Description

Technical Field

[0001] This application relates to the field of sockets, and more particularly to a high-safety socket. Background Technology

[0002] A power outlet, also known as a socket or switch socket, is used to receive electricity from a power source and supply power to other electrical appliances through a plug. Based on their functional characteristics, sockets can be divided into ordinary sockets, waterproof sockets, sockets with switches, and smart sockets. Sockets with switches typically have external switches, controlling the power on or off via a button, but this still poses a safety hazard of children accidentally touching them.

[0003] Chinese Patent No. CN218300479U discloses a switch-integrated socket, which includes an isolation component and a switch component. The isolation component includes a base, a protective plate, and a push structure. The push structure is used to push the protective plate to move. A guide structure is provided on one side of the protective plate. An electrical contact is provided inside the base. The switch component includes a trigger structure and a reset structure. A moving contact is provided on the trigger structure. A reset structure and a stationary contact are fixedly connected to the fixed base.

[0004] The switch in the aforementioned socket is built-in. When a plug is inserted into the socket, the plug comes into contact with the electrical contacts, squeezing the trigger mechanism. This, in turn, causes the moving contact to come into contact with the stationary contact, thus completing the current circuit within the socket. This socket ensures that current flows only when a plug is inserted, effectively reducing the safety hazard of accidental contact by children.

[0005] However, during use, the button may not spring back smoothly, and since the button is built-in, it is inconvenient to manually pull it out. Summary of the Invention

[0006] To ensure that the button rebounds smoothly, this application provides a high-safety socket.

[0007] The high-safety socket provided in this application adopts the following technical solution:

[0008] A high-safety socket includes a base and a panel connected to the base. The base is provided with a baffle, a spring, a grounding plate, a switching mechanism and a protection mechanism. The switching mechanism includes a button that slides through the baffle and the panel, a connector connected to the button, a moving contact inserted into the connector, a stationary contact inserted into the base, and a return spring disposed between the button and the base.

[0009] The protective mechanism includes a protective door disposed between the baffle and the panel, and a protective spring disposed between the protective door and the panel. The protective door is connected to a top strip, and a pushing slope is provided on the side of the top strip near the panel. The button is provided with a top hole for the top strip to be inserted. The inner wall of the end of the top hole away from the base is a pressure slope. When the button is pressed, the pushing slope can contact the pressure slope.

[0010] By adopting the above technical solution, under normal circumstances, the button will automatically pop out under the action of the reset spring after the plug is unplugged; if the reset spring is not elastic enough or is stuck, causing the button to fail to pop out smoothly, the protective door will reset under the action of the protective spring after the plug is unplugged, which will drive the top bar to insert into the top hole, and can also push the button out.

[0011] By utilizing the rebound force of the protective mechanism to power the switch mechanism, the button is subjected to the rebound force of both the reset spring and the protective spring, ensuring smooth button rebound, avoiding the problem of button jamming, and improving the safety performance of the socket.

[0012] Optionally, the protective door includes two protective parts and a connecting part connected between the two protective parts. The top strip is connected to the connecting part. The baffle is provided with a through hole for inserting a plug. The protective part is directly opposite the through hole. The protective part has an inclined surface on the side away from the baffle. The baffle has a protruding boss in the middle to block the connecting part. The boss is provided with a pressing hole for a button to pass through and an insertion hole for inserting the top strip. The insertion hole communicates with the pressing hole.

[0013] By adopting the above technical solutions, the protective door has a reasonable structural design and is less prone to jamming.

[0014] Optionally, the protective part is connected to a sliding column, and the baffle is provided with a sliding hole for the sliding column to be inserted and slid.

[0015] By adopting the above technical solutions, the smoothness of the sliding of the protective door is improved.

[0016] Optionally, the protective part is provided with a slot for inserting a protective spring, the bottom wall of the slot is connected to a limiting post for inserting the protective spring, the panel is provided with a limiting wall that abuts against the end of the protective spring away from the limiting post, and the panel and the base are connected by connecting screws.

[0017] By adopting the above technical solution, the protective spring is well limited and is not prone to positional deviation during repeated compression and stretching, thereby reducing the possibility of jamming of the protective door.

[0018] Optionally, the base is threadedly connected to a stop bar, which passes through a sliding hole and serves to limit and protect the spring.

[0019] By adopting the above technical solution, the protective spring can be replaced when its elasticity is insufficient. After unscrewing the connecting screws and removing the panel, the protective spring can be replaced.

[0020] During installation, first compress the protective spring, then turn the stop bar to limit the protective spring. Next, install the panel, and finally turn the stop bar in the opposite direction to misalign the stop bar with the protective spring, so that the protective spring presses against the limiting wall.

