锁紧帽103的内壁还设有两个限位块132，所述两个限位块132沿所述锁紧帽103的周向间隔布置，套筒102的外壁上设有限位柱122，限位柱122位于两个限位块132之间，使得锁紧帽103相对套筒102在由两个限位块132限定的角度范围内转动；当以套筒102与光纤适配器20周向对准的方式对接光纤连接头10和光纤适配器20时，锁紧帽103相对套筒102转动到任意位置，锁紧块131均能由锁紧槽214的喇叭形开口导入到锁紧槽214的锁紧位置。即锁紧帽103相对于套筒102停留在两个限位块132限定的角度范围内的任意位置时，锁紧块131均能导入到锁紧槽214的锁紧位置。
参见图2～图4，光纤适配器20包括插座201。图6是本发明实施例提供的一种插座201的结构示意图，参见图6，插座201一端的端面上开设有用于容纳光纤连接头10的插芯101的空腔212，空腔212用于与光纤连接头10的插芯101配合对接，插座201的外壁设有至少一个锁紧槽214，锁紧槽214用于与光纤连接头10上的锁紧块131配合锁紧。
锁紧槽214的开口为喇叭形开口，当以套筒102与光纤适配器20周向对准的方式对接光纤连接头10和光纤适配器20时，锁紧帽103相对套筒102转动到任意位置，锁紧块131均能由锁紧槽214的喇叭形开口导入到锁紧槽214的锁紧位置。
在本发明实施例中，光纤套设在插芯中，在进行光纤连接时，将该光纤连接头与光纤适配器对接，从而可以将该光纤与光纤适配器的另一侧连接的光纤连接头(普通光纤连接头，如背景技术所述的螺纹连接形式的光纤连接头)的光纤对接，该光纤连接头的插芯外部设有套筒，锁紧帽可限制转动地套设在套筒之外，锁紧帽的内壁上设有锁紧块，从而与光纤适配器上的锁紧槽配合锁紧实现锁紧，在具体锁紧时，由于锁紧帽的内壁还设有与套筒外壁的限位柱匹配的两个限位块，使得锁紧帽相对套筒在两个限位块限定的角度范围内转动，当以套筒与光纤适配器周向对准的方式对接光纤连接头和光纤适配器时，锁紧帽相对套筒转动到任意位置，锁紧块均能由锁紧槽的喇叭形开口导入到锁紧槽的锁紧位置，也就是说，只要将光纤连接头的插芯和套筒与光纤适配器对接好后，锁紧帽的锁紧块就能够导入到插座的锁紧槽的锁紧位置，从而完成锁紧固定。上述光纤连接头和光纤适配器在连接和拆卸时，不需要像螺纹连接那样进行多圈转动，操作简单，耗时较少。
实现时，插座201的端面可以为圆形。喇叭形开口对应的弧度大于或等于前述角度范围，从而实现锁紧块在任意角度的插入。喇叭形开口对应的弧度是指喇叭形开口在插座201的端面上形成的圆弧的弧度。
参见图5，两个限位块132限定的角度范围可以为30-90度。也即锁紧帽103可以绕套筒102转动的角度为30-90度。相应地，光纤适配器20的锁紧槽214开口对应的弧度也可以设置为30-90度。将两个限位块132限定的角度范围设置为30-90度，一方面使得锁紧帽103可转动范围不至于过大，减小锁紧时的转动幅度，方便操作，另一方面使得锁紧帽转动范围不至于过小，保证光纤连接头10和光纤适配器20的锁紧效果。
优选地，上述两个限位块132限定的角度范围为45度。
参见图5，锁紧帽103的内壁上设有两个锁紧块131，且两个锁紧块131之间的角度为180度。相应地，光纤适配器20的外壁设有两个锁紧槽214(参见图6)，且两个锁紧槽214对称设置在光纤适配器20外壁的两侧。通过设置两个对称分布的锁紧块，可以加强光纤连接头与光纤适配器的锁紧效果。
