Description

A leakage-proof socket Technical Field

The invention relates to the technical field of sockets, and in particular to an anti-leakage socket.

Background Art

Sockets are common electrical appliances in daily life. When water enters the socket, the live wire terminal and the ground wire terminal are connected by the water, causing current to be generated in the ground wire line. The leakage protection switch will disconnect due to detection of the current in the ground wire line. This is one of the reasons for "tripping", that is, the live wire terminal and the ground wire terminal in the socket are connected, causing tripping.

The function of the ground wire is to ground the outer casing of the appliance to prevent electric shock accidents when the user touches the outer casing of the appliance. When a leakage protection switch is connected to the line, if current is detected in the ground wire, the leakage protection switch will be triggered to cut off the power supply circuit. However, the ground wire detection switch cannot distinguish whether the ground wire current comes from leakage of the appliance. When water enters the socket and causes the ground wire and the live wire to be connected, the leakage protection switch will also detect the existence of current in the ground wire, thereby triggering leakage protection.

Electric shock accidents usually occur when a person stands on the ground and touches the live wire, which makes the person, as a conductor, connect the live wire and the ground, and form an electric current in the person, thus causing an electric shock accident. In addition, if there is no other conductive circuit between the live wire and the neutral wire or between the live wire and the ground wire, and the person touches the live wire and the neutral wire or the live wire and the ground wire at the same time, it will also form an electric current in the person, causing an electric shock accident.

When water accidentally enters the socket, it is usually not pure water. The water that enters the socket can act as a conductor to connect the live wire and the neutral wire, as well as the live wire and the ground wire. Water entering the socket alone will not directly cause an electric shock accident, but it will cause the leakage protection switch to operate due to the conduction of the live wire and the ground wire, resulting in unnecessary tripping, making the entire power supply circuit unable to supply power, and causing unnecessary trouble for the normal power use of other electrical appliances in the power supply circuit and the elimination of local line faults.

Therefore, the sockets in the prior art have the problem that water entering one of the sockets in the circuit causes the live wire and the ground wire in the circuit to be connected, causing the leakage protection switch to operate and cut off the power supply of the entire circuit.

When water enters the socket, the live wire terminal and the ground wire terminal are connected by the water, causing current to be generated in the ground wire line. The leakage protection switch will disconnect due to detection of the current in the ground wire line. This is one of the reasons for "tripping", that is, the live wire terminal and the ground wire terminal in the socket are connected, causing tripping.

The function of the ground wire is to ground the outer casing of the appliance to prevent electric shock accidents when the user touches the outer casing of the appliance. When a leakage protection switch is connected to the line, if current is detected in the ground wire, the leakage protection switch will be triggered to cut off the power supply circuit. However, the ground wire detection switch cannot distinguish whether the ground wire current comes from leakage of the appliance. When water enters the socket and causes the ground wire and the live wire to be connected, the leakage protection switch will also detect the existence of current in the ground wire, thereby triggering leakage protection.

Electric shock accidents usually occur when a person standing on the ground touches the live wire, making the human body a conductor. If the live wire and the neutral wire are connected, current will be formed in the human body, resulting in an electric shock accident. In addition, if there is no other conductive circuit between the live wire and the neutral wire or the live wire and the ground wire, and the human body touches the live wire and the neutral wire or the live wire and the ground wire at the same time, current will be formed in the human body, resulting in an electric shock accident.

When water accidentally enters the socket, it is usually not pure water. The water that enters the socket can act as a conductor to connect the live wire and the neutral wire, as well as the live wire and the ground wire. Water entering the socket alone will not directly cause an electric shock accident, but it will cause the leakage protection switch to operate due to the conduction of the live wire and the ground wire, resulting in unnecessary tripping, making the entire power supply circuit unable to supply power, and causing unnecessary trouble for the normal power use of other electrical appliances in the power supply circuit and the elimination of local line faults.

In order to solve the above problems, an embodiment of the present application provides a leakage-proof socket to solve the problem that in the existing power supply circuit, if any socket with a ground wire accidentally enters with water, it will cause the leakage protection switch to detect the leakage current and then cut off the entire power supply circuit when it is not necessary.

