  • Patent number: 12021339
    Abstract: A spring terminal, in particular a direct plug-in terminal, for connecting a conductor such as a flexible stranded conductor includes a housing with a chamber and an insertion channel for inserting the conductor into the chamber. A busbar and/or a clamping cage are arranged in the housing and a clamping spring is arranged in the chamber and acts as a pressure spring. The clamping spring includes a clamping limb, said clamping limb releasable out of a latching state by a pusher having a latching edge on which the pusher can be latched in the interior of the housing on a latching hook of the busbar or another element arranged in the housing in a latching state. The pusher holds the clamping spring in a latched manner in the open position, wherein the latching edge of the pusher can be released from the latching state by an opposite movement.

  • Patent number: 11916345
    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.

  • Publication number: 20240030627
    Abstract: An assembly for contacting an electrical conductor includes a clamping spring which acts as a pressure spring for fixing an electrical conductor in a spring-force clamp and a retaining spring for locking the clamping spring in an open position such that the conductor can be introduced into a contact region in a shifting direction. The clamping spring touches the retaining spring along a contact surface in a locked state and during movement from the locking state into a unlocking state.

  • Patent number: 11824318
    Abstract: A busbar for electrically contacting an electrical conductor has two mutually opposing side walls and a bearing wall for the electrical conductor. The bearing wall extends between the side walls and transversely or substantially transversely to same, wherein the side walls and the bearing wall extend in an insertion direction and define a receiving space for receiving the electrical conductor. At least one electrically conductive projection is provided on one of the side walls and/or the bearing wall. The width of the projection is less than the width of the bearing wall.

  • Publication number: 20220416449
    Abstract: A spring-loaded terminal is designed as a direct plug-in terminal for connecting a conductor. The terminal includes a busbar for contacting the conductor, a clamping spring for retaining the electrical conductor in the terminal, and a retaining spring for latching the clamping spring in an open position so that the conductor can be inserted into a contact area. The clamping spring has a pivotable clamping leg and a clamping edge. The retaining spring has a pivotable pivoting leg having at least one retaining device as a first latching device. The clamping leg has a corresponding latching device cooperating with the retaining device of the pivoting leg in a latching state of the clamping leg. The clamping leg is adjustable from the latching state by displacing the electrical conductor into a clamping state in which the clamping leg is unlatched from the retaining device and presses the electrical conductor with the clamping edge of the clamping leg against the busbar.

  • Patent number: 10658766
    Abstract: A direct clamp terminal for connecting a conductor in the form of a flexible stranded conductor includes a housing with a chamber and an insertion conduit for inserting the conductor into the chamber. A bus bar or a clamping cage is provided in the housing and a clamping spring is located in the chamber and acts as a compression spring for securing the electrical conductor to the bus bar or the clamping cage in the area of a clamping point. The clamping spring has a clamping limb that can be pivoted about a pivoting axis and that can be shifted from a detent mode in which it is locked in a detent position into a clamping mode in which it is released from the detent mode and presses the electrical conductor against the bus bar or the clamping cage. The clamping limb can be released from the detent mode using two different shifting devices.
