VEHICULAR FEEDING DEVICE AND ELECTRICAL CONNECTION BOX

摘要

PROBLEM TO BE SOLVED: To prevent the connectors of a high-voltage system from being operated for connection or disconnection while conducting, by means of a simple arrangement and without reducing operational efficiency. SOLUTION: This vehicular feeding device which uses both a low-voltage battery and a high-voltage battery either has high-voltage system connectors 28 arranged in a centralized manner or can render the connectors 28 nonconducting by selectively shutting the high-voltage battery from a high-voltage load, or has means for preventing the connectors 28 from being operated for connection or disconnection while conducting. This vehicular electrical connection box is provided with a switch for breaking only the circuit of a high-voltage system.
