[0035] In the embodiment of the present utility model, Figures 1 to 7 As shown, the conversion plug 100 proposed by the utility model includes:

[0036] A track 10, wherein the track 10 is provided with a slot 11, and a conductive member 12 is installed on the inner wall of the slot 11; and

[0037] The plug part 20 is plugged into the slot 11. The plug part 20 includes a main body 21 and a docking part 22. The docking part 22 is arranged on the main body 21. A conductive elastic member 23 is installed on the docking part 22. The conductive elastic member 23 is protruded outwardly relative to the docking part 22. The docking part 22 is plugged into the slot 11, and the conductive elastic member 23 is in conflict with the conductive member 12.

[0038] The track 10 may be provided with a plurality of slots 11 so that one of the slots 11 can be selected for plugging in. Specifically, the four sides of the track 10 are provided with slots 11, and the conversion plug 100 can be inserted into one of the slots 11 to achieve conduction.

[0039] In one embodiment, the conductive member 12 is a conductive copper strip. A conductive copper strip is installed in each of the slots 11. Specifically, the two opposite inner walls of the slot 11 are both installed with a conductive copper strip. The docking portion 22 of the plug portion 20 is correspondingly provided with two conductive elastic members 23. When the docking portion 22 is inserted into the slot 11, the two conductive elastic members 23 on the docking portion 22 respectively contact with the two conductive copper strips on the inner wall of the slot 11, thereby achieving conduction. The conductive member 12 can be adhered to the inner wall of the slot 11 by gluing, or can be snapped into the inner wall of the slot 11 by snapping.

[0040] The technical solution of the utility model is to set a track 10, the track 10 is provided with a slot 11, the inner wall of the slot 11 is installed with a conductive member 12, the plug part 20 is inserted into the slot 11, the plug part 20 includes a main body 21 and a docking part 22, the docking part 22 is arranged on the main body 21, the docking part 22 is installed with a conductive elastic member 23, the conductive elastic member 23 is arranged to protrude outward relative to the docking part 22, the docking part 22 is inserted into the slot 11, the conductive elastic member 23 and the conductive member 12 are in conflict, and then conduction is achieved. Since the conductive elastic member 23 is elastic, even if there is a certain tolerance in the manufacturing of the slot 11 in the track 10, the conductive elastic member 23 in the slot 11 can be compressed and deformed, and in conflict with the conductive member 12 on the inner wall of the slot 11, so as to achieve conduction, the adaptability of the conversion plug 100 is improved, and the conversion plug 100 is prevented from failing to conduct due to tolerance problems.

[0041] In order to prevent the conductive elastic member 23 from being separated from the docking portion 22 , a fixing cavity 220 is defined in the docking portion 22 , and the conductive elastic member 23 is installed in the fixing cavity 220 . Part of the conductive elastic member 23 protrudes from the docking portion 22 to contact the conductive member 12 .

[0042] The two opposite sides of the docking portion 22 are provided with through holes 2210, and the through holes 2210 are connected to the fixing cavity 220. In one embodiment, the conductive elastic member 23 is fixed to the fixing cavity 220, and a part of the conductive elastic member 23 extends out of the through hole 2210 so as to contact with the conductive member 12, thereby achieving conduction.

[0043] Since the conductive elastic member 23 is fixed in the fixing cavity 220 , the conductive elastic member 23 is not easily separated from the docking portion 22 .

[0044] Specifically, the conductive elastic member 23 includes a connecting portion 231 and a spring-loaded portion 232 . The connecting portion 231 is disposed in the fixing cavity 220 , and the spring-loaded portion 232 is exposed from the docking portion 22 . The spring-loaded portion 232 contacts the conductive member 12 .

[0045] In one embodiment, the connecting portion 231 is fixed in the fixing cavity 220 to ensure that the conductive elastic member 23 is fixed to the docking portion 22. The compression spring portion 232 is exposed from the docking portion 22 so that the compression spring portion 232 contacts the conductive member 12 to achieve conduction.

[0046] Among them, Figures 1 to 7 As shown, the docking portion 22 includes a limiting portion 221, a locking portion 222 and a positioning portion 223, the locking portion 222 is located between the limiting portion 221 and the positioning portion 223, the limiting portion 221 is protruded relative to the locking portion 222, the positioning portion 223 is connected to the main body 21, the limiting portion 221 and the locking portion 222 are inserted into the slot 11, and the compression spring portion 232 is exposed from the limiting portion 221.

[0047] In one embodiment, the spring-pressing portion 232 is exposed from the limiting portion 221, and the limiting portion 221 is inserted into the slot 11. The spring-pressing portion 232 is squeezed and compressed by the inner wall of the slot 11 in the slot 11, and the spring-pressing portion 232 can still contact the conductive member 12 on the inner wall of the slot 11. In one embodiment, the spring-pressing portion 232 has a C-shaped shape.