[0021] Optionally, the connecting part is provided with a connecting hole for the top strip to pass through, the connecting part is inserted with a fixing strip, and the top strip is provided with a fixing hole for the fixing strip to be inserted.

[0022] By adopting the above technical solution, the installation of the protective door is facilitated, avoiding the problem of inconvenience caused by an excessively long top strip.

[0023] Optionally, the base is connected to a hook, and the baffle is provided with a slot for the hook to engage.

[0024] By adopting the above technical solution, the installation of the baffle is facilitated.

[0025] Optionally, the panel is connected to a positioning post, and the baffle is provided with a positioning hole for the positioning post to be inserted.

[0026] By adopting the above technical solution, the position of the panel is positioned, and the relative fixation effect between the panel and the baffle is improved.

[0027] Optionally, the button includes a pressing rod, a pressing base connected to the pressing rod, and locking blocks connected to both sides of the pressing base. The connecting base is provided with locking holes for the locking blocks to be inserted, and the moving contact piece is clamped between the pressing base and the connecting base.

[0028] By adopting the above technical solution, the moving contact piece is easy to assemble.

[0029] Optionally, the connecting seat is provided with a limiting hole for the reset spring to pass through, and the pressing seat is connected with a limiting rod for inserting the reset spring.

[0030] By adopting the above technical solution, the reset spring is effectively limited, ensuring that its position is not easily deviated, thereby ensuring that the button rebounds smoothly.

[0031] In summary, this application has the following beneficial effects:

[0032] This application utilizes the rebound force of the protection mechanism to power the switch mechanism, ensuring that the button is not only subject to the rebound force of the reset spring but also to the rebound force of the protection spring. This guarantees that the button rebounds smoothly, avoids the problem of the button getting stuck, and improves the safety performance of the socket. Attached Figure Description

[0043] The following is in conjunction with the appendix Figure 1-9 This application will be described in further detail.

[0044] This application discloses a high-safety socket.

[0045] Reference Figure 1 , Figure 2 This high-safety socket includes a base 1, a panel 2, a baffle 3, spring contacts 4, a grounding plate 5, a switching mechanism 6, and a protection mechanism 7. Each of the four corners of the base 1 is fitted with connecting screws 8, which are threaded onto the panel 2, allowing for a detachable and fixed connection between the base 1 and the panel 2. The baffle 3 is snapped into the interior of the base 1, providing support and separation. Two spring contacts 4 are located on the side of the baffle 3 opposite to the panel 2, allowing the plug to be inserted and clamped. The grounding plate 5 is located inside the base 1, with both ends passing through the baffle 3 and the panel 2. The switching mechanism 6 is installed inside the base 1 to connect the circuit when the plug is inserted. The protection mechanism 7 is located between the baffle 3 and the panel 2 to prevent accidental contact by children.

[0046] 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, which makes it easy to fix the baffle 3 relative to the base 1 and to assemble.

[0047] Reference Figure 6 The switching mechanism 6 includes a button 61 that slides through the baffle 3 and the panel 2, a connecting seat 62 that engages with the button 61, a moving contact 63 inserted into the connecting seat 62, a stationary contact 64 inserted 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 connecting seat 62 moves down, causing the moving contact 63 to contact the stationary contact 64, thereby connecting the circuit.

[0048] Reference Figure 4 , Figure 7 Button 61 includes a pressing rod 613, which slides through the baffle 3 and the panel 2. A pressing seat 614 is fixedly connected to the lower end of the pressing rod 613. Locking blocks 615 are fixedly connected to both sides of the pressing seat 614. A limiting rod 616 is fixedly connected to the lower side of the pressing seat 614, and the limiting rod 616 inserts into the return spring 65 for positioning. The pressing seat 614 is inserted into a connecting seat 62, and the connecting seat 62 has a locking hole 621 for the locking blocks 615 to be inserted, thus fixing the button 61 and the connecting seat 62 relatively. The moving contact piece 63 is U-shaped and clamped between the pressing seat 614 and the connecting seat 62 in the middle. The connecting seat 62 has a limiting hole 622 in the middle for the return spring 65 to pass through, providing a good limiting effect for the return spring 65 and ensuring that its position does not easily deviate, thereby ensuring that the button 61 rebounds smoothly.

[0049] Reference Figure 5 , Figure 6The protective mechanism 7 includes a protective door 71 disposed between the baffle 3 and the panel 2. The protective door 71 is slidably connected to the baffle 3. A protective spring 72 is disposed between the protective door 71 and the panel 2. The protective spring 72 is used to apply a pushing force to the protective door 71, so that a certain force is required to push the protective door 71 open. The protective door 71 includes two protective parts 711 and a connecting part 712 fixedly connected between the two protective parts 711. A U-shaped groove is formed between the protective parts 711 and the connecting part 712. A protrusion 32 is formed in the middle of the baffle 3, which is inserted into the U-shaped groove. The protrusion 32 is used to block the connecting part 712 to limit the position of the protective door 71.

