具体实施方式
下面将结合本申请实施例中的附图，对本申请实施例中的技术方案进行清楚、完整地描述，显然，所描述的实施例仅仅是本申请的一部分实施例，而不是全部的实施例。基于本申请中的实施例，本领域普通技术人员在没有作出创造性劳动前提下所获得的所有其他实施例，都属于本申请保护的范围。
需要说明，本申请实施例中所有方向性指示(诸如上、下、左、右、前、后……)仅用于解释在某一特定姿态下各部件之间的相对位置关系、运动情况 等，如果该特定姿态发生改变时，则该方向性指示也相应地随之改变。
还需要说明的是，当元件被称为“固定于”或“设置于”另一个元件上时，它可以直接在另一个元件上或者可能同时存在居中元件。当一个元件被称为是“连接”另一个元件，它可以是直接连接另一个元件或者也可以是通过居中元件间接连接另一个元件。
另外，在本申请中涉及“第一”、“第二”等的描述仅用于描述目的，而不能理解为指示或暗示其相对重要性或者隐含指明所指示的技术特征的数量。由此，限定有“第一”、“第二”的特征可以明示或者隐含地包括至少一个该特征。另外，各个实施例之间的技术方案可以相互结合，但是必须是以本领域普通技术人员能够实现为基础，当技术方案的结合出现相互矛盾或无法实现时应当认为这种技术方案的结合不存在，也不在本申请要求的保护范围之内。
如图1-4所示，本申请实施例提供的接头100，包括第一接头本体110、球体120以及网状挡板130，第一接头本体110具有中空内腔1101、设于中空内腔1101一端的第一入口1102、设于另一端的第一出口1103，网状挡板130设于中空内腔1101内且网状挡板130设有多个第一流通孔131，中空内腔1101内凸设有位于第一入口1102与网状挡板130之间的环状凸起部1104，环状凸起部1104围合形成环形通孔1112，环形通孔1112的直径和第一流通孔131的直径都小于球体120的直径，球体120置于环状凸起部1104和网状挡板130之间。
网状挡板130的外形为圆形，安装于第一接头本体110的中空内腔1101内，且网状挡板130设有多个第一流通孔131，且第一流通孔131的直径小于球体120的直径，这样的结构能够对球体120进行限位的同时还不会妨碍第一接头本体110内的流体流通；此外，网状挡板130能够过滤管道中的杂质。中空内腔1101内形成的环状凸起部1104是沿第一接头本体110的管壁环状成型的，围合形成一环形通孔1112，且环形通孔1112的直径比球体120的直径小，这样的结构能够对球体120进行限位的同时还不会妨碍第一管体111内的流体流 通。第一接头本体110、球体120和网状挡板130共同构成的结构及其原理类似于单向阀，能够实现流体只能朝一个方向流通的效果。另外需要说明的是，第一管体111可通过注塑成型的方式加工出来。
如图1、图2和图4-6所示，作为一种实施方式，第一接头本体110包括第一管体111和与第一管体111连接的第二管体112；第二管体112包括连接部1121和顶针部1122，连接部1121的一端与第一管体111之远离网状挡板130的一端连接，连接部1121的另一端与顶针部1122连接，顶针部1122用于插入第二接头220内并顶开第二接头220的弹性挡圈222；第一入口1102设于第一管体111之靠近第二管体112的一端，第一出口1103设于第一管体111之远离第二管体112的一端。设置第二管体112的作用是为了与第二接头220配合使用，使得流体能够在管路流通。需要说明的是，顶针部1122和连接部1121上都设有与第一管体111的管壁连通的通道用于流体流通。
如图1和图4-6所示，作为一种实施方式，连接部1121包括第一连接部1105和第二连接部1106，第一连接部1105与第一管体111之远离近网状挡板130的一端连接，第二连接部1106用于连接第一连接部1105与顶针部1122。本实施例提供的顶针部1122的直径小于第一连接部1105的直径，目的是使顶针部1122能够插入第二接头220的管壁内并顶开第二接头220内的弹性挡圈222，让管道形成通路。第一连接部1105是与第一管体111连接的部分，第二连接部1106则是连接第一连接部1105与顶针部1122。
