Description
本申请涉及机械技术领域,尤其涉及的是一种用于密封线缆的可拆卸连接装置及通信终端盒。
在光缆入户段线缆布放过程中,在将光缆插入光纤接头盒后,需要对光缆进行密封和固定,一般采用热缩管密封方式对光缆进行密封,但使用热缩密封方式密封的光缆口无法重复开启,不便于维修和替换等操作,并且需使用热风枪等专用工具,此类专用工具需电源,一般野外施工取电较困难,由此可见,该种密封方式适用的场景有限。
为突破依赖专用工具的限制,目前主要采用机械密封方式对光缆进行密封。但在机械密封方式中,需要安装较多密封零部件,且对这些密封零部件的安装顺序有严格要求,操作步骤复杂,容易出现返工特别是针对多根光缆插入一个光缆孔的场景,其次,在后续增加缆时会影响到之前已经开通业务的光缆,也不便于单缆管理。
发明内容

本申请第一方面提供一种用于密封线缆的可拆卸连接装置,所述可拆卸连接装置可与通信终端盒配套使用,其可与通信终端盒连接,通信终端盒可包括光缆接头盒、电缆接头盒、其他的光缆分纤箱和电缆分纤箱等,具体本申请不作限定。本申请中,所述可拆卸连接装置包括壳体、第一螺栓、卡持件和第一密封件。
其中,所述壳体包括第一端和第二端,所述壳体从所述第一端沿轴向延伸到所述第二端,在所述第一端端口的内壁设置第一螺纹,所述第一螺纹用于与所述第一螺栓螺纹连接;
所述卡持件设置在所述第一端的内壁轴向靠近所述第一螺纹处;
所述第一螺栓为中空结构;
套设在所述线缆上的所述第一螺栓用于在所述线缆插入所述壳体时,所述第一螺栓从所述第一端进入所述壳体,沿所述壳体的轴向移动,以使所述第一密封件沿所述卡持件的内周壁的导向沿朝向所述第二端的方向移动,所述第一密封件伸入所述卡持件内的部分产生形变,使得所述第一螺栓通过所述第一密封件与所述第一螺纹锁紧,以使所述线缆密封固定在所述壳体的内壁。

在一些可能的设计中,所述卡持件设置于所述第一端的内壁且向所述第二端延伸,可
选的,所述壳体与所述卡持件可拆卸连接,这样便于拆卸,也可根据线缆的轴向剖面形状来选择合适的卡持件,本申请中的卡持件可以配备多个,与壳体搭配使用。本申请中,卡持件包括第一端和第二端,卡持件的第一端的口径与卡持件的第二端的口径不相等,卡持件的第一端朝向所述壳体的第二端,所述第二端朝向所述壳体的第一端,卡持件的第一端至少能够容纳线缆通过。卡持件可为弹性材料,在插入线缆且第一螺栓锁紧过程中,该卡持件可产生形变,以加强线缆的密封固定。
可选的,本申请中的卡持件内壁的形状可多变,例如可以是任意形状的曲面,也可以是圆锥形状的曲面或者长方体形状的曲面等,具体可根据线缆的轴向剖面形状来设定。例如所述卡持件可包括曲面,曲面的曲率随着曲面的延伸方向递增,所述曲面的延伸方向为从所述第一端沿轴向到所述第二端的方向。一般情况下,卡持件可采用圆锥曲面,可直接在壳体的内壁做出一个向内凸出的锥形内腔,以形成一个卡持件。或者卡持件也可以是单独的部件,可安装于壳体内壁,在壳体内壁可设置卡槽,用于固定卡持件。
例如所述卡持件的曲面可以为楔形圆锥曲面或者扇形曲面,该楔形圆锥曲面可包括第一端和第二端,第一端的口径与第二端的口径不相等,所述第一端朝向所述壳体的第二端,所述第二端朝向所述壳体的第一端,此外,该第一端至少能够容纳线缆通过,对于第一端的口径大小可灵活设置。可见,采用楔形圆锥曲面或者扇形曲面能够更好的适应线缆的插入,也能够为第一密封件被机械性的挤压到曲面中提供较好的导向,当然也能够带来更好的密封性能。
在一些可能的设计中,所述线缆包括加强芯结构,例如为进一步的加固光缆内的光纤或者加固电缆内的电线,所述可拆卸连接装置还可包括第一螺钉和第一螺母。
