Description

Subscriber Identification Card Connector with Ejection Mechanism

Technical field

The utility model relates to a subscriber identification (Subscriber Identity Module, SIM) card connector that can be configured on a mobile phone, in particular to a subscriber identification card connector that can be configured on a mobile phone and has a card return mechanism.

Background technique

In a general digital mobile phone system, a mobile phone number usually corresponds to a SIM card, and only when a mobile phone user obtains a SIM card and uses it with his mobile phone can the system identify each user, which is called a SIM card. The corresponding user provides services such as calls, and serves as the basis for calls and billing. In addition, SIM card is also a kind of micro-processing chip, and its storage space can store relevant identification data used by users in communication for memo, such as personal phone book, mobile phone number, communication parameters, etc. The cooperation between the SIM card and the mobile phone is to install a subscriber identification card connector electrically connected to the circuit board of the mobile phone in the mobile phone, and the SIM card can be detachably inserted into the subscriber identification card connector and electrically connected with it.

The existing subscriber identification card connector generally presses a shrapnel on the SIM card so that the SIM card is fixed therein. When the SIM card needs to be extracted, the shrapnel is opened and then pulled out or pushed out with fingers. However, because the SIM card and the subscriber identification card connector occupy very little hardware space in the mobile phone, it is difficult for the user to apply force directly on the surface of the SIM card to push the SIM card. , will scratch and damage the SIM card, affecting the function of the SIM card. In addition, the surface of the SIM card is usually smooth. If the user's finger is wet and exerts force on the surface of the SIM card, the user cannot push the SIM card due to insufficient friction. At this time, other assistance must be used. Only tools can be used to remove the SIM card, which is quite troublesome and time-consuming.

Therefore, there is a great need for a SIM card connector that is convenient for taking out the SIM, so as to improve many deficiencies in the prior art.
