Description

Technical Field

[0001] This utility model relates to the technical field of auxiliary devices for electrical equipment installation, and in particular to an auxiliary device for installing copper busbars of wiring terminals. Background Technology

[0002] When connecting the terminal block to the outside, it is fixed by a copper busbar. During installation, the copper busbar needs to be placed on the terminal block first, aligning the hole at one end of the copper busbar with the hole at the front end of the terminal block. Then, use a hex bolt to pass through the terminal block and the copper busbar from bottom to top, tighten the nut on top, and then connect the other end to the outside.

[0003] After the bolt passes through the terminal block and copper busbar from bottom to top, a wrench is used below to secure the outer wall of the hexagonal bolt, and another wrench is used above to tighten the terminal block and copper busbar. This process is prone to slippage or causing materials to fall. At the same time, when fixing one end of the copper busbar to the terminal block, it is necessary to keep the terminal block and copper busbar aligned and not form an angle between them. The overall fixing process is difficult, time-consuming and labor-intensive. Utility Model Content

[0004] The purpose of this invention is to provide an auxiliary device for installing copper busbars for wiring terminals.

[0005] The above-mentioned technical objective of this utility model is achieved through the following technical solution: a copper busbar installation auxiliary device for a terminal block, including a base, a U-shaped block on the base, and a retaining strip on both sides of the inner wall of the U-shaped block; both sides of the inner wall of the retaining strip abut against the outer wall of the hexagonal bolt; both sides of the inner wall of the U-shaped block abut against the outer walls of the terminal block and the outer walls of the copper busbar.

[0006] The U-shaped block is further configured such that its inner walls on both sides are provided with transverse one-way slots, and the card strip is inserted into the slots. The card strip includes multiple sizes.

[0007] Further configuration: The upper end of the U-shaped block is provided with plug-in blocks of different sizes.

[0008] The U-shaped block is further configured such that its bottom has extensions to both ends.

[0009] The further configuration is that the length of the card strip is greater than the length of the end of the U-shaped block.

[0010] In summary, this utility model has the following beneficial effects: The copper busbar installation auxiliary device for this terminal block not only secures the hexagonal bolts for easy tightening of the nuts, but also aligns the terminal block and the copper busbar, preventing an angle between them. This facilitates the connection and fixation of the terminal block and the copper busbar, achieving a synergistic effect, increasing work efficiency, and reducing the workload of workers.

[0014] The present invention will be further described in detail below with reference to the accompanying drawings.

[0015] Example 1: An auxiliary device for installing the copper busbar 9 of the terminal block 8 includes a base 1, which can be made of wood. A U-shaped block 2 is fixedly mounted on the base 1 by screws. The lower end of the U-shaped block 2 is preferably at a right angle to increase stability.

[0016] The inner walls of both sides of the U-shaped block 2 are welded with retaining strips 3, the length of which is greater than the length of the side ends of the U-shaped block 2. During installation, the inner walls of both sides of the retaining strips 3 abut against the outer walls of the hexagonal bolts 4, thus securing the hexagonal bolts 4 below. Simultaneously, the inner walls of both sides of the U-shaped block 2 abut against the outer walls of both sides of the terminal block 8, and also against the outer walls of both sides of the copper busbar 9. This structure ensures that the terminal block 8 and the copper busbar 9 are aligned without forming an angle between them, guaranteeing connection quality.

[0017] Preferably, the lower ends of the U-shaped block 2 are provided with extensions 7. The extensions 7 increase the stability of the U-shaped block 2 and increase its length, ensuring sufficient space for the wrench to tighten the bolt. The length of the retaining strip 3 is preferably equal to the length of the extensions 7.

[0018] Example 2: This example is largely the same as Example 1, except that one-way slots 5 are provided on the inner walls of both sides of the U-shaped block 2. The one-way slots 5 can be dovetail or slide rail structures to ensure the stability of the locking strip 3 when inserted into the one-way slot 5, and one inner end of the locking strip 3 abuts against the bottom of the slot 5. The width of the locking strip 3 can be of multiple sizes to accommodate hexagonal bolts 4 of different sizes.

[0019] Example 3: This example is largely the same as Example 1, except that plug-in blocks 6 are provided on both sides of the U-shaped block 2. The plug-in blocks 6 have different sizes depending on the size of the terminal block 8 and the copper busbar 9. The plug-in blocks 6 are inserted from top to bottom, and finally the inner walls of both sides of the plug-in blocks 6 are in contact with the outer walls of the terminal block 8 or the copper busbar 9.

[0020] Example 4: This example is largely the same as Example 1, except that the installation auxiliary device is set in three parallel groups to accommodate the three-way circuit structure on a conventional terminal block.

[0021] This specific embodiment is merely an explanation of the present utility model and is not intended to limit the present utility model. After reading this specification, those skilled in the art can make modifications to this embodiment without contributing any inventive step, but as long as they are within the scope of the claims of the present utility model, they are protected by patent law.
