[0001] The invention relates to the technical field of safety sockets, in particular to a high-safety socket. Background Art

[0002] As an indispensable product in urban construction and family life, sockets have a wide range of applications. In family life, sockets are necessary tools for connecting devices. In order to facilitate connection, some sockets in the home are installed at a lower position. Although this installation is more convenient for connecting some specific devices, it undoubtedly increases the risk of young children easily plugging in by mistake. The socket's anti-mis-touch technology for young children has always been the top priority of socket innovation.

[0003] Existing two-hole sockets generally have a simple safety door, that is, an insulating plastic block cooperates with a spring to block the socket. The protection effect of the safety door is directly related to the elasticity of the spring. The spring elasticity decreases during long-term use and the safety door will fail, resulting in poor protection. At the same time, relying solely on springs and insulating blocks cannot completely prevent children from inserting foreign objects with their fingers or hands. If the object is inserted forcefully, the safety door will still be pushed open, causing a risk of electric shock. Summary of the invention

[0020] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0021] See also Figure 1-Figure 9 A high-safety socket comprises a plug board 1, a switch button 101 is arranged on the plug board 1, and a plug hole 102 is opened. A mounting plate 2 is installed on one side of the plug board 1, and a switch junction box 201 and a plug junction box 202 for connecting wires are installed on the side of the mounting plate 2 opposite to the plug board 1. A switch trigger 203 electrically connected to the switch junction box 201 is installed on the side of the mounting plate 2 opposite to the plug board 1. A first barrier mechanism 3 for preventing children from inserting by mistake and a second barrier mechanism 4 for further improving the barrier effect when foreign objects are inserted, as well as a self-inspection mechanism for performing safety self-inspection on the first barrier mechanism 3 are installed on the side of the mounting plate 2 opposite to the plug board 1. Mechanism 5 forms the first protection for the socket 102 through the first barrier mechanism 3. The second barrier mechanism 4 further improves the safety and forms the second protection on the basis of the first barrier mechanism 3. Through the two protections, it is strictly stipulated that the plug can be successfully connected only when the two holes of the socket 102 are inserted at the same time. Even if a part of the first barrier mechanism 3 fails, the setting of the second barrier mechanism 4 will make up for the deficiency of the first barrier mechanism 3 and still form a sealing effect on the socket 102. The first barrier mechanism 3 is monitored in real time through the self-checking mechanism 5. When the first barrier mechanism 3 fails, the signal is fed back in time to achieve the self-checking effect.

[0022] Furthermore, the first blocking mechanism 3 includes a rectangular frame 301, which is fixedly connected to one side of the mounting plate 2 opposite to the plug plate 1, and first sliding grooves 302 are provided on the left and right sides of the inner wall of the rectangular frame 301, and second sliding blocks 311 are slidably connected in the two first sliding grooves 302, and second limiting grooves 310 are provided on the two second sliding blocks 311, and third limiting grooves 314 adapted to the second limiting grooves 310 are provided near the top of the two first sliding grooves 302, and a clamping block 308 adapted to the third limiting groove 314 is slidably connected in the second limiting groove 310, and two ends of the clamping block 308 are respectively located in the third limiting groove 314 and the second limiting groove 310, and the clamping block 308 and the second limiting groove 310 are connected together. A first spring 309 is fixedly connected, and a first baffle block 303 is fixedly connected to the opposite side of the two second sliding blocks 311. Two sliding cavities 304 corresponding to the jack 102 are provided on the side of the first baffle block 303 opposite to the plug board 1. The first sliding blocks 305 are slidably connected in the two sliding cavities 304. The first limiting groove 306 is provided on the side of the two sliding cavities 304 close to the adjacent first sliding groove 302. A first connecting block 307 is slidably connected in the first limiting groove 306. The two ends of the first connecting block 307 are respectively fixedly connected to the adjacent first sliding block 305 and the clamping block 308. A second spring 312 is fixedly connected between the bottom of the first baffle block 303 and the inner wall of the rectangular frame 301. First, the plug When the first and second locking assemblies 306 are in the process of being inserted into the socket 102, the plug will preferentially abut the first sliding block 305, and in the process of continuous pushing, the first sliding block 305 will be pushed to move into the sliding cavity 304. During this process, the movement of the first sliding block 305 will drive the clamping block 308 to move synchronously through the first connecting block 307, so that one end of the clamping block 308 gradually leaves the third limiting groove 314 and completely returns to the second limiting groove 310. At this time, the first spring 309 is compressed by the clamping block 308. When the two ends of the clamping block 308 no longer form a clamping effect on the second limiting groove 310 and the third limiting groove 314, the second sliding block 311 will carry the clamping block 308 and move downward under the continuous abutment and pushing of the plug, so as to facilitate the further entry of the plug and the internal plug. The first blocking block 303 is connected to the head connection port. The above arrangement, by respectively arranging relevant clamping parts such as clamping blocks 308 at both ends of the first blocking block 303, can achieve the goal that only when the two holes of the jack 102 are inserted at the same time can the first blocking block 303 be pushed down. When only one hole of the jack 102 is inserted, the first blocking block 303 cannot be pushed down, and the plug cannot be smoothly connected to the internal plug connection hole. Therefore, when a young child inserts a finger or a foreign object into a hole in the jack 102 alone, a blocking effect can be achieved to prevent direct electric shock, thereby achieving a protective effect. The multi-structure arrangement of the first sliding block 305, the clamping block 308 and the first spring 309 also greatly enhances the damping force and reduces the possibility of successful insertion of children.

