以下将结合附图来叙述本公开的一些优选实施例， 以便详细地说明其 技术方案。
参照图 1-2，所示分别为本公开的范例性熔断器 100的示意图和分解图。 图中所示的范例性熔断器 100为双管式熔断器 100，其包括两端开口的外管 体 70、 设置在所述外管体 70之内的两端开口的内管体 60、 设置在所述内 管体 60之内的熔芯 50、设置和覆盖在所述外管体 70两端的左右内铜套 40、 设置和覆盖在所述内铜套 40和所述外管体 70两端之上的左右外铜套 20; 在一些实施例中， 熔断器 100为单管式熔断器， 即其只包括外管体 70 ; 其它结构则与图 1 -2所示的大体相同。
在一些实施例中， 所述外管体 70的外表面具有可印刷的标注性能和参 数的部分。
在一些实施例中， 所述熔芯 50采用线型或片型的形式。 优选地， 所述 熔芯采用具有多个相互隔开的穿孔的片型的形式， 正如图 2所示。
在一些实施例中， 所述熔芯沿所述内管体的轴向方向延伸； 和 /或所 述熔芯的轴线与所述内管体的轴线重合或平行， 正如图 2所示。 根据本公开， 所述内铜套 40的一端为邻接外管体的第一开口端以及另 一端则为远离外管体的第一封闭端， 所述第一封闭端的端面具有第一开口； 所述第一开口端优选通过冲压来与所述外管体成过盈配合连接。
相比于现有技术的两端皆为开口端的具有相同直径的内铜套， 本公开 的内铜套具有较多的铜材， 这样可以协助保险丝 (熔断器)减低内阻、 保持良 好的电学接触及降低保险丝 (熔断器)通电时的温升。
在一些实施例中， 所述第一开口的形状为半圆形、 三角形、 矩形、 多 边形和 /或其组合。 如图 3所示， 所述第一封闭端的端面 44具有半圆形的 第一开口 42。在一些实施例中， 本公开的熔芯 50的未端延伸穿过所述第一 开口 42， 并优选通过点焊固定在所述第一封闭端的端面 44上。
相比于现有技术的熔断器， 其熔芯 /熔丝一般通过锡线焊接内铜套的 环边 /端侧来固定， 本公开的端面 44 提供一种支承面， 从而使到熔芯 50 可通过点焊方式来固定而无需使用焊锡方法，这可减低保险丝 (熔断器)受外 热加温而影响熔芯之导电性。
如图所示， 本公开的所述外铜套 20的一端为开口端以及另一端则为封 闭端， 所述外铜套 20的开口端优选通过冲压来与所述第一封闭端和 I或所 述外管体成过盈配合连接。 在工作时， 所述熔断器的外铜套 20通过公知的 夹持件与电路板连接， 或可插入电路板的专用插座上来保护电路， 使之不 受过大的电流的损害。
在一些实施例中， 熔断器 100还包括设置和覆盖在所述外铜套和所述 外管体两端之上的左右插脚铜套 10。
如图 4a-4b所示， 所述插脚铜套 10的一端为第二开口端以及另一端则 为第二封闭端， 所述第二封闭端的端面 14优选通过冲压来形成开口部分和 插脚部分 12，所述插脚部分配置成向所述第二封闭端的端面 14的外侧弯折 180° 以形成沿所述插脚铜套的径向方向延伸的插脚或插件； 所述第二开口 端优选通过冲压来与所述外铜套 20的封闭端和 I或所述外管体成过盈配合 连接。
如图所示，所述插脚部分优选为 T形插脚部分 12， 所述插脚部分 12配 置成向所述第二封闭端的端面 14的外侧弯折 180° 以使 T形插脚部分的长 型部分形成沿所述插脚铜套的径向方向延伸的插脚或插件， 所述插脚或插 件的延伸方向与所述熔断器的轴线方向成正交或相互垂直。
如图所示： 插脚铜套安装在保险丝（熔断器)两端上， 以使熔断器可安 装或固定在电路板 (PCB)上使用。插脚铜套以机械方式固定，省却使用焊锡， 减低保险丝（熔断器)在过锡炉时 （回流焊 /波锋焊） 受外热加温而影响保 险丝（熔断器）中熔丝之导电性； 保险丝（熔断器)可与插脚铜套一体成型， 方便直接焊接在 PCB 上。 本公开的这种插脚铜套， 使到使用者难以或不可 能把插脚铜套从保险丝 (熔断器)拆除， 这有别于现有技术的保险丝铜夹的 应用。换句话说，如果需要更换保险丝 (熔断器）的话，必须将整个保险丝 (熔 断器)连同插脚铜套从 PCB上拆除， 这要求有经验的技术人员和相关器材来 替换保险丝 (熔断器）， 保障一般非技术人员的安全， 也对最终使用者有保 障。
而且这种保险丝（熔断器）插脚铜套的形状设计为一种节省物料的设 计， 因为插脚部分 12本身是从插脚铜套的端面或底部往外面反折而成， 充 分利用了插脚铜套的端面或平面部分的材料。
在一些实施例中， 熔断器 100还包括设置在所述外铜套 20和所述内铜 套 40 之间和优选覆盖所述第一封闭端的端面上的点焊部分之上的阻断件 30， 所述阻断件 30用絶缘材料制成以及配置成提高所述熔断器的电流和 I 或电弧阻断能力。 如图 2所示， 阻断件 30可成型为圆形； 在其它的实施例 中， 阻断件 30可成型为半圆形、 三角形、 矩形、 多边形和 /或其组合。 在一些实施例中， 所述外管体和内管体由两种不同材料构成， 并且紧 贴地套在一起以防止松脱， 其中所述外管体用可耐高温的材料构成， 而所 述内管体则用轻巧和便于生产的材料构成， 反之亦然 (可取决于特定应用）； 以及所述外管体和内管体配置成提高所述熔断器的电理性能和降低要求高 电理性能的熔断器的总成本。
在一些实施例中， 所述外管体优选由陶瓷或玻璃制成以及所述内管体 优选由玻璃纤维、 聚酯、 树酯、 玻璃纤维树脂和 /或三聚氰胺制成； 在另 一些特定实施例中， 所述内管体可优选由陶瓷或玻璃制成以及所述外管体 可优选由玻璃纤维、 聚酯、 树酯、 玻璃纤维树脂和 /或三聚氰胺制成； 所 述外管体和内管体的内径和外径的尺寸设计成便于使两者紧贴地套在一 起； 和 /或所述外管体和内管体通过在两者之间施加的黏贴物或黏贴剂来 达到固定和 /或紧贴的效果。
通过使用本公开的双管式熔断器， 可使保险丝 (熔断器）的分断能力可 大大高于单管式熔断器； 其次，可降低材料的成本；另外，可以解决保险丝 (熔断器)上的性能标注问题， 使到无需使用较易脱落和受损的贴纸标签。 载于所附的权利要求的特征 （共同地及在适当之处可单独地） 形成本 公开的一部分， 并在此引入作为参考。
虽然本文业已叙述了不同的范例或实施例， 但应该理解的是， 它们是 用于说明而不是用于限制保护范围。 例如， 在本文所提供的范例性应用中， 插脚铜套和内外铜套等等构作分别显示为或配置为具有环形 /圆形的形状， 但在不丧失一般性的情况下， 还可使用根据本公开的实质内容的其它形状 和结构。 应当理解的是， 不同的范例性实施例的部分或部件在适当情况下 可以相互组合和 /或混合搭配， 以形成其它变型而不丧失一般性。
