Description

Technical Field

[0001] This utility model relates to the field of power distribution cabinet technology, and in particular to a power distribution cabinet wiring device. Background Technology

[0002] Distribution cabinet wiring is divided into power distribution cabinet wiring, lighting distribution cabinet wiring, and metering cabinet, and is the final stage equipment of the power distribution system. In distribution cabinet wiring, multiple electrical components need to be connected by cables. In order to arrange the cables in an orderly manner in the distribution cabinet wiring, cable management racks are often installed in the distribution cabinet wiring. By concentrating the cables in the cable management rack, the wiring in the distribution cabinet is kept neat and orderly.

[0003] Chinese utility model CN219554181U discloses a wiring device for a power distribution cabinet. This device uses multiple sets of mounting blocks fixedly installed on the upper surface of a base plate. Two clamping plates between the mounting blocks can clamp and fix cables of different diameters under the action of springs. Simultaneously, multiple sets of cables of the same diameter can be clamped between the two clamping plates, increasing the number of cables that can be clamped and fixed by the device. However, this wiring device for a power distribution cabinet still has the following problems in use:

[0004] The wiring device of the distribution cabinet is clamped left and right by several limiting slots. If the diameter of the cable is smaller than the diameter of the limiting slot, the cable cannot be stably fixed. At the same time, the clamping plate is pushed and clamped by springs, which makes it impossible to adjust the clamping force. Utility Model Content

[0005] The purpose of this invention is to at least solve one of the aforementioned technical defects.

[0006] Therefore, one objective of this utility model is to provide a wiring device for a power distribution cabinet to solve the problems mentioned in the background art and overcome the shortcomings of the existing technology.

[0007] To achieve the above objectives, one embodiment of this utility model provides a wiring device for a power distribution cabinet, including a fixed frame. A plurality of fixed plates are fixedly connected to the inner wall of the fixed frame. A lead screw is fixedly connected to the center of the inner wall of the fixed frame. A plurality of sliding plates are provided on the inner wall of the fixed frame. The bottoms of the sliding plates are slidably connected to the bottom surface of the inner wall of the fixed frame. First guide rods slide through both sides of the fixed plates. Two first guide rods on the same side are fixedly connected to a first clamping block at one end. A plurality of second guide rods slide through the middle of the sliding plates. A second clamping block is fixedly connected to one end of the second guide rods at one end. A clamping block is fixed between two first clamping blocks. The position corresponds to the position of the second clamping block. The distance between the two first clamping blocks is adapted to the thickness of the second clamping block. The end of the first guide bar away from the first clamping block and the end of the second guide bar away from the second clamping block are both fixedly connected to the stop block 6. The outer walls of the first guide bar and the second guide bar are both sleeved with thrust springs. The thrust springs are located between the first clamping block and the fixed plate and between the second clamping block and the sliding plate. A threaded sleeve is rotatably connected to the center of the bottom of the sliding plate. The threaded sleeve is threaded to the lead screw. A nut is fixedly connected to one end of the threaded sleeve. A V-shaped bayonet 5 is opened at the center of the side facing each other of the first clamping block and the second clamping block.

[0008] Preferably, in any of the above embodiments, fixing ear plates are fixedly connected to both sides of the bottom of the fixing frame, and the bottom of the fixing ear plates is lower than the bottom surface of the fixing frame.

[0009] The technical effect achieved by adopting the above solution is that the fixed ear plate makes it easy to install and fix the fixing frame inside the distribution cabinet.

[0010] Preferably, in any of the above embodiments, the plurality of fixed plates are distributed on the inner wall of the fixed frame, the plurality of sliding plates are respectively located between the plurality of fixed plates, and the size of the plurality of sliding plates is equal to the size of the fixed plates.

[0011] The technical effect achieved by adopting the above solution is to ensure that both sides of the fixing frame are flat and neat.

[0012] Preferably, in any of the above solutions, the length of the thrust spring after reset is adapted to the lengths of the first guide bar and the second guide bar, and the diameter of the thrust spring is smaller than the thickness of the first clamping block and the second clamping block.

[0013] The technical effect achieved by adopting the above solution is to prevent the thrust spring from protruding on both sides and interfering with the intersection of the first clamping block and the second clamping block.

[0014] Preferably, in any of the above solutions, the first clamping block and the second clamping block have the same height and the same thickness.

[0015] The technical effect achieved by adopting the above solution is to ensure the flatness of the overall appearance while making the clamping force evenly distributed.

[0016] Compared with the prior art, the advantages and beneficial effects of this utility model are as follows:

[0017] The wiring device of this distribution cabinet can clamp cables of different diameters from the left and right by interlocking first and second clamping blocks and V-shaped bayonet 5. At the same time, the interlocking first and second clamping blocks can hold cables with diameters smaller than the opening width of V-shaped bayonet 5, improving the stability of the fixation. By rotating the threaded sleeve, the sliding plate can be driven to slide, thereby pushing the sliding plate towards the fixed plate, so that the first and second clamping blocks press against each other, and the clamping force can be adjusted.
