具体实施方式
以下将结合附图及实施例，对实现发明目的的技术方案作详细说明。应当理解，此处所描述的具体实施例仅仅用以解释本发明，并不用于限定本发明。
参照图3及图4，图3是本发明连接装置中第一连接件一实施例的结构示意图；图4是本发明连接装置中第二连接件的结构示意图。本发明一种连接装置，其包括第一连接件100及第二连接件200，所述第一连接件100及第二连接件200均为塑胶件。所述第一连接件100包括限位部110及与所述限位部110连接的至少两弹性悬臂120，所述限位部110在两弹性悬臂120之间设有通孔130，所述弹性悬臂120上还设有卡持部。在本实施例中，该卡持部为凸出弹性悬臂120自由端的卡勾123。
所述第二连接件200包括抵顶部210及垂直于抵顶部210延伸、且可穿过所述通孔130的推拉部220，所述抵顶部210两端设有供所述弹性悬臂120穿过的定位环230。
所述第一连接件100与第二连接件200连接时，所述弹性悬臂120卡合于定位环230内，推拉部220穿入通孔130，对抵顶部210施加作用力使其抵顶于限位部110。
具体地，所述限位部110包括抵顶面111，弹性悬臂120包括固定端121及自由端122，其固定端121设置在抵顶面111上，自由端122凸伸出抵顶面111。而且两弹性悬臂120的固定端121之间的间距比自由端122之间的间距小。
所述抵顶部210为工字状，包括第一侧面211及第二侧面212。所述定位环230贯通所述抵顶部210的第一侧面211及第二侧面212，包括由抵顶部210两侧分别向外弯折延伸的侧壁231，两侧壁231的自由端相对设置，且两者之间相隔一段距离而形成开口232。
参照图5及图6，图5为第一连接件100与第二连接件200组装时的状态示意图，图6为第一连接件100与第二连接件200组装完成的状态示意图。推拉部220自弹性悬臂120间插入通孔130，并向内挤压所述弹性悬臂120的自由端122，使所述开口232发生形变，从而将弹性悬臂120套设在定位环230内；并推动所述抵顶部210或拉动所述推拉部220，使第二连接件200相对于第一连接件100沿图5中箭头A方向运动，直至抵顶部210抵顶于限位部110，即抵顶部210的第一侧面211抵顶于限位部110的抵顶面111，定位环230运动至弹性悬臂120的固定端121处时，弹性悬臂120的固定端121之间的间距比自由端122之间的间距小，弹性悬臂120弹性恢复。
请参阅图6，在拆卸所述第一连接件100与第二连接件200时，挤压所述两弹性悬臂120的自由端122使其向内靠拢；并对推拉部220施加推力，使得定位环230沿弹性悬臂120并向箭头B方向运动至弹性悬臂120的自由端。如图5所示，再将弹性悬臂120与定位环230分离，完成第一连接件100与第二连接件200的拆卸。
上述定位环230的截面形状与弹性悬臂120的截面形状适配，例如弹性悬臂120的截面形状为四边形，则定位环230的截面形状也为四边形；若弹性悬臂120的截面形状为圆形，则定位环230的截面形状也为圆形。而且开口232在弹性悬臂120穿过定位环230时产生的变形，可以使得弹性悬臂120可以更加顺利地穿过定位环230。
请参阅图7，其为本发明连接装置中第一连接件另一实施例的结构示意图，在本实施例中的第一连接件与第一实施例的第一连接件区别在于：上述卡持部为由弹性悬臂320的自由端322向内开设的卡槽323。第一连接件100与第二连接件200组装时，推拉部220自弹性悬臂320间插入通孔330，并将弹性悬臂320套设于定位环230内；并推动所述抵顶部210或拉动所述推拉部220，使第二连接件200相对于第一连接件100运动，直至抵顶部210抵顶于限位部110，定位环230运动至弹性悬臂320的固定端321处时，弹性悬臂320弹性恢复。由于本实施例中卡持部为弹性悬臂320的自由端开设的卡槽323，故该弹性悬臂320不需要挤压就可以套设在定位环230内，从而使得与本实施例配合连接的第二连接件200的定位环230不需要设置开口232。
参照图8，其为本发明背光模组组装后的剖面结构示意图。该背光模组包括第一组件1、第二组件2及连接第一组件1和第二组件2的连接装置。所述第一组件1上设有第一贯穿孔11，第二组件2的对应位置设有第二贯穿孔21。如图3及图4所示，该连接装置包括第一连接件100及第二连接件200。该第一连接件100及第二连接件200的具体结构及组装、拆卸原理可参照上面所述，在此就不再赘述。第一连接件100与第二连接件200连接成图5的状态后，穿过第一贯穿孔11及第二贯穿孔21，且第一连接件100的限位部110抵顶于第一组件1上，该限位部110的形状不限定于长方形，凡是能卡抵于第一组件1上的任何形状的限位部110，均在本发明的保护范围之内；对推拉部220施加拉力或对抵顶部210施加推力，则抵顶部210向限位部110靠近直至抵顶部210抵顶于第一组件1上，使得第一组件1卡持于所述限位部110与抵顶部210之间；此时弹性悬臂120也恢复形变，其卡持部将第二组件2卡持，在本实施例中，所述卡勾123卡持在第二组件2上；在其他实施例中，也可以是如图7所示的卡槽323卡持在第二组件2上。拆卸时，推动所述推拉部220，使定位环的侧壁231挤压所述两弹性悬臂120的自由端122使其向内靠拢，使得卡持部与第二组件2脱离，从而使得第一连接件100与第二连接件200形成图5所示的状态，再将其由第一贯穿孔11及第二贯穿孔21取出，即可完成第一组件1及第二组件2的拆卸。
本发明实施例通过第一连接件100及第二连接件200的简单结构，而且通过对推拉部220施加作用力，即可完成背光模组的第一组件1及第二组件2的组装及拆卸，不但结构简单，其组装拆卸方便，而且其拆卸时也不会损坏第一组件1及第二组件2。
以上所述仅为本发明的优选实施例，并非因此限制本发明的专利范围，凡是利用本发明说明书及附图内容所作的等效结构或流程变换，或直接或间接运用在其他相关的技术领域，均同理包括在本发明的专利保护范围内。
