Description

Card edge connector

This creation is about a card edge connector.

In a computer system, a card edge connector is used to plug an electronic card, such as a memory module. The card edge connector mainly inputs signals to the electronic card or outputs the signals of the electronic card to other components of the computer system. Therefore, the electronic card must be securely plugged into the card edge connector to allow the computer system to function properly. In addition, when an electronic card is inserted into the card edge connector from top to bottom, the card edge connector must also be able to tolerate multiple impacts and squeezing of the electronic card without deformation. However, conventional card edge connectors do not have the above characteristics. For example, Chinese Utility Model Patent No. CN96207543.4 (Recording of the Republic of China Application No. TW84212006; U.S. Patent No. 5,634,803) discloses a connector having a reinforcing wall structure, but the reinforcing wall and the tower portion and the elongated shape The body is integrally formed of plastic, and the rotation of the ejector device in use expands the two side walls of the tower portion, which easily breaks the reinforcing wall. Furthermore, the assembly process of the mounting ejector will also open the tower and have the opportunity to cause breakage of the reinforcing walls. Moreover, when the user inserts the card, the oblique force is inserted obliquely or the improper force in the lateral direction, and there is also an opportunity to cause the reinforcing wall to break. Moreover, the reinforcing wall is a vertical wall, and the corner of the lower edge of the electronic card hits the top end of the reinforcing wall when it is inserted.

According to the above problem, the present invention correspondingly proposes a card edge connector to solve the above problem.

An embodiment of the present invention provides a card edge connector. The card edge connector comprises an insulative body, a plurality of terminals and a metal reinforcement. The insulative housing includes a card slot and a tower portion. The tower portion has an inner direction toward the card slot, and an opposite direction to the inner side is an outer direction. The tower portion is included in the inner direction. Two opposite side walls. The plurality of terminals are arranged along the card slot. The metal reinforcement member is mounted between the two side walls of the tower portion, the metal reinforcement member includes a base portion, and the upper end of the base portion includes a guiding portion that is turned outward toward the outer side direction, and the guiding portion is inclined The lower direction extends toward the inner side.

The card edge connector provided by the embodiment of the present invention is connected between the two side walls of the tower by a metal reinforcement member, the metal reinforcement member can strengthen the strength between the two side walls of the tower portion to prevent the tower portion. In addition to the breakage of the connecting wall between the two side walls, an outwardly turned guiding portion of the metal reinforcing member can also guide the self-aligning insertion card slot of the electronic card and prevent the lower edge of the electronic card from being impacted. damaged.

The technical features and advantages of the present invention have been broadly summarized above, so that a detailed description of the present disclosure will be better understood. Other technical features and advantages of the subject matter of the patent application of this creation will be described below.
