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, 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.
Potentiometer is installed in enterprising enforcement of various equipment and uses, and plays adjustment effect.The sealing property and current potential of potentiometer
The service life of device is closely bound up, and sealing property is bad, and dust, steam etc. can be caused to enter inside potentiometer, reduces potentiometer
Service life.
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 open-topped shell
Body and the cover plate for covering the housing, cover plate are provided with chute, and push handle is provided with chute, and push handle can be moved along the length direction of chute
It is dynamic；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 what is matched with brush portion
Deep-slotted chip breaker, brush portion is connected with deep-slotted chip breaker sliding contact；The limiting stand of annular is convexly equipped with the push handle, the diameter of limiting stand is big
In trough width, the upper surface of limiting stand abuts with cover plate lower surface；The cover plate lower end is provided with groove with the contact position of housing,
Sealing ring is installed in groove.
Preferably, the housing is cuboid.
Preferably, the housing and cover plate are connected by screw.
The beneficial effects of the invention are as follows：Linear sliding potentiometer provided by the present invention, when resistive element occurs abrasion, arc
Groove carries out the accuracy of spacing stability and positioning when keeping promoting push handle to brush portion all the time.Limiting stand is used to limit
The overall displacement in vertical direction of push handle and brush portion, while preventing swing of the push handle in chute, it is ensured that potentiometer entirety
Stability.After housing and cover plate are connected by screw, sealing ring can prevent dust, steam etc. from entering in potentiometer from side
Portion.

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 linear sliding potentiometer of the invention, including housing 1 and cover plate 2, housing 1 are cuboid
Shape, 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, is set on cover plate 2
There is the chute 3 of rectangle, 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 cunning
The length direction movement of groove 3；The lower end of push handle 4 is connected with spherical brush portion 5, and resistive element 7 is provided with what is 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.Resistive element 7 occurs abrasion during use, but deep-slotted chip breaker 8 begins
The accuracy of spacing stability and positioning when keeping promoting push handle is carried out to brush portion 5 eventually.
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
