The utility model is realized through following technical scheme:
Above-mentioned a kind of electric automobile high voltage distribution box comprises box body, and said box body comprises casing and loam cake; Be provided with seal washer between said casing and the said loam cake.Said seal washer is fixedly connected with casing with said loam cake respectively through screw.
Said electric automobile high voltage distribution box, wherein: said box body also includes mounting bracket, and said mounting bracket is installed in the two opposite outer wall of said casing.
Said electric automobile high voltage distribution box, wherein: said block terminal also comprises the connector of being located at said box body and the contactor that is electrically connected with said connector, preliminary filling resistance and fuse.
Said electric automobile high voltage distribution box, wherein: be equiped with connecting plate on the said casing inner bottom surface, it is central that said preliminary filling resistance is installed in said connecting plate.
Said electric automobile high voltage distribution box, wherein: said connector comprises plug end, the outward extending assembling block of plug wire end and middle part; Said plug end protrudes out said casing lateral wall; Said plug wire end protrudes out said box inside wall; Said assembling block is connected fixing with said casing lateral wall.
Said electric automobile high voltage distribution box, wherein: said block terminal also is provided with air switch, and said air switch is electrically connected with said fuse, contactor and preliminary filling resistance respectively.
Said electric automobile high voltage distribution box, wherein: the middle part of said loam cake is provided with the air switch lid.
Beneficial effect:
The utility model is simple in structure, firm; Each components and parts distributes compact, and reliable, high pressure resistant, the anti-current switching ability of circuit is strong and excellent in durability, especially between loam cake and casing, fixes with the sealing gasket sealing and with screw; Install simple and be convenient to repair demolition; Not only convenient and practical, also significantly promoted the waterproof of electric automobile high voltage distribution box and the rank of sealing, in use safer.
