可插拔设备
本申请要求于 201 3年 7月 1 5日提交中国专利局、 申请号为
2 01 31 0302442. 7 、 发明名称为 "可插拔设备" 的中国专利申请的优先权, 其全部内容通过引用结合在本申请中。
技术领域
本发明涉及通信技术领域， 特别涉及一种可插拔设备。 背景技术 ASS (Active Antenna System,有源天线系统)是将传统基站系统的 RF ( Radio
Frequency, 射频）直连天线振子， 集成在天线中， 从而减少了天线到 RF或 RRU ( Radio Remote Unit, 射频拉远单元）的馈线以及天线内部的功率分配网络， 降 低了基站系统功耗。 但是在 RF与天线振子直连时， 天线反射板的投影面积决定 了 AAS系统的长宽尺寸， 要在这个有限的面积布局完整的射频电路， 需要采用 空间层叠板的方式。 空间层叠板的方式是通过多个连接器在多层板间做信号接 力实现的， 这样就导致多个连接器占据较大的 PCB ( Printed Circuit Board , 印制 电路板）布板面积， 同时为适应多个板间器件的高度， 必须选用高度适合的连 接器， 导致连接器设计上不灵活， 成本高。
现有技术中， 可以通过金手指连接器解决上述问题。 金手指连接器由众多 金属导电触片组成， 所有的信号通过金属导电触片进行传输， 将该金属导电触 片俗称为金手指。 该金手指连接器可以随 PCB的制作一起完成， 使得金手指连 接器的尺寸与板件器件匹配， 设计灵活， 且价格低廉。
在实现本发明的过程中， 发明人发现现有技术至少存在以下问题： 对于金手指连接器来说， 由于金手指均具有一定的高度， 金手指接触的高 度方向上具备容差能力。 而由于金手指连接器可以随 PCB的制作一起完成， 其 在 PCB板上的位置固定， 一旦有 PCB板插入金手指连接器， PCB板之间的相 对位置不能够发生变化， 也即是金手指连接器在水平方向上不具备容差能力。 发明内容

结合第一方面， 在第一方面的第二种可能实现方式中， 至少一个金手指连 接器位于所述金手指背板的同一面， 或至少一个金手指连接器分别位于所述金 手指背板的正面和背面。
结合第一方面， 在第一方面的第三种可能实现方式中， 所述金属连接区域 为亮铜区或焊盘。
结合第一方面， 在第一方面的第四种可能实现方式中， 所述金属连接区域 的面积大于金属簧片的触点面积。
结合第一方面， 在第一方面的第五种可能实现方式中， 所述至少一个金属 连接区域位于所述金手指背板的同一面， 或所述至少一个金属连接区域分别位 于所述金手指背板的正面和背面。
结合第一方面， 在第一方面的第六种可能实现方式中， 所述金手指背板还 包括多个过孔。 结合第一方面， 在第一方面的第七种可能实现方式中， 至少两个金手指连 接区域中的任一个金手指连接区域用于与天线模块连接。 本发明实施例提供的技术方案带来的有益效果是：
通过在金手指背板上设置金属连接区域与 PCB上的金属簧片相连， 由于金 属簧片具有一定的弹性， 使得所述插拔设备能够适应不同 PCB间距的要求， 极 大的优化和利用空间。 附图说明
