Several modifications of electrical connectors are shown for the quick connection of the bare ends of lead wires including all types of terminals such as flat ring terminals, or flag or right angle push-on terminals. One modification of this connector has a central elongated screw with a lower end that is adapted to be clamped into the hole of an insulating panel by a pair of adjustable nuts. The screw extends vertically from the panel, and it supports an elongated coupling nut that is threaded onto the screw. An inverted conical spring surrounds the coupling nut, where the lower end is the smallest end, and it is seated upon a flat washer. The upper end of the conical spring is the larger end, and it supports a large washer that slips down over the upper end of the coupling nut. A cup washer is seated upon the top of the coupling nut, and the top end of the screw is formed with a screw head that locks the cup washer to the coupling nut. When an electrical connection is to be made, a force is applied at one side edge of the large washer so as to compress the conical spring and pivot the large washer from its opposite side relative to the cup washer so as to capture a lead wire end, or terminal, in the gap formed between the deflected large washer and the cup washer. Another modification is to combine into one element the central screw and the coupling nut and the lower flat washer or hex nut supporting the lower end of the spring. The inverted conical spring may be replaced by a cylindrical spring.
