实施例一
如图1和2所示，本实施例1提供一种穿线密封箱，用于对线缆接线头进行安装防护。该穿线密封箱包括箱体1和穿线组件2，箱体1上设置有开口，方便在箱体1内进行接线等操作，箱体1的侧壁上设置有安装槽11，安装于应用场景时，安装槽11通常位于箱体1底部。穿线组件2包括穿线板组件21和穿线体22，穿线板组件21滑动设置于安装槽11内，以滑入或滑出安装槽 11，穿线板组件21上设置有穿设孔212，穿线体22设置于穿线板组件21上，并位于箱体1的外侧，穿线体22与穿设孔212相连通，穿线体22能够将穿过穿线体22的线缆周向密封，有效降低漏水风险，无需再使用防水端子等配件对线缆进行锁紧，操作简单，而且安装空间小，相同空间内可安装更多的线缆，有效降低线缆接线成本；当需要维护拆卸时，可将穿线组件2沿安装槽11移出箱体1外，无需抬升机器即可取出线缆，减少搬抬操作，节省人力成本。
如图1所示，为了对箱体1进行密封，穿线密封箱还包括盖板31，盖板31盖设在箱体1的开口处。具体地，盖板31的一端与箱体1的未设置安装槽11的一个侧壁铰接，以能够实现打开或盖合穿线密封箱。盖板31相对箱体1内部的一侧设置有密封件32，盖板31盖合在箱体1后，密封件32填充于盖板31和箱体1的侧壁之间，对箱体1进行密封，防止穿线密封箱进水进尘。其他实施例中，盖板31并不限于与箱体1相铰接，盖板31可以直接盖设在箱体1上，或者由箱体1上取下。
需要注意的是：在进行接线操作时，需要将盖板31开启一定的角度，为了操作方便及安全，设置定位结构将盖板31固定在需要的位置。
具体而言，在盖板31上设置第一定位板33，第一定位板33沿盖板31的宽度方向设置多个第一定位孔331；在箱体1内对应设置有第二定位板12，第二定位板12的端部设置有第二定位孔121，另外设置有定位销34，定位销34的一端插入第二定位孔121，根据盖板31的开合程度，定位销34的另一端插入对应的第一定位孔331。通过定位销34与第一定位孔331和第二定位孔121插接配合，将盖板31固定在一定的开合位置，从而方便操作者进行接线操作及防止盖板31晃动对操作者造成伤害。当需要调节盖板31的开合角度时，可 以调整定位销34的另一端与不同第一定位孔331的插接配合。
下面结合图1和图2对穿线板组件21的结构进行描述，如图1所示，穿线板组件21包括穿线板本体211和穿设孔212，如图2所示，穿线板本体211滑动设置于安装槽11内，穿线体22设置于穿线板本体211上，并完全盖设住穿设孔212。
优选地，穿线板组件21上设置多个穿设孔212，每个穿设孔212均对应设置一个穿线体22，每个穿线体22上可穿过一根电缆。本实施例中，如图3所示，穿线板本体211上设置有五个大小相同的穿设孔212，对应设置的五个穿线体22的大小也相同；当然，也可设置多个穿线体22中的至少两个穿线体22的靠近穿线板组件21的一端的直径不同，穿线体22的靠近穿线板组件21的一端的直径大于对应的穿设孔212的直径，如图4所示，穿线体22的数量设置为三个，三个穿线体22的大小均不同。当然，可根据穿线板本体211及穿线体22的大小合理设置穿线体22的数量，穿线体22的数量及大小不受限制。
为了使单个穿线体22可适应多个线径的线缆，如图1所示，穿线体22设置为圆锥形，由靠近穿线板本体211的一端向远离穿线板本体211的一端逐渐收拢并在端部闭合形成密封端，穿线体22与穿线板本体211之间形成密封。穿线时，根据需要穿线的直径大小，将对应的穿线体22的密封端戳破或剪开，剪开的孔径略小于线缆的直径，使线缆由剪开的孔径穿入，实现穿线体22对线缆的包覆，其中穿线体22可采用具有弹性的材质，如橡胶。
优选地，如图3和图4所示，穿线体22的外周设置有锁线圈23，锁线圈23在穿线体22的外壁上向外凸出而成，锁线圈23具有弹性，能够加强对线 缆的锁紧强度，防止过度撕裂。穿线体22上还设置有锁线圈23适用的线径大小范围的标识，使用者可根据线缆的直径要求沿着相应的锁线圈23的上缘剪掉，当线缆穿入时，锁线圈23将对线缆进行抱紧，对线缆具有一定的保持力，从而达到密封防护。
具体而言，锁线圈23设置有至少两个，所有锁线圈23沿穿线体22的轴向分布，也就是能够根据不同的线缆直径而选择由穿线体22的不同位置剪开，不同的锁线圈23可以对不同线径进行锁紧密封。
