本发明的实施方式
[0024] 在详细描述实施例之前， 应该理解的是， 本发明不限于本申请中下文或附图中 所描述的详细结构或元件排布。 本发明可为其他方式实现的实施例。 而且， 应 当理解， 本文所使用的措辞及术语仅仅用作描述用途， 不应作限定性解释。 本 文所使用的"包括"、 "包含"、 "具有"等类似措辞意为包含其后所列出之事项、 其 等同物及其他附加事项。 特别是， 当描述 "一个某元件 "吋， 本发明并不限定该元 件的数量为一个， 也可以包括多个。
[0025] 如图 1至图 5所示， 本发明提供一种通讯缆线， 包括线缆 10和连接在线缆 10—端 的水晶头 12。 水晶头 12包括水晶头本体 14、 金属屏蔽罩 16、 按压弹片 18以及一 第一塞子 20。
[0026] 水晶头本体 14具有相反的第一端 22、 第二端 24以及形成在所述第一端 22和第二 端 24之间的一内腔 26。 第一端 22设置有金属端子 28， 第二端 24设有与内腔 26连 通的幵口 30， 第一塞子 20安装在幵口 30内。 线缆 10包括数股线芯 32以及包覆数 股线芯的护套 34， 线缆 10—端从幵口 30插入内腔 26并与设置于水晶头第一端 22 的金属端子 28电性连接。
[0027] 在所示的实施例中， 水晶头本体 14具有四个本体侧壁， 包括第一本体侧壁 36、 第二本体侧壁 38、 第三本体侧壁 40和第四本体侧壁 42。 上述四个本体侧壁合围 形成水晶头本体 14的内腔 26， 其中， 第一本体侧壁 36与第三本体侧壁 40相对， 第二本体侧壁 38与第四本体侧壁 42相对。 第二本体侧壁 38上设有一与内腔 26连 通的第一幵孔 44， 第四本体侧壁 42上连接用于与一连接器插口卡扣连接的按压 弹片 18， 所述连接器插口为一电子设备上的插口， 用以收容并与水晶头 12电性 连接。
[0028] 水晶头第二端 24的幵口 30由水晶头本体 14的数个边框围成， 每个边框具有位于 幵口 30的边框内侧和背离幵口 30的边框外侧， 其中一个边框向外弯曲凸起以在 其面向幵口 30的边框内侧上形成一凹面， 在其背离幵口 30的边框外侧上形成一 凸面。
[0029] 在所示的实施例中， 水晶头幵口 30由四个边框围成， 包括第一边框 46、 第二边 框 48、 第三边框 50和第四边框 52， 其中第一边框 46和第三边框 50为两相对的短 边， 第二边框 48和第四边框 52为两相对的长边， 向外弯曲凸起的边框为其中一 个长边。 其中， 四个边框位于四个本体侧壁朝向水晶头本体 14第二端 24方向的 外缘处。 具体来说， 第一边框 46位于第一本体侧壁 36的外缘处， 第二边框 48位 于第二本体侧壁 38的外缘处， 第三边框 50位于第三本体侧壁 40的外缘处， 第四 边框 52位于第四本体侧壁 42的外缘处。 第二边框 48位于第一幵口 44与水晶头第 二端 24之间。
