material. Due to the multi-part construction undeformable undercuts can be avoided.

The connector banks 2, 3 have a two-row structure, which allows a compact arrangement of the individual connectors and thus a high density of channels per area, since the individual connectors can be placed very close to each other. Interconnects with more than two rows, especially on the cable side, they are considerably more difficult to install. Optimum utilization at a very high channel density per area is achieved, at least on the cable side, with single-row or single-side accessible double-row connector banks accessible from one side. If the connector is provided on one side for mounting on a printed circuit board or the like, more than two rows can also be provided on this side. If necessary, the base bodies 8 can be designed such that they serve as covers for an adjacently arranged base body.

Like from the FIGS. 3 to 5 As can be seen, the male connectors 4 are each attached directly to a coaxial cable 12. The construction of the connectors 4, 5 is relevant to the achievable packing density. For this reason, the connectors 4, 5 paid attention to high integration and a particularly compact design.

The male connector 4 have a sleeve-shaped electrically conductive outer part 13 which is barrel-shaped at its front end and provided with a plurality of longitudinally extending slots 14, so that a better spring action is achieved. At the rear end, the sleeve-shaped outer part 13 in the interior of a paragraph 15 which, as a stop for an outer shell, respectively. a screen 16 of the coaxial cable 12 is used. On the outside, the outer part 13 on a first thickening 17, which in the assembled state in the housing 6 (see. FIGS. 1 to 3 ), with a correspondingly formed groove 18 is engaged. The thickening 17 and the groove 18 are designed so that they secure the connector in the assembled state against accidental displacement in the axial direction. In a stamped bent part, the thickening 17 can be achieved with a constant wall thickness by a local widening.

The sleeve-shaped outer part 13 is attached to the outer jacket 16 of the coaxial cable 12. Depending on the application, different types of fastening are used. Good results are achieved by pressing, gluing or soldering. On an inner conductor 19 of the coaxial cable 12, a likewise sleeve-shaped first inner part 20 is attached, which is flared at the front end and provided with slots 21 so that the spring force does not exceed a defined level. To improve the contact, the sleeve-shaped inner part 20 has an inwardly projecting second thickening 22. The distance between the sleeve-shaped outer part 13 and the inner conductor 19 is given by an insulation 23 of the coaxial cable 12. In addition, if required, further spacer means, for example made of plastic or a non-conductive material, may be provided in the male connector 4 between the outer part 13 and the first inner part 20.

The female connector 5 consists in the embodiment shown of an insulating spacer sleeve 24 and a pin-shaped second inner part 25. The second inner part 25 is pressed into the spacer sleeve 24 and has anchoring elements 26 which prevent accidental displacement. The rear end is designed thickened and protrudes in the mounted state on the housing 7 (see. FIG. 3 ) and serves as a contact to a board (not shown).

As in FIG. 3 can be seen, the female connector parts 5 are pressed from behind into the opening 11 of the second housing 7 and are arranged in the assembled state in the interior thereof. In the embodiment shown, the female connectors do not have a screen. This is provided by the second housing 7, which is either made entirely of conductive material or coated at least in the region of the inner surface of the openings 11 with such. In the operatively connected state, the conductive outer parts 13 of the male connectors 5 make a conductive connection with the inner surfaces of the openings 11 (outer conductor). At the same time, the sleeve-shaped first inner parts 20 and the pin-shaped second inner part 26 are also operatively connected in this state and form an operative connection for transmitting high-frequency signals (inner conductor).

FIG. 6 shows an embodiment of a Mehrfachkoaxialverbinder array 30 in a perspective view. The connector 30 has a modular construction with a high number of channels per area. The male connector part 31 consists in the embodiment shown of individual parallel next to each other and laterally disposed elastic supports 32 floating operatively connected connector banks 2. Also, if necessary, the coaxial connector 4, 5 in a defined measure in the housings 6, 7 laterally floating be stored.

The housing of the female connector part 33 consists in the embodiment shown of several individual connector banks 3 as in the FIGS. 1 to 3 described. The connector banks 3 are mounted side by side on a board.

FIG. 7 shows a second embodiment of a Mehrfachkoaxial connector 1 in a perspective view obliquely from above. The structure essentially corresponds to that of the connector 1 according to the FIGS. 1 to 3 , For the description of the general operation, reference is therefore made to these figures. For ease of understanding, the first housing 6 is opened and the second housing 7 shown partially cut.

In contrast to the connector according to the FIGS. 1 to 3 the connector shown here is designed in a single row. The housing 6 of the male connector bank 2 is designed in two parts and consists of a base body 8, which has a plurality of juxtaposed recesses 9 for receiving cables 12 and with these male coaxial connectors 4 operatively connected. The connectors 4 have thickenings 17, which are arranged in the mounted state in grooves provided for this purpose 18 and prevent longitudinal displacement. A cover 10 which is also provided with a corresponding number of recesses 9, serves to close the housing 6 (shown schematically by a line s). In the rear region of the recesses 9, the main body 8 and the lid 10 constrictions 29, which is dimensioned so that the cables 12 are clamped controlled in the closed state in this area for the purpose of strain relief. The female connector bank 3 is also configured in a single row. The female connector 5 are also pressed in the embodiment shown from behind into the second housing 7.

FIG. 8 shows two male and two female connectors 4, 5 shown in a perspective view of each other. In the front connector pair 4, 5, a front portion is cut away from 90 °, so that the interior of the connector 4, 5 is more visible. The connectors 4, 5 corresponding to the connectors 4, 5 of the third embodiment of the multi-coaxial connector 1 according to FIG. 7 , but can also be used in principle in an embodiment shown in the preceding figures.

The male connector 4 have inside a first spacer sleeve 34 which is disposed between the sleeve-shaped outer part 13 and the first inner part 20 connected to the inner conductor 19 of the coaxial cable 12 and these spaced from each other. The spacer sleeve 34 is usually made of an insulating material and serves to hold the parts.

The female connector 5 has here (in contrast to the embodiment according to the FIGS. 4 and 5 ) An outer conductor 35, which is arranged opposite the second inner part 25 via a second spacer sleeve 36 spaced. The outer conductor 35 cooperates in the mated state with the sleeve-shaped outer part 13 of the counterpart 4, during which the first inner part 20 is conductively connected to the second inner part 25 in the inserted state.

Thus, the connection between the individual parts is made safe and to compensate for certain geometric variations in the longitudinal and transverse directions, both the outer conductor and the second inner part of a bellows 37, 38 on. In difference to the connectors 4, 5 according to the FIGS. 4 and 5 which interact laterally with one another, the connectors 4, 5 shown here cooperate via end contacts.
