Summary of the invention
The objective of the invention is to overcome the deficiencies in the prior art, provide joint and the mode of connection thereof of a kind of electric machine with aluminium winding aluminum steel lead-in wire with the copper cash lead-in wire, protection and the anti-oxidation of the head that achieves a butt joint.
The present invention is achieved by the following technical solutions, the present invention includes aluminum steel lead-in wire, copper cash lead-in wire, heat-shrinkable T bush and seven tooth pressure contact pin; Described heat-shrinkable T bush one end opening, other end sealing, the bare wire part of described aluminum steel lead-in wire and the bare wire of copper cash lead-in wire partly are intertwined, and seven tooth pressure contact pin are pressed on the wire harness of winding, and the wound portion branch of seven tooth pressure contact pin, aluminum steel lead-in wire and copper cash lead-in wire is arranged in the heat-shrinkable T bush.
A kind of electric machine with aluminium winding aluminum steel lead-in wire and the mode of connection that copper cash goes between may further comprise the steps:
(1) head 30～40mm peeling of aluminium enamel-covered wire is handled, the bare wire part of the aluminum steel lead-in wire after the peeling and the bare wire of copper cash lead-in wire partly are intertwined;
(2) use seven tooth pressure contact pin the wire harness of aluminum steel lead-in wire and the winding of copper cash lead-in wire to be compressed the head excision that has more;
(3) heat-shrinkable T bush with end sealing is socketed on the wire harness of the good winding of crimping;
(4) with air-heater heat-shrinkable T bush is heated, the heat-shrinkable T bush after-tack of being heated is fixed on the wire harness of winding.
Heat-shrinkable T bush socket for convenience, in the described step (1), the coiling length of the bare wire part of aluminum steel lead-in wire and the bare wire part of copper cash lead-in wire is 10～15mm.
In the described step (3), the heat resisting temperature of heat-shrinkable T bush is 130～170 ℃.Can below 100 ℃ with the heat-shrinkable T bush thermoplastic.
The present invention has the following advantages compared to existing technology: the invention enables electric machine with aluminium winding lead-out wire and copper cash lead-out wire attended operation method simple, can well aluminum steel, copper cash lead-out wire be connected, the aluminum steel joint is difficult for loosening and oxidation, ensure electrical machine insulation, space requirement to motor simultaneously reduces, and can realize wiring in less space.Use the cold treatment wiring, anti-oxidation improves fail safe, uses seven tooth pressure contact pin not only can connect two kinds of different lines simultaneously, also can connect the coiling the end of a thread that breaks, and uses more extensive.
