Doppelstöckige LeiterplattensteckbuchseDouble-level PCB socket
Die Erfindung betrifft eine doppelstöckige Leiterplatten- steckbuchse nach dem Oberbegriff des Patentanspruchs 1.The invention relates to a double-level printed circuit board socket according to the preamble of patent claim 1.
Derartige Leiterplattensteckbuchsen sind insbesondere im Zu¬ sammenhang mit den von mehreren Firmen angestrebten standar- disierten USB (Universal Serial Bus)-Konzept bekannt geworden und von Interesse. Bei diesem neuen Bus-System geht es grund¬ sätzlich darum, die Anschlüsse von Peripheriegeräten an einen PC nicht mehr wie bisher über einzelne parallele Anschlüsse mit getrennten und oft unterschiedlichen Steckverbindersyste- men vorzunehmen, sondern die Peripheriegeräte an eine gemein¬ same Busleitung anzuschließen, die über eine standardisierte Steckbuchse am Gehäuse des PC unmittelbar mit einer Leiter¬ platte (motherboard) des PC verbunden ist. Das Steckgesicht dieser Leiterplattensteckbuch.se (receptacle) ist im wesentli- chen bereits festgelegt und weist vier in einer Ebene neben¬ einanderliegende streifenförmige Kontaktfedem auf, die beim Stecken des Kabelsteckerε (plug) mit den in diesem angeordne¬ ten vier nebeneinanderliegenden Kontaktschienen die elektri¬ sche Verbindung zwischen Kabel und Leiterplatte realisieren.Such circuit board sockets have become known and are of particular interest in connection with the standardized USB (Universal Serial Bus) concept sought by several companies. The basic principle of this new bus system is to no longer make the connections from peripheral devices to a PC, as was previously the case, via individual parallel connections with separate and often different connector systems, but to connect the peripheral devices to a common bus line, which is connected directly to a PC board (motherboard) of the PC via a standardized socket on the housing of the PC. The plug face of this printed circuit board socket (receptacle) is essentially already defined and has four strip-shaped contact springs lying next to one another in a plane, which, when the cable plug is plugged in with the four adjacent contact rails arranged in it, the electrical Realize the connection between the cable and the circuit board.
Die bekannten doppelstöckigen Leiterplattensteckverbinder mit zwei Stecköffnungen für insgesamt zwei Kabelstecker besitzen in jeder Stecköffnung vier Rasthaken (zwei oben und zwei un¬ ten) um die geforderten hohen Ziehkräfte gegen ein unbeab- sichtigtes Lösen des Kabelsteckers zu realisieren. Jeder die¬ ser Rasthaken klingt beim Steckvorgang in eine passende Aus¬ sparungen des Kabelsteckers ein. Die Integration aller Rast¬ haken in den kompletten Steckverbinderaufbau ist hinsichtlich der resultierenden mechanischen Festigkeit und der Montage- freundlichkeit problematisch. Der Erfindung liegt die Aufgabe zugrunde, einen verbesserten Leiterplattensteckverbinder der eingangs genannten Art zu schaffen.The known double-decker circuit board connectors with two plug openings for a total of two cable plugs have four latching hooks (two at the top and two at the bottom) in each plug opening in order to achieve the required high pulling forces against unintentional loosening of the cable plug. During the plugging process, each of these latching hooks sounds into a suitable recess in the cable plug. The integration of all locking hooks in the complete connector structure is problematic with regard to the resulting mechanical strength and ease of installation. The invention has for its object to provide an improved circuit board connector of the type mentioned.
Diese Aufgabe wird durch eine Leiterplattensteckbuchse mit den Merkmalen des Patentanspruchs 1 gelöst.This object is achieved by a printed circuit board socket with the features of claim 1.
Die Erfindung wird nachfolgend anhand eines Ausführungsbei¬ spiels im Zusammenhang mit Figuren näher erläutert.The invention is explained in more detail below on the basis of an exemplary embodiment in connection with figures.
