Description

Technical Field

[0001] The utility model relates to the technical field of bus duct plug-in, and more specifically, to a plug-in box for a bus duct. Background Art

[0002] The plug-in box is equivalent to a cable branch box, which is used for cable tapping or transfer, and mainly plays the role of cable tapping and cable transfer. With the development of the cableization process of the distribution network, when the independent load with small capacity is distributed more concentratedly, a cable branch box can be used to connect multiple branches of the cable, because the branch box cannot directly operate each line. The cable tapping function, when there are multiple small-area cables on a line with a relatively long distance, it often causes a waste of cable use. Therefore, when the line is connected to the power load, the trunk large cable is often used for the line, and then when it is close to the load, the cable branch box is used to divide the trunk cable into several small-area cables, and the small-area cables are connected to the load.

[0003] For example, a bus duct switch plug-in box disclosed in authorization announcement No. CN 220086917 U can facilitate workers to install and disassemble the bus duct by setting limit blocks, limit grooves, slide grooves and sliders, and the clamping connection between the limit blocks and the limit grooves can ensure the stable operation of the bus duct, making the maintenance of the bus duct simple and easy to operate, effectively solving the problem of inconvenient maintenance of existing bus duct plug-in boxes, further reducing the safety hazards during the operation of the bus duct, and achieving the effect of facilitating the maintenance of the bus duct; the wires can be fixed by setting wiring holes, a first arc-shaped clamp and a second clamp, effectively preventing the wires from loosening when the workers install and pull the wires, making the wires more firm and reliable in the box, achieving the effect of improving the stability of the wires.

[0004] In the above scheme, the box door is separated from the box body by pulling, so that the box door and the box body are quickly separated. However, the fixation between the box door and the box body only relies on the clamping connection between the limit block and the limit groove to fix the box door and the box body. A spring is provided on the end face of the limit block. When the limit block is squeezed, the spring will contract, affecting the stability of the connection between the box door and the box body, posing a safety hazard. Utility Model Content

[0024] like Figures 1 to 5 As shown,

[0025] The plug-in box for bus duct comprises a box body 1 and a box door 2. The box body 1 has a cavity 3 inside for installing cables. The box body 1 is provided with a wire hole 4 connected with the cavity 3 for easy cable outlet.

[0026] Two connecting holes 5 are symmetrically provided on the side wall of the box door 2, and the connecting holes 5 pass through the box door 2. A mounting plate 6 is provided on one side of the box door 2, and the cable can be installed on the mounting plate 6. The mounting plate 6 is placed between the two connecting holes 5. A docking hole 7 is provided on the outer wall of the box body 1 corresponding to the connecting hole 5. A fixing rod 8 is provided in the connecting hole 5, and the box door 2 is fixed to the box body 1 by the fixing rod 8.

[0027] The fixing rod 8 includes a mounting head 9, a rod body 10 and a fixing head 11 which are connected in sequence. The fixing head 11 is elastic. A through hole 12 is provided on the rod body 10. A clamping piece is provided in the docking hole 7. The clamping piece includes a gasket 13 and an elastic sheet 14. The outer wall of the gasket 13 abuts against the inner wall of the docking hole 7. A clamping groove 15 is provided on the gasket 13 for the fixing rod 8 to pass through. Two elastic clamping nozzles 16 symmetrical about the clamping groove 15 are provided on one end surface of the elastic sheet 14. A fixing groove 17 for the fixing head 11 to pass through is provided between the two elastic clamping nozzles 16 so that the elastic clamping nozzle 16 can fix the fixing head 11 when it passes through.

[0028] The fixing head 11 is anchor-shaped, and the end of the fixing head 11 is arc-shaped. The fixing head 11 includes a main body and a convex tooth 18. The convex tooth 18 abuts against the elastic clamping mouth 16. When the fixing head 11 passes through the fixing groove 17, an extrusion force is formed on the elastic clamping mouth 16 to separate the two elastic clamping mouths 16 so that the fixing head 11 passes between the two elastic clamping mouths 16. An anti-slip sheet is adhered to the end surface of the elastic clamping mouth 16 to increase the friction between the elastic clamping mouth 16 and the fixing head 11.

[0029] A threaded hole penetrating the docking hole 7 is formed on the outer wall of the box body 1 , and a screw is arranged in the threaded hole.
