本研究主要探討插座彈片之干涉變形量(撓度)與插銷之拔出力之關係，將所得之數據進行歸納及模組化，最終所得之結果可提供插座設計者以較低之成本及模組化方式進行插座之設計，且其適用之範圍可涵蓋世界各國之插座95% 以上。所選之彈片材質為厚度0.6t之黃銅，是極為普遍通用之素材，其價格低廉且物理性質穩定。本文所探討之設計分析模組將包覆彈片之塑膠件與電子構裝產品之機殼結合為一，較一般市面上所售之插座節省不少材料零件成本。
世界各國之插座彈片設計方式難以計數，雖插頭之插銷尺寸無法統一，但型態不是圓形就是扁平狀。本研究將設計一組插座結構供圓形插銷及扁平狀插銷使用，並將各設計尺寸設為定值，僅以插銷插入彈片後之干涉變形量為可控制之參數。
本研究之進行步驟，首先，以有限元素分析軟體計算出干涉變形量由小遞增所造成的力變化。此產生之力為彈片夾持插銷之反作用力，而拔出插銷所需之力可由此反作用力及摩擦係數推算出。世界各國對於插座彈片之拔出力皆有一定規範，其為插座設計之重要驗證項目。
其次，歸納出插銷插入彈片後之干涉變形量與插頭拔出力之關係，並將其對應關係建立資料庫，而設計者只需輸入所需之拔出力及插銷厚度或直徑，程式即可從資料庫找出彈片尾部雙翼之間的間隔尺寸。最後以美國及中國插座為例，以本文所建立之資料庫進行插座設計，並實際開模製出樣品，驗證實際插銷之插銷拔出力之量測值與資料庫之計算值之差異，結果顯示兩者間之差異值在可容許之範圍，證明本文所建立之插銷設計模式之實用性。

The main purpose of this study is to discuss the relationship between deflection of spring bussbar and retention force of plug pin. The data obtained are analyzed and modulized .The solution of result can provide socket designer to proceed 95 % worldwide types of socket design with low cost and modular way .
The selected raw material is braze with 0.6mm thickness , it is a general material with cheap and stable characteristics , The design & analytic module discussed in this study will combine housing of spring and main enclosure together which can save much cost of parts compared to the conventional inserted socket .
There are numerous of methods for universal socket design . Although dimensions of plug pin are different , but only owns flatted or tabular shape . This study will design a model of spring bussbar for the two plug pins . Only the deflection of spring after insertion is considered as a variable factor . Firstly , using software of CAE to calculate the changes of force caused by the increasing of deformation. The retention force between spring and plug pin and the force of pulling socket out can be calculated by . All countries around the world have their own standard for socket retention force which is an important testing item of socket design.
Furthermore , we will observe the relationship between data of defection after plug inserted and force of plug pin pulling out . Using these data to fabricate database and induct them by programming language . When a socket designer input necessary plug pull force and plug pin thickness , then a standard socket can be designed . Meanwhile , this program can automatically output suggested data of space for spring bussbar .
Using these suggested data to proceed socket design of America and China specification, fabricate mold and produce samples . Test these specimens and get their data of plug pull force to ensure these testing data are the same as simulation results of CAE .
According to the test and simulation as above , we can ensure the model suggested in the study is applicable for socket designer .
