What is an automotive high voltage connector? What are its uses?

Introduction to the types of high-voltage connectors:

The high-voltage connector for new energy vehicles is an electromechanical integration product, which is mainly composed of four parts: contacts, insulators, shells and accessories. It can complete the connection of optical and electrical signals required by the vehicle in driving; the insulator and the shell mainly play the role of fixation, insulation and mechanical protection. The manufacturing process integrates multiple technologies such as electrical performance design, CNC machining, stamping technology, plastic pressing technology, precision die-casting technology, and strict testing methods. Since the quality and accuracy of high-voltage connector products directly affect the electrical, mechanical, environmental and other performance of the connector, and thus affect the driving safety of electric vehicles, the quality requirements and manufacturing accuracy of high-voltage connectors are relatively high, which belongs to the additional field of connectors. High-value mid-to-high-end products. We can often see various high-voltage connectors on the whole vehicle. The structure of high-voltage connectors generally includes: contact pair, sealing ring, butt locking mechanism, bracket, shell, positioning mechanism, high-voltage interlocking mechanism, shielding mechanism, Insulation structure, etc. The general termination methods include welding, crimping, through-hole connection, screw connection, etc. There are also various installation methods, including panel type, cable type, nut type, through-wall type, etc. Among them, the connection method of the wiring harness is different: it is mainly divided into two types of connections: one is the fixed type that is directly connected by bolts; One is a plug-in connection. Use with the high-voltage cables of the specified specifications to achieve the effect.

Bolt connection: It is a kind of connection that we often see on the whole vehicle. The advantage of this method lies in its connection reliability. The mechanical force of the bolt can resist the influence of automobile-level vibration, and its cost is relatively low. Of course, its inconvenience is that the bolt connection requires a certain amount of operation and installation space. For the more platform-oriented and more reasonable interior space of the area, it is impossible to leave too much installation space, and from batch operation and It is also not suitable from the perspective of after-sales maintenance, and the more bolts there are, the greater the risk of human error, so it also has its limitations; we often see similar products on early Japanese-American hybrid models, and of course now in some We can still see many similar connections for the three-phase motor lines of passenger cars and the battery power input and output lines of some commercial vehicles. Such connections generally require external boxes to achieve protection and other functional requirements, so whether to use this kind of connection The method needs to be combined with after-sales requirements from the perspective of the design and layout of the power line of the whole vehicle.
