Description

一种电连接器 技术领域
本发明涉及一种电连接器， 特别是涉及一种用在灯具镇流器上的电连接器。 背景技术
电连接器（接线端子）常用来作为电路连通的节点被应用在不同的电器设备中， 常 见的电连 器一般都具有一个插接口， 在使用时， 可以将导线直接伸入插接口中而实现 线路的导通。
根据实际应用场合的不同， 不同的电连接器（接线端子）的结构和接线方式也各不 相同。 如本人在先申请的专利号为 ZL200820088329.8的中国实用新型专利 《一种快速 接线的接线端子》公开了这样一种接线端子， 其包括有绝缘壳体以及设置在该绝缘壳体 中的、 用于连接导线裸端头的至少一个导电接口， 其特征在于导电接口包括有焊片和弹 片，焊片具有矩形封闭框和固定于该封闭框下部的悍脚，弹片呈 U型并具有固定端和自 由端， 弹片的固定端具有凹槽， 凹槽与封闭框的框边相卡配而将整个弹片固定在封闭框 之中， 弹片的自由端具有向下弯折的压线脚。 该实用新型用具有固定端和自由端的弹片 结构， 将弹片卡设在具有封闭框的焊片之中， 该弹片的自由端还可以具有向下弯折的压 线脚， 这样当导线裸端头通过自由端和封闭框框边之间的间隙插入到导电接口中时， 在 弹片的弹力作用下， 导线裸端头就会被卡制在压线脚之下。 ， 但是， 上述专利中的焊片主体开有矩形孔， 焊脚连接在该悍片本体的下部， 弹片则 是卡设在该焊片主体的矩形孔内而实现和焊片的相对固定， 因为焊片本体开设有矩形 孔， 焊片的载流面积较小， 接线端子的导电性能相对较差， 而且， 上述专利中的弹片因 为要卡设固定在焊片的矩形孔内， 要保证矩形孔宽度和弹片宽度尺寸的相匹配， 不仅增 加了加工的难度， 也不利于安装。 发明内容
本发明所要解决的技术问题是针对上述现有技术现状而提供一种焊片的载流面积 大且导电性能好的电连接器。
本发明解决上述技术问题所采用的技术方案为： 该电连接器， 包括有
至少两个相互拼接于一起的绝缘基座，每一所述基座上开设有可供导线插入的接线 孔；
确 认 本 悍片， 固定设置在所述基座内， 用于实现所述导线和电路板的电连接； 弹片， 连接在所述焊片上， 该弹片包括有一自由端以及一固定端， 其中， 所述自由 端具有始终与所述悍片相抵的趋势， 所述固定端固定连接在所述的悍片上； 以及
按钮， 连接在所述基座的上部， 该按钮的底端与所述弹片的自由端相抵； 其特征在于：所述悍片包括有一载流主板，该载流主板的下部.向外突伸有一可与所 述弹片的固定端底部相抵的支撑片， 该载流主板的上边沿向外翻折形成一可与所述弹片 的自由端顶部相抵的挡边， 所述悍片的载流主板、支撑片和挡边形成一 c型横截面， 所 述悍片的底部还一体成型有两分别位于所述支撑片的两侧且前后错开而设的焊脚。
为了提高弹片的夹紧力， 所述弹片横截面呈 V型， 包括端部为所述自由端的第一 侧边、 端部为所述固定端的第二侧边以及连接所述第一侧边和第二侧边的圆弧部， 所述 基座的内壁形成有一垂直向外且与所述圆弧部大小相适配的定位柱。 由于弹片的第一侧 边和第二侧边形成 V型结构， 相比较 U型结构的弹片， 该 V型弹片的自由端和固定端 之间的距离更大， 从而使得弹片的夹紧力更大， 使用更可靠。
为了实现弹片和焊片的快速便捷的连接，所述弹片的第二侧边边沿开设有一方形卡 槽， 所述悍片的载流主板在靠近所述支撑片的一侧开设有一缺口， 该缺口和所述载流主 板的侧边形成一可与所述方形卡槽的开口大小相适配的腰型部，所述卡槽卡设在该载流 主板的腰型部上而实现所述弹片的固定端和所述焊片的连接。 安装时， 只要将弹片的第 二侧边的卡槽对准悍片载流主板的腰型部， 就可以将弹片卡接在焊片上， 结构简单， 连 接和拆卸都十分方便。
为了能够实现相邻基座之间电路的快速导通，所述基座在靠近底部的位置还开设有 一可供导通桥接件插入的通孔，所述焊片的载流主板在对应通孔的位置还成型有一和该 载流主板相垂直的侧板， 该侧板上开设有一可供所述导通桥接件的插脚穿过且和所述通 孔相对齐的孔。只要将导通桥接件的两个插脚分明别插入同一基座内相互对齐的通孔和 焊片侧板的孔， 则可以使得相邻基座之间的悍脚串联导通， 而且导通桥接件可以单独设 计生产， 提高了加工效率， 也便于损坏时单独替换， 如果不需要该串联电路结构， 只需 要将导通桥接件拔出即可， 使用十分方便。
为了便于导线的插入和固定， 所述弹片的自由端沿该弹片的第一侧边边沿向外翻 翘， 所述焊片的挡边在底部形成有一和所述自由端相抵的三角突尖， 并且， 所述三角突 尖具有一和所述基座的接线孔相对而设的导向斜面，在所述自由端和三角突尖相抵的状 态下，所述自由端和三角突尖形成一便于导线插入 V型导向口。当导线从基座的接线口 伸入后， 钦下按钮， 由自由端和三角突尖形成的 V型导向口张开， 导线可以很容易地从 V型导向开口伸入到基座的内部。
