本発明は、金属を抵抗体とする抵抗器、例え

のを提供することを目的とするものである。DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a resistor using a metal as a resistor, such as a metal film resistor or a wire-wound resistor, and to a resistor that can economically weld the resistor and terminal. The purpose is to provide

はなかつた。 Conventionally, the resistor and terminal in these resistors have been connected by caulking or other methods, or, as in some wire-wound resistors, the resistor and terminal have been connected by spot welding or soldering. Welding was done using low-temperature brazing material, but
None of them could satisfy the contradictory factors of reliability and economy. In other words, in resistors with a contact connection structure such as caulking, when used for a long period of time, an oxide film is formed in the gap between the resistor and the terminal due to the difference in coefficient of thermal expansion, resulting in an increase in contact resistance. This often causes a change in resistance value, and welding by spot welding, soldering, etc. requires an extremely large processing cost, and neither of these methods is satisfactory.

ド線である。 FIGS. 1 and 2 show cross sections of such conventional products.
An example of a conventional wire-wound resistor will be explained based on the figure. In the figure, 1 is an insulating core made of a large number of glass fibers, and 2 is a rod-shaped insulating core made of alumina or the like. In the device shown in Fig. 1, a resistance wire 3 is continuously wound around a focused core 1 of glass fiber, and then the element is cut to a desired size to create individual resistance element pieces. The cap diameter is permanently changed by placing a cap-shaped terminal 4 with an inner diameter slightly larger than the cap diameter and applying pressure from the outer periphery of the cap toward the center using a split chuck with about 4 to 12 sides, thereby making contact between the resistance wire 3 and the cap 4. It is used for joining. 5 is a lead wire attached to this cap-shaped terminal.

合させたものである。 In the case shown in Fig. 2, the rod-shaped insulating winding core 2 is press-fitted into the cap-shaped terminal 4 in advance, and then the resistance wire 3 is wound over the winding core one element at a time, and the terminal of the resistance wire is placed on the surface of the cap-shaped terminal. They are welded and joined using a low melting point brazing material 6 such as solder.
第１図に示す自動化向きの構造を有するものは
接触接合のみである為に経済的効果は大であるが

済的なものである。 The structure shown in Fig. 1, which is suitable for automation, has a large economic effect because only contact bonding is used, but it is unsatisfactory in terms of reliability, especially in terms of long-term deterioration. The structure shown in the figure, which emphasizes reliability, is uneconomical as it requires production of each piece by hand.
そこで本発明は、経済性の効果と信頼性の面の

In the figure, reference numeral 7 denotes a copper plating containing 1 to 15% silver and 4 to 8% phosphorus, which is treated on the surface of the cap-shaped terminal 4. Further, the phosphorus 8 is melted by locally heating the phosphorus-containing silver copper plating 7, and the resistance wire 3
This is the electrode of a plasma spot welding machine for welding the cap-shaped terminal 4 and the cap-shaped terminal 4. During welding, the phosphorus contained in silver and copper plating acts as a ring generator for the oxide film on the surface of the object to be welded, allowing stable welding in the range of about 700°C to 800°C. As for the thickness of this plating layer, a thick plating of 8 to 15 microns is effective.
