Description

Technical Field

[0001] This invention relates to the field of junction box technology, and more particularly to junction box structures for intelligent switch sockets. Background Technology

[0002] The recessed box structure for smart switches and sockets refers to a standardized electrical installation box pre-embedded inside the building wall, specifically designed for installing smart switches or smart sockets. Its structural design must take into account both traditional electrical functions and the special needs of smart devices.

[0003] Chinese Patent Publication No. CN208548672U, published on 20190226, discloses a switch and socket concealed box, which includes a box body, a nut, and a mounting ear plug. The box body includes a box body and a panel mounting ear. The panel mounting ear is set as a hollow column with an open bottom and a panel connection hole at the top. The box body is provided with a mounting ear plug engaging groove with an open bottom. The mounting ear plug includes a nut limiting part and a engaging part. The nut limiting part is integrally set on the upper part of the engaging part and is set as a hollow structure. The nut limiting part and the panel mounting ear form a plug-in connection. The engaging part engages with the mounting ear plug engaging groove. A nut is sandwiched between the top of the mounting ear plug and the top and bottom surfaces of the panel mounting ear.

[0004] Existing smart switch and socket junction box structures mostly rely on a moisture-proof coating on the outside of the box to ensure its moisture resistance. However, this coating is prone to damage during installation, and there are large gaps at the wire harness insertion points. The junction box of a smart switch and socket contains conductive components such as circuit boards and metal terminals. In high-humidity environments such as bathrooms and kitchens, moisture seeping into the walls can cause short circuits, electrical leaks, and even fire hazards. At the same time, moisture accelerates the oxidation and corrosion of metal terminals, leading to problems such as poor contact and overheating. Therefore, there is an urgent need to propose a corresponding junction box structure for smart switches and sockets to solve the above problems. Summary of the Invention

[0005] The purpose of this invention is to provide a concealed box structure for intelligent switch sockets in order to solve the above-mentioned problems.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] The intelligent switch socket uses a recessed box structure, including a box body. The top of the box body has a wire inlet, and below the wire inlet is a guide seat that is fixedly connected to the inner surface of the top of the box body. The guide seat has an L-shaped structure. The open end of the guide seat integrates a sealing plate and an installation structure for detachable connection of the sealing plate. The sealing plate includes a first part and a second part. The opposing surfaces of the first part and the second part each have multiple sets of half holes, and the opposing surfaces of the first part and the second part each have a sealing gasket fixedly connected.

[0008] Preferably, a retaining edge is fixedly connected to one horizontal side of the box body, and a protruding strip is fixedly connected to the other side of the box body, the protruding strip engaging with the retaining edge.

[0009] Preferably, a locking rod 1 is inserted inside the card edge, and the locking rod 1 is fixedly connected to the outer wall of the box body through a screw hole 1. A locking rod 2 is inserted inside the protrusion, and the locking rod 2 is fixedly connected to the outer wall of the box body through a screw hole 2.

[0010] Preferably, multiple sets of screw holes one and screw holes two are provided, and the multiple sets of screw holes one and screw holes two are distributed in a vertical straight line.

[0011] Preferably, a sealing ring is fixedly connected to the open end of the guide seat, and the front end face of the sealing ring abuts against the rear end face of the sealing plate.

[0012] Preferably, both the outer walls of the first and second parts are fixedly connected with mounting plates, and the two sets of mounting plates are respectively fixedly connected to the outer walls of the guide seat via fixing rods.

[0013] Preferably, the split body has a plug plate fixedly connected to its bottom, and the outer wall of the plug plate is inserted into the interior of the split body through a slot.

[0014] A method of using a recessed box structure for a smart switch socket includes the following steps:

[0015] Step 1: Combine Split 1 and Split 2 and place them on the outside of multiple sets of external wires. The sealing gasket ensures the airtightness between Split 1, Split 2 and the wire harness.

[0016] Step 1: Next, move the overall sealing plate to make it abut the open end of the guide seat;

[0017] Step 3: By cooperating with the corresponding mounting plate and fixing rod, the first and second parts are fixed to the guide seat. At this time, the sealing ring ensures the airtightness between the sealing plate and the guide seat.

