- FIG. 1 is a cross-section of a connector and mating connector element according to the prior art
- FIG. 2 is a cross-section of a connector device according to a preferred embodiment of the invention.
- FIG. 3 is a view of a connector element according to a second preferred embodiment of the invention.
- FIG. 4 is a cross-section of a connector device according to a third preferred embodiment of the invention.
- FIG. 5 is a cross-section of a connector device in which the contact element is capable of assuming two positions according to a fourth preferred embodiment of the invention.
- FIG. 6 is a cross-section of a connector device in which the contact element is capable of assuming two positions according to a fifth preferred embodiment of the invention.
- FIG. 7 is a perspective view of a spacer suitable for use in the connectors as shown in FIGS. 5 and 6.
- FIG. 1 shows a typical connector of the prior art having a male connector element such as a circuit board I mounted therein.
- a U-shaped contact element 6 having two arms 10 is mounted within a slot in an insulated body 2.
- the contact arms 10 have contact portions 11 for contacting the circuit board 1.
- the connector element 6 is held in the slot by two guides 9 and a catch 8 and has a connection terminal 7 extending through the rear of the body 2.
- the distance between the contact portions 11 depends upon the nominal thickness of circuit board 1 whose actual thickness will vary because of manufacturing tolerances. Likewise, the actual width of the opening 3 which must be capable of accommodating circuit boards of maximum thickness with adequate clearance, will vary from a nominal dimension because of manufacturing tolerances.
- a circuit board of minimum thickness is introduced into the opening 3, as shown in FIG. 1, and the board is in contact with one of the sides of opening 3, one of contact portions 11 is pushed away from the other contact portion 11 resulting in a clearance 12 between the conductors 5 on the circuit board and the mating contact portion 1 1. In this situation, a proper electrical contact will not be made.
- Prior art connectors which do not have a terminal 7 rigidly mounted in body 2 by catch 8 and guides 9 are not suitable for use with pin connectors on a matrix board or for use with connectors for rolled up connection or clips, since terminals which are closely positioned are required for these applications and the random movement of individual pins or clips to adapt to the manufacturing tolerances of the mating connector precludes desirable close packing of contacts.
- FIG. 2 shows a preferred embodiment of the electrical connector according to the present invention having a contact element 28 mounted in a body 24 of insulating material.
- a male connector element such as a circuit board or a pin is inserted into opening 26 of body 24.
- a printed circuit board In order to simplify the description, only the embodiment using a printed circuit boardwill be considered.
- the printed circuit board 20 has a side 22 on which the conductors to be connected are mounted, and a side 21 without any conductors. Beveled edges 23 may be provided to facilitate the insertion of the circuit board into the opening 26.
- Contact element 28 of electrically conductive material is mounted in slot 25 of the connector body 24 and intersects a rearwardly disposed portion of opening 26 at an angle of approximately 90.
- Contact element 28 has a base and a rearward projecting terminal 29 suitable for making connections with an external electrical circuit.
- a rigid blade portion 36 extends forwardly from the base 30 and terminates in a hook which is inserted into a mating notch 41 that is molded in the body 24. Hook 40 is formed by bending blade 36 after contact 28 is inserted into slot 25. Edges 39 of base portion 30 are accommodated in recesses 42 of slot 25. In this manner, the base 30 and connecting terminal 29 are rigidly mounted in body 24.
- the contact element 28 has two arms 35 and 38 which are joined to form a U-shape.
- a flexible blade portion 34 connects the forward extension of arm 35 to the upper portion of base 30 resiliently coupling arms 35 and 38 to base 30.
- a long resilient blade 37 joins the forward end of rigid blade 36 with the rearward end of arm 35 at location 43 adjacent to junction with central resilient blade which is resiliently coupled to contact portion 32.
- An electrical contact portion 32 is provided on the forward end of arm 38, and a contact positioning portion 31 is provided on the forward end of arm 35 with I portions 31 and 32 being laterally spaced-apart and offset from the axis of opening 26 towards contact portion 31. The distance between contact portions 31 and 32 is defined by the contact pressure desired to guarantee a reliable connection.
- Blades 34 and 37 extend from respective adjacent sections of arms 35 and 38 in a side by side generally parallel relationship to beyond each respective section to base 30.
- Axis 57 is equally distant from contact portions 31 and 32 and is displaced from the symmetry axis longitudinal axis of the opening 26 in a direction towards internal face 46 of the opening.
- Circuit board 20 may have beveled edges 23, and slot 26 may have beveled edges 27 on the forward portion in order to facilitate the insertion of circuit board 20 into slot 26.
- circuit board 20 When circuit board 20 is inserted into slot 26, the edge 23 engages slope 33 at the upper end of arm 35.
- the insertion force creates a reactive force which bends the resilient blade 34 until positioning portions 31 engages side 21 of circuit board 20.
- Arm 35 which holds arm 38 at its lower portion, is rigid and is not deformed. Therefore, electrical. contact portion 32 on arm 38 is kept at the same distance from positioning portion 31.
- Resilient blade 37 which is held by arm,35 does undergo some elastic deformation.
- a base 47 of the contact element can be twisted to hold it in the socket of the connector, and the U-shaped arms are joined with base 47 by a single resilient blade 48.
- base 53 of the contact element is mounted in a body 49 so that shoulders 55 provided at the base engage corresponding seats in the body.
- the intregal blades 52 of base 53 carry stubs 56 which are used as attachment members.
- a resilient blade 50 joins the lower end of one of the arms of the contact element 51-with one of the blades 52.
- a terminal 54 extends from the base 53.
- FIG. 5 shows a modification of the embodiment shown in FIG. 4 in which the contact element is capable of assuming two different positions within the body 133.
- Contact element 125 is mounted in slot 137 of body 133 and consists of two arms joined to form a U-shaped element 126 which is attached to base 127 by means ofa resilient blade 124.
- Base 127 is inserted into slot 137 and is provided with two blades 128 having stubs 131 which serve to hold the contact element 125 as explained below.
- Base 127 has a rearward extension 123 which forms a terminal for external electrical connections.
- the distance between shoulders 132 and 138 is equal to the distance between surface 136 and support 143 less the thickness of base 127. The distance between shoulders 132 and 138 is sufficient to insure two separate settings suitable for either a first circuit position or a second circuit position.
