Description

Technical Field

[0001] The utility model belongs to the field of leakage prevention safety, and particularly relates to the field of leakage prevention plug boards. Background Art

[0002] The current devices for taking or connecting electricity can only be used safely and normally in a dry environment. However, when faced with accidental immersion in water, water spraying, water splashing, moisture or intrusion of other conductive liquids, it is easy to leak electricity to the outside of the device through the charged liquid immersed in the device, or the conductive metal parts inside the device are oxidized and electrolyzed, resulting in poor contact and abnormal temperature rise, so there is a very high risk of leakage and electric shock. In addition, the existing physical waterproof devices on the market have not completely solved this problem from the root or technical end, and can only solve the problem of device water prevention or water splashing. If the physical waterproof structure is used for a long time, or the load connected to the device is fully loaded, it is easy to expand and contract due to heat and cold, resulting in aging of the closed structure or loss of sealing function. In addition, the plug hole of the physical waterproof device cannot be sealed because it needs to connect to the load device. As long as the live wire plug hole of the physical waterproof device is soaked in water, it will cause the device to be soaked in water. The metal parts connected to the live wire in the device will come into contact with water, resulting in leakage or voltage and current spreading outward through water as a conductor, which is very likely to cause serious damage to the user's life and property safety.

A protrusion 3-3 corresponding to at least the position of the live line socket 1-1 and the neutral line socket 1-2 is provided on the protective device 3, and the protrusion 3-3 runs through from top to bottom. Specifically, the protrusion 3-3 is a tubular structure that runs through from top to bottom. When installed, the protrusion 3-3 is set downward, and the inner core body 1 is located below the protective device 3. After the protective device 3 is installed, the neutral wire socket 1-2 and the live wire socket 1-1 are respectively placed in the inner cavity enclosed by the inner wall of the protrusion 3-3; when the live wire terminal is plugged into the live wire socket 1-1, at least the broken line distance value between the outer side surface of the protrusion 3-3 and the center plane of the live wire terminal is greater than or equal to 3mm; similarly, the broken line distance value between the outer side surface of the protrusion 3-3 corresponding to the socket for plugging the neutral wire terminal and the center plane of the neutral wire terminal is greater than or equal to 3mm, and the broken line distance value is: the sum of the distance value between the inner surface of the protrusion and the center plane of the live wire terminal, the height value of the protrusion, and the thickness value of the protrusion, such as Figure 4 In the enlarged view B, the height value of the protrusion is a, the thickness value of the protrusion 3-3 is b, and the distance value between the inner surface of the protrusion 3-3 and the center plane of the live wire terminal is c. Therefore, the sum of the distance values ​​between the inner surface of the protrusion 3-3 and the center plane of the live wire terminal is the sum of a, b, and c, that is, a+b+c is greater than or equal to 3 mm.

[0039] In some feasible implementations, because the ground wire serves as a safety circuit for electricity use, a ground wire socket 1-3 can also be provided on the inner core body 1, and the ground wire socket 1-3 is connected to the ground wire, and the ground wire socket 1-3 is used to plug in the ground wire terminal; accordingly, a protrusion 3-3 corresponding to the position of the ground wire socket 1-3 is also provided on the protective device 3, and the protrusion 3-3 is a tubular structure running through from top to bottom.

The protrusion 3-3 is arranged on the upper surface of the support base 3-2, and penetrates up and down to the concave surface 3-5 of the protective device 3 at the protrusion 3-3. When the protective device 3 is installed, the protrusion 3-3 faces downward and the support base 3-2 faces upward. When water or other conductive liquids enter the leakage protection device, the concave surface 3-5 of the protective device 3 can accommodate more conductive liquids.

[0041] In some feasible implementations, a conductive connector 2-11 is provided on the conductor 2, and the conductive connector 2-11 can increase the area of ​​the conductor 2, thereby increasing the contact area between the conductor 2 and the conductive liquid. Fig. 9 In some feasible implementations, the conductive connector 2-11 may be on the same plane as the conductor 2; see Figure 8 In other feasible implementations, the conductive connector 2-11 can be located on the side of the conductor 2, and the conductive connector 2-11 can be perpendicular or non-perpendicular to the conductor 2. The length of the conductive connector 2-11 is adaptively designed according to the number of conductors 2 that need to be connected in the horizontal direction. The conductor 2 can be one or several anti-leakage protection devices integrated into one; the length of the corresponding conductive connector 2-11 can be equal to the sum of the lengths of several conductors 2 plus the gaps of the conductors 2 in the horizontal direction. Several conductors 2 are connected together in the horizontal direction through the conductive connector 2-11. After several conductors 2 with conductive connectors 2-11 are installed with a corresponding number of inner core bodies 1, multiple plug-in requirements can be met, and at the same time, the contact area between the conductor 2 and the conductive liquid is increased, so that the charged liquid immersed in the plug board can fully or more contact the conductor 2 to do work, thereby consuming the charge in the charged water or lowering the potential difference of the charged liquid.

