Description

一种快速连接免螺丝接线端子 技术领域
本发明具体涉及一种快速连接免螺丝接线端子。
 背景技术
众所周知，接线端子就是用于实现电气连接的一种中间连接器，其主要作用便是为了方便导线的电连接；现有市场上，一般具有两种类型的接线端子，其一为采用螺丝将导线紧固的接线端子，这种结构的接线端子由于其连接导线时需要额外对螺丝进行松紧调节，极大的影响了电工的安装效率，并且其使用场合比较考究，比如震荡的环境当中或者户外场合长时间使用之后，螺丝就比较容易松动，进而导致导线脱落或者接触不良，限制了其使用寿命；其二为无螺丝调节的快速连接接线端子，这种免螺丝结构的接线端子主要存在的缺陷在于：一般只适用于硬质导线的直接插设而形成电连接，如果涉及到软质导线需要介入接线端子时，则往往因为接线端子上不具备可调节接触簧片的结构，极大增加了接线的难度，与此同时，也有部分厂商推出一种在接线端子上开设通孔，然后在需要接软线时，用螺丝刀穿过通孔而强制性使内设于接线端子腔体的弹性簧片变形，再将软性导线通过进线孔插进去，这种结构的接线端子有一个缺陷：便是外力（比如螺丝刀等）会很容易将弹性簧片破坏性变形，进而影响接线效果；基于上述因素，本申请人研发设计了本发明的快速免螺丝接线端子。
 技术问题
本发明的目的在于提供一种结构简单、接线平稳可靠且不易损坏弹性簧片的快速免螺丝接线端子。
 技术解决方案
为实现上述目的，本发明涉及一种快速连接免螺丝接线端子，包括手柄、卡接于一体的上盖和底座以及设置于该接线端子内腔的导电板、弹性簧片，本说明书中，所述上盖和底座的卡接结构具体描述如下：所述上盖上具有向下延伸的卡板，所述卡板上具有楔形卡接部，所述底座的前后两侧壁上、与所述楔形卡接部相对应的位置形成卡接孔，所述上盖与底座通过所述楔形卡接部与卡接孔的卡接连接而形成一体式结构；所述手柄铰接于所述上盖上，所述上盖开设有进线孔和出线孔，所述弹性簧片具有定位板和从所述定位板的边沿呈斜向上延伸的压簧片，所述压簧片上、靠近顶端位置具有冲压成型的接触簧片，所述接触簧片的两侧形成压片，所述手柄具有推板以及从所述推板其中一端的前后两侧边沿位置、呈斜向下延伸的压板，所述压板与所述压片形成抵接，所述接触簧片与所述导电件形成抵接；本说明书中，所述手柄与所述上盖之间的铰接结构具体描述如下：所述压板的外侧面上形成柱形凸缘，所述上盖的上端面上开设有纵向开口，所述纵向开口的前后两侧壁形成纵向适配槽，所述手柄通过所述柱形凸缘与所述纵向适配槽的适配而形成与上盖之间的铰接连接。
本说明书中，为了使弹性簧片能有效的被限位在底座上，在所述底座上、位于定位板横向两侧边沿的位置具有用于限制弹性簧片横向偏移的限位横梁，所述定位板前后两侧边沿、靠中间位置形成内凹的定位槽，所述底座上、与所述定位槽相对应的位置形成与所述定位槽适配的纵向限位板，通过限位横梁和纵向限位板的设置，使得弹性簧片在横向方向上和正向方向上都被有效的限位，进一步保证了接线的可靠性。
同时，当本说明书中接线端子的进线孔和出线孔分别开设在所述上盖的横向两侧时，为了避免引进进线孔和出线孔的导线在接线端子内腔接触，特意设置了在所述导电板的靠中间位置具有冲压成型的纵向隔板。
所述手柄上、靠近所述压板的位置具有从所述推板上纵向向下延伸的纵向限位梁，所述导电板上、靠近所述纵向限位梁的位置具有垂直于所述导电板延伸的纵向限位壁，所述纵向限位壁与所述纵向限位梁形成贴邻连接，所谓贴邻连接，指的是纵向限位梁与纵向限位壁之间、在横向方向上呈贴合状态。
