Connector for connecting boards

Claim 1

A connector for electrically interconnecting a base printed-circuit board and a companion printed-circuit board in substantially perpendicular relation to each other, comprising: (a) a connector housing having an insertion slot opening at the top thereof for receiving the companion printed-circuit board therein, a plurality of grooves defined in a bottom of the connector housing in a direction normal to said insertion slot, and a plurality of pin attachment holes disposed between said grooves and said insertion slot; (b) a pair of guides mounted on opposite ends of said connector housing for loosely fitting engagement in positional adjustment holes defined in the base printed-circuit board; and (c) a plurality of contact pins each having bent portions, and first and second leg portions intersecting at said bent portions at an angle slightly greater than 90°, pivotally held in respective one of said pin attachment holes in the vicinity of said bent portions of the contact pin, said contact pins having ends positionable respectively in said grooves and opposite end extending into said insertion slot, whereby when said connector housing is attached to said base printed-circuit board and said companion printed-circuit board is inserted into said insertion slot, said contact pins are pressed against circuit patterns on said printed-circuit boards respectively at the ends of said contact pins.
