[0001] This invention relates to the field of electrical connector technology, specifically to a high-current connector that is resistant to mis-mating and vibration. Background Technology

[0002] With the widespread application of electrical connectors in various industries, especially in harsh environments, the requirements for connector performance are becoming more stringent, as exemplified by high-current connectors required for the miniaturization of weaponry.

[0003] High-current connectors for some weapons and equipment require miniaturization. These connectors have a large number of internal contacts, are bulky, and require a lot of installation space. Most of them do not have anti-mismating or anti-reverse-mating functions. Especially in vibration and shock environments, they cannot provide good shock protection. The plugs and sockets of the connectors are prone to loosening, and their reliability and stability are not high. Therefore, a high-current connector with anti-mismating and vibration resistance is proposed to address the above problems. Summary of the Invention

[0004] The purpose of this invention is to provide a high-current connector that is anti-mis-mating and vibration-resistant, which is used to solve the problem of high-current connectors that meet the miniaturization requirements of some weapons and equipment. These high-current connectors have a large number of internal contacts, are large in size, have high requirements for installation space, and most of them do not have anti-mis-mating or anti-reverse-mating functions. Especially in vibration and shock environments, they cannot play a good role in shock protection. The plug and socket of the connector are easy to loosen, and the reliability and stability are not high.

[0005] To achieve the above objectives, the present invention provides the following technical solution:

[0006] A high-current connector with anti-misinsertion and vibration resistance includes a plug base and a socket base. The socket base is located at the bottom of the plug base. The plug base includes a plug plate, a plug shell, wires, pins, a base insert sleeve, a spring washer, and a screw. The plug shell is fixedly mounted on the bottom end of the plug plate. Wires are disposed inside the plug plate, and pins are fixedly mounted on the bottom ends of the wires. The base insert sleeve is fixedly mounted inside the plug plate and the plug shell.

The retaining plate 254 is fixedly provided on the outside of the inner sleeve plate 253. The spring wire 255 is obliquely clamped between the retaining plates 254 provided on the outside of the adjacent inner sleeve plates 253. Through the above arrangement, an assembled spring assembly 25 is formed.

[0034] Resin glue is filled between the inside of the plug plate 11 and the outside of the wire 13, thereby forming a potting and encapsulating effect on the plug base 1.

[0035] Resin glue is filled between the inside of the socket plate 21 and the outside of the socket wire 28, thereby forming a potting and sealing effect on the socket base 2.

[0036] The lower outer side of the front kit 251 is threadedly fitted to the inner side of the mounting sleeve 29, and the bottom end of the front kit 251 is in contact with the top end of the socket wire 28. Through the above arrangement, the installation of the wire spring assembly 25 and the socket wire 28 is limited.

[0037] The inner wall of the top of the front assembly 251 engages with the railing below the outer side of the inner sleeve plate 253, and the inner wall of the bottom of the rear assembly 252 engages with the railing above the outer side of the inner sleeve plate 253. Through the above arrangement, the combination and positioning of the wire spring assembly 25 are limited.

[0038] The spring wire 255 is slidably inserted into the outer side of the pin 14. Through the above arrangement, the spring wire 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.

[0039] Work process: This invention provides a high-current connector that is anti-misinsertion and vibration-resistant. The plug shell 12 of the main body of the device has rounded corners of varying sizes on the left and right sides to achieve anti-reverse insertion function. Under blind insertion conditions, 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 stable and reliable. It can achieve vibration resistance and impact resistance under harsh conditions and avoid accidental dislodgement.

[0040] The plug housing 12 inside the plug base 1 is divided into a left cavity and a right cavity. Each of the left and right cavities is equipped with a pin 14. The pin 14 is soldered to the wire 13. After soldering, it is assembled inside the plug plate 11 and the plug housing 12. Then, resin glue is poured between the inside of the plug plate 11 and the outside of the wire 13. A base insert cylinder 15 is fixed between the plug plate 11 and the plug housing 12. A spring washer 16 is placed on the top of the base insert cylinder 15.

[0041] The socket base 2 has a socket shell 23 inside, which is divided into a left cavity and a right cavity. The lower outer side of the front assembly 251 is threadedly fitted to the inner side of the mounting sleeve 29, so that the bottom end of the front assembly 251 is in close contact with the top end of the socket wire 28. The rear assembly 252 is placed on the top of the front assembly 251. Each of the left and right cavities contains a wire spring assembly 25. A retaining plate 254 is fixedly installed on the outer side of the inner sleeve plate 253. The wire spring wire 255 is obliquely clamped between the retaining plates 254 on the outer side of the adjacent inner sleeve plates 253. The inner sleeve plates 253 are manually squeezed inward to place the inner sleeve plates 253, retaining plates 254, and wire spring wire 255 vertically. Then, release the tension. Under the elastic reset action of the spring wire 255, the inner wall of the top of the front kit 251 engages with the railing set below the outer side of the inner sleeve plate 253, and the inner wall of the bottom of the rear kit 252 engages with the railing set above the outer side of the inner sleeve plate 253. After installation, place the spring assembly 25 and the socket wire 28 between the socket plate 21 and the socket housing 23. Then, fill the space between the inside of the socket plate 21 and the outside of the socket wire 28 with resin glue. Rotate the screw 17 to thread and lock the base insert cylinder 15 and the base insert sleeve 24. The bottom of the base insert sleeve 24 is equipped with a screw sleeve 26 for the installation of the printed circuit board.

[0042] After insertion, the wire 13, pin 14, spring assembly 25 and socket wire 28 are electrically connected. The main body of the plug base 1 and socket base 2 is made of engineering plastic, the pin 14 and spring assembly 25 are made of high elasticity copper alloy material, 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 double-core wire structure and a socket base 2 with a double-core bent plug printed circuit board structure. When the plug base 1 and the socket base 2 are plugged in, the wrap angle values ​​on the left and right sides of the bottom of the plug shell 12 are different, which can realize the functions of guiding, preventing mis-plugging and preventing reverse plugging.

[0044] The plug base 1 and socket base 2 can be threaded and locked by the accessories. The main structure of the accessories is simple and can effectively improve the anti-vibration, anti-impact and anti-loosening function of the connector device.

[0045] The connector device has fewer internal contacts, saving costs, simplifying the assembly process, and making it more conducive to mass production. The socket has a bent-type printed circuit board, and the plug has a wire. Even with limited installation space, it can be flexibly laid out and adjusted in practical applications. For longer lines, it can also buffer the turning angle of the line, reduce the pressure at the line connection, and make it less prone to breakage or damage. The plug base 1 and socket base 2 can be interlocked after being plugged in. After the pins of the bent-type printed circuit board are soldered to the printed circuit board, a threaded locking method can be used to enhance the connection reliability.

[0046] The individual contact inside the connector device can handle 80A of current, meeting the current market requirements for high current, small size, high stability, and high reliability. It can effectively solve the problem of miniaturized high-power power signal transmission in weaponry.

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