背景技术
为了便于生产制造，一般采用电路板拼板将多个小尺寸的电路板通过连接筋拼接成较大尺寸的电路板拼板以便于批量生产制造。然而，随着电子产品的轻薄化发展，电路板也被要求制造得越来越薄和越来越小，这样使得电路板拼板所拼接的电路板个数增多，从而造成电路板拼板的连接强度减弱，特别地，电路板设有避空区的地方无法设置连接筋，因此会进一步降低电路板拼板的连接强度，影响拼接式电路板后期的贴片效果。

具体实施方式
下面将结合本发明实施方式中的附图，对本发明实施方式中的技术方案进 行清楚、完整地描述。
请参考图1和图2，图1为本发明实施例提供的电路板拼板100，图2为图1中的两个电路板拼接的结构示意图。电路板拼板100包括板体1和异形筋2，板体1包括多个电路板10。异形筋2连接于相邻的两个电路板10之间，以固定连接多个电路板10。所述每一个电路板10包括相背设置的第一端A和第二端B，所述第一端A设有避空区域C，该避空区域C可以用于设置结构件D。为了便于描述，本申请将用电路板11、电路板12、电路板13区分不同的电路板10，并且用第一端A12表示电路板12的第一端，用第二端B11表示电路板11的第二端，用避空区域C12分别表示电路板12的避空区域。
请参阅图2，所述异形筋2包括第一固定端21a和第二固定端23a。当一个电路板11的第二端B11与另一个电路板12的避空区域C12拼接时，，异形筋2的第一固定端21a与第二固定端23a分别错位设置在一个电路板11的第二端B11和另一个电路板12的第一端A12，并且第二固定端23a跨过避空区域C12设置在避空区域C12的附近，提高电路板在避空区域C12的连接强度。
在本实施例中，板体1大致呈矩形状，其具有相对设置的两条第一长边L0、L1和相对设置的两条第一短边S0、S1，两条第一短边S0、S1分别连接于两条第一长边L0、L1之间。所述两条第一长边L0、L1相平行设置，及所述两条第一短边S0、S1相平行设置，且所述第一短边S0、S1的延伸方向与所述第一长边L0、L1的延伸方向相互垂直。
可以理解的，电路板10的数量根据实际所需而相应设置。拼接成板体1的电路板10的数量此处以六个举例。电路板10具有相对设置的第二长边L2和第三长边L3和相对设置的第二短边S2和第三短边S3，第二短边S2和第三短边S3分别连接于第二长边L2和第三长边L3之间。沿着所述第一短边S0方向延伸的两条第二长边L2拼接形成第一短边S0，沿着所述第一长边L0方向延伸的三条第二短边S2拼接形成第一长边L0。可以理解的，第二长边L2即电路板10的第一端A，第一端A开设矩形凹槽形成避空区域C，该避空区域C靠近第三短边S3。可以理解的，第一端A上除了避空区域C之外其它部位皆为避空区域C的外部。第三长边L3即电路板10的第二端B，第二端B的任何位置上皆可以设置异形筋2以与相邻的电路板10连接。一种实施方式中，各个电路板10的尺寸和结构相同。 当然，在其它实施例中，各个电路板10的尺寸或结构还可以相异。
其中，相邻两个电路板10拼接可以分为沿着第一短边S1延伸方向和沿着第一长边L1延伸方向的拼接。沿着第一短边S1相邻的两个电路板10的拼接为：一个电路板11的第三短边S3与另一个电路板13的第二短边S2拼接，该方式的拼接，由于第三短边S3和第二短边S2皆无设置避空区域C，故连接筋条不需要避让避空区域C，相邻的第三短边S3和第二短边S2的任意位置上皆可以设置连接筋条以实现拼接。沿着第一长边L1相邻的两个电路板的拼接为：一个电路板11的第二端B11与另一个电路板12的第一端A12拼接，由于电路板12的第一端A12上设置了避空区域C12，故异形筋2需要避让该避空区域C12，现有技术通常为相邻的两个电路板10对应该避空区域C的位置皆不设置筋条，使得电路板拼板100的连接强度较弱，不利于后期贴片效果。