如图1所示，套筒102的至少一部分凸出于锁紧帽103的一端之外，套筒102凸出于锁紧帽103的一端上设有开口槽121，开口槽121从套筒102的端部轴向延伸。相应地，插座201一端的端面上开设有环形的插槽211，插槽211绕设在空腔212的外周且沿插座201的轴向延伸，插槽211用于与光纤连接头10的套筒102配合对接，插槽211内设有与开口槽121相配合的定位键213(参见图6)。本发明实施例中，前述的套筒与光纤适配器周向对准可以为套筒102的开口槽121与插槽211的定位键213对准。套筒的至少一部分凸出于锁紧帽的一端之外，可以方便套筒与光纤适配器的周向对准，进而方便光纤连接头与光纤适配器的对接，对接完成后，插槽的定位键卡入套筒的开口槽中，从而实现光纤连接头与光纤适配器的周向定位。
图7是本发明实施例提供地一种套筒的结构示意图，参见图7，锁紧帽103的开口槽121的开口可以呈喇叭形，从而便于光纤连接头与光纤适配器的对接，喇叭形开口的角度α可以为10-30度。
在本发明实施例中，锁紧槽214包括横向锁紧部(对应前述锁紧位置)和214A竖向滑槽部214B(对应前述锁紧槽214的开口)，横向锁紧部214A沿插座201的周向设置，竖向滑槽部214B沿插座201的轴向设置，横向锁紧部214A和竖向滑槽部214B相互连通。其中，竖向滑槽部214B的开口呈喇叭形，即 前述喇叭形开口。锁紧块131通过竖向滑槽部214B滑入后，进入横向锁紧部214A，通过转动锁紧帽103将锁紧块131转动到横向锁紧部214A的锁紧位置(横向锁紧部214A中远离竖向滑槽部214B的位置)。
套筒102为圆柱形筒状物。当然，图7所示也仅为举例，套筒102还可以是其他筒状物，例如椭圆柱形筒状物。
如图7所示，套筒102的一端设有外凸缘123，外凸缘123的外壁上设有限位柱122，限位柱122包括但不限于圆柱形；套筒102的另一端设有前述开口槽121。当沿着套筒102的轴向从套筒102设有开口槽121的一端看去，套筒102为C型。另外，前述开口槽121轴向延伸至接近外凸缘123的位置，一方面通过设置足够长的开口槽121，保证与光纤适配器充分对接，另一方面不让开口槽121贯穿整个套筒102，使套筒102的底部能够对插芯101起到限位作用。
再次参见图2～图4，光纤连接头10还可以包括连接头防尘帽104，连接头防尘帽104用于在光纤连接头10未插入光纤适配器20时对其进行保护，起到防水防尘的作用。连接头防尘帽104的外壁设置有与锁紧块131相配合的锁紧槽，从而实现与光纤连接头10的对接。其中，连接头防尘帽104的锁紧槽可以与光纤适配器20的锁紧槽结构相同。

插芯101的后端(与前端相对的另一端)设有外螺纹，插芯101设有外螺纹的一端穿过套筒102的底部，使得插芯101设有外螺纹的后端与连接轴106设有内螺纹的前端连接。插芯101设有陶瓷插芯芯针的前端在光纤连接头10与光纤适配器20连接时，插入空腔212中。
实现时，连接轴106可以为外壁设有台阶的圆管结构，连接轴106的前端设有内螺纹，连接轴106与插芯101通过螺纹连接。
实现时，尾部组件105可以包括带胶热缩套管151、压接环152和尾护套153，压接环152套设在连接轴106的另一端(后端，与前端相对的另一端)上，且压接环152用于将光缆100的加强件压紧在连接轴106上，带胶热缩套管151的一端包裹在所述光缆100上，带胶热缩套管151的另一端包裹在连接轴的另一端及压接环152上，尾护套153套设在连接轴106和带胶热缩套管151上，且尾护套153的一端与锁紧帽103的另一端抵靠。
