Abstract
The utility model discloses a low-voltage cable distributing box, comprising a box, a box cover connected with the box, a junction box arranged in the box, an air switch or fuse and a zero line row, which is characterized in that: a conductive bus-bar is arranged in the box; the junction box is provided with a cable clamping device connected with the conductive bus-bar; the air switch is connected with an adaptor; the adaptor is connected with the conductive bus-bar. The low-voltage cable distributing box can be an intermediate box or a terminal box. The cable distributing box adopts the cable clamping device in the junction box to be connected with the conductive bus-bar, and the conductive parts of cables are all directly inserted in the junction box, thereby, ''nose pressing'' is not needed in installation and construction, which is convenient, simple and safe; the adaptor is adopted to change the wiring direction of the air switch, i.e. the in-out parallel connecting direction is changed into perpendicular connecting direction, which shortens wiring length and correspondingly shortens the length of the distributing box. The cables of various models can be installed and fixed on the cable distributing box, and the orderly arrangement is convenient for the installation and maintenance of a whole building and apartment house.
Description
Technical field
The utility model belongs to the low-voltage cable coupling box, is specifically related in the middle of the low-voltage cable or the terminal coupling box.
Background technology
Present widely used cable hut comprises termination rack and intermediate box, during construction and installation, cable need be connected with joint pin earlier, being commonly called as " pressure nose " is connected joint pin then with terminal box, the 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 purpose of this utility model is to provide a kind of low-voltage cable coupling box with the closed connection of adapter, to overcome the defective of above-mentioned cable hut.
The technical solution of the utility model is such: the low-voltage cable coupling box, it 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, establish the atresia conductive bus bar in the casing, the terminal box back side and conductive bus bar conduction is connected, and specifically annexation is that terminal box is established cable clamping device and is connected with conductive bus bar, described air switch connects adapter, and the adapter back side is connected with the conductive bus bar conduction.
This technical scheme is an intermediate box as adopting terminal box and air switch, and adopting terminal box and fuse is termination rack.The cable clamping device in this cable hut employing terminal box and the conductive bus bar employing hidden back of the body connect formula and are connected, the current-carrying part of cable is all directly in terminal box, change the mode of connection of traditional busbar, crimping line nose, installing, need not when constructing " pressure nose " direct insertion gets final product, convenient and simple, safety; Adopt adapter to change the wiring direction of air switch, make the parallel closure of turnover into vertical closure, shortened wiring length, the corresponding length that shortens coupling box.The cable of all kinds of models all can install on cable hut, fixing, marshalling is convenient to the installation and the maintenance of bed rearrangement building, door.
