Description

Anti-creeping socket

Technical Field

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

Background

The socket is a common electric connector in daily life, and when the socket is used, the socket can be connected with the house for electricity. Wherein a user is in need of the socket when using the socket.

In order to improve the electricity safety and reduce the personal damage caused by electric shock, the household distribution boxes of civil electricity or industrial electricity are provided with leakage protection switches. When the electric appliance is leaked, the electric appliance shell and the live wire are usually led to be conducted, the electric appliance shell is electrified, and when the electric appliance shell is electrified, a user contacts the electric appliance shell, an electric shock accident occurs, so that the electric appliance shell needs a grounding wire, when the electric appliance is leaked, the electric appliance shell is equivalent to the conduction of the live wire and the grounding wire, and is connected with the grounding wire, at the moment, the electric shock accident does not occur when the user contacts the electric appliance shell, but at the moment, the grounding wire is conducted with the live wire, and current passes through the grounding wire. Therefore, when the current appears in the ground wire, the potential safety hazard of the leakage of the electric appliance can be reversely presumed, and when a certain current exists in the ground wire circuit, the leakage protection switch cuts off the power supply circuit to ensure the electricity safety.

The presence of current in the ground means that the ground is conductive with the live line, but the ground is conductive with the live line, not all because of electrical leakage. Any part of the power line is conducted with the ground wire, and current can occur in the ground wire. In actual work and life, a more general condition is that the socket accidentally intakes water to lead to live wire and ground wire in the socket to switch on through water, leads to appearing the electric current in the ground wire, and earth leakage protection switch can not distinguish the electric current in the ground wire and produce because of what, so, earth leakage protection switch also can cut off the power consumption circuit this moment, but the socket accidentally intakes water, and the water in the socket has just switched on live wire and zero line, has then been equivalent to having inserted a resistance between live wire and zero line, and water can be evaporated by fever to can not cause the influence to normal power consumption. However, if the water in the socket turns on the live wire and the ground wire, the leakage protection switch is triggered, so that the whole circuit is cut off if not necessary, and thus the prior art still needs to be further improved.

The socket is a common electric connector in daily work and life, and when the socket is used, the socket can be used for supplying electricity for people or industry. When current exists in the ground wire in the circuit, the leakage protection switch cuts off the circuit for safety, but the circuit is not required to be cut off in all the situations that the ground wire has current, for example, when water flows into the cavity from the jack, the water is communicated with the live wire and the ground wire, so that the ground wire has current, and the leakage protection switch also cuts off the circuit. Furthermore, the receptacle water intake is typically after an accident, and handling the accident is typically required to maintain a normal supply of power, and if the power is cut off unnecessarily after the accident, it is inconvenient to handle, and even impossible to handle in time.

In order to solve the problem that the leakage protection switch cuts off the circuit under the unnecessary condition, the patent provides an anti-leakage 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. 1-3, 6, 12-14 and 16, an anti-leakage socket, comprising: the live wire unit 100, the live wire unit 100 includes the plug-in part 110 of the live wire and live wire extension 120, the plug-in part 110 of the live wire is used for plugging in with the plug pin of the live wire, the extension 120 of the live wire is connected with plug-in part 110 of the live wire electrically, and is used for connecting with the live wire electrically; the neutral unit 200, the neutral unit 200 includes a neutral plug part 210 and a neutral extension part 220, the neutral plug part 210 is used for plugging with a neutral pin, and the neutral extension part 220 is electrically connected with the neutral plug part 210 and is used for electrically connecting with a neutral wire; the ground wire unit 300, the ground wire unit 300 includes a ground wire insertion portion 310 and a ground wire extension portion 320, the ground wire insertion portion 310 is used for being inserted with a ground wire pin, and the ground wire extension portion 320 is electrically connected with the ground wire insertion portion 310 and is used for being electrically connected with a ground wire; the casing is provided with a bottom shell 700 and a baffle 400, the baffle 400 is transversely arranged, a containing cavity 500 is formed above the baffle 400, an isolation cavity 600 is formed below the baffle 400, and a through hole is formed in the baffle 400; the live wire unit 100 is positioned in the accommodating cavity 500, the ground wire extension part 320 is positioned in the isolating cavity 600, and the ground wire plug part 310 penetrates out of the through hole; or, the ground wire unit 300 is located in the accommodating cavity 500, the live wire extension 120 is located in the isolating cavity 600, and the live wire plug-in portion 110 is penetrated out of the through hole.

