[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-encapsulated resistor, specifically relating to the field of resistance, including a resistance mechanism for adjusting the size of the current blocking effect in a circuit. Both ends of the resistance mechanism are electrically connected with conductor connections for auxiliary connection of components at various levels. Mechanism, the interior of the conductor connection mechanism is equipped with a reset mechanism as a transmission power source. When the connecting section of the torsion spring is disconnected from the fuse block, the reset-type ruler spring section drives the center positioning sleeve to rotate, and uses the meshing of the corresponding external thread groove and the guide piece internal thread groove to push the outer ring sleeve to guide The end of the body connection mechanism moves, thereby pushing the conductor-type cantilever and the elastic arc conductor to bind the rod-shaped wires outside the conductor connection mechanism, which relatively improves the problem that small circuit board components are difficult to weld evenly for electrical connection.

Description

technical field [0001] The present invention relates to the technical field of resistors, and more particularly, to a semi-precision plastic-encapsulated resistor. Background technique [0002] Resistors are generally called resistors directly in daily life, and the resistor is a current-limiting element. After connecting the resistor in the circuit, the resistance value of the resistor is fixed. Generally, it is two pins, which can limit the connection through it. The current size of the branch, the resistance value cannot be changed is called a fixed resistor, the resistance value is variable is called a potentiometer or a variable resistor, the ideal resistor is linear, that is, the instantaneous current passing through the resistor and the external 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 pressed tightly, and the contact position determines the...