在本实施例中，请参照图2，异形筋2包括第一固定端21a和第二固定端23a，该异形筋2主要针对相邻的两个电路板11、12拼接时，电路板12的拼接位置为避空区域c12，而无法在对应避空区域C12的位置设置筋条与另一个电路板11拼接的情况。具体的，为了便于描述，此处将一个电路板称为第一电路板11，另一个电路板称为第二电路板12，第一固定端21a固设于第一电路板11的第二端B11，第二固定端23a沿着远离第一固定端21a的方向延伸且跨过第二电路板12的避空区域C12，并且该第二固定端23a固定于第二电路板12的避空区域C12的外部。即第一固定端21a与第一电路板11的连接位置与第二固定端23a与第二电路板12的连接位置相互错开，其中，第二固定端23a还跨过第二电路板12的避空区域C12，使得第二电路板12的避空区域C12与所述第一电路板11之间有连接筋体固定连接，而实现了相邻两个电路板11、12在避空区域C处进行拼接，以提高相邻的两个电路板11、12在避空区域C12处的连接强度，从而提高了电路板拼板100整体的连接强度。
进一步的，请参照图2，所述第一固定端21a在第一端A12的正投影区域位于所述避空区域C12中。即第一固定端21a正对第二电路板12的避空区域C12，而第二固定端23a则固定于第二电路板12的避空区域C12的外部，这样使得避空区域C12与电路板11紧挨在一起，且异形筋2具有一定的连接强度，从而增强两个电路板11、12在避空区域C12处的连接强度。
请参照图3，为了便于描述，本申请将用521a表示固定于电路板511的第一 固定端，用523a表示固定于电路板512的第二固定端，用避空区域C512分别表示电路板512的避空区域，用A512表示固定于电路板512的第一端。第一固定端521a和第二固定端523a还可以分别位于避空区域C512的相对两侧，也就是说，所述第一固定端521a在第一端A512的正投影区域位于避空区域C512之外，且位于避空区域C512远离所述第二固定端523a的一侧。
请参照图4，第一固定端521a在第一端A512的正投影区域还可以与避空区域C512部分重叠。
可以理解的，请参照图2，异形筋2包括依次连接的第一连接段21、第二连接段22和平行于所述第一连接段21的第三连接段23，所述第二连接段22连接于所述第三连接段23和所述第一连接段21之间，所述第一连接段21的端部为所述第一固定端21a，所述第二连接段22的端部为所述第二固定端23a。优选的，所述第一连接段21、第二连接段22和所述第三连接段23皆为直线段，便于异形筋2的切割加工。具体的，所述第二连接段22分别垂直连接于所述第一连接段21和所述第三连接段23。将异形筋2设置成基本呈“ㄣ”型的结构，第二连接段22在第一端A12上的正投影可以与避空区域C12部分或完全重叠。
当然，在其它实施例中，请参照图5，异形筋52可以为一条直线段，以便于加工制造及减少异形筋52局部受力不均匀造成形变。在图5中显示为与第一端A512相交的倾斜线段，所述第一固定端521a在第一端A512的正投影区域位于避空区域C512中。
请参照图6，所述第一固定端521a在第一端A512的正投影区域与避空区域C512部分重叠。
请参照图7，所述第一固定端521a在第一端A512的正投影区域位于避空区域C512之外，且位于避空区域C512远离所述第二固定端523a的一侧。
请参照图8，异形筋52还可以为S形状。具体可以为曲线形状，以适应电路板上的结构件布局。
为了进一步的改进，请参照图1和图2，所述电路板拼板100还包括第一连接筋3，所述第一连接筋3可以为矩形或圆环形或椭圆形等形状，所述第一连接筋3分别连接于相邻的两个所述电路板10之间，所述第一连接筋3的数量为多个。
