Technical Field

[0001] This utility model relates to the field of household appliance technology, specifically to a wall switch socket with easily replaceable wiring terminals. Background Technology

[0002] In existing technology, the wiring terminal slots of wall switches and sockets are installed inside the socket body. When the wiring terminals age and are damaged, the switch and socket need to be removed from the wall and disassembled as a whole. First, the panel, then the middle plate and safety door and other structures need to be removed. Only after removing the copper sheet can the wiring terminals be replaced. The operation process is very cumbersome. It not only requires a variety of professional disassembly and assembly tools, but may also damage the original internal wiring due to misoperation, leaving electrical safety hazards. Utility Model Content

[0003] In view of this, the present invention provides a wall switch socket with easily replaceable wiring terminals.

[0004] To achieve the above objectives, this utility model provides the following technical solution:

[0005] A wall switch socket with easily replaceable terminal blocks includes a base and a panel disposed on one side of the base. A detachable terminal block module is disposed on the outer wall of the base, and a conductive sheet assembly is disposed inside the base. After the terminal block module is connected to the base, the conductive sheet assembly inside the base is connected to the terminal block module.

[0006] Preferably, the terminal block module includes a terminal housing and a terminal body disposed within the terminal housing. The terminal housing has an insertion interface. The conductive sheet assembly in the base extends out of the base and enters the terminal housing through the insertion interface to connect with the terminal body. The terminal housing and the base are detachably connected.

[0007] Preferably, the base has a slot on at least one side surface, the terminal block module is detachably disposed in the slot, the terminal housing of the terminal block module is provided with an elastic snap-fit ​​structure, and the slot wall of the slot is provided with a slot limiting structure that engages with the elastic snap-fit ​​structure. The engagement between the elastic snap-fit ​​structure and the slot limiting structure limits the position of the terminal block module in the slot.

[0008] Preferably, the slot limiting structure is disposed on the two opposite sides of the slot, and the elastic snap-fit ​​structure is disposed on both sides of the terminal housing corresponding to the slot limiting structure. The elastic snap-fit ​​structure is a snap-fit ​​arm disposed on the terminal housing. One end of the snap-fit ​​arm is connected to the terminal housing, and the other end of the snap-fit ​​arm extends toward one side of the terminal housing and forms a deformation gap with the terminal housing. The snap-fit ​​arm is provided with a snap-fit ​​arm limiting part corresponding to the slot limiting structure, and the snap-fit ​​arm limiting part is in concave-convex fit with the slot limiting structure.

[0009] Preferably, the locking arm limiting part is a limiting end protruding on the locking arm, and the locking groove limiting structure is a limiting groove formed inward on the groove wall corresponding to the limiting end on the locking arm. The limiting end extends into the limiting groove and connects with the base for limiting. When it is necessary to disassemble the terminal block module, press the locking arms on both sides. After the locking arms are subjected to pressure, they retract inward along the deformation gap, causing the limiting end to come out of the limiting groove of the locking groove. The entire terminal block module can then be pulled out of the locking groove of the base to complete the replacement.

[0010] Preferably, the slot has an open structure, with an inlet slot and a terminal mounting slot. The terminal module enters the slot through the terminal mounting slot, and the base is provided with a push-button limiting structure to limit the terminal module in the direction of the inlet slot.

[0011] Preferably, the push button limiting structure includes a push button body and an elastic element. A push button groove is formed on the base. The elastic element is disposed in the push button groove. One end of the push button body extends into the push button groove. The two ends of the elastic element abut against one side wall of the push button groove and the end of the push button body extending into the push button groove, thereby providing an elastic pushing force to the push button body toward the inlet slot.

[0012] Preferably, the panel is provided with a USB port and a Type-C port, and the base is provided with a detachable port circuit board, which is electrically connected to the USB port and the Type-C port.

[0013] Preferably, a circuit board mounting groove is formed in the base, the plug-in circuit board is disposed in the circuit board mounting groove, a mounting opening is provided on the side of the circuit board mounting groove away from the panel, the plug-in circuit board enters the circuit board mounting groove through the mounting opening, and a cover plate is provided at the mounting opening to seal the mounting opening.

[0014] Preferably, the conductive sheet assembly includes a live wire conductive sheet and a neutral wire conductive sheet disposed inside the base. The base has a conductive sheet outlet, through which the live wire conductive sheet and the neutral wire conductive sheet extend into the base. A ground wire conductive sheet is disposed on the outer wall of the base. One end of the ground wire conductive sheet extends toward the terminal block module and, together with the live wire conductive sheet and the neutral wire conductive sheet, extends into the terminal housing through a connector and connects to the terminal body.

