Description

Slidable potentiometer

Technical field

The utility model is a kind of related Slidable potentiometer, particularly relates to a kind of Slidable potentiometer structure for having ball Brand-new design has effects that reduce resistance to sliding, improve sliding feel and extend product service life.

Background technique

Potentiometer (Potentiometer), also commonly known as variable resistance (VR, Variable Resistor), are one There are three terminals for kind tool, wherein there are two fixed contact and a self-cleaning contacts, can change sliding end and two via sliding The electronic component of resistance value between fixing end, belongs to passive device, and when use can form different partial pressure ratios, changes sliding point Current potential, thus gain the name.In daily life, the control device for adjusting voltage output signal size, example can be seen often Such as potentiometer.Potentiometer because can by adjustment resistance size, and then control current or voltage size, be applied to many electric appliances On product, common purposes has the functions such as the sensor of control volume, adjustment bright and dark light, position or angle.Potentiometer With a variety of different patterns for changing resistance values, common to have slidingtype and rotary etc., gliding rheostat generally passes through The design of the structure of slide and substrate, slides slide to change the relative position of slide and substrate, and by the brush of slide with The variation of baked fabricated carbons film contact point on substrate, so as to continuously change resistance value and adjust to required resistance sizes.

The common electric potential device stereogram exploded view of Fig. 1 and the common electric potential device group deep cutting diagram of Fig. 2 are please referred to, as seen from the figure often Seeing potentiometer mainly is to be made of substrate A, shell B and slide C, and substrate A extends along its length, and there is a circuit to match Face D is set, there is resistance circuit E to link two side terminal K in circuit configuration face, and shell B has as between fixed substrate A, with substrate A There is the slipping space F extended along its length, there is the sliding slot G extended along its length, sliding slot G to be simultaneously connected to slipping space for top F, slide C are mainly made of pedestal H, the push handle I above pedestal H and the brush J below pedestal H, aforementioned Shell the slipping space F, push handle I that pedestal H is movably arranged in along its length between shell B and substrate A pass through shell sliding slot G, Brush J is then in electrical contact with resistance circuit E on substrate A circuit configuration face D.For common gliding rheostat, usually It is to apply in the volume control of stereo set or level, the power control of other electronic equipments etc..Due to can power transformation in slidingtype In the construction for hindering device, position and the height of slide are limited merely with shell, allows slide can be in moving left and right on resistance circuit, this The mode of shell limitation sledge position and height is used only in kind, and user often has the phenomenon of feel unevenness in moving sliding base, Contact pressure between brush and resistance circuit i.e. on slide is uneven, and the friction between slide and substrate, which can directly react, to be used In the operating handle of person, and since substrate surface is extremely coarse, user is often allowed to feel that operation has some setbacks, being used for a long time can make It is easy to damage to obtain product, influences service life of the products, is its disadvantage.
