[0071] Exemplarily, continue to see Figure 3 Or Figure 4The two-insert protection door 12 can be rectangular, and the three-insert protection door 13 can be rectangular or trapezoidal.

[0072] Thus, the protection door structure provided in the embodiment of the utility model can be applied to the socket with the combined five holes, the overall installation compactness of the protection door is reduced, and the first elastic reset member 14 can avoid the E-pole bolt, the insertion of the E-pole bolt is facilitated, and the protection door structure can be applied to the socket with the combined five holes.

[0073] In some embodiments, referring to Figure 5 , Figure 6 and Figure 7 , wherein Figure 5 is a structure schematic view of a two-insert protection door and a three-insert protection door provided in the embodiment of the utility model, Figure 6 is another structure schematic view of a two-insert protection door and a three-insert protection door provided in the embodiment of the utility model, Figure 7 is still another structure schematic view of a two-insert protection door and a three-insert protection door provided in the embodiment of the utility model, the two-insert protection door 12 has a first surface 121 away from the support base 11, and the first surface 121 is provided with a first opening hole 122 allowing the insertion of the bolt; after the insertion of the bolt, the bolt can push the two-insert protection door 12 to move along with the insertion of the first opening hole 122.

[0074] Exemplarily, referring to Figure 5 , the number of the first opening holes 122 can be two, and the two first opening holes 122 are arranged side by side. Further, referring to Figure 3 , in the case that the two-insert protection door 12 is in a normal state, referring to the upper part of Figure 3 , the two first opening holes 122 and the three first through holes 1111 on the support base 11 are staggered; in the case that the two-insert protection door 12 is in a pressed state, referring to the lower part of Figure 3 , one first through hole 1111 on the support base 11 is exposed due to the movement of the two-insert protection door 12, and the other two first through holes 1111 are respectively communicated with the two first opening holes 122.

[0075] Exemplarily, referring to Figure 6 , the number of the first opening holes 122 can be one. Further, referring to Figure 4 , the size of the first opening hole 122 is relatively large; in the case that the two-insert protection door 12 is in a normal state, referring to the upper part of Figure 4 , the first opening hole 122 is relatively communicated with the E-pole through hole 11111 on the support base 11, and is staggered with the other two first through holes 1111; in the case that the two-insert protection door 12 is in a pressed state, referring to Figure 4The first through hole 1111 on the support base 11 is exposed due to the movement of the two-plug protection door 12, another first through hole 1111 is communicated with the first opening 122, and the E pole through hole 11111 is always communicated with the first opening 122.

[0076] For the arrangement of the first surface 121, there are two possible implementation manners in the embodiment of the utility model:

[0077] In one possible implementation manner, referring to Figure 5 or Figure 6 , the first surface 121 is a plane. In this way, as long as the panel or the cover of the socket with the jack is also designed as a plane, the jack of the socket and the two-plug protection door 12 can be tightly matched, and there will be no space such as a wedge-shaped gap between the two, realizing the pure flat effect of the appearance, which can not only prevent dust and other impurities from entering the interior of the socket, has good sealing property, but also can effectively prevent water splashing, and is beneficial to improving the appearance of the socket.

[0078] In another possible implementation manner, referring to Figure 7 , the first surface 121 is provided with a first guide groove 124, and the first guide groove 124 is arranged adjacent to the first opening 122 and is used for guiding the insertion of the plug pin into the first opening 122.

[0079] By arranging the first guide groove 124 on the first surface 121, the insertion of the plug pin into the first opening 122 is facilitated, thereby facilitating the pushing of the two-plug protection door 12.

[0080] In some embodiments, referring to Figures 5 to 7 , the three-plug protection door 13 has a second surface 131 away from the support base 11, and the second surface 131 is provided with a second opening 132 allowing the plug pin to be inserted, and after the plug pin is inserted, the plug pin can push the three-plug protection door 13 to move as the plug pin is inserted into the second opening 132.

[0081] Exemplarily, referring to Figure 5 or Figure 6 , the number of the second opening 132 can be one. Further, referring to Figure 3 or Figure 4 , when the three-plug protection door 13 is in a normal state, the second opening 132 is arranged staggered with a second through hole 1112 on the support base 11; when the three-plug protection door 13 is in a stressed state, one of the second through holes 1112 on the support base is exposed due to the movement of the three-plug protection door 13, and another first through hole 1111 is communicated with the second opening 132.

