Problems solved by technology

[0005] In order to overcome the poor safety of traditional wire-wound resistors, which make it unable to meet the protection against lightning surge and over-low current at the same time, it is easy to cause fire; secondly, when the traditional wire-wound resistors are used for capping operation, they need The user performs a separate capping operation on a single wirewound resistor, so that the user cannot complete the capping operation of multiple wirewound resistors at the same time, which reduces the work efficiency of the wirewound resistor capping process; at the same time, the traditional wirewound resistor After the resistor is capped, it is impossible to uniformly store the wire-wound resistors after the capping process, which increases the operation steps of the wire-wound resistor receiving operation, which brings certain adverse effects to the user. Provide a full short-circuit lightning surge anti-surge wirewound resistor

Abstract

The invention discloses a full-short-circuit anti-lightning surge wire-wound resistor which comprises a first pin, a metal wire, a second pin, a sealing column, a ceramic rod and a sealing gland, the first pin is fixedly installed in the middle of the lower end of the sealing gland, the ceramic rod is fixedly installed in the middle of the upper end of the sealing gland, the metal wire is wound on the outer surface of the side edge of the ceramic rod, the sealing gland is fixedly installed on the outer surface of the lower end of the sealing column, and the second pin is fixedly installed on the lower portion of the outer surface of one side of the sealing column. According to the full-short-circuit anti-lightning surge wire-wound resistor disclosed by the invention, a resistor generates an open circuit phenomenon under the condition that the temperature of the resistor reaches the temperature which is about to endanger the safety of a product, so that the safety of the product is improved, a fire hazard phenomenon is avoided, the resistor can simultaneously meet the requirements of lightning surge impact resistance and undercurrent protection, and the safety of the resistor is improved.

Description

technical field [0001] The invention belongs to the field of resistors, and more specifically relates to a full-short-circuit anti-lightning surge wire-wound resistor. Background technique [0002] With the rise of mobile phones, especially smart phones, the batteries of mobile phones are getting bigger and bigger, and the trend of miniaturization and high power of chargers used for charging them is gradually strengthened. During the charging process of mobile phones, abnormal states such as micro-short circuits appear inside the charger, causing The safety accidents of charger fires continue to occur, and the reason for the fire is that the resistors used in the charger cannot meet the anti-lightning surge impact and over-low current protection at the same time. Resistors previously used in electronic product chargers are required to be able to withstand lightning surges, and at the same time, under high current conditions, the resistors will be disconnected within a specif...
