Abstract

Fig. 1 shows a fastener for a printed-circuit card which is physically small, solderable and has a screw mounting. Further, it is capable of handling high currents and is inexpensive to manufacture. One of the methods of manufacture of the fastener may be by fabricating from sheet stock, through punching and roll forming to a final shape, including the threading. The material may be copper, brass, or any suitable, electrically conductive material.

Electrical Conductive Insert

Fig. 1 shows a fastener for a printed-circuit card which is physically small, solderable and has a screw mounting. Further, it is capable of handling high currents and is inexpensive to manufacture. One of the methods of manufacture of the fastener may be by fabricating from sheet stock, through punching and roll forming to a final shape, including the threading. The material may be copper, brass, or any suitable, electrically conductive material.

Once the fastener is manufactured, it may be attached to the printed-circuit board as illustrated in Fig. 2. The fastener 1, shaped as shown in Fig. 1, is inserted into a hole in a printed-circuit card 3. On the other side of card 3, a pan- head screw 5 is inserted into fastener 1. As screw 5 is turned down, the head of screw 5 causes flanges 7 of fastener 1 to fan-out. This fanning-out process results in fastener 1 being attached to printed-circuit card 3.