 有益效果
通过对现有技术的上述改进，本发明达到的有益效果如下：由于将弹性簧片上的压簧片冲压成型而分解成接触簧片以及分布于于接触簧片两侧的压片，当推起手柄的推板时，便可促使压板对压片进行下压，进而带动接触簧片随之向下变形，然后将导线直接插进进线孔和出线孔，再松开手柄便可，本领域技术人员应该知晓，本说明书中手柄的压板不是直接对接触簧片进行下压，而是通过对接触簧片两侧的压片进行下压，进而带动接触簧片随之变形，这样的结构可有效避免因人为因素（比如工作人员过分大力的推动手柄）使弹性簧片产生永久破坏性变形，即当工作人员因过分大力推动手柄的推板时，充其量也只是使压片变形难以恢复原状，而接触簧片却不至于因此而受到破坏性变形，因此，采用接触簧片的间接变形这样的结构对接线端子的使用寿命有极大的提升，其接线的可靠性和平稳性也体现的淋漓尽致。

如图1-图8所示，本实施例涉及一种快速连接免螺丝接线端子，图1结合图4明显可知，该接线端子包括手柄3、卡接于一体的上盖2和底座1以及设置于该接线端子内腔的导电板4、弹性簧片5，本实施例中，所述上盖2和底座1的卡接结构具体描述如下：图4和图8显示，所述上盖2上具有向下延伸的卡板20，所述卡板20上具有楔形卡接部200，图7中进一步显示，所述底座1的前后两侧壁上、与所述楔形卡接部200相对应的位置形成卡接孔 10，所述上盖2与底座1通过所述楔形卡接部200与卡接孔10的卡接连接而形成一体式结构；图 1中明显显示，所述手柄 3铰接于所述上盖 1上，图 3中显示，所述上盖 2的横向两侧分别开设有进线孔 21和出线孔 22，图 6中显示，所述弹性簧片 5具有定位板 50和从所述定位板 50的横向两侧边沿呈斜向上延伸的压簧片 51，所述压簧片 51上、靠近顶端位置具有冲压成型的接触簧片 510，所述接触簧片 510的两侧形成压片 511，图 2结合图 5显示可知，所述手柄 3具有推板 30以及从所述推板 30其中一端的前后两侧边沿位置、呈斜向下延伸的压板 31，结合图 3所示可知，所述压板 31与所述压片 511形成抵接，所述接触簧片 510与所述导板4形成抵接；本实施例中，所述手柄3与所述上盖2之间的铰接结构具体描述如下：图5中显示，所述压板31的外侧面上形成柱形凸缘310，图8中显示，所述上盖2的上端面上开设有纵向开口23，所述纵向开口23的前后两侧壁形成纵向适配槽230，所述手柄3通过所述柱形凸缘310与所述纵向适配槽230的适配而形成与上盖2之间的铰接连接。
本实施例中，图 3结合图 7明显可知，为了使弹性簧片 5能有效的被限位在底座 1上，在所述底座 1上、位于定位板 50横向两侧边沿的位置具有用于限制弹性簧片 5横向偏移的限位横梁 11，所述定位板 50前后两侧边沿、靠中间位置形成内凹的定位槽 500，所述底座 1上、与所述定位槽 500相对应的位置形成与所述定位槽 500适配的纵向限位板 12，通过限位横梁 11和纵向限位板 12的设置，使得弹性簧片 5在横向方向上和正向方向上都被有效的限位，进一步保证了接线的可靠性。同时，图 3和图 4中显示，在本实施例中，为了避免引进进线孔 21和出线孔 22的导线在接线端子内腔接触，特意在所述导电板 4的靠中间位置设置了冲压成型的纵向隔板 40。
