Description

Technical Field

[0001] The utility model relates to the technical field of sockets, in particular to an anti-leakage socket. Background Art

[0002] Sockets are common electrical connectors in daily life. When the sockets are used, they are connected to residential electricity. When users use the sockets, they have a demand for the sockets.

[0003] In order to improve the safety of electricity use and reduce personal injury caused by electric shock, household distribution boxes for civil or industrial electricity are equipped with leakage protection switches. When an electrical appliance leaks electricity, it usually causes the housing of the appliance to be connected to the live wire, and the housing of the appliance is charged. If the user touches the housing of the appliance at this time, an electric shock accident will occur. Therefore, the housing of the appliance needs to be connected to the ground wire. When the electrical appliance leaks electricity, it is equivalent to the live wire being connected to the ground wire. The housing of the appliance is connected to the ground wire. At this time, the user touches the housing of the appliance and there will be no electric shock accident. However, at this time, the ground wire is connected to the live wire, and there is current passing through the ground wire. Therefore, when current appears in the ground wire, it can be reversely inferred that there is a safety hazard of leakage of the electrical appliance. Therefore, when a certain current is detected in the ground wire circuit, the leakage protection switch will cut off the power supply circuit to ensure the safety of electricity use.

[0004] The presence of current in the ground wire means that the ground wire is connected to the live wire, but the connection between the ground wire and the live wire is not always caused by leakage of electrical appliances. In the power circuit, if the live wire and the ground wire are connected at any point, current will appear in the ground wire circuit. In actual work and life, a more common situation is that the socket is accidentally flooded with water, causing the live wire and the ground wire in the socket to be connected through water, resulting in current in the ground wire. The leakage protection switch cannot distinguish why the current in the ground wire is generated, so at this time, the leakage protection switch will also cut off the power circuit, but if the socket is accidentally flooded, if the water in the socket connects the live wire and the neutral wire, it is equivalent to connecting a resistor between the live wire and the neutral wire. The water will be heated and evaporated, and will not affect normal power consumption. However, if the water in the socket connects the live wire and the ground wire, it will trigger the leakage protection switch, causing the entire circuit to be cut off when it is not necessary, so the existing technology still needs further improvement.

[0047] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0048] It should be noted that if the embodiments of the present invention involve directional indications (such as up, down, left, right, front, back...), the directional indications are only used to explain the relative position relationship, movement status, etc. between the components under a certain specific posture (as shown in the accompanying drawings). If the specific posture changes, the directional indication will also change accordingly.

[0049] In addition, if there are descriptions involving "first", "second", etc. in the embodiments of the utility model, the descriptions of "first", "second", etc. are only used for descriptive purposes and cannot be understood as indicating or suggesting their relative importance or implicitly indicating the number of the indicated technical features. Therefore, the features defined as "first" and "second" may explicitly or implicitly include at least one of the features. In addition, the technical solutions between the various embodiments can be combined with each other, but they must be based on the ability of ordinary technicians in the field to implement them. When the combination of technical solutions is contradictory or cannot be implemented, it should be deemed that such a combination of technical solutions does not exist and is not within the scope of protection required by the utility model.

[0050] Sockets are common electrical connectors in daily work and life. When in use, sockets are connected to civil or industrial electricity. When there is current in the ground wire of the circuit, the leakage protection switch will cut off the circuit for safety reasons. However, not all situations where there is current in the ground wire require the circuit to be cut off. For example, when water flows into the cavity from the socket, the water connects the live wire and the ground wire, causing current in the ground wire. The leakage protection switch will also cut off the circuit. In addition, water usually enters the socket after an accident occurs. Dealing with accidents usually requires maintaining a normal supply of electricity. If the power is cut off unnecessarily after an accident occurs, it will be very inconvenient to deal with it, or even cannot be dealt with in time.

[0051] In order to solve the problem that the leakage protection switch cuts off the circuit when it is not necessary, this patent provides a leakage-proof socket.

[0052] 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.

