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

[0002] Sockets, also known as power sockets and switch sockets, are used to receive electricity from the power supply and supply power to other electrical devices through plugs. According to different functional characteristics, sockets can be divided into ordinary sockets, waterproof sockets, sockets with switches, smart sockets, etc. The switch of a socket with a switch is generally external, and the socket is powered on or off by a button, which still poses a safety hazard of children accidentally touching it.

[0003] A Chinese patent with announcement number CN218300479U discloses a socket with a built-in switch, which includes an isolation component and a switch component. The isolation component includes a base, a protective plate and a pushing structure. The pushing structure is used to push the protective plate to move. A guide structure is provided on one side of the protective plate. An electric contact is provided in the base. The switch component includes a trigger structure and a reset structure. A moving contact is provided on the trigger structure. The reset structure and a static contact are fixedly connected to the fixed base.

[0004] The switch of the above socket is built-in. When the plug is inserted into the socket, the plug contacts the electric contact piece, and the plug squeezes the trigger structure, which in turn drives the moving contact piece to contact the static contact piece, so that the current loop in the socket is connected. The above socket can realize the function that only when the plug is inserted into the socket, the current will flow through the socket, effectively reducing the safety hazard of children accidentally touching it.

[0005] However, the button may not bounce back smoothly during use, and the button is built-in, which is not convenient for manual assistance to push out. Summary of the invention

The baffle 3 is snapped into the inside of the base 1 to play a supporting and separating role. Two springs 4 are provided and are located on the side of the baffle 3 away from the panel 2. The springs 4 are provided for the plug to be inserted and clamped. The grounding plate 5 is arranged inside the base 1 and its two ends are passed through the baffle 3 and the panel 2. The switch mechanism 6 is installed inside the base 1 to connect the circuit when the plug is inserted. The protection mechanism 7 is arranged between the baffle 3 and the panel 2 to prevent children from accidentally touching it.

[0035] Reference Figure 2 , Figure 3 The base 1 is fixedly connected with four hooks 11, and the corners of the baffle 3 are provided with slots 33 for the hooks 11 to hook, so that the baffle 3 is fixed relative to the base 1 and is easy to assemble.

[0036] Reference Figure 6 The switch mechanism 6 includes a button 61 slidably inserted through the baffle 3 and the panel 2, a connection seat 62 engaged with the button 61, a moving contact piece 63 plugged into the connection seat 62, a stationary contact piece 64 plugged into the base 1, and a return spring 65 disposed between the button 61 and the base 1. When the button 61 is pressed by the plug, the connection seat 62 moves downward, so that the moving contact piece 63 contacts the stationary contact piece 64, thereby connecting the circuit.

[0037] Reference Figure 4 , Figure 7 The button 61 includes a pressing rod 613, which is slidably inserted into the baffle 3 and the panel 2. The lower end of the pressing rod 613 is fixedly connected to a pressing seat 614, and both sides of the pressing seat 614 are fixedly connected to a clamping block 615. The lower side of the pressing seat 614 is fixedly connected to a limiting rod 616, and the limiting rod 616 is inserted into the reset spring 65 to achieve positioning. The pressing seat 614 is inserted into the connecting seat 62, and the connecting seat 62 is provided with a clamping hole 621 for the clamping block 615 to be inserted, so that the button 61 and the connecting seat 62 are relatively fixed. The moving contact piece 63 is U-shaped and the middle part is clamped between the pressing seat 614 and the connecting seat 62. A limiting hole 622 for the reset spring 65 to pass through is provided in the middle of the connecting seat 62. The reset spring 65 is subject to a good limiting effect to ensure that the position is not easily deviated, thereby ensuring that the button 61 rebounds smoothly.

[0038] Reference Figure 5 , Figure 6The protection mechanism 7 includes a protection door 71 disposed between the baffle 3 and the panel 2. The protection door 71 is slidably connected to the baffle 3. A protection spring 72 is disposed between the protection door 71 and the panel 2. The protection spring 72 is used to apply a thrust to the protection door 71, so that a certain force is required to squeeze the protection door 71 open. The protection door 71 includes two protection parts 711 and a connecting part 712 fixedly connected between the two protection parts 711. A U-shaped groove is formed between the protection part 711 and the connecting part 712. A convex seat 32 inserted into the U-shaped groove is formed in the middle of the baffle 3. The convex seat 32 is used to block the connecting part 712 to limit the position of the protection door 71.

