Embodiment Construction

[0016] The present invention will be further described below in conjunction with the accompanying drawings.

[0017] Such as figure 1 and figure 2 As shown, the insulation wrapping process of the motor winding lead wire joint includes filling with silicone rubber insulating mud, filling with sealant, and insulating wrapping.

[0018] First, silicone rubber insulating mud filling: After the cable joint 1 is welded, clean the welding part, the cable joint and the cable crimping section 3, etc., and cut an appropriate amount of silicone rubber insulating mud to fill in the following two welding laps Groove steps generated: cable joint 1 and cable 2 bare conductor groove and cable joint 1 and lead wire joint overlap groove, it is required that the silicone rubber insulating mud filled in the above two places should not exceed the joint plane, and the transition should be smooth to avoid lapping The location is too thick after subsequent insulation dressing.

[0019] Second, se...

Abstract

The invention relates to an insulation bandaging process of an electric motor winding lead wire connector. The insulation bandaging process of the electric motor winding lead wire connector comprises a silicon rubber insulation mud filling, a sealant filling and an insulation bandaging. The silicon rubber insulation mud is used for filling groove steps produced through welding and overlap joint after welding the lead wire connector, and then the sealant is used for strengthening filling, bare parts without insulating layers in a welding area are wholly outer packed by half folding a self-adhesion type silicon rubber tape and a double glass mica powder center rubber tape 5446-2 three times, and half folding a polyester heat contraction band one time. Through the insulation bandaging process, the insulation bandaging process of the electric motor winding lead wire connector enables the electric motor winding lead wire connector welding position to be good in integral insulation property and waterproof property, capable of avoiding insulation weak spots and suitable for insulation bandaging of the electric motor winding lead wire connector.

Description

technical field [0001] The invention relates to a motor manufacturing process, in particular to an insulation wrapping process for a lead wire joint of a motor winding. Background technique [0002] After welding, the exposed parts of the motor winding lead wire joints are insulated and bandaged, which often has the following problems: there are weak points in the insulation of the welded parts after the insulation bandage, and the overall waterproof performance is poor, which will bring certain hidden dangers to the quality of the product.
