Abstract

In making connection to edge connectors on circuit boards and the like, many times great stress is placed upon the circuit board causing cracking of the delicate foil circuit interconnections, bending of the contacts and misregistration, resulting in poor interconnection between the edge connector and the circuit board. This is especially true in high-density, closely-spaced circuit connectors. Accordingly, it is desirable to provide a connector which requires zero force for insertion and yet which will grasp the metallized contacts on the edge of the circuit board and make a good connection thereto, without placing undue strain on the circuit board.

Twin Contact Connector

In making connection to edge connectors on circuit boards and the like, many times great stress is placed upon the circuit board causing cracking of the delicate foil circuit interconnections, bending of the contacts and misregistration, resulting in poor interconnection between the edge connector and the circuit board. This is especially true in high-density, closely-spaced circuit connectors. Accordingly, it is desirable to provide a connector which requires zero force for insertion and yet which will grasp the metallized contacts on the edge of the circuit board and make a good connection thereto, without placing undue strain on the circuit board.

Referring to the drawing, printed circuit board 10 having metallized fingers or connectors 11 (one shown) extending inwardly from one edge of the circuit board and on opposite sides thereof, is illustrated as being positioned in a twin-contact connector 12, which is in the open position in Fig. 1 and in the closed position in Fig. 2. The twin-contact connector comprises a pair of leaf springs 15 which are cantilevered at one and 13 in a base 14. Each of the leaf springs has a lower and upper point connector 16 and 17, respectively. As illustrated in Fig. 1, the lower point connectors 16, when in the open position, are spaced from but more closely adjacent the metallized fingers 11 on the circuit board 10 than the uppermost contact points 17. Separate cams 18 are positioned on opposite sides of...
