Enameled wire and wire compact connector and method

Abstract

The invention provides an enameled wire and wire compact connector and method. The connector is composed of two cylindrical structures with axial through holes. The axial through hole axes of the two cylindrical structures are parallel to each other, the two cylindrical structures have a partial overlapping area in the axial direction, the two cylindrical structures are integrally connected together in the overlapping area, and the connecting part can bear current needing to be borne by the connector; the axial through hole of the first cylindrical structure is matched with the enameled wire, electric connection between the enameled wire and the connector can be achieved in a brazing mode, the axial through hole of the second cylindrical structure is matched with the end of the multi-core wire subjected to head stripping processing, and electric connection between the multi-core wire and the connector can be achieved in a crimping mode. By using the connector, the problem of tin climbing of the multi-core wire during welding of the enameled wire can be avoided, and a connection node of the enameled wire and the multi-core wire can be regular in shape and compact in structure, so that insulation and binding treatment can be carried out at the narrow end part of the motor winding.

Description

technical field [0001] The invention belongs to the technical field of wire connection in the technical field of motors, and specifically relates to a compact connector and method for an enameled wire and a wire. Background technique [0002] In today's motor industry, for a motor structure with a junction box, the winding enameled wire is usually directly connected to the junction board on the junction box, so that the user can connect the power supply to the junction box. However, for motor wiring structures without a junction box or where the junction box cannot be directly connected to the enameled wire, it is usually necessary to remove the paint from the end of the winding enameled wire and then twist and twist with the multi-core wire core before brazing. Due to the capillary phenomenon of the inner core of the multi-core wire during soldering, when the wire core encounters solder during brazing, the molten solder will penetrate into the wire along the multi-strand wi...

AI Technical Summary

Problems solved by technology

This tin creeping phenomenon will lead to a serious reduction in the flexibility of the multi-core wire end

For the narrow space inside the micro motor, the wire with reduced flexibility makes it difficult to shape and bind the end of the motor winding

At the same time, the method of winding enameled wire and multi-core wire and then brazing is still mainly relying on the manual operation of the operator, so the connection quality of the motor wire also varies with the operator's method.

In addition, there will be a twisted node knot in the twisted part where the shape and size cannot be precisely controlled

For the narrow space at the end of the winding end of the micro-motor with compact structure, this node bump seriously affects the shaping of the end of the motor winding and the reliability of the end insulation
