具体实施方式
以下基于实施例对本申请进行描述，但是本申请并不仅仅限于这些实施例。在下文对本申请的细节描述中，详尽描述了一些特定的细节部分。对本领域技术人员来说没有这些细节部分的描述也可以完全理解本申请。为了避免混淆本申请的实质，公知的方法、过程、流程、元件和电路并没有详细叙述。
此外，本领域普通技术人员应当理解，在此提供的附图都是为了说明的目的，并且附图不一定是按比例绘制的。
除非上下文明确要求，否则在说明书的“包括”、“包含”等类似词语应当解释为包含的含义而不是排他或穷举的含义；也就是说，是“包括但不限于”的含义。
在本申请的描述中，需要理解的是，术语“第一”、“第二”等仅用于描述目的，而不能理解为指示或暗示相对重要性。此外，在本申请的描述中，除非另有说明，“多个”的含义是两个或两个以上。
除非另有明确的规定和限定，术语“安装”、“相连”、“连接”、“固定”等术语应做广义理解，例如，可以是固定连接，也可以是可拆卸连接，或成一体；可以是机械连接，也可以是电连接；可以是直接相连，也可以通过中间媒介间接相连，可以是两 个元件内部的连通或两个元件的相互作用关系，除非另有明确的限定。对于本领域的普通技术人员而言，可以根据具体情况理解上述术语在本申请中的具体含义。
当一元件或层被提及为在另一元件或层“上”、“被接合到”、“被连接到”或“被联接到”另一元件或层时，其可直接在另一元件或层上、被直接接合、连接或联接到另一元件或层，或者可存在中间元件或层。相比之下，当一元件被提及为“直接”在另一元件或层“上”、“直接被接合到”、“直接被连接到”或“直接被联接到”另一元件或层时，可不存在中间元件或层。用于描述元件之间关系的其它词语应该以相似方式被解释(例如，“之间”与“直接在之间”，“邻近”与“直接邻近”等)。如在此使用的，术语“和/或”包括一个或更多关联的所列项目中的任一或全部组合。
为易于说明，诸如“内”、“外”、“之下”、“下方”、“下部”、“上方”、“上部”等等的空间相关术语在此被用于描述图中例示的一个元件或特征与另一元件或特征的关系。将理解的是，空间相关术语可意欲包含设备在使用或操作中的除图中描绘的方位之外的不同的方位。例如，如果图中的设备被翻转，则被描述为在其它元件或特征“下方”或“之下”的元件于是将被定位为在该其它元件或特征“上方”。因而，示例术语“下方”能包含上方和下方的方位二者。设备可以以其它方式被定向(旋转90度或处于其它方位)，并且在此使用的空间相关描述词应该被相应地解释。

所述第一弹片电极和所述凹槽配合，以夹持与所述接线端子配合的导线、连接器或者电路板。
在本申请实施例中，通过在第一弹片电极上设置至少二个第一凸起端，能够提高接线端子连接的稳定性。
图4是本申请第一实施例的应用场景示意图。如图4所示，连接端子与PIN针40电连接。第一弹片电极20和第二弹片电极30夹持PIN针40。第一弹片电极20和第二弹片电极30的最小间距小于PIN针的外径。当PIN针***第一弹片电极20和第二弹片电极30之间时，第一弹片电极20上形成向外的形变，向靠近第一内壁111的方向移动，使得第一接触端22与第一内壁111接触，从而使第一接触端22受到第一内壁111的反作用力；第二弹片电极30上形成向外的形变，向靠近第二内壁112的方向移动，使得第二接触端32与第二内壁112接触，从而使第二接触端32受到第二内壁112的反作用力，由此，使第一弹片电极20和第二弹片电极30具有向内的作用力，进而能够稳定的夹持PIN针。
由于PIN针***第一弹片电极20和第二弹片电极30的过程中首先接触第一凸起端212和第二凸起端312。第一凸起端212和第二凸起端312之间的距离略小于PIN 针的直径。这样，当PIN针处于第一凸起端212和第二凸起端312之间时，受到较小的夹持力，由于在第一凸起端212和第二凸起端312之间时，PIN针需要继续向内***的距离较长，较小的夹持力能够避免在插拔过程中造成PIN针损伤，从而延长PIN针的使用寿命。第一凸起端211和第二凸起端311之间的距离小于第一凸起端212和第二凸起端312。因为PIN针到第一凸起端211和第二凸起端311之间的位置时，PIN针需要继续向内***的距离较短，因此，第一凸起端211和第二凸起端311之间的距离较小，使PIN针受到较大的夹持力，使PIN针和第一凸起端211和第二凸起端311之间的接触稳定。且PIN针位于第一凸起端211和第二凸起端311之间的位置时，会使第一弹片电极和第二弹片电极发生较大形变，从而使第一接触端22受到第一内壁111的反作用力更大，第二接触端32受到第二内壁112的反作用力更大。这样可以使第一凸起端212和第二凸起端312的夹持力增大。
在本申请实施例中，通过在第一弹片电极上设置至少二个第一凸起端，在第二弹片电极上设置至少二个第二凸起端，能够稳定的夹持PIN针，同时避免PIN针插拔过程中被损伤，延长PIN针的使用寿命。
图5是本申请第一实施例的应用场景示意图。如图5所示，多个依次排列的连接端子与印刷电路板50电连接。第一弹片电极20和第二弹片电极30夹持印刷电路板50。第一弹片电极20和第二弹片电极30的最小间距小于印刷电路板50的厚度尺寸。当印刷电路板50***第一弹片电极20和第二弹片电极30之间时，第一弹片电极20上形成向外的形变，向靠近第一内壁111的方向移动，使得第一接触端22与第一内壁111接触，从而使第一接触端22受到第一内壁111的反作用力；第二弹片电极30上形成向外的形变，向靠近第二内壁112的方向移动，使得第二接触端32与第二内壁112接触，从而使第二接触端32受到第二内壁112的反作用力，由此，使第一弹片电极20和第二弹片电极30具有向内的作用力，进而能够稳定的夹持印刷电路板50。
在本申请实施例中，通过在第一弹片电极上设置至少二个第一凸起端，在第二弹片电极上设置至少二个第二凸起端，能够稳定的夹持印刷电路板，同时避免印刷电路板插拔过程中被损伤，延长印刷电路板的使用寿命。
