Description

Technical Field

[0001] The utility model relates to the technical field of junction boxes, in particular to a stainless steel junction box. Background Art

[0002] The junction box is a box used to connect the end user and the network switching equipment. It is usually installed outdoors or indoors and has dust and moisture-proof functions. Various types of interface modules can be installed in the junction box, and the end user can be accessed by inserting the module. The main function of the junction box is to facilitate network maintenance personnel to quickly find and troubleshoot faults and improve the efficiency of network maintenance.

[0003] The traditional junction box has poor protection performance. During use, the junction box will vibrate and may be impacted by external forces, which may cause the interface of the incoming line to loosen. When the interface is loose, the line resistance increases, the wire heats up, and the temperature rises rapidly, which may cause a fire and endanger personal safety. To this end, we proposed a stainless steel junction box. Utility Model Content

[0004] In order to achieve the above-mentioned purpose, the utility model specifically adopts the following technical solutions:

[0005] The lockhole that is formed on the two ends of the support frame is formed on the upper and lower ends of the support frame is fixed with a bolt, and the bolt has a round shank on the bottom end of the support frame are provided with a toothed box, and the toothed box upper and lower ends are provided with a toothed box upper and lower ends.

[0006] Furthermore, the box body is made of stainless steel.

[0007] Furthermore, a plurality of wire fasteners are fixedly connected to the front of the support plate by bolts.

[0008] Furthermore, a mounting plate is fixedly connected to the rear side of the inner wall of the box body by means of bolts.

[0009] Furthermore, a rubber plug is clamped on the inner wall of the wire inlet, and a wiring hole is opened on the top surface of the rubber plug.

[0010] Furthermore, the two telescopic rods each include a cylinder and a rod body, and slide grooves are provided on the left and right sides of the inner walls of the two cylinders. The inner walls of the plurality of slide grooves are slidably connected to the surface of the corresponding rod body through one side of a slider.

[0011] Furthermore, legs are fixedly connected to the four corners of the bottom surface of the box.

[0012] The beneficial effects of the utility model are as follows:

[0013] 1. When using the junction box, when the junction box vibrates or is impacted by external force during use, the connection terminals are not fixed by the telescopic rod, T-rod and connecting rod, so that the incoming line interface is not easily pulled and loosened, and the first spring and the second spring absorb the force generated by vibration and external force impact, so that the connection terminals are not easy to shake excessively, so that the connection of the incoming line interface is more stable, thereby improving the safety of equipment use.

[0014] 2. The stainless steel box has stronger corrosion resistance, higher strength and better quality. The wires connecting the components inside the box are fixed by wire clips, which can prevent the shaking caused by vibration from affecting the wire connections of the components. The mounting plate facilitates the installation of components and improves the practicality of the equipment.

[0015] 3. The rubber plug seals the cable inlet and ensures the access of the wires through the wiring hole. The telescopic rod has telescopic performance and has a limiting effect, which ensures its normal use. The legs make the equipment more stable and avoid the squeezing of the wires caused by the cable inlet touching the ground. BRIEF DESCRIPTION OF THE DRAWINGS
