Abstract
Abstract This invention relates to a low-insertion-force electrical connector of the type in which a pair of matable housings (10,110), containing complementary matable contacts or terminals (30,150), are matable by the lateral movement of one housing (10) relative to the other (110). Sufficient safeguards are designed in the system hereof to insure a state of positive mating, or in the alternative, a state of non-mating. The contacts (150) of housing (110) are solder contacts having a first leg (162) for mounting engagement with a circuit board, and a pair of diverging arms (164) projecting in a plane above said first leg, with portions (166) thereof turned inwardly and downwardly and that the endmost portions (168) are bent normal thereto for laterally receiving a male pin member (30) mounted in housing (10). Leverage means (124,126) are provided on housing (110) to effect such lateral movement. The mating/non-mating safeguards include means (156) acting against the movement of lever (124), resistance to such movement of projections (102) into and out of channel (132) and depression (136), and finally the mating resistance of male pin member (30) with femal contact (150).

Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
171 words
A low-insertion-force electrical connector comprising a first housing and a second housing matable therewith, said first housing having a pair of parallel side walls with a plurality of cavities therebetween containing a like plurality of male pin members, and said second housing having a pair of side walls essentially parallel to said first housing side walls, and containing a like plurality of contact elements matable with said male pin members, where said mating is achieved by the movement of said housings in a plane parallel to said side walls, characterized in that said contact elements are solder contacts having a first leg for mounting engagement with a circuit board, and a pair of diverging arms projecting in a plane above said first leg, with portions thereof turned inwardly and downwardly where the endmost portions of said diverging arms are bent normal thereto for laterally receiving one of said male pin members, and leverage means on said housings for moving said housings from an unmated contact position to a mated contact position.
Claim 2
Dependent Claim
171 words
A low-insertion-force electrical connector comprising a first housing and a second housing matable therewith, said first housing having a pair of parallel side walls with a plurality of cavities therebetween containing a like plurality of male pin members, and said second housing having a pair of side walls essentially parallel to said first housing side walls, and containing a like plurality of contact elements matable with said male pin members, where said mating is achieved by the movement of said housings in a plane parallel to said side walls, characterized in that said contact elements are solder contacts having a first leg for mounting engagement with a circuit board, and a pair of diverging arms projecting in a plane above said first leg, with portions thereof turned inwardly and downwardly where the endmost portions of said diverging arms are bent normal thereto for laterally receiving one of said male pin members, and leverage means on said housings for moving said housings from an unmated contact position to a mated contact position.
Claim 3
Dependent Claim
50 words
The low-insertion-force electrical connector of claim 1, characterized in that each said cavity of said first housing contains a pair of opposed and separated partitions between which said male pin member is inserted, and that each said partition contains an inwardly directed projection for engagement with said male pin member.
Claim 4
Dependent Claim
25 words
The low-insertion-force electrical connector of claim 1, characterized in that cooperative means are provided on said housings for locking the housings in an engaged position.
Claim 5
Dependent Claim
46 words
The low-insertion-force electrical connector of claim 1, characterized in that said first housing comprises a first portion and a second portion, said first portion having plural windows along opposing sides thereof for receiving a secondary locking mechanism insertable therethrough into engagement with said male pin members.
Claim 6
Dependent Claim
45 words
The low-insertion-force electrical connector of claim 4, characterized in that each said male pin member includes a mating shank portion and a pair of spaced apart ribs along said shank portion, and that said secondary locking mechanism engages said male pin member between said ribs.
Claim 7
Dependent Claim
47 words
The low-insertion-force electrical connector of claim 4, characterized in that said second portion includes a slot through which said leverage means projects, whereby the movement thereof affects lateral movement of said first housing relative to said second housing and the male pin members with said contact elements.
Claim 8
Dependent Claim
38 words
The low-insertion-force electrical connector of claim 5, characterized in that said secondary locking mechanism comprises plural pairs of arms, where each said pair of arms projects into one of said windows into contact with said male pin member.
