An electrical connector includes at least two electrical connector elements extending side by side along a longitudinal direction, each of the electrical connector elements being connectable to a respective wire of an associated electrical cable. An electrical device is in electrical contact with the respective electrical connector elements. A flexible carrier surrounds the electrical connector elements annularly in cross section, and the electrical device is mounted on an inner side of the flexible carrier which faces the connector elements.

A device for rendering safe a detonator firing circuit by short circuiting multiple conductors in the circuit includes a base portion and cable piercing members. The base portion has a cylindrical block and apertures for retentively receiving the cable piercing members. The cable piercing member has a first end to impinge on and penetrate a cable insulation when forcibly attached to an external surface of the cable. The cable piercing member has a low electrical resistance and impedance to generate a short circuit between conductors of the cable. Also, a method for rendering safe a detonator firing circuit of by short circuiting multiple conductor cables or a pigtail connector of a detonator system.

This disclosure provides a method and apparatus for connecting and disconnecting a first wire to a second wire. More specifically, an apparatus that includes a first electrical contact, a second electrical contact, an insulated housing, and a male contact prong (i.e., a shunt) is disclosed. In an embodiment, the first and second electrical contacts conductively connect with a first and second wire, respectively, via an insulation displacement connector. Furthermore, the male contact prong conductively connects (i.e., shunts) the first and second electrical contacts together. A wire-to-wire contact with shunt allows for two wires to be quickly and efficiently connected and disconnected.

An insulation displacement contact device comprises a blade assembly and a biasing element. The blade assembly has a plurality of blades disposed opposite one another each with a cutting edge. The cutting edges of the blades terminate into a contact slot disposed between the blades. The blade assembly is disposed in the biasing element. The biasing element is movable with respect to the blade assembly along a moving direction parallel to the contact slot.
