Abstract
The utility model discloses a casing of a communication processor with photoelectric isolation for a mine, which is provided with a casing body, wherein the casing body is cylindrical, a hollow cavity is arranged in the casing body, the top end and the bottom of the hollow cavity are respectively provided with steps, a boss in the shape of a circular ring is arranged on the outer wall of the middle part of the casing body, the outside of the lower end of the casing body is sleeved with an outer embedding sleeve, and the outer embedding sleeve is formed by bending and welding a stainless steel plate. According to the casing of the communication processor with photoelectric isolation for the mine, a circuit board with electronic elements, such as a photoelectric coupler and the like, is sealed and filled in the casing by using stainless steel to process the casing through epoxy resin, which not only prevents explosion but also prevents moisture. When the casing of the communication processor with photoelectric isolation for the mine is used, the processor is installed in the explosion-proof holes of the baffle plates of two independent explosion-proof box bodies and is also fastened by nuts. The casing of the communication processor with photoelectric isolation for the mine has a simple and reliable structure and high safety coefficient.
Description
Technical field:
The utility model relates to blower fan field, colliery, specifically is that a kind of mining photoelectricity is isolated the Communication processor shell.
Background technology:
It is information communication device between the computer of duplicate supply or three power supply controller of fan independently under the coal mine that mining photoelectricity is isolated Communication processor, its two ends connect two controllers in the explosion-proof casing of independence respectively by the multicore connector, make the controller on both sides can realize mutual communication, can the signal of telecommunication be isolated mutually by photoelectric isolation technology again, realize that coal mine downhole safety needs.Its application has solved a road of duplicate supply under the coal mine or three power supply fan switch another road safe difficult problem of maintenance of opening the door of can not cutting off the power supply of working.But because the particularity of workplace all has very high requirement for dustproof grade of explosion-proof protection against the tide, the cast housing of Cai Yonging can't reach the technical parameter requirement in the past, had potential safety hazard under the long-term situation about using, and therefore imagination provides a kind of new shell to substitute.
Summary of the invention:
The utility model provides a kind of mining photoelectricity to isolate the Communication processor shell, and by using stainless steel processing shell, the circuit board that electronic component such as photoelectrical coupler is housed is filled in the shell by the epoxy resin envelope, and is not only explosion-proof but also moistureproof.Processor is installed in the explosionproof hole of two explosion-proof box partitions of independence during use, and fastening by nut, and it is simple and reliable for structure, the coefficient of safety height.
The technical solution adopted in the utility model is:
A kind of mining photoelectricity is isolated the Communication processor shell: have a housing, housing is a cylindrical shape, and cavity is arranged in the housing, and cavity top, bottom are respectively arranged with step, and housing middle part outer wall is provided with round ring boss, is set with outer nested outside the housing lower end.
Described outer nestedly be welded for the corrosion resistant plate bending.
Advantage of the present utility model is:
The utility model is by using stainless steel processing shell, and the circuit board that electronic component such as photoelectrical coupler is housed is filled in the shell by the epoxy resin envelope, and is not only explosion-proof but also moistureproof.Processor is installed in the explosionproof hole of two explosion-proof box partitions of independence during use, and fastening by nut, and it is simple and reliable for structure, the coefficient of safety height.