[0023] Further, the second blocking mechanism 4 includes a second connecting block 401, which is fixedly connected to the first sliding block 305 located on the left, and penetrates the connecting sliding cavity 304. The mounting plate 2 is provided with two second sliding grooves 405 on one side relative to the plug plate 1, and the two second sliding grooves 405 correspond to the two first sliding blocks 305, respectively. The second blocking block 404 is slidably connected in the two second sliding grooves 405, and the second blocking block 404 and the bottom of the inner wall of the rectangular frame 301 are fixedly connected with a fourth spring 406. When the first sliding block 305 on the left side is pushed by the plug, the first sliding block 305 on the left side starts to move toward the sliding cavity 304, and pushes the second connecting block 401 to continue to penetrate the sliding cavity 304 and extend to the top of the bottom of the second blocking block 404. As the first sliding block 305 on the left side moves to the end point, the clamping block 308 leaves the third limiting groove 314. Under the continuous push of the plug, the first blocking block 303 starts to descend. At this time, the end of the second connecting block 401 extending to the top of the bottom of the second blocking block 404 The second blocking block 404 will be pressed down, so that it will follow the first blocking block 303 to synchronously descend, and finally both plug connection holes will be fully exposed, which is convenient for plug insertion. Among them, when the first spring 309 on the left side of the first blocking mechanism 3 fails, it is assumed that the left clamping block 308 loses the effect of clamping the corresponding second limiting groove 310 and the third limiting groove 314, and only the right first sliding block 305 is pushed into the sliding cavity 304. Although the first blocking block 303 can be pushed down at this time, due to the lack of directional force abutting the left first sliding block 305, the left second connecting block 401 cannot extend to the top of the bottom of the second blocking block 404, and it is also impossible to drive the second blocking block 404 to synchronously descend. The second blocking block 404 will still block foreign objects and children's fingers that are mistakenly inserted into the right connecting hole, avoiding the risk of direct exposure of the connecting hole after the first blocking mechanism 3 fails, and forming a double-layer protection setting with the first blocking mechanism 3 to avoid the risk of entry of young children or foreign objects to the greatest extent, thereby enhancing the safety of the socket.

[0024] It is worth noting that according to the normal wiring principle of left neutral and right live, when the socket itself and the line itself have no other hidden dangers such as short circuit and leakage, the left connecting hole is in a no-power state. Even if the first blocking mechanism 3 fails and causes children to mistakenly plug the neutral wire into the connecting hole, there is no electric shock problem. The setting of the second blocking mechanism 4 makes it impossible for the operator to synchronously drive the second blocking block to follow the first blocking block 303 to descend when the first sliding block 305 pushes the second connecting block to extend above the bottom of the second blocking block 404 without abutting the left first sliding block 305, and exposes the electric connecting hole on the right side of the live wire, so that the live wire connecting hole can only be opened when the two connecting holes are inserted at the same time, thereby preventing children from accidentally inserting into the live connecting hole and causing electric shock to the greatest extent.

