本发明的较佳实施方式
以下是对本文详细描述的主题的概述。本概述并非是为了限制权利要求的保护范围。
为了解决相关技术中，户外设备尺寸减小与接口增多存在着矛盾，限制了户外设备的尺寸的问题，本发明提供了一种户外设备对外接口防护装置，以下结合附图以及实施例，对本发明进行进一步详细说明。应当理解，此处所描述的具体实施例仅仅用以解释本发明，并不限定本发明。
本发明实施例提供了一种户外设备对外接口防护装置，该装置的结构示意如图1所示，包括：
多线缆保护套1，线缆密封圈2(图中未示出，在迫紧螺母3内)和迫紧螺母3；
其中，线缆密封圈2，设置在多线缆保护套1之后，进行线缆的过线以及防水；
迫紧螺母3，设置在线缆密封圈2之后，与线缆密封圈2共同作用，锁紧多线缆保护套1的尾部。
本发明实施例提供的户外设备对外接口防护装置具有多线缆保护套，能够容纳多根线缆，使户外设备上的原来的多根线缆可以通过一个法兰对外，并通过线缆密封圈和迫紧螺母将该保护套锁紧，该装置能够将原来的多接口对外方式转变为单接口对外，解决了相关技术中，户外设备尺寸减小与接口增多存在着矛盾，限制了户外设备的尺寸的问题。
在实施过程中，上述装置还可以如图2所示，其中的多线缆保护套包括：内套筒11和外护套12，其中，内套筒11包括：与法兰4连接的卡扣、防水密封圈以及尾部的束紧卡爪；外护套12，设置在内套筒外侧，保护内套筒。进一步，多线缆保护套1与法兰4连接的孔径大小可以设置为能够容纳多根线缆的尺寸。
当户外设备对外接口防护装置中束紧卡爪处的过线孔的数量多于线缆的数量时，会造成一些过线孔闲置，则还可以为内套筒的束紧卡爪处的过线孔设置堵头，与过线孔配合使用，在束紧卡爪的过线孔闲置时，堵住过线孔。
可选地，为了防止多个线缆从一个孔与外界连接造成的线缆堆积在一块的问题，还可以在多线缆保护套中增加一个限位卡板，设置在内套筒11之后，外护套12之前，与内套筒11紧密连接，受外护套12保护，对多根线缆的位置进行固定限位。通过上述限位卡板，可以将多线缆的位置进行固定，并能够良好的对多线缆进行散热。本领域技术人员在设置时，可以根据需求将上述限位卡板设置为双线限位卡板或四线位卡板等。
设置时，线缆密封圈2的尺寸根据线缆的尺寸进行匹配设计，材质为具有弹性的材料，这样能够很好的实现对线缆的防水，充分保护线缆。
在具体连接时，内套筒11直接与机壳上的法兰相连，内套筒11上的卡扣与密封圈2分别实现内套筒11与机壳的锁紧与密封；外护套12安装在内套筒11的外表面，保护内套筒11。在实际产品中，随着迫紧螺母3的锁紧，外护套12会受力并移动到内套筒11上合适的位置；线缆密封圈2有弹性，用于线缆过线以及密封，完整装配以后将置于内套筒11的尾部卡爪处，过线孔闲置时，有配套的堵头堵住过线孔；迫紧螺母3用以锁紧护套的尾部，实 现防护。
安装时，先将多根线缆组件穿过防护套，然后将线缆组件上的连接器与设备上的相应接口可靠连接，紧接着将内套筒与一体化法兰锁紧，然后将限位卡板卡在线缆上，并移动至外护套的尾部内，最后锁紧外护套尾部的迫紧螺母实现对接口的防护。外护套会在迫紧螺母的作用下滑动至内套筒上，实现对内护套的防护。
采用本发明的装置，与相关技术相比，取得了通用化强，配置简单的进步，可以兼容不同种类、不同数量线缆配置，适应未来户外无线设备的体积小、接口多的特点。
优选实施例一
无线射频拉远单元(Radio Remote Unit，简称为RRU)系统中用的户外基站是一种非常重要的组成部分，它主要的作用是射频信号的处理、发送和接收。通常情况下，RRU会被安装在靠近天线的室外环境中，通过RRU上带防护的对外接口来实现RRU与基带处理单元(Building Base band Unit，简称为BBU)、RRU与天线等设备的互联。
