Description

Technical Field

[0001] The utility model belongs to the technical field of cable branch boxes, in particular to a cable branch box with good stability. Background Art

[0002] The function of the cable branch box is to branch or transfer cables. With the development of the cableization of distribution networks, when independent loads with small capacity are distributed more concentratedly, branch boxes can be used for branch connections. When in use, one end of the multiple cables in the branch box is connected to the tap, and the other end passes through the branch box shell and extends to the outside. The existing branch box has a poor effect on fixing and limiting the cables inside. When the cables on the outside are pulled and moved, it is very easy to cause the connection between the cables and the tap to loosen or even break, affecting the stability of the cable connection. Utility Model Content
