Foolproof mechanism for mobile phone, external device and plug mechanism thereof, and mobile phone

Abstract

The invention discloses a foolproof mechanism for a mobile phone, an external device and a plug mechanism thereof, and the mobile phone. The foolproof mechanism comprises a first shell and a second shell, wherein the first shell and the second shell are plugged together for connecting external equipment through communication; the first shell is arranged in the mobile phone; a flat cavity is form at the front end of the first shell in an enclosing way; at least one end on the side of the bottom of the flat cavity is provided with a hook in an extending mode; the second shell is provided with a groove in fit with the hook; at least one position on the top of the flat cavity bends inwards to form a protrusion; the second shell is provided with a groove in fit with the protrusion; and the foolproof mechanism is respectively arranged on the external device, the plug mechanism and the mobile phone. The foolproof mechanism completely eliminates error plug of the external device of the mobile phone, reduces error rate in connecting the external equipment to the mobile phone, and improves stability and security of data transfer by the mobile phone.

Description

technical field [0001] The invention relates to a fool-proof structure of an external device, in particular to a fool-proof mechanism for a mobile phone, an external device, a plug mechanism and a mobile phone. Background technique [0002] At present, mobile phones have more and more functions, such as Internet access, Bluetooth or infrared transmission functions, and keyboard input functions, which greatly facilitate the user's operation. However, with the further development of technology, people put forward higher requirements for the functions of mobile phones, and the connection and splitting operations between mobile phones and external devices are becoming more and more frequent. If the plug-in device is connected incorrectly, it will easily cause damage to the mobile phone and external devices. But in the prior art, the fool-proof structure of the external socket of the mobile phone generally adopts a push-button type, but the push-button type fool-proof structure i...

However, with the further development of technology, people put forward higher requirements for the functions of mobile phones, and the connection and splitting operations between mobile phones and external devices are becoming more and more frequent. If the plug-in device is connected incorrectly, it will easily cause damage to the mobile phone and external devices. However, in the prior art, the fool-proof structure of the external socket of the mobile phone generally adopts a push-button type, but the push-button type fool-proof structure is easy to cause damage to the socket, and the stability of this kind of fool-proof structure is relatively poor