For ease of understanding, the specific implementation of the embodiments of the present application is described in detail below with reference to the accompanying drawings.

Please refer to Figures 1-2 and Figures 7-11, a leakage-proof socket, the leakage-proof socket includes: a shell 100, the shell 100 includes a bottom shell unit 110 and a surface shell unit 120; a ground wire plug compartment 200 and a live wire plug compartment 300 are formed in the shell 100, and the ground wire plug compartment 200 and the live wire plug compartment 300 are isolated from each other; a ground wire connector is arranged in the ground wire plug compartment 200, and a live wire connector is arranged in the live wire plug compartment 300; a cofferdam 400 is formed around the upper part of the opening of the ground wire plug compartment 200, a ground wire separation chamber 130 is formed inside the cofferdam 400, and a ground wire jack 210 is formed in the ground wire separation chamber 130 in the surface shell.

The ground wire plug compartment 200 and the live wire plug compartment 300 formed in the housing 100 are isolated from each other, so that when water or conductive liquid enters the ground wire plug compartment 200 or the live wire plug compartment 300, the ground wire and the live wire will not be connected. In addition, the ground wire plug compartment 200 refers to a space for accommodating a ground wire connector. A cofferdam 400 is formed around the upper part of the opening of the ground wire plug compartment 200, and a ground wire separation chamber 130 is formed inside the cofferdam 400. The surface housing forms a ground wire plug hole 210 in the ground wire separation chamber 130, so that when water or conductive liquid enters, due to the separation effect of the cofferdam 400, the water or conductive liquid can only enter the ground wire plug compartment 200 or the live wire plug compartment 300 alone, and the ground wire in the ground wire plug compartment 200 and the live wire in the live wire plug compartment 300 will not be connected through water or conductive liquid. In this way, the problem in the existing power supply circuit that if any socket with a ground wire accidentally enters with water, the leakage protection switch will detect the leakage current and then cut off the entire power supply circuit when it is not necessary is solved.

At present, for the sake of electrical safety, sockets need to be equipped with protective doors to prevent live parts from coming out of the sockets. The exposed protective door structure is usually set on the surface shell unit 120, and water or conductive liquid usually enters from the surface shell unit 120. Therefore, the separation effect of the cofferdam 400 is required to act on the water or conductive liquid entering from the surface shell unit 120.

Wherein, please refer to Figures 1-2 and 6-9. In a preferred embodiment, the surface shell unit 120 includes a first shell 121 and a second shell 122.

The second shell 122 is arranged above the first shell 121, and the cofferdam 400 is located between the first shell 121 and the second shell 122.

In this embodiment, the second shell 122 is arranged above the first shell 121, so that the separation effect of the cofferdam 400 can act on the surface shell unit 120, thereby enhancing the anti-leakage function of the socket. The cofferdam 400 is located between the first shell 121 and the second shell 122, so that the water or conductive liquid entering from the surface shell unit 120 can be separated by the cofferdam 400, so that the ground wire in the ground wire plug compartment 200 and the live wire in the live wire plug compartment 300 cannot be connected through water or conductive liquid.

It should be noted that the present embodiment can be applied to a wall plug, the bottom shell unit 110 can be embedded in the wall, and the surface shell unit 120 faces the outside of the wall.

Optionally, the decorative panel 800 is fixed on top of the surface shell unit 120 .

It should be noted that the separation effect of the cofferdam 400 is required to enable water or conductive liquid to enter only the ground plug compartment 200 or the live plug compartment 300, so that the ground wire in the ground plug compartment 200 and the live wire in the live plug compartment 300 are not connected through water or conductive liquid. The specific implementation method that meets the above requirements is not limited in this embodiment. For ease of understanding, this application provides two preferred implementation methods.

In this embodiment, the cofferdam 400 is formed by the second housing 122 protruding downward, so as to separate the inside of the ground wire separation chamber 130 from the outside. Therefore, water or conductive liquid can only enter the ground wire plug compartment 200 or the live wire plug compartment 300 under the separation effect of the cofferdam 400, so that the ground wire in the ground wire plug compartment 200 and the live wire in the live wire plug compartment 300 will not be connected through water or conductive liquid.

