Embodiment 1
[0022] The embodiment of the present invention provides an interface connected with an external device, which is applied to an electronic device, such as figure 1 As shown, the interface includes:
[0023] Housing 1, an insertion space 2 is provided inside the housing 1 for inserting an earphone plug or a charging plug 11;
[0024] A plurality of contact shrapnels arranged in the insertion space 2; wherein,
[0025] When the earphone plug is inserted into the insertion space 2, some of the contact shrapnels are matched with the contact ends on the earphone plug in one-to-one correspondence for audio transmission;
[0026] When the charging plug 11 is inserted into the insertion space 2 , each contact shrapnel matches with the contact end on the charging plug 11 one by one for charging or data transmission.
[0027] Therefore, in the embodiment of the present invention, by improving the contact shrapnel disposed inside the insertion space 2 of the interface, the interface can...
Embodiment 2
[0041] The embodiment of the present invention provides a charging plug 11 applied to the above interface, such as figure 2 As shown, the charging plug 11 includes:
[0042] A cylindrical plug body, wherein a first data contact end 1101 , a second data contact end 1102 , an identification contact end 1103 , a ground wire contact end 1104 and a power contact end 1105 are arranged at intervals on the plug body.
[0043] Among them, the first data contact end 1101 is used to contact the first contact elastic piece 3 in the insertion space 2 of the interface; the second data contact end 1102 is used to contact the second contact elastic piece 4 in the insertion space 2 of the interface. Contact; the identification contact end 1103 is used to contact the third contact elastic piece 5 in the insertion space 2 of the interface; the ground wire contact end 1104 is used to contact the fourth contact elastic piece 6 in the insertion space 2 of the interface; The power contact end 1105...
Embodiment 3
[0046] An embodiment of the present invention provides an electronic device, including an interface connected to an external device as described above, a charging plug 11, and an earphone plug (not shown in the figure), wherein the charging plug 11 is used to cooperate with the interface. Wherein, the assembly diagram of the charging plug 11 and the interface is as follows: image 3 As shown, when the charging plug 11 is inserted into the insertion space 2 of the interface, the multiple contact ends on the charging plug 11 are respectively in contact with the multiple contact shrapnels in the insertion space 2, and then through the charging plug 11 and the The cooperation between the interfaces realizes the charging of the electronic equipment.
[0047] Since the interface is improved on the basis of the commonly used earphone jack, and the charging plug 11 is also improved on the basis of the commonly used earphone plug, the interface is suitable for both the commonly used ea...
