[0004] To solve the above problems, the present invention adopts the following technical solution: a protective door to prevent the insertion of sharp metal, comprising a main body, wherein an inclined driving part corresponding to a first insertion hole is formed on the main body, and a plurality of recesses are arranged on the inclined driving part, the recesses being used to prevent sharp metal from forcing the main body to slide.
[0005] In some possible embodiments, the recesses cover the surface of the tilting drive portion, and the maximum size of the recesses is smaller than the minimum size of the plug.
[0006] In some possible embodiments, the cross-section of the recess includes a first connecting segment and a second connecting segment connected at one end, the first connecting segment being located at the lower end of the second connecting segment, and the angle between the extension line of the first connecting segment and the tilting drive portion being greater than 90° and less than 135°.
[0007] In some possible embodiments, the other ends of the first connecting segment and the second connecting segment both extend into the depth of the body and are connected in an arc.
[0008] This utility model also provides a safety protection component, which includes a first protective plate, two protective doors as described in the above embodiment are disposed on the first protective plate, the tilting directions of the tilting drive parts on the two protective doors are consistent, and the two protective doors move synchronously with the first protective plate.
[0009] In some possible embodiments, a second protective plate is also included, which has two inclined perforations. The two protective doors are respectively disposed on one side of the two perforations. The length of the perforations is greater than the length of the plug. An elastic element is also provided between the first protective plate and the second protective plate.
[0010] This utility model also provides a plug-in device panel, which includes a cover and a safety protection component as described in the above embodiment. The cover has a first plug hole, and the safety protection component is slidably and repositionably disposed on the inner side of the cover. The protective door is used to close the first plug hole.
[0011] In some possible embodiments, the faceplate is provided with a guide groove, through which one side of the body passes, so that the body can slide linearly back and forth relative to the faceplate.
[0012] In some possible embodiments, a protective cover is also provided on the inner side of the face cover, and a protective compartment is formed between the protective cover and the face cover. The safety protection component is disposed in the protective compartment, and a second socket corresponding to the first socket is provided on the protective cover.
[0013] This utility model also provides a plugging / unplugging device, which includes a plugging / unplugging device panel as described in the above embodiment, and further includes: Base; A plurality of inserts are fixedly installed in the base in a mutually isolated manner, and each insert is provided with a connection terminal; The plug-in / plug-out device panel is mounted on the base, and the first plug hole on the plug-in / plug-out device panel corresponds one-to-one with the connection terminal inside the plug compartment.
[0014] Compared with the prior art, the beneficial effects of this utility model are as follows: The protective door of this utility model has an inclined driving part on the main body corresponding to the first insertion hole. Several recesses are arranged on the inclined driving part. When the plug is inserted, the inclined driving part can force the protective door to slide to make way for the plug, so that the plug can be inserted smoothly. When a sharp metal is inserted, its tip is blocked in the recess and cannot be inserted further, and the protective door is forced to slide. This avoids the safety risk of the sharp metal moving along the inclined driving part and forcing the protective door to make way for the sharp metal, which would lead to the sharp metal being inserted and coming into contact with the connection terminal.

Detailed Implementation
[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0019] Reference Figure 1 The aforementioned protective door for preventing the insertion of sharp metal includes a main body 21. The main body 21 has an inclined driving part 23 corresponding to a first socket 31. The inclined driving part 23 is provided with a plurality of recesses 24. When the plug is correctly inserted, the plug will press against the inclined driving part 23 and force the protective door to slide, so that the plug can be smoothly inserted to draw power. When sharp metal is inserted into the first socket 31, its end will be placed in the recesses 24 and blocked by the recesses 24, so that the sharp metal cannot force the protective door to slide and continue to be inserted to draw power, thus avoiding misinsertion and ensuring safety.
[0020] In some possible embodiments, the maximum size of the recess 24 is smaller than the minimum size of the plug to ensure that the plug is not blocked by the recess 24 when inserted, while a sharp or hard object will be blocked by the recess 24 when inserted.
[0021] In some possible embodiments, refer to Figure 3 As shown, the cross-section of the recess 24 includes a first connecting segment and a second connecting segment connected at one end. The first connecting segment is located at the lower end of the second connecting segment. The angle between the first connecting segment and the tilting drive part 23 is greater than 90° and less than 135°. When the sharp metal is inserted, it will be inserted along the second connecting segment until its end presses against the first connecting segment. At this time, the horizontal component of the force exerted by the sharp metal on the first connecting segment is insufficient to push the protective door to slide, thus ensuring that the sharp metal cannot be inserted into the insertion compartment 11 and contact the connecting terminal 12.
[0022] In some possible embodiments, refer to Figure 3 As shown, the other ends of the first connecting segment and the second connecting segment extend into the depth of the main body 21 and are connected in an arc shape, that is, the bottom of the recess 24 is arc-shaped, which avoids the risk that the end of the sharp metal will break under force and get stuck in the gap of the protective chamber 20.
