As an important interface for power transmission, the safety of sockets is directly related to the life and property safety of users. In recent years, due to improper use of sockets or design defects, electric shock accidents have occurred frequently, especially the increase in children's electric shock accidents, which has attracted much attention to the safety problems of sockets.

[0003] However, although there are already many socket products with safety doors on the market, the designs and qualities of the safety doors are uneven, and some products still have problems such as unsmooth plugging and unplugging and insufficient safety performance. Summary of the Utility Model

[0004] In order to solve the problems of unsmooth plugging and unplugging and insufficient safety performance existing in the prior art, the present application provides a magnetic safety door structure and a socket.

[0005] In order to achieve the above object, the technical solution adopted in the present application is as follows: a magnetic safety door structure, including: at least one contact system disposed in the housing, any contact system includes a moving piece and a static piece, the moving piece is slidably disposed in the housing, the moving piece is fixed in the housing, and the moving piece can abut against the static piece; a spring is disposed between the housing and the moving piece, a first magnetic energy storage member for stretching the spring is disposed between the housing and the moving piece, and a second magnetic energy storage member for compressing the spring is further disposed between the moving piece and the housing. When the spring is in its original length state, the moving piece is located between the first magnetic energy storage member and the second magnetic energy storage member.

[0006] In some embodiments of the present utility model, the first magnetic energy storage member includes a first magnetic block and a second magnetic block with a different magnetic property from the first magnetic block. The first magnetic block is disposed at one end of the moving piece, the second magnetic block is disposed on the inner wall of the housing, and the first magnetic block abuts against the second magnetic block.

[0007] In some embodiments of the present utility model, the second magnetic energy storage member includes a third magnetic block and a fourth magnetic block with a different magnetic property from the third magnetic block. The third magnetic block is disposed at the other end of the moving piece, the fourth magnetic block is disposed on the inner wall of the housing, and the third magnetic block abuts against the fourth magnetic block.

[0008] In some embodiments of the present utility model, a slot for connecting with a plug is disposed on the moving piece.

[0009] In some embodiments of the present utility model, a guiding assembly is provided inside the housing. The guiding assembly includes vertical plates and sliders. There are two vertical plates, both of which are vertically arranged inside the housing. A guiding gap is formed between the two vertical plates. A sliding groove for accommodating the slider is formed on the inner side wall of the vertical plate. The slider is arranged on the moving piece.

[0010] The present utility model also provides a socket, including a magnetic safety door structure.

[0011] Beneficial effects:

[0012] 1. In the above contact system, the moving piece and the static piece are separately arranged. When the socket insert is inserted, the moving piece is pushed to abut against the static piece to achieve electrical connection of the circuit. When the plug is not inserted, the moving piece is not energized, and no electric arc is generated when the plug contacts the moving piece, avoiding damage to the plug insert caused by the electric arc. When the moving piece and the static piece are in contact and the circuit is connected, the secondary electrical connection and arc transfer between the moving piece and the static piece improve the safety of using the safety door structure.

[0013] 2. The above spring is used to drive the separation of the moving piece and the static piece. When the socket is unplugged, the spring returns to its original length and drives the separation of the moving piece and the static piece. The above first magnetic energy storage element is used to stretch the spring through magnetic attraction. When the plug is inserted into the socket, the moving piece quickly moves to the position of the static piece, which can reduce the generation of electric arcs. When the moving piece and the static piece are in contact, the magnetic force of the second magnetic energy storage element contracts the spring, thereby storing the kinetic energy for the separation of the moving piece and the static piece.

[0025] Embodiment 1

[0026] Please refer to Figure 1 and Figure 2 , this embodiment provides a magnetic - adsorption type safety door structure, including: at least one contact system 2 arranged in the housing 1, any contact system 2 includes a moving piece 201 and a static piece 202. The moving piece 201 is slidably arranged in the housing 1, fixed in the housing 1, and the moving piece 201 can abut against the static piece 202; A spring 3 is arranged between the housing 1 and the moving piece 201, and a first magnetic energy storage component for stretching the spring 3 is arranged between the housing 1 and the moving piece 201. A second magnetic energy storage component for compressing the spring 3 is also arranged between the moving piece 201 and the housing 1. When the spring 3 is in its original length state, the moving piece 201 is located between the first magnetic energy storage component and the second magnetic energy storage component.

[0027] In this embodiment, the above - mentioned contact system 2 separates the moving piece 201 and the static piece 202. When the inserted socket blade pushes the moving piece 201 to abut against the static piece 202 in contact, the circuit is thus turned on. When the plug is not inserted, the moving piece 201 is not energized, so when the plug contacts the moving piece 201, no electric arc will be generated, avoiding damage to the plug blade caused by the generation of an electric arc. When the moving piece 201 and the static piece 202 are in contact and the circuit is connected, the secondary power connection and arc transfer between the moving piece 201 and the static piece 202 improve the safety of using the safety door structure.

