Abstract
The utility model relates to a kind of flame proof cable terminal, and this flame proof cable terminal one end is connected with main switch bus contact in flameproof cabinet inside, and the other end connects adjacent switch equipment or aerial cable inlet wire outside; Explosion-insulating through wall bursting diaphragm and explosion-insulating through wall conducting rod pass through together with poured with epoxy resin; It is external that this explosion-insulating through wall bursting diaphragm is placed on epoxy resin, and explosion-insulating through wall bursting diaphragm is between epoxy resin flange face and flame proof stainless steel casing; Explosion-insulating through wall bursting diaphragm and flame proof stainless steel casing are fixed by copper sheathing, and this copper sheathing is also through explosion-insulating through wall bursting diaphragm and epoxy resin flange face.The beneficial effects of the utility model are: when inside electric appliance is blasted for some reason, because explosion-insulating through wall bursting diaphragm is brass material, the spray process of letting out can make high-temperature gas or flame obtain enough coolings, make it the explosive gas mixture can not lighting surrounding, also would not cause adjacent cabinet or extraneous explosion, thus play the effect of flame proof.
Description
Technical field
The utility model belongs to flame-proof electric equipment technical field, particularly relate to a kind of be applicable to the requirement of explosion proof high field such as mine, Gas Wells, gas station flame proof cable terminal.
Background technology
In the environment such as coal mine gas and coal dust explosive, the electric spark of electric product, electric arc, overheated etc. all may set off an explosion, and therefore, must adopt flame-proof electric equipment at this environment.When inside electric appliance is blasted for some reason due to the effect of shell, by explosive range restriction in the enclosure, and the energy shortage of blast is with the explosive gas of housing exterior of igniting or coal dust, to play the effect of flame proof.
Summary of the invention
The purpose of this utility model is the deficiency overcoming prior art existence, and provides a kind of flame proof cable terminal playing flame proof effect.
The purpose of this utility model has been come by following technical solution.This flame proof cable terminal, this flame proof cable terminal one end is connected with main switch bus contact in flameproof cabinet inside, and the other end connects adjacent switch equipment or aerial cable inlet wire outside; This flame proof cable terminal comprises explosion-insulating through wall bursting diaphragm, explosion-insulating through wall conducting rod and flame proof stainless steel casing, and described explosion-insulating through wall bursting diaphragm and explosion-insulating through wall conducting rod pass through together with poured with epoxy resin; It is external that this explosion-insulating through wall bursting diaphragm is placed on epoxy resin, and explosion-insulating through wall bursting diaphragm is between epoxy resin flange face and flame proof stainless steel casing; Explosion-insulating through wall bursting diaphragm and flame proof stainless steel casing are fixed by copper sheathing, and this copper sheathing is also through explosion-insulating through wall bursting diaphragm and epoxy resin flange face, and four holes that copper sheathing and explosion-insulating through wall bursting diaphragm are offered adopt interference fit to fix.
As preferably, the structure of described explosion-insulating through wall bursting diaphragm is square flange face structure, is made by brass material.
As preferably, described explosion-insulating through wall bursting diaphragm and the contact-making surface of epoxy resin body and epoxy resin flange face make blasting treatment layer.
The beneficial effects of the utility model are: when inside electric appliance is blasted for some reason, because explosion-insulating through wall bursting diaphragm is brass material, the spray process of letting out can make high-temperature gas or flame obtain enough coolings, make it the explosive gas mixture can not lighting surrounding, also would not cause adjacent cabinet or extraneous explosion, thus play the effect of flame proof.
Accompanying drawing explanation
Fig. 1 is main TV structure schematic diagram of the present utility model.
Fig. 2 is explosion-insulating through wall bursting diaphragm structural representation of the present utility model.
Label in accompanying drawing is respectively: 1, epoxy resin body; 2, explosion-insulating through wall bursting diaphragm; 3, explosion-insulating through wall conducting rod; 4, copper sheathing; 5, flame proof stainless steel casing; 6, epoxy resin flange face; 21, hole.
Embodiment
Below in conjunction with accompanying drawing, detailed introduction is done to the utility model: as shown in accompanying drawing 1,2, flame proof cable terminal one end of the present utility model is connected with main switch bus contact in flameproof cabinet inside, and the other end connects adjacent switch equipment or aerial cable inlet wire outside; This flame proof cable terminal comprises explosion-insulating through wall bursting diaphragm 2, explosion-insulating through wall conducting rod 3 and flame proof stainless steel casing 5, and described explosion-insulating through wall bursting diaphragm 2 and explosion-insulating through wall conducting rod 3 pass through together with poured with epoxy resin; This explosion-insulating through wall bursting diaphragm 2 is placed on outside epoxy resin body 1, and explosion-insulating through wall bursting diaphragm 2 is between epoxy resin flange face 6 and flame proof stainless steel casing 5; Explosion-insulating through wall bursting diaphragm 2 is fixed by copper sheathing 4 with flame proof stainless steel casing 5, this copper sheathing 4 is also through explosion-insulating through wall bursting diaphragm 2 and epoxy resin flange face 6, and four holes 21 that copper sheathing 4 and explosion-insulating through wall bursting diaphragm 2 are offered adopt interference fit to fix, strengthen the engaging force of explosion-insulating through wall bursting diaphragm 2 and epoxy resin flange face 6 with four limit tractives.
The structure of described explosion-insulating through wall bursting diaphragm 2 is square flange face structure, is made by brass material.
Described explosion-insulating through wall bursting diaphragm 2 and the contact-making surface of epoxy resin body 1 and epoxy resin flange face 6 make sand blasting process, for ensureing the engaging force of explosion-insulating through wall bursting diaphragm 2 and epoxy resin body 1 and epoxy resin flange face 6.
The utility model flameproof principle is as follows: the high-temperature gas of the explosive gas mixture explosion time generation of switch internal or flame, outwards sprayed by the gap (between explosion-insulating through wall bursting diaphragm 2 and flame proof stainless steel casing 5 gap) on the composition surface of flame proof cable terminal and flame proof stainless steel casing 5 and let out, because explosion-insulating through wall bursting diaphragm 2 is brass materials, the spray process of letting out can make high-temperature gas or flame obtain enough coolings, make it the explosive gas mixture can not lighting surrounding, also would not cause adjacent cabinet or extraneous explosion, thus play the effect of flame proof.
The utility model is not limited to above-mentioned execution mode; no matter do any change on its shape or material are formed; every employing structural design provided by the utility model, is all one distortion of the present utility model, all should thinks within the utility model protection range.
