When the male assembly 20 is butted with the female assembly 10, the third connecting piece 22 is butted against the first connecting piece 12, the third connecting piece 22 pushes the first connecting piece 12 to move, so that the first connecting piece 12 is separated from the second connecting piece 13, and the first connecting piece 12 is disconnected from the second connecting piece 13; meanwhile, the fourth connecting member 23 gradually moves toward the second connecting member 13 and finally abuts against the second connecting member 13, so that the fourth connecting member 23 is conducted with the second connecting member 13. The third connecting member 22 is spaced apart from the fourth connecting member 23, so that the third connecting member 22 is prevented from contacting the fourth connecting member 23. When the male head assembly 20 is not butted with the female head assembly 10, the first connecting piece 12 and the second connecting piece 13 on the female head assembly 10 are butted, and the first connecting piece 12 and the second connecting piece 13 are conducted; after the male connector assembly 20 is connected with the female connector assembly 10, the third connecting member 22 abuts against the first connecting member 12 to push the first connecting member 12 to separate from the second connecting member 13, so that the first connecting member 12 is disconnected from the second connecting member 13, meanwhile, the third connecting member 22 abuts against and is communicated with the first connecting member 12, and the fourth connecting member 23 abuts against and is communicated with the second connecting member 13.

In the process of butt joint of the male assembly 20 and the female assembly 10, the first through hole can play a role in positioning and guiding the third connecting piece 22 to push against the first connecting piece 12, so that the third connecting piece 22 is smoothly connected with the first connecting piece 12, and the first connecting piece 12 is smoothly disconnected with the second connecting piece 13.
The third connector 22 and the fourth connector 23 may be fixed in the second base 21 or movably disposed in the second base 21, as long as it can be ensured that when the male assembly 20 is butted with the female assembly 10, the third connector 22 can push the first connector 12, and the fourth connector 23 can be butted with the second connector 13. Of course, the second connecting member 13 may also be movably mounted in the first base 11, and the elastic member pushes the second connecting member 13, so that when the fourth connecting member 23 moves towards the second connecting member 13, the elastic member can push the second connecting member 13 to elastically abut against the fourth connecting member 23.

The first connecting piece 12 and the second connecting piece 13 are displaced in the first accommodating cavity, and the third connecting piece 22 and the fourth connecting piece 23 extend out of the second accommodating cavity, so that potential safety hazards caused by the fact that the first connecting piece 12 and the second connecting piece 13 are in an automatic conducting state can be avoided. When the male head assembly 20 is not butted with the female head assembly 10, the first connecting piece 12 is conducted with the second connecting piece 13, but is positioned in the first accommodating cavity, so that the first connecting piece is not easy to contact with the outside; the third connecting member 22 and the fourth connecting member 23 are not connected although they are extended.
Furthermore, the first elastic element 14 is a first spring sleeved on the first connecting element 12, one end of the first connecting element 12, which is close to the end abutting against the second connecting element 13, is provided with a step surface, one end of the first spring abuts against the step surface, and the other end of the first spring abuts against the inner wall of the first base 11. This enables the first connecting member 12 to move linearly, preventing the first connecting member 12 from being stuck when moving.
Further, please refer to fig. 2 and fig. 4 together, as an embodiment of the connection mechanism of the present invention, the fourth connection member 23 is movably connected to the second base 21, the male component 20 further includes a second elastic member 24, and the second elastic member 24 is used for pushing the fourth connection member 23, so that the fourth connection member 23 is elastically abutted to the second connection member 13. In the butt joint process of the male head assembly 20 and the female head assembly 10, the first elastic piece 14 pushes the first connecting piece 12 to abut against the third connecting piece 22, and the second elastic piece 24 pushes the fourth connecting piece 23 to abut against the second connecting piece 13, so that the requirements on the position accuracy of the second connecting piece 13 and the fourth connecting piece 23 are reduced, and the fourth connecting piece 23 can be tightly connected with the second connecting piece 13.
Further, referring to fig. 2 and fig. 4, as an embodiment of the connection mechanism of the present invention, an insulating member 25 is sleeved on the third connection member 22, and the fourth connection member 23 is located outside the insulating member 25. The insulating member 25 thus functions to insulate the third and fourth connection members 22 and 23 and prevent a short circuit between the third and fourth connection members 22 and 23. The fourth connecting member 23 may be fixed to the insulating member 25, or may be movably connected to the insulating member 25; the insulating member 25 may be fixed to the third connecting member 22 or may be movably connected to the third connecting member 22.
Specifically, the insulator 25 has a tubular shape, and one end of the third connector 22 near the first connector 12 extends out of the insulator 25. This allows the first connector 12 to be electrically connected to the third connector 22 when the third connector 22 abuts against the first connector 12.
More specifically, one end of the insulating member 25 away from the second connecting member 13 is provided with a flange 251 for stopping the fourth connecting member 23, and the third connecting member 22 is provided with a boss 221 for stopping the insulating member 25. Therefore, when the third connecting part 22 moves towards the first connecting part 12, the relative movement of the fourth connecting part 23 and the third connecting part 22 can be prevented from causing the failure of the insulating part 25, and the function of supporting the fourth connecting part 23 can be achieved. On the other hand, when the fourth connecting part 23 is subjected to resistance, the third connecting part 22 can be pushed to move together, and the first elastic part 14 is prevented from being damaged.
Further, one end of the second elastic member 24 abuts against the third link 22, and the other end of the second elastic member 24 abuts against the inner wall of the second base 21. The second elastic element 24 is thus able to simultaneously push the third connecting element 22, the insulating element 25 and the fourth connecting element 23 into motion, so that the fourth connecting element 23 abuts against the second connecting element 13. The elastic force of the second elastic element 24 is greater than the elastic force of the first elastic element 14, and when the third connecting element 22 abuts against the first connecting element 12, the third connecting element 22 can smoothly push the first connecting element 12 to separate from the second connecting element 13, and meanwhile, the fourth connecting element 23 can tightly abut against the second connecting element 13. Therefore, in a complex working environment, through the mutual matching of the first elastic element and the second elastic element, poor contact between the first connecting element 12 and the third connecting element 22 and between the second connecting element 13 and the fourth connecting element 23 caused by vibration and the like in the environment is avoided. Moreover, when the external circuit device is switched, the first connecting piece 12 and the second connecting piece 22 are disconnected, and then the second connecting piece 13 and the fourth connecting piece 23 are connected, so that the function of protecting the circuit can be achieved.
Specifically, the second connecting member 13 is a second spring sleeved on the third connecting member 22. One end of the second spring abuts against the boss 221, and the other end of the second spring abuts against the inner wall of the second accommodating cavity. This enables the third link 22 to be guided in movement by the second spring.
Preferably, the stroke of the fourth connector 23 in the second accommodating cavity is smaller than the stroke of the third connector 22 pushing the first connector 12 in the first accommodating cavity when the male assembly 20 is butted with the female assembly 10. Namely: when the fourth link 23 is pushed to move, the maximum distance of movement of the fourth link 23 is smaller than the maximum distance of movement of the third link 22 pushing the first link 12. This makes it possible to avoid the fourth connector 23 from coming into contact with the second connector 13 without separating the first connector 12 and the second connector 22 when the male connector assembly 20 is mated with the female connector assembly 10 even when the first connector 12 is jammed, thereby avoiding causing a safety accident.
