Description

  The present invention relates to a card connector device, and more particularly to a card connector device for electrically connecting a card to a circuit board.

The prior art is a card connector device as disclosed in the prior art document, and includes a base body, a conductive terminal attached to the base body, and a discharge mechanism attached to the base body to discharge the card. In addition, an insertion space for accommodating a card is defined in the base body.

The slide member and the propulsion unit are integrally formed (for example, see Patent Document 1).
Taiwan Utility Model Notification No. 575237

  When the card is inserted into the insertion space of the base body, when the card abuts on the propulsion part and presses the propulsion part, the card insertion force causes the slide member to move in the card insertion direction with respect to the base body. The spring member is compressed and elastically deformed to have a restoring force. When the card is ejected, when the card is pressed again with a finger, the slide member is slid in the card ejection direction with respect to the base body by the restoring force of the spring member, and further, the propulsion is formed integrally with the slide member. The card is discharged from the insertion space of the base body by the portion.

  The propulsion unit formed integrally with the slide member of the card connector device disclosed in Patent Document 1 receives the card insertion force to slide the slide member relative to the base body and compress the spring member. Therefore, when the card insertion force increases, the propulsion unit may be broken or torn from the slide member. In order to solve the above problems in the industry, by increasing the thickness of the propulsion unit and increasing the thickness of the connecting portion between the propulsion unit and the slide member, the structural strength and the connection strength of the propulsion unit are increased. Increase. However, the dimensions of the propulsion unit are also increased, which is disadvantageous for the development toward miniaturization of the card connector device. Therefore, it is necessary to develop a card connector device that improves the shortage of conventional techniques.
