DETAILED DESCRIPTION

[0023] The technical solution of the present invention will be clearly and completely described below in conjunction with the accompanying drawings. The preferred embodiments in the description are only used as examples. All other embodiments obtained by those skilled in the art without making any creative work are within the scope of protection of the present invention.

[0024] like Figures 1-4 As shown, this specific embodiment adopts the following technical solution: it includes a connector 1, a conductive plug 2 and a docking head 3. Several conductive plugs 2 are arranged in a ring with equal intervals in the connector 1. The docking head 3 is provided on the right side of the connector 1. The docking head 3 is provided with a docking socket 4 that matches the conductive plug 2;

[0025] It also contains:

[0026] A movable plate 5 is movably arranged in the connector 1 and movably sleeved on the ends of several conductive plug rods 2. A disconnecting moisture-proof mechanism 6 is provided in the connector 1 and on the butt joint 3. Docking strips 15 are fixedly provided on the upper and lower sides of the butt joint 3 by bolts. A strip groove 16 that cooperates with the butt joint 15 is provided on the inner ring wall of the connector 1. A movable block 17 is movably provided in the strip groove 16. The movable block 17 is fixedly connected to the side wall of the movable plate 5 by bolts. The butt joint 15 can provide a connection guide when the connector 1 is connected to the butt joint 3;

[0027] The movable cylinder 7 is fixed to the left side wall of the movable plate 5 by bolts. The movable cylinder 7 is movably arranged inside the connector 1 and is located outside the plurality of conductive plug rods 2. A spring 8 is movably sleeved on the movable cylinder 7. The two ends of the spring 8 are respectively connected to the movable plate 5 and the inner wall of the connector 1;

[0028] The threaded sleeve 9 is movably sleeved on the connector 1, and the butt joint 3 is provided with a thread 10 that cooperates with the threaded sleeve 9. The right end of the connector 1 is fixedly sleeved with a No. 1 limiting ring 11 that cooperates with the threaded sleeve 9. The connector 1 is located on the left side of the threaded sleeve 9 and is fixedly sleeved with a No. 2 limiting ring 18. Through the cooperation of the No. 1 limiting ring 11 and the No. 2 limiting ring 18, the threaded sleeve 9 can be limited to prevent the threaded sleeve 9 from detaching from the connector 1. The butt joint 3 is located on the left side of the thread 10 and is fixedly sleeved with a sealing ring 14. The sealing ring 14 cooperates and conflicts with the No. 1 limiting ring 11. When the connector 1 is connected to the butt joint 3 and the threaded sleeve 9 is sleeved on the butt joint 3 through the thread 10, the sealing ring 14 can conflict with the No. 1 limiting ring 11, thereby improving the sealing of the connection between the connector 1 and the butt joint 3 and preventing the entry of water vapor into the connector 1 and the butt joint 3 in this state;

[0029] The disconnection moisture-proof mechanism 6 comprises:

[0030] A first baffle 6-1 is movably disposed at the internal opening of the connector 1 and is rotatably connected to the right side wall of the movable plate 5 via a thrust ball bearing. Guide blocks 6-2 are fixedly disposed on both the front and rear sides of the outer ring wall of the first baffle 6-1. The guide blocks 6-2 are movably disposed in guide grooves 12 provided on the inner ring wall of the connector 1.

[0031] The second baffle 6-3 is rotatably arranged at the left end of the docking joint 3 through a thrust ball bearing. The first baffle 6-1 and the second baffle 6-3 are provided with several through holes with evenly rounded corners. The through holes are staggered and matched with the conductive plug 2.

[0032] The rotating shaft 6-4 is rotatably inserted into the docking joint 3 through a bearing and a torsion spring. The left end of the rotating shaft 6-4 passes through the docking joint 3 and is fixedly connected to the second baffle 6-3 by a bolt. An insert block 6-5 is fixedly provided on the left side wall of the second baffle 6-3, and a groove 13 that cooperates with the insert block 6-5 is opened on the right side wall of the first baffle 6-1.

[0033] When using the present invention, when the connector 1 and the docking connector 3 are in the disconnected state, the movable plate 5 and the No. 1 baffle 6-1 can seal the opening of the connector 1 to prevent moisture from entering the connector 1 and affecting the conductive plug 2 in the connector 1. The No. 2 baffle 6-3 can seal the docking jack 4 to prevent moisture from entering the docking jack 4 and causing short circuits. When connecting the connector 1 and the docking connector 3, the plug 6-5 is inserted into the groove 13, and the connector 1 and the docking connector 3 are moved in relative directions so that the docking connector 3 is inserted into the connector 1. At this time, the No. 1 baffle 6-1 and the movable plate 5 will move toward the inside of the connector 1, and the conductive plug 2 in the connector 1 will be blocked. The guide block 6-2 will move in the guide groove 12 and drive the No. 1 baffle 6-1 to rotate a certain angle. The No. 1 baffle 6-1 drives the No. 2 baffle 6-3 to rotate a certain angle synchronously through the plug block 6-5, so that the through holes on the No. 1 baffle 6-1 and the No. 2 baffle 6-3 can be aligned with the conductive plug rod 2 and the docking socket 4. Then the conductive plug rod 2 can pass through the through hole and be inserted into the docking socket 4, and the spring 8 is in a compressed state at this time. Then the threaded sleeve 9 can be moved to the right and rotated, so that the inner wall of the threaded sleeve 9 contacts the No. 1 limit ring 11, and the threaded sleeve 9 can be screwed on the docking joint 3 through the thread 10, so as to achieve locking of the connector 1 and the docking joint 3 in the connected state.

[0034] Compared with the prior art, the beneficial effects of the present invention are:

[0035] Through the cooperation of the movable plate 5, the disconnect moisture-proof mechanism 6, the movable cylinder 7 and the spring 8, when the connector 1 and the docking connector 3 are disconnected and idle, the internal conductive plug rod 2 and the docking socket 4 can be protected to prevent moisture from entering and causing a short circuit.

[0036] When the connector 1 is connected to the butt joint 3 and the threaded sleeve 9 is sleeved on the butt joint 3 through the thread 10, the sealing ring 14 can come into contact with the No. 1 limiting ring 11, thereby improving the sealing performance of the connection between the connector 1 and the butt joint 3 and preventing moisture from entering the connector 1 and the butt joint 3 in this state.

[0037] For those skilled in the art, they can modify the technical solutions described in the aforementioned embodiments and make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present utility model should be included in the scope of protection of the present utility model.
