附图说明
下面将结合附图及实施例对本发明作进一步说明，附图中：
图1是本发明一实施例的光纤连接器的分解结构示意图；
图2是图1所示光纤连接器中适配器组件和连接头组件组装后的剖视图；
图3是图1所示光纤连接器组装后的剖视图。
具体实施方式
为了对本发明的技术特征、目的和效果有更加清楚的理解，现对照附图详细说明本发明的具体实施方式。
如图1-3所示，为本发明一实施例的光纤连接器，包括适配器组件1和连接头组件2，该适配器组件1和连接头组件2相对配合可拆卸连接，连接头组件2供光缆100插接，通过适配器组件1将该光缆100与另一光缆进行对接。适配器组件1和连接头组件2通过扣合方式实现连接，拆装简单便捷。
其中，适配器组件1包括壳体11以及光纤适配器12；壳体11的相对两端贯通，光纤适配器12设置在壳体11内，可供光缆100分别从壳体11两端插接在光纤适配器12内，实现两端光缆100中的光纤进行固定对接。连接头组件2包括供光缆100穿设的第一框套21、光纤连接头23以及第二框套22，光纤连接头23设置在第一框套21内，供光缆100端部的光纤插接，第二框套22套设在第一框套21外并沿第一框套21轴向可来回移动。在适配器组件1中，壳体11具有相对的第一端和第二端，该壳体11的第一端设有至少一个具有钩部130的弹性臂13；在连接头组件2中，第一框套21朝向壳体11的一端外周设有扣槽24；第一框套21以朝向壳体11的一端插接在壳体11的第一端内，光纤连接头23插接在光纤适配器12内，弹性臂13的钩部130扣合在扣槽24内，第二框套22位于第一框套21和壳体11第一端外周，将弹性臂13的钩部130箍紧在扣槽24内，实现适配器组件1和连接头组件2的稳固连接。拆卸适配器组件1和连接头组件2时，只需将第二框套22自弹性臂13外周移开（向远离壳体11的方向拉拔），解除对弹性臂13的钩部130的箍紧，弹性臂13即可从扣槽24内脱出，使得适配器组件1和连接头组件2分离开，操作简便。
具体地，第一框套21包括连接的尾护套211和内框套212，光纤连接头23设置在内框套212内，光缆100依次穿设到尾护套211和内框套212中，而光缆100端部的光纤则裸露而插设在光纤连接头23中。尾护套211具有供光缆100通过的通孔，通孔与光缆100外周相对应设置，使得通孔与光缆100外周紧配合。光缆100可为管道式蝶形光缆、自称重式蝶形引入光缆、自称重式圆形引入光缆或光纤带式蝶形光缆等等，根据实际需要选择。光缆100插设在内框套212中的部分通常是剥除外皮的，而插设到光纤连接头23内的则是光缆100端部中的光纤。
第一框套21主要以内框套212朝向壳体11的一端与壳体11进行插接，因此，扣槽24设置在内框套212朝向壳体11的一端外周上，而尾护套211则以一端套接在内框套212远离壳体11的另一端上。尾护套211和内框套212之间的连接可采用卡扣方式实现。其中，如图1所示，在内框套211对应尾护套212的一端（远离壳体11的一端）上设有弹性扣214，尾护套211上对应设有扣孔215；通过弹性扣214扣合在扣孔215中，实现尾护套211和内框套212的连接；拆分时，下压弹性扣214使其脱离扣孔215，即可将尾护套211和内框套212分离开。
另外，如图2所示，内框套212的内部还灌封有密封胶213，将光缆100和内框套213之间进行密封。该密封胶213的设置，相较于密封圈不会因拉拔而位移，保证密封效果。当然，密封胶213也可采用密封圈代替。在内框套212中，光纤连接头23位于内框套212朝向壳体11的一端内，密封胶213则位于内框套212远离壳体11的另一端内。
第二框套22套设在内框套212外，作为外框套，可沿内框套212轴向来回移动。当第二框套22向壳体11的方向移动至内框套212与壳体11插接外周时，第二框套22将弹性臂13箍紧在扣槽24内，限制弹性臂13从扣槽24中脱出；当第二框套22向远离壳体11的方向移动至离开内框套212与壳体11插接外周时，解除了对弹性臂13的箍紧作用，弹性臂13可因弹性回复力而从扣槽24中脱出。在第二框套22和内框套212之间还设有驱动第一框套21移动后复位的弹性复位件30，通过该弹性复位件30，可驱使第二框套22在无外力拉拔时始终位于内框套212于壳体11插接的一端外周，保证第二框套22对弹性臂13的箍紧作用，且还使得第二框套22向远离壳体11的方向移动后受弹性复位件30的回复力作用，回复到内框套212插接壳体11的一端上。
