Thermal mitigation features may be included in a Universal Serial Bus (USB) cable assembly or in the USB receptacle portion of a device. In one aspect, one or both ends of a USB cable jacket may have greater thermal conductivity than the portion between them. The portion having the greater thermal conductivity may dissipate excess heat from the cable into the environment. In another aspect, a USB cable connector or the USB receptacle portion of a device may include a thermoelectric heat pump. The thermoelectric heat pump may move excess heat from the cable assembly or receptacle into a portion of the cable assembly or device that dissipates the heat into the environment.

A plug-in power adapter is described. The plug-in power adapter may comprise a plug having a plurality of prongs, wherein a first prong of the plurality of prongs is adapted to receive power; a transformer coupled to receive the power by way of the first prong of the plurality of prongs, wherein the transformer is adapted to generate a power signal on a power signal line coupled to the transformer; an input portion comprising a control button, wherein the control button is accessible by a user of the plug-in power adapter; and a plurality of contact elements on a surface of the plug-in power adapter and accessible by the user of the plug-in power adapter; wherein a contact element of the plurality of contact elements is adapted to receive a control signal.

An AC adapter having electronics for converting AC electricity to DC voltage is presented herein. The adapter includes an adapter housing, a plug and a built-in extension cord contained within a storage cavity defined by the adapter housing. The extension cord extends from the electronics to the plug. In a first engagement state the plug is mechanically engaged to the adapter housing such that the plug body completely covers the opening into the storage cavity, and the adapter housing and plug are a single structure that may be plugged directly into a wall outlet. In a second engagement state the plug is removed from the mechanical engagement with the adapter housing, and may be plugged into an outlet some distance from the adapter housing as limited by the length of the extension cord, which maintains electrical connection between the plug and the electronics within the adapter housing.

A main shell seat has a first receiving slot, a second receiving slot and an insertion portion. A first conductive sheet is disposed in the first receiving slot. A second conductive sheet is disposed in the second receiving slot. A separation shell seat has a separation receiving slot and a sliding rail, and the separation shell seat is coupled to the main shell seat through the sliding rail inserting in the insertion portion, and a separation conductive sheet is disposed in the separation receiving slot.

The present invention provides an electrical connector, cables, an insulation sleeve, a latch member, and a fastener. One end of the electrical connector is provided with a coupling portion, and wiring holes are defined on the other end of the electrical connector opposite to the coupling portion. The cables are inserted in the wiring holes respectively. The insulation sleeve covers the junction of the electrical connector and each of the cables, and the coupling portion protrudes out of the insulation sleeve. The latch member is disposed corresponding to one side of the electrical connector. The fastener is disposed corresponding to the other side of the electrical connector.

A device with a plug attachment; a power plug extending from the plug attachment; adjustable power tongs; a fastening mechanism configured to fasten the power plug to the adjustable power tongs; a plug attachment cover operationally connected to the adjustable power tongs; electronic components coupled to the power plug through which power is provided from a power source to the electronic components, the electronic components causing the plug-in network device to function as a wireless access point (WAP).

A peripheral device having a connector receptacle capable of identifying a master-slave mode includes a body and a connector module. The connector module includes a processing unit, an energy storage unit, and a connector receptacle. When the connector module is connected to an electronic device through a power positive terminal, a power negative terminal, a signal positive terminal, a signal negative terminal, and a transmission cable, the processing unit transmits a notification signal to the electronic device through the positive terminal of the signal and the negative terminal of the signal to notify the electronic device that the electronic device does not need to provide power to the peripheral device.

The present disclosure relates to telephone jack covering systems that advantageously render existing telephone jacks more attractive and useful.