所述第一螺母用于在所述线缆插入所述壳体时,在所述第二端与穿透所述加强芯结构的所述第一螺钉螺纹连接,所述加强芯结构位于所述第一螺母和所述第一螺钉之间。
可选的,在所述壳体的第二端还可预留一个穿尼龙扎带的位置,在固定好线缆的加强芯结构后,还可进一步用扎带对线缆进行绑扎固定。
在一些可能的设计中,考虑到线缆的横截面形状可能不同,本申请中还可根据线缆的横截面形状来对应配套的设计第一密封件的结构,可以设置所述第一密封件的内壁形状与所述线缆的横截面形状匹配,这样就可以适应各种形状的线缆的密封与固定的场景了。
在一些可能的设计中,对于多缆的安装场景,可以将第一密封件设置为多孔结构,其中每个孔都可容纳线缆通过,本申请不对第一密封件内开设的孔的数量进行限定,只要能够与要安装的线缆直径匹配即可,第一密封件内的各孔的口径可以相同或不同,以适配各种不同直径的线缆,具体可跟实际需求来设置,本申请不作限定。
在一些可能的设计中,本申请中的第一密封件还可为可拆卸结构,例如可以打开放入线缆,不需要将线缆穿过第一密封件,可见这种可拆卸结构可适用于直通缆的密封和固定,这样可以有效的提高安装效率。
在一些可能的设计中,所述可拆卸连接装置还包括与所述壳体外壁匹配的第二密封件,所述第二密封件用于将已安装所述线缆的所述可拆卸连接装置与所述通信终端盒连接时,与所述可拆卸连接装置相互插设连接,以使所述第二密封件与所述通信终端盒的内壁通过过盈配合方式密封连接。通过第二密封件,可进一步加强可拆卸连接装置与通信终端盒的
密封与固定。
在一些可能的设计中,所述壳体的第二端外壁上靠近所述第二密封件处设置弹性卡扣,所述弹性卡扣用于当已安装所述线缆的所述可拆卸连接装置与通信终端盒连接时,与所述通信终端盒的内壁形成倒扣,以使所述第二密封件与所述通信终端盒的内壁密封连接。可见,通过这种倒扣的方式能够对可拆卸连接装置和壳体的固定进一步加强,也方便机械拆卸。
在一些可能的设计中,所述第一螺栓的一端设置有固定结构,所述线缆穿透所述第一螺栓时,所述固定结构与所述线缆相抵持,使得所述固定结构抑制所述线缆与所述可拆卸连接装置之间的相对移动。通过设置该固定结构,一方面能够通过增大摩擦因素来便于用户旋紧,另一方面还可进一步的防止线缆松动。
本申请第二方面还提供一种通信终端盒,该通信终端盒包括进缆孔和前述第一方面以及第一方面中的各种可能的设计中任一所述的可拆卸连接装置。
本申请第三方面还提供一种壳体,所述壳体包括第一端和第二端,所述壳体从所述第一端沿轴向延伸到所述第二端,在所述第一端端口的内壁设置第一螺纹,在所述第一端的内壁轴向靠近所述第一螺纹处设置卡持件。
在一些可能的设计中,所述卡持件设置于所述第一端的内壁且向所述第二端延伸。
在一些可能的设计中,所述卡持件包括曲面,曲面的曲率随着曲面的延伸方向递增,所述曲面的延伸方向为从所述第一端沿轴向到所述第二端的方向。通过设置曲面的曲率随着曲面的延伸方向递增,能够为插入壳体1的部件提供导向,也可对插入壳体1的部件进行机械性的挤压,例如,将线缆插入壳体时,需要使用密封件来对线缆进行固定和密封,那么通过该曲面的导向,能够使得密封件在进入该曲面过程中,能够被机械性的挤压,使得密封件起到的密封作用更强。
可选的,所述曲面为楔形圆锥曲面或者扇形曲面。例如对插入壳体的线缆进行密封时,采用楔形圆锥曲面或者扇形曲面能够更好的适应线缆的插入,也能够为密封件被机械性的挤压到曲面中提供较好的导向,当然也能够带来更好的密封性能。
