[0081] The present invention is further described below by way of examples, but the present invention is not limited to the scope of the examples.

[0082] like Figures 1 to 5, which is a schematic diagram of the structure of the double-ended high-voltage plug-in device of the present invention, the double-ended high-voltage plug-in device comprises two sockets 200 and a double-ended high-voltage plug 100, the position of the sockets 200 corresponds to the position of the terminals 3, the sockets 200 are provided with jacks 20, the two terminals 3 are inserted into the corresponding jacks 20, and are closely matched with the jacks 20, so that the terminals 3 and the jacks 20 form a reliable electrical connection. Among them, the specific structure of the double-ended high-voltage plug 100 is as follows.

[0083] like Figures 1 to 14 As shown, the present invention provides a double-head high-voltage connector 100, which includes a shell body 1, a slide cover 2 and two terminals 3. The slide cover 2 is mounted on the shell body 1 and can slide relative to the shell body 1. The shell body 1 is provided with two terminal insertion ports 11. The two terminals 3 are respectively inserted into the two terminal insertion ports 11. The ends of the two terminals 3 located in the shell body 1 are floatingly connected. Among them, in a preferred solution, the sliding direction of the slide cover 2 relative to the shell body 1 is set to be perpendicular to the connection line of the two terminals 3.

[0084] Since the relative position between the two terminals 3 is adjustable, and the positions of the housing body 1 and the sliding cover 2 are adjustable, when the distance between the two sockets 200 is different from the original design value, the double-headed high-voltage connector 100 can still be inserted into the sockets 200. The double-headed high-voltage connector 100 has a wide range of applications and can adapt to small changes in the position of the socket 200; at the same time, it can still maintain a stable electrical connection under movement and shaking.

[0085] The sliding cover 2 can slide on the housing body 1. The specific structure is as follows: Figure 3 to Figure 4 , Fig. 9 , Fig.14 As shown. The inner wall of the housing body 1 is provided with a slide groove 12, the extension direction of the slide groove 12 is the same as the sliding direction of the slide cover 2, and the slide cover 2 is provided with a flange 21 inserted into the slide groove 12, and the flange 21 slides in the slide groove 12. The flange 21 slides in the slide groove 12, so that the slide cover 2 slides on the housing body 1, thereby driving the movement of the terminal 3.

[0086] A specific structure of the sliding cover 2 is as follows Fig. 9 As shown, the sliding cover 2 includes a sliding piece 23 and an abutting piece 24 vertically connected to the sliding piece 23; a flange 21 is provided on the edge of the sliding piece 23, and a sliding groove 12 is provided on the inner wall of the shell body 1. The extension direction of the sliding groove 12 is the same as the sliding direction of the sliding cover 2. The flange 21 slides in the sliding groove 12, and the shell body 1 has an opening 18 for the abutting piece 24 to enter the interior of the shell body 1.

[0087] The inner surface of the contact piece 24 contacts the sliding cover contact surface 37 of the terminal 3. The contact piece 24 is perpendicular to the sliding piece 23, and the sliding cover 2 forms an L-shaped plate structure. The sliding cover 2 can be easily installed on the housing body 1, and the overall structure of the plug connector is relatively compact. At the same time, at least one protruding anti-skid convex strip 22 is provided on the outer surface of the contact piece 24. The position of the anti-skid convex strip 22 is exactly the position where the operator contacts the sliding cover 2 when pushing the sliding cover 2, which facilitates the operator to push the sliding cover 2.

[0088] In order to ensure that the operator can smoothly push the slide cover 2, the outer surface of the slide cover 2 is provided with at least one protruding anti-skid convex strip 22. When the operator pushes the slide cover 2, the anti-skid convex strip 22 increases the friction between the slide cover 2 and the hand, making it easier for the operator to push the slide cover 2.

[0089] like Figures 2 to 5 , Figure 8 As shown, the ends of the two terminals 3 located in the housing body 1 are connected by a connecting terminal 6. The two terminals 3 are directly connected by the connecting terminal 6, which shortens the distance between the two terminals 3, so that the double-headed high-voltage plug 100 can be applied to the socket 200 with a smaller spacing.

