Angled multi-core connectors for motors and motor controllers

Abstract

The invention discloses a multi-core angle connector for a motor and a motor controller. The multi-core angle connector comprises a shell, an insulation mounting plate, soft copper bars, terminal blocks, insulators, shielding rings, shielding pressure sleeves, a cover plate, a seal gasket and a seal ring. When cables are connected into the connector, the cables are stripped to exposure shielding layers and then connected with the terminal blocks, and the shielding rings are connected to the cables through the shielding pressure sleeves by pressing and clamped on the shell; the insulators sleeve the terminal blocks and pressed into the shell by interference fit; the insulation mounting plate is detachably fixed to the shell; the soft copper bars and the terminal blocks are detachably fixed to the insulation mounting plate; the seal gasket is arranged between the shell and the cover plate; the seal ring is arranged on a mounting surface of the shell. The multi-core angle connector has advantages that product integration is realized, and secondary shielding processing is reduced; a power part is locally bendable, the defect that the copper bars are not coplanar due to tolerance accumulation is improved, effective contact of joint faces of the copper bars is guaranteed, and accordingly high reliability in connection is realized.

Description

technical field [0001] The invention relates to the technical field of electric vehicle connectors, in particular to a bent multi-core connector for electric vehicle motors and motor controllers. Background technique [0002] Usually, the motor wires are routed at 180°, but in the actual wiring process, the motor wires need to be bent (even 90°), and the bending position is the stress concentration point. During the thermal expansion and cold contraction of the cable, the rubber may crack, which poses a safety hazard. , in order to meet this requirement, it is necessary to design a 90° outlet structure. Existing motors and motor controllers mainly use cable crimping copper tube terminals or hard copper bars to achieve electrical connection. In order to achieve shielding effect, the former mainly uses shielded pipe joints or shielded lead wires for grounding, and the latter is designed with a corresponding shielding structure. , so each has its own defects. The former cannot...

[0002] Usually, the motor wires are routed at 180°, but in the actual wiring process, the motor wires need to be bent (even 90°), and the bending position is the stress concentration point. During the thermal expansion and cold contraction of the cable, the rubber may crack, which poses a safety hazard. , in order to meet this requirement, it is necessary to design a 90° outlet structure

Existing motors and motor controllers mainly use cable crimping copper tube terminals or hard copper bars to achieve electrical connection. In order to achieve shielding effect, the former mainly uses shielded pipe joints or shielded lead wires for grounding, and the latter is designed with a corresponding shielding structure. , so each has its own defects. The former is unable to achieve integration, and the latter is designed to lead out at 90°. There will be cumulative tolerances in multi-core power components, resulting in power components that are not on the same mounting surface, difficult to assemble, and low in efficiency.
