Technical Field

[0001] This utility model relates to the field of construction, and in particular to a junction box for building electrical installation. Background Technology

[0002] In the field of building electrical installation, junction boxes are commonly used electrical components for connecting, branching, and securing cables. With the increasing complexity of building electrical systems, higher requirements are being placed on cable connections and management.

[0003] Traditional junction boxes have a relatively simple structure, typically consisting of a fixed-shape and-size housing with internal wire-clamping mechanisms. This design has several limitations: Firstly, because the wire-clamping structure is fixed, the number of wire-clamping slots cannot be flexibly adjusted according to the actual number of wires required. This means that in practical applications, when the number of wires changes, different specifications of junction boxes may need to be replaced, increasing costs and construction difficulty. Secondly, traditional junction boxes struggle to provide adequate fixing space for cables of different diameters. Cables may be too loosely secured, leading to slippage, or too tightly secured, potentially damaging the cables and affecting the quality and safety of electrical connections. Furthermore, the lack of effective guidance and stabilizing devices when adjusting the wire-clamping structure makes the adjustment process less smooth and accurate, further impacting the junction box's performance. Additionally, the cable entry hole design of traditional junction boxes fails to effectively prevent cable slippage, causing inconvenience during construction and maintenance. Therefore, a new type of building electrical installation junction box that can solve these problems is needed. Utility Model Content

[0004] The purpose of this utility model is to provide a building electrical installation junction box. Through flexible adjustment (number + diameter), stable fixing, safety protection, and convenient operation, it solves the problems of poor adaptability, unstable fixing, and troublesome maintenance of traditional building electrical junction boxes.
