[0030] The application is further described below in combination with the drawings and specific embodiments: EMBODIMENT

[0031] As shown in the drawings, Figure 1 The waterproof quick-detaching interface of the application mainly comprises a ring electrode module, a waterproof quick-detaching shell module, a positioning mechanism and a quick-detaching button waterproof assembly.

[0032] The male end of the ring electrode module is composed of a conductive ring convex ring 3, and the female end is composed of an insulating ring convex ring 4. When the conductive ring convex ring 3 and the insulating ring convex ring 4 cooperate, the electrode gap is filled with insulating material, which plays a role of water isolation and short circuit prevention. The electrode is fixedly connected with a line tube disc 5 through a screw, the line tube is installed on a waterproof partition plate inside the waterproof shell through a flange plate 8, the flange plate and the partition plate inside the shell limit the axial movement of the electrode, and reliable connection is ensured.

[0033] As shown in the drawings, Figure 2 In the ring electrode module, the male end is connected with the line tube disc 5 through the flange connecting lug 13 by a bolt and a nut. The male end line tube disc is provided with two spring limiting columns 11 and a spring at the back, and when the interface is plugged and cooperated, the spring can make the male end of the ring electrode tightly cooperate with the female end.

[0034] As shown in the drawings, Figure 1 The waterproof quick-detaching shell comprises a plug-in A end 1 and a plug-in B end 2. The shell interface of the plug-in A end 1 is provided with a lower concave step 8, which forms a closed cavity when the shell of the plug-in B end 2 is closed. A rubber sealing ring 7 is arranged at the lower concave step to prevent water from entering.

[0035] As shown in the drawings, Figure 4 The quick-detaching button 6 is covered by a waterproof silica gel film. The silica gel film is durable and has excellent sealing performance, can effectively seal the possible water seepage gap, prevent water from seeping in, and at the same time, the silica gel material has a comfortable hand feeling, which improves the user experience.

[0036] AsFigure 1 As shown, the A-end 1 housing end is provided with a positioning groove 10, and the B-end 2 housing end is provided with a positioning protrusion 15 matched with the positioning groove, for realizing quick alignment. The quick release button will not pop up when not installed in place, and the internal circuit cannot be powered on, avoiding damage to the equipment due to misoperation.

[0037] As shown Figure 5 The annular electrode module male end is fixed in the A-end 1 through longitudinal limiting of the waterproof partition plate 17 inside the A-end 1 and longitudinal limiting of the flange plate 8, and can only move in axial small amplitude.

[0038] As shown Figure 3 The annular electrode adopts concentric circle structure design, allowing a certain degree of looseness when the electrodes are matched, without affecting power and signal transmission, and significantly improving the reliability of underwater operation. The waterproof material of the annular electrode female end can completely isolate moisture and prevent electrode damage caused by short circuit.

[0039] As shown Figure 4 On the basis of the traditional design, the quick release button is newly added with an embedded silica gel film, which is integrally formed with the button to wrap the entire button assembly, ensuring that there is no gap at the button position and avoiding moisture penetration. In addition, the silica gel material has flexibility and durability, without affecting the normal operation of the button.

[0040] A rubber sealing ring is added at the lower recessed step of the A-end of the housing, so that when the A-end and the B-end housings are plugged together, a multiple sealing structure can be formed, further improving the waterproof performance.
