Abstract

In compacted and miniaturized electronic circuits, it is often necessary to mount a number of circuit cards at right angles to a basic card. The circuits on the basic card are extended on pins over which multiple contacts on the smaller cards are positioned. A large amount of friction is created resisting the insertion force and in some instances damaging either contact or pin.

Circuit Card Connector

In compacted and miniaturized electronic circuits, it is often necessary to mount a number of circuit cards at right angles to a basic card. The circuits on the basic card are extended on pins over which multiple contacts on the smaller cards are positioned. A large amount of friction is created resisting the insertion force and in some instances damaging either contact or pin.

This connector reduces the insertion force needed. Spring contacts 10, shaped as shown, are soldered to the end lands of circuit card 11. The free end of the spring rides on cam surface 12 formed on housing 14. apertures 15 above the cam surfaces connect with opening 16. They are large enough to accommodate pins 17 of basic card 18. When card 11 is inserted in the housing, springs 10 ride over cam surface 20 and with the card fully seated the springs bear on surface 12.

In order to assist in positioning the housing over pins 17, a tool is used. The small ends of the housing are formed with key 21 on which arm 22 is locked. Arms 22 are provided with grooves 23 in which the card is free to slide. Bayonet slot 24 is formed near the top of each arm in each of which is positioned rod 25. Arm 26 formed of spring-metal is positioned on each of the rods and the arms are secured together between the rods to form finger 27. Finger 27 bears against the top of card 11. Pressure on areas 28 flexes the arms forcing finger 27 down to depress the card in housing 14. This slides spri...
