Description
Technical Field
[0001] This utility model relates to the field of low-voltage box technology, and in particular to a low-voltage box for wiring in low-voltage engineering. Background Technology
[0002] Low-voltage wiring boxes are indispensable devices in home and building intelligent systems. They are used to centrally manage low-voltage wiring for television, telephone, network, security, etc. They have good protective performance, effectively preventing dust, moisture, and electromagnetic interference. They are also easy to maintain and upgrade later, laying the foundation for building a stable and efficient low-voltage system.
[0003] Existing technologies, such as the utility model with publication number CN214069264U, relate to the field of low-voltage boxes, specifically a low-voltage box structure for IoT low-voltage engineering that facilitates wiring. The structure includes a box body with a wire hole on the back. Two symmetrically arranged support blocks are fixedly connected to the inner walls of both sides of the box body, and a support rod is fixedly connected between the two support blocks. Two fixing plates are provided inside the box body, with both ends of the fixing plates slidably sleeved on the support rod. Threaded rods are provided on opposite sides of the two fixing plates, with both ends of the threaded rods rotatably connected to the support blocks. A knob is fixedly sleeved on the threaded rod, and a moving block is threadedly sleeved at both ends of the threaded rod. This utility model facilitates wiring inside the low-voltage box and simultaneously secures the cables to prevent damage from pulling, solving the problem of inconvenient installation and wiring in existing low-voltage boxes.
[0004] However, most existing low-voltage boxes place the wires inside, which can easily lead to wire tangling. In addition to breakage, tangled and knotted wires may also damage the insulation layer. When the wires are squeezed and rubbed against each other, the insulation layer may be damaged or worn. Once the insulation layer is damaged, the internal live conductors will be exposed. If they come into contact with other conductors, leakage will occur. Utility Model Content
[0005] The purpose of this utility model is to solve the problem that in the existing technology, most low-voltage boxes place the wires inside, which easily leads to wire tangling. In addition to breakage, tangling and knotting of wires may also damage the insulation layer of the wires. When the wires are squeezed and rubbed against each other, the insulation layer may be damaged or worn. Once the insulation layer is damaged, the internal live conductors will be exposed. If they come into contact with other conductors, leakage will occur. Therefore, this utility model proposes a low-voltage box for wiring in low-voltage engineering.
[0006] To achieve the above objectives, this utility model adopts the following technical solution: a low-voltage electrical box for wiring in low-voltage engineering, comprising an electrical box and a protective device. A box door is rotatably connected to the surface of the electrical box. Wires are installed inside the electrical box. A floor is installed on the lower surface of the electrical box. The protective device includes a wire rack, which is fixedly connected to the inner wall of the electrical box. Through holes are opened on the surface of the wire rack, and the wires are inserted into these through holes. A wire-passing hole is opened on the side of the electrical box near the wires. A fixing sleeve is fixedly connected to the side of the electrical box near the wires, and Velcro is fixedly connected to the surface of the fixing sleeve. By setting up the protective device, from wire fixing to leakage protection, the reliability and stability of the electrical box are improved. An orderly wiring layout reduces faults caused by wiring problems. An effective leakage protection mechanism ensures the safe operation of the electrical box under abnormal conditions, extends the service life of the electrical box and its internal equipment, and reduces maintenance costs and equipment replacement frequency.
[0007] Preferably, the fixing sleeve is semi-circular, and the Velcro is attached to the fixing sleeve. By setting the Velcro, the wires are separated after passing through the through hole, and then the Velcro is used to fix the wires to the fixing sleeve. This can effectively restrict the movement of the wires in the electrical box, ensuring that each wire is in its proper position and avoiding problems such as wire tangling or knotting caused by the wires shaking or shifting. This keeps the wiring inside the electrical box neat and orderly, facilitating subsequent maintenance and management.
[0008] Preferably, there are two wire frames, which are symmetrically arranged, and the fixing sleeve is located at the center of the two wire frames.
[0009] Preferably, a current guide wire is fixedly connected to the lower surface of the electrical box, and a knob is rotatably connected to the lower surface of the current guide wire. By setting the current guide wire, the current can flow along the current guide wire instead of randomly running around in the electrical box, thus avoiding unnecessary damage to other components in the electrical box.
[0010] Preferably, a bolt is fixedly connected to the lower surface of the knob, and a screw sleeve is fixedly connected to the upper surface of the floor. By setting the bolt, a good electrical connection between the bolt and the screw sleeve can be ensured, and the resistance is small, so that the leakage current can be smoothly transmitted from the drain wire to the screw sleeve and then into the ground.
[0011] Preferably, the bolt is threaded to the sleeve, and the surface of the knob is provided with anti-slip texture.
[0012] Preferably, a rubber pad is fixedly connected to the side of the floor near the screw sleeve. Both the bolt and the screw sleeve are made of iron. By setting the rubber pad, when the wire breaks and the current reaches the screw sleeve through the drain wire and is conducted to the ground, the rubber pad can prevent the current from spreading to other unexpected parts of the electrical box. This avoids electric shock accidents caused by construction personnel coming into contact with accidentally energized parts when repairing the electrical box, thereby ensuring the personal safety of the construction personnel.
