[0002] An electronic connector is also often referred to as a circuit connector or an electrical connector, which bridges two conductors on a loop so that current or signals can flow from one conductor to another. An electronic connector is an electrical system that provides a separable interface for connecting two sub-electrical systems.

[0003] The existing connectors have the following deficiencies when in use:

[0004] 1. When inserting the connector, it is impossible to well control the pressing force, which may cause the terminal to be inserted too deep during use and unable to play a certain limiting and buffering role, resulting in terminal damage.

[0005] 2. Currently, general electronic connectors are structured with multiple terminals embedded and molded in an insulating body, and the solder feet of the terminals directly extend out of the base. Due to the small amount of glue position at the rear plug buckle of the connector in the prior art, the position degree of the terminal solder feet cannot be guaranteed.

[0006] 3. The threaded thickness of the installation screw holes of the existing electronic connectors is 2.8 mm, and the installation strength (torque test) is relatively low.

[0007] In summary, this application proposes a connector that can limit the insertion depth of the terminal, ensure the position degree of the terminal solder feet, and has a relatively high installation strength. Content of the Utility Model

Specifically, when the connector is inserted into work, the long terminal 5 and the short terminal 4 are inserted into the corresponding positions. When inserting, when the limit disk 10 contacts the connector, the insertion depth of the long terminal 5 and the short terminal 4 is limited by the limit disk 10, and a certain buffering effect is achieved under the action of the spring 9, avoiding damage to the long terminal 5 and the short terminal 4 caused by excessive insertion when the connector is inserted into work, and the position of the adjusting rod 13 can be adjusted to adjust the elastic force of the spring 9. At this time, the limit bolt 15 is unscrewed, the adjusting rod 13 is moved, and then the limit bolt 15 is screwed into the corresponding first threaded hole 14 to limit the adjusting rod 13, so that when the limit disk 10 performs the limiting function, the elastic force of the spring 9 can be adjusted, thereby adjusting the buffering ability of the spring 9.

[0027] In this embodiment, a rear plug 3 is provided on the outer surface at the rear side of the main body 2, a buckle 6 is provided on the outer surface of the rear plug 3, and a plurality of glue positions are provided at the position of the buckle 6 on the rear plug 3. Specifically, by adding glue at the buckle 6 of the rear plug 3, the positional accuracy of the terminal solder feet is ensured to be 0.30 mm.

[0028] In this embodiment, fixing members are provided at both ends of the main body 2, and a second threaded hole 17 is formed on the outer surface of the fixing bracket. The threaded depth of the second threaded hole 17 is 3.8 mm. Specifically, in the prior art, the threaded depth of the second threaded hole 17 used for installation is 2.8 mm, and in this application, it is increased to 3.8 mm to increase the threaded depth and enhance the installation strength.

[0029] In this embodiment, a plurality of short terminals 4 and long terminals 5 are provided inside the main body 2, and the short terminals 4 and the long terminals 5 are located in parallel planes. Specifically, during assembly, the short terminals 4 are first assembled onto the main body 2, and then the long terminals 5 are assembled onto the main body 2.

[0030] In this embodiment, a sliding groove 16 is formed on the outer surface of the main body 2 between two groups of first threaded holes 14, and the sliding rod 11 is slidably connected to the inside of the sliding groove 16. Specifically, when adjusting the position of the adjusting rod 13, the adjusting rod 13 drives the sliding rod 11 to slide inside the sliding groove 16, and the sliding groove 16 provides a channel for the sliding of the sliding rod 11.

[0031] In this embodiment, the limiting disc 10 is located outside the receiving groove, and the diameter of the limiting disc 10 is larger than the diameter of the receiving groove. Specifically, with the above technical solution, when the connector is connected, the limiting disc 10 can be located between the connector and the connecting member, preventing the limiting disc 10 from being received inside the receiving groove.

[0032] Working principle: When the utility model is in use, the device is assembled. During assembly, first assemble the short terminal 4 onto the main body 2, then assemble the long terminal 5 onto the main body 2, and finally assemble the rear plug 3 onto the main body 2. Then assemble the main body 2 onto the outer shell 1, and rivet the cylindrical pin 7 to the outer shell 1. When the connector is inserted, insert the long terminal 5 and the short terminal 4 into the corresponding positions. When inserting, when the limit disk 10 contacts the connecting part, the depth of insertion of the long terminal 5 and the short terminal 4 is limited by the limit disk 10, and a certain buffering effect is achieved under the action of the spring 9, avoiding damage to the long terminal 5 and the short terminal 4 caused by excessive insertion depth during the connector insertion operation. The position of the adjusting rod 13 can be adjusted to adjust the elastic force of the spring 9. At this time, unscrew the limit bolt 15, move the adjusting rod 13, and then screw the limit bolt 15 into the corresponding first threaded hole 14 to limit the adjusting rod 13. Thus, when the limit disk 10 performs the limiting function, the elastic force of the spring 9 can be adjusted, thereby adjusting the buffering ability of the spring 9. When installing this connector, screw the installation bolt into the second threaded hole 17. The thickness of the second threaded hole 17 is increased, strengthening the installation strength, and applying glue at the buckle 6 of the rear plug 3 to ensure that the position degree of the terminal welding foot is 0.30 mm.