[0053] See also Figure 1-3 , Figure 6 , Figure 12-14 and Fig.16 A leakage-proof socket, comprising: a live wire unit 100, the live wire unit 100 comprising a live wire plug-in portion 110 and a live wire extension portion 120, the live wire plug-in portion 110 being used to be plugged into a live wire pin, the live wire extension portion 120 being electrically connected to the live wire plug-in portion 110 and being used to be electrically connected to the live wire; a neutral wire unit 200, the neutral wire unit 200 comprising a neutral wire plug-in portion 210 and a neutral wire extension portion 220, the neutral wire plug-in portion 210 being used to be plugged into a neutral wire pin, the neutral wire extension portion 220 being electrically connected to the neutral wire plug-in portion 210 and being used to be electrically connected to the neutral wire; a ground wire unit 300, the ground wire unit 300 comprising a ground wire plug-in portion 310 and a ground wire extension portion 320, the ground wire plug The connecting part 310 is used to be plugged into the ground wire pin, the ground wire extension part 320 is electrically connected to the ground wire plug-in part 310, and is used to be electrically connected to the ground wire; the shell body is provided with a bottom shell 700 and a partition 400, the partition 400 is arranged horizontally, a accommodating cavity 500 is formed above the partition 400, an isolation cavity 600 is formed below the partition 400, and the partition 400 is provided with a through hole; the live wire unit 100 is located in the accommodating cavity 500, the ground wire extension part 320 is located in the isolation cavity 600, and the ground wire plug-in part 310 passes through the through hole; or, the ground wire unit 300 is located in the accommodating cavity 500, the live wire extension part 120 is located in the isolation cavity 600, and the live wire plug-in part 110 passes through the through hole.

[0054] This embodiment separates the live wire and the ground wire inside the socket. After a small amount of water enters the socket, the water entering the socket will flow into the isolation cavity 600 through the through hole, preventing the live wire and the ground wire from being connected by water, thereby preventing the leakage protection switch from unnecessarily cutting off the circuit.

[0055] Accidental water ingress during normal use of a socket is mostly due to accidental splashing, and the amount of water ingress is relatively small. Therefore, this embodiment can avoid the situation where most leakage protection switches cut off the circuit unnecessarily.

[0056] However, there are also individual cases where a large amount of water enters the socket. In this case, in the above embodiment, water may overflow from the isolation cavity 600 into the accommodating cavity 500, causing conduction between the live wire and the ground wire.

[0057] In order to avoid the unnecessary circuit cutting of the leakage protection switch caused by water inflow into the socket as much as possible, the present application also proposes another embodiment. In this embodiment, a hollow boss 410 is provided at the through hole above the partition 400, the upper end of the hollow boss 410 has an opening, the through hole is located at the lower end of the hollow boss 410, and the live wire plug-in part 110 or the ground wire plug-in part 310 is provided in the hollow boss 410. At this time, when water enters the socket, the incoming water will be diverted to the isolation chamber 600 and the accommodating chamber 500. The hollow boss 410 can prevent the water entering the accommodating chamber 500 from flowing into the isolation chamber 600, and the water entering the isolation chamber 600 enters through the opening of the hollow boss 410. The actual water inflow flow is smaller, and the water accumulation in the isolation chamber 600 is relatively less. Therefore, this embodiment can more effectively avoid the situation where the leakage protection switch causes unnecessary circuit cutting due to accidental water inflow into the socket to connect the live wire and the ground wire.

[0058] In this embodiment, the opening at the upper end of the hollow boss 410 is used for the plug pin to be inserted into the hollow boss 410 and electrically connected to the live wire plug-in portion 110 or the ground wire plug-in portion 310 disposed in the hollow boss 410. An accommodating cavity 500 is formed above the partition 400 and outside the hollow boss 410. The accommodating cavity 500 can accommodate the first combination (live wire unit 100 and neutral wire unit 200) and the second combination (ground wire unit 300 and neutral wire unit 200). Which combination is specifically accommodated can be determined according to whether the isolation cavity 600 is provided with the live wire unit 100 or the ground wire unit 300. 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 chamber 500, and the live wire unit 100 is located in the isolating chamber 600, so that the live wire and the ground wire are respectively in different spaces, and the socket is not easily turned on after water enters, and it is not easy to cause unnecessary tripping of the power line (the leakage protection switch cuts off the power supply circuit). In addition, the accommodating chamber 500 and the isolating chamber 600 are respectively formed above and below the partition 400, so that the overall structure is simple, and the routing method of the live wire unit 100, the ground wire unit 300 and the neutral wire unit 200 will not be restricted by the partition 400, and the routing method is more flexible.