[0090] The two terminals 3 are respectively provided with a fixed connection hole 32 and a sliding connection hole 33. One end of the connection terminal 6 is fixedly connected to the fixed connection hole 32 of one of the terminals 3, and the other end of the connection terminal 6 is floatingly installed in the sliding connection hole 33 of the other terminal 3 and maintains electrical connection. The other end of the connection terminal 6 can slide in the sliding connection hole 33, so that the relative position between the two terminals 3 can be appropriately adjusted according to the positions of the two sockets 200.

[0091] Specifically, at least one connecting conductive groove 61 is provided at one end of the connecting terminal 6 located in the sliding connecting hole 33, and a connecting conductive spring 7 is installed in the connecting conductive groove 61, and the connecting conductive spring 7 is in close contact with the inner circumference of the sliding connecting hole 33. The connecting conductive spring 7 partially protrudes out of the circumference of the connecting terminal 6 and presses on the inner circumference of the sliding connecting hole 33, so that the connecting terminal 6 can maintain good electrical connection while moving relatively, so that the relative position between the two terminals 3 can be appropriately adjusted.

[0092] like Figure 5 , Figures 10 to 14 As shown, the inner surface of the housing body 1 is provided with two pairs of guide bars 13, the head of each terminal 3 is located between the pair of guide bars 13, and the extending direction of the guide bars 13 is the same as the sliding direction of the slide cover 2. The pair of guide bars 13 are respectively located above and below the head of the terminal 3 ( Figure 8 As shown), the upward and downward movement of the terminal 3 is restricted, but the movement of the terminal 3 along the sliding direction of the sliding cover 2 is not restricted.

[0093] like Figures 10 to 14As shown, the housing body 1 is composed of two shell parts 14, and the two terminal insertion ports 11 are respectively located on the two shell parts 14. Specifically, a plurality of pairs of buckles 15 and slots 16 are provided at the connection of the two shell parts 14, and the two shell parts 14 are connected by a plurality of pairs of buckles 15 and slots 16 that engage with each other. Dividing the housing body 1 into two shell parts 14 facilitates the assembly of the double-headed high-voltage connector 100. At the same time, the buckle 15 can be appropriately moved in the slot 16, and the relative positions of the two shell parts 14 can be appropriately adjusted according to actual needs, thereby expanding the application range of the double-headed high-voltage connector 100.

[0094] like Figures 2 to 8 As shown, the terminal 3 is provided with at least one terminal conductive groove 34 along the circumferential direction, and a terminal conductive spring 8 is installed in the terminal conductive groove 34, and the terminal conductive spring 8 protrudes out of the circumferential surface of the terminal 3. When the terminal 3 is inserted into the insertion hole 20 of the socket 200, the terminal conductive spring 8 is in close contact with the inner circumferential surface of the insertion hole 20, so that the terminal 3 is electrically connected to the socket 200, and the relative position of the terminal 3 and the socket 200 can be appropriately adjusted to adapt to the position error of the socket 200.

[0095] like Figures 2 to 8 As shown, the terminal 3 is provided with at least one terminal sealing groove 35 along the circumferential direction, and a terminal sealing strip 9 is installed in the terminal sealing groove 35, and the terminal sealing strip 9 protrudes out of the circumferential surface of the terminal 3. When the terminal 3 is inserted into the insertion hole 20 of the socket 200, the terminal sealing strip 9 is in close contact with the inner circumferential surface of the insertion hole 20, so that the terminal 3 and the socket 200 are kept sealed.

[0096] like Figures 2 to 4 As shown, an annular space 4 for the socket 200 to be inserted is formed between the terminal insertion port 11 and the terminal 3, and an elastic member is provided between the terminal 3 and the shell body 1. The force direction of the elastic member is parallel to the sliding direction of the sliding cover 2 and perpendicular to the connection axis of the two terminals 3.

[0097] When the double-ended high-voltage connector 100 is not connected to the socket 200, an elastic member is provided between the housing body 1 and the terminal 3, so that the terminal 3 is pressed against one side of the terminal insertion opening 11, and the slide cover 2 is at the outermost side. If no external force is applied to the slide cover 2, the socket 200 cannot be inserted into the double-ended high-voltage connector 100.

[0098] When the double-head high-voltage connector 100 needs to be connected to the socket 200, an external force is applied to the slide cover 2 to slide the slide cover 2 toward the inside of the chamber relative to the housing body 1, thereby driving the terminal 3 to move together with the slide cover 2, so that the terminal 3 moves to the middle of the terminal insertion port 11. The terminal 3 is inserted into the socket 200, and the socket 200 is inserted into the annular space 4 formed between the terminal insertion port 11 and the terminal 3. After the socket 200 is inserted, the external force of the slide cover 2 is removed, and under the action of the elastic member, the socket 200 contacts the terminal insertion port 11, and the socket 200 is locked with the housing body 1.

