A terminal block structure includes an insulative base, a conductive terminal, a toggle member and an elastic clamping piece. The insulative base has a chamber, a wire hole and an opened trough communicating with the chamber. The wire hole and the opened trough are located on the same side of the insulative base. The conductive terminal is fixed in the chamber. The toggle member has a main body, a stem and a pressing portion extended from the main body. The main body has a pivoting portion pivotally connected to the insulative base. The stem projects to outside of the insulative base from the opened trough and is movable on a lateral side of the wire hole. The elastic clamping piece is disposed in the chamber. An end of the elastic clamping piece is pressed by the pressing portion to operably open or close the wire hole.

A spring-force terminal connection for connecting a conductor includes: a bus bar; a clamping spring by which the conductor to be connected is clamped against the bus bar when in a clamped state; a pivotably arranged actuation lever, the clamping spring being actuatable by a pivoting movement of the actuation lever; and a clamping cage, which forms a space for accommodating the conductor to be connected. The clamping spring includes a leaf spring and has a first end section forming a clamping region and a second end section opposite the first end section and forming a holding region. The clamping spring is fastened to the clamping cage by the second end section.

A device (1) for accommodating an electrical or electronic component (400), in particular a relay socket for accommodating a relay, comprises a base body (100) with a receptacle (110) for the component (400). The device (1) also comprises at least one pair (300) of connecting terminals connected to the two electronic connections, wherein the pair (300) of connecting terminals comprises a first connecting terminal (310) for a first connecting wire and a second connecting terminal (320) for a second connecting wire. The first connecting terminal (310) is spaced apart from the receptacle (110) by a first distance in a first direction and the second connecting terminal (320) is spaced apart from the receptacle (110) by a second distance in the first direction, wherein the first distance and the second distance are different.

In some examples, a contact module comprising housing, middle pole, wiring unit body, wherein the middle pole and the wiring unit are disposed in the housing; the middle pole moves up and down in the housing to realize the connection or disconnection between the middle pole and the wiring unit; the wiring unit body is disposed inside the housing, and the wiring unit body is provided therein with electrically conductive part for realizing the connection between conductor wire and the wiring unit body, and a pressing part for realizing the withdrawal of the conductor wire from the electrically conductive part provided in the wiring unit body, and the conductor wire connected into the electrically conductive part can be quickly pulled out by operating the pressing part wherein the housing is provided with conductor insertion port for the conductor wire to be inserted into the electrically conductive part.

A conductor connection terminal, having an insulating material housing, a busbar, a clamping spring and an operating lever which is pivotably received in the insulating material housing over a pivoting range and can be pivoted between an open position and a closed position, wherein the clamping spring has an operating arm which is deflected via a spring driver of the operating lever at least in the open position, characterized in that the operating lever is supported in the open position at a first and a second support point spaced from the first, and that the operating lever is pulled against the first and the second support point by a tensile force of the clamping spring acting on the spring driver from the operating arm.

A connection arrangement for connecting an electrical conductor includes: a busbar; a clamping spring by which the conductor to be connected is clamped in a clamping position of the clamping spring against the busbar; and an actuating element by which the clamping spring can be moved from the clamping position into an open position. A holding element is provided which, in the open position, engages with the actuating element to hold the actuating element in position. The holding element has a pressure surface. For moving the clamping spring from the open position into the clamping position, the pressure surface can be actuated by the conductor to be connected and the holding element can be disengaged from the actuating element by the actuation of the pressure surface.

Disclosed herein is a conductor connection clamp that includes a bus bar and a clamping spring, the clamping spring including a main portion for clamping an electrical conductor to the bus bar, the main portion and bus bar defining a clamping spring connection, and a spring member adjacent to the main portion and rigidly coupled to the main portion. The clamp further includes a housing defining a conductor insertion opening that leads to the clamping spring connection, and an operating lever configured to apply force to the spring member in order to deflect the main portion to open the clamping spring connection.
