Description
本发明属于连接设备领域，尤其涉及一种接线器。
在电线布线改装时经常会碰到需要把电线切断，再重新接起来的情况。
传统的连接方式是剪断电线后，再剥离电线外面的线皮，把需要连接的线芯拧在一起，再用热缩套管套紧，由于热缩套管需要使用额外的热吹风设备，操作复杂。
比较好的连接方式是在剥线后，使用奶嘴式的接线端子压紧，或者用螺丝帽式接线端子拧紧，或者用快速接线端子接起来。
无论采用上述哪一种连接方式，不但需要剪线剥线，操作步骤多，剥线后大量的线皮碎屑需要清理，耗费的人工工时长，而且接线过程中会有裸露的线芯，如果忘记断开电源开关或者有人意外打开了电源开关，就会给操作人员带来触电的危险。

所述端盖20和所述底座10均由绝缘材料制成，底座10或端盖20上设置有硬质导电片40，底座10或端盖20上设置有切线片50。在端盖20盖合所述底座10时，电线30被压紧于切线片50，切线片50把电线30一分为二的切断。硬质导电片40同时划破电线30的绝缘皮，使得线芯与硬质导电片40相接触。这样，硬质导电片40就把与其接触的电线30重新电连接起来。这种连接方式无需对电线30进行剥线和使用额外的工具，整个接线过程简单、高效。
进一步地，所述底座10上开设有至少两条贯通其两端端面并供所述电线30穿设的接线槽11，所述接线槽11的槽宽与所述电线30的线宽之比为0.95～1.05。具体地，接线槽11可以为方槽、半圆槽或者V型槽，本实施例中所述接线槽11为方槽。
进一步地，所述底座10上开设有容置槽13，所述容置槽13的槽深大于所述接线槽11的槽深，所述切线片50安置于所述容置槽13的槽底。所述端盖20上间隔凸设有两条压线骨部21，两条所述压线骨部21在所述底座10和所述端盖20盖合时置于所述容置槽13内且分别位于所述切线片50的两侧。所述压线骨部21与邻近的所述容置槽13的槽壁之间的间距大于或等于所述电线30的线宽。在所述压线骨部21压入所述容置槽13后，所述电线30被所述切线片50切断后，形成的两端被压线骨部21压服于所述容置槽13的槽壁上。这样，电线30被完成分离成两根互不电接触的电线。
进一步地，所述压线骨部21的底部的水平位与所述切线片50的片尖的水平位之间的位置差大于所述电线30的线宽，从而使电线30被切断后的断头，有足够的空间被相应的压线骨部21压服于容置槽13的槽壁上。
请同时参阅图4至图6，所述压线骨部21的两端均开设有用以引导所述压线骨部21压入所述容置槽13内的第一引导面23。所述第一引导面23朝压线骨部21的中心部位倾斜，以便在端盖20盖合底座10时，引导压线骨部21准确快速压入所述容置槽13内。
进一步地，所述底座10上还开设有两条固定槽12，所述容置槽13位于两条所述固定槽12之间，至少有一个所述固定槽12内设置有至少一片所述硬质导电片40，各所述硬质导电片40于所述固定槽12内线性排列且间隔设置。所述固定槽12和所述容置槽13的布置路径均与所述接线槽11的布置路径交错设置。优选地，本实施例中接线槽11基本垂直所述容置槽13和所述固定槽12。
固定槽12内硬质导电片40的数量可以根据实际需求来设定，当切线片50两侧电线30均需要电连接时，可以在固定槽12内均设置一块硬质导电片40。也可以只在一个固定槽12内设置硬质导电片40，另一固定槽12内不设置硬质导电片40。各个固定槽12内也可以设置多个硬质导电片40，多个硬质导电片40在固定槽12内呈线性排列且彼此独立不相电接触。
进一步地，所述硬质导电片40于与所述接线槽11对应的位置开设有供所述电线30穿过且于电线30的径向方向割破其所述绝缘皮的凹槽41，所述凹槽41的宽度小于所述电线30的直径。硬质导电片40上凹槽41的数量由实际需要电连通的电线30的数量决定。比如两连通硬质导电片40，在该硬质导电片40上开设有两个凹槽41，可以电连通两根电线30，依此类推。
进一步地，所述凹槽41的开口处开设有呈外扩状且用于引导所述电线30卡入所述凹槽41的第二引导面42。端盖20盖合底座10时，电线30在端盖20压力的作用下向凹槽41内压紧电线30，电线30沿第二引导面42滑入凹槽41，由于凹槽41的槽宽小于电线30的线宽，因此凹槽41两侧的槽壁同时对滑入凹槽41内的电线30进行切割。随着电线30滑入至凹槽41的槽底，电线30外周的绝缘皮被凹槽41的槽壁划破，裸露的线芯与凹槽41两侧的槽壁相电接触，从而让硬质导电片40把穿过其的电线30重新电连接在一起。
