Description

Electronic card connector

The invention relates to an electronic card connector, in particular to a noise-proof electronic card connector.

The conventional technology, referring to the Chinese utility model patent No. CN202111267, discloses a card connector, which includes an insulating body, a conductive terminal set housed in the insulating body, a shielding shell covering the insulating body, a tray and a Card withdrawal mechanism on one side of the insulating body. The insulating body and the shielding casing are enclosed to form a moving space for accommodating the tray. The shielding shell includes a main body portion and side walls formed by bending and extending from both sides of the main body portion. The side wall is provided with elastic pieces that can extend into the moving space, and the elastic pieces hold both sides of the tray. The card ejection mechanism includes a rotating piece and a push rod housed on one side of the moving space. With reference to Chinese Utility Model Patent No. CN200983414, a memory card connector is disclosed, which includes an insulating body, a conductive terminal set housed in the insulating body, and an upper cover pivotally fastened on the insulating body.

When the card is fully inserted, it is easy to shake and generate noise, which affects the user experience.

Therefore, it is necessary to improve the conventional electronic card connector to overcome the above-mentioned defects.

In view of the foregoing, an object of the present invention is to provide an electronic card connector that can reduce connector noise and prevent electrostatic damage.

In order to achieve the foregoing object, the object of the present invention is achieved by the following technical solutions: an electronic card connector, used in conjunction with an insert, including an insulating body, a terminal group held in the insulating body, and provided in the insulating A card ejection mechanism and a cover on one side of the body are provided on the insulating body and form a shielding housing of the receiving cavity. The card ejection mechanism includes a push rod and a cam. The front end of the shielding housing corresponds to the cam There is a limiting portion extending toward the receiving cavity, in the card-in state, the limiting portion bears against the front end surface of the cam, and applies a force to the cam backward, so that the cam is limited to the insertion Between the front end of the piece and the defined portion.

Compared with the conventional technology, the present invention has the following beneficial effects: the present invention adopts a shielding casing front end to provide an inwardly extending abutment portion to resist the front end of the pushing portion of the cam, so as to achieve the effect of fixing the cam to prevent noise from shaking, At the same time, the static electricity generated during the movement of the card withdrawal mechanism is derived.
