具体实施方式
为使本发明实施例的目的、技术方案和优点更加清楚，下面将结合本发明实施例中的附图，对本发明实施例中的技术方案进行清楚、完整地描述，显然，所描述的实施例是本发明的一部分实施例，而不是全部的实施例。基于本发明中的实施例，本领域普通技术人员在没有做出创造性劳动的前提下所获得的所有其他实施例，都属于本发明保护的范围。
本发明实施例提供了一种光电复合连接器及适配器，其能解决相关技术中两次铺设线路，限制了末梢终端布局的密度，影响了覆盖范围的问题。
参见图1至图3所示，本发明实施例提供了一种光电复合连接器100，其可以包括：本体1，所述本体1内具有前后贯通的空腔11，所述空腔11内安装有插芯2，其中插芯2可供光纤73插入，插芯2可以部分或者全部收容于空腔11内，可以认为插芯2位于所述本体1的内侧，空腔11向前贯穿所述本体1的前端面，向后贯穿所述本体1的后端面，使得光纤73可以从本体1的后方插入；所述本体1内还具有至少两个端子槽12，两个所述端子槽12位于所述空腔11的同一侧，本实施例中，两个端子槽12优选设于本体1的底部，也即位于空腔11的下方，当然，也可以将两个端子槽12设置于本体1的顶部或者左侧、右侧等，根据使用需求或者习惯来设置；且两个所述端子槽12之间设有隔离壁13，使得隔离壁13将两个端子槽12隔开；所述本体1的外表面还可以设有开口14，所述开口14与所述端子槽12位于所述空腔11的同一侧，本实施例中，以开口14设于所述本体1 的底面为例，当然在其他实施例中，也可以根据端子槽12的位置来对应设置开口14的位置，比如设置于顶面或者左右侧面；且所述开口14与所述端子槽12连通，所述开口14贯穿所述本体1的前端面，其中，端子槽12可以贯穿本体1的前端面也可以不贯穿，由于端子槽12距离本体1的底面有一定的距离，也即开口14在本体1的厚度方向具有一定的深度，开口14贯穿本体1的前端面，也就会在前端面形成缺口，该缺口可供与光电复合连接器100对接的适配器200的导电元件2081插入，能够对导电元件2081起到引导的作用；以及至少两个导电端子4，分别对应收容于所述端子槽12内，导电端子4一般对称设置于本体1内，且所述导电端子4显露于所述开口14，使得适配器200的导电元件2081可以进入开口14，在开口14处于导电端子4实现电连接。
本实施例中，由于在本体1内设置了插芯2和端子槽12，光纤73可以插设于插芯2中，导电端子4可以收容于端子槽12内，通过一个连接器即可实现光传输与电传输，解决了需要分别设置光连接器和电连接器才能完成光和电的连接和传输所导致的操作复杂、且设备体积较大的问题。
并且，由于导电端子4收容于本体1内的端子槽12中，且导电端子4不凸伸出于本体1的前端面，导电端子4不会裸露在外，能够有效避免触电风险和短路风险。本发明实施例中的光电复合连接器100在连接线缆7后，线缆7可以穿过本体1内部，并收容在本体1内，利用了主体20211的内部空间，从而也就无需为容置线缆7而在光电复合连接器100上设置单独容纳线缆7的空间，也就无需改变光电复合连接器100的外形尺寸，光电复合连接器100的体积小，且线缆7在连接器内是穿孔结构，连接器强度高。
参见图5所示，一般本体1为塑料材质，例如，本体1可以为聚对苯二甲酸四次甲基酯(Polybutylene terephthalate，PBT)材质，隔离壁13可以起到隔离绝缘的作用。进一步地，本发明实施例提供的光电复合连接器100集成了光纤73连接器插头功能和电连接器插头功能，在使用时，该光电复合连接器100后端接入的线缆7可以是光电混合缆，即既包括光纤73也包括电缆，线缆7也可以是包括光缆不包括电缆；根据实际使用需求来设置光电复合连接器100后端的线缆7。现对本申请中的轴向方向和径向反向进行定义，轴向方向：可以理解为连接器的轴向方向， 等同于光纤73和插芯2的延伸方向，即光纤73的尾部延伸至光纤73的前端再继续延伸至插芯2前端的方向，也即本体1和插芯2的轴线方向。径向方向：垂直于轴向方向。进一步，端子槽12也可以向前贯穿本体1的前端面，并且在端子槽12与开口14的前端可以设置呈喇叭状的导向口。
