Abstract
The utility model discloses an electromagnetic sensing system applied to a miniature circuit breaker, which comprises a current coil 1, wherein a voltage coil is plugged inside the current coil 1, anda connecting terminal of the current coil 1 is welded with a fixed contact 2 via a welding point 11. The electromagnetic sensing system also comprises a magnetic yoke 3, and the fixed contact 2 is intightly engaged connection with the magnetic yoke 3. The electromagnetic sensing system has the advantages that only the current coil is welded with the fixed contact, and the fixed contact is directly engaged with the magnetic yoke after being welded, thereby improving assembling process of products, and lowering processing cost and saving materials as the overall system just has one welding point and no riveting point.
Description
Technical field
The utility model relates to a kind of circuit breaker, particularly a kind of EM induction system of circuit breaker.
Background technology
As shown in Figure 1, be inserted with electricity line ball circle in the current coil 1, the space is more saved like this, more compact structure, and the terminals of current coil 1 are by pad 11 and fixed contact 2 welding, and fixed contact 2 is connected by riveting point 21 riveted joints with yoke 3.In the process of riveted joint, part is many, troublesome poeration.
Summary of the invention
At the deficiencies in the prior art, the utility model provides a kind of EM induction system of novel miniature circuit breaker.
To achieve these goals, technical solution adopted in the utility model is: a kind of EM induction system that is applied to miniature circuit breaker, comprise current coil 1, be inserted with potential winding in the current coil 1, the terminals of current coil 1 and fixed contact 2 are by pad 11 welding, also comprise yoke 3, fixed contact 2 is connected with yoke 3 close-fittings;
Described fixed contact 2 is connected with the groove close-fitting of yoke 3;
Described groove is square groove, dovetail groove or cone tank.
The beneficial effects of the utility model: have only the welding of current coil and fixed contact, after welding is good, directly and yoke cooperate, the assembly process process of raising product, whole system has only a pad, no riveted point can cut down finished cost and saves material.
Description of drawings
The structure chart of the EM induction system of Fig. 1, existing miniature circuit breaker.
The structure chart of Fig. 2, EM induction system of the present utility model.
Embodiment
See also its implementation process of description of drawings:
A kind of EM induction system that is applied to miniature circuit breaker comprises current coil 1, is inserted with potential winding in the current coil 1, and compound mode makes in a narrow space like this, realizes the residual current induction and the big induction by current that transships simultaneously.The terminals of current coil 1 and fixed contact 2 also comprise yoke 3 by pad 11 welding, and fixed contact 2 is connected with the close-fitting of the groove of yoke 3.Described groove is the groove of square groove, dovetail groove or cone tank or other form.Close-fitting connects like this, does not just need riveted, and is so not only convenient but also save material.
The beneficial effects of the utility model; Only have the welding of current coil and static contact, after welding is good, Direct and yoke cooperates, and improves the assembly process process of product, and whole system only has a pad, No riveted point can cut down finished cost and saves material.
