A production process for slotting outer conductor of leaky cable

Abstract

The invention provides a production process for slotting the outer conductor of a leaky cable, which combines the metal strip slotting and the metal strip longitudinal wrapping and sheathing process production line into an integrated production line, thereby saving the operation and storage of raw materials, and avoiding the Waste or pollution in the process; and efficient and reliable production. After the production of semi-finished products output from the leaky cable insulation process is completed, use CNC laser cutting equipment to laser cut corresponding slots on the metal strip according to specific slotting parameters to produce slotted outer conductors, and then roll the slotted metal strips After the pattern, the outer conductor is directly coated on the insulation by the outer conductor longitudinal wrapping mold, and finally the sheath production is directly completed by the sheath extruder, and the finished leaky cable is produced, so that the outer conductor of the leaky cable is punched from the raw material to the raw material, longitudinally wrapped The three processes of forming and outer sheath after forming the outer conductor are completed at one time.

Description

technical field [0001] The invention relates to the technical field of making leaky cables, in particular to a production process for slotting outer conductors of leaky cables. Background technique [0002] Leaky coaxial cable is a special type of radio frequency coaxial cable. The special feature is that a series of slots need to be made on the outer conductor that acts as a shield, so that the electromagnetic energy transmitted inside the leaky cable can pass through the slots. The hole leaks radiation outward, and the electromagnetic energy in the external environment of the leaky cable can be coupled and absorbed inward through the slot hole to complete the signal interaction between the leaky cable and the external environment, and to meet the requirement of mobile communication along the line (along the laying direction of the leaky cable). signal request. [0003] Leaky coaxial cables can be divided into coupling type leaky cables and radiation type leaky cables acco...

Problems solved by technology

[0004] 1 Raw materials are operated in different processes in each workshop, and storage takes up too much time and space, and is easily affected by environmental pollution and affects the quality of use. At the same time, the separate thin copper strip punching process in the outer conductor process needs to reserve operating areas and equipment Area, occupying a large space;

[0005] 2. In the outer conductor process, the separate process of punching thin copper strips needs to match the product quantity with the finished product process, resulting in a larger production quantity of the outer conductor than the latter process. Excessive production leads to more waste of materials in the final process;

[0006] 3 The slotted thin copper strip used for the outer conductor produced by the punching machine, due to the problem of equipment technology, the precision fluctuates greatly;

[0007] 4. Using a punching machine to produce slotted thin copper strips for outer conductors requires the use of stamping dies, and each die can only be used for one slotting structure. The cost of the die is high. When changing the slotting structure, the die needs to be replaced, which cannot be flexibly produced and cannot meet the requirements. Create multiple groups of slotted structures in a continuous leaky cable;

[0008] 5 To use a punching machine to produce slotted thin copper strips for outer conductors, it is necessary to pre-open molds for different groove types, and in order to ensure the stamping quality and service life of the molds, the mold processing is complicated and the mold opening takes a long time