在一些可选的实施例中，所述光电复合连接器100还可以包括夹持体31和连接件32，其中夹持体31和连接件32均收容于所述空腔11内，插芯2、夹持体31与连接件32可以依次沿轴向连接，线缆7中的光纤73可以从连接件32的后端依次穿过连接件32、夹持体31进入插芯2中。插芯2位于本体1的空腔11内，并从本体1的前端伸出，可以不与本体1的内壁接触，在本体1的空腔11内，插芯2的后端与夹持体31的前端连接，夹持体31的后部通过弹簧33与连接件32的前端接触。
进一步，关于插芯2的后端与夹持体31的前端的连接方式，可选的，该插芯2的后端和夹持体31的前端可以分别从本体1的空腔11的两端插入空腔11内，可选的，插芯2也可以在与夹持体31连接后再插入到本体1的空腔11内。当然，也可以在所述插芯2的后端与所述夹持体31的前端连接好后，在其外部套设该本体1。当然还可以通过其他方式将插芯2和夹持体31设置在该本体1内，此处不做限定。另外，插芯2与夹持体31连接的方式有很多种，这里不做限定，例如，可以是铆接，例如，夹持体31的前端有收容腔，插芯2的后端可以插入收容腔，并且，夹持体31的内壁设有凸包，夹持体31的内壁上的凸包对插芯2起到阻挡作用，能够避免插芯2全部插入到该夹持体31的空腔11内。
进一步，关于夹持体31的后端通过弹簧33与连接件32的前端接触的方式，例如，夹持体31的后端和连接件32的前端均设置有阻挡件，阻挡件用于在弹簧33受力时防止弹簧33从夹持体31和连接件32之间脱离。弹簧33能够经由夹持体31为插芯2提供一定弹力，从而保证插芯2随光电复合连接器100插入适配器200后，插芯2的端面与从适配器200的另一端插入的另外一个插芯2的端面更好地贴合。本体1的内壁与夹持体31的外壁以及连接件32的外壁接触以稳定所述夹持体31和所述连接件32。
优选的，所述光电复合连接器100还可以包括管5，管5的前端与连接件32的后端连接，或者从连接件32的后端插入连接件32内，管5的内腔用于线缆7中 光纤73的回退，即线缆7中的光纤73还贯穿所述管5，所述管5位于尾套6内部，即管5外侧套设有尾套6，从而对管5起到保护作用，连接件32的前端位于本体1内，连接件32的后端可以位于尾套6内。
进一步，所述尾套6可以包围所述连接件32、所述管5和一部分线缆7，所述尾套6的前端与所述本体1的后端贴合，贴合的直观视觉效果就是本体1基本与尾套6连为一体。可选的，所述尾套6可以采用一体注塑，可选的，尾套6采用低温注塑材料，低温注塑材料为在注塑时流动性较强的材料，比如PE，由于流动性较强，因此注塑过程中不需要外加太大压力，能够避免该低温注塑材料冲击到光纤73，从而避免光纤73变形受损。这种方式可以使尾套6和线缆7的保护套75紧密贴合，增加了尾套6对线缆7保护的严密性。可选的，尾套6也可以不通过注塑形成，例如，将两半相耦合的壳体夹在连接件32、所述管5和一部分线缆7之外，从而形成对连接件32、所述管5和一部分线缆7进行包围的尾套6。这两半相耦合的壳体之间可以通过卡扣和卡槽扣紧，或者通过螺钉和螺纹拧紧，或者通过其他方式进行结合，此处不做限定。
进一步，参见图16所示，本实施例中的线缆7的外层为缆皮71，缆皮71内包裹了电线72和光纤73，由内向外看，光纤73的外面一次设置了紧包74、保护套75，可选的，保护套75可以为芳纶，本实施例中，可以将包裹了紧包74的光纤73穿入管5内，而管5会插入到保护套75内，因此，电线72不穿过管5，管5具有一定的硬度，其可以弯曲但是无法弯折为较大角度，因此，可以避免光纤73在该管5内弯折、折断，从而为光纤73的回退提供空间，例如，管5可以为聚对苯二甲酸四次甲基酯(Polybutylene terephthalate，PBT)材质。其中，光纤73的回退可以理解为，当适配器200的两端都插入了光电复合连接器100后，两个光电复合连接器100的插芯2(比如陶瓷插芯2)之间会产生相互作用力，使得两个光电复合连接器100的插芯2向彼此远离的方向移动，这就会连带两个光电复合连接器100内的光纤73往远离彼此的方向移动，即光纤73回退。由于本申请提供了管5，因此能够提供一定的空间供光纤73在里面弯曲(小幅度)，因此可以实现光线回退。可以理解，假若没有管5，光纤73外面依次被紧包74、保护套75、缆皮71包裹，那么，相当于对光纤73进行了固定，光纤73无法回退，一旦因无法回退导致光纤 73受力较大，就可能导致光纤73折断。本实施例中，线缆7中包含两根电线72，每根电线72对应与一个导电端子4电连接(参见图17)，两根电线72分别位于光纤73的相对两侧，使得电线72隔离性好，安全可靠。
