A variety of active cover plate configurations with prongs configured to contact side screw terminals of electrical receptacles are described.

A connector is realized that can simplify an electrical connection and a physical connection between a connector-related component such as a housing or a wiring part, and a power storage element. A connector includes a housing, a wiring part, and a power storage element. The power storage element is attached to the housing while being held by the housing. The power storage element is configured to be charged with power supplied via the wiring part, and discharge via the wiring part.

The present disclosure relates to a charger and a charger system, a charger having a removeable cover, as well as particular charger and adapter engagement configurations that provide robust, operative, and resealable association between the charger and adapter. The present disclosure also provides users the ability to forego a fixed, factory-provided aesthetic appearance of their chargers by providing the ability to customize the charger in accordance with an end-user's own preference/style.

A portable power adapter includes a housing containing within it a battery chamber adapted to receive a selected battery pack, a circuit overload protector and a terminal connector selected to electrical couple to a selected DC load, and a mounting portion. A portable power adaptor may include an integrated voltage regulator, and a hermaphroditic SAE step connector. A portable power adaptor may include a plurality of power adapters electrically coupled to comprise a common power source and output.

A rotatable power plug assembly is disclosed, which comprises: a first connection module, a second connection module and a plug module, wherein the second connection module is connected between the first connection module and the plug module. According to the present invention, the first connection module comprises a first base that is disposed on a housing of the power device, and there are two first conductive pins and two second conductive pins provided on the first base. Moreover, the plug module comprises two prongs and two electrical units electrically connected to the prongs. The two electrical units contact with the first conductive pins and two second conductive pins through the second connection module. By such arrangement, the rotatable power plug assembly according to the present invention has multiple advantages, including: comprising elements and units can be simply assembled, modular design, high durability, and high security.

An integrated device includes a power adapter and a wireless module. The power adapter includes a charging plug and a first connector. The wireless module includes a second connector mateable with the first connector. Each of the power adapter and the wireless module is an independent device. In addition, the power adapter and the wireless module can be detachably combined together through the first connector and the second connector. With this arrangement, when the power adapter and the wireless module are used separately, their respective functions can be achieved. When the power adapter and the wireless module are used in combination, the wireless module can be powered by the power adapter, thereby improving the convenience of using the integrated device.

A wetmate connector includes a plug and receptacle. The plug includes a plug body and the receptacle includes a receptacle body. The plug includes a recess circumscribing its forward end, adjacent to a coarse alignment feature and rearward of a front surface of the plug body. The coarse alignment feature includes a series of three truncated cones, the first and third of the cones including substantially congruent faces, the first and second cones being joined at their maximum diameter and the second and third cones being joined at their minimum diameter. The receptacle body includes a fastener adapted to cooperate with the recess in the forward end of the plug, to latch the plug and receptacle together when mated.

An ROV, diver, or stab, wet mateable connector plug front end housing includes a housing front section; a locator mount section; and a seal section axially in series with one another. The housing front section includes a plug coarse alignment feature on an outer surface of the housing front section, adjacent to a front surface of the housing front section and radially outward of a central axis of the housing. There is a circumferential groove on the outer surface of the housing front section, axially displaced from and rearward of the coarse alignment feature, the groove being adapted to receive a latch of a wet-mateable connector receptacle front end housing. The plug coarse alignment feature includes a bullnose feature. A plug fine alignment feature is formed in the outer surface of the housing front section, aligned with and located radially outward of the central axis of the housing.

A dry mate cable connection includes a data cable. The data cable includes a plurality of electrical conductors and at least one electrically insulating outer layer surrounding each data conductor, whereby the data conductors are electrically insulated from one another. The cable includes a termination end. The outer layer of each conductor is physically in contact with an outer layer of an adjacent conductor, except at the termination end. The plurality of electrical conductors at the termination end are physically separated from one another by a single electrically insulating overmoulded cable termination housing. The housing is in contact with at least part of the electrically insulating layers of each of the electrical conductors.

A subsea wet mateable connector includes a plug and a receptacle. The plug includes a plug body and a shuttle pin moveably mounted in a socket contact. The receptacle includes a receptacle body and a receptacle pin. The connector further including a secondary diaphragm mounted to the plug body and a primary diaphragm mounted to the plug body outside the secondary diaphragm. The primary diaphragm and secondary diaphragm are spaced from one another in a demated state, allowing fluid flow in the space formed therebetween. The primary diaphragm and secondary diaphragm are sealingly engaged in a mated state, forming a continuous protective layer over the receptacle pin in a mated state.
