Description
Technical field
The invention belongs to electronic technology field, and in particular to a kind of potentiometer.
Background technology
Potentiometer is a kind of adjustable electronic component, and it is rotated by a resistive element and one or sliding system is constituted.
When an additional voltage between two fixed contacts of resistive element, contact is changed on resistive element by rotation or sliding system
Position, between movable contact and fixed contact just can obtain one with movable contact position into certain relation voltage.Potentiometer
Be commonly used as divider, rheostat and current controller etc., be widely used in measuring instrument, facsimile machine, duplicator, printer with
And the industry such as sensor.
Potentiometer with sliding system is general to change position of the contact on resistive element by promoting push handle.Repeatedly regulation meeting
So that friction is produced between contact and resistive element causes damage to resistive element, simultaneously so that regulation afterwards is not accurate enough, exists
It is difficult to the technical problem positioned during regulation.
The content of the invention
Present invention aim to address above mentioned problem, there is provided a kind of potentiometer.
In order to solve the above technical problems, the technical scheme is that：A kind of potentiometer, including open-topped housing and
The cover plate of the housing is covered, cover plate, which is provided with chute, chute, is provided with push handle, and push handle can be moved along the length direction of chute；
The lower end of push handle is connected with spherical brush portion, and enclosure interior is provided with resistive element, and resistive element is provided with the arc matched with brush portion
Shape groove, brush portion is connected with deep-slotted chip breaker sliding contact；Be convexly equipped with the push handle annular limiting stand, limiting stand with diameter greater than
Trough width, the upper surface of limiting stand is abutted with cover plate lower surface.
Preferably, the push handle is cylinder.
Preferably, the housing is cuboid.
The beneficial effects of the invention are as follows：Potentiometer provided by the present invention, when abrasion occurs in resistive element, deep-slotted chip breaker begins
The accuracy of spacing stability and positioning when keeping promoting push handle is carried out to brush portion eventually.Limiting stand is used to limit push handle
With brush portion integrally in the displacement of vertical direction, while preventing swing of the push handle in chute, it is ensured that the overall stabilization of potentiometer
Property.

Embodiment
The present invention is described further with specific embodiment below in conjunction with the accompanying drawings：
As shown in Figures 1 to 5, a kind of potentiometer of the invention, including housing 1 and cover plate 2, housing 1 are cuboid, its
Open top forms a cavity, and the bottom of cavity is equipped with resistive element 7, and the lid of cover plate 2 is encapsulated on housing 1, and cover plate 2 is provided with rectangle
Chute 3, chute 3 is relative with the open top of housing 1.Push handle 4 provided with cylinder in chute 3, push handle 4 can be along chute 3
Length direction is moved；The lower end of push handle 4 is connected with spherical brush portion 5, and resistive element 7 is provided with the arc matched with brush portion 5
Groove 8, brush portion 5 is connected with the sliding contact of deep-slotted chip breaker 8.Abrasion occurs in resistive element 7 during use, but deep-slotted chip breaker 8 is right all the time
Brush portion 5 carries out the accuracy of spacing stability and positioning when keeping promoting push handle.
As shown in Fig. 2 be convexly equipped with push handle 4 annular limiting stand 6, limiting stand 6 with diameter greater than the width of chute 3, it is spacing
The upper surface of platform 6 is abutted with the lower surface of cover plate 2.Limiting stand 6 is used to limit push handle 4 and brush portion 5 is overall in the position of vertical direction
Move, while preventing swing of the push handle in chute 3, it is ensured that the overall stability of potentiometer.
As shown in figure 4, the upper end of push handle 4 is connected with pushing away cap thread, pushing away cap includes setting female metal cap 9, gold
The plastic cap 10 of cuboid is arranged with outside category cap 9, the width of plastic cap 10 is more than the width of chute 3.Metal cap 9 with
Plastic cap 10 is bonded.The structure that cap uses metal cap to be engaged with plastic cap is pushed away, performance is good, moderate cost.Such as
Shown in Fig. 5, the outer wall of plastic cap 10 is provided with continuous toothed projections, when toothed projections cause the staff to push away cap not
Easily skid.
There is noctilucent coating, plastic cap 10 is made up of transparent plastic on the outer surface of metal cap 9.Noctilucent coating has
Noctilucent function, is easy to people to use at night, and noctilucent coating is difficult for drop-off.
The lower end of cover plate 2 is provided with groove, groove with the contact position of housing 1 and is provided with sealing ring 11.Housing 1 and cover plate 2 are logical
Cross after mode connects for screw, sealing ring 11 can prevent that dust, steam etc. from entering inside potentiometer from side.
Offered on side wall inside housing 1 and drier 12 is filled with blind hole, blind hole.Drier has good moistureproof
Performance, it is ensured that the normal service life of potentiometer.Blind hole and the quantity of drier can need setting according to actually used.
One of ordinary skill in the art will be appreciated that embodiment described here is to aid in reader and understands this hair
Bright principle, it should be understood that protection scope of the present invention is not limited to such especially statement and embodiment.This area
