Embodiment Construction

[0046] Generally, different devices having circuits are connected through interfaces. For example, the first interface of the first electronic device and the second interface of the second electronic device are respectively provided with a plurality of pins, which are used to transmit data signals that need to be exchanged between the circuits on the first electronic device and the second electronic device , synchronous clock, ground signal, and other signals. When the first electronic device is electrically connected to the second electronic device, the first electronic device provides the second electronic device with the voltage required for its circuit operation and forms a loop ground signal through the first interface and the second interface. . Therefore, the first electronic device can be regarded as a power supply device providing a voltage signal, and the second electronic device can be regarded as a power receiving device receiving the voltage signal. However, it ...

Abstract

The invention relates to an interface, an electronic apparatus with the interface and a protection method thereof. The electronic apparatus comprises an interface, an application circuit an a protection circuit. The application circuit receives signals from the interface. The protection circuit is used for protecting the application circuit, and the protection circuit comprises a detecting end, a power signal input end and a power signal output end. If the detecting end detects the interface receives grounded signals, the protection circuit is on, and the power signal output end outputs the signals received by the power signal input end to the application circuit. And if the detecting end detects the interface does not receive grounded signals, the protection circuit is off, and the output end stops outputting the power signals, thereby protecting the application circuit and the electronic apparatus.

Description

technical field [0001] The invention relates to an interface for connecting different circuits in an electronic device that need to perform information exchange, in particular to an interface for protecting circuits during hot plugging. Background technique [0002] In the electronics industry, data exchange is required between electronic devices and among circuit modules inside the electronic device, and different electronic devices or circuit modules need to be connected through interfaces and extension lines. For example, in the mainframe of a computer, it is often seen that a plurality of circuit boards provided with circuits are connected through interfaces and cables. However, in actual use, when another circuit board is hot-swapped from the interface of one circuit board, the circuit board is often burned, thereby affecting the service life of the electronic device. Contents of the invention [0003] In order to solve the problem of electronic devices being burned ...
