Abstract

The present invention relates to a connector for electrically interconnecting two devices such as printed circuit boards, a printed circuit board and active device substrate and so forth. More particularly, the connector includes a contact element formed with three elongated beams extending between and connecting contact surfaces at each end and which buckle under compression to provide spring forces.

Claims

1. A connector for being positioned between and electrically interconnecting two devices having conductive traces such as printed circuit boards, comprising:

a. a housing of insulating material having a plurality of vertical passages therethrough with each passage having three longitudinally extending recesses spaced around the circumference thereof; and

b. a plurality of contact elements having a pair of spaced apart collars with three circumferentially spaced, elongated beams attached to and extending there between, each beam being formed to bend out laterally with a reversion point thereon being at the axial center of the element, and further having a contact surface attached to each collar and extending axially away therefrom, said contact elements being positioned in the passages with the contact surfaces extending outwardly therefrom and with each beam being in alignment with and adapted to be buckled into a recess by a compressive force which may be applied against the contact surfaces.

2. The connector of claim 1 wherein the contact element further includes support members which are attached to the collars and extend inwardly of the collars and under the contact surfaces for support thereof.
