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, by rotation or sliding system change contact on resistive element
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 typically changes position of the contact on resistive element by promoting push handle.Repeatedly regulation meeting
So that produce friction to cause to damage to resistive element between contact and resistive element, while so that regulation afterwards is not accurate enough, exists
The technical problem for positioning is difficult to during regulation.Current push handle be all made of for reduces cost using plastic material, it is wear-resistant
Poor-performing is damaged, if made using metal material, cost is again too high.
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 is provided with chute, push handle is provided with chute, 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；The upper end of the push handle is connected with cap thread is pushed away, and pushing away cap includes being provided with interior spiral shell
The metal cap of line, metal cap overcoat is provided with the plastic cap of cuboid, and the outer wall of plastic cap is provided with continuous tooth
Shape is raised.
Preferably, the push handle is cylinder.
Preferably, the metal cap is Nian Jie with plastic cap.
The beneficial effects of the invention are as follows：Potentiometer provided by the present invention, when resistive element occurs abrasion, deep-slotted chip breaker begins
The accuracy of spacing stability and positioning when keeping promoting push handle is carried out to brush portion eventually.Push away cap using metal cap with
The structure that plastic cap is engaged, performance is good, moderate cost.

Specific 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.The push handle 4 of cylinder is provided with 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.Resistive element 7 occurs abrasion 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 abuts 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 cap thread is pushed away, 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 is engaged using metal cap 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 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 with the contact position of housing 1, and sealing ring 11 is provided with groove.Housing 1 and cover plate 2 are logical
After crossing mode connects for screw, sealing ring 11 can prevent 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 moistureproof well
Performance, it is ensured that the normal service life of potentiometer.The quantity of blind hole and 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
Those of ordinary skill can according to these technical inspirations disclosed by the invention make it is various do not depart from essence of the invention other are each
