A carrier rail housing comprises: a carrier rail receiving opening into which the holding legs of a carrier rail are insertable; a locking mechanism to secure the holding legs in a desired mounting position and comprising locking slides to interlock with the carrier rail housing in a locking position; a plug-in contact element arranged inside the carrier rail housing to face the carrier rail receiving opening; and a bus connector into which plug-in contacts of the plug-in contact element are insertable, the bus connector being connectable to a plug-in contact element of at least one additional carrier rail housing, wherein each of the locking slides comprises a first end that comprises a holding section that extends in sections into the carrier rail receiving opening in the locking position, so that the bus connector is secured between the holding sections of the locking slides and the plug-in contact element.

A DIN rail installing portion structure of an electrical appliance and a socket are provided. A back cover of a socket includes: a fitting groove, which is fitted to a DIN rail; and a claw portion, which is formed on a first side surface portion of both side surface portions of the fitting groove. A first edge portion of the DIN rail is clamped by the claw portion to hold the socket 1 on the DIN rail. The claw portion elastically presses a first edge portion of the DIN rail in a thickness direction. On the first edge portion side of the DIN rail, there is no claw of which a width of clamping the first edge portion in the thickness direction does not change.

Device for a busbar system, wherein a housing of the device comprises, on one housing side, electrical connection contacts which are configured in such a way that they are passable through feed-through openings of a contact protection baseplate module of the busbar system and are insertable into uniformly spaced contact openings located below the feed-through openings of busbar modules provided inside the baseplate module for producing a direct electrical and mechanical connection to the busbar modules.

A device for securing a communications or automation device to a top hat rail, wherein the device includes a base body, which can be connected to the communications or automation device on a front side, where at least one fixed first securing element that includes a groove or an undercut that can be engaged with an offset end of a first limb of a top hat rail is provided on a rear side of the base body, at least one second securing element provided on the rear side of the base element, which can be moved in the direction of the first securing element, is pretensioned in relation to the first securing element via a spring mechanism and includes a groove or an undercut that can be engaged with an offset end of a second limb of the top hat rail.

The invention relates to a locking mechanism (20, 22) for an electrical assembly (10); said locking mechanism (20, 22) comprises a buckle (20) that is hinged to the assembly (10) by means of a flexible buckle connecting part (30), and a buckle bracket (32) that is used for deflecting the buckle (20); limiting means (34, 35, 36, 37, 38) restrict a mobility of the buckle bracket (32) when the buckle (20) is deflected. An assembly (10) comprising a locking mechanism (20, 22) of said type is also disclosed.

A stackable module has a housing provided to receive an electric/electronic component, and a clamping device for attachment to a support rail, wherein the clamping device has two latching/gripping hooks, which are displaceable in mutually opposite directions between an open position and a fastening position, and a force deflection mechanism for adjusting the latching/gripping hooks between the open position and the fastening position, said mechanism being actuable by means of an actuating element and able to be subjected to an actuating force from an outer side. In this case, the latching/gripping hooks bound a free opening distance which, for release fastening to the support rail, is greater in the open position and smaller in the fastening position than a provided support rail extent. In this case, provision is made for the force deflection mechanism to have an actuating-element-side deflection profile and a hook-side displacement part, which has a deformation portion which is deformable by a displacement force in order to generate a hook-side displacement, wherein between the deflection profile and the deformation portion, a sliding contact is able to be formed, at which the deformation portion is able to be subjected to the displacement force via the deflection profile.

A rail fixing system comprises a rail fixing arrangement adapted to fix the rail fixing system to a profile rail, a system coupling arrangement adapted to fix the rail fixing system to another rail fixing system disposed adjacent to the rail fixing system on the profile rail, and an actuation device common to the rail fixing arrangement and the system coupling arrangement. The actuation device is connected to a first positive-locking connection element of the rail fixing arrangement and a second positive-locking connection element of the system coupling arrangement. The actuation device is supported on a resilient element and the first positive-locking connection element, the second positive-locking connection element, and the resilient element are arranged along a straight line that extends in an effective direction of the resilient element.

A housing includes a first wall and a second wall. The first wall and the second wall face each other in a first direction. A printed circuit board is accommodated in the housing with one surface of a substrate facing the first wall. The housing has a through hole. The through hole extends from an outer surface through an inner surface of the housing. The through hole is open in the inner surface of the housing along a second direction. The second direction is orthogonal to the first direction.

To enable an intuitive and inexpensive releasable fastening of a housing to a fastening rail, a fastening apparatus is provided for the releasable fastening of the housing to the fastening rail, comprising a single-part lever mechanism for latching and unlatching the housing to and from the fastening rail, wherein the lever mechanism comprises an actuation means that moves the lever mechanism into a latching position or into an unlatching position; a first lever arm that actuates a first hook provided in the housing in a first direction; and a second lever arm that actuates a second hook provided in the housing in a second direction, and wherein the first and second directions are opposite one another and the first and second lever arms are connected to one another via the actuation means such that a support section is formed that has a parabola-like form having two parallel limbs.

A railway termination shunt enclosure including one or more receptacles, each of the one or more receptacles being configured to receive a termination shunt. The enclosure also includes at least one mounting surface and a connector assembly rotatably attaching the one or more receptacles to one or more of the at least one mounting surface.
