An electrical connector includes a main body, a first cover, and a second cover. The main body includes a first connection portion, a wire inlet portion, and an accommodating space between the first connection portion and the wire inlet portion. The first cover is pivotally connected to the first connection portion to be rotatable relative to the main body between a first position and a second position. When the first cover is at the first position, the accommodating space is opened for installation. When the first cover is at the second position, the first cover at least partially closes the accommodating space for protection. The second cover is connected to the first cover and separably encloses a wire inlet hole with the wire inlet portion. The second cover is movable relative to the wire inlet portion to adjust the size of the wire inlet hole.

Charging station for an electric or hybrid vehicle includes a wall, an electric cable, and at least one clamping collar fixed to the wall. The clamping collar has a shape that allows there to be, in a plane perpendicular to the direction in which the cable extends, at least three points of contact between the cable and the assembly formed by the clamping collar and the wall, so as to clamp the cable against the wall.

A tension relief for supply lines and a block-like clamping part therefor, which has a lateral surface designed as a clamping surface. The clamping surface of the clamping part is formed at least in one clamping portion by an elastic wall, which is delimited on the side facing away from the clamping surface by a cavity structure, which is formed by additional walls. The clamping part can be variedly used without modification on certain line diameters, in particular in a tension relief of a cable carrier or also in a connector housing.

A wall plate for covering an AC/DC wall outlet includes a generally rectangular or “designer” opening configured to receive the wall outlet. The wall plate includes one or more cord retention members. The cord retention member(s) protrudes from a front face of the wall plate. The retention member(s) protrudes far enough to allow the wall plate to seat on the outlet while a USB plug is in a corresponding DC outlet of the wall outlet. The retention member includes a slot configured to allow a mobile device-attachable plug to pass-through the slot in a first orientation but not a second orientation 90 degrees off from the first orientation. When the USB plug is in the DC outlet, it is in the second orientation relative to the slot.

A housing for an electrical connector includes a housing body having an opening receiving a cable in an insertion direction and a pair of cable covers hinged to the housing body at a proximal end of each cable cover of the pair of cable covers. The pair of cable covers extend away from the opening. Each of the cable covers is pivoted away from the other cable cover in a cable mounting position and each cable cover is pivoted toward the other cable cover to form a cable support sleeve supporting the cable in an operating position.

A signal communication socket for connecting a signal line includes a socket housing defining a signal line channel therein and a slot thereon to communicate with the signal line channel, the slot having at least a first wall surface, and an elastic member detachably inserted into the slot, the elastic member abutting against the first wall surface through elastic extension when no external force is applied, thereby being positioned at the socket housing, wherein one side of the elastic member toward the signal line channel defines a part of a periphery of the signal line channel.

When the USB plug is in the DC outlet, it is in the second orientation relative to the slot.

An adjustable transition coupler for coupling AC/MC to conduit, having a body with a hollow cylindrical section and an extension member, the cylindrical section having a slot to allow passage of a stop plate. The coupler has an insulator (armor stop) with a hollow bushing at one end for insertion into a cavity of the cylindrical section and a stop plate extending radially outward, the stop plate movable by an adjustment screw between minimum and maximum deflections. The stop plate stops AC/MC from passage into the cylindrical section. The hollow bushing stops the conduit positioned in the hollow cylindrical section from passage into the extension member. The coupler has a strap to secure AC having different outer sheath diameters. Snap tabs on the insulator fit into holes in the body while a rib on the stop plate passes through a notch in the slot to facilitate installation and minimize movement.

Provided is a technique of reliably easily making connection even in a case where the thickness of a cable is changed in an electric connector for a shield-equipped multicore cable. The electric connector includes a tubular conductive shell 30, covers 40 and 50 provided outside the shell 30 to cover at least part of the shell 30, and a movable cover 60 coupled to the cover 50 through a rotary shaft 63. The cover 40 has locking pieces 41 on a cable side. The movable cover 60 has locking pieces 61 to be engaged with the locking pieces 41. At least one of the locking piece 41 or the locking piece 61 includes multiple locking pieces arranged along a circumferential direction of a circle about the rotary shaft 63. The locking pieces 41 and the locking pieces 61 form a ratchet mechanism, and have such a structure that the locking pieces 41 and the locking pieces 61 are movable in an approaching direction and movement in a direction in which the locking pieces 41 and the locking pieces 61 are separated from each other is restricted.

A signal communication socket for connecting a signal line includes a socket housing defining a signal line channel therein and a slot thereon to communicate with the signal line channel, the slot having at least a first wall surface, and an elastic member detachably inserted into the slot, the elastic member abutting against the first wall surface through elastic extension when no external force is applied, thereby being positioned at the socket housing, wherein one side of the elastic member toward the signal line channel defines a part of a periphery of the signal line channel.
