Adapter and using method thereof

Abstract

The embodiment of the invention discloses an adapter and a using method thereof. The adapter comprises a shell, a three-wire plug is arranged on one side of the shell, at least one three-hole socket is arranged on the other side of the shell, and a first end, a second end and a third end of the three-wire plug are correspondingly and electrically connected with the first end, the second end and the third end of the three-hole socket respectively; at least one group of input and output interfaces and a first resistor are also included; each input and output interface comprises an input interface and an output interface, and the input interface and the output interface are correspondingly and electrically connected and used for transmitting direct-current electric signals; a negative electrode of the input interface is electrically connected with the first end of the first resistor, and the first end of the three-wire plug is electrically connected with the second end of the first resistor; and the first end of the three-wire plug is a ground wire end. The adapter provided by the embodiment of the invention can effectively remove an induced current generated by a low-voltage end, eliminates an induced electricity phenomenon, and improves user experience.

Description

technical field [0001] Embodiments of the present invention relate to circuit switching technology, in particular to an adapter and a method for using the same. Background technique [0002] With the rapid development of personal portable electronic devices, the two-wire power plug adapter has quickly occupied most application scenarios due to its advantages of small size and high cost performance. [0003] Two-wire power plug adapters can convert high-voltage (such as 220V) AC power to low-voltage (such as 5V) DC power needed to charge electronic devices. However, limited by the isolation conditions of the high-voltage and low-voltage terminals, it is impossible to completely eliminate the AC circuit path, so that there is a phenomenon that the high-voltage power-frequency AC is coupled to the low-voltage side along the primary and secondary paths of the transformer. Although the safety certification can ensure that the leakage current is within a safe range, but Due to th...

However, limited by the isolation conditions of the high-voltage and low-voltage terminals, it is impossible to completely eliminate the AC circuit path, so that there is a phenomenon that the high-voltage power-frequency AC is coupled to the low-voltage side along the primary and secondary paths of the transformer. Although the safety certification can ensure that the leakage current is within a safe range, but Due to the individual sensitivity differences of organisms such as people and pets, there may still be discomfort caused by induced currents
