Connector and connection method for aluminum conductor leads of aluminum conductor machine and copper conductor leads

Abstract

The invention discloses a connector and a connection method for aluminum conductor leads of an aluminum conductor machine and copper conductor leads. The connector is characterized in that one end of each heat shrink sleeve is open, and the other end of each heat shrink sleeve is sealed. The connection method includes winding bare wire portions of the aluminum conductor leads with bare wire portions of the copper conductor leads, pressing seven-tooth crimping plates on wound wire harnesses, and arranging wound portions of the seven-tooth crimping plates, the aluminum conductor leads and the copper conductor leads in the heat shrink sleeves; peeling heads of aluminum enameled wires and then winding the aluminum enameled wires with the copper conductor leads after the heads of the aluminum enameled wires are peeled; compressing the wound wire harnesses by the seven-tooth crimping plates and cutting off redundant heads of the wound wire harnesses; sleeving each heat shrink sleeve with the sealed end on the corresponding crimped wound wire harness; heating the heat shrink sleeves so that the heat shrink sleeves can be softened and fixed onto the wound wire harnesses. The connector and the connection method have the advantages that operation for connecting the leads of the aluminum conductor machine with the copper conductor leads is simple, joints of the aluminum conductors are not easy to loose or oxidize, the machine is insulated assuredly, spatial requirements on the machine are reduced, and connection can be performed on the machine in small space.

Description

technical field [0001] The invention relates to a wiring method for a semi-aluminum or all-aluminum motor lead wire and a copper wire socket part, in particular to a joint between an aluminum wire lead wire and a copper wire lead wire of an aluminum wire motor and a wiring method thereof. Background technique [0002] At present, there are two ways to wire the aluminum wire motor of the refrigerator compressor. A process of using ordinary copper wire motor solder and flux to weld the lead wires of aluminum wires and copper wires, and then immerse the welded joints in hot melt adhesive at a temperature of about 100 ° C to 120 ° C. About 45 seconds to 70 seconds to fully combine the hot melt adhesive and the joint, so as to isolate the joint from the outside world and strengthen the tight connection between the aluminum wire and the copper wire, and then add a heat-resistant 130°C to 170°C heat outside. Shrink the sleeve to make the joint fixed and formed; using this method, ...

Problems solved by technology

This method has strict requirements on the placement of aluminum wires and copper wires before crimping, which is cumbersome to operate and affects production efficiency; the stator dipping paint can have an insulating effect, and special equipment needs to be invested, and the safe creepage distance between the motor and adjacent metal parts is sufficient In the case of motor impregnation increases the cost
