The invention discloses a grid-type contact plate carbon membrane potentiometer. The grid-type contact plate carbon membrane potentiometer comprises a substrate, a carbon membrane plate, a stationary contact plate, a movable contact plate and a rotating shifting disc, wherein the carbon membrane plate is fixedly installed on the substrate, the rotating shifting disc sleeves the carbon membrane plate, one end of the stationary contact plate and one end of the movably contact plate are respectively connected with the carbon membrane plate, the other end of the stationary contact plate and the other end of the movable contact plate are respectively provided with a contact sheet, the center of each contact sheet has a grid hole, each grid hole is provided with a conductive grid wire, and each conductive grid wire is connected with an annular surface on the inner side of the contact sheet. By adopting the structure, the contact plates of the carbon membrane potentiometer are good in conductivity and excellent in contact performance.
Description
technical field [0001] The invention relates to the field of potentiometers, in particular to a grid type carbon film potentiometer with contacts. Background technique [0002] The carbon film potentiometer is a potentiometer made of a carbon film on the insulating substrate of the resistor. The carbon film potentiometer has simple structure, low noise, good insulation performance, low cost, and simple process. It is one of the most widely used potentiometers at present. However, the long-term use of the carbon film potentiometer will cause the contact piece at the lead end to loosen, which will greatly reduce the contact performance and reduce the service life of the carbon film potentiometer, which will affect the service life of the entire electrical device and affect the normal operation. use. Contents of the invention [0003] The technical problem mainly solved by the present invention is to provide a grid-type carbon film potentiometer with contacts, which can mak...
