ON-VEHICULAR COMMUNICATION CONNECTION APPARATUS AND ON-VEHICULAR COMMUNICATION SYSTEM

摘要

PROBLEM TO BE SOLVED: To provide an on-vehicular communication connection apparatus and an on-vehicular communication system enhancing reliability against operation stopping at unexpected disconnection of power source.

SOLUTION: The on-vehicular communication connection apparatus is provided with a first diode D1 connected between an electricity receiving part 26 connected to a battery and a regulator 24 and feeding power from the electricity receiving part 26 to the regulator 24; a second diode D2 connected between the electricity receiving part 26 and a preliminary power source 22 such as an accumulator and feeding the power from the electricity receiving part 26 to the preliminary power source 22; and a third diode D3 connected between the preliminary power source 22 and the regulator 24 and feeding the power from the preliminary power source 22 to the regulator 24. A gate way is operated by the power fed from the regulator 24.
