Description

In a known interrupter lever of this type which extends through the insulating piece 11. This is the leaf spring partially cast in the insulating piece end of the leaf spring 16, which is removed from the contact 15. Since there is no rivet for fastening the leaf spring, it is anchored to the angle plate, but is turned against , the breaker lever is relatively isolated.

a bit easy. The manufacture of such a sub- The insulating piece 11 is with a passage to

breaker lever bit but quite complex. First of all, receiving the spring 16 is formed. The passage in the leaf spring must be exactly positioned in the casting mold. The insulating piece has a width that is equal to the width. Care must then be taken to ensure that the spring is, and has a depth equal to the strength, that the mold is on the areas of the leaf spring, so that the spring is in a firm position that is not cast in with it should be tightly seated in this passage . So that it is brought out. The difficulties with the ge spring together with the contact 15 due to the insulating positioning of the leaf spring in the casting mold insert piece 11 for assembling the parts are so great that a higher zen can be achieved during manufacture, the walls the passage in the insulation committee due to lack of accuracy results in 4 ° piece 11 at 17 and 18 recessed to the contact (German utility model I 814261). 15 and pick up the head of the rivet with the

The invention is based on the object of one of the contacts 15 being attached to the spring. To create the interrupter lever which, with a small diameter of the contact 15 and the diameter weight, can be precisely relocated without difficulty, the head of the rivet are considerably smaller than the width of the spring 16, so that only Parts of the solves that in the insulating piece a channel which is adapted to slide through walls of the passage in the insulating piece II is provided and is adapted to the leaf spring. The remaining parts of the walls of the through the leaf spring against axial displacement by means of gangs lie against the spring 16. In order to secure the spring 16 in the desired position relative to the insulating piece 11 in the spring tabs supported on the insulating piece. 50 lock, the spring is with two inclined spring tabs

The breaker lever according to the invention is formed in 19 and 21, each made at the opposite two stages. First of all, the insulating ends of the insulating piece 11 are made to attack if the insulating piece. Since the leaf spring is in the intended position at this point in time, the spring 16 has not yet been inserted, it can be manufactured with holiier accuracy without any sealing problem. Arrival 55'Herstück 11, the tab 21 is inserted by engagement with the closing, the leaf spring due to its up to-wall of the passage in the insulator 11 ausgeborückbiegendeot spring tabs without difficulty in gene order int the channel in alignment with the main part of the spring insulator and fixed 16 to lie. Here are the dimensions of the Isowden. Since the spring tabs can be positioned precisely in the leaf liner II and the distance between the tabs 19 and spring, the axial position of the So 21 can be provided so that the end of the tab 21 is not fixed with the greatest accuracy from the end of the leaf spring Passage in the insulator 11 the. Since the cross-section of the channel has the dimensions that come out until the end of the tab 19 corresponds to the leaf spring, the leaf spring is firmly fixed in the system at the opposite end of the insulating channel. The weight of the interruption piece II is located. After that, the tab 21 as bels is small, because no rivet is needed for fixing the 1S5 of the outward spring to attach to the associated leaf spring. - To rest the end of the insulating piece 11 and thus the

It is known that a breaker lever spring 17 and the contact 15 in the desired a Abienkstück, which locks on a leaf spring with a position relative to the insulating piece 11.
