The socket is an electrical appliance commonly used in daily life, and if water, conductive liquid and the like enter the socket, safety accidents can be caused, so that users are required to be safe for the socket.

For example, when the pins are not inserted into the sockets, the sockets are required to be in a sealed state, preventing water and conductive liquid from entering the inside of the socket. When the pins are required to be inserted into the insertion holes to achieve electrical connection, the insertion holes are required to be in an open state to allow the pins to be inserted, but at the same time, it is required to prevent foreign substances other than the pins from being inserted into the socket.

In order to solve the above problems, the present patent provides a safety socket, which aims to solve the problem that foreign matters can be easily inserted into the socket.

For ease of understanding, the following detailed description of embodiments of the application is provided with reference to the accompanying drawings.

Referring to fig. 1-2 and 7, the safety socket of the present application includes a bottom case 100; the panel unit 200, the panel unit 200 includes a first housing 210, the first housing 210 is disposed above the bottom case 100; the first housing 210 is provided with an insertion hole 211; a protective door 300 for sealing the insertion hole 211 when the pins are not inserted into the insertion hole 211; the protective door 300 is disposed below the first housing 210 and abuts against the first housing 210; the jack 211 includes a neutral jack 211b and a live jack 211a, and the safety socket further includes a first stopper 400a near the neutral jack 211b, the first stopper 400a being at least partially overlapped with the protective door 300 in both the insertion direction of the jack 211 and the direction of vertical jack insertion in the state where the protective door 300 is in the blocking state of the jack 211; the first stopper 400a is used to prevent the sliding of the protective door 300 when pins or other objects that can be inserted into the insertion holes 211 are individually inserted into the fire wire insertion holes 211 a.

In this embodiment, a protective door 300 is disposed below the first housing 210, and opens the jack when the protective door is pushed by the pins, and slides from the neutral jack to the live jack. The structure of this embodiment is described based on the sliding of the guard gate from the neutral jack to the hot jack. It should be noted that, in other embodiments, if the sliding direction of the protection door is set from the live wire jack to the neutral wire jack, there is no substantial difference from the present embodiment, and those skilled in the art will certainly recognize that the structure of the implementation in which the sliding opening direction of the protection door is set from the live wire jack to the neutral wire jack is not substantially different from the present embodiment.

The protection door 300 is attached to the first housing, so that the protection door 300 can seal the insertion hole 211 when the socket is not used, and a certain waterproof effect is achieved. The abutment of the shield door 300 against the first housing 210 is not limited to the abutment of the shield door 300 against the inner side surface of the first housing 210, but has a force approaching toward the first housing 210 by the restoring mechanism.

The plug pins of the electric appliance can be inserted into the insertion holes 211 when the socket is required to be used. When the socket is not in use, in order to prevent the non-electric plug pins from pushing the protective door 300, the first stop part 400a is provided near the neutral wire insertion hole 211b, so that when an object of the non-electric plug pins, such as a single pin or a metal needle-shaped or sheet-shaped component, is individually inserted into the live wire insertion hole 211a, one end of the protective door 300 near the live wire insertion hole 211a is deflected downward by force, one end of the protective door 300 near the neutral wire insertion hole 211b is not pressed downward, and the protective door 300 and the first stop part are overlapped, so that when the protective door is individually pushed by a foreign object inserted into the live wire insertion hole, the first stop part 400a is blocked, so that the protective door 300 cannot slide to one side, and thus the protective door cannot be opened, preventing the foreign object from being inserted into the live wire insertion hole 211a, thereby causing an electric shock accident.

When the wiring of the external power utilization line meets the specification, the zero line plug connector in the zero line jack is connected with the zero line in the external power supply line, and the fire wire plug connector in the fire wire jack is connected with the fire wire in the external power supply line. The electric shock accident can not be caused by the fact that the zero line is touched independently, but in the connection of the actual electric line, the phenomenon that part of the zero line and the live line are connected reversely exists, namely the line which is the zero line is connected with the live line, and the line which is the live line is connected with the zero line. The reverse connection of the zero line and the live line does not affect the normal electricity utilization and use, but a certain safety risk exists. In order to prevent the problem of the possibility of electric shock accident when the foreign matter is inserted into the neutral jack of the socket in the case of reverse connection of the neutral and live wires of the power supply line or in the case of other line faults, based on the technical scheme that the first stop part 400a is arranged near the neutral jack 211b, the application further provides an embodiment which can prevent the foreign matter from being inserted into the socket when the foreign matter is independently inserted into the neutral jack.

Referring to fig. 2, the safety socket further includes a second stopper 400b adjacent to the live wire insertion hole 211a, the second stopper 400b preventing the sliding of the protective door 300 when a pin or other object insertable into the insertion hole 211 is individually inserted into the neutral wire insertion hole 211 b.

