Abstract: A connection terminal for connecting a conductor is formed as a direct plug-in terminal and includes a clamping spring arranged in a housing. The clamping spring includes a resilient clamping leg which can move into an open and locking position by pressing down an actuating device. The housing contains a conductor insertion channel for insertion of the conductor into a clamping point between the free end of the clamping leg and a busbar. The actuating device includes a pressing element and a pivoting element which interacts with the pressing element at least when the clamping point is being opened. At least one release device is provided for releasing the locking state of the clamping leg of the clamping spring. The release device is designed in such a way that the locking position can be released again by the action of the conductor on the release device when it is inserted, wherein the pivoting element acts on the pressing element and the pressing element acts on the clamping leg.

Abstract: A modular plug connector in a strip-shaped design can be plugged together with a corresponding mating plug connector such as a printed circuit board plug connector. The modular plug connector has a plurality of plug connector modules which are arranged alongside one another and are connected mechanically to one another using mechanical connectors to form the strip shape. The plug connector modules each have a module housing, at least one plugging surface with at least one plugging contact and preferably at least one conductor or solder terminal for connection to a printed circuit board. The plug connector has at least two plug connector modules of different designs and an adapter plug connector module is provided therebetween.

Abstract: A terminal strip is formed as a printed circuit board plug connector and has a strip-like housing composed of a plurality of terminal housings which are arranged alongside one another in an arranging direction X. The housings are mechanically connected to one another. The terminal housings each have a plugging face side on which they have at least one first plugging contact which can be plugged together with a corresponding plugging contact of a corresponding plug connector.

Abstract: A latching foot assembly for latching electrical components on a support rail includes first and second latching feet or members each including first and second resilient clamping portions between which the support rail is latched or grasped. A latching finger is integral with the first clamping portion of each latching foot. The first clamping portions of the latching feet are connected in interlocking fashion. The latching finger of the first clamping portion of the first latching foot has a support surface for supporting the support rail in a latched state. The support surface extends farther in the direction of the second clamping portion than a support surface for supporting the support rail in the latched state of the latching finger of the first clamping portion of the at least one second latching foot.

Abstract: An apparatus for distributing current in a low-voltage system includes a plurality of disk-shaped modules that can be arranged adjacent to each other in a row and mounted or locked on a carrier rail. At least one supply module, at least one fuse module, and at least one distributing module are provided. The modules have at least one cross connector for a positive potential and at least one cross connector for a negative potential. The fuse module and the distributing module also have at least one additional cross connector for a potential that is protected by the fuse module.

Abstract: A ground conductor includes a conductor body formed from a sheet of conductive metal material of a given thickness, the conductor body having a horizontal base portion, and a pair of downwardly extending vertical leg portions that contain opposed mounting rail cavities that terminate at one end in a pair of flange recesses. A vertical tongue portion extends downwardly from the conductor body transversely across the leg portions at the other end of the cavities, the tongue portion having a width that is greater than the thickness of the metal sheet. When the conductor body is mounted on the mounting rail with one flange extending within the recesses, a spring biases the conductor body in a direction to effect electrical engagement between the other rail flange portion and the adjacent surface of the tongue portion.
