technical field

The utility model relates to an electric connector, in particular to a locking mechanism of an electronic card connector.

Background technique

With the rapid development of electronic products such as mobile phones and digital cameras, the memory for storage of such electronic products is generally slightly insufficient. Therefore, electronic manufacturers add electronic card connectors in electronic products to connect external memory card media, so as to expand the storage capacity of electronic products. The signal connection between the electronic card and the printed circuit board in the electronic product is realized by means of the electronic card connector installed on the electronic product.

The existing electronic card connector, as disclosed in Taiwan Utility Model Patent M308536, mainly includes an insulating body, more than two conductive terminals accommodated in the insulating body, a card ejection mechanism and a shielding shell. The card ejection mechanism includes a slider with a heart-shaped chute, a push rod and a spring, and one end of the slider is assembled with a metal buckle arm; one end of the push rod is buckled with the side wall of the insulating body, and the other end is installed In the heart-shaped chute; the spring is arranged between the slider and the rear wall of the insulating body.

In use, when the electronic card is not inserted, the buckle arm is accommodated in the corresponding through groove formed by the insulating body; when the electronic card is inserted into the electronic card connector, the electronic card forces the slider to move forward, thereby driving the buckle arm to disengage The through groove protrudes into the card receiving space, and then cooperates with the notch of the electronic card to apply further thrust. When one end of the push rod is buckled with the notch of the heart-shaped chute, the electronic card is fixed on the card connector. middle. Push the electronic card again along the insertion direction when taking out the card, and the slider and the electronic card are driven to pop up along the pulling out direction by the elastic force of the spring, so that the electronic card can be taken out from the electronic card connector.

In order to achieve the purpose of card locking, a buckle arm is installed on the side of the slider of the card ejection mechanism of the electronic card connector to cooperate with the notch on the electronic card to buckle, thus increasing the assembly process and indirectly increasing the manufacturing cost. In addition, when the electronic card is inserted and withdrawn for many times, the buckle arm will be excessively deformed, which will affect the locking and positioning function of the locking member and the notch of the electronic card, and affect the normal use of the card ejecting mechanism.

Pull it out to improve the stability of signal transmission.

In order to achieve the above object, the utility model provides a card locking mechanism of an electronic card connector, the connector includes an insulating body, more than two conductive terminals and a card ejecting mechanism, and the insulating body has a plugging space for the electronic card to be inserted into , the card ejecting mechanism includes a slider, the card locking mechanism includes a locking arm and a guide groove, the locking arm is integrally formed on the sliding block, the free end of the locking arm has a hook and a The protruding limit block; the guide groove is provided on the side of the insertion space of the insulating body, the guide groove has a wide mouth section and a narrow mouth section connected to the wide mouth section, the wide mouth section and the narrow mouth section For the limit block to guide the limit inside.

Further, the guide groove is a blind groove.

Further, the limiting block is located on the end surface behind the hook.

Further, the lateral width of the wide-mouth section is greater than the lateral width of the narrow-mouth section.

Further, the wide-mouth section is located in front of the narrow-mouth section and is formed at an outer position.

Compared with the prior art, the utility model has the following effects: by integrally forming the locking arm on the slider, the locking mechanism can not only save component costs, but also greatly save manufacturing cost. The limit block is formed under the free end of the locking arm, so that the longitudinal thickness of the connector is thinned. At the same time, the card locking mechanism prevents the electronic card from being pulled out directly from the insertion space, thereby improving the stability of signal transmission.