[0018] A method for manufacturing a concealed box structure for a smart switch socket includes the following steps:

[0019] S1. Raw material preparation: Prepare raw materials by weight, including 70-80 parts of high-impact ABS resin, 5-8 parts of nano-grade montmorillonite powder, 1-2 parts of silane coupling agent, 0.5-1 part of polyethylene glycol antistatic agent, 3-5 parts of maleic anhydride grafted ABS compatibilizer, and 4-6 parts of environmentally friendly flame retardant.

[0020] S1. Mold pretreatment: Clean the mold cavity with high temperature and high pressure steam to remove residual oil stains, and apply high temperature resistant mold release agent after drying;

[0021] S2. Surface modification of nano-montmorillonite powder: Place nano-sized montmorillonite powder in an oven at 100-110℃ and dry for 2 hours. After cooling to room temperature, mix with silane coupling agent and place in a high-speed mixer and stir at 800-1000r / min for 15 minutes to obtain surface-modified montmorillonite powder.

[0022] S3. Preparation of ABS moisture-proof modified material: High-impact ABS resin, surface-modified montmorillonite powder, polyethylene glycol antistatic agent, maleic anhydride grafted ABS compatibilizer, and environmentally friendly flame retardant are sequentially fed into the hopper of a twin-screw extruder. The extruder is started for melt blending. After the extruded material is cooled in a cooling water tank, it is cut into particles with a particle size of 3-5mm by a pelletizer, which is the ABS moisture-proof modified material.

[0023] S4. Drying the modified material: Place the ABS moisture-proof modified material in an 80-90℃ drying oven and dry for 3-4 hours, stirring once every 1 hour during the process to ensure uniform drying;

[0024] S5. Injection Molding: The dried modified material is put into the barrel of the injection molding machine, the injection molding machine is started for preheating, and after the temperature stabilizes, the injection molding program is started. After the modified material is melted, injected, held under pressure and cooled, the mold is opened and the box blank is taken out, and the gate residue is removed.

[0025] S6. Vacuum moisture-proof curing: Place the blank of the dark box into a vacuum oven, close the oven door and evacuate to -0.08 to -0.1 MPa, raise the temperature to 50-60℃, keep it at the temperature for 2 hours, after the temperature is maintained, slowly return the pressure to normal pressure, and take it out after it cools naturally to room temperature.

[0026] Preferably, in step S4, after the ABS moisture-proof modified material is dried, the moisture content of the ABS moisture-proof modified material is detected. If the moisture content is not less than 0.05%, the drying time is extended by 1 hour and the test is repeated.

[0027] In summary, due to the adoption of the above technical solution, the beneficial effects of the present invention are:

[0028] 1. In this application, at the material level, an active moisture-proof design, combining nano-montmorillonite layer barrier and antistatic condensation inhibition, integrates moisture-proof performance into the material itself, solving the technical problem of moisture-proof failure caused by coating peeling. Simultaneously, through compatibilizer-optimized formulation, the addition of moisture-proof fillers ensures the integrity of the ABS material. The material's mechanical strength is balanced with its moisture-proof performance. At the hardware level, the external line enters through the inlet and exits through the guide seat. The L-shaped design of the guide seat ensures the connection area between the sealing plate and the guide seat faces forward, facilitating the installation and removal of the sealing plate. The first and second separate components are combined and fitted onto the outside of multiple sets of external lines. A sealing gasket ensures airtightness between the first and second separate components and the wire harness. Then, the entire sealing plate is moved to abut the open end of the guide seat. The corresponding mounting plates and fixing rods secure the first and second separate components to the guide seat. At this point, the sealing ring ensures airtightness between the sealing plate and the guide seat. This ensures both the quantitative extraction of the external line within the box and the airtightness of the connection area between the external line and the box, keeping the box sealed and preventing moisture intrusion. This prevents moisture penetration and gap intrusion, improving the moisture-proof performance of the junction box and thus enhancing the structural stability of the junction box for intelligent switch sockets.

[0029] 2. In this application, the locking rod one fixes the retaining edge to one side of a set of boxes, and then the locking rod two fixes the protruding strip to the adjacent side of another set of boxes. The combination of the protruding strip and the retaining edge facilitates the splicing of the two sets of boxes to meet the needs of installing multiple sets of boxes side by side. The installation method of the locking rod ensures the convenience of assembling and disassembling the protruding strip and the retaining edge. The combination of the locking rod and multiple sets of screw holes allows the operator to increase or decrease the number of protruding strips and retaining edges according to the installation requirements, thereby improving the ease of use of the concealed box structure for intelligent switch sockets.

