Electronic card connector

The present invention relates to a connector, and more particularly to an electronic card connector.

The card connector is one of the indispensable components in the mobile phone. The trend of the conventional card connector to be thinner with the mobile phone product is getting thinner and thinner, but the insulation after the plastic injection molding is bound to have a warp phenomenon, and then In addition, the center of gravity of the card connector is concentrated on the side of the card ejecting mechanism, which causes a lever effect to make the other side lift more, so that the other side has an empty welding process between the board and the circuit board. .

Referring to the Chinese Utility Model No. CN201478524U, an electrical connector is disclosed, which is intended to solve the problem of the occurrence of air welding in the process of the card connector. The electrical connector includes at least a body and a plurality of conductive terminals received in the body. The body includes at least an abutting surface and a mounting surface. The conductive terminal includes at least a base, an elastic portion connected to the base and protruding from the body, and a tail portion protruding outside the body. The vertical distance between the upper surface of the base of the conductive terminal in the middle of the body and the lower surface of the tail is different from the vertical distance between the upper surface of the base of the conductive terminal at the end of the body and the lower surface of the tail. The electrical connector reduces the gap between the lower surface of each of the conductive terminals by adjusting the vertical distance between the upper surface of the base of the plurality of conductive terminals and the lower surface of the tail during the manufacturing process. However, in the process of the electrical connector, the warpage of each body is different, so that the process of aligning the lower surface of the tail of each conductive terminal is difficult to control, if different bases are calculated according to the warpage amplitude of each body. The vertical distance from the upper surface to the lower surface of the tail affects production efficiency and increases process costs.

Therefore, it is indeed necessary to provide a new electronic card connector to overcome the aforementioned drawbacks.

The purpose of the present invention is to provide an electronic card connector which is convenient in manufacturing process and can effectively reduce the warpage of the product and avoid the occurrence of air welding.

The present invention provides an electronic card connector including an insulative housing, a plurality of conductive terminals held on the insulative housing, a shielding housing forming a receiving cavity with the insulative housing, a card ejecting mechanism, and a reinforcing member. "H"-shaped, the reinforcing member includes a supporting portion on a side close to the card ejecting mechanism, a fixing portion corresponding to the other side of the supporting portion, and a connecting portion connecting the supporting portion and the fixing portion, the support The bottom portion defines a bottom end surface and a bottom end surface corresponding to the top end surface, and the top end surface of the support portion is stamped and formed with a groove, the bottom surface of the groove protrudes downwardly from the bottom end surface, and the insulating body and the reinforcing member are integrally formed .

Further, the groove is formed by punching a recess from the top end toward the bottom end surface.

Further, the reinforcing member is partially exposed to the insulating body.

Further, the groove is exposed to the insulating body.

Further, the grooves are one or plural.

Further, the plurality of grooves are linearly distributed on the support portion along a direction perpendicular to the extending direction of the connecting portion.

Further, the reinforcing member is made of metal.

Compared with the prior art, the present invention has the following effects: the electronic card connector of the present invention can effectively reduce the insulating body by forming a binding force on the insulating body by integrally forming the insulating body and the reinforcing member. The amplitude of the warp of the self; further, since the support portion of the reinforcing member is provided with a groove, the bottom surface of the groove protrudes downwardly from the bottom end surface, and the bottom of the groove abuts the circuit board to the top of the electronic card connector body As a result, the effect of the leverage effect caused by the focus of the main body on the side of the card ejecting mechanism is eliminated, thereby reducing the warpage of the product and avoiding the air welding phenomenon on the other side corresponding to the card ejecting mechanism.
