ABSTRACT:
An electrical terminal having a wire clamping tab connected thereto by an essentially thin neck portion about which a wire coated with a resin-type, high temperature insulation is adapted to be wound so that, when the tab is bent back against the terminal by opposed, energized electrodes to clamp a portion of the wire extending from the neck portion therebetween, resistance of the latter to flow of current heats both the neck portion and the wire wrapped therearound sufficiently to explode the insulation from the wire to assure a good electrical connection. At the same time the relatively large area of the terminal and its clamping tab maintains the clamped portion of the wire below its annealing temperature so that it is resistant to breakage in use.
