Abstract
Abstract Connector intended for attachment to the end of a cable consisting of one or more insulated conductors enclosed by a jacket, said connector comprising two housing parts which in the assembled state together define a passage having a first section designed to take the jacketed end of the cable, and a second section situated further in to take the insulated conductors projecting from the jacket. Both housing parts being provided at the first section with strain relief elements acting on the cable jacket in the assembled state, and one of the housing parts is provided at the second section with a pierce contact for each conductor. One housing part comprises in the second section of the passage cone-shaped teeth which in the assembled state project from the passage wall at right angles to the conductors and extend out to the passage wall of the other housing part in such a way that in the assembled state in the second section of the passage apertures are defined with a passage area which is smaller than the cross sectional area of the insulated conductors, so that a strain relief for each of the insulated conductors is formed.

Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
245 words
A connector intended for attachment to the end of a cable having one or more insulated conductors enclosed by a jacket, said connector comprising: two housing parts which, when assembled, define a passage having a first section adapted to accept the end portion of the cable jacket and a second section adapted to accept the insulated conductors projecting from the jacket, each housing part being provided at the first section of the passage with strain relief means intended to act on the cable jacket, one of said housing parts being provided at the second section of the passage with a pierce contact for each conductor, each said pierce contact being movable from a first position in which the insulated conductors can be introduced unimpeded into the second section of the passage to a second position in which each conductor is at least partially pierced by its respective pierce contact, another of said housing parts being provided at the second section of the passage with cone-shaped teeth which, when the housing parts are assembled, project from the wall of the passage defined by said other housing part into the passage at right angles to the conductors and extend to the wall of the passage defined by said one housing part, said projecting teeth defining apertures in the passage which are smaller than cross-sectional area of the insulated conductors so that the teeth grip the insulation surrounding the conductors, thereby providing strain relief for each insulated conductor.
Claim 2
Dependent Claim
245 words
A connector intended for attachment to the end of a cable having one or more insulated conductors enclosed by a jacket, said connector comprising: two housing parts which, when assembled, define a passage having a first section adapted to accept the end portion of the cable jacket and a second section adapted to accept the insulated conductors projecting from the jacket, each housing part being provided at the first section of the passage with strain relief means intended to act on the cable jacket, one of said housing parts being provided at the second section of the passage with a pierce contact for each conductor, each said pierce contact being movable from a first position in which the insulated conductors can be introduced unimpeded into the second section of the passage to a second position in which each conductor is at least partially pierced by its respective pierce contact, another of said housing parts being provided at the second section of the passage with cone-shaped teeth which, when the housing parts are assembled, project from the wall of the passage defined by said other housing part into the passage at right angles to the conductors and extend to the wall of the passage defined by said one housing part, said projecting teeth defining apertures in the passage which are smaller than cross-sectional area of the insulated conductors so that the teeth grip the insulation surrounding the conductors, thereby providing strain relief for each insulated conductor.
Claim 3
Dependent Claim
17 words
A connector according to claim 1, wherein the projecting teeth are designed as conical bodies of revolution.
Claim 4
Dependent Claim
76 words
A connector according to claim 1 intended for attachment to the end of a flat cable having material which bridges between the conductors, wherein the distance between the projecting teeth corresponds to the distance between the conductors of the flat cable, and wherein the dimensions of the teeth are chosen in such a way that in the assembled state the teeth pass through material between the various conductors without coming into contact with the actual conductors.
Claim 5
Dependent Claim
38 words
A connector according to claim 1, wherein said other housing part provided with the projecting teeth is also provided with one or more reinforcement ribs on its outside wall approximately opposite the teeth projecting from its inside wall.
Claim 6
Dependent Claim
55 words
A connector according to claim 1, wherein the length of the teeth is greater than the corresponding cross sectional dimension of the second passage section, and disposed in the wall of said one housing part are apertures of sufficient depth to take the ends of the teeth when the connector is in the assembled state.
Claim 7
Dependent Claim
78 words
Connector according to claim 5, wherein said apertures in said one housing part are designed as blind bores running from the outside wall of said one housing part to a very short distance from the second passage section and including a partition wall therebetween, the thickness of the partition wall between the end of each blind bore and the second passage section being small enough to be pierced through by the projecting teeth during assembly of the connector.
