Fflexible conductor and manufacturing method of flexible conductor

Abstract

The invention provides a flexible conductor and manufacturing method of flexible conductor, capable of preventing sheet tilting of stacking body and capable of preventing the phenomenon that the sheet is cut off when the stacking body movement is prevented, so that it has long-term use. The soft conductor has a stacking body formed by stacking several sheets and having electroconductivity and flexibility, terminal parts provided at both ends of the stacking body, protective plates provided at the joint parts of the terminal parts and the stacking body and preventing the sheet tilting. The stacking body is jointed to the terminal parts through mixing and frictionally-engaging, and curved surface parts are formed at the ends of the protective plates facing to one side of the sheet.

Description

technical field [0001] The present invention relates to a flexible conductor and a method for manufacturing the flexible conductor, and in particular to a flexible conductor obtained by joining a laminate having electrical conductivity and flexibility formed by laminating a plurality of thin plates, and terminals provided at both ends of the laminate. Conductor and flexible conductor manufacturing method. Background technique [0002] Soft conductors are also called copper strips, laminated copper foils (コペル), etc., such as Figure 10 As shown, the flexible conductor 300 is obtained by joining a laminated body 301 to terminal portions 302 and 303 provided at both ends of the laminated body 301 . The laminated body 301 is formed by laminating a plurality of thin plates, and has conductivity and flexibility. The terminal portions 302 and 303 are respectively joined to one end portion and the other end portion of the laminated body 301 . [0003] One terminal portion 302 of s...

Problems solved by technology

A lot of work is required to remove this discoloration

[0011] In addition, the electrical performance of the welded part is worse than that of ordinary pure copper and pure aluminum

In the case of soft conductors fixed by electron beam welding, the heating is done instantaneously, and the softened part does not burn at all, but there is a problem with productivity due to batch processing due to equipment

[0012] In addition, when the friction stir welding technique described in Patent Document 1 is used for the production of flexible conductors, when friction stir welding is performed on the joint between the laminate and the terminal portion, the thin plate of the laminate may warp due to the action of the friction stir, and it cannot be welded. Make a sound joint

In addition, when the flexible conductor is actually used and the laminate is movable, the thin plate of the laminate may be cut near the terminal portion, so it cannot be used for a long period of time.
