Abstract

Abstract An electrical contact for stripless cable connections comprising a front contacting part and a rear channel-shaped part of U-shaped cross-section. A fork is cut off from the base of a channel-shaped rear part of the contact and bent upwardly at right angles between the lateral walls of the channel. The branches of the fork define insulation severing, core penetrating jaws. The lateral walls of the channel prevent spreading of the jaws when a cable is forced therebetween to be electrically connected to the contact. A rearwardly extending contact retention tongue is also formed in the base where the fork is cut therefrom and is bent outwardly for engagement with a shoulder in an insulator in which the contact is mounted.

Claims Analysis

Total Claims: 6
Claim 1
Independent Claim 120 words
An electrical contact for making electrical connection to a cable core without stripping the insulation sheath from the core comprising: a front contacting part and a rear part; said rear part including a flat base; stripless cable connection means comprising a fork cut from said base and bent upwardly therefrom, said fork including a pair of spaced branches defining opposed insulation-severing core penetrating jaws; and an outwardly bent rearwardly extending contact retention tongue cut from said base and having a configuration complementary to the opening defined between said branches of said fork, said tongue lying within said opening prior to bending said fork upwardly from said base whereby said tongue and fork may be formed by a single cutting operation.
Claim 2
Dependent Claim 120 words
An electrical contact for making electrical connection to a cable core without stripping the insulation sheath from the core comprising: a front contacting part and a rear part; said rear part including a flat base; stripless cable connection means comprising a fork cut from said base and bent upwardly therefrom, said fork including a pair of spaced branches defining opposed insulation-severing core penetrating jaws; and an outwardly bent rearwardly extending contact retention tongue cut from said base and having a configuration complementary to the opening defined between said branches of said fork, said tongue lying within said opening prior to bending said fork upwardly from said base whereby said tongue and fork may be formed by a single cutting operation.
Claim 3
Dependent Claim 227 words
An electrical contact for making electrical connection to a cable core without stripping the insulation sheath from the core comprising: a front contacting part and a rear channel-shaped part having a generally U-shaped cross-section; said rear part including a base and a pair of lateral walls; stripless cable connection means comprising a fork cut from said base and bent upwardly therefrom between said lateral walls, said fork including a pair of spaced branches defining opposed insulation-severing, core penetrating jaws, said walls restricting spreading of said jaws when a cable is forced therebetween; strain relief means integrally formed on said rear part behind said fork, said strain relief means comprising a second fork at the rear of said rear part folded upwardly from said base and disposed generally parallel to said first fork, said forks being generally vertical with respect to said base, said second fork including a pair of spaced branches defining opposed insulation severing jaws, said insulation severing jaws being spaced apart further than said core penetrating jaws for severing the insulation sheath of a cable without necessarily penetrating the core thereof when a cable is forced between said two pairs of jaws; and the rear ends of said lateral walls being bent inwardly behind said second fork to retain said second fork in its vertical position when a cable is pulled rearwardly in the contact.
Claim 4
Dependent Claim 227 words
An electrical contact for making electrical connection to a cable core without stripping the insulation sheath from the core comprising: a front contacting part and a rear channel-shaped part having a generally U-shaped cross-section; said rear part including a base and a pair of lateral walls; stripless cable connection means comprising a fork cut from said base and bent upwardly therefrom between said lateral walls, said fork including a pair of spaced branches defining opposed insulation-severing, core penetrating jaws, said walls restricting spreading of said jaws when a cable is forced therebetween; strain relief means integrally formed on said rear part behind said fork, said strain relief means comprising a second fork at the rear of said rear part folded upwardly from said base and disposed generally parallel to said first fork, said forks being generally vertical with respect to said base, said second fork including a pair of spaced branches defining opposed insulation severing jaws, said insulation severing jaws being spaced apart further than said core penetrating jaws for severing the insulation sheath of a cable without necessarily penetrating the core thereof when a cable is forced between said two pairs of jaws; and the rear ends of said lateral walls being bent inwardly behind said second fork to retain said second fork in its vertical position when a cable is pulled rearwardly in the contact.
Claim 5
Dependent Claim 148 words
An electrical contact for making electrical connection to a cable core without stripping the insulation sheath from the core comprising: a front contacting part and a rear channel-shaped part having a generally U-shaped cross-section; said rear part including a base and a pair of lateral walls; stripless cable connection means comprising a fork cut from said base and bent upwardly therefrom between said lateral walls, said fork including a pair of spaced branches defining opposed insulation-severing, core penetrating jaws, said walls restricting spreading of said jaws when a cable is forced therebetween; and an outwardly bent rearwardly extending contact retention tongue cut from said base and having a configuration complementary to the opening defined between said branches of said fork, said tongue lying within said opening prior to bending said fork upwardly between said walls whereby said tongue and fork may be formed by a single cutting operation.
Claim 6
Dependent Claim 148 words
An electrical contact for making electrical connection to a cable core without stripping the insulation sheath from the core comprising: a front contacting part and a rear channel-shaped part having a generally U-shaped cross-section; said rear part including a base and a pair of lateral walls; stripless cable connection means comprising a fork cut from said base and bent upwardly therefrom between said lateral walls, said fork including a pair of spaced branches defining opposed insulation-severing, core penetrating jaws, said walls restricting spreading of said jaws when a cable is forced therebetween; and an outwardly bent rearwardly extending contact retention tongue cut from said base and having a configuration complementary to the opening defined between said branches of said fork, said tongue lying within said opening prior to bending said fork upwardly between said walls whereby said tongue and fork may be formed by a single cutting operation.
