Description

Technical Field

[0001] This utility model relates to the field of wall switch and socket technology, specifically to a wall socket with a switch indicator. Background Technology

[0002] A wall switch is an electrical switch installed on a wall. It typically includes a housing and an electrical connection assembly. The housing is fixed to the wall and includes a panel extending to the outer surface of the wall and a base placed inside the wall. The electrical connection assembly includes a contact group and a switch button that controls the on / off state between the stationary and moving contacts in the contact group. The contact group is housed within the housing, and the base allows the connecting wires of the household appliances to pass through the housing and form an electrical connection with the contact group. The main body of the wall switch is embedded in the wall. The switch button is pivotally mounted on the panel, which has a first position and a second position corresponding to the on / off state of the contact group. By pressing the switch button, it can make contact with the first or second position on the panel, thereby connecting or disconnecting the power supply.

[0003] However, existing wall switches generally either have indicator lights to show the switch position in the dark, or they have sockets that light up when plugged in, or they have sockets with slots and switches that disconnect the slot via the switch. However, these existing wall switches only provide a limited range of functions. When some devices need to be completely powered off after being turned off, the plug still needs to be unplugged. And with ordinary wall switches that disconnect the slot, workers cannot reliably ensure that the power is completely cut off, which presents an uncertainty problem. Utility Model Content

[0004] In view of the prior art, the purpose of this utility model is to provide a wall socket with a switch indicator, which not only has the function of cutting off the power to the socket, but also indicates whether the power is cut off correctly to ensure use.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows: a wall socket with a switch indicator, comprising a switch body, the switch body including a cover and a back plate, the cover having a three-hole slot and a switch button with a built-in indicator light, the three-hole slot having a trigger element, the back plate having a conductive element L, a conductive element N, and a conductive element P, the conductive element L being connected to an external power supply line and the switch button and one of the conductive elements in the three-hole slot, the conductive elements N and P being respectively connected to the external power supply line and the conductive elements in the other two slots of the three-hole slot, the switch button being used to control the circuit of the conductive element L, and the indicator light being connected to the circuit of the conductive element L and the indicator light being connected by the trigger element control circuit, so that the circuit of the indicator light is activated when the plug is inserted into the three-hole slot.

[0007] Preferably, the trigger includes a return spring, a moving member, a moving contact, and a stationary contact, wherein the moving contact is disposed on the moving member, and the moving member is disposed opposite the three-hole slot.

[0008] Preferably, the moving part also has a baffle and a ramp, the ramp is located in the hole groove corresponding to the conductive part P, the baffle extended from the moving part is located in the hole groove opposite to the conductive parts L and N, and one end of the reset spring abuts against the inner wall of the hole groove and the other end abuts against the moving part to block the three-hole slot.

[0009] Preferably, the back plate is provided with a neutral wire interface, a live wire interface and a ground wire interface, and each of the neutral wire interface, the live wire interface and the ground wire interface is provided with a wire post and a locking bolt.

[0010] Beneficial effects: The wall switch of this utility model features the ability to control the power supply to the socket slot through a switch button. The switch allows for independent control of the on / off state of a single plug. In practical applications, for some long-term installed devices, the power supply can be disconnected by pressing the switch button after shutdown without unplugging the plug. This reduces plug insertion and removal, reduces wear and tear on the device power plug and wall socket, and extends service life. Furthermore, the indicator light allows staff to quickly determine whether the plug is powered on. In the case of disconnecting the device power supply without unplugging the plug, the indicator light quickly determines whether power is supplied, allowing for switching control of power supply via the switch button.

[0016] To better understand the above-mentioned objectives, features, and advantages of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings and specific embodiments. It should be noted that, where there is no conflict, the embodiments and features described in these embodiments can be combined with each other.

