[0026] The connector body 301 is used to install the electrical connection plug, the tube body 302 is used to sleeve the cable to prevent the cable and the sealing door 401 from contacting and being damaged, the plate body 303 is used to install the one-way teeth 304, the one-way teeth 304 and the one-way tooth grooves 305 form a one-way snap connection, so that the one-way teeth 304 can move directly backwards, and when the plate body 303 is pulled forward, the one-way teeth 304 and the one-way tooth grooves 305 form a snap connection, and the connector body 301 cannot be pulled out, so that the connection between the electrical connection jack and the electrical connection plug is more stable.

[0027] The elastic component includes a sliding column 307, one end of which is fixedly connected to the plate body 303, and the other end of the sliding column 307 is slidably connected to the joint body 301. A coil spring 306 is provided on the outer side of the sliding column 307, and the two ends of the coil spring 306 are respectively fixedly connected to the plate body 303 and the joint body 301.

[0028] The slide column 307 is used to sleeve the coil spring 306 and keep the distance between the plate body 303 and the joint sub-body 301 adjustable. The coil spring 306 pushes the plate body 303 outward to keep the one-way teeth 304 and the one-way tooth grooves 305 engaged.

[0029] The guide assembly includes a slide trough body 308 , which is fixedly connected to the upper and lower surfaces of the joint sub-body 301 . The slide trough body 308 is slidably connected to a slide bar 309 , and the slide bar 309 is fixedly connected to the joint mother body 100 .

[0030] The sliding connection between the sliding post 307 and the sliding groove body 308 is used to guide the position of the connector sub-body 301 inside the square hole 200 to ensure the connection between the electrical connection socket and the electrical connection plug.

[0031] A rounded corner 1 is provided on the front side of the slide bar 309 , and a rounded corner 2 is provided on the rear side of the slide groove body 308 for facilitating the slide bar 309 to slide in.

[0032] The rounded corners 1 and 2 facilitate the quick guidance of the slide groove body 308 and the slide post 307 together when the joint sub-body 301 is inserted.

[0033] The sealing mechanism includes two sealing doors 401 that open inwards. The sealing doors 401 are inwardly opened. A notch 403 that cooperates with the tube body 302 is provided in the middle of the side where the two sealing doors 401 are close to each other. A spring sheet 402 is provided on the inner side of the sealing door 401 to keep the sealing door 401 closed.

[0034] The spring sheet 402 uses its own elasticity to keep the sealing door 401 automatically closed. The sealing door 401 is used to keep the inside of the square hole 200 clean and moisture-proof. The notch 403 is used to keep the sealing door 401 closed when the tube body 302 is extended.

[0035] The removal mechanism includes a slider 501 which is slidably connected to the tube body 302 . The four corners of the rear side of the slider 501 are fixedly connected to the squeezing plates 502 . The front end of the plate body 303 is provided with an inclined plate 503 used in conjunction with the squeezing plates 502 .

[0036] The slider 501 is used to install the extrusion plate 502. The extrusion plate 502 slides backward to knock open the sealing door 401 and then enters the square hole 200. The extrusion plate 502 squeezes the inclined plate 503, so that the inclined plate 503 drives the plate body 303 to approach the joint body 301, so that the one-way tooth 304 leaves the one-way tooth groove 305. The clamping is released.

[0037] Working principle:

[0038] The connector sub-body 301 is dragged to knock open the sealing door 401, and the connector sub-body 301 enters the square hole 200. The slide groove body 308 and the slide bar 309 begin to slide and connect, guiding the electrical connection plug on the connector sub-body 301 to be plugged into the electrical connection jack inside the square hole 200. At the same time, the one-way teeth 304 and the one-way tooth grooves 305 on the plate body 303 form a one-way clamping connection, so that the plate body 303 and the connector sub-body 301 cannot move forward, preventing the electrical connection jack and the electrical connection plug from falling off.

[0039] After the electrical connection jack and the electrical connection plug are connected, the sealing door 401 is closed under the push of the spring sheet 402. Due to the existence of the notch 403, part of the tube body 302 remains outside, and the sealing door 401 can be completely closed to keep the inside of the square hole 200 clean.

[0040] When it is necessary to take it out, push the slider 501 to slide backward to knock open the sealing door 401, so that the squeezing plate 502 is close to the inclined plate 503. When squeezing the inclined plate 503, the plate body 303 is close to the connector sub-body 301, so that the one-way tooth 304 leaves the one-way tooth groove 305. The snap connection is released, and the connector sub-body 301 can be pulled out.

[0041] The above shows and describes the basic principles, main features and advantages of the utility model. Those skilled in the art should understand that the utility model is not limited by the above embodiments. The above embodiments and descriptions are only for explaining the principles of the utility model. Without departing from the spirit and scope of the utility model, the utility model may have various changes and improvements, which fall within the scope of the utility model to be protected. The scope of protection claimed by the utility model is defined by the attached claims and their equivalents.
