Problems solved by technology

[0003] When electrical equipment is energized and used, the current flowing through the resistor will generate high temperature and high heat. The phenomenon of overheating, explosion and burning, the shock wave and the fragments of the resistor will damage the electronic components near the resistor, cause a short circuit on the circuit board, make the electrical equipment unable to operate normally, cause serious damage, and even cause a fire in severe cases
In order to avoid the occurrence of the above-mentioned accidents, people are committed to researching safer resistors, and people are researching on resistor materials and protective equipment. However, due to the limitation of the preparation cost of the existing protection technology, the explosion-proof effect of explosion-proof resistors is general.

Abstract

The invention discloses a high performance resistor. The resistor comprises a resistor body, a wire and an outer housing, wherein the resistor body is arranged in the outer housing, the wire is connected with the resistor body and penetrates out from both ends of the outer housing, the outer housing is of an enclosed cylindrical structure, end covers and a cylinder body of the outer housing are bonded by using a sealant, and gel is filled between the resistor body and the outer housing. According to the high performance resistor disclosed by the invention, the outer housing is additionally arranged at the exterior of the resistor body, the conductive cold gel is filled between the resistor body and the outer housing and can effectively reduce the phenomenon of overheating of the resistor, and the outer housing has high strength and can prevent damage of shock waves and debris generated during explosion of the resistor caused by overheating to surrounding components and equipment; meanwhile, preparation cost for the outer housing is moderate, a preparation process for the outer housing is simple and convenient, the gel is easy to fill and has stable performance, so usage performance and safety of the resistor are greatly enhanced.

Description

technical field [0001] The invention relates to a resistor, in particular to a safe and efficient new resistor, which belongs to the technical field of electronic components. Background technique [0002] Resistors are one of the most widely used components in electrical equipment circuits. In physics, resistance is used to represent the resistance of a conductor to current. The greater the resistance of a conductor, the greater the resistance of a conductor to current. The resistance value of the resistor is generally related to temperature, conductor length, cross-sectional area, and material. There are many kinds of resistors and various functions. According to the resistance value, resistors can be divided into: fixed resistors, adjustable resistors, special resistors (sensitive resistors); according to the manufacturing materials, resistors can be divided into: carbon film resistors, metal film resistors, Wirewound resistors, non-inductive resistors, thin film resisto...
