Specifically, in the present embodiment, the seat body 1, the protection door 2 and the elastic element 3 are arranged, and the elastic element 3 is arranged on the seat body 1 and connected with the protection door 2; when the elastic element 3 is in the initial state, the two driving inclined planes of the protection door 2 correspondingly cover the two hole positions in the jack one by one, so that when the plug 7 is inserted into the jack, the two conducting strips on the plug 7 can simultaneously act on the two driving inclined planes of the protection door, so that the protection door 2 moves in the guide interval 5 along the first direction until the elastic element 3 is switched to the first state from the initial state; when the plug 7 is pulled out of the jack, the elastic member 3 automatically restores from the first state to the initial state under the action of the restoring force of the elastic member 3, and drives the protective door 2 to move in the process, so that the two driving inclined surfaces of the protective door 2 are covered on the two hole positions in the jack one by one.

Therefore, the socket protection door structure shown in the embodiment realizes electric shock protection of the jack, and the stroke of the protection door moving along the first direction is determined by the insertion depth of the plug 7, so that the moving stroke of the protection door is effectively reduced, the structure is simple, the number of used parts is small, the moving smoothness of the protection door is ensured, and the safety performance is improved.

It should be noted that the jacks shown in the present embodiment include a two-pole jack 41 and a three-pole jack 42. Depending on the jack type, the protective door 2 of the present embodiment is the two-pole protective door 21 when the jack 4 is the two-pole jack 41, and the protective door 2 of the present embodiment is the three-pole protective door 22 when the jack 4 is the three-pole jack 42. In this embodiment, the two-pole jack 41 and the three-pole jack 42 can be separately disposed on the base body 1, and the two-pole jack 41 and the three-pole jack 42 can be simultaneously disposed on the base body 1, which is not limited in this respect.

Meanwhile, the elastic member 3 shown in the present embodiment may be a spring, an elastic needle, an elastic rod, etc. which are well known in the art, and this is not particularly limited.

In addition, the first direction shown in the present embodiment may be specifically a length direction of the seat body 1, and the first direction is perpendicular to an insertion direction of the plug 7 toward the jack 4. In the case of a horizontal arrangement of the seat body 1, the first direction is obviously distributed along the horizontal direction. In order to further ensure the smoothness of the movement of the protection door 2 along the first direction, the present embodiment may provide that the two driving slopes on the protection door 2 are arranged in parallel.

As shown in fig. 3 to 5, in the case where the jack 4 is divided into the two-pole jack 41 and the three-pole jack 42, and the protection door 2 is divided into the two-pole protection door 21 and the three-pole protection door 22, the guide space 5 shown in the present embodiment includes a first guide space 51 and a second guide space 52; a spacing compartment 6 is provided between the first guide spacing 51 and the second guide spacing 52.

In this embodiment, a plurality of first ribs are disposed on the base 1 according to the shape and the moving direction of the diode protection door 21 to form the first guiding space 51. Accordingly, according to the present embodiment, a plurality of second ribs may be disposed on the base 1 to form the second guiding spaces 52 according to the shape and the moving direction of the three-pole protection door 22. Obviously, the present embodiment may locate all or part of the holes of the two-pole jack 41 in the region of the first guide space 51, and locate all or part of the holes of the three-pole jack 42 in the region of the second guide space 52.

As shown in fig. 3, 4 and 6, the diode protection gate 21 of the present embodiment is disposed at the first guide space 51, and a first through hole 210 is disposed between two driving slopes of the diode protection gate 21.

As shown in fig. 3, 4 and 9, the three-pole protection door 22 of the present embodiment is provided in the second guide space 52, and a second through hole 220 is provided between the two driving slopes of the three-pole protection door 22.

Here, for the sake of convenience of distinction, in the present embodiment, the driving slope of the two-pole protection gate 21 is denoted as a first driving slope 201, and the driving slope of the three-pole protection gate 22 is denoted as a second driving slope 202.