[0042] In some feasible embodiments, the conductor 2 includes a first conductor 2-1, which is a flat plate. The first conductor 2-1 is provided with a relief opening 3-1, and the relief opening 3-1 corresponds to the position of the socket. The socket is used to plug in the live wire terminal or the neutral wire terminal. The socket connected to the neutral wire is the neutral wire socket 1-2, and the socket connected to the live wire is the live wire socket 1-1. The relief opening 3-1 corresponds to the positions of the neutral wire socket 1-2 and the live wire socket 1-1 respectively; the conductor 2 is placed above the protective device 3, and the relief opening 3-1 corresponds to the position of the protrusion 3-3. Furthermore, the straight-line distance between the inner side surface of the relief opening 3-1 on the first conductor 2-1 and the center plane of the socket is greater than or equal to 3 mm, such as Figure 1 In the enlarged view A, the straight-line distance between the inner side surface of the avoidance opening 3-1 on the first conductor 2-1 and the center of the socket is d, that is, d is greater than or equal to 3 mm.

[0043] In some other feasible implementations, the leakage prevention device of the present application includes a first conductor 2-1 and a second conductor 2-2. Both the second conductor 2-2 and the first conductor 2-1 are flat plates. Both the second conductor 2-2 and the first conductor 2-1 have avoidance openings 3-1, and the avoidance openings 3-1 correspond to the positions of the sockets. The sockets are used to plug in the live wire terminal or the neutral wire terminal. The socket connected to the neutral wire is the neutral wire socket 1-2, and the socket connected to the live wire is the live wire socket 1-1. The avoidance openings 3-1 correspond to the positions of the neutral wire socket 1-2 and the live wire socket 1-1, respectively. Specifically, during installation, the protrusion 3-3 of the protective device 3 faces downward, the avoidance opening 3-1 of the second conductor 2-2 is installed on the protrusion 3-3 of the protective device 3, the first conductor 2-1 is placed above the protective device 3, and the avoidance opening 3-1 on the first conductor 2-1 corresponds to the position of the protrusion 3-3. See. Figures 10 to 12 In the present application, the second conductor 2-2 and the first conductor 2-1 may be of the same shape and size, or of different shapes and sizes. For example, if the leakage prevention device needs to be plugged with a plurality of three-pin plugs and a plurality of two-pin plugs, the arrangement of the sockets is a row of sockets for plugging three-pin plugs, and a row parallel to the row of sockets for plugging two-pin plugs. The second conductor 2-2 or the first conductor 2-1 may be designed as a flat plate including a avoidance port 3-1 that only cooperates with the live wire socket 1-1 that is only plugged with the three-pin plug and the two-pin plug, see Fig.12 The second conductor 2-2 or the first conductor 2-1 can also be designed as a flat plate with a relief port 3-1 that cooperates with the live wire interface, the neutral wire interface, and the ground wire interface of a three-pin plug and a two-pin plug, see Fig.10Of course, multiple layers of conductors 2 provided with avoidance openings 3-1 may be added between the second conductor 2-2 and the first conductor 2-1. The multiple layers of conductors 2 may be parallel or non-parallel. The shape of the multiple layers of conductors 2 may be the same as that of the second conductor 2-2 or the first conductor 2-1, so as to increase the contact area between the conductor 2 and the conductive liquid invading between the second conductor 2-2 and the first conductor 2-1.

