Description
Technical field
This utility model relates to electrical and electronic technology field, particularly relates to a kind of slide wire resistor dress
Put.
Background technology
Resistor is the most typically directly referred to as resistance.It is a current limiting element, will
After resistance connects in circuit, the resistance of resistor is fixing usually two pins, and it can
Limit the size of current by its institute's chord road.Resistance is unalterable is referred to as fixed resistance
Device.What resistance was variable is referred to as potentiometer or rheostat.Preferably resistor is linear
, i.e. it is directly proportional to additional instantaneous voltage by the transient current of resistor.For dividing potential drop
Rheostat.On exposed resistive element, pressed against one or two and can move hard contact.
Contact position determines the resistance between resistive element either end and contact.
Terminal voltage and electric current have and determine functional relationship, embody electric energy and are converted into the two of other form abilities
End-apparatus part, represents with letter r, and unit is ohm Ω.Practical devices such as bulb, electric heating
Silk, resistor etc. is all represented by resistor element.
Existing slide wire resistor rubs greatly in sliding process so that resistance wire is susceptible to
Abrasion, and be susceptible to relax in moving process, and easily amass when resistor does not uses
Tired dust, affects the precision of resistance.