In this embodiment, the live wire and the ground wire inside the socket are separated, after a small amount of water enters the socket, the water entering the socket flows into the isolation cavity 600 through the through hole, so that the live wire and the ground wire are prevented from being conducted by water, and the situation that the leakage protection switch is unnecessarily disconnected from the circuit due to the conduction of the live wire and the ground wire can be avoided.

The socket normally uses unexpected water inflow, which is mostly unexpected splash, and the water inflow is relatively small, so that the embodiment can avoid the situation that the circuit is unnecessarily cut off by a plurality of leakage protection switches.

However, there is a lot of water inflow from the socket in individual cases, and in this case, in the above embodiment, water may overflow from the inside of the isolation chamber 600 into the receiving chamber 500, resulting in conduction between the live wire and the ground wire.

In order to avoid unnecessary circuit disconnection of the leakage protection switch caused by water inlet of the socket as much as possible, the application also provides another embodiment. In this embodiment, a hollow boss 410 is disposed above the partition 400 at a through hole, an opening is disposed at an upper end of the hollow boss 410, the through hole is disposed at a lower end of the hollow boss 410, and a live wire plug-in portion 110 or a ground wire plug-in portion 310 is disposed in the hollow boss 410. At this time, when the socket is in water, the water can be split into two parts of the isolation cavity 600 and the accommodating cavity 500, the hollow boss 410 can prevent the water entering the accommodating cavity 500 from flowing into the isolation cavity 600, and the water entering the isolation cavity 600 enters through the opening of the hollow boss 410, so that the actual water inflow is smaller, and the water accumulation in the isolation cavity 600 is less, therefore, the occurrence of the condition that the leakage protection switch is unnecessarily disconnected due to the fact that the socket is accidentally in water for conducting the live wire and the ground wire can be more effectively avoided.

In this embodiment, the opening at the upper end of the hollow boss 410 is used for inserting the plug pin into the hollow boss 410, and is electrically connected to the live wire plug-in portion 110 or the ground wire plug-in portion 310 disposed in the hollow boss 410. A receiving chamber 500 is formed above the partition 400 and outside the hollow boss 410, and the receiving chamber 500 can receive the first combination (the live wire unit 100 and the neutral wire unit 200) and the second combination (the ground wire unit 300 and the neutral wire unit 200), and specifically which combination is received can be determined according to whether the live wire unit 100 or the ground wire unit 300 is provided in the isolation chamber 600. The live wire unit 100 is located in the accommodating chamber 500, and the ground wire unit 300 is located in the isolating chamber 600; or, the ground wire unit 300 is located in the accommodating cavity 500, and the live wire unit 100 is located in the isolating cavity 600, so that the live wire and the ground wire are respectively located in different spaces, and the socket is not easy to be conducted after water enters, so that unnecessary tripping of the power utilization line (the leakage protection switch cuts off the power supply circuit) is not easy to be caused. In addition, the implementation modes of the accommodating cavity 500 and the isolating cavity 600 formed above and below the partition 400 respectively enable the overall structure to be concise, the routing modes of the live wire unit 100, the ground wire unit 300 and the neutral wire unit 200 are not limited by the partition 400, and the routing modes are more flexible.

When the live wire unit 100 is located in the isolation chamber 600, the neutral wire unit 200 and the ground wire unit 300 are located in the receiving chamber 500, the live wire unit 100 and the neutral wire unit 200 are not conducted by water to generate heat because the live wire unit 100 is located in the isolation chamber 600, the neutral wire unit 200 is located in the receiving chamber 500, and the live wire unit 100 and the neutral wire unit 200 are isolated from each other, in addition to the effect of preventing unnecessary tripping and the effect of preventing overheating of the socket.

It should be noted that, when water is introduced into the socket during use, water needs to be discharged from the socket. Specific implementation satisfying the above needs the present embodiment is not limited, and for ease of understanding, the present application provides a preferred implementation.

