Definitions
- the present invention relates to electrical connectors and more particularly to electrical connectors for use with printed circuit boards.
- Printed circuit boards are equipped with conductive pads. Such circuit boards fit edgewise to engage slots in connector assemblies which are equipped with a plurality of resilient terminals. These terminals engage the pads on the circuit board to achieve electrical connection between the assembly and the circuit board.
- Various means have been suggested for latching and ejecting the circuit board from the assembly. Problems have, however, continued with regard to the ease of ejectment and the security of the latching.
- a mechanism which is pivotally connected to the housing and which has an upper arm and a lateral ejectment arm.
- a resilient latch which engages a semi-circular medial recess at the edge of the circuit board and which extends back upwardly and outwardly to provide a convenient surface for disengaging the latch from the recess.
- Fig. 1 is a plan bottom view of the assembly
- Fig. 2 is a side elevational view of the assembly in which the circuit board is engaged and shown in broken lines;
- Fig. 3 is a vertical cross sectional view of the assembly taken through line
- Fig 4 is an enlarged side view of only the latch mechanism
- Fig. 5 is an end view of the latch mechanism shown in Fig. 4;
- Fig. 6 is an enlarged cross sectional view taken through line VI-VI in Fig. 2;
- Fig. 7 is an enlarged cross sectional view of the latch mechanism taken through line VII-VII in Fig. 2.
- the assembly of the present invention includes a molded insulative housing shown generally at numeral 10.
- This housing has a first end 12 and an opposed second end 14, a top side 15 and a bottom side 16, as well as a first longitudinal side 18 and a second longitudinal side 20. Interposed between these longitudinal sides in the topside there is a longitudinal groove 22 for receiving the circuit board which is shown generally at numeral 23 and which rests on board rest 24.
- the housing is connected to a mother circuit board 33 by means of leads (not shown) and is spaced from the board by stand offs as at 35 and 36.
- the circuit board 24 includes a first end 37 and an opposed second end 38 and a top edge 40 and a front edge 42.
- the circuit board includes a number of conductive pads (not shown) by which it is connected to the contact elements.
- first latching mechanism shown generally at numeral 44 and a second latching mechanism shown generally at numeral 46.
- Each of these latching mechanisms include respectively an upper arm 48 and 49 each having respectively reinforcement ribs 50 and 51.
- the first and second latching mechanisms also include respectively lateral ejectment arms 52 and 54. Interposed between these arms on the first and second latching mechanisms are pivot shafts shown respectively at 56 and 57 and 58 and 59. These pivot shafts extend from the housing to engage apertures as at 60 (Fig. 4) in the latching mechanism.
- flexible releases shown generally at numerals 62 and 64.
- These arms also include stop members shown respectively at 66 and 68 and are accommodated in abutting relation adjacent to the circuit board by means of recesses 70 and 72 in the circuit board.
- flexible release 62 comprises an inward leg 74 which extends inwardly from upper engagement arm 48 and which abuts against the circuit board at an inward terminal point 76 and then extends upwardly and outwardly in outward leg 78 which abuts against the recess 70 in an upwardly curved section 80 after which there is a downwardly curved section 82 where the outward leg comes out of contact with the edge of the recess.
- a downward pressure surface 84 At the terminal end of the release there is a downward pressure surface 84.
- On the ejectment arm of the latching mechanism there is an ejectment surface as at 92 (Figs. 3 and 4) which bears against the lower edge of the circuit board.
- the latching mechanism pivots on pivot shaft 56 and 57 in a vertical arc so as to cause this ejectment surface to move the circuit board upwardly and eject it from the assembly.
- the flexible release 62 and the stop 66 are constructed from resilient materials. In the positions shown they are in their compressed positions as when they engage the recess 70 in the circuit board. When they are disengaged from the recess, the release expands upwardly.
- the stop 66 is fixed to upper arm at its lower end 98 but at its upper end 100 it is not fixed so that when it is disengaged from the recess it will expand so that upper end 100 moves away from the upper arm.
