Description

Technical Field

[0001] The utility model relates to the technical field of cable laying and connecting tools, in particular to a dry type cable T-junction box. Background Art

[0002] In the laying of transmission lines, the T-connection method is often used to connect cables. Cable T-connection refers to connecting the end of one cable to the middle of another cable to form a T shape. This connection method is mainly used for branching distribution lines or increasing the cable length of the line. After the wiring is completed, the connection is insulated with materials such as insulating tape, and testing and acceptance are carried out to ensure the quality and safety of the connection to prevent electric shock accidents.

[0003] After the traditional cable T-connection is completed, the metal conductor part of the cable and the end of the insulation layer are wrapped with insulating tape. Although the cable is wrapped with insulating tape, it lacks further fastening and sealing treatment. The tensile strength of the T-connection position is low and it is easy to break. If the cable is in a humid environment for a long time, the moisture in the air can easily penetrate the insulating tape and contact the metal wire inside the cable, causing corrosion of the metal wire.