[0015] The beneficial effects of this utility model are as follows: By setting the terminal block module on the outer wall of the base and detachably connecting it to the base, wiring operations are no longer limited by the narrow space of the wall mounting groove. Construction workers can remove the terminal block module and perform wire stripping and fixing operations in an open area, then reassemble the terminal block module with the wires connected back into the base. This reduces the difficulty of wiring operations and effectively improves on-site construction efficiency. Furthermore, when subsequent wiring modifications or socket replacements are needed, simply remove the socket from the wall and directly disassemble the terminal block module. Compared to the existing technology where the terminal block is located inside the socket, wiring adjustments can be completed without disassembling the socket, preventing additional damage to the socket body and the base's fixing structure.

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0026] The present invention will now be further described with reference to the accompanying drawings.

[0027] This utility model provides the following technical solution:

[0028] As attached Figure 1-8 As shown, this utility model discloses a wall switch socket with easily replaceable wiring terminals, including a base 1 and a panel 2 disposed on one side of the base 1. A detachable wiring terminal module 3 is disposed on the outer wall of the base 1, and a conductive sheet assembly 4 is disposed inside the base 1. After the wiring terminal module 3 is connected to the base 1, the conductive sheet assembly 4 inside the base 1 is connected to the wiring terminal module 3. Specifically, in this design, by placing the wiring terminal module 3 on the outer wall of the base 1 and detachably connecting it to the base 1, the wiring operation is no longer limited by the narrow space of the wall mounting groove. Construction workers can remove the wiring terminal module 3, perform wire stripping and fixing operations in an open area, and then reassemble the wired terminal module back into the base 1 to complete the assembly. This reduces the difficulty of the wiring operation and effectively improves the efficiency of on-site construction. When it is necessary to modify the wiring or replace the socket in the future, you only need to remove the socket from the wall and then directly disassemble the wiring terminal module 3 on the socket. Compared with the existing technology where the wiring terminal is located inside the socket, the wiring adjustment can be completed without disassembling the socket, and will not cause additional damage to the fixing structure of the socket body and the base 1.

[0029] Furthermore, the terminal block module 3 includes a terminal housing 5 and a terminal body 6 disposed within the terminal housing 5. The terminal housing 5 has a connector 7. The conductive sheet assembly 4 within the base 1 extends out of the base 1 and enters the terminal housing 5 through the connector 7 to connect with the terminal body 6. The terminal housing 5 and the base 1 are detachably connected. Specifically, in this embodiment, through a modular, split-structure design, the wiring function originally integrated into the socket base 1 is separated, preserving the conductivity reliability of the original switch socket while optimizing the wiring and maintenance process. The conductive sheet assembly 4 passes through the connector 7 of the terminal housing 5 and contacts the terminal body 6. The elastic stress of the conductive sheet ensures a consistently tight contact, preventing poor contact due to disassembly and reassembly of the terminal module, thus adapting to the needs of repeated replacements.

[0030] Specifically, the conductive sheet assembly 4 includes a live wire conductive sheet 8 and a neutral wire conductive sheet 9 disposed inside the base 1. A conductive sheet outlet 10 is provided on the base 1, through which the live wire conductive sheet 8 and the neutral wire conductive sheet 9 extend into the base 1. A ground wire conductive sheet 11 is disposed on the outer wall of the base 1, with one end extending towards the terminal module 3 and extending through the connector 7 along with the live wire conductive sheet 8 and the neutral wire conductive sheet 9 into the terminal housing 5, connecting to the terminal body 6. Specifically, in this embodiment, the live wire and neutral wire conductive sheets 9 are disposed inside the base 1 and extend through the conductive sheet outlet 10, while the ground wire conductive sheet 11 is directly disposed on the outer wall of the base 1 to accommodate wiring positions. This satisfies the wiring requirements of household power supply lines and utilizes the internal structure of the base 1 to protect and limit the live wire and neutral wire conductive sheets 9, preventing deformation and misalignment due to external forces. The position of each conductive piece corresponds one-to-one with the plug interface 7 of the terminal module 3. When installing the terminal module, simply align the position and push it in to automatically connect each conductive piece to the corresponding terminal body 6. There will be no problem of misconnection or omission, which further reduces the probability of assembly wiring errors. The base 1 has a protruding ground wire positioning end 12. The ground wire conductive sheet 11 has a positioning hole 13. The ground wire positioning end 12 extends into the positioning hole 13 and limits the position of the ground wire conductive sheet 11 on the base 1. Furthermore, ground wire connection holes 14 are opened at both ends of the ground wire conductive sheet 11 along its length. The base 1 and the panel 2 have mounting holes corresponding to the ground wire connection holes 14. Fasteners pass through the mounting holes on the panel 2, the mounting holes on the base 1, and the ground wire connection holes 14 in sequence and are connected to the switch and socket mounting box (not shown) on the wall. This achieves double fixing of the ground wire conductive sheet 11, which not only ensures the stability of the grounding connection, but also completes the fixing of the entire socket to the wall-embedded mounting box with the help of the connection holes on the ground wire conductive sheet 11. This integrates the dual functions of grounding connection and socket installation, simplifies the structural design of the base 1, reduces unnecessary fixing components, and also reduces the cost of mold processing and assembly.

