pc卡為一種用以給電腦及其它通訊和電子設備添加諸如記憶 體、網路及無線通訊等擴展裝置之電子卡，幾乎所有筆記型電腦側 邊均設有PC卡插槽以用於延伸記憶體或網路等週邊功能。PCMCIA (Personal Computer Memory Card International Association-個人電A PC card is an electronic card used to add expansion devices such as memory, networking, and wireless communications to computers and other communication and electronic devices. Nearly all notebook computers have PC card slots on the sides for extended memory. Peripheral functions such as body or network. PCMCIA (Personal Computer Memory Card International Association-Personal
腦存儲卡國際協會）於2003底再一次公佈了 pc卡之一種新標準， 即Express Card。這種Express Card標準的PC卡有兩種外型，一 種為L形，另一種為矩形，矩形Pc卡的寬度與l形PC卡的最小 寬度相同。而用於Express Card標準的電子卡連接器也有L形和矩 形兩種。L形的電子卡連接器可與兩種卡中任意一種配接，而矩形 電子卡連接器只能與矩形的PC卡配接。 中華民國新型專利第253081號揭示一種用於Express Card的 電子卡連接器，其可收容L形和矩形兩種Express Card。參見該專 利第二圖和第三圖，該電子卡連接器之遮蔽殼體3〇前緣向下彎折 形成一前擋部32，該前擋部32遮蓋在絕緣本體1〇的前緣，位於 導電端子20的上方並和導電端子2〇之間有一定的間隙。當插入電 子卡時，導電端子2〇隨絕緣本體1〇 一同向前作一較小的移動，並 接近於雨擋部32。此外，前擋部32可能受其它外力作用而被下壓 並接近於導電端子20，如果該等額外因素超過電子卡連接器所能 承受之範圍，則有可能使得遮蔽殼體與導電端子接觸，由於遮蔽殼 體通常為金屬製成，故有可能造成端子間的短路。 因此’確有必要對現有之電子卡連接器進行改進以克服現有技 術之缺陷。 【新型内容】 蓉於上述狀況，本創作之目的係提供一種可有效防土端子短路 之電子卡連接器。 本創作之目的係通過以下技術方案實現的：一種電子卡連接 6 M307886 器，其包括：絕緣本體、收容於絕緣本體内的導電端子及覆蓋 於絕緣本體上的遮蔽殼體，所述絕緣本體包括有基部，於基部 前緣設有一阻隔部，於所述阻隔部下方設有一抵持部其可防止 遮蔽殼體與導電端子的接觸。 相較於先前技術，本創作之電子卡連接器於絕緣本體前緣設置 一凸出的阻隔部，該阻隔部可將遮蔽殼體和導電端子有效分開，從 而防止端子短路。 【實施方式】At the end of 2003, the Brain Memory Card International Association announced a new standard for PC cards, the Express Card. This Express Card standard PC card has two appearances, one is L-shaped and the other is rectangular. The width of the rectangular Pc card is the same as the minimum width of the l-shaped PC card. The electronic card connector for the Express Card standard is also available in both L-shape and rectangular shape. The L-shaped electronic card connector can be mated to either of the two types of cards, and the rectangular electronic card connector can only be mated with a rectangular PC card. The Republic of China New Patent No. 253,081 discloses an electronic card connector for an Express Card that can accommodate both an L-shaped and a rectangular Express Card. Referring to the second and third figures of the patent, the front edge of the shielding case 3 of the electronic card connector is bent downward to form a front stop portion 32, and the front stop portion 32 covers the front edge of the insulating body 1〇. There is a certain gap between the conductive terminal 20 and the conductive terminal 2〇. When the electronic card is inserted, the conductive terminal 2 is moved forward along with the insulating body 1〇 and is close to the damper 32. In addition, the front stop portion 32 may be pressed down by the external force and close to the conductive terminal 20. If the additional factor exceeds the range that the electronic card connector can withstand, it is possible to make the shield case contact the conductive terminal. Since the shield case is usually made of metal, it may cause a short circuit between the terminals. Therefore, it is indeed necessary to improve existing electronic card connectors to overcome the deficiencies of the prior art. [New Content] In the above situation, the purpose of this creation is to provide an electronic card connector that can effectively prevent short circuit of the earth terminal. The purpose of the present invention is achieved by the following technical solution: an electronic card connection 6 M307886, comprising: an insulative housing, a conductive terminal received in the insulative housing, and a shielding housing covering the insulative housing, the insulative housing includes The base portion has a blocking portion at the front edge of the base, and a resisting portion is disposed under the blocking portion to prevent contact between the shielding case and the conductive terminal. Compared with the prior art, the electronic card connector of the present invention is provided with a protruding blocking portion at the front edge of the insulating body, which can effectively separate the shielding case and the conductive terminals, thereby preventing the terminals from being short-circuited.