[0059] It should be noted that when the live wire unit 100 is located in the isolation cavity 600 and the neutral wire unit 200 and the ground wire unit 300 are located in the accommodating cavity 500, in addition to isolating the live wire unit 100 from the ground wire unit 300 to achieve the effect of preventing unnecessary tripping, it also has the effect of preventing the socket from overheating, because the live wire unit 100 is located in the isolation cavity 600 and the neutral wire unit 200 is located in the accommodating cavity 500, the live wire unit 100 is isolated from the neutral wire unit 200, so the live wire unit 100 and the neutral wire unit 200 will not be heated by water conduction.

[0060] It should be noted that when water enters the socket during use, the water needs to be drained 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.

[0061] See also Figure 3-4 , Fig. 9 , Figure 14-15 and Fig.17 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; the partition 400 is provided with a water hole 420, and the water hole 420 is opened at the second end 400b; a first drainage hole 710 is provided below the water hole 420, and the first drainage hole 710 connects the water hole 420 and the outside of the shell.

[0062] 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 accommodating chamber 500 will flow to the second end 400b. A water hole 420 is provided at the second end 400b, so that the water flowing to the second end 400b flows out of the accommodating chamber 500 from the water hole 420. A first drain hole 710 is provided below the water hole 420, connecting the water hole 420 and the outside of the housing, so that the water flowing out of the accommodating chamber 500 from the water hole 420 flows out of the socket from the first drain hole 710.

[0063] It should be noted that the drain hole has a variety of implementations. The specific implementation that meets the above requirements is not limited in this embodiment. For ease of understanding, this application provides a preferred implementation.

[0064] See also Figure 9-11 and Fig.17 The shell body has a bottom shell 700 , and the bottom shell 700 is provided with a hollow column 720 extending up and down, and a first drainage hole 710 is formed in the hollow column 720 .

[0065] In this embodiment, in the implementation method of forming the first drainage hole 710 in the hollow column 720 extending up and down, the bottom shell 700 can be separated from the partition 400 by a certain distance to make room for the isolation cavity 600 below the partition 400, thereby facilitating the routing of the live wire extension part 120 or the ground wire extension part 320.

[0066] It should be noted that, based on the technical solution of forming the drainage hole in the hollow column 720, there is a further technical problem of how to make the water at the water hole 420 flow to the drainage hole in the hollow column 720. In order to solve the above problem, the present application provides a preferred implementation.

[0067] See also Figure 6-7 and Fig.16 A first annular wall 430 extending downward is provided on the lower side of the partition 400 at the water hole 420 , and the upper end of the hollow column 720 is located in the first annular wall 430 .

[0068] In this embodiment, the upper end of the hollow column 720 is located in the first annular wall 430, so that water at the water hole 420 will flow along the first annular wall 430, enter the hollow column 720, and flow out of the shell from the drainage hole.

[0069] It should be noted that, based on the technical solution that the upper end of the hollow column 720 is located in the first annular wall 430, the water passing through the water hole 420 is guided to flow to the drainage hole in the hollow column 720. Further, there is a technical problem of how to prevent the water from overflowing when it flows into the hollow column 720. In order to solve the above problem, the present application provides a preferred implementation.

[0070] See also Figure 6-7 and Fig.16 A first annular groove 440 is formed in the first annular wall 430 , and the upper end of the hollow column 720 is embedded in the first annular groove 440 .

[0071] In this embodiment, a first annular groove 440 is formed in the first annular wall 430, and the upper end of the hollow column 720 is embedded in the first annular groove 440, so that water from the water hole 420 will directly enter the hollow column 720 without overflowing from the gap between the upper end of the hollow column 720 and the first annular wall 430.

[0072] It should be noted that there are multiple implementations of the first annular groove 440. The specific implementation that meets the above requirements is not limited in this embodiment, and for ease of understanding, this application provides a preferred implementation.

[0073] See also Figure 6-7 and Fig.16The partition plate 400 is provided with a second annular wall 450 extending downward at the lower side of the water hole 420 . The second annular wall 450 is located inside the first annular wall 430 . A first annular groove 440 is formed between the second annular wall 450 and the first annular wall 430 .

[0074] In this embodiment, a first annular groove 440 is formed between the second annular wall 450 and the first annular wall 430 , so that the upper end of the hollow column 720 can be firmly embedded in the first annular groove 440 , thereby preventing water from overflowing.

[0075] It should be noted that there are many implementations for forming the isolation cavity 600 below the partition 400. The specific implementation that meets the above requirements is not limited in this embodiment, and for ease of understanding, this application provides a preferred implementation.

