Electrical wiring devices that incorporate clamp-type wire terminal connections are described. The electrical wiring devices include for example, single and duplex blade-type electrical receptacles, blade-type locking electrical receptacles, single or multi-pole electrical switches, combination switches and blade-type receptacles, blade-type plugs for electrical cords and blade-type connectors for electrical cords. The electrical wiring devices include a plurality of contact assemblies. Each contact assembly includes a wire terminal and a plunger.

A core wire connecting body to be connected to a core wire in an electric wire includes: a bottom, a pair of cantilevered side walls that are disposed facing each other with a space therebetween; and a plurality of pairs of press contact bodies that are disposed facing each other with a space between the pair of side walls, and that cut the coating of the electric wire inserted from an opening, and make press contact with the strands. For the pairs of press contact bodies, compared to a distance between the press contact bodies that is a pair at the farthest section that is farthest from an end part of the electric wire, a distance between the press contact bodies that is a pair closer to the end part of the electric wire than the pair at the farthest section are, is smaller.

A coupling (1) comprising: a first part (2) sized and shaped to fit through an orifice in a surface and having a mounting surface (5) for abutting against the surface, and comprising a body having a through bore (7); and a first connector part (13) having a termination (15) for at least one conductor, and a connection member (16) for each termination (15); and a second part (3) in threaded engagement with the first part (2), the second part comprising a body having a through bore (10) in communication with the through bore (7) of the first part (2); a second connector part (14) having a connection member (17) complementary to each connection member (16) of the first connector part (13) so that the connection members (16, 17) of the first (13) and second (14) connector parts can engage each other and a termination (19) for a conductor for each connection member (16) of the second connector part (3).

A poke-in terminal includes a main body, a tab terminal socket at a mating end, and a wire socket at a terminating end. The tab terminal socket includes walls forming a tab terminal receptacle configured to receive a tab terminal. Upper and lower beam contacts extend into the tab terminal receptacle to interface with the tab terminal. The wire socket includes walls forming a wire receptacle configured to receive a wire. Poke-in retention beams extend into the wire receptacle to interface with the wire when poked into the wire socket. The wire socket includes a wire release element configured to be actuated to release the poke-in retention beams from the wire.

A connector system includes a barrel and a lug connector arranged at an end of the barrel. The lug connector has a first contact and a second contact separated by a clearance. A substrate is arranged within the clearance and is electrically and mechanically coupled to the lug connector over an electrical conduction surface area. The electrical conduction surface area extends over a portion of both the first contact and the second contact.

The present invention discloses a connecting wire, which comprises an electric wire and a wire joint connected to the electric wire; further comprises a connecting piece arranged on the electric wire, the connecting piece can be simultaneously connected with at least two devices. Through the setting of the connecting piece, a plurality of devices can be connected simultaneously, without additional temporary processing of the connecting wire, avoiding excessive contact between the lead of the connecting wire and the outside, and reducing the interference of external signals on the signal transmission of the connecting wire, so that the ECG monitoring analyzer can monitor the intracavitary ECG and electrode impedance changes in a timely and accurate manner, to ensure that the electrode lead can be screwed into the patient's heart safely and accurately and the surgery can be completed better and more safely.

A connector includes a housing to be assembled to a wall portion of a box-shaped body, a bus bar having a fastened portion that is disposed inside the wall portion and is to be connected to a terminal fitting by fastening using a bolt, a nut meshing with the bolt to fasten the fastened portion and the terminal fitting together, and a cover attached to the housing with a gap between the cover and the fastened portion into which the terminal fitting is capable of being inserted and covering the fastened portion the nut.

A connector includes a resin housing to be assembled to a wall portion of a box-shaped body, a bus bar held by the housing and having a fastened portion that is disposed inside the wall portion and is to be connected to a terminal fitting by fastening using a bolt, and a nut held by the housing with a gap between the nut and the fastened portion, the gap allowing insertion of the terminal fitting and engaged with the bolt to fasten the fastened portion and the terminal fitting inserted into the gap together. In the bus bar, a recessed portion recessed such that the bus bar is cut off is provided inside the wall portion. The recessed is exposed to an outside of the housing without being covered with a resin constituting the housing.

A modular power distribution terminal includes an outer housing containing a chamber and a bottom opening. The outer housing includes a top wall, a pair of spaced end walls and a pair of spaced parallel side walls having first fasteners. At least one module slice is arranged in the outer housing chamber and includes a slice housing including a pair of spaced parallel side walls having first fasteners configured for fastening with the first fasteners of one of the outer housing side walls and a current bar connected with and extending along a length of the slice housing. An input screw connection terminal and at least two output push-in connection terminals are connected with the current bar.
