Abstract
Abstract A connector for electrically connecting electrical conductors having a housing within which is a holding member containing a preloaded spring, with an insulating cutting edge on the spring and an insulation cutting edge on the holding member, the cutting members acting in opposition on a conductor. Release of the spring, as by flexing the housing causes the cutting edges to cut through the insulation, into electrical contact with the conductor. A similar arrangement of cutting edges is provided for each conductor and a conductive path from one conductor to another is via the spring and/or holding member.

Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
133 words
An electrical connector, comprising: a housing having a base and a cover to define a hollow interior; a holding member in said housing and including a base and flange members extending from a plane including said base; a spring in said holding member, said spring retained in said holding member in a preloaded condition; a first insulation cutting edge on said spring and a second insulation cutting edge on said holding member; said second cutting edge positioned in opposition to said first cutting edge, the cutting edges positioned on opposite sides of a conductor path in said housing; the arrangement such that on release of said spring said first cutting edge is moved toward said second cutting edge with said cutting edges piercing insulation of a conductor and in contact with said conductor.
Claim 2
Dependent Claim
133 words
An electrical connector, comprising: a housing having a base and a cover to define a hollow interior; a holding member in said housing and including a base and flange members extending from a plane including said base; a spring in said holding member, said spring retained in said holding member in a preloaded condition; a first insulation cutting edge on said spring and a second insulation cutting edge on said holding member; said second cutting edge positioned in opposition to said first cutting edge, the cutting edges positioned on opposite sides of a conductor path in said housing; the arrangement such that on release of said spring said first cutting edge is moved toward said second cutting edge with said cutting edges piercing insulation of a conductor and in contact with said conductor.
Claim 3
Dependent Claim
20 words
A connector as claimed in claim 1, said cover hingedly attached to said housing along one side of said base.
Claim 4
Dependent Claim
66 words
A connector as claimed in claim 1, said spring being of bifurcated form and including two legs joined at a joint at one end, said first cutting edge comprising an insulation cutting edge at the other end of each leg; a conductor path along each side of said spring; and a second cutting edge on said holding member opposed to each of said first cutting edges.
Claim 5
Dependent Claim
67 words
A connector as claimed in claim 3, said housing including an inlet at each end, each inlet divided to provide access to said conductor paths, the joint between the legs of said spring adjacent to one inlet, and third cutting edges on said holding member, one for each path, said third cutting edges positioned between said first and second cutting edges and the other of said inlets.
Claim 6
Dependent Claim
37 words
A connector as claimed in claim 3, said legs of said spring being arcuate in form in a released condition, said legs being in contact at positions successively remote from said joint as said legs are preloaded.
Claim 7
Dependent Claim
28 words
A connector as claimed in claim 3, said holding member including means in engagement with said spring at said joint to maintain said spring in said holding member.
Claim 8
Dependent Claim
29 words
A connector as claimed in claim 3, including inwardly extending portions on said flange members of said holding member, said second cutting edges formed on said inwardly extending portions.
Claim 9
Dependent Claim
35 words
A connector as claimed in claim 3, said first cutting edges, on said spring, retained in an aperture in said holding member, said spring released by deflection of said cutting edges out of said aperture.
Claim 10
Dependent Claim
27 words
A connector as claimed in claim 8, said housing being made of flexible material, said spring released by bending of said housing to distort said holding member.
