Thus, the features defined as "first" and "second" may explicitly or implicitly include at least one of these features.

Specifically, the electronic device 2000 may be any of various types of computer system devices that are mobile or portable and perform wireless communication (only one form is shown in FIG. 1 as an example). Specifically, the electronic device 2000 can be a mobile phone or smart phone (for example, based on iPhone TM, a phone based on Android TM), a portable game device (for example, Nintendo DS TM, PlayStation Portable TM, Gameboy Advance TM, iPhone TM), a laptop Computers, PDAs, portable Internet devices, music players and data storage devices, other handheld devices and such as headphones, etc., the electronic device 2000 can also be used for other wearable devices that need to be charged (for example, such as electronic bracelets, electronic Necklace, electronic device 2000 or smart watch head-mounted device (HMD)).

In the prior art, the charging assembly 100 may include wired charging and wireless charging. Wired charging is mostly contact charging, such as micro USB, lighting, and Type C. Contact charging usually requires a charging port with a metal tongue on the electronic device, and an external plug is inserted into the charging port and contacts the metal tongue to form an electronic device. to charge. However, there are the following problems in contact charging: First, the repeated plugging and pulling friction between the charging plug and the charging port will deform the charging port, thereby making the contact of the charging port loose and affecting the reliability of charging. Secondly, dust, water vapor, etc. have entered the charging port and adhered to the metal tongue. Corrosion of the metal tongue will increase the charging resistance of the charging port and increase the charging temperature. In severe cases, shell melting may even occur. Furthermore, if the external plug is pulled out during the charging of the electronic device, an arc will oxidize the metal tongue at the contact position of the charging port, which will increase the impedance and loss of the charging port, especially in the current low-voltage and high-current Direct charging has higher requirements on the overcurrent capacity of the charging path and the oxidation resistance and friction resistance of the conductive material.