[0039] The intelligent switch socket uses a recessed box structure, including a box body 1. The top of the box body 1 has a wire inlet 9. Below the wire inlet 9, there is a guide seat 10 that is fixedly connected to the inner surface of the top of the box body 1. The guide seat 10 has an L-shaped structure. The open end of the guide seat 10 integrates a sealing plate 11 and an installation structure for detachable connection of the sealing plate 11. The sealing plate 11 includes a first part 1101 and a second part 1102. The opposite surfaces of the first part 1101 and the second part 1102 each have multiple sets of half holes, and the opposite surfaces of the first part 1101 and the second part 1102 each have a sealing gasket 15 fixedly connected.

[0040] A method of using a recessed box structure for a smart switch socket includes the following steps:

[0041] Step 1: Combine split body 1101 and split body 2 1102 and put them on the outside of multiple sets of external wires. The sealing gasket 15 ensures the airtightness between split body 1101, split body 2 1102 and the wire harness.

[0042] Step 1: Next, move the overall sealing plate 11 so that it abuts against the open end of the guide seat 10;

[0043] Step 3: The corresponding mounting plate 12 and fixing rod 13 are used to fix the first split body 1101 and the second split body 1102 to the guide seat 10. At this time, the sealing ring 14 ensures the airtightness between the sealing plate 11 and the guide seat 10.

[0044] A method for manufacturing a concealed box structure for a smart switch socket includes the following steps:

[0045] S1. Raw material preparation: Prepare raw materials by weight, including 70-80 parts of high-impact ABS resin, 5-8 parts of nano-grade montmorillonite powder, 1-2 parts of silane coupling agent, 0.5-1 part of polyethylene glycol antistatic agent, 3-5 parts of maleic anhydride grafted ABS compatibilizer, and 4-6 parts of environmentally friendly flame retardant.

[0046] S1. Mold pretreatment: Clean the mold cavity with high temperature and high pressure steam to remove residual oil stains, and apply high temperature resistant mold release agent after drying;

[0047] S2. Surface modification of nano-montmorillonite powder: Place nano-sized montmorillonite powder in an oven at 100-110℃ and dry for 2 hours. After cooling to room temperature, mix with silane coupling agent and place in a high-speed mixer and stir at 800-1000r / min for 15 minutes to obtain surface-modified montmorillonite powder.

[0048] S3. Preparation of ABS moisture-proof modified material: High-impact ABS resin, surface-modified montmorillonite powder, polyethylene glycol antistatic agent, maleic anhydride grafted ABS compatibilizer, and environmentally friendly flame retardant are sequentially fed into the hopper of a twin-screw extruder. The extruder is started for melt blending. After the extruded material is cooled in a cooling water tank, it is cut into particles with a particle size of 3-5mm by a pelletizer, which is the ABS moisture-proof modified material.

[0049] S4. Drying the modified material: Place the ABS moisture-proof modified material in an 80-90℃ drying oven and dry for 3-4 hours, stirring once every 1 hour to ensure uniform drying. After the ABS moisture-proof modified material is dried, test the moisture content of the ABS moisture-proof modified material. If the moisture content is not less than 0.05%, extend the drying time by 1 hour and test again.

[0050] S5. Injection Molding: The dried modified material is put into the barrel of the injection molding machine, the injection molding machine is started for preheating, and after the temperature stabilizes, the injection molding program is started. After the modified material is melted, injected, held under pressure and cooled, the mold is opened and the box blank is taken out, and the gate residue is removed.

[0051] S6. Vacuum moisture-proof curing: Place the blank of the dark box into a vacuum oven, close the oven door and evacuate to -0.08 to -0.1 MPa, raise the temperature to 50-60℃, keep it at the temperature for 2 hours, after the temperature is maintained, slowly return the pressure to normal pressure, and take it out after it cools naturally to room temperature.

