[0035] Refer to Figures 1 to 4 , an embodiment of the present utility model provides a fast-connecting connector, including a plug assembly 100, a socket assembly 300, and a protection assembly 500; the plug assembly 100 includes a plug housing 200 and a connecting sleeve 110, the connecting sleeve 110 is rotatably connected to the plug housing 200, at least three connecting blocks 111 are provided on the inner wall of the connecting sleeve 110, and at least three connecting blocks 111 are arranged at intervals along the circumferential direction of the connecting sleeve 110. The socket assembly 300 is provided with a socket housing 400, one end of the socket housing 400 is provided with a connecting pipe 410, at least three guide grooves 411 are provided on the outer wall of the connecting pipe 410, the guide grooves 411 are spirally arranged, a clamping block 412 is provided in the guide grooves 411, and the connecting block 111 can move along the guide grooves 411. By rotating the connecting sleeve 110, at least three connecting blocks 111 correspondingly move along at least three guide grooves 411, so that the connecting pipe 410 is quickly connected to the connecting sleeve 110, realizing the quick connection of the plug housing 200 and the socket housing 400, and improving the installation efficiency of the connector. The clamping block 412 in the guide groove 411 is buckled on the connecting block 111, so that the connecting block 111 is fixed in the guide groove 411, preventing the connecting block 111 from sliding out of the guide groove 411, and preventing the connecting sleeve 110 from separating from the connection in a vibrating environment, thereby improving the connection strength between the plug assembly 100 and the socket assembly 300.

[0036] It can be understood that when the connecting block 111 moves along the guide groove 411, the contact between the connecting block 111 and the guide groove 411 is surface contact. Compared with the point contact in screw connection, the surface contact between the connecting block 111 and the guide groove 411 can improve the sealing performance between the connecting sleeve 110 and the connecting pipe 410, and thus enhance the sealing performance of the connector.

[0037] It can be understood that the socket housing 400, the plug housing 200, and the connecting sleeve 110 are made of non-metallic materials. Non-metallic materials are beneficial to reducing the weight of the connector. Compared with metallic materials, non-metallic materials have stronger plasticity, are easier to produce and manufacture, and can reduce production costs. At the same time, non-metallic materials have high environmental resistance, are not easily corroded and oxidized, and have good heat resistance. It can be understood that the materials of the socket housing 400, the plug housing 200, and the connecting sleeve 110 can be plastics, rubbers, etc., which can be selected according to actual production applications, and the present application does not limit this here.

[0038] It can be understood that the guide groove 411 is spirally arranged on the outer peripheral wall of the connecting pipe 410. In the axial direction of the connecting pipe 410, the central angle corresponding to the arc of the guide groove 411 is A, and the design satisfies: 270º≤A≤360º. When A is less than 270°, the spiral coverage range of the guide groove 411 is small, and when subjected to external force or vibration, the connecting block 111 is likely to disengage from the guide groove 411, making the connection between the connecting sleeve 110 and the connecting pipe 410 unstable and not conducive to the stability of the connection between the plug assembly 100 and the socket assembly 300. When A is greater than 360°, the processing difficulty of the guide groove 411 increases, and the connection difficulty between the connecting sleeve 110 and the connecting pipe 410 also increases, which is not conducive to the quick connection between the connecting pipe 410 and the connecting sleeve 110. Therefore, 270º≤A≤360º to ensure the stable connection between the connecting block 111 and the guide groove 411. At the same time, it ensures the quick connection between the connecting sleeve 110 and the connecting pipe 410 and reduces the processing difficulty of the guide groove 411.

[0039] Refer to Figure 6 In some embodiments of the present utility model, the guide groove 411 includes a moving section 4111 and a fixed section 4112. The clamping block 412 is located between the moving section 4111 and the fixed section 4112, and the width of the fixed section 4112 is greater than that of the moving section 4111. It can be understood that the connecting block 111 has elasticity so that the connecting block 111 can deform. The connecting block 111 enters the fixed section 4112 from the moving section 4111. There is an interference fit between the connecting block 111 and the moving section 4111, and the connecting block 111 is in a compressed state within the moving section 4111. Since the width of the fixed section 4112 is greater than that of the moving section 4111, the connecting section resumes deformation after the connecting block 111 enters the fixed section 4112, making the connection between the connecting block 111 and the fixed section 4112 more stable and avoiding the connecting block 111 disengaging from the fixed section 4112 in a vibrating environment, thereby making the connection between the connecting sleeve 110 and the connecting pipe 410 more stable. By having the clamping block 412 located between the moving section 4111 and the fixed section 4112, after the connecting block 111 enters the fixed section 4112, the connecting block 111 is buckled to the clamping block 412, avoiding the connector disengaging from the fixed block in a vibrating environment and ensuring the stability of the connection between the plug assembly 100 and the socket assembly 300.

[0040] Refer toFigure 2 and Figure 8 , in some embodiments of the present utility model, a first identifier 112 is provided on the outer wall of the connecting pipe 410, and a second identifier 201 is provided on the outer wall of the plug housing 200. When the connecting block 111 is located in the fixed section 4112, the first identifier 112 is aligned with the second identifier 201. By aligning the first identifier 112 with the second identifier 201, it is ensured that the connecting block 111 is within the fixed section 4112, ensuring the proper connection of the plug assembly 100 and the socket assembly 300. At the same time, during use, it is possible to determine whether the connection between the plug assembly 100 and the socket assembly 300 is loose based on the relative positions of the first identifier 112 and the second identifier 201, which helps improve the maintenance efficiency.

[0042] Refer to Figures 2 to 4 , in some embodiments of the present utility model, the protection assembly 500 includes a wire sealing body 510 and a rear cover 520.

A limiting block 511 is provided on the outer wall of the wire sealing body 510, and a limiting groove 521 is provided on the side wall of the rear cover 520. The limiting block 511 is located within the limiting groove 521, preventing the wire sealing body 510 from rotating relative to the rear cover 520, and thus preventing the wire sealing body 510 from driving the cable to rotate and damage the cable.

[0043] Refer to Figure 2 , Figure 4 and Figure 8, in some embodiments of the present utility model, a protection component 500 is connected to the side of the plug housing 200 facing away from the connecting pipe 410.

By having the mounting blocks 522 located inside the first mounting holes 211, the connection between the rear cover 520 and the plug housing 200 is made more stable. By connecting the wire sealing body 510 and the rear cover 520 to the first mounting pipe 210, compared with setting a sealing member at the end of the plug housing 200, the rear cover 520 can prevent the cable at the end of the plug housing 200 from being excessively bent and causing waterproof failure, further protecting the cable at the end of the plug housing 200 and improving the waterproof performance of the plug assembly 100. By the abutting ring 523 of the rear cover 520 abutting against the end of the first mounting pipe 210, the sealing performance of the plug housing 200 is improved, and the waterproof performance of the plug assembly 100 is further improved.

By connecting the wire sealing body 510 and the rear cover 520 to the second mounting pipe 420, compared with setting a sealing member at the end of the socket housing 400, the rear cover 520 can prevent the cable at the end of the socket housing 400 from being excessively bent and causing waterproof failure, further protecting the cable connected to the socket housing 400 and improving the waterproof performance of the socket assembly 300. By the abutting ring 523 of the rear cover 520 abutting against the end of the second mounting pipe 420, the sealing performance of the socket housing 400 is improved, and the waterproof performance of the socket assembly 300 is further improved.