相较于现有技术,本申请提供的方案中,可拆卸连接装置包括壳体、第一螺栓、第一密封件,所述壳体的第二端的内壁设置卡持件和第一螺纹;通过这种结构,可以实现在线缆插入所述壳体时,通过第一螺栓沿所述壳体的轴向移动,使得第一密封件沿所述卡持件向第二端的方向移动,第一密封件伸入所述卡持件内的部分产生形变,使得所述第一螺栓通过所述第一密封件与所述第一螺纹锁紧,最终使得线缆密封固定在壳体的内壁。通过该种结构,能够对插入的线缆进行固定和密封,并且该种结构可以重复开启,便于拆卸,相较于现有机制,能够简化安装和提高安装效率。

需要说明的是,本申请中的光纤插头也可以是电缆插头等类似的结构,本申请还可用于室外电缆密封与固定插头,只需将光缆换成相应的电缆即可,当然也还可以应用到其他任意需要密封线缆的场景中,相应的,光缆接头盒也可替换为电缆接头盒,具体的应用场景本申请均不作限定。
请参照图1,以下对本申请提供一种用于密封线缆的可拆卸连接装置,所述可拆卸连接装置可与通信终端盒配套使用,其可与通信终端盒连接,所述可拆卸连接装置包括壳体1、第一螺栓2、第一密封件3和卡持件11。
所述壳体1包括第一端13和第二端14,所述壳体1从所述第一端13沿轴向延伸到所述第二端14,在所述第一端13端口的内壁设置第一螺纹12,所述第一螺纹12用于与所述
第一螺栓2螺纹连接。
所述卡持件11设置在所述第一端13的内壁轴向靠近所述第一螺纹12处。
所述第一螺栓2为中空结构。
套设在所述线缆上的所述第一螺栓2用于在所述线缆插入所述壳体1时,所述第一螺栓2从所述第一端13进入所述壳体1,沿所述壳体1的轴向移动,以使所述第一密封件3沿所述卡持件11的内周壁的导向沿朝向所述第二端14的方向移动,所述第一密封件3伸入所述卡持件11内的部分产生形变,使得所述第一螺栓2通过所述第一密封件3与所述第一螺纹12锁紧,以使所述线缆密封固定在所述壳体1的内壁。
相较于现有技术,本申请提供的方案中,通过采用上述的这种结构,可以实现在线缆插入所述壳体1时,通过第一螺栓2沿所述壳体1的轴向移动,使得所述第一密封件3沿所述卡持件11向第二端13移动,第一密封件3伸入所述卡持件11内的部分产生形变,使得所述第一螺栓2通过所述第一密封件3与所述第一螺纹12锁紧,最终使得线缆密封固定在壳体1的内壁。通过该种结构,能够对插入的线缆进行固定和密封,并且该种结构可以重复开启,便于拆卸,不需要电源驱动,只需简单的螺丝刀即可操作,安装场景不受限制,并且接入线缆时不需要反复翻转通信终端盒,因此,相较于现有机制,能够简化安装和提高安装效率。
可选的,在一些发明实施例中,所述卡持件11设置于所述第一端13的内壁且向所述壳体1的第二端14延伸,所述壳体1与所述卡持件11可拆卸连接,这样便于拆卸,也可根据线缆的轴向剖面形状来选择合适的卡持件,本申请中的卡持件11可以配备多个,与壳体1搭配使用。
在一些实施方式中,上述卡持件11包括第一端和第二端,卡持件11的第一端的口径与卡持件11的第二端的口径不相等,卡持件11的第一端朝向所述壳体1的第二端,所述第二端朝向所述壳体1的第一端,卡持件11的第一端至少能够容纳线缆通过。卡持件11可为弹性材料,在插入线缆且第一螺栓2锁紧过程中,该卡持件11可产生形变,以加强线缆的密封固定。
