[0002] With the development of the Internet of Things technology, more and more electrical appliances are installed, and the use of supporting switchgears also becomes more. Before power transmission, the switchgear is used to pass in the cable and fix the cable end head on the wiring terminal by using alloy pins. The connected cable needs to be arranged in rows and is generally bound by a ribbon.

[0003] Among them, the wiring terminal is usually assembled into the switchgear by using screws in the factory, and wire insertion holes are reserved on the upper and lower surfaces of the wiring terminal to facilitate the insertion of the cable end head.

[0004] In the wiring process, part of the high-voltage cable is thick and heavy, and is generally supported by adding a clamping plate, but the reserved hole of the clamping plate is vertical and cannot support the high-voltage cable in advance, so that the worker not only needs to hold the high-voltage cable with one hand, but also needs to reinforce the clamping plate with the other hand, which is time-consuming and laborious.

DETAILED DESCRIPTION

[0023] In order to make the purpose and the advantage of the utility model more clearly and clearly, the utility model is specifically explained below with examples. It should be understood that the following text is only used to describe one or several specific embodiments of the utility model, and does not strictly limit the protection scope of the utility model specifically requested.

[0024] For example, Figures 1-4As shown, a wiring device for a distribution cabinet, suitable for high-voltage distribution cabinets, includes terminal blocks 1 that can be arranged side by side. Vertically arranged outside the terminal blocks 1 are a back plate 2, a crossbeam 3 connected to the bottom of the back plate 2, a suspension rod 4 connected to the bottom surface of the back plate 2, and an insulating support 5 connected to the bottom of the suspension rod 4. During factory processing, the back plate 2, crossbeam 3, and suspension rod 4 are integrally manufactured, providing high support strength. The insulating support 5 is then fixed to the lower end of the suspension rod 4 with bolts. Since the top surface of the crossbeam 3 contacts the bottom surface of the terminal blocks 1, during assembly, the terminal blocks 1 are first attached to the front of the back plate 2 along the top surface of the crossbeam 3, and then fixed together to the inside of the high-voltage distribution cabinet with screws. Upon arrival at the site, the high-voltage distribution cabinet can be installed. The high-voltage cable is then inserted into the wall. In this embodiment, an arc-shaped cable-laying groove 6 is provided on one side of the insulating support 5. The high-voltage cable can be inserted into the cable-laying groove 6 at a fixed length for suspension support without the need for hand support. Then, in this embodiment, a handle bolt 8 is threaded on the outside of the insulating support 5, spaced apart from the cable-laying groove 6. The handle bolt 8 can be reversed to disengage from the insulating support 5. For the placed high-voltage cable, the insulating support 5 is connected to a cover 7 through the handle bolt 8. The cover 7 covers the cable-laying groove 6, and the handle bolt 8 is turned forward to tighten the insulating support 5, achieving quick capping and locking the position of the high-voltage cable at that point. This frees up both hands, making it convenient to use a knife to peel off the end of the high-voltage cable and insert it into the insertion groove of the terminal 1.

[0025] See attached document Figure 1 and Figure 2 In this embodiment, a hollow groove 201 is provided in the middle of the back plate 2 to reduce the counterweight. A positioning rake tooth 202 parallel to the top surface of the terminal 1 is welded to the top of the back plate 2. The positioning rake tooth 202 is used in conjunction with the crossbeam 3 to clamp the terminal 1 from both sides, so that the back plate 2 and the terminal 1 can be more closely connected.

[0026] See attached document Figure 1 , Figure 2 and Figure 3 Furthermore, a wire mesh 401 and a first through-pin ear plate 402 are welded at intervals on the outside of the suspension rod 4. Since the two ends of the wire mesh 401 are respectively connected to the bottom of the crossbeam 3 and the top of the insulating support 5, the internal firmness of the wiring device can be further improved. Screws can also be passed through the first through-pin ear plate 402 and fixed to the inner wall of the high-voltage distribution box.

[0027] See attached document Figure 2 and Figure 3To better protect the high-voltage cable, this embodiment has damping strips 601 bonded to both sides of the cable tray 6, spaced apart from the cover 7, and anti-cut pads 602 bonded to the other two sides. When inserted, these pads separate the high-voltage cable from the edge of the cable tray 6. The anti-cut pads 602 have an arc that fits the cable, which can support the high-voltage cable well. When the high-voltage cable is forced to push the damping strips 601 apart, it can be inserted into the cable tray 6. In this way, the damping strips 601 can effectively limit the high-voltage cable and prevent it from falling, allowing sufficient time for the cover 7 to be installed.

[0028] See attached document Figure 1 , Figure 2 and Figure 3 The insulating base 5 has a second through-bolt ear plate 603 welded on both sides and a reinforcing rib plate 604 welded together with the second through-bolt ear plate 603. It can be fixed to the inner wall of the high-voltage distribution box by screws passing through the second through-bolt ear plate 603. There is a gap between the reinforcing rib plate 604 and the cover 7 so as not to obstruct the addition of the cover.

[0029] See attached document Figure 1 and Figure 4 The outer surface of the cover 7 is welded with reinforcing ribs 701 and hand support parts 702 at intervals. When the cover is put on, there is no interference between the hand support parts 702 and the handle bolt 8 because there is a gap. The two hand support parts 702 can be pinched with two fingers respectively to move the cover 7 conveniently. After the cover is put on, the reinforcing ribs 701 can be used to increase the support strength of the cover 7.

[0030] See attached document Figure 1 and Figure 4 The cover 7 has a glass observation window 703 running through the middle, which allows the view through the glass observation window 703 to observe the high-voltage cable during subsequent maintenance. The handle is supported by a washer 801 that contacts the cover 7 and is fitted on the outside of the handle bolt 8, preventing the handle from directly rubbing against the cover 7 when it is turned.

[0031] The working principle of this utility model is as follows: During factory processing, the back plate 2, the crossbeam 3 and the suspension rod 4 are integrated into one piece, providing high support strength. The insulating seat 5 is then fixed to the lower end of the suspension rod 4 with bolts. During assembly, the wiring terminal 1 is first attached to the front of the back plate 2 along the top surface of the crossbeam 3, and then fixed together with screws to the inside of the high-voltage distribution cabinet. After arriving at the site, the high-voltage distribution cabinet is installed on the wall, and then the high-voltage cable is inserted. The fixed length of the high-voltage cable is inserted into the cable tray 6 for suspension support, without the need for manual support.

[0032] Then, reverse the handle bolt 8 to disengage from the insulating support 5. For the high-voltage cable that has been placed, cover the cable tray 6 with the cover 7 and tighten the insulating support 5 with the forward handle bolt 8 to quickly cover and lock the position of the high-voltage cable, freeing up both hands to facilitate the subsequent stripping of the high-voltage cable end with a knife and insertion into the insertion slot of the terminal 1.

[0033] The above description is merely an optional embodiment of this utility model. It should be noted that those skilled in the art can make various improvements and modifications without departing from the principle of this utility model, and these improvements and modifications should also be considered within the scope of protection of this utility model. Structures, devices, and operating methods not specifically described or explained in this utility model, unless otherwise specified or limited, shall be implemented according to conventional methods in the field.
