一种旋钮帽固定组件及旋钮开关 【技术领域】
本申请涉及通信领域，具体涉及一种旋钮帽固定组件及旋钮开关。
【背景技术】
当前，旋钮帽与旋钮的旋钮转轴之间一般基于摩擦力实现固定连接。结合图1和图2所示，在旋钮11的旋钮转轴111插入旋钮帽12的轴孔121中时，所述旋钮转轴111和旋钮帽12之间设置一具有弹性结构的轴衬13，通过该轴衬13和旋钮转轴111、以及轴衬13和旋钮帽12之间的摩擦力(又称紧固力)实现旋钮帽12和旋钮转轴111之间的紧固。这种结构虽然在短期内的固定效果比较有效，但是当旋钮转轴111和旋钮帽12之间经过多次插拔后，所述轴衬13容易发生形变，例如轴衬13的外形尺寸变大等，导致轴衬13和旋钮转轴111、以及轴衬13和旋钮帽12之间的摩擦力变小，从而使得旋钮帽12容易松脱。
【发明内容】
鉴于此，本申请提供一种旋钮帽固定组件及旋钮开关，能够在多次插拔后依然使得旋钮帽受到较大的紧固力，有利于避免旋钮帽松脱。
本申请一实施例的旋钮帽固定组件，包括旋钮帽、卡环以及具有旋钮转轴的旋钮，所述旋钮转轴上设置有凹槽，所述旋钮帽和卡环均套设于旋钮转轴上，且卡环位于凹槽内并与旋钮帽紧配合。

【具体实施方式】
本申请的主要目的是：设计旋钮转轴上开设有凹槽，在旋钮帽套设于旋钮转轴上时，卡环套设于旋钮转轴上且位于凹槽内，凹槽的槽壁限制卡环移动，并且卡环与旋钮帽紧配合，以此阻挡旋钮帽朝向背离旋钮的方向移动，本申请通过凹槽与卡环这种卡合结构实现旋钮帽的紧固，即使在多次插拔后这种卡合结构的卡合也比较牢靠，依然可以使得旋钮帽受到较大的紧固力，以此有利于避免旋钮帽松脱。
下面将结合下文实施例中的附图，对本申请所提供的各个示例性的实施例的技术方案进行清楚、完整地描述。应理解，在不冲突的情况下，下述实施例及各实施例中的技术特征可以相互组合。并且，本申请全文所采用的方向性术语，例如“上”、“下”、“前”、“后”等，均是为了更好的描述各个实施例，并非用于限制本申请的保护范围。
图3是本申请一实施例的旋钮帽固定组件的结构分解示意图。如图3所示，所述旋钮帽固定组件包括旋钮31、旋钮帽32及卡环33。
结合图4所示，旋钮31又称旋钮开关，包括本体311a以及由本体311a向外延伸的旋钮转轴311，该本体311a内置有导电元件以实现电路的导通与断开，所述旋钮转轴311包括一体成型的第一转轴部311b和第二转轴部311c，其中，第一转轴部311b邻近本体311a且其外部设有外螺纹以用于与其他具有内螺纹的构件螺纹拧合，第二转轴部311c设置于旋钮31的外端，并且，沿旋钮转轴311的长度延伸方向，所述第二转轴部311c呈D型结构，所谓D型结构可以理解为：圆柱状的旋钮转轴311沿其长度延伸方向被切去一部分，切去后的旋钮转轴311 的切面为平面。同理，第一转轴部311b也可以为D型结构。
不同于现有技术，所述旋钮转轴311的端部，具体为第二转轴部311c的外端，设置有凹槽312，该凹槽312沿旋钮转轴311的轴向设置。
结合图3和图5所示，旋钮帽32的中部开设有轴孔321，沿插置轴孔321的方向(即沿旋钮帽32的厚度方向)，所述轴孔321至少包括两个轴孔区域，其中一个轴孔区域的形状与第二转轴部311c的截面形状相同，为D型，于此，当第二转轴部311c插置于轴孔321中时，旋钮帽32与第二转轴部311c紧配合；另一个轴孔区域呈环状设置，即为环形区域，其用于容置所述卡环33。
结合图3和图6所示，所述卡环33设置有缺口331，该缺口331可以使得卡环33是具有弹性的，即卡环33在受到外力时其径向尺寸可以发生改变，例如其内径可以变大。所述卡环33可以由一根金属棒环绕而成，且所述金属棒的两端在环绕后间隔设置以形成所述缺口331。其中，所述金属棒的截面形状可以为图中所示的圆形，当然该金属棒的截面形状也可以为椭圆形、以及矩形等多边形。