[0017] like Figure 1-4 The wall socket with a switch indicator shown includes a switch body 1, which includes a cover 11 and a back plate 12. The cover 11 has a three-hole slot 13 and a switch button 14 with an indicator light 15 built in. The three-hole slot 13 has a trigger element 3. The back plate 12 has a conductive element L21, a conductive element N22, and a conductive element P23. The conductive element L21 is connected to an external power supply line and to the conductive element of one hole of the three-hole slot 13. The conductive elements N22 and P23 are respectively connected to the external power supply line and to the conductive elements of the other two holes of the three-hole slot 13. The switch button 14 is used to control the circuit of the conductive element L21. The indicator light 15 is connected to the circuit of the control circuit through the trigger element 3, so that the circuit of the conductive element L21 and the indicator light 15 is activated when the plug is inserted into the three-hole slot 13.

[0018] As a further feature of the above solution, the indicator light 15 is provided with a conversion circuit board, the switch button 14 is provided with an inner groove, the LED of the indicator light 15 extends into the inner groove, and the outer shell of the switch button 14 is made of light-transmitting plastic material.

[0019] As a further provision of the above scheme, the trigger 3 includes a reset spring 31, a moving member 32, a moving contact 33, and a stationary contact 34. The moving contact 33 is located on the moving member 32, and the moving member 32 is positioned opposite the three-hole slot 13.

[0020] As a further provision of the above scheme, the moving member 32 is also equipped with a baffle and a slope member. The slope member is located in the slot corresponding to the conductive member P23. The baffle extended from the moving member 32 is located in the slots opposite to the conductive members L21 and N22. One end of the reset spring 31 abuts against the inner wall of the slot and the other end abuts against the moving member 32 to block the three-hole slot 13.

[0021] As a further feature of the above solution, the back plate 12 is provided with a neutral wire interface 121, a live wire interface 122 and a ground wire interface 123, and each of the neutral wire interface 121, the live wire interface 122 and the ground wire interface 123 is provided with a wire post 124 and a wire locking bolt 125.

[0022] This utility model's wall socket uses a switch button 14 to control the power supply to the corresponding three-hole slot 13. The user can press the switch button 14 to cut off the continuity of the live wire in the three-hole slot 13, thus controlling whether the socket is energized. This technology includes a knife switch controlled by the switch button 14 installed in the back panel 12, which disconnects or connects the live wire connected to the switch button 14. It is worth noting that in this embodiment, the indicator light 15 is connected in parallel to the three-hole slot 13. When the switch button 14 is in the open state, the circuit inside the three-hole slot 13 is conductive, but there is no external plug. When a plug is inserted, the moving contact 33 on the trigger 3 separates from the stationary contact 34, so the switching circuit of the indicator light 15 is not energized and will not light up. When a plug is inserted into the three-hole slot 13, the moving contact 33 and the stationary contact 34 on the trigger 3 become electrically connected, so the indicator light 15 indicates that the socket is energized. The advantage of this is that the switch button 14 can control whether the socket is energized in the three-hole slot 13, and the indicator light 15 will only light up when the socket is energized. Therefore, after the plug is inserted into the socket, the user can determine whether the socket is energized and whether it is supplying power by pressing the switch button 14 and observing the indicator light 15.

[0023] As described in the structure of this embodiment, during wiring, the external live wire, neutral wire, and ground wire are connected to the corresponding power neutral wire interface 121, live wire interface 122, and ground wire interface 123 on the back panel 12. Further, as... Figure 4 As shown, a trigger 3 is provided inside the three-hole slot 13. The trigger 3 includes a moving part 32 and a reset spring 31 for driving the moving part 32 to move and reset. The moving part 32 is provided with a beveled head and a moving contact 33. A stationary contact 34 is provided on the side wall of the slot hole for the grounding wire in the three-hole slot 13. After the plug is inserted, the front end of the grounding pin pushes the moving part 32 to move. The moving contact 33 contacts the stationary contact 34 to conduct light to the indicator light 15. It is worth noting that after the grounding pin passes through the area of ​​the moving part 32, it extends into the conductive plate connected to the grounding wire on the rear side. The moving part 32 will not affect the grounding.

