A terminal block electrically relays inside and outside of a partition wall sealing a liquid. The terminal block includes a housing disposed so as to penetrate the partition wall, a bus bar inserted into the housing, a seal member attached to the housing so as to seal a gap between the bus bar and the housing, and a holder assembled to the housing outside the partition wall with respect to the seal member so as to prevent the seal member from coming off. The bus bar extends across the inside and outside of the partition wall through a first through hole of the housing, a seal hole of the seal member, and a second through hole of the holder. Durability of a material constituting the housing to the liquid is better than durability of a material constituting the holder to the liquid.

An apparatus for securing an electronic component to a DIN rail including an electronic component, a latching system positioned on an end of the electronic component adapted for attachment to the DIN rail, wherein the latching system is made of a plastic material, wherein the DIN rail has a flat upper surface with two legs extending downwardly from, and perpendicular to, the flat upper surface, and a flange extends outwardly from each leg, wherein the latching system includes a recess, an upper surface above the recess having an angled slot positioned in the upper surface adapted to receive an upper flange of the DIN rail, and a lower surface below the recess adapted to have an end of a lower flange of the DIN rail positioned thereover.

A header power connector includes a header housing assembly including an outer housing having cavities that receive corresponding inner housings, which hold terminals for electrically connecting upper and lower busbars. The inner housings are movable relative to the outer housing to accommodate misalignment of the corresponding upper and lower busbars. The terminals are movable in the terminal channels of the inner housings to accommodate misalignment of the corresponding upper and lower busbars.

A terminal block (1) with an elastic retracting fixation member, including an insulation base (10) having a cavity (13) and a cable insertion slot (14) communicating with the cavity (13), a cover member (20) covering the insulation base (10) and having a tool access hole (23), a conductive assembly (30) arranged in the cavity (13) and having a carrying member (32), and an elastic retracting fixation member (40) arranged corresponding to the tool access hole (23) and having an elastic element (41) and a fixation element (42), the elastic element (41) arranged between the fixation element (42) and the cover member (20), the fixation element (42) being operatively disengaged from the cover member (20) to attach to the carrying member (32) and retracting into the cover member (20) via a recovery force of the elastic element (41). Accordingly, it is able to prevent disengagement of the fixation member effectively.

A circuit interrupter adapted to be detachably connected to a rail system includes a housing having a notch disposed thereon adapted to receive a first leg of the rail system. An engagement member having a notch disposed therein adapted to receive a second leg of the rail system is slideably carried by the housing such that the notch in the engagement member is moveable in a first plane toward and away from the notch in the housing between an engaged position and a disengaged position. An actuation member is slideably carried by the housing and is moveable in a second plane, different than the first plane, between an actuated position and an unactuated position, movement of the actuation member in the second plane being translated into movement of the engagement member in the first plane.

An electrical component is provided, comprising at least one plug-in socket for receiving an accommodated component, in particular a relay or an optocoupler, in or on the electrical component, the accommodated component having first electrical contact elements on its underside, for being electrically connected to second electrical contact elements of the electrical component, and wherein in an active position of the accommodated component, the first electrical contact elements are electrically connected with the second electrical contact elements of the electrical component on the plug-in socket, and comprising a manipulation means, by means of which the accommodated component can be more easily plugged into the active position in the plug-in socket and/or pulled out thereof, wherein the manipulation means has a spacing portion, and wherein a free end of the spacing portion protrudes beyond the electrical component and/or beyond the accommodated component that is inserted in the plug-in socket in the active position.

A terminal block includes an insulative case, a supply-side conductive plate and a wire connecting module. The insulative case has two wire holes. The supply-side conductive plate is disposed in the insulative case. The wire connecting module is mounted on the supply-side conductive plate and includes a feed-side conductive plate, two insulative supports and two flexible clamping sheets. The feed-side conductive plate is electrically connected to the supply-side conductive plate and includes a first side wall and a second side wall opposite to each other. Each insulative support is arranged on the feed-side conductive plate. Each insulative support and the second side wall jointly form a clamping space. Each flexible clamping sheet is separately disposed on each insulative support. One end of each flexible clamping sheet is flexibly connected with the first side wall, and another end of each flexible clamping sheet is located in the clamping space.

The invention relates to an overvoltage protection arrangement for information and telecommunication technology, consisting of a housing with means formed on the housing base for mounting top-hat rails, overvoltage protection elements which can be found in the housing, electric connection means, and at least one circuit board as a wiring support for the overvoltage protection elements. When viewed laterally, the housing is designed approximately in the shape of a T standing on its head and has a beam-shaped main part with a protruding head part, wherein the electric connection means can be accessed and actuated via the upper face of the beam-shaped main part. A first and second circuit board are located on a respective inner face of the lateral walls of the housing in a mutually spaced manner, and the electric connection means in the form of electric connection terminals, connection sockets, and/or plugs for example are arranged in the spacing between the first and second circuit board such that first connection means can be accessed on the horizontal plane of the beam-shaped main part and second connection means can be accessed on the vertical plane of the beam-shaped main part. The flat shape of the circuit board corresponds to the T shape of the housing or approximates the shape of the housing.

A metal protective conductor connection element has a metal foot arrangement which has at least one first metal foot and at least one second metal foot for supporting on a support rail. The first metal foot has a first spring element with a contact region for forming a force-fitting connection of the first spring element of the first metal foot to the support rail and a second spring element with a securing region for forming a form-fitting connection of the second spring element of the first metal foot to the support rail. The second metal foot has a first spring element with a securing region for forming a form-fitting connection of the first spring element of the second metal foot to the support rail and a second spring element for forming a form-fitting connection of the second spring element of the second metal foot to the support rail.
