Technical field
The invention belongs to a kind of resistor, specially a kind of contact resistor of new type auto adjusting.
Background technique
Resistor is general in daily life to be directly known as resistance.It is a current limiting element, after resistance is connect in circuit,
The resistance value of resistor is fixed usually two pins, it can limit the size of current by its institute's chord road.Resistance value cannot
What is changed is known as fixed resister.Resistance value variable referred to as potentiometer or variable resistance.Preferably resistor is linear, i.e.,
It is directly proportional to additional instantaneous voltage by the transient current of resistor.Variable resistance for partial pressure.In exposed resistor body
On, it pressed against one or two removable hard contact.Contact position determines the resistance value between resistor body either end and contact.
End voltage and electric current have determining functional relation, embody the two-terminal device that electric energy is converted into other forms ability, use word
Female R indicates that unit is ohm Ω.Practical devices such as light bulb, heating wire, resistor etc. are represented by resistor element.
Generally and temperature, material, length, it is related that there are also cross-sectional areas for the resistance value size of resistive element, gauge resistor by
The physical quantity that temperature influences size is temperature coefficient, is defined as resistance value changed percentage when temperature is every to increase 1 DEG C.
The main physical characteristics of resistance are that power transformation can be thermal energy, as soon as a dissipative cell can also be said it is, electric current generates interior energy by it.
Resistance usually plays partial pressure, shunting in circuit.For signal, exchange and direct current signal can pass through resistance.
Slide rheostat is a critical elements in circuit, it can change itself by the position of mobile slide plate
Resistance, to play the role of control circuit.In circuit analysis, slide rheostat both can be used as a fixed value resistance,
It can be used as a resistance-changing resistor.Its working principle is to change resistance by changing the length of access circuit part resistive conductor
, to gradually change the size of current in circuit.The resistance wire of slide rheostat is usually fusing point height, and the big nickel chromium triangle of resistance closes
Gold, metallic rod are usually the small metal of resistance, so resistance wire is longer, and resistance is bigger, resistance when one timing of resistance cross section area
Silk is shorter, and resistance is smaller.The composition of slide rheostat in the prior art generally comprises binding post, slide plate, resistance wire, metallic rod
With porcelain cylinder etc., since the resistance wire winding zone on porcelain cylinder is not provided with shield, it is easy by human factor to resistance
It influences, reduces the accuracy and stability of slide rheostat.
Resistor is a current limliting original part, plays the role of adjusting resistance value to transition route.In the prior art using S
Type canoe, when load factor variation, the resistance value of resistor cannot change according to the actual demand of load.Realizing the present invention
During, the inventor finds that the existing technology has at least the following problems: volume is larger, should not process；The resistance value of resistor is not
It can be changed according to the actual demand of load, cause electric current excessive or heating is too fast.
