[0019] 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.

[0020] Please see Figure 1-3 This utility model provides a technical solution for a male cable connector: it includes an outer connector housing 1, an inner connector mounting component 2 fixedly disposed inside the outer connector housing 1, a terminal connection groove 3 disposed inside the inner connector mounting component 2, a connecting terminal 4 fixedly disposed inside the terminal connection groove 3, a threaded connection part 5 fixedly disposed on one side of the inner connector mounting component 2, a cable connection wire 6 fixedly welded inside the threaded connection part 5, the cable connection wire 6 being electrically connected to the connecting terminal 4, and a connector fixing assembly installed inside the outer connector housing 1. The connector fixing assembly includes a movable pressure plate 7, an intermediate connecting ring 8, and a rotating component 9. One end of the movable pressure plate 7 is connected to the intermediate connecting ring 8, and the other side of the intermediate connecting ring 8 is rotatably connected to the rotating component 9.

[0021] In this embodiment, after the male cable connector is inserted into the female interface, the rotating component 9 is rotated so that the rotating component 9 can move left and right in the threaded connection part 5. On the other side of the rotating component 9 through the intermediate connecting ring 8, the connecting rod 11 will be pushed to move, so that the movable pressure plate 7 can abut against the outer wall of the female interface.

[0022] Furthermore, the outer connector housing 1 has a groove 10, the movable pressure plate 7 is installed in the groove 10, the bottom of the movable pressure plate 7 is connected to a connecting rod 11, and the two ends of the connecting rod 11 are provided with rotating shafts.

[0023] In this embodiment, the connecting rod 11 will drive the movable pressure plate 7 to move up and down in the groove 10, thereby making the male cable connector fit more tightly.

[0024] Furthermore, the connecting rod 11 is provided in three sets, of which the bottom of two sets of connecting rod 11 is movably connected to the inner connector mounting part 2, and the bottom of the other set of connecting rod 11 is movably connected to one side of the middle connecting ring 8.

[0025] In this embodiment, the bottom of two sets of connecting rods 11 mainly serves as support, while the other set of connecting rods 11 is used for control.

[0026] Furthermore, the intermediate connecting ring 8 is sleeved on the inner connector mounting part 2, and the inner connector mounting part 2 is slidably connected to the intermediate connecting ring 8.

[0027] In this embodiment, the movable pressure plate 7 is controlled by controlling the left and right movement of the intermediate connecting ring 8.

[0028] Furthermore, the rotating component 9 is movably mounted on the threaded connection portion 5, and the rotating component 9 is threadedly connected to the threaded connection portion 5.

[0029] Furthermore, a connecting slider 12 is fixedly provided on one side of the intermediate connecting ring 8, and a groove 13 is provided inside the threaded connecting part 5, and the connecting slider 12 is movably installed in the groove 13 of the threaded connecting part 5.

[0030] In this embodiment, since the intermediate connecting ring 8 and the rotating component 9 are movably connected by the connecting slider 12, when the rotating component 9 moves to one side, it will push the intermediate connecting ring 8 to move to the same side.

[0031] Furthermore, a rubber flexible plate 14 is fixedly provided on the top of the movable pressure plate 7. The rubber flexible plate 14 can improve the fit of the male cable connector and prevent slippage. Anti-slip protrusions are provided on the outside of the threaded connection part 5 to improve friction.

[0032] Working principle: This utility model has a connector fixing assembly installed inside the outer connector housing 1. After the male cable connector is inserted into the female interface, rotating the rotating part 9 allows it to move left and right in the threaded connection part 5. Since the intermediate connecting ring 8 and the rotating part 9 are movably connected by the connecting slider 12, when the rotating part 9 moves to one side, it pushes the intermediate connecting ring 8 to move to the same side. The other side of the intermediate connecting ring 8 pushes the connecting rod 11 to move, and the connecting rod 11 drives the movable pressure plate 7 to move up and down, so that the movable pressure plate 7 can abut against the outer wall of the female interface. When disassembling, rotating the rotating part 9 in the opposite direction can achieve separation. This structure can improve the stability of the male cable connector connection and prevent the male cable connector from loosening. It has the advantages of being easy to use and having good performance.
