An Ultra-thin Copper Foil Longitudinal Wrapping Die for Ultra-thin Coaxial Wires

Abstract

The invention provides a longitudinal lapping mould for a fine coaxial-line ultra-thin copper coil, which comprises a fixed die and a forming die, wherein the fixed die is cylindrical; a feed zone and a forming section are sequentially arranged on the fixed die in the axial direction; a feed opening is formed in the feed zone in the axial line direction; a wire core slot and a copper foil slot penetrate and are formed in the forming section in the axial line direction; the feeding opening is communicated with the wire core slot and the copper coil slot; the forming die is arranged at the front of the axial line direction of the fixed die; a forming hole in the axial line direction penetrates through the forming die; a horn-shaped opening with the aperture growing from small to big from inside to outside is formed in one end, facing the fixed die, of the forming hole. Compared with the prior art, the mould provided by the invention has the advantages that the defects of flanging, edge warping, uniformly wrapping and the like of the cooper coil in the production are overcome, the outer diameters of produced fine copper coil wires are uniform, die blocking and wire breaking caused by fluctuation of the outer diameters are avoided, the quality of products is better, the yield is higher, and the production cost is greatly reduced.

Description

technical field [0001] The invention relates to a longitudinal wrapping die for processing coaxial lines, in particular to a longitudinal wrapping die for ultra-thin coaxial lines and ultra-thin copper foils. Background technique [0002] At present, the technology widely used in the field of ultra-thin coaxial cable longitudinal wrapping is to imitate the gradual molding method of the more common tapered longitudinal wrapping mold in cables. Because the ultra-thin coaxial cables used in notebook computers, liquid crystal displays, medical equipment and mobile communication equipment are relatively thin, the copper foil used is very thin, and the copper foil is easily broken and easily stretched and deformed after being subjected to force. The technical longitudinal wrapping mold mechanism has the following defects in the production process: on the one hand, after the copper foil is longitudinally wrapped, there are often phenomena such as flanging, warping, and uneven cover...

Problems solved by technology

Because the ultra-thin coaxial cables used in notebook computers, liquid crystal displays, medical equipment and mobile communication equipment are relatively thin, the copper foil used is very thin, and the copper foil is easily broken and easily stretched and deformed after being subjected to force. The technical longitudinal wrapping mold mechanism has the following defects in the production process: on the one hand, after the copper foil is longitudinally wrapped, there are often phenomena such as flanging, warping, and uneven covering; on the other hand, the fluctuation of the outer diameter of the wire causes the mold to Mouth plugging and disconnection seriously affect the quality of the entire wire longitudinal package, thus destroying the electrical performance and integrity of the wire

Since the ultra-fine coaxial cable cannot be repaired and reused after an abnormality occurs in the production, the production cost of the ultra-fine coaxial cable is greatly increased due to the above-mentioned defects in the longitudinal package mold of the prior art
