Card holder mounting structure with good protection performance for mobile terminal

Abstract

The invention relates to the technical field of mobile terminal equipment, and particularly relates to a card holder mounting structure with good protection performance for a mobile terminal. The cardholder mounting structure comprises a connecting seat arranged in the mobile terminal, wherein a mounting groove is formed in the top surface of the connecting seat, a placement groove is formed in the front side of the bottom surface of the mounting groove, guide grooves are formed in the left and right sides of the mounting groove, a sealing groove is formed in the front end of the guide groove, a lap joint groove is formed in the rear side of the right end of the sealing groove, a spring A is connected to the middle of the inner wall of the rear end of the mounting groove, a card holder assembly is arranged in the connecting seat, an auxiliary dismounting assembly is arranged on the right side in the card holder assembly, and a fixing assembly is further arranged in the mounting groove. Compared with an existing SIM card mounting structure, the card holder mounting structure has the advantages that the card holder can be directly taken out without the help of an external pin inserting tool, an inserting hole does not need to be formed in the outer wall of the mobile terminal, the sealing performance of the mobile terminal can be improved, the use scene of the mobile terminal isexpanded, and meanwhile, the SIM card is convenient to replace.

Description

technical field [0001] The invention relates to the technical field of mobile terminal equipment, in particular to a card holder installation structure with good protection performance for a mobile terminal. Background technique [0002] The SIM card is the IC card held by the mobile user of the GSM system, called the subscriber identification card. The GSM system identifies the GSM user through the SIM card. The same SIM card can be used on different mobile phones. The GSM mobile phone can only be used after inserting the SIM card. The SIM card is the key for the GSM mobile phone to connect to the GSM network. Once the SIM card is pulled out from the mobile phone, the mobile phone will not be able to enjoy various services provided by the network operator except for emergency calls. The SIM card can be used as a key. , It also provides users with a lot of convenience. Users only need to insert or embed the SIM card into any GSM terminal to realize communication. The inform...

Problems solved by technology

[0003] The purpose of the present invention is to provide a card holder installation structure with good protective performance for a mobile terminal, to solve the existing SIM card proposed in the above-mentioned background technology. Corresponding card slots are provided on the mobile terminal to provide installation space. For the convenience of installation and disassembly, pinholes are reserved, and the impact is that the waterproof performance of the mobile terminal device is greatly affected, thus limiting the use of the device. At the same time, when the existing SIM card is installed, it needs to be taken out with the help of external pins, and the operation process is relatively cumbersome.
