Description

electronic card connector

本实用新型涉及一种电子卡连接器，具体地说，涉及一种具有侦测装置且用以电性连接电子卡和印刷线路板的电子卡连接器。The utility model relates to an electronic card connector, in particular to an electronic card connector which has a detection device and is used for electrically connecting an electronic card and a printed circuit board.

与本实用新型相关的现有技术可参照于1996年4月30日公告的美国专利第5,511,986号所示，其中该电子卡连接器具有用以侦测电子卡插入的侦测装置，而且侦测装置包括设在电子卡连接器侧壁上的一致动端子及一固定端子。当电子卡插入时，借电子卡的侧边抵持致动端子使其与固定端子接触。然而该电子卡连接器是以塑料本体作为侦测装置的支撑体，当在电子装置微型化的趋势下须缩小电子卡的体积时，用以容置侦测装置的塑料本体侧壁会变得太薄，这样不仅结构强度不足，而且成型的难度也会加大。The prior art related to the present utility model can be referred to as shown in U.S. Patent No. 5,511,986 announced on April 30, 1996, wherein the electronic card connector has a detection device for detecting the insertion of an electronic card, and the detection device It includes an activation terminal and a fixed terminal arranged on the side wall of the electronic card connector. When the electronic card is inserted, the actuating terminal is pressed against the actuating terminal by the side of the electronic card to make contact with the fixed terminal. However, the electronic card connector uses a plastic body as the support body of the detection device. When the electronic card needs to be reduced in size under the trend of miniaturization of electronic devices, the side wall of the plastic body for accommodating the detection device will become smaller. If it is too thin, not only the structural strength is insufficient, but also the difficulty of molding will increase.

另外，如于2000年3月21日公告的美国专利第6,039,599号所示，其揭示的是另外一种具有侦测装置的电子卡连接器，当电子卡插入时，借电子卡的底面抵持致动端子使其与固定端子接触，所以能相对减小电子卡连接器的宽度。但是，其致动端子与固定端子作动方式均为上下垂直作动，端子的位移量较大，容易引起塑性变形，而且这种安装方式不利于降低产品轮廓高度。In addition, as shown in US Patent No. 6,039,599 published on March 21, 2000, it discloses another electronic card connector with a detection device. When the electronic card is inserted, the bottom surface of the electronic card is used to resist The actuation terminal is brought into contact with the fixed terminal, so the width of the electronic card connector can be relatively reduced. However, the actuating terminal and the fixed terminal both move vertically up and down, and the displacement of the terminal is relatively large, which is easy to cause plastic deformation, and this installation method is not conducive to reducing the height of the product profile.

本实用新型目的在于克服上述缺陷，提供一种可利用产品轮廓高度而减少侦测装置所占空间，同时具有较高结构强度的电子卡连接器。The purpose of the utility model is to overcome the above-mentioned defects, and provide an electronic card connector that can reduce the space occupied by the detection device by utilizing the height of the product outline, and has a higher structural strength.

为实现上述目的，本实用新型包括绝缘本体、导电端子及侦测装置，其中绝缘本体一侧缘设有一开口，侦测装置安装于开口处，而且侦测装置包括致动端子和固定端子。当电子卡插入时，电子卡的底面抵持致动端子，使其与固定端子接触，其中致动端子的作动方式为沿电子卡的厚度方向作动，固定端子的作动方式为沿电子卡的宽度方向作动。另外，固定端子跨越绝缘本体开口两边，从而可以强化侦测装置与绝缘本体组装后的整体结构强度。To achieve the above object, the utility model includes an insulating body, a conductive terminal and a detection device, wherein an opening is provided on one side of the insulating body, and the detection device is installed in the opening, and the detection device includes an actuating terminal and a fixed terminal. When the electronic card is inserted, the bottom surface of the electronic card bears against the actuating terminal to make it contact with the fixed terminal. The actuating terminal operates along the thickness direction of the electronic card, and the fixed terminal operates along the electronic Action in the width direction of the card. In addition, the fixed terminals straddle both sides of the opening of the insulating body, so that the overall structural strength of the assembled detection device and the insulating body can be enhanced.

与现有技术相比较，本实用新型致动端子及固定端子的作动方式充分利用产品轮廓高度，从而减少侦测装置所占空间，同时固定端子跨越绝缘本体开口两边，使电子卡连接器具有较高结构强度。Compared with the prior art, the actuation mode of the actuating terminal and the fixed terminal of the utility model makes full use of the height of the product profile, thereby reducing the space occupied by the detection device, and at the same time, the fixed terminal spans both sides of the opening of the insulating body, so that the electronic card connector has High structural strength.
