Abstract: A safety cap for an electrical outlet having an adhesive section can be attached to a standard outlet cover. Alternately an outlet cover including two slidable plates including a spring or spring groove can be used to prevent access to the outlet by a child. An elongated member on one plate is used to contact a spring on the other plate. Alternately, the elongated member can fit into a spring groove to bias the plates apart into the closed position. Locking pins can be used to lock the plates onto an aperture at the base of a plug's power prong. Additionally, a recess around each electrical outlet can mate with a respective lip of a plug to provide an interlocking interface between the plug and outlet cover to prevent a child from being able to insert a metal object between the plug and the face-plate.

Abstract: A water-resistant electrical connector has a flow-down space S, through which water passes, formed between the outside surface of female terminal housings 30 and the inside of a male hood 12. Water which penetrates inside the male hood 12 from the end thereof passes through a flow-down space S to exit apertures 20, 37. Neighboring terminals are separated by hollow partition walls 11, 31. Partition walls 18 may project from the male connector and pass between adjacent female terminal housings to improve electrical isolation.

Abstract: An electrical connector is formed with a plurality of cavities in an ordered way in a housing. A retainer is fitted to the housing to cover the front faces of the cavities. The retainer doubly stops the female terminals by means of deformation regulating members provided therein, each of which enters a recessed portion of a respective lance, thereby regulating its deformation. The lances are associated with the cavities. The front face plate of the retainer has apertures formed thereon that align with the terminal insertion apertures located on the front face of the cavities. Ribs are formed between the apertures and project outwards, partitioning the apertures. Grooves that fit with the ribs are formed on the insertion face of a complementary connector. The creeping distance between the adjacent cavities is increased due to the provision of the ribs.

Abstract: A power connector comprises a plug mechanism and a socket mechanism. The plug mechanism is provided with a plurality of insulating tubes designed to enclose and arranged to be spaced around respective pinning mechanism. The socket mechanism of the connector is provided with corresponding holes for the tubes, tubular conductors for the pinning mechanism, and a housing element for partially receiving the plug mechanism, whereby when the pinning means are inserted into the holes, sparks, in case there are, will be kept apart from a person' hand by both the insulating tubes and the housing element.

Abstract: A mating electrical safety plug and receptacle. The plug includes a set of non-conductive tubular prongs, each of which shrouds a conductive element. The ends of each prong are open to receive a corresponding central post of the receptacle. The plug may include a ground prong. The receptacle is provided with a set of openings, each opening adapted to receive a corresponding prong. Each opening has a central post concentrically disposed, thus producing an annular cavity for the receipt of a tubular prong. Each central post includes a recess having a conductive element disposed therein. The receptacle may also be provided with a ground opening to accommodate a plug with a ground prong. The conductive element recessed within each central post engages with a respective conductive element shrouded by a corresponding prong. These mating conductive elements engage only when the plug is fully connected.

Abstract: A discharge lamp connector assembly comprises: a male connector having at least two male terminals, the male connector serving as a base of the discharge lamp, the male connector comprising a discharge preventing partition insulator projecting from substantially the center of a region between the male terminals; a female connector engageable with the male connector for securely retaining at least two female terminals which are engageable with the male terminals, the female connector comprising: a housing having spaced partitions which define a comportment for accommodating therein the female terminal, and a holder fitting over the housing by an elastic engagement whereby securely retaining the female terminals, the holder having slits for inserting the male terminals, the holder comprising means engageable with the region between the partitions defining the compartments of the having for receiving the partition insulator of the male connector.

Abstract: A connector comprising a housing having terminal insertion chambers in a jacket body, a terminal connecting shaft which is rotatably mounted between the terminal insertion chambers and so mounted through as to be operable from the outside of the jacket body, and electrically-conductive terminal connecting members disposed on the terminal connecting shaft in the terminal insertion chambers; and a plurality of connectors having terminals disposed in terminal holding chambers open to the outside. The terminals, in the terminal insertion chambers, face each other over the terminal connecting member when the connector is joined to the housing, and are connected to each other by rotating the terminal connecting shaft.

Abstract: A disconnectable electrical plug for use with a urological endoscope comprising a housing; a conductor; a connector; and an extension block keyed for insertion into a guide block of the endoscope. The extension block extends from the housing at a substantially right angle to the entry of the condutor into the housing and is insertable into the guide block in either a first or second position. A urological endoscope is provided comprising a guide block with an electrical plug channel with a first entry on a first lateral side and a second entry on a second lateral side such that an electrical plug can be connected directly to an electrode by mounting the plug in the channel in either the first or second side of the guide block.

Abstract: Multicontact electrical connector comprises a connector housing which has one part that is movable in a perpendicular direction to the housing axis. The terminal receiving cavities extend through the movable part and through the relatively fixed part. When the movable part is in one position, the terminals can be inserted into the cavities. When the movable part is moved to another position, a shoulder is formed in each cavity which prevents removal of the terminals from the cavities. The two parts are each plastic moldings and can be assembled to each other in a simple assembly operation.
