Antenna line protection device

摘要

An antenna line protection device includes a pair of coaxial connectors and a streamer discharge module. The pair of coaxial connectors are disposed on both side ends of the antenna line protection device. The streamer discharge module is coupled between the coaxial connectors so that, when a pulse signal is input via the coaxial connectors, the streamer discharge module induces an electric field and thus establishes a discharge current channel, thereby suppressing an excessive input pulse.

1. An antenna line protection device, comprising:
a pair of coaxial connectors disposed on both side ends of the antenna line protection device; and a streamer discharge module coupled between the coaxial connectors so that, when a pulse signal is input via the coaxial connectors, the streamer discharge module induces an electric field and thus establishes a discharge current channel, thereby suppressing an excessive input pulse, wherein each of the coaxial connectors comprises: a body part provided with a through hole extending from a first end of the body part through the body part to a second end thereof, and a flange extending along an outer periphery of the second end of the body part; an input/output interface part provided at the first end of the body part, and provided with a connector protruding in a direction corresponding to that of the body part; a dielectric part formed to protrude from the input/output interface part in a direction corresponding to that of the connector and to be inserted into a first end of the through hole; and a first center electrode disposed inside the through hole, formed to extend in a longitudinal direction of the through hole, and configured such that a first end of the first center electrode is connected to the dielectric part and a fastening hole is formed at a second end of the first center electrode to allow a fastening member to be fastened into the fastening hole, wherein the through hole is formed in a tapered shape such that a diameter thereof remains uniform through a portion near the first end of the body part and then increases in a direction toward the second end of the body part, and wherein the first center electrode is formed in a tapered shape such that a diameter thereof remains uniform and then increases in a direction toward a second end thereof.
