如图2所示，本实施例的芯轴配合凸起92为板状结构。芯轴配合凸起92包括径向延伸板92a以及轴向延伸板92b。径向延伸板92a沿定位孔91的径向延伸。轴向延伸板92b沿定位孔91的轴向延伸。轴向延伸板92b通过径向延伸板92a与定位孔91的孔壁相连接。芯轴位于外壳1容纳孔4中的端部能够插入到芯轴配合凸起92的轴向延伸板92b围绕形成的空间内以完成彼此之间的插接配合。上述芯轴配合凸起92的结构能够提高自身强度，提升承载能力，另外，这样的结构也便于芯轴连接件9的整体加工制造，例如可以通过冲压或铸造的方式大批量、一体成型加工制造具有上述结构的芯轴配合凸起92的芯轴连接件9，生产效率高。
如图2所示，本实施例的安装部9b包括的每个芯轴配合凸起92的轴向延伸板92b包括朝向定位孔91的内侧表面93以及背向定位孔91的外侧表面94。芯轴配合凸起92的轴向延伸板92b与芯轴的端部插接配合后，轴向延伸板92b的内侧表面93可以与芯轴的端部的外周表面相贴合，提升芯轴配合凸起92与芯轴连接稳定性。本实施例的外壳1还包括与容纳孔4相连通且同轴设置的限位孔(图中未示出)。本实施例的限位孔为圆柱形。芯轴配合凸起92的轴向延伸板92b能够插入限位孔内，使得轴向延伸板92b的外侧表面94与限位孔的孔壁相配合。
如图4所示，本实施例的轴向延伸板92b的横截面的内侧表面93轮廓线为直线，且所有轴向延伸板92b的横截面的内侧表面93轮廓线的延长线相交形成边数大于三的多边形。优选地，上述多边形为正多边形，例如正三角形、正方形、正五边形等。优选地，本实施例的所有轴向延伸板92b的横截面的内侧表面93轮廓线的延长线相交形成正四边形。由于芯轴的端部的横截面通常大致呈正方形，因此方便与芯轴的端部进行配合。
当锁紧弹簧构件7转动时，轴向延伸板92b会相对限位孔沿限位孔的周向转动。在一个实施例中，轴向延伸板92b的横截面的外侧表面94轮廓线为圆弧，所有轴向延伸板92b的横截面的外侧表面94轮廓线的延长线形成圆形。轴向延伸板92b的外侧表面94与限位孔的孔壁相接触配 合，从而由于轴向延伸板92b受到限位孔的限制且轴向延伸板92b的外侧表面94与限位孔的孔壁在周向方向上均形成有接触区域，因此使得轴向延伸板92b转动过程中受力均衡，降低锁紧弹簧构件7在转动过程中受到额外的冲击载荷的影响，提升了锁紧弹簧构件7转动过程的平稳性。
在一个实施例中，如图1、图4所示，轴向延伸板92b的外侧表面94包括沿周向方向依次连接的第一圆柱面941、平面942以及第二圆柱面943，第一圆柱面941与第二圆柱面943同轴且与定位孔91同轴。所有的轴向延伸板92b的第一圆柱面941以及第二圆柱面943均同轴设置，从而保证所有的第一圆柱面941以及第二圆柱面943都处于同一圆柱面上。当芯轴配合凸起92的轴向延伸板92b插入限位孔内时，轴向延伸板92b的外侧表面94的第一圆柱面941和第二圆柱面943与限位孔的孔壁接触配合，轴向延伸板92b的外侧表面94的平面942与限位孔的孔壁形成有间隙。这样，轴向延伸板92b的外侧表面94与外壳1上的限位孔的孔壁的接触面积会变小，从而在保证轴向延伸板92b的外侧表面94受到限位孔的限制作用前提下，能够降低轴向延伸板92b的外侧表面94与限位孔的孔壁之间的摩擦阻力，有利于降低驱动锁紧弹簧构件7所需的转动力，避免锁紧弹簧构件7转动过程中出现顿挫情况，提升锁紧弹簧构件7转动过程的平稳性。
