Technical Field
The utility model relates to the technical field of cables, in particular to an aluminum conductor cable branch plurality of small-section copper conductor cables for trunk junction.
Background
The existing processing mode is to adopt a combiner box, plug the small-scale cable of the branch circuit into the combiner box by using a connector pair as an inlet end, draw out the end to a main circuit after combining, and allocate a plurality of combiner boxes in the whole electrical system, so that the cost is increased greatly, and professional personnel is required to construct during construction.
The existing process has two problems, the 1/copper conductor is connected with the aluminum conductor by adopting a copper-aluminum composite terminal connection mode, but the copper-aluminum composite terminal is connected by adopting a cold rolling process, the connection part is easy to generate overlarge resistance and metal of the copper-aluminum composite terminal and the aluminum composite terminal, after the connection part is subjected to cold-thermal shock, the creep degree is different, and the periodic performance can be greatly reduced along with the time; 2/the existing connection mode is influenced by the connection terminal, the quantity of the main aluminum conductor and the branch copper conductor is fixed, the type is single, the later processing cost is high, and the connection mode mainly depends on the shape of the copper-aluminum composite terminal.
Disclosure of Invention
The utility model aims to solve the defects that the existing connection mode is single, the manufacturing is difficult, the processing cost is high, the effective popularization cannot be achieved, the aluminum conductor cable for the large-section trunk junction and the aluminum conductor cable for the branch small-section copper conductor cables with different materials are connected in a transitional mode, and the potential safety hazards are caused by different creep performances.
In order to achieve the above purpose, the present utility model adopts the following technical scheme:
the utility model provides an aluminum conductor cable branch a plurality of small-section copper conductor cables for trunk line collection, includes disjunctor bearing structure, the pipe is installed in disjunctor bearing structure's outside, aluminum conductor cable is installed to disjunctor bearing structure's inboard, two wedge tightening element are all installed at the both ends of pipe.
Preferably, a plurality of contact ribs are arranged on the aluminum conductor cable.
Preferably, the aluminum conductor cable material is a copper-aluminum composite material.
Preferably, the aluminum conductor cable is provided with a fixing structure.
Preferably, the conjoined support structure and the fixing structure are arranged in a V shape.
The utility model can effectively solve the problem of safety performance of the aluminum conductor cable branch for large-section trunk junction and a plurality of small-section copper conductor cables, is not limited by conductor specifications, greatly reduces processing cost, is beneficial to cost reduction of the whole photovoltaic system in junction problem, and replaces the junction box.
