Description

Technical Field

[0001] The present invention specifically relates to a busbar made of aluminum and a processing method thereof. Background Art

[0002] A busbar made of aluminum is a conductive device used for distributing and transmitting current in a power system, usually made of aluminum material. Its main function is to distribute electric power from one point to multiple electrical devices or circuits. Busbars made of aluminum are usually used in power facilities such as distribution boxes, substations, switchgear cabinets, etc., as an important power transmission component.

[0003] In the process of using the existing busbars made of aluminum, the length of the busbars is usually fixed. When a longer busbar is needed, a longer one needs to be purchased additionally for installation, increasing the installation and use costs. Moreover, the shorter busbars are also idle and wasted, and the use effect is not good. In addition, the multi-layer busbars made of aluminum have fixed upper and lower multi-layer insertion parts. However, during use, it is not convenient to adjust the distance between the upper and lower insertion parts. For this reason, we propose a busbar made of aluminum and a processing method thereof. Summary of the Invention

[0004] The purpose of the present invention is to provide a busbar made of aluminum and a processing method thereof to solve the problems raised in the above background art.

[0011] Preferably, the elastic conductive component includes a conductive plate, a connecting cable, and a spring. The conductive plate is slidably arranged inside the first plugging block, and the conductive plate is in contact with the conductive aluminum bar.

A frame plate protruding outward is formed on one side wall of the second baffle and inserted into the inside of the first plugging block, and clamping plates cooperating with the first plugging block are arranged on both end faces of the frame plate.

[0014] Preferably, mounting bolts for connecting with the insulating housing are arranged on the inner edge of the second baffle.

[0016] Preferably, the conductive structure includes elastic clamping blocks and conductive sheets. The conductive sheets are fixed inside the groove, and elastic clamping blocks cooperating with the conductive columns are arranged on the edges of the conductive sheets.

[0017] Preferably, three elastic clamping blocks are evenly distributed along the circumferential direction of the conductive sheet.

[0018] A processing method of a bus aluminum row includes the following steps:

[0019] Step A: Cut the aluminum material into aluminum plates, then bend the side walls of the aluminum plates to form insertion parts, and after processing, form an integral conductive aluminum row, and then form an insulating housing by injection molding.

[0020] Step B: Injection-mold the first plugging block, then arrange the connecting cable on one side wall of the first plugging block, and sleeved with a spring outside the connecting cable, and a conductive plate is fixed at one end of the connecting cable.

[0021] Step C: Form conductive conductive sheets and elastic clamping blocks by stamping. One end face of the conductive sheet is electrically connected to the connecting cable, and then slide the conductive aluminum row into the inside of the insulating housing so that the aluminum plate is in contact with the conductive plate.

[0022] Step D: Fix the second baffle to one end of the insulating housing through the mounting bolts to prevent the conductive aluminum row from accidentally sliding out from the inside of the insulating housing, and then the assembly of the entire aluminum row can be completed. Then, according to the actual length used, insert the frame plate into the inside of the groove so that the conductive column is in contact with the conductive sheet to realize the electrical connection of two aluminum rows.

[0023] Step E: When connecting to an external circuit, the conductive aluminum row can be pushed left and right to adjust the distance between the insertion parts of the two layers of conductive aluminum rows.

[0024] Compared with the prior art, the beneficial effects of the present invention are:
