Abstract
The utility model provides a kind of switch with knifeshaped fuse spring, and the middle part with loop configuration is provided with the spring body of otch, and described spring body is square spring, and the edge of described otch is parallel to each other; Described switch with knifeshaped fuse spring, utilizes its distinctive structure the fuse of switch with knifeshaped fuse and fixed contact closely to be fixed, though structure is simple, has very important using value.
Description
Technical field
The utility model relates to a kind of switch fitting, especially a kind of switch with knifeshaped fuse spring.
Background technology
Switch with knifeshaped fuse is the simplest in manual electrical equipment and most popular a kind of low-voltage electrical apparatus, it is the closed of wall scroll control switch and disconnection, as directly dialled on handle, the movable contact spring of circle cutter is contacted with static contact, thus realizing circuit is closed, when handle is set aside, dynamic, static contact disconnects, circuit disconnects, in use, when bearing power is excessive, the excessive fuse that will make of electric current flowing through fuse generates heat and fuses, play the effect of protective circuit, after fixing a breakdown, change fuse, continue to use, it is generally used in the backbone in lighting circuit, the switch with knifeshaped fuse of prior art meets the needs in market to a certain extent, but the installation of existing switch with knifeshaped fuse is very inconvenient, and contact easily punctures generation electric arc, and then calcination is produced to human body.
Existing switch with knifeshaped fuse adopts and is welded and fixed, very inconvenient when changing, and uses flexible connection to be not easy to fix.
Utility model content
Technical problem to be solved in the utility model is to provide a kind of switch with knifeshaped fuse spring.
For solving the problems of the technologies described above, the technical solution of the utility model is:
A kind of switch with knifeshaped fuse spring, the middle part with loop configuration is provided with the spring body of otch, and described spring body is square spring, and the edge of described otch is parallel to each other.
Preferably, above-mentioned switch with knifeshaped fuse spring, combined by several spring body arranged in parallel, each spring body side is provided with chute, and opposite side is provided with projection, and described chute cooperatively interacts with projection and is connected.
The beneficial effects of the utility model are:
Above-mentioned switch with knifeshaped fuse spring, utilizes its distinctive structure the fuse of switch with knifeshaped fuse and fixed contact closely to be fixed, though structure is simple, has very important using value.
Accompanying drawing explanation
Fig. 1 is the structural representation of a kind of switch with knifeshaped fuse spring that the utility model provides.
In figure: 1-spring body 2-chute 3-projection
Embodiment
For further illustrating the utility model, accompanying drawing is now coordinated to be described in detail:
As shown in Figure 1, described switch with knifeshaped fuse spring, the middle part with loop configuration is provided with the spring body 1 of otch, described spring body is square spring, the edge of described otch is parallel to each other, and can combine by arranged in parallel between described spring body, each spring body side is provided with chute 2, opposite side is provided with projection 3, and described chute cooperatively interacts with projection and is connected.
The above is only preferred implementation of the present utility model; it should be pointed out that for those skilled in the art, under the prerequisite not departing from the utility model principle; can also make some improvements and modifications, these improvements and modifications also should be considered as protection range of the present utility model.
