Abstract:	連接器端子的功能主要最為訊號及電流導通之用，隨著時代演變，連接器體積愈來愈小，內部端子結構也愈複雜，端子模具本身生產時就需特別留意，若組立或是維修手法不留心，很容易造成端子歪斜或是表面有刮傷等異常，是以如何有效控管現場生產的模具，是製造管理的關鍵。本研究探討端子在生產時造成歪斜的各項因素，透過了解該些因素，從中尋找能有效降低端子歪斜的辦法。本研究採用鈹銅合金C1720R-1/4H，其厚度為0.25mm，端子最細處的寬度為0.23mm，由於端子寬度不足2倍材厚，在沖切時容易發生歪斜的現象。研究結果顯示，若在沖切過程中，能確保端子左右兩側受力平均，可有效改善端子歪斜的情況，由數據得知，可有效降低57%的不良率。本研究之成果，不僅有助於了解製程對於端子歪斜的影響，還可以當作後續模具設計和維護的參考。 ;The function of terminal block connector is mainly for signaling and conduct electricity. Nowadays, the size of the connector is getting smaller, and the internal terminal structure is getting more complicated. Abnormalities such as crooked terminals or scratches on the surface may occur by unconscious assembling. Thus, the key is how to effectively manipulate the mold and procedures. This study investigates the factors that cause crooked terminals in production process. Through understanding the effects of these factors, the solutions of reducing the crooked terminals could be proposed in the present study. This study apply beryllium copper alloy C1720R-1/4H (thickness: 0.25mm; width of the smallest terminal: 0.23mm). We discovered that it is easy to skew when punching because the width of the terminal is less than 2 times of the thickness. The results of this study show that if the force on the left and right side of the terminal is evenly distributed during the punching process, the distortion of the terminal can be improved. The results of this study will not only lead us understand the influence of the process on the skewed terminals, but also serve as a reference for the progressive die design and maintenance.
