A connector includes a housing provided with an accommodating cavity and a first opening communicating with the accommodating cavity; a circuit board disposed in the accommodating cavity and provided with a first signal connection point; a connection head disposed on the housing and including a second signal connection point for external device connection; and a switch disposed in the first opening, being respectively connected to the first signal connection point and the second signal connection point. The switch is used for controlling the connection or disconnection between the first signal connection point and the second signal connection point. In the above-mentioned manner, the connector and a heavy load may be disconnected by the switch when the connector is pulled out, so that risks of instant ignition and short circuit caused by the connector pulled out may be avoided, and safety accidents may be reduced.

A cover for an electrical receptacle including a faceplate. The cover also includes a first transmission tab configured to be electrically connected to a first power line of the electrical receptacle and a second transmission tab configured to be electrically connected to a second power line of the electrical receptacle. Additionally, the cover includes a device (such as a light source, circuit, port, or sensor) in communication with the first transmission tab and the second transmission tab.

A power cord slide connector coupling includes a power cord, a low-profile connector coupled with the power cord, a receptacle including a housing with a concave opening sized to receive the low-profile connector in an insert direction, and a plug disposed in the receptacle and configured to electrically engage the low-profile connector. The plug includes contact members that are positioned such that with the low-profile connector in the concave opening, the plug engages the low-profile connector by displacing the low profile connector in a connect direction, perpendicular to the insert direction.

A submersible cable connector for connecting a plurality of cable ends is provided. The submersible cable connector includes a connector body and an encapsulation member covering the connector body. The connector body has one or more cable receiving apertures or cavities and one or more fastener receiving apertures in communication with the cable receiving apertures. The encapsulation member includes integrally molded tubular cable ports in communication with the cable receiving apertures, spaced apart tubular fastener ports in communication with the fastener receiving apertures, and tethered sealing cap assemblies monolithically or integrally formed into the encapsulation member, and each configured to seal respective one of the fastener ports.

An electronic device includes: a casing having an opening that houses a connection terminal inside; and a terminal cover that seals the opening such that the connection terminal is not exposed. The terminal cover includes a lid that seals the opening and a fixing part that fixes the terminal cover to the casing. The lid includes a protrusion and a cushion member, the cushion member being mounted around the protrusion and having a surface lower than a surface of the protrusion. The cushion member seals the opening by being in close contact with a member provided around the opening.

A connection assembly includes a first housing part, a second housing part pluggable with the first housing part, and a joint connector held between the first housing part and the second housing part. The first housing part has a plurality of contact element receptacles and a plurality of latching elements. The latching elements latch a plurality of contact elements in the contact element receptacles. The second housing part has a locking section locking one of the latching elements in a latching position. The joint connector connects at least two of the contact elements.

Provided is a molding method of a sealing cover, realized by setting up a sealing cover mold, the mold includes a cavity and a core group arranged in the cavity, including setting up a first core and a second core, the mold opening direction of the first core and the second core are not parallel. The present application does not need a process hole to perform the injection molding of the sealing cover with a fastening structure, whose sealing is also better.

A connector unit comprises: a connector that has terminals connected to terminal parts of electric wires, and a housing that holds the terminals; and a cylindrical connector cover that is formed from an elastic material and that covers the housing. The connector cover has an annular seal part provided at a position at which it is possible to contact a mating connector-side surface in a fitted state with the mating connector.

A protective cover for an electrical conductor comprises a substantially tubular cap surrounding the electrical conductor. The protective cover further includes a substantially disc-shaped flange comprising a bore surrounding the electrical conductor in a liquid-tight manner and an outer contour strictly inscribed in an inner contour of the tubular cap facing disc-shaped flange. The tubular cap also comprises at least one perforation arranged at a low point of the tubular cap. In one example, the protective cover is used for a heating element for an exhaust line.

An assembled waterproof and dustproof structure for charging devices, which includes a charging device casing with a first opening, a cable cover assembly including a base provided with an USB connection interface and an accommodating space, a bracket structure with a second opening, and a cover covering the USB connection interface to form a waterproof and dustproof protective cover. The first opening, the USB connection interface and the second opening are aligned with each other. The cable cover assembly, the charging device casing and the bracket structure utilize a set of snap-type components respectively disposed on the cable cover assembly and the bracket structure to form a waterproof and dust-proof snap-fit structure that closely fits in sequence from outside to inside.
