An electronic circuit includes an output generator and an over-voltage detector. The output generator is configured to output an output signal to an output terminal. In response to an amplitude of a voltage of the output terminal being greater than an allowable amplitude, the over-voltage detector is configured to output an over-voltage detection signal of a first logic value, such that elements included in the output generator are turned off. In response to the over-voltage detector outputting the over-voltage detection signal of the first logic value again before a reference time elapses after the first logic value of the over-voltage detection signal changes to a second logic value of the over-voltage detection signal, the turned-off elements remain turned off. In response to the over-voltage detector outputting the over-voltage detection signal of the second logic value during the reference time, the turned-off elements are turned on.

A safety socket includes a main body, a first and second conductive seat, a first and second electric connection plates, a first and second insulated member and a first and second conductive plates. A first and second position block projects outwardly from first and second chambers of the main body. The first conductive seat includes a first clamp couch having two first clamp arms, one of which is formed with a first recess permitting extension of the first position block. The second conductive seat includes a second clamp couch having two second arms, one of which is formed with a second recess permitting extension of the second position block. The present safety socket has lesser components, easy to assemble and low in manufacturing cost, double safety measures. Addition of a switch device enhances the anti-shock effect and prevents occurrence of electrical discharge phenomenon and/or arc light phenomenon.

The Multi-use Connector in brief enables wired and wireless interconnection between a wide range of devices with a variety of input and output terminals. The usages of this invention can range in application between audio and electrical charging, and backup charging. Further, this invention has circuitry that can enable the conversion of analog audio signals from an analog source to digital signals for further wireless transmission through an onboard wireless transmission system, or convert digital signals received wirelessly to analog audio signals for further usage as maybe needed. Also, a companion software application to the Multi-use Connector can be used on smartphone like electronic devices that can allow the reception and recording of digital audio and or video signals transmitted by the Multi-use Connector, and also over-the-air analog sound signals received by a smartphone's inbuilt microphone system i.e., both signals can be recorded into separate channels at the same time.

Telecommunications jacks and methods of their use and construction are described. One telecommunications jack is adapted to receive a plug, and includes a housing defining a port for receiving the plug, as well as consecutively arranged contact springs adapted to make electrical contact with the plug when the plug is inserted into the port of the housing along a first axis.

And a first end of the conductive path is coupled to ground via one of the first detect pins. A second end of the conductive path is coupled to the control unit via another one of the first detect pins.

Disclosed is an interface device capable of simultaneously connecting an audio device and charger to an electronic device. An interface device may enable an electronic device with a single USB type-C connector but no analog audio jack to connect to both an audio device and a charger through the USB type-C connector. The interface device may provide automated quick charging when connected with the charger but not with the audio device.
