可选的，导电弹片50可以是含银、或镁、或铝、或铜等金属件。
可以理解的是，侧键电路板60上连接按键开关63的导电线路从固定基座51的U形臂两个自由端之间走线，以便于连接按键开关63的导电线路与固定基座51避开，使得导电弹片50接收第二心电电极30的电信号，与按键开关63的电信号相互独立传导，保证心电图数据获取的准确性，以及保证侧键70操控的准确性。
在第二心电电极30获取用户心电图数据的过程中，第一心电电极20接触用户手腕的皮肤，用户手指触摸设置了第二心电电极30的侧键70，可以按压侧键70也，可以不用按压侧键70，第二心电电极30经导电弹片50、第二分支42、心电电路板40、第一分支41、第一心电电极20和用户身体整个形成闭合的导通路径，并结合第一心电电极20和第二心电电极30分别接触于用户身体两个非等电位的部位，以使得第二心电电极30和第一心电电极20之间形成电位差，从而实现电子设备100利用心电电路板40上的器件获取用户心电图数据。
在侧键70触发按键开关63的过程中，用户手指按压侧键70，侧键70带动弹性卡舌53及弹性臂52形变，并使得弹性卡舌53抵触按键开关63，进而按键开关发出信号，最终实现触发按键开关63。
在一个实施例中，请一并参阅图10和图11，导电弹片50还设有由固定基座51延伸出的分支基座54和由分支基座54折弯延伸出的分支弹性臂55，分支基座54贴合侧键电路板60，分支弹性臂55与第二分支42弹性抵触。分支基座54由固定基座51的U形环的闭合端延伸出，以增加固定基座51与分支基座54的稳固性。分支基座54位于侧键电路板60靠近背盖11处，以使得分支基座54与第二分支42靠近，进而减小第一心电电极20至导电弹片50的路径。分支基座54与固定基座51之间连接有延伸臂56，延伸臂56贴合侧 键电路板60，使得导电弹片50整体与侧键电路板60稳固。分支弹性臂55由分支基座54远离延伸臂56的一边缘延伸出，使得分支弹性臂55相对侧键电路板60倾斜，以便于分支弹性臂55与第二分支42弹性抵触。
在将第二分支42与侧键电路板60装配的过程中，第二分支42可先接触分支弹性臂55并最终弹性抵触分支弹性臂55的端部，以避免分支弹性臂55的端部刺破第二分支42。利用分支基座54从固定基座51延伸出，分支弹性臂55从分支基座54延伸出，使得分支弹性臂55、分支基座54、固定基座51和弹性臂52一体设置，以便于导电弹片50整体有效导通第二分支42和第二心电电极30，增加电子设备100获取用户心电图数据的灵敏度。
为了增大分支弹性臂55抵触第二分支42的弹性抵触作用力，并且防止分支弹性臂55刺破第二分支42，将分支弹性臂55进行弯折。分支弹性臂55弯折后，分支弹性臂55的端部向分支基座54内折，使得分支弹性臂55的弹性应力增大。分支弹性臂55设置抵触第二分支42的弯曲抵触部552，弯曲抵触部552接触第二分支42的表面呈圆弧曲面，以减小对第二分支42的应力集中，防止第二分支42被刺破。
为了方便分支弹性臂55有效与第二分支42弹性抵触，并且保证分支弹性臂55的有效回弹性，分支基座54设有两个相对的限位卡扣541，两个限位卡扣541对分支弹性臂55的端部有效限位。具体的，两个限位卡扣541由分支基座54在分支弹性臂55两侧边缘延伸出并弯折卷曲而形成，限位卡扣541相对分支基座54折弯，限位卡扣541的端部与分支基座54之间形成限位导滑槽。
