Abstract

The utility model relates to a changeable potentiometer, more particularly a slide potentiometer, comprising a pushing handle and folded-moving sub-component that contacts in sequence, and a carbon sheet main body including a pin, the pushing handle and folded-moving sub-component is in clip matching with on side of the carbon sheet main body, contacts on the pushing handle and folded-moving sub-component is contacted with carbon film on the carbon sheet main body, another side of the carbon sheet main body is provided with a clip connection block which is in clip fixation with the pushing handle and folded-moving sub-component. The utility model has the beneficial effects of good sense of slide and positioning when the pushing handle slides, good blockage intensity, reliable electric performance and long service life. The movement of resistance change can be accomplished only by reciprocating slide of the pushing handle.

Description

Slide potentiometer

Technical field

The utility model relates to a kind of variable potentiometer, especially slide potentiometer.

Background technology

At present, conventional variable potentiometer all is that the direct riveted of carbon plate and terminal uses no plastic process, throw light on brush with push away handle and separate riveted and form, but this common slide potentiometer slip, location hand feeling are relatively poor, stop intensity is less when pushing away handle and sliding into the carbon plate two ends, poor reliability etc. behind the scolding tin.

The utility model content

The utility model is at above-mentioned the deficiencies in the prior art, is intended to release a kind of slip, location hand feeling is good, stop intensity height, and electric property is reliable, the slide potentiometer of long service life.

The technical scheme that its technical problem that solves the utility model adopts is:

Slide potentiometer, comprise the contacted successively carbon plate body that pushes away handle and folding mover assembly and have pin, describedly push away handle and the folding mover assembly blocks mutually with a side of carbon plate body and joins, push away handle and the contact of folding on the mover assembly and contact, be provided with and push away handle and roll over the clamping block that mover assembly fixes mutually in the opposite side of carbon plate body with carbon film on the carbon plate body.

Described clamping block is to be used for and will to push away the spacer of handle and folding mover assembly location.

The described top arrangement that pushes away handle and folding mover assembly has a LED light.

The described top arrangement that pushes away handle and folding mover assembly has a color dot.

The beneficial effect of the utility model slide potentiometer is: slides, location hand feeling is good, and stop intensity height, electric property is reliable, long service life.Only need to move to push away the action that handle can be finished resistance variations.

Embodiment

Referring to figs. 1 through Fig. 6, the utility model is to implement like this:

Slide potentiometer, comprise the contacted successively carbon plate body (20) that pushes away handle and folding mover assembly (10) and have pin, describedly push away handle and folding mover assembly (10) blocks mutually with a side of carbon plate body (20) and joins, the contact (11) that pushes away on handle and folding mover assembly (10) contacts with carbon film on the carbon plate body (20), is provided with and pushes away handle and roll over the clamping block (30) that mover assembly (10) fixes mutually in the opposite side of carbon plate body (20).

Described clamping block (30) will push away the spacer of handle and folding mover assembly (10) location for being used for.

The described top arrangement that pushes away handle and folding mover assembly (10) has a LED light (40), this LED light (40) electric current by the time will luminous indication sliding stroke place the position.

The described top arrangement that pushes away handle and folding mover assembly (10) has a color dot (50).

The above, it only is the preferred embodiment of the utility model slide potentiometer, be not that technical scope of the present utility model is imposed any restrictions, any trickle modification, equivalent variations and modification that every foundation technical spirit of the present utility model is done above example all still belong in the scope of technical solutions of the utility model.

Claims

1. slide potentiometer, comprise the contacted successively carbon plate body (20) that pushes away handle and folding mover assembly (10) and have pin, of the present utility model being characterised in that: describedly push away handle and folding mover assembly (10) blocks mutually with a side of carbon plate body (20) and joins, the contact (11) that pushes away on handle and folding mover assembly (10) contacts with carbon film on the carbon plate body (20), is provided with and pushes away being used for that handle and folding mover assembly (10) fix mutually in the opposite side of carbon plate body (20) and will push away handle and roll over the clamping block (30) that mover assembly (10) is located.

2. slide potentiometer according to claim 1 is characterized in that the described top that pushes away handle and folding mover assembly (10) is provided with a LED light (40).
