Disclosed is an overstretch prevention mechanism for a clamping spring (3) of a clamping spring-type contact device, the overstretch prevention mechanism consisting of a stop (21, 11) of an actuator (2) on a bus bar (1).

An operable wire connector comprises an insulating housing (1), an operating handle (2) rotatably mounted inside the insulating housing (1), a transmitting piece (3), an electric conductor (4), an elastic clamping piece (5) with a fixed portion (51) connected to the electric conductor (4) and an elastic free portion (52) resisted by the transmitting piece (3), and a cover (6) assembled with the insulating housing (1); an adjustable gap is formed between the elastic free portion (52) and the electric conductor (4) for receiving a wire, and the gap will continuously be present due to the action of a rotation limiting portion (12). The operating handle (2) is pulled reversely, so that the wire comes into contact with the electric conductor (4); when the user pulls and turns up the operating handle (2) again, there is no need to continuously use force, and the wire will be take out easily.

A connector assembly comprises a first connector and a second connector. The first connector consists of a first monolithically formed conductive terminal adapted to be soldered onto a first circuit board. The second connector consists of a second monolithically formed conductive terminal adapted to be soldered onto a second circuit board. The first connector mates with the second connector to electrically connect the first circuit board to the second circuit board.

A conductor connection terminal having several spring force clamping connections, each of which has at least one clamping spring, which form a clamping point for clamping an electrical conductor with an associated busbar piece. The invention also relates to an electrical connector having at least one such conductor connection terminal.

A lead terminal that has a modular design, and that has at least one connection module and a plug-in module. The plug-in module being separate from the connection module.

Disclosed are a terminal block assembly (10) and its wiring wrench (2). The wiring wrench (2) includes a press rod (21) and a handle (22), and the press rod (21) has a pressing protruding arm (211) on a side and a stop portion (212) on the other side, and the handle (22) and the press rod (21) are connected by a pivoting structure (23), and the handle (22) has a clamping protruding arm (221) on a side and an elastic arm (222) on the other side, and the clamping protruding arm (221) and the pressing protruding arm (211) are configured to be opposite to each other, and the elastic arm (222) may selectively abut at the stop portion (212). Therefore, the wiring wrench (2) can be latched securely with the terminal block (1) to provide the effect of latching the terminal block (1) conveniently.

A connector assembly comprises a first connector and a second connector. The first connector consists of a first monolithically formed conductive terminal adapted to be soldered onto a first circuit board. The second connector consists of a second monolithically formed conductive terminal adapted to be soldered onto a second circuit board. The first connector mates with the second connector to electrically connect the first circuit board to the second circuit board.

A conductor connection terminal with a spring-loaded terminal connection for connecting an electrical conductor. The spring-loaded terminal connection has a clamping spring and an actuating mechanism for displacing at least one part of the clamping spring between an open position and a closed position.

The invention relates to a support profile rail element (1) comprising a longitudinal profile rail element (2) and a connection terminal (3). The connection terminal (3) has an insulating material housing (5) and a plurality of spring force clamping connections (6). Each of the spring force clamping connections has: a first conductor clamping point (61) for directly mechanically and electrically coupling at least one electric conductor (103) in a first conductor connection direction (L1) and a second conductor clamping point (62-64) which is electrically connected to the first conductor clamping point (61) of the same force clamping connection (6) in order to directly mechanically and electrically couple at least one external electric conductor for electrically connecting the support profile rail element (1).

An electrical connector includes a housing and a conductive contact assembly disposed in the housing. A first contact member of the contact assembly receives a blade contact of an electrical device. A second contact member receives an electrical wire through a push-in connection. The electrical connector is receivable by an aperture in a rear surface of the electrical device.
