Abstract
Provided is an increased safety explosion-proof junction box structure, comprising a cover plate cover plate and a box body. A support plate is disposed in the box body. U-phase copper bars, V-phase copper bars, and W-phase copper bars are arranged in a stair-step shape and are fixed on the support plate through fasteners. Insulating plates are disposed among the U-phase copper bars, the V-phase copper bars, and the W-phase copper bars. The U-phase copper bars, the V-phase copper bars, and the W-phase copper bars are configured in the stair-step shape, so connecting operation of an external power line and a wiring copper busbar is convenient. A weak current circuit is disposed through a wiring channel, preventing the weak current circuit from being damaged caused by scratch. A grid plate of the explosion-proof junction box structure is added with comb-shaped reeds, contacts between the box body and the cover plate are increased, contact resistance between the grid plate and the cover plate is reduced, thereby enhancing shielding effect.
Description
Technical field
The utility model belongs to technical field of motors, relates to a kind of INCREASEDSAFETY anti-explosion terminal box structure.
