Description

A kind of new linear sliding potentiometer
Technical field
The invention belongs to electronic technology field, and in particular to a kind of new 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 by promoting push handle to change position of the contact on resistive element.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.
The content of the invention
Present invention aim to address above mentioned problem, there is provided a kind of new linear sliding potentiometer.
In order to solve the above technical problems, the technical scheme is that:A kind of new linear sliding potentiometer, including open top Housing and cover the cover plate of the housing, cover plate, which is provided with chute, chute, is provided with push handle, and push handle can be along the length side of chute To movement;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 brush portion The deep-slotted chip breaker matched somebody with somebody, brush portion is connected with deep-slotted chip breaker sliding contact;Be convexly equipped with the push handle annular limiting stand, limiting stand it is straight Footpath is more than trough width, and the upper surface of limiting stand is abutted with cover plate lower surface;The upper end of the push handle is connected with pushing away cap thread, is pushed away Cap includes setting female metal cap, and metal cap overcoat is provided with the plastic cap of cuboid, the outer wall of plastic cap It is provided with continuous toothed projections.
Preferably, the width of the plastic cap is more than trough width.
Preferably, the housing and cover plate are connected by screw.
The beneficial effects of the invention are as follows:New linear sliding potentiometer provided by the present invention, when abrasion occurs in resistive element, Deep-slotted chip breaker carries out the accuracy of spacing stability and positioning when keeping promoting push handle to brush portion all the time.Limiting stand is used for The overall displacement in vertical direction of push handle and brush portion is limited, while preventing swing of the push handle in chute, it is ensured that potentiometer is whole The stability of body.The structure that cap uses metal cap to be engaged with plastic cap is pushed away, performance is good, moderate cost.

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 new linear sliding potentiometer of the invention, including housing 1 and cover plate 2, housing 1 is length Cube 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, cover plate 2 The chute 3 of rectangle is provided with, chute 3 is relative with the open top of housing 1.Push handle 4 provided with cylinder in chute 3, push handle 4 can Moved along the length direction 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 5, brush portion The deep-slotted chip breaker 8 matched somebody with somebody, brush portion 5 is connected with the sliding contact of deep-slotted chip breaker 8.Abrasion, but deep-slotted chip breaker occurs in resistive element 7 during use 8 carry out the accuracy of spacing stability and positioning when keeping promoting push handle to brush portion 5 all the time.
As shown in Fig. 2 being convexly equipped with the limiting stand 6 of annular in push handle 4, the diameter of limiting stand 6 is more than the width of chute 3, 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.
