On a round plug, outwardly directed detent hooks are arranged between a plug-in region and a contact carrier portion of an insulating body or a base portion of the round plug housing. A mating connector has, on a plug-in side of a threaded portion, an inwardly directed circumferential or interrupted detent lug. The detent arms do not need to reach through the threaded portion. The detent arms can therefore be made particularly strong, and the inner thread can be continuous. The retaining forces of the locking/screwing are thus very high, and the detent arms for example can be integrally molded on a plastic insulation body, and thus be formed in one piece therewith, for simplified production. Operation and manufacture are significantly simplified.

A connector includes a housing and a release button. The housing defines a recess for receiving a latch member of a receptacle. The release button is operable to cause displacement of the latch member from the recess and has a surface that aligns with a surface portion of the housing when disconnected from the receptacle. The surface of the release button protrudes from the surface portion of the housing when the connector is connected to the receptacle to provide a visual indication that the connector is connected to the receptacle.

An electrical connection base providing support for heavy expansion cards includes a pedestal and a supporting element. A socket is defined on the pedestal. The supporting element includes installation and support portion. A through hole is defined on the installation portion, which is portion set outside the pedestal, the pedestal entering the through hole. The support portion has a first slot, and the first slot runs through the end of the support portion away from the installation portion. The portion of the expansion card or other element plugged into the socket and outside the pedestal is inserted into the first slot. The groove wall of the first slot is in contact with the element, the support portion thereby supports the card or element and prevents strain and deformation.

A connector combination structure is provided. The connector combination structure includes a first connector and a second connector. The first connector includes a first joint and at least one wedging portion. The second connector includes a housing, a second joint and at least one wedging arm. The second joint and the wedging arm are disposed in the housing. The wedging arm is adapted to be rotated between a first arm position and a second arm position. The first joint is adapted to be inserted into the housing to be connected to the second joint. When the wedging arm is located in the first arm position, the wedging arm is adapted to wedge the wedging portion. When the wedging arm is in the second arm position, the wedging arm is adapted to release the wedging portion.

A plug connector includes a housing, a built-in circuit board partially located in the housing, and a cable electrically connected to the built-in circuit board. The housing includes a mating surface. The built-in circuit board includes a tongue plate and a number of conductive pads provided on the tongue plate. The housing includes an extension plate extending along a mating direction of the plug connector. The tongue plate and the extension plate protrude beyond the mating surface along the mating direction. The extension plate further protrudes beyond the tongue plate along the mating direction. Two lateral sides of the plug connector also respectively include slots extending through the mating surface. As a result, the insertion reliability of the plug connector of the present disclosure is improved.

An ejector for electric vehicle charging connectors is provided. An ejector can be configured to be secured on the inside of the charging port of an EV and to automatically eject or push the charging connector from the charging port. The ejector may include a pusher assembly that selectively extends through an opening in a housing forming the socket of the charging port. The ejector may also include a driver assembly that forces the pusher assembly through the opening to eject the charging connector while allowing the pusher assembly to be freely withdrawn when the charging connector is inserted.

A traction battery assembly according to an exemplary aspect of the present disclosure includes a traction battery, an electric machine, an electrical harness assembly, a protrusion adjacent the electrical harness assembly. The protrusion is configured to move from a first position to a second position in response to a loading event. When the protrusion is in the first position, the electric machine is electrically coupled to the traction battery through the electrical harness assembly. When the protrusion is in the second position, the electric machine is electrically decoupled from the traction battery.

A power connection assembly for an appliance includes a receptacle that has an inner wall. The inner wall defines a cavity. A channel is defined by the inner wall and is in communication with the cavity. A power cord is configured to be at least partially received by the cavity of the receptacle. A cap is rotatable between a locked position and an unlocked position and is configured to at least partially encase the power cord. A protrusion extends radially from the cap. A switch is positioned proximate the channel and is operable between an open position and a closed position. The protrusion is received by the channel and is configured to move the switch to the closed position.
