Abstract

A connecting structure in which the electric cable having an insulated coating and the electrically conductive member with non-insulated coating are connected through a connecting terminal having a junction support member by applying an electric current, heating and applying a pressure; and the electric cables having an insulated coating and are connected mutually to one another through a connecting terminal having an electrically conductive member with non-insulated coating and a junction support member by applying an electric current, heating and applying a pressure, and a connecting method in which those connections are established by applying an electric current, applying a heat and applying a pressure, and a rotating electric machinery having that connecting structure and an alternating current generator using this machinery.

Claims

1. A connecting method, comprising the steps:

arranging side and side an electric cable having an insulated coating and an uninsulated electrically conductive member with a connecting terminal through a junction support member; and

connecting to each other said electric cable and said uninsulated electrically conductive member in a direction in which said electric cable and said uninsulated electrically conductive member with are not overlapped by applying an electric current, applying heat and applying pressure whereby when said electric current flows through said uninsulated electrically conductive member said heat is generated by said junction support member and said uninsulated electrically conductive member to soften and remove said insulating coating from said electric cable.

2. A connecting method according to claim 1, wherein

said connecting terminal is a U-shaped connecting terminal or a ring shaped connecting terminal, said method including;

a connecting target member corresponding to individual connections for said electric cable having said insulated coating, wherein said uninsulated electrically conductive member is integrated in said connecting terminal; and

connecting said connecting target member by applying an electric current, applying heat and applying pressure from both sides of a flat plate face of said connecting terminal.

3. A connecting method according to claim 1, wherein

said connecting terminal is a U-shaped connecting terminal, said method including;

a connecting target member corresponding to individual connections for said electric cable having said insulated coating, wherein said uninsulated electrically conductive member, and said electric cable having said insulated coating are integrated in said connecting terminal;

arranging said uninsulated electrically conductive member or said electric cable having said insulated coating inside an open side of said U-shaped connecting terminal; and

connecting said uninsulated electrically conductive member or said electric cable having said insulated coating by applying an electric current, apply heat and applying pressure connected from both sides of a flat pate face of said U-shaped connecting terminal.

4. A connecting method comprising the steps:

arranging side by side an electric cable having an insulated coating and an uninsulated electric cable with a connecting terminal through a junction support member; and

connecting to each other said electric cable having said insulated coating and said uninsulated electric cable in a direction in which said electric cable having said insulated coating and said uninsulated electric cable are not overlapped by applying an electric current, applying heat and applying pressure whereby heat generated by said junction support member and said uninsulated electric cable in response said electric current through said electric cable having said insulating coating removes said insulating coating.
