How is china High voltage connector components designed

(Summary description)The design of china High voltage connector components without air gap has special requirements for the connector insertion interface and wire end connector. When the voltage is high, the dielectric withstand voltage and creepage distance have new significance. With the trend of miniaturization of china High voltage connector components structure, the size of china High voltage connector components is getting smaller and smaller, and the distance between the contactor and the shell is very small. Therefore, special structures must be used to increase the creepage distance. The mounting plate of china High voltage connector components shall be designed as an axially convex "conical platform" and corresponding "conical hole", and at least one mounting plate shall be made of silicone rubber. This structure increases the creepage distance between the contactors. Due to the existence of the conical surface, the entire mating surface can apply the same pressure. Under a certain interface pressure, the soft mounting plate can produce a certain compression, and a sealing structure is added on the soft mounting plate, so as to more effectively eliminate the gap connection between the electrodes and achieve the purpose of eliminating the air gap on the interface. The compression amount of the soft mounting plate is controlled by the combination of "conical platform, hole" and spring.

The design of china High voltage connector components without air gap has special requirements for the connector insertion interface and wire end connector. When the voltage is high, the dielectric withstand voltage and creepage distance have new significance. With the trend of miniaturization of china High voltage connector components structure, the size of china High voltage connector components is getting smaller and smaller, and the distance between the contactor and the shell is very small. Therefore, special structures must be used to increase the creepage distance. The mounting plate of china High voltage connector components shall be designed as an axially convex "conical platform" and corresponding "conical hole", and at least one mounting plate shall be made of silicone rubber. This structure increases the creepage distance between the contactors. Due to the existence of the conical surface, the entire mating surface can apply the same pressure. Under a certain interface pressure, the soft mounting plate can produce a certain compression, and a sealing structure is added on the soft mounting plate, so as to more effectively eliminate the gap connection between the electrodes and achieve the purpose of eliminating the air gap on the interface. The compression amount of the soft mounting plate is controlled by the combination of "conical platform, hole" and spring.

The overall structural design of china High voltage connector components is as follows:

The fixed end electrical connector and the free end electrical connector are composed of a contactor, an insulating mounting plate, a shell and tail accessories. The free end connector is installed with a pin contactor, and the mounting plate is made of silicon rubber with good dielectric strength and elasticity; The fixed end electrical connector is equipped with a jack contact assembly, and the mounting plate is made of hard insulating material. In order to prevent misinsertion, the housing of the free end electrical connector and the housing of the fixed end electrical connector are designed with a five key slot structure; For the purpose of quick separation, the free end connector housing is connected with the sleeve. The inner hole wall of the connecting sleeve is designed with three bayonet spiral grooves of equal pitch spiral structure. The bottom of the groove is known to have a bayonet hole, and the engaging table of the connector can be observed; Correspondingly, the surface of the fixed connector housing is designed with three clips, which can be rotated to the bottom of the spiral groove. After the free end electrical connector is rotated in place, the connector can be locked. On the free end connector, rotate the connecting sleeve clockwise to complete the connection and counterclockwise to complete the separation. When china High voltage connector components is fully engaged and the connecting sleeve is in the locking position, the corresponding hole of the connecting sleeve can be seen.

The four core china High voltage connector components shall be designed to maintain a constant interface pressure during use. The way to accomplish this task is to use a locking mechanism. In order to prevent harmful gas, moisture, salt mist and water from entering the connector and improve the service life and reliability of the connector, the free end electrical connector is connected with the fixed end electrical connector with the help of the structural design.

China High voltage connector components with plug-in interface design

In order to meet the high-voltage performance requirements of the connector, the mounting plate must be designed with different structures of the general connector. On the insertion interface of the connector, the free end adopts silicon rubber soft mounting plate, which is designed as a concave "taper hole" structure for fixing the pin contactor; The fixed end adopts DAP hard mounting plate and is designed as a convex "cone" structure to fix the jack contactor.

Wire seal of china High voltage connector components

The wire seal includes the wire seal of the free end connector and the fixed end connector. For fluoroplastic wire, in order to make the wire bond firmly, sand blasting must be carried out to make its surface rough, and then strong oxidizing treatment agent is used to corrode the wire. The corrosion process causes the molecules on the wire surface to react to form a free radical carbon containing film. The carbon containing film reacts with the sealing adhesive to form a real chemical adhesive.

When the wire is welded with the contact, the area of the welding spot is small and flush with the surface of the contact. On the one hand, it can avoid the damage of the surface coating of the contact due to the large area of the welding spot. On the other hand, it can also avoid the discharge of the tip of the welding spot protrusion or concave bow. It is easy to cause the gas adsorption to form an "air pump" during the molding. In the free end connector, the treated wire is welded with the contactor, coated with silicone rubber adhesive, and sent to the silicone rubber soft mounting plate with tools, Then press the hard mounting plate with the connecting nut to support the soft mounting plate.

Install the board and wires of china High voltage connector components.

Two problems should be solved for wire welding in fixed china High voltage connector components, one is the creepage distance on the bonding interface, and the other is the wire sealing.