[0028] In this embodiment, the above - mentioned spring 3 is used to drive the separation of the moving piece 201 and the static piece 202. When the socket is unplugged, the spring 3 returns to its original length and drives the separation of the moving piece 201 and the static piece 202; The above - mentioned first magnetic energy storage element is used to stretch the spring 3 through magnetic attraction. When the plug is inserted into the socket, the moving piece 201 can quickly move to the position of the static piece 202, reducing the generation of an electric arc; When the moving piece 201 and the static piece 202 are in contact, the magnetic force of the second magnetic energy storage element contracts the spring 3, thereby storing the kinetic energy for the separation of the moving piece 201 and the static piece 202.

[0029] Please refer to Figure 1 and Figure 2 , in some implementation manners of this embodiment, the above - mentioned first magnetic energy storage component includes a first magnetic block 4 and a second magnetic block 5 with a different magnetic property from the first magnetic block 4. The first magnetic block 4 is arranged at one end of the moving piece 201, and the second magnetic block 5 is arranged on the inner wall of the housing 1, and the first magnetic block 4 abuts against the second magnetic block 5.

[0030] In this embodiment, the above - mentioned first magnetic block 4 and second magnetic block 5 attract each other, and the magnetic force between the first magnetic block 4 and the second magnetic block 5 stretches the spring 3. When the plug is inserted into the socket, the thrust of the operator's hand separates the first magnetic block 4 and the second magnetic block 5, and the spring 3 continuously returns to its original length. When the spring 3 oscillates at the original length position, the interaction of the second magnetic energy storage component stretches the spring 3, thereby adsorbing and abutting the plug against the static piece 202.

[0031] Please refer to Figure 1 and Figure 2 In some embodiments of the present embodiment, the second magnetic energy storage member includes a third magnetic block 6 and a fourth magnetic block 7 having a different magnetism from the third magnetic block 6. The third magnetic block 6 is disposed at the other end of the moving piece 201, and the fourth magnetic block 7 is disposed on the inner wall of the housing 1, and the third magnetic block 6 abuts against the fourth magnetic block 7.

[0032] In this embodiment, the third magnetic block 6 and the fourth magnetic block 7 attract each other to compress the spring 3 in the original length position, so that the moving piece 201 abuts against the static piece 202 to achieve electrical connection, which can assist the entry of the plug of the operator's hand, achieve quick electrical connection, and can effectively transfer the position where the arc is generated, thereby greatly improving the service life of the plug.

[0033] Please refer to Figure 1 and Figure 2 In some embodiments of the present embodiment, a slot 8 for connecting with the plug is provided on the moving piece 201.

[0034] In this embodiment, the slot 8 is used to clamp the insertion piece of the plug when the plug is inserted, thereby effectively improving the stability when the plug is inserted. And a magnetic block is provided at one end of the moving piece 201 near the installation slot 8, which can adsorb the insertion piece of the plug and improve the stability of the plug insertion and extraction.

[0035] Please refer to Figure 1 and Figure 2 In some embodiments of the present embodiment, a guiding assembly is provided in the housing 1. The guiding assembly includes a vertical plate 9 and a slider 10. There are two vertical plates 9, and both vertical plates 9 are vertically disposed in the housing 1. A guiding gap is formed between the two vertical plates 9. A sliding groove 11 for accommodating the slider 10 is formed on the inner side wall of the vertical plate 9, and the slider 10 is disposed on the moving piece 201.

[0036] In this embodiment, the guiding assembly is used to position and guide the movement of the moving piece 201, so that the movement of the moving piece 201 always moves along the direction of the sliding groove 11, thereby greatly improving the safety of sliding. Specifically, the slider 10 disposed on the moving piece 201 and the sliding groove 11 formed on the vertical plate 9 are in clearance fit, which can avoid the swing of the insertion piece during sliding and affect the stress concentration of the external force on the spring 3, improve the service life of the spring 3, and also improve the stability of the contact electrical connection.

[0037] In use, the user holds the socket by hand and inserts the blade of the plug into the jack 12 of the socket. As the blade continuously enters the jack 12, it drives the separation of the first magnetic block 4 and the second magnetic block 5. After the first magnetic block 4 and the second magnetic block 5 are separated, the spring 3 continuously returns to its original length. When the spring 3 is in the original length position, the third magnetic block 6 and the fourth magnetic block 7 interact, and the spring 3 is compressed, attracting the fixed piece to the position of the moving piece 201 for contact and power connection.

[0038] Embodiment 2

[0039] Please refer to Figure 1 - Figure 3 , this embodiment also provides a socket, including a magnetic attraction type safety door structure. The above-mentioned magnetic attraction type safety door structure improves the safety of the use of the safety door structure through secondary power connection and arc transfer, so that the socket has the same beneficial effects as the magnetic attraction type safety door structure.

[0040] The above are only the preferred embodiments of the present application and are not used to limit the present application. For those skilled in the art, various changes and modifications can be made to the present application. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present application shall be included in the protection scope of the present application.
