DE1465432C - Electromagnetic switching regulator - Google Patents

Description

The invention relates to an electromagnetically operating switching regulator according to the OB of claims 1 and 2. Such a controller is described in German Patent 824,967.

In this known controller, the Auslen-. The leaf spring can only be adjusted together with the usable length can be set.

In contrast, the object of the present invention is to design the controller in such a way that that at least two parameters of the leaf spring can be set independently of one another.

A first solution to this problem is given in the characterizing part of claim 1,
ίο A second solution to this problem is given in the characterizing part of claim 2.

With the solutions according to the invention, the advantage is achieved that the adjustment of the controller is more precise than can be done with the known controller. This is especially important when the regulator is on Is a three-point controller and thus the adjustment of three contacts must be coordinated with one another.

Appropriate refinements of the two solutions are given in the subclaims.
The drawings represent possible embodiments of the controller according to the invention.

F i g. 6 and 7 represent a third and fourth exemplary embodiment according to the first proposed solution.

The controller (FIGS. 1 and 2) has a frame 1 on which an iron core 2 is arranged. To the Iron core 2, the excitation effect 3 is arranged. On the frame 1 is also a movable contact part arranged on which a leaf spring 5 is attached. The joint of the contact part 4 on the frame 1 can be formed by a separate leaf spring 6, as shown in FIG. 1 and 2 shown, or else it can consist of the extension of the leaf spring 5. Furthermore, the contact part has a contact point 7, which is connected to a fixed contact on the Frame 1 is arranged, cooperates.

The free end of the spring 5 is supported on the edge 9, a cam, the cam 9 being arranged on the frame 1 at the front. A toothed section 9 ₂ makes it possible to rotate the cam 9 for precise adjustment of the return force of the spring 5.

To change the useful length of the leaf spring 5, the cam 9 is arranged to be exchangeable. For this is the cam 9 by means of a screw 10 welded on the frame 1 or over any other suitable means is connected to it, and a nut 11 is attached to the frame.

This embodiment makes it possible, by selecting a suitable cam, the support point of the Change spring.

It should be noted that the profile of the various possible cams is identical or different can be to allow greater sensitivity of the setting. In contrast, however, is the orientation the cam edges different.

In Fig. 2, three cams are shown as an example. Cam 9 occupy several positions. For this purpose, the spring 5 can be turned in the fastening area in order to change the flexibility of the Fe-elongated holes 14, which are mass-produced and optionally available, by changing their useful length through the contact part arranged guide screws 15 shifting their point of support on the stop 5 cooperate.

Claims (7)

Patent claims: 1. Electromagnetically operating switching regulator with an electromagnet attached to a frame, with a contact part to be moved by the electromagnet and with a leaf spring that carries the contact part and acts against the action of the electromagnet and is attached to the frame, the deflection of which is adjustable, characterized by a Support (9, 12, 13; 9 a, 9 b, 9 c; 9, 14, 15; 16, 17, 18; 19), the point of application of which engages the leaf spring at a distance from the leaf spring attachment on the frame and both in the longitudinal direction of the Leaf spring (5) and independently of this, can be adjusted perpendicular to the surface of the leaf spring (5) (FIGS. 1 to 4 and 6, 7). 2.
