An actuation device which comprises the clamping spring is provided. Between the first limb and the second limb of the clamping spring, which is in the form of a tension spring, is arranged an insert device which provides a counter-bearing for a tool when the actuation device is actuated.

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 terminal strip having an insulating material housing that has a latching foot for latching onto a mounting rail and has a width less than the length and height, and conductor connections in the insulating material housing that are arranged next to one another in pairs. The insulating material housing is in two parts and has a base housing and a lower housing. The base housing has, in a first connection region, a pair of conductor connections that are electrically conductively connected to one another. In a second connection region, the base housing has a cutout that is laterally bounded by the insulating material of the second connection region. The lower housing can be inserted into the cutout. The lower housing has a conductor connection that is electrically insulated from an adjacent conductor connection that is arranged in the second connection region, in the base housing.

An electric apparatus comprises a casing formed of an electrically insulating material and at least one connection terminal mounted in the casing and intended to establish and maintain a contact between an electrical conductor inserted in the connection terminal and an electrical link bar mounted in the casing to ensure an electrical connection between the electrical link bar and the electrical conductor. The connection terminal is of the push-in type and comprises a contact spring configured so that the contact between the electrical conductor and the electrical link bar results from a force insertion of the electrical conductor in opposition to the action of the contact spring and is automatically maintained by the contact spring after insertion of the electrical conductor. The casing comprises a peripheral wall and a cover configured to be assembled together along a mounting direction substantially parallel to the direction in which the electrical conductor is inserted in the connection terminal.

An electrical apparatus such as an electrical contactor or a terminal block, comprises a casing made of an electrically insulating material, a conductive bar mounted in the casing and at least one push-in type connection terminal. The terminal comprises a contact spring having an elastic portion undergoing an elastic deformation under the action of an external force applied on the contact spring either by an electrical conductor during its insertion at a first aperture of the casing so as to place the electrical conductor in a contact position located between the contact spring and the conductive bar in order to establish an electrical connection between the electrical conductor and the conductive bar, or by a tool inserted into a second aperture of the casing so as to open the contact spring and release the electrical conductor in order to remove it out of its contact position. The electrical apparatus comprises a support clip independent of the casing and of the conductive bar. The clip comprises fastening elements allowing mounting of the support clip on the contact spring and delimits a bearing face against which the contact spring bears during the deformation of its elastic portion under the action of the external force in order to impose the manner in which the elastic portion spatially deforms and against which the contact spring abuts in its maximum deformation state in order to limit the elastic deformation of the elastic portion of the contact spring below a predetermined value regardless of the intensity of the external force.

An elastic-clip junction box structure has multidirectional wire insertion effect and holds the wires quickly. The junction box structure includes a case body and at least one conductive clip disposed in the case body. The case body is formed with a first-direction wire socket and a second-direction wire socket with different insertion directions. The conductive clip has a first-direction clip mouth in communication with the first-direction wire socket and a second-direction clip mouth in communication with the second-direction wire socket. In use, the wire can be selectively inserted into the first-direction wire socket or the second-direction wire socket. Alternatively, wires can be respectively inserted into both the first-direction wire socket and second-direction wire socket. Accordingly, wires can be selectively inserted into the elastic-clip junction box structure in multiple directions and quickly and securely held by the first-direction clip mouth and second-direction clip mouth or released therefrom.

A wire connection terminal structure includes a leaf spring, a conductive plate and a fixing frame framing and connecting with the leaf spring and the conductive plate. The conductive plate is formed with a base section assembled with the fixing frame. The leaf spring is formed with an elastic swingable holding section extending to a position in contact with the base section. The holding section and the base section define therebetween an elastic holding mouth. An external electrical wire can be plugged into the holding mouth and held between the holding section and the base section and electrically connected with the conductive plate. The conductive plate and the fixing frame are two separate components so that the conductive plate is solely made of a high-conductivity material, while the fixing frame is made of a material with higher structural rigidity.

A lead-through terminal includes a terminal housing to be held on a wall of an electrical installation, and a wall feedthrough and a pivotable actuation device being provided on the terminal housing. The actuation device is pivotable at least between a contact position and an open position to clamp a conductor at a conductor receptacle in the contact position and to release or hold the conductor at the conductor receptacle in the open position. A gap that exists between the actuation device and the wall feedthrough when the actuation device pivots between the open position and the contact position is closed at least in the contact position.

A screwless terminal block allows easy insertion and removal of a wire. A housing (2) includes a fixture insertion opening (23) through which a rod-like fixture (6) is inserted to come in contact with a contact pressure spring (4) and deform the spring (4) away from a wire (5). When the fixture (6) is inserted through the fixture insertion opening (23), an acute angle of 45° or less is formed by an axis of the fixture (6) and a straight line connecting a contact point A between the housing (2) and a part of the fixture (6) adjacent to the wire insertion opening (24) and a contact point B between the housing (2) and a part of the fixture (6) adjacent to the spring (4) at a cross-section taken along a plane including the axis of the fixture (6) and parallel to a pressing direction of the spring (4).

A wire connection device includes a housing, a conductor, and a lever. The conductor is located inside the housing and has a leaf spring, a conductive member and a push-back block, and the lever is provided with a push-back notch and an actuating cam, and the lever is movably assembled in the housing so that the lever may swing against the housing so that the leaf spring is squeezed by the lever for generating a deformation. When the lever swings to an actuate position, the touch surface of the cam that touch the conductor will be changed so that the lever can be moved in a straight line against the housing simultaneously. Therefore, the push-back block can be inserted into the inside of the push-back notch. In this way, when the push-back block is positioned inside the push-back notch, the lever is kept stay so that the leaf spring is kept in a state of deformation by the lever, and the wire can insert into the wire connection device without push the leaf spring, so that the wire connection device won't be damaged easily.
