Abstract

An electric connection box according to one aspect of the present invention can include conductive members on a circuit board, a case accommodating the circuit board, a ventilation path formed in the case and through which air can flow in a vertical direction, a suction port formed in the case to be in communication with the ventilation path, an exhaust port formed in the case to be in communication with the ventilation path, the exhaust port positioned above the suction port, cooled portions positioned on the conductive members and positioned in the ventilation path so as to allow air to flow in the vertical direction between conductive members, and heat generating components connected to the cooled portions of the conductive members.

Description

Technical field [0001] The invention involves an Electrical Connection Box formed in the shell. Background technique [0002] In the past, as an electric connection box, the electric connection box was recorded in patent literature 1 (Japan special opening 2005-295724).The electrical connection box, the relay module equipped with a relay was contained on the circuit substrate.When power -on to the above relay, heat generates heat from the relay.After the heat is dispersed in the shell, it diverts from the wall of the shell to the outside. [0003] In recent years, the high density of the electric connector is required.Therefore, the number of relays that contain the shells increase, and the heat from the relay is increasing.Furthermore, the miniaturization of the electric connector is required, and the volume in the shell is decreasing.Therefore, the heat accumulation from relays in the shell may make the shell high temperature.If the shell becomes high temperature, the performan...