[0050] The baffle 3 has a through hole 31 for inserting a plug. One side of the through hole 31 is directly opposite the spring 4, and the other side is directly opposite the protective part 711. The protective part 711 has an inclined surface 7111 on the side away from the baffle 3. After the plug is inserted, it acts on the inclined surface 7111, squeezing the protective door 71 until it is misaligned with the through hole 31. At this time, the plug can be smoothly inserted into the spring 4.

[0051] Reference Figure 5 , Figure 8 Panel 2 is fixedly connected to a positioning post 22, and baffle 3 is provided with a positioning hole 34 for the positioning post 22 to be inserted. The position of panel 2 is positioned, improving the relative fixing effect between panel 2 and baffle 3. Panel 2 is provided with a limiting wall 21 at the end away from the protective door 71, which is a retaining spring 72.

[0052] Reference Figure 6 , Figure 8 The protective part 711 is provided with a slot 7112 for inserting the protective spring 72, and a limiting post 714 for inserting the protective spring 72 is fixedly connected to the bottom wall of the slot 7112. The protective spring 72 is well limited and is not prone to positional deviation during repeated compression and stretching, thereby reducing the possibility of jamming of the protective door 71.

[0053] Reference Figure 6 , Figure 9 The protective part 711 is fixedly connected to a sliding post 713 on the side near the baffle 3. The baffle 3 is provided with a sliding hole 35 for the sliding post 713 to be inserted and slid. The sliding hole 35 is connected to the through hole 31.

[0054] Reference Figure 6 , Figure 9A top strip 73 is connected to the side of the connecting part 712 near the boss 32. The boss 32 is provided with a pressing hole 321 for the button 61 to pass through and an insertion hole 322 for the top strip 73 to be inserted. The insertion hole 322 communicates with the pressing hole 321. When the connecting part 712 is pressed against the boss 32, the top strip 73 is inserted into the insertion hole 322 and passes through the pressing hole 321. A pushing slope 731 is provided on the side of the top strip 73 near the panel 2. The button 61 is provided with a top hole 611 for the top strip 73 to be inserted. The inner wall of the end of the top hole 611 facing away from the base 1 is a pressure slope 612.

[0055] When the plug is not inserted, the protective door 71 is pressed against the protrusion 32. At this time, the top bar 73 is located at the lower end of the top hole 611, and the pushing slope 731 cannot contact the pressure slope 612. After the plug is inserted, the plug pushing button 61 moves down and pushes the protective door 71 to move laterally. During this process, the pushing slope 731 and the pressure slope 612 will not come into contact. After the plug is unplugged, if the protective door 71 returns to its normal position, but the button 61 is stuck and cannot spring back smoothly, the top bar 73 is inserted into the top hole 611, and the pushing slope 731 can contact the pressure slope 612, thereby using the force to spring back the button 61, avoiding the problem of the button 61 getting stuck and improving the safety performance of the socket.

[0056] Reference Figure 6 , Figure 9 The connecting part 712 is provided with a connecting hole 7121 for the top strip 73 to pass through, and a fixing strip 715 is inserted into the connecting part 712. The top strip 73 is provided with a fixing hole 732 for the fixing strip 715 to be inserted, which facilitates the installation of the protective door 71 and avoids the problem of inconvenience in installation due to the top strip 73 being too long.

[0057] Reference Figure 8 The base 1 is threadedly connected to a stop bar 9, which passes through the end of the sliding hole 35 away from the through hole 31. The protective spring 72 can be replaced if its elasticity is insufficient. To replace it, unscrew the connecting screw 8 and remove the panel 2. During installation, first compress the protective spring 72, then screw the stop bar 9 to limit its movement. Next, install the panel 2, and finally screw the stop bar 9 in the opposite direction to misalign it with the protective spring 72, causing the protective spring 72 to press firmly against the limiting wall 21.

[0058] The implementation principle of the high-security socket in this application embodiment is as follows:

[0059] Under normal circumstances, after the plug is unplugged, button 61 will automatically pop out under the action of reset spring 65. If the reset spring 65 is not elastic enough or is stuck, causing button 61 to fail to pop out smoothly, after the plug is unplugged, the protective door 71 will reset under the action of protective spring 72, which will drive the top bar 73 to insert into the top hole 611, and can also push button 61 to pop out.

[0060] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
