Description

Technical Field

[0001] The utility model relates to the technical field of marine electric connectors, in particular to a marine electric connector with annular contacts. Background Art

[0002] Since the ship's hull and the devices inside the ship will shake when it is on the water, the electrical connector on the ship will gradually detach under long-term shaking. In order to prevent the ship's electrical connector from detaching during the shaking process, a ship's electrical connector with an annular contact finger is proposed.

[0003] There is a marine electrical connector with an annular contact finger (its authorization announcement number is: CN217691936U), which connects and fixes the plug shaft and the socket through the cooperation of the first limiting structure and the second limiting structure during the insertion of the plug shaft.

[0004] However, this type of marine electrical connector with annular contacts has some shortcomings during actual use: when the plug shaft is successfully inserted into the socket to the left, the cooperation of the first limiting structure and the second limiting structure cannot achieve a stable fixed connection between the plug shaft and the socket. When the plug shaft generates a force to the right due to shaking, there is still a risk of separation between the plug shaft and the socket, causing abnormal operation of the marine electrical connector. Therefore, we have proposed the present utility model to solve the above problems. Utility Model Content

[0013] Compared with the prior art, the beneficial effects of the present invention are:

[0021] Reference Figure 1-4A marine electrical connector with an annular contact finger includes a socket 1 and a plug shaft 2. The socket 1 is provided with a slot 3, and the plug shaft 2 is provided with a contact finger support foot 4. The contact finger support foot 4 on the plug shaft 2 is inserted into the slot 3 of the socket 1. The contact finger support foot 4 is respectively provided with a plurality of positioning grooves 5. The socket 1 is respectively provided with a plurality of lifting movable cavities 6. The plurality of lifting movable cavities 6 are each movably installed with a movable block 7. Both sides of the movable block 7 are provided with a semicircular groove 8. Ball bearings 9 are rotatably installed on the plurality of movable blocks 7. Parts of the multiple balls 9 pass through the slot 3 and rest against the corresponding positioning slots 5. Side grooves 10 are provided in the multiple lifting and lowering cavities 6. The side grooves 10 are provided with connection and positioning mechanisms for the two semicircular grooves 8. Multiple translational activity cavities 13 are provided in the socket 1. Elastic connection mechanisms for the corresponding connection and positioning mechanisms are provided in the multiple translational activity cavities 13. An annular groove 18 is provided on the outer wall of the socket 1. A connecting member mechanism for the elastic connection mechanism is provided in the annular groove 18.

[0022] Furthermore, multiple positioning grooves 5 are distributed in a circular array, and the balls 9 are arranged corresponding to the positioning grooves 5; by the multiple balls 9 extending out and resting in the corresponding positioning grooves 5, a stable connection between the socket 1 and the plug shaft 2 is achieved.

[0023] Furthermore, the connection and positioning mechanism includes a side frame 11 and a first circular plate 12. Two side frames 11 are movably installed in the side groove 10 of the lifting movable chamber 6. Two first circular plates 12 are fixedly installed on the side where the two side frames 11 are close to each other. The corresponding parts of the first circular plates 12 are inserted into the corresponding semicircular grooves 8 on the movable block 7; when the corresponding first circular plates 12 parts on the two side frames 11 are inserted into the corresponding semicircular grooves 8 on the movable block 7, the corresponding movable block 7 is limited and fixed.

[0024] Specifically, the side frame 11 is arranged in a U-shaped structure, and the inner wall of the side frame 11 is in contact with the outer wall of the movable block 7, so that the side frame 11 can slide back and forth horizontally on the outer wall of the movable block 7.

[0025] Furthermore, the elastic connection mechanism includes a second circular plate 14, a first connecting rod 15, a second connecting rod 16 and a spring 17. The second circular plate 14 is movably installed in the translationally active cavity 13, and one end of the first connecting rod 15 is fixedly installed on one side of the second circular plate 14. The other end of the first connecting rod 15 passes through the corresponding side groove 10 and is fixedly installed on one side of the corresponding first circular plate 12. One end of the second connecting rod 16 is fixedly installed on the other side of the second circular plate 14, and the other end of the second connecting rod 16 passes through the outside of the socket 1. One end of the spring 17 is fixedly installed on one side of the second circular plate 14, and the other end of the spring 17 is fixedly installed on one side of the inner wall of the translationally active cavity 13; when the annular sleeve 19 is not moved, under the elastic force of multiple springs 17, the multiple second circular plates 14 are respectively pressed against the left side wall of the corresponding translationally active cavity 13.

[0026] Specifically, the connecting member mechanism includes an annular sleeve 19 and a connecting plate 20. The annular sleeve 19 is movably installed in the annular groove 18. Multiple connecting plates 20 are fixedly installed on one side of the annular sleeve 19. One end of the multiple connecting plates 20 passes through the outside of the socket 1 and is fixedly connected to the corresponding second connecting rods 16 respectively; by pushing the annular sleeve 19 outward, the multiple connecting plates 20 can synchronously drive the multiple second connecting rods 16 to move.

[0027] During use: When connecting the socket 1 and the plug shaft 2, the installer pushes the circular sleeve 19 in the circular groove 18 outward, so that the multiple connecting plates 20 synchronously drive the corresponding second connecting rod 16, the second circular plate 14, the first connecting rod 15, the two first circular plates 12 and the two side frames 11 to move to the right. At this time, the multiple springs 17 are deformed and compressed under the force, so that the corresponding two first circular plates 12 are separated from the lifting activity cavity 6. After that, the contact finger support foot 4 at one end of the plug shaft 2 is inserted into the slot 3 of the socket 1. When the contact finger support foot 4 on the plug shaft 2 squeezes the multiple balls 9 to the left, the multiple balls 9 are pushed to retract synchronously into the corresponding lifting activity cavity 6, driving the multiple movable blocks 7 to move in the corresponding lifting activity cavity 6 respectively. The plurality of first circular plates 12 are moved to the left synchronously under the elastic force of the plurality of springs 17, so that the corresponding first circular plates 12 are respectively inserted into the corresponding semicircular grooves 8 on the corresponding movable blocks 7, thereby limiting and fixing the positions of the plurality of movable blocks 7. The balls 9 on the plurality of movable blocks 7 are respectively extended and pressed against the corresponding positioning grooves 5, thereby achieving a stable connection between the socket 1 and the plug shaft 2. The marine electrical connector in this case can achieve a stable fixed connection between the socket 1 and the plug shaft 2, avoid the separation of the marine electrical connectors due to shaking, and ensure the normal operation of the marine electrical connector.
