Description

透明绝缘外壳
技术领域
本发明涉及绝缘外壳,并具体涉及用于电抽头或接头连接器的透明绝缘外壳以及与电抽头或接头连接器关联的标签盖罩。
背景技术
保护并绝缘抽头或接头的现有抽头或接头盖罩是黑色或彩色的,因此不透明,以致在关闭时看不见连接部。如果怀疑连接部有问题,则为了检查目的必须移开该盖罩。在移开过程中可能损坏连接部。特别地如果在特定电路中有许多连接器,则这种检查将非常费时。同样,在移开盖罩的时候,对处于通电状态中的电路执行这些检查是危险的。
因此允许抽头或接头的安装后检查是有利的。本发明的盖罩也提供用于抽头或接头连接部的改进的标记和识别保护。
发明内容
本发明具体涉及用于电连接器的透明外壳。该透明绝缘外壳包括:第一隔间,该第一隔间具有多个指;结构与第一隔间相同的第二隔间,该第二隔间具有多个指;其中,第一隔间和第二隔间互相安装到一起,以形成所述外壳;将所述多个指设置成呈一角度,用以夹持连接至外壳中的电连接器的电缆;以及第一和第二隔间中的至少一个还包括凹槽,该凹槽用于容纳标签以识别电连接器。
附图说明
图1是其内设置有电连接器的本发明的透明绝缘外壳的透视图;
图2是图1的透明绝缘外壳的分解图;
图3是具有延伸穿过主体的一对脊的图1的透明绝缘外壳的可选实施例的透视图;以及
图4是其内设置有电连接器的图3的透明绝缘外壳的侧视图。
具体实施方式
图1和图2所示的设计公开了一种根据本发明的优选实施例的用于电连接器90的透明绝缘外壳10。
外壳10由两个分离的相同的半个部分或隔间12a和12b构成。每半个部分或隔间12a和12ba具有由第一壁16a、16b,第二壁18a、18b和端部20a、20b限定的主体14a、14b。每半个外壳12a、12b的第一壁16a、16b和第二壁18a、18b借助新的闭锁系统合在一起以形成绝缘外壳。
闭锁系统的第一壁16a、16b包括具有两个凸起24a、24b的主外凸片22a、22b和从外壳内侧支撑并固定另外半个外壳的第二壁18a、18b的两个内凸片28a、28b。两个内凸片28a、28b具有侧面30a、30b和端部32a、32b引入斜面,该引入斜面有利于装配中两个半个外壳部分的相互定位。主外凸片22a、22b也包括用作外壳的闪络屏障的延伸端部26a、26b。
通过将半个外壳部分12a、12b紧压在一起,第二壁18a、18b被圈闭在第一壁16a、16b的内凸片28a、28b和外凸片22a、22b之间。每半个外壳的第二壁18a、18b都具有从壁的大约半高延伸到壁的顶部36a、36b的开孔34a、34b。由于两半外壳紧压在一起,主外凸片22a、22b的内侧上的凸起24a、24b插入到另一半外壳的第二壁18a、18b的开孔中,并将外壳锁在闭合位置中。
如果必要,在位于外主凸片22a、22b内侧上的凸起24a、24b之间插入平头电极螺丝刀或类似的工具,以将两半外壳彼此撬开而打开外壳。
每半个外壳具有延伸穿过半个外壳的内凸缘40a、40b。内凸缘40a、40b用来止挡电连接器以防止电连接器被拨出绝缘外壳。凸缘40a、40b具有容纳压接(crimp)在电连接器中的电缆的C-形中间部分42a、42b。
脊44a、44b被设置在每个主体14a、14b上的凸缘40a、40b的外侧,以便在其间形成凹槽48a、48b。凹槽48a、48b容纳标签或标记50以及标签罩52。重要的是将标签放置在外壳内部,以防止在完成连接并且将外壳卡合在一起连接器之后的对标签上信息的篡改。标签的内部放置的另一好处是标签罩和标签不会因被偶然地除去或脱落而丢失。
标签罩52包括在标签罩两侧上设置的凹口54。凹口54啮合外壳壁由此使标签罩52任何一侧朝外地被插入。
标签罩52的每侧都具有无光的毛面,该无光的毛面使标签罩52可被用作一分离的标签的支持件。如果没有标签,则可将信息直接写在标签罩无光的表面。
为利于标签50的去除,在用于撬具插入的各脊44a、44b之间提供开口46a、46b。
绝缘外壳的端部20a、20b包括多个窄指60a、60b,这些窄的指状物相对外壳劈面的成一窄角地从在每个外壳主体14a、14b向外延伸。这些角最小化支撑点,以使其它电缆线路被拖到外壳旁。指60a、60b彼此平行,且仅朝向它们顶端62a、62b略微收窄。指端的下侧具有阻止末端挤压(pinching)入或刺入(digging)电缆绝缘套的较小的平坦部分64a、64b。指的外边缘66a、66b是圆形以防止损伤安装者的手。指为充分柔韧和弹性以紧密贴近电缆以防止异物,如安装者的手指或工具穿透外壳而接触设置其中的电连接器。柔韧度取决于用在特定连接部中的电缆尺寸。因此,绝缘外壳被设计成可用于较宽范围的电缆尺寸。
因插入的电缆被推开的指弯曲,同时不接触电缆的其余指保持靠近在一起以防止工具或安装者的指意外插入通电的连接部中。
由于相当坚固并有弹性,指提供连接电缆的良好夹持并防止如果轻微移动绝缘外壳而产生的卡嗒卡嗒声。
外壳通过自身的特征和强度保持电连接器周围的稳固。而且,如果需要,可使用电缆系带或蜡绳增加稳固。
每半个绝缘外壳12a、12b具有外定位插槽70a、70b。当半个外壳部分12a、12b彼此固定时,定位插槽70a、70b对准以围绕外壳产生连续的插槽。将对准定位插槽设计为用来接纳卷绕外壳的电缆带76或蜡绳。外壳还包括与插槽70a、70b相邻设置、以容纳电缆系带头78的凹进部72a、72b,以及设置在插槽70a、70b侧面上和半个外壳部分的顶部的凸缘74a、74b。凸缘74a、74b有助于在环绕外壳的定位插槽中保持电缆带。
透明外壳能够实现不打开绝缘外壳对电连接器的的压接质量和电连接器上的所有标记的质量进行检测。
另外,绝缘外壳可在指上模制有确定的识别信息以便它不阻碍对外壳内的电连接器的观察。
图3和图4描述了用于电连接器的透明绝缘外壳的可选实施例。除上述特征外,可选实施例包括在每半个外壳中的一对夹持凸缘80a、80b。该夹持凸缘对80a、80b设置在外壳长度的中部。该夹持凸缘80a、80b用作电连接器的夹持物并且不会凸出超过电缆绝缘的外表面。没有夹持凸缘80a、80b,则只能通过在外壳和电缆绝缘之间的摩擦夹持抽头型电连接器。该固定方式不够有效。中心夹持凸缘80a、80b插入到插槽中,该插槽形成在确定类型的抽头电连接器中以有效地夹持外壳中的电连接器。
此外,在显示和描述本发明特定优选实施例的同时,对于本领域技术人员在不脱离本发明教导下进行的变化和改进都是显而易见的。在前面描述和附图中陈述的内容只起说明作用而不用于限制。当根据现有技术在其合适范围中认定本发明时发明的实际范围限定在后面的权利要求中。