In this embodiment, by providing the second stop portion 400b near the live wire insertion hole 211a, when a single pin or a metal needle-shaped or sheet-shaped component is individually inserted into the neutral wire insertion hole 211b, one end of the protective door 300 near the live wire insertion hole 211a cannot slide to open the insertion hole due to the locking of the second stop portion 400b, so that the protective door 300 is limited to slide, and the protective door 300 is still in a state of blocking the insertion hole 211.

It should be noted that the position of the first stop 400a and/or the second stop 400b opposite to the case unit 200 has various implementations. Specific implementation satisfying the above needs the present embodiment is not limited, and for ease of understanding, two preferred implementations are provided.

Mode one.

Referring to fig. 2, the first stop portion 400a and/or the second stop portion 400b are disposed on an inner side surface of the first housing 210.

In this embodiment, the first stop portion 400a and/or the second stop portion 400b are disposed on the inner side surface of the first housing 210, so that if one end of the protective door 300 cannot move downward, the end is blocked by the first stop portion 400a or the second stop portion 400b and cannot slide laterally to open the insertion hole 211. That is, when only one insertion hole 211 is inserted into an insertable object, an end portion of the shield door 300 adjacent to the other insertion hole 211 does not move downward because it is not subjected to downward force, and is blocked by the first stopper 400a or the second stopper 400b from moving laterally when it is subjected to lateral force, thereby achieving the purpose of preventing insertion of a monopole or a foreign object.

And a second mode.

Referring to fig. 1-2, the panel unit 200 includes a second housing 220, the second housing 220 is located below the first housing 210, and the protection door 300 is located between the first housing 210 and the second housing 220; the first stop portion 400a and/or the second stop portion 400b are disposed on the upper surface of the second housing 220.

In this embodiment, the face-piece unit 200 includes a second housing 220, the second housing 220 is located below the first housing 210, and the protection door 300 is located between the first housing 210 and the second housing 220; the first stopper 400a and/or the second stopper 400b are provided on the upper surface of the second housing 220 such that when only one insertion hole 211 is inserted into the insertable object, one end of the protective door 300 near the inserted object is deflected downward to abut against the first stopper 400a or the second stopper 400b, thereby preventing the insertable object from being inserted further inward, and achieving the purpose of preventing the insertion of a monopole or a foreign object. When the plug pins are inserted into the jacks, the protective door integrally moves downwards and cannot deflect, so that the protective door cannot be abutted with the stop parts, and the jacks can be normally and transversely slid to be opened.

It should be noted that, the position of the first stop portion 400a or the second stop portion 400b relative to the protection door 300 has various implementations. Specific implementation satisfying the above needs the present embodiment is not limited, and for ease of understanding, two preferred implementations are provided.

Referring to fig. 2, the first stop portion 400a or the second stop portion 400b is located at an end of the protection door 300 when the protection door 300 closes the insertion hole 211.

In this embodiment, when the protection door 300 closes the insertion hole 211, the first stop portion 400a or the second stop portion 400b is located at the end of the protection door 300, so that when the protection door 300 is pressed and swung by an object inserted into the single insertion hole 211, the end of the protection door can abut against the first stop portion 400a or the second stop portion 400b.

And a second mode.

Referring to fig. 4, one end of the protection door 300 is provided with a through hole 320, and the second stop portion 400b or the first stop portion 400a is located at the through hole 320 when the protection door 300 closes the insertion hole 211. The through hole 320 is located at an end portion of the shield door 300 upstream in the sliding direction.

When the first stop portion 400a or the second stop portion 400b is located at the end of the protection door 300, that is, near one end of the protection door 300, may be located outside or inside the end of the solid structure of the protection door 300.

In this embodiment, one end of the protection door 300 is provided with a through hole 320, and when the protection door 300 blocks the insertion hole 211, the first stop portion 400a or the second stop portion 400b is located in the through hole 320, so that when the protection door 300 swings by being pressed by an object inserted into the single insertion hole 211, the protection door 300 can abut against the first stop portion 400a or the second stop portion 400b.

It should be noted that, to solve the above problem, it is necessary to provide a force to the inner side of the first housing 210 to the protective door 300 so that the protective door 300 can move to a position to close the insertion hole 211 when the plug pins are not inserted into the insertion hole 211 and when the plug pins are pulled out of the insertion hole 211, and the following scheme is further provided.

In this embodiment, the safety socket is provided with a reset mechanism 500, and the reset mechanism 500 includes a first reset member 510, so that when the plug pin is pulled out, the protection door 300 is driven to reset and a force towards the inner side surface of the first housing 210 is provided for the protection door 300, so that the protection door 300 seals the insertion hole 211. Meanwhile, the first reset piece 510 can also realize the effect of plugging the jack 211 when the plug pins are not inserted.

It should be noted that the first reset element 510 has various implementations. Specific implementation satisfying the above needs the present embodiment is not limited, and for ease of understanding, two preferred implementations are provided.

Mode one.

Optionally, the first reset element 510 is configured as a first magnet and a second magnet, where the first magnet is disposed on the protective door 300, and the first magnet and the second magnet attract each other or repel each other.
