[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] Referring to Figures 1-6, this utility model discloses a waterproof device for an endoscope plug socket, comprising:

[0024] The plug socket 18 has a through hole inside, and a socket needle 20 is installed inside the through hole. One end of the socket needle 20 is connected to the cable of the endoscope, and the end of the socket needle 20 near the cable is connected to the inner wall of the plug socket 18. A limiting groove 19 is provided on the side wall of the plug socket 18. The limiting groove 19 is concentric with the through hole, and the diameter of the limiting groove 19 is larger than the diameter of the through hole. A foolproof groove 21 is provided on the inner wall of the plug socket 18. The foolproof groove 21 is arranged along the axial direction of the through hole and communicates with the limiting groove 19. The height of the foolproof groove 21 is not greater than the height of the limiting groove 19.

[0025] Waterproof cap 1 is located at the end of plug socket 18 away from the cable. Waterproof cap 1 includes housing 8. The diameter of the outer wall of housing 8 is adapted to the diameter of the through hole. One end of housing 8 is provided with an opening that allows the socket pin 20 to enter the interior of housing 8. The outer wall of housing 8 is provided with a slider adapted to the anti-fooling groove 21.

[0026] During the process of connecting the plug socket 18 and the waterproof cap 1, the slider is placed in the anti-fooling groove 21 and slid until the slider reaches the limiting groove 19. At this time, the socket pin core 20 enters the housing 8. The housing 8 is rotated, and the slider moves from the anti-fooling groove 21 into the limiting groove 19. At this time, the slider can only rotate in the limiting groove 19. Due to the restriction of the limiting groove 19, the slider cannot slide along the axial direction of the through hole, thus limiting the housing 8 and preventing the waterproof cap 1 from falling off the plug socket 18, ensuring the protective effect of the plug socket 18.

[0027] In some embodiments, a positioning groove 23 is provided at the end of the plug socket 18 away from the cable. The diameter of the inner wall of the positioning groove 23 is larger than the diameter of the through hole. The positioning groove 23 communicates with the through hole. A positioning boss 4 is provided on the housing 8. When the pin core of the plug socket 18 contacts the end of the housing 8 away from the opening, the positioning boss 4 is located in the positioning groove 23 and contacts the inner wall of the positioning groove 23.

[0028] The positioning groove 23 and the positioning boss 4 cooperate to control the mating depth of the housing 8 and the plug socket 18. When the end of the positioning boss 4 near the plug socket 18 contacts the end of the positioning groove 23 near the through hole, the socket pin core 20 contacts the end of the housing 8 away from the opening.

[0029] In some embodiments, multiple positioning bosses 4 are provided, and a sealing groove is formed between two adjacent positioning bosses 4, and a sealing ring is provided in the sealing groove.

[0030] The sealing ring ensures the airtight connection between the housing 8 and the plug socket 18. After the waterproof cap 1 is connected to the plug socket 18, the cooperation between the side wall of the waterproof cap 1, the sealing ring and the side wall of the plug socket 18 prevents liquid from entering the plug socket 18.

[0031] In some embodiments, three positioning bosses 4 are provided, and a first sealing groove 3 and a second sealing groove 10 are formed between two adjacent positioning bosses 4 respectively. A first sealing ring 6 is provided in the first sealing groove 3, and a second sealing ring 7 is provided in the second sealing groove 10.

[0032] In some embodiments, the slider is a pin 9, and the housing 8 has a pin hole 5 at one end near the cable. One end of the pin 9 is disposed in the pin hole 5, and the other end of the pin 9 contacts the anti-fooling groove 21.

[0033] In some embodiments, an anti-slip groove 2 is provided on the outer wall of the housing 8 at the end away from the plug socket 18.

[0034] The anti-slip groove 2 ensures that the operator can smoothly install and remove the waterproof cap 1 while wearing rubber gloves.

[0035] In some embodiments, a first lifting ring 13 is provided at the end of the housing 8 away from the plug socket 18.

[0036] In some embodiments, the end of the housing 8 away from the plug socket 18 is provided with a mounting hole 12, the first lifting ring 13 passes through the mounting hole 12, a connecting chain 14 is connected to the first lifting ring 13, the end of the connecting chain 14 away from the first lifting ring 13 is connected to a second lifting ring 15, and the second lifting ring 15 is connected to the nameplate 17 through a connecting hole 16.

[0037] The nameplate 17 is printed with instructions on how to use the waterproof cap 1, precautions for operation, and warning information to guide and remind the operator to avoid incorrect operation that could lead to liquid ingress and corrosion of the plug socket 18, affecting the electrical connection.

[0038] In some embodiments, a handle is provided on the outer side of the plug socket 18, a first mark point 11 is provided on the housing, and a second mark point 22 is provided on the handle. When the slider is in the anti-fooling groove 21, the first mark point 11 and the second mark point 22 are located on the same straight line.

[0039] During the process of connecting the waterproof cap 1 and the plug socket 18, the first mark point 11 and the second mark point 22 are on the same straight line. After rotating the waterproof cap 1 and completing the connection between the waterproof cap 1 and the plug socket 18, the first mark point 11 and the second mark point 22 are in different positions. By checking the positional relationship between the first mark point 11 and the second mark point 22, it can be determined whether the waterproof cap 1 and the plug socket 18 have been successfully connected, ensuring a stable connection between the waterproof cap 1 and the plug socket 18, thereby ensuring the protective effect of the waterproof cap 1 on the plug socket 18.
