Problems solved by technology

However, according to this method, since the air is only in contact with the surface of the bus bar, heat cannot be effectively transferred from the bus bar to the air, and it is difficult to sufficiently cool the bus bar

Embodiment Construction

[0032] Embodiments of the present invention will be specifically described below with reference to the drawings.

[0033] A first embodiment of the present invention will be described with reference to FIGS. 1 to 7 . The electrical connection box according to this embodiment is installed between a battery (not shown) and on-vehicle electrical components (not shown) such as lamps and power windows, and controls the power supply and shutdown of these on-vehicle electrical components. This electrical connection box is installed in the interior of a car (not shown) in a vertical state as shown in FIG. 6 and used. In this electrical connection box, a circuit board 11 is accommodated in a flat case 10 .

[0034] (circuit board)

[0035] The circuit board 11 is substantially rectangular, and conductive paths (not shown) are formed on both sides thereof by printed wiring technology. On the right side of the circuit board 11 in FIG. 7 (hereinafter referred to as the mounting surface...

Abstract

An electrical connection box, which includes: a circuit substrate; a plurality of conductive components arranged on the circuit substrate spaced apart from each other and extending in a direction away from the circuit substrate; a housing that connects the circuit The substrate is accommodated inside; the gas passage is formed in the casing, and allows air to circulate in the up and down direction; the air inlet is arranged on the casing and connected with the gas passage; the exhaust port is arranged on the The casing is connected with the gas passage, and is arranged above the air inlet; the part to be cooled is arranged on the conductive component, and is located in the gas passage so that air flows in the conductive part. The parts communicate up and down; and the heating part is connected with the cooled part of the conductive part.

Description

technical field [0001] The present invention relates to an electrical connection box formed by accommodating a circuit board in a casing. Background technique [0002] Conventionally, the electric connection box described in patent document 1 (Japanese Unexamined Patent Publication No. 2005-295724) is known as an electric connection box. In this electrical connection box, a relay module on which a relay is mounted is accommodated on a circuit board. When power is supplied to the above-mentioned relay, heat is generated from the relay. After the heat is dissipated into the housing, it is dissipated from the wall of the housing to the outside. [0003] In recent years, densification of electrical connection boxes has been demanded. Therefore, the number of relays housed in the case increases, and the heat generated from the relays tends to increase as a whole. Furthermore, miniaturization of the electrical connection box is also required, and the volume in the housing tend...
