Title:
SLIDE CONTACT
Document Type and Number:
Japanese Patent JP05174932
Kind Code:
A
Abstract:

PURPOSE: To provide a slide contact having low contact resistance, stability and a long lifetime by alternately arranging noble metal materials each excellent in spring characteristic and noble metal materials each excellent in conductivity.

CONSTITUTION: Tape-like noble metal materials 1 each including 30% by weight of Ag, 35% by weight of Pd, 10% by weight of Au, 10% by weight of Pt, 10% by weight of Cu, and 1% by weight of Zn, having a thickness of 0.08mm and excellent in spring characteristic, and tape-like noble metal materials 2 each including 7.5% by weight of AgCu, having a thickness of 0.08mm and excellent in conductivity are alternately arranged at intervals in the total number of 4, to be thus fixed to a table member tip end portion 3 made of phosphor bronze and having a thickness of 0.1mm by electric resistance welding, followed by molding the tip end at the right angle, thus obtaining an inverted L-shaped slide contact 4. Even if a slide contact test is carried out where permanent set in fatigue or deformation is liable to be generated in a conventional contact, it is possible to prevent permanent set in fatigue or deformation without generating heat or deteriorating a spring characteristic.
