Description

Modular system for producing a connection device having a plurality of connection terminals Technical Field The invention relates to a modular system for producing a connecting device according to the preamble of claim 1 and to a connecting device produced using such a modular system. Background Such a modular system should be used for manufacturing a connection device having a plurality of connection terminals for connecting electrical conductors. The modular system comprises a set of housing parts which can be aligned with each other in the direction of alignment for mounting the connecting device and a set of spring elements which each have a clamping leg. In the installed state of the connection device, each connection terminal corresponds to a spring element. The respective spring element is configured for acting on the electrical line in the clamped position to connect the line to the respective connection terminal. The connection means for example comprise a plurality of connection terminals to which electrical leads can be connected. For this purpose, a housing part is associated with the connection terminals, on which housing part a contact element having a contact section for electrical contact with the electrical conductors and a spring element having a clamping leg which can be moved relative to the housing part are arranged. The clamping leg of the spring element is configured to act clampingly on the electrical conductor for contact with the contact section. The connection terminals each implement a spring force connection by using a spring element, wherein the electrical lines are clamped with the contact element in the connection position under the elastic spring action of the spring element and are thus electrically connected to the contact element. In the connection terminal disclosed in DE 10 2019 127 464 B3, a spring element is provided in the form of a tension spring, which pulls the connected electrical conductor against the corresponding contact element by means of an elastic spring action 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 placement and is clamped between the clamping leg and the contact element in the connecting position. A locking device is provided in the connection terminal of DE 10 2019 127 464 B3, by means of which the clamping leg is locked in the release position relative to the housing. When the electrical line is inserted, the latching device is activated and the latch is thus released, so that the clamping leg is displaced from the release position and thereby clamps the electrical line with the contact element. In order to transfer the clamping leg into the release position, in particular in order to be able to place 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 legs takes place directly by means of a tool, whereas in the connection terminals known from DE 10 2019 135 203 A1 and DE 10 2020 104 140 A1, in each case an actuating element in the form of a so-called push button (Pusher) is provided, which can be pushed into the housing of the connection terminal in order to act on the clamping legs in this way and to displace the clamping legs into their release position. The actuating elements are each preloaded against the housing springs of the connection terminals via a tensioning spring in the form of a compression spring. In the connection terminal disclosed in DE 10 2019 135 203 A1, an actuating projection is provided on the actuating element, which actuating projection hooks onto a fastening section of the holding element in the actuating position of the actuating element. In the connection device, the housing parts can be attached to one another in the direction of arrangement for mounting, so that a connection block is obtained which realizes the connection device and to which a plurality of electrical conductors can be connected. Thus, the connection terminals may be combined with each other and arranged side by side, thereby providing an assembly of a plurality of interconnected connection terminals in this way. The connection terminals may be constructed in a sheet-like structure (a sheet-like extension having a relatively thin width and along a plane perpendicular to the arrangement direction) and attached to each other for obtaining the connection means. The sheet-like structure of the connection terminal has the advantage that this increases the play in order to facilitate, for example, the mounting of the contact element and the spring element on the housing part of the connection terminal. The housing parts of the connection terminals can be designed su
