DETAILED DESCRIPTION Example

[0017] Reference Figure 1-Figure 8 The present invention proposes a high-voltage wire connector, including a male head 1 and a female head 2, wherein a sub-head 3 is slidably installed in the male head 1, a first conductive component 4 that can slide against each other is installed between the male head 1 and the sub-head 3, and a second conductive component 5 is installed on the female head 2. When in use, the male head 1 is plugged into the female head 2, and no contact conduction is performed during the plugging 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 plugged into each other, 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 to approach the female head 2, and make the first conductive component 4 on the sub-head 3 and the second conductive component 5 on the female head 2 dock and conduct electricity. When the line is short-circuited, the safety mechanism 6 can control the sub-head 3 to be separated from the female head 2, so as to achieve a circuit-breaking effect and avoid short-circuit damage in time; further, after the sub-head 3 is separated from the female head 2, it is only necessary to re-plug the male head 1 and the female head 2 to achieve the effect of reconnecting and energizing.

[0018] In a specific implementation manner, refer to Figure 2 , Figure 5 , Figure 7The male connector 1 comprises a connecting plate 11 and a plug connector 12. The two ends of the plug connector 12 are connected. One end of the plug connector 12 is detachably connected to one side of the connecting plate 11. The connecting plate 11 is located in the plug connector 12 and is connected to a slide rod 14. The end of the plug connector 12 away from the connecting plate 11 is provided with a contact plate 13. The sub-head 3 is slidably connected to the slide rod 14 and is located in the plug connector 12. The slide rod 14 is sleeved with a first elastic member 15, and the two ends of the first elastic member 15 respectively contact the sub-head 3 and the contact plate 13. In this embodiment, Both sides of the sub-head 3 slide through the sliding rod 14. When the male head 1 is connected to the female head 2, the sub-head 3 still has room for movement inside the male head 1, which can meet the needs of the sub-head 3 and the female head 2 to separate. Under the action of the safety mechanism 6, the sub-head 3 will be pushed toward the female head 2 and compress the first elastic member 15; its contact plate 13 can provide a contact point for the first elastic member 15, and there is a gap between the two contact plates 13, which is enough for the second conductive component 5 of the female head 2 to be inserted into the male head 1 and complete the conductive connection.

[0019] In a specific implementation manner, refer 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. The middle part of both sides of the connector 12 is provided with a slide groove 121 that penetrates into the connector 12 and is parallel to the slide rod 14. Both sides of the sub-head 3 are connected with a slide column 31 that penetrates the slide groove 121 and extends into the safety mechanism 6; in this scheme, in this scheme, the movement control of the sub-head 3 is all controlled by the slide column 31, and the movement of the sub-head 3 can be controlled by controlling the movement of the slide column 31. The slide column 31 penetrates from the male head 1 through the slide groove 121 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 slide groove 121, thereby realizing the function that the sub-head 3 can be plugged into the female head 2.

[0020] In a specific implementation manner, refer to Figure 4, a rotating rod 61 is rotatably installed on one side of the slide groove 121 in the safety mechanism 6, and the rotating rod 61 is provided with a strip groove 611. The part of the slide column 31 that penetrates into the safety mechanism 6 is located in the strip groove 611. A hook member 64 is rotatably installed on the rotating rod 61 near the connecting plate 11. A baffle 65 connected to the plug-in member 12 is provided on the side of the hook member 64. A transverse groove 63 is provided between the baffle 65 and the hook member 64. A guide rod 66 is installed between the baffle 65 and the hook member 64. The guide rod 66 is sleeved with a second elastic member 67. The two ends of the second elastic member 67 respectively contact the baffle 65 and the hook member 64. A hook body 68 is provided on the side of the rotating rod 61 near the hook member 64. The hook body 68 can be hung with the end of the hook member 64, and an opening is provided on the side of the safety mechanism 6; in this scheme, the width of the safety mechanism 6 is limited, and a part of its rotating rod 61 will protrude from the opening on the side of the safety mechanism 6 to Externally, when the female head 2 is docked with the male head 1, the female head 2 will push the rotating rod 61 to protrude from the part of the safety mechanism 6 and cause the lever to rotate, and the rotating rod 61 will be completely stored in the safety mechanism 6 after rotation; further, during the rotation of the rotating rod 61, the sliding column 31 in the strip groove 611 will be driven, and the sliding column 31 will slide along the sliding groove 121 and drive the sub-head 3 to dock with the female head 2; in 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, and the rotating rod 61 will always maintain this state at this time, thereby restricting the movement of the sub-head 3; its hook member 64 has a certain rotation effect, and when the hook member 64 rotates counterclockwise, its hook member 64 will allow the hook body 68 to be disengaged, and the second elastic member 67 always has a thrust to push the hook member 64 away from one end of the hook body 68, so the hook member 64 will maintain the effect of hooking with the hook body 68.

