The function of electric arc of going out will be extinguished, therefore the heat dissipating layer not only has so if cable connector generates electric arc by quartz sand
The function of height heat dissipation, also has the function of arc protection.
Preferably, the shell includes the upper cover and lower cover being detachably connected, and is set respectively in the upper cover and lower cover
It is equipped with more than one relief hole.Relief hole plays the use let out except energy in electric cable explosion, while being also used as being vented
Mouthful.
Preferably, the upper cover and lower cover are semicylinder, the upper cover and lower cover snapping.The upper cover of shell and
Lower cover is detachably connected the disassembly, it can be achieved that joint protection box, convenient for the maintenance to cable connector.Upper cover two sides are equipped with convex
The built-in edges risen, the built-in edges that lower cover two sides correspond to upper cover two sides are equipped with groove, and upper cover is embedded in lower cover two by the built-in edges of two sides
In the groove of side, fastening forms complete shell.
Preferably, the shell is made of stainless steel material, the shell with a thickness of 1-1.5mm.
The beneficial effects of the utility model are: the utility model proposes radiating explosion-proof preventing arc joint protection box, needle
To cable connector in installation and use common security risk and design, setting low resistance highly heat-conductive material made of heat dissipation
Layer, enables the heat of cable to come out in time, and can extinguish electric arc, therefore there is explosion-proof, high heat dissipation and arc protection etc.
Excellent performance.
