Abstract

The utility model discloses a potentiometer electric brush structure, which comprises a fixing plate and a plurality of cavities uniformly distributed on the fixing plate; an electric brush is arranged at the inner side of each cavity; the electric brush consists of a strip substrate and an elastic sheet connected with the substrate and extending to the upper side; each electric brush is connected with the fixing plate through two connecting parts; a plurality of locating holes are arranged on the fixing plate; a plurality of electric brushes on the fixing plate form a structure similar to a woven belt; a riveting machine can be inputted in a belt form and riveted with an upper baffle and a lower baffle during assembling the electric brushes and manual feeding one by one of workers is not needed; therefore, the production efficiency is greatly improved; moreover, the riveting quality is stable and the automatic production demand can be satisfied.

Description

A kind of brush structure of potentiometer

Technical field

The utility model belongs to electronic apparatus components and parts technical field, particularly a kind of brush of potentiometer.

Background technology

Potentiometer is widely used in fields such as household electrical appliances, automobile, communication, toy, light of stage and sound equipment, instrument, instrument, and it belongs to fixed carbon resister, mainly plays effects such as menu switching, volume control.

Two big critical components of potentiometer are upper and lower baffle plate and are fixed on the brush on the rubber base; At present common a kind of brush is as depicted in figs. 1 and 2, by the substrate 11 of " C " shape be connected the shell fragment 12 that extends toward upside on the substrate 11 and form, the brush of this structure up, when installing on the lower baffle plate; Mainly be to come riveted through operation manually; One comes production efficiency lower, and the 2nd, the quality of riveted be difficult for to guarantee, adopts also waste material very of " C " shape structure on the other hand.

The utility model content

The purpose of the utility model provides a kind of material-saving and is convenient to the potentiometer brush structure that lathe carries out automatic riveting.

The utility model solves the technical scheme that its technical problem adopted: a kind of brush structure of potentiometer; Comprise fixed head and be evenly distributed on a plurality of die cavities on the fixed head; Be equipped with brush in each die cavity, described brush is by the substrate of strip and be connected the shell fragment that extends toward upside on the substrate and form, and each brush all is connected with fixed head through two connecting portions; Described fixed head is provided with a plurality of location holes, overall structure is little " L " shape.

The beneficial effect of the utility model is: a plurality of brushes on the fixed head constitute the structure of similar braid over braid; When the assembling brush, can carry out riveted with the form input lock seaming machine and the upper and lower baffle plate of strip; No longer need the workman to carry out manual feeding one by one; Production efficiency greatly improves, and the stay in grade of riveted, can satisfy the needs of automated production.And adopt little " L " shape more to help to reduce brush material and saving cost.

Fig. 1 and Fig. 2 are the vertical view and the end views of existing brush;

Fig. 3 and Fig. 4 are the vertical view and the end views of the utility model center brush;

Fig. 5 is the structural representation of the utility model.

Embodiment

Below in conjunction with accompanying drawing the utility model is done further explain.

With reference to Fig. 3, Fig. 4 and shown in Figure 5; The utility model discloses a kind of brush structure of potentiometer; Comprise fixed head 1 and be evenly distributed on a plurality of die cavities 2 on the fixed head 1, be equipped with brush 3 in each die cavity 2, described brush 3 is by the substrate 21 of strip and be connected the shell fragment 22 that extends toward upside on the substrate 21 and form; Each brush 3 all is connected with fixed head 1 through two connecting portions 4; Described fixed head 1 is provided with a plurality of location holes 5, and a plurality of like this brushes 3 constitute the structure of similar braid over braid, overall structure is little " L " shape.

When the assembling brush, can carry out riveted with the form input lock seaming machine and the upper and lower baffle plate of strip, no longer need the workman to carry out manual feeding one by one, production efficiency greatly improves, and the stay in grade of riveted, can satisfy the needs of automated production.

Above-described only is the preferred implementation of the 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 invention design; Can also make some distortion and improvement, these all belong to the protection range of the utility model.

Claims

1. the brush structure of a potentiometer; It is characterized in that: comprise fixed head (1) and be evenly distributed on a plurality of die cavities (2) on the fixed head (1); Be equipped with brush (3) in each die cavity (2); Described brush (3) is by the substrate (21) of strip and be connected substrate (21) and go up the shell fragment (22) that extends toward upside and form, and each brush (3) all is connected with fixed head (1) through two connecting portions (4), and described fixed head (1) is provided with a plurality of location holes (5).
