Abstract
A power control unit is mounted on a hybrid vehicle, and controls the electric power used for driving the vehicle. The power control unit includes a PCU case having a top cover where an opening is formed, a terminal block placed in the PCU case, and arranged opposite to the opening, and a substrate placed in the PCU case, and on which an electronic component is mounted. The terminal block includes a wall. The wall is arranged between the substrate and opening, and extends towards the top cover at a circumference of the aperture of the opening. By such a configuration, there is provided a power control unit having an intrusion of a foreign object suppressed while accomplishing reduction in size and cost.

A power control unit mounted on a vehicle for controlling electric power used for driving the vehicle, comprising:
- a casing including a top where an opening is formed,
- a terminal block placed in said casing, and arranged opposite to said opening, and
- a substrate placed in said casing, and on which an electronic component is mounted,
- said terminal block having a first wall arranged between said substrate and said opening, and extending towards said top at a circumference of an aperture of said opening,
- said casing further including a rib-like section arranged between said substrate and said opening, and protruding from an inner edge of said top defining said opening towards inside said casing,
- said first wall being provided to block a line of sight from outside said casing towards said substrate, through said opening and over said rib-like section,
- said opening being formed to allow communication between the outer side of said casing and a space within said casing in which said substrate is placed,
- said first wall being provided not to be in contact with said casing.
