Abstract
In a heat radiator plate, a mounting bracket extending from a peripheral edge portion of the heat radiator plate, an auxiliary heat radiator plate portion extending along the mounting bracket and positioned between the mounting bracket 39 and a body through a gap and a radiant heat radiator portion formed on a top end of the auxiliary heat radiator plate portion and opposing to the body through the gap are provided. Heat generated by a circuit construction body is conducted from the heat radiator plate, the auxiliary heat radiator plate portion and the radiant heat radiator portion to the gap and radiated to the body through the gap. The heat radiation characteristics of the connector box are improved.
Claims7
An electric connector box comprising:
- a casing including a frame and a heat radiator plate mounted on a mounting body, the heat radiator plate facing a surface of a circuit substrate that opposes a component surface having a component mounted thereon;
- a mounting bracket mounting the electric connector box on the mounting body, the mounting bracket extending stepwise from a peripheral edge portion of the heat radiator plate, the mounting bracket having a bearing surface on a top end portion, the bearing surface being closely fixed to the mounting body by a tightening member;
- and
- an auxiliary heat radiator plate portion extending from the peripheral edge portion of the heat radiator plate and separated from the mounting body by a first gap, and the auxiliary heat radiator plate portion being spaced apart from the mounting body.
