Abstract: A connector housing has a body portion and a hood portion. An insertion detecting member for terminal lugs is movable from provisional locking position to full locking position inside the hood portion. A resilient, terminal-lug locking piece extends in each terminal accommodating cavity in the housing body portion to form a displacement permitting space on a side opposite a side where a terminal lug is inserted.

Abstract: An electrical connector including an outer shell, and an integral rotatable cam shell positioned over the outer shell. The cam shell has at least one switch actuating cam extending radially from an outer surface thereof. Upon mating of the connector with a mating connector assembly, the cam shell is rotated to cause the cam to contact a switch and thereby change the switch from an open state wherein current flow through the connector is interrupted to a closed state wherein current is allowed to flow through the connector and the mating connector. Preferably, the connector further includes a spring positioned between the outer shell and the cam shell. The spring biases the cam shell against the outer shell axially in a direction away from the mating connector.

Abstract: A socket connects electronic components such as integrated circuit modules with arrays of solder balls or columns, lands, pads of similar contacts to other components, typically substrates such as printed circuit boards. The socket has a polarization post and locator posts that extend through polarization and locator holes in the substrate and in a registration sheet that locates the module with respect to the substrate. The heads of the posts, which are all substantially the same size, extend through arcuate slots in a cam ring. Each of the slots has an inclined ramp that engages the heads of the post. When the cam ring is turned, the heads of the posts ride up the ramps, moving the cam ring towards the substrate and compressing a wave spring that presses against a pressure plate.

Each of the plug and receptacle connector halves include respective dual plug and receptacle housings spaced apart from each other in a substantially parallel relationship. The dual connector housings of the plug and receptacle connector halves are evenly spaced apart by bridging pieces which extend between the connector housings to connect them together. The bridging pieces may either be integrally formed with the connector housings or they may be separately formed from the connector housings and include engagement members which engage the connector housings. The bridging pieces have power terminals disposed therein so that the connector assembly effects a connection not only between signal circuits of the circuit boards, but also between power circuits.