Method 2.

In this embodiment, the upper edge of the cofferdam 400 is higher than the opening of the fire plug compartment 300, so that the cofferdam 400 can The separation effect can be generated so that water or conductive liquid can only enter the ground wire plug compartment 200 or the live wire plug compartment 300, so that the ground wire in the ground wire plug compartment 200 and the live wire in the live wire plug compartment 300 will not be connected through the water or conductive liquid.

Please refer to Figures 12-13, the bottom shell unit 110 includes a third shell 123 extending upward, a ground wire plug compartment 200 is formed in the third shell 123, the top of the third shell 123 passes through the first shell 121 upward, and the part of the third shell 123 passing through the first shell 121 forms a cofferdam 400.

In this embodiment, the third shell 123 extends upward, and a ground plug compartment 200 is formed in the third shell 123, so that the ground plug compartment 200 and the live plug compartment 300 are isolated from each other. The top of the third shell passes through the first shell 121 upward, and the part of the third shell 123 passing through the first shell 121 forms a cofferdam 400, so that water or conductive liquid entering from the surface shell unit will not enter the live plug compartment 300 after entering the ground plug hole 210.

It should be noted that, in order to further prevent water or conductive liquid from connecting the ground wire and the live wire, it is required that when the ground wire pin is not inserted into the ground wire jack 210, the ground wire jack 210 is in a closed state, or when the plug pin is not inserted into the live wire jack 310, the live wire jack 310 is in a closed state.

It should be noted that after the water or conductive liquid that enters the socket from the housing unit 120, it is required that the water or conductive liquid can be discharged from the socket. The specific implementation method that meets the above requirements is not limited in this embodiment. For ease of understanding, this application provides a preferred implementation method.

Please refer to FIGS. 1-5 , the housing 100 is provided with a drainage hole 700 , and the drainage hole 700 is located between the first housing 121 and the second housing 122 .

In this embodiment, drainage holes 700 are provided at the first shell 121 and the second shell 122, so that water or conductive liquid entering from the housing unit 120 can be discharged from the socket after entering the socket. Moreover, the drainage holes 700 will not affect the separation function of the cofferdam 400 while discharging water or conductive liquid.

The embodiment of the present application provides another anti-leakage socket.

The present embodiment is different from the previous embodiment in that the leakage-proof socket includes a shell, which can effectively protect the socket unit and can also effectively reduce the water and conductive liquid that enter from the surface shell unit 120. The shell 100 includes a bottom shell unit 110 and a surface shell unit 120, so that the inside of the shell 100 is isolated from the outside. The ground wire plug compartment 200 and the live wire plug compartment 300 formed in the shell 100 are isolated from each other, so that water or conductive liquid cannot enter. When the ground wire plug compartment 200 or the live wire plug compartment 300 is inserted, the ground wire and the live wire will not be connected.

At present, for the sake of electrical safety, the socket needs to be equipped with a protective door to prevent the live parts from being exposed from the socket. The protective door structure is usually set on the surface shell unit 120, and water or conductive liquids usually enter from the surface shell unit 120. Therefore, the separation effect of the cofferdam 400 is required to act on the water or conductive liquids entering from the surface shell unit 120.

Among them, please refer to Figures 1-2 and 6-9. In a preferred embodiment, the surface shell unit 120 includes a first shell 121 and a second shell 122. The first shell 121 is fixed to the bottom shell unit 110. A live wire plug compartment 300 and a ground wire plug compartment 200 are formed below the first shell 121. The second shell 122 is arranged above the first shell 121, and the cofferdam 400 is located between the first shell 121 and the second shell 122.

In this embodiment, the second shell 122 is arranged above the first shell 121, so that the separation effect of the cofferdam 400 can act on the surface shell unit 120, thereby enhancing the anti-leakage function of the socket. The cofferdam 400 is located between the first shell 121 and the second shell 122, so that the water or conductive liquid entering from the surface shell unit 120 can be separated by the cofferdam 400, so that the ground wire in the ground wire plug compartment 200 and the live wire in the live wire plug compartment 300 cannot be connected through water or conductive liquid.

