Description

Technical Field

[0001] The invention relates to the technical field of terminal fixing, in particular to a terminal fixing device for an electrical cabinet. Background Art

[0002] Electrical cabinet terminals are components used to connect electrical cables or wires. They are usually used to connect different circuits or external devices. Terminals usually include a conductive part and a fixed part. The conductive part is used to connect the wires, and the fixed part is used to fix the wires to ensure a firm and reliable connection.

[0003] For example, the "electrical cabinet terminal fixing device" with publication number CN104393498B includes a bent steel plate continuously bent into a serrated shape, and reinforcing plates welded to the upper and lower sides of the bent steel plate. The two sides of the serrated surface of the bent steel plate are respectively a mounting surface and a threading surface, and the multiple threading surfaces are parallel to each other, and the multiple mounting surfaces are parallel to each other; the threading surface and the mounting surface intersect at 90°, and a guide rail for clamping the terminal is provided on the mounting surface, and a strip threading hole is provided on the threading surface.

[0012] Preferably, a T-shaped plate is fixedly connected to one side of the movable plate, the T-shaped plate is slidably connected to the positioning shell, a strip hole is opened at the intersection of the positioning shell and the T-shaped plate, and an anti-slip convex strip is fixedly installed on the inner wall of the positioning shell.

[0016] Compared with the prior art, the present invention has the following beneficial effects: 1. In the present invention, by realizing the height of the lifting and locking assembly inside the lifting assembly, the internal space of the electrical cabinet can be effectively saved and the utilization efficiency can be improved. Under normal circumstances, the lifting assembly and the locking assembly are both arranged inside the positioning shell and will not take up too much space. Only when it is needed, the operator needs to pull out the lifting assembly and lift the locking assembly to a height close to the closed cover plate to facilitate the insertion of the wiring terminal. This design saves space and facilitates the operator to connect the wires. In addition, since the entire locking assembly is not directly connected to the electrical cabinet, the vibration of the electrical cabinet will not have too much impact on the stability of the wiring terminal. This ensures that the wiring terminal can maintain normal use in a high-frequency and high-amplitude vibration environment without loosening or falling off, thereby improving the stability and reliability of the equipment. In addition, the design of the adjustable angle of the lifting assembly prevents the wiring terminal from contacting the cabinet door, further reducing the impact of the cabinet vibration on the wiring terminal.

[0017] 2. In the present invention, the upper and lower distribution of the first support plate and the second support plate, and the symmetrical distribution of the first clamping plate and the second clamping plate with the two support plates, constitute a more stable and balanced support structure. When fixing the wiring terminals, the three-dimensional fixing method can fix the wiring terminals from four directions. Compared with the traditional single bolt fixing method, its stability is better. In addition, since the first clamping plate and the second clamping plate symmetrically distribute the positions of the wiring terminals, the position of the wiring terminals can be automatically calibrated during the fixing process. This design can effectively avoid the problem of misalignment of the wiring terminals and ensure that each wiring terminal is in the same straight line, thereby improving the overall connection quality and stability. Through such a three-dimensional fixing method and position calibration design, the safety and accuracy of the wiring terminals in the fixing process are enhanced, making the connecting components more reliable and durable during operation.

[0018] 3. In the present invention, through the sliding connection between the T-shaped plate and the positioning shell, the movable plate can move accurately and cooperate with the anti-slip convex strips on the inner wall of the positioning shell to achieve the limitation of the movable plate. In this way, it can ensure that the movable plate remains stable during operation, and it also helps to determine the moving route of the movable plate to prevent it from tilting or deviating from the predetermined position. In addition, the limit plate on the inner wall of the positioning shell controls the state of the first lifting rod through the bending groove. When the docking rod moves to the bending part of the bending groove, the angle of the limit plate will change, thereby affecting the position of the lifting load-bearing plate, thereby realizing the control and adjustment of the lifting plate. This design can ensure the stability and accuracy of the lifting assembly, and can reliably realize the lifting operation in various working environments, effectively ensuring the normal operation and safety of the equipment.

[0025] In this embodiment, the positioning block 39 is used to determine the position of the threaded rod 310. The threaded rod 310 is rotatably connected to the first clamping plate 33. When the first clamping plate 33 needs to be pushed, the threaded rod 310 can be rotated to achieve the purpose of pushing the first clamping plate 33 to move. The threaded connection method can ensure the stability of the first clamping plate 33, and can also accurately control the moving distance of the first clamping plate 33 to prevent a gap from being left between the first clamping plate 33 and the terminal. A guide plate 313 is provided on the upper surface of the first support plate 31 and the second support plate 32, and a guide slot 314 is provided at the bottom of the first support plate 31 and the second support plate 32 to connect with the guide plate 313, so that the guide plate 313 can determine the moving route of the first clamping plate 33 and the second clamping plate 34, and prevent the first clamping plate 33 and the second clamping plate 34 from falling off the support plate; The lower surfaces of the first clamping plate 33 and the second clamping plate 34 are both provided with accommodating grooves 315 , wherein the guide groove 314 under the first clamping plate 33 is used to accommodate the second tooth plate 37 , and the guide groove 314 at the bottom of the second clamping plate 34 is used to accommodate the first tooth plate 36 .
