Description

Technical Field

[0001] The invention relates to a corrosion-resistant, low-gassing-rate and air-holding-proof electrical connector. Background Art

[0002] At present, with the continuous upgrading of the development scale and speed of the domestic chip and semiconductor industries, the domestic chip and semiconductor industries are constantly developing towards independence, high-end and complexity. A stable, clean and complex vacuum environment is crucial for semiconductor manufacturing. The existing connectors are bonded to the base by glue, and most glues will release gas in a vacuum environment and pollute the vacuum environment, causing the semiconductor material to be corroded and leak, resulting in a sharp decline in the stability of the semiconductor. For example, a converging electrical connector disclosed in CN115764389A has a mortise and tenon structure processed between the upper base and the lower base, and the mortise and tenon structure is connected by an adhesive. Although the mortise and tenon structure and the adhesive increase the pressure resistance of the connector in a vacuum environment, in order to avoid the adhesive from releasing gas in a vacuum environment, the adhesive has extremely high requirements, which will greatly increase the manufacturing cost of the connector. Summary of the invention

[0003] In order to solve the above technical problems, the present invention provides a corrosion-resistant, low-gassing and air-holding-proof electrical connector.

[0004] The present invention is achieved through the following technical solutions.

[0005] The present invention provides a corrosion-resistant, low-gassing, and air-holding-proof electrical connector, comprising:

[0006] The upper base includes a docking plate and a plug. The plug is fixed at the center of the docking plate. An upper screw hole is processed at both ends of the docking plate. The plug is processed with a plurality of upper base jacks that penetrate the docking plate and the plug.

[0007] The lower base has several lead holes in the center and two lower screw holes at both ends.

A connecting ear is fixedly connected to both sides of the tail cover and adjacent to the end of the wiring groove, and a countersunk hole is processed on the connecting ear;

[0009] The end faces of the docking plate and the lower base have the same shape, the end face of the docking plate facing away from the plug is connected to the lower base and is installed on the base mounting platform after the connection, and the two ends of the lower base are respectively in contact with two connecting ears; the number and position of the upper base jacks correspond to the lead connection holes; locking screws are installed in the countersunk holes, the lower screw holes, and the upper screw holes, and the threaded ends of the locking screws extend out of the upper screw holes.

[0010] The wire fixing groove and the wiring groove are also covered with a tail cover.

[0011] A tail cover limiting groove is also processed on both sides of the wire fixing groove. The bottom height of the tail cover limiting groove is higher than the wire fixing groove and a threaded hole is processed in the center. The shape of the tail cover is the same as the shape formed by connecting the tail cover limiting groove and the wiring groove and is fixed to the tail cover limiting groove by bolts.

[0012] Connecting nuts are also installed in the upper screw hole and the lower screw hole. The small diameter section at one end of the connecting nut extends into the upper screw hole, and the large diameter section at the other end of the connecting nut is placed in the lower screw hole, and its end is placed in the countersunk hole. A notch is also processed on the side of the lower screw hole, and the side of the large diameter section protrudes out of the notch. An internal thread is processed inside the connecting nut, and the locking screw is placed in the connecting nut.

[0013] The edges of the opposite surfaces of the docking plate and the lower base are also processed with positioning holes and positioning columns respectively. The positioning holes and positioning columns are respectively provided on the docking plate and the lower base and are not in a straight line. The positioning holes and positioning columns of the lower base are relatively positioned.

[0014] The connecting ears and the two sides of the lower base are also processed with through holes and base connecting internal threaded holes respectively and are connected by screws.

[0030] Furthermore, the end faces of the docking plate 11 and the lower base 3 have the same shape, and the end face of the docking plate 11 facing away from the plug 14 is connected to the lower base 3 and installed on the base mounting platform 58 after the connection, and the two ends of the lower base 3 are respectively in contact with the two connection ears 54; the number and position of the upper base jacks 15 correspond to the lead connection holes 35; the locking screws 2 are installed in the countersunk holes 55, the lower screw holes 34, and the upper screw holes 13, and the threaded ends of the locking screws 2 extend out of the upper screw holes 13. The docking plate 11 and the lower base 3 are installed on the connection ears in sequence, and the locking screws pass through the connection ears, the docking plate, and the two sides of the lower base in sequence, and the threaded ends thereof extend out to cooperate with the socket, and are used to fix the connector when the connector is assembled.

[0031] Furthermore, the wire fixing groove 51 and the wiring groove 57 are also covered with a tail cover 6. The tail cover 6 is used to close the connection between the lead wire and the base, and to press the lead wire into the wire fixing groove.