进一步结合图7、图8和图9所示，先将卡环33装入旋钮帽32中，卡环33与旋钮帽32过盈配合以实现相对固定，再将旋钮帽32与旋钮转轴311插合，此时旋钮帽32套设于旋钮转轴311的第二转轴部311c上并与第二转轴部311c紧配合，旋钮转轴311可以阻挡旋钮帽32相对旋钮转轴311旋转，即实现旋钮帽32的旋转止位。同时，卡环33也套设于旋钮转轴311的第二转轴部311c上，且卡环33位于所述凹槽312内。卡环33在自然状态下的内径与旋钮转轴311上的凹槽312的内径尺寸接近，可视为相等，且旋钮帽32的环形区域的直径大于卡环33在插入旋钮转轴311时的最大外径，于此，当旋钮帽32插入旋钮转轴311时，卡环33受到旋钮转轴311的挤压而往外张开，到达凹槽312区域后恢复(收缩)到自然状态，从而使旋钮帽32与旋钮转轴311相固定。
请继续参阅图9，所述凹槽312的截面和第二转轴部311c的端部均为圆弧形，且凹槽312的圆角R 2小于第二转轴部311c端部的圆角R 1，于此，将旋钮转轴311压入旋钮帽32所需的力小，而将旋钮转轴311从旋钮帽32中拔出所需的力大，从而使得旋钮帽32不易被拔出。
卡环33和凹槽312可视为一种卡合结构，凹槽312的两侧槽壁可以分别限制卡环33沿图中上下移动，而由于卡环33与旋钮帽32相对固定，因此凹槽312也限制旋钮帽32沿图中上下移动。
相比较于图1和图2所示的轴衬13，本申请借助于卡环33与凹槽312的卡合实现旋钮帽32的紧固，这种卡合结构并非借助于摩擦力，卡环33具有良好的抗形变能力，在承受负荷时不易变形，因此，即使在多次插拔后这种卡合结构的卡合也比较牢靠，本申请依然可以使得旋钮帽32受到较大的紧固力，有利于避免旋钮帽32松脱。
由上述可知，本申请实现旋钮帽32紧固的核心在于：一，卡环33与凹槽312的卡合；二，卡环33与旋钮帽32的紧配合。
对于第一种结构设计，本申请还可以设置卡环33与凹槽312的截面形状相配合，例如，卡环33的截面呈圆形，则凹槽312的截面形状可以为半圆形，于此卡环33的外表面与凹槽312的槽壁完全贴合。当然，为了进一步提高卡环33的抗形变能力，本申请可以采用抗弹性形变能力较强的材料，例如弹簧钢，来制造所述卡环33。
对于第二种结构设计，在所述卡环33与旋钮帽32配合的基础上，本申请还可以设置旋钮帽32的轴孔321内设有环形限位槽，所述卡环设置于所述限位槽内，该环形限位槽上下设置的槽壁分别夹设于卡环33的上下两侧，于此能够阻挡卡环33上下移动。进一步地，结合图8所示，旋钮帽32的环形区域的底面与卡环33设计时具有一定的过盈，当卡环33压入到旋钮转轴311的凹槽312时，卡环33受到旋钮帽32的环形区域底面的作用力，于此，旋钮帽32在轴向上不会因为卡环33、旋钮转轴311或者旋钮帽32的制造公差而上下移动。
请参阅图3、图7、图8和图10，所示旋钮帽固定组件还包括帽盖34，该帽盖34覆盖所述旋钮帽32的轴孔321。所述帽盖34的侧壁为与所述轴孔321的形状相吻合的结构，具体地，沿旋钮帽32的厚度方向，所述轴孔321包括多个轴孔区域，这些轴孔区域的直径由内向外依次增大，则所述帽盖34的侧壁可以设置多个环状件，这些环状件按照直径由大至小由外向内一圈一圈设置，每一环状件容置于相对应的轴孔区域且与该轴孔区域的孔壁面接触。另外，所述帽盖34的中部可以开设有帽孔341，用于容置并暴露第二转轴部311c的端部。
在将帽盖34盖入轴孔321后，本申请可以采用超声波热熔工艺连接帽盖34的侧壁和轴孔321的孔壁，即，帽盖34和旋钮帽32之间实现超声波热熔连接。当然，在所述帽盖34为弹性件，例如软胶塞子的应用场景中，帽盖34与所述旋钮帽32为过盈配合连接。又或者，帽盖34的侧壁设有外螺纹，旋钮帽32的内侧设置有内螺纹，帽盖34和旋钮帽32之间通过螺纹拧合方式实现拧紧。
所述帽盖34不仅用于覆盖旋钮帽32的轴孔321，以增加整个旋钮帽固定组件外观的美观性，还可以保护卡环33，以避免外力意外施加至卡环33，从而避免卡环33意外脱落。而对于采用刚性材质制得的帽盖34，在其与旋钮帽32固定连接后，帽盖34还可以阻挡卡环33脱离旋钮帽32，以此利于两者之间的固定连接。
本申请还提供一种旋钮开关，该旋钮开关包括具有上述设计的旋钮帽固定组件，因此具有与旋钮帽固定组件相同的技术效果。
应理解，以上所述仅为本申请的实施例，并非因此限制本申请的专利范围，凡是利用本申请说明书及附图内容所作的等效结构或等效流程变换，例如各实施例之间技术特征的相互结合，或直接或间接运用在其他相关的技术领域，均同理包括在本申请的专利保护范围内。
