在一些实施例中,如图5所示,沿套筒21的轴线,套筒21的一端设置有开口21b,该开口21b与上述第一收容腔21a连通,该开口21b用于供上述内嵌件22自开口21b插入或者脱离第一收容腔21a内。其中,内嵌件22自开口21b插入时,内嵌件22与套筒21相互配合实现对待安装部件的夹持,内嵌件22自开口21b脱离时,内嵌件22与套筒21分离,不再对待安装部件夹持。
在一些实施例中,上述限位部212环绕套筒21设置,且上述限位部212位于靠近第一收容腔21a的开口21b处。限位部212环绕设置,可增大限位部212与待安装件之间的接触面积,便于后续对待安装部件进行夹持。
在一些实施例中,上述内嵌件22设置有第二收容腔22a以及第二通孔222,第二通孔222与第二收容腔22a连通,弹性卡接件221的一端连接于第二通孔222的侧壁,在弹性卡接件221的受到朝向第二收容腔22a的作用力时,弹性卡接件221至少部分可自第二通孔222回缩至第二收容腔22a内。第二收容腔22a便于容纳回缩的弹性卡接件221。
在一些实施例中,如图4和图5所示,上述弹性卡接件221和第一通孔211的数量均为两个,两个弹性卡接件221相对设置,并且一弹性卡接件221至少部分从一第一通孔211伸出,两个弹性卡接件221从第一通孔211伸出的部分和限位部212用于共同夹持待安装部件,从而使得夹持的待安装部件更为稳定。

在一些实施例中,弹性卡接件221包括弹性形变部2211、抵接部2212和卡抓2213,弹性形变部2211的第一端连接于第二通孔222的侧壁,弹性形变部2211的第二端从第一通孔211伸出,且弹性形变部2211的第二端和抵接部2212的第一端连接,抵接部2212的第二端穿过第一通孔211,并且延伸至第一收容腔21a内,抵接部2212用于和限位部212共同夹持待安装部件,该待安装部件可为箱体01等,上述卡抓2213的第一端与抵接部2212的第二端连接,卡抓2213的第二端抵接于套筒21的内壁。其中,弹性形变部2211可在外力作用下发生形变,从而可带动抵接部2212与待安装部件抵接或者带动抵接部2212与待安装部件脱离。在上述卡抓2213的第二端抵接于套筒21的内壁时,可限制内嵌件22朝第一收容腔21a的开口21b方向移动。
在一些实施例中,如图7所示,抵接部2212的第二端插接于第一通孔211,抵接部2212位于靠近第一通孔211的第一侧壁211a,弹性形变部2211抵接于第一通孔211的第二侧壁211b,第一通孔211的第一侧壁211a和第一通孔211的第二侧壁211b相对设置。其中,部分位于第一通孔211内的抵接部2212可通过与第一侧壁211a配合,从而限制内嵌件22相对于套筒21转动。

根据本申请的一些实施例,可选地,如图6所示,上述弹性卡接件221包括弹性形变部2211和抵接部2212,弹性形变部2211的第一端与内嵌件22连接,弹性形变部2211的第二端从第一通孔211伸出,并且弹性形变部2211的第二端和抵接部2212的第一端连接,抵接部2212用于和限位部212共同夹持待安装部件。
其中,弹性形变部2211由弹性材料制作而成,弹性形变部2211可进行弹性变形,从而带动抵接部2212在第一通孔211内运动,例如:在弹性形变部2211受到朝向第一收容腔21a方向的作用力时,弹性形变部2211的第二端朝向第一收容腔21a方向运动,从而带动抵接部2212朝向第一收容腔21a方向运动,直至便于内嵌件22可从第一收容腔21a内取出,在内嵌件22插入第一收容腔21a的过程中,弹性形变部2211的第二端与第一收容腔21a的内表面接触,且弹性形变部2211的第二端受到朝向第一收容腔21a方向的作用力发生形变,直至弹性形变部2211进入第一通孔211内,弹性形变部2211恢复形变,同时,抵接部2212进入第一通孔211内,并利用抵接部2212限制内嵌件 22朝第一收容腔21a的开口21b方向运动。
根据本申请的一些实施例,可选地,上述抵接部2212的第二端穿过第一通孔211,并且延伸至第一收容腔21a内;弹性卡接件221还包括卡抓2213,卡抓2213的第一端与抵接部2212的第二端连接,卡抓2213的第二端抵接于套筒21的内壁。
弹性形变部2211在受到朝向第一收容腔21a方向的作用力时,弹性形变部2211带动抵接部2212的第二端朝第一收容腔21a方向运动,且延伸至第一收容腔21a内。上述卡抓2213的第二端抵接于套筒21的内壁,可限制内嵌件22朝第一收容腔21a的开口21b方向运动。
