Problems solved by technology
Affected by the process, the aluminum tube cannot be too long, at least not the ideal length, otherwise it will cause inconvenience to the subsequent copper cladding process. As the inner conductor tube of cable communication, its length must be quite long, so the tube must be connected Growing tubes, and poor connections between tubes will affect the quality of signal transmission

Embodiment Construction
[0010] See figure 1 , figure 2 , the present invention includes a copper-clad aluminum pipe section 5, the two ends of the pipe section 5 are respectively processed with left-handed and right-handed internal threads, and the copper-clad aluminum pipe sections 5 are connected by double-headed left-handed and right-handed two-way threaded pipe joints 3 to form a long pipe. During the installation, as long as the rotating joint 3 is needed, the aluminum tubes on both sides can be connected as a whole, and then at the interface 4, the copper tubes 2 of the adjacent tube sections and the aluminum tubes 1 are respectively welded and connected, and then the copper tubes 2 are welded. Copper plated surface.

The invention relates to a pipe connection structure of a conductor pipe in an RF cable. The tube can be processed to a needed length by the connection structure and the signal transmission quality is good. The pipe connection structure of a conductor pipe in a RF cable comprises copper cladding aluminum pipe sections. The pipe connection structure of a conductor pipe in a RF cable is characterized in that the two ends of the pipe section are respectively processed with a levorotatory inner thread and a dextrogyrate inner thread; the copper cladding aluminum pipe sections are connected by a double-head levorotatory bidirectional screwed conduit joint and a double-head dextrogyrate bidirectional screwed conduit joint to form a long pipe; the copper pipes of neighboring pipe sections are welded and connected at the locations of the joints.
Description
(1) Technical field [0001] The invention relates to the technical field of communication cables, wireless communication and monitoring network digital signal transmission conductor tubes, in particular to a tube connection structure for conductor tubes in radio frequency cables. (2) Background technology [0002] At present, all pure copper inner conductor tubes are used in the cable industry. Copper is a globally scarce resource. Since copper is larger than aluminum and the price is high, cables processed with pure copper inner conductors are heavy in weight and high in cost, resulting in high costs for wireless communication and network engineering. Now the national annual usage has reached millions of tons, resulting in a huge consumption of copper resources. Now the industry has developed a new conductor tube - copper-clad aluminum tube, which objectively has the advantages of light weight and low cost, and is convenient for network engineering construction. However, s...
