A safety socket

Abstract

This invention relates to the field of household socket technology. This application discloses a safety socket, including a front panel and a rear shell that cooperate with each other. The back of the front panel is provided with a movable control switch lever, a sliding travel device, and a limiting structure. The travel device is equipped with a sealing plate that can block the socket. The rear shell is equipped with a power supply device. This device achieves normal sealing protection of the socket through structural cooperation. Only when a special plug is fully inserted into the socket can the travel device be squeezed to slide, and the linkage to the lever completes the conductive structure connection. On this basis, tossing the control switch lever will enable circuit conduction. If a foreign object is inserted or there is force on one side, the structure cannot be linked to conduction, and the switch cannot be operated alone. This invention effectively solves the safety hazards of traditional socket protective structure failure, foreign object insertion, and electric shock caused by accidental contact by children. The overall structure is compact and the linkage is reliable, which greatly improves the safety and stability of household sockets and is suitable for various household power supply scenarios.

Description

Technical Field

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

[0002] Sockets are commonly used power supply devices in daily life and industrial settings, with a wide range of applications. Currently, conventional sockets on the market only have simple socket holes and on / off switches, resulting in significant shortcomings in safety protection. Firstly, the socket holes are exposed for extended periods, allowing dust and moisture to easily penetrate, causing oxidation of conductive components, poor contact, shortening product lifespan, and potentially leading to short circuits. Secondly, exposed socket holes pose a significant safety hazard, as children can easily insert their fingers or metal objects into them, greatly increasing the risk of electric shock.

[0003] Some existing sockets with protective structures have simple protective mechanisms, relying solely on a single baffle and spring to block the sockets, resulting in flawed protection logic. When a foreign object is inserted into two sockets simultaneously, the baffle can easily be pushed open, triggering circuit continuity and failing to effectively prevent electric shock. Furthermore, most protective structures are independent of the on / off switch, allowing direct power even when no plug is inserted, resulting in insufficient safety redundancy. Additionally, traditional sockets lack a linkage design between on / off control and socket protection, leading to poor reset and linkage effects of protective components, a subpar user experience, and overall protection performance and reliability that fails to meet current high standards of safety. Therefore, there is an urgent need to optimize and improve the socket structure. Summary of the Invention

[0004] This application proposes a safety socket with high safety redundancy to solve the problem of electric shock caused by the easy opening of the cover of a traditional socket.

[0005] To achieve the above objectives, this application adopts the following technical solution: a safety socket, comprising a front panel and a rear housing, wherein the front panel has mounting holes, two-hole sockets and three-hole sockets on its front side, and control switch levers are movably mounted on the back of the front panel at positions on both sides of the mounting holes via connecting plates, a guide ramp is provided on the back of the front panel near the mounting holes, a spring connecting seat is provided on the back of the front panel near the guide ramp, slide rail seats are provided on the back of the front panel above the two-hole sockets and below the three-hole sockets, a slide rail is provided on the top of the slide rail seats, and a travel device is movably mounted on the slide rail, and side limiting seats are provided on the back of the front panel below the two-hole sockets and above the three-hole sockets, with a limit stop strip provided on one side of the side limiting seat.

[0006] Furthermore, the control switch paddle includes a left connecting seat and a right connecting seat respectively located on the two sides of the back of the paddle body near the middle. A left connecting shaft is fixedly installed on the outer side of the left connecting seat, and a transmission sleeve is fixedly installed on the inner side of the left connecting seat. One end of the transmission sleeve has a grooved transmission hole. A telescopic sleeve is fixedly fitted at the center of the right connecting seat. One end of the telescopic sleeve has a round hole, and an actuating device is movably installed inside the round hole through a telescopic cooperation. A positioning spring rod is fixedly installed at the center of the back of the paddle body.

[0007] Furthermore, a positioning plate is fixedly installed at the bottom of the inner wall of the rear housing corresponding to the position of the positioning spring top rod, a sliding groove is provided at the bottom of the inner wall of the rear housing corresponding to the position of the stroke device, the stroke device is located inside the sliding groove, and a power supply device is provided at the bottom of the inner wall of the rear housing near the positioning plate.

[0008] Specifically, the positioning plate is in contact with the top of the positioning spring rod.

[0009] Furthermore, the travel device includes a travel plate frame and a sliding seat. A sliding bar is provided on the top of the travel plate frame, a spring hinge is provided on the front side of the travel plate frame, a closing plate is sleeved on the side of the spring hinge near the top, and a connecting arm is fixedly installed at one end of the travel plate frame.

