Problems solved by technology

[0003] Since the high stability resistor is connected to the circuit wire through the pin, if the circuit wire is multi-strand thin copper wire, it is easy to generate high temperature after the circuit is short-circuited and the thin copper wire will melt and adhere to the inner side of the pin, so When the high stability resistor is used again, the resistance generated by itself will increase due to the copper melting layer attached to the pin, which will cause the resistance value of the high stability resistor to deviate

Abstract

The invention discloses a resistor with high stability. Its structure includes a resistor, a connecting block, and a fixing nail. The fixing nail is threadedly connected to the upper end of the resistor. The outer frame is stretched back and forth, so that the impact rod can follow the inertial force to impact the inner wall of the plate body, so that the plate body can transmit the vibration to the wiring ring, so that the inner extension plate can be placed between the transition block and the pull-back bar. Cooperate with the back and forth expansion and contraction along the external ring, so that the inner extension plate will shake off the copper melting layer on the inner side after repeated expansion and contraction, and the thrust generated between the two swing plates by the reverse air flow can make the swing plate move along The fixed rod swings upwards, so that the swing plate can block the copper scraps entering from the outside, and then the blocked copper scraps can be collected through the collection groove.

Description

technical field [0001] The invention relates to the field of resistors, in particular to a resistor with high stability. Background technique [0002] The high stability resistor is mainly used to limit the current. It is connected to one end of the circuit through one end of the pin, and then connected to the other end of the circuit through the other end of the pin, so that it can control the current passing through it. For current limiting, based on the above description, the inventors found that an existing resistor with high stability mainly has the following deficiencies, for example: [0003] Since the high stability resistor is connected to the circuit wire through the pin, if the circuit wire is multi-strand thin copper wire, it is easy to generate high temperature after the circuit is short-circuited and the thin copper wire will melt and adhere to the inner side of the pin, so When the high stability resistor is used again, the resistance generated by itself will...
