本申请要求于2016年1月19日提交中国专利局、申请号为2016200517718、发明名称为“弹片”的中国专利申请的优先权，其全部内容通过引用结合在本申请中。
技术领域
本发明涉及电子技术领域，尤其涉及弹片。
背景技术
随着电子技术的不断发展，电子设备成为了人们生活中必不可少的工具。由于电子设备产生的电磁辐射严重的影响了通信质量，人体的安全和健康，所以电子设备的电磁辐射量减小的要求，以及防静电的要求也应运而生，通过电子设备里的金属件增加弹片来接地的方式来达到上述要求。
在现有技术中，弹片多为单触点的接地方式，在一些表面接触效果较差或者因外部震动而使弹片脱离接触点导致电子电路不能导通，接地效果差，影响电子产品功能的稳定性，达不到电磁辐射量减小以及防静电的要求。
