Chip type thin film fixed resistor

Abstract

The invention relates to the technical field of resistors, and concretely relates to a chip type thin film fixed resistor. The fixed resistor comprises a fixed plate, a protection mechanism is arranged on the upper surface of the fixed plate, a pressing mechanism arranged on the upper surface of the fixed plate, and a clamping mechanism is arranged in the fixed plate. The resistor is supported through an arranged bottom frame, then the bottom frame provided with the resistor is inserted into a sliding groove, the resistor enters the protection groove, the resistor is protected through the protection frame, a pressing block is pushed through a pressed block and a triangular block which are fixed to the bottom of the bottom frame, then the pressing block moves towards the interior of the pressing groove, the pressing block is pushed upwards through a spring, the pressing block pushes the pressed block upwards, the pressed block pushes the bottom frame upwards, the bottom frame is fixed in the sliding groove through extrusion, the resistor is fixed in the protection frame, the resistor is protected through the protection frame, the resistor is prevented from being bent after being pressed, and the resistor is prevented from being damaged.

Description

technical field [0001] The invention relates to the technical field of resistors, in particular to a chip type thin film fixed resistor. Background technique [0002] Resistors are generally directly referred to as resistors in daily life. They 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 branch circuit connected to it. The size of the current, the resistance cannot be changed is called a fixed resistor, and the variable resistance is called a potentiometer or variable resistor. [0003] The existing resistor is fixed on the circuit board through two pins, so that the main components of the resistor are exposed. When the circuit board is hit, the resistor will be the first to be hit. When the resistor is hit When impacted, the fragile pins on the resistor will be torn off first, and the resistor cannot be effectively fixed on the circuit board...

AI Technical Summary

Problems solved by technology

[0004] The resistor in the prior art is fixed on the circuit board through two pins, so that the main components of the resistor are exposed. When the circuit board is hit, the resistor will be the first to be hit. When the resistor is hit, the fragile pins on the resistor will be torn off first, and the resistor cannot be effectively fixed on the circuit board, and the surface of the film resistor is relatively fragile, which will cause the resistor to be damaged when it is pressed. Bending occurs, and when the bending angle is large, it may cause damage to the resistor, which in turn may cause greater damage to the circuit. The present invention provides a chip type film fixed resistor
