Abstract

The invention discloses a slide rheostat teaching aid. The slide rheostat teaching aid comprises a ceramic cylinder, a slide rheostat support, a sliding piece, a metal rod, connector lugs, a fixing base and a protective cover, wherein the ceramic cylinder and the metal rod are fixedly installed on the slide rheostat support, the sliding piece is arranged between the ceramic cylinder and the metal rod in a connected mode, the connector lugs are arranged at the two ends of the ceramic cylinder and the two ends of the metal rod respectively, support pluggable pins are arranged at the lower end of the slide rheostat support, card slots are formed in the fixing base, the support pluggable pins and the card slots are connected in a pluggable mode so that the slide rheostat support can be fixed to the fixing base, an annular groove is formed in the outer side of the upper end face of the fixing base, the protective cover is connected with the annular groove, and the fixing base is covered with the protective cover. In this way, the slide rheostat teaching aid can provide an operation environment which is more steady and safer for a slide rheostat, so that the slide rheostat teaching aid is safer and more steady when used for experiments.

Description

technical field [0001] The invention relates to the field of experimental teaching aids, in particular to a sliding rheostat teaching aid. Background technique [0002] The sliding rheostat is an important component in the circuit. It can change its own resistance by moving the position of the slide, thus playing the role of controlling the circuit. In circuit analysis, a sliding rheostat can be used as either a fixed value resistor or a variable value resistor. The composition of a sliding rheostat generally includes five parts, including a terminal post, a slider, a resistance wire, a metal rod and a porcelain cylinder. Sliding rheostat is often used in teaching experiments and is a very common experimental tool. However, the traditional sliding rheostat lacks safety and stability design. After long-term experimental use, its accuracy will be affected to a certain extent, and finally affect the experimental results and Teaching Quality. Contents of the invention [00...
