Among them, an annular groove is provided in the connection head 2. The clamping ring 41 is rotatably and slidably arranged in the annular groove. A plurality of clamping plates 42 are fixedly arranged in a circumferential manner at one end of the clamping ring 41, and a plurality of T-shaped rods 43 are fixedly arranged in a circumferential manner at the other end. The T-shaped rod 43 protrudes from the connection head 2, and a sliding groove for the T-shaped rod 43 to slide is provided on the connection head 2. A connection groove 11 is provided on the connection seat 1. A plurality of fixing blocks 12 are fixedly arranged in a circumferential manner in the connection groove 11. Two clamping blocks 13 with an inclined surface are fixedly arranged on the fixing block 12, and a clamping groove is provided between the clamping block 13 and the fixing block 12. The T-shaped rod 43 can slide along the inclined surface of the clamping block 13 and be clamped into the clamping groove. An annular limiting groove is provided on the connection seat 1. A limiting ring 14 is slidably arranged in a limiting manner in the limiting groove. A plurality of first springs 141 are fixedly arranged between the limiting ring 14 and the connection seat 1. A plurality of first pushing blocks 142 are fixedly arranged in a circumferential manner on the limiting ring 14. The first pushing blocks 142 are located between two adjacent fixing blocks 12 and slide along between the two fixing blocks 12. A plurality of second pushing blocks 21 are fixedly arranged in a circumferential manner on the connection head 2. The second pushing blocks 21 can push the first pushing blocks 142 to slide. A plurality of deflection grooves 22 are provided in a circumferential manner on the connection head 2. A strip-shaped plate 23 is slidably arranged in the deflection groove 22. A plurality of second springs 24 are arranged between the strip-shaped plate 23 and the connection head 2. The clamping plate 42 is slidably and rotatably arranged in the deflection groove 22, and the clamping plate 42 is slidably connected with the strip-shaped plate 23. The pushing ring mechanism 5 includes an annular plate 51, a push rod 52 and a pushing ring 53. Among them, an outer sleeve 25 is fixedly arranged on the connection head 2. A sealing ring 26 is arranged at one end of the outer sleeve 25 close to the connection seat 1. The sealing ring 26 has an inclined surface. The annular plate 51 is slidably arranged in the outer sleeve 25. A plurality of push rods 52 are fixedly arranged in a circumferential manner on the annular plate 51. The output end of the push rod 52 is fixedly provided with a pushing ring 53. The pushing ring 53 can slide along the inclined surface of the sealing ring 26. A plurality of annular grooves 511 are provided at the bottom of the annular plate 51. A plurality of ejector rods 421 are fixedly arranged in a circumferential manner on the clamping ring 41. The ejector rods 421 are clamped into the annular grooves 511 and slide along the annular grooves 511. A rectangular groove for the ejector rods 421 to slide and rotate is provided on the connection head 2.

[0016] Specifically, in a state where the terminal 2 is connected to the connecting seat 1, the ejector rod 421 abuts against one end of the annular groove 511, and during the process of the T-shaped rod 43 driving the snap ring 41 to rotate, the ejector rod 421 will slide towards the other end of the annular groove 511, that is, when the T-shaped rod 43 rotates, the torsion ring 6 will not rotate, and when the torsion ring 6 rotates, since the ejector rod 421 abuts against one end of the annular groove 511, the torsion ring 6 can drive the snap ring 41 to rotate.

