TEST PIECE MOLD FOR WITH STAND VOLTAGE OF ULTRASONIC SENSOR DEVICE

摘要

The present invention relates to a specimen molding mold for measuring the breakdown voltage of an ultrasonic sensor.;As a configuration, the present invention, in the production of the dielectric breakdown test specimen of the mold in the mold consisting of the upper body 330, the body portion 320 and the lower body, the lower body 310 is rounded the center of the upper surface Characterized by protruding into shape.;According to such a structure, it is easy to manufacture the disk-shaped test piece of uniform dimension in which the center part of one side is recessed, and it can reduce the waste of time which it produces, and can obtain the accurate measurement value of the dielectric breakdown test.
