2.悬臂从插接臂的自由端向叠片基体延伸的方向为对插端子插入插接端子的方向，实际应用中避免了因从斜向插入而造成的悬臂失效，从而避免影响插接端子与对插端子的电接触。
3.叠片端子堆叠后采用卡扣固定，起到了防止叠片端子转动和固定叠片端子的作用，卡扣可以为塑料或其他硬性材料，节约成本；
4.当对插端子插入插接端子后，插接臂张开，叠片基体受到的张力会通过固定卡扣进行传导，卡扣的设置可以为插接臂提供支撑力，避免对插端子插拔次数过多造成的插接端子失效。
5.通过在固定侧壁的内侧设置弹片，当对插端子插入插接端子时，弹片收缩，导致固定凹槽收缩，起到了对插接端子固定支撑的作用；
6.插接端子与弹片的固定块配合，因弹片的弹性作用，在插接端子安装过程中可拆卸，为后期的维护节约了成本；
7.本插接端子装于绝缘体后，可实现与对插端子90°和180°两个方向的插合，实现与大电流对插端子的转接。

具体实施方式
下面将结合本申请实施例中的附图，对本申请实施例中的技术方案进行清楚、完整地描述，显然，所描述的实施例仅仅是本申请一部分实施例，而不是全部的实施例。基于本申请中的实施例，本领域普通技术人员在没有做出创造性劳动前提下所获得的所有其他实施例，都属于本申请保护的范围。
如图1-图3所示，本申请第一方面的实施例提供一种插接端子100，包括多个沿横向层叠设置的叠片端子10，每一叠片端子10包括：叠片基体11和自叠片基体11的一端纵向延伸且成对设置的插接臂12，比如两个相对设置的插接臂12，成对设置的插接臂12之间形成插接空间13；插接臂12上自其自由端到叠片基体11依次设置有朝向插接空间13凸起的接触部121和凸伸的具备弹性的悬臂122；多个插接空间13沿横向层叠设置形成插接槽23，插接槽23用于与对插端子200(图13)对接，以实现插接端子100和对插端子200的电连接，横向方向为如图3所示的端子叠片10堆叠的方向。
插接端子100的每个叠片端子10的插接臂12上设置悬臂122，增加了插接端子100与对插端子200的接触点，增大了插接端子100与对插端子200的接触面积；
当对插端子200插入插接端子100时，接触部121和悬臂122与对插端子200进行接触并实现电连接，能够保障连接的可靠性和导电效果。多个叠片端子10组合成插接端子100能够保证夹持结构稳固，减少变形，增加插接臂12的强度。
在一实施方式中，如图4-图7所示，每一叠片端子10还包括自叠片基体11的另一端纵向延伸且成对设置的插接臂12，比如另外两个相对设置的插接臂12。通过在叠片基体11的两端分别设置插接臂12，使叠片端子10可以在两个相反的方向上与对插端子200插接。
叠片端子10可以利用板材冲压或切割而成，叠片端子10为薄片状，该插接端子100中的叠片端子10层叠分布，使该插接端子100具有较高的机械连接性能，同时保障了该插接端子100与对插端子200的导电连接性能。板材冲压或切割的加工方式简单，工艺成熟，可以快速大批量的加工叠片端子10，节省加工成本，提高生产效率。与该插接端子100配合的对插端子200可以为片状或者板状。通过调整插接臂12的宽度或者叠片端子10的数量，可以控制夹紧力的大小，方便与对插端子200适配，满足多种对插要求。通过设置不同尺寸的插接臂12，可以适应不同形状的对插端子200。
在一实施方式中，如图4-图5所示，叠片端子10中的接触部121对称设置。因此，在将对插端子200插入插接槽23的时候，对插端子200两侧的应力对应，实现更好的夹持效果。
在一实施方式中，如图4-图5所示，叠片端子10中的悬臂122对称设置。因此，在将对插端子200插入插接槽23的时候，对插端子200两侧的应力对应，实现更好的夹持效果。
在一实施方式中，如图1-图7所示，悬臂122从插接臂12的自由端朝向叠片基体11延伸。悬臂122从插接臂12的自由端朝向叠片基体11延伸的方向为对插端子200插入插接槽23的方向，因此在实际应用中避免了对插端子200因从斜向插入而造成的悬臂122失效，从而避免由此导致的插接端子100与对插端子200的电接触不良。
