Description

Technical Field

[0001] This utility model relates to the field of power cabinet accessories technology, specifically to a wiring device for a power distribution cabinet. Background Technology

[0002] To facilitate operation, some distribution cabinets on the market currently have through-holes in their walls to allow wires to pass through for wiring. However, to facilitate wire pulling, the openings in these cabinets are generally large, resulting in a large allowance between the wire and the opening. After the wire is inserted or removed, the wire or wire end often retracts automatically into the cabinet, or the connected joint slides out of the cabinet. This not only affects the wiring operation and the wiring effect, but also poses safety hazards if the stripped live wire ends spring back into the cabinet or if the uninsulated connection points pop out of the cabinet. Furthermore, after connection, the external wires are pulled by external forces, making the internal connection points prone to loose or broken connections. Utility Model Content

[0003] The technical problem this utility model aims to solve is: addressing the shortcomings in the practical effect of wiring requirements and open-hole structures in distribution boxes, it provides a wiring device for distribution cabinets. This device is installed using a slotted installation method in the cabinet wall and is used in conjunction with existing distribution cabinets. Based on providing a through structure for wires to exit from inside the box and wires to enter from outside the box, it can quickly and temporarily press and fix the wires and wire ends as needed, and provide stable top-tightening fixation. This avoids safety hazards caused by wire ends slipping during operation and malfunctions caused by external pulling after wiring.

[0004] The wiring device of this distribution cabinet includes an insulating wire mounting plate, wherein the wire mounting plate is strip-shaped and has at least one row of wire holes from top to bottom. Several threaded tubes are installed on one side of each wire hole, and a top wire bolt is threaded into each threaded tube. An arc-shaped pressure plate is provided at one end of the threaded tube extending into the wire hole.

[0005] Furthermore, the bolt cap of the top bolt is provided with a cross groove for screwing in a screwdriver.

[0006] Furthermore, a buffer pad is provided on the side opposite to the threaded tube and the top bolt of the threaded hole.

[0007] Furthermore, mounting screws are provided at the four corners of the inner or outer side of the wiring mounting plate, and fastening bolts are provided on the mounting screws.

[0008] This utility model discloses a wiring device for a power distribution cabinet. Addressing the shortcomings of existing wiring requirements and the practical effectiveness of open-hole structures in power distribution boxes, it employs a slotted installation method in the cabinet wall for use with existing power distribution cabinets. While providing a through-type structure for both internal and external wiring, it can quickly and temporarily compress and stably tighten and fix the wires and wire ends as needed, avoiding safety hazards caused by wire slippage during operation and malfunctions caused by external pulling after wiring.

[0019] In this utility model, unless otherwise explicitly specified and limited, the terms "installation," "connection," "joining," and "fixing," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. For those skilled in the art, the specific meaning of the above terms in this utility model can be understood according to the specific circumstances.

[0020] In the description of this utility model, it should be understood that the terms "left", "right", "front", "rear", "top", "bottom", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0021] The present invention will be further described below with specific embodiments, but the scope of protection of the present invention is not limited to the following embodiments.

[0022] Implementation method 1: such as Figures 1 to 3 As shown, the wiring device of this distribution cabinet includes an insulating wire mounting plate 1. The wire mounting plate 1 is strip-shaped, with at least one row of wire holes 2 from top to bottom. Several threaded tubes 3 are threaded through each of the remaining wire holes 2 on one side, and a top wire bolt 4 is threaded into each threaded tube 3. An arc-shaped pressure plate 31 is provided at one end of each threaded tube 3 extending into the wire hole 2. During wiring operations, by pushing inward and pulling outward on the top wire bolt cap, the inserted or exiting wires and wire ends are quickly and temporarily clamped and fixed. The arc-shaped pressure plate on the threaded tube is pressed into and retracted into the wire hole, achieving quick and temporary clamping and fixing of the wires and wire ends. After the operation is completed, the wires are released. When stable clamping and fixing are required after the operation, the threaded tube is straightened, and finally, the cross-shaped screw on the top wire bolt cap is tightened, causing the top wire bolt to extend from the threaded tube and stably clamp and fix the wires.

[0023] Implementation Method 2: Wiring Device of this Distribution Cabinet: The bolt head of the top wire bolt 4 is provided with a cross-shaped groove 41 for screwing in a screwdriver. The wire hole 2 has a buffer rubber pad 21 on the opposite side of the wire thread tube 3 and the top wire bolt 4. This buffers the pressure on the wire and provides friction on the opposite side during pressure, thus securing the wire. The remaining structures and components are as described in Implementation Method 1 and will not be repeated.

[0024] Implementation method 3: such as Figure 4 As shown, the wiring mounting plate 1 of this distribution cabinet is provided with mounting screws 11 at the four corners of its inner or outer side, and fastening bolts are provided on the mounting screws 11. During installation, a long slot smaller than the wiring mounting plate is opened on the side wall of the distribution box, which can expose all the wiring holes. A mounting hole for inserting the mounting screw is opened on the outer side of the long slot. After the wiring mounting plate is installed in the long slot of the distribution box from the inside or outside of the distribution box by the cooperation of the mounting screw and the mounting hole, the installation is completed by fastening with the fastening bolt. The remaining structures and components are as described in Embodiment 1, and will not be described again.

[0025] This distribution cabinet wiring device addresses the shortcomings of existing distribution box wiring requirements and the practicality of open-hole structures in cabinet walls. It adopts a slotted installation method in the cabinet wall to be used in conjunction with existing distribution cabinets. While providing a through structure for wires to exit from inside the box and wires to enter from outside the box, it can quickly and temporarily clamp and fix the wires and wire ends as needed, and stabilize them with a top clamp. This avoids safety hazards caused by wires and wire ends slipping during operation and malfunctions caused by external pulling after wiring.