可以理解地，分支弹性臂55被按压时容易发生弹性形变，然而，由于分支弹性臂55的厚度一般较小，分支弹性臂55也容易在力的作用下发生塑性变形而无法产生恢复原状的回弹力。利用分支弹性臂55的端部设有限位凸起551，限位凸起551伸入限位卡扣541与分支基座54之间的限位导滑槽内，并且使得限位凸起551可以勾住限位卡扣541，使得限位凸起551得到有效限位。当弯曲抵触部552被拉扯而产生较大幅度形变时，弯曲抵触部552带动限位凸起551移动，限位凸起551可以勾住限位卡扣541，而避免弯曲抵触部552被进一步拉扯变形而导致分支弹性臂55产生塑性变形。例如，弯曲抵触部142被拉扯而使限位凸起551与分支基座54的距离增大，当距离增大到一定程度时，限位凸起551抵持在限位卡扣541上以避免距离继续增大，实现防止弯曲抵触部142进一步被拉扯。
在一个实施例中，请一并参阅图11、图12、图13和图14，第二心电电极30设置于侧键70的键帽，侧键70还设有固定连接第二心电电极30的键柱71，键柱71与第二心电电极30导通，键柱71与弹性臂52的端部弹性抵触，并在第二心电电极30受按压作用下触发按键开关63。
可以理解的是，第二心电电极30可以为金属板件，以便于侧键70的键帽全部作为第二心电电极30。第二心电电极30也可以是形成于侧键70的键帽表面上的金属层，或者是金属片，即侧键70的键帽表面部分或部分区域作为第二心电电极30。当侧键70的键帽整体全部为第二心电电极30时，侧键70还设有套设于第二心电电极30周侧的绝缘套72。绝缘套72采用绝缘材料制成，以使得绝缘套72对第二心电电极30绝缘，绝缘套72将第二心电电极30与中框12隔绝，避免中框12干扰第二心电电极30接收电信号。键柱71为可以导电的金属件。键柱71可以经导电胶粘接于第二心电电极30。导电胶可以将第二心电电极30与键柱71导通。键柱71远离第二心电电极30的一端弹性抵触弹性卡舌53，以实现导电弹片50经键柱71与第二心电电极30导通。导电胶具有一定弹性形变性能，可以使得侧键70在翘起的情况下，导电胶产生形变，而键柱71仍然不会倾斜，保证键柱71可以有效触发按键开关63。为了保证电子设备100的防水性能，键柱71的周侧套设有密封圈，密封圈密封抵触于中框12的按键孔内壁，以使得中框12的按键孔被密封，保证电子 设备100的安全防水性能。
进一步地，请参阅图15和图16，为了保证侧键电路板60和第二分支42的稳固性，电子设备100还包括固定于中框12内侧并与第二侧边122的内壁存在一定间距的电路板支架80，电路板支架80对侧键电路板60有效支撑。具体的，电路板支架80设有与第二侧边122内壁间隔设置的板件。侧键电路板60的一部分贴合于电路板支架80的板件朝向第二侧边122一侧。侧键电路板60的第二部分62相对第一部分61折弯后贴合于电路板支架80的板件背离第二侧边122一侧。为了便于导电弹片50与侧键70接触，以及便于按键开关63可被侧键70触发，导电弹片50和按键开关63均设置于第一部分61背离侧键电路板60的板件一面，以使得导电弹片50和按键开关63可靠近中框12内壁，并方便与侧键70接触。为了便于第二分支42与导电弹片50有效接触，导电弹片50的分支基座54位于第一部分61远离靠近背盖11的边缘。第二分支42远离心电电路板40的端部层叠于第一部分61朝向中框12的一面。利用第二分支42的端部位于侧键电路板60与中框12之间的间距内，使得电子设备100内部空间充分利用有效优化了结构排布。第二分支42连接心电电路板40的部分相对第二分支42层叠于侧键电路板60的部分折弯，并且第二分支42连接心电电路板40的部分由心电电路板40靠近侧键电路板60的边缘延伸出，以减小第二分支42的长度，并有效缩减第一心电电极20与第二心电电极30之间的导通路径。
进一步地，请参阅图17，为了实现电子设备100可以获取到用户心电图数据，电子设备100包括主板和设置于主板的心电芯片，主板可以经柔性电路板及板对板连接器电连接心电电路板，以使得心电芯片经主板及心电电路板电连接第一心电电极20，以及经第二分支42和导电弹片50电连接第二心电电极30，以根据第一心电电极20和第二心电电极30的电信号生产心电图数据。可以理解的是，当用户身体的两个非等电位部位接触第一心电电极20和第二心电电极30时，例如用户身体的左手腕皮肤接触第一心电电极20，右手手指接触第二心电电极30，第一心电电极20和第二心电电极30产生电压差信号，心电芯片获得该电压差信号，并将电压差信号处理成心电图数据。
