If three electrodes are used as described above, even if there is a coated conductive member between the first and second electrodes, the current from the first electrode to the second electrode via the coated wire and the terminal is prevented. In addition, the electric insulating film can be broken by heat generated between the first and third electrodes. Therefore, there is an advantage that the degree of freedom in the shape of the uncoated conductive member is high when the uncoated conductive member that is not covered with the electric insulating film and the coated conductive member are joined. When the third electrode is not used, a portion of the uncoated conductive member to be joined to the coated conductive member is bent into a U-shape to make contact with the two electrodes, and a contact electric resistance of a contact portion between the uncoated conductive member and the electrode is formed. It is necessary to melt the electric insulating film due to the heat generated by the non-conductive member, so that the degree of freedom in the shape of the uncoated conductive member is low. Since the insulating film can be melted, the uncoated conductive member does not have to be curved in a U-shape.

SUMMARY OF THE INVENTION In view of the above circumstances, it is an object of the present invention to provide an apparatus for bonding covered conductive members having three electrodes and having a compact configuration. According to the present invention, a coated conductive member bonding apparatus, an electrode pair for a coated conductive member bonding apparatus, and an electrode for resistance welding of the following embodiments can be obtained. As in the case of the claims, each aspect is divided into sections, each section is numbered, and if necessary, the other sections are cited in a form in which the numbers are cited. This is to clarify the possibility of combining the features described in each section. (1) a first electrode and a second electrode provided to face each other are approached and separated from each other by an electrode moving device, and a third electrode is provided in a state of being in contact with the first electrode;
In a coated conductive member joining apparatus, a heating current is supplied from a heating power source between a first electrode and a third electrode, and then a welding current is supplied from a welding power source between the first electrode and the second electrode. One of the first and third electrodes is coaxially opposed to the second electrode, and the other of the first and third electrodes has a main body extending in parallel with the one, and a tip extending from the main body. And a contact portion extending in a direction intersecting with one axial direction and contacting one end thereof. In the bonding apparatus of this aspect, the power source for heat generation and the power source for welding may be provided exclusively, or may be shared. In the former case, a heating power supply is connected to the first electrode and the third electrode, and the welding power supplies are the first and third electrodes.
One of the third electrodes is connected to the second electrode. In the latter case, the third electrode may be electrically connected to the second electrode at all times. In any case, a current flows between the first electrode and the third electrode when the electric insulating film of the coated conductive member is melted, and the first and third electrodes directly contact the conductive member during resistance welding. Therefore, it is desirable that the electrodes are connected to the heat generating power source and the welding power source so that the current flows to the conductive member without passing through the other. The plurality of conductive members joined by the coated conductive member joining apparatus of this aspect are covered conductive members at least one of which is covered with an electric insulating film. The first, second and third electrodes are connected to the first and third electrodes by the second
The second electrode may be moved toward and away from the first and third electrodes, or both may be moved toward and away from the electrodes. The contact portion may extend from the tip of the main body in a direction orthogonal to one axial direction of the first and third electrodes, or may extend in a direction other than the orthogonal direction.
