Definitions
- the invention relates to an arrangement for contacting resistance tracks.
- a potentiometer is known with a circular housing lower part designed as a plastic injection-molded part, in which a wound, circular-arc-shaped resistance body is seated. Terminal contact pins are injected into the lower part of the housing. Contact pieces designed as stamped parts made of sheet metal are connected to the resistance body and the connecting contact pins and are seated in recesses in the lower housing part.
- a cover part consists of a ductile outer part in the form of a sheet metal part and a rubber-elastic layer sitting in this ductile outer part. The cover part is connected to the lower housing part by flanging. The rubber-elastic layer provides a seal. In addition, the gummi el asti see layer on the side facing away from the contact pieces on the resistance body. As a result, the resistance body is held in the housing.
- the invention is therefore based on the object of providing an arrangement for making contact with resistance tracks which is simple in terms of production technology and permits convenient adaptation to the requirements of the respective application.
- FIG. 1 is a perspective view and shows an arrangement for contacting a potentiometer or resistance winding.
- Fig. 2 shows a cross section through the potentiometer.
- the arrangement for contacting resistor tracks 10, here a potentiometer or resistor resistor contains a base 12 made of electrically non-conductive, elastically flexible material.
- the pad 12 is a rubber disc.
- a corresponding plastic disk can of course also be used.
- An electrically conductive layer is applied to the base.
- this electrically conductive layer is formed by a conductive silver layer which is applied to the base 12 by means of screen printing.
- the electrically conductive layer contains arcuate sections 16 and 18 in the region of the ends of the potentiometer winding forming the resistance track 10 and adjoining, radially outwardly extending tongues 20, 22.
- the electrically conductive layer contains an arcuate section 24 in the central region of the potentiometer winding forming the resistance track 10. This arcuate area is relatively long and creates a short-circuit path.
- the electrically conductive layer a tongue 26 connected to the arcuate portion 24 and extending radially outward.
- the resistance track 10 is placed on the base 12, so that the arcuate sections 16, 18 and 24 rest on the underside of the resistance track 10.
- the resistance track 10 with the base 12 lies on a housing base plate 28.
- connection contacts 30 and 32 e.g. Faston plug
- a flat connection contact 34 extends radially outwards on the tongue 26.
- Means for pressing the resistance track 10 against the electrically conductive layer while prestressing the base 12 are formed by the housing base plate 28 and a cover part 36 which has an edge 38 projecting against the housing base plate 28.
- This cover part 36 lies on the resistance track 10 and is tightened against the housing base plate 28.
- the elastic base 12 is slightly deformed so that it adapts to the shape of the resistance track and, under pretension, produces good contact between the electrically conductive layer 16, 18, 24 applied to the base and the resistance track 10.
- the flat connection contacts 30, 32, 34 are pressed against the tongues 20, 22 and 26 of the electrically conductive layer by the front end 38- of the cover part 36, so that a reliable contact is ensured.
- a grinder 40 bears against the inside of the potentiometer winding forming the resistance track 10.
