A connector assembly enables electrically safe disconnection and separation because it is possible to secure an interval between the point of time of separation of interlock terminals and the point of time of separation of power terminals when connectors are separated. The connector assembly can implement two steps of cutting power after restricting a lever in a locked state and then completely disconnecting connectors by additionally operating the lever by including an intermediate locking mechanism that restricts the lever for disconnecting connectors in a state in which interlock terminals of two connectors are separated from each other but power terminals of the two connectors are in contact with each other to disconnect and separate female and male connectors.

The invention relates to the field of electric vehicles, and particularly provides a direct-current charging gun and charging pile. The invention aims to solve the problem that a user, when operating a current direct-current charging gun, needs to make round trips back and forth between a charging pile and a charging gun to stop charging, pull out the gun and return the gun, thereby degrading the user experience. For this purpose, the direct-current charging gun of the invention comprises an unlocking mechanism, a safety mechanism and a communication mechanism, wherein the safety mechanism is connected to the communication mechanism and the unlocking mechanism separately; the unlocking mechanism is used for locking when the direct-current charging gun is in use, and for unlocking when the direct-current charging gun is not in use; the communication mechanism is configured to interrupt a direct current in the charging gun when being triggered; and the safety mechanism is configured not to trigger the communication mechanism in an unarmed state and to lock the unlocking mechanism, and triggers the communication mechanism first and then unlocks the unlocking mechanism during arming. It can be avoided that the user makes round trips back and forth between the charging pile and the charging gun, thereby improving the user experience.

An on-vehicle structure of a power converter includes a housing of the power converter mounted on a vehicle, a structure mounted on the vehicle, and a high-voltage connector attached to the housing. The high-voltage connector is configured to apply a voltage exceeding a predetermined threshold voltage, the high-voltage connector is positioned between the housing and the structure such that the high-voltage connector faces the structure in a removal direction of the high-voltage connector when the high-voltage connector is attached to the housing, and in a state where the high-voltage connector is attached to the housing, a length of a portion of the high-voltage connector embedded in the housing is determined so as to be longer than a distance between the high-voltage connector and the structure.

Cable connection assemblies for marine propulsion, and associated systems and methods are disclosed. A representative connection assembly includes a multi-conductor cable having two high voltage power conductor lines, two low voltage power conductor lines, two interlock lines, and two signal lines. The assembly further includes a connector having a connector body carrying connection elements corresponding to each of the conductor lines, interlock lines, and signal lines. In further representative embodiments, one or more of the connection elements can be housed in corresponding insulating bodies. In still further representative embodiments, the assembly can be configured so that the high voltage lines are the first to mate, and the last to un-mate, which, together with the interlock loop, can reduce or eliminate the likelihood for high voltage arcing.

A connector for a high-voltage connection for electrically connecting high-voltage components, in particular of an electrical drive system of a motor vehicle, said connector comprising at least one electrical contact arrangement, wherein the contact arrangement comprises at least one ring-shaped contact element; a first inner protective element, which is arranged within the contact element and projects relative to the contact element; and a first outer protective element, which at least partly surrounds the contact element and projects relative to the contact element, wherein the first inner protective element and the first outer protective element form a shock protection for the contact element.

An internally switched female receptacle or connector for use with IEC 60309-2 configuration plugs and the like. Various plug-latching and plug-actuated safety interlock arrangements coordinate strictly axial plug movement relative to the receptacle with the closing and opening of sleeve contacts and terminal pressure contacts. A continuous ground feature ensures grounding of the primary electrical circuit throughout plug insertion and withdrawal. An optional low-current lighting control circuit powers an LED status indicator. A modular clocking design enables variable angular positioning of the terminals during manufacture.
