Abstract
The utility model discloses a position detecting switch, which comprises a shell body, a cover plate, a mercury switch and a cable wire, wherein an internal accommodating cavity is formed by enclosing the shell body and the cover plate; the mercury switch is arranged in the inner accommodating cavity; one end of the cable wire is connected with the mercury switch and is fixedly sealed inside the shell body by adopting epoxy resin, and the other end of the cable wire is led out from the shell body. The position detecting switch adopts the epoxy resin for sealing the mercury switch and the connection between the cable wire and the mercury switch, has excellent moisture resistance and corrosion resistance performances, and can effectively prevent water, dust, gas and acid-base gases. When in use, the mercury switch controls the on-off of the circuit according to the flow of mercury in the interior, thereby realizing the detection of position changes.
Description
Technical field
The utility model relates to switching technique field, especially relates to a kind of position detecting switch.
Background technology
In mine and Chemical Manufacture unit, relevant device is able to extensive use with position detecting switch.But, the environmental condition very severe of mine and Chemical Manufacture unit, traditional position detecting switch does not possess protection against the tide, Corrosion Protection.
Therefore, directly have influence on the serviceability of traditional location sense switch.
Utility model content
Technical problem to be solved in the utility model is existing position detecting switch protection against the tide, the poor problem of Corrosion Protection.
In order to solve the problems of the technologies described above, the technical scheme that the utility model adopts is to provide a kind of position detecting switch, comprising: housing; Cover plate, encloses formation inner volume with described housing; Mercoid switch, is built in described inner volume; Cable, one end is connected with described mercoid switch and adopts Epoxy Resin to be encapsulated in described housing, and the described cable other end is drawn from described housing.
In such scheme, described housing be provided with center mounting hole and with the concentric arcuate socket of described center mounting hole.
In such scheme, the described cable other end is drawn rear employing sealing nut from described housing and is fixed.
In such scheme, described housing, cover plate and sealing nut are plastic material.
In such scheme, described mercoid switch is three foot controls, and described cable is three-core cable.
In such scheme, described mercoid switch is two foot controls, and described cable is two core cable.
The utility model, employing Epoxy Resin envelope mercoid switch and cable are connected with mercoid switch, have fabulous protection against the tide, Corrosion Protection, effectively waterproof and dustproof, anti-gas, anti-acidic and alkaline gas.During use, the inner mercury of the mercoid switch control circuit break-make that flows, is achieved detection position and changes.

Fig. 3 is the utility model position detecting switch service position figure.
In figure: 1, housing; 2, cover plate; 3, mercoid switch; 4, cable; 5, sealing nut; 6, center mounting hole; 7, arcuate socket; 8, epoxy resin.
Embodiment
Below in conjunction with specific embodiment and Figure of description, the utility model is described in detail.
The position detecting switch that the utility model provides, comprises housing 1, cover plate 2, mercoid switch 3 and cable 4.Housing 1 encloses formation inner volume with cover plate 2, and mercoid switch 3 is built in described inner volume, and one end of cable 4 is connected with described mercoid switch 3 and adopts epoxy resin 8 sealings in described housing 1, and described cable 4 other ends are drawn from described housing 1.
Wherein, described cable 4 other ends can adopt sealing nut 5 fixing after described housing 1 is drawn, and described housing 1, cover plate 2 and sealing nut 5 can be plastic material, further to improve protection against the tide, Corrosion Protection.
Shown in figure, described mercoid switch 3 is three foot controls, and described cable 4 is three-core cable.For the ease of location, described housing 1 be provided with center mounting hole 6 and with the concentric arcuate socket 7 of described center mounting hole 6, during installation, first fixed center installing hole 6 screws are too not tight, fix again arcuate socket 7 screws, the switch that swings is adjusted position, to select best operating point, then mounting screw is tightened and covered cover plate 2.
Further as shown in Figure 3, adopt the mercoid switch 3 of three pin, intrinsic two operating states, a middle pin is common port, when switch is turned left 10 ° of deflections, and common port and the connection of left side pin, when switch is turned right 10 ° of deflections, common port and the right pin are connected, and are achieved detection position and change.
Certainly, described mercoid switch (3) can be also bipod switch, and described cable (4) is correspondingly two core cable, and is not limited to the tripod mercoid switch 3 shown in figure.
The utility model is not limited to above-mentioned preferred forms, and anyone should learn the structural change of making under enlightenment of the present utility model, every with the utlity model has identical or close technical scheme, within all falling into protection range of the present utility model.