[0025] Further, the self-test mechanism 5 includes two LED lamps 501, and the two LED lamps 501 are respectively embedded on the outer surface of the plugboard 1. Two circuit connectors 502 connected to the third limiting grooves 314 are embedded and installed near the two third limiting grooves 314 of the rectangular frame 301, and the two circuit connectors 502 are distributed up and down. A circuit connection shaft 503 adapted to the circuit connector 502 is embedded and installed in the clamping block 308. The circuit connector 502 is electrically connected to the corresponding LED lamp 501. In the initial state, the clamping block 308 is pushed into the third limiting groove 314 by the elasticity of the first spring 309. At this time, the circuit in the clamping block 308 The connecting shaft 503 will connect the upper and lower circuit connectors 502, so that the circuits of the two circuit connectors 502 are connected, and the LED light 501 is lit. On the contrary, when the socket is successfully inserted, the snap-in block 308 retracts into the second limit groove 310, and as the second sliding block 311 descends and leaves the third limit groove 314, the LED light 501 will go out. By observing the lighting of the LED light 501 and whether the plug is inserted into the socket, it is possible to determine whether the parts at the snap-in block 308 are normal, thereby achieving a self-inspection effect on the first barrier mechanism 3, thereby avoiding the problem that the failure of the first barrier mechanism 3 cannot be detected, resulting in reduced protection, and thus easily causing safety hazards.

[0026] Furthermore, both ends of the second spring 312 are sleeved with limit shafts 313, and the two limit shafts 313 are respectively fixedly connected to the bottom of the inner wall of the rectangular frame 301 and the bottom of the first sliding block 305. Through this arrangement, the two ends of the second spring 312 can be limited, avoiding the problem of the end of the second spring 312 falling off and shifting during long-term compression movement, thereby improving the service life of related components.

[0027] Furthermore, a third spring 402 is fixedly connected between the inner wall of the sliding cavity 304 and the first sliding block 305. Through the setting of the third spring 402, on the one hand, the resetting effect of the first sliding block 305 can be enhanced, and at the same time, the first sliding block 305 can be buffered during the extrusion movement, thereby reducing the pressure of the first spring 309 and extending the service life of the first spring 309.

[0028] Furthermore, a limit block 403 is provided inside one end of the third spring 402 close to the sliding cavity 304, and the limit block 403 is fixedly connected to the inner wall of the sliding cavity 304. Through the setting of the limit block 403, the end point of the moving first sliding block 305 can be limited, so that the top of the first sliding block 305 after moving to the end point is matched with the top of the first blocking block 303, avoiding the problem of the plug being stuck in the sliding cavity 304 and being unable to be inserted smoothly, and also avoiding damage caused by excessive compression of the third spring 402.

[0029] Furthermore, the first sliding block 305 and the first blocking block 303 are respectively arranged as an inclined surface and an arc-shaped surface on one side relative to the insertion hole 102. Through the above arrangement, it is possible to provide damping while facilitating the insertion of the plug, thereby achieving the effect of squeezing the first sliding block 305 to move into the sliding cavity 304, and the first blocking block 303 to move downward in the first sliding groove 302, and finally smoothly inserting it into the designated position.

[0030] Furthermore, the contact surface size of the two circuit connecting heads 502 is larger than the contact surface size at both ends of the circuit connecting shaft 503. Through this setting, it can be ensured that after the clamping block 308 is inserted into the third limiting groove 314, the circuit connecting shaft 503 and the two upper and lower circuit connecting heads 502 are smoothly connected, so that the LED lamp 501 lights up and achieves a self-test effect.