The extension direction may be determined according to the shape of one end of the first and third electrodes. In the bonding apparatus of this aspect, one of the first and third electrodes is coaxially opposed to the second electrode, and the other is provided along one, so that the other intersects with one axial direction from one. It does not protrude in the direction in which the first and third electrodes are arranged, and the space for disposing the first and third electrodes is small. Therefore, the effect of improving the degree of freedom in designing products and devices having a conductive member joined by the coated conductive member joining device of the present embodiment is obtained. (2) The third electrode is coaxially opposed to the second electrode, and a cylindrical first electrode having a bottom is provided outside the third electrode, and the bottom is in contact with the tip end surface of the third electrode. The covering conductive member joining device according to the above mode (1) is disposed with a radial gap between the outer peripheral surface of the third electrode and the radial direction. In this aspect, the bottom of the first electrode forms a contact portion, and the cylindrical portion forms a main body. At the time of joining, the outer surface of the bottom portion of the first electrode is brought into contact with the conductive member, and if a heating current is supplied from a heating power supply, the contact portion between the bottom portion of the first electrode and the tip end surface of the third electrode is in contact electric contact. Heat is generated by the resistance, and the electric insulating film of the coated conductive member is melted. Although the cylindrical portion and the third electrode extend in parallel with each other, there is a radial gap between the inner peripheral surface and the outer peripheral surface of both, so that the inner peripheral surface of the cylindrical portion and the outer peripheral surface of the third electrode are provided. Does not generate heat, generates heat intensively at the contact portion between the bottom of the first electrode and the tip end surface of the third electrode, and quickly melts the electrical insulating film. Since the first electrode has a cylindrical portion, even if it is long in the axial direction, the rigidity is not insufficient and a large amount of current can be supplied. (3) The third electrode is coaxially opposed to the second electrode, and the first electrode has at least one main body extending in parallel to the third electrode, and an axis of the third electrode from the main body. And a plate-shaped contact portion extending in a direction perpendicular to the direction and contacting the tip end surface of the third electrode.
In the case where there are a plurality of body portions, their tips are connected to each other by a contact portion, and the outer surface of the contact portion (the surface opposite to the side contacting the tip surface of the third electrode) is a conductive member. Desirably, they are brought into contact. The cross-sectional shape of the first electrode in the direction orthogonal to the axial direction of the third electrode can be made smaller than when the first electrode has a cylindrical portion,
It is easy to avoid interference of the conductive member to be joined with the peripheral member, and the degree of freedom in designing the peripheral member can be further improved. (4) Two main body portions of the first electrode are provided at axially symmetric positions with the axis of the third electrode as a symmetric axis, and the contact portions connect the tips of the two main body portions. (3) The coated conductive member bonding apparatus according to the above (3). Only the tip of the bottomed cylindrical first electrode according to the above item (2) is the same as the above item (3) or
The form described in (4) may be adopted. If you do that,
For example, when there is a member that prevents the arrangement of the first and third electrodes only in the vicinity of the conductive member to be joined, it is possible to avoid interference with the member. If only the tip is in the form described in paragraph (3) or (4), the portion on the base end side opposite to the tip can be cylindrical, which results in insufficient current supply or rigidity. Can be avoided and interference with peripheral members can be avoided. (5) The first electrode is coaxially opposed to the second electrode, and the third electrode has a main body extending parallel to the first electrode, and an axial direction of the first electrode from a tip of the main body. And a contact portion extending in the direction intersecting and contacting the side surface of the tip of the first electrode. In this embodiment, at the time of bonding, the first electrode is brought into contact with the conductive member, and the first current is supplied to the first and third electrodes, so that the first electrode is in contact with the first and third electrodes.
The side surface of the electrode and the contact portion of the third electrode generate heat due to contact electric resistance, and melt the electric insulating film. In a state where the contact portion of the third electrode is in contact with the side surface of the first electrode, it is desirable that the main body portion is slightly elastically deformed to generate an elastic force for pressing the contact portion against the first electrode. (6) another including a linear electrode, a main body extending parallel to the electrode, and a contact portion extending from a tip of the main body in a direction intersecting the longitudinal direction of the electrode and contacting the tip of the electrode. And an electrode pair for a coated conductive member joining apparatus. Regarding the electrode pair of this embodiment, it is possible to adopt the features relating to the first and third electrodes of the bonding apparatus described in the respective items (1) to (5), and the first and third electrodes described in those items. The effect obtained for is also obtained for the electrode pair of this embodiment. (7) The main body portion of the another electrode is a cylindrical portion that can be fitted outside the linear electrode with a radial gap therebetween,
The electrode pair according to item (6), wherein the contact portion is a disk portion that closes a distal end opening of the cylindrical portion. (8) An electrode for resistance welding having a cylindrical shape with a bottom and a bottom.