As shown in fig. 4, 6 and 7, the two-pole protection door 21 of the present embodiment has a first connecting lug 211 on a side close to the three-pole protection door 22. As shown in fig. 4, 9 and 10, the side of the three-pole protection door 22 close to the two-pole protection door 21 in the present embodiment is provided with a second engaging lug 221; the first connecting lug 211 and the second connecting lug 221 are arranged in the spacing compartment 6 at intervals; one end of the elastic member 3 is connected to the first coupling lug 211, and the other end is connected to the second coupling lug 221.

Therefore, in the present embodiment, based on the same elastic member 3 disposed in the limiting compartment 6, the reset control of the two-pole protective door 21 and the three-pole protective door 22 can be respectively realized, and the overall structure configuration of the socket protective door structure is simplified.

As shown in fig. 4, 5 and 11, when the elastic member 3 is in the initial state, the two driving inclined planes of the two-pole protection door 21 cover the live wire hole site and the neutral wire hole site of the two-pole jack 41 in a one-to-one correspondence, the first through hole 210 corresponds to the ground hole site of the three-pole jack 42, and the two driving inclined planes of the three-pole protection door 22 cover the live wire hole site and the neutral wire hole site of the three-pole jack 42 in a one-to-one correspondence. Here, the present embodiment further compactly combines the two-pole jack 41 and the three-pole jack 42, and when the two-pole plug is inserted into the two-pole jack 41 or the three-pole plug is inserted into the three-pole jack 42, the two-pole protective door 21 and the three-pole protective door 22 can be moved independently without interfering with each other.

As shown in fig. 8, when the two-pole plug is inserted into the two-pole jack 41 of the socket shutter structure, the two conductive strips of the two-pole plug simultaneously act on the two driving inclined planes of the two-pole shutter 21, and the two driving inclined planes of the two-pole shutter 21 are both inclined toward the lower right, so that the first direction shown in this embodiment is horizontal to the left, that is, the two-pole shutter 21 is driven by the two-pole plug to move horizontally to the left in the guide space.

As shown in fig. 4, in this embodiment, when the elastic member 3 is in the initial state, a side of the first connecting lug 211 facing away from the elastic member 3 is attached to a first wall of the spacing compartment 6, a side of the second connecting lug 221 facing away from the elastic member 3 is attached to a second wall of the spacing compartment 6, and the first wall is opposite to the second wall.

Here, the first wall of the spacing compartment 6 shown in the present embodiment can limit the movement of the two-pole protection door 21, and the second wall of the spacing compartment 6 can also limit the movement of the three-pole protection door 22. In the initial state, the elastic member 3 shown in this embodiment may be in a natural extension state or a first compression state; in the first state, the elastic member 3 shown in this embodiment is in the second compressed state; the elastic member 3 is compressed by a greater amount in the second compressed state than in the first compressed state.

In order to better control the movement of the two-pole and three-pole protective doors 21 and 22, the elastic member 3 shown in this embodiment is preferably a spring, and the elastic member 3 is disposed in the spacing compartment 6.

Specifically, in order to facilitate the installation of the spring, in this embodiment, a first limiting shaft 212 is disposed on a side surface of the first connecting lug 211 facing the elastic member 3, a second limiting shaft 222 is disposed on a side surface of the second connecting lug 221 facing the elastic member 3, the spring is disposed between the opposite end surfaces of the first connecting lug 211 and the second connecting lug 221, one end of the spring is sleeved on the first limiting shaft 212, and the other end of the spring is sleeved on the second limiting shaft 222.

The cross-sectional shapes of the first limiting shaft 212 and the second limiting shaft 222 shown in the present embodiment may be circular, triangular, square, hexagonal, or the like, and are not limited herein.

As shown in fig. 1, fig. 2, fig. 5 and fig. 11, the seat body 1 of the present embodiment includes a first housing 11 and a second housing 12; the first shell cover 11 and the second shell cover 12 are assembled into a whole along the height direction of the seat body 1, and an accommodating cavity is formed between the first shell cover 11 and the second shell cover 12; the jacks on the first shell cover 11 correspond to the jacks on the second shell cover 12 one by one, and the guide spaces 5 are arranged in the accommodating cavities.

