Abstract
The utility model discloses a housing of a universal changeover switch, which comprises an end cover, a thread bushing, a base and screw hole plugs, wherein the end cover, the thread bushing, the base and the screw hole plugs are sequentially connected in a threaded manner. The housing is characterized in that a changeover portion of a changeover switch body is disposed in the thread bushing, and a knob of the changeover switch is disposed outside the end cover. Threads are arranged at the bottom end of the end cover, two ends of the thread bushing and the top ends of the screw hole plugs of the housing respectively, so that when a single universal changeover switch is used, protection can be achieved only by mounting the end cover and the base outside the universal changeover switch. When multiple universal changeover switches are used, reliable protection can be achieved only by adding one thread bushing between the thread bushing and the base for each addition of one to two universal changeover switches.
Description
Technical field
The utility model relates to low-voltage circuit, relates in particular to the shell of low-voltage electrical apparatus, specifically a kind of shell of universal seclector.
Background technology
The existing universal seclector in current market does not generally all have the shell protection, has dust, water droplet to enter easily so use in comparing rugged environment, makes switch that very big potential safety hazard be arranged in actual use.Even there is the degree of protection of shell protection also lower, shell all is to be connected and fixed with screw, installs cumbersome and barrier propterty is relatively poor, and a kind of shell can only be protected a kind of universal seclector of joint number.
Summary of the invention
To be solved in the utility model is the prior art above shortcomings, aims to provide the shell of a kind of degree of protection height, wide adaptability and universal seclector easy for installation.
The technical scheme that addresses the above problem employing is: a kind of shell of universal seclector, comprise the end cap, the thread bush that are threaded successively, base and nut insert, the conversion portion that it is characterized in that the change over switch body places in the described thread bush, and the knob of change over switch places the outside of described end cap.
The shell of universal seclector of the present utility model, in the end cap bottom, thread bush two ends and nut insert top all be threaded, when using the universal seclector of single-unit, only need end cap and base are installed in the universal seclector outside, just can play the effect of protection.If when using the universal seclector of more piece, the universal seclector of every increase by 1～2 joint only needs to increase the effect that can play reliable protection once the joint thread bush in the middle of thread bush, base.
According to the utility model, described thread bush is 1 to a plurality of, and quantity is identical with the joint number of change over switch, adopts between adjacent thread overlaps to be threaded.
As further improvement of the utility model, the junction of described end cap and change over switch body is provided with sealing ring.The junction of described base and nut insert also is provided with sealing ring.
Description of drawings
The utility model is described in further detail below in conjunction with drawings and Examples.
Fig. 1 is a structural representation of the present utility model.
Fig. 2 is an assembling process schematic diagram of the present utility model.
Embodiment
With reference to Fig. 1, the shell of universal seclector of the present utility model comprises the end cap 2, the thread bush 3 that are threaded successively, base 4 and nut insert 5, the conversion portion of change over switch body 1 places in the described thread bush 3, and the knob 6 of change over switch places the outside of described end cap 2.Described end cap 2 is provided with the sealing ring (not shown) with the junction of change over switch body 1.Described base 4 is provided with the sealing ring (not shown) with the junction of nut insert 5.
With reference to Fig. 2, assembling process of the present utility model is as follows:
1, earlier the conversion portion 8 of change over switch body 1 is placed in the end cap 2, the axle of change over switch body 1 is loaded onto the centre bore 9 that passes behind the sealing ring on the end cap 2; On two screws 10 of end cap 2, respectively place a sealing ring, be covered with the cover plate 7 of change over switch body 1, change over switch body 1 is fixed on the end cap 2 with screw at end cap 2 outer surfaces.
2, screw on thread bush 3 in the inboard of end cap 2.
3, the opposite side at thread bush 3 screws on base 4.
4, after putting sealing ring respectively on two nut inserts 5, screw in base 4.
In the above-described embodiment, described thread bush 3 is 1.But the utility model is not limited thereto.The number of described thread bush 3 can be for 1 to a plurality of, decide according to what of the joint number of change over switch, thread bush 3 quantity are relevant with the joint number of change over switch, and the every increase by 1～2 of the joint number of change over switch saves, need to increase a thread bush, adopt between the adjacent thread cover 3 to be threaded.
What should be understood that is: the foregoing description is just to explanation of the present utility model, rather than to restriction of the present utility model, any innovation and creation that do not exceed in the utility model connotation scope all fall within the protection range of the present utility model.