[0044] See also Figures 5 to 7 In order to ensure the safety and stability of the anti-leakage device during use, in the present application, the inner core body 1 can be fixed by the installation cavity 4, and the installation cavity 4 includes a socket installation groove 4-2 and a transition groove 4-1, and the inner core body 1 is arranged in the socket installation groove 4-2. In the present application, the socket installation groove 4-2 is designed to be a groove shape that can accommodate the socket, and is arranged according to the angle and number between each socket. Specifically, the socket installation groove 4-2 can be arranged according to the consistency of the angle of the socket. The socket installation groove 4-2 that needs to install several sockets with the same angle can be designed in a row. According to the arrangement of the sockets on the inner core body 1, several rows of socket installation grooves 4-2 that are consistent with the arrangement of the sockets on the inner core body 1 can be set on the installation cavity 4. Furthermore, when there are multiple sockets with the same direction and a certain regular arrangement, a card slot 4-5 can be designed on the installation slot, and the card slot 4-5 is connected to the groove for accommodating the socket, and several regularly arranged sockets are made into one, which can be simultaneously snapped into the socket installation slot 4-2. Furthermore, a leakage hole 4-3 is provided on the transition groove 4-1, and when the conductive liquid invades the anti-leakage protection device of the present application, the conductive liquid can flow out to the outside of the anti-leakage protection device through the leakage hole 4-3. A mounting screw hole 4-4 can also be provided on the installation cavity 4, and the installation cavity 4 is fixed by the mounting screw hole 4-4.

[0045] In the present application, the socket is made of conductive metal. When several regularly arranged sockets are made into an integrated whole, except for the socket part used to plug into external conductive terminals such as the live terminal or the neutral terminal, the rest of the conductive metal part is useless and exposed. When the installation cavity 4 is invaded by a conductive liquid, the risk of conduction is increased. Therefore, in some feasible implementations, when the socket is installed in the socket installation groove 4-2, the rest of the space in the socket installation groove 4-2 except the socket is filled with sealant 4-6, which can reduce the contact area between the conductive metal and the conductive liquid and reduce the risk of conduction. The anti-leakage protection device of the present application involves the safety of electrical appliances. Therefore, the sealant 4-6 can be made of silicone or epoxy resin potting glue to seal the rest of the space in the socket installation groove 4-2 except the socket. Flame-retardant sealant can also be selected, such as flame-retardant silicone or flame-retardant epoxy resin potting glue with flame-retardant properties, which not only has a sealing effect, but also has a flame-retardant effect.

[0046] The leakage protection device of the present application also includes a shell, which is composed of an upper cover 6 and a base 5. The upper surface of the upper cover 6 is provided with a plug hole 6-4, and the plug hole 6-4 corresponds to the position of the socket. Specifically, during installation, the inner core body 1 is installed in the socket installation groove 4-2 of the installation cavity 4, the socket is located in the groove of the socket installation groove 4-2, and the installation cavity 4 is set and fixed in the space formed inside the shell. Furthermore, in order to prevent the installation cavity 4 from shaking during use, a fixing screw hole 5-1 for fixing the installation cavity 4 can be provided on the upper cover 6, and the installation screw hole 4-4 is aligned with the fixing screw hole 5-1, and the installation cavity 4 is fixed to the upper cover 6 by the cooperation of the screw and the screw hole. In some optional embodiments, the first conductor 2-1 can be fixed on the inner surface of the upper cover 6 during installation, the avoidance opening 3-1 corresponds to the position of the plug hole 6-4, and is fixed on the upper cover 6 through the installation cavity 4. At the same time, the first conductor 2-1 can be placed above the protective device 3 and fit the upper cover 6. After the installation cavity 4 and the upper cover 6 are fastened, the installation position of the first conductor 2-1 is also relatively fixed. In the present application, the conductor 2 can also be directly placed on the inner wall of the upper cover 6 of the plug board in a semi-enclosed form. Specifically during installation, the inner core body 1 can be placed in the installation cavity 4 first, and then the second conductor 2-2 can be attached to the protective device 3, the avoidance opening 3-1 on the second conductor 2-2 corresponds to the protrusion 3-3 on the protective device 3, the protective device 3 can be turned upside down with the protrusion 3-3 facing downward, and then the fixing ear 3-4 can be aligned with the installation screw hole 4-4, and the protective device 3 can be fixed on the installation cavity 4, and then the first conductor 2-1 can be placed above the protective device 3 and attached to the upper cover 6, the installation screw hole 4-4 can be aligned with the fixing screw hole 5-1, and then the installation cavity 4 can be fixed on the upper cover 6.

