Introduction to the technological development of automotive connectors through the ages

The development of automotive connectors and the development of electric vehicles is synchronized, from the connector point of view, the domestic electric vehicle connecting machine development history of the following generations.1) The first generation of automotive connectors (Figure 1), started in 2008 or so, mainly by the time of the industrial connector modification. The characteristics of this generation of products, mainly metal even shell, no high-voltage interlock function, anti-error access (anti-dull) effect is poor.

(2) The 2nd generation of automotive connectors (Figure 2), on the basis of the 1st generation added a high-voltage interlock function, the connector shell is gradually changed from metal to plastic.

(3) The third generation of automotive connectors (Figure 3), plastic + shielding function + high-voltage interlocking automotive connectors. Representative of the work of the 800 series products (these products are operated by the second to complete part of the second level of unlocking function, not a direct mechanical structure).

(4) The 4th generation of automotive connectors (Figure 4), plastic + shielding function + high-voltage interlocking + secondary unlocking of the automotive connector. Representative of the work of 280 series products, such as TE / Chi green and a new generation of domestic products, these products are through the mechanical structure to complete the secondary unlock function, more secure.

(5) The future of a new generation of automotive connectors (Figure 5) will be in the 4th generation of products to consider cooling methods, such as synergistic high-power charging with liquid cooling, air-cooled approach, to help improve the transmission of energy density, reduce the weight, enhance the general function of the product.
