Abstract
The utility module relates to an insulator explosion-proof motor junction box, which is provided with a box seat and a box cover. The box seat and the box cover are both thin-wall metal plate structures and connected via riveting bolts, a sealing strip with the arc section is mounted at the joint of the box seat and the box cover, a connecting plate with a spigot is welded at the bottom of the box seat, a sealing strip with circular section is mounted at the spigot of the connecting plate, the connecting plate is provided with an insulator consisting of an insulation base and a connecting bolt, the connecting plate is provided with three threading holes, three-phase internal wires respectively penetrate through the threading holes to be connected with the connecting bolt, and external cables are led into an inner cavity of the junction box to be connected with the connecting bolt of the insulator. The junction box is reasonable in integral structure arrangement, compact in structure, attractive in appearance, light in weight, low in material consumption and fine in sealing effect, sealing links are reduced while sealing reliability is increased, and simultaneously service safety reliability is strengthened greatly by aids of a rupture disc and drain holes which are additionally arranged in the junction box.
Description
Technical field
The utility model belongs to motor appurtenances technical field, is a kind of insulator style fire-proof motor terminal box.
Background technology
In technique known, the fire-proof motor terminal box, its junction box seat adopts steel plate to be welded usually, between junction box seat and the connector cover and the connecting portion of cassette holder and motor all adopt flat seal bar sealing, and on sealing strip, be drilled with installing hole, junction box seat and connecting plate are two body structures, there is following defective in this terminal box: the one, and the structure heaviness, profile is coarse, not only influence the outward appearance of terminal box, and consumable material is many; The 2nd, sealing part is many, and sealing effectiveness is poor, makes also inconvenient; The 3rd, the easy ponding of terminal box, there is short circuit risk in the wiring position; The 4th, there is not unloading pressure means, when the terminal box internal pressure is excessive, the damage of blasting easily; The 5th, lead wire SI semi-insulation weak effect often causes machine halt trouble.
The utility model content
The purpose of this utility model provides a kind of reasonable in design, in light weight, good sealing effect, and can reduce the insulator style fire-proof motor terminal box of manufacturing cost.
Realize that the technical scheme that the purpose of this utility model is taked is: this terminal box has the cassette holder and the lid of thin-walled sheet metal structural, adopt the riveted joint bolt to be connected between cassette holder and the lid, the sealing strip that the cross section is an arc is equipped with in its junction, the cassette holder bottom is welded with the connecting plate of band seam, the seam position of this connecting plate is equipped with the cross section and is circular sealing strip, connecting plate is provided with insulator, insulator is made up of insulating base and connection bolt, connecting plate is provided with 3 through wires holes, 3 phase back panel wirings pass this through wires hole respectively and are connected with connection bolt, and the external electric cable is introduced the terminal box inner chamber and is connected with the connection bolt of insulator.
The upper inner of described cassette holder is provided with the sealing side plate.
Described junction box seat bottom is provided with rupture disk and osculum, and protective cover is equipped with in the outside of rupture disk.
Insulator style fire-proof motor terminal box according to such scheme is made because of adopting the thin-walled sheet metal structural, makes that the overall structure of terminal box is not only rationally distributed, and compact conformation, good looking appearance and in light weight are economized on material.In addition, between the cassette holder of terminal box and the lid and the faying face between cassette holder and the connecting plate for electric motor to adopt the cross section be arc or circular sealing strip, and by fashion of extrusion sealing with sealing side plate and riveted joint bolt, not only reduced sealing part, and increased the reliability that seals, reached the purpose of good sealing effect.Simultaneously in junction box body, increase rupture disk, strengthened the security reliability of using greatly.This terminal box is applicable to middle and small motor.
