Cutting and clamp sleeve contact and method of connecting insulated electrical wire conductors

A cutting and clamping sleeve contact for clamping and contacting a cable wire transverse to a sleeve axis, in particular for cable wires and telecommunications, comprising a metallic sleeve defining at least one insulation clamping slot with clamping edges extending downwardly and axially along its periphery and including cutting and clamping contacts at the interior of said sleeve, said cutting and clamping contacts being formed between inwardly bent wall pieces cut away from said sleeve and made of the same conductive metal material forming inwardly projecting legs with contact edges which are spaced apart and spaced to form said cutting and clamping contacts, engagement of a cable wire with said clamping slot urging said clamping edges apart causing said contact edges of said bent wall pieces to spread apart prior to engagement of the cable wire with said contact edges.

An electrical connector for use with insulated cable wire conductors comprising:

• first and second tubular wall portions;
• first and second wall pieces, and, spring means connected to each of said first and second wall pieces and connected to said first and second tubular wall portions, said spring means providing a spacing between said first and second wall pieces thereby defining a contact slot and providing a spacing between said first and second tubular wall portions thereby defining a clamping slot, said spring means for providing a widening of said contact slot upon engaging an insulated wire with said clamping slot, prior to engaging the insulated wire with said contact slot, thereby providing a prewidening of said clamping slot proportional to a widening of said clamping slot.

A method of establishing an electrical connection and a clamping of an electrically insulated wire conductor using a tubular member with walls defining a clamping slot along the surface thereof and an interior with spaced-apart clamping and conducting walls defining a contact slot, comprising providing a connection between the tubular member and each of the spaced apart conducting walls such that movement of the walls defining the clamping slot upon the insulated wire engaging the clamping slot, moves the spaced apart clamping and conducting walls a proportional amount prior to the insulated wire engaging the contact slot such that the width of the clamping slot determines the width of the contact slot placing the wire so that it is aligned with the prewidened contact slot and moving the wire downwardly in the contact slot so as to position the wire between the edges of the spaced apart conducting walls, pressing the wire downwardly so that the edges of the wall penetrate through the insulation so as to engage and electrically connect and clamp the conductor in the wire.
