Description
Technical Field
[0001] The utility model belongs to the technical field of junction boxes, and particularly relates to a new type of junction box for color steel plate walls. Background Art
[0002] The junction box is one of the electrical accessories. Since the wires used in decoration pass through the wire pipes, at the joint parts of the wires (such as when the line is relatively long or the wire pipe needs to turn a corner), the junction box is used as a transition. The wire pipe is connected to the junction box, and the wires inside the pipe are connected in the junction box, playing the role of protecting the wires and connecting the wires.
[0003] Currently, in many clean workshops such as pharmaceutical and electronic factories, installing junction boxes in color steel plate walls is both time-consuming and laborious. As Figures 1 to 5 shown, the specific operations are as follows:
[0004] 1) Measurement and marking: Use a tape measure and a pencil to accurately measure and mark the positions and sizes of two holes on the color steel plate. The size of hole 1 is the same as the outer size of the junction box. The upper and lower sides of hole 2 are each reduced by 10 mm inward compared to the upper and lower sides of hole 1. Then, mark the positions 10 mm inward on the upper and lower lines of hole 2. Connect the four marked points of hole 2 to the four points of hole 1 respectively, as Figure 1 shown.
[0005] 2) Select appropriate tools: Select appropriate hole-opening tools according to the thickness and material of the color steel plate, such as an electric drill with a suitable drill bit, or a special metal cutting tool.
[0006] 3) Safety protection: Before starting the operation, wear personal protective equipment, such as safety glasses, dust masks, and gloves, to protect yourself from harm and dust.
[0007] 4) Hole opening: Operate the tool steadily and slowly, and cut along the path of the bold line, as Figure 2 shown. Keep your hand steady to avoid the drill bit shifting, resulting in irregular or oversized holes.
[0008] 5) Clean the hole: After hole opening, use a vacuum cleaner or a brush to clean the debris and dust around the hole to ensure the installation surface is clean.
[0009] 6) Install the junction box: Fold the first color steel plate 3 and the second color steel plate 4 in Figure 2 outward to be perpendicular to the wall, as Figure 3 shown; then place the junction box in the hole, as Figure 4 shown; then press the first color steel plate 3 and the second color steel plate 4 inward by 180°, as Figure 5As shown, it is fixed with screws. Ensure that the junction box is firmly and horizontally installed for easy access and management of wires.
[0010] 7) Wiring and Sealing: Conduct wiring according to the circuit design and properly handle the connection of each wire with insulating tape or wire connectors; finally, use sealant or a suitable sealing plate to seal the gap between the periphery of the junction box and the color steel plate to prevent dust and moisture from entering.
