Abstract

An arrangement for interconnecting a pair of hybrid integrated circuit boards mounted by means of pins in an upstanding position on a horizontally extending base circuit board in closely spaced, substantially parallel relationship, each of the hybrid circuit boards being provided with a row of contact terminals extending along the upper edge thereof together with a secondary printed circuit board having a row of downwardly directed, spring-like contact elements mounted along each side edge, the contact elements beng spaced so as to correspond with the contact terminals on the hybrid boards and with oppositely disposed contact elements being interconnected by a conductor whereby the secondary board may be detachably mounted in a horizontally extending position across the upper edges of the hybrid boards with the contact elements in each row in circuit making engagement with the adjacent contact terminals on the underlying hybrid boards thereby interconnecting the printed circuits of the hybrid boards.

Claims

1. A circuit board mounting arrangement comprising, in combination:

a base integrated circuit board having a printed circuit and a plurality of apertures for accommodating connector pins;

a pair of hybrid integrated circuit boards each having a lower edge and an upper edge and a printed circuit thereon;

a plurality of connector pins arranged at predetermined intervals on the lower edge of each of said pair of hybrid circuit boards, inserted into said base circuit board apertures, and mounting said pair of hybrid circuit boards in adjacent relationship on said base circuit board in an upstanding position on said base circuit board;

contact means positioned on the upper edge of each of said hybrid circuit boards and connected to the printed circuit on the respective hybrid circuit board, said contact means on said hybrid circuit boards comprising a plurality of contact terminals arranged in spaced relation on the upper edge of each of said pair of hybrid circuit boards;

a secondary integrated circuit board having a printed circuit and pair of side edges; and

contact means on said secondary circuit board adjacent each of said side edges in releasable engagement with said contact means on the upper edges of said hybrid circuit boards, said contact means on said secondary circuit board comprising a plurality of downwardly extending pairs of spring fingers for releasably accommodating one of said contact terminals on an associated hybrid circuit board, whereby said secondary circuit board and said hybrid circuit boards are held together in an operative position to interconnect the printed circuits on each of said pair of hybrid circuit boards.

2. A circuit board mounting arrangement in accordance with claim 1 including gripping means on said secondary circuit board for manually releasing said secondary circuit board from said operative position on said hybrid circuit boards.

3. A circuit board mounting arrangement in accordance with claim 2 wherein said gripping means comprises a string loop.

4. An interconnected circuit board arrangement comprising, in combination:

a pair of integrated circuit boards each having a printed circuit thereon and arranged in spaced-apart, parallel relationship;

a substantially planar printed circuit board having a pair of side edges;

contact means on said planar printed circuit board adjacent each of said side edges releasably engaging the upper edges of said pair of integrated circuit boards, said contact means comprising downwardly extending pairs of spring fingers arranged at predetermined intervals on each of said planar printed circuit board side edges for releasably engaging with printed circuits on an associated one of said pair of integrated circuit boards; and

said planar printed circuit board having a printed circuit thereon connected to said contact means for interconnecting the printed circuits on said pair of integrated circuit boards.

5. The circuit board arrangement of claim 4 wherein said planar circuit board includes gripping means for manually releasing said planar circuit board from engagement with said associated pair of integrated circuit boards.
