下面结合附图和实施例，对本申请的具体实施方式作进一步详细描述。以下实例用于说明本申请，但不用来限制本申请的范围。
本申请固线扣的较佳实施例的一种，请参照图1至图3所示，固线扣1包括底座10，底板10设有供输入线穿过的过线孔11，过线孔11的形状为圆形，过线孔11也可以不限于圆形。底板10的第一表面102设有沿过线孔的外侧周向间隔排列的多个第一干涉部12和多个第二干涉部13。底座10的第二表面103为倾斜斜面，安装后美观，不伤人。第一干涉部12和第二干涉部 13的数量优选为三个以上，如图3所示，本实施例中，第一干涉部12和第二干涉部13均为三个。三个第一干涉部12和三个第二干涉部13均沿过线孔11的外侧周向均匀排列，第一干涉部12和第二干涉部13间隔交错排列。第一干涉部12包括自底板10的第一表面102延伸出且与第一表面102形成角度的第一弹性体121和自第一弹性体121远离过线孔11一侧的外侧表面延伸突起的第一钩体122。第二干涉部13包括自底板10的第一表面102延伸出且与第一表面102形成角度的第二弹性体131和自第二弹性体131靠近过线孔11一侧的内侧表面延伸突起的第二钩体132。本实施例中，第二干涉部13延伸出第一表面102的高度大于第一干涉部12延伸出第一表面102的高度，第一干涉部12高度与对应的壳体3厚度相适应，第二干涉部13的高度与固线凸环211相适应。
如图4-6所示，为本申请的使用状态，固线扣1与输入线2、壳体3配合使用，以将输入线2固定在壳体3上。输入线2包括绝缘表皮21和由绝缘表皮21包覆的导线22，输入线2的绝缘表皮21设有固线凸环211，固线凸环211在输入线2的绝缘表皮21外经过二次注塑加工形成。本实施例中，先将输入线2的一端自固线扣1设有第二干涉部13的一侧表面插入且穿入过线孔11，挤压第二干涉部13，使第二干涉部13的第二弹性体131发生变形向外侧张开，固线凸环211卡入多个第二干涉部13形成的空间中且固线凸环211被限位于第二钩体132与底板10的表面之间，即固线凸环211被夹持在多个第二干涉部13围成的空间中，实现输入线21与固线扣1之间的固定。壳体 3设有固线通孔31，将输入线2的另一端穿过固线通孔31，固线通孔31挤压第一干涉部12，使第一干涉部12的第一弹性体121变形向内压缩，第一干涉部12插入固线通孔31中，第一干涉部12恢复原状，壳体3被限位于第一干涉部12的第一钩体122与底板10的表面之间，即第一干涉部12与壳体3形成卡扣连接，实现输入线2与壳体3之间的固定。本申请的固线扣1实现输入线与电器壳体之间的固定，不需要使用螺钉，结构简单，而且仅在壳体的外部操作能实现固定安装，简化安装过程。
进一步的，第一干弹性体121和第二弹性体131与底板10的表面之间的角度优选为90度。也可以将第二弹性体131与底板10表面之间的角度设为85度，使第二弹性体13向过线孔11的内侧倾斜，能够更好地将夹紧固线凸环211。
进一步的，底板10的第一表面102还设有转动限位部101，转动限位部101与第一干涉部12位于底板10的同一侧表面上。转动限位部101自底板10的表面凸起延伸出，在壳体3的固线通孔31的边缘设有转动限位缺口32，转动限位缺口32与固线扣1的转动限位部101配合卡接连接，如图所示，转动限位部101卡入转动限位缺口32中，实现限制固线扣1和输入线2的转动，即固线扣1无法绕固线通孔31转动。
本实施例中，第一干涉部12与第二干涉部13位于底板10的同一表面，第一干涉部12到过线孔11中心的距离大于第二干涉部13到过线孔11中心的距离。第一干涉部12在插入壳体3的固线通孔31时，会被固线通孔31向 朝向过线孔11内侧挤压变形，第一干涉部12到过线孔11中心的距离大于第二干涉部13到过线孔11中心的距离实现第一干涉部12顺利变形，挤进固线通孔31中。