一些实施方式中,本申请中的卡持件11内壁的形状可多变,例如可以是任意形状的曲面,也可以是圆锥形状的曲面或者长方体形状的曲面等,具体可根据线缆的轴向剖面形状来设定。例如所述卡持件11可包括曲面,所述曲面与所述第一端13的内壁,曲面的曲率随着曲面的延伸方向递增,所述曲面的延伸方向为从所述第一端13沿轴向到所述第二端14的方向。通过设置曲面的曲率随着曲面的延伸方向递增,使得第一密封件在进入该曲面过程中,能够有效的对第一密封件进行机械性的挤压,使得第一密封件起到的密封作用更强。一般情况下,卡持件11可采用圆锥曲面,可直接在壳体1的内壁做出一个向内凸出的锥形内腔,以形成一个卡持件。或者卡持件11也可以是单独的部件,可安装于壳体内壁,在壳体内壁可设置卡槽,用于固定卡持件11。
下面以所述卡持件11的曲面可为楔形圆锥曲面或者扇形曲面,下面以楔形圆锥曲面11为例,如图4所示的侧剖图,该楔形圆锥曲面11包括第一端111和第二端112,第一端111的口径与第二端112的口径不相等,所述第一端111朝向所述壳体1的第二端14,所述第二端112朝向所述壳体1的第一端13,此外,该第一端111至少能够容纳线缆通过,对于
第一端111的口径大小可灵活设置。可见,采用楔形圆锥曲面或者扇形曲面能够更好的适应线缆的插入,也能够为第一密封件被机械性的挤压到曲面中提供较好的导向,当然也能够带来更好的密封性能。
一种实施方式中,可设第二端112的口径大于第一端111的口径,具体二者的口径差值可根据壳体1的内壁直径、线缆的轴向剖面形状和大小等参数灵活设置,本申请不对第一端111的口径和第二端112的口径大小、二者的口径差值,以及整个楔形圆锥曲面11的轴向长度均不作限定。当插入线缆时,第一螺栓2从楔形圆锥曲面11的第二端112伸入所述壳体1的第二端14的内壁,延楔形圆锥曲面11的第一端向第二端112移动,这样,套设在第一螺栓2上的第一密封件3会收到楔形圆锥曲面11的第二端112径向的抱紧力作用,即可约束第一密封件3的直径,使其不断缩小,最后能紧紧的与穿过的线缆抱紧在一起,最终完成线缆的密封,然后将密封好的可拆卸连接装置与通信终端盒连接,连接后的结构示意图可参考图5。
可选的,在一些发明实施例中,本申请中的所述线缆可包括加强芯结构,加强芯结构是用于加强线缆的强度,保护光缆内部的光纤或者电缆内部的电线不折断。为进一步的加固线缆,所述可拆卸连接装置还可包括第一螺钉4和第一螺母5,具体结构可参考图3和图示。本申请中,所述第一螺母5可用于在所述线缆插入所述壳体1时,在所述第二端14与穿透所述加强芯结构的所述第一螺钉4螺纹连接,所述加强芯结构位于所述第一螺母5和所述第一螺钉4之间。例如,线缆进入所述壳体1后,在所述壳体1的第二端14,可将加强芯结构放在第一螺母5上,然后用上述第一螺钉4压紧该加强芯结构,就可以达到固定加强芯结构的目的。
可选的,在所述壳体1的第二端14还可预留一个穿尼龙扎带的位置,在固定好线缆的加强芯结构后,还可进一步用扎带对线缆进行绑扎固定。
由通过分别在壳体1的第一端13和第二端14分别固定线缆,以及在壳体1的第一端对线缆进行密封,这样通过双重固定加上密封的方式,能够有效的避免线缆松动或者密封性能较差的问题。
可选的,在一些发明实施例中,考虑到线缆的横截面形状可能不同,本申请中还可根据线缆的横截面形状来对应配套的设计第一密封件3的结构,只要实现所述第一密封件3的内壁形状与所述线缆的横截面形状匹配即可。举例来说,如图7所示的蝶形缆,蝶形缆的截面为“8”字形,其两侧各有一道细小的沟槽,所以,在可拆卸连接装置内密封线缆时不能用前述实施例中的第一密封件3来进行密封。那么,可以对应的将第一密封件3的内部结构设置为如图8所示的“8”字形结构,第一密封件3的外壁形状不变,依然与壳体1的内壁形状配合。采用图8所示的结构后,即可通过楔形圆锥曲面11的压缩对线缆进行密封和固定,图8中所示的第一密封件的内孔是与蝶形缆横截面的形状及尺寸匹配的“8”字形通孔,这样便可以解决蝶形缆在可拆卸连接装置内的密封问题。
