綠色製程發電機之引出導通裝置設計
A Design of Lead and Conduction Device for Green in-Process Generator
摘要
本研究開發了一個摩托車發電機專用的電流導通裝置，以模擬實車迴路與信賴性評價實驗方式，探討電樞電流導通裝置在不同尺寸參數設計下之導通電流的變化。此電樞電流導通裝置之設計概念，是採用不含鉛、鎘的環保綠色材料，使用端子接合技術來取代傳統銲錫作業的加工方法，改善銲錫作業時假銲狀況，減少假銲造成的不導通、重工報廢現象及銲錫產生的有毒氣體對人與空氣的污染。 由電樞電流導通裝置的測試評價實驗結果顯示導通裝置之導通效果會隨著端子的開口槽寬度變化而有所不同，當端子槽開口寬度為漆包線徑的70%時，可獲得較佳的導通效果。在端子固定腳壓著高度上，當U型端子槽寬0.7mm、電線之端子壓著高度為1.5mm、端子固定腳壓著面積與銅蕊未被擠壓面積壓縮比在85%時，可獲得較佳的導通效果。在引出電線之裸銅線有無表面處理的比較上，沒有表面處理的電線抵抗值很不穩定而容易發生氧化現象，溫昇測試時會產生很高的溫度，當沒做電鍍的電線通電流10安培及電壓14伏特下，溫度最高到達170℃。本研究之成果，不僅獲得電樞電流導通裝置之最佳化結果，亦可作為未來摩托車發電機之綠色電流導通裝置設計之參考。

This study develops an electricity conducting device exclusively for motorcycle generator. The techniques of benchmark circuit simulation and reliability appraisal test have been used to study the variation of electricity conduction induced with different size parameters for the design of amateur electricity conducting device. Prime concept behind this design is to develop a device using green materials which avoiding lead and cadmium. Terminal connection technology is adopted instead of conventional soldering process to improve false soldering condition, reduce non-conductivity, and to avoid heavy scraps and toxic gas generated during tin soldering that harms human health and causes air pollution. The completion of test appraisal experiment of amateur electricity conducting device suggests that the conductivity varies with the width of the open channel of the terminal. Better conductivity can be achieved when the width of the terminal open channel is 70% of the diameter of the coated wire. The study on the effect of height of the squeezed terminal fixed leg shows that when the width of the U shape terminal channel is 0.7 mm, terminal squeezed height of the wire is 1.5mm, and ratio of squeezed area of terminal fixed leg to un-squeezed area of the copper core is 85%, maximum conductivity can be obtained. It is observed that the copper wire is vulnerable to oxidation without surface treatment which makes impedance unstable and produces high temperature during temperature rise test. Temperature rises up to 170℃ on flowing 10A current through a wire without electroplating at 14 V. The outcome of this study provides not only the optimal effect of the amateur electricity conducting device, but also serves as a reference for design of green electricity conducting device of motorcycle generator in future.