[0010] Specifically, a downward pressure plate is fixedly installed on the top of the sliding seat, and there are two downward pressure plates. When the socket is inserted through a two-hole or three-hole socket, the end of the plug will contact the inclined surface of the top of the downward pressure plate and push the entire stroke device to move to the side. A linkage push block is provided at one end of the top of the sliding seat. An installation groove is opened at the middle of the top of the stroke plate frame, and a first conductive sheet is provided inside the installation groove. A contact plate is provided on the outer surface of the first conductive sheet near the bottom end of the downward pressure plate. A second conductive sheet is provided on the front of the linkage push block. The second conductive sheet is connected to the first conductive sheet. One end of the sliding seat is connected to the connecting arm. A bottom slider is provided at the bottom of the sliding seat. A spring slide rod is slidably installed at the bottom of the bottom slider. The spring slide rod is fixedly installed inside the sliding groove. A contact plate is provided on the front of the second conductive sheet near one end.

[0011] Specifically, the sliding seat is slidably connected to the slide rail opened on the top of the slide rail seat. In the initial state, the closing plate is in contact with the inner wall of the front panel and closes the two-hole socket and the three-hole socket. In the initial state, both sides of the closing plate are in contact with the limit stop strip. When any single closing plate is in the open state, the entire stroke device is still in the locked state and cannot move.

[0012] Furthermore, there are two stroke devices with similar structures, the only difference being that their respective downward pressure plates correspond to the positions of the two-hole sockets and the three-hole sockets, respectively.

[0013] Furthermore, the actuating device includes two main rods, with a left connecting plate and a right connecting plate fixedly installed at each end. A transmission pin is fixedly installed on the outward side of the left connecting plate, and a telescopic spindle is fixedly installed on the inward side of the right connecting plate. A return spring is provided on the outward side of the right connecting plate. A third conductive sheet is fixedly sleeved on the outer surface of the main rod. There are two guide plates, which are initially in contact with the two third conductive sheets respectively. When the third conductive sheet is in contact with the guide plate, both the left and right connecting plates are in a horizontal state. Conductive contacts are provided on the outward side of the right connecting plate near both ends, and a closing contact is provided on the side of the third conductive sheet near the top.

[0014] Specifically, the transmission pin and the slotted transmission hole are on the same axis, the telescopic spindle is movably installed in the round hole at one end of the telescopic sleeve through a telescopic fit, and the reset spring is connected to the spring connecting seat.

[0015] Furthermore, the position of the electrical contact corresponds laterally to the position of the conductive contact. When the top of the downward pressure plate is subjected to downward pressure, it will drive the sliding seat to slide laterally, so that the electrical contact and the conductive contact come into contact and push the entire toggle device to move laterally synchronously.

[0016] Furthermore, the power supply device includes a fourth conductive sheet, on the front side of the fourth conductive sheet near both ends, a power supply contact is provided, and a wiring post is fixedly installed on the back side of the fourth conductive sheet near the middle, with a wiring contact provided on the top of the wiring post.

[0017] Furthermore, the third conductive sheet and the power supply contact are initially misaligned. After the entire toggle device is moved laterally, the third conductive sheet corresponds to the power supply contact, and the closing contact and the power supply contact remain separated.

[0018] This application has the following beneficial effects.

[0019] 1. When a foreign object is inserted into only one hole, the sealing plate cannot open synchronously, the travel device cannot move, the circuit is always open, and the risk of accidental contact is eliminated.

[0020] 2. When not in use, the sealing plate automatically seals the socket, preventing dust and liquid from entering, protecting the internal metal parts, and extending service life.

[0021] 3. When no plug is inserted, the toggle switch cannot conduct the circuit; even if two foreign objects are inserted, it will not trigger power, further improving safety.

[0022] 4. After the plug is inserted, power is turned on by simply flipping the switch once. There is no need to judge the initial state of the switch, making it simple and intuitive to use.

[0023] 5. The circuit is disconnected under normal conditions to avoid standby power consumption, thus saving energy and protecting the environment. Attached Figure Description

[0030] Please see Figures 5-7 The control switch lever 14 includes a lever body 141 with a left connecting seat 142a and a right connecting seat 142b respectively located on the two sides of the back near the middle. A left connecting shaft 143 is fixedly installed on the outer side of the left connecting seat 142a, and a transmission sleeve 144 is fixedly installed on the inner side of the left connecting seat 142a. One end of the transmission sleeve 144 has a grooved transmission hole 145. A telescopic sleeve 146 is fixedly fitted at the center of the right connecting seat 142b. One end of the telescopic sleeve 146 has a round hole, and a toggle device 21 is movably installed inside the round hole through telescopic cooperation. A positioning spring rod 147 is fixedly installed at the center of the back of the lever body 141.

