[0025] Refer to Figures 1-8, the present invention provides a high-voltage wire connector, which includes a male head 1 and a female head 2. A sub-head 3 is slidably installed in the male head 1, and a first conductive component 4 that can slide relative to each other is installed between the male head 1 and the sub-head 3. The female head 2 is installed with a second conductive component 5. During use, the male head 1 is inserted into the female head 2 correspondingly, and there is no electrical contact during the insertion process. The male head 1 is provided with a safety mechanism 6 that is movably connected to the sub-head 3. When the male head 1 and the female head 2 are further inserted, the female head 2 will trigger the safety mechanism 6. As the female head 2 is pushed forward, the safety mechanism 6 can push the sub-head 3 in the male head 1 closer to the female head 2, and make the first conductive component 4 on the sub-head 3 dock with the second conductive component 5 on the female head 2 for electrical connection. When a short circuit occurs in the circuit, the safety mechanism 6 can control the separation of the sub-head 3 and the female head 2 to achieve an open circuit effect and timely avoid short-circuit damage; further, after the sub-head 3 and the female head 2 are separated, only by reconnecting the male head 1 and the female head 2 can the function of reconnecting and energizing be realized.

[0026] In the specific implementation manner, referring to Figure 2 , Figure 5 , Figure 7 , the male head 1 includes a connecting plate 11 and a plug-in member 12. The two ends of the plug-in member 12 are communicated. One end of the plug-in member 12 is detachably connected to one side of the connecting plate 11. A sliding rod 14 is connected in the plug-in member 12 on the connecting plate 11. A contact plate 13 is provided at the end of the plug-in member 12 away from the connecting plate 11. The sub-head 3 is slidably connected to the sliding rod 14 and is located in the plug-in member 12. A first elastic member 15 is sleeved on the sliding rod 14, and the two ends of the first elastic member 15 respectively abut against the sub-head 3 and the contact plate 13; in this solution, both sides of the sub-head 3 slide through the sliding rod 14. When the male head 1 and the female head 2 are docked, the sub-head 3 still has a moving space in the male head 1, which can meet the separation of the sub-head 3 and the female head 2. Under the action of the safety mechanism 6, the sub-head 3 will be pushed to move towards the female head 2 and compress the first elastic member 15; the contact plate 13 can provide a contact point for the first elastic member 15. There is a gap between the two contact plates 13, and the gap is sufficient for the second conductive component 5 of the female head 2 to be inserted into the male head 1 and complete the electrical connection function.

[0027] In the specific implementation manner, referring to Figure 4, the safety mechanism 6 is arranged on both sides of the connector 12 and protrudes from both sides of the connector 12. In the middle of both sides of the connector 12, a chute 121 is arranged which penetrates into the connector 12 and is parallel to the slide bar 14. On both sides of the sub-head 3, a slide column 31 is connected which penetrates through the chute 121 and extends into the safety mechanism 6. In this solution, in this solution, the movement control of the sub-head 3 is all controlled by the slide column 31, that is, controlling the movement of the slide column 31 can control the movement of the sub-head 3. The slide column 31 passes through the chute 121 from the male head 1 and penetrates into the safety mechanism 6. The safety mechanism 6 changes the position of the sub-head 3 relative to the male head 1 by controlling the position of the slide column 31 on the chute 121, thereby realizing the function that the sub-head 3 can be inserted into the female head 2.

[0028] In the specific implementation manner, refer to Figure 4 , a rotating rod 61 is rotatably installed on one side of the chute 121 in the safety mechanism 6. The rotating rod 61 is provided with a strip-shaped groove 611. The part of the slide column 31 that penetrates into the safety mechanism 6 is located in the strip-shaped groove 611. A hook member 64 is rotatably installed on the side of the rotating rod 61 close to the connecting plate 11. A baffle 65 connected to the connector 12 is arranged on the side of the hook member 64. A transverse groove 63 is arranged between the baffle 65 and the hook member 64. A guide rod 66 is installed between the baffle 65 and the hook member 64. A second elastic member 67 is sleeved on the guide rod 66. The two ends of the second elastic member 67 respectively abut against the baffle 65 and the hook member 64. A hook body 68 is arranged on the side of the rotating rod 61 close to the hook member 64. The end of the hook body 68 can be hooked with the end of the hook member 64. An opening is arranged on the side of the safety mechanism 6. In this solution, the width of the safety mechanism 6 is limited, and a part of the rotating rod 61 will protrude from the opening on the side of the safety mechanism 6 to the outside. When the female head 2 is docked with the male head 1, the female head 2 will push the part of the rotating rod 61 protruding from the safety mechanism 6 and cause it to rotate like a lever, and make the rotating rod 61 completely retracted into the safety mechanism 6 after rotation; further, during the rotation of the rotating rod 61, the slide column 31 in its strip-shaped groove 611 will be driven, and the slide column 31 will slide along the chute 121 and drive the sub-head 3 to dock with the female head 2; during this process, when the rotating rod 61 rotates to a certain extent, the hook body 68 on the rotating rod 61 will be hooked with the hook member 64. At this time, the rotating rod 61 will always maintain this state, thereby restricting the movement of the sub-head 3; the hook member 64 has a certain rotating effect. When the hook member 64 rotates counterclockwise, the hook member 64 can immediately disengage the hook body 68. The second elastic member 67 always has a thrust, pushing the end of the hook member 64 away from the hook body 68, so as to maintain the hooking effect between the hook member 64 and the hook body 68.

