Abstract

PURPOSE:To prevent the disconnection of a conductive wire by a method wherein a plurality of edges are arranged on the contact part of an electrode, an elastic sheet is provided on a base plate with which the conductive wire is supported, and the conductive wire is pinched between the contact part and the elastic sheet. CONSTITUTION:A conductive wire is pinched between a moving base 2 and a receiving plate 8 through an elastic sheet 10. A guide shaft 9 is supported by a fixed base 7 in a slidable manner. As a result, even when there is a lump 15 of insulating film layer on the side part of the side in contact with the elastic sheet 10 of a conductive wire 14, the part of the elastic sheet 10 where the lump is in contact shrinks larger than the other part, and the edge 5 is not deeply cut into the conductor on the above-mentioned part. Also, on the part where the insulating film layer is thinly formed, the amount of shrinkage is small, and the edge part 5 can reach the conductor 16.

In other words, if the electrode edge digs into such a thin conductor wire, the conductor will break very easily.
While the electrode edge reliably breaks the insulation coating, it is necessary to accurately set the stopping position of the electrode edge so that damage to the underlying conductor is minimized.However,
In such a thin insulated conductor, the insulating layer is generally thick compared to the thinness of the internal conductor. The thickness of the insulating coating layer is not uniform, with some parts being extremely thick and some parts being extremely thin. Moreover, the difference is large considering the thinness of the conductor. When such a conductor is placed on a fixed base and sandwiched between the electrode and the fixed base, if the insulation coating layer in the part that contacts the fixed base is thick, the internal conductor should be moved away from the fixed base and the electrode placed on it. The robot will move closer to the moving base. On the other hand, if the insulation coating at that portion is thin, the conductor will be separated from the movable base, contrary to the above case. If the conductor gets too close to the moving base, the edges may deeply dig into the conductor and cause large scratches, while if the conductor leaves the moving base, the edges may not reach the conductor.

In this way, with conventional configurations, even if the mechanical precision is improved to accurately set the stopping position of the electrode edge, when using a very thin insulated conductor, it is difficult to deal with the effects of variations in the conductor itself. This resulted in disconnection of the conductor and poor continuity.

The present invention has been made in view of the above problems, and it is an object of the present invention to provide a conductor current-carrying device that can use even very thin insulated conductors without any problems.

Means for Solving the Problems The present invention provides a method in which a plurality of edges are arranged side by side at the contact portion of an electrode, an elastic sheet is provided on a base plate that supports the conducting wire, and the conducting wire is connected between the contact portion and the elastic sheet. I tried to put it in between.

Effect: With the above configuration, it is possible to form a plurality of conduction points in a distributed manner within a rather long section extending in the longitudinal direction of the conducting wire. Therefore, even if the thickness of the insulating coating layer is uneven and the electrode edge cannot reach the internal conductor in some parts, continuity is ensured by the conduction points formed in other parts, and this Therefore, even if the force to pinch the conductor is weak, continuity will be ensured. Also, when the conductor is pinched, the elastic sheet will deform according to the irregularities on the surface of the conductor, and within the above section, the internal The depth of scratches that occur on the conductor can be made uniform.

In other words, even if there is an extremely thick part of the conductor's insulating coating layer facing the base plate, the part of the elastic sheet that touches it will be thick (shrinking), and conversely, even if there is an extremely thin part, the elastic sheet The amount of shrinkage at the part of the elastic sheet that is in contact with it is small. Therefore, for example, if there is an extremely thick part of the insulation coating layer on the part of the insulator-coated conductor facing the base plate, the part of the elastic sheet that is in contact with it will shrink slightly. As described above, the inner conductor shrinks significantly and the inner conductor recedes from the electrode edge by that amount, so that the damage to the inner conductor does not become too large.

また、導線の絶縁被覆層の極度に薄い部分があっても、
その部分では弾性シートの縮みは小さく、電極用エツジ

Also, even if there are extremely thin parts of the conductor's insulation coating,
The shrinkage of the elastic sheet is small in that area, and the electrode edge reaches the internal conductor, providing sufficient conduction.

In this way, the depth of the scratches that occur on the conductor becomes uniform, and reliable continuity is maintained by the multiple electrode edges, so the pinching force on the conductor can be minimized while maintaining reliable continuity. It can minimize damage to the conductor and can be used even with very thin insulated conductors.
