Description
Technical field
The invention belongs to electronic technology field, and in particular to a kind of linear sliding 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.Current push handle in order to reduce cost be all made of using plastic material, it is wear-resistant
Poor-performing is damaged, if made using metal material, cost is again too high.
Potentiometer is installed in enterprising exercise of various equipment and used, and plays adjustment effect.When potentiometer use environment is moister
When, the oxidation of getting rusty for easily causing some metal parts inside potentiometer after a small amount of moisture, long-time is easily accessible inside it, greatly
The normal service life of big reduction potentiometer, so as to increase use cost.
The content of the invention
Present invention aim to address above mentioned problem, there is provided a kind of linear sliding potentiometer.
In order to solve the above technical problems, the technical scheme is that：A kind of linear sliding potentiometer, including it is open-topped

It is mobile；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 and matched with brush portion
Deep-slotted chip breaker, brush portion is connected with deep-slotted chip breaker sliding contact；The upper end of the push handle is connected with pushing away cap thread, and pushing away cap includes being provided with
The metal cap of internal thread, metal cap overcoat is provided with the plastic cap of cuboid, and the outer wall of plastic cap is provided with continuous
Toothed projections；Offered on the side wall of the enclosure interior and drier is filled with blind hole, blind hole.
Preferably, the width of the plastic cap is more than trough width.
Preferably, the metal cap is Nian Jie with plastic cap.
The beneficial effects of the invention are as follows：Linear sliding potentiometer provided by the present invention, when abrasion occurs in resistive element, arc
Shape groove carries out the accuracy of spacing stability and positioning when keeping promoting push handle to brush portion all the time.Push away cap and use metal
The structure that cap is engaged with plastic cap, performance is good, moderate cost.Blind hole is offered on the side wall of enclosure interior, it is blind
The drier filled in hole has good humidity resistance, it is ensured that the normal service life of potentiometer.

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 linear sliding potentiometer of the invention, including housing 1 and cover plate 2, housing 1 are rectangular
The bodily form, 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, on cover plate 2
Chute 3 provided with rectangle, chute 3 is relative with the open top of housing 1.Push handle 4 provided with cylinder in chute 3, push handle 4 can edge
The length direction movement of chute 3；The lower end of push handle 4 is connected with spherical brush portion 5, and resistive element 7 is provided with and matched with brush portion 5
Deep-slotted chip breaker 8, brush portion 5 is connected with the sliding contact of deep-slotted chip breaker 8.Abrasion, but deep-slotted chip breaker 8 occurs in resistive element 7 during use
All the time the accuracy of spacing stability and positioning when keeping promoting push handle is carried out to brush portion 5.
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
