Abstract
The utility model provides a kind of switch with knifeshaped fuse arc-chute, comprise box body, lid and copper bar, described box body and lid are insulating element, described tray interior is symmetrical and be arranged with some slideways in parallel, described copper bar is arranged by slideway is vertical with box body, leave space between each copper bar, described lid and box body grafting are fixed; Described switch with knifeshaped fuse arc-chute, structure is simple, and copper bar is changed convenient.
Description
Technical field
The utility model relates to a kind of switch fitting, especially a kind of switch with knifeshaped fuse arc-chute.
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.
Utility model content
Technical problem to be solved in the utility model is to provide a kind of switch with knifeshaped fuse arc-chute.
For solving the problems of the technologies described above, the technical solution of the utility model is:
A kind of switch with knifeshaped fuse arc-chute, comprise box body, lid and copper bar, described box body and lid are insulating element, described tray interior is symmetrical and be arranged with some slideways in parallel, described copper bar is arranged by slideway is vertical with box body, leave space between each copper bar, described lid and box body grafting are fixed.
Preferably, above-mentioned switch with knifeshaped fuse arc-chute, described copper bar is rectangle structure, is provided with U-shaped groove in the middle part of it.
The beneficial effects of the utility model are:
Above-mentioned switch with knifeshaped fuse arc-chute, structure is simple, and copper bar is changed convenient, and the structural design of copper bar uniqueness makes electric arc breaking capacity strong, effectively can carry out arc extinguishing fast.
Accompanying drawing explanation
Fig. 1 is the structural representation of a kind of switch with knifeshaped fuse arc-chute that the utility model provides;
Fig. 2 is the structure of copper bar schematic diagram of a kind of switch with knifeshaped fuse arc-chute that the utility model provides.
In figure: 1-box body 2-lid 3-copper bar
Embodiment
For further illustrating the utility model, accompanying drawing is now coordinated to be described in detail:
As shown in Figure 1-2, described switch with knifeshaped fuse arc-chute, comprises box body 1, lid 2 and copper bar 3, and described copper bar is rectangle structure, U-shaped groove is provided with in the middle part of it, described box body and lid are insulating element, and described tray interior is symmetrical and be arranged with some slideways in parallel, and described copper bar is arranged by slideway is vertical with box body, space is left between each copper bar, described lid and box body grafting are fixed, and lid can take off, and are convenient to change copper bar.
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.