It should be noted that, since this embodiment has a housing, this embodiment can be applied to a power strip.

Optionally, the decorative panel 800 is fixed on top of the surface shell unit 120 .

It should be noted that the separation effect of the cofferdam 400 is required to enable water or conductive liquid to enter only the ground plug compartment 200 or the live plug compartment 300, so that the ground wire in the ground plug compartment 200 and the live wire in the live plug compartment 300 are not connected through water or conductive liquid. The specific implementation method that meets the above requirements is not limited in this embodiment. For ease of understanding, this application provides two preferred implementation methods.

In this embodiment, the upper edge of the cofferdam 400 is higher than the opening of the live wire plug compartment 300, so that the cofferdam 400 can produce a separation effect, which allows water or conductive liquid to only enter the ground wire plug compartment 200 or the live wire plug compartment 300, so that the ground wire in the ground wire plug compartment 200 and the live wire in the live wire plug compartment 300 will not be connected through water or conductive liquid.

Please refer to Figures 12-13, the bottom shell unit 110 includes a third shell 123 extending upward, a ground wire plug compartment 200 is formed in the third shell 123, the top of the third shell 123 passes through the first shell 121 upward, and the part of the third shell 123 passing through the first shell 121 forms a cofferdam 400.

In this embodiment, the third shell 123 extends upward, and a ground plug compartment 200 is formed in the third shell 123, so that the ground plug compartment 200 and the live plug compartment 300 are isolated from each other. The top of the third shell 123 passes through the first shell 121 upward, and the part of the third shell 123 passing through the first shell 121 forms a cofferdam 400, so that water or conductive liquid entering from the surface shell unit will not enter the live plug compartment 300 after entering the ground plug hole 210.

It should be noted that, in order to further prevent water or conductive liquid from connecting the ground wire and the live wire, the ground wire jack 210 is in a closed state when the ground wire pin is not inserted into the ground wire jack 210. The specific implementation method that meets the above requirements is not limited in this embodiment. For ease of understanding, this application provides a preferred implementation method.

Please refer to Figure 4. A ground wire protection mechanism 500 is set in the ground wire separation chamber 130; the ground wire protection mechanism 500 includes a ground wire protection door 510 and an elastic reset mechanism 520. The ground wire protection door 510 is used to block the ground wire jack 210 when the ground wire pin is not inserted into the ground wire jack 210, and the elastic reset mechanism 520 is used to reset the ground wire protection door 510 when the ground wire pin is pulled out of the ground wire jack 210.

In this embodiment, the protection mechanism is disposed in the ground wire separation chamber 130, so that the effect of the protection mechanism closing the ground wire jack 210 not only does not affect the separation function of the cofferdam 400, but can also strengthen the separation function of the cofferdam 400. The ground wire protection mechanism 500 includes a ground wire protection door 510 and an elastic reset mechanism 520, so that when the ground wire pin is not inserted into the ground wire jack 210, the ground wire jack 210 is in a closed state.

In summary, the leakage-proof socket provided in the embodiment of the present application includes a shell and a socket unit arranged in the shell, wherein the socket unit includes: a shell 100, wherein the shell 100 includes a bottom shell unit 110 and a surface shell unit 120; a ground wire plug compartment 200 and a live wire plug compartment 300 are formed in the shell, wherein the ground wire plug compartment 200 and the live wire plug compartment 300 are isolated from each other; a ground wire connector is arranged in the ground wire plug compartment 200, and a live wire connector is arranged in the live wire plug compartment 300; a cofferdam 400 is formed around the upper part of the opening of the ground wire plug compartment 200, wherein the cofferdam 400 and the surface shell unit 120 form a ground wire separation chamber 130, and the surface shell forms a ground wire jack 210 in the ground wire separation chamber 130. Thus, the problem that the leakage protection switch detects leakage current due to accidental water ingress into any socket with a ground wire in the existing power supply circuit is solved, thereby cutting off the entire power supply circuit when it is not necessary.
