  • the known connection terminal is designed as a security module, in which the openings provided on the connection side and their associated contact points for electrical conductors are formed with different cross sections. The two openings are arranged one above the other on a common wall of the connection side. The insertion path through the first opening to the first contact point is formed parallel to the insertion path from the first opening to the second contact point.
  • the upper contact point is designed as a spring-cage connection for accommodating conductors with small diameters and the lower contact point is designed as a screw-type contact connection for receiving conductors with larger diameters.
  • a mounting hole leads to the erjoran gleich. Through the mounting hole, a conductor inserted into the screw contact terminal can be fastened and detached with a screwdriver or the like.
  • connection terminal Based on this known connection terminal, the present invention is based on the object of providing a connection terminal as described above, in which electrical conductors can be connected and fixed from the connection side.
  • the invention solves the stated problem with the terminal described above in that the two contact points are designed as a spring terminal connection. As a result, electrical conductors can very easily be routed via the two openings arranged on the connection side to the contact points and clamped there by spring force.
  • a particularly advantageous further development of the invention provides that a mounting opening leading to one of the two clamping spring legs is provided on the connection side.
  • the clamping spring legs can be opened via a screwdriver inserted into the mounting opening, so that a flexible conductor can be guided into the opened contact point and clamped over the clamping leg.
  • the two contact points for clamping electrical conductors together is assigned a single or a respective clamping spring, which has two clamping points associated with the two clamping points, wherein the first of the two clamping spring legs is formed substantially arcuate and over its middle region clamps a conductor inserted in the first contact point assigned to it, wherein the second clamping spring leg is designed in such a way that when the conductor introduced into the second contact point is inserted, the second clamping spring leg presses against the electrical conductor with its end.
  • an inserted into the first contact point electrical conductor can be solved manually without the use of a tool by train against its insertion direction, because the first clamping spring leg presses tangentially against the electrical conductor by its arcuate configuration.
  • the configuration of the first clamping spring limb is particularly advantageous when an electrical conductor is to be connected only temporarily, for example for test purposes, and is frequently to be loosened. This may, for example, be the case with test plugs, test taps or electrical jumpers.

  • the receiving chamber legs form long contact surfaces for electrical conductors, so that currents can be transferred well and safely from an electrical conductor introduced into the receiving chamber onto the adjacent receiving legs.
  • the two receiving chamber legs form by their cutting area a bottom of the receiving chamber. It forms a boundary in the insertion direction for electrical conductors, so that the insertion depth of electrical conductors can be determined by the length of the clamping receiving chamber leg without additional parts.
  • a V-shaped receiving chamber can be produced very easily in the bending process with one process step. It only needs one leg of the metal part to be bent once to form the V-shaped receiving chamber. On the other hand, to produce a receiving chamber of a non-V-shaped geometry, an additional bend (method step) is necessary for the bottom of the receiving chamber.
