交叉引用
本申请主张2016年3月7日提交的中国专利申请号为201610127714.8的优先权，其全部内容通过引用包含于此。
技术领域
本发明涉及视听设备领域，尤其涉及一种电视机主板装置、连接装置、电视机及电视机系统。
背景技术
传统电视机主板一般集成在电视机后壳中。图1a示出了现有技术中电视机主板及其与电视机内其他相关部件连接关系的示意图。在图1a中，电视机主板集成在电视机后壳中，220V电源电力通过电源线输入到电视机内的电源板，电源板将一部分电源电力转换成12V直流电为电视机主板供电，将另一部分转换成灯条驱动电压供给背光灯条以点亮屏幕。电视机主板输出处理后的多媒体信号并传送到后续部件，例如控制屏体显示的时序控制器T-CON。
图1b示出了现有技术中集成有电视机主板的电视机的后视图。
可以看出，现有技术将电视机主板集成在电视机后壳中，由于主板外接端口多，将导致电视机后壳需引出很多外接设备线(例如参见图1b)，既影响美观，也不方便外接设备的安装和摆放。此外，这样的电视机主板不方便拆卸和替换，一旦电视机主板损坏或需要更新换代，可能只能更换整个电视机。
对此，现有技术中提出了将电视机主板作为一个独立的装置，设置于电视机机壳之外的方案。然而这样一来，电视机和主板分别都需要供电线路， 又需要将电视机和主板相连的线路，线路繁杂，导致使用和安装仍然不便，外观也不够简洁美观。
