System, methods, and apparatuses for indicating the configured port width for ganged-style data connectors. An exemplary apparatus comprises a plurality of connectors supporting data connections and a plurality of visual indicators. The plurality of connectors are capable of being configured with two or more of the plurality of connectors ganged together to provide increased data width connections. Each or the visual indicators is associated with one of the plurality of connectors. An electrical circuit drives the plurality of visual indicators and is configured to control the visual indicators to visually indicate a configured port width for each data connection supported by the connectors, including those formed by ganging together two or more of the connectors.

An electronic device system can include an electronic device. The electronic device can include a receptacle, and a device logic driving status unit configured to generate a status signal indicating activity of the electronic device, and a communications cable. The communications cable can include a first plug configured to connect to the receptacle and receive the status signal, wherein the first plug includes a status indicator configured to indicate activity of the electronic device based on the status signal.

An electricity supply tool holder for a machining center is provided, and has: a holder body, a stationary coil portion, a rotating coil portion, a lateral fixing portion, and an electrical machinery. The stationary coil portion is provided with a primary coil therein; the rotating coil portion is correspondingly provided with a secondary coil therein; and the lateral fixing portion is fixed on a side of the stationary coil portion used for removably combining with a machining center. When the tool holder is rotated, an external electric power/signal can be transmitted through the lateral fixing portion to the primary coil, then inducing the secondary coil, then the electric power/signal is transmitted to the electrical machinery. Additionally, the lateral fixing portion can be switched into a locked position to temporarily limit rotation, so that it can be used in a machining center of an Automatic Tool Changing (ATC) system.

A cable connector is provided. The cable connector includes a housing with a proximal end and a distal end. The distal end is configured for insertion into a data port of a computer chassis. The proximal end is configured to receive at least one data cable. The cable connector includes a pull tab comprising an optically transparent material. The pull tab includes a body with a distal end connected to the housing and a proximal end extending past the proximal end of the housing. The pull tab includes a shank protruding from the body. The shank includes a polished surface aligned with a light output of the computer chassis when the distal end of the housing is inserted into the data port such that light from the light output enters the shank through the polished surface and is distributed through the transparent material to illuminate the pull tab.

A network card or the like with two or more connectors having reflecting sides, where a light emitter is positioned between or behind the connectors and emit light toward the reflecting sides which act as a wave guide and guide the light to an opening between the connectors and toward the surroundings.

A card edge connector includes an insultive housing, a plurality of conductive terminals retained in the insultive housing and a metal frame retained in the insultive housing. The insultive housing defines two sidewalls extending along a longitudinal direction and two endwalls connected to the longitudinal ends of the sidewalls. The metal frame is integrally formed in the insulative housing and defines an elongated flat portion and a pair of fixing portions extending downwardly from both longitudinal ends of the flat portion, the flat portion is embedded into an upper portion of the insulative housing.
