例えば絶縁抵抗が1014Ω（オーム）程度を必要
とするリードスイツチの場合、従来の製造方法で
は109〜1012Ω程度に分布し、この要求を満足さ
せることが困難であつた。 For example, in the case of a reed switch which requires an insulation resistance of about 10 14 Ω (ohm), the resistance is distributed in the range of 10 9 to 10 12 Ω using conventional manufacturing methods, making it difficult to satisfy this requirement.
即ち、リード片が封着するガラス管はそれ単体
の絶縁抵抗は通常1015Ω以上あるが、次の理由に
より109〜1012Ω程度になる。 That is, the insulation resistance of the glass tube to which the lead piece is sealed is usually 10 15 Ω or more, but it becomes about 10 9 to 10 12 Ω for the following reason.
１ 外壁伝導
ガラス成分にはアルカリ（Na2O、K2O）が
含まれており、このアルカリが空気中の水分を
吸収し溶解する。そして電圧印加によつてアル
カリがイオン化するためアルカリイオンによる
伝導が起る。1. External wall conduction The glass component contains alkali (Na 2 O, K 2 O), and this alkali absorbs and dissolves moisture in the air. Since the alkali is ionized by voltage application, conduction by the alkali ions occurs.
２ 内壁伝導
外壁伝導と同じ現象でガラス管内に含まれる
水分を吸収しアルカリ伝導が起る。2 Inner wall conduction The same phenomenon as outer wall conduction occurs when moisture contained within the glass tube is absorbed and alkaline conduction occurs.
その他汚れなどによつても絶縁抵抗が下る。 Insulation resistance also decreases due to dirt, etc.
本発明は以上の絶縁抵抗低下を防ぎ、1014Ω

造方法を提供するものである。 The present invention prevents insulation resistance from decreasing further than 10 14 Ω.
The present invention provides a manufacturing method by which the above-mentioned high insulation resistance reed switch can be obtained.
この目的はガラス管表面のアルカリイオンを
塩酸により除去した後、該ガラス管にリード片

イツチの製造方法によつて達成できる。 The purpose of this is to remove alkali ions on the surface of a glass tube with hydrochloric acid, seal a reed piece to the glass tube, and then coat and harden an insulating resin on the outer surface of the glass tube to create a high insulation resistance reed switch. This can be achieved through manufacturing methods.
すなわち、本発明では外壁伝導に関してはア

でアルカリ伝導を防止するものである。 That is, in the present invention, regarding outer wall conduction, conduction caused by alkali ions or dirt in the surrounding air is prevented by removing alkali ions with hydrochloric acid and coating and hardening an insulating resin such as silicone resin on the outer surface of the glass tube. ,
Obtain stable insulation resistance. Regarding inner wall conduction, alkaline conduction is prevented by removing alkali ions on the inner wall surface with hydrochloric acid and increasing the silicon concentration on the inner wall surface.