FIG 1 zeigt eine perspektivische Ansicht der erfindungsgemä¬ ßen Leiterplattensteckbuchse,1 shows a perspective view of the circuit board socket according to the invention,
FIG 2 in gleicher Darstellung einen einzelnen Isolationskör¬ per, FIG 3 einen teilweise montierten Metallclip2 shows a single insulation body in the same representation, FIG. 3 shows a partially assembled metal clip
FIG 4 eine Einzelansicht eines Metallclips4 shows a single view of a metal clip
Die Erfindung beruht im wesentlichen darauf, das Metallgehäu¬ se aus zwei Blechstanzteilen zusammenzusetzen, die zusammen mit einem Isolationskörper durch die beschriebene Geometrie zu einer funktionalen Einheit verbunden sind.The invention is essentially based on assembling the metal housing from two stamped sheet metal parts which, together with an insulation body, are connected to form a functional unit by the geometry described.
FIG 1 zeigt ein Gehäuseteil 1, das den mit acht Kontaktfedern bestückten Isolationskörper 3 bis auf die Steckseite komplett umschließt, sowie einen Metallclip 2, der mittig zwischen den Seitenwänden des Gehäuseteils 1 plaziert ist und das Steckge¬ sicht in zwei separate Steckplätze unterteilt. Jeweils zwei Rasthaken 4 des Gehäuseteils 1 und zwei Rasthaken 4 des Me¬ tallclips ragen in die Stecköffnungen und können einen einge- steckten Kabelstecker bis zu einer Maximalziehkraft festhal¬ ten.1 shows a housing part 1, which completely encloses the insulation body 3 equipped with eight contact springs except for the plug side, and a metal clip 2, which is placed in the middle between the side walls of the housing part 1 and divides the plug face into two separate slots. Two latching hooks 4 of the housing part 1 and two latching hooks 4 of the metal clip each protrude into the plug-in openings and can hold an inserted cable plug up to a maximum pulling force.
Der Metallclip 2 muß im Steckverbinder genau positioniert und fixiert werden. Zur Positionierung dient neben den Seitenwän- den des Gehäuseteils 1 (horizontale Positionierung) vor allem ein Kunststoffsteg 5, vgl. FIG 2^am Isolationskörper 3. Er positioniert den Metallclip 2 in vertikaler Richtung und in Montagerichtung, wie auch aus FIG 3 hervorgeht. Dadurch re¬ sultiert eine definiert Bestücktiefe des Metallclips 2. In die zwei Aussparungen 6 oberhalb und unterhalb des Steges 5 hakt der Metallclip 2 ein und wird gegen Herausziehen, also gegen die Ziehkräfte des Kabelsteckers gesichert. Die Ausspa¬ rungen "ψ im Steg 5 ermöglichen die freie Bewegung der Rastha¬ ken 4 beim Einstecken des Kabelsteckers.The metal clip 2 must be precisely positioned and fixed in the connector. In addition to the side walls of the housing part 1 (horizontal positioning), a plastic web 5 is used for positioning, cf. FIG 2 ^ on the insulation body 3. It positions the metal clip 2 in the vertical direction and in Assembly direction, as also shown in FIG 3. This results in a defined insertion depth of the metal clip 2. The metal clip 2 hooks into the two recesses 6 above and below the web 5 and is secured against being pulled out, that is, against the pulling forces of the cable connector. The recesses " ψ in the web 5 allow the detent hooks 4 to move freely when the cable connector is inserted.
Der in FIG 4 einzeln dargestellte Metallclip besitzt neben den vier Rasthaken 4 außerdem vier federnde Elemente 7, die im fertig montierten Stecker gegen die Seitenwände 8 und 9 des Gehäuseteils 1 drücken und für die elektrische Verbindung zwischen Clip 2 und dem Gehäuseteil 1 sorgen. Die vier Wider¬ haken 10 graben sich in die Seitenwände 8 und 9, die zwei Ausprägungen 11 oben bzw. unten in die Aussparungen des Iso¬ lationskörpers 3 ein und halten den Metallclip 2 im Isolati¬ onskörper 3 fest. The metal clip shown individually in FIG. 4 has, in addition to the four latching hooks 4, also four resilient elements 7 which press against the side walls 8 and 9 of the housing part 1 in the fully assembled plug and ensure the electrical connection between clip 2 and the housing part 1. The four barbs 10 dig into the side walls 8 and 9, the two forms 11 above and below into the recesses of the insulation body 3 and hold the metal clip 2 in the insulation body 3.