[0076] See also Figure 9-11 and Fig.17 The bottom shell 700 is provided with an upward third annular wall 730 , and the third annular wall 730 is enclosed with the partition plate 400 to form an isolation chamber 600 inside.

[0077] In this embodiment, the third annular wall 730 and the partition plate 400 are enclosed to form an isolation chamber 600 inside, which can effectively prevent water from entering the isolation chamber 600, thereby connecting the live wire unit 100 and the ground wire unit 300.

[0078] It should be noted that there are many implementations of the third annular wall 730 and the partition plate 400 enclosing to form the isolation chamber 600. The specific implementation that meets the above requirements is not limited in this embodiment, and for ease of understanding, this application provides a preferred implementation.

[0080] In this embodiment, the third annular wall 730 abuts against the second annular groove 460 , so that the third annular wall 730 is firmly embedded in the second annular groove 460 , thereby forming the isolation cavity 600 .

[0081] It should be noted that, based on the technical solution of enclosing the isolation chamber 600 with the third annular wall 730 and the partition plate 400, there is a further technical problem of how to drain water when water enters the isolation chamber 600. In order to solve the above problem, the present application provides a preferred implementation.

[0082] See also Figure 9-11 and Fig.17The upper surface of the bottom shell 700 inside the third annular wall 730 is inclined, having a third end 740 located at a high position and a fourth end 750 located at a low position; the bottom shell inside the third annular wall 730 is provided with a second drainage hole 760, and the second drainage hole 760 is opened at the fourth end 750.

[0083] In this embodiment, by tilting the upper surface of the bottom shell 700 inside the third annular wall 730 , water in the isolation chamber 600 flows toward the fourth end 750 and flows out of the shell from the second drainage hole 760 .

[0084] It should be noted that when the socket enters a large amount of water, such as in the extreme case where the socket is immersed in water, the live wire unit 100 and the ground wire unit 300 located in the accommodating cavity 500 and the isolation cavity 600 will still be conducted by the water, causing current to be generated in the ground wire, thereby causing the leakage protection switch to cut off the circuit.

[0085] At this time, after the socket is taken out of the water and the water in the socket flows out through the drain hole, according to the technical effect of setting the drain hole, the remaining water will only adhere to the surface of each component of the socket, and no water will accumulate inside the socket. However, the remaining water may still conduct the ground wire unit 300 and the live wire unit 100. In order to eliminate the tripping caused by this situation as much as possible, the present application proposes another embodiment. In this embodiment, the first end 400a is on the same side as the fourth end 750, and 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, and the path of the water layer conducting the ground wire unit 300 and the live wire unit 100 is long and the resistance is large. Therefore, even if it is conducted, its current is small. In the case of a very thin water layer, the live wire unit 100 and the ground wire unit 300 are conducted so that the current generated in the ground wire is not enough to trigger the leakage protection switch. Therefore, unnecessary tripping can be avoided as much as possible, so that in an emergency, the supply of electricity can still be guaranteed to avoid power outages caused by accidents, but at the same time, electricity is needed to quickly solve the unexpected problem.

[0086] When a plug is inserted into a socket, water is splashed onto the socket. It is not easy for water to enter through the plug-in connection between the plug and the socket. However, the socket usually has multiple socket units for multiple plugs to be inserted into to draw power. When only some of the plugs are inserted into the socket, the water splashed onto the socket is easy to flow into the socket from the socket of the unplugged plug. When it flows to the pins of the plug inserted into the socket, it is easy to cause the live wire pin and the ground wire pin of the plug inserted into the socket to be connected, thereby causing a trip. To avoid unnecessary tripping in this situation, in one embodiment, refer to Figure 1 and Fig.12A shelf 800 is also provided above the partition, and the shelf 800 is provided with holes for the plug pins to pass through. A protective door 802 is provided above the shelf 800; the partition is provided with an upwardly extending convex wall 801 around the hole corresponding to the ground wire, and the ground wire pin is inserted from the convex wall 801.

[0087] The protective door 802 can reduce the amount of water that is splashed onto the socket and enters the socket. The convex wall 801 surrounding the ground wire jack on the shelf 800 can surround the ground wire pin of the plug, so that when there is a small amount of water on the shelf 800, the ground wire pin and the live wire pin will not be connected, and the safety protection switch will not be triggered, thus avoiding unnecessary tripping. In addition, the setting of the shelf 800 allows the water that is splashed onto the socket to enter through the socket jack and flow to the bottom through the jack. There should be a through hole of the partition below the jack, and the water flowing in from the jack will be diverted to the isolation chamber 600 and the accommodating chamber 500. When a small amount of water enters, the metal parts of the isolation chamber 600 and the accommodating chamber 500 will not be turned on, and the ground wire will not generate current due to the accidental water inflow into the socket, thus preventing unnecessary tripping.

