[0002] The cable junction box is the most common and widely used connection device in the fields of construction and communications, which can protect the connector components. In addition to the general functional requirements of the existing finished junction boxes, different types of new cable junction boxes have gradually been developed. For example, there are waterproof and splash-proof junction boxes, thermocouple junction boxes, explosion-proof junction boxes, solar junction boxes and other styles of cable junction boxes to meet the needs of different functional junction boxes under different working conditions. However, the general cable junction box adopts an ordinary connection method, so its signal shielding effect is not good, which affects normal communication. At the same time, the connection at the joint is not tight, which is easy to cause slippage; in addition, the existing junction box is inconvenient to install, difficult to install flexibly according to the thickness of the wall, and the heat dissipation effect is not good.

[0003] In order to solve the deficiencies of the prior art, people have conducted long-term exploration and proposed various solutions.