[0031] Please see Figure 1 , Figure 4 and Figure 6 A positioning plate 31 is fixedly installed at the bottom of the inner wall of the rear housing 30, corresponding to the position of the positioning spring top rod 147. A sliding groove 32 is provided at the bottom of the inner wall of the rear housing 30, corresponding to the position of the stroke device 18. The stroke device 18 is located inside the sliding groove 32. A power supply device 33 is provided at the bottom of the inner wall of the rear housing 30 near the positioning plate 31. Please see Figure 4 and Figure 6 The top of the positioning plate 31 is in contact with the top of the positioning spring rod 147.

[0032] Please see Figures 11-13 The stroke device 18 includes a stroke plate frame 181 and a sliding seat 182. A sliding bar 183 is provided on the top of the stroke plate frame 181. A spring hinge 184 is provided on the front side of the stroke plate frame 181. A closing plate 185 is sleeved on the side of the spring hinge 184 near the top. A connecting arm 186 is fixedly installed on one end of the stroke plate frame 181. Please see Figures 11-13Two downward pressure inclined plates 187 are fixedly installed on the top of the sliding seat 182. When the socket is inserted through the two-hole socket 12 or the three-hole socket 13, the end of the plug will contact the inclined surface at the top of the downward pressure inclined plate 187 and push the stroke device 18 to move to the side. A linkage push block 188 is provided at one end of the top of the sliding seat 182. A mounting groove is provided at the top of the stroke plate frame 181 near the middle, and a first conductive sheet 189 is provided inside the mounting groove. The outer surface of the first conductive sheet 189 is close to the middle of the mounting groove. A contact plate 190 is provided at one end of the bottom of the downward pressure plate 187. A second conductive sheet 191 is provided on the front of the linkage push block 188. The second conductive sheet 191 is connected to the first conductive sheet 189. One end of the sliding seat 182 is connected to the connecting arm 186. A bottom slider 192 is provided at the bottom of the sliding seat 182. A spring slide rod 193 is slidably installed at the bottom of the bottom slider 192. The spring slide rod 193 is fixedly installed inside the sliding groove 32. A contact plate 194 is provided on one end of the front of the second conductive sheet 191.

[0033] The sliding seat 182 is slidably connected to the slide rail opened on the top of the slide rail seat 17. In the initial state, the closing plate 185 is in contact with the inner wall of the front panel 10 and closes the two-hole socket 12 and the three-hole socket 13. In the initial state, both sides of the closing plate 185 are in contact with the limit stop strip 20. When any single closing plate 185 is in the open state, the entire stroke device 18 is still in the locked state and cannot move.

[0034] Please see Figures 1-11 There are two stroke devices 18 with similar structures. The only difference is that their respective downward pressure plates 187 correspond to the positions of the two-hole sockets 12 and the three-hole sockets 13, respectively.

[0035] Please see Figures 8-9 The actuating device 21 includes two main rods 211, with a left connecting plate 212 and a right connecting plate 213 fixedly installed at each end. A transmission pin 214 is fixedly installed on the outward side of the left connecting plate 212, and a telescopic spindle 215 is fixedly installed on the inward side of the right connecting plate 213. A reset spring 216 is provided on the outward side of the right connecting plate 213. A third conductive sheet 217 is fixedly sleeved on the outer surface of the main rod 211. There are two guide plates 15, which are in contact with the two third conductive sheets 217 in the initial state. When the third conductive sheet 217 is in contact with the guide plate 15, both the left connecting plate 212 and the right connecting plate 213 are in a horizontal state. A conductive contact 218 is provided on the outward side of the right connecting plate 213 near both ends, and a connecting contact 219 is provided on the side of the third conductive sheet 217 near the top. Please see Figure 2 and Figures 7-8 The transmission pin 214 and the grooved transmission hole 145 are on the same axis. The telescopic spindle 215 is movably installed in the round hole at one end of the telescopic sleeve 146 through telescopic cooperation. The reset spring 216 is connected to the spring connecting seat 16.

[0036] Please see Figure 9 and Figure 13 The position of the energizing contact 194 corresponds laterally to the position of the conductive contact 218. When the top of the pressure plate 187 is subjected to downward pressure, it will drive the sliding seat 182 to slide laterally, so that the energizing contact 194 and the conductive contact 218 come into contact and push the toggle device 21 to move laterally as a whole.

[0037] When the plug is inserted, both closed plates 185 open simultaneously and disengage from the limit stop 20. When the plug end contacts the bottom slope of the pressure plate 187 and applies continuous downward pressure, the pressure plate 187 is subjected to lateral force, causing the stroke device 18 to slide laterally. This causes the linkage push block 188 to contact the conductive contact 218, closing the first switch. As the stroke device 18 continues to slide laterally, it pushes the toggle device 21 to slide laterally synchronously, causing the transmission pin 214 to insert into the slotted transmission hole 145 for engagement. At the same time, the energizing contact 219 moves to the position corresponding to the power supply contact 332. At this time, the toggle body 141 drives the toggle device 21 to rotate around the axis of the telescopic spindle 215, causing one of the energizing contacts 219 to contact the power supply contact 332 and making the entire device conductive, thereby supplying power to the electrical equipment.