在本实施例中，如图1、2所示，内框套212远离壳体11的一端外周上还设有限位槽25，第二框套22的内周凸设有限位台阶26，限位台阶26沿限位槽25长度方向可移动地配合在限位槽25内，实现第二框套22和内框套212之间的活动连接，通过限位台阶26沿限位槽25来回移动实现第二框套22在内框套212上来回移动。弹性复位件30设置在限位槽25内，且弹性复位件30的一端抵接在限位台阶26朝向尾护套211的一侧，另一端抵接在尾护套211朝向限位台阶26的一端端面。第二框套22朝向尾护套211的一端可位于尾护套211对应一端的外周，从而将弹性复位件30封闭在第二框套22和内框套212之间。该弹性复位件30可采用弹簧或其他弹性件。
进一步地，第一框套21插接在壳体11第一端内的一端外周与第一端内周之间设有密封垫圈27，解决连接头组件2和适配器组件1之间的防水问题。具体地，可在壳体11第一端内周设置容置槽（未标示），密封垫圈27容置在容置槽内；当然，容置槽也可设置在第一框套21的内框套212外周。
进一步地，连接头组件2还包括相对两端贯通的连接头安装座28，光纤连接头23通过连接头安装座28设置在第一框套21内。其中，光纤连接头23插接在连接头安装座28内，而连接头安装座28则卡设在第一框套21内。该连接头安装座28具体设置在内框套212中。
在本实施例中，如图2、3所示，壳体11的第一端设有两个相对的弹性臂13，钩部130在弹性臂13上向壳体11中心方向凸设；与弹性臂13相对应设置的扣槽24，可包括对应弹性臂13数量的槽部，以分别供弹性臂13的钩部130扣入其中，扣槽24也可为凹设在内框套212外周的环形槽。
在适配器组件1中，壳体11的外周还设有防水垫圈14，用于在适配器组件1与外部通信设备组装时，将壳体11与外部通信设备之间进行密封，以达到防水目的。此外，壳体11的外周还设有用于与外部通信设备配合安装的安装部15，防水垫圈14优选设置在安装部15的一侧或两侧。
进一步地，适配器组件1还包括盖帽13；盖帽13盖合在壳体11的与第一端相对的第二端上。在本实施例中，第二端上设有外螺纹，盖帽13对应设有内螺纹，盖帽13通过内螺纹与外螺纹配合螺接在第二端上。该盖帽13的设置，可将光纤适配器12覆盖起来，避免光纤适配器12裸露在壳体11外。
该实施例的光纤连接器组装时，先分别将适配器组件1和连接头组件2组装好，再将适配器组件1和连接头组件2相对插接。插接时，先将第二框套22向尾护套211方向拉拔，露出内框套212上的扣槽24，将适配器组件1的壳体11第二端套接在内框套212外周，以使得弹性臂13搭接在内框套212外周，直至弹性臂13上的钩部130扣合到扣槽24内，撤除对第二框套22的拉拔，第二框套22在弹性复位件30回复力作用下沿内框套212轴向向壳体11方向移动至套设在弹性臂13外周，从而将弹性臂13箍紧而限制在内框套212上。在适配器组件1和连接头组件2相对插接后，光纤连接头23的一端插接在光纤适配器12一端中，以便光纤连接头23中的光纤和插接进光纤适配器12另一端的光缆的光纤实现对接。
该实施例的光纤连接器中，光纤连接头23可为MPO型连接头、LC型连接头、SC型连接头或FC型 连接头等，光纤适配器12对应可为MPO型适配器、LC型适配器、SC型适配器或FC型适配器等，具体可 根据实际情况设置，能够将各种类型光缆连接在一起，提高该光纤连接器的灵活性。
以上所述仅为本发明的实施例，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等效流程变换，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。
