Description
Technical field
This utility model belongs to electronic technology field, is specifically related 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 forms.
Between two fixed contacts of resistive element during an additional voltage, change contact on resistive element by rotation or sliding system
Position, between movable contact with fixed contact, just can get the voltage becoming certain relation with movable contact position.Potentiometer
Be commonly used as potentiometer, rheostat and current controller etc., be widely used in measuring instrument, facsimile machine, photocopier, printer with
And the industry such as sensor.
Potentiometer with sliding system is typically by promoting push handle to change position on resistive element, the contact.Repeatedly regulate meeting
Make between contact and resistive element, to produce friction and resistive element is caused damage, simultaneously so that regulation afterwards is not accurate enough, exists
The technical problem positioned it is difficult to during regulation.
Utility model content
The purpose of this utility model is to solve the problems referred to above, it is provided that a kind of potentiometer.
For solving above-mentioned technical problem, the technical solution of the utility model is: a kind of potentiometer, including open-topped shell
Body and the cover plate covering described housing, cover plate is provided with chute, is provided with push handle in chute, and push handle can be moved along the length direction of chute
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 and mates with brush portion
Arcuate groove, brush portion is connected with arcuate groove sliding contact；Being convexly equipped with the limiting stand of annular in described push handle, the diameter of limiting stand is big
In trough width, the upper surface of limiting stand abuts with cover plate lower surface.
Preferably, described push handle is cylindrical.
Preferably, described housing is cuboid.
The beneficial effects of the utility model are: potentiometer provided by the utility model, when resistive element there will be abrasion,
Brush portion is carried out spacing by arcuate groove all the time, stability during holding promotion push handle and the accuracy of location.Limiting stand is used for
Limit the overall displacement at vertical direction of push handle and brush portion, prevent push handle swing in chute, it is ensured that potentiometer is whole simultaneously
The stability of body.

Detailed description of the invention
With specific embodiment, this utility model is described further below in conjunction with the accompanying drawings:
As shown in Figures 1 to 5, a kind of potentiometer of the present utility model, including housing 1 and cover plate 2, housing 1 is cuboid
Shape, its open top forms a cavity, and the bottom of cavity is equipped with resistive element 7, and cover plate 2 lid is encapsulated on housing 1, and cover plate 2 sets
Having the chute 3 of rectangle, chute 3 is relative with the open top of housing 1.Being provided with the push handle 4 of cylinder in chute 3, push handle 4 can be along cunning
The length direction of groove 3 moves；The lower end of push handle 4 is connected with spherical brush portion 5, and resistive element 7 is provided with and mates with brush portion 5
Arcuate groove 8, brush portion 5 is connected with arcuate groove 8 sliding contact.During use, resistive element 7 there will be abrasion, but arcuate groove 8 begins
Eventually brush portion 5 is carried out spacing, stability during holding promotion push handle and the accuracy of location.
As in figure 2 it is shown, be convexly equipped with the limiting stand 6 of annular in push handle 4, the diameter of limiting stand 6 is more than chute 3 width, spacing
The upper surface of platform 6 abuts with cover plate 2 lower surface.Limiting stand 6 is for limiting push handle 4 and brush portion 5 entirety in the position of vertical direction
Move, prevent push handle swing in chute 3 simultaneously, it is ensured that the stability that potentiometer is overall.
As shown in Figure 4, the upper end of push handle 4 is connected with pushing away cap thread, pushes away cap and includes setting female metal cap 9, gold
Belonging to the plastic cap 10 being arranged with cuboid outside cap 9, the width of plastic cap 10 is more than chute 3 width.Metal cap 9 with
Plastic cap 10 is bonding.Pushing away the structure that cap uses metal cap to match with plastic cap, serviceability is good, moderate cost.As
Shown in Fig. 5, the outer wall of plastic cap 10 is provided with continuous print toothed projections, when toothed projections makes staff promote cap not
Easily skid.
Having noctilucent coating on the outer surface of metal cap 9, plastic cap 10 is made up of transparent plastic.Noctilucent coating has
Noctilucent function, it is simple to people use night, and noctilucent coating difficult drop-off.
Cover plate 2 lower end is provided with groove with the contact position of housing 1, is provided with sealing ring 11 in groove.Housing 1 and cover plate 2 lead to
After crossing screw connection, sealing ring 11 is possible to prevent dust, steam etc. to enter inside potentiometer from side.
Offer blind hole on sidewall within housing 1, in blind hole, be filled with desiccant 12.Desiccant has good protection against the tide
Performance, it is ensured that the normal service life of potentiometer.The quantity of blind hole and desiccant can need setting according to actually used.
Those of ordinary skill in the art is it will be appreciated that embodiment described here is to aid in this reality of reader understanding
By novel principle, it should be understood that protection domain of the present utility model is not limited to such special statement and embodiment.
Those of ordinary skill in the art can make various without departing from this practicality according to these technology enlightenment disclosed in this utility model
Other various concrete deformation and combination of novel essence, these deformation and combination are still in protection domain of the present utility model.
