Filed Aug. 24, 1959, Ser. No. 835,516 1 Claim. (Cl. 29-15555) This invention relates to the joining and splicing of 3,089,223 Patented May 14, 1963 2 “fraying” before installing connector. To “re-open a joint, apply heat to connector and move coil beyond break. To close: reheat and move back, additional solder or flux being unnecessary. In some cases it might be desirable to use pliers in clamping my connector on a wire before soldering. How ever this has the added disadvantage of making the joint more di?icult to disconnect should the need arise. Since my invention is nothing more than a coil of wires by means of a solder connector, and in particular to its use in the repair and maintenance of radio, TV, 10 tinned (solder coated) wire closely surrounding a wire, it provides an usually large area of contact resulting in and electronic devices. Through its use you can quickly an electrical connection that is ‘good and strong both clip a wire, test a suspected part and reconnect, all in mechanically and electrically. As it is so small and in a minimum of time. The resulting joint requires little conspicuous it requires only the very least amount of heat and can very easily be re-opened and closed at will. Although the modern technician has at his disposal a 15 heat (smallest of soldering irons) thus lending itself ad mirably to all electronic work.

But to unsolder a lead where two (2) 20 The method of using an improved solder connector or more wires go to the same lug is not always an easy of solid tinned bendable wire having a helical wound task.

This is especially true of the new transistors and printed circuits which re quire extreme care in soldering. It is with all this in mind that I devised my own solder connector to overcome these difficulties. end, designated as a “pig-tail,” which continues outward 25 ly from one endmost turn and terminates in an eye, for joining and splicing a wire by soldering the coil over the break in the wire, and embracing the selection of a short connector requiring minimal heat both in soldering on and thence moving along a wire, comprising the follow Fashioned from a continuous piece of wire, it is what ing steps: ?rst, the correct selection of coil connector for you might refer to as an improved connector.