[0029] In a further implementation manner, refer to Figure 4, a magnetic rod 70 is rotatably installed at one end of the hook member 64 away from the rotating rod 61. A coil 71 parallel to the first conductive component 4 is arranged in the safety mechanism 6. The magnetic rod 70 passes through the coil 71 and its end is located in the chute 121 of the baffle 65. In this solution, combined with the above solution, when a short circuit occurs in the circuit, although the coil 71 is in parallel, it will still step up the voltage, the magnetic force in the coil 71 will increase, the coil 71 will pull the magnetic rod 70 and overcome the elastic force of the second elastic member 67, causing the hook member 64 to rotate, and at this time the hook body 68 will be disengaged from the hook member 64. Further, the coil 71 needs to be connected in series with a resistor to avoid damage to the coil 71.

[0030] In a further embodiment, referring to Figure 3 , Figure 6 , Figure 8 , a slot 21 for inserting the safety mechanism 6 is arranged in the female head 2, and an arc slot 211 is arranged corresponding to the opening in the slot 21. This solution operates in combination with the above solution. Due to the limitation of the internal width of the female head 2, the rotating rod 61 will be blocked by the housing of the female head 2 and cannot rebound. Therefore, the arc slot 211 is provided to solve this problem. Before the female head 2 is completely docked with the male head 1, the rotating rod 61 will be hooked to the hook member 64, and the rotating rod 61 will be completely inside the safety mechanism 6 to avoid hindering the continuous movement of the female head 2. After the female head 2 moves a certain distance, it is completely docked with the male head 1. At this time, the position of the arc slot 211 corresponds to the opening, providing a rotation space for the rotating rod 61. When the hook member 64 is disengaged from the hook body 68, the rotating rod 61 can be unlocked, and the first elastic member 15 will quickly push the sub-head 3 away from the female head 2, realizing the disengagement effect of the sub-head 3 from the female head 2, and vice versa driving the rotating rod 61 to return to the state before installation.

[0031] In a specific embodiment, referring to Figure 4 , a groove extending inward is arranged at one end of the rotating rod 61 away from the strip-shaped groove 611. An extension member 613 is slidably installed in the groove, and a third elastic member is installed in the groove. Two ends of the third elastic member respectively abut against the extension member 613 and the inner wall of the groove. In this solution, the extension member 613 can expand and contract relative to the rotating rod 61, and after expansion and contraction, it can be completely placed inside the safety mechanism 6. When the female head 2 is disengaged from the male head 1, the arc slot 211 will gradually squeeze the extension member 613 to move into the groove to avoid hindering the disengagement of the female head 2 from the male head 1.

[0032] In a specific embodiment, referring to Figure 5, clamping members 8 are rotatably installed on both sides of the connecting plate 11. The clamping members 8 are provided with arc-shaped guide rails 81. Both sides of the female head 2 are provided with first rod bodies 212 that match the arc-shaped guide rails 81. After the clamping members 8 rotate, the distance between the first rod bodies 212 and the rotation axis of the clamping members 8 can be changed; in this solution, when the male head 1 is docked with the female head 2, the first rod bodies 212 on the side of the female head 2 will be located at the starting end of the arc-shaped guide rail 81, and then the clamping members 8 are rotated. The radius of the arc-shaped guide rail 81 from the starting end to the ending end to the rotation axis of the clamping member 8 gradually decreases. Therefore, during the rotation of the clamping member 8, it can promote the docking of the female head 2 to the male head 1, and vice versa for separation.

[0033] In a further implementation manner, referring to Figure 5 , Figure 6 , the clamping member 8 is connected with a second rod body 214, and a limit hook 213 is arranged above the female head 2. The second rod body 214 is clamped with the limit hook 213 to restrict rotation; in this solution, after the clamping member 8 rotates, its second rod body 214 is located within the limit hook 213, which can prevent the clamping member 8 from rotating, and further restrict the separation of the female head 2 and the male head 1.

[0034] In a specific implementation manner, referring to Figure 7 , the first conductive component includes a wiring member 41 and a metal column 42. The metal column 42 is connected through the sub-head 3. The wiring member 41 is connected to the connecting plate 11. The metal column 42 is slidably connected to the wiring member 41, and the metal column 42 can be in contact with the second conductive component 5 for conduction; in this solution, the metal column 42 is installed in the sub-head 3, its wiring member 41 is installed in the male head 1, its wiring member 41 is a tube body, and its metal column 42 can slide relative to the wiring member 41 to achieve the function of elongation or shortening, so as to cope with the sliding length of the sub-head 3.

[0035] The above is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present invention, according to the technical solution of the present invention and its inventive concept, makes equivalent substitutions or changes, and should be covered by the protection scope of the present invention.