[0031] Furthermore, the second blocking block 404 is in an L-shape, and the lower surface of the second connecting block 401 is higher than the upper surface of the L-shaped bottom of the second blocking block 404. Through this arrangement, when the first sliding block 305 moves, the second connecting block 401 can be extended and located above the bottom of the second blocking block 404. At this time, when the first blocking block 303 descends, it will drive the second blocking block 404 to move downward and smoothly expose the internal plug connection hole. The working principle of the method of use of the present invention is as follows: first, insert the plug into the socket 102, then the plug will preferentially abut the first sliding block 305, and in the process of continuous pushing, push the first sliding block 305 to move into the sliding cavity 304. During this process, the movement of the first sliding block 305 will drive the clamping block 308 to move synchronously through the first connecting block 307, so that one end of the clamping block 308 gradually leaves the third limiting groove 314 and completely returns to the second limiting groove 310. At this time, the first spring 309 is compressed by the clamping block 308. When the two ends of the clamping block 308 no longer form a clamping effect on the second limiting groove 310 and the third limiting groove 314, the second sliding block 311 will carry the clamping block 308 and move downward under the continuous abutment and push of the plug, which is convenient for The plug is further inserted and connected with the internal plug connection port. The above arrangement, by respectively arranging relevant clamping parts such as clamping blocks 308 at both ends of the first blocking block 303, can achieve the goal that only when the two holes of the jack 102 are inserted at the same time can the first blocking block 303 be pushed down, and when only one hole of the jack 102 is inserted, the first blocking block 303 cannot be pushed down, and the plug cannot be smoothly connected with the internal plug connection hole, so that when a young child inserts a finger or a foreign object into a hole in the jack 102 alone, a blocking effect can be achieved to prevent direct electric shock, thereby achieving a protective effect. The multi-structural arrangement of the first sliding block 305, the clamping block 308 and the first spring 309 also greatly improves the damping force and reduces the risk of children slipping into the socket 102. When the first sliding block 305 on the left side is pushed by the plug, the first sliding block 305 on the left side starts to move toward the sliding cavity 304, and pushes the second connecting block 401 to continue to penetrate the sliding cavity 304 and extend to the top of the bottom of the second blocking block 404. As the first sliding block 305 on the left side moves to the end point, the engaging block 308 leaves the third limiting groove 314. Under the continuous abutment and push of the plug, the first blocking block 303 starts to descend. At this time, the end of the second connecting block 401 extending to the top of the bottom of the second blocking block 404 presses down the second blocking block 404, so that it follows the first blocking block 303 to descend synchronously, and finally exposes all the two plug connection holes, which is convenient for plug insertion. When the first spring 309 on the left side fails, it is assumed that the left-side clamping block 308 loses the effect of clamping the corresponding second limiting groove 310 and the third limiting groove 314, and only the right-side first sliding block 305 is pushed into the sliding cavity 304. Although the first blocking block 303 can be pushed down at this time, due to the lack of directional force abutting the left-side first sliding block 305, the left-side second connecting block 401 cannot extend to the top of the bottom of the second blocking block 404, and cannot drive the second blocking block 404 to descend synchronously. The second blocking block 404 will still block foreign objects and children's fingers that are mistakenly inserted into the right-side connecting hole, avoiding the risk of direct exposure of the connecting hole after the first blocking mechanism 3 fails, and cooperates with the first blocking mechanism 3 to form a double-layer protection setting.The risk of young children or foreign objects entering the socket is avoided to the greatest extent, and the safety of the socket is enhanced. In addition, in the initial state, the clamping block 308 is pushed into the third limiting groove 314 by the elasticity of the first spring 309. At this time, the circuit connection shaft 503 in the clamping block 308 will connect the upper and lower circuit connectors 502, so that the two circuit connectors 502 are connected. At this time, the LED light 501 is lit. On the contrary, when the socket is successfully inserted, the clamping block 308 retracts into the second limiting groove 310, and as the second sliding block 311 descends and leaves the third limiting groove 314, the LED light 501 will go out. By observing the lighting of the LED light 501 and whether the plug is inserted into the socket, it can be judged whether the parts at the clamping block 308 are normal, so as to achieve the self-inspection effect of the first barrier mechanism 3, and avoid the problem that the failure of the first barrier mechanism 3 cannot be detected, resulting in reduced protection, and then easily causing safety hazards.
