摘要： An overhead wiring system for use in the suspended ceiling of a clean room includes a generally rectangular housing with closed top, side and end walls and a substantially open bottom. A plurality of movable panels are provided in the bottom to close the bottom wall, one or more of the panels having openings through which a power cord can pass. A barrier within the housing divides its interior into a wiring chamber and a power cord chamber, the wiring chamber having a terminal strip connectable with wires from an external conduit. A power cord is connected to the terminal strip, through the barrier and through one of the panels with a stress-relieving cord grip in each of the pass-through locations. The housing is supporting so as to be substantially coplanar with a suspended ceiling and without exerting stress on the ceiling.

摘要： A pin and sleeve receptacle is mountable in a wall box recessed in a wall opening of a building with wires extending into the box from an in-wall wiring passage. The receptacle has a tubular electrically non-conductive shell closed at one end, the other end being open and a flange with fastener openings at the open end of the shell. A cylindrical inner body has an outer diameter smaller than the first inner diameter, the inner body having female connector sleeves for receiving electrically conductive pins of a mating plug. The inner body is mounted within the shell with an annular gap surrounding the inner body for receiving the shroud of the pin-and-sleeve plug. The opening at one end face the same direction as the open end of the shell to receive the pins of the plug. Apertures in the shell admit wires from the box for connection to the electrically conductive female connectors. An adapter plate has a central opening to receive the shell, holes to receive fasteners extending through the fastener openings in the flange and holes to permit passage of fasteners for mounting the plate across the opening of the recessed wall box. A cover plate has a central opening surrounding the open end of the shroud, openings for passage of fasteners for attaching the cover plate to the adapter plate with the flange in between, and sloping side edges for abutting the wall surrounding the box to form a minimally protruding assembly. A right-angle plug having pin connectors to mate with the receptacle to form a connector assembly with minimum protrusion from the wall is disclosed.

摘要： A universal AC/DC electrical connector for selectively coupling either a mating direct electrical current (DC) electrical connector or a mating alternating electrical current (AC) electrical connector to selectively receive both direct electrical current (DC) and alternating electrical current (AC) therein. The AC/DC electrical connector has a pair of direct current contacts, a pair of alternating current contacts, and a ground contact. When DC electrical connector is coupled to the AC/DC electrical connector, the direct current contacts and the ground contact electrically engage corresponding electrical contacts of the DC electrical connector, while the alternating current contacts of the AC/DC electrical connector remains uncoupled, i.e., alternating current connects of the AC/DC electrical connector does not electrically engage the contacts of the DC electrical connector. When AC electrical connector is coupled to the AC/DC electrical connector, the alternating current contacts and the ground contacts of the AC/DC electrical connector engage corresponding electrical contacts of the AC electrical connector. The AC/DC electrical connector can also be provided with a sensor in the form of a pilot contact or reed switches for determining whether direct electrical current or alternating electrical current is being supplied thereto.