本实施例中，光纤73在贯穿连接件32和夹持体31时，光纤73的外面有一层紧包74，而在贯穿插芯2时光纤73外面可以不设置紧包74。
优选的，管5的前端可以与连接件32的后端连接，比如通过卡扣连接、胶水连接等；在又一种方案中，管5的前端可以从所述连接件32的后端面插入所述连接件32内。
进一步，线缆7中的电线72和所述导电端子4的连接，该连接方式可以采用焊接、卡接等方式，优选的，电线72和导电端子4采用焊接的方式。
进一步，线缆7的保护套75穿入连接件32的后端中，保护套75的固定方式可以通过卡扣连接、胶水连接等方式固定，从而固定线缆7，保护套75可以承受一定的拉力，能够对连接件32与管5的连接起到稳定的作用，也能够对线缆7起到稳定的作用。管5的长度可以根据实际需要进行设置，此处不做限定。
在一些实施例中，参见图12所示，导电端子4可以与端子槽12耦合，从而将导电端子4固定在本体1内，其中，所述导电端子4可以具有垂直于所述本体1的轴向方向的定位面41，所述本体1具有凸伸进入所述端子槽12的凸出15，所述凸出15与所述定位面41配合，也即凸出15可以与定位面41贴合，以限制导电端子4的位置，阻止导电端子4在轴向方向移动，当然，在其他实施例中，导电端子4也可以通过点胶的方式与本体1固定，这里不做具体限定。
在一些可选的实施例中，参见图15和18所示，所述本体1还可以具有插口16，所述插口16自所述本体1的前端面向后凹陷形成，也即向后延伸有一定的深度，且所述插口16位于相邻两个所述端子槽12之间，所述导电端子4的侧面显露于所述插口16，也即插口16使得两侧的端子槽12互相贯通，该插口16可供适配器200的导电元件2081插入，以实现与导电端子4的电性连接，比如适配器200的导电元件2081可以为片状的，便于从插口16插入与导电端子4接触。
进一步，本实施例中，参见图8至图11所示，导电端子4可以具有第一接触面42、第二接触面43以及第三接触面44，第三接触面44垂直于第一接触面42且 垂直于第二接触面43，第三接触面44可以显露于所述插口16，其中，当适配器200的导电元件2081从本体1的下方插入开口14时，第一接触面42可以与适配器200的导电元件2081接触，第一接触面42可以完全收容在本体1的端子槽12内；当适配器200的导电元件2081从所述插口16插入时，第三接触面44可以与适配器200的导电元件2081接触；而第二接触面43可以位于第一接触面42的后方，第二接触面43可以用于与电线72连接。第二接触面43可以完全收容在端子槽12内，或者凸伸出本体1，当第二接触面43凸伸出本体1时，导电端子4凸伸出来的一部分会嵌入尾套6中，使得导电端子4不会裸露在外。本实施例中，第一接触面42和第三接触面44可以保证导电接触面积大，导电能力强。
在一些实施例中，参见图4所示，每个所述端子槽12均对应设有所述开口14，相邻两个所述开口14之间通过通槽17连通，也就是说，在相邻两个开口14之间增设了通槽17，使得两个开口14连通，其中通槽17内填充空气，由于本体1一般为塑料材质，其介电系数大于空气的介电系数，而介电系数越小有利于维持导电端子4之间的阻抗稳定性，因此，本实施例中，通过增设通槽17可以维持导电端子4的阻抗稳定性。
