FEEDTHROUGH TYPE CAPACITOR

摘要

PURPOSE: To improve work efficiency and productivity by economizing the parts of capacitor and production processes by integrating upper and lower insulating cases surrounding a ceramic disc. CONSTITUTION: A pair of separate surface electrodes 212 and 222 having corresponding through-holes are provided on the upper surface of ceramic disc 200, and a common surface electrode 230 having a correspondent through-hole is provided on its lower surface. An insulating case 400 is made elliptical, forming both the terminals semicircular so as to be communicated with a through-hole 320 on a ground board 300, and its upper and lower cases 410 and 420 are formed integrally with the ground board 300 by injection. A pair of through- conductors 500 and 600 are formed, along with a pair of through-holes 210 and 220 on the ceramic disc 200. The through-conductors 500 and 600 are inserted into the through-holes 220 and 210 on the ceramic disc 200 and an elliptical hole 330 on the ground board 300.