Here, in order to simplify the structure, the socket protection door structure may be disposed in the housing of the socket in the embodiment; the seat body 1 shown in this embodiment does not include the first housing, the specific shape of the seat body 1 refers to the second housing 12 shown in the above embodiment, the guiding spaces are disposed on the second housing 12, and the insertion holes on the second housing 12 are disposed in one-to-one correspondence with the respective hole positions of the insertion holes disposed on the upper surface of the housing.

Next, the socket protection door structure shown in the present embodiment will be specifically described by taking the base 1 provided with the first housing 11 and the second housing 12 as an example.

Preferably, in a case where the seat body 1 includes the first housing 11 and the second housing 12, the thickness of the protection door is gradually reduced from the middle to both ends of the protection door 2 in the first direction.

Here, the thickness of the protection door 2 is optimized in the present embodiment, on one hand, when the plug 7 is inserted into the insertion hole and acts on two driving slopes on the protection door 2 at the same time, it is ensured that the protection door 2 can move smoothly along the first direction, and the contact friction resistance between the seat body 1 and the protection door 2 is reduced, and on the other hand, when the conducting strip of the plug is inserted into one of the hole sites of the insertion hole, because the conducting strip only acts on one of the driving slopes on the protection door, the protection door can rotate with its middle portion as a pivot point, and there is an abundant space in the seat body 1 instead of moving horizontally along the first direction, so as to ensure that the driving slopes on the protection door can still cover the corresponding hole sites, and avoid generating an electric shock risk.

As shown in fig. 3 to 4, a side surface of the protection door 2 facing the first housing 11 and a side surface of the protection door 2 facing the second housing 12 in the embodiment are provided with a rotating shaft structure 9, and a cross-sectional shape of the rotating shaft structure 9 on a vertical plane along the first direction is triangular or arcuate.

The triangle shown in the present embodiment is preferably an isosceles triangle, and the arc shape shown in the present embodiment is preferably a semicircle.

Here, in order to further avoid the risk of electric shock when the conductive sheet is inserted into the jack, in this embodiment, a blocking rib 8 is disposed on a side surface of the second casing 12 facing the protection door, and the blocking rib 8 is disposed on one side of the hole site corresponding to the jack on the second casing 12; in the case where a single conductive piece passes through the insertion hole and acts on the driving slope on the protective door, the blocking rib 8 is brought into abutment with the protective door in the first direction to stop the protective door from moving in the first direction.

As shown in fig. 3 and 11, since the two driving inclined planes of the two diode protection doors 21 and the two driving inclined planes of the three-pole protection door 22 are opposite in inclination direction during actual installation, under the condition that the two diode jacks 41 and the three-pole jack 42 are simultaneously arranged on the second housing 12, the blocking rib 8 is arranged on the left side of the zero line hole site and the left side of the live line hole site close to the two diode jacks 41, and the blocking rib 8 is arranged on the right side of the zero line hole site and the right side of the live line hole site close to the three-pole jack 42.

As shown in fig. 12, when a single conductive strip is inserted into the live line hole in the dipole insertion hole 41, the dipole protection door 21 rotates counterclockwise around the middle thereof as a pivot until the left end of the dipole protection door 21 abuts against the blocking rib 8 on the left side of the live line hole. At this time, the diode protection door 21 does not move leftward due to the blocking effect of the blocking rib 8, so that the risk of electric shock caused by the conductive sheet passing through the live wire hole of the diode insertion hole 41 can be prevented.

As shown in fig. 13, when a single conductive strip is inserted into the neutral line hole position in the two-pole jack 41, the two-pole protective door 21 rotates clockwise with the middle thereof as a fulcrum until the right end of the two-pole protective door 21 abuts against the blocking rib 8 on the left side of the neutral line hole position. At this time, the two-pole protection door 21 does not move leftward due to the blocking effect of the blocking rib 8, so that the risk of electric shock caused by the conductive sheet passing through the neutral hole of the two-pole jack 41 can be prevented.

