所述弹性元件301具体为弹簧T1，所述弹簧T1位于所述壳体20及PCB板40之间，所述弹簧T1固定于PCB板40上并与所述壳体20电连接。
如图1所示，所述壳体装置100还包括安装于PCB板40上的功能元件101，所述壳体20包括电性连接区21，所述弹簧T1固定于PCB板40上后与所述安装于PCB板40上的功能元件10电连接，并与所述壳体20的电性连接区21电连接。
在本实施例中，所述功能元件101为天线模组10，所述弹簧T1固定于PCB板40上后与所述安装于PCB板40上的天线模组10电连接，并与所述壳体20的电性连接区21电连接，从而建立天线模组10与壳体20的电性连接区21的电连接，而将所述壳体20的电性连接区21作为天线模组10的辐射体。其中，所述壳体20的电性连接区21可为整个壳体20也可为壳体20的部分区域。所述电性连接区21为壳体20的部分区域时，可位于壳体20的中间位置，两侧位置，形状可为方形、圆形、三角形等。
其中，当所述弹簧T1固定于PCB板40上后与所述安装于PCB板40上的天线模组10电连接时，所述壳体装置100为天线装置。以下以功能元件101为天线模组10为例进行说明。
其中，所述PCB板40可以为一仅仅用于安装及承载天线模组10的天线电路板。所述PCB板40也可为一终端设备的主板，除了安装有所述天线模组10外，还安装有其他的功能元件，例如处理器、存储器等。在一些实施例中，所述PCB板40还可以为所述天线模组10的一部分。在另一些实施例中，所述功能元件101可为其他元件，例如，为安装于PCB板40上的电源电路，所述弹簧T1固定于PCB板40上后与安装于PCB板40上的的电源电路的地以及壳体20的电性连接区21连接，而将壳体20的电性连接区21作为公共地。或者，所述功能元件101可为安装于PCB板40上的存储器、处理器、显示芯片等，所述弹簧T1固定于PCB板40上后与安装于PCB板40上的存储器、处理器、显示芯片等以及壳体20的电性连接区21连接，将壳体20的电性连接区21作为静电释放地。
具体的，所述弹簧T1包括第一端31及第二端32，所述第一端31与PCB板40固定连接且与天线模组10电连接，所述第二端32与壳体20的内表面抵触连接，特别的，所述第二端32与壳体20的电性连接区21的内表面抵触连接。其中，所述PCB板40与壳体20的内表面大致平行，所述弹簧T1的伸缩方向大致为沿着第一端31与第二端32的排列方向，即垂直于所述PCB板40或壳体20内表面的方向。
从而，当壳体20受到外力作用而相对于PCB板40产生力的作用，由于弹簧T1可伸缩运动，也可以朝与伸缩方向不同的其他方向扭曲，使得壳体20相对PCB板40发生相对移动时，弹簧T1与壳体20可跟随壳体20一起运动，而保持弹簧T1的第二端32与壳体20的接触位置不变，即连接位置不变。因此，避免了连接结构30与壳体20之间发生摩擦，不会导致壳体20表面磨损引起的接触不良。
其中，所述弹簧T1为螺旋弹簧，且弹簧T1的材质为金属材料。在一些实施例中，所述弹簧T1的表面还镀有金、镍等材料。
所述壳体20为金属壳体，例如为铝合金材质的壳体，所述壳体20为后壳(电池盖)，所述弹簧T1的第二端32为与壳体20的内表面抵触。
在本实施例中，所述弹簧T1的第一端31可通过焊接方式固定于PCB板40上，所述弹簧T1的第二端32通过弹性抵触的方式与壳体20抵触。
