Description

Technical Field

[0001] The utility model relates to the technical field of circuit connection auxiliary equipment, in particular to a guide rail type single-pole busbar junction box. Background Art

[0002] The guide rail type junction box is usually installed on a metal guide rail. A plurality of junction boxes are usually installed on a metal guide rail at the same time. For example, Chinese patent publication number CN202978148U discloses a junction wire box, including a box body and a box cover that cooperate with each other. The bottom of the box body has a slide groove that matches the guide rail, and the top two side edges of the box body have a plurality of bayonet holes arranged in pairs. The bottom two side edges of the box cover have a plurality of hooks that are engaged with the bayonet holes, and the hooks correspond to the bayonet holes one by one. During use, the assembly between the box body and the box cover can be completed by only snapping the corresponding hooks and bayonet holes together. The entire assembly process is simple and easy, and no additional connectors are required, which greatly reduces the overall production cost of the junction wire box.

[0003] However, the guide rail type junction box in this solution lacks a fixed structure, which leads to collision or shaking between the junction boxes when multiple junction boxes are installed on the metal guide rail, resulting in low installation stability. There is also no structure to limit the terminal block in the junction box, which leads to vibration and shaking of the terminal block in the junction box, which in turn causes the wires to loosen or even fall off, affecting normal use.
