Abstract: A connector unit includes a connector housing that has a front plate portion and two or more through-holes penetrating the front plate portion and communicating with an inside of the connector housing, two through-holes of the two or more through-holes are separately positioned at two vertexes, opposed to each other, of a rectangular surrounding an opening portion in the front plate portion, and when the connector unit is disposed, one of the two through-holes is situated on an upper side from the opening portion and serves as a cap attachment hole, and the other of the two through-holes is situated on a lower side from the opening portion and serves as a drain hole.

Abstract: A connector unit includes a cap that is attached to a connector housing and openably and closably covers an opening portion, the cap including an L-shaped arm made of an elastic material and having a support portion, a bent portion, and a hook portion, the cap being retained by the connector housing with the support portion being passed through a cap attachment hole of the connector housing, the support portion and the hook portion each have a thickness dimension smaller than a dimension of the cap attachment hole, a maximum dimension of the bent portion is larger than the dimension of the cap attachment hole, and the hook portion has a length dimension larger than the dimension of the cap attachment hole when viewed in a direction perpendicular to a plane including the support portion, the bent portion, and the hook portion.

Abstract: A control device that is mounted in a second vehicle which a first vehicle having a following travel function is detachably connected to or loaded on is provided. The control device includes a control unit configured to perform: detecting another vehicle that is within a predetermined range from the second vehicle in a state in which the second vehicle has the first vehicle connected thereto or loaded thereon and of which some or all of a scheduled travel route is the same as some or all of a scheduled travel route of the first vehicle after the first vehicle has been disconnected from the second vehicle; and transmitting following instruction information to the first vehicle and disconnecting the first vehicle from the second vehicle such that the first vehicle travels with the detected other vehicle as a preceding vehicle by the following travel function.

Abstract: Each of a feeding unit and a connector unit is provided with power supply ports and ground ports. In at least one of a connection of the power supply ports of the feeding unit and the power supply ports of the connector unit and a connection of the ground ports of the feeding unit and the ground ports of the connector unit, the number of parallel lines in at least a partial section is changed according to a length of the connection. In this way, a voltage drop between the feeding unit and the connector unit is adjusted.
