Abstract
Abstract A connector assembly is disclosed having both the capability of being mass terminated and for effecting zero insertion force mating with conductive holes of a printed circuit board or the like. The subject connector system includes a pair of identical housing members, each of which receives a plurality of terminals therein, and a pair of hermaphroditic cover members. Each housing member is an elongated member of insulative material having a mating face and a plurality of terminal receiving passages opening onto the mating face. The terminals each have a first end lying within the housing and capable of effecting mass termination of individual conductors by insulation displacing means and a second end extending from the mating face of the housing in resilient cantilever beam fashion. Each of the hermaphroditic/cover members encloses a respective one of the housing members to form a complete subassembly. Each subassembly is mated to a circuit board in a tilted condition with the resilient beams of the terminals extending into the conductive holes of the circuit board. The subassemblies are then rotated relative to each other to latch the cover members together while bringing the beams into contact with the side walls of the conductive holes thereby effecting contact therewith while securing the connector assembly in the printed circuit board.

Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
219 words
An electrical connector assembly comprising: a pair of identical elongated housing members of rigid insulative material each having a plurality of terminal passageways extending from a rear end through said housing members to open on a front mating face, each said passageway having a fully enclosed portion adjacent the mating face and an outwardly open channel shaped portion at the rear end remote from said mating face; a like plurality of terminals each mounted in a respective one of said passageways, each terminal having a forwardly directed cantilever beam extending from said mating face and an insulation displacing conductor engaging rear end portion lying in and accessible from said channel shaped portion; and a pair of hermaphroditic cover members each having means engaging a respective one of said housing members to form a subassembly, latching means detachably securing said cover members together, and mounting legs receivable in mounting apertures in a circuit board whereby said subassemblies are initially individually engaged with an angular orientation to a circuit board with the beams of the terminals extending into but not contacting conductive holes in the circuit board and the subassemblies rotated with respect to one another and the circuit board to bring said cover members into locking engagement while bringing the beams into engagement with the walls of said conductive holes.
Claim 2
Dependent Claim
219 words
An electrical connector assembly comprising: a pair of identical elongated housing members of rigid insulative material each having a plurality of terminal passageways extending from a rear end through said housing members to open on a front mating face, each said passageway having a fully enclosed portion adjacent the mating face and an outwardly open channel shaped portion at the rear end remote from said mating face; a like plurality of terminals each mounted in a respective one of said passageways, each terminal having a forwardly directed cantilever beam extending from said mating face and an insulation displacing conductor engaging rear end portion lying in and accessible from said channel shaped portion; and a pair of hermaphroditic cover members each having means engaging a respective one of said housing members to form a subassembly, latching means detachably securing said cover members together, and mounting legs receivable in mounting apertures in a circuit board whereby said subassemblies are initially individually engaged with an angular orientation to a circuit board with the beams of the terminals extending into but not contacting conductive holes in the circuit board and the subassemblies rotated with respect to one another and the circuit board to bring said cover members into locking engagement while bringing the beams into engagement with the walls of said conductive holes.
