Abstract
The invention relates to power plugs, particularly to an electric spark eliminating plug and a coating production process. The electric spark eliminating plug comprises plug contact pieces and is characterized in that the head portions of at least one group of the plug contact pieces are coated with resistive layers made of resistive coatings, wherein the resistive coatings are composed of conductive fillings, substrate resin, additives and solvent. The electric spark eliminating plug has the advantages of being capable of eliminating electric sparks generated when plugged in and pulled out, avoiding corrosion or burnout of the contact pieces and accordingly being applicable to anti-explosion places. The coating process of the resistive coatings is low in cost and high in production efficiency.
