ABSTRACT:
An electrical contact member formed from an axially extended tube is provided intermediate its ends with an axially extending insulation-opening slot. The slot is terminated at one end in an entry opening through the tube. The entry opening and an inwardly tapered entry ramp are formed by a free-ended piece of the tube wall bent into the inner opening of the tube. An insulated conductor may be inserted into the contact member in either of two ways: by insertion through the appropriate end of the tube and deflection by the entry ramp through the entry opening; or, by insertion through the entry opening and deflection by the entry ramp through the end of the tube. After insertion by either method, the ends of the insulated conductor may be pulled to force the conductor into a narrowed engagement portion of the slot where the insulation around the conductor is opened by spreading or cutting and electrical contact is made between the tube and the metallic conductor. The tube at a section apart from the slot may be crimped to secure the conductor after the conductor is positioned in the slot. A contact member or plurality of contact members may be assembled with insulating means to form a connector.
