Problems solved by technology

[0007] However, the tubular metal foil member made of metal foil has a problem that breakage occurs more easily than the tubular knitted member if it is caulked under the same conditions as the tubular knitted member.
In addition, the tubular metal foil member has the problem of being more likely to break than the tubular knitted member when a tensile force is applied.
Therefore, there are problems such as a decrease in reliability and insufficient strength related to electrical connections.

Abstract

A swaging structure is provided, allowing to secure connection reliability or strength though a tubular metal foil member made of metal foil is included in its structure. The swaging, connection structure is the one that a ring-shaped swaging member is swaged so as to include an area of main contact with a plurality of points or plurality of lines and an area of main contact with area, and thereby to electrically and mechanically contact the tubular metal foil member and a tubular connection part. The swaging connection member is also made a connection structure arranged such that an edge of a circumferential edge part of the ring-shaped swaging member is arranged not to contact with the tubular metal foil member.

Description

technical field [0001] The present invention relates to a caulking connection structure in which a ring-shaped caulking member is caulked to electrically and mechanically connect a cylindrical metal foil member to a cylindrical connection portion. Background technique [0002] Patent Document 1 below discloses a technology related to a crimp connection structure in which an end portion of a cylindrical braided member arranged outside an electric wire and a cylindrical shield case are electrically connected by crimping an annular shield ring. In the above structure, the cylindrical braided member is formed into a cylindrical shape by braiding conductive ultra-thin wires. In addition, the shield shell is formed to have conductivity, and the end portion of the tubular braided member can be connected to the outer peripheral surface thereof. In addition, the shield ring is formed so that when crimping is performed with a caulking die with the cylindrical knitted member inserted ...