本实施例中，所述手柄 3上、靠近所述压板 31的位置具有从所述推板 30上纵向向下延伸的纵向限位梁 301，所述导电板 4上、靠近所述纵向限位梁 301的位置具有垂直于所述导电板 4延伸的纵向限位壁 41，图 3中明显显示，所述纵向限位壁 41与所述纵向限位梁 301形成贴邻，通过该附图 3可知，所谓贴邻，指的是纵向限位梁 301与纵向限位壁 41之间、在横向方向上呈贴合状态。另外，图 1结合图 2和图 7显示可知，所述底座 1的其中一侧壁上具有凸出的、横截面成梯形结构的纵向插接板 13，该底座 1上与所述纵向插接板 13相对应的另一侧壁上具有内凹的、横截面成梯形结构的纵向插接槽 14，所述纵向插接板 13与所述纵向插接槽 14适配；该结构的设置可有效的将多个本实施例的接线端子进行插接并联而形成端子排，在实际使用中极大地满足了方便大量接线的要求。
本实施例中，由于将弹性簧片 5上的压簧片 51冲压成型而分解成接触簧片 510以及分布于于接触簧片 510两侧的压片 511，当推起手柄 3的推板时 30，便可促使压板 31对压片 511进行下压，进而带动接触簧片 510随之向下变形，然后将导线直接插进进线孔 21和出线孔 22，再松开手柄 3便可，本领域技术人员应该知晓，本实施例中手柄 3的压板 31不是直接对接触簧片 510进行下压，而是通过对接触簧片 510两侧的压片 511进行下压，进而带动接触簧片 510随之变形，这样的结构可有效避免因人为因素（比如工作人员过分大力的推动手柄 3）使弹性簧片 5产生永久破坏性变形，即当采用本实施例中的将压簧片 51设置成压片 511和接触簧片 510的结构之后，如果工作人员因过分大力推动手柄 3的推板 30时，充其量也只是使压片511变形难以恢复原状，而接触簧片 510却不至于因此而受到破坏性变形，因此，采用接触簧片 510的间接变形（而不是直接由压板 31作用到接触簧片 510上）这样的结构对接线端子的使用寿命有极大的提升，其接线的可靠性和平稳性也体现得淋漓尽致。
实施例 2：
图 9-图 12显示为实施例 2的具体结构，该实施例与实施例 1的主要区别在于：实施例 1是一进一出的横向两侧的接线方式，而实施例 2是同向的接线方式，即实施例 2中进线孔 21和出线孔 22设置在接线端子的同一侧，因此，从整体结构而言，其与实施例 1的主要区别便体现在弹性簧片 5和底座 1及上盖 2上，本领域的技术人员通过结合其中的图 10、图 11和图 12显示可知，实施例 2中的导电板 4多了个连接板 42将进线孔 21和出线孔 22方向的导电部分进行了一体式连接，取消了纵向隔板 40的设置，从而形成了整体的导电板 4，相应的，弹性簧片 5也是同样的进行了同向并联连接，以至于相应的底座 1和上盖 2都进行了相应的结构调整，而这种调整却是实施例 1技术方案的精神延伸，通过图 9-图 12明显可知的，因此，对于本领域的技术人员而言，实施例 2的接线端子整体结构的装配方式与实施例 1的原理相同，不影响理解便可。
另外，通过图 9明显可知，实施例 2与实施例 1之间还有一个显著的区别在于：实施例 1的上端面中间位置开设有一个用于电工测试通电与否的测试孔 24，这种单独开设一个测试孔 24的设计在现有技术中也是极为常见的，属于本领域技术人员的公知常识，然而实施例2中的图 9中显示，采用手柄 3和上盖 2之间在横向方向上刻意留出来的足够大的间隙作为测试孔 24，即实施例 2中的接线端子考虑到产品整体外观的精致美观等效果，特意从设计入手，将该测试孔 24设计进装配特征里面，而不是刻意在壳体 1上开设一个测试孔，体现了其设计之巧妙。