其中，弹簧T1由多个螺旋延伸的弹性簧圈组成，弹簧T1第二端32的表面与壳体20的内表面平行，以用于接触面积最大化，弹簧T1的第一端31包括水平段以及自水平段向上倾斜延伸的倾斜段，而形成不封闭的簧圈。
请参阅图3，与图1所示的壳体装置100的区别在于，在另一实施例中，所述弹簧T1的第一端31可与PCB板40一体成型，所述弹簧T1的第二端32也可与壳体20一体成型。即，所述PCB板40与壳体20中的至少一个与弹簧T1一体成型。
请一并参阅图4及图5，为第二实施例中的壳体装置200的示意图。与第一实施例的区别在于，本实施例中，所述连接结构30还包括弹簧卡片K1，所述弹簧卡片K1用于将所述弹簧T1固定于所述PCB板40上。所述弹簧卡片K1包括底板D1，所述底板D1包括相对的第一面F1(如图2所示)以及第二 面F2。所述底板D1的第一面F1正对PCB板40且固定于PCB板40上。所述弹簧T1的第一端31固定于所述底板D1的第二面F2上。
进一步的，底板D1的侧边B1延伸有多个弯折部C1，所述弯折部用以与弹簧T1卡合。具体的，所述弹簧卡片K1的侧边B1朝远离PCB板40的方向均延伸有弯折部C1。所述弯折部C1可为倒L形。每一倒L形的弯折部C1与所述第二面F2共同形成一收容槽S1。其中，所述多个弯折部C1之间可以是相互连接的，也可以为如图3所示的间隔设置，即，多个弯折部C1的侧壁相互衔接或者相互间隔。从而，相应的，所述多个收容槽S1可以是相互独立且分隔的，也可以是相互连通的。
所述弹簧T1的第一端31的线圈收容于所述收容槽S1中，而将所述弹簧T1固定于所述弹簧卡片K1上，进而固定于所述PCB板40上。
如图5所示，所述弹簧卡片K1的三个侧边B1朝远离PCB板40的方向均延伸有弯折部C1，另一个侧边B1开口，从而弹簧T1的第一端31可从所述开口的侧边B1滑进且限定于弹簧卡片K1的若干收容槽S1中。所述弹簧T1的第一端31通过弹簧卡片K1固定于PCB板40后，还与所述天线模组10电接触。
其中，所述开口的侧边B1的外缘处还设置有一挡块N1，优选的，挡块N1用弹性材料制成，安装时，弹簧T1的第一端31从开口处的侧边B1滑入，直至挡块N1的内侧抵触弹簧T1的第一端31的外缘。安装时，挡块N1会被压缩，而弹簧T1进去之后，挡块N1弹起，与所述多个收容槽S1配合而将弹簧T1固定于弹簧卡片K1的底板D1上。显然，在一些实施例中，所述挡块N1可不为弹性材料，而利用圆台形弹簧T1第一端31的簧圈的直径方向上的弹性，而沿着开口处的侧边B1滑进。当滑到挡块N1的内侧抵触圆台形弹簧T1的第一端31的外缘时，所述圆台形弹簧T1第一端31的簧圈恢复形状，而抵触所述挡块N1与多个收容槽S1的侧壁，从而挡块N1与所述多个收容槽S1配合而将圆台形弹簧T1固定于弹簧卡片K1的底板D1上。
所述弹簧卡片K1为金属材料制成，例如为铜、铝、铁等金属材料制成。
在其他实施例中，弹簧T1的第一端31还可通过卡扣连接、铆接等方式固定于PCB板40上。本发明实施例中所述弹簧T1的第一端31与所述PCB板 40的连接方式不受限制。
请参阅图6，可选的实施例中，所述壳体装置200的弹簧卡片K1可与PCB板40一体成型，所述弹簧T1的第二端32也可与所述壳体20一体成型。
请一并参阅图7及图8，在一些实施例中，相比如前所述的壳体装置200，本实施例中的壳体装置300的连接结构30还可包括另一弹簧卡片K2，所述弹簧T1的第二端32通过所述另一弹簧卡片与壳体20电接触。
