一种数码卡 技术领域
本申请涉及通信传输技术领域，更具体地，涉及一种数码卡。
背景技术
现有的手机硬件设备中的数码卡，如SIM卡、SD卡等，多采用单弹性臂的弹片结构。这种弹片的弹力小，长期使用会导致弹性臂弹力不足，进而使得接触不良，最终导致数据传输或者通信传输收到影响。从而缩短数码卡的使用寿命。
发明内容
本申请的一个目的是解决现有数码卡长期使用，易导致弹性臂弹力不足，进而使得数码卡与便携式设备接触不良以及使数码卡使用寿命缩短的技术问题。
根据本申请的第一方面，提供了一种数码卡。该数码卡包括：
数码卡本体；
PCB板，所述PCB板设于所述数码卡本体内；
弹片，所述弹片包括多条悬臂，所述悬臂的第一端向上弯折形成接触部，多条所述悬臂的所述接触部的末端连接形成触点；所述悬臂的第二端设于所述数码卡本体，所述第二端与所述PCB板连接。
优选地，多条所述悬臂的第二端位于同一平面。
优选地，所述悬臂为3条，位于两侧的悬臂的接触部向中间倾斜，形成楔形。
优选地，所述悬臂为2条，2条所述悬臂的接触部向中间倾斜，形成楔形。
优选地，所述弹片的材质为铜合金。
优选地，所述数码卡本体还包括外壳，所述外壳的材质为塑胶。
优选地，所述弹片为多个，所述触点位于多排。
优选地，多个所述弹片间隔设置，以使触点形成2排。
优选地，多个所述弹片间隔设置，以使触点形成3排。
优选地，所述弹片一体成型。
本申请的一个技术效果是，该数码卡的弹片设有多条悬臂，并且所述悬臂的第一端向上弯折形成接触部，多条所述悬臂的所述接触部的末端连接形成触点，该结构使得弹片的弹力增加，提高了数码卡的使用寿命。
通过以下参照附图对本申请的示例性实施例的详细描述，本申请的其它特征及其优点将会变得清楚。
附图说明
被结合在说明书中并构成说明书的一部分的附图示出了本申请的实施例，并且连同其说明一起用于解释本申请的原理。
图1：本申请提供的数码卡的弹片的俯视图；
图2；本申请提供的数码卡的弹片的侧视图。
其中，1：悬臂；2：接触部。
具体实施方式
现在将参照附图来详细描述本申请的各种示例性实施例。应注意到：除非另外具体说明，否则在这些实施例中阐述的部件和步骤的相对布置、数字表达式和数值不限制本申请的范围。
以下对至少一个示例性实施例的描述实际上仅仅是说明性的，决不作为对本申请及其应用或使用的任何限制。
对于相关领域普通技术人员已知的技术、方法和设备可能不作详细讨论，但在适当情况下，所述技术、方法和设备应当被视为说明书的一部分。
在这里示出和讨论的所有例子中，任何具体值应被解释为仅仅是示例性的，而不是作为限制。因此，示例性实施例的其它例子可以具有不同的值。
应注意到：相似的标号和字母在下面的附图中表示类似项，因此，一 旦某一项在一个附图中被定义，则在随后的附图中不需要对其进行进一步讨论。
本申请提供一种数码卡，数码卡可以是SIM卡或者SD卡。参照图1-2，该数码卡包括：数码卡本体、PCB板和弹片。PCB板设于所述数码卡本体内。本领域技术人员可以理解，不同的数码卡根据其功能，内置不同的PCB板，以进行数据、信号或者电力的传输，本申请对此不做限定。弹片包括多条悬臂1，悬臂1的第一端向上弯折形成接触部2，多条悬臂的接触部2的末端连接形成触点。触点为弧形面以增大接触面积并便于安装，避免触点成尖锐形状而对待安装件造成损伤。悬臂的第二端设于数码卡本体，第二端与PCB板连接。
为了减小数码卡的厚度，多条悬臂1的第二端位于同一平面。
在一种实施方式中，参照图1，悬臂1为3条，位于两侧的悬臂1的接触部向中间倾斜，形成楔形。两侧的悬臂1与中间的悬臂1的末端连接形成触点，利用的不仅是悬臂1的材料本身的弹性性能，而且利用了3条悬臂1形成的楔形结构的弹性性能，使弹片具有很好的回弹力，延长了弹片的使用寿命。
在另一实施方式中，悬臂1为2条，2条悬臂1的接触部2向中间倾斜，形成楔形。同样，利用了楔形结构的弹性性能，使弹片具有很好的回弹力，延长了弹片的使用寿命。
为了提高数据、信号或者电力的传输性能，弹片1采用铜合金。
为了保护PCB板以及弹片，进一步延长数码卡的使用寿命，数码卡本体还包括外壳，考虑到材料的可塑性高以及加工制作简易，外壳的材质为塑胶。当然，也可以采用塑料、硅胶等材料。
进一步地，弹片为多个，多个弹片的触点位于多排。这样，可以使弹片的电信号传输更均匀，避免局部电流过大。
在一种实施方式中，多个弹片间隔设置，以使触点形成2排。在另一种实施方式中，多个弹片间隔设置，以使触点形成3排。都能使电信号均匀传输。
为了便于加工并保证结构的稳固，弹片采用一体成型加工工艺，弹片 可以采用注塑方法一体注塑成型，也可以采用一次冲压成型。当然也可以采用其他加工工艺。
本实用新提供的数码卡的弹片设有多条悬臂1，并且所述悬臂1的第一端向上弯折形成接触部2，多条悬臂1的接触部2的末端连接形成触点，该结构使得弹片的弹力增加，保证弹片与便携式设备形成良好的接触。提高了数码卡的使用寿命。
虽然已经通过例子对本申请的一些特定实施例进行了详细说明，但是本领域的技术人员应该理解，以上例子仅是为了进行说明，而不是为了限制本申请的范围。本领域的技术人员应该理解，可在不脱离本申请的范围和精神的情况下，对以上实施例进行修改。本申请的范围由所附权利要求来限定。
