JPS6411351A - Package for sealing circuit component - Google Patents

Abstract

PURPOSE:To eliminate the need for connecting earth terminals with silver solder and make a package lighter without using metal frames by using a base wherein the earth terminals are mounted at an electrode plate of a package base and further, by sealing earth and lead terminals, thereby forming a book-type body made of insulating materials around the above base. CONSTITUTION:A base 21 is equipped with a flat plate type electrode plate 22 and a number of earth terminals 5 are extended to the outside and are connected with a plate 24. A lead terminal 3 extends in the direction of the electrode plate 22 from the plate 24 and a pointed end 32 is formed into a sectional U-shape and allows circuit components 30 to be easily connected to the lead terminal 3. The other pointed end 51 of the terminal 5 has the same functions. A book-type body 26 made of insulating materials 4 is formed around the base 21 and it not only seals terminals 5 and 3 but also makes this package form an air-tight space 28 wherein circuit components are sealed. When the package is used, the plate 24 is cut-off from the terminals 5 and 3 so that mutual contact is cut between the above terminals and plate 24 and mounting of the circuit components 30 into the air-tight space 28 allows the circuit components 30 to be connected to the terminals 5 and 3. After that, the package is pressed using pressure after putting a lid 8 on it.
