实施例：如图2-6所示，一种新型绝缘密封插盒，包括盒体10和固定夹20，所述盒体10内设有若干相互间隔的插孔11，且所述盒体10的上表面沿轴向方向延伸形成支撑臂12，所述支撑臂12上设有若干相互间隔的插槽13，安装时，电磁线41和线束导线42插入所述插孔11，且所述电磁线41和线束导线42伸出插孔11的部分置于所述插槽13内，所述固定夹20用于固定插槽13中的电磁线41和线束导线42，所述插盒通过所述固定夹20固定于电机定子上。盒体中根据需要设有若干插孔，本实施例以常用的三个插孔11为例，三相电设有三束线束导线42，各相线束导线42与相应的线圈输出电磁线分别用端子焊接后插入一插孔11中，相邻插孔之间的隔栏具有足够的厚度以保证绝缘效果，因此各相线束导线42分别被放置在不同的插孔中，可以避免相与相之间短路的发生，起到相互绝缘的作用；电磁线41和线束导线42通过固定夹20固定后， 整个插盒又通过固定夹20固定于电机定子上，使用非常方便。

如图2所示，所述固定夹20包括固定连接的夹紧部21以及固定部22，所述固定部22上设有安装孔，所述夹紧部21套设于支撑臂12而将支撑臂上的电磁线41和线束导线42夹紧，所述固定部22利用固定螺柱穿设于安装孔内而将所述插盒固定于电机定子上。夹紧部21呈内部中空的环形结构以便于套设于支撑臂12和绝缘套管30，其内部中空的尺寸以刚好夹紧支撑臂12和绝缘套管30为准，固定部22固定连接于夹紧部的一侧，且固定部为片状结构，通过固定螺栓穿过固定部的安装孔而将插盒锁紧于电机定子的铁芯上。
如图2所示，所述插槽13位于所述支撑臂12的正面，所述支撑臂12的背面设有凹槽16，所述夹紧部21卡入所述凹槽16内，所述凹槽16的宽度大于等于所述夹紧部21的宽度。在支撑臂12上设有凹槽16，凹槽的尺寸，如深度、宽度和长度皆可根据固定夹的尺寸来进行调整，凹槽16的宽度以略大于夹紧部21的宽度为佳，便于夹紧部卡入凹槽16内，且夹紧部21刚好顶紧于凹槽16的上下两端，从而限制固定夹在盒体上串动而引起发生盒体脱落的现象。
本申请的安装过程：
步骤1：以三相电的应用为例，根据实际需求，盒体10上设有三个插孔11，首先分别将每相线束导线42与相应的线圈输出电磁线41用端子焊接，并分别放入三个插孔11内，利用插孔之间的隔栏14将每项导线相互隔开，避免相与相之间短路，起到了相互绝缘的作用；
步骤2：然后往插孔11内注入耐高温机油的硅胶，冷却凝固后形成密封胶体40，密封胶体40填满于整个插孔而将整个线束导线头部包裹密封，使空气无法进入导线的线芯及胶皮内，从而当将具有所述插盒的定子装在发电机内部时就可以避免发动机机油通过导线线芯之间、线芯与胶皮之间的空隙流到发动机外，起到了密封的效果；
步骤3：分别将三个绝缘套管30套设于三个插孔外的线束与电磁线上，避免固定夹20固定时损伤导线胶皮及电磁线导致其与固定夹接触发生短路现象，再将固定夹的夹紧部21套设于支撑臂12与绝缘套管30上，夹紧部将绝缘套管30夹紧，最后利用固定螺栓锁紧于固定夹的固定部22，而将装配好线束的插盒固定在电机定子的铁芯上，如图2所示，完成整个装配作业。
应当指出，对于本领域的普通技术人员来说，在不脱离本申请构思的前提下，还可以做出若干变形和改进，这些都属于本申请的保护范围。因此，本申请专利的保护范围应以所附权利要求为准。