进一步，参见图13和14所示，所述光电复合连接器100还可以包括第一防尘帽8，所述第一防尘帽8包括：套筒81，所述套筒81插设于所述插芯2外，以对插芯2进行防尘；以及至少两个悬臂82，当第一防尘帽8安装于本体1上时，所述悬臂82对应盖合于所述开口14，使得第一防尘帽8将本体1的前端封闭，且相邻两个悬臂82通过连接部83连接，所述连接部83位于所述通槽17内。本实施例中，通过设置连接部83连接两个悬臂82，可以增强悬臂82的强度，同时充分利用通槽17。且第一防尘帽8可以避免灰尘、水等外界物质与插芯2和导电端子4接触。
在一些实施例中，参见图6至7所示，本体1的相对两侧可以设有卡扣槽18，连接件32的相对两侧可以设有卡扣部321，卡扣部321可以从本体1的内壁卡到卡扣槽18中，从而将连接件32固定在本体1上。本体1的表面还可以设有锁紧槽19，所述锁紧槽19用于与适配器200上的锁紧件2021配合锁紧，以对光电复合连接器100和适配器200进行固定。
进一步，本申请实施例中，要保证光电复合连接器100能够插入该适配器200且与该适配器200有较好的连接，尤其需要保证光电复合连接器100中的插芯2能够插入到适配器200中相应的插槽中，以及适配器200中的电组件208与本体1内的导电端子4连接，就需要该光电复合连接器100的外表面轮廓和该适配器200的内表面的轮廓进行设计，使得该光电复合连接器100在接入该适配器200时，以正确的插入角度进行插入，即进行引导(或者导向)设计；在一种方案中，所述本体1靠近所述光电复合连接器100插接端的端面为非中心对称架构，即所述本体1的外形轮廓为异形，只能从一个方向插入适配器200的外壳201中，在所述本体1插入所述外壳201的插接腔2011后，也不能旋转，只能在轴向方向运动。
参见图20至22所示，本发明实施例还提供了一种适配器200，用于与上述的光电复合连接器100对接，其可以包括：外壳201，所述外壳201具有插接腔2011，其中，插接腔2011用于供光电复合连接器100插接进入；且所述外壳201上安装有锁紧组件202，所述锁紧组件202包括锁紧件2021和推杆2022，所述推杆2022具有异型槽2023，所述锁紧件2021插设于所述异型槽2023内，且当沿轴向方向推动所述推杆2022时，所述推杆2022可驱动所述锁紧件2021沿径向方向移动。本实施例中，当光电复合连接器100插入外壳201的插接腔2011后，锁紧件2021可以进入光电复合连接器100的锁紧槽19中，使得适配器200与光电复合连接器100锁紧，光电复合连接器100不能脱离适配器200，当通过推杆2022将锁紧件2021抬起后，锁紧件2021从锁紧槽19中脱离，使得光电复合连接器100与适配器200解锁。并且，通过异型槽2023的设计，将轴向方向的运动转化为径向方向，不需要增加其它机械结构部件来进行转化，结构简单易操作。
优选的，参见图29所示，所述异型槽2023可以包括间隔设置的第四槽体20231和第五槽体20232，所述第四槽体20231和所述第五槽体20232的位置高度不同，也即一高一低，其中，以第四槽体20231低于第五槽体20232为例，当锁紧件2021位于第四槽体20231内时，光电复合连接器100与适配器200可以锁紧，当锁紧件2021移动至第五槽体20232内时，第五槽体20232将锁紧件2021抬高，使得锁紧件2021脱离锁紧槽19，实现解锁，且所述第四槽体20231与所述第五槽体20232通过第一斜面20233连接，第一斜面20233相对于轴向方向倾斜设置， 所述第一斜面20233使得推杆2022的轴向力转换为径向分离，进而驱动锁紧件2021沿径向方向运动。当然，在其他实施例中，所述异型槽2023也可以直接为一个倾斜的槽体，使得推杆2022在水平移动的同时，一步步将锁紧件2021抬高，驱动锁紧件2021脱离锁紧槽19。
在一些可选的实施例中，参见图24、28所示，所述外壳201可以具有第一凹槽2012，其中，第一凹槽2012优选位于外壳201的顶面，所述第一凹槽2012可以包括第一槽体20121以及连通所述第一槽体20121的第二槽体20122，所述第二槽体20122朝向远离所述第一槽体20121的方向凹陷形成；所述锁紧件2021可以包括主体20211以及设于所述主体20211一侧的凸块20212，其中，凸块20212设置于主体20211的侧面，可以为前、后、左或者右方向，所述主体20211收容于所述第一槽体20121内，且所述凸块20212收容于所述第二槽体20122。通过设置凸块20212与第二槽体20122配合，使得锁紧件2021在装配到第一凹槽2012内时，能够将装配方向限制为一个方向，并且限制锁紧件2021的径向方向运动。
