参照图2至图5所示，本实施例提供了一种密封型弹片插座端子，包括压接尾部100和本体200，压接尾部100用于固定导线，本体200与压接尾部100 连接，本体200包括抵压板210和第一弹片300，第一弹片300由本体200的端部弯折形成，第一弹片300朝向抵压板210的一侧弯折设置有第一弯折凸起310，当插头端子500的插针510插接于抵压板210和第一弹片300之间时，插针510的侧壁抵靠于第一弯折凸起310。
在本实施例中，第一弹片300由本体200的端部弯折形成，本体200与第一弹片300一体成型，制造过程简单；当插头端子500的插针510插接于抵压板210和第一弹片300之间时，插针510的侧壁抵靠于第一弯折凸起310，通过第一弹片300的弹性恢复力使第一凸起挤压插针510，能有效增加连接的稳定性，且插针510与第一弯折凸起310的接触面积大，有效降低插针510的磨损，插头端子500插拔顺畅。此外，第一弯折凸起310通过弯折形成，只需调整用于成型第一弯折凸起310的部分模具构件的角度位置即可完成第一弯折凸起310成型尺寸的调整，模具调整方便。
具体地，第一弯折凸起310的形状可以但不限于弧形，便于制造成型。进一步地，第一弯折凸起310设置于第一弹片300的端部。进一步地，第一弯折凸起310的两侧均设置有弯折部311，通过弯折部311以实现第一弹片300变形时的应力释放。优选地，弯折部311可以但不限于圆弧过渡。
具体地，压接尾部100与本体200一体成型，方便批量制作生产。进一步地，该密封型弹片插座端子可以但不限于一体冲压成型。进一步地，该密封型弹片插座端子的材质可以为但不限于铜合金，铜合金性能高，利于该密封型弹片插座端子一体冲压成型。
具体地，压接尾部100弯折设置有接线压片110，接线压片110能弯折并压接固定导线，接线方式简单可靠。具体地，压接尾部100的内侧面设置有凹槽120，当接线压片110将导线压紧于压接尾部100时，导线会被压弯并嵌入凹槽120内，使导线的压接更加稳固。
具体地，本体200为一体弯折成型的箱型结构，第一弹片300成型于箱型结构内，抵压板210为箱型结构的侧壁，一体成型的箱型结构便于制造生产，且便于插头端子500与该密封型弹片插座端子的对接。在本实施例中，将第一弹片300成型于箱型结构内，方便存放，能有效防止第一弹片300因磕碰、拉挂或挤压而导致的变形产生，避免影响该密封型弹片插座端子的使用性能。
于本实施例中，继续参照图2所示，本体200上弯折设置有第二弹片400，第二弹片400设置于第一弹片300的下方，当插针510插接于抵压板210和第 一弹片300之间时，第二弹片400抵靠于第一弹片300上。在本实施例中，第二弹片400挤压第一弹片300，进而辅助第一弹片300挤压插针510，使插针510更加稳固的插接于抵压板210和第一弹片300之间。

此外，现有技术中，为使插头端子500美观、提高防腐蚀、增加导电能力或提高焊锡性，通常也会在插头端子500表面增加镀层。因镀层的导电能力、摩擦系数以及软硬程度等的不同，为防止插针510于抵压板210和第一弹片300之间滑动，且在不损坏镀层的情况下，需针对不同镀层的插头端子500的插针510提供不同的挤压力，第二弹片400相对于抵压板210的倾斜角度可调，进而第二弹片400对第一弹片300的挤压力可调，能有效改变第一弯折凸起310对插针510的挤压力，进而使该密封型弹片插座端子适配各种镀层的插头端子500。具体地，该密封型弹片插座端子的镀层材质可以与插头端子500的镀层材质相同，也可以与插头端子镀层的材质不同，在此不再做过多限定。
具体地，第二弹片400朝向抵压板210的一侧弯折设置有第二弯折凸起410，当插针510插接于抵压板210和第一弹片300之间时，第二弯折凸起410抵靠于第一弹片300背向抵压板210的侧面上。具体地，第二弯折凸起410的形状可以但不限于弧形，便于制造成型。在本实施例中，第二弯折凸起410的设计能有效防止第二弹片400的端部与第一弹片300接触而刮花第一弹片300，进而影响插拔顺畅性。
在本实施例中，第一弹片300和第二弹片400均经多次弯折成型，有利于第一弹片300和第二弹片400的应力应变释放。
于本实施例中，继续参照图2所示，本体200上弯折设置有限位部220，限位部220设置于第一弹片300的下方，限位部220能有效防止第一弹片300过度弯折而破坏第一弹片300的疲劳弹性的情况发生，提高该密封型弹片插座端子的使用寿命。具体地，限位部220由箱型结构的侧壁弯折成型，方便制造生产。进一步地，限位部220与第二弹片400均由箱体结构的同一侧壁弯折成型。
于本实施例中，继续参照图2所示，抵压板210朝向第一弹片300的一侧弯折设置有凸起211，当插针510插接于抵压板210和第一弹片300之间时， 插针510的侧壁抵靠于凸起211。在本实施例中，第一弯折凸起310与凸起211之间形成有一定间隙的夹口，通过此夹口与插针510配合实现接触导通。在本实施例中，凸起211通过冲压成型。
示例性地，当插针510朝夹口插入的过程中，插针510挤压第一弯折凸起310，使第一弹片300朝第二弹片400弯折并与第二弹片400的第二弯折凸起410接触，第二弹片400弯折，进而第二弹片400辅助第一弹片300将插针510压紧于凸起211上，连接稳固，且限位部220有效防止第一弹片300过度弯折，提高该密封型弹片插座端子的使用寿命。
显然，本申请的上述实施例仅仅是为了清楚说明本申请所作的举例，而并非是对本申请的实施方式的限定。对于所属领域的普通技术人员来说，能够进行各种明显的变化、重新调整和替代而不会脱离本申请的保护范围。这里无需也无法对所有的实施方式予以穷举。凡在本申请的精神和原则之内所作的任何修改、等同替换和改进等，均应包含在本申请权利要求的保护范围之内。