在一实施方式中，如图5所示，悬臂122的自由端一侧具有弯折部1221，弯折部1221的外侧朝向插接空间13。
悬臂122设置有弯折部1221，这在插接端子100插入对插端子200时能够增加叠片端子10对对插端子200的夹持力。弯折部1221的外侧为突起的一侧。
在一实施方式中，成对设置的插接臂12上的弯折部1221之间的最小距离小于或等于成对设置的插接臂12上的接触部121之间的最小距离。处于自由状态的两个相对的弯 折部1221之间的最小距离小于或等于处于自由状态的两个相对的接触部121之间的最小距离，这在对插端子200插入插接槽23时，能够使悬臂122对对插端子200产生更好的夹持力。
在一实施方式中，如图1-图3所示，每一叠片基体11的一端包括相对设置的至少一对卡扣凹陷14，如图8所示，多个叠片基体11的卡扣凹陷14分别沿横向层叠设置形成对应的卡扣凹槽24；如图3所示，插接端子100还包括至少一对第一卡扣30，如图9所示，第一卡扣30包括固定部301和设置在固定部301两端的卡持部302，一对第一卡扣30的固定部301分别扣合在对应的卡扣凹槽24内，至少一对第一卡扣30的卡持部302相互卡接，以将多个叠片端子10固定在一起。
如图3所示，可以是一对第一卡扣30与带有一对卡扣凹槽24的插接端子相配合，也可以如图6所示，插接端子100包含两对卡扣凹槽24，两对第一卡扣30分别与两对卡扣凹槽24相配合，以将多个叠片端子10固定在一起。
第一卡扣30的材质为塑料材质或其他硬性材料。
在一实施方式中，如图13-图14所示，当对插端子200插入插接端子100后，插接臂12张开，叠片基体11受到的张力会通过第一卡扣30进行传导，第一卡扣30的设置可以为插接臂12提供支撑力，避免对插端子200插拔次数过度造成的插接端子100失效。
在一实施方式中，如图4-图6、图7所示，每一叠片基体11的两端分别设置有相对的卡扣凹陷14，如图8所示，多个叠片基体11的两对卡扣凹陷14分别沿横向层叠设置形成对应的卡扣凹槽24，叠片基体11的一端的卡扣凹陷14与另一端的卡扣凹陷14之间还设置有固定凹陷15，多个叠片基体11的固定凹陷15沿横向层叠设置形成固定凹槽25；如图10所示，插接端子100还包括一对第二卡扣31，第二卡扣31包括固定部301和设置在固定部301两端的卡持部302，固定部301具有中空结构32将固定部301分为第一固定部311和第二固定部312，第一固定部311和第二固定部312分别扣合在对应的卡扣凹槽24内，一对第二卡扣31的同侧的卡持部302相互卡接，将多个叠片端子10固定在一起，固定凹槽25通过中空结构32显露。
第二卡扣31的材质为塑料材质或其他硬性材料。
本申请第二方面的实施例提供一种插接端子安装结构，包括相对设置的固定侧壁40和插接端子100，固定侧壁40的内侧分别设置有延伸出的弹片41，弹片41的端部分别设置有突出的固定块42，固定块42与固定凹槽25配合连接。
固定侧壁40的内侧设有弹片41，当对插端子200插入插接端子100时，弹片41收缩，致固定凹槽25收缩，起到了对插接端子100固定支撑的作用；插接端子100与弹片41的固定块42配合，因弹片41的弹性作用，在插接端子100安装过程中可拆卸，如图11和图12所示的方向设置，将插接端子100从下至上安装至固定侧壁40，因弹片41的弹性作用，插接端子100可以很容易的插入对向设置的两处固定侧壁40之间，进而使固定块42能够成功插入到固定凹槽25内，为后期的维护节约了成本；如图13-图15所示，插接端子100装于绝缘体后，可实现与对插端子200在90°和180°两个方向的插合，插接方向都为自上而下插接，实现与大电流对插端子200的转接。