根据本申请的一些实施例,可选地,上述抵接部2212的第二端插接于第一通孔211,抵接部2212位于靠近第一通孔211的第一侧壁211a,弹性形变部2211抵接于第一通孔211的第二侧壁211b,第一通孔211的第一侧壁211a和第一通孔211的第二侧壁211b相对设置。
利用抵接部2212位于靠近第一通孔211的第一侧壁211a,弹性形变部2211抵接于第一通孔211的第二侧壁211b,从而将内嵌件22固定于套筒21的第一收容腔21a内,以及,限制内嵌件22朝第一收容腔21a的开口21b方向运动,减小内嵌件22的移动。可以理解的是,在一些实施例中,利用上述卡抓2213与套筒21的内壁抵接从而限制内嵌件22朝第一收容腔21a的开口21b方向运动。
根据本申请的一些实施例,可选地,内嵌件22设置有第二收容腔22a以及第二通孔222,第二通孔222与第二收容腔22a连通,弹性形变部2211的第一端连接于第二通孔222的侧壁,在弹性卡接件221受到朝向第二收容腔22a的作用力时,弹性卡接件221至少部分可自第二通孔222回缩至第二收容 腔22a内。其中,第二通孔222可便于弹性卡接件221回缩至第二收容腔22a内,第二收容腔22a可用于容纳弹性形变部2211的部分部件,且在弹性卡接件221回缩至第二收容腔22a内,抵接部2212位于第二收容腔22a内时,内嵌件22可从套筒21上取下,且可朝第一收容腔21a的开口21b方向运动。
根据本申请的一些实施例,可选地,内嵌件22设置有调节间隙22b,调节间隙22b将内嵌件22分成第一部分22c和第二部分22d,第一部分22c设置有卡口22c1,第二部分22d设置有卡接部22d1,卡接部22d1至少部分卡接于卡口22c1内,调节间隙22b由卡接部22d1和卡口22c1之间间隔预设距离形成。
需要说明的是:内嵌件22插入套筒21的第一收容腔21a内,为防止内嵌件22完全“卡死”于套筒21内,以致于难以从套筒21内取出,内嵌件22的外周面与第一收容腔21a的内壁通常间隔预设距离。因此,在内嵌件22的外周面的直径较大时,可通过减小调节间隙22b的距离以减小内嵌件22的外周面的直径。当然,也可以根据其他一些实际情况,通过增大调节间隙22b的距离以增大内嵌件22的外周面的直径,此处不作具体限定。
根据本申请的一些实施例,可选地,限位部212环绕套筒21设置,且限位部212位于靠近第一收容腔21a的开口21b处,弹性卡接件221和第一通孔211的数量均两个,两个弹性卡接件221相对设置,并且一弹性卡接件221至少部分从一第一通孔211伸出,两个弹性卡接件221从第一通孔211伸出的部分和限位部212用于共同夹持待安装部件。其中,环绕套筒21设置的限位部212可增大与待安装部件的接触面积,相对设置的两个弹性卡接件221可使得待安装部件的夹持更为稳定。
根据本申请的一些实施例,可选地,沿套筒21的轴线,套筒21的一端设 置有开口21b,开口21b与第一收容腔21a连通,开口21b用于供内嵌件22自开口21b插入或者脱离第一收容腔21a内。内嵌件22可从开口21b插入或脱离第一收容腔21a内。
在本申请实施例中,通过设置有套筒21和内嵌件22,其中,套筒21设置有第一收容腔21a与第一通孔211,第一通孔211与第一收容腔21a连通,套筒21的外周面设置有限位部212,内嵌件22收容于第一收容腔21a,内嵌件22设置有弹性卡接件221,弹性卡接件221至少部分从第一通孔211伸出,用户可利用弹性卡接件221从第一通孔211伸出的部分与限位部212共同夹持待安装部件,之后,将限位部212与外部设备连接,从而实现待安装部件与外部设备之间的连接,安装便利,效率较高,且减少连接组件20对产品的影响。
最后应说明的是:以上各实施例仅用以说明本申请的技术方案,而非对其限制;尽管参照前述各实施例对本申请进行了详细的说明,本领域的普通技术人员应当理解:其依然可以对前述各实施例所记载的技术方案进行修改,或者对其中部分或者全部技术特征进行等同替换;而这些修改或者替换,并不使相应技术方案的本质脱离本申请各实施例技术方案的范围,其均应涵盖在本申请的权利要求和说明书的范围当中。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。本申请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。
