地並排設置幾顆此種連接器以便於系統功能擴展。惟， 隨著電腦小型化之發展，主機.板上安裝更多電子元件’ 該電連接器之兩個頂出裝置於使用時會佔用較大空間， 為此業者有設計只採用一個頂出裝置之電連接器。 [0003] 與本創作相關之習知技術請參1997年8月26曰公告之美國 專利第5 ’ 660，552號，該習知技術揭示了 一種用以安裝 記憶體電子卡之插座連接器，該插座連接器包括一個設 有縱長形插槽之絕緣本體、於絕緣本體—端設置之頂出 裝置、及於絕緣本體另一端設置之彈性臂。該彈性臂由 絕緣本體一體成型並位於插槽之延伸方向上，彈性臂之 上端設置有一凸起。於記憶體電子卡裝入插槽時，記憶 體電子卡之縱向一端抵靠該凸起而使得彈性臂彈性變形 ’於記憶體電子卡向插槽深度方向移動至安裝位置時凸 起於彈性臂回彈力之作用下卡入記憶體電子卡一端之開 口内。由於彈性臂係由絕緣本體一體成型，該彈性臂強 度較弱因而容易損壞。 099103747 表單編號ΑΟίοι 第4頁/共33頁 0992007031-0 201128876 [0004] 與本創作相關之另一習知技術請參2008年l〇月29日公止 - 之令國大陸專利專利第201 142447號，該習知技術揭示 了另一種用以安裝記憶體電子卡之電連接器，該電連接 器包括：一絕緣本體，其沿縱向設有—可插接記憶體電 子卡之插槽’插槽兩側設有收容槽；多個導電端子’容 設於收容槽中；一頂出裝置，樞接於絕緣本體之—端， 且具有可卡扣於其中一開口之扣合部；以及一彈性體， 位於絕緣本體之另一端，其設有一主體部，該主體部一 ^ 端設有固定部，内側設有可卡扣於另一開口之卡持部， 該彈性體可沿絕緣本體縱向變形。於記憶體電子卡裝入 插槽時，記憶體電子卡之一側抵靠於彈性體並使其彈性 變形，並且記憶體電子卡之最初裝入位置與最終安裝位 置於縱向上有位移。於插裴過程中，彈性體會對記憶體 電子卡施加一個縱向之壓力，電子卡於用戶插裝力與彈 性體彈力之作用下，移動至最終安裝位置。由於於記憶 體電子卡插入電連接器過程中，彈性體對^子卡施加一 〇 個縱向上之力，該壓力會使得記憶體電子卡與絕緣本 體及導電端子之間沿縱向之摩擦加劇。 _5]疋以’有必要設計—種克服以上習知技術不足之電連接 器。

Description of the Invention: [Technical Field of the Invention] [0001] The present invention relates to an electrical connector, and more particularly to an electrical connector that can mount an electronic card and has an improved latching mechanism. [Previous technology] [〇〇〇2] At present, an electrical connector is commonly used in the industry to connect a memory electronic card to a computer motherboard. The insulative body of the electrical connector is provided with a slot for receiving a memory electronic card. Both ends of the insulating body are provided with a rotatable ejection device to facilitate the withdrawal of the memory electronic card. Usually, several such connectors are arranged side by side in a high density on the motherboard to facilitate system function expansion. However, with the development of computer miniaturization, more electronic components are mounted on the main board. The two ejector devices of the electrical connector take up a lot of space when used, and the manufacturer has designed to use only one ejector device. Electrical connector. [0003] A conventional technique related to the present invention is disclosed in U.S. Patent No. 5,660,552, issued on Aug. 26, 1997, which discloses a socket connector for mounting a memory electronic card. The socket connector comprises an insulating body provided with a longitudinal slot, an ejector device disposed at the end of the insulating body, and a resilient arm disposed at the other end of the insulating body. The elastic arm is integrally formed by the insulating body and is located in the extending direction of the slot, and the upper end of the elastic arm is provided with a protrusion. When the memory electronic card is loaded into the slot, the longitudinal end of the memory electronic card abuts against the protrusion to elastically deform the elastic arm. When the memory electronic card moves to the slot depth direction to the mounting position, it protrudes from the elastic arm. The elastic force is inserted into the opening of one end of the memory electronic card. Since the elastic arm is integrally formed by the insulative housing, the elastic arm is weak and thus easily damaged. 099103747 Form No. ΑΟίοι Page 4 of 33 0992007031-0 201128876 [0004] Another known technique related to this creation is to be referred to in 2008 on the 29th of January - the Continental Patent No. 201 142447 The prior art discloses another electrical connector for mounting a memory electronic card. The electrical connector includes: an insulative housing having a socket slot for inserting a memory electronic card in a longitudinal direction. a receiving slot is disposed on the two sides; a plurality of conductive terminals are received in the receiving slot; an ejector device is pivotally connected to the end of the insulating body, and has a fastening portion that can be snapped to one of the openings; and an elastic The body is located at the other end of the insulative housing, and is provided with a main body portion. The main body portion is provided with a fixing portion at one end, and a locking portion that can be buckled to the other opening is disposed on the inner side, and the elastic body can be longitudinally deformed along the insulating body. . When the memory electronic card is loaded into the slot, one side of the memory electronic card abuts against the elastic body and is elastically deformed, and the initial loading position of the memory electronic card and the final mounting position are displaced in the longitudinal direction. During the insertion process, the elastic body applies a longitudinal pressure to the memory electronic card, and the electronic card moves to the final installation position under the action of the user's insertion force and the elastic force of the elastic body. Since the elastomer applies a longitudinal force to the daughter card during insertion of the memory card into the electrical connector, the pressure causes the longitudinal friction between the memory card and the insulating body and the conductive terminals to be intensified. _5] 有 'necessary design — an electrical connector that overcomes the above-mentioned conventional techniques.
