[0025] This embodiment provides a highly sealed connector with stable connection, as shown in the attached figure. Figures 1-9 As shown, the device includes a socket 1 and a plug 2. The socket 1 is externally protected by a sheath structure, which includes an outer tube 6, heat-conducting plates 7, a cavity 8, and heat dissipation holes 9. Several heat-conducting plates 7 are arranged parallel to each other and fixedly connected to the inner surface of the outer tube 6. Each heat-conducting plate 7 abuts against the outer surface of the socket 1, with one end of the plate away from the socket 1 passing through the cavity 8. The cavity 8 is located inside the outer tube 6, and the heat dissipation holes 9 are located on the outer surface of the outer tube 6 and communicate with the cavity 8. Two sheath structures are used, each abutting against the plug 2. On both sides of the socket 1, sealing strips 10 are fixedly connected to both ends of one outer sleeve 6 near the other outer sleeve 6. A sealing groove 11 is opened at the corresponding part of the other outer sleeve 6 and the sealing strip 10, and the sealing strip 10 is inserted into the corresponding sealing groove 11. After the two sleeve structures are fitted onto the outside of the socket 1, the multiple heat-conducting plates 7 in the two sleeve structures can contact the outside of the socket 1, thereby effectively conducting the heat generated by the socket 1 during use and conducting the heat to the cavity 8. The cavity 8 is connected to the outside through the heat dissipation hole 9, thus ensuring that the connector has a good heat dissipation effect.

[0026] The outer surface of the socket 1 is fixedly connected with a limiting plate 12 for limiting and fixing it. There are several limiting plates 12, and each limiting plate 12 is clamped between two adjacent heat-conducting plates 7, which can keep the relative position between the socket 1 and the outer tube 6 fixed.

[0027] One end of the enclosure structure is threadedly connected to a locking ring 3 that can lock its end. A spring tube 4 is located on the side of the locking ring 3 away from the enclosure structure. The locking ring 3 can fix the two enclosure structures near the wire end of the socket 1. Simultaneously, the wire of the socket 1 can pass through the inside of the spring tube 4. The spring tube 4 can wrap around the outside of the wire according to its diameter, thus providing good protection for the wire portion at the end of the socket 1, preventing external water or dust from entering the outer tube from the wire portion at the end of the socket 1, improving the sealing performance of the connector; Socket 1 and The connection part of the sleeve structure away from the locking ring 3 is provided with a first sealing structure. The first sealing structure includes a first sealing ring 13 and a first annular groove 14. The first sealing ring 13 is fixedly connected to the side of the socket 1 near the plug fixing structure and in contact with the outer sleeve 6. The two outer sleeves 6 are each provided with a first annular groove 14 on the side near the plug fixing structure, and the two first annular grooves 14 can be joined together to form a closed ring. The first sealing ring 13 is inserted into the inside of the two first annular grooves 14, which can improve the sealing of the connection part between the socket 1 and the two outer sleeves 6.

[0028] The end of the sealing structure away from the locking ring 3 is threadedly connected to a sealing sleeve 5, and a plug fixing structure for fixing the plug 2 is installed inside the sealing sleeve 5. The plug 2 is located inside the plug fixing structure, and its exposed end is inserted into the socket 1. The plug fixing structure includes a fixing sleeve 15 and an internally threaded tube 16. There are two fixing sleeves 15, and the two fixing sleeves 15 are interlocked on the outside of the plug 2. A sealing strip and a sealing groove are also provided at the joint of the two fixing sleeves 15 to ensure a tight connection between the two fixing sleeves 15. The internally threaded tube 16 is threaded onto the outside of the two fixing sleeves 15. The end of the internally threaded tube 16 near the sealing sleeve 5 can be pressed against it, and the end away from the sealing sleeve 5 can press against the tail of the plug 2. The sealing sleeve 5 is fitted over the outside of the two fixed sleeves 15 and is threadedly connected to the outside of the two outer sleeves 6. After the plug 2 is inserted into the socket 1, the sealing sleeve 5 is threadedly connected to the end of the two outer sleeves 6 near the fixed sleeve 15, which can keep the relative position between the plug 2 and the socket 1 fixed and make the two tightly connected. At the same time, the sealing sleeve 6 can provide further protection for the connection between the plug 2 and the socket 1, and can effectively prevent external impurities from entering the interior of the socket 1.

[0029] A second sealing structure is provided at the connection between the sealing sleeve 5 and the plug fixing structure. The second sealing structure includes a second sealing ring 17 and a second annular groove 18. The second sealing ring 17 is fixedly connected to the inner surface of the sealing sleeve 5. The two fixing sleeves 15 are provided with second annular grooves 18 at the parts where they are in contact with the inner surface of the sealing sleeve 5. The second sealing ring 17 can be inserted into the two second annular grooves 18, which can improve the sealing performance of the contact parts between the sealing sleeve 5 and the fixing sleeve 15.

[0030] In summary, this stable, high-sealing connector can be used in the following ways:

[0031] 1. Fit the two outer sleeves 6 onto the outside of the socket 1, and then connect the locking ring 3 to the end of the two outer sleeves 6 near the tail of the socket 1 by thread. The elastic tube 4 is wrapped around the outside of the wire of the socket 1.

[0032] 2. Then, the two fixing sleeves 15 are spliced ​​together and fitted onto the outside of the plug 2, the sealing sleeve 5 is fitted onto the outside of the two fixing sleeves 15, and the internal threaded tube 16 is threaded onto the outside of the two fixing sleeves 15.

[0033] 3. Insert the plug end of plug 2 into socket 1 and rotate the threaded sleeve 5 so that its threads are connected to the two outer sleeves 6 at their closest ends. This can lock the two outer sleeves 6 to the outside of socket 1 and keep the relative positions of socket 1 and plug 2 fixed, forming a fixed whole. This can effectively prevent plug 2 from loosening and ensure the sealing of the connection between the two.
