Description
Technical field
The invention belongs to a kind of resistor, specially a kind of contact resistor of new type auto regulation.
Background technology
Resistor is typically directly referred to as resistance in daily life.It is a current limiting element, after resistance is connect 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 can not
Changed is referred to as fixed resister.What resistance was variable is referred to as potentiometer or variable resistance.Preferably resistor be linear, i.e.,
It is directly proportional to additional instantaneous voltage by the transient current of resistor.Variable resistance for partial pressure.In exposed resistive element
On, pressed against one or two removable hard contact.Contact position determines the resistance between resistive element either end and contact.
Terminal voltage has determination functional relation with electric current, embodies the two-terminal device that electric energy is converted into other forms ability, uses word
Representing, unit is ohm Ω to female R.Practical devices such as bulb, heating wire, resistor etc. are all represented by resistor element.
Typically and temperature, material, also length, cross-sectional area are relevant, and gauge resistor is received for the resistance value size of resistive element
The physical quantity of temperature impact size is temperature coefficient, and which is defined as the percentage that resistance value changes when temperature often raises 1 DEG C.
It is heat energy that the main physical characteristics of resistance are change electric energy, can also say that it is a dissipative cell, and electric current just produces interior energy through it.
Resistance generally plays partial pressure, shunting in circuit.For signal, exchange can pass through resistance with direct current signal.
Slide rheostat is critical elements in circuit, and it can change itself by the position of mobile slide plate
Resistance, so as to play a part of control circuit.In circuit analysis, slide rheostat both can as a fixed value resistance,
Can be used as a resistance-changing resistor.Its operation principle is to change resistance by changing the length for accessing circuit part resistive conductor
, so as to gradually change the size of current in circuit.The resistance wire of slide rheostat is usually that fusing point is high, and the big nickel chromium triangle of resistance is closed
Gold, metallic rod are usually the little metal of resistance, so when one timing of resistance cross section area, resistance wire are longer, resistance is bigger, resistance
Silk is shorter, and resistance is less.The composition of slide rheostat of the prior art generally comprises binding post, slide plate, resistance wire, metallic rod
With porcelain cylinder etc., as the resistance wire winding zone on porcelain cylinder is not provided with protective cover, easily by human factor to resistance
Impact, reduces accuracy and the stability of slide rheostat.
Resistor is a current limliting original paper, and transition circuit is played a part of to adjust resistance.S is used in prior art
Type canoe, when load factor changes, the resistance of resistor can not change according to the actual demand of load.Realizing the present invention
During, inventor has found that prior art at least has problems with：Volume is larger, should not process；The resistance of resistor is not
Can be changed according to the actual demand of load, cause electric current excessive or heat up too fast.