[0023] This application also provides a security protection component, as shown in the reference. Figure 1 As shown, it includes a first protective plate 25 and protective doors as described in the above embodiment. There are two protective doors, which are respectively located on both sides of the first protective plate 25. The tilting drive parts 23 on the two protective doors are tilted in the same direction. When the two prongs on the plug are inserted, the two protective doors are pressed and the horizontal component of the force they receive is in the same direction. The two protective doors move synchronously and in the same direction with the first protective plate 25 to make way for the plug, ensuring that the two prongs on the plug are inserted simultaneously to draw power. This embodiment has a structure with two protective doors on the first protective plate 25 to protect the two-phase plugging and unplugging device in a coordinated manner. This can avoid the problem of electric shock caused by the insertion of a single metal piece or metal rod. That is, this structure can realize the function of preventing incorrect insertion and misinsertion.
[0024] In some possible embodiments, the safety protection component further includes a second protective plate 26, which has two inclined through holes 27, as shown in the figure. Figure 1As shown, the two holes 27 correspond to the neutral and live wires of the three-prong plug. Each of the two holes 27 has a protective door on one side, and the length of the hole 27 is greater than the length of the plug. When the three-prong plug is inserted, it will press against and force the second protective plate 26 to slide so that the two protective doors can give way to the three-prong plug, ensuring that the three-prong plug can be smoothly inserted into the plug compartment 11. The length of the hole 27 should be appropriately long to ensure that the side wall of the hole 27 will not interfere with the plug during the sliding of the second protective plate 26. Furthermore, an elastic element 28 is provided between the first protective plate 25 and the second protective plate 26. The elastic element 28 can be a conventional compression spring. Under normal conditions, the elastic element 28 is in a compressed state so that the first protective plate 25 always tends to move to the left, while the second protective plate 26 always tends to move to the right. When the two-prong plug is inserted, it can force the first protective plate 25 to slide to the right, and the elastic element 28 is compressed. At this time, the second protective plate 26 is fixed. When the three-prong plug is inserted, the second protective plate 26 slides to the left while the first protective plate 25 is fixed.
[0025] This utility model also provides a plug-in / plug-out device panel, see reference. Figures 1 to 3 As shown, it includes a faceplate 30 and a faceplate 30 as described in the above embodiment. The faceplate 30 has a first insertion hole 31. A safety protection component is slidably and repositionably disposed inside the faceplate 30. Under normal conditions, the safety protection component can close the first insertion hole 31. When the plug is correctly inserted, the plug can force the safety protection component to slide relative to the faceplate 30, so that the protective door opens, allowing the plug to be smoothly inserted and draw power. When a sharp metal is inserted, it will be blocked by the recess 24, preventing it from being inserted further and forcing the protective door to slide, thereby avoiding the problem of electric shock due to accidental insertion.
[0026] In some possible embodiments, refer to Figure 1 As shown, a guide groove 29 is provided on the cover 30, and one side of the main body 21 passes through the guide groove 29. Specifically, the sides of the first protective plate 25 and the second protective plate 26 are formed with guide strips extending along their movement direction. The guide strips are inserted into the guide groove 29 so that when the first protective plate 25 and the second protective plate 26 are driven by force, they can slide back and forth linearly relative to the cover 30.
[0027] In some possible embodiments, refer to Figure 2 and Figure 3 As shown, a protective cover 13 is also provided on the inner side of the face cover 30. A protective compartment 20 is formed between the protective cover 13 and the face cover 30. The safety protection component is set in the protective compartment 20. The protective cover 13 is provided with a second socket 22 corresponding to the first socket 31. When the plug is correctly inserted from the first socket 31, it will force the protective door to slide in the protective compartment 20 and give way to the plug, so that the plug can be inserted into the second socket 22 and correctly draw power.
[0028] This utility model also provides a plugging / unplugging device, see reference. Figures 1 to 4 As shown, it includes a base 10, a plug-in device panel as described in the above embodiment, and a plurality of plug-in compartments 11. The base 10 has an open mounting cavity at one end. The plurality of plug-in compartments 11 are disposed within the mounting cavity, isolated from each other. The plug-in device panel is fitted onto the open end of the mounting cavity, enclosing all the plug-in compartments 11 within the mounting cavity. A connection terminal 12 is provided within each plug-in compartment 11. The connection terminal 12 is connected to an external power source via a wire. The first socket 31 on the cover 30 and the second socket 22 on the protective cover 13 correspond one-to-one with each of the plug-in compartments 11, allowing the plug to be inserted from top to bottom through the first socket 31 and the second socket 22, making contact with the connection terminal 12 within the plug-in compartment 11 to draw power. It should be understood that the remaining space within the mounting cavity can be used to house components such as circuit boards and copper sheets, enabling the connection terminals 12 to conduct electricity when connected to an external power source.