[0030] 本实施例中， 向外弯曲凸起的边框为第二边框 48， 第二边框 48具有位于幵口 30 内的边框内侧 54和背离幵口 30的边框外侧 56， 第二边框 48向外弯曲凸起在其面 向幵口 30的边框内侧 54上形成一弧形凹面， 在其背离幵口 30的边框外侧 56上形 成一与所述弧形凹面对应的弧形凸面。 边框向外凸起， 相当于在不改变水晶头 1 2整体结构的基础上， 增大了幵口 30和内腔 26的尺寸。 采用具有这样幵口 30的水 晶头 12， 当线缆 10插入内腔 26吋， 线缆 10可以连同护套 34—起插入， 只有在接 近金属端子 28的位置才需要去除护套 34。 换句话说， 插入内腔 26的线缆部分包 括一段护套被去除的部分 58和一段护套未被去除的部分 60 (如图 5所示） ， 这样 只有一段线芯的绞距被破坏， 且这种破坏不会造成大的信号串扰， 是可以接受 的。 因此， 这样大大减小对双绞线位于内腔 26中的绞距的破坏， 降低信号串扰 的影响。
[0031] 按压弹片 18连接至水晶头本体 14设置第四边框 52的那一侧， 也就是说按压弹片 18所在的边框与向外弯曲凸起的边框相对。 按压弹片 18用于当水晶头 12插入电 子设备接口中后， 与接口弹性卡扣以锁住水晶头 12而防止意外脱落。 当需要拔 除水晶头 12吋， 需要按压该按压弹片 18， 解除卡扣， 才能将水晶头拔出。 由于 按压弹片 18所在的边框与向外弯曲凸起的边框相对， 按压弹片 18的按压动作不 会受到任何影响。 按压弹片 18已为本领域技术人员所熟知， 因此不再详细描述
[0032] 应当理解的是， 本实施例中将所述凹面和凸面设计为弧形面， 在其他实施例中 ， 也可以设计成其他形状的凹面和凸面， 例如， V形凸面和 V形凹面， 或者拱形 凸面和拱形凹面， 只要能使得幵口 30的横截面积增大且符合设计需求即可， 本 发明并不对此进行限定。
[0033] 也应当理解的是， 本实施例中是以水晶头幵口 30由四个边框围成来进行详细说 明的， 根据水晶头的具体设计需要， 水晶头幵口 30也可以是由其他数量的边框 围成， 只要能使得幵口的横截面积增大且符合设计需求即可， 本发明并不对此 进行限定。
[0034] 金属屏蔽罩 16套设在水晶头本体 14上， 金属屏蔽罩 16对应第一幵孔 44位置设有 能够朝向第一幵孔 44内弯折变形的至少一金属弹片 62。
[0035] 具体而言， 请参考图 1， 金属屏蔽罩 16具有一与第一幵孔 44对应的第二幵孔 64 ， 金属屏蔽罩 16包括第一屏蔽罩侧壁 66、 第二屏蔽罩侧壁 68和第三屏蔽罩侧壁 7 0， 其中第一屏蔽罩侧壁 66和第三屏蔽罩侧壁 70分别自第二屏蔽罩侧壁 68的两相 对边延伸。 当金属屏蔽罩 16套设于水晶头本体 14上吋， 第一屏蔽罩侧壁 66与第 一本体侧壁 36贴合在一起， 第二屏蔽罩侧壁 68与第四本体侧壁 42贴合在一起， 第三屏蔽罩侧壁 70与第三本体侧壁 40贴合在一起。 第一幵孔 44形成于第二本体 侧壁 38上， 第二幵孔 64形成于第一屏蔽罩侧壁 66与第三屏蔽罩侧壁 70之间， 所 述至少一金属弹片 62可转动地连接至第一屏蔽罩侧壁 66和 /或第三屏蔽罩侧壁 70 上。 本实施例中金属弹片 62设为两个， 所述两个金属弹片 62分别可转动地连接 至第一屏蔽罩侧壁 66和第三屏蔽罩侧壁 70上。 第一屏蔽罩侧壁 66远离第二屏蔽 罩侧壁 68的一边缘朝向第三屏蔽罩侧壁 70延伸出一第一金属片 72， 第三屏蔽罩 侧壁 70远离第二屏蔽罩侧壁 68的一边缘朝向第一屏蔽罩侧壁 66延伸出一第三金 属片 74， 当金属屏蔽罩 16套设在水晶头本体 14上吋， 第一金属片 72和第三金属 片 74贴靠在第二边框 48上。
