Problems solved by technology

[0003] A resistor is a component used in a circuit, and at the same time protects the circuit to prevent other components from being burned out. In other words, it is the resistance of the conductor to the current in the circuit. It is aimed at the precision and semi-precision In the electrical connection of resistance resistors, it is usually connected on a small circuit board. Due to the small size of the components at all levels, it is impossible to make the welding surface more uniform during the wire welding process, and at the same time, it is prone to the problem of broken welding. Therefore, it is necessary to Design a small precision and semi-precision resistor that facilitates the electrical connection of all levels of components at all angles for practical development and use

Abstract

The invention discloses a semi-precision plastic package resistor, and particularly relates to the field of resistors, the semi-precision plastic package resistor comprises a resistor mechanism used for adjusting the current blocking effect in a circuit, and the two ends of the resistor mechanism are electrically connected with conductor connecting mechanisms used for assisting in connecting all levels of elements. A reset mechanism serving as a transmission power source is installed in the conductor connecting mechanism. When a torsion spring connection section is disconnected from a fusing block, the reset type ruler spring section drives the central positioning sleeve to rotate, and the outer ring sleeve is pushed to move towards the end part of the conductor connection mechanism by utilizing the meshing of a corresponding external thread groove and a guide sheet type internal thread tooth groove. Therefore, a conductor type cantilever and an elastic arc sheet conductor are pushed to bind a rod-shaped wire outside the conductor connecting mechanism, and the problem that small circuit board elements are difficult to weld uniformly for electrical connection is relatively solved.

Description

technical field [0001] The invention relates to the technical field of resistors, and more specifically, the invention relates to a semi-precision plastic-encapsulated resistor. Background technique [0002] Resistors are generally directly called resistors in daily life, and resistors are a current-limiting element. After the resistor is connected to the circuit, the resistance value of the resistor is fixed. Generally, there are two pins, which can limit the The current size of the branch, whose resistance value cannot be changed is called a fixed resistor, and the one whose resistance value is variable is called a potentiometer or a variable resistor. The ideal resistor is linear, that is, the instantaneous current through the resistor and the applied instantaneous current The voltage is proportional to the variable resistor used for voltage division. On the exposed resistor body, one or two movable metal contacts are tightly pressed. The position of the contact determine...