针对每个锁线圈23适用的线缆直径范围做了标识，如图3所示，穿线板本体211上设置有五个大小一致的穿线体22，每个穿线体22上设置有三个锁线圈23，可适用线缆直径L的范围为：14mm＜L≤32mm，具体地，直径最小的锁线圈23适用的线缆直径L的范围为14mm＜L≤24mm，中间的锁线圈23适用的线缆直径L的范围为24mm＜L≤32mm，通常直径最大的锁线圈23无需剪开，起到加强穿线体22支撑强度的作用，当然也可以根据需要从直径最大的锁线圈23的上缘剪开，从而扩大穿线体22的适用的线缆直径范围，也能够达到锁线圈23对线缆的锁紧密封作用。在穿线板本体211上设置的穿线体22的大小不同时，与穿线体22大小一致时的作用原理相同。如图4所示，在穿线板本体211上设置有三个大小不同的穿线体22，其中，最大的穿线体22上设置有四个锁线圈23，可适用线缆直径L的范围为40mm＜L≤75mm，各锁线圈23适用的线缆直径L的范围分别为40mm＜L≤50mm、50mm＜L≤65mm以及65mm＜L≤75mm，另一穿线体22上设置有三个锁线圈23，各锁线圈23适用的线缆直径L的范围分别为15mm＜L≤24mm以及24mm＜L≤32mm，最小的穿线体22上设置有三个锁线圈23，各锁线圈23适用的线缆直径L的范 围分别为8mm＜L≤13mm以及13mm＜L≤18mm。需要说明的是，锁线圈23的设置数量和适用的直径范围并不受以上限制，根据实际需要设置即可。
进一步地，如图5所示，穿线组件2还包括密封套24，密封套24设置于穿线板组件21上，并位于箱体1的内侧，密封套24与穿线体22对应设置，且与穿线体22相连通，密封套24的口径由靠近穿线板组件21的一端向远离穿线板组件21的一端逐渐减小。密封套24对线缆进一步锁紧密封，使线缆更加密封稳固。密封套24采用如橡胶的弹性材质制作，锁紧密封效果更好。在其他实施例中，也可以将穿线体22设置于箱体1的内侧，而将密封套24设置于箱体1的外侧，同样能够实现对线缆的锁紧密封作用。
进一步地，穿线板本体211包括穿线板本体骨架和包覆层，包覆层包裹在穿线板本体骨架的外表面，包覆层与穿线体22和密封套24一体成型。一体成型的结构设计使穿线体22和密封套24与包覆层之间的连接更加牢固，而且无需其他结构件进行组装，操作更加方便。
进一步地，如图1所示，在箱体1内设置有两个连接件13，连接件13位于安装槽11的两侧，连接件13端部设置有第一螺纹孔，穿线板本体211的朝向箱体1内一侧的上端设置有两个凸台214，凸台214上设置有第二螺纹孔，穿线组件2安装到安装槽11后，第一螺纹孔和第二螺纹孔同轴对齐；盖板31的内侧对应设置有凸起35，凸起35上设置有第三螺纹孔，盖板31盖合时，第一螺纹孔、第二螺纹孔和第三螺纹孔形成直径大小一致的螺纹腔，从箱体1外侧使用螺栓或螺钉拧进螺纹腔，从而实现将盖板31固定在箱体1开口处，实现对箱体1的密封，同时将穿线组件2固定在安装槽11内，防止其滑动而影响线缆接头的稳定性。在凸台214和凸起35之间还设置有垫圈215，可防 止凸台214和凸起35直接接触产生磨损，并起到一定的密封作用。
实施例二
如图6-图7所示，本实施例提供一种穿线密封箱，其与实施例一的不同之处在于本实施例中，穿线板组件21的结构不同。实施例一中，穿线板本体211滑动设置于安装槽11内。而本实施例中，如图6所示，穿线板组件21包括安装板213和穿线板本体211，安装板213滑动设置于安装槽11内，如图7所示，安装板213上设置有过孔2131；穿线板本体211安装于安装板213上，并与过孔2131对应设置，穿线体22设置于穿线板本体211上。穿线体22和密封套24与过孔2131对应设置，以使线缆能够穿过穿线体22、密封套24和过孔2131而伸入箱体1内。
具体而言，安装板213和穿线板本体211上设置有螺纹孔，通过螺钉连接将安装板213和穿线板本体211连接在一起，当然也可以采用其他方式连接，能够将安装板213和穿线板本体211紧密连接起来即可，不以为限。
进一步地，安装板213和穿线板本体211均包括包覆层，包覆层由橡胶等弹性材质制成，安装板213和穿线板本体211压合在一起时，包覆层起到密封作用。
本实施例提供的穿线密封箱，只需要更换具有不同尺寸的穿线体22的穿线板本体211即可满足不同尺寸的线缆，无需更换安装板213，有效降低生产成本。
显然，本发明的上述实施例仅仅是为了清楚说明本发明所作的举例，而并非是对本发明的实施方式的限定。对于所属领域的普通技术人员来说，能够进行各种明显的变化、重新调整和替代而不会脱离本发明的保护范围。这里无需 也无法对所有的实施方式予以穷举。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，均应包含在本发明权利要求的保护范围之内。
