Title:
PUSH-IN TERMINAL AND ITS MANUFACTURE
Document Type and Number:
Japanese Patent JP3323407
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To accurately force a push-in terminal into a printed circuit board without generating buckling by making the central portion thickness of a terminal push-in portion a slit thinner than that of both end portions so as to plastically deform easily.
SOLUTION: A slit portion 6 is formed in the push-in portion of a push-in terminal 5. The middle portion of the push-in portion is formed into a segmental shape so that the thick thickness portions S2 of both ends are thicker than that of a center thickness portion S1, and has an opening angle θ3 so that the maximum width S3 of the push-in portion is longer than the diameter of a through hole 3 before pushed in to a printed circuit board. The push-in portion is plastically deformed when pushed in to the through hole 3 so as to touch the inner wall of the through hole 3. In this case the opening angle θ3 is changed by plastic deformation. Since the center thickness portion S1 is thinner comparing with both end thickness portions S2, the push-in portion is easily plastically deformed centering its center. Force is applied to the push-in portion from the through hole 3, and when the force of a certain value or more is applied, the same is plastically deformed and is hardened.
