Abstract

Abstract A solderless connector having a plurality of contacts with provision for strain relief. The two-part connector has a first half in which a plurality of bifurcated contacts are disposed to extend upwardly therefrom. The second half includes wire receiving slots, a strain relief member that extends into a recess in the first member and a like plurality of tapered apertures in registration with the bifurcated contacts.

Claims Analysis

Total Claims: 4
Claim 1
Independent Claim 201 words
A solderless connector comprising in combination; a base member having a top surface and including a plurality of contact receiving apertures disposed normal to said top surface; contact means disposed in at least one of said apertures in said base, said contact means including a pair of upwardly extending legs adapted to conductively engage an electrical conductor, the legs on said contact means having inner opposed portions in parallelism prior to engagement with a conductor; a cover member having a bottom surface and a like plurality of apertures and adapted to be removably disposed on said base with respective apertures in registration, the apertures in said cover being tapered so that the ends adjacent the bottom surface are larger than the ends remote from said bottom surface whereby assembly of said cover on said base causes the inner portions of the contact means to assume and retain a non-parallel disposition so that a conductor held therebetween is subjected to an increasing contact pressure as said cover is disposed on said base, and the cover member includes channel portions extending from the outer surfaces thereof to said apertures in which the channels extend between two non-parallel outer faces of the cover member.
Claim 2
Dependent Claim 201 words
A solderless connector comprising in combination; a base member having a top surface and including a plurality of contact receiving apertures disposed normal to said top surface; contact means disposed in at least one of said apertures in said base, said contact means including a pair of upwardly extending legs adapted to conductively engage an electrical conductor, the legs on said contact means having inner opposed portions in parallelism prior to engagement with a conductor; a cover member having a bottom surface and a like plurality of apertures and adapted to be removably disposed on said base with respective apertures in registration, the apertures in said cover being tapered so that the ends adjacent the bottom surface are larger than the ends remote from said bottom surface whereby assembly of said cover on said base causes the inner portions of the contact means to assume and retain a non-parallel disposition so that a conductor held therebetween is subjected to an increasing contact pressure as said cover is disposed on said base, and the cover member includes channel portions extending from the outer surfaces thereof to said apertures in which the channels extend between two non-parallel outer faces of the cover member.
Claim 3
Dependent Claim 223 words
A solderless connector comprising in combination; a base member having a top surface and including a plurality of contact receiving apertures disposed normal to said top surface; contact means disposed in at least one of said apertures in said base, said contact means including a pair of upwardly extending legs adapted to conductively engage an electrical conductor, the legs on said contact means having inner opposed portions in parallelism prior to engagement with a conductor; a cover member having a bottom surface and a like plurality of apertures and adapted to be removably disposed on said base with respective apertures in registration, the apertures in said cover being tapered so that the ends adjacent the bottom surface are larger than the ends remote from said bottom surface whereby assembly of said cover on said base causes the inner portions of the contact means to assume and retain a non-parallel disposition so that a conductor held therebetween is subjected to an increasing contact pressure as said cover is disposed on said base, the cover member includes channel portions extending from the outer surfaces thereof to said apertures and between two non-parallel outer faces of the cover member, the cover member includes a centrally disposed portion extending downwardly from its lower surface and the top surface of the base has a recess in registration therewith.
Claim 4
Dependent Claim 223 words
A solderless connector comprising in combination; a base member having a top surface and including a plurality of contact receiving apertures disposed normal to said top surface; contact means disposed in at least one of said apertures in said base, said contact means including a pair of upwardly extending legs adapted to conductively engage an electrical conductor, the legs on said contact means having inner opposed portions in parallelism prior to engagement with a conductor; a cover member having a bottom surface and a like plurality of apertures and adapted to be removably disposed on said base with respective apertures in registration, the apertures in said cover being tapered so that the ends adjacent the bottom surface are larger than the ends remote from said bottom surface whereby assembly of said cover on said base causes the inner portions of the contact means to assume and retain a non-parallel disposition so that a conductor held therebetween is subjected to an increasing contact pressure as said cover is disposed on said base, the cover member includes channel portions extending from the outer surfaces thereof to said apertures and between two non-parallel outer faces of the cover member, the cover member includes a centrally disposed portion extending downwardly from its lower surface and the top surface of the base has a recess in registration therewith.
