本发明的较佳实施方式
针对手机充电器输出端子的连接器在手机充电时发生烧熔的问题， 申请 人通过不断的探索和研究发现， 用户在使用过程中， 异物进入， 插头插座斜 向插拔破损， 插头用力过大弯折折断， 形成大量导电液体和金属粉末， 造成 数据线在插头内部微短路， 微短路无法达到充电器短路保护条件， 导致充电 器持续输出功率， 在数据线插头处转化形成热量， 最终导致数据线熔化。
鉴于上述的分析， 本发明实施例旨在提供一种改进的电连接器， 所述连 接器包括屏蔽外壳， 其改进之处在于， 屏蔽外壳棵露内壁设置有绝缘层。
相应地， 本发明实施例并不限定设置绝缘层在棵露内壁上的面积和相应 的位置， 只要两个连接器屏蔽壳体在插拔过程中， 会彼此接触内壁存在设置 绝缘层的部分， 即可使得配合插拔的两个电连接器在插拔过程中， 在一定程 度上减少发生微短路的可能性， 体现本发明实施例的技术效果。
相应地， 该所述绝缘层可以为粘贴设置的绝缘薄膜， 可选地， 还可以为 喷涂设置的绝缘漆层。 本发明实施例对绝缘层的材质不做限定， 只要达到绝缘作用即可。
借助于该发明实施例的技术方案， 手机终端厂家可以广泛釆用， 使得充 电器的充电安全得到保证， 赢得市场好评， 减少投诉和不必要的赔偿。
本发明实施例的技术方案可适用于任何具有金属外壳， 且可能发生微短 路的电连接器， 本发明实施例对电连接器的类型和形状不做限定。
以下结合附图以 Micro USB接口的电连接器为例对本发明实施例的技术 方案进行说明：
釆用 Micro USB接口的充电器和手机如图 1所示， 申请人通过实际故障 品分析发现， 大部分微短路发生充电器和手机电连接器的第 1个端子 （pin ) 和连接器金属外壳间距较近， 易发生微短路。 连接器金属外壳在充电器和手 机内部接地。 其中， 第 1个端子和第 5端子分布在连接器两侧， 第 1个端子、 和第 5个端子之间发生微短路和第 1个端子、 第 5个端子同时与金属外壳发 生微短路可能性很小。
电连接器的金属外壳主要起到屏蔽作用， 如图 2所示， 釆用一种新型连 接器金属外壳 002 内壁棵露内壁增设一层绝缘层 001 , 图示电连接器中， 所 述屏蔽外壳只在正对所述导电端子接触面的内壁是棵露的， 因此只在正对所 述导电端子接触面的内壁上设置有绝缘层。
相应地， 该绝缘层可通过内壁喷涂绝缘漆， 或内壁贴绝缘薄膜； 这样可 以有效避免内部电源端子和金属外壳微短路， 同时不影响连接器屏蔽效果。

导电金属外壳 105需要进行特殊的加工处理增设绝缘层 106, 如内壁喷 涂绝缘漆， 或内壁贴绝缘薄膜， 导电金属外壳 105与前胶芯 104、 卡钩 103、 后胶芯 102、 以及一组端子 101组装好后， 由于 105 内壁增设的绝缘层 106 使得其与一组端子 101处于绝对绝缘状态无论发生形变或者外加通过外接导 体杂质接触都不会发生微短路。
如图 4所示， 导电金属片 201、 202、 203为导电金属壳 105展开图， 其 中 201为内壁喷涂绝缘漆， 202为内壁贴绝缘薄膜， 203为底部接触面使用绝 缘材质， 其中阴影部分别表示内表面喷绝缘漆， 贴膜绝缘膜， 以及更改底部 材质的覆盖范围。
