An electrical plug connector, comprising a plug connector housing, a locking securement means for locking the electrical plug connector with a corresponding electrical mating plug connector, and a securing element that is displaceable between a pre-latching position and a securing position. The securing element blocks the locking securement means in the securing position to prevent unlock in of the mating plug connector. In a first variant, the electrical plug connector housing forms a lead-in along which the securing element can be displaced into the pre-latching position. In a second variant, the securing element is in the plug connector housing and when the mating plug connector being plugged in, the securing element is mechanically loaded, and a plug connector housing guide guides displacement of the securing element from the pre-securing position into the securing position and the mechanical load is relieved in the displacement.

A connector assembly includes a connector, a mating connector and a lever unit mounted on the connector and having a locking element and a securing element. The connector and the mating connector are movable into a connected position in which the connector and the mating connector are conductively interconnected. The connector and the mating connector each have a contact carrier, each having a receiving opening. In the connected position, the lever unit is movable between a locking position and an unlocking position. In the locking position, the locking element is located in the receiving openings of both contact carriers, and in the unlocking position, the locking element is located outside the receiving opening of at least one of the contact carriers. In the connected position, the securing element is movable into a blocking position in which the securing element secures the lever unit in place in the locking position.

A connector includes: a terminal fitting; an electric wire connected to the terminal fitting; a first housing in which the terminal fitting is stored, the first housing constituting a fitting part with a counterpart connector; a seal member disposed so as to surround an outer periphery of the first housing; a front holder mounted on the first housing so as to prevent the seal member from coming out from the first housing; and a second housing including a short terminal, the short terminal being configured to allow a fitting state with the counterpart connector to be detected. The second housing is attached to the first housing and retained by the front holder in a state in which the second housing is displaceable in a direction intersecting a fitting direction with the counterpart connector in a posture in which the short terminal faces the counterpart connector.

A connector used in underwater environments includes a male connector with a sensing terminal and two power terminals, a female connector with a sensing terminal block and two power terminal blocks, and an elastic gasket set between the male connector and the female connector. When the male connector and the female connector are plugged into each other, and the male and female connectors squeeze the elastic gasket to form a large amount of deformation, the sensing terminal and the sensing terminal block are in contact with each other. When the male and female connectors squeeze the elastic gasket to form a small deformation state, the sensing terminal and the sensing terminal block are separated from each other, and the power terminals and the power terminal blocks are in contact with each other, thereby forming a waterproof protection mechanism.

A connector assembly comprises a first connector and a second connector. The first connector comprises a first housing provided with a stopper. The second connector comprises a second housing, a mating detecting member and a shift mechanism. The second housing is mateable with the first housing along a front-rear direction. The mating detecting member has an abutment portion. The abutment portion is movable in a direction intersecting with the front-rear direction by an operation of the shift mechanism. When the second housing is mated with the first housing under a state where the mating detecting member is positioned at a regulating position, the abutment portion abuts against the stopper, and the mating detecting member is moved from the regulating position toward an allowable position. The mating detecting member is positioned at the allowable position when a mating of the second housing with the first housing is completed.
