Abstract: An electrical connector system uses two electrical connector housings and two mating electrical connectors. The electrical connector housings are disposed on a support plate in an end to end relation and spaced apart by a distance smaller than twice the distance from the electrical connector housing to the fastener holding the connector to the connector housing. The fasteners are carried by and engaged with a retainer bar that further engages the connectors to pull the connectors into the connector housings and retain them in connection relationship, ensuring reliability of the connection.

Abstract: To enable a worker to be able to quickly and correctly verify that a slide-type cam member has moved into a closed position, making it possible for a housing of a mating connector to be moved into a completely engaged position, a resilient latch 40 member, which extends toward a housing 12 from an upper end of a side wall section 33 of a cam member 30, is located on the cam member 30. A latch section 50, which has an aperture 54 that receives a protrusion 42 of the latch member 40, is located on an upper part of the housing 12. As the cam member 30 is moved from a first position to a closed position, the latch member 40 is depressed downward as a result of the protrusion 42 moving along a second surface 55 of the latch section 50. When the cam member 30 has moved into the closed position, the protrusion 42 is received by the aperture 54 and, by virtue of the interrelationship, the latch member 40 resiles to its original shape.

Abstract: An edge connector for a plurality of daughter boards has a plurality of adjacent board-receiving openings which are configured to receive the daughter boards first in a common linear insertion direction at respective upstream positions and then in a common pivoting insertion direction to respective downstream positions. A plurality of latch members are operable to retain the daughter boards in their respective downstream positions. The latch members are also releasable to allow reverse pivoting of the daughter boards. The latch members are configured so that releasing the latch members associated with a relatively downstream one of the openings operates to release the latch members associated with relatively upstream ones of the openings, thereby preventing collisions between adjacent ones of the daughter boards.

Abstract: An electrical connector comprises a housing and IDC terminals having IDC contact sections. The IDC contact section comprises a large wire receiving slot extending into a narrower IDC slot for connection to conducting strands of a insulated conducting wire. The wires are inserted longitudinally into wire receiving cavities extending from a rear face of the connector, whereby the cavities are bent such that they traverse obliquely the terminals, thereby causing the wire to pass through the wire receiving slot of the terminal, aligned with the cavity. The wire is inserted until it abuts a stop and, the terminal can then be further inserted into the housing such that the wire is stuffed into the IDC slot for connection therewith. This design advantageously benefits from IDC technology whilst also providing a very compact wire-to-wire spacing. Additionally, the housing and terminals are relatively simple and cost-effective to manufacture.

Abstract: An electrical pin 230 has an elongate body which is receivable in a complementary socket of an existing electrical outlet, while two electrically conductive pins on the same plug are simultaneously receivable in respective sockets for establishing a power supply path for an electrical appliance. A resilient deformable ring 238 is held captive by the body of the pin 230. Two metal spheres 234 bearing respectively against an inner peripheral region of the ring 238 lie in a transverse passage 233 extending through the body of the pin 230. A screw 236 lying in a threaded passage 231 intersecting the transverse passage 233 bears against the spheres 234. In use the screw 236 urges the spheres radially outwardly, thereby expanding the ring 238 until it bears frictionally against an adjacent portion of an associated electrical socket. The pin 230 is preferably mounted in an insulating body (not shown) having a switch cover 38 projecting from the body in lateral relationship to the pin.
