Abstract

The utility model discloses a slidable potentiometer, which comprises a reed, a slide sheet, a carbon diaphragm, a push handle, a carbon brush and an outer casing. The push handle is connected with the carbon brush, a slide groove for the push handle to slide is arranged on the top face of the outer casing, the reed is an arc-shaped elongated metal sheet with a square hole, and four supporting legs turning up toward two sides are arranged at four corners of the reed. The slidable potentiometer is characterized in that upward positioning projections are arranged at the supporting legs of the reed, positioning notches corresponding to the positioning projections are arranged on the slide sheet, and positioning grooves corresponding to the positioning projections are arranged on the plane of the outer casing where the slide groove locates. An existing positioning device with a spring and a steel ball is substituted by a reed positioning device, and accordingly, the slidable potentiometer is simpler in structure and lower in production cost, and assembling efficiency of the slidable potentiometer can be increased while processing cost thereof can be reduced.

Description

A kind of slidingtype potentiometer

Technical field

The utility model belongs to the carbon-film potentiometer field, more specifically relates to a kind of slidingtype potentiometer.

Background technology

The slidingtype potentiometer plays the important function of control volume, wherein its positioning action of the positioner of potentiometer in equipment such as sound equipment, sound console.Positioner adopts spring to add the location technology (as shown in Figure 3) of steel ball more in the existing technology, yet because the locator volume is less, cost is also higher relatively so the required precision of corresponding with it spring and steel ball is higher, so production cost is higher relatively, thereby cause the production cost of potentiometer also higher, and because potentiometer spring and the too small hand assembled that needs of steel ball, and the extremely low processing cost that has increased potentiometer especially greatly of installation effectiveness.

The utility model content

In order to address the above problem, the purpose of this utility model is to provide a kind of slidingtype potentiometer, can reduce production costs, and increases installation effectiveness and cuts down finished cost.

For achieving the above object, the technical scheme that the utility model adopted is: a kind of slidingtype potentiometer, comprise reed, slide plate, carbon film plate, push away handle, carbon brush and shell, pushing away handle is connected with carbon brush, outer casing top surface is provided with for pushing away the chute that handle slides, reed is the arc long-bar metal sheet that has square hole, and four jiaos of places of reed are provided with the support leg to the both sides perk, and the support leg place of described reed is provided with positioning convex upwards; Corresponding positioning convex is provided with locating notch on the slide plate; On shell plane, chute place, corresponding each positioning convex is provided with location notch.

More excellent, described location notch is located on the mobile alignment of positioning convex.

After adopting technique scheme, its beneficial effect is: replace existing spring to add the positioner of steel ball with the reed location, more the simple production cost is lower for structure, can also improve packaging efficiency and cut down finished cost.

Embodiment

Below in conjunction with accompanying drawing the utility model is described in further detail.

As depicted in figs. 1 and 2, a kind of slidingtype potentiometer, comprise reed 3, slide plate 2, carbon film plate 6, push away handle 4, carbon brush 5 and shell 1, pushing away handle 4 is connected with carbon brush 5, shell 1 end face is provided with for pushing away the chute 11 that handle 4 slides, reed 3 is for having the arc long-bar metal sheet of square hole, and 3 four jiaos of places of reed are provided with the support leg to the both sides perk, and the support leg place of described reed is provided with positioning convex 31 upwards; Corresponding positioning convex 31 is provided with locating notch 21 on the slide plate 2.On shell 1 plane, chute place, corresponding each positioning convex 31 is provided with location notch 12, and location notch 12 is located on the mobile alignment of positioning convex 31.Push away handle 4 and embed chute from inside to outside, carbon film plate 6 is connected and fixed at shell 1 end opening place with shell 1, reed 3 and slide plate 2 are enclosed within to push away on the handle 4 and be clipped in and push away between handle 4 and shell 1 inwall, slide plate 2 is located near the inwall direction, slide plate 2 plays the abrasionproof effect and makes and push away handle 4 and move more smooth and easy, reed 3 produces tension force and makes and be connected the carbon brush 5 that pushes away on the handle 4 and contact tightr with carbon film plate 6 and can not produce uncontrolled slip, on at least one support leg of reed 3, be provided with positioning convex 31, leg pushes to shell 1 inwall always because reed 3 is in the squeezed state support always, the support leg of band positioning convex 31 acts directly on shell 1 inwall by the locating notch on the slide plate 2 21, when projection movement arrives location notch 12 positions, positioning convex 31 just can embed location notch 12 under the effect of power, push away handle 4 generation stagnation senses and be convenient to the location, replace existing spring to add the positioner of steel ball with reed 3 positioners, more the simple production cost is lower for structure, also improve packaging efficiency greatly and cut down finished cost, the utility model is applicable to that generally sliding stroke is 15mm and the above potentiometer of 15mm.

Above-described only is preferred implementation of the present utility model; should be pointed out that for the person of ordinary skill of the art, under the prerequisite that does not break away from the utility model creation design; can also make some distortion and improvement, these all belong to protection range of the present utility model.