进一步地，为了便于用户可以看到自己的心电图，电子设备100还包括固定于中框12与背盖11相对显示屏110，显示屏110电连接主板，并经主板接收心电芯片的心电图数据，并根据心电图数据生产可显示的心电图像。用户通过在显示屏110上观察心电图像即可看到自己的心电图。当然，在其他实施方式中，电子设备100可以通过蓝牙、WiFi、5G、4G等通讯网络将心电图像传导至其他具有显示功能的电子设备100，以利用外部具有显示功能的电子设备100显示该心电图像。
在另一个实施例中，请参阅图18，与图16所示实施例大致相同，不同的是导电弹片50固定连接第二分支42。具体的，第二分支42远离心电电路板40的端部贴合于电路板支架80朝向中框12的一面。导电弹片50可以经导电胶粘接于第二分支42的端部背离电路板支架80的一面。导电弹片50可以经导电胶与第二分支42内的导电线缆导通。导电弹片50的固定基座51贴合于第二分支42的端部，弹性臂52相对第二分支42延伸出，并弹性抵触于侧键70的键柱71或者弹性抵触第二心电电极30，以使得导电弹片50将第二分支42与第二心电电极30导通。更为具体的，为了加强第二分支42的端部结构强度，第二分支42背离导电弹片50的一面设有补强层，以使得第二分支42可以有效对导电弹片50支撑，以防止第二分支42受导电弹片50的弹性抵触力挤压变形，保证第二分支42的安全性。当然，在其他实施方式中，导电弹片50也可以是焊接于第二分支42上。
在另一个实施例中，请参阅图19，与图16所示实施例大致相同，不同的是，第二心电电极30与侧键70分离，第二心电电极30为嵌入中框12的金属件，侧键70在中框12上与第二心电电极30并排设置。具体的，电子设备100在第二侧边122设置两个可按压的 侧键70，并在侧键电路板60对应两个侧键70设置两个按键开关63。第二心电电极30设置于两个侧键70之间，第二心电电极30与第二侧边122固定连接。第二心电电极30不可按压，第二心电电极30穿过中框12，以便于导电弹片50的弹性臂52可弹性抵触第二心电电极30，即导电弹片50固定于侧键70电路位于两个按键开关63之间。第二分支42层叠于侧键电路板60上靠近第二心电电极30处，以便于导电弹片50还可与第二分支42弹性抵触。利用导电弹片50与两个按键开关63分离，从而保证按键开关63的电信号不会干扰第二心电电极30与第一心电电极20导通。
在另一个实施例中，请参阅图20，与图10所示实施例大致相同，不同的是，导电弹片50为分体式结构。导电弹片50还设有固定于侧键电路板60并与固定基座51间隔设置的分支导电弹片500，分支导电弹片500经侧键电路板60与固定基座51导通，分支导电弹片500弹性抵触第二分支42。具体的，分支导电弹片500的结构与图示实施例中，导电弹片50的分支基座54及分支弹性臂55的结构类似，不同的是，分支导电弹片500与固定基座51之间是断开的。固定基座51经导电胶粘接于侧键电路板60上，并与侧键电路板60的线路导通。分支导电弹片500经导电胶粘接于侧键70电路上，并与侧键电路板60的线路导通，进而实现分支导电弹片500与固定基座51导通，从而在第二分支42与分支导电弹片500弹性抵触时，第二分支42与第二心电电极30导通。利用导电弹片50采用分体式结构，使得导电弹片50体积有效减小，有利于优化电子设备100内部结构器件排布。当然，在其他实施方式中，分支导电弹片500也可以是焊接于侧键电路板60上，固定基座51也可以是焊接于侧键电路板60上。
