Description
【０００１】[0001]
本考案は、各種エレクトロニクス機器のスイッチ部に使用される接点ゴムスイ ッチ、特にシリコーンゴム入力部の構造に関するものである。 The present invention relates to a contact rubber switch used in a switch section of various electronic devices, and more particularly to a structure of a silicone rubber input section.
【０００２】[0002]
接点ゴムの材料としては、耐熱性、耐寒性に優れ、そして加工性の良いシリコ ーンゴムが多く用いられている。しかしシリコーンゴムは、長期間使用している と、入力部表面より油脂類等を吸収し黄変や膨潤をひき起こすばかりか、導通部 まで浸透し導通不良を来たすこともある。 As the material for the contact rubber, silicone rubber is often used because it has excellent heat resistance, cold resistance, and workability. However, if silicone rubber is used for a long period of time, it not only absorbs oils and fats from the surface of the input section and causes yellowing and swelling, but also penetrates into the conductive section and may cause poor conduction.
【０００３】 またシリコーンゴム入力部の表面は、すべり性が悪いため、摩擦係数を下げて プラスチックスなみのすべり易さ、感触をもったものが以前より望まれていた。[0003] Since the surface of the silicone rubber input portion has poor slipperiness, it has long been desired that the surface of the silicone rubber has a low coefficient of friction and has the smoothness and feel of plastics.
【０００４】[0004]
そこで本考案は、入力部表面の耐油性、耐薬品性を良くし、しかも入力部の表 面のすべり性を良くするために、入力部の表面にプラスチックスの薄い被膜を形 成させるようにしたものである。 Therefore, in the present invention, in order to improve the oil resistance and chemical resistance of the surface of the input part and to improve the slip property of the surface of the input part, a thin film of plastics is formed on the surface of the input part. It was done.
【０００５】 そのために本考案は、ポリパラキシリレン、あるいはその誘導体を、ＣＶＤ（ 化学蒸着）法によりシリコーンゴム入力表面に被膜形成させるようにした。To this end, the present invention is designed to form a film of polyparaxylylene or a derivative thereof on a silicone rubber input surface by a CVD (chemical vapor deposition) method.
【０００６】 本来、ＣＶＤ法は、基材の温度を高温にすることが必要であるが、前記材料を 用いることで、低温で、かつ密着性の秀れた表面被膜の形成が可能となった。Originally, in the CVD method, it is necessary to raise the temperature of the base material, but by using the above-mentioned material, it is possible to form a surface coating having excellent adhesion at low temperature. .
【０００７】[0007]
【実施例１】 シリコーンゴムで成型加工した接点ゴム１の入力部表面２以外をマスキングし て、ＣＶＤ法にてポリパラキシリレンの化学蒸着を行ない、入力部表面に５μの 薄い被膜３を形成させた。[Example 1] The contact rubber 1 molded with silicone rubber was masked except for the surface 2 of the input portion, and chemical vapor deposition of polyparaxylylene was performed by the CVD method to form a thin film 3 of 5μ on the surface of the input portion. Let
【０００８】[0008]
【実施例２】 実施例１と同様にしてポリモノクロロパラキシリレンを用いて入力部表面に５ μの薄い被膜を形成した。Example 2 A thin film of 5 μm was formed on the surface of the input section using polymonochloroparaxylylene in the same manner as in Example 1.
【０００９】[0009]
本考案の実施例１および実施例２で処理した入力部と、このような処理を施さ ない従来例と比較したところ、従来例の摩擦係数をＡＳＴＭ・Ｄ１８９４で測っ たところ１．３であったが、本考案による製品は、実施例１によるものは、０． ２５、実施例２によるものは０．３０であり、入力部表面の摩擦係数が極端に下 がった。そして表面にプラスチックスの感触が得られた。 Comparing the input section processed in Examples 1 and 2 of the present invention with the conventional example not subjected to such processing, the friction coefficient of the conventional example was 1.3 when measured by ASTM D1894. However, the product according to the present invention is the same as that according to the first embodiment. No. 25, that of Example 2 was 0.30, and the friction coefficient on the surface of the input portion was extremely decreased. And the feel of plastics was obtained on the surface.
【００１０】 また従来例と実施例による製品の入力部の上へ、ごま油を浸した綿を置き、６ ０℃零囲気中に放置したところ、従来例のものは、ごま油の浸入が開始したが、 実施例による製品においてはごま油の浸入は起こらなかった。そして当然なこと として黄変や膨潤が生じなかった。Further, when a cotton soaked with sesame oil was placed on the input part of the product according to the conventional example and the example and left in a zero atmosphere at 60 ° C., the sesame oil started to infiltrate in the conventional example. No sesame oil infiltration occurred in the products of the examples. And of course, no yellowing or swelling occurred.
