The connector may include a latch and a tab. The latch may be disposed on the cover and the tab may be disposed on the housing member. The tab may include a first surface, a second surface, and a third surface that may extend obliquely or perpendicularly relative to each other. The second surface may extend from and connect the first surface to the third surface. The latch may be biased toward contact with the tab. The second surface may be configured to facilitate a sliding movement of the latch toward an engaged position.

The present disclosure relates to a power converter for use in a host vehicle. The power converter comprises a DC link, a DC link capacitor, and a pre-charge circuit configured to charge the DC link capacitor. The pre-charge circuit comprises a boost converter comprising a switch and inductor coupling terminals configured to couple to an inductive component external to the power converter.

A novel electrical box to house one or more ISO micro relays, is adapted to support IP67 and IP69K Ingress Protection ratings. The housing of the electrical box is molded with blade sockets that correspond to blade positions of the ISO micro relay. The housing is also molded with terminal seats and cylindrical openings which vary, depending on the blade socket, enabling terminals of different sizes, orientations, and positions relative to the respective blades, to be easily inserted into the back of the housing. The resulting position of the terminals ensures that electrical connections to the ISO micro relay are made and ingress protection of components inside the electrical box is ensured.

Provided are an electrical junction box for which the time required for production is short, and a method for manufacturing the electrical junction box. An electrical junction box houses an electric device. A plurality of external devices are connected to each other via the electric device housed in the electrical junction box. The electrical junction box includes a housing box and a connector. The housing box is provided with an insertion port 40 into which the connector is inserted, and an opposite opening that is opposite to the insertion port. The insertion port and the opposite opening have the same axial direction. Inside the housing box, a component can be attached to the connector.

A fuse box for a battery of a vehicle includes: a lower housing having a space in which a fuse is housed and a bus bar for electrically connecting the battery and the fuse is seated; a plate-shaped upper housing having a through hole formed at a central portion thereof and a first extending portion extending upward along a circumference of the through hole, where the upper housing is assembled on an upper side of the lower housing; and a fuse cover that is coupled to an upper side of the upper housing to cover the fuse exposed through the through hole of the upper housing.

An objective of the present invention is to improve the discharge capacity for liquid collected within a casing while suppressing liquid entering a discharge opening from the outside. A liquid discharge structure includes a plate-shaped bottom wall with a discharge opening for liquid, the liquid being collected inside a casing 1 which is configured to be installed in a vehicle, a blocking wall outside the bottom wall, wherein the blocking wall is overlapped with the discharge opening in a plan view on the bottom wall and opposed to the bottom wall with a gap between the blocking wall and the bottom wall, and a fixing mechanism which is disposed not to be overlapped with the discharge opening in the plan view, wherein the fixing mechanism is configured to fix the blocking wall relative to the bottom wall in an attachable and detachable manner.

A communication system includes a host control device and a vicarious inputting and outputting unit that controls an electric device by communicating with the host control device. The vicarious inputting and outputting unit includes a standard board provided with a first control circuit which controls the electric device and at least one of an input circuit and an output circuit for a standard electric device. The first control circuit has an extension terminal for connection to an extension board provided with at least one of an input circuit and an output circuit for an extended electric device and is provided so as to be able to operate in response to respective specifications of plural kinds of extension terminals, and a specification of the extension terminal is set through communication with the host control device.