[0039] The baffle plate 3 is provided with a through hole 31 for the plug to be inserted, one side of the through hole 31 is opposite to the spring sheet 4, and the other side is opposite to the protection part 711. The protection part 711 is provided with an inclined surface 7111 on the side away from the baffle plate 3. After the plug is inserted, it acts on the inclined surface 7111 to squeeze the protection door 71 to be misaligned with the through hole 31, and the plug can be smoothly inserted into the spring sheet 4.

[0040] Reference Figure 5 , Figure 8 The panel 2 is fixedly connected with a positioning column 22, and the baffle 3 is provided with a positioning hole 34 for the positioning column 22 to be inserted. The position of the panel 2 is positioned to improve the relative fixing effect of the panel 2 and the baffle 3. The panel 2 is provided with a limiting wall 21 that presses against the end of the protection spring 72 away from the protection door 71. Reference Figure 6 , Figure 8 The protection part 711 is provided with a slot 7112 for inserting the protection spring 72, and a limiting column 714 for inserting the protection spring 72 is fixedly connected to the bottom wall of the slot 7112. The protection spring 72 is well limited, and is not prone to position deviation during repeated compression and stretching, thereby reducing the jamming of the protection door 71.

[0041] Reference Figure 6 , Fig. 9 A sliding post 713 is fixedly connected to one side of the protection portion 711 close to the baffle plate 3 . The baffle plate 3 is provided with a sliding hole 35 for the sliding post 713 to be inserted and slided. The sliding hole 35 is communicated with the through hole 31 .

[0042] Reference Figure 6 , Fig. 9The side of the connection part 712 close to the convex seat 32 is connected to the top strip 73, and the convex seat 32 is provided with a pressing hole 321 for the button 61 to pass through and a plug hole 322 for the top strip 73 to be inserted, and the plug hole 322 is connected with the pressing hole 321. When the connection part 712 is pressed against the convex seat 32, the top strip 73 is inserted into the plug hole 322 and passes through the pressing hole 321. The end of the top strip 73 close to the panel 2 is provided with a push-up inclined surface 731, and the button 61 is provided with a top hole 611 for the top strip 73 to be inserted, and the inner wall of the end of the top hole 611 away from the base 1 is a pressure inclined surface 612.

[0043] When the plug is not inserted, the protection door 71 is pressed against the protrusion 32. At this time, the top strip 73 is located at the lower end of the top hole 611, and the push-up bevel 731 cannot contact the pressure bevel 612. After the plug is inserted, the plug push-up button 61 moves downward and pushes the protection door 71 to move horizontally. During this process, the push-up bevel 731 and the pressure bevel 612 will not contact each other. After the plug is unplugged, if the protection door 71 is reset normally, but the button 61 is stuck and cannot rebound smoothly, the top strip 73 is inserted into the top hole 611, and the push-up bevel 731 can contact the pressure bevel 612, and then use the force of the button 61 to rebound, avoiding the trouble of the button 61 getting stuck, and improving the safety performance of the socket.

[0044] Reference Figure 6 , Fig. 9 The connecting portion 712 is provided with a connecting hole 7121 for the top strip 73 to pass through, the connecting portion 712 is plugged with a fixing strip 715, and the top strip 73 is provided with a fixing hole 732 for the fixing strip 715 to be inserted, so as to facilitate the installation of the protective door 71 and avoid the problem of inconvenience in installation caused by the top strip 73 being too long.

[0045] Reference Figure 8 The base 1 is threadedly connected with a stopper 9, which is inserted into the end of the slide hole 35 away from the through hole 31. When the elastic force of the protection spring 72 is insufficient, it can be replaced. After unscrewing the connecting screw 8 and removing the panel 2, the protection spring 72 can be replaced. During installation, the protection spring 72 is first compressed, and then the stopper 9 is screwed so that the stopper 9 limits the protection spring 72. Then, the panel 2 is installed, and finally the stopper 9 is screwed in the opposite direction so that the stopper 9 is misaligned with the protection spring 72, and the protection spring 72 is pressed against the limiting wall 21.

[0046] The implementation principle of the high-security socket of the embodiment of the present application is: Under normal circumstances, the button 61 automatically pops out under the action of the reset spring 65 after the plug is unplugged; if the reset spring 65 has insufficient elastic force or is stuck, the button 61 cannot be popped out smoothly. After the plug is unplugged, the protection door 71 is reset under the action of the protection spring 72, driving the top strip 73 to insert into the top hole 611, and also pushing the button 61 to pop out.

[0047] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