在该实现方式中，压接环152通过机械压接的方式将光缆的加强件(如芳纶)压接固定到连接轴106上。
在该实现方式中，带胶热缩套管151通过热缩的方式紧密粘接在连接轴106及光缆100上，保证尾部组件105的密封和紧固效果。
其中，尾护套153可以包括一圆柱管和一圆锥管，圆柱管和圆锥管的一端相连，圆柱管的另一端套设在连接轴106上，圆锥管的另一端套设在带胶热缩套管151上。
实现时，连接轴106的另一端可以设置至少两级台阶，末端为第一台阶，靠近第一台阶的为第二台阶。压接环152的另一端与连接轴106的第一台阶连接，具体可以为压接环152的另一端套设在第一台阶上，连接方式包括但不限于螺纹连接、卡接等。尾护套153套设在连接轴106的第二台阶上。
进一步地，连接头防尘帽104的第一绳带141的另一个连接圈141A可以套设在第二台阶上。为了防止第一绳带141滑动，可以在第二台阶上设置卡环161，从而对第一绳带141进行定位。
图8是本发明实施例提供的一种锁紧帽的结构示意图，参见图8，锁紧帽 103可以由多段直径不同的圆管结构组成，例如图8示出锁紧帽103可以由大直径圆管和小直径圆管两段组成，大直径圆管套设在套筒102上，小直径圆管套设在连接轴106上
如图8所示，限位块132的形状为棱台体，锁紧块131的形状为圆柱体。当然本发明实施例中锁紧块131和限位块132的形状不限如此，例如还可以是长方体、圆台体等形状。
其中，锁紧帽103的前端(与光纤适配器20连接的一端)设有箭头对准标识133，用以指示光纤连接器的连接和锁紧，相应地，光纤适配器20上设有标识连接和锁紧状态的指示标识215(参见图6)，该指示标识215包括但不限于文字(例如0和1，1标识连接，0标识锁紧)、符号、箭头等。如图6所示，本实施例采用0、1及设置在0和1之间的双向箭头(表示转动范围)作为上述指示标识215。
进一步地，锁紧帽103的外壁设有沿锁紧帽103轴向延伸的第一沟槽，这种沟槽设计能够增加锁紧帽103转动时外壁的摩擦力，从而方便锁紧帽103的转动。锁紧帽103上设有削平平面134，削平平面134内设置有垂直于锁紧帽103轴线的第二沟槽，通过设置第二沟槽以增加插拔光纤连接头时的操作手感。
优选地，削平平面134设置在锁紧帽103的后端(靠近尾管的一端)。且该锁紧帽103包括对称设置的两个削平平面134。
再次参见图2～图4，光纤连接头10还可以包括弹性件107，弹性件107设置在连接轴106和锁紧帽103之间，弹性件107的一端抵靠在连接轴106与插芯101连接的一端的轴肩上，弹性件107的另一端抵靠在锁紧帽103内腔的轴肩上，锁紧帽103的内腔的轴肩位于锁紧帽103靠近尾部组件105的一端。该锁紧帽103可以在轴向上沿连接轴106受限制地小距离滑动，弹性件107用于向锁紧帽103提供沿远离插芯101方向的弹力，从而起到连接防松的作用。
其中，弹性件107包括但不限于弹簧。
再次参见图2～图4，光纤连接头10还可以包括若干密封圈108，若干密封圈108中的一个密封圈108设置在连接轴106和锁紧帽103之间，若干密封圈108中的另一个密封圈108与锁紧帽103配套使用，作用在连接头防尘帽104与锁紧帽103之间，或者作用在光纤适配器20与锁紧帽103之间，通过设置密封圈108实现上述位置的密封效果。当密封圈108作用在光纤适配器20与锁紧帽103之间时，可以使得该光纤连接器达到IP68密封效果。
