Abstract

The invention discloses an overcurrent and overtemperature protection element, comprising: a first conductive member which comprises a power input part and a first insulation part for limiting the input of the current only through the power input part; a second conductive member which comprises at least two power output parts and a second insulation part for limiting the output of the current only through the power output parts, wherein the power output parts are insulated from each other by using the second insulation part; a resistive element stacked between the first conductive member and the second conductive member; a power input part electrode tip electrically connected with the power input part, and a power output part electrode tip electrically connected with the power output part. According to the invention, multiport type overcurrent and overtemperature protection element disclosed herein can simultaneously provide overcurrent and overtemperature protection for two or more loops.

Description

technical field [0001] The invention relates to a passive element, especially to an overcurrent and overtemperature protection element. Background technique [0002] Thermistors are used to protect circuits from being damaged by overheating or excessive current flow. A thermistor usually consists of two electrodes and a resistive material between the two electrodes. This resistance material has a low resistance value at room temperature, and when the temperature rises to a critical temperature or an excessive current is generated on the circuit, its resistance value can immediately jump by more than thousands of times, thereby inhibiting the passage of excessive current to reach the circuit purpose of protection. [0003] When the temperature drops back to room temperature or there is no overcurrent on the circuit, the thermistor can return to a low resistance state, allowing the circuit to operate normally again. This reusable advantage makes thermistors replace fuses an...