在本实施例中，第一连接筋3为规则形状。可以理解的，其可以为矩形、 圆环形或者椭圆形，本实施例中以矩形举例。第一连接筋3适用于拼接的两个电路板分别与第一连接筋3连接的位置为非避空区域C的情况。即在相邻的两个电路板的任意位置上皆可以设置筋条以实现拼接的情况中。此处为了便于描述，将与第一电路板11在第一短边S1方向拼接的另一个电路板定义为第三电路板13，第一电路板11的第三短边S3拼接于第三电路板13的第二短边S2时，可以直接在第一电路板11和第三电路板13之间直接设置多个第一连接筋3实现拼接，而第一电路板11与第二电路板12之间除了异形筋2拼接的位置外，还可以在第一电路板11和第二电路板12的非避空区域C继续设置第一连接筋3，进一步强化第一电路板11与第二电路板12之间的连接强度。通过异形筋2和第一连接筋3对应电路板不同的结构进行组合拼接，在强化了各个电路板之间的连接强度的同时，亦由于第一连接筋3的引入，进一步提高了电路板拼板的加工便捷性。当然，在其它实施例中，异形筋2还可以直接代替第一连接筋3，即相邻的两个电路板之间的拼接皆通过异形筋2实现。
为了更进一步的改进，请参照图9，所述电路板拼板100还包括框架4和第二连接筋5，所述板体1置于所述框架4的内部，所述第二连接筋5连接于所述板体1的侧边与所述框架4之间，所述第二连接筋5的数量为多个。
通过第二连接筋5将板体1固定于框架4上，进一步加强了电路板拼板100的整体式结构。
在本实施例中，框架4优选为包括四条工艺边41的结构，所述四条工艺边41围接形成封闭框体。具体的，框架4为矩形框体，板体1的两条第一短边S0、S1和两条第一长边L0、L1分别与对应的框架4的工艺边41通过第二连接筋5连接。矩形封闭的框架4为多个电路板提供更强的支撑强度，从而使得电路板拼板100在贴片时更不易弯曲。可以理解的，由于工艺边41与板体1的侧边上并无设置避空区域C，为了便于电路板拼板100的加工，第二连接筋5的结构与第一连接筋3的结构相同。其中第二连接筋5的结构请具体参照第一连接筋3的描述，此处不再赘述。当然，在其它实施例中，第二连接筋5的材质可以与第一连接筋3、异形筋2的材质相同。
请参照图10，框架54还可以为包括两条相对设置的工艺边541，两条工艺边541分别靠近两条第一长边L0、L1设置，即板体51通过在两条第一长边L0、L1与两条工艺边541之间设置第二连接筋55，实现板体51固定于框架54上，来 提高电路板拼板200的整体强度。
本发明提供的电路板拼板100通过设置异形筋2连接两个相邻的电路板，其中异形筋2的第一固定端21a与第二固定端23a分别错位设置在一个电路板和另一个电路板上，并且第二固定端23a跨过避空区域C设置在避空区域C的附近，从而能够提高电路板在避空区域C的连接强度，从而提供一种连接强度较佳的电路板拼板100。
可以理解的，电路板拼板100中经过分板之后，单块的电路板能够应用于移动终端。
请参照图11，本申请实施例还提供一种电路板12，所述电路板12包括相背设置的第一端A12和第二端B12，所述第一端A12设有避空区域C12，用于收容结构件D，所述避空区域C12一侧还设有异形筋残留物24，所述异形筋残留物24起始于所述第一端A12，朝向远离所述电路板12方向延伸，且所述异形筋残留24在所述第一端A12上的正投影区域与所述避空区域C12部分重叠。
在其他实施例中，所述第二端B12设有与所述避空区域C12相对的连接区120，所述连接区120内或附近设有所述异形筋残留物25。
请参照图12，本申请实施例还提供一种移动终端300，包括上述电路板12，还包括结构件D，所述结构件D收容于所述避空区域C12内，所述结构件D为电子元器件或移动终端300的壳体部分。
所述移动终端可以是任何具备通信和存储功能的设备，例如：平板电脑、手机、电子阅读器、遥控器、个人计算机(Personal Computer，PC)、笔记本电脑、车载设备、网络电视、可穿戴设备等具有网络功能的智能设备。
以上是本发明的优选实施方式，应当指出，对于本技术领域的普通技术人员来说，在不脱离本发明原理的前提下，还可以做出若干改进和润饰，这些改进和润饰也视为本发明的保护范围。