与现有技术相比， 本发明的优点在于： 对现有的焊片结构进行了改进， 将原先开有 孔的悍片主体设计成不开孔的载流主板， 并通过上下设置的挡片和支撑片来保证弹片的 限位， 该焊片由于采用了整体式平面结构的载流主板， 相比较现有的悍片结构载流面积 更大， 提高了焊片的导电性能； 而且， 成型于焊片上的悍脚前后错开设置， 增大了爬电 距离， 使得电连接器的耐电压值提高， 进而提高了产品的电气强度， 使得电连接器的整 体性能更佳。 附图说明

为了提高弹片 3的夹紧力， 弹片 3的横截面呈 V型， 弹片包括连接有自由端 311 的第一侧边 31以及连接有固定端 321的第二侧边 32， 为了便于将弹片 3在基座 1内的 安装，在连接第一侧边 31和第二侧边 32的过渡区为一圆弧部 33，基座 1的内壁形成有 一垂直向外且与圆弧部 33大小相适配的定位柱 12，该 V型结构的弹片 3使得自由端 311 和固定端 321的距离增大， 弹片充分张开， 使得弹片的夹紧力更大， 使用更可靠。 本实例的焊片 2结构为本发明的主要发明点， 该焊片 2包括有一载流主板 21， 该 载流主板 21上没有开设可供弹片插入的孔， 载流主板 21为一整体式面板， 使得载流面 积增大， 提高了电连接器的导电性能；
其中， 该载流主板 21的下部向外突伸有一可与弹片 3的固定端 321底部相抵的支 撑片 22, 载流主板 21的上边沿向外翻折形成一可与弹片 3的自由端 311顶部相抵的挡 边 23， 于是， 焊片 2的载流主板 21、 支撑板 22和挡边 23形成 C型横截面； 为了达到 更好的接触效果， 弹片 3的自由端 311沿该弹片 3的第一侧边 31边沿向外翻翘，焊片 2 的挡边 23在底部形成有一和自由端 311相抵的三角突尖 231，该三角突尖 231具有一和 基座 1的接线孔相对而设的导向斜面 232，在自由端 311和三角突尖 231相抵的状态下， 自由端 311和三角突尖 231形成一便于导线插入 V型导向口 5， 当导线从基座 1的接线 口伸入后， 钦下按钮 4， 由自由端 311和三角突尖 231形成的 V型导向口 5张开， 导线 可以很容易地从 V型导向口 5伸入到基座 1的内部；
为了实现弹片 3和焊片 2的固定连接， 弹片 3的第二侧边 32边沿开设有一方形卡 槽 322， 焊片 2的载流主板 21在靠近支撑片 22的一侧开设有一缺口 21'1， 该缺口 211 和载流主板 21的右侧边形成一可与方形卡槽 322的开口大小相适配的腰型部 212，卡槽 322卡设在该载流主板 21的腰型部 212上继而实现弹片 3的固定端 321和焊片 2的连接， 安装时，只要将弹片 3的第二侧边 32的卡槽 322对准焊片 2载流主板 21的腰型部 212， 就可以将弹片 3卡接在悍片 2上， 使得弹片 3和焊片 2的连接结构更加简单， 安装和拆 卸也更为方便；
另外， 焊片 2的底部还一体成型有两个分别位于支撑片 22的两侧且前后错开而设 的焊脚 24， 焊脚 24前后错开能够有效增大爬电距离， 提高该电连接器的耐电压值， 提 升了电连接器的整体性能。
本实施例中， 在基座 1的开口端面上还连接有一用于端面封闭的端盖 7， 为了便于 端盖 7和基座 1的连接安装，在基座 1的开口端面的侧壁上设置有四个拼接凸点 14，其 中三个凸点设置在基座 1的端面侧壁上， 另一个凸点设置在所述定位柱 12的端部， 相 应地， 在端盖 7上开设有可供对应的拼脚插入的四个小孔 71。 实施例二， 参考图 5〜图 8所示：
本实施例二和实施例一的基本结构相同，两者的不同之处在于基座 1在靠近底部的 外侧壁上还开设有一可供导通桥接件 6插入的通孔 13，其中，导通桥接件 6—般为具有 两个插脚 61的电导体， 可以实现相邻基座之间电路的快速导通， 焊片 2的载流主板 21 在对应通孔 13的位置还成型有一和该载流主板 21相垂直的侧板 25， 该侧板 25上开设 有一可供所述导通桥接件 6的插脚 61穿过且和通孔 13相对齐的孔 251。
若需要实现两个基座之间电路的快速导通， 只要将导通桥接件 6的两个插脚 61分 明别插入同一基座内 1相互对齐的通孔 13和焊片 2侧板 25上的孔 251内，则相邻基座 1之间的焊脚 24就经该导通桥接件连通，实现了相邻基座 1之间电路的快速导通；若要 切断该导通电路， 则只要将导通桥接件拔出基座的通孔即可， 此时， 电连接器的功能和 实施一完全相同，使用十分方便。而且，导通桥接件由于和基座内部结构没有装配关系， 可以单独设计生产， 不仅提高了加工效率， 也方便在损坏时单独替换。
