BACKGROUND OF THE INVENTION The present invention relates to a high current relay consisting of a coil body with a coil core and a yoke mounted thereon, wherein the yoke is operably connected to the relay housing by an anchor which actuates the contacts according to its tilt position.

It is known for a high current switching relay that has a dual MCC so-called. with switching protection. This relay has been designed to provide high currents with a design such that the relay can be connected directly to its corresponding high current terminal by its terminal contacts and provide a particularly safe contact. However, this relay for switching high currents has the disadvantage that it uses relatively high actuating power for switching.

However, for versatile applications, it is a requirement that the relay suitable for switching high currents be operated at low power and, for example, be equipped with a circular control device. In such cases, the aim is to switch high currents via an electronic ve /. Until now, I have used, among other things, additional circuit protection.

The foregoing drawbacks were addressed in U.S. Patent No. 522,285. A high-current relay as described in Swiss Patent No. 5,198, wherein the electromagnet coil body acts on a hinged, permanent magnet bearing anchor which closes or opens its latching contacts via a spring-loaded contact bridge in accordance with its respective tilt position. Opposite contacts to the relay housing are located opposite the spring load contact bridge. In addition, the lever is provided with an externally actuated lever arm for adjusting the desired tilt position externally, while at the same time being used to display the current tilt position externally. The pivoting anchor is provided with a cut-out into which a pin protruding from the contact bridge extends. Thus, the case of a spring-loaded contact bridge is shifted in one direction or another as a function of the current tilting position of the anchor. The disadvantage of this solution is that relatively high friction between the stud and the receiving cavity, i.e. its edges, must be overcome. This, however, leads to relatively large current shocks, which are necessary for the switching movement to take place at all,

SUMMARY OF THE INVENTION It is an object of the present invention to further develop the above solution and to provide a high current relay that has significantly less frictional forces in the actual switching process, i.e., anchor tilt.

The object of the present invention has been solved by the spring-loaded contact bridge being removably mounted on a cylindrical pin provided for cutting the anchor against the force of the springs.

This eliminates the need for earlier high-force motion transmission through the pin contacting the flange of the anchor cavity, since according to the invention it is. the contact bridge itself is directly connected to the anchor and thus takes over its tilting motion.

According to the invention, it is advantageous if the counter contacts fixed to the relay housing are connected to the output terminal clamps. Thus, the relay according to the invention can be directly connected to the current-carrying circuits for switching said high currents.

The relay of the present invention will now be described in more detail with reference to an exemplary embodiment of the drawings, in which the drawings illustrate other features and advantages of the relay of the present invention. In the drawing, Fig. 1 is a longitudinal sectional view of the relay according to the invention in section 1-1 of Fig. 2, Fig. 2 is a perspective view of Fig. 3 in the direction of arrow II, and Fig. 3 is a view of Fig. You can see his view towards the third corner.

The relay consists of a spring block 1, which is fitted with outlet hose couplings consisting of a hollow connector 21 and a cylindrical screw 22. These pull-out terminal couplings are connected to the respective contact portions by means of a connecting bracket 23. The spring block 1 is releasably secured to the vehicle 3 by means of cylindrical screws 18. The actuator system consists of a coil body 2, a yoke 3 and a yoke 4 mounted on the other side of the coil body 2, which is fixed to the spring block 1 by means of a countersunk screw 19. The magnetic circuit of the coil core 5 is formed by the passageways 3 and 4.

The magnetic circuit is closed by a permanent magnet 8 which is mounted at the hinge point 24 between the tilting anchor plate 10 mounted on the relay. The anchorage 9 of the anchor 9 has a lever 7 which extends into the cut-out of the cover 20 of the lip, so that the position of the lever 7 of the anchor 28 shows both the switching position and the possibility of manually engaging the anchor 9.

The connections of the coil body 2 are terminated to the hot tips 6, through which they can be connected to an electronic actuator system.

The essence of the double contact break contact system is that the anchor clamp 28 of the anchor 9 is provided with a cut-out in which a cylindrical pin 15 is fixed and an axially slidable contact bridge 14 is provided. The contact bridge 14 is moved by pushing niggers 16 on both sides, which are pressed against it by discs 17 arranged on the front portions of the contact bridge 14.

In the position shown in Fig. 3, the contact pin 14 is positioned directly on one side of the counter-contact 27 and is guided to the pull-out terminal connectors via a connecting pin 23. Contact 14-21

186,779 is pressed against the corresponding counter contact 27 by the force of the compression spring 16. Thus, the contact bridge 14 is mounted at the free, tiltable end of the anchor 9 so that it can be tilted in the intermediate space 25 between the counter contacts 26, 27. 5

Figure 2 shows that a total of three retractable clamp outlet connectors are provided with three bent contacts 11, 12, 13.
