Abstract: Provided is an electrical connection box with a simple configuration that can prevent liquid from running into a housing. An electrical connection box for a vehicle provided with a case member for installing a first fuse includes a removal port formed at a front surface of the case member, the removal port enabling the first fuse to be installed and removed; and a groove formed around the removal port, the groove guiding liquid running down the front surface away from the removal port.

Abstract: Provided is an electrical junction box including a substrate on which fixed fuses and replaceable fuses are mounted. The substrate includes a first part to which the fixed fuses are soldered, and a second part that excludes the first part. The first part and the second part are separable from each other.

Abstract: A connector module that is provided with an input port and an output port that are configured to be connected to an external member, and is to be mounted on a substrate, the connector module including: a bus bar that is separated from the substrate and connects a terminal of the input port and a terminal of the output port to each other; and an insulating member that is interposed between the bus bar and the substrate.

Abstract: An electrical connection box includes a substrate on which a fuse element including terminals is mounted, and a case member in which the substrate is housed. Through holes pass through the substrate in the thickness direction, the terminals of the fuse element are inserted into the through holes on one surface side of the substrate and protrude from the other surface side, and the protruding portions of the terminals are in contact with the case member.
