1. Double helix and wire spring contact structure

In electric vehicles and hybrid electric vehicles, the contact structure solution of high current connector in motor control, motor drive and other parts is to adopt double spiral structure, with contact area of 65%, low plug-in force and high reliability, working voltage of 630 V, rated current of 455 a, relatively high overload capacity and Mechanical life of more than 500 times. Good price and quality High voltage connector Manufacturers china is one of the popular internal contact structures in the field of high-voltage connection of electric vehicles. The wire spring contact system adopted by Rosenberg can realize more than 40 contact points, with high current carrying capacity, space saving, low contact resistance and plug-in force.

2. Porous wear-resistant structure

There is a developed porous wear-resistant inner contact ring for good price and quality High voltage connector Manufacturers china of electric vehicle, which includes 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, concave in the middle, with an inner diameter of 5mm. Holes with a diameter of 1.5mm are staggered and evenly distributed on the pipe wall. There is a seam along the axis of the pipe, and the seam width is controlled within 0.5mm. 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 contact has the advantages of simple structure, reliable performance and wide application range, and can effectively popularize the application of high-voltage good price and quality High voltage connector Manufacturers china ; In this paper, the porous wear-resistant elastic inner contact ring realizes the mesh linear contact with the plug, and the contact resistance is low, which meets the contact resistance requirements of good price and quality High voltage connector Manufacturers china; The alloy coatings of AgCu, AGSB, AgPd and AuAg are used to replace the pure Ag or pure Au coating of the inner contact ring, which improves the wear resistance of the inner contact structure

3. Elastic socket contact

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 elastic strip into a shape including an arc-shaped contact part and a hook shaped fixed part. It is evenly arranged on 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.

4. Contact type elastic internal contact structure

Recently, there is a contact type elastic internal contact structure of electric vehicle good price and quality High voltage connector, 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, arc bumps are evenly distributed on the inner side of the open tube structure, and the elastic contact ring is provided with a line seam along the direction of 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, multi contact elastic contact structure and low contact resistance, which can meet the contact resistance requirements of good price and quality High voltage connector Manufacturers china.

Multiple array bumps are set on the inner wall of the laser hollowed connecting pipe, which can stably obtain the positive pressure of multiple contacts and ensure the reliability of contact.

5. Leaf spring contact structure

Leaf spring contact structure. The structure includes a main body part of C-type or ring design and several reeds formed on the main body. The reeds are provided with contact sheets facing the axis of the main body part. The reeds are provided with at least two rows along the axial direction of the main body, and the adjacent two rows are staggered in the axial direction, so as to obtain better elasticity and plug-in resistance.

6. New cylindrical crown spring

A new type of cylindrical crown spring is designed, which includes an upper end band and a lower end band arranged at both ends of the cylindrical crown spring, and a number of reeds arranged between the upper end band and the lower end band. Each reed has a contact part extending axially to the cylindrical crown spring. The technical scheme has more contact points, which can effectively reduce the contact resistance, and the inward protrusion of the spring is divided into multiple layers. In the process of pin insertion, it can contact the pin in layers, which can effectively reduce the insertion and removal force of the pin.

7. Elastic high voltage plug

Either of the above contact structures forms a secondary contact through an intermediary, rather than the direct contact between the plug and the socket, which increases the risk. The linear elastic contact piece of the elastic high-voltage plug at the contact end of the plug can directly form linear contact with the socket, ensuring good contact between the plug and the socket, and there is no need for intermediaries such as crown spring. Through the stainless steel annular opening, the linear shrapnel is embedded under the linear elastic contact sheet, which improves the fatigue resistance of the linear contact shrapnel and prolongs the service life. Silver nickel, or silver nickel nano graphite sheet, or silver nickel carbon nanotube composite coating is used to replace the conventional silver or gold coating, which improves the hardness and wear resistance of the coating and increases the plugging times of high-voltage terminals. Based on the high-voltage petal socket, the surface of the plug is made into tooth thread. Similarly, the linear contact between the plug and the socket is realized on the basis of no intermediate body to ensure the reliability of the contact of the good price and quality High voltage connector Manufacturers china.

8 conclusion

In short, there are two trends in the structural design of good price and quality High voltage connector Manufacturers china. One is to change the original low-voltage surface contact to the line contact of double spiral curve structure, line spring structure, porous wear-resistant structure, leaf spring contact structure and elastic jack structure under high pressure, so as to increase the contact area, reduce the contact resistance and improve the current carrying capacity. A new type of contact ring with multiple contact points and hollow out ring is used to reduce the direct contact resistance, while the other is the cylindrical contact ring with multiple contact points and hollow out ring. The elastic high-voltage plug can form a linear contact with the socket directly, and there is no need for intermediaries such as crown spring.