所述端盖20上沿所述接线槽11的延伸方向上间隔布置有若干用以将所述电线30压入所述凹槽41内的压线块22。为了使电线30充分卡入凹槽41内，端盖20可以沿电线30的延伸方向上设置若干压线块22，压线块22在端盖20盖合底座10时，能充分压紧电线30于接线槽11和凹槽41内，从而保证电线30与硬质导电片40充分电接触。
进一步地，所述底座10于所述接线槽11的槽口处均设置有用以径向固定所述电线30且呈倒钩状的线扣14，所述线扣14成对布置于所述接线槽11的槽口，所述接线槽11的槽口位于相对应的两个所述线扣14之间。接线槽11两端的线扣14可以防止电线30滑入接线槽11和凹槽41后的径向位移，避免电线30滑出接线槽11。
进一步地，所述线扣14上还开设有用以引导所述电线30卡入所述接线槽11内的第三引导面141。所述端盖20位于所述接线槽11两侧的所述线扣14之间。所述第三引导面141可以引导电线30从线扣14处顺利卡入接线槽11内，从而使端盖20盖合所述底座10且位于接线槽11两侧的线扣14之间。
进一步地，所述端盖20的一端与所述底座10枢转连接，所述端盖20的另一端与所述底座10卡扣连接，所述端盖20与所述底座10卡扣连接的一端上设置有横截面呈倒钩状的第一扣部24，所述底座10的外侧壁上朝外凸设有与所述第一扣部24形状互补的第二扣部15。优选地，端盖20与底座10的枢转连接可以为铰链连接，也可以通过柔性连接件可转动的将端盖20与底座10连接起来。第一扣部24与第二扣部15在端盖20盖合底座10时互相钩住，从而是端盖20与底座10卡扣连接为一体。
进一步地，所述第一扣部24上开设有引导所述第一扣部24扣入所述第二扣部15的第四引导面25。
进一步地，所述第二扣部15上开设有引导所述第一扣部24扣入所述第二扣部15且形状与所述第四引导面25相适配的第五引导面151。
第四引导面25与第五引导面151可以使第一扣部24与第二扣部15顺利卡扣连接，提高端盖20与底座10的盖合效率。
请同时参阅图7至图9，根据所述接线器100，列举不同数量的接线槽11以及不同片数的硬质导电片40组合使用的情况，以便更好理解和解释本发明，但并不只限于以下几种情况：
图7列举的接线槽11的数量为2，两个接线槽11中分别放置电线a-b和电线c-d，其中一固定槽12内设置有一片两连通硬质导电片40，另一固定槽12内没有设置硬质导电片40。在端盖20盖合底座10后，电线a-b和电线c-d被切线片50切断为a段、b段、c段与d段，在硬质导电片40的电连接下，重新连接成为电线a-c。
图8是在图8的基础上再增加了一条电线e-f，两个固定槽12内均放置了一片三连通硬质导电片40。在端盖20盖合底座10后，切线片50把三根电线切断为a段、b段、c段、d段、e段和f段，在硬质导电片40的电连接下a段、c段和e段重新电连接，b段、d段和f段重新电连接。
图9是在图8的基础上再增加了两条电线，分别是电线g-h和电线i-k，一个固定槽12内设置了一片五连通硬质导电片40，另一固定槽12内设置了一片两连通硬质导电片40和一片三连通硬质导电片40，两连通硬质导电片40和三连通硬质导电片40彼此隔开。在端盖20盖合底座10后，切线片50把五根电线切断为a段、b段、c段、d段、e段、f段、g段、h段、i段和k段，在五连通硬质导电片40的电连接下a段、c段、e段、g段和i段电连接在一起，在两连通硬质导电片40的电连接下b段和d段电连接在一起，在三连通硬质导电片40的电连接下f段、h段和k段连接成一体。
请同时参阅图10，列举了将传统日光灯61灯盘线路改装成LED灯62的灯盘线路。即将安装有两支日光灯61的灯盘中的线路，改装成双端供电的LED灯管62的线路。当L输入端（火线）和N输入端（零线）分别连接在LED灯管62的两端时，LED灯管62开始工作。该灯盘线路的改装，使用两个接线器100就可以改装成功。
所使用的接线器100的接线槽11数量为三，仅在接线器100的一个固定槽12内使用一片开设有三个凹槽41的硬质导电片40。将原镇流器60上的L端以及原日光灯61上的t端和y端连接在一个接线器100的硬质导电片40上，再将原镇流器60上的N端以及原日光灯61的s端和x端连接在另一个接线器100的硬质导电片40上。
分别盖合两个接线器100的端盖20，即可完成线路改装。使得L端和N端直接给LED灯管62供电，并且断开镇流器60的线路。类似地，当灯盘安装的日光灯数量为n时，改装灯盘线路时所使用的接线器100的接线槽11数量为n+1以及使用一片开设有n+1个凹槽41的硬质导电片40。
以上所述仅为本发明的较佳实施例而已，并不用以限制本发明，凡在本发明的精神和原则之内所作的任何修改、等同替换和改进等，均应包含在本发明的保护范围之内。
