Abstract: Provided is an electrical connection box that achieves downsizing by means of efficient arrangement of electronic components and terminals on a board. An electrical connection box (1) includes a board (21), a terminal holder (22), flat-plate terminals (23), and electronic components (24). The terminal holder (22) is mounted to the board (21). The flat-plate terminal (23) includes a first portion (41), a second portion (42), and a third portion (43). The first portion (41) is connected to the board (21), and extends substantially perpendicularly from the board (21). The second portion (42) is connected to the first portion (41), and extends substantially in parallel with the board (21). The third portion (43) is connected to the second portion (42), is connectable to a connector, and extends substantially perpendicularly to the board (21). The electronic component (24) is arranged between the second portion (42) of the flat-plate terminal (23) and the board (21).

Abstract: Provided is an electrical junction box that enables appropriate protection of a bus bar and also enables downsizing. The electrical junction box includes a terminal reception block (11) that accommodates a connection terminal, and a casing (12) that accommodates the terminal reception block (11). The terminal reception block (11) is configured such that a bus bar (19) is inserted into the terminal reception block (11) and an end portion of the bus bar (19) at the side opposite to the direction of insertion protrudes from the terminal reception block (11). The casing (12) includes a protector (20) that is configured to cover the end portion of the bus bar (19) protruding from the terminal reception block (11). Making the terminal reception block (11) accommodated in the casing (12) causes the end portion of the bus bar (19) to be covered with the protector (20).

Abstract: Drain structure of an electric connection box is provided that is capable of preventing penetration of water with simplicity. According to the drain structure of the electric connection box, since a pair of engaging leg portions of a waterproof lid is engaged in a peripheral part of a communication hole of the drain portion and a lid portion covers the upper part of the water discharging hole, the water that penetrates through to the inside of the electric connection box through the communication hole and water discharging hole of the drain portion can be dammed in use of lid portion of the waterproof lid and can be prevented from gushing into the electric connection box. As a result, since it is possible to prevent the terminal portion of a wire such as a wire harness or the like, which is arranged to run from moistening with the water, penetration of water can be surely prevented.

Abstract: The metal-core-board reinforcing structure has a metal core board having a metal core and a resin plate having substantially the same extent as that of the metal core board and being fixedly attached to the metal core board substantially parallel to one side of the metal core board and spaced apart therefrom by a predetermined distance.

Abstract: [Problems to be Solved]The present invention provides a metal-core-board reinforcing structure which can simultaneously satisfy various requirements such as miniaturization, weight reduction, space-saving, heat radiation and provision of mechanically reinforced metal core board. [Means to Solve the Problems] The metal-core-board reinforcing structure according to the present invention has a metal core board 1 having a metal core and a resin plate 2 having substantially the same extent as that of the metal core board 1 and being fixedly attached to the metal core board 1 substantially parallel to one side of the metal core board 1 and spaced apart therefrom by a predetermined distance.

Abstract: An electric connection box includes upper and lower cases which accommodate therein bus bars, an insulator for the bus bars, fuses, and first relays. A relay module mounted with second relays is accommodated in the upper and lower cases. The electric connection box includes the relay module, but is compact in size, light in weight, low-priced, and low in heat generation due to contact resistance.
