Electronic component

Abstract

PROBLEM TO BE SOLVED: To provide a surface mount type electronic component where strength of an external connection part of terminals folded on a same plane as a bottom face of a case is enhanced so as to eliminate defective soldering and to prevent sealing deterioration due to cracking of sealing resin. SOLUTION: A plurality of elements 2-5 and a plurality of terminals 6-9 are contained in a case 1 where a one side face is an opening 1a and the other side face has a terminal insert hole 1b, the surroundings of the opening 1a and the terminal insert hole 1b of the case 1 are sealed by seal resins 12, 13. External connections 6b, 8c of the terminals 6, 8 led out of the opening 1a of the case 1 have a 1st folded part 8c1 folded along the opening 1a of the case 1 and a 2nd folded part 8c2 folded on a same face as the bottom face of the case 1, a resin 14 is applied to a gap between the 1st folded part 8c1 and the sealing resin 12 to fix them. An external connection 7c of the terminal 7 led out of the terminal insert hole 1b of the case 1 has similarly a 3rd folded part 7c1 and a 4th folded part 7c2 and a resin 15 is applied to a gap between the 3rd folded part 7c1 and the sealing resin 13 to fix them.
(57)【要約】 【課題】ケースの底面と同一面上に折り曲げられた端子 の外部接続部の強度を高め、半田付け不良を解消すると ともに、封止樹脂のクラックによる密封性劣化を防止で きる表面実装型の電子部品を得る。 【解決手段】一側面が開口1aを有し、他側面に端子挿 通穴1bを有するケース1に複数の素子2〜5と複数の 端子6〜9とを収納し、ケース1の開口1aと端子挿通 穴1bの周囲とを封止樹脂12,13で封止する。ケー ス1の開口1aから引き出された端子6,8の外部接続 部6b,8cは、ケース1の開口1aに沿って折り曲げ られた第1折曲部8c 1 と、ケース1の底面と同一面上 に折り曲げられた第2折曲部8c 2 とを有し、第1折曲 部8c 1 と封止樹脂12との隙間に樹脂14を流し込ん で固定する。ケース1の端子挿通穴1bから引き出され た端子7の外部接続部7cも同様に、第3折曲部7c 1 と第4折曲部7c 2 とを有し、第3折曲部7c 1 と封止 樹脂13との隙間に樹脂15を流し込んで固定する。
