[0033] The technical solution of the present invention is further described below with reference to the accompanying drawings and through specific implementation methods.

[0034] Embodiment 1:

[0035] like Figures 1 to 5A plug-in connection device is shown, comprising a connection device body and a rotary lock 32, wherein a connecting conductor is arranged inside the connection device body, and the rotary lock 32 is arranged on the outside of the connection device body, and is used to lock the connection device with another connection device of the electrical connector, and the rotary lock 32 is connected to the connection device body through a rotating shaft 31, and the rotary lock 32 can rotate with the axis of the rotating shaft 31 as the rotation center line to switch between a locked position and an unlocked position.

[0036] In this embodiment, the connecting device body and the rotating shaft 31 are integrally formed, a rotating hole is provided in the middle of the rotating lock 32, and the rotating lock 32 is rotatably connected to the rotating shaft 31 through the rotating hole. The rotating hole can also be provided at one end of the rotating lock 32.

[0037] In other embodiments, the rotary lock buckle is integrally formed with the rotary shaft, the rotary shaft is located in the middle or one end of the rotary lock buckle, a rotary hole is provided on the connecting device body, and the rotary lock buckle is connected to the connecting device body by inserting the rotary shaft into the rotary hole.

[0038] In this embodiment, one end of the rotating lock 32 is configured as a locking hook 321, and the locking hook 321 can be engaged with the slot 21 of another connecting device of the electrical connector. The other end of the rotating lock 32 is configured as a locking handle 322. Driving the locking handle 322 can enable the locking hook 321 to be engaged with or disengaged from the slot 21 of another connecting device of the electrical connector.

[0039] In this embodiment, a connector 33 is provided on one side of the rotary lock 32, and a damping column 34 is provided on the connecting device body. The damping column 34 is located on the side of the connector 33 away from the rotary lock 32. When the rotary lock 32 is rotated to lock or unlock, the damping column 34 can abut against the connector 33 to increase the damping force of the rotary lock 32 to prevent the rotary lock 32 from excessive rotation.

[0040] In this embodiment, one end of the rotary lock buckle 32 having the locking hook 321 is configured to be elongated, so that the locking hook 321 is elastically deformed and reset after being inserted into the slot hole 21 of the other connecting device. During the process of inserting the locking hook 321 into the slot hole 21 of the other connecting device, the damping column 34 provides a damping force to the connecting body 33 and the rotary lock buckle 32, so that the end of the rotary lock buckle 32 having the locking hook 321 is elastically deformed, and when the locking hook 321 is completely engaged with the slot wall of the slot hole 21 of the other connecting device, the end of the rotary lock buckle 32 having the locking hook 321 is reset.

[0041] In this embodiment, the connecting body 33 is provided with a sliding groove group 331 , and the damping column 34 is provided with a convex bump group 341 . The sliding groove group 331 and the convex bump group 341 are slidably matched.

[0042] When it is necessary to unlock the connecting device from another connecting device of the electrical connector, the locking handle 322 is pressed clockwise, and the rotary lock buckle 32 rotates clockwise with the axis of the rotating shaft 31 as the rotation center line, and the locking hook 321 disengages from the slot 21 of the other connecting device of the electrical connector. At the same time, the slide groove group 331 and the convex bump group 341 slide relative to each other, and the convex bump group 341 of the damping column 34 abuts against the connecting body 33 and the rotary lock buckle 32 integrally provided with the connecting body 33, generating obvious vibration and sound to indicate that it has been unlocked, and at the same time, the damping column 34 limits the unlocking state of the rotary lock buckle 32 When it is necessary to lock the connecting device with another connecting device of the electrical connector, the locking handle 322 is pressed counterclockwise, and the rotating lock buckle 32 rotates counterclockwise with the axis of the rotating shaft 31 as the rotation center line, and the locking hook 321 engages the slot hole 21 of the other connecting device of the electrical connector. At the same time, the slide groove group 331 and the convex bump group 341 slide relative to each other, and the convex bump group 341 generates a damping force on the connecting body 33 and the rotating lock buckle 32 integrally provided with the connecting body 33, and generates obvious vibration and sound to indicate that it has been locked, and the limit position of the locking state of the rotating lock buckle 32 is limited by the damping column 34.