本发明实施例的轴向延伸板92b上背向定位孔91的外侧表面94上设置有凹槽944。具有凹槽944的轴向延伸板92b的外侧表面94与外壳1上的限位孔的孔壁的接触面积会变小，从而在保证轴向延伸板92b的外侧表面94受到限位孔的限制作用前提下，能够降低轴向延伸板92b的外侧表面94与限位孔的孔壁之间的摩擦阻力，有利于降低驱动锁紧弹簧构件7所需的转动力，避免锁紧弹簧构件7转动过程中出现顿挫情况，提升锁紧弹簧构件7转动过程的平稳性。
在一个实施例中，如图5所示，凹槽944设置在轴向延伸板92b的外侧表面94上且沿定位孔91的周向延伸。进一步地，凹槽944周向贯穿轴向延伸板92b的整个外侧表面94。优选地，多个凹槽944沿定位孔91的轴向间隔设置在轴向延伸板92b的外侧表面94上，进一步降低轴向延伸 板92b的外侧表面94与限位孔的孔壁之间的摩擦阻力。
在另一个实施例中，如图6所示，每个芯轴配合凸起92的轴向延伸板92b包括顶部以及底部。轴向延伸板92b通过底部与径向延伸板92a相连接，顶部远离径向延伸板92a。凹槽944设置在轴向延伸板92b的外侧表面94上，且从顶部沿定位孔91的轴向朝底部延伸。进一步地，凹槽944在定位孔91的周向方向上设置于轴向延伸板92b的中间位置。优选地，多个凹槽944沿定位孔91的周向间隔设置在轴向延伸板92b的外侧表面94上，进一步降低轴向延伸板92b的外侧表面94与限位孔的孔壁之间的摩擦阻力。
本实施例的两个以上的芯轴配合凸起92沿定位孔91的周向均匀设置。这样，一方面，方便加工制造安装部9b，提高生产效率；另一方面，周向均匀设置的芯轴配合凸起92中的每个芯轴配合凸起92受力更加均匀，承受的冲击载荷更均衡，有利于提升锁紧弹簧构件7转动过程的平稳性，避免锁紧弹簧构件7过早发生损伤，延长锁紧弹簧构件7的使用寿命。
本实施例的芯轴连接件9为一体成型部件，从而提高了锁紧弹簧构件7的整体强度，提升了锁紧弹簧构件7的承受冲击载荷的能力，不易发生变形、损坏，进而延长了锁紧弹簧构件7的使用寿命，保证具有本实施例的锁紧弹簧构件7的旋转隔离开关能够长期正常工作。本实施例的环形部件8和芯轴连接件9的材料均为金属材料，例如钢或铝合金等。由金属材料加工制造的环形部件8和芯轴连接件9的强度更高。本实施例一体成型的芯轴连接件9可以通过冲压或铸造的加工工艺进行制造。上述的加工工艺简单、难度低，从而简化芯轴连接件9的生产工艺，减少了生产工序，进而提高了芯轴连接件9的生产效率，降低了人力和材料成本。
本实施例的环形部件8为板状部件。本实施例的芯轴连接件9除芯轴配合凸起92之外整体上为板状部件。
本发明实施例的锁紧弹簧构件7包括相互连接的环形部件8和芯轴连接件9。芯轴连接件9具有用于与芯轴连接配合使用的定位孔91以及芯轴配合凸起92，通过芯轴配合凸起92传递转动力矩，传动过程平稳。锁紧 弹簧构件7整体结构简单，自身强度高，从而能够提升承载能力，降低额外载荷冲击造成的损伤程度，有利于延长锁紧弹簧构件7的寿命，保证旋转隔离开关长期正常地工作。
本发明还涉及一种旋转隔离开关。本实施例的旋转隔离开关包括上述的锁紧弹簧构件7。本实施例的旋转隔离开关操作省力、简便。由于锁紧弹簧构件7具有良好的承载性能，因此本实施例的旋转隔离开关能够保持长期正常工作状态，提升了旋转隔离开关的可靠性和工作稳定性。
虽然已经参考优选实施例对本发明进行了描述，但在不脱离本发明的范围的情况下，可以对其进行各种改进并且可以用等效物替换其中的部件。尤其是，只要不存在结构冲突，各个实施例中所提到的各项技术特征均可以任意方式组合起来。本发明并不局限于文中公开的特定实施例，而是包括落入权利要求的范围内的所有技术方案。