[0099] When the double-head high-voltage connector 100 needs to be separated from the socket 200, an external force is applied to the slide cover 2 to make the slide cover 2 relatively retracted, so that the terminal 3 and the socket 200 move to the middle of the terminal insertion port 11, and the socket 200 is unlocked from the housing body 1, so that the terminal 3 can be separated from the socket 200.

[0100] The double-ended high-voltage connector 100 controls the position of the terminal 3 through the sliding cover 2 and the elastic member, has a compact structure, a small size, and is easy to install. It is particularly suitable for a plugging position where the distance between two sockets 200 is small or the plugging space is small.

[0101] like Figures 2 to 4 As shown, the terminal 3 has a relative elastic member installation surface 36 and a sliding cover contact surface 37, the sliding cover contact surface 37 contacts the sliding cover 2, the elastic member installation surface 36 contacts one end of the elastic member, and the other end of the elastic member contacts the inner wall of the housing body 1. Through the above-mentioned structural arrangement, the structure of the double-head high-voltage connector 100 is more compact and can be designed to be smaller in size.

[0102] like Figures 2 to 4 As shown, the elastic member is two compression springs 5, the axis of the compression spring 5 is the same as the sliding direction of the slide cover 2 and is perpendicular to the connection direction of the two terminals 3, the two compression springs 5 ​​are in contact with the two terminals 3 respectively, and the two compression springs 5 ​​are located on the same side of the two terminals 3. The compression springs 5 ​​are designed on the same side of the two terminals 3, and the other side uses the slide cover 2 to directly contact the slide cover contact surface 37 of the terminal 3. This structure is more compact, the plug can also be designed to be smaller in size, and the distance between the two terminals 3 can also be designed to be smaller. This plug is particularly suitable for a plug position where the distance between the two sockets 200 is small or the plug space is small.

[0103] The installation method between the compression spring 5, the housing body 1 and the terminal 3 is as follows: Figures 2 to 4 The inner surface of the housing body 1 is provided with a housing mounting column 17, the terminal 3 is provided with a terminal mounting column 31, and the two ends of the compression spring 5 are respectively mounted on the housing mounting column 17 and the terminal mounting column 31.

[0104] like Figures 1 to 5 As shown, the double-ended high-voltage connector 100 is connected with the socket 200 to form a double-ended high-voltage connector. The double-ended high-voltage connector comprises two sockets 200 and the double-ended high-voltage connector 100. The positions of the sockets 200 correspond to the positions of the terminals 3. The sockets 200 are provided with jacks 20. The two terminals 3 are inserted into the corresponding jacks 20.

[0105] like Figures 2 to 5As shown, the terminal 3 is provided with at least one terminal conductive groove 34 along the circumferential direction, and a terminal conductive spring 8 is installed in the terminal conductive groove 34, and the terminal conductive spring 8 is in close contact with the inner circumferential surface of the socket 20. The terminal conductive spring 8 electrically connects the terminal 3 to the socket 200, and can appropriately adjust the relative position of the terminal 3 and the socket 200 to adapt to the position error of the socket 200.

[0106] like Figures 2 to 5 As shown, the terminal 3 is provided with at least one terminal sealing groove 35 along the circumferential direction, and a terminal sealing strip 9 is installed in the terminal sealing groove 35, and the terminal sealing strip 9 is in close contact with the inner circumferential surface of the jack 20. When the terminal 3 is inserted into the jack 20 of the socket 200, the terminal sealing strip 9 is in contact with the inner circumferential surface of the jack 20, so that the terminal 3 and the socket 200 are kept sealed.

[0107] like Figures 2 to 5 As shown, the outer peripheral surface of the socket 200 is provided with an annular groove 30, and the edge of the terminal insertion opening 11 is inserted into the annular groove 30. After the terminal 3 is inserted into the socket 200, the external force of the slide cover 2 is removed, and under the action of the elastic member, the terminal 3 moves to one side of the terminal insertion opening 11, so that the edge of the terminal insertion opening 11 is inserted into the annular groove 30, and the socket 200 is locked with the housing body 1.