[0031] Furthermore, a slot 15 is formed on at least one side surface of the base 1, and the terminal block module 3 is detachably disposed within the slot 15. An elastic snap-fit ​​structure 16 is provided on the terminal housing 5 of the terminal block module 3. A slot limiting structure 17, corresponding to the elastic snap-fit ​​structure 16, is provided on the slot wall of the slot 15, engaging with the elastic snap-fit ​​structure 16. The engagement between the elastic snap-fit ​​structure 16 and the slot limiting structure 17 limits the position of the terminal block module 3 within the slot 15. Specifically, in this embodiment, the terminal block module 3 is entirely embedded in the pre-set slot 15 on the outer wall of the base 1. This avoids protruding from the surface of the base 1 and affecting the fit of the panel 2 to the wall, while also providing initial positioning and limiting of the terminal block module 3, preventing it from shaking or shifting after installation. The interlocking mechanism 16 and the slot limiting mechanism 17 allow for locking with just a push, and the terminal block module 3 can be quickly disassembled without the need for other special tools, further optimizing the disassembly and assembly experience and meeting the needs of on-site construction and subsequent maintenance.

[0032] Furthermore, the slot limiting structure 17 is disposed on the opposite side walls of the slot 15, and the elastic snap-fit ​​structure 16 is disposed on both sides of the terminal housing 5 corresponding to the slot limiting structure 17. The elastic snap-fit ​​structure 16 is a snap-fit ​​arm disposed on the terminal housing 5, one end of the snap-fit ​​arm is connected to the terminal housing 5, and the other end of the snap-fit ​​arm extends toward one side of the terminal housing 5 and forms a deformation gap 18 with the terminal housing 5. The snap-fit ​​arm is provided with a snap-fit ​​arm limiting part 19 corresponding to the slot limiting structure 17, and the snap-fit ​​arm limiting part 19 is in concave-convex fit with the slot limiting structure 17. Specifically, in this embodiment, the snap-fit ​​structure is integrated on both sides of the terminal housing 5, eliminating the need for additional third-party locking components. This simplifies the overall structure of the terminal module 3 and ensures uniform force on both sides, preventing the terminal module 3 from tilting on one side after locking. The deformation gap 18 reserved between the snap-fit ​​arm and the terminal housing 5 provides sufficient deformation space for the snap-fit ​​arm. When pushed into the snap-fit ​​slot 15, the snap-fit ​​arm is squeezed and contracted by the slot wall. After it is in place, the snap-fit ​​arm resets by its own elasticity, allowing the snap-fit ​​arm limiting part 19 to automatically engage and lock with the snap-fit ​​slot limiting structure 17. The operation process is smooth and unobstructed, further improving the assembly and disassembly efficiency of the terminal module 3.

[0033] Furthermore, the locking arm limiting part 19 is a limiting end protruding from the locking arm, and the locking groove limiting structure 17 is a limiting groove corresponding to the limiting end on the locking arm, which is recessed into the groove wall of the locking groove 15. The limiting end extends into the limiting groove and is limited to the base 1. When it is necessary to disassemble the terminal block module 3, press the locking arms on both sides. After the locking arms are subjected to pressure, they retract inward along the deformation gap 18, causing the limiting end to come out of the limiting groove of the locking groove 15. The entire terminal block module 3 can then be pulled out of the locking groove 15 of the base 1 to complete the replacement. Specifically, in this embodiment, the matching structure of the limiting end and the limiting groove is simple and reliable, has low processing difficulty, and will not automatically loosen under external force vibration after locking, ensuring the fixed stability of the terminal block module 3 on the base 1. Disassembly can be completed simply by pressing the locking arms on both sides, simplifying the process of electricians replacing and rewiring. Even in scenarios with limited operating space, such as wall mounting slots, the terminal modules can be quickly removed without any operational hindrance due to the small space. Furthermore, there is no need to pry and damage the socket body or wall structure, further meeting the actual needs of on-site construction and subsequent maintenance.

