The clamping board 254 is fixedly arranged on the outer side of the inner sleeve board 253. The wire spring wires 255 are obliquely clamped between the clamping boards 254 arranged on the outer sides of adjacent inner sleeve boards 253. Through the above settings, the assembled and combined wire spring assembly 25 is formed.

[0034] Resin glue is filled and set between the inside of the plug board 11 and the outer side of the wire 13. Through the above settings, the glue filling and encapsulation effect on the plug base 1 is formed.

[0035] Resin glue is filled and set between the inside of the socket board 21 and the outer side of the socket wire 28. Through the above settings, the glue filling and encapsulation effect on the socket base 2 is formed.

[0036] The outer side below the front kit 251 is threadedly assembled with the inside of the installation sleeve 29. The bottom end of the front kit 251 is in close contact with the top end of the socket wire 28. Through the above settings, the installation limit of the wire spring assembly 25 and the socket wire 28 is achieved.

[0037] The inner wall at the top end of the front kit 251 is placed in a snap-fit manner with the bar provided below the outer side of the inner sleeve board 253. The inner wall at the bottom end of the rear kit 252 is placed in a snap-fit manner with the bar provided above the outer side of the inner sleeve board 253. Through the above settings, the combined limit of the wire spring assembly 25 is achieved.

[0038] The wire spring 255 is slidably inserted outside the pin 14. Through the above arrangement, the wire spring 255 made of high-elastic copper alloy material plays an elastic interlocking role after the plug base 1 and the socket base 2 are inserted into each other.

[0039] Working process: The present invention provides a large-current connector with anti-misinsertion and anti-vibration functions. The left and right sides of the bottom of the plug shell 12 of the device main body are provided with large and small rounded corners to achieve the anti-reverse insertion function. Under the blind insertion condition, the plug base 1 and the socket base 2 can be quickly inserted. The accessories of the connector device have a threaded locking function, and the connection is firm and reliable, and it can achieve the effects of anti-vibration and shock resistance under harsh conditions, avoiding accidental detachment.

[0040] The plug shell 12 arranged inside the plug base 1 is divided into a left cavity and a right cavity. Each of the left cavity and the right cavity is equipped with a pin 14. The pin 14 is welded to the wire 13. After welding, it is assembled inside the plug board 11 and the plug shell 12. Subsequently, resin glue is filled between the inside of the plug board 11 and the outside of the wire 13. A base insert cylinder 15 is fixedly arranged between the plug board 11 and the plug shell 12, and a spring washer 16 is placed on the top of the base insert cylinder 15.

[0041] The socket shell 23 arranged inside the socket base 2 is divided into a left cavity and a right cavity. The outer side below the front kit 251 is threadedly assembled with the inside of the mounting sleeve 29, so that the bottom end of the front kit 251 is in close contact with the top end of the socket wire 28. A rear kit 252 is placed on the top end of the front kit 251. Each of the left cavity and the right cavity is equipped with a wire spring assembly 25. A clamping plate 254 is fixedly arranged on the outer side of the inner sleeve plate 253. The wire spring 255 is obliquely clamped between the clamping plates 254 arranged on the outer side of the adjacent inner sleeve plates 253. Manually squeeze the inner sleeve plates 253 inward, place the inner sleeve plates 253, the clamping plates 254 and the wire spring 255 vertically, and then let go. Under the elastic reset action of the wire spring 255, the inner wall of the top end of the front kit 251 is clamped with the bar arranged below the outer side of the inner sleeve plate 253, and the inner wall of the bottom end of the rear kit 252 is clamped with the bar arranged above the outer side of the inner sleeve plate 253. After installation, the wire spring assembly 25 and the socket wire 28 are placed between the socket board 21 and the socket shell 23. Subsequently, resin glue is filled between the inside of the socket board 21 and the outside of the socket wire 28. The screw 17 is rotated to threadedly assemble and lock the base insert cylinder 15 and the base insert sleeve 24. A screw sleeve 26 is installed at the bottom of the base insert sleeve 24 for printed board installation.

[0042] After the insertion is completed, the wire 13, the pin 14, the wire spring assembly 25 and the socket wire 28 are electrically connected. The main bodies of the plug base 1 and the socket base 2 are made of engineering plastics. The pin 14 and the wire spring assembly 25 are made of high-elastic copper alloy materials, and the spring washer 16 is a standard part.

[0043] The connector device provided by the present invention has a plug base 1 with a two-core wire structure and a socket base 2 with a two-core bent plug printed circuit board structure. When the plug base 1 and the socket base 2 are plugged together, the corner wrapping values on the left and right sides at the bottom of the plug shell 12 are different, enabling functions such as guiding, preventing misplugging, and preventing reverse plugging.

[0044] The plug base 1 and the socket base 2 can be thread-locked by means of accessories. The accessory main structure is simple and can effectively improve the anti-vibration, shock resistance, and anti-loosening effects of the connector device.

[0045] The number of internal contacts of the connector device is small, saving costs and simplifying the assembly process, which is more conducive to mass production. The socket has a bent plug printed circuit board and the plug has a wire. Even in a limited installation space, it can be flexibly arranged and adjusted in practical applications. For a long line, it can also buffer the turning angle of the line, reduce the pressure at the line connection, making it not easily break or be damaged. After the plug base 1 and the socket base 2 are plugged together, they can be interlocked. After the pins at the bent plug printed circuit board end are welded to the printed circuit board, a thread-locking method can also be used to enhance the connection reliability.

[0046] A single contact inside the connector device can conduct a current of 80A, meeting the requirements of large current, small volume, high stability, and high reliability currently needed in the market, and effectively solving the problem of power signal transmission for miniaturized high-power weapon equipment.

[0047] Although the embodiments of the present invention have been shown and described, for those of ordinary skill in the art, it can be understood that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principles and spirit of the present invention. The scope of the present invention is defined by the appended claims and their equivalents.