[0021] In a further embodiment, reference is made 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 connected in parallel with the first conductive component 4 is arranged in the safety mechanism 6, the magnetic rod 70 passes through the coil 71 and the end is located in the slide groove 121 of the baffle 65; this scheme is used in combination with the above scheme, when a short circuit occurs in the line, although the coil 71 is in parallel, it will still increase the voltage, and the magnetic force in the coil 71 will increase, and the coil 71 will pull the magnetic rod 70 and overcome the elastic force of the second elastic member 67, so that the hook member 64 will rotate, and at this time the hook body 68 will be separated from the hook member 64; further, the coil 71 needs to be used with a series resistor to avoid damage to the coil 71.

[0022] In a further embodiment, reference is made to Figure 3 , Figure 6 , Figure 8, a slot 21 corresponding to the safety mechanism 6 is provided in the female head 2, and an arc groove 211 is provided at the corresponding opening in the slot 21; this scheme is combined with the above scheme, and due to the limitation of the internal width of the female head 2, its rotating rod 61 will be blocked by the shell of the female head 2 and cannot rebound, so the arc groove 211 is provided to solve the problem. Before the female head 2 is fully docked with the male head 1, the rotating rod 61 will be hooked with the hook member 64, and the rotating rod 61 will be completely in the safety mechanism 6 to avoid hindering the continued movement of the female head 2. The female head 2 will continue to move a certain distance before it is fully docked with the male head 1. At this time, the arc groove 211 corresponds to the position of 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 to move away from the female head 2, so as to achieve the effect of disengaging the sub-head 3 from the female head 2, and vice versa, drive the rotating rod 61 to restore the state before installation.

[0023] In a specific embodiment, refer to Figure 4 , an end of the rotating rod 61 away from the strip groove 611 is provided with a groove body extending inward, an extension piece 613 is slidably installed in the groove body, a third elastic piece is installed in the groove body, and the two ends of the third elastic piece respectively contact the extension piece 613 and the inner wall of the groove body; in this scheme, the extension piece 613 can be extended and retracted relative to the rotating rod 61, and can be completely placed in the safety mechanism 6 after extension and retraction. When the female head 2 is separated from the male head 1, the arc groove 211 will gradually squeeze the extension piece 613 to move into the groove body to avoid hindering the female head 2 from separating from the male head 1.

[0024] In a specific implementation manner, refer to Figure 5 , the two sides of the connecting plate 11 are rotatably installed with a clamping member 8, the clamping member 8 is provided with an arc guide rail 81, and the two sides of the female head 2 are provided with a first rod body 212 matching the arc guide rail 81. After the clamping member 8 is rotated, the distance between the first rod body 212 and the rotating axis of the clamping member 8 can be changed; in this scheme, when the male head 1 and the female head 2 are docked, the first rod body 212 on the side of the female head 2 will be located at the starting end of the arc guide rail 81, and then the clamping member 8 is rotated, and the radius of the distance from the starting end to the end of the arc guide rail 81 to the rotating axis of the clamping member 8 gradually decreases. Therefore, during the rotation of the clamping member 8, the female head 2 can be prompted to dock with the male head 1, and vice versa.

[0025] In a further embodiment, reference is made to Figure 5 , Figure 6 The clamping member 8 is connected to a second rod body 214, and a limiting hook 213 is arranged above the female head 2. The second rod body 214 is engaged with the limiting hook 213 to limit rotation. In this solution, after the clamping member 8 rotates, its second rod body 214 is located in the limiting hook 213, which can prevent the clamping member 8 from rotating, thereby limiting the separation of the female head 2 and the male head 1.

[0026] In a specific implementation manner, refer to Figure 7The first conductive component includes a terminal 41 and a metal column 42, the metal column 42 penetrates the sub-head 3 and is connected, the terminal 41 is connected to the connecting plate 11, the metal column 42 is slidably connected to the terminal 41, and the metal column 42 can contact and conduct electricity with the second conductive component 5; in this solution, the metal column 42 is installed in the sub-head 3, and its terminal 41 is installed in the male head 1, and its terminal 41 is a tube body, and its metal column 42 can slide relative to the terminal 41 to achieve the effect of extension or shortening, thereby coping with the sliding length of the sub-head 3.

[0027] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical scheme and inventive concept of the present invention within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
