Abstract
The utility model discloses a low-voltage cable branch box which comprises a box body, a box cover connected with the box body, a junction box arranged in the box body, an air switch or fuse, a zero line bar and a conductive bus-bar arranged in the box body. Wherein the junction box is provided with a cable clamping device which is connected with the conductive bus-bar; a connection terminal at one end of the air switch is connected with a conductive bar which is connected with the conductive bus-bar. The structure adopted in the cable branch box that the cable clamping device in the junction box is connected with the conductive bus-bar, the conductive parts of the cable wire are both directly arranged in the junction box, therefore the installation and construction can be realized by directly inter-insertion without <nose press>; the connection terminal at one end of the air switch is connection with the conductive bus-bar, convenient simple and safe in connection. Thus various cables can be installed and fixed on the cable branch box.
Description
Technical field
The utility model belongs to the low-voltage cable coupling box, is specifically related to the middle distribution box of low-voltage cable.
Background technology
The intermediate box of present widely used cable hut during construction and installation, need be connected cable earlier with joint pin, be commonly called as " pressure nose " and then joint pin be connected with terminal box, installation complexity, inconvenient time-consuming taking a lot of work, bronze medal is exposed outside, easily causes the electrical safety accident.For intermediate box, because the turnover line of air switch connects by two ends up and down, size for connection is bigger, causes the size of cable hut bigger, increases the material cost of casing.
Summary of the invention
The low-voltage cable distribution box that the purpose of this utility model is to provide a kind of terminals of air switch one end directly to connect conductive bus bar is to overcome above-mentioned deficiency.
The technical solution of the utility model is: the low-voltage cable distribution box comprises casing, the case lid that is connected with casing, the terminal box of establishing in the casing, air switch or fuse, zero line row establishes conductive bus bar in the casing, terminal box is established cable clamping device and is connected with conductive bus bar, the terminals of described air switch one end connect busbar, and busbar is connected with conductive bus bar.
This cable hut adopts the cable clamping device in the terminal box to be connected with conductive bus bar, the current-carrying part of cable all directly in terminal box, is installed, need not to insert between " pressure nose " during construction and get final product, and is connected with conductive bus bar between the terminals of air switch one end, convenient and simple, safety; The cable of all kinds of models all can be installed on cable hut, fix.
