Abstract
This invention relates to two-part electrical coupling connectors for use with audio cables, and in particular to a means by which insulated conductors of the cable are connected to contact elements of the coupling connector.
Claims21
An electrical connector element for a sheathed cable containing a locally insulated conductor, said connector element comprising:
- a body member having a forwardly-extending contact element arranged therein and an opposite end that terminates in a rearwardly-extending insulation-penetrating means;
- a cup-shaped end member having a side wall and a rear wall for defining an inner space and a co-axial hole for receiving said sheathed cable therethrough, and having means for releasably coupling said cup-shaped end member and said body member;
- and
- a mateable insulated-wire terminal means being arranged in the inner space of said cup-shaped end member, having a guide-slot means for receiving said locally insulated conductor, having a slot for receiving said rearwardly-extending insulation-penetrating means when said forwardly-extending contact element and said rearwardly-extending insulated wire terminal means are axially mated, and having a cable gripping means with two rearwardly extending longitudinal limbs for gripping said sheathed cable when said cup-shaped end member and said body member are coupled, at least one of said limbs being hingeable;
- whereby when said cup-shaped end member and said body member are de-coupled said cable gripping means releases said sheathed cable.

An electrical connector element for a sheathed cable containing at least one insulated conductor, said connector element comprising:
- an assembly of an outer shell member in which is fixedly located an insert member having fixedly supported within its boundary at least one forwardly-extending contact element whose opposite end terminates in a rearwardly-extending insulation-penetrating means;
- a mateable insulated-wire terminal means including at least one slot arranged to receive said insulation penetrating means when said contact element housing and said insulated wire terminal means are axially mated, and an insulated wire guide means arranged transverse said slot;
- a cup-shaped end member having a side wall joined by an end wall in which is provided a co-axial hole for receiving said sheathed cable therethrough and coupling means for releasably coupling said end member and said shell member;
- said insulated wire terminal means including a cable gripping means having two longitudinal limbs extending rearwardly from said insulated-wire terminal means to form a pair of jaws, at least one limb being hinged by hinge means;
- and
- one of the two said limbs being provided intermediate its length with an inwardly extending protuberance opposite a space defined by two raised shoulders that extend inwardly from the other said limb, whereby when an end section of said cable is laid longitudinally between said limbs and a length of exposed at least one insulated conductor laid in said guide means, a part of said end section bridges said space such that upon closing said jaws, mating said contact element housing and said insulated-wire terminal means, and coupling said end member and said shell member, said part of said end section of said cable is pinched and gripped between said shoulders and said protuberances, and said insulation-penetrating means cuts the insulation of said at least one insulated wire in said guide means to provide electrical connection between said insulated wire and said contact element.