[0082] Similar to the arrangement of the first surface 121, the arrangement of the second surface 131 has the following two possible implementation manners in the embodiments of the utility model:

[0083] In a possible implementation manner, referring to Figure 5 or Figure 6 , the second surface 131 is a plane. In this way, as long as the panel or the cover of the socket with the socket is also designed as a plane, the socket and the three-plug protection door 13 can be tightly matched, and there will be no space such as a wedge-shaped gap between the two, realizing the pure flat effect of the appearance, which can not only prevent dust and other impurities from entering the interior of the socket, has good sealing property, but also can effectively prevent water splashing, and is beneficial to improving the appearance of the socket.

[0084] In another possible implementation manner, referring to Figure 7 , the second surface 131 is provided with a second guide groove 134, and the second guide groove 134 is arranged adjacent to the second opening 132 and is used for guiding the insertion of the plug pin into the second opening 132.

[0085] By arranging the second guide groove 134 on the second surface 131, the plug pin is guided to be inserted into the second opening 132, so that the three-plug protection door 13 is facilitated to be pushed.

[0086] In the embodiments of the utility model, the first elastic reset member 14 is arranged around the two-plug protection door 12. For the specific arrangement of the first elastic reset member 14, the following two possible implementation manners can be used:

[0087] In a possible implementation manner, referring to Figure 1 , the first elastic reset member 14 includes two groups of torsional springs 141. Referring to Figure 5 or Figure 6 , the two-plug protection door 12 is provided with first guide columns 123 on opposite sides, specifically, the outer side wall of the two-plug protection door 12 has oppositely arranged first guide columns 123, and the first guide columns extend along the length direction of the first through hole 1111; the first spring bodies 1411 of the two groups of torsional springs 141 are sleeved on the corresponding first guide columns 123, so as to fix the first spring bodies 141 by using the first guide columns 123; the torsional arms 1412 of the two groups of torsional springs 141 abut to the support seat 11, so as to support the torsional arms 1412 by using the support seat 11. In this way, after the two-plug protection door 12 is pressed, the two groups of torsional springs 141 are driven to move downward and store energy by the corresponding first guide columns 123; after the two-plug protection door 12 is no longer pressed, the two groups of torsional springs 141 push the two-plug protection door 12 back to the original position, that is, reset to the normal state, by the action of the elastic force of the two groups of torsional springs 141.

[0088] Optionally, the two groups of torsion springs 141 can also be replaced by two groups of elastic sheets or two groups of elastic body structures, which have similar working principles to the torsion springs and thus will not be described here.

[0089] It should be noted that the first guide column 123 is a connecting shaft for movably connecting the two-insert protection door 12 with the support base 11, and the first guide column 123 extends along the length direction of the first through hole 1111. For example, referring to Figure 5 or Figure 6 , the number of the first guide column 123 can be two. In addition, each group of torsion springs 141 can include one torsion spring 141 or multiple torsion springs 141, which is not specifically limited here. For example, referring to Figure 5 each group of torsion springs 141 includes one torsion spring 141.

[0090] In another possible implementation, referring to Figure 2 , the first elastic reset member 14 includes a spring body part 142 and two groups of extension arms 143 connected to the two ends of the spring body part 142, the extension arms 143 extend in the outward direction of the radial direction of the spring body part 142, so that the extension arms 143 are located on one side of the spring body part 142; the spring body part 142 is connected to the support base 11 and located around the two-insert protection door 12, and the two groups of extension arms 143 are arranged on the opposite sides of the two-insert protection door 12, respectively. Here, the opposite sides of the two-insert protection door 12 refer to the sides where the first guide columns 123 are located. In actual application, the two groups of extension arms 143 abut against the lower sides of the first guide columns 123 arranged on the opposite sides of the two-insert protection door 12, respectively. In this way, the spring body part 142 is fixed through the support base 11, so as to ensure that the first elastic reset member 14 is firmly arranged on the support base 11; at the same time, since the extension arms 143 abut against the first guide columns 123 of the two-insert protection door 12, when the two-insert protection door 12 is pressed, the two groups of extension arms 143 move under the pushing of the corresponding first guide columns 123 to store energy; when the two-insert protection door 12 is no longer pressed, the spring body part 142 pushes the two-insert protection door 12 back to the original position, i.e., resets to the normal state, under the action of its own elastic force.

[0091] Further, referring to Figure 2The spring body part 142 comprises a connecting arm 1421, two second spring bodies 1422 connected to two ends of the connecting arm 1421, and each second spring body 1422 is further connected to a group of extension arms 143. Thus, when the spring body part 142 is subjected to external force, stress can be dispersed to the two second spring bodies 1422 through the connecting arm 1421, compared with a single spring body structure, stress concentration can be avoided, thereby improving the overall strength and fatigue resistance of the spring body part 142, and buffering can be realized, thereby prolonging the service life.
