During the tensile test, a fixture is required to clamp and fix one end of the palladium-plated copper wire, and then the palladium-plated copper wire is stretched. Since the outer surface of the palladium-plated copper wire is cylindrical, and the existing fixture clamps the palladium-plated copper wire with a plane during use, the cylindrical shape of the palladium-plated copper wire may be squeezed and deformed, affecting subsequent tests. Therefore, in view of the above situation, there is an urgent need to develop a fixture for the tensile test of palladium-plated copper wire that is convenient to adjust, easy to clamp palladium-plated copper wires with different diameters, and can prevent the palladium-plated copper wire from being squeezed and deformed by using an arc-shaped fixture, so as to overcome the deficiencies in current practical applications and meet current requirements.
