Insulation displacement connector system

An insulation displacement connection system, comprising

• a connection terminal equipped with at least one inner tab,
• a pocket able to accommodate said connection terminal,
• a wire wound in a spiral and lodged at least partially in said pocket,
• wherein the pocket comprises at least one central pin which said wire is wound and inserted on,
• the at least one inner tab being shaped to elastically intercept the central pin, so as to exert an abrasive effect on the wire during the insertion of the connection terminal in the pocket and to elastically influence the wire against the central pin following the insertion of said terminal in the pocket, ensuring electrical connection between the at least one tab and the wire, wherein
• the central pin is defined by lateral walls which support the enamel insulated wire during winding of the same onto the central pin, the central pin comprising a centre line plane,
• the inner tabs have respectively inner walls suitable to intercept the wire, said inner walls having, in relation to a cross-section perpendicular to the centre line plane, a rectilinear wall which interfaces directly with the enamel insulated wire, and
• the lateral walls of the central pin being counter-shaped to the rectilinear wall of the inner walls so as to abrade the enamel coating of the wire in a gradual and progressive manner.
