Abstract
The utility model discloses a pressure release structure of a high-voltage motor wiring box. The pressure release structure comprises a wiring box base, wherein the wiring box base is provided with two stripped voltage release holes which are distributed in a crossed way; rubber plug bars which spring out in an overvoltage state are hermetically arranged on the voltage release holes; and the heights of both sides of the rubber plug bars are greater than the widths of the voltage release holes, so that the rubber plug bars are sleeved on the wiring box base. When the pressure release structure of the high-voltage motor wiring box is under an over-high pressure, the rubber plug bars spring out. Compared with the prior art, the pressure release structure has the advantages of simple structure, saving in processing and assembling work hours, increase in the production efficiency, saving in materials and low production cost.
Description
Technical field
The utility model relates to a kind of high-voltage motor terminal box, relates in particular to a kind of pressure relief of high-voltage motor terminal box.
Background technology
At present, high-voltage motor is used in large-scale factories and miness widely, sees also illustrated in figures 1 and 2ly, and Fig. 1 is the front view of traditional high-voltage motor terminal box pressure relief, and Fig. 2 is the profile of traditional high-voltage motor terminal box pressure relief.The terminal box pressure relief of traditional high-voltage motor all is to adopt a very thin cover plate 10 to cover pressure relief opening; Utilize pressing plate 11 and set bolt 12 to be fixed on the terminal box 13 then; And between pressing plate 11 and the cover plate 10 sealing gasket 14 is set, when the pressure in the terminal box 13 was excessive, cover plate 10 was just washed open; Play the effect of pressure release, there is following shortcoming in this pressure release form:
1) structure more complicated and heaviness need a plurality of parts of cover plate, pressing plate and set bolt, give to produce to assemble and bring inconvenience, and production cost is higher;
2) the required operation of processing is more in the production process, and man-hour is many, and production efficiency is low.
The utility model content
The purpose of the utility model is to provide a kind of high-voltage motor terminal box pressure relief, its have simple in structure, be easy to realize, characteristics that production cost is low and safe and reliable, to solve the problem that prior art mesohigh connection box for motor pressure relief exists.
For reaching this purpose, the utility model adopts following technical scheme:
A kind of high-voltage motor terminal box pressure relief, it comprises junction box seat, wherein, offers several relief holes on the said junction box seat, the elastomeric element that overvoltage is ejected is installed in sealing on the said relief hole.
Especially, said relief hole is a strip, and it offers number is two.
Especially, said relief hole arranged crosswise.
Especially, said relief hole is arranged in parallel.
Especially, said elastomeric element is the rubber tent, and the both sides height of said rubber tent is greater than the width of relief hole, so that the sidewall of junction box seat can be nested on the rubber tent.
The beneficial effect of the utility model does, said high-voltage motor terminal box pressure relief is when pressure is excessive, and the rubber tent will be flicked; Compared with prior art there is not complicated structure such as cover plate, pressing plate, sealing gasket; Simple in structure, saved the man-hour of processing and assembling, improved production efficiency; And practiced thrift material, production cost is low.
Description of drawings
Fig. 1 is the front view of traditional high-voltage motor terminal box pressure relief;
Fig. 2 is the profile of traditional high-voltage motor terminal box pressure relief;
The front view of the high-voltage motor terminal box pressure relief that Fig. 3 provides for the utility model embodiment 1;
The profile of the high-voltage motor terminal box pressure relief that Fig. 4 provides for the utility model embodiment 1.
Embodiment
Further specify the technical scheme of the utility model below in conjunction with accompanying drawing and through embodiment.
See also Fig. 3 and shown in Figure 4, the front view of the high-voltage motor terminal box pressure relief that Fig. 3 provides for the utility model embodiment 1; The profile of the high-voltage motor terminal box pressure relief that Fig. 4 provides for the utility model embodiment 1.
In the present embodiment; A kind of high-voltage motor terminal box pressure relief comprises junction box seat 20; Offer the relief hole 21 of two strip arranged crosswise on the said junction box seat 20; The rubber tent 22 that overvoltage is ejected is installed in sealing on the said relief hole 21, and the both sides height of said rubber tent 22 is greater than the width of relief hole 21, so that the sidewall of junction box seat 20 can be nested on the rubber tent 22.
When the pressure in the high-voltage motor terminal box is excessive, will certainly produce pressure to rubber tent 22, rubber tent 22 will be flicked under the effect of this pressure, reaches the pressure release purpose.
Above-mentioned high-voltage motor terminal box pressure relief has been simplified pressure relief when reaching the pressure release effect, reduced production cost, has improved production efficiency.