进一步，所述第一凹槽2012还可以包括第三槽体20123，所述第三槽体20123朝向远离所述第一槽体20121的方向凹陷形成，且所述第三槽体20123与所述第二槽体20122间隔设置，其中，第三槽体20123可以为圆柱形或者方形，本实施例优选为圆柱形；所述主体20211上还可以设有导向凸起20213，所述导向凸起20213对应插设于所述第三槽体20123内，其中，导向凸起20213的形状与第三槽体20123的形状匹配，导向凸起20213的设置可以使得锁紧件2021能够在径向方向平行运动而不翻转。
在一些可选的实施例中，参见图23至24、30至32所示，所述外壳201还可以具有插孔2013；所述锁紧件2021可以包括：主体20211，所述主体20211具有锁紧块20214，其中，锁紧块20214可以插入光电复合连接器100的锁紧槽19中进行锁紧；以及穿设于所述主体20211上的升降轴20215，所述升降轴20215插设于所述插孔2013中且所述升降轴20215插设于所述异型槽2023内，异型槽2023通过抬升升降轴20215来实现锁紧块20214与锁紧槽19的解锁操作；也即，本实施例中，锁紧件2021优选为分体设置，主体20211和升降轴20215是分体的，然后组装在一起形成锁紧件2021，当然，在其他实施例中，主体20211和升降轴20215 也可以做成一体的。本实施例中，升降轴20215同时插设于异型槽2023和插孔2013内，升降轴20215可以限制推杆2022在轴向方向的运动距离。
参见图33至34、37和38所示，本发明实施例还提供了另一种适配器200，用于与上述的光电复合连接器100对接，其可以包括：外壳201，所述外壳201具有插接腔2011和插孔2013，且所述外壳201上安装有锁紧组件202，所述锁紧组件202包括锁紧件2021和推杆2022，所述锁紧件2021包括转动杆20216和连接所述转动杆20216的锁紧杆20217，所述转动杆20216插设于所述插孔2013，且所述转动杆20216的轴线与所述插孔2013的轴线之间具有夹角，也即转动杆20216相对于插孔2013倾斜设置；所述推杆2022具有解锁槽2024，当沿轴向方向向一侧(可以为向前)推动所述推杆2022时，所述锁紧杆20217翘起并进入所述解锁槽2024。本实施例中，由于转动杆20216相对于插孔2013倾斜设置，转动杆20216的中轴线与插孔2013的中轴线不重合，当转动杆20216插入插孔2013时，转动杆20216会产生变形，该变形会产生一个作用力，该作用力的一个分量沿着径向方向，从而驱动锁紧杆20217绕插孔2013的中轴线旋转运动，也即在转动杆20216插入插孔2013后，锁紧杆20217能够自动翘起，不需要推杆2022来推动，即可实现锁紧杆20217与锁紧槽19的解锁，同时，推杆2022上设置的解锁槽2024提供了锁紧杆20217的容纳空间。
进一步，参见图36所示，所述推杆2022于所述解锁槽2024的一侧可以设有按压部2025，当沿轴向方向向另一侧(可以为向后)推动所述推杆2022时，所述按压部2025压迫所述锁紧杆20217，使所述锁紧杆20217向远离所述解锁槽2024的方向移动，也即，在按压部2025的压迫下，锁紧杆20217下移，并可进入锁紧槽19与光电复合连接器100锁紧，不能朝脱离适配器200的方向移动。在非锁紧状态，锁紧杆20217至少一部分收容于解锁槽2024中。
