[0002] With the continuous development of the times, the advancement of science and technology and the widespread application of various electronic devices, the requirements for the stability and reliability of electrical connectors are getting higher and higher. Stability plug-in electrical connectors came into being. It is a new type of connector designed to meet the needs of modern electronic equipment for high performance, high stability and high reliability. With the continuous advancement of science and technology and the continuous development of the times, stability plug-in electrical connectors will play an increasingly important role in the field of future electronic equipment.

[0003] According to the search of China Utility Model Publication No.: CN210350295U, a stable plug-in electrical connector is disclosed. The insulating body of the utility model includes a base, a tongue plate portion extending forward from the base, and a receiving groove recessed backward from the front end of the tongue plate portion. A circuit board is received in the receiving groove. The circuit board protrudes forward from the tongue plate portion to form a docking portion. A metal contact portion is provided on the docking portion. The tongue plate portion is used to plug with the docking connector. The metal contact portion is used to electrically connect with the conductive terminal of the docking connector. A limiting portion is provided on the outer side of the tongue plate portion. The limiting portion is used to limit the shell of the docking connector inward. Such a configuration can solve the damage to the circuit board and the docking connector terminals caused by oblique insertion and ensure the reliable contact between the stable plug-in electrical connector and the docking connector after mutual mating, thereby achieving an anti-swaying effect.

Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0026] See also Figure 1-4 The utility model provides an embodiment: a stable plug-in electrical connector, including a backplane 1 and a connecting mechanism 3, a special socket 2 is arranged on the left side of the backplane 1, a connecting mechanism 3 is arranged on the left side of the backplane 1, a terminal 301 is arranged inside the special socket 2, and a connecting wire 302 is arranged on the left side of the special socket 2.

[0027] Specifically, a first shell 303 is provided on the outside of the connecting line 302. The material of the first shell 303 is stainless steel. The right end of the first shell 303 is sleeved with a first waterproof cover 304. The material of the first waterproof cover 304 is fluororubber. The stainless steel material is strong and has strong corrosion resistance. It can protect the internal circuit structure and the service life of the device is long. The fluororubber material has strong plasticity and is resistant to high and low temperatures, which can prevent moisture from entering the inside of the device.

A plurality of hollow holes 307 are arranged on the surface of the contact core 306. The branch pipe 305 separates a plurality of lines through the branch pipe 305, thereby ensuring that each line has good contact, reducing signal interference or loss caused by poor contact, reducing crosstalk, and improving line stability, thereby reducing the risk of affecting the operation of the entire system due to problems in one line. The hollow design of the contact core 306 can increase the contact area, and the copper material has good conductivity.

[0029] Specifically, a second shell 308 is provided on the right side of the branch tube 305, and the second shell 308 is connected to the first shell 303 by a card slot. A waterproof coating 309 is provided on the surface of the second shell 308. The card slot connection structure is stable and easy to disassemble. The device can be quickly disassembled for easy maintenance and inspection. The design of the waterproof coating 309 increases the water resistance of the device.

[0030] Specifically, the right end of the second shell 308 is internally sleeved with one side of the inner sleeve 310, and the material of the inner sleeve 310 is polycarbonate.

The right end of the bundle tube 314 is provided with an opening shape. The outer side of the bundle tube 314 is sleeved with a third shell 315. The third shell 315 and the second shell 308 are threadedly connected. When the third shell 315 and the second shell 308 are threadedly connected, the pressure causes the opening part on the right side of the bundle tube 314 to close, thereby further clamping and fixing the line, highlighting the stability of the device.
