Abstract
The connector includes insulating body, mechanism for moving card back, and shield shell body. The mechanism for moving card back possesses sliding part, which is setup on the insulating body, and an elastic arm. The sliding part is possible to slide on the insulating body. One end of the elastic arm is fixed on the sliding part, and another end locks and holds the electric card. Bending part is setup between two ends of the elastic arm. A shield shell body covers the insulating body. Bending part of the elastic arm withstands the shield shell body. Thus, when locking and holding a card, elastic arm applies stronger force to the card. Thus, the card inserted is more stable.