[0017] During implementation, align the wiring head 2 with the connecting seat 1, and then push the wiring head 2 to slide and clamp it on the connecting seat 1. During this process, the push block 21 and the T-bar 43 will be clamped in the connecting groove 11, and the push block 21 will push the push block 1 142 to slide, and make the limit ring 14 compress the spring 1 141. At the same time, the T-bar 43 will slide along the inclined surface of the clamping block 13 under the action of the thrust, thereby making the clamping ring 41 rotate. The rotation of the clamping ring 41 further drives the clamping plate 42 to rotate. The rotation of the clamping plate 42 further pushes the strip plate 23 to rotate along the deflection groove 22 and compress the spring 2 24. Then, when the T-bar 43 slides to disengage from the clamping block 13, the The clamping block 13 no longer restricts the T-bar 43, and the clamping plate 42 will rotate under the thrust of the spring 24, and drive the clamping ring 41 and the T-bar 43 to rotate, so that the T-bar 43 is stuck in the clamping groove, thereby making the terminal head 2 and the connecting seat 1 clamped together, and then the terminal head 2 is released. At this time, the pushing block 21 no longer has thrust, and the limiting ring 14 will slide under the thrust of the spring 141, and push the pushing block 142 to slide, and further push the pushing block 21 and the terminal head 2 as a whole to slide toward the end away from the connecting seat 1. In this process, since the T-bar 43 is stuck in the clamping groove, the T-bar 43, that is, the clamping rod mechanism 4, will not slide. The annular plate 51 will not slide under the action of the push rod 421 and the annular groove 511. At this time, due to the sliding of the terminal head 2, the outer sleeve 25 will slide together and drive the sealing ring 26 to slide toward the end away from the connecting seat 1. Since the annular plate 51, that is, the entire push ring mechanism 5, will not slide, the push ring 53 will slide along the inclined surface of the sealing ring 26 and squeeze the sealing ring 26 during the sliding process, so that the sealing ring 26 is tightly attached to the connecting seat 1, thereby realizing the sealing of the connecting seat 1 and the terminal head 2, preventing the terminal head 2 from short-circuiting due to water ingress, and the separation of the terminal head 2 and the connecting seat 1 must make the T-bar 43 disengage from the slot, and the T-bar 43 must be rotated to disengage from the slot. Therefore, when the vehicle is bumpy during driving, the connection between the terminal head 2 and the connecting seat 1 will not loosen, and during the bumping process, the connecting wire 3 will pull the terminal head 2, so that the terminal head 2 has a force to separate from the connecting seat 1, and the terminal head 2 will be displaced on the connecting seat 1. During this process, since the push ring mechanism 5 always remains stationary, the push ring 53 will slide along the inclined surface of the sealing ring 26 until the push ring 53 completely presses against the end of the sealing ring 26, and as the push ring 53 slides along the inclined surface of the sealing ring 26, the extrusion force on the sealing ring 26 will become greater and greater, so that the sealing ring 26 will be closer to the connecting seat 1, and the more the terminal head 2 and the connecting seat 1 are pulled, the tighter the connection will be.Furthermore, it can avoid the disconnection between the terminal 2 and the connector base 1. When it is necessary to loosen the connection between the connector base 1 and the terminal 2, first slide the terminal 2, so that the push ring 53 disengages from the sealing ring 26, that is, the sealing ring 26 no longer tightly adheres to the connector base 1. Subsequently, rotate the torsion ring 6, so that the convex block 61 rotates and drives the annular plate 51 to rotate. The rotation of the annular plate 51 further drives the ejector rod 421 to rotate and drives the snap ring 41 to rotate, thereby enabling the T-shaped rod 43 to disengage from the card slot. Then, the terminal 2 can be pulled out from the connector base 1. At the same time, loosen the torsion ring 6 to reset the snap ring 41 and the annular plate 51, thereby making the connection and disassembly of the terminal 2 and the connector base 1 more convenient and the connection more stable, with better waterproof performance.

[0018] In this embodiment, a plurality of convex blocks 61 are fixedly arranged on the torsion ring 6 in a circumferential manner; A plurality of rectangular grooves 512 are formed in the top of the annular plate 51 in a circumferential manner, and the convex blocks 61 are slidably arranged in the grooves 512.

[0019] Specifically, the arrangement of the grooves 512 enables the convex blocks 61 to slide along the grooves 512 simultaneously when the terminal 2 drives the torsion ring 6 to slide, so that the rotation of the torsion ring 6 to drive the annular plate 51 is not affected by the sliding of the torsion ring 6.

[0020] In this embodiment, a plurality of insertion holes 15 are formed in the connector base 1; A plurality of insertion rods 27 are fixedly arranged on the terminal 2, and the insertion rods 27 can be slidably clamped into the insertion holes 15.

[0021] To sum up, when the present invention is implemented, through the setting of the clamping rod mechanism 4 and the push ring mechanism 5, the connection between the terminal 2 and the connector base 1 is more stable, and there is no risk of connection loosening or even water ingress due to vehicle bumps. At the same time, an outer sleeve 25 is arranged outside the terminal 2, and a sealing ring 26 is arranged on the outer sleeve 25. Through the cooperation of the sealing ring 26 with the push ring mechanism 5 and the clamping rod mechanism 4, after the terminal 2 and the connector base 1 are connected, the sealing ring 26 can tightly adhere to the connector base 1, thereby realizing the sealed connection between the terminal 2 and the connector base 1, improving its waterproof performance. And when the vehicle travels and generates bumps, causing a tensile force between the terminal 2 and the connector base 1, the sealing ring 26 will also be tightened more on the connector base 1 with the pulling, further making the connection between the connector base 1 and the terminal 2 more stable.

[0022] The above are only the preferred specific embodiments of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present invention, according to the technical solution and inventive concept of the present invention, making equivalent substitutions or changes should be covered within the protection scope of the present invention.
