A charging control box detachable charging cable system includes a vehicle cable having a vehicle terminal on one end for connection to a first connection terminal of a charging control box or an external power source, and an outlet on the other end for connection to a charging inlet of a vehicle. The system also includes a portable cable having one end for connection to the external power source, and a portable terminal provided on the other end for connection to a second connection terminal of the charging control box. The vehicle terminal has a first corresponding key configured to be engaged and coupled with the first key of the first connection terminal, and the portable terminal has a second corresponding key configured to be engaged and coupled with the second key of the second connection terminal.

A magnetic latching connector for making electrical connections between cables, electrical power and signal sources, equipment and the like in a variety of medical and other applications in which it is desired to have the connection maintained with a predetermined amount of magnetic attractive force. The magnetic latching connector generally includes male and female connector components. The male and female connector components comprise male and female couplings and male and female coupling housings. The male and female coupling housings enclose electrical connections between the male and female couplings and electrical cables. Recessed within the male and female couplings are electrically conductive pins and sockets and male and female magnetic latching elements. When the male and female connector components are coupled, the pins and sockets provide electrical connections and the recessed magnetic latching elements provide a predetermined magnetic attraction force to maintain the connections.

A connector keying system includes at least one keying device including a flange portion and a keying portion. The flange portion includes a front surface and a back surface. Each of the front surface and the back surface extend substantially parallel to a flange plane. The flange portion further includes a connector aperture extending through the flange portion. The keying portion extends around an aperture perimeter of the connector aperture and projects outward from the flange portion. The keying portion includes and extends between a first key end located at the front surface and a second key end opposite the first key end. The second key end defines a keying perimeter about the connector aperture. The keying portion has a height between the first key end and the second key end and the height is inconsistent between the first key end and the second key end along the keying perimeter.

An assembly (10) includes a first connector (12), and a second connector (14) mobile in axial translation relative to the first connector, a first part (16) attached to the first connector, and a first sleeve (18) axially rotatable relative to the first part between a first plurality of positions, a first blocking device (20) blocking the first sleeve, a second part (22) attached to the second connector, and a second sleeve (24) axially rotatable relative to the second part between a second plurality of positions, a second blocking device (26) blocking the second sleeve. The first sleeve, the first part, the second sleeve, and the second part have shapes that provide a coding that allows connection only if the position of the first sleeve matches the position of the second sleeve.

A control box includes a housing, and a plurality of positive and negative plug connectors protruded and fastened on a cable let-out surface of the housing. The plurality of positive and negative plug connectors are different from each other, and each of structures of the plurality of positive and negative plug connectors is selected from a group including a dual male plug transmission-end structure and a dual female plug transmission-end structure.