为了方便固线扣1的第一干涉部12挤进固线通孔31，在第一钩体12设有第一导向斜面123。为了方便固线凸环211卡入第二干涉部13形成的空间中，在第二钩体13设有第二导向斜面133。
本实施例中的固线扣1优选采用橡胶材料一体注塑成型。橡胶是具有可逆形变的高弹性聚合物材料，具有较好的抗扭抗挤压能力，降低损坏风险。
在上述实施例中，第一干涉部12和第二干涉部13均设在底板10的第一表面上，固线扣1比较紧凑美观，占用体积较小。在另外的实施例中(图未示出)，第一干涉部12和第二干涉部13可以分别设于底板10的第一表面102和第二表面103上，当第一干涉部12插入固线通孔31时，第二干涉部12裸露于外部，能够实现固定将输入线2与壳体3的固定，第二干涉部13如果裸露于壳体3外部会导致美观度降低，而且裸露于外，容易被损坏。
如图4至6所示，本实施例的图4至6为了说明的简便，将壳体的其他部分舍弃，未予以显示，作为一种优选实施例，壳体可以为如图7所示壳体。公开了一种符合本申请较佳实施例的固线结构，包括：输入线2、壳体3和固线扣1，固线扣1为上述较佳实施例的固线扣。输入线2包括绝缘表皮21和由绝缘表皮21包覆的导线22，输入线2的绝缘表皮21设有固线凸环211，固线凸环211由输入线2经过二次注塑加工形成。输入线2自固线扣1的底 板10设有第二干涉部13的一侧表面插入过线孔11，挤压第二干涉部13，使第二干涉部13的第二弹性体131发生变形向外侧张开，固线凸环211卡入多个第二干涉部13形成的空间中且固线凸环211被限位于第二钩体132与底板10的表面之间，即固线凸环211被夹持在多个第二干涉部13围成的空间中，实现输入线2与固线扣1之间的固定。壳体3设有固线通孔31，输入线2插入固线通孔31，固线通孔31挤压第一干涉部12，使第一干涉部12的第一弹性体121变形向内压缩，固线扣1的第一干涉部12插入固线通孔31中，壳体3被限位于第一干涉部12的第一钩体121与底板10的表面之间，即第一干涉部12与壳体3形成卡扣连接，实现输入线2与壳体3之间的固定。本申请的固线结构不需要使用螺钉，结构简单，而且仅在壳体的外部操作能实现固定安装，简化安装过程。
进一步的，固线通孔31的边缘设有转动限位缺口32，底板10的表面设有转动限位部101，转动限位缺口32与固线扣1的转动限位部101配合连接。如图5所示，转动限位部101卡入转动限位缺口32中，实现转动限位，即固线扣1无法绕固线通孔31转动。
进一步的，固线凸环211的第一端2111设有防转台阶口212，防转台阶口212与第二钩体132配合卡接。使输入线2与固线扣1无法相对转动，即实现防止输入线2转动。
进一步的，固线凸环211设有防转台阶口212外的第二端2112设有导入斜面213，导入斜面213与第二钩体132的第二导向斜面133配合将固线凸 环211导入到多个第二干涉部13围成的空间中。
如图7和8所示，为本申请的一种照明装置的较佳实施例的分解图，该照明装置包括：壳体3、光源组件4、灯罩5、输入线2和固线扣1，光源组件4包括光源板41、设于光源板41的光源42以及与光源板41电连接的光源驱动43，光源组件4安装于壳体3中，灯罩5与壳体4连接并罩设光源组件4；输入线2穿固线扣1的过线孔11，固线扣1安装于壳体3的固线通孔31，以实现输入线2伸入壳体3与光源驱动43连接且输入线2固定安装于固线通孔31。另外，还包括两个端头6，两个端头6分别安装于壳体3的两端。
应当注意的是，本申请的实施例有较佳的实施性，且并非对本申请作任何形式的限制，任何熟悉该领域的技术人员可能利用上述揭示的技术内容变更或修饰为等同的有效实施例，但凡未脱离本申请技术方案的内容，依据本申请的技术实质对以上实施例所作的任何修改或等同变化及修饰，均仍属于本申请技术方案的范围内。
