Power supply unit and connector connection failure detection method
First Claim
1. A power supply unit adapted to supply power from a power supply section to a load via a plurality of power supply lines connected by an on/off switch and connectors, said power supply unit comprising:
- load open detection means for detecting an open state of said connectors between said on/off switch and said load;
monitor means for monitoring the number of times said open state has been entered per unit time based on a detection result of said load open detection means; and
control means for controlling said on/off switch off when the number of times said open state has been entered per unit time is greater than a predetermined number of times.

Abstract
A power supply unit adapted to supply power from a power supply section to a load via a plurality of power supply lines connected by an on/off switch and connectors. The power supply unit includes a load open detection section for detecting an open state between the on/off switch and the load, a monitor section for monitoring the number of times the open state has been entered per unit time based on the detection result of the load open detection section, and a control section for controlling the on/off switch off when the number of times the open state has been entered per unit time is greater than a predetermined number of times.

5. A method for detecting a connection failure of connectors when power from a power supply unit is supplied to a load via a plurality of power supply lines connected by an on/off switch and said connectors, said method comprising the steps of:
-
detecting the number of times an open state has been entered by said connectors between said on/off switch and said load per unit of time; and determining that a connection failure occurs in said connectors when the number of times the open state has been entered is greater than a predetermined number of times. - View Dependent Claims (6, 7)
