Quando ocorre falha de contato em um conector em uma linha coaxial de transmissão de sinal HF, um campo eletromagnético é irradiado ao redor da linha. Medimos o campo eletromagnético e examinamos as características dessa radiação. Os resultados mostram que a radiação está relacionada com a resistência de contato e com a simetria da distribuição dos pontos de contato no conector. Quando a resistência de contato é baixa, a radiação é observada em frequências ressonantes relacionadas ao comprimento da linha de transmissão. Se um conector tiver pontos de contato axialmente assimétricos, sua radiação será maior do que quando os pontos de contato forem simétricos. Mostramos que se os pontos de contato em um conector forem axialmente simétricos com resistência inferior a 0.25 Ω, a interferência eletromagnética causada pela falha no contato do conector é tão baixa quanto o ruído de fundo.

Abstract: When contact failure occurs in a connector in a coaxial HF signal transmission line, an electromagnetic field is radiated around the line. We have measured the electromagnetic field and examined the characteristics of such radiation. The results show that the radiation is related to the contact resistance and the symmetry of the distribution of contact points at the connector. When contact resistance is low, radiation is observed at resonant frequencies related to the length of the transmission line. If a connector has axially asymmetric contact points, its radiation is higher than that when the contact points are symmetric. We show that if contact points in a connector are axially symmetrical with resistance lower than 0.25 Ω, the electromagnetic interference caused by the connector contact failure is as low as the background noise.

AB - When contact failure occurs in a connector in a coaxial HF signal transmission line, an electromagnetic field is radiated around the line. We have measured the electromagnetic field and examined the characteristics of such radiation. The results show that the radiation is related to the contact resistance and the symmetry of the distribution of contact points at the connector. When contact resistance is low, radiation is observed at resonant frequencies related to the length of the transmission line. If a connector has axially asymmetric contact points, its radiation is higher than that when the contact points are symmetric. We show that if contact points in a connector are axially symmetrical with resistance lower than 0.25 Ω, the electromagnetic interference caused by the connector contact failure is as low as the background noise.
