Abstract

The invention relates to a connection terminal (1) comprising a housing (10) and a contact element (11) for making electrical contact with an electrical line (2). The spring element (12) has a support leg (121) and a clamping leg (120) which is designed to act on the electrical conductor (2) in a clamped position in order to bring the electrical conductor (2) into contact with the contact section (110) of the contact element (11). The triggering element (123) can be adjusted relative to the housing (10), wherein the clamping leg (120) can be released from the release position by the interaction of the triggering element (123) with the electrical line (2). A holding element (13) connected to the actuating element (14) and movable together with the actuating element (14) is designed to latch with the triggering element (123) in order to hold the clamping leg (120) in the release position, wherein the actuating element (14) is at least partially made of a first material and the holding element (13) is at least partially made of a second material different from the first material.

Description

Terminal for connecting electrical conductors Technical Field The invention relates to a connection terminal for connecting electrical conductors according to the preamble of claim 1. Background Such a terminal comprises a housing having a plug opening into which an electrical conductor can be inserted in a plug direction for connection to the terminal. A contact element is arranged on the housing for electrical contact with the electrical line. The contact element has a contact section. The spring element has a support leg which is supported relative to the housing and/or the contact element, and a clamping leg which is elastically adjustable relative to the support leg. The clamping leg is configured to act on the electrical conductor in the clamping position in order to bring the electrical conductor into contact with the contact section. The clamping leg can be adjusted relative to the housing from a clamping position into a release position for releasing the electrical conductor. The clamping leg is held in position relative to the housing in the release position. The actuating element can be moved relative to the housing for adjusting the clamping leg into the release position. The triggering element can be adjusted relative to the housing, wherein the clamping leg can be released from the release position by the interaction of the triggering element with the electrical line. Such a connection terminal is realized by using a spring element, wherein the electrical conductor is clamped with the contact element in the connection position under the elastic spring action of the spring element and is thus electrically connected to the contact element. In the connection terminals known from DE 10 2019 127 464 B3, a spring element is provided in the form of a tension spring which, by means of an elastic spring action, pulls the connected electrical conductor into abutment with the associated contact element and thus establishes a clamping connection between the electrical conductor and the contact element. For this purpose, the electrical conductor is moved through the opening in the clamping leg during attachment and is clamped between the clamping leg and the contact element in the wiring position. In the connection terminal of DE 10 2019 127 464 B3, a locking device is provided, by means of which the clamping leg is locked in the release position relative to the housing. When the electrical conductor is inserted, the locking device is activated and the latch is thus released, so that the clamping leg is adjusted out of the release position and the electrical conductor is thereby clamped with the contact element. In order to transfer the clamping leg into the release position, in particular in order to be able to attach the electrical conductor or to release the connected electrical conductor from the connection terminal, a tool, for example a screwdriver, can be attached to the connection terminal and a force can be applied to the clamping leg thereby. In DE 10 2019 127 464 B3, the adjustment of the clamping leg takes place directly by means of a tool, whereas in the terminals known from DE 10 2019 135 203 A1 and DE 10 2020 104 140 A1, actuating elements in the form of so-called push buttons (Pusher) are provided, respectively, which can be pressed into the housing of the terminal in order to act on the clamping leg in this way and to shift the clamping leg into its release position. A connection terminal is known from CN 110391508A, in which a locking hook for locking with a spring leg is formed on the actuating element. Disclosure of Invention The object of the invention is to provide a connection terminal which can be used in a wide variety while achieving an advantageous electrical contact and which, while being of simple construction, is reliably activated when connecting electrical conductors. This object is achieved by the subject matter having the features of claim 1. The connection terminal has a holding element connected to the actuating element and movable together with the actuating element, which is designed to latch with the triggering element in order to hold the clamping leg in the release position, wherein the actuating element is at least partially made of a first material and the holding element is at least partially made of a second material that is different from the first material. In the connection terminal, the electrical conductor is in electrical contact with the electrical contact element in that, when the electrical conductor is inserted into the insertion opening, the clamping leg acts on the electrical conductor and spring-loads the electrical conductor in the direction of contact with the contact element. In order to facilitate the insertion of the electrical conductors or in order to be able to release the connected conductors, the clamping legs of the spring element can be elastically deflected in order to transfer the clamping legs in this way into a release position in wh
