Embodiment Construction

[0010] The following descriptions are only preferred embodiments of the present invention, and therefore do not limit the protection scope of the present invention.

[0011] Examples, see figure 1 Shown: a stepless variable value resistor, including a resistor body 10 and two pins 12 . Wherein, the body 10 may be an alloy body material. The body 10 is in the shape of a cuboid, and at the same time, the two pins 12 are in the shape of a flat plate with the same width as the body 10 , and are respectively attached to the upper and lower sides of the body 10 . In this way, when the resistance value of the resistor needs to be changed, only the lateral side 11 of the main body 10 needs to be ground, so that the length of the main body 10 decreases linearly, so that the resistance value of the main body 10 decreases linearly.

[0012] Further, in order to facilitate soldering of the pins 12 to a circuit board or the like, the widths of the ends of the two pins 12 away from the bo...

Abstract

The invention discloses an electrodeless value varying resistor which comprises a resistor main body in shape of a cuboid and two pins in shape of flat plates, the resistor main body is as wide as the two pins, the two pins are respectively adhered on the upper side surface and the lower side surface of the main body. Preferentially, one ends of two pins far from the main body are narrower than the main body. The electrodeless value varying resistor has the advantages that the electrodeless value varying resistor is relatively small in size, and can perform electrodeless value variation.

Description

technical field [0001] The invention relates to the technical field of electronic components, in particular to an infinitely variable value resistor. Background technique [0002] Resistors are the most commonly used electronic components. Among them, there are many kinds of variable-value resistors that can change the resistance value of the resistor, such as a sliding wire resistor or a combination of several resistors in different connection modes to form a stepwise change in resistance value. Its disadvantages are: the volume is large or the stepless change in which the resistance value of the resistance changes linearly changes cannot be realized. Therefore it is necessary to improve it. Contents of the invention [0003] In view of the shortcomings of the above-mentioned prior art, the object of the present invention is to provide a non-polar variable value resistor, which has the characteristics of small volume and non-polar variable value. [0004] In order to a...
