AI Technical Summary

Benefits of technology

The design effectively prevents card ejection during use, maintaining a stable connection and preventing data loss by locking the sliding body with the elastic slice, thus ensuring continuous communication between the card and circuit board.

Problems solved by technology

However, in use, if the card is accidentally pushed inward by an external force, the card connector easily springs the card out through the released power from the spring.
As a result, the communication of the card and the circuit board is undeservedly interrupted and the data which is being transmitted is easily lost.

Embodiment Construction

[0017]Referring to FIGS. 1-6, a card connector 100 according to an embodiment of the present invention is adapted for receiving an external card (not shown). The card connector 100 includes an insulating housing 10, a plurality of terminals 20, an ejecting device 40 and a cover 30.

[0018]The insulating housing 10 defines a receiving chamber 11 for receiving the card therein, and a sliding recess 12 adjacent to one side of the receiving chamber 11. A top of a side wall 14 of the insulating housing 10 beside the sliding recess 12 defines a gap 141. The terminals 20 are disposed in the insulating housing 10 and project upward into the receiving chamber 11 for electrically connecting the card. The ejecting device 40 includes a sliding body 41 slidably disposed in the sliding recess 12 of the insulating housing 10, a spring 42 restrained between a rear sidewall of the sliding recess 12 and the sliding body 41, and an ejecting pin 43. A pushing arm 411 is formed at a rear end of the slidin...

Abstract

A card connector includes an insulating housing defining a receiving chamber for receiving a card, a plurality of terminals disposed in the insulating housing, an ejecting device disposed in one side of the receiving chamber, and a cover coupled on the insulating housing. The ejecting device includes a sliding body of which a top defines a sliding fillister, and a spring restrained between a rear sidewall of the receiving chamber and the sliding body. A bottom sidewall of the sliding fillister protrudes upward to form a blocking block designating a front face thereof as a blocking face. The cover has a top plate of which one side is die-cut to form an elastic slice inclined downward into the sliding fillister. The elastic slice resists against the blocking face in use to keep the sliding body being locked, and sets free the blocking block when ejecting the card out.

Description

BACKGROUND OF THE INVENTION[0001]1. Field of the Invention[0002]The present invention generally relates to a card connector for receiving a card therein, and more particularly to a card connector capable of preventing the card from being ejected out in use.[0003]2. The Related Art[0004]Traditionally, a card connector adapted for being soldered on a circuit board and receiving a card therein has an ejecting device used for withdrawing the card from the card connector. The ejecting device includes a sliding body, a spring and a connecting bar. While the card is inserted into the card connector, the card pushes the sliding body to move. Then the spring is compressed and the connecting bar jostles the sliding body to keep the sliding body and the spring relatively immovable. While the card will be withdrawn from the card connector, the card is again pushed inward to make the sliding body discharged from the connecting bar. And the power stored in the spring is released so as to drive th...
