The solution to the contact structure of high current customized High voltage connector supplier china in motor control, motor drive and other parts of electric vehicles and hybrid electric vehicles is to adopt the double spiral structure, with a contact area of 65%, low insertion force and high reliability, a working voltage of 630 V, a rated current of 455 a, a relatively high overload capacity, and a mechanical life of more than 500 times. It is one of the popular internal contact structures in the field of customized High voltage connector supplier china for electric vehicles.

There is a developed porous wear-resistant inner contact ring for customized High voltage connector supplier china of electric vehicle, including porous elastic inner contact ring and surface coating. The porous elastic contact ring is a high elastic copper nickel silicon alloy open tube with a wall thickness of 0.5 mm, an inner diameter of 8 mm and a length of 19 mm. The pipe is arc-shaped and concave in the middle with an inner diameter of 5mm. Holes with a diameter of 1.5 mm are evenly distributed on the pipe wall in a staggered manner. There is a seam along the axis of the pipe, and the seam width is controlled within 0.5 mm. The surface coating is one of AgCu, AGSB, AgPd and AuAg alloys, with a thickness of 0.5~2.0 μ S. The content of Cu in AgCu alloy coating is 1%~2%; The content of sb in AGSB alloy coating is 1.5%~2.5%; The content of PD in AgPd alloy coating is 8%~10%; The content of Ag in AuAg alloy coating is 30%~40%. The alloy coating can be obtained by electroplating or magnetron sputtering.

The high-voltage connector has simple contact structure, reliable performance and wide application range, and can effectively promote the application of customized High voltage connector supplier china; The porous wear-resistant elastic inner contact ring realizes the mesh linear contact with the plug, and the contact resistance is low, meeting the contact resistance requirements of lv215 high voltage connector

The elastic jack contact is composed of a sheath, an elastic part and a jack. The elastic contact is bent by an elastic wire or an elastic strip into a shape including an arc-shaped contact part and a hook shaped fixed part. It is evenly arranged around the circumference of the jack. The arc-shaped contact part is suspended towards the center of the jack to form a sliding fulcrum, and an internal contact jack is formed in the radial direction of the jack. The structure has the advantages of simple structure, low plugging force and large current carrying capacity.

Recently, there is a contact type elastic internal contact structure of electric vehicle customized High voltage connector supplier china, which comprises an elastic contact ring, a cylindrical contact head and a socket body. The elastic contact ring is fixed in the socket body and butted with the cylindrical contact. The elastic contact ring is an open tube structure, the inner side of the open tube structure is evenly distributed with arc bumps, and the elastic contact ring is provided with a line seam along the tube axis. The diameter of the open tube of the elastic contact ring is 3~16 mm, the radius of the arc bump is 0.5~1 mm, and the height of the arc bump is 0.2~0.5 mm.

The structure has the advantages of simple processing, reliable performance, low contact resistance of multi contact elastic contact structure, and can meet the contact resistance requirements of lv215 customized High voltage connector supplier china.

In short, there are two trends in the structural design of customized High voltage connector supplier china. One is to change the original low-voltage surface contact into high-voltage double spiral curve structure, line spring structure, multi hole wear-resistant structure, leaf spring contact structure and elastic jack structure to increase the contact area, reduce the contact resistance and improve the current carrying capacity. The other is to reduce the contact resistance and improve the current carrying capacity by using multi contact contact ring, hollow connecting tube with array convex points and new cylindrical crown spring to directly realize point contact. The elastic high-voltage plug can directly form a linear contact with the socket, and does not need an intermediary such as a crown spring.
