technical field

The utility model relates to the technical field of weak current equipment, in particular to a weak current box.

Background technique

In 2002, the country started to implement the policy of separating strong and weak electricity, and the weak electricity box came into being. The weak current signal is disturbed by the strong current, which improves the quality of life of the family.

The patent document with the existing authorization announcement number CN204230820U discloses a weak current wiring box, which includes a box body and a protective door. The four corners of the box body are provided with mounting seats, and the interior of the box body is provided with three partitions from top to bottom. A clapboard and the upper end of the box form a cable TV distributor installation area, a telephone splitter installation area is formed between the second clapboard and the first clapboard, and a third clapboard and the second clapboard are installed. A network signal switch installation area is formed, a user expansion area is formed between the third partition and the lower end of the box, and both sides of the cable TV distributor installation area, the telephone splitter installation area, the network signal switch installation area and the user expansion area are There are inlet and outlet holes.

The above-mentioned weak current wiring box divides the interior of the weak current wiring box into different areas through partitions, so that each area is independent, so that the lines in each area will not be mixed, and can be discharged in order, reducing the probability of accidents.

However, when the weak current wiring box needs to be repaired, the protection door of the corresponding area needs to be opened for maintenance. Since each partition is not detachable and connected to the box body, the space in the corresponding area is limited. When maintenance is required, it is located near the rear wall of the box body. When the weak current equipment is installed at the same place, since the partition plate and the box are not detachable, the weak current equipment on the side close to the protection door interferes with the weak current equipment on the side close to the rear wall of the box, which is not conducive to the maintenance and removal of the weak current equipment. .

Utility model content

Aiming at the deficiencies of the prior art, the purpose of the present invention is to provide a weak current box, which has the advantages of being able to move the partition plate out of the box body, facilitating maintenance and taking the weak current equipment.

The above-mentioned technical purpose of the present utility model is achieved through the following technical solutions:
