扰性变阻片

Flexible rheostat

Abstract

The utility model discloses a flexible rheostat which comprises a substrate, at least one resistive film, at least one left electrode film and at least one right electrode film. The resistive films, the left electrode films and the right electrode films are arranged on the substrate, left ends of the resistive films are in contact with the left electrode films, right ends of the resistive films are in contact with the right electrode films, and the substrate is a flexible substrate. Owing to the flexible substrate, the flexible rheostat can be tilted and bent, and is beneficial to assembling a product, and the application range of the product is further enlarged. The flexible rheostat has the advantages of high abrasion resistance, good linearity, long service life and the like.
本实用新型公开了一种扰性变阻片,包括基板、至少一个电阻膜层、至少一个左电极膜层和至少一个右电极膜层,所述电阻膜层、左电极和右电极设置在基板上,所述电阻膜层的左端与左电极膜层相接触,电阻膜层的右端与右电极膜层相接触,所述基板为挠性基板。采用挠性基板,使本实用新型获得了可以典翘、折弯的特点,有利于产品装配,进一步扩大产品的适用范围。具有耐磨性强、线性好、寿命长等特点。
