为了使本申请的技术方案及优点更加清楚明白，以下结合附图及实施例，对本申请进行进一步详细说明。应当理解，此处描述的具体实施例仅仅用以解释本申请，并不用于限 定本申请。
在一个实施例中，如图1与图2所示，提供了一种LED显示屏，包括箱体100与灯板600，以及设置于箱体100内的转换器200、插头300与转接板400，箱体100与灯板600连接；插头300的第一端与转换器200的输入端活动连接，第二端与外部电源电连接，转接板400的一端与转换器200的输出端活动连接，另一端与灯板600活动连接；转换器200用于将外部电源输入的交流信号转换为直流信号。
具体地，插头300将外部电源提供的交流信号传输至转换器200。转换器200可将外部电源输入的交流信号转换为直流信号，并通过转接板400传输至灯板600，用于给灯板600进行供电显示。其中，转换器200与插头300、转换器200与转接板400以及转接板400与灯板600之间均为活动连接，可以是通过搭接的方式，也可以是通过插接的方式。例如通过螺钉锁合的方式连接，或者是通过插针与母针插接的方式连接。活动连接的方式可实现LED显示屏内部的无线电连接，有效提升LED显示屏内部整洁度的同时，有效提高各部件之间电连接的可靠性。
转换器200与插头300之间的连接方式并不唯一，在一个实施例中，插头300的第一端通过搭接的方式与转换器200的输入端连接。
在一个实施例中，如图3所示，并参考图1及图2，插头300的第二端340设有三线插头，用于与外部电源电连接。具体地，外部电源可以是380V的交流市电，插头300的第二端340的三线插头可连接市电接入交流信号并传输至其第一端320。
在一个实施例中，如图3与图4所示，插头300的第一端320设有三个翅片322，转换器200的输入端设有三个台阶220，三个翅片322分别搭接于转换器200对应的台阶220，用于交流信号的传输及接地。
具体地，由于插头300用于将外部电源输入的交流信号传输至转换器200，则其第一端320设置的三个翅片322可分别对应连接外部电源的火线L、零线N与地线E，并将其信号传输至对应搭接的台阶220。可以理解，其中分别连接火线L与零线N的两个翅片322与台阶220用于交流信号的传输，连接地线E的翅片322与台阶220用于接地。
进一步地，翅片322与台阶220对应连接的方式并不唯一，在一个实施例中，插头300的三个翅片322与转换器200对应的台阶220通过螺钉锁合的方式固定连接。
在另外的实施例中，如图3所示，插头300还包括第三端360，第三端360上设有三线插孔，用于与外部设备连接并输出交流信号。具体地，第三端360的三线插孔与第二端340的三线插头具有对应的结构，可以理解为将第二端340从市电接入的交流信号直接进行输出。
另外，插头300的实际采用的硬件并不唯一，在一个实施例中，插头300为注塑一体航插。
对应地，转换器200与转接板400以及转接板400与灯板600之间的连接方式也并不唯一，在一个实施例中，转接板400的一端与转换器200的输出端通过搭接或插接的方式活动连接，转接板400的另一端与灯板600通过搭接或插接的方式活动连接，实现了LED显示屏内部器件的无线电连接。
在一个实施例中，如图4所示，并参考图1及图2，转换器200的输出端设有至少一个母针240，用于与转接板400活动连接。
具体地，转换器200在接入交流信号后，可将交流信号转换为直流信号。则转换器200的输出端设置有两个母针240，分别对应为正极输出V+与负极输出V-，用于将直流信号通过转接板400传输至灯板600。其中，转换器200的输出端设置的母针240的类型并不唯一，在本实施例中，均采用Pogoing母针。
在一个实施例中，如图5所示，并参考图1及图2，转接板400靠近转换器200的一面设有至少一个插针420，插针420与母针240对应通过插接的方式活动连接。可以理解， 插针420的数量需与母针240的数量相匹配，对应插接至母针240后实现直流信号的传输。
在一个实施例中，参考图1及图2，上述LED显示屏还包括安装于箱体100内的后壳500，转接板400与灯板600分别固定安装与后壳500的两侧。具体地，后壳500呈板状，用于对转接板400与灯板600进行固定。

在一个实施例中，如图5所示，并参考图1及图2，转接板400靠近后壳500的一面设有第一连接器440，用于与灯板600活动连接。具体地，第一连接器440的数量并不唯一，可以是一个，也可以是两个，还可以是三个以上，具体可根据灯板600的大小设定。例如，在本实施例中，第一连接器440的数量为4个。
在一个实施例中，参考图1及图2，后壳500设有通孔520，转接板400的第一连接器440穿过后壳500的通孔520与灯板600活动连接。可以理解，通孔520的数量与尺寸均需根据第一连接器440确定，对应设置于转接板400的第一连接器440在后壳550上的投影位置，进而实现第一连接器440穿过后壳500的通孔520与灯板600活动连接。
在一个实施例中，如图2所示，灯板600设有与第一连接器440对应匹配的第二连接器620。可以理解，第二连接器620的数量与尺寸需根据第一连接器440确定，对应连接后实现转接板400与灯板600的无线电连接。
第一连接器440与第二连接器620的具体结构并不唯一，在一个实施例中，第一连接器与第二连接器均为浮动连接器。具体地，第一连接器440与第二连接器620均为4+60P浮动连接器。
在一个实施例中，参考图1及图2，箱体100与灯板600通过磁吸的方式连接。具体地，在箱体100对应灯板600的卡件640的位置上，设置有磁铁。对应地，卡件640的材料为具有磁性的金属卡件，例如铁质卡件、镍质卡件或铬质卡件等，以实现箱体100与灯板600的磁吸连接。
以上实施例的各技术特征可以进行任意的组合，为使描述简洁，未对上述实施例中的各个技术特征所有可能的组合都进行描述，然而，只要这些技术特征的组合不存在矛盾，都应当认为是本说明书记载的范围。
以上所述实施例仅表达了本申请的几种实施方式，其描述较为具体和详细，但并不能因此而理解为对申请专利范围的限制。应当指出的是，对于本领域的普通技术人员来说，在不脱离本申请构思的前提下，还可以做出若干变形和改进，这些都属于本申请的保护范围。因此，本申请专利的保护范围应以所附权利要求为准。