In this embodiment, the upper surface of the partition 400 is inclined, and the partition 400 has a first end 400a located at a high position and a second end 400b located at a low position, so that water entering the receiving chamber 500 flows to the second end 400b. A water passing hole 420 is opened at the second end 400b such that water flowing to the second end 400b flows out of the receiving chamber 500 from the water passing hole 420. A first drain hole 710 communicating the water passing hole 420 with the outside of the housing is provided under the water passing hole 420, so that water flowing out of the receiving chamber 500 from the water passing hole 420 flows out of the socket from the first drain hole 710.

It should be noted that, based on the technical scheme that the upper end of the hollow column 720 is located in the first annular wall 430, the water flowing through the water hole 420 is guided to the water drain hole in the hollow column 720, and further, there is a technical problem how to prevent overflow when the water flows into the hollow column 720. In order to solve the above problems, the present application provides a preferred implementation.

It should be noted that the first annular groove 440 has various implementations. Specific implementation satisfying the above needs the present embodiment is not limited, and for ease of understanding, the present application provides a preferred implementation.

In this embodiment, the upper surface of the bottom plate inside the third annular wall 730 is inclined, so that the water in the isolation chamber 600 flows toward the fourth end 750 and flows out of the housing from the second drain hole 760.

It should be noted that when the socket enters more water, for example, in such an extreme case that the socket is immersed in water, the live wire unit 100 and the ground wire unit 300 located in the accommodating chamber 500 and the isolating chamber 600 are still turned on by the water, so that a current is generated in the ground wire, thereby causing the leakage protection switch to cut off the circuit.

At this time, after the socket is taken out of the water, the water in the socket flows out through the drain hole, and according to the technical effect of providing the drain hole, the residual water only adheres to the surfaces of the parts of the socket, and no water accumulation is formed inside the socket. The residual water may still be conducted to the ground and live units 300, 100 and another embodiment is proposed in order to exclude as far as possible the tripping caused in this case. In this embodiment, the first end 400a is on the same side as the fourth end 750, the second end 400b is on the same side as the third end 740, at this time, the first drain hole 710 and the second drain hole 760 are far away from each other, and the path for conducting the water layers of the ground wire unit 300 and the live wire unit 100 is longer, and the resistance is larger, so that even if the ground wire unit is conducted, the current is smaller, and under the condition that the water layers are thin, the current generated in the ground wire unit 100 and the ground wire unit 300 are conducted, so that the leakage protection switch is not enough to trigger, thus unnecessary tripping can be avoided as much as possible, so that under emergency conditions, the supply of electric power can be ensured, the power is prevented from being cut off due to accidents, and meanwhile, the unexpected problem can be solved quickly due to the power consumption is needed.

In the case that the plug is inserted into the socket, water is splashed onto the socket and is not easy to enter water through the plug-in position of the plug and the socket, but the socket is usually provided with a plurality of jack units for inserting and taking electricity, when only part of the plug is inserted into the socket, the water splashed onto the socket is easy to flow into the socket from the jack of the plug, and when the water flows to the pin position of the plug inserted into the socket, the live wire pin and the ground wire pin of the plug inserted into the socket are easy to be conducted, so that tripping is caused, and in order to avoid unnecessary tripping in the situation, in one embodiment, a shelf 800 is arranged above the partition board, a hole position for the plug pin to pass through is formed in the shelf 800, and a protective door 802 is arranged above the shelf 800; the partition board is provided with a convex wall 801 extending upwards around the hole site corresponding to the ground wire, and the ground wire pins are inserted from the convex wall 801.

The guard gate 802 may reduce the amount of water that spills onto the receptacle into the receptacle, the raised wall 801 above the shelf 800 surrounding the ground jack may enclose the ground pin of the plug such that in the presence of a small amount of water above the shelf 800, the ground pin and the hot pin will not conduct, and will not trigger the safety protection switch, avoiding unnecessary tripping. In addition, the shelf 800 is arranged, so that water splashed to the socket flows down through the jack after entering through the jack of the socket, and flows into the through hole of the baffle plate below the jack from the jack, so that the water can be guided to the isolation cavity 600 and the containing cavity 500, and when a small amount of water enters, the metal parts of the isolation cavity 600 and the containing cavity 500 can not be conducted, and current can not be generated in the ground wire due to accidental water entering of the socket, and unnecessary tripping can not be caused.

