GROUND SPRING, BMA CONNECTOR, AND TEST MEASUREMENT DEVICE

摘要

PROBLEM TO BE SOLVED: To enhance durability of a ground spring for a BMA connector.SOLUTION: A ground spring 100 includes an approximately annular base portion 102 and a plurality of elongate spring fingers 110 extending from the base portion 102. Each of longitudinal axes 120 of the fingers 110 is tilted at about 40 degrees to a reference line 125 extending from a center 130 of the spring 100 to a bottom portion 114 of each finger. This tilt enables elongation of the finger, and thus it becomes hard to exceed an elastic limit in an application of a stress to the finger, thereby enhancing durability.
