Abstract
The utility model belongs to the field of electronic elements and particularly relates to a patch type potentiometer. The patch type potentiometer comprises an upper cover, a bottom shell, constant value pins and patch resistors, wherein the upper cover is matched and fixed with the bottom shell; the constant value pins are arranged around the bottom shell; the bottom shell is internally provided with an annular slide groove; the outer side of the slide groove is connected with the constant value pins; the inner part of the slide groove is connected with the patch resistors; the slide groove is internally provided with an electric brush; an electric brush circuit board is arranged in the middle of the bottom shell; a groove is formed in the outer surface of the upper cover; the position of the groove corresponds to the constant value pins; the groove is internally provided with a resistance value so as to realize random conversion of multiple resistance values; and meanwhile, the groove is arranged on the outer surface of the upper cover, the position of the groove corresponds to the constant value pins and the groove is internally provided with the resistance value, so that the direct reading of the resistance values of the constant value pins can be realized and an operator can conveniently weld according to process requirements.
Description
Technical field
The utility model belongs to the electronic devices and components fields, relates in particular to a kind of potentiometer.
Background technology
Potentiometer is to have the resistive element that three exits, resistance can be regulated by certain Changing Pattern.Potentiometer usually by resistive element and movably brush form.When brush moves along resistive element, namely obtain to become with displacement resistance value or the voltage of certain relation at output.
The structure function of potentiometer is single at present, the disclosed a kind of potentiometer structure of Chinese patent 201220023176.5 for example, it is characterized in that, the resistance pick-up piece that includes the contact of a potentiometer main body and a relative sliding, this potentiometer main body is provided with array resistors and pin position thereof in its insulating substrate, this array resistors is electrically connected with and branchedly is spaced plating of stretching out and conducts electricity wear-resisting pin, and array resistors is made as encapsulation state, make the resistance pick-up piece conduct electricity wear-resisting pin surface and carry out slide displacement location contact along branched the plating, to export corresponding resistance.
Although the potentiometer of this structure can reach the effect of conversion output resistance, the resistance of output need to be measured just and can know, if operating personnel's misoperation also can cause the production lot accident, thereby causes the cost waste.
Summary of the invention
in order to solve the problems of the technologies described above, the utility model provides a kind of chip potentiometer, comprise upper cover, drain pan, the definite value pin, Chip-R, described upper cover and drain pan are fixed, described definite value pin is arranged on the surrounding of described drain pan, it is characterized in that: be provided with the ring-type chute in described drain pan, the described chute outside and the definite value pin connection of being connected, described chute is inner and be connected the Chip-R connection, be provided with brush in described chute, the centre of described drain pan is provided with the brush wiring board, the outer surface of described upper cover is provided with groove, the position of described groove is corresponding with described definite value pin, be provided with resistance in described groove.
The beneficial effects of the utility model are: by be provided with chute, brush wiring board in drain pan, be provided with brush in chute, can realize any conversion of many resistances, outer surface at upper cover is provided with groove simultaneously, and the position of groove is corresponding with the definite value pin, is provided with the resistance number in groove, can realize intuitively reading of definite value pin resistance, handled easily personnel weld according to technological requirement, thereby avoid producing accident in batches, improves the quality of products.
