[0026] To make the above-mentioned objects, features, and advantages of the present application more clearly understood, specific embodiments of the present application are described in detail below with reference to the accompanying drawings. The following description sets forth many specific details to facilitate a full understanding of the present application. However, the present application can be implemented in many other ways than those described herein, and those skilled in the art can make similar improvements without violating the scope of the present application. Therefore, the present application is not limited to the specific embodiments disclosed below.
[0027] In the fields of electronic equipment, electrical systems, and mechanical devices, connectors play a vital role as key components connecting different components.
[0028] Traditional connectors have certain limitations in terms of connection stability and reliability. In some environments with frequent vibrations or interference from external forces, ordinary connectors are prone to loosening or even disconnection, which may cause equipment failure, data loss or safety hazards. In addition, some connectors require additional fixing devices or manual inspections after connection to ensure the stability of the connection, which increases the complexity and cost of operation. This self-locking connector achieves a locking fit between the male plug and the female socket by matching the second locking block on the external rotating ring with the first locking block on the female socket. In addition, on the male plug, an elastic restoring force is provided by the internal rotating ring, spring and external rotating ring to ensure the stability of the locked state.
[0029] The specific structure of the self-locking connector is introduced as follows.
[0030] Figure 1 An exploded structural diagram of a self-locking connector provided in an embodiment of the present application; Figure 2 A diagram showing the combined structure of the second inner frame, inner rotating ring, and spring provided in an embodiment of the present application; Figure 3 A diagram showing the combined structure of an outer rotating ring and an inner rotating ring provided in an embodiment of the present application; Figure 4 This is a diagram of the internal structure of the male plug provided in an embodiment of the present application.
[0031] like Figures 1 to 4 As shown, an embodiment of the present application provides a self-locking connector, including: a female socket 100 and a male plug 200.
[0032] The female base 100 includes: a first inner frame 110, a locking groove 120 is provided on the outer circumference of the first inner frame 110, and a first locking block 130 is convexly provided on one inner groove surface of the locking groove 120 facing the other inner groove surface of the locking groove 120; the male plug 200 includes: a second inner frame 210, an outer rotating ring 220, an inner rotating ring 230 and a spring 240, the second inner frame 210 is detachably connected to the first inner frame 110, and the inner rotating ring 230, the spring 240 and the outer rotating ring 220 are all sleeved on On the second inner frame 210, the two ends of the spring 240 are respectively in contact with the second inner frame 210 and the inner rotating ring 230, and the outer rotating ring 220 is in contact with the inner rotating ring 230. A second locking block 221 that cooperates with the first locking block 130 is provided on the inner circumference of the outer rotating ring 220; the outer rotating ring 220 is configured to be able to drive the inner rotating ring 230 to rotate around the axis of the outer rotating ring 220, and make the inner rotating ring 230 compress the spring 240, so that the first locking block 130 and the second locking block 221 are separated.
[0033] Specifically, the first locking block 130 has a first inclined sliding surface, and the second locking block 221 has a second inclined sliding surface that slides with the first inclined sliding surface.
[0034] When the self-locking connector of the embodiment of the present application is in use, the second locking block 221 of the male plug 200 is aligned with the opening of the locking groove 120 of the female socket 100 and inserted; the second inclined sliding surface of the second locking block 221 slides with the first inclined sliding surface of the first locking block 130, causing the outer rotating ring 220 to rotate, thereby driving the inner rotating ring 230 to rotate synchronously, and at this time compressing the spring 240; when the second inclined sliding surface of the second locking block 221 disengages from the first inclined sliding surface of the first locking block 130, under the elastic force of the spring 240, the inner rotating ring 230 rotates and resets, thereby driving the outer rotating ring 220 to rotate and reset. At this time, along the axial direction of the male plug 200, the first locking block 130 and the second locking block 221 are abutted against each other, completing the self-locking connection between the male plug 200 and the female socket 100.
[0035] like Figures 1 to 4 As shown, in some embodiments, an annular protrusion 222 is provided on the inner circumference of the outer ring 220 at one end away from the inner ring 230. A limit plate 211 is provided on the outer circumference of the second inner frame 210, and an abutment plate abuts against the annular protrusion 222. This improves the connection stability between the outer ring 220 and the inner ring 230.
[0036] like Figures 1 to 4 As shown, in some embodiments, a first abutment groove 2111 is formed on the abutment plate, a second abutment groove 231 is formed on the inner rotating ring 230, and an abutment block 232 is provided on the inner rotating ring 230 near the second abutment groove 231. One end of the abutment block 232 extends to the open side of the second abutment groove 231. The extended end of the abutment block 232 and at least a portion of the bottom surface of the second abutment groove 231 together form an abutment space. One end of the spring 240 is inserted into the first abutment groove 2111 and abuts against the inner surface of the first abutment groove 2111. The other end of the spring 240 is located in the abutment space. This improves the connection stability between the spring 240, the inner rotating ring 230, and the abutment plate.
[0037] like Figures 1 to 4 As shown, in some embodiments, a limit stop 2112 is provided on the limit plate 211, and arcuate stops 233 are spaced apart on the inner ring 230. The surface of the arcuate stops 233 facing the limit plate 211 abuts the surface of the limit plate 211 facing the inner ring 230, and one side of the arcuate stops 233 abuts the arcuate stops 233. This restricts the freedom of the inner ring 230 along the axis of the male plug 200, allowing it to rotate only along the axis of the male plug 200, thereby compressing the spring 240.
[0038] For example, the number of the arc-shaped stoppers 233 is approximately two, and the two arc-shaped stoppers 233 are located outside the spring 240 , so as to prevent the position of the spring 240 from being shifted.
[0039] like Figures 1 to 4As shown, in some embodiments, the outer circumference of the inner ring 230 is provided with a mounting block 234, and the inner circumference of the outer ring 220 is provided with a mounting groove 223. The mounting groove 223 includes a first groove 2231 and a second groove 2232 that are connected. The first groove 2231 and the second groove 2232 are arranged perpendicularly, and the opening of the first groove 2231 is arranged away from the female base 100. The mounting block 234 enters from the first groove 2231 into the second groove 2232 and abuts against the second groove 2232. In this way, a stable connection between the outer ring 220 and the inner ring 230 is achieved.