在一些可选的实施例中，参见图35所示，所述锁紧杆20217可以包括第一杆202171以及连接所述第一杆202171的相对两侧的两个第二杆202172，也即第一杆202171的每一端连接一个第二杆202172，使第一杆202171与第二杆202172围成一个框，其中，第一杆202171可以与第二杆202172垂直，也可以与第二杆202172之间的夹角为钝角或者锐角，每一所述第二杆202172远离所述第一杆202171的 一端均连接有所述转动杆20216，所述第一杆202171的中轴线与所述第二杆202172的中轴线形成第一平面，所述转动杆20216相对于所述第一平面倾斜设置，也即转动杆20216的中轴线与第一平面成一定角度，转动杆20216的中轴线不位于第一平面上，也可以理解为当第一杆202171的中轴线垂直于轴向方向时，转动杆20216的中轴线不垂直于轴向方向；并且两端的转动杆20216的两个中轴线不平行，成一定角度。在其他实施例中，锁紧杆20217也可以为一个整体的弧形杆，使得锁紧杆20217可以从外壳201的左侧延伸至右侧，且锁紧杆20217的两端分别连接一个转动杆20216，每个转动杆20216对应插设于插孔2013中。
在一些实施例中，参见图39、40所示，本发明实施例又提供了一种适配器200，用于与上述的光电复合连接器100对接，其可以包括：外壳201，所述外壳201具有插接腔2011和插孔2013，插孔2013可以为一个、两个或者两个以上，且所述外壳201上安装有锁紧组件202，所述锁紧组件202包括锁紧件2021和推杆2022，所述锁紧件2021包括转动杆20216和连接所述转动杆20216的锁紧杆20217，所述转动杆20216插设于所述插孔2013；所述推杆2022具有解锁槽2024，当沿轴向方向推动所述推杆2022时，所述推杆2022驱动所述锁紧杆20217沿径向方向移动，也即，转动杆20216插设于插孔2013中，锁紧杆20217可以绕插孔2013的轴线转动，当沿轴向方向推动推杆2022时，推杆2022可以推动锁紧杆20217绕插孔2013的轴线转动，也即沿径向方向移动，使锁紧杆20217脱离光电复合连接器100的锁紧槽19，实现解锁。
优选的，参见图41、43和44所示，所述锁紧杆20217可以包括位于所述解锁槽2024内的第一杆202171以及连接所述第一杆202171的相对两侧的两个第二杆202172，每一所述第二杆202172远离所述第一杆202171的一端均连接有所述转动杆20216，其中，第一杆202171的中轴线与第二杆202172的中轴线形成一第二平面，转动杆20216的中轴线可以与第二平面共面，也可以相对于第二平面倾斜设置；所述外壳201于所述插孔2013处可以设有夹持部2018，所述夹持部2018夹持于所述第二杆202172的相对两侧。本实施例中，通过设置固定的夹持部2018，使得第二杆202172固定在夹持部2018处，不能绕插孔2013的轴线转动，由于第二杆202172具有一定的弹性，当推杆2022推动第一杆202171上移时，第二杆 202172远离夹持部2018的一端可以上翘，使得第一杆202171脱离锁紧槽19。
本实施例中，参见图42所示，解锁槽2024内设有第二斜面20241，第二斜面20241相对于轴向方向倾斜设置，第二斜面20241可以使得推杆2022的轴向力转换为径向分力，从而驱动第一杆202171沿径向方向运动。
可选的，在示例中，两个第二杆202172以及两个转动杆20216均为两端对称结构，当然在其他实施例中，也可以根据实际情况，将第二杆202172或者转动杆20216设置为非对称结构。进一步，外壳201可以具有第一凹槽2012，第一杆202171可以收容于第一凹槽2012内。
参见图32、38和43所示，进一步，上述任一实施例提供的适配器200中，所述外壳201可以设有第二凹槽2014，所述推杆2022对应所述第二凹槽2014设有第三凹槽2026，所述第三凹槽2026的轴线与所述第二凹槽2014的轴线共线，且所述第三凹槽2026与所述第二凹槽2014内收容有弹性件203。弹性件203位于第三凹槽2026与第二凹槽2014内，在光电复合连接器100与适配器200解锁的过程中，推杆2022相对于外壳201移动的过程中会压缩弹性件203，解锁后，通过弹性件203的弹性抵持力使得推杆2022弹回原位。