[0047] See also Fig.14 , there are a first socket area 6-2 and a second socket area 6-1 on the upper cover 6, the first socket area 6-2 corresponds to an external two-pin plug, and the second socket area 6-1 corresponds to an external three-pin plug. Correspondingly, on the inner core body 1, the first socket area 6-2 is provided with a neutral line socket 1-2, a live line socket 1-1 and a ground line socket 1-3, and the second socket area 6-1 is provided with a neutral line socket 1-2 and a live line socket 1-1; several first socket areas 6-2 and several first socket areas 6-2 are regularly arranged in the horizontal direction, and several rows of socket installation grooves 4-2 consistent with the socket arrangement on the inner core body 1 can be provided on the installation cavity 4. The first socket area 6-2 can be used to plug in a three-pin plug, and the second socket area 6-1 can be used to plug in a two-pin plug.

[0048] In the present application, the socket is connected to an external power cord, a clip 5-2 for fixing the power cord is provided on the base 5, one end of the power cord is fixed on the housing, and then extends into the installation cavity 4 and is connected to the socket. In some feasible implementations, a switch button 6-3 may also be provided on the housing, a switch assembly 7 may also be installed on the base 5, the switch button 6-3 extends into the installation cavity 4, and the power cord is connected to the socket through the switch assembly 7.

[0049] In the present application, since the sockets for connecting the live wire, the neutral wire, and the ground wire in the leakage protection device are fixed on the installation cavity 4 and are surrounded by the plug board shell on all sides, after the live wire terminal or the neutral wire terminal is connected, the leakage protection device is connected to the power supply. Therefore, after the leakage protection device invades the conductive liquid, when the conductive liquid flows through the live wire terminal, it becomes a charged liquid. The only way for the charged liquid to conduct voltage outside the leakage protection device is through the plug hole 6-4 of the upper cover 6 of the shell. Furthermore, the surface of the conductor 2 of the present application is treated with inertness, such as nickel plating, to avoid the risk of poor contact caused by electrolysis or oxidation of the conductor 2 when it interacts with the charged liquid after being immersed in the conductive liquid. The inert treatment of the conductor 2 can extend the safe use and life of the plug board.

[0050] When the conductive liquid intrudes into the leakage prevention device of the present application, the conductive body 2 divides the conductive liquid in the leakage prevention device into two parts, and the two conductive surfaces can fully contact and work with the divided upper and lower parts of the charged liquid, consuming the voltage of the charged liquid to lower the potential difference of the charged liquid. In this case, only a small amount of charged liquid will conduct current and voltage from the avoidance port 3-1 of the conductive body 2 to the upper space area of ​​the leakage prevention device.

[0051] When the second conductor 2-2 is installed at the protrusion 3-3 of the protective device 3, after the conductive liquid passes through the second conductor 2-2 to lower the potential difference of the charged liquid, the conductive liquid flows into the upper space area of ​​the anti-leakage device from the protrusion 3-3 that penetrates from top to bottom on the protective device 3 to conduct current and voltage. In this process, the charged liquid is prevented from conducting current and voltage to the external water area in a straight line through the plug hole 6-4 of the shell of the anti-leakage device, and the residual charged water flowing out from the avoidance 3-1 of the second conductor 2-2 to the plug hole of the plug board shell can be dispersed and flow through the first conductor 2-1 set there. In addition, the space occupied by the protective device 3 is used to squeeze the water content inside the plug board, reducing the volume and charge of the charged liquid, so that the charged liquid flowing into the upper space area, that is, between the protective device 3 and the first conductor 2-1, can fully contact with the first conductor 2-1 and do work. The first conductor 2-1 again works with the residual charged liquid flowing out from the protrusion 3-3 matched with the second conductor 2-2, further consuming and lowering the current and voltage of the charged liquid, and finally reaching a voltage of less than 36V transmitted to the external conductive liquid area through the shell jack of the leakage protection device. In actual testing, the voltage of the external conductive liquid area of ​​the leakage protection device of this application is less than 25V. The ground terminal inside the leakage protection device detects that the current of the charged liquid after the leakage protection device is immersed in the conductive liquid is less than 10 mA, which is lower than the current standard of the leakage protection leakage brake, which fully ensures that the load connected to the leakage protection device for power supply works normally after the leakage protection device is immersed in the conductive liquid.

[0052] In the present application, the conductor 2 can be made of copper sheet or aluminum sheet, or can be made of other conductive materials.

[0053] It should be noted that the conductive liquid mentioned in the present application can be ordinary domestic water, or other non-corrosive conductive liquids. The leakage protection device of the present application cannot be immersed in sewage, salt water, carbonic acid and corrosive liquids.

[0054] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
