附图说明
为了更清楚地说明本发明实施例或现有技术中的技术方案，下面将对实施例或现有技术描述中所需要使用的附图作一简单地介绍，显而易见地，下面描述中的附图是本发明的一些实施例，对于本领域普通技术人员来讲，在不付出创造性劳动的前提下，还可以根据这些附图获得其他的附图。
图1示出了本申请实施例一提供的调谐器单元模组的结构示意 图；
图2示出了本申请实施例二提供的调谐器的结构示意图。
具体实施方式
为使本发明实施例的目的、技术方案和优点更加清楚，下面将结合本发明实施例中的附图，对本发明实施例中的技术方案进行清楚、完整地描述，显然，所描述的实施例是本发明一部分实施例，而不是全部的实施例。基于本发明中的实施例，本领域普通技术人员在没有作出创造性劳动前提下所获得的所有其他实施例，都属于本发明保护的范围。
由于电子调谐器更新速度太快，更换新的调谐器，电视主板PCB走线需要重新规划，这样会造成很大的工作量，同时研发周期会比较长。另外，不同国家的射频制式不同，不同的需求导致主板PCB种类繁多，无法做到统一化，管理和成本都比较难管控。针对上述问题，本申请实施例一提供了一种调谐器单元模组。
实施例一
参见图1，本实施例提供的调谐器单元模组100包括至少一个调谐器芯片，所述调谐器单元模组具有第一预设数量的输入管脚和第二预设数量的输出管脚；
所述输入管脚用于与预设的射频接收单元的输出接口一一对应相连，所述输出管脚用于与预设的电视主板的输入接口一一对应相连。
图1中，管脚1-5属于输入管脚，用于与射频接收单元200相连；管脚6-13属于输出管脚，用于与电视主板300相连。
当图1中的调谐器单元模组中的调谐器芯片更换为另一种调谐器芯片时，该调谐器单元模组100中用于与射频接收单元200相连的输入管脚与射频接收单元200的输出接口的连接关系不变， 该调谐器单元模组100中用于与电视主板300相连的输出管脚与电视主板300的输入接口的连接关系不变。
本实施例所述的调谐器单元模组，由于具有统一的输入管脚和输出管脚，因此，当调谐器单元模组需要更新或改进时，只需更换其中的调谐器芯片即可，无需更换整个调谐器单元模组，因此也就无需制作适应新的调谐器单元模组的电视主板，从而节省了电视主板的设计成本和制作成本。
可选地，所述第一预设数量还可以为9，所述第二预设数量还可以为20。或者，可选地，所述第一预设数量还可以为12，所述第二预设数量还可以为22。或者，可选地，所述第一预设数量还可以为20，所述第二预设数量还可以为30。
可选地，所述调谐器芯片为全制式调谐芯片或半制式调谐芯片。当所述调谐器芯片为全制式调谐芯片时，由该调谐器单元模组组成的调谐器就可以适应全球不同的调谐制式。
同时，由于该述调谐器单元模组不论支持全制式调谐还是半制式调谐，与该调谐器单元模组适应的电视主板都是一致的。因此，不用再因为出口市场对射频需求的变化而重新设计或更改电视主板，因此节省了电视主板的设计和制作成本，同时也提高了效率。
另外，对于不同射频制式需求，由于电视主板的结构或走线均一致，因此可以对电视主板的设计和制作实现统一管理，进一步降低了成本。
为了提高调谐器单元模组对射频信号的调谐能力以及便于安装和存放，所述调谐器单元模组采用金属屏蔽外壳封装，所述输入管脚和输出管脚置于所述金属屏蔽外壳的外侧。
综上所述，本实用新型将调谐器单元模组固有化，因此在需要更换调谐器单元模组时，只需对其中的调谐器芯片进行更换， 并不改变调谐器单元模组的输入输出，因此与该调谐器单元模组适应的电视主板将不用再重新布线。
实施例二
本申请实施例二提供了一种调谐器，参见图2，该调谐器包括射频接收单元200和如上述实施例所述的调谐器单元模组100。
本实施例所述的调谐器的射频接收单元200将接收到的射频信号发送给调谐器单元模组100，由调谐器单元模组100中的调谐器芯片将射频信号调谐为中频信号发送给电视主板，由电视主板对该中频信号进行处理。
本实施例所述的调谐器由于包括上述实施例所述的调谐器单元模组，因此当需要更换该调谐器时，只需更换调谐器单元模组中的调谐器芯片即可，无需更改与该调谐器相适应的电视主板，即当调谐器更新时，电视主板将不用再重新设计、布线和生产，从而提高了效率，降低了成本。
实施例三
本申请实施例二提供了一种电子设备，该电子设备包括如上述实施例所述的调谐器。该电子设备可以为智能电视、显示器等等。
以上所描述的装置实施例仅仅是示意性的，其中所述作为分离部件说明的单元可以是或者也可以不是物理上分开的，作为单元显示的部件可以是或者也可以不是物理单元，即可以位于一个地方，或者也可以分布到多个网络单元上。可以根据实际的需要选择其中的部分或者全部模块来实现本实施例方案的目的。本领域普通技术人员在不付出创造性的劳动的情况下，即可以理解并实施。
最后应说明的是：以上各实施例仅用以说明本发明的实施例的技术方案，而非对其限制；尽管参照前述各实施例对本发明的 实施例进行了详细的说明，本领域的普通技术人员应当理解：其依然可以对前述各实施例所记载的技术方案进行修改，或者对其中部分或者全部技术特征进行等同替换；而这些修改或者替换，并不使相应技术方案的本质脱离本发明的实施例各实施例技术方案的范围。
