Abstract
The utility model provides a breaker, it includes: moving contact and static contact, the moving contact rotates and sets up in a pivot, the outer detachably in moving contact both ends is provided with the protecting crust, the protecting crust skin is provided with the elastic component, the moving contact with static contact swing joint, the moving contact with during quiet contact connection, the elastic component butt in the static contact. Protecting the moving contact through the protective housing, keeping area of contact by the elastic component when moving contact breaks away from with the static contact, avoid the electric current too big to the burning out of moving contact and static contact, on the other hand is heated when burning out when the protective housing, and the protective housing is replaced to the accessible, has reduced breaker's cost of maintenance.
Description
Technical field
The utility model relates to a kind of circuit breaker.
Background technology
Circuit breaker is a kind of switching device of breaking current; mainly for the protection of electric equipment in alternating current-direct current electrical network; make it the harm from abnormal conditions such as overcurrent, reverse current, short circuit, under-voltage and electric leakages; the reliability of useful life and disjunction is leading indicator, and reliability generally reduces along with the prolongation of service time.The circuit turn-on when moving contact of circuit breaker contacts with fixed contact, when fixed contact is separated with moving contact, circuit disconnects, and contact and departs from instantaneously, produce large electric current and contact point is burnt, make service life reduction because contact area is little at fixed contact with moving contact.
Utility model content
The purpose of this utility model is the defect overcoming prior art, provides a kind of circuit breaker, and it makes spiral process simplification, improves production efficiency, reduces production cost.
The utility model is achieved in that a kind of circuit breaker, and it comprises:
Moving contact and fixed contact, described moving contact rotates and is arranged in a rotating shaft, described moving contact two ends skin is removably provided with protecting crust, described protecting crust skin is provided with elastic component, described moving contact and described fixed contact are flexibly connected, when described moving contact is connected with described fixed contact, described elastic component is connected to described fixed contact.
Further, described moving contact has external screw thread, and described protecting crust has internal thread, and described moving contact and described protecting crust are threaded connection.
Further, described protecting crust end is set to arc-shaped.
Further, described elastic component is spring steel plate.
Further, described spring steel plate is arranged at described protecting crust skin in echelon.
Further, described fixed contact has groove, and described moving contact is connected to the groove of described fixed contact.
Further, groove two inwall of described fixed contact is inwardly relatively protruding.
The beneficial effect of a kind of circuit breaker of the utility model is: protected moving contact by containment vessel; moving contact and fixed contact keep in touch area by elastic component when departing from; avoid excessive the burning moving contact and fixed contact of electric current; on the other hand; when containment vessel be heated burn time; by replacing containment vessel, reduce the maintenance cost of circuit breaker.
Accompanying drawing explanation
In order to be illustrated more clearly in the utility model embodiment or technical scheme of the prior art, be briefly described to the accompanying drawing used required in embodiment or description of the prior art below, apparently, accompanying drawing in the following describes is only embodiments more of the present utility model, for those of ordinary skill in the art, under the prerequisite not paying creative work, other accompanying drawing can also be obtained according to these accompanying drawings.
Fig. 1 is the front view of a kind of circuit breaker of the utility model embodiment;
Fig. 2 is the end view of a kind of circuit breaker of the utility model embodiment;
Fig. 3 is the axial view of the containment vessel of a kind of circuit breaker of the utility model embodiment;
Embodiment
Below in conjunction with the accompanying drawing in the utility model embodiment, be clearly and completely described the technical scheme in the utility model embodiment, obviously, described embodiment is only the utility model part embodiment, instead of whole embodiments.Based on the embodiment in the utility model, those of ordinary skill in the art are not making other embodiments all obtained under creative work prerequisite, all belong to the scope of the utility model protection.
As shown in Figure 1 and Figure 2, a kind of circuit breaker 1 of the utility model, comprising:
Moving contact 10 and fixed contact 20, described moving contact 10 rotates and is arranged in a rotating shaft 11, described moving contact 10 two ends skin is removably provided with protecting crust 30, described protecting crust 30 skin is provided with elastic component 40, described moving contact 10 and described fixed contact 20 are flexibly connected, when described moving contact 10 is connected with described fixed contact 20, described elastic component 40 is connected to described fixed contact 20.Protected by containment vessel 30 pairs of moving contacts 10, when moving contact 10 and fixed contact 20 depart from, keep in touch area by elastic component 40, avoid excessive the burning moving contact 10 and fixed contact 20 of electric current, improve the useful life of circuit breaker 1; On the other hand, when containment vessel 30 be heated burn time, by replace containment vessel 30, reduce the maintenance cost of circuit breaker 1.
Further, described moving contact 10 has external screw thread, and described protecting crust 30 has internal thread, and described moving contact 10 and described protecting crust 30 are threaded connection.The moving contact 10 and the protecting crust 30 that are threaded connection can carry out installation and removal simply, facilitate the maintenance to circuit breaker 1.
Further, described protecting crust 30 end is set to arc-shaped.
Further, as shown in Figure 3, described elastic component 40 is spring steel plate, it is outer that described spring steel plate 40 is arranged at described protecting crust 30 in echelon, specifically, when moving contact 10 contacts with fixed contact 20 or departs from, first there is deformation in the waist of trapezoidal spring steel plate 40, and trapezoidal angle of inclination makes the contact of moving contact 10 and fixed contact 20 or departs from more flexible.
Further, as shown in Figure 2, described fixed contact 20 has groove 21, described moving contact 10 is connected to the groove 21 of described fixed contact 20, groove 21 liang of inwalls of described fixed contact 20 are inwardly relatively protruding, the inwall of groove 21 projection extrudes moving contact 10 when moving contact 10 contacts with fixed contact 20, makes moving contact 10 more tight with the contact of fixed contact 20.
The foregoing is only preferred embodiment of the present utility model; not in order to limit the utility model; all within spirit of the present utility model and principle, any amendment done, equivalent replacement, improvement etc., all should be included within protection range of the present utility model.
