Problems solved by technology

Especially mobile phones, almost everyone has one. When there are many family members, the adapters may be randomly placed. If the appearance of the respective adapters is relatively different, it is relatively easy to identify. For those adapters with small appearance differences, It is more difficult to distinguish. Mixing adapters may not only affect the charging speed, but also affect the service life of the battery and adapter, and sometimes even lead to accidents.
[0003] The application number is: 200610063083.4 The disclosed control circuit and method for identifying the power adapter provides a solution to the above problems. The solution uses a voltage control switch to control the on-off of the charging circuit, and stops when the power adapter is a non-original adapter. Charging, this solution ignores the user experience. Many times, some electronic products we buy are only equipped with usb cables, without adapters. Occasionally, we still need to use adapters from other devices. At this time, as long as the charging safety can be guaranteed

Embodiment 1

[0023] Figure 1-2 The schematic block diagram of the adapter circuit and the circuit diagram of the adapter provided in this embodiment only show the parts related to the embodiment of the present invention for the convenience of description.

[0024] This embodiment provides a power adapter, the power adapter and the matching electrical connector can communicate, send a feedback signal to the electrical connector, and then confirm whether the current adapter is charging the compatible device, That is: whether the adapter is the original adapter of the device, in this way to avoid mixed use of adapters, protect the adapter and battery and ensure the efficiency of charging.

[0025] Please refer to figure 1 , figure 1 It is a circuit block diagram of the adapter, the adapter includes the adapter mcu1, the adapter mcu1 is connected with the signal receiver 2, the signal receiver 2 receives the indication signal from the electrical connector of the matched device, and sends th...

Embodiment 2

[0039] Figure 3-4 This embodiment provides an electrical connector matched with the power adapter provided in the first embodiment.

[0040] Please refer to image 3 , image 3 It is a schematic block diagram of the electrical connector circuit of the present invention. An electrical connector includes an electrical connection end 13. The input end of the electrical connection end 13 is connected to the output end of the adapter basic circuit 4 when in use, and the output end of the electrical connection end 13 is connected to the electrical connection end. The connector mcu8 and the electrical connector mcu8 are connected with a signal sending module 9, and the electrical connector mcu8 sends an indication signal to the adapter mcu1 through the signal sending module 9, and the adapter mcu1 only receives the indication signal sent by the matching electrical connector Only then will the feedback unit 3 be driven to send a feedback signal, and the electrical connector mcu8 is...

Abstract

The invention discloses a power adapter, which includes a voltage transforming circuit and a rectifying circuit, and is characterized in that: it also includes a signal receiver, the signal receiver receives an indication signal from a matching electrical connector, and transmits the indication signal Send to the adapter MCU; the adapter MCU controls the feedback unit to send the feedback signal to the electrical connector; the electrical connector confirms that the power adapter is the original power adapter after receiving the feedback signal. The invention provides an adapter. When the electrical connector is in use, it sends an indication signal to the adapter. The adapter receives the signal and sends a feedback signal. After receiving the feedback signal, the electrical connector confirms that the adapter is the original adapter, avoiding the adapter mixed. In the present invention, the feedback signal is a sound signal, and the sound signal can not only help the electrical connector identify the identity of the adapter, but also more directly prompt the user that the adapter is an original adapter.

Description

technical field [0001] The invention relates to the technical field of charging, in particular to a power adapter and an electrical connector thereof. Background technique [0002] With the progress and development of society, more and more electronic products have entered people's daily life, such as e-book readers, tablet computers, reading pens, mobile phones and so on. Especially mobile phones, almost everyone has one. When there are many family members, the adapters may be randomly placed. If the appearance of the respective adapters is relatively different, it is relatively easy to identify. For those adapters with small appearance differences, It is more difficult to distinguish. Mixing adapters may not only affect the charging speed, but also affect the service life of the battery and adapter, and sometimes even lead to accidents. [0003] The application number is: 200610063083.4 The disclosed control circuit and method for identifying the power adapter provides a ...
