In a specific implementation manner, the first jack group 101 at least includes a live wire hole and a neutral wire hole, when the plug is inserted into the live wire hole and the neutral wire hole, the pushing protection door 02 moves towards a direction close to the second jack group 102 so as to expose socket copper pieces corresponding to the live wire hole and the neutral wire hole, and the plug contacts with the socket copper pieces so as to realize electrical connection between the plug and the socket; similarly, the second jack set 102 also includes a live wire hole and a neutral wire hole, and the movement process is similar to that of the live wire hole and the neutral wire hole included in the first jack set 101, which are not described herein again.

In a specific implementation manner, the first jack group 101 and/or the second jack group 102 may further include a ground hole, and the protection door 02 is provided with a avoidance groove 205 corresponding to the position of the ground hole. Through setting up dodging groove 205, can avoid setting up the guide surface that corresponds to the ground wire hole that does not lead to, simplify the structure of protection door 02, save the materials of protection door 02, reduce manufacturing cost.

In a specific implementation manner, as shown in fig. 4 and fig. 6, fig. 4 is a schematic structural diagram of another view angle of a protective door 02 provided in an embodiment of the present application, and fig. 6 is a schematic structural diagram of a platen 03 provided in an embodiment of the present application; the platen 03 is equipped with first guide portion 302 near the protection door 02 side, and protection door 02 is equipped with second guide portion 206 near the platen 03 side, and first guide portion 302 cooperates with second guide portion 206 for protection door 02 moves along first direction X.

The first guide portion 302 and the second guide portion 206 may be guide bars and sliding grooves disposed on the center line of the platen 03, or may be guide bars and sliding grooves symmetrically disposed along the center line of the platen 03, which are not limited in the specific placement positions of the first guide portion 302 and the second guide portion 206 in the embodiment of the present application.

In one embodiment, one of the first guide portion 302 and the second guide portion 206 is a guide bar, and the other is a chute, and the guide bar extends along the first direction X, and is disposed in the chute and is slidably connected with the chute along the first direction X. By arranging the first guide part 302 and the second guide part 206 to limit the movement direction of the protection door 02, the protection door 02 is prevented from deviating from the first direction X in the movement process, the use reliability of the socket is affected, and the use experience of a user is ensured.

Specifically, the first guiding portion 302 may be set as a chute, the second guiding portion 206 may be set as a guiding strip, and the first guiding portion 302 may also be set as a guiding strip, and the second guiding portion 206 is set as a chute.

As shown in fig. 6, in a specific implementation manner, the guide bar is provided with a breaking notch 323, the breaking notch 323 divides the guide bar into a first section 321 close to the first jack group 101 and a second section 322 close to the second jack group 102, the elastic element 04 is placed in the breaking notch 323, and when the plug is inserted into the first jack group 101, the protection door 02 and the second section 322 cooperate to compress the elastic element 04; when the plug is inserted into the second jack group 102, the protection door 02 cooperates with the first segment 321 to compress the elastic member 04.

Assuming that the portion of the protection door 02 and the second section 322 that cooperates with the compression elastic member 04 is a first portion, the portion of the protection door 02 and the first section 321 that cooperates with the compression elastic member 04 is a second portion, and the first portion and the second portion may be the same portion of the protection door 02 or different portions of the protection door 02.

For example, in some embodiments, a protrusion is disposed on the middle portion of the protection door 02 corresponding to the breaking notch 232, the size of the protrusion along the first direction X is smaller than the size of the breaking notch 232 along the first direction X, an elastic member 04 is disposed between the protrusion and the first section 321, another elastic member 04 is disposed between the protrusion and the second section 322, and when the plug is inserted into the first jack group 101, the protrusion is used as a first portion to move along with the protection door 02 toward the second jack group 102, and during the movement, the elastic member 04 located between the protrusion and the second section 322 is compressed in cooperation with the second section 322; when the plug is inserted into the second jack group 102, the projection is moved as the second portion in the direction of the first jack group 101 along with the protection door 02, and compresses the elastic member 04 located between the projection and the first segment 321 in cooperation with the first segment 321 during the movement. In this embodiment, the first portion and the second portion are the same portion on the protection door 02.

In other embodiments, two sets of bumps are disposed on the protection door 02, the two sets of bumps are disposed at two ends of the breaking notch 232 along the first direction X, the bump near the first section 321 avoids the first section 321, the bump near the second section 322 avoids the second section 322, and after the elastic member 04 is installed in the breaking notch 232, two ends of the elastic member initially abut against the first section 321 and the second section 322 respectively. When the plug is inserted into the first jack group 101, the protruding block near the first section 321 serves as a first part to move along with the protection door 02 towards the second jack group 102, and the protruding block cooperates with the second section 322 to compress the elastic piece 04 in the moving process; when the plug is inserted into the second jack group 102, the projection adjacent to the second segment 322 serves as a second portion that moves in the direction of the first jack group 101 along with the protection door 02, and compresses the elastic member 04 in cooperation with the first segment 321 during the movement. In this embodiment, the first portion and the second portion are different portions on the protection door 02.

It will be appreciated that, no matter which part of the protection door 02 is used to compress the elastic member 04, when the plug is pulled out from the first jack group 101 or the second jack group 102, the elastic member 04 can instantaneously release the accumulated elastic potential energy and push the protection door 02 in the process to restore the original position, that is, the state that the elastic member 04 is not subjected to external force, and in this state, the protection door 02 can cover the first jack group 101 and the second jack group 102 at the same time.

Therefore, according to the socket provided in this embodiment of the present application, the breaking notch 323 is provided on the guide strip to accommodate the elastic element 04, when the plug is inserted into the first jack group 101, the protection door 02 cooperates with the second section 322 to compress the elastic element 04, when the plug is separated from the first jack group 101, the elastic element 04 recovers to deform so as to push the protection door 02 to recover to a state of covering the first jack group 101 and the second jack group 102 at the same time, when the plug is inserted into the second jack group 102 and separated from the second jack group 102, the movement principle of the socket protection door 02 is similar to that when the plug is inserted into the first jack group 101 and separated from the first jack group 101, and will not be repeated herein. Through the socket provided by the embodiment of the application, the elastic piece 04 can enable the protection door 02 to recover to the state of covering the first jack group 101 and the second jack group 102 at the same time after the plug is separated from the first jack group 101 or the second jack group 102, so that the use safety of the socket is further ensured.

In a specific implementation manner, fixing devices are respectively disposed on opposite sides of the first section 321 and the second section 322, and specifically, the fixing devices may be protrusions protruding from end surfaces of opposite sides of the first section 321 and the second section 322, and the elastic member 04 may be limited at the location by the protrusions disposed at the location, so as to ensure installation reliability of the elastic member 04. For example, when the elastic member is a cylindrical spring, the protrusion may penetrate into the inner hole of the cylindrical spring, thereby limiting the cylindrical spring to prevent it from being separated from the breaking notch 323 or changing the installation direction.

As shown in fig. 4, in a specific implementation manner, the position of the protection door 02 corresponding to the elastic member 04 is provided with a limit groove 207, and the limit groove 207 is used for limiting the movable space of the elastic member 04.