[0024] As described in this embodiment, the live wire connected to the live wire interface 122 passes through the switch button 14 and then enters the three-hole slot 13. The neutral wire connected to the neutral wire interface 121 is directly connected to the three-hole slot 13. In use, the switch button 14 can be used to directly cut off the live wire connection. The conversion circuit of the indicator light 15 can convert the 220V household electricity to the 5V power of the indicator light 15 bulb. It is worth noting that the conversion circuit in this embodiment is connected in parallel between the switch button 14 and the three-hole slot 13. In this way, when the plug is inserted, the switch button 14 can simultaneously control the live wire connection and the indicator light 15. That is, the socket in this embodiment will have the following state when in use:

[0025] ① Normal working state: The plug is plugged in and there is power (indicator light 15 is on): At this time, the plug is plugged in and the moving part 32 is moved by the ramp part, which not only opens the slots of the live wire and the neutral wire, but also drives the moving contact 33 to contact the stationary contact 34 to conduct. Based on the closing of the switch button 14, the entire circuit is fully connected, the indicator light 15 is on, and the corresponding three-hole slot 13 is connected.

[0026] ② No power state 1: No power when plug is inserted (indicator light 15 does not light up): Because the plug is inserted, the moving part 32 moves, so the moving contact 33 and the stationary contact 34 are in contact, thereby changing the circuit path and the circuit of indicator light 15 is connected. However, because the switch button 14 is disconnected at this time, the live wire is disconnected. Therefore, there is no power in the three-hole slot 13 and the indicator light 15 is not powered.

[0027] ③ No power supply state two: plug not inserted but power is on (indicator light 15 is not on): the moving part 32 is kept in a state of separation from the stationary contact 34 under the drive of the reset spring 31, thereby disconnecting the conversion circuit. Whether the switch button 14 is on or off, at this time no plug is inserted, the sliding of the moving part 32 can also block the live wire hole and the neutral wire hole, which can also play a protective role.

[0028] As described above, in the working state, the user can intuitively determine whether the socket is powered through the indicator light 15. Compared with the prior art, the socket in this embodiment can control whether the socket is powered by observing the indicator light 15 and operating the switch button 14 when a plug is inserted. In addition, the addition of the trigger element 3 avoids the situation where the light button of the prior art will light up when no plug is inserted.

[0029] The wall socket in this embodiment, as described above, features a switch button 14 that controls the power supply to the socket slot. The switch allows for independent control of the on / off state of a single plug. In practical applications, this addresses the need to completely disconnect power to devices that have been continuously powered on for extended periods, even when switched off and in standby mode. Existing technologies typically involve unplugging the device or using a socket switch with a power-off knife switch. However, to avoid unclear on / off states caused by the knife switch, and to prevent situations where the device appears to be disconnected but is not, the wall switch in this embodiment improves upon the ordinary knife switch in its structure. This improvement allows the switch button 14 to close the circuit and the plug to be inserted into the socket. When the device is in use, indicator light 15 indicates that it is powered on, allowing staff to clearly understand whether the three-hole slot 13 of the socket is powered on or off. This enables them to accurately disconnect the power supply by pressing the switch button 14 without unplugging the plug, reducing the need for plugging and unplugging, minimizing wear on the device's power plug and wall socket, and extending their service life. Furthermore, the indicator light 15 allows staff to quickly ascertain whether the plug is powered on. In the case of disconnecting the device's power supply without unplugging the plug, indicator light 15 can quickly determine whether power is supplied, and the switch button 14 can be used to switch the power supply status.

[0030] Obviously, those skilled in the art can make various modifications and variations to this utility model without departing from its spirit and scope. Therefore, if these modifications and variations fall within the scope of this utility model and its equivalents, this utility model also intends to include these modifications and variations.
