Description

electronic card connector

【Technical field】

The utility model relates to the electronic field, in particular to an electronic card connector for inserting electronic cards.

However, the SIM card holder connector is accompanied by an increase in the number of times of use, and the elastic arm is prone to permanent deformation due to frequent elastic deformation and thus cannot be reliably docked with the SIM card, and when the SIM card is released from the SIM card holder When withdrawing from the connector, the SIM card is likely to touch the free end of the elastic arm and cause the elastic arm to warp and deform, that is, a crack phenomenon occurs.

In addition, you can also refer to an improved card connector of the Chinese utility model patent CN203826604U announced on September 10, 2014, which can be installed on a circuit board and used to insert a micro SIM card. The card connector includes a shell A body assembly, a metal shell, and a contact fixed to the case assembly, the contact includes a frame body, a contact arm, and an extension. The contact arm has a free end on the inner side in the insertion direction, extends from the first side of the housing toward the inner side, is bent into, for example, a mountain shape, and is elastically deformed by being pressed by the inserted card. The extension part is folded back from the second side of the frame body and extends toward the first side, and the free end of the contact arm when the contact arm is deformed by being pressed by the card slides on the extension part.

However, if the SIM card is returned, the frame of the SIM card may withstand the end of the contact, so that the contact portion is retracted and deformed. In severe cases, the contact may be collapsed, affecting the service life of the card connector; The part is formed by bending downwards from the contact piece and extending in reverse. This structure may affect the short circuit between the contact piece and the circuit on the circuit board.

Therefore, there is a need for an electronic card connector related to practical requirements to meet market demands.
