Abstract

Abstract A spring compression reserve contact element is used in both the female connector and the male connector of a standard type male-female telephone cable connector having parallel wire support channels. The contact element has an elongate wiping contact body and a bifurcate insulation and conductor connection end connected to the contact body coplanar with the adjoining portion thereof, parallel to the contact body and offset from the contact body a distance equal to one-half of the spacing between adjacent wire support channels of the connector.

Claims Analysis

Total Claims: 4
Claim 1
Independent Claim 298 words
A connector comprising: an insulating body formed on one surface with a plurality of parallel wire support channels, each of said channels being formed with a transverse step defining upper and lower wire support levels, adjacent channels being formed with steps rising from generally coplanar lower wire support levels to generally coplanar upper wire support levels in opposite directions lengthwise of said channels to position a lower wire support level between two upper wire support levels, said body being formed with a plurality of apertures therethrough, one aperture extending across the lower wire support level of each said channel, a plurality of spring compression reserve contact elements carried by said body, each said contact element comprising an elongate contact body and a bifurcate insulation stripping and conductor connecting end connected to said contact body coplanar with the adjoining portion thereof, the centerline of the bifurcation lying parallel to the length of said contact body and offset from the centerline of said contact body a distance equal to one-half of the spacing between said wire support channels, a bifurcate contact connecting end of a contact element extending through each said aperture in said body to make electrical connection to a wire supported on each said lower wire support level and terminating below the adjoining upper wire support level with the outer edges of the legs thereof abutting the adjoining upper suport levels of said body, a cover formed on one surface with parallel stepped wire support channels complementary to said channels on said body, and means for retaining said cover on said body with said complementary channels aligned and the wires in the bifurcations of said contact elements to support and retain the wires in said channels and to make electrical connection between said contact elements and the wires.
Claim 2
Dependent Claim 298 words
A connector comprising: an insulating body formed on one surface with a plurality of parallel wire support channels, each of said channels being formed with a transverse step defining upper and lower wire support levels, adjacent channels being formed with steps rising from generally coplanar lower wire support levels to generally coplanar upper wire support levels in opposite directions lengthwise of said channels to position a lower wire support level between two upper wire support levels, said body being formed with a plurality of apertures therethrough, one aperture extending across the lower wire support level of each said channel, a plurality of spring compression reserve contact elements carried by said body, each said contact element comprising an elongate contact body and a bifurcate insulation stripping and conductor connecting end connected to said contact body coplanar with the adjoining portion thereof, the centerline of the bifurcation lying parallel to the length of said contact body and offset from the centerline of said contact body a distance equal to one-half of the spacing between said wire support channels, a bifurcate contact connecting end of a contact element extending through each said aperture in said body to make electrical connection to a wire supported on each said lower wire support level and terminating below the adjoining upper wire support level with the outer edges of the legs thereof abutting the adjoining upper suport levels of said body, a cover formed on one surface with parallel stepped wire support channels complementary to said channels on said body, and means for retaining said cover on said body with said complementary channels aligned and the wires in the bifurcations of said contact elements to support and retain the wires in said channels and to make electrical connection between said contact elements and the wires.
Claim 3
Dependent Claim 80 words
The connector of claim 1 wherein said insulating body is formed on the surface opposite said wire channel surface as a female connector with a central generally rectangular recess with generally vertical interior side walls, and wherein said elongate contact body of each said contact element is supported by said connector body with a portion of one face exposed along said connector body side walls for making wiping contact with a similar contact element carried by a complementary male connector.
Claim 4
Dependent Claim 79 words
The connector of claim 1 wherein said insulating body is formed on the surface opposite said wire channel surface as a male connector with a central generally rectangular rib with generally vertical exterior sidewalls, and wherein said elongate contact body of each said contact element is supported by said connector body with a portion of one face exposed along said connector body side walls for making wiping contact with a similar contact element carried by a complementary female connector.