[0013] Compared with the prior art, the advantages and positive effects of this utility model are as follows:
[0014] In this invention, when installing electrical wires, the electrical box is fixed to the wall. Then, the wires are inserted into the electrical box through the wire hole and pass through the through hole, where the through hole separates the wires. Then, Velcro is used to fix the wires to the fixing sleeve to prevent loosening. When the wire breaks, the current diffuses in the electrical box and reaches the screw sleeve through the drain wire. Then, it is conducted to the ground through the screw sleeve. The current is isolated by the rubber pad, which reduces the possibility of electric shock for construction workers during maintenance and increases the safety of the electrical box.
[0015] By incorporating this utility model, from fixing the wires to leakage protection, the reliability and stability of the electrical box are improved. The orderly wiring layout reduces the occurrence of faults caused by wiring problems, and the effective leakage protection mechanism ensures the safe operation of the electrical box under abnormal conditions, extends the service life of the electrical box and its internal equipment, and reduces maintenance costs and equipment replacement frequency.

[0022] Please see Figures 1-5 This utility model provides a technical solution: a low-voltage box 1 for wiring in low-voltage engineering, including a box 1 and a protective device 4, a box door 2 rotatably connected to the surface of the box 1, wires 3 installed inside the box 1, and a floor 5 installed on the lower surface of the box 1.
[0023] In this implementation scheme: the protective device 4 includes a wire frame 41, which is fixedly connected to the inner wall of the electrical box 1. The surface of the wire frame 41 has a through hole 49, and the wire 3 is inserted into the through hole 49 on the surface of the wire frame 41. The side of the electrical box 1 near the wire 3 has a wire hole 410. A fixing sleeve 42 is fixedly connected to the side of the electrical box 1 near the wire 3. Velcro 43 is fixedly connected to the surface of the fixing sleeve 42. By setting up the protective device 4, from the fixing of the wire 3 to leakage protection, the reliability and stability of the electrical box 1 are improved. The orderly wiring layout reduces the occurrence of faults caused by wiring problems. The effective leakage protection mechanism ensures the safe operation of the electrical box 1 under abnormal conditions, extends the service life of the electrical box 1 and its internal equipment, and reduces maintenance costs and equipment replacement frequency.
[0024] Specifically, the fixing sleeve 42 is semi-circular, and the Velcro 43 is attached to the fixing sleeve 42. By setting the Velcro 43, the wire 3 is separated after passing through the through hole 49. The Velcro 43 is used to fix the wire 3 to the fixing sleeve 42, which can effectively restrict the movement of the wire 3 in the electrical box 1. This can ensure that each wire 3 is in its proper position and avoid problems such as wire tangling or knotting caused by the wire 3 shaking or shifting at will. This keeps the wiring inside the electrical box 1 neat and orderly, which is convenient for subsequent maintenance and management.
[0025] Specifically, there are two wire frames 41, which are arranged symmetrically, and the fixing sleeve 42 is located at the center of the two wire frames 41.
[0026] Specifically, a current guide wire 45 is fixedly connected to the lower surface of the electrical box 1, and a knob 48 is rotatably connected to the lower surface of the current guide wire 45. By setting the current guide wire 45, the current can flow along the current guide wire 45 instead of randomly running around in the electrical box 1, thus avoiding unnecessary damage to other components in the electrical box 1.
[0027] Specifically, the lower surface of the knob 48 is fixedly connected to a bolt 46, and the upper surface of the floor 5 is fixedly connected to a threaded sleeve 47.
[0028] In this embodiment: by setting the bolt 46, a good electrical connection with the threaded sleeve 47 can be ensured, and the resistance is small, so that the leakage current can be smoothly transmitted from the lead wire 45 to the threaded sleeve 47 and then conducted to the ground.
[0029] Specifically, bolt 46 is threadedly connected to sleeve 47, and the surface of knob 48 is provided with anti-slip texture.
[0030] Specifically, a rubber pad 44 is fixedly connected to the side of the floor 5 near the screw sleeve 47, and both the bolt 46 and the screw sleeve 47 are made of iron.
[0031] In this embodiment: by setting a rubber pad 44, when the wire 3 breaks and the current reaches the screw sleeve 47 through the drain wire 45 and is introduced into the ground, the rubber pad 44 can prevent the current from spreading to other unexpected parts of the electrical box 1, thus avoiding electric shock accidents caused by contact with accidentally energized parts when the construction personnel are repairing the electrical box 1, thereby ensuring the personal safety of the construction personnel.
[0032] Working principle: When installing wire 3, the electrical box 1 is fixed to the wall. Then, wire 3 enters the electrical box 1 through the wire hole 410 and passes through the through hole 49. At this time, the through hole 49 separates the wire 3. Then, Velcro 43 is used to fix the wire 3 to the fixing sleeve 42 to prevent loosening. When wire 3 breaks, the current diffuses in the electrical box 1 and reaches the screw sleeve 47 through the drain wire 45. Then, it is led to the ground through the screw sleeve 47. The rubber pad 44 isolates the current, reducing the possibility of electric shock for construction personnel during maintenance and increasing the safety of the electrical box 1. By setting up this utility model, from the fixing of wire 3 to leakage protection, it helps to improve the reliability and stability of the electrical box 1. The orderly circuit layout reduces the occurrence of faults caused by circuit problems. The effective leakage protection mechanism ensures the safe operation of the electrical box 1 under abnormal conditions, extends the service life of the electrical box 1 and its internal equipment, and reduces maintenance costs and equipment replacement frequency.