[0043] In other embodiments, a slide groove group is arranged on the damping column, and a convex bulge group is arranged on the connecting body. The slide groove group and the convex bulge group are slidingly matched to generate obvious vibration and sound when switching between locking and unlocking to prompt locking or unlocking.

[0044] In this embodiment, the connecting body 33 is provided with a bolt hole 332, and a screw is threadedly connected to another connecting device of the electrical connector through the bolt hole 332. When the connecting device and another connecting device of the electrical connector need to be locked for a long time, the connection stability is improved by threading the screw through the bolt hole 332 and the other connecting device of the electrical connector, thereby preventing the rotating lock buckle 32 from being subjected to external forces for a long time.

[0045] The connecting device body is provided with a baffle 35 which can cover a part of the rotating lock buckle 32 . When the rotating lock buckle 32 is rotated to a locking position or an unlocking position, the baffle 35 can expose different marks on the rotating lock buckle 32 .

[0046] In this embodiment, the side surfaces of the locking handle 322 and the connecting body 33 are both provided with anti-skid patterns to increase the friction force. When the side surface of the locking handle 322 with the anti-skid patterns is pressed, the locking hook 321 is engaged with the edge of the slot wall of the slot hole of the other connecting device; when the side surface of the connecting body 33 with the anti-skid patterns is pressed, the locking hook 321 is separated from the edge of the slot wall of the slot hole of the other connecting device.

[0047] In this embodiment, when the locking hook 321 is engaged with the slot 21 of another connecting device of the electrical connector, the baffle 35 covers the locking mark on the rotating lock 32 and exposes the unlocking mark, so as to prompt that unlocking will be achieved by rotating in the indicated direction; when the locking hook 321 is disengaged from the slot 21 of another connecting device of the electrical connector, the baffle 35 covers the unlocking mark on the rotating lock 32 and exposes the locking mark, so as to prompt that locking will be achieved by rotating in the indicated direction.

[0050] In this embodiment, the side surface of the female connection device 1 is provided with anti-slip stripes 11 to facilitate the insertion of the male connection device 2 into the female connection device 1 .

[0051] In this embodiment, a slot hole 21 is provided at one end of the male connecting device 2 that contacts the female connecting device 1, and the slot wall length of the slot hole 21 is less than or equal to the length from the locking hook 321 to the axis of the rotating shaft 31, so that the locking hook 321 can be snapped into the edge of the slot wall of the slot hole 21.

[0052] Before the female connecting device 1 and the male connecting device 2 are plugged together, the rotary lock 32 has been adjusted to a locked position on the female connecting device 1. During the plugging process of the female connecting device 1 and the male connecting device 2, the locking hook 321 presses against the groove wall of the groove hole 21, and the rotary lock 32 is elastically deformed by the damping force of the damping column 34. When the female connecting device 1 and the male connecting device 2 are fully plugged together, the elastic potential energy of the rotary lock 32 causes the locking hook 321 to automatically engage with the groove wall of the groove hole 21 to achieve automatic locking, and the rotary lock 32 releases the elastic potential energy and resets.

[0053] In other embodiments, the male connection device adopts the plug-in connection device described in the first embodiment, and the female connection device adopts another connection device of the electrical connector described in the first embodiment.

[0054] In other embodiments, the side of the male connection device is provided with anti-slip stripes to facilitate the insertion of the male connection device with the female connection device. Alternatively, the side of the male connection device and the side of the female connection device are both provided with the anti-slip stripes.

[0055] In other embodiments, a slot is provided at one end of the female connection device that contacts the male connection device, and the length of the slot wall of the slot is less than or equal to the length from the buckle hook to the axis of the rotating shaft, so that the buckle hook can be snapped onto the edge of the slot wall of the slot. Alternatively, the male connection device and the female connection device both use the plug-in connection device as described in Example 1, and the male connection device and the female connection device both have the slot at one end that contacts each other.

The other connecting device of the electrical connector is provided with two of the slots 21, and the two rotating locks 32 are respectively inserted into the two slots 21 for engagement, so as to improve stability.

[0057] In other embodiments, the rotating shaft 31 , the rotating lock 32 , the connecting body 33 , the damping column 34 , and the baffle 35 may be arranged in three groups, or four groups, or even more groups, to improve stability.
