该线性驱动器包括壳体1，安装在该壳体1内的马达40、蜗杆组件、由该蜗杆组件驱动的推杆组件、电路板50、用于限制推杆组件行程的限位开关以及驱动该蜗杆组件的马达40。

本实施例中，该线性驱动器的壳体1上只需设置插接窗口273，在壳体1内部将内部接线集中在连接座52上以简化装置内部布线设计，同时通过电气接头60将所有的外置线集束成统一的线材并实现线材外置，在具体应用该线性驱动器到不同设备时，可以根据设备的具体要求通过简单方便插拔即可更换不同线材。
同时该壳体1内设置的电路板50上集成一个作为线材母座的连接座52，该连接座52对应位于该插接窗口273处，以方便连接该电气接头60。
如图7所示，该电气接头60包括本体61以及设置在本体61内并具有连接端子的驱动座62，该驱动座62连接外置线材70。该外置线材70为设置于线性驱动器壳体外部的电气线。该本体61上设置装饰外壳，该装置外壳的外形与线性驱动器的壳体1的整体设计保持一致和协调性。

为了便于组装，该壳体1包括第一外壳10与第二外壳20，该第一外壳10与第二外壳20上对应设置预安装结构。该第一外壳10的一端形成第一半圆槽15，该第二壳体20的对应该半圆槽15设置第二半圆槽25。该第一半圆槽15与第二半圆槽25合围成供推杆组件做线性运动的壳体出口。
请一并参考图2，该预安装结构包括相互配合的若干对卡槽与扣榫，该第一外壳10上设置该若干卡槽，如图3所示，卡槽11、卡槽12、卡槽13、卡槽14以及卡槽18。该第二外壳20上设置若干对应卡槽的扣榫，如图3所示，与卡槽11配合的扣榫21以及与卡槽12配合的扣榫22等。为了锁紧壳体1，该第一外壳10上还设置螺孔，比如螺孔16。该第二外壳20上对应该螺孔16设置安装孔26。通过卡槽与扣榫完成预安装以后，螺钉261穿过该安装孔锁入该螺孔16，从而锁紧该第一外壳10与该第二外壳20，该插接窗口273开设在该第一外壳10或者第二外壳20上。
本实施例中，为了实现简单快捷的壳体1安装，该第一外壳10与第二外壳20的由卡槽和扣榫配合完成快速预安装，再通过螺钉261将该第一外壳10与第二外壳20锁紧在一起，内壁均设置卡扣结构使两个壳体卡扣式扣合，再通过一颗螺钉261将两个壳体进一步锁止固定，改变现有的多个螺钉组合多个螺钉槽的复杂锁紧结构，优化了壳体安装结构使得线性驱动器的生产工艺简化，成本降低。

请一并参考图4与图5，在该动力外壳上靠近插接窗口273处设置有线材收纳机构。本实施例中，该线材收纳机构包括设置在该动力外壳上的线材收纳部206以及绕线柱207。线性驱动器不使用时，拔下的电气接头60可卷绕在该线材收纳机构上。具体使用时，该电气接头60的外置线材70折叠穿过该线材收纳部206并卷绕在该绕线柱207上。
该蜗杆组件包括一体成型的斜齿轮31以及蜗杆32，该马达40的输出连接至马达轴42，该斜齿轮31与该马达轴42啮合。
作为蜗杆组件的实施例，为了减少工序和成本，该斜齿轮31与该蜗杆32为一体成型的塑胶件。本实施例中，该蜗杆32与蜗杆32一端的斜齿轮31采用一体成型工艺制成，形成塑胶蜗轮蜗杆结构，该一体式塑胶蜗轮蜗杆结构适用于小力度线性运动应用场景，蜗杆32与斜齿轮31的一体成型工艺一方面可减少制作工艺过程，另一方面也能保证蜗杆32与蜗轮33，斜齿轮31与马达轴42之间的结构稳定。并且一体成型的塑胶蜗杆32和斜齿轮31结构在小力度线性运动应用场合在保证工作稳定性的同时可降低线性驱动器的成本。

该推杆34中空用以安装该蜗杆32和蜗轮33，并为蜗轮33的线性运动提供行程空间。为了扩展该线性驱动器与相关部件的连接，该推杆34自由端开设安装槽，形成连接部341。该连接部341设置用于枢转连接扩展部件的铆接件342。
为了扩展相关部件，该安装外壳的在远离推杆靠近马达40的一端设置预定位件，如图3所示，形成在该第一外壳10末端的凸边292以及形成在该第二外壳20末端的凸边293，该预定位件上可拆卸固定安装部29。

本实施例的线性驱动器，壳体1内的电气器件的电路走线集中布设在电路板上，通过在电路板上增设连接座52，连接端子集中至连接座52，壳体1上设置插接窗口273，使所有的线材外置，在将线性驱动器应用到特定设备时，可根据具体设备要求方便地更换线材。通过插接单个的电气接头60即可完成线材的调整和更换使用方便。同时该电气接头60的设置可减少壳体1开设的接口，将原有的多个接口整合为仅需开设单一插接窗口273，使得线性驱动器在便于使用的同时更简洁美观。
综上，本实施例的线性驱动器，为了实现简单快捷的壳体1安装，该第一外壳10与第二外壳20的由卡槽和扣榫配合完成快速预安装，再通过螺钉261将该第一外壳10与第二外壳20锁紧在一起，内壁均设置卡扣结构使该第一外壳10与第二外壳20卡扣式扣合，再通过一颗螺钉261将两个壳体进一步锁止固定。并且，该线性驱动器的壳体1上只需设置插接窗口273，在壳体1内部将内部接线集中在连接座52上以简化装置内部布线设计，同时通过电气接头将所有的外置线材70集束成统一的线材实现线材外置，在具体应用该线性驱动器到不同设备时，可以根据设备的具体要求通过简单方便插拔即可更换不同线材。另外，该壳体1内设置的电路板50上集成一个作为线材母座的连接座52，该连接座52位于该插接窗口273后方，方便快速插接该电气接头60。同时，该壳体1设置的安装部29作为零部件配备了不同型号可拆卸可更换，便于线性驱动器的推广应用。该插接窗口273上有多个用于导向和限位的限位肋272用于与电气接头上的卡扣601和卡扣602一起固定该电气接头。进一步地，该蜗杆和蜗杆前端的斜齿轮为一体成型的塑胶件，结构稳定；蜗杆和斜齿轮一体成型的结构可减少一个零部件的制作并且在在小力度线性运动应用场合，线性驱动器的传动功能和传动性能不变，而且金属件换成塑胶件使得线性驱动器的成本降低。
