本論文主要在改善智慧卡連接器使用時智慧卡行程過短與操作不便的問題，並且避免模組尺寸過大。本論文首先分析現有各類型智慧卡連接器設計原理與優缺點，再評估各類型機構，以選定適合機構以設計新式智慧卡連接器。接著將智慧卡移動以方程式表示，以便確認各零件在操作中的相對間隙與干涉狀況，並增加安全間隙以避免干涉。接著以SolidWorks繪製新式設計的3D模型並進行運動分析，以評估並排除在實際操作中可能產生的問題與缺陷。最後製作原型，並量測安裝與取出智慧卡時所需的外力，以及取出智慧卡時智慧卡的實際移動量。研究最終確認取出智慧卡時需要外力12.6 N，且可使SIM卡退出5.71 mm優於現行產品，這表示新式連接器有助消費者拔出智慧卡。

The objective of this thesis was to resolve the two problems, short stroke and inconvenient operation, associated with the current SIM card connector, and the solution cannot be oversized. First, we analyzed five major types of the SIM card connectors that were on the market and discussed their advantages and disadvantages. Next, we evaluated several four-bar linkages to determine the suitable mechanism for developing the SIM card connector in this thesis. We represented the movement of the SIM card by equations to make it easy to check the gaps and avoid the interferences between the SIM card and the mechanism. Then we used the CAD software SolidWorks to perform the kinematic analysis so as to predict the possible problems during the operation of our SIM card connector. Finally, we made a prototype of the SIM card connector to allow us to perform the measurement kinetically and kinematically. The push-out force for our connector was 12.6 N, and the movement when the SIM card was pushed out was 5.71 mm. The results are better than existing products, which means that the new SIM connector developed in the thesis can help users access the SIM card.