[0048] In order to prevent the plug part 20 from falling out of the slot 11, the slot 11 includes a limiting slot 110 and a locking slot 111, and the conductive member 12 is installed on both inner side walls of the limiting slot 110. The limiting part 221 is inserted into the slot 11, and the locking part 222 is inserted into the locking slot 111.

The protruding blocks 2211 protrude relative to the locking portion 222, so that the conductive elastic member 23 can contact the conductive member 12 in the slot 11.

[0050] In order to limit the docking portion 22 to the track 10, the slot 11 is provided with two card plates 112, and a card slot 111 is defined between the two card plates 112. The card portion 222 of the plug portion 20 is inserted into the card slot 111, and the two card plates 112 prevent the limiting portion 221 of the docking portion 22 from being separated from the slot 11, so as to ensure that the conductive elastic member 23 on the limiting portion 221 contacts the conductive member 12 and does not separate from the slot 11.

[0051] like Figures 1 to 5 As shown, in order to facilitate the insertion of the plug portion 20 into the slot 11 of the rail 10 , the thickness of the docking portion 22 is smaller than the diameter of the locking groove 111 .

[0052] It can be understood that, since the thickness of the docking part 22 is smaller than the diameter of the clamping groove 111, the side of the docking part 22 with the conductive elastic member 23 is mounted upward, and the limiting portion 221 of the docking part 22 can extend laterally into the clamping groove 111 between the two clamping plates 112. Specifically, when the plug part 20 needs to be installed on the track 10: first, the side of the docking part 22 with the conductive elastic member 23 is mounted upward, and then the limiting portion 221 of the docking part 22 passes through the clamping groove 111, so that the limiting portion 221 enters the limiting groove 110; then, the docking part 22 is rotated 90 degrees until the conductive elastic member 23 on the limiting portion 221 contacts the conductive member 12 and stops rotating, and the conductive elastic member 23 and the conductive member 12 are squeezed against each other, thereby limiting the docking part 22, and the docking part 22 is limitedly installed in the slot 11. The slot 11 in the track 10 has a certain tolerance in manufacturing, and the conductive elastic member 23 can still be compressed and deformed by the conductive member 12 in the slot 11, and then can be in contact with the conductive member 12 to improve the adaptability of the conversion plug 100 of the utility model.

[0053] like Figures 5 to 7 As shown, for ease of assembly, the docking portion 22 includes a first docking portion 224 and a second docking portion 225 , and the first docking portion 224 is connected to the second docking portion 225 to enclose a fixing cavity 220 .

[0054] In one embodiment, the first docking portion 224 is engaged with the second docking portion 225. The conductive elastic member 23 is installed between the first docking portion 224 and the second docking portion 225. The connecting portion 231 of the conductive elastic member 23 is limitedly installed in the fixing cavity 220, and the spring-pressing portion 232 of the conductive elastic member 23 is bent relative to the connecting member and exposed outside the first docking portion 224 and the second docking portion 225 to contact the conductive member 12.

[0055] Among them, Figures 5 to 7 As shown, the main body 21 includes a base 210, a circuit board 211 and a shell 212. The shell 212 covers the base 210 and encloses a receiving cavity 214. The circuit board 211 is arranged in the receiving cavity 214. The conductive elastic member 23 is electrically connected to the circuit board 211.

[0056] In one embodiment, the base 210 can be used to connect with the docking portion 22 to limit the docking portion 22 to be installed on the main body 21. The base 210 is clamped with the housing 212, and the circuit board 211 is installed in the accommodating cavity 214. The conductive elastic member 23 is electrically connected to the circuit board 211, and the docking portion 22 is inserted into the slot 11. The conductive elastic member 23 contacts the conductive member 12, and the conductive member 12 is energized. The conversion plug 100 is turned on through the conductive elastic member 23.

[0057] In order to limit the docking portion 22 to be located on the main body 21 , the base 210 is provided with a positioning groove 213 , the positioning portion 223 is installed in the positioning groove 213 , and the docking portion 22 is snap-connected with the base 210 .

[0058] In one embodiment, the positioning portion 223 is engaged in the positioning groove 213, so that the docking portion 22 is engaged with the main body 21, and the docking portion 22 is not easily separated from the main body 21. The base 210 may be cylindrical in shape.

[0059] like Figure 7 As shown, in order to facilitate the installation of the conductive elastic member 23 on the docking portion 22 , the conductive elastic member 23 includes two elastic members 230 , and the two elastic members 230 are disposed opposite to each other in the fixing cavity 220 .

[0060] In one embodiment, the two elastic members 230 are relatively arranged in the fixed cavity 220, and the two elastic members 230 each include a connecting portion 231 and a spring-loaded portion 232.