[0052] At the material level, an active moisture-proof design, combining nano-montmorillonite layer barrier and antistatic condensation inhibition, integrates moisture-proof performance into the material itself, solving the technical problem of moisture-proof failure caused by coating peeling. Simultaneously, through compatibilizer optimization, the mechanical strength of the ABS material is maintained while adding moisture-proof fillers, balancing material strength and moisture-proof performance. At the hardware level, the external line enters through inlet 9 and exits through guide seat 10. The L-shaped design of guide seat 10 ensures that the connection area between the sealing plate 11 and guide seat 10 faces forward, facilitating the installation and removal of the sealing plate 11. The first and second parts 1101 and 1102 are combined and fitted onto the outside of multiple sets of external lines. The sealing gasket 15 ensures airtightness between the first and second parts 1101, 1102, and the wire harness. Then, the entire sealing plate 11 is moved to abut the open end of the guide seat 10, and the corresponding installation is completed. The cooperation between the mounting plate 12 and the fixing rod 13 fixes the first split part 1101 and the second split part 1102 to the guide seat 10. At this time, the sealing ring 14 ensures the airtightness between the sealing plate 11 and the guide seat 10. This ensures that the external line is quantitatively led out inside the box 1, while also ensuring the airtightness of the connection area between the external line and the box 1. This makes the box 1 closed, preventing the intrusion of moisture. This not only prevents the penetration of moisture and the intrusion of gaps, but also improves the moisture-proof performance of the junction box, thereby improving the stability of the junction box structure for intelligent switch sockets.

[0053] Specifically, such as Figure 2 and Figure 4 As shown, a retaining edge 2 is fixedly connected to one horizontal side of the box body 1, and a protruding strip 3 is fixedly connected to the other side of the box body 1. The protruding strip 3 engages with the retaining edge 2. A locking rod 4 passes through the inside of the retaining edge 2 and is fixedly connected to the outer wall of the box body 1 through a screw hole 7. A second locking rod 6 passes through the inside of the protruding strip 3 and is fixedly connected to the outer wall of the box body 1 through a screw hole 8. Multiple sets of screw holes 7 and 8 are provided, and the multiple sets of screw holes 7 and 8 are vertically distributed. The retaining edge is fixed by the locking rod 4. On one side of a set of boxes 1, the protruding strip 3 is fixed to the adjacent side of another set of boxes 1 by means of locking rod 2 6. The combination of the protruding strip 3 and the retaining edge 2 facilitates the splicing of two sets of boxes 1 to meet the needs of multiple sets of boxes 1 installed side by side. The installation method of the locking rod ensures the convenience of assembling and disassembling the protruding strip 3 and the retaining edge 2. The combination of the locking rod and multiple sets of screw holes allows the operator to increase or decrease the number of protruding strips 3 and retaining edges 2 according to the installation requirements, thereby improving the convenience of using the concealed box structure for intelligent switch sockets.

[0054] Specifically, such as Figure 2 and Figure 3As shown, a sealing ring 14 is fixedly connected to the open end of the guide seat 10. The front face of the sealing ring 14 abuts against the rear face of the sealing plate 11. The sealing ring 14 ensures the airtightness between the sealing plate 11 and the guide seat 10. Mounting pieces 12 are fixedly connected to the outer walls of both the first split body 1101 and the second split body 1102. The two sets of mounting pieces 12 are fixedly connected to the outer walls of the guide seat 10 through fixing rods 13, thereby ensuring the ease of assembly and disassembly of the first split body 1101 and the second split body 1102. An insert piece 16 is fixedly connected to the bottom of the first split body 1101. The outer wall of the insert piece 16 is inserted into the inside of the second split body 1102 through a slot 5, thereby enabling the quick alignment of the first split body 1101 and the second split body 1102.

The sealing gasket 15 ensures the airtightness between the first split element 1101, the second split element 1102, and the wire harness. Then, the entire sealing plate 11 is moved to abut the open end of the guide seat 10. The corresponding mounting piece 12 and the fixing rod 13 secure the first split element 1101 and the second split element 1102 to the guide seat 10.

The airtightness of the connection area between the external line and the box 1 ensures that the box 1 is sealed, preventing moisture intrusion. This not only prevents moisture penetration and gap intrusion but also improves the moisture-proof performance of the junction box, thereby enhancing the stability of the junction box structure for smart switch sockets. The locking rod 4 fixes the clip to one side of a set of boxes 1, and then the locking rod 6 fixes the protrusion 3 to the adjacent side of another set of boxes 1. The combination of the protrusion 3 and the clip 2 facilitates the splicing of two sets of boxes 1 to meet the needs of installing multiple sets of boxes 1 side by side.
