Description

Technical Field

[0001] This utility model relates to the field of cable junction box technology, and specifically to a cable junction box structure. Background Technology

[0002] A cable junction box is a device used to split, branch, connect, and switch circuits in cable lines. Most of them are used outdoors. Cable junction boxes are divided into two main categories according to their electrical composition: one type does not contain any switching equipment, and the box only contains accessories for processing and connecting cable ends. It has a relatively simple structure and a single function, and can be called a standard junction box; the other type contains not only the accessories of a standard junction box, but also one or more switching devices. Its structure is more complex, its size is larger, and it has more connecting devices, and can be called a high-end junction box.

[0003] Existing cable junction boxes typically consist of a hinged upper and lower enclosure. During routine maintenance, the door flips up for operator access. However, the flipped door requires manual or tool support, and it is generally difficult to detach from the enclosure, increasing the risk of head injury during maintenance. Operators are often forced to squat while operating the box, and must retreat to the lower enclosure for rest, making it inconvenient to use. Utility Model Content