[0036] 在所示的实施例中， 每一金属弹片 62具有一朝向对方金属弹片的自由末端 76， 自由末端 76的一角设置一缺口 78， 且两自由末端 76的缺口 78相互错幵， 以使得 两金属弹片 62的转动互不影响。
[0037] 请同吋参考图 1和图 5， 线缆 10还包括数股线芯 32、 包覆所述数股线芯 32的屏蔽 网 80以及包裹在屏蔽网 80上的护套 34。 线缆 10还设有与屏蔽网 80电性接触的接 地线。 在水晶头 12内部， 有一段线缆 10的护套 34被去除。 当金属弹片 62朝向第 一幵孔 44内弯折变形吋， 金属弹片 62抵靠在屏蔽网 80上与其电性连接， 从而达 到接地屏蔽的效果。 因此， 当组装水晶头 12与线缆 10吋， 只需将线缆头部的一 段护套去除， 并去除头部一段屏蔽网， 保留一段靠近未去除的护套的屏蔽网 80 ， 然后直接将前述处理好的线缆头部插入水晶头内腔 26中， 然后将金属弹片 62 朝第一幵孔 44的方向按压， 直至其抵靠在屏蔽网 80上与其电性连接即可。 此安 装过程简单， 并且能够获得良好的接地屏蔽效果。 为了能够获得良好的电性接 触， 插入到水晶头内腔 26的线缆头部上保留的一段屏蔽网 80应至少延伸至对应 其中一个金属弹片 62的位置， 这样使得按压金属弹片 62即可获得良好的接地屏 蔽效果。
[0038] 应当理解的是， 本实施例中在金属弹片 62的自由末端 76设置缺口 78， 且使缺口 78相互错幵的方式使得两金属弹片 62的转动相互不受影响， 但本发明并不对此 进行限定， 在其他实施例中， 也可采用其他方式， 例如将自由末端 76设置为相 互啮合形式的齿轮状。
[0039] 也应当理解的是， 在其他实施例中， 根据设计需求及各方面因素， 也可以将金 属弹片 62的数量设置为一个或者多于两个。
[0040] 第一塞子 20安装在幵口 30内， 第一塞子 20具有一内孔 82， 内孔 82与内腔 26连通 。 为了使得水晶头 12能够适应多种线径， 水晶头 12还包括第二塞子 84。 请同吋 参考图 6和图 7， 第二塞子 84可更换地装设于第一塞子 20的内孔 82内， 第二塞子 8 4具有一内孔 86， 第二塞子 84的内孔 86与内腔 26连通， 线缆 10—端自第二塞子 84 的内孔 86插入内腔 26并与金属端子 28电性连接， 同吋第二塞子 84被挤压在护套 3 4外表面与第一塞子 20的内壁之间。
[0041] 在所示的实施例中， 第一塞子 20为硬质胶塞， 并与幵口 30压入配合， 第一塞子 20的内孔 82为圆形内孔 82， 第二塞子 84为与圆形内孔 82配合的环形第二塞子 84 ， 第二塞子 84为软质塞子， 例如人造橡胶垫， 其弹性收缩的性质使得线缆 10与 第二塞子 84之间紧密挤压在一起， 第二塞子 84的内孔 86为与线缆 10配合的圆形 内孔 86。 应当注意的是， 第一塞子 20为硬质胶塞， 第二塞子 84为人造橡胶垫仅 为本发明的一种实施方式， 在其他实施例中， 根据具体需求第一塞子 20和第二 塞子 84也可以采用其他的材质。
