Description

Electronic card connector

The present invention relates to an electronic card connector, and more particularly to an electronic card connector having a function of avoiding terminal barb deformation and electronic card foolproof function.

With the rapid development of electronic technology, the use of electronic products such as digital cameras and digital cameras has become popular, and its functions and fields of use have also been increasing and expanding. At present, there are many types of electronic cards for these electronic products, such as SD. (Secure Digital Memory Card) card, MMC (Multi Media) card, Memory Stick PRO Duo card, Memory Stick PRO-HG Duo card, and SIM card for communication, etc., the above-mentioned electronic cards of different specifications have been widely used in electronic products. .

Since the development of electronic cards is in line with the trend of easy to use and carry electronic products, the volume is shrinking and the transmission speed is also increasing. In order to correspond to each other and achieve electrical connection, many different electronic card connectors need to be designed. Plug in.

At present, the conventional electronic card connector is provided with a plurality of contact terminals on the body, the contact terminals are fixed on the body, one end of which is a telecommunication contact end, and the other end is a soldering end; and the body is covered with a metal cover body. The body is provided with a sliding mechanism, which can provide the function of elastic positioning and elastic release after the electronic card is inserted through the sliding mechanism. When the electronic card is inserted, the sliding mechanism elastically positions the electronic card and is electrically connected with the contact terminal. And the user wants to take out the electronics When the card is stuck, the electronic card is elastically taken out through the sliding mechanism.

Although the structure of the electronic card connector can provide the functions of providing electronic card insertion and electrical contact, the volume of the electronic card is less likely to be lighter and thinner as the size of the electronic device is reduced. Therefore, the user is not easy to judge. And to determine whether the direction of the electronic card is correctly inserted. If the user inserts the electronic card into the electronic card connector by using the wrong angle, the electronic card connector may be damaged in addition to the purpose of not being able to reach the electrical connection. Even worse, the electronic card may not be removed and the electronic device may be damaged.

In addition, since the electronic card connector provides a single electronic card electrical connection contact, the electronic card having a smaller volume and a thinner thickness is placed on the tray and contacts the contact terminals of the electronic card connector to provide the same. For the purpose of using electronic cards of different specifications, however, when the electronic card of the tray is used for card withdrawal, it often happens that the tray pulls the contact terminal toward the outside and the contact terminal is deformed, thereby causing damage to the electronic card connector.

It can be seen that there are still many shortcomings in the above-mentioned conventional electronic card connector, which is not a good designer, and needs to be improved.

In view of the shortcomings derived from the above-mentioned conventional electronic card connectors, the creators of this case have improved and innovated, and after years of painstaking research, they finally successfully developed and completed the electronic card connector.

The purpose of the present invention is to provide an electronic card connector that can prevent the electronic card from being deformed by reversing the terminal when the card is ejected.

Another object of the present invention is to provide a positioning portion extending through the base to provide an electronic card connector having an electronic card foolproof function.

In order to achieve the above object, the present invention comprises an insulative body; a plurality of conductive terminals fixed to the bottom of the insulative housing and extending upward from the bottom of the insulative housing; a sliding mechanism disposed on the side of the insulative housing The edge of the conductive terminal is provided with the elastic reciprocating action; a metal cover is attached to the insulating body; wherein the front end of the conductive terminal respectively has a first contact portion and a second contact portion, when the electronic card is inserted The first contact portion can be pressed toward the bottom surface of the insulating body, and the second contact portion is simultaneously displaced toward the insulating bottom surface, thereby preventing the electronic contact card from pulling the second contact portion outward from the insulating body when the card is retracted. Deformation.

In order to achieve the other purpose of the present invention, the base is bent toward the electronic card accommodating space of the insulative housing to extend a positioning portion for limiting the width of the end of the electronic card accommodating space, so when the electronic card When inserted in the reverse direction, the positioning portion can offset the inserted electronic card to the limit position, thereby preventing the reverse inserted electronic card from forcibly entering the electronic card connector, thereby effectively preventing the electronic card from being damaged due to incorrect insertion. This creation has another purpose of the electronic card foolproof function.