[0034] Furthermore, the slot 15 has an open structure, with an inlet slot 20 and a terminal mounting slot 21. The terminal module 3 enters the slot 15 through the terminal mounting slot 21. The base 1 is provided with a push-button limiting structure 22 that limits the terminal module 3 in the direction of the inlet slot 20. Specifically, in this embodiment, the inlet slot 20 of the slot 15 ensures that the wiring side of the terminal module 3 is not obstructed after installation. External wires can directly enter the terminal module from the inlet slot 20 to complete the connection without additional bending to avoid the base 1 structure. Even thicker hard wires can be smoothly connected, adapting to different specifications of home power supply lines. The terminal mounting slot 21 is used for installing the terminal block module 3. After the terminal block module 3 is pushed into the slot 15 through the terminal mounting slot 21, it can be initially locked by the elastic snap-fit ​​structure 16, and then finally fixed by the push button limiting structure 22. The entire installation process does not require tightening screws, and the operation process is smooth and seamless. The open slot 15 design also eliminates the requirement of reserving space for wire exit in the closed slot 15, and there is no need to process the wire exit structure in the base 1. This reduces the processing complexity of the base 1 mold, lowers the defect rate of injection molding, and further controls the production cost of the product.

[0035] Furthermore, the push button limiting structure 22 includes a push button body 23 and an elastic element 24. A push button groove 25 is provided on the base 1. The elastic element 24 is disposed in the push button groove 25. One end of the push button body 23 extends into the push button groove 25. The two ends of the elastic element 24 abut against one side wall of the push button groove 25 and the end of the push button body 23 extending into the push button groove 25, thereby providing an elastic pushing force to the push button body 23 toward the wire inlet slot 20. Specifically, in this embodiment, under normal conditions, the elastic element 24 always provides a pushing force to the push button body 23 toward the inlet slot 20. During the process of pushing the terminal module 3 into the slot 15, the end face of the terminal module 3 will push the push button body 23 away, causing the push button body 23 to retract along the push button slide 25 and compress the elastic element 24, which will not hinder the installation of the terminal module. When the terminal module 3 is fully inserted into the slot 15, the side end face of the terminal module 3 no longer blocks the push button body 23, and the elastic element 24 immediately pushes the push button body 23 to reset and extend. The side wall of the push button body 23 directly fits against the side wall of the terminal module 3 toward the inlet slot 20, completing the axial positioning of the terminal module 3. This process does not require manual pushing of the push button and can automatically complete the positioning as the terminal module 3 is installed, further simplifying the installation operation steps. When it is necessary to disassemble the terminal block module 3, simply push the push button body 23 away from the wire inlet slot 20 to retract the compression elastic element 24 to make room for removal, and then press the two side locking arms to pull out the terminal block module. The operation logic is simple and clear.

[0036] Furthermore, the panel 2 is equipped with a USB port 26 and a Type-C port 27, and the base 1 contains a detachable port circuit board 28, which is electrically connected to the USB port 26 and the Type-C port 27. Specifically, in this embodiment, the addition of the USB port 26 and the Type-C port 27 can meet the direct charging needs of small mobile electronic devices such as mobile phones and tablets, eliminating the need for an additional charger, thus enriching the functionality of the wall switch socket and adapting to the diverse needs of current home electrical installations. The port circuit board 28 is independently designed as a replaceable structure. When the port is damaged or a higher power charging specification needs to be upgraded, the port circuit board 28 can be replaced separately without replacing the entire wall switch socket, further adapting to user upgrade needs and extending the overall lifespan of the product.

[0037] Furthermore, a circuit board mounting groove 29 is formed within the base 1, and the plug-in circuit board 28 is disposed within the circuit board mounting groove 29. A mounting slot 30 is provided on the side of the circuit board mounting groove 29 away from the panel 2. The plug-in circuit board 28 enters the circuit board mounting groove 29 through the mounting slot 30. A cover plate 31 is provided at the mounting slot 30 to seal it. Specifically, in this embodiment, the plug-in circuit board 28 is inserted through the mounting slot 30 on the back of the socket, allowing for replacement and upgrades without disassembling the panel 2. The operation does not damage the wall surface and does not require moving the already wired terminal modules, further simplifying the upgrade and maintenance process. After the cover plate 31 seals the mounting slot 30, it protects the plug-in circuit board 28, preventing dust accumulation and moisture from causing circuit failures, thus improving the stability and safety of power supply. The plug-in circuit board 28 is a consumable component; the easy replacement method also facilitates cost reduction. Furthermore, USB upgrades are rapid, and the replacement PCBA can keep pace with development.

Various modifications to these embodiments will be readily apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present invention.