参见图23至24所示，进一步，上述任一实施例提供的适配器200中，所述推杆2022可以设有导槽2027，所述外壳201对应所述导槽2027设有导轨2015，所述导轨2015插设于所述导槽2027，使得推杆2022在移动的过程中可以沿着导轨2015运动，在示例中，推杆2022的移动方向为轴向方向。
优选的，需要说明的是插孔2013的中轴线垂直于轴向方向，在示例中插孔2013为两侧对称结构，即外壳201左右两侧壁都有插孔2013，且两个插孔2013对称。
进一步，适配器200还可以包括蘑菇头204，蘑菇头204用于插入到集成电路板以稳固适配器200。
在一些可选的实施例中，参见图21至22所示，适配器200还可以包括安装于外壳201内部的卡扣组件205，卡扣组件205可以包括扣持体2051和筒体2052，扣持体2051用于固定与上述光电复合连接器100对接的连接器，该连接器可以是SC标准，或者LC标准，或者其它标准的连接器，本申请对此不作具体限定，筒体2052一般为陶瓷材料，如氧化锆(ZrO2)，用于适配器200两侧的两个连接器的 插芯2(比如陶瓷插芯2)对接。
在一些实施例中，适配器200还可以包括第二防尘帽206和第三防尘帽207，当适配器200上还未装连接器时，第二防尘帽206和第三防尘帽207可以分别插设于适配器200的两端口。
进一步，参见图25至27所示，适配器200还可以包括电组件208，其中，电组件208至少包括两个导电元件2081和一个绝缘体2082，所述绝缘体2082设置在两个导电元件2081之间，可选的，所述绝缘体2082可以通过将两个导电元件2081模内注塑的方式来实现固定，防止所述绝缘体2082和两个导电元件2081相对移动。所述绝缘体2082上有固定孔20821，所述固定孔20821和所述外壳201上的柱体2016配合，实现电组件208的固定。另外，导电元件2081的两端分别为第一端20811和第二端20812，在第一端20811和第二端20812之间有凸点20813，所述凸点20813位于所述插接腔2011内，用于与所述光电复合连接器100的导电端子4电连接；所述导电元件2081的第二端20812位于所述适配器200的外表面，用于与集成电路板电连接。所述导电元件2081的第一端20811和外壳201的限位槽2017配合，限制导电元件2081的第一端20811的移动，使得导电元件2081的凸点20813正确的进入本体1的开口14，所述导电元件2081的第一端20811收容于限位槽2017内，该第一端20811不超过外壳201的外表面。
本实施例中，在适配器200上将电组件208布置于适配器200的一侧，且导电元件2081形成弹性悬臂，可以贯通连接器两端或和集成电路板连接。
进一步，也可以在适配器200上引出引脚，用于安装在电路板上，通过电路板向连接器供电或者连接器供电到电路板。
进一步，所述推杆2022还可以包括柄，所述柄用于方便操作。
需要说明的是，所述适配器200的一端用于插入上述光电复合连接器100，适配器200的另一端用于插入另一个光电复合连接器100，由于这两个光电复合连接器100都存在以上提及的弹簧33，因此，当该适配器200也插入了另一个光电复合连接器100的情况下，在两个光电复合连接器100上的两个弹簧33的作用下，两个光电复合连接器100都会受到被推出适配器200的作用力，因此，当上述锁紧件2021离开锁紧槽19时，该光电复合连接器100会在该作用力的作用下，向 脱离适配器200的方向移动，从而脱离了与适配器200之间的固定，即实现了解锁。
本发明实施例中的适配器200可以为光电适配器200，也可以为光纤73适配器200，其中，光电适配器200能够与上述光电复合连接器100相适配，其集成了光纤73适配器200功能和电适配器200功能；光纤73适配器200能够与光纤73连接器相适配；使得适配器200不仅能够与上述的光电复合连接器100匹配，还能够匹配未安装导电端子4的光纤连接器(参见图19所示)。
