Description

Technical Field

[0001] This utility model relates to the field of junction box technology, and in particular to a detachable power junction box structure. Background Technology

[0002] Junction boxes are one of the electrical accessories. Because the wires used in decoration run through conduits, junction boxes are used as transitions at the joints of the wires (such as when the wire is long or the conduit needs to turn a corner). The conduit connects to the junction box, and the wires inside the conduit are connected in the junction box, which serves to protect and connect the wires. This is what a junction box is.

[0003] Chinese Patent No. CN213753894U discloses a junction box for power installation, including a protective outer shell. A sealing plate is fixed to the upper surface of the protective shell. An inner junction box is installed inside the protective shell. A first inlet / outlet conduit is welded through one side of the inner junction box, and a second inlet / outlet conduit is welded through the other side. Sealing end sleeves are installed at one end of the outer surfaces of both the first and second inlet / outlet conduits. A heat dissipation plate is provided on the outer surface of the sealing plate. A fixing groove plate is provided on the inner surface of the protective shell. A capacitor wire is installed inside the inner junction box, and a first terminal is installed at one end of the inner junction box. This utility model's junction box for power installation features a sealed structure, and the outer surface of the device is provided with a heat dissipation copper plate, which is beneficial for use in humid environments. The disassembly structure is relatively simple, and an electric fuse serves as the device's circuit protection structure.

[0004] Existing junction boxes use screws to control the movement of pressure plates, which together clamp the power line ends with the pressure plates and electrical connection plates. However, when the screws become unstable due to vibration, gaps appear at the connection between the screws and the inner junction box. In humid environments, water can easily seep into the inner junction box through these gaps, affecting the connection stability of the power lines inside the junction box. This reduces the functionality of the detachable structure of the junction box and lowers its practicality. Utility Model Content

[0024] The specific embodiments of this disclosure will be described in detail below with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are for illustration and explanation only and are not intended to limit this disclosure.

[0025] Example 1

[0026] like Figure 1 - Figure 3As shown, the present invention proposes a detachable power junction box structure, comprising: a protective shell 1, an assembly assembly, and a wiring assembly; the assembly assembly is connected to the protective shell 1; the assembly assembly includes an L-shaped assembly shell 2, a heat dissipation plate 201, a frame 202, mounting rods 203, adjustment holes 204, positioning blocks a 205 and b 206, mounting screws 207, and a positioning plate 208; heat dissipation plates 201 are respectively provided on both sides of the L-shaped assembly shell 2, and mounting rods 203 are respectively connected to both ends of the positioning plate 208. Each mounting rod 203 passes through the L-shaped assembly shell 2 and is connected to the outer frame 202. Each mounting rod 203 is evenly provided with adjustment holes 204. Positioning blocks a 205 and b 206 are provided on the L-shaped assembly shell 2 and face the protective shell 1. The mounting screws 207 are used to realize the fixed and detachable connection between the protective shell 1 and the L-shaped assembly shell 2. Two frames 202 are provided at both ends of the upper surface of the L-shaped assembly shell 2; the wiring assembly is connected inside the protective shell 1. The L-shaped assembly housing 2 is made of flame-retardant and fiberglass composite material, which improves impact resistance and also provides insulation. The L-shaped assembly housing 2 and the protective housing 1 can be fixed and disassembled, which facilitates the disassembly of the L-shaped assembly housing 2 for power line wiring operations and improves the usability of the detachable power junction box structure.

[0027] Further explanation: the protective shell 1 is provided with positioning groove a101 and positioning groove b102, and faces the L-shaped assembly shell 2; the protective shell 1 is provided with a reserved threaded hole, and faces the L-shaped assembly shell 2; the L-shaped assembly shell 2 is provided with mounting holes, the mounting holes and the reserved threaded holes are opposite each other and the number is the same; the mounting screw 207 passes through the mounting hole and the reserved threaded hole and is threadedly connected; positioning groove a101 is detachably connected to positioning block b206, and positioning groove b102 is detachably connected to positioning block a205. The inner walls of positioning grooves a101 and b102 are provided with a thick rubber buffer layer, and the groove openings are beveled at a certain angle. When positioning blocks a205 and b206 are fitted together, the rubber layer can fill the assembly gap, avoiding metal wear caused by long-term vibration. At the same time, the beveled design allows the positioning blocks to be quickly inserted, improving assembly alignment efficiency. In addition, the depth of the positioning groove is greater than the insertion depth of the positioning block, ensuring no lateral offset after pre-connection and ensuring precise alignment of the reserved threaded holes and mounting holes. The reserved threaded holes and mounting holes are aligned one by one, and then the mounting screws 207 are used to assemble and install the protective shell 1 and L-shaped assembly shell 2 of the detachable power junction box structure, so as to achieve the protective function of the inner junction box 4 and improve the use effect of the inner junction box 4.