随着无线通信系统的不断发展，RRU的体积不断缩小，而RRU上的对外接口需求却日益增多，尤其是光口的需求量越来越大，传统的单光口排布已不能满足使用要求，于是在大容量小体积的场景下将更多的采用双光口排布，随之将带来是双光缆组件的连接以及防护问题。因此，本发明优选实施例针对的线缆是双光纤线缆，提供的户外设备对外接口防护装置如图3所示，包括：
A、内套筒，包括与法兰F连接的卡扣、密封圈以及尾部的束紧卡爪；
B、双线卡板(即具有两个孔的限位卡板)；
C、外套筒(即外护套)，用以保护内套筒；
D、双孔过线塞(即具有两个孔的线缆密封圈)；
E、尾部迫紧螺母。
A直接与机壳上的法兰F相连，A上的卡扣与密封圈分别实现A的机壳的锁紧与密封；B于抗拉模块的尾部卡住两根光纤G，完整装配以后还将倚 住C内部的小台阶，防拉脱；C安装在A的外表面，保护A，在实际产品中，C和A是一体的，不需要独立安装；D有弹性，用于两根光缆过线以及防水，完整装配以后将置于A的尾部卡爪处，过线孔闲置时，有配套堵头堵住过线孔；E为迫紧螺母用以锁紧护套的尾部，实现防水，安装好的示意如图4所示，双光纤穿过整个保护套，保护套(该保护套是A和C组成的整体，由于A和C的位置关系，图4中仅能示出外套筒C)与法兰F紧密连接，实现了对双光纤G的保护。
下面对技术方案的实施作进一步的详细描述，安装步骤如下：
取下B和D，使两根光缆组件穿过整个防护套；将两根光缆组件的光连接器与光模块连接好；安装B，使之在光缆组件抗拉模块的尾端卡住两根光缆；用防护套的卡扣锁住法兰的卡槽，使之紧密连接；用过线塞卡住两根光缆并移动过线塞至防护套内，使过线塞尾端与A的尾端齐平；拧紧E，使得光缆与过线塞紧密贴合，实现防水；此装置兼容单光纤出线配置，在此状态下，需要将闲置的过线孔用设计好的堵头堵上，防止进水。
采用本发明的装置，与相关技术相比，取得了通用化强，配置简单的进步，双光纤与单光纤配置兼容的效果，将单个对外接口的出线能力提升一倍，适应未来RRU的体积小、接口多的特点。
优选实施例二
本发明优选实施例针对的线缆是五线缆，提供的户外设备对外接口防护装置包括：
内套筒A，包括与法兰F连接的卡扣、密封圈以及尾部的束紧卡爪；外套筒C(即外护套)，用以保护内套筒；五孔过线塞D(即具有五个孔的线缆密封圈)；尾部迫紧螺母E。
内套筒A直接与机壳上的法兰F相连，内套筒A上的卡扣与密封圈分别实现内套筒的机壳的锁紧与密封；外套筒C安装在内套筒A的外表面，保护内套筒A，在实际产品中，外套筒C和内套筒A是一体的，不需要独立安装；五孔过线塞D有弹性，用于五根线缆W过线以及防水，完整装配以后将置于内套筒的尾部卡爪处，过线孔闲置时，有配套堵头堵住过线孔；尾部迫紧螺 母E为迫紧螺母用以锁紧护套的尾部，实现防水，安装好的示意如图5所示，五线缆W穿过整个保护套，保护套(该保护套是A和C组成的整体，由于A和C的位置关系，图5中仅能示出外套筒C)与法兰F紧密连接，实现了对五线缆W的保护。由于图中是侧视图，因此，五根线缆W的位置和结构可能存在未被完全示出的情况。
下面对技术方案的实施作进一步的详细描述，安装过程如下：取下五孔过线塞，使五根线缆穿过整个防护套；用防护套的卡扣锁住法兰的卡槽，使之紧密连接；用过线塞卡住五根线缆并移动过线塞至防护套内，使过线塞尾端与内套筒的尾端齐平；拧紧尾部迫紧螺母，使得线缆与过线塞紧密贴合，实现防水。
在阅读并理解了附图和详细描述后，可以明白其他方面。
尽管为示例目的，已经公开了本发明的优选实施例，本领域的技术人员将意识到各种改进、增加和取代也是可能的，因此，本发明的范围应当不限于上述实施例。
工业实用性
