Abstract

The utility model relates to a sliding paster-type potentiometer, in particular to a small-sized microtype sliding paster-type potentiometer. The utility model comprises a push lever and a carbon plate which are in turn contacted, and a folded active cell with contact points is arranged between the bottom side of the push lever and the carbon plate, and the contact points of the folded active cell are contacted with the carbon film and the silver film of the carbon plate. The folded active cell has four contact points, and the carbon plate is respectively provided with two carbon films and silver films to match with the four contact points of the folded active cell, and the folded active cell can slide right and left while the push lever is slid, and the four contact points of the folded active cell move on the carbon film and the silver film to change the functions of electrical resistance. The carbon-plate printing is that each foot position employs face-side and back-side conducting, and the push lever, the folded active cell and the carbon plate are all engaged and riveted with an outer casing to be fixed. The utility model has the beneficial effects of small size, specific and aesthetic appearance, stable properties, and long service life, which is applicable to the situations which need microtype sliding potentiometers.

Description

The SMD potentiometer of a kind of miniature slip

Technical field

The utility model relates to the SMD potentiometer of a kind of slip, the SMD potentiometer of miniature slip that especially a kind of volume structure is little.

Background technology

At present, Chang Gui slide potentiometer all is to utilize the slip of sliding contact on the carbon plate body that pushes away on the handle that the resistance of resistance is changed.But existing common slide potentiometer is because structural reason is so general volume is bigger, and generally adopts the mode of solder terminal, just inconvenient when some need more small-sized slide potentiometer.The big inconvenience of common slide potentiometer volume etc.

The utility model content

The utility model is at above-mentioned the deficiencies in the prior art, is intended to release that a kind of volume is little, the miniature slip paster potentiometer of unique outlook, attractive in appearance, stable performance, easy to use, long service life.

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

The SMD potentiometer of a kind of miniature slip comprises contacted successively handle and the carbon plate of pushing away, and described pushing away is provided with a folding mover that has a contact between handle bottom side and the carbon plate, and the contact of this folding mover contacts with carbon film, silverskin on the carbon plate.Described folding mover has four contacts, be respectively equipped with on the carbon plate two and the folding mover on four carbon film, silverskin that match in the contact, the folding mover will and then horizontally slip when pushing away handle and being slided, and move on the carbon film on the carbon plate, silverskin to change the function of resistance value four contacts of folding mover.Described carbon plate printing is that positive and negative conducting is adopted in each pin position, above pushes away that handle, folding mover, carbon plate all cooperate with shell, fixes behind the riveted.

The beneficial effects of the utility model are: volume is little, unique outlook, attractive in appearance, stable performance, long service life.Be applicable to the occasion that needs miniature slide potentiometer.

Description of drawings

Below in conjunction with drawings and Examples the utility model is further specified.

Fig. 1 is a decomposition texture schematic diagram of the present utility model;

Fig. 2 is an overall structure schematic diagram of the present utility model.

The drawing reference numeral explanation:

10, push away handle 20, carbon plate 21, carbon film, silverskin

30, folding mover 31, contact 40, shell

Embodiment

Referring to figs. 1 through Fig. 4, the utility model is to implement like this:

A kind of miniature slide potentiometer, comprise contacted successively handle (10) and the carbon plate (20) of pushing away, described pushing away is provided with a folding mover (30) that has a contact (31) between handle (10) bottom side and the carbon plate (20), the contact (31) of this folding mover (30) contacts with carbon film, silverskin (21) on the carbon plate (20).

Described folding mover (30) has four contacts (31), is respectively equipped with the carbon film, the silverskin (21) that match in two folding mover (30) last four contacts (31) on the carbon plate (20).

The printing of described miniature slide potentiometer carbon plate is that positive and negative conducting is adopted in each pin position, pushes away that handle (10), folding mover (30), carbon plate (20) all cooperate with shell (40), fixes behind the riveted.

The above, it only is the preferred embodiment of a kind of miniature slide potentiometer of the utility model, 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.
