  • Patent number: 4722579
    Abstract: A novel device and method for making an electrical connection to an insulated wire conductor. The device comprises a conductive tube which has a plurality of spring teeth connected thereto and disposed therein so as to virtually block the tube entirely when the teeth are undeflected. Thus, for example, the spring teeth may be formed in a ring which is then secured inside the tube. In order to further enhance the electrical connection, additional sets of spring teeth may be positioned within the tube along its length in a similar manner. The tube also preferably includes an insulation material covering the exterior surface thereof. Advantageously, a portion of the insulation material adjacent each open end of the tube may be formed into a roll which can be rolled out along the wire conductor after it is inserted into the tube, thereby protecting the electrical connection from exposure to moisture and the elements.