[0088] Under normal circumstances, the ground wire is grounded and the voltage to the ground is zero. Although the neutral wire is not grounded, its voltage to the ground is also zero. However, when actually using electricity, there may be some abnormalities, resulting in normal electricity use but the neutral wire's power supply to the ground is not zero. When the voltage of the neutral wire to the ground is not zero, if the neutral wire and the ground wire are conductive, current will be generated in the ground wire, which may cause the leakage protection switch to identify a dangerous leakage situation in the power circuit, causing the leakage protection switch to trip. When the voltage of the neutral wire to the ground is not zero, the value of its voltage to the ground is usually very small. If the ground wire and the neutral wire are connected by water at this time, the current generated in the ground wire is too small to cause the leakage protection switch to cut off the circuit. However, when the socket is actually accidentally splashed with liquid, usually tap water, rain water, tea, wine, soup, etc., there are ions in the soup that enhance the conductivity of the liquid. Therefore, when the socket is accidentally splashed with soup, if the voltage of the neutral wire to the ground is not zero, it may cause a relatively large current to be generated in the ground wire, causing the leakage protection switch to cut off the circuit, resulting in unnecessary tripping.

[0089] In order to solve the problem of unnecessary tripping caused by this incidental factor, based on the above-mentioned embodiment, the utility model also proposes an embodiment that can further prevent unnecessary tripping, please refer to Fig.18 and Fig.19 .

[0090] In this embodiment, a dividing weir 900 is further provided in the accommodating chamber 500. When the ground wire unit 300 is located in the accommodating chamber 500 and the live wire extension portion 120 is located in the isolation chamber 600, the neutral wire unit 200 or the ground wire unit 300 is located in the dividing weir 900. The liquid entering the socket corresponding to the dividing weir 900 and the liquid entering from other sockets of the socket are divided by the dividing weir 900 and cannot be connected, so that when the socket is accidentally splashed with a highly conductive liquid, the liquid can conduct the neutral wire unit and the ground wire unit in the accommodating chamber, thereby avoiding unnecessary tripping caused by this.

[0091] In addition, when the live wire unit 100 is located in the accommodating chamber 500 and the ground wire extension portion 320 is located in the isolating chamber 600, the neutral wire unit 200 or the live wire unit 100 is located in the dividing weir 900. The liquid entering the socket corresponding to the dividing weir and the liquid entering from other sockets of the socket are separated by the dividing weir 900 and cannot be connected, which can prevent the liquid from conducting the live wire and the neutral wire in the accommodating chamber when the socket is accidentally splashed with a highly conductive liquid, thereby preventing the live wire and the neutral wire in the socket from short-circuiting and overheating.

[0092] In addition to using the dividing dam 900 to divide the accommodating chamber, a cofferdam 901 can also be used. When the live wire extension part 120 is located in the isolation chamber 600 and the neutral wire unit 200 and the ground wire unit 300 are located in the accommodating chamber 500, the neutral wire plug-in part 210 or the ground wire plug-in part 310 in the accommodating chamber 500 is separated separately, which can prevent the neutral wire and the ground wire from being conductive. In actual use scenarios, when the socket is splashed with a highly conductive liquid, the amount of liquid that can enter the socket is very small. The cofferdam 901 is used to separate the ground wire plug-in part or the neutral wire plug-in part, so that the liquid entering from the ground wire jack or the neutral wire jack is blocked by the cofferdam and will not flow to other parts inside the socket. The space inside the socket is large, and the liquid that can enter from the jack usually cannot connect the ground wire extension part and the neutral wire extension part. Therefore, the cofferdam 901 is set in the accommodating cavity 500 to prevent the socket from accidentally entering a highly conductive liquid to connect the neutral wire and the ground wire, causing the ground wire to generate current and causing the leakage protection switch to cut off the current. Similarly, when the ground wire extension part is located in the isolation cavity and the live wire unit and the neutral wire unit are located in the accommodating cavity, it can also be prevented that the live wire and the neutral wire in the socket are short-circuited and overheated when the socket is accidentally splashed with a highly conductive liquid.
