The bottom cover 2 is arranged below the surface cover 1, and the main body 3 is arranged below the bottom cover 2.

[0044] See also Figures 2 to 8The cover 1 includes an upper cover plate 11 and a rotating cover 13 arranged on the upper cover plate 11. A rotating groove 12 is provided on the upper end surface of the upper cover plate 11. A second plug hole 14 is provided on the rotating groove 12. The rotating cover 13 is arranged in the rotating groove 12, and the rotating cover 13 can rotate in the rotating groove 12 under the action of an external force. A first plug hole 19 for plugging a plug is provided on the rotating cover 13, and a positioning column 16 is provided in the middle of the first plug hole 19 on the rotating cover 13. A first tension spring shaft 18 is provided on one side of the positioning column 16, and a first spring 15 and a closing plate 17 are sleeved on the positioning column 16. When the first spring 15 is in the default state, the closing plate 17 closes the opening on the rotating cover 13. When After the plug on the external plug is inserted into the socket hole on the rotating cover 13, the downward pressing closing plate 17 is squeezed. At this time, the first spring 15 is compressed, and the closing plate 17 is separated from the rotating cover 13. After the rotating cover 13 is rotated to a certain angle, the socket hole on the rotating cover is aligned with the socket holes on the upper cover 11 and the bottom cover 2. The plug can continue to be inserted and powered on. Therefore, the first spring 15, the positioning column 16 and the closing plate 17 cooperate to achieve the anti-accidental touch function, wherein the closing plate 17 is located above the first spring 15. A closing block 110 adapted to the first socket hole 19 is provided on the closing plate 17. The closing block 110 can open or close the first socket hole 19 under the action of the first spring 15. Figures 3 and 4 It can be seen that a tension spring groove 111 is provided on one side of the second plug-in hole 14 on the rotating groove 12, and a tension spring 112 is provided in the tension spring groove 111. One end of the tension spring 112 is connected to the first tension spring shaft 18, and the other end is connected to the second tension spring shaft 113 in the tension spring groove 111. A limiting flange 114 is provided on the end of the positioning column 16 away from the rotating cover 13, and the limiting flange 114 is limitedly connected to the first spring 15.

[0045] See also Figure 9 The bottom cover 2 is detachably connected to the surface cover 1 . The bottom cover 2 includes a lower cover plate 21 . A third plug hole 22 is formed on the lower cover plate 21 .

[0046] See also Figure 10 The lower cover 21 is provided with an outwardly extending extension plate 23, on which a plurality of snap-in grooves 24 are provided. A limiting portion 26 is provided in the third plug-in hole 22 on the lower cover 21. The main body 3 includes a shell 31, on which a card block 32 adapted to the snap-in groove 24 is provided, and the card block 32 is detachably connected to the snap-in groove 24.

[0047] See also Figure 11 The housing 31 is provided with a plug-in slot 33 , in which a retaining spring 34 is provided. The plug-in slot 33 is located directly below the second plug-in hole 14 .

[0048] See also Figure 12The housing 31 is also provided with a spring holding portion 35 of a limited retaining spring 34. The retaining spring 34 includes a tailstock 341, a retracted portion 342 provided on the tailstock 341, and a retaining spring guide portion 343 provided on the retracted portion 342. The tailstock 341 is U-shaped, wherein the tailstock 341 is located at the bottom of the plug-in slot 33, the retracted portion 342 is limitedly connected to the spring holding portion 35, and the two end legs 344 on the retaining spring guide portion 343 are located in the limiting slot 27. By fixing the tailstock 341 to the plug-in slot 33, the retracted portion 342 is pushed inwardly under the action of the second spring 352, so that the inner surface of the retaining spring guide portion 343 and the inner protrusion 262 of the limiting portion 26 are in contact with each other. After the insert is inserted, since the thickness of the insert is greater than the distance of the retracted portion 342, the insert will push the retaining spring 34 outward. The retaining spring 34 is tightly attached to the insert under the action of the outward push of the insert and the inward push of the spring supporting portion 35. Since the spring has a long life, the retaining spring 34 will still be in contact with the shrapnel after long-term use, thereby extending its life.

[0049] See also Figure 13 The spring supporting portion 35 includes a spring groove 351 opened on the main body 3, and a second spring 352 is arranged in the spring groove 351. The second spring 352 is sleeved on the guide column 353. The guide column 353 is integrally formed on the limit block 354, and an annular accommodating groove 355 for accommodating the second spring 352 is provided on the guide column 353. The limit block 354 on the guide column 353 is in contact and connected with the retracted portion 342 under the action of the second spring 352, so the limit block 354 plays a positioning role for the retaining spring 34.

[0050] Please refer again Figure 13 The end foot 344 of the retaining spring 34 is inserted into the limiting groove 27 of the limiting part 26. Under the action of the second spring 352, the inner surface of the retaining spring guide part 343 and the inner protrusion 262 of the limiting part 26 are attached together (when the insert is not inserted). The distance between the top of the retaining spring guide part 343 and the inner wall of the outer protrusion 261 is L1, and the value of L1 is between 0.1-5mm.

[0051] See also Figure 14 and Figure 15 A jack block groove 116 is also provided at the first grounding jack 141 of the face cover 1, and a jack block 131 is also provided on the inner side of the second grounding jack 191 of the first socket 19. The height of the hole block groove 116 is between 0.5 mm and 5 mm, the width of the jack block 131 is slightly smaller than the width of the jack block groove 116, and the height of the jack block 131 is slightly smaller than the height of the jack block groove 116.

[0052] It should be noted that, in the present invention, the socket body 3 can also be connected and fixed to the upper cover plate 11 by screws, and the body 31 can also be connected and fixed to the upper cover plate 11 by screws.

[0053] Embodiment two:

[0054] Please refer to Figures 16 and 17 The second embodiment of the present application provides: the structure of this embodiment is basically the same as that of the first embodiment, and the difference is that the present application cancels the spring holding part 35. When the end foot 344 of the snap spring 34 is inserted into the limiting slot 27 of the limiting part 26, the inner wall of the snap spring guide part 343 and the inner protruding part 262 of the limiting part 26 are attached together, the outer edge of the end foot 344 of the snap spring 34 and the inner wall of the outer protruding part 261 of the limiting part 26 are attached together, and the end foot 344 of the snap spring 34 is fixed. When the plug is inserted into the snap spring 34, because the distance L of the inwardly recessed part 342 of the snap spring 34 is smaller than the thickness of the plug, the plug will press the inwardly recessed part 342. Because the end foot 344 of the snap spring 34 is fixed and cannot move outwardly, the plug presses the inwardly recessed part 342 of the snap spring, so that the plug and the snap spring 34 are attached together. The other unexplained places of this embodiment are referred to the first embodiment, and will not be described here.

[0055] It is apparent for those skilled in the art that the present application is not limited to the details of the above-described exemplary embodiments, and can be realized in other concrete forms without departing from the spirit or essential characteristics of the present application. Therefore, the embodiments should be considered in all aspects as illustrative and not restrictive, and the scope of the present application is defined by the appended claims rather than the above description, and all changes falling within the meaning and range of the equivalent elements of the claims are intended to be embraced therein. Any reference signs in the claims should not be considered as limiting the claims involved.
