Abstract
Abstract A cam actuated connector assembly is disclosed for effecting a low insertion force mating of the connector assembly with a plurality of fixed pin or post terminals. The housing includes a first housing member adopted to hold therein a plurality of spring contact terminals and a second housing member receiving the first housing member therein with cam means therebetween for effecting relative movement of the housing members. In the normal relaxed condition of the connector assembly, the contacts are in a closed configuration. Upon actuation of the connector assembly for mating, the housing members are moved relative to one another by the cam means causing the contact terminals to be moved to an open position to receive the mating pin or post terminals. The subsequent release of the second housing member effects a closing of the terminals to an engaged condition.

Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
232 words
A connector assembly for zero on/zero off mating with a plurality of fixed post terminals, said connector assembly comprising: a first housing member having a mating face on a front end, a cavity depending into an opposite rear end, a plurality of profiled terminal passages extending from said mating face to said cavity including at least one reaction surface facing said cavity, a pair of parallel spaced apart handles resiliently attached to said first housing member extending rearwardly on opposite sides of said cavity, and cam surfaces on the opposed surface of said handles; a second housing member profiled to be received in said cavity, a plurality of profiled contact receiving passages in said second housing member each aligned with a respective terminal passage in said first housing member, and a pair of oppositely directed cam surfaces aligned to react with said cam surfaces on the handles of said first housing member to effect relative motion between said housing members; and a plurality of spring contacts each having a first end profiled for engagement with a conductor and second mating end including at least one spring arm having a normal relaxed first position, said arm engaging said reaction surface of said first housing member upon relative closing movement of said housing members and being deflected to a second position allowing insertion of a terminal post into said assembly without application of force.
Claim 2
Dependent Claim
232 words
A connector assembly for zero on/zero off mating with a plurality of fixed post terminals, said connector assembly comprising: a first housing member having a mating face on a front end, a cavity depending into an opposite rear end, a plurality of profiled terminal passages extending from said mating face to said cavity including at least one reaction surface facing said cavity, a pair of parallel spaced apart handles resiliently attached to said first housing member extending rearwardly on opposite sides of said cavity, and cam surfaces on the opposed surface of said handles; a second housing member profiled to be received in said cavity, a plurality of profiled contact receiving passages in said second housing member each aligned with a respective terminal passage in said first housing member, and a pair of oppositely directed cam surfaces aligned to react with said cam surfaces on the handles of said first housing member to effect relative motion between said housing members; and a plurality of spring contacts each having a first end profiled for engagement with a conductor and second mating end including at least one spring arm having a normal relaxed first position, said arm engaging said reaction surface of said first housing member upon relative closing movement of said housing members and being deflected to a second position allowing insertion of a terminal post into said assembly without application of force.
Claim 3
Dependent Claim
32 words
A connector assembly according to claim 1 wherein said first housing member further includes an outer profile for polarized mating with a member having a plurality of terminal posts fixedly mounted thereon.
Claim 4
Dependent Claim
49 words
A connector assembly according to claim 1 wherein said first housing member includes at least one elongated slot; and said second housing member includes at least one integral stud aligned to extend into said slot whereby said housing members are properly aligned and the relative movement therebetween is defined.
Claim 5
Dependent Claim
26 words
A connector assembly according to claim 1 wherein said first end of each said contact includes means for effecting crimped on engagement with an electrical conductor.
Claim 6
Dependent Claim
26 words
A connector assembly according to claim 1 wherein said first end of each said contact includes means for effecting insulation displacing engagement with an electrical conductor.
Claim 7
Dependent Claim
56 words
A connector assembly according to claim 1 wherein said at least one spring arm is a cantilever beam having an elongated aperture adjacent the free end thereof, engagement of said beam with said reaction surface of said first housing member deflecting said beam sufficiently to align said aperture with said aperture in said first housing member.
Claim 8
Dependent Claim
79 words
A connector assembly according to claim 1 wherein said at least one spring arm further comprises a pair of opposed arms extending from opposite side walls of a channel configuration, said arms normally engaging at their free ends, said reaction surface of said first housing member further comprising a pair of intersecting inclined surfaces which cause said arms to spread apart upon relative together movement of said housing members thereby allowing free passage therebetween of a mating terminal pin.
Claim 9
Dependent Claim
185 words
A low insertion force connector assembly comprising: a first housing member having a mating front face, a plurality of terminal pin receiving passages in said mating face, at least one reaction surface on the end of said passages toward the rear of said housing member, a pair of handle members resiliently attached in parallel spaced relation extending from the rear of the housing member with camming surfaces on the opposed faces of each said handle, a second housing member having a like plurality of contact carrying passages each aligned with a respective passage in said first housing member and cam surface means aligned to react with said camming surfaces of said first housing member to cause relative linear motion between said housing members; and a like plurality of contacts each mounted in a respective passage of said second housing member and having a first end portion adapted to electrically and mechanically engage a conductor and a second mating end portion which engages said reaction surface of the first housing member and is acted thereupon to condition it for receipt therein of a fixed terminal post.
Claim 10
Dependent Claim
185 words
A low insertion force connector assembly comprising: a first housing member having a mating front face, a plurality of terminal pin receiving passages in said mating face, at least one reaction surface on the end of said passages toward the rear of said housing member, a pair of handle members resiliently attached in parallel spaced relation extending from the rear of the housing member with camming surfaces on the opposed faces of each said handle, a second housing member having a like plurality of contact carrying passages each aligned with a respective passage in said first housing member and cam surface means aligned to react with said camming surfaces of said first housing member to cause relative linear motion between said housing members; and a like plurality of contacts each mounted in a respective passage of said second housing member and having a first end portion adapted to electrically and mechanically engage a conductor and a second mating end portion which engages said reaction surface of the first housing member and is acted thereupon to condition it for receipt therein of a fixed terminal post.