[0028] Example 2

[0029] like Figure 3 As shown, this utility model proposes a detachable power junction box structure. Based on the above embodiments, this embodiment also details the specific components of the wiring assembly and their matching methods.

[0030] Further explanation: The wiring assembly includes an inner junction box 4, inlet / outlet conduits b401, an electrical connection plate 402, terminals 403, capacitor wire 404, a pressure plate 405, and connecting screws 406. The inner junction box 4 is connected to the inlet / outlet conduits b401 at both ends, and the inlet / outlet conduits b401 are connected to the inner wall of the protective shell 1. The electrical connection plate 402 is connected to the terminals 403. The capacitor wire 404 is connected inside the inner junction box 4. The pressure plate 405 is connected to the connecting screws 406. The operating end of the connecting screws 406 passes through the inner junction box 4 and is located inside the protective shell 1. A maintenance plate is provided on the front surface of the inner junction box 4. The electrical connection plate 402, terminals 403, pressure plate 405, and connecting screws 406 are connected to form a wiring fixing unit, and two sets of wiring fixing units are provided. The outer surface of the inner junction box 4 is coated with an epoxy resin moisture-proof coating to form an isolation film, preventing moisture from directly contacting the housing. During use, the heat from the inner junction box 4 is dissipated through the heat sink 201. When an abnormal voltage occurs inside the inner junction box 4, the electrodes are disconnected, completing circuit protection. This allows for the removal of the L-shaped assembly shell 2 for repair of the inner junction box 4. After repair, if there are no abnormalities, it can be used again. When using the wiring assembly, the connection of the L-shaped assembly shell 2 is disassembled. First, the wire ends 403 of the required wiring are clamped with wire cutters. The wire ends 403 of the two wires are then fixed to the sealing end sleeve 5 and the wiring on both sides. The unit connection allows the wire ends to be inserted into the surfaces of the electrical connection plates 402 on the terminals 403 at both ends. Rotating the connecting screws 406 pushes the pressure plates 405 to press and move the wire ends. The electrical connection plates 402 and pressure plates 405 clamp the wire ends, allowing for assembly of the two power wire ends. This structure is built using existing mature technology, so no further details are needed. The protective shell 1 has inlet / outlet conduits a3 connected to both sides. The inlet / outlet conduits a3 at both ends are connected to the inlet / outlet conduits b401 at both ends. Sealing end sleeves 5 are connected to the outer walls of the inlet / outlet conduits a3 at both ends. The sealing end sleeves 5 enhance the performance of the inlet / outlet conduits a3 and improve the practicality of the detachable power junction box structure.

[0031] The working principle of this utility model is as follows: When using the detachable power junction box structure, by disassembling the L-shaped assembly shell 2, the operator connects the power connectors according to the above-mentioned operation. After the connection is completed, the L-shaped assembly shell 2 and the protective shell 1 are connected. At this time, the positioning plate 208 is attached to one side of the inner wall of the L-shaped assembly shell 2 via the mounting support rod 203, allowing the L-shaped assembly shell 2 to move and assemble with the protective shell 1. The L-shaped assembly shell 2 drives the positioning blocks a205 and b206, and the positioning blocks a205 and b102 are engaged. The positioning blocks b206 and a101 are engaged. Through the cooperation of the positioning blocks a205, b206, a101, and b102, the L-shaped assembly shell 2 and the protective shell 1 are pre-connected, thus aligning the reserved threaded holes and mounting holes, facilitating the operation of the mounting screws 207. The mounting screws 207 are used to achieve the connection of the L-shaped assembly shell 2 and the protective shell 1. After the L-shaped assembly shell 2 and the protective shell 1 are fixedly connected, the connection between the mounting rod 203 and the frame 202 is disassembled. The mounting rod 203 is operated to move the positioning plate 208 downward. The positioning plate 208 moves to the upper surface of the connecting screw 406, so that it applies pressure to the connecting screw 406, reducing the impact of vibration on the use of the inner junction box 4 due to the fixing point of the connecting screw 406. After the positioning plate 208 is fixed to the connecting screw 406, the mounting rod 203 is moved close to the upper mounting hole, so that it is aligned with the reserved threaded hole. Then, the height flange bolt and nut are used to cooperate. The bolt passes through the mounting hole and the reserved threaded hole, and the nut thread is locked, thus completing the use of the positioning plate 208. The size of the positioning plate 208 is larger than the size of the inner junction box 4, so that the positioning plate 208 is connected to the inner junction box 4, which provides a waterproof function and facilitates the use of the detachable power junction box structure.

[0032] The embodiments of the present invention have been described in detail above with reference to the accompanying drawings. However, the present invention is not limited thereto. Various changes can be made within the scope of knowledge possessed by those skilled in the art without departing from the spirit of the present invention.
