The present disclosure described devices, components, connectors, and cables that connect an audio-visual device to an external antenna. Some embodiments describe a device connector for connecting the audio-visual device to an external cable. The device connector may include a supply port that is configured to receive power, data signals, and/or some combination of power and data from a source external to the audio-visual device. The device connector may also include an antenna port that is configured to connect the audio-visual device to an external antenna that is, for example, part of the same. Additionally, the device connector may include a detection mechanism that detects the presence of an antenna connection in the antenna port. When an antenna connection is detected, the audio-visual device may be configured to use one or more external antennas connected via the antenna connection to send and receive, e.g., WiFi signals.

A connector-board assembly and an electronic apparatus detect damage to a receptacle connector. The connector-board assembly includes a receptacle connector and a board on which the receptacle connector is mounted. The receptacle connector has a tongue portion having electrodes at an approximately intermediate portion in a vertical direction of a plug insertion hollow portion. The tongue portion includes insulating layers provided above and below a metal plate and includes the electrodes on the surfaces of the insulating layers. The metal plate includes a first portion and a second portion which extend from a base end side toward an opening side and are electrically conductive to each other on the opening side. The first portion is connected to a signal input port on the board and connected to a power supply via a pull-up resistor. The second portion is connected to the ground.

A USB device includes a base, a circuit board disposed on the base and having front-end and rear-end portions and a ground circuitry, an upper cover, solder points, a switch and a button mount. The rear-end portion is used for inserting into a connection port of a computer terminal. The upper cover covers the front-end portion and has an opening. The solder points are formed on the front-end portion and coupled to the ground circuitry. The switch having a metal cover is soldered to the solder points for controlling wireless connection between the computer terminal and an external device. The button mount is movably disposed through the opening and sleeves the front-end portion for triggering the switch. An electrostatic discharge entering from the opening can pass through a first guide hole of the button mount and is conducted to the ground circuitry via the metal cover and the solder point.

An electrical connector includes a housing having a front end and a rear end, an insulator including a tongue portion disposed at the front end and a base disposed at the rear end, and plural terminals including plural ground terminals, plural power terminals and plural signal terminals. Each of the plural terminals has a first contact portion, a second contact portion and a connection portion connecting the first contact portion with the second contact portion. The first contact portions are disposed on surfaces of the tongue portion in a widthwise direction perpendicular to a direction from the front end to the rear end, and the second contact portions are extended out from the base. Widths in the widthwise direction of the second contact portions of the plural ground terminals and the plural power terminals are larger than a width of the first contact portion respectively thereof.
