Description

Lamp junction box

Technical Field

Background

Some lamps, such as ultra-thin downlights, are fixed by first installing a junction box at the installation position of the lamp and then fixing the lamp on the junction box. Screws are often used as fixing parts in the fixed installation of the junction box and the lamp.

The junction box for mounting a lamp is different from a general junction box for mounting a pipeline in that a box portion of the junction box for mounting a pipeline is often buried in a firm wall, and the junction box for mounting a lamp is often mounted on a ceiling.

The junction box buried in the wall often has no problems of firmness in fixation and deviation from the top when other objects are installed at the later stage; when the junction box is installed on the ceiling, the problems of poor fixation and easy top deflection may occur. Particularly, when the ceiling is made of a material with a soft texture, such as wood, the junction box needs to be installed on the ceiling first, and then the lamp is fixed on the junction box, the junction box fixed on the ceiling is prone to being pushed up and down in the process of screwing screws for fixing the lamp, and the screws for fixing the lamp are prone to shaking up and down when the screws are screwed down, so that the screws for fixing and connecting the ceiling and the junction box are loosened, and even the hidden trouble of falling is caused.

When an object is mounted on a hard material by screws, it is necessary to prefabricate screw holes on the material, which inevitably leads to an increase in manufacturing cost. Cost considerations in the finishing industry often do not simply replace the ceiling material with a more rigid material. Compared with harder and heavier materials, the soft materials can be used, the screws can be easily drilled in, and the materials are lighter and more suitable for application in decoration and finishing engineering. Therefore, when the junction box for installing the lamp is fixed on the ceiling with soft texture, the junction box capable of overcoming the defects that the junction box is easy to be inclined to the top and even screws are loosened when the lamp is installed is needed.