Normally, the ground wire is grounded, the ground voltage is zero, the zero wire is not grounded, but the ground voltage is zero, but when the electric power is actually used, some anomalies may exist, so that although the electric power can be normally used, the ground power supply of the zero wire is not zero, when the ground voltage of the zero wire is not zero, if the zero wire and the ground wire are conducted, current is generated in the ground wire, and the leakage protection switch may be caused to recognize the dangerous condition of electric leakage in the electric power circuit, so that the leakage protection switch trips. The zero line to ground voltage is not zero, the value of the zero line to ground voltage is usually very small, if the ground wire and the zero line are conducted by water at this time, the current generated in the ground wire is too small, so that the leakage protection switch is not cut off, but when the socket is practically and accidentally splashed with liquid, tap water, rainwater, tea water, wine water, soup and the like are usually present, and ions for enhancing the conductivity of the liquid exist in the soup, so that under the situation that the socket is accidentally splashed with the soup, if the zero line to ground voltage is not zero, relatively large current is generated in the ground wire, so that the leakage protection switch is cut off, and unnecessary tripping is caused.

In order to solve the unnecessary trip caused by this accidental factor, the present invention also proposes an embodiment capable of further preventing the unnecessary trip based on the foregoing embodiment, referring to fig. 18 and 19.

In this embodiment, a dividing weir 900 is further provided in the accommodating chamber 500, and when the ground wire unit 300 is located in the accommodating chamber 500 and the live wire extension 120 is located in the isolating chamber 600, the neutral wire unit 200 or the ground wire unit 300 is located in the dividing weir 900. The liquid entering the jack of the socket corresponding to the dividing weir 900 and the liquid entering from other jacks of the socket are divided by the dividing weir 900 and cannot be communicated, so that when the socket is accidentally splashed with the liquid with high conductivity, the liquid can be prevented from conducting the zero line unit and the ground line unit in the accommodating cavity, and unnecessary tripping caused by the liquid can be avoided.

In addition, when the live wire unit 100 is positioned in the receiving chamber 500 and the ground extension 320 is positioned in the isolating chamber 600, the neutral wire unit 200 or the live wire unit 100 is positioned in the dividing weir 900. The liquid entering through the jack corresponding to the dividing weir of the socket and the liquid entering through other jacks of the socket are divided by the dividing weir 900 and cannot be communicated, so that when the socket is accidentally splashed with the liquid with high conductivity, the liquid conducts the live wire and the zero wire in the accommodating cavity, and the short circuit and overheat of the live wire and the zero wire in the socket are avoided.

In addition to the division of the accommodation chamber by the dividing weir 900, a cofferdam 901 may be used, so that when the live wire extension 120 is located in the isolation chamber 600 and the neutral wire unit 200 and the ground wire unit 300 are located in the accommodation chamber 500, the neutral wire plugging portion 210 or the ground wire plugging portion 310 in the accommodation chamber 500 are separately separated, and the role of avoiding the conduction between the neutral wire and the ground wire can be played. When the socket is splashed with liquid with stronger conductivity under the actual use scene, the amount of liquid which can enter the socket is very small, the cofferdam 901 is adopted to separate the earth wire plug-in part or the zero wire plug-in part, so that the liquid which enters from the earth wire plug-in hole or the zero wire plug-in hole is enclosed by the cofferdam and cannot flow to other parts in the socket, the space in the socket is larger, and the liquid which can enter from the plug-in hole can not normally conduct the earth wire extension part and the zero wire extension part, therefore, the cofferdam 901 is arranged in the accommodating cavity 500, and the problem that the socket can not conduct the zero wire and the earth wire due to unexpected entering of the liquid with stronger conductivity, and the earth wire generates current to cause the leakage protection switch to cut off current can be solved. Likewise, when the ground wire extension part is positioned in the isolation cavity, and the live wire unit and the neutral wire unit are positioned in the containing cavity, short-circuit overheating of the live wire and the neutral wire in the socket can be avoided when the socket is accidentally splashed with liquid with high conductivity.
