Abstract

The invention discloses a mobile phone card holder capable of identifying three cards simultaneously. A rotating shaft, a first elastic sheet installation hole and a second elastic sheet installation hole are arranged on a protruding area of a fixing insulating plastic cement layer; a third elastic sheet installation hole is arranged on a recessed area of the fixing insulating plastic cement layer; a first Micro-SIM card contact elastic sheet, a TF card contact elastic sheet and a second Micro-SIM card contact elastic sheet are arranged in the first elastic sheet installation hole, the second elastic sheet installation hole and the third elastic sheet installation hole respectively; the top of the first Micro-SIM card contact elastic sheet and the top of the TF card contact elastic sheet are both arranged in a first card slot of a card support; the top of the second Micro-SIM card contact elastic sheet extends into a second card slot of the card support; a micro switch is arranged in the first card slot; and the micro switch and a limiting elastic sheet form a loop. The mobile phone card holder provided by the invention can identify three cards simultaneously, and therefore, the inner installation space of the mobile phone card holder can be fully utilized, and the overall thickness of the mobile phone card holder will not be increased.

Description

technical field [0001] The invention relates to the technical field of mobile phone card holders, in particular to a mobile phone card holder that can recognize three cards at the same time. [0002] Background technique [0003] With the continuous development of communication tools, the structure, style and performance of mobile phones are more and more frequent, and people's requirements for mobile phones are also getting higher and higher. For general mobile phone applications, most of the SIM (Subscriber Identity Module) cards are inserted into the card slot of the mobile phone, and after the activation procedure is completed, the mobile phone can be used to receive and make calls. Many existing mobile phones have dual-card dual-standby or dual-network dual-standby functions, that is, two SIM cards are installed in one mobile phone card holder, but due to the complicated circuit layout in the existing mobile phone card holder, the installation space is limited, Not...
