Connector assembly and processing method

Abstract

The connector assembly comprises an electric connection framework and a connector connected with the two ends of the electric connection framework, the connector comprises connection terminals, an outer shell and an inner shell which is arranged in the outer shell and has shielding effectiveness, the two ends of the electric connection framework are electrically connected with the connection terminals respectively, and the inner shell is arranged in the outer shell. The periphery of the electric connection framework is coated with an insulating layer and a shielding layer from inside to outside, the shielding layer is electrically connected with the inner shell, the inner shell is made of conductive plastic, and the outer shell and the inner shell are fixed to part of the connection terminals and part of the electric connection framework in an integrated forming mode. The electric connection framework is used for replacing a multi-core copper cable, the diameter of the cable is reduced, the weight of the cable is reduced, the cable is convenient to install, friction between the cable and a vehicle shell is reduced, and the service life of the connector is prolonged. The outer shell and the inner shell are fixed on a part of the connecting terminals and a part of the electric connecting framework in an integrated forming manner, so that the processing is convenient, the product weight is reduced, the waterproof sealing effect of the connector can be ensured, and the production cost of the connector is reduced.

Description

technical field [0001] The invention relates to the technical field of automotive electrical appliances, and more particularly, to a connector assembly and a processing method. Background technique [0002] With the increasing popularity of new energy vehicles, the equipment and facilities for electrical connection of new energy vehicles have also developed. The connector assemblies on new energy vehicles have to meet the requirements of high current, and the on-current is relatively large. The diameter of the cable on the connector assembly also increases. At present, most of the cables on the connector assembly use multi-core copper cables, which are heavy and expensive, which have become obstacles restricting the popularization of new energy vehicles. In addition, although the multi-core cable is relatively soft, it can be easily processed and wired. Due to the thick wire diameter and heavy weight, the cable will frequently rub against the car shell during the driving pr...

Problems solved by technology

At present, most of the cables on the connector assembly use multi-core copper cables, which are heavy and expensive, which has become an obstacle restricting the popularization of new energy vehicles.

In addition, although the multi-core cable is relatively soft, it can be processed and routed easily. Due to the thick wire diameter and heavy weight, the cable will frequently rub against the car shell during driving, resulting in damage to the insulation layer of the cable and causing high voltage. Discharge may damage the vehicle in light cases, or cause serious traffic accidents in severe cases.

[0003] In order to reduce the influence of electromagnetic interference, conductive cables usually use shielding nets for electromagnetic interference shielding. At present, the commonly used shielding nets are made of metal wires. It is necessary to add shielding braiding machines to the cable production equipment. The equipment price is high, accounting for Large land area leads to high price of shielded cables for connectors
