Selectable, described binding post places in the described housing, and an end of described binding post cooperates with described housing inner face, and the other end of described binding post cooperates with internal circlip.
Selectable, described three phase mains input interface also has jump ring, and described jump ring tightens described binding post.
Selectable, have insulation cushion between described connector and described conduit bushing housing.
Selectable, described line outlet place has pressing plate, and described pressing plate compresses described sealing plug and fixes with described conduit bushing housing.
Selectable, described three phase mains input interface is positioned at the top of compressor.
The beneficial effects of the utility model:
The hermetically-sealed construction that adopts the three phase mains input interface to cooperate with conduit bushing, the lead of compressor inside is connected with binding post, and outside lead is connected with connector, and connector is connected with binding post, has therefore realized the conducting of circuit.
Further, the sealing gasket that increases between housing and the conduit bushing housing makes the junction good seal.
Further, binding post is fastened in the conduit bushing housing by housing inner face and shaft block ring, and binding post is installed firmly, is difficult for loosening.
Further, it is tightr that jump ring is fitted binding post and conduit bushing, cooperates firmly.
Further, insulation cushion has strengthened the insulating properties of conduit bushing integral body.
Further, pressing plate can prevent that sealing plug from moving axially, and makes the sealing of conduit bushing more reliable.
Further, compressor three phase mains input interface is placed the compressor top, the below of terminal is a cavity, refrigeration oil and deposit of moisture were in the compressor inner bottom part after compressor left standstill, because it is limited to enter into the refrigerant charge of compressor suction port, it highly can not reach the motor lead-out wire position of binding post below, can effectively avoid cold-producing medium to the corrosion of motor lead-out wire, and the class of insulation of compressor is raise.