As shown in fig. 14, when a single conductive strip is inserted into the live wire hole in the three-pole jack 42, the three-pole protection door 22 rotates clockwise with the middle thereof as a pivot until the right end of the three-pole protection door 22 abuts against the blocking rib 8 on the right side of the live wire hole. At this time, the three-pole protection door 22 does not move to the right due to the blocking effect of the blocking rib 8, so that the electric shock risk caused by the conductive sheet passing through the live wire hole of the three-pole jack 42 can be prevented.

As shown in fig. 15, when a single conductive strip is inserted into the neutral line hole in the three-pole jack 42, the three-pole protective door 22 rotates counterclockwise around the middle thereof as a pivot until the left end of the three-pole protective door 22 abuts against the blocking rib 8 on the right side of the neutral line hole. At this time, due to the blocking effect of the blocking rib 8, the three-pole protection door 22 does not move rightward, so that the electric shock risk caused by the fact that the conducting strip penetrates through the zero line hole of the three-pole jack 42 can be prevented.

In fig. 12 to 15, the arrow on the conductive sheet side indicates the insertion direction of the conductive sheet toward the insertion hole.

In addition, the blocking rib 8 may be provided on a side of the first housing 11 facing the protection door. Specifically, as shown in fig. 12 to 13, the left and right side blocking ribs 8 for the secondary protection door 21 are located on the second housing 12 on the lower side of the secondary protection door 21, which is particularly advantageous in optimizing the space design inside the protection door and optimizing the relationship between the shape and the degree of rotation of the protection door.

Of course, as another alternative (not shown in the drawings), the blocking ribs 8 for both left and right sides of the diode protection door 21 may be provided in the first housing 11 on the upper side of the diode protection door 21. In the case that a single conductive plate passes through the insertion hole of the first housing 11 and acts on the driving slope of the diode protection door 21, the diode protection door 21 rotates on the second housing 12, causing the blocking rib 8 of the first housing 11 to abut against the diode protection door 21 in the first direction to stop the diode protection door 21 from moving in the first direction. In addition, the same applies to the three-pole protection door 22, and the description thereof is omitted.

In addition, the present embodiment may also be provided with a blocking rib 8 on a side surface of the protection door facing the second housing 12, and the blocking rib on the protection door is arranged near the insertion hole on the second housing (not shown in the drawing). As shown in fig. 12 to 13, in this embodiment, two blocking ribs may be disposed on the lower side of the two-pole protection door 21, and the two blocking ribs correspond to the live wire hole site and the neutral wire hole site of the two-pole jack 41 one-to-one. Under the condition that a single conducting strip passes through the jack on the first shell and acts on the driving inclined plane of the two-pole protective door 21, the blocking rib on the two-pole protective door 21 extends into the live wire hole position or the zero wire hole position on the second shell 12 to stop the two-pole protective door 21 from moving along the first direction. In addition, the same applies to the three-pole protection door 22, and the description thereof is omitted.

As shown in fig. 1 and 2, under the condition that the seat body 1 includes the first housing 11 and the second housing 12, the first housing 11 and the second housing 12 shown in this embodiment are connected through a plug structure, the plug structure includes a plug pin and a plug hole separately disposed on the first housing 11 and the second housing 12, and/or the first housing 11 and the second housing 12 are connected through a clamping structure, and the clamping structure includes a clamping rib and a buckle separately disposed on the first housing 11 and the second housing 12.

Here, in order to ensure convenience and reliability of connection between the first housing 11 and the second housing 12, in this embodiment, an insertion structure and a clamping structure are simultaneously provided between the first housing 11 and the second housing 12.

In actual installation, in this embodiment, the plug pin 110 disposed on the first housing 11 may be inserted into the insertion hole 120 disposed on the second housing 12, and then the buckle 111 disposed on the first housing 11 is clamped in the clamping rib 121 disposed on the second housing 12, so as to achieve the fastening connection between the first housing 11 and the second housing 12.

The cross section of the plug shown in this embodiment may be circular, square or triangular, which is not limited in this respect. The plug and the jack shown in the embodiment can be inserted in an interference fit insertion mode.
