Electronic element with flame-retardant function

Abstract

The invention relates to the technical field of electronic components, and discloses an electronic component with a flame-retardant function, which comprises a shell, and the surface of the shell is fixedly connected with a flame-retardant three-proofing paint. According to the electronic component with the flame-retardant function, a heat dissipation hole is formed in the right side of the shell,a heat dissipation outer guide pipe extending into the shell is inserted into the heat dissipation hole; and the heat dissipation outer guide pipe is made of a copper-silver alloy. The copper-silveralloy has good heat gathering performance and heat dissipation performance; then, a heat gathering rod is fixedly arranged on the surface of the heat dissipation outer guide pipe in the shell; the contact area with heat is increased, more heat can be gathered, the heat dissipation rod is fixedly installed on the surface of the heat dissipation outer guide pipe outside the shell and used for increasing the contact area with outside air and further enhancing the heat dissipation performance of the heat dissipation outer guide pipe, and finally a filter screen is fixedly installed in the heat dissipation inner insertion pipe and can guarantee that outside dust cannot enter the shell in the heat dissipation process, so that the service life is shortened.

Description

technical field [0001] The invention relates to the technical field of electronic components, in particular to an electronic component with a flame-retardant function. Background technique [0002] Some existing electronic components, such as varistors, thermistors, capacitors used in power circuits, commonly known as medium and high-voltage capacitors, insurance tubes, etc., when the current or voltage in the circuit exceeds its withstand capacity, a shock will occur. Short circuit phenomenon, in the actual circuit, the instantaneous energy is very large when the short circuit occurs, and local high temperature will be generated at the damaged part of the breakdown, which may cause the protective layer sealed outside the above-mentioned electronic components to burst or even ignite. In severe cases, it may cause electrical equipment to catch fire . [0003] Chinese patent CN100365743C proposes an electronic component with flame retardant function. This patent provides an e...

Problems solved by technology

[0005] Aiming at the deficiencies of the prior art, the present invention provides an electronic component with a flame-retardant function, which has the advantages of fast heat dissipation and good flame-retardant effect, and solves the problem that the heat generated by the electronic component cannot be dissipated well and quickly. If it goes out, it is easy to burst the electronic component body after the accumulated heat exceeds a certain load, and there will be a breakdown and short circuit phenomenon, which will cause the electronic components around the body of the invention to spontaneously ignite, and in severe cases, the entire device will catch fire.
