Technical field
The utility model relates to a kind of conductive rubber specific insulation measurement jig.
Background technology
Conductive rubber is evenly distributed in silicon rubber by the conductive particle such as silver-plated, silver-colored to glass silvering, aluminium, by pressure, conductive particle contacted, reach good electric conductivity.Military and commercially have application.Its Main Function is sealing and electromagnetic screen.Wherein the principle of electromagnetic shield-ing of conductive rubber is as follows: 1. the conductive particle of filling in conductive rubber is when filling certain volume number, contact with each other, form electronics continuous state, when external electromagnetic field is outside to conductive rubber, strong electromagnetic wave is got on conductive particle free electron, free electron free movement, and free electron forms the electromagnetic field contrary with external electromagnetic field in motion process, interior external electromagnetic field is cancelled out each other, and reaches the effect weakening electromagnetic interference wave; 2. another one principle is Conversion of Energy, law of conservation of energy, and electromagnetic wave is got on free electron, in free electron motion process, because conductive particle has certain resistance, produce heat, i.e. electromagnetic interference wave---free electron motion energy---heat energy, to weaken electromagnetic interference wave.And the specific insulation of conductive rubber can affect its electromagnet shield effect, usually test volume resistivity need be carried out in third-party testing mechanism or construction shielding properties test cabinet, but its apparatus expensive, testing procedure is complicated, and testing expense is higher.
