"Effects of the Invention" As described above, the present invention provides a cradle having a plurality of rows of connector seats in which high-frequency coaxial connector seats are arranged at predetermined intervals, and A plurality of mounting units having the same shape are provided with a plurality of mounting units having the same shape, each of which is arranged so as to fit into the plurality of mounting units. In the electrical connection structure of CATV signal transmission equipment, which is electrically connected by inserting and mating into the cradle in the same direction, the connector seat row of the cradle is divided into a female connector seat and a male connector seat. The arrangement order is arranged differently for each row of connector seats, and each mounting unit has a male connector seat and a female connector seat that fit with the connector seats for each row of connector seats on the pedestal. This is an electrical connection structure for CATV signal transmission equipment that is designed to prevent the installation unit from being installed incorrectly, so the installation unit can be reliably installed at the specified location, and it cannot be installed at other than the specified location. There is no chance of wearing it incorrectly.

According to the present invention, when voltage is superimposed on the male connector seat, safety is improved because different mounting units are not installed. Further, unnecessary circuits such as a current cut-off circuit for preventing damage when incorrectly attached to the mounting unit can be omitted. Furthermore, there is no need for a separate male connector for supplying power to each mounting unit, allowing for a compact design.
