為達到上述的發明目的，本發明所採用的技術手段為 叹计一種一種提升被動元件對湧浪電流耐受性的方法，其 透過將一金屬片設於該被動元件之電流迴路中，使通過該 金屬片之電流能均勻分散，並可進一步將該金屬片設置於 被動元件之電極與端子之間。 “本&明的優點在於，藉由金屬片的設置以增加端子與 電極的接觸面^，使得端子與電極之間i面接冑，則電； ，過時將電流分散，故當通過大電流時，目電流分散而不L 產生燒钱現象’吨高本發明維持正常運作的機率。 【實施方式】 陶瓷片 睛蒼閱第一及二圖所示，本發明包含有 6 200823933 〇 )、一銀電極（2 0 )、一第一端子（3 〇 )、一第二 端子（3 1 )及一金屬片（4 〇 )。 前述之銀電極（2 0 )固設於陶瓷片（^ 〇 )表面， 第-及第二端子（30) (31)分別與銀電極（2〇) 之前後兩側相連接，端子（30) (31)跨設於陶瓷片 (10)上，第一端子（30)跨設於陶曼片（1〇)上， 且第一端子（3 0 )與銀電極（2 〇 )間設有金屬片（4 〇 )，第-端子（3 0 )與金屬“ 4 〇 )呈線接觸，該 金屬片（40)為高導電率的金屬片體，例如鍍錫、鍍銀 銅片等，攻樣則第一端子（3 〇 )與銀電極（2 〇 )間係 呈面接觸，因此，當大電流通過時，金屬片（4 〇 )分散 電流，則使得銀電極（2 0 )不產生銀層燒蝕現象。 請參閱第三及四圖所示，本發明進一步包含有一絕緣 片（5 0 )及一熱熔絲（6 〇 )。熱熔絲（6〇）的一端 和第一端子相接，另一端跨過絕緣片（5 〇 )與金屬片（4 0 )相接，因此，當大電流通過時，金屬片（4 〇 )分散 電流，則使得銀電極（2〇)不產生銀層燒蝕現象。 通過增设金屬片（4 0 )，從而提高被動元件耐受湧 浪電流衝擊的能力，這類被動元件可包括防雷型壓敏電隍 器、具有熱保護功能的壓敏電阻器、以及㈣電流抑制刑 NTC熱敏電阻器等被動元件。 < 【圖式簡單說明】 第一圖為本發明之正視圖 第二圖為本發明之側視圖 200823933In order to achieve the above object, the technical means adopted by the present invention is a method for improving the resistance of a passive component to surge current by providing a metal piece in a current loop of the passive component to pass The current of the metal piece can be uniformly dispersed, and the metal piece can be further disposed between the electrode of the passive component and the terminal. "The advantage of this & Ming is that the contact surface of the terminal and the electrode is increased by the arrangement of the metal piece, so that the i-face is connected to the electrode between the terminal and the electrode, and electricity is discharged; when the current is excessively distributed, when passing a large current , the current is dispersed without L. The phenomenon of burning money is high. [Embodiment] The ceramic sheet is shown in Figures 1 and 2, and the present invention includes 6 200823933 〇), a silver An electrode (20), a first terminal (3 〇), a second terminal (3 1 ) and a metal piece (4 〇). The silver electrode (20) is fixed on the surface of the ceramic piece (^ 〇) The first and second terminals (30) (31) are respectively connected to the front and rear sides of the silver electrode (2〇), and the terminal (30) (31) is spanned on the ceramic piece (10), and the first terminal (30) Between the first terminal (30) and the silver electrode (2 〇), a metal piece (4 〇), a first terminal (3 0 ) and a metal "4 〇" are disposed across the Tauman sheet (1 〇). In line contact, the metal piece (40) is a high-conductivity metal piece, such as tin-plated, silver-plated copper, etc., and the first terminal (3 〇) and the silver electrode are sampled. 2 square) surface contact between the lines was, therefore, when a large current through the metal sheet (4 square) current dispersion, such that the silver electrode (20) does not generate silver layer ablation phenomenon. Referring to Figures 3 and 4, the present invention further includes an insulating sheet (50) and a thermal fuse (6 〇). One end of the thermal fuse (6〇) is connected to the first terminal, and the other end is connected to the metal piece (4 0 ) across the insulating sheet (5 〇), so when a large current passes, the metal piece (4 〇) Dispersing the current causes the silver electrode (2〇) to not cause ablation of the silver layer. The ability of passive components to withstand surge current surges is enhanced by the addition of metal sheets (40), which may include lightning protection type varistor, varistor with thermal protection, and (iv) current Suppress passive components such as NTC thermistors.
