Description

The invention relates to a conductor terminal with an insulating housing and at least one spring-loaded clamping connection for connecting an electrical conductor by means of spring force, wherein the insulating housing has at least one conductor entry opening for inserting an electrical conductor in a conductor entry direction, wherein the at least one spring-loaded clamping connection has at least one busbar and a clamping spring, which has a clamping leg with a clamping edge for clamping an electrical conductor to a contact section of the busbar, with a retaining element which is configured to hold the clamping leg in an open position, and with a release element with a release section, wherein, when an electrical conductor to be clamped exerts an actuating force on the release section of the release element, the retaining element is thereby deflectable to such an extent that the clamping leg held in the open position on the retaining element can be released from the retaining element. Such a conductor terminal block is made from the DE 10 2020 119 372 A1 This is a conductor terminal with automatic connection of the electrical conductor to be connected when it is inserted into the terminal. Inserting the conductor automatically releases the clamping arm of the spring, which is held in an open position, thus clamping the conductor securely. Based on this, the object of the present invention is to provide a further improved conductor terminal. This problem is solved in a conductor terminal of the type mentioned above by providing the terminal with a deflection mechanism designed to redirect a displacement of the release section in the conductor entry opening caused by the electrical conductor into a movement of the retaining element. In this movement, at least one first locking element of the retaining element, engaged with the clamping leg, performs a movement with a component opposite to the conductor entry direction. This allows for a particularly compact, low-profile integration of an automatic release function of the clamping leg into a conductor terminal. In particular, it becomes possible to integrate the additional elements required for the automatic release function, such as the retaining element and the release element, into the conductor terminal in a structurally advantageous manner and/or to form them integrally with the clamping spring. Advantageously, the design of the clamping spring is not excessively complex compared to known spring-loaded clamping connections. The retaining element can thus have at least one first locking element, and the retaining element can also have several first locking elements, e.g., two first locking elements, for example, first locking elements arranged on opposite sides of the clamping leg, each of which can be locked to the clamping leg. The first locking element can be spring-loaded in the open position by the clamping leg. The clamping leg can have at least one second locking element, which can be locked to the at least one first locking element in the open position. The second locking element can, for example, be designed as a locking edge or locking projection on the clamping leg. It is also possible that at least one locking tab is projected on the clamping leg, on which such a second locking element is located. The retaining element can be designed as a separate component from the clamping spring, attached, for example, to an insulating housing of a conductor terminal, to the busbar, or to another component. Alternatively, the retaining element can be formed integrally with the clamping spring. Such a design, particularly a clamping spring integrally formed with the retaining element, allows for the integration of automatic connection technology into spring-clamp terminals and conductor connection terminals of various designs. In particular, proven conductor connection terminals of known designs can be easily upgraded to automatic connection functionality, i.e., with automatic conductor connection of the electrical conductor to be clamped. Advantageously, an automatic connection function can be easily and compactly integrated into existing conductor connection terminal designs. No additional retaining element is required for the holding function, which simplifies the assembly of the conductor connection terminal. The retaining element can be movably arranged, e.g., sliding, pivoting, or otherwise deflectable, so that it can be easily deflected by the inserted conductor to achieve the desired release of the clamping arm from the retaining element. The retaining element can, for example, be mounted so that it can be moved in a linear or arc-shaped direction. The retaining element can also be mounted so that it can pivot. In this case, the retaining element can pivot about a fixed or variable pivot axis. In the case of a variable The pivot axis can be such that the retaining element is, for example, mounted on a floating pivot. The retaining element can also