[0038] Please see Figure 10 The power supply device 33 includes a fourth conductive sheet 331. Power supply contacts 332 are provided on both ends of the front side of the fourth conductive sheet 331. A wiring post 333 is fixedly installed on the back side of the fourth conductive sheet 331 near the middle. A wiring contact 334 is provided on the top of the wiring post 333.

[0039] When the plug is unplugged, the travel device 18 and the actuating device 21 are reset as a whole under the release of the elastic potential energy of the spring slide 193 and the return spring 216. During the reset process of the actuating device 21, the third conductive plate 217 contacts the guide inclined plate 15, thereby restoring the actuating device 21 to a horizontal state. This avoids the dangerous situation where the connecting contact 219 and the power supply contact 332 directly contact and conduct after the actuating device 21 slides laterally. At the same time, the sealing plate 185 rotates under the drive of the spring hinge 184 and closes the two-hole socket 12 or the three-hole socket 13 again. This effectively prevents external dust and splashed liquid from entering the device through the two-hole socket 12 or the three-hole socket 13 when the device is not in use, thus avoiding the problem of affecting the stability of power supply and causing corrosion of internal metal components, which would reduce the service life of the device. This provides practicality to the device.

[0040] Please see Figures 8-10 Initially, the third conductive sheet 217 and the power supply contact 332 are misaligned. After the toggle device 21 moves laterally as a whole, the third conductive sheet 217 corresponds to the power supply contact 332, and the connecting contact 219 and the power supply contact 332 remain separated.

[0041] Since the third conductive piece 217 and the fourth conductive piece 331 are initially misaligned, the device remains disconnected regardless of the position of the switch body 141 or how it is moved when no plug is inserted. This prevents energy loss caused by the device being constantly in a conductive state. Furthermore, the device can only be switched to a powered state by moving the control switch 14 after the plug is inserted into the two-hole socket 12 or the three-hole socket 13. This avoids the problem of the device being in standby mode and consuming energy due to accidental activation of the control switch 14. Additionally, if a child holds two foreign objects and inserts them into the two-hole socket 12 or the three-hole socket 13, the control switch 14 cannot be moved, thus preventing the device from switching to a conductive state and causing electric shock. This further enhances the safety of the device.

[0042] The method of using this invention is as follows: During use, when a child inserts a foreign object into the two-hole socket 12 or the three-hole socket 13, one of the sealing plates 185 is pushed open, while the other sealing plate 185 remains in its initial state and in contact with the limit stop 20. This prevents the travel device 18 from moving laterally when the foreign object contacts and presses down on the downward-pressing ramp 187. The electrical contact 194 remains separated from the conductive contact 218, keeping the entire device in an open-circuit state. Even if a foreign object slides down the downward-pressing ramp 187 and contacts the electrical contact 190, the electrical contact 190 remains de-energized, thus eliminating the danger. When the plug is inserted... When the plug is inserted, both sealing plates 185 can be opened simultaneously and disengaged from the limit stop bar 20. When the plug end contacts the bottom inclined surface of the downward pressure plate 187 and continues to apply downward pressure, the downward pressure plate 187 is subjected to a lateral force, causing the entire stroke device 18 to slide laterally, so that the linkage push block 188 contacts the conductive contact 218, realizing the first switch closure. As the entire stroke device 18 continues to slide laterally, it pushes the entire toggle device 21 to slide laterally synchronously, so that the transmission pin 214 is inserted into the slotted transmission hole 145 to achieve engagement, and at the same time, the connecting contact 219 moves to be in contact with the power supply contact 332. At the corresponding position, the toggle switch body 141 drives the toggle device 21 to rotate around the axis of the telescopic spindle 215, causing one of the connecting contacts 219 to contact the power supply contact 332 and making the entire device conductive. When the plug is pulled out, under the release of the elastic potential energy of the spring slide 193 and the return spring 216, the stroke device 18 and the toggle device 21 are reset. During the reset process of the toggle device 21, the third conductive plate 217 contacts the guide inclined plate 15, thereby restoring the toggle device 21 to a horizontal state. At the same time, the sealing plate 185 is on the spring hinge 184. The device rotates down and closes the two-hole socket 12 or the three-hole socket 13 again. Since the third conductive piece 217 and the fourth conductive piece 331 are initially misaligned, the device remains in the off state regardless of the position of the switch body 141 or how it is moved when no plug is inserted. When the plug is inserted, the device can be switched to the on state and powered on the appliance simply by moving the switch body 14 once, regardless of its position. The user does not need to distinguish the on / off state of the switch body 14.