例如第一密封件3可为图3中的横截面为O型的O型密封圈3,该O型密封圈3可套设在第一螺栓2上,由于在第一螺栓2的拧紧过程中,该O型密封圈会连同第一螺栓2一同沿楔形圆锥曲面11移动,由于是从楔形圆锥曲面11的第二端112移动至楔形圆锥曲面11的第一端111,而第一端111的口径小于第二端112的口径,所以,在第一螺栓2和O
型密封圈3共同在楔形圆锥曲面11移动时,该O型密封圈3会被楔形圆锥曲面11挤压,从而收缩且与楔形圆锥曲面11紧密接触,并且该O型密封圈3上也会挤压出螺纹,使得第一螺栓2与第一螺纹12锁紧的更稳固,并且锁紧后能够达到密封的效果。
可选的,在一些发明实施例中,对于多缆的安装场景,可以将第一密封件3设置为多孔结构,其中每个孔都可容纳线缆通过,本申请不对第一密封件3内开设的孔的数量进行限定,只要能够与要安装的线缆直径匹配即可,第一密封件3内的各孔的口径可以相同或不同,以适配各种不同直径的光缆,具体可跟实际需求来设置,本申请不作限定。
在一些实施方式中,本申请中的第一密封件3还可为可拆卸结构,例如可以打开放入线缆,不需要将线缆穿过第一密封件3,可见这种可拆卸结构可适用于直通缆的密封和固定,这样可以有效的提高安装效率。本申请中的第一密封件3为可为单孔或多孔结构,本申请主要以单孔结构为例,其支持可拆卸的打开/闭合功能,第一密封件3闭合时所形成的内壁与线缆的轴向剖面形状匹配。
由本可选的实施例可知,采用本申请的可拆卸连接装置能够解决现有的机械密封和凝胶密封方式中,在入户光缆或电缆引入时单孔多缆所导致不能单缆管理的问题,采用本申请的可拆卸连接装置能够为通信终端盒或电缆接头盒的扩容的便利性,也便于对各光缆或电缆进行维护和管理。
本申请中的第一密封件3的可拆卸功能可以是通过在第一密封件3的一侧安装一个活动连接部件,以供打开和合上第一密封件3,也可以是直接在其上的开孔处设置一个口,以供线缆的放入。
可选的,在一些发明实施例中,为加强可拆卸连接装置与通信终端盒的密封与固定,还可设置第二密封件8。具体为:所述可拆卸连接装置还包括与所述壳体1外壁匹配的第二密封件8,所述第二密封件8用于将已安装所述线缆的所述可拆卸连接装置与所述通信终端盒连接时,与所述可拆卸连接装置相互插设连接,以使所述第二密封件8与所述通信终端盒的内壁通过过盈配合方式密封连接。可选的,该第二密封件也还可用于固定可拆卸连接装置和线缆,例如图9所示的线缆与可拆卸连接装置密封固定后的一种结构示意图。
其中,过盈配合方式是指具有过盈(包括最小过盈等于零)的配合。例如,相配对的轴径要大于孔径,然后采用工具挤压进去,或利用热涨冷缩的特性,将孔加热,趁孔径扩大,迅速套到轴上,待冷却收缩后二个零件就紧紧配合成一体。可见通过上述第二密封件,能够加强可拆卸连接装置与通信终端盒的密封与固定。
在一些实施方式中,为进一步防止线缆的松动,还可在可拆卸连接装置的壳体1上设置弹性卡扣或者卡勾等部件以达到闭锁的效果,并且可以从所述壳体1外部通过施加压力以脱开,从而可以轻松的分离可拆卸连接装置和通信终端盒,可见,本申请采用该弹性卡扣15能够实现不需要安装工具即可轻松的完成安装和拆卸的操作。具体来说,在本申请中,可在所述壳体1的第二端14外壁上靠近所述第二密封件8处设置弹性卡扣15,所述弹性卡扣15用于当已安装所述线缆的所述可拆卸连接装置与通信终端盒连接时,与所述通信终端盒的内壁形成倒扣,以使所述第二密封件8与所述通信终端盒的内壁密封连接。
