A terminal block includes an insulative body, a conductive member, an elastic sheet and a pressing member. The insulative body has a receiving room therein and is formed with a pressing hole and a wire hole, which separately communicate with the receiving room. The conductive member is received in the receiving room and has a seat and a contact portion tilted up from the seat. The elastic sheet is received in the receiving room. An end of the elastic sheet is in contact with the conductive member. The pressing member is disposed in the pressing hole and capable of moving toward the receiving room to push another end of the elastic member. The pressing member has a placement slot. Each of two sides of the placement slot has a blocking wall.

A circuit breaker housing for holding a switching device unit and a number of connection contacts for a connection line and/or a busbar. The housing has a first housing part and a second housing part. In the joined, assembled state, the housing parts form a front side and a rear side opposite said front side and at least one connection side and end faces located opposite one another. A holding chamber for a connection module having one of the connection contacts is provided on the front side and/or on at least one of the connection sides.

Disclosed is a busbar tapping clamp (10) comprising a clamping member (16) that can be attached to a busbar (12) like a G-clamp, and sprung means (34) for bringing a conductor (32), which extends to the busbar tapping clamp (10), into electroconductive contact with the clamping member (16).

A problem addressed by embodiments of the invention disclosed herein consists in devising a connection device in which field terminations can be released also in the installed state, i.e., the electrical conductors can be manually disconnected using a simple tool even if the insulating body is already installed in an attachment housing. To this end, an actuator is proposed which has an inclined engagement portion with an adjoining engagement edge and engagement step by which the actuator can be lifted out of the insulating body, also from the cable connection side, with a slotted screwdriver in a single lifting movement.

The invention relates to an electrical connection system (7) for an electrical device, such as an electrical terminal block, said electrical connection system (7) comprising: a conductive bar (21) including an electrical contact region (45) arranged to cooperate with a conductive portion (13) of an electrical conductor (13) in a connected position, and an engagement zone (35) arranged to engage with a portion (15) of a support rail (15) in an engaged position; a leaf spring (23); and a retaining device (49) arranged to retain the support rail (15) in the engaged position, the conductive bar (21) consisting of a conductive strip.

A connector comprises a connector module including an insulation body in which a chamber and a wire hole are formed, a contact received in the chamber, and an elastic clip disposed in the chamber. The elastic clip is adapted to press a conductor of a wire inserted into the chamber through the wire hole against the contact. The conductor of the wire electrically contacts the contact.

A terminal block includes an insulative body, a conductive member, an elastic sheet and a pressing member. The insulative body has a receiving room therein and is formed with a pressing hole and a wire hole, which separately communicate with the receiving room. The conductive member is received in the receiving room and has a seat and a contact portion tilted up from the seat. The elastic sheet is received in the receiving room. An end of the elastic sheet is in contact with the conductive member. The pressing member is disposed in the pressing hole and capable of moving toward the receiving room to push another end of the elastic member. The pressing member has a placement slot. Each of two sides of the placement slot has a blocking wall.

The present disclosure discloses an electrical connection device and a plug assembly, the electrical connection device comprises a receptacle assembly and a plug assembly. The receptacle assembly comprises a cage and a connector. The plug assembly comprises an outer housing and a communication module provided in the outer housing. The outer housing has a main body which can be inserted into the cage along the mating direction to be mated with the connector. The receptacle assembly is provided with at least one guide groove extending along the mating direction, and the outer housing of the plug assembly is provided with at least one guide block protruding from the main body to correspond to the at least one guide groove, when the plug assembly is mated with the receptacle assembly, the at least one guide block enters into the corresponding guide groove along the mating direction.

A terminal block includes a housing having insulation properties, the housing having a holding portion provided in the housing and a terminal connection surface, a first opening portion through which a conductor portion of an electric wire can be inserted and pulled out and a second opening portion that is adjacent to the first opening portion and through which a jig can be inserted and pulled out being arranged in series in an array direction on the terminal connection surface and each communicating with the holding portion, and an opening surface being provided on a side of the holding portion in a width direction intersecting the array direction and a direction intersecting the terminal connection surface, and a terminal electrode portion and a leaf spring portion arranged in the holding portion. The housing is provided with a first movement restriction portion that restricts the movement of the moveable portion of the leaf spring portion in the width direction.

A terminal block includes a display-use moveable member which has a main body portion that can reciprocate in the direction intersecting a terminal connection surface and a contact moveable portion that extends along a guide surface, has a first end portion in an extension direction that is disposed so as to come into contact with a conductor portion in an electric wire passage portion and move in a first direction away from the terminal connection surface, and has a second end portion in the extension direction that is connected to the main body portion, and moves in an array direction in response to movement of the first end portion in the first direction to move the main body portion in a second direction toward the terminal connection surface.
