背景技术
[0002] 保险丝 （或称熔断器、 熔丝） 是一种连接在电路上， 用以保护电路的一次性组 件， 其中配置有以金属线或金属片制成的熔丝线； 当电路上的电流或突波过大 吋， 或者电能功率过大时， 可造成该熔丝线产生高温而熔断， 形成开路， 以中 断电路上的电能传导， 保护电路免于烧毁。
[0003] 现有的保险丝结构， 通常是在一绝缘底座两端分别配置有一电极， 再于两电极 上焊接一熔丝线， 使用吋可将保险丝的两电极分别焊接在电路上， 使电路上的 电能从其中一电极经过熔丝线传导至另一电极和电路。
技术问题
[0004] 然而， 这类保险丝的电极通常是一种金属片， 在贴覆于底座表面以后， 使电极 的金属片在底座表面呈平直形态， 而现有的熔丝线则通常是一种断面呈圆形轮 廓的金属线或金属丝， 因此当熔丝线配置在电极表面时， 为线 （熔丝线） 对面 （电极） 的接触型态， 造成熔丝线与电极的接触面积难以提升的问题， 容易影 响保险丝在组合熔丝线后的导电效率和可靠性。
[0005] 此外， 现有的保险丝的熔丝线在熔断时容易发生爆裂、 电弧等现象， 如果没有 适度地释放前述爆裂能量， 将导致保险丝外壳爆开而发生危险， 因此现有保险 丝都是在其底座设置用以释放爆裂能量的通孔； 但是， 当保险丝焊接或黏着在 电路板或设备上时， 该底座的通孔容易被焊料或黏胶覆盖堵塞， 而丧失作用。 问题的解决方案

[0030] 可了解的是， 借由该熔丝线 4一端外周面与该第一弯曲片 21凹接面 212彼此以面 贴面方式相互接合、 以及该熔丝线 4另一端外周面与该第二弯曲片 31凹接面 312 彼此以面贴面方式相互接合的结构， 以增加该第一电极 2、 该第二电极 3与该熔 丝线 4的接触面积， 借此提升保险丝在组合该熔丝线 4后的导电效率和可靠性。
[0031] 如图 1、 图 2、 图、 4所示， 在另一可行的实施例中， 该盖体 5的顶面 51或侧面 52 上， 设有一连通该空穴 16的通孔 53 , 使该通孔 53位于该盖体 5与该底座 1的接合 部位， 该通孔 53能够释放该熔丝线 4在熔断时所产生的爆裂能量； 如此， 当该底 座 1焊接或黏着在电路板或设备表面时， 由于该通孔 53位于在该盖体 5上， 没有 将通孔设在底座， 而使该通孔 53远离电路板或设备的焊料或黏胶， 可避免该通 孔 53因堵塞焊料或黏胶而丧失作用。
[0032] 如图 3、 图 4所示， 在一可行的实施例中， 该熔丝线 4一端、 该第一支撑部 14与 该第一翼部 141、 142之间填充有一绝缘层 61， 该该熔丝线 4另一端、 该第二支撑 部 15与该第二翼部 151、 152之间填充有另一绝缘层 62; 该绝缘层 61、 62可包覆 该熔丝线 4两端， 减少该熔丝线 4暴露在该空穴 16的体积， 并在组合该底座 1及该 盖体 5时， 该绝缘层 61、 62有缓冲的作用， 确保组合时， 该第一翼部 141及该第 二翼部 151接点不会受到挤压而破坏结构， 进而达到保护的作用。
[0033] 综上所述， 以上所述仅为本发明的较佳实施例， 不能用以限定本发明可实施的 范围， 凡本技术领域的人士所明显可作的变化与修饰， 皆应视为不悖离本发明 的实质内容。