如图7所示，所述另一弹簧卡片K2包括底板D2，所述底板D2包括相对的第三面F3和第四面F4，所述第三面F3与壳体20的内表面电连接，所述弹簧T1的第二端32固定于所述第四面F4上。
同样的，底板D2的侧边B1延伸有多个弯折部C2，所述弯折部C2用以与弹簧T1卡合。具体的，所述另一弹簧卡片K2的侧边B2朝远离壳体20的方向均延伸有弯折部C2。所述弯折部C2可为倒L形。每一倒L形弯折部C2与所述第四面F4共同形成一收容槽S2。其中，所述多个弯折部C2之间可以是相互连接的，也可以为如图7所示的间隔设置，即，多个弯折部C2的侧壁相互衔接或者相互间隔。从而，相应的，所述多个收容槽S2可以是相互独立且分隔的，也可以是相互连通的。
如图8所示，所述弹簧卡片K2的三个侧边B2朝远离壳体20的方向均延伸有弯折部C2，另一个侧边B2开口，从而弹簧T1的第二端32可从所述开口的侧边B2滑进且限定于弹簧卡片K2的若干收容槽S2中。所述弹簧T1的第二端32通过弹簧卡片K2固定于PCB板40后，还与所述壳体20电接触。其中，所述弹簧卡片K2为金属材料，所述弹簧T1通过所述弹簧卡片K2与壳体20电接触。
同样的，所述弹簧卡片K2的开口的侧边B2的外缘处还设置有一挡块N2，优选的，挡块N2用弹性材料制成，安装时，弹簧T1的第二端32从开口处的侧边B2滑入，直至挡块N2的内侧抵触弹簧T1的第二端32的外缘。安装时，挡块N2会被压缩，而弹簧T1进去之后，挡块N12弹起，与所述多个收容槽S2配合而将弹簧T1的第二端32固定于弹簧卡片K2的底板D2上。在一些实施例中，所述挡块N2可不为弹性材料，而利用圆台形弹簧T1第二端32的簧圈的直径方向上的弹性，而沿着开口处的侧边B2滑进。当滑到第二挡块N2 的内侧抵触圆台形弹簧T1的第二端32的外缘时，所述圆台形弹簧T1第二端32的簧圈恢复形状，而抵触所述挡块N2与多个收容槽S2的侧壁，从而挡块N2与所述多个收容槽S2配合而将圆台形弹簧T1固定于弹簧卡片K2的底板D2上。
在一些实施例中，所述弹簧T1可为圆台形，所述弹簧T1的第一端31组成圆台形的圆台底，所述弹簧T1的第二端32组成圆台形弹簧T1的圆台顶，所述弹簧T1的簧圈的直径从第一端31向第二端32逐渐减小。
所述弹簧T1整体也可呈圆柱形，所述第一端31及第二端32分别为圆柱形弹簧T1的两个端面，所述弹簧T1的簧圈的直径从第一端31至第二端32大致相等。
所述弹簧T1也可为中间瘦，两端胖的葫芦形，所述第一端31及第二端32分别为葫芦形弹簧T1的两个端面。即，所述弹簧T1的簧圈直径从第一端31向大致为弹簧T1中部的位置逐渐减小，然后从大致为弹簧T1中部的位置向第二端32逐渐增大，其中，第一端31的簧圈直径与第二端32的簧圈直径可相等或不相等。
所述弹簧T1也可为中间胖，两端瘦的菱形或水壶形，所述第一端31及第二端32分别为菱形弹簧T1的两个瘦的端子。即，所述弹簧T1的簧圈直径从第一端31向大致为弹簧T1中部的位置逐渐增大，然后从大致为弹簧T1中部的位置向第二端32逐渐减小，其中，第一端31的簧圈直径与第二端32的簧圈直径可相等或不相等。
显然，不论弹簧T1的形状如何变化，弹簧T1第二端32的表面与壳体20的内表面平行，以用于接触面积最大化，弹簧T1的第一端31包括水平段以及自水平段向上倾斜延伸的倾斜段，而形成不封闭的簧圈。