[0042] 第一塞子 20包括与幵口 30形状配合的塞头 88及自塞头 88朝向内腔 26延伸的塞壁 90， 当第一塞子 20塞进内腔 26内后， 塞壁 90与水晶头本体 14的内壁抵靠， 从而 将第一塞子 20与水晶头本体 14固定连接。 在本实施例中， 塞壁 90的数量为两个 且对称分布。 [0043] 第二塞子 84外围设有至少一挡止部 92， 以防止第二塞子 84从第一塞子 20的内孔 82中脱落。 在所示的实施例中， 所述至少一挡止部 92包括设在第二塞子 84外围 的沿径向凸起的两对称挡止部 92。 在将第二塞子 84沿轴向安装入第一塞子 20的 内孔 82的过程中， 第二塞子 84自第一塞子 20的内侧， 即设置塞壁 90的一侧塞入 第一塞子 20的内孔 82中， 两挡止部 92卡在第一塞子 20的内侧上， 以防止当线缆 1 0被拉扯吋， 第二塞子 84从第一塞子 20的内孔 82中脱落。 如图 6所示， 第一塞子 2 0的内侧设有与挡止部 92配合的挡槽 93。 应当理解， 在其他实施例中， 挡止部 92 也可以为其他数量。 在其他实施例中， 也可以采用其他实施方式来防止第二塞 子 84从第一塞子 20的内孔 82中脱落， 或者将第二塞子 84固定于第一塞子 20的内 孔 82中， 本发明不对此限定。
[0044] 为了使得第一塞子 20与水晶头本体 14的连接更为稳固， 在所示的实施例中， 第 一塞子 20还包括自塞头 88朝向内腔 26延伸的弹性卡勾 94， 弹性卡勾 94可在竖直 方向上实现小范围的弹性伸缩， 对应地， 水晶头本体 14设有与弹性卡勾 94配合 的卡槽 96。 在本实施例中， 卡槽 96设置在向外弯曲凸起的第二边框 48 (即第二 本体侧壁 38) 上， 且卡槽 96与第一幵孔 44连通。 在第一塞子 20被压入幵口 30内 吋， 塞头 88位于幵口 30处， 塞壁 90抵靠在内腔 26内壁， 即水晶头本体 14的内壁 上， 弹性卡勾 94卡入卡槽 96内， 以将第一塞子 20与水晶头本体 14牢固固定。 在 本实施例中， 弹性卡勾 94和卡槽 96的数量分别为 2个， 但在其他实施例中可以是 其他数目。
[0045] 应当理解的是， 为了将第一塞子 20与水晶头本体 14稳固连接， 本实施例采用设 置弹性卡勾 94与卡槽 96配合的方式， 在其他实施例中， 也可以采用其他实施方 式， 本发明不对此限制。
[0046] 综上所述， 本发明提供一种能够降低绞距破坏程度的水晶头， 水晶头的幵口由 两相对短边框和两相对长边框围成， 幵口与水晶头内腔连通， 每个边框具有位 于幵口的边框侧和远离幵口的边框侧， 其中一个长边框外向弯曲凸起以在其面 向幵口的边框侧上形成一凹面， 在其背离幵口的边框侧上形成一凸面， 以此来 增大幵口的横截面积。 本发明还提供一种通讯缆线， 通过增大其幵口的横截面 积使得插入内腔的线缆部分只有一段护套被去除， 而靠近幵口的一段护套可以 不用去除， ， 从而缩短了绞距被破坏的线缆的长度， 从而有效降低双绞线之间 的信号串扰， 增强了网络传输效果。 金属屏蔽罩通过设置能够朝向第一幵孔内 弯折变形的金属弹片， 以使得金属弹片抵靠在屏蔽网上， 结构简单， 设计巧妙 ， 从而实现良好的屏蔽接地效果。 本发明还在第一塞子的内孔中可更换地安装 一第二塞子， 第二塞子可根据线缆的线径而自由更换， 以使得水晶头能够适用 多种线径的线缆。
本文所描述的概念在不偏离其精神和特性的情况下可以实施成其它形式。 所公 幵的具体实施例应被视为例示性而不是限制性的。 因此， 本发明的范围是由所 附的权利要求， 而不是根据之前的这些描述进行确定。 在权利要求的字面意义 及等同范围内的任何改变都应属于这些权利要求的范围。
