As a method of connecting with a conductor terminal that encloses a part of the insulating coated conductor, a thermocompression bonding method is used as disclosed in Japanese Patent Publication Nos. 50-18940 and 56-28355. In this method, the insulated conductor is covered with an insulating coating so that it cannot be energized. Therefore, there is a U-shape that consists of two parallel side members and a semi-annular member that connects one end of each side member in advance. Insert an insulating coated conductor into the groove of the conductor terminal, sandwich both side members with the upper electrode and the lower electrode, pressurize, and pass a current between the electrodes to heat the U-shaped conductor terminal and insulate with the heat. The coating is carbonized and removed, and the core wire of the insulating coated conductor and the conductor terminal are contacted and connected. In this joining method, a resistance welding machine is used, the energization time is short, the core wire of the insulating coated conductor and the conductor terminal are only in mechanical contact, and are not metallic joints. Therefore, as a means for securing the bonding strength, a connection utilizing crimping by a pressing force is adopted, but it has a drawback that the fatigue strength is low and the electrical characteristics are remarkably deteriorated during long-term use.

った。In the above-mentioned prior art, the joint portion between the insulating coated conductor and the conductor terminal is not sufficient from the viewpoint of metallic joining, so that the mechanical connection strength is low, and vibration and heat cycle are involved. Due to the loosening of the terminals due to such loads, there was a problem with the reliability of the electrical characteristics.
That is, the conventional joining method is effective in removing the insulating coating, but has a problem in achieving highly reliable metallic joining.

That is, the U-shaped conductor terminal is structured to have a holding portion for inserting and holding the insulating coated conductor and an opening end portion such that the groove opening of the conductor terminal can be closed by sandwiching the insulating coated conductor. A bonding aid (brazing material) with a relatively low melting point component is previously attached to the inner surface of the open end of the U-shaped conductor terminal, and the insulation-coated conductor wire is inserted into the holding portion of the U-shaped conductor terminal. Is pressurized and electrically heated to carbonize and insulate the insulation coating of the insulation coating wire, and at the same time, the inner surface of the opening end is metal-bonded through the alloy layer composed of the components of the bonding aid and the components of the conductor terminal. By doing so, it has been found that a strong joint can be realized that joins the insulated wire and the conductor terminal.

めに、二段加熱、加圧方式を採用することが好ましい。It is convenient to use a resistance welding machine capable of performing pressurization and electric heating as the joining device for carrying out the method of joining the insulated coated wire of the present invention. This is because heating and pressing can be done at the same time, and moreover, joining can be done in a short time. In the actual bonding work, the bonding in the atmosphere is convenient for mass production and low-cost bonding. In this case, the shorter the bonding time, the less reaction with oxygen and the better the bonding. In addition, the resistance welding machine preferably employs a two-stage heating / pressurizing method in order to further enhance the reliability of the joint.

The reaction proceeds with the formation of an alloy layer at the interface between the joining aid and the base material of the conductor terminal. Then, the carbonized insulating coating is discharged to the outside of the joint surface by the second step of pressurization and energization, and at the same time, the terminals are brought into contact with each other by pressure through the alloy layers formed at the terminal interface to join them. ..

Here, if the terminal is Cu and a Cu alloy, elements having good reactivity with Cu are Sn, Zn, Au, Ag, P, Pd, etc., but Pb, Bi, etc. are also contained in order to adjust the melting point. It may be. On the contrary, a bonding aid having a low melting point is more convenient because an alloy layer is likely to be formed in the case of heating for a short time.

Therefore, first of all, at least by heating and pressurizing the first step
Heated above 550 ℃. During that time, Pb-50Sn melts and reacts with the Cu base material of the conductor terminal, forming a Cu-Sn alloy layer at the interface with the conductor terminal and unreacted Pb, Sn in the center between the base materials. There is. Next, the PEW carbide is discharged by second-stage heating and pressurization, and the core wires of the insulation-coated conductor wires from which the coating has been removed and the conductor terminals are electrically connected. On the other hand, in the joining of the openings of the conductor terminals, unreacted Pb and Sn are pushed out of the joining surface, and only the Cu-Sn alloy layer remains in the joining portions. The thickness of the alloy layer was approximately 2 μm.
