[0050] 请参照图 2、 图 3和图 4, 本发明的实施例一为: 一种双边矩形抗冲击弹片连接 器, 优选为 Mini矩形抗冲击弹片连接器, 包括上侧接触部 1、 第一侧板、 第二侧 板、 第一 S形上升力臂 6、 第二 S形上升力臂 7和与上侧接触部 1平行的方形底板 8 , 上侧接触部 1的中心与方形底板 8的中心位于同一竖直线上, 上侧接触部 1上表 面的中心还有一凸点 13, 方便对其进行摁压, 下表面外缘设有一圈朝向底板凸 边 14, 所述底板 8优选是正方形的, 使得底部 SMT焊接面积更大, 让焊板后产品 附着力明显提升, 根据实际需求底板 8可以设有一个或多个通孔, 以防止虚焊情 况的发生, 本实施例选择的是在底板 8中心设置一个通孔 11。
[0051] 所述 S形上升力臂整体呈 S形, 其两端与底板之间的间距不同, 也就是说, S形 上升力臂以 s形盘旋而上。
[0052] 第一侧板和第二侧板分别与底板 8的一组相对边相连, 且第一侧板和第二侧板 与底板的相连处优选位于底板的两相对角上; 第一 S形上升力臂 6上端与上侧接 触部 1的一侧边通过一弯折部 12相连, 另一端与第一侧板一端相连, 第二 S形上 升力臂 7与第一 S形上升力臂 6关于连接器中心对称设置且其一端悬空设置于上侧 接触部 1下方且具有一延伸部 15, 使其在工作吋能够更好的对上侧接触部 1进行 支撑, 另一端与第二侧板一端相连。 两个 S形上升力臂的一个与上侧接触部相连 , 另一个则不相连, 可避免两者下压变化不一致导致下压受限。 [0053] 所述第一侧板包括垂直相连的第一侧板的第一部分 2和第一侧板的第二部分 3, 所述第一侧板的第一部分 2为 L形, 其短边一端 (即短边的端部) 与所述底板相 连, 其长边一端 (即长边的端部) 与所述第一侧板的第二部分 3—端相连, 所述 第一侧板的第二部分 3另一端与所述第一 S形上升力臂 6相连。 所述第二侧板包括 垂直相连的第二侧板的第一部分 4和第二侧板的第二部分 5, 所述第二侧板的第 一部分为 L形, 其短边一端 (即短边的端部) 与所述底板相连, 其长边一端 (即 长边的端部) 与所述第二侧板的第二部分 5—端相连, 所述第二侧板的第二部分 5另一端与所述第二 S形上升力臂 7相连。 所述第一侧板的第一部分、 第一侧板的 第二部分、 第二侧板的第一部分、 第二侧板的第二部分分别与底板的四边相对 应。 所述垂直相连的连接处为圆角, 将连接处做成圆角有利于消除弯曲应力, 提高连接处的强度。
[0054] 进一步的, 本实施例的弹片连接器还可包括第三侧板 9和第四侧板 10, 所述第 三侧板 9位于第一侧板的第二部分 3的外侧且与所述底板 8相连, 所述第四侧板 10 位于第二侧板的第二部分 5的外侧且与所述底板 8相连, 四个侧板是四面抗冲击 保护臂, 有非常好的抗冲击能力,当连接器受到外力冲击吋, 四面抗冲击保护臂 牢牢的保护住力臂不受挤压, 从而起到很好的抗冲击作用。
[0055] 如图 5所示为本实施例弹片连接器自由状态示意图, 此吋, 第二 S形上升力臂的 上端悬空, 未接触上侧接触部 1。 当上侧接触部受力下压吋, 如图 6, 上侧接触 部接触第二 S形上升力臂, 两个上升力臂均在压力下下移。
[0056] 实施例二
[0057] 实施例二与实施例一基本构造相同, 是本发明的另一种表现形式, 请参照图 7 , 本发明的实施例二与实施例一的区别在于第一侧板和第二侧板的结构不同, 具体为:
[0058] 所述第一侧板包括垂直相连的第一侧板的第一部分 2和第一侧板的第二部分 3, 所述第一侧板的第一部分 2为 L形, 其短边一端 (即短边的端部) 与所述底板相 连, 其长边一端 (即长边的端部) 与所述第一 S形上升力臂相连, 其短边的外侧 边与第一侧板的第二部分 3相连;
[0059] 所述第二侧板包括垂直相连的第二侧板的第一部分 4和第二侧板的第二部分 5, 所述第二侧板的第一部分 4为 L形, 其短边一端 (即短边的端部) 与所述底板相 连, 其长边一端 (即长边的端部) 与所述第二 S形上升力臂相连, 其短边的外侧 板与第二侧板的第二部分 5相连。
[0060] 如图 7所示, 第一侧板的第二部分和第二侧板的第二部分 3和 5与底板的同一边 对应设置, 可选的, 也可分别底板的相对边对应设置。
[0061] 实施例三
[0062] 本实施例是在实施例二的基础上进行简化, 提供一种单边矩形抗冲击弹片连接 器, 采用单 S形上升力臂, 适用于焊接区域更小的焊板, 请参照图 8, 本发明的 实施例三为:
[0063] 一种矩形抗冲击弹片连接器, 包括上侧接触部 1、 第一侧板、 第一 S形上升力臂 6和底板 8 ; 所述第一侧板包括垂直相连的第一侧板的第一部分 2和第一侧板的第 二部分 3, 所述第一侧板的第一部分 2为 L形, 其短边一端 (即短边的端部) 与所 述底板相连, 其长边一端 (即长边的端部) 与所述第一 S形上升力臂相连, 其短 边的外侧边与第一侧板的第二部分 3相连。 所述第一 S形上升力臂通过一弯折部 1 2与上侧接触部 1相连。 相应的, 本实施例的底板和上侧接触部可为长方形, 其 大小和形状可根据单边 S形上升力臂的大小相应设置。
[0064] 本实施例提供的单边矩形抗冲击弹片连接器, 进一步减小了连接器尺寸, 使用 范围更广, 能满足更多的需求。
[0065] 综上所述, 本发明提供的一种矩形抗冲击弹片连接器尺寸小、 弹力大、 抗冲击 能力强, 采用 S形上升力臂结构在相同单位体积能够获得更大的弹力, 从而使连 接器小型化, 侧板的设置能够为力臂提供足够的保护提高连接器抗冲击能力, 底板设置通孔能够防止虚焊, 焊板后产品附着力明显提升, 圆角的设置有利于 消除弯折应力, 工艺简单、 加工方便。
