A connector assembly has a device for dual position confirmation and is able to not only accurately show whether female and male connectors have been completely fastened to each other at an appropriate position by a lever using the device for dual position confirmation, but to show the fastened state and position of the lever.

An electrical plug device includes a connector housing pluggable with a mating housing, a connection aid engageable with the mating housing, a position assurance element held at the connector housing and displaceable from an open position to a securing position, and a blocking mechanism. The connection aid is movable from a plugging position to a holding position. The connector housing in the plugging position is connectable to the mating housing. The mating housing in the holding position is held at the connector housing. The connection aid in the open position is movable from the plugging position to the holding position and in the securing position is fixated in the holding position. The blocking mechanism blocks the position assurance element in the open position and has a release element with which the blocking mechanism is released in a state of the connector housing and the mating housing being plugged together.

The present disclosure provides an electrical connector comprising first and second connector housings configured to be coupled and uncoupled from one another via a mate assist mechanism comprising a lever. The lever is configured to be positioned, when the first and second connector housings are in an uncoupled state or the second connector housing is absent, at a pre-lock position, whereby a blocking element of the lever is configured to cooperate with a blocking surface of the first connector housing, the electrical connector comprising a lever seal and a panel seal.

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.

An electrical connector housing is provided with at least one locking clip, which is mounted pivotably via a bearing pin and has a locking region and an actuation region. In order to reversibly lock the electrical connector housing to a mating electrical connector housing, the locking region engages overbearing journals integrally moulded on the mating electrical connector housing. The locking clip has a locking device or means for blocking the pivot movement of the locking clip. In this manner, an accidental release of the plug-in connection can be prevented.

A service plug includes first and second main terminals, first and second signal terminals, a lock part that locks a lever to a second connector housing to regulate rotation of the lever in a state in which the lever is positioned at a half-engaged position between a completely engaged position and a non-engaged position, and a lock releasing part that releases a lock state. A configuration is made such that, as the lever is rotated from the completely engaged position to the half-engaged position, part of a plurality of contact pieces of the second main terminal that is brought into elastic contact with the first main terminal at a position displaced in an approaching direction, and the other part of the contact pieces maintains elastic contact at a position that is not displaced in the approaching direction and a separating direction.

A lever-type connector includes a housing, a lever and a cover. The housing is to be fitted with a mating housing. The lever is pivotably mounted to the housing and fits the housing with the mating housing by pivoting. The cover is mounted to the housing to cover an outer periphery of an electric cable drawn out from the housing. The housing is provide with a deflectable lock arm. The lock arm has as a base end, a root part integrally mounted to the housing at a side where the housing faces the cover and holds the lever at a pivoting completion position of the lever. The cover is provided with a protective wall arranged opposite to the root part of the lock arm.

A lock lever of a second connector has a first engaged part and a second engaged part. A frame of a first connector has a first engaging part and a second engaging part. The first engaging part is engaged with the first engaged part in a locked state where the lock lever is at a lock position. The lock lever has the elastic part that is elastically deformable in the horizontal direction. The elastic part has a second engaged part and is elastically deformed in the horizontal direction in the locked state to bring the second engaged part into contact with the second engaging part.

On-board power supply connector, in particular for high-voltage on-board power supplies, comprising, a first connection part arranged in a first housing part, the first housing part having a longitudinal extension along a longitudinal axis and having an end-face opening, and the first connection part being mounted in the first housing part such that it can move along the longitudinal axis, a second connection part arranged in a second housing part, the second housing part having a longitudinal extension along a longitudinal axis and having an end-face opening, characterized in that, in the connected state of the connector, a fastening lever which can be pivoted about an axis perpendicular to the longitudinal axis is arranged on one of the housing parts and, in the connected state of the connector, engages with a fastening means on the other housing part, wherein, in the connected state of the connector, the longitudinal axes of the first and second housing parts extend collinearly and the second housing part is fixed relative to the first housing part at least in the longitudinal direction and the second connection part is in mechanical contact with the first connection part, characterized in that the first connection part is resiliently mounted in the first housing part along the longitudinal axis by a spring element.

The invention provides an easy lock connector with unlock structure applied to a flat wire and a circuit board. The flat wire has a notch and a ground wire on the two sides of a head end respectively. The easy-lock connector includes an upper housing, a lower housing, a rubber core and a terminal. After the notch of the flat wire is buckled by a stopper of the lower housing, by pressing a pressing member of the upper housing, the pressing member applies an external force to an elastic member of the lower housing to deform the elastic member. An extension arm of the lower housing is linked by the elastic member to cause the stopper to act in one direction so as to release the state of the stopper from locking the gap. In another embodiment, the easy-lock connector can also achieve an electromagnetic shielding effect by adding a shielding iron shell.
