Description

TECHNICAL FIELD

[0001] The utility model relates to control box accessory technical field, concretely is a wiring structure of control box. BACKGROUND

[0002] The crossbeam of the control cabinet plays an important role in the electrical system, and is usually called "bus slot support" or "supporting crossbeam". Its main function is to support and fix electrical components such as bus slot and cable bridge. These electrical components are the key part of energy transmission and distribution in the electrical system. Through the stable support of the crossbeam, the loosening or falling caused by vibration or external force can be effectively prevented, thereby ensuring the stable operation of the electrical system.

[0003] At present, the crossbeam in the control cabinet on the market does not have the function of facilitating wiring. When the wire in the control cabinet is BVR wire, the BVR wire is a multi-core flexible wire composed of multiple thin copper wires, so it feels soft and is easy to bend and install, especially suitable for complex wiring environment. However, while this softness brings convenience in installation, due to its "soft" characteristics, the wire may rub against the crossbeam in the control cabinet, causing wear or local high temperature. As a result of friction and aging of the insulation material, local discharge and short circuit may occur, thereby causing safety accidents. CONTENT OF THE UTILITY MODEL

[0004] The utility model aims at providing a wiring structure of control box, which can effectively support the "soft" wire in the control box, facilitate smooth wiring operation, and prevent the wire from rubbing against the crossbeam, thereby improving the safety performance during the subsequent operation of the control cabinet to solve the problems raised in the above background technology.

[0005] To achieve the above-mentioned purpose, the utility model provides the following technical scheme: a wiring structure of control box, comprising a crossbeam, an electrical component is installed in front of the crossbeam, a wire is connected to the wiring end of the electrical component, a wiring assembly is connected to the wire, the wiring assembly comprises: two convex barrels, the two convex barrels are respectively located on both sides of the rear surface of the crossbeam, first bolts are inserted into both sides of the front surface of the crossbeam, a part of the first bolts penetrates the crossbeam and the convex barrel in sequence, support rods are fixedly connected to the outer wall of the convex barrel at the top and bottom ends, second bolts are threadedly connected to the outer wall of the support rods, the part of the second bolts penetrating the support rods is threadedly connected with square rods, a plurality of square barrels are sleeved on the outer wall of the square rods, third bolts are threadedly connected to the top end of the square barrels, the part of the third bolts penetrating the square barrels is threadedly connected with the square rods, U-shaped clamps are arranged on the side of the square barrels close to the wire, and support cross rods are fixedly connected between the U-shaped clamps and the square barrels.

[0006] Preferably, a scale is arranged on the front surface of the square rod in the transverse direction.

[0007] Preferably, a plurality of anti-slip balls are fixed to the inner surface of the U-shaped card, and the anti-slip balls are pressed against the outer wall of the wire.

[0008] Compared with the prior art, the beneficial effects of this utility model are: the wiring structure of the control box has the following advantages over traditional technology:

[0009] By coordinating the beam, electrical components, wires, and wiring assemblies, the electrical components can be installed on the front of the beam after it is installed inside the control box. After the electrical components are connected to the wires, the operator rotates the third bolt counterclockwise to create a gap between it and the square rod. Then, lateral force is applied to the square tube to make it slide on the outer wall of the square rod. After the U-shaped clip comes above the wire, the third bolt is rotated clockwise to position the square tube. Then, the U-shaped clip can be fitted onto the outside of the wire, which can effectively support the "soft" wires in the control box, making it easy to run the wiring smoothly and preventing friction between the wires and the beam, thus improving the safety performance of the control cabinet during subsequent operation.

[0010] By coordinating the crossbeam, electrical components, wires, wiring assemblies, anti-slip balls, and scales, the position of the sliding square tube on the outer wall of the square rod can be adjusted relatively accurately by observing the positional relationship between the square tube and the scale. The anti-slip balls increase the frictional resistance of the inner surface of the U-shaped clip, which can increase the stability of the wires and U-shaped clips after they are fitted together.
