Title: Contact for test contact of electronic part
Inventor: KATAOKA TADAHARU
IPC: G01R31/28
Filed: 1992-05-27
Abstract: PURPOSE:To tear an oxide film on solder, make it hard for dross of solder to adhere and prolong the life of the contact part of a contact, by providing the blade-shaped contact part, the edge of which has about the same direction as the longitudinal one of a contact substrate, at the tip of the springy, plate- form contact substrate fixed at an end thereof to a contact mount. CONSTITUTION:When a contact mount 1 is raised, and also a weight 3 upon a product is lowered, the head of an electronic part P is pressed down by the weight 3, and the blade-shaped contact part 12 of the tip of a contact substrate 10 abuts on the lead L of the part P. Further, when the mount 1 is raised, the substrate 10 becomes a slanting position, because an end 11 of the substrate 10 rises, but the part 12 can not rise higher than the location. Therefore, the part 12 becomes oblique, and the contact position thereof with the lead L moves. The oxide film on the plated solder of the lead L surface is cut, because the move direction is the direction of the edge of the part 12, and both electrically contact. In this state, the electric test can be carried out.
