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.

Claims

1. A swaging connection structure, comprising:

a tubular metal foil member made by forming conductive metal foil into tubular shape;

a tubular connection part made of conductive metal and configured to be inserted inside the tubular metal foil member; and

a metallic ring-shaped swaging member deformable by swaging, and configured to pass the tubular metal foil member therethrough, the ring-shaped swaging member including a first deformed part, and a second deformed part, both formed inwardly into edgeless shape by swaging the ring-shaped swaging member from its outside to inside,

wherein the tubular metal foil member and the tubular connection part are made to abut to each other by the first deformed part and by the second deformed part so as to be mechanically and electrically connected with each other.

2. The swaging connection structure as claimed in claim 1, wherein the first deformed part of the ring-shaped swaging member is configured by an edgeless deformed part contacting at area the tubular metal foil member and the tubular connection part, and wherein the second deformed part of the ring-shaped swaging member is a plurality of edgeless deformed parts contacting the tubular metal foil member and the tubular connection part in one way selected from at point, at line, and at area narrower than the first deformed part.

3. The swaging connection structure as claimed in claim 2, wherein the second deformed part is configured by a plurality of edgeless deformed parts of lines arranged parallel to an axis of the ring-shaped swaging member, and in a radial direction of the ring-shaped swaging member.

4. The swaging connection structure as claimed in claim 2, wherein the second deformed part is configured by a plurality of edgeless deformed parts arranged at intervals in a radial direction of the ring-shaped swaging member.

5. The swaging connection structure as claimed in claim 1, wherein the first deformed part is located where more tension is placed in the tubular metal foil member than the second deformed part.

6. The swaging connection structure as claimed in claim 1, wherein the tubular metal foil member is made of a metal foil or multi-layer including the metal foil.

7. The swaging connection structure as claimed in claim 2, wherein the first deformed part is located where more tension is placed in the tubular metal foil member than the second deformed part.

8. The swaging connection structure as claimed in claim 3, wherein the first deformed part is located where more tension is placed in the tubular metal foil member than the second deformed part.

9. The swaging connection structure as claimed in claim 4, wherein the first deformed part is located where more tension is placed in the tubular metal foil member than the second deformed part.

10. The swaging connection structure as claimed in claim 2, wherein the tubular metal foil member is made of a metal foil or multi-layer including the metal foil.

11. The swaging connection structure as claimed in claim 3, wherein the tubular metal foil member is made of a metal foil or multi-layer including the metal foil.

12. The swaging connection structure as claimed in claim 4, wherein the tubular metal foil member is made of a metal foil or multi-layer including the metal foil.

13. The swaging connection structure as claimed in claim 5, wherein the tubular metal foil member is made of a metal foil or multi-layer including the metal foil.

14. The swaging connection structure as claimed in claim 7, wherein the tubular metal foil member is made of a metal foil or multi-layer including the metal foil.

15. The swaging connection structure as claimed in claim 8, wherein the tubular metal foil member is made of a metal foil or multi-layer including the metal foil.

16. The swaging connection structure as claimed in claim 9, wherein the tubular metal foil member is made of a metal foil or multi-layer including the metal foil.
