［産業上の利用分野］
本発明は、電子機器のスイッチ部に使用する接点ゴムの
導通部の印刷方法に関するものである。DETAILED DESCRIPTION OF THE INVENTION [Industrial Field of Application] The present invention relates to a method of printing conductive parts of contact rubber used in switch parts of electronic devices.
［従来の技術］
従来の接点ゴムの導通部は、導電ゴム部との加硫接着、
あるいは導電インクを印刷することにより作製されてい
る。[Prior art] The conductive part of conventional contact rubber is made of vulcanized adhesive with the conductive rubber part,
Alternatively, it is produced by printing conductive ink.
［発明が解決しようとする問題点］
導電ゴムは、寿命が優れているという特性を有するが、
導電ゴムシートを導電部の形状に打ち抜く工程や゛、成
型時に金型に合わせて配列する工程が必要なのでコスト
が高く並びに作業性が悪い欠点を有している。[Problems to be solved by the invention] Conductive rubber has the characteristic of having an excellent lifespan, but
Since a process of punching out the conductive rubber sheet into the shape of the conductive part and a process of arranging it according to the mold during molding are required, it has the drawbacks of high cost and poor workability.
また、従来のスクリーン印刷やタンボ印刷法では、膜厚
に限度があるために低抵抗および高寿命の導通部を得る
ことが難しい。In addition, with conventional screen printing and tanbo printing methods, it is difficult to obtain conductive parts with low resistance and long life because there is a limit to the film thickness.
［問題を解決するための手段］
そこで本発明は、溶剤で希釈して液状とした導電インク
を接点ゴム導通部に滴下し、その後に溶剤を蒸発させて
固まらせるようにすることで、厚喚であり、したがって
低抵抗ぞして高寿命の導電部を有する接点ゴムの製造法
を提供せんとするものである。[Means for Solving the Problem] Therefore, the present invention solves the problem by dropping conductive ink diluted with a solvent into a liquid state onto the conductive part of the contact rubber, and then allowing the solvent to evaporate and solidify. Therefore, it is an object of the present invention to provide a method for manufacturing a contact rubber having a conductive part with low resistance and long life.
［実施例］ 導電性インクに揮発性の溶剤を加えて希釈する。[Example] Dilute the conductive ink by adding a volatile solvent.
この希釈した粘度の低いインクを、ロンドの先端に付着

に滴下させ付着させる。付着後のインクは表面張力によ
り、滴下した接点絶縁部にて球状になって留まる。この
滴下したインクが流れ落ちるような場合は、希釈液であ
る溶剤の量を加減してインクの粘度を調整するか、ある
いは滴下するインクの量を調整する。そしてその後、室
温にて放置することで、インク中の揮発性の溶剤が蒸発
され、球状のインクが平面状となり厚膜の導通部が得ら
れる。この導通部の躾の厚さは、インクの希釈濃度を調
整し粘度を変化させることにより稜々調整できる。This diluted ink with low viscosity is applied to the tip of the iron, or it is dripped onto the contact insulating part using an injector or the like. Due to surface tension, the ink after being deposited remains in a spherical shape on the insulating contact portion where it was dropped. If the dropped ink flows down, the viscosity of the ink is adjusted by adjusting the amount of the diluting solvent, or the amount of the dropped ink is adjusted. Thereafter, by leaving the ink at room temperature, the volatile solvent in the ink is evaporated, and the spherical ink becomes planar, resulting in a thick conductive part. The thickness of this conductive portion can be precisely adjusted by adjusting the dilution concentration of the ink and changing the viscosity.
［Ｆｅ明の効果］
このような方法により作製される導通部によれば、従来
の印刷方法等では不可能であった５０μ以上の膜厚でも
容易に作製することができ、したがって低抵抗、耐摩耗
性に優れたものを作製できる。[Effect of Fe light] According to the conductive part produced by such a method, it is possible to easily produce a film thickness of 50μ or more, which was impossible with conventional printing methods, etc., and therefore, it has low resistance and durability. It is possible to create products with excellent wear resistance.
また製作が容易であり、作業性コストの大幅な改善が図
れる。Furthermore, it is easy to manufacture, and workability costs can be significantly improved.
