A multi-port Universal Serial Bus Type-C (USB-C) controller with ground and supply cable compensation technologies is described. A USB-C controller includes a first power control circuit (PCU) coupled to a system ground terminal and a first ground terminal and a second PCU coupled to the system ground terminal and a second ground terminal. The first PCU receives a first ground signal indicative of a first ground potential at a first USB-C connector and adjusts a first power voltage line (VBUS) signal on the first VBUS terminal based on the first ground signal and the system ground. The second PCU receives a second ground signal indicative of a second ground potential at a second USB-C connector and adjusts a second VBUS signal on the second VBUS terminal based on the second ground signal and the system ground.

Exemplary portable electronic devices include a housing and a power connector interface. The housing has a power input opening and includes a controller, a rechargeable battery, and battery charging circuitry coupled to the rechargeable battery. The power input opening is sized to receive an electrical connector of a cable assembly. The power connector interface includes a power conductor, a ground conductor, and other conductors and is configured to attach to the electrical connector of the cable assembly. At least one of the other conductors is configured to receive a signal, and the controller is responsive to the signal and is configured to control the battery charging circuitry.

The embodiments of the present disclosure are directed to a replaceable socket device and an adapter. The replaceable socket device includes at least one adapting element and an adapter. Each of the at least one adapting elements includes a first polarity terminal, a second polarity terminal, and a third polarity terminal. The adapter includes at least one adapter interface, a first polarity adapting member, a second polarity adapting member, and a third polarity adapting member. When the at least one adapting element and the at least one adapter interface are engaged with each other, the at least one adapting element is electrically connected to the at least one adapter interface.

A connecting apparatus comprising a holding member and a conductive member. The holding member has holding portions. The conductive member has a plurality of held portions, a plurality of contact portions, a plurality of extending portions and a plurality of coupling portions. Each of the extending portions extends rearward in a front-rear direction from one of the held portions and protrudes rearward in the front-rear direction beyond the holding portion. The extending portions are positioned apart from each other in a right-left direction. The coupling portions are positioned apart from each other in the right-left direction. The coupling portions are positioned rearward of the extending portions in the front-rear direction. Each of the coupling portions couples two of the extending portions with each other. Two of the held portions, which are adjacent to each other in the right-left direction, are coupled with the two extending portions, respectively.

A connector assembly includes a male connector and a female connector. The male connector includes N pins with different lengths, and the N pins respectively correspond to N different transmission signals. The female connector includes N signal layers configured to transmit the N different transmission respectively, and each of the N signal layers includes N pass gates. One of the N pass gates of each of the N signal layers is configured to be coupled to a corresponding one of the N pins.

A power switching device, an electric energy storage system and an electric tool system are provided. The power switching device includes a plug connected to a power supply device and including an output terminal; and a power switching assembly connected to the plug and including a power switching member, the switching member is used for switching a coupling form of the plug. The power switching assembly further includes a control member for controlling the power switching assembly to move between different switching positions. The control member includes a switching button, and the switching position of the power switching assembly is switched by pressing the switching button.

A cable with ends having a body portion enabling rotatable electrical connector plugs to be deployed from a stored position to a ready position. The configuration of the body portion enables the connector plug to be electrically active only in the deployed ready position. The rotation mechanism provides tactile locking sensation. The design of the present cable enables multiple permutations of connector plugs to be provided on either the alpha or beta end of the cable.
