I / O CONNECTOR FOR SATELLITE RADIO}

The present invention relates to an I / O connector for satellite radio in satellite broadcasting, and more particularly, to improve product compatibility and to be easily coupled and released, and to have a relatively low failure rate due to careless handling of a user. The present invention relates to an I / O connector for a satellite radio composed of male and female connectors of SMT (Surface Mounted Technology) type, which has almost no wear and can exhibit its function stably without contact failure.

In general, satellite broadcasting requires satellite antennas for receiving radio waves transmitted from satellites, and receivers, which are receivers for detecting radio waves received by satellite antennas and converting them into desired video or audio signals. The signal transmission between the same satellite antenna and the receiver is divided into RF (Radio Frequency) receivers for determining the desired bandwidth and signal terminals for receiving actual video or audio signals. The RF signals are mainly received through coaxial cable and The voice signal is received through the signal terminal of the connector.

However, in the conventional satellite broadcasting device, the structure of the satellite antenna and the receiver is complicated, and the work is cumbersome and incompatible when detached. In particular, in the case of satellite radio, which is a satellite broadcasting device, detachment occurs frequently between the satellite antenna and the receiver. Therefore, the signal terminal of the connector connecting the satellite antenna and the receiver and the coaxial cable and coaxial plug must be connected or disconnected each time the detachment is performed. There is a lot of trouble, and the incidence of failure increases due to careless handling of the user. In addition, when the user wants to replace the product, there is a problem that it is not easy to purchase the desired product because of the incompatibility as described above.