可选的,在一些发明实施例中,为进一步防止线缆相对于所述壳体1的第一端的相对移动,所述第一螺栓2的一端还可设置有固定结构21,该固定结构21也可以是套设在第
一螺栓2上的结构,具体本申请不作限定。所述线缆穿透所述第一螺栓2时,所述固定结构21可与所述线缆相抵持,从而使得所述固定结构21抑制所述线缆与所述可拆卸连接装置之间的相对移动。通过设置该固定结构,一方面能够通过增大摩擦因素来便于用户旋紧,另一方面还可进一步的防止线缆松动。
可选的,该固定结构可留有线扎位,或者采用的金属压板,然后通过第一螺钉4锁紧,达到夹紧线缆的效果,从而避免线缆与可拆卸连接装置之间的相对移动,从而实现对线缆的固定。此外,还可在该固定结构21上设置对称的削平平面,削平平面内有沿轴向的浅沟槽,一方面可起到与线缆相抵持的效果,另一方面还可以增加操作手感。
需要说明的是,本申请不对第一密封件、第二密封件以及卡持件的数量和形状进行限定,具体的数量可根据加固要求、部署的线缆数量等因素选择,并且,本申请图1-图9中任一所对应的实施例中的共同部件的特征均适用于下述图10所对应的实施例,类似之处不作赘述。
本申请还提供一种通信终端盒,该通信终端盒包括前述图1-图9中任一所示的可拆卸连接装置,当将可拆卸连接装置插入通信终端盒后,可构成一个完整的通信终端盒,具体的结构可参考图5所示的结构。
本申请还提供一种壳体1,如图10所示,所述壳体1包括第一端11和第二端12,所述壳体1从所述第一端11沿轴向延伸到所述第二端12,在所述第一端11端口的内壁设置第一螺纹13,在所述第一端11的内壁轴向靠近所述第一螺纹13处设置卡持件14。
可选的,所述卡持件14设置于所述第一端11的内壁且向所述第二端12延伸,所述卡持件14可与壳体1可拆卸连接。这样便于拆卸,也可根据线缆的轴向剖面形状来选择合适的卡持件,本申请中的卡持件14可以配备多个,与壳体1搭配使用。
可选的,所述卡持件14包括曲面,所述曲面与所述第一端11的内壁,曲面的曲率随着曲面的延伸方向递增,所述曲面的延伸方向为从所述第一端11沿轴向到所述第二端12的方向。通过设置曲面的曲率随着曲面的延伸方向递增,能够为插入壳体1的部件提供导向,也可对插入壳体1的部件进行机械性的挤压,例如,将线缆插入壳体时,需要使用密封件来对线缆进行固定和密封,那么通过该曲面的导向,能够使得密封件在进入该曲面过程中,能够被机械性的挤压,使得密封件起到的密封作用更强。
可选的,所述曲面为楔形圆锥曲面或者扇形曲面。例如对插入壳体1的线缆进行密封时,采用楔形圆锥曲面或者扇形曲面能够更好的适应线缆的插入,也能够为密封件被机械性的挤压到曲面中提供较好的导向,当然也能够带来更好的密封性能。
该楔形圆锥曲面可包括第一端141和第二端142,第一端141的口径与第二端142的口径不相等,所述第一端141朝向所述壳体1的第二端12,所述第二端142朝向所述壳体1的第一端11,此外,该第一端141至少能够容纳要密封的产品通过,对于第一端141的口径大小可灵活设置。
在一些发明实施例中,所述壳体1的第二端12的外壁或内壁可预留孔位或者其它形状的结构,可用于扩展该壳体1的结构,具体实施方式本申请不作限定。
本申请中的可拆卸连接装置可以是独立于通信终端盒之外的装置,也可以是通信终端盒的组成部件,且可拆卸连接装置能够直接与通信终端盒通信连接,也可通过其它转接部
件来实现通信连接,具体本申请不作限定。
