A connector waterproofing structure watertightly seals a gap between openings of cavities of a pair of housings which accommodate terminals. In the structure, the pair of housings includes annular members formed at each of ends of the openings. The annular members are made of resin, protrude and surround the openings, either one of the annular members is formed into such a shape to be pressed to an inner peripheral surface or an outer peripheral surface of the opposite annular member, when the pair of housings are fitted together, and the inner peripheral surface or the outer peripheral surface are obliquely formed so that the wall thickness of the opposite annular member is gradually increased from the distal end toward the back.

An electrical connector socket is provided, which has a locking device with which an electrical connector can be locked to the electrical connector socket when plugged in, wherein the locking device is arranged at least partly inside the electrical connector socket and protrudes at least partly from the electrical connector socket on the plug-in side. The electrical connector is provided for transmitting high currents and signals, wherein the electrical connector as a locking contour, into which a locking device of an electrical connector socket can engage, wherein the locking contour is arranged on the electrical connector on the plug-in side.

Some embodiments relate generally to the field of electrical installations. In particular, some embodiments relate to an electrical socket device including at least one mechanism for locking and unlocking a corresponding electrical plug. More precisely, some embodiments relate to the electrical sockets and plugs of couplers, such as those defined by International Standard IEC 60320, for example of type C13 and type C19. These (coupler) sockets and plugs are applied or used in particular in a building that has a network, for example of LAN (Local Area Network) type, or in a data center, where several items of electrically powered equipment are installed.

A method includes plugging a plug into a socket, wherein the plugging includes pushing the plug into the socket at least up to a point that a latch clicks into the plug and locks the plug in place. Pressing down on a lever that rotates around an axis causes the lever to be pushed down. This results in the latch moving away from the plug and unlocking the plug from the socket, to thereby allow the plug to be separated from the socket.

A connector assembly (1) including a first connector unit (2) and a second connector unit (3) interconnectable with respect to each other. The first connector unit (2) includes at least one connector (5) arranged at least partially inside a plug housing (4). The at least one connector (5) is operatively connected to the plug housing (4) by a latching mechanism (7) which provides an engaged configuration in which the at least one connector (5) is latched with respect to the plug housing (4) and a disengaged configuration in which the at least one connector (5) is disengaged from the plug housing (4).

An electrical connector may include an insulating body, metal terminals exposed in a mating port of the insulating body, and a metal housing that includes walls. The walls may encircle the insulating body such that a first space is located between a first side of the insulating body and a first wall of the metal housing, a second space is located between a second side of the insulating body and a second wall of the metal housing, and a length of the first space is different from a length of the second space. The first and second walls may face in opposite directions. The mating port may receive a portion of a mating connector. The first wall may include first latching portions in communication with the first space, and the second wall may include second latching portions in communication with the second space.

An anti-loosening light device includes a light bulb and a light socket. One end of the light bulb is screwed into the light socket and is detachably connected to the light socket. The light bulb includes a bulb head and a bulb body. The bulb head is connected to the bulb body. The bulb body is provided with a bulb body positioning part. The bulb body positioning part is connected to the light socket. The light socket includes a socket body and socket limiting parts. The socket limiting parts are connected to the socket body. One end of the light bulb is inserted into the socket body. The bulb body positioning part is installed on the socket limiting parts. The bulb body positioning part and the socket limiting parts are engaged with each other.

A circuit board module including a circuit board body, a connector, and a release component is provided. The connector is disposed on the circuit board body and includes a base body and a rotating button rotatably disposed on the base body. The release component is disposed on the circuit board body and includes a linking member. The linking member is movably disposed beside the rotating button and does not contact the rotating button under normal conditions. When an external force triggers the release component, the linking member is driven to contact the rotating button, so that the rotating button rotates relative to the base body. In addition, a release component is also mentioned.

An unlocking element (17) for electrical plug-in connections, for acting on an elastically deflectable or displacable locking arm (16) of a locking arrangement (16, 17). The unlocking element (17) has at least one actuating tab (21), configured to be touched by a user and is coated with or produced from electrically insulating plastic. The center point (Z) of the actuating tab (21) and a longitudinal center axis (L) of the connecting portion (18) of the unlocking element (17) are offset with respect to one another radially in relation to this longitudinal center axis (L). An electrical plug-in connector for producing an electrical plug-in connection with a complementary plug-in connector is provided with a locking arrangement (16, 17) for the complementary plug-in connector, with the unlocking element (17).
