Abstract

The figures show an assembly for terminating cable 1 of fine wires 3. Bare wires 3 span two printed circuit boards 5 having grooves 7 to receive and locate wires 3. Insulator 9 is brought down over all the wires, and clamping spring 11 is clamped over insulator 9. A relief member 13, having notched arms 15 which deform around and resiliently clamp into the sides of insulator 9, is attached over the body of cable 1. No soldering is employed. The completed assembly is shown from the side in Fig. 2. Board 5 has an inset 17 into which notch 19 on insulator 9 fits. Clamping spring 11 forces notch 19 into inset 17, thereby producing a locking action. Relief member 13 isolates forces on cable 1 from wires 3 in the assembly. Fig. 3 illustrates the fabrication of two boards 5.

Electrical Termination of Wire Cable

The figures show an assembly for terminating cable 1 of fine wires 3. Bare wires 3 span two printed circuit boards 5 having grooves 7 to receive and locate wires 3. Insulator 9 is brought down over all the wires, and clamping spring 11 is clamped over insulator 9. A relief member 13, having notched arms 15 which deform around and resiliently clamp into the sides of insulator 9, is attached over the body of cable 1. No soldering is employed. The completed assembly is shown from the side in Fig. 2. Board 5 has an inset 17 into which notch 19 on insulator 9 fits. Clamping spring 11 forces notch 19 into inset 17, thereby producing a locking action. Relief member 13 isolates forces on cable 1 from wires 3 in the assembly. Fig. 3 illustrates the fabrication of two boards 5. Holes 21 are drilled and plated in the center of a board 23 twice the desired size of a board 5. Board 23 is then cut along the center of holes 21. The two sides, after such finishing or processing as may be desired, each constitute a board 5. As shown in Fig. 1, two boards 5 simultaneously may be terminated. For clarity, only one terminating assembly is shown in Fig. 1. When cable 1 is terminated by an assembly as shown on each board 5, the wires 3 intermediate the two boards 5 are cut at each assembly and discarded. The cable 1 shown is suitable for use as electrodes in an electrical drive head. More generally, the ends of cable 1 opposite the terminating assem...