如图1和4所示，作为一种实施方式，第二连接部1106呈圆锥形，第二连接部1106包括与第一连接部1105连接的第一端部1107、与顶针部1122连接且直径小于第一端部1107直径的第二端部1108和连接第一端部1107于第二端部1108的锥形侧部1109，在锥形侧部1109上贯穿设有至少一个用于流体通过的第二流通孔1110。需要说明的是，第二管体112内的流体可同时从顶针部1122的通道内和第二连接部1106的第二流通孔1110内通过，在第二连接部1106设置第二流通孔1110是为了加大流体在单位时间内通过的流量。第二连接部 1106呈圆锥形是基于保证顶针部1122的直径比第一连接部1105的直径小这样一个前提所做的过渡连接部位。
如图1和3所示，作为一种实施方式，第一管体111之远离第二管体112的一端设有用于安装网状挡板130的第一槽口1111。第一槽口1111设于第一管体111之远离第二管体112的端面上，且沿着第一管体111的管壁呈环状，第一槽口1111的直径略大于网状挡板130的直径使网状挡板130能够放置于第一槽口1111中。在本实施例中，网状挡板130通过焊接与第一槽口1111连接，焊接的结构刚度大且操作简单方便，故在采用焊接，当然，在具体应用中，不限于只采用焊接，例如，作为一种替代方案，也可以采用粘接的方式连接。
如图1和2所示，作为一种实施方式，第一管体111与第二管体112通过焊接的方式连接。本实施采用焊接的方式连接第一管体111和第二管体112，焊接的密闭性好，结构刚度大且操作简单方便，故在采用焊接，当然，在具体应用中，不限于只采用焊接，例如，作为一种替代方案，也可以是焊接、粘接或螺纹连接的至少一种方式连接。
本申请实施例提供的接头100的有益效果：接头100包括第一接头本体110、球体120以及网状挡板130，第一接头本体110设有中空内腔1101，网状挡板130设有多个第一流通孔131，中空内腔1101内凸设有环状凸起部1104，环状凸起部1104形成环形通孔1112，且环形通孔1112的直径和第一流通孔131的直径都小于球体120的直径，球体120放置于中空内腔1101中并通过环状凸起部1104和网状挡板130进行限位，流体从第一入口1102进入，球体120在第一接头本体110的管壁内的流体压力的作用下远离环形通孔1112形成通路，流体从靠近网状挡板130一端进入，球体120在第一接头本体110的管壁内的流体压力的作用下封堵环形通孔1112，从而防止了在接头100断开时流体从进水口311倒流出来发生喷溅。
如图1和图4-7所示，本申请实施例提供的接头组件200，包括：
第一接头210，第一接头210采用上述的接头100；
第二接头220，第二接头220包括第三管体221和安装于第三管体221内的弹性挡圈222；弹性挡圈222设有多个沿周向间隔分布以用于将弹性挡圈222分割形成多个叶片的切口，第一接头210之远离网状挡板130一端与第二接头220可拆卸连接，并且第一接头210与第二接头220连接时顶针部1122插入第三管体221内将弹性挡圈222顶开以连通第一接头210与第二接头220；第一接头210与第二接头220断开连接时，第三管体221内的弹性挡圈222闭合以阻断第一接头210与第二接头220。
本实施例的弹性挡圈222是由弹性材料制成的，呈圆形用以适配第三管体221的管道，弹性挡圈222上设有的多个沿周向间隔分布的切口将弹性挡圈222分割形成多个叶片，当第一接头210与第二接头220连接时，弹性挡圈222的多个叶片在顶针部1122的外力作用下产生变形使其切口缝隙增大从而实现通路；当第一接头210与第二接头220连接时，顶针部1122远离弹性挡圈222，弹性挡圈222的多个叶片恢复原状使其切口缝隙变小从而实现断路。需要说明的是，第一接头210与第二接头220断开连接时，弹性挡圈222闭合只能阻挡接头断开时出水口312处的流体发生喷溅，而不能阻止流体从入水口渗透出来，因为本申请的目的是为了防止接头断开时喷溅出的液体会对挖矿机造成损坏，因此，在本申请中，只需要做到接头断开时出水口312处的流体不会喷溅出来就能达到目的。
如图5和6所示，作为一种实施方式，接头组件200还包括活接螺母230，活接螺母230用于可拆卸连接第一接头210和第二接头220。第一接头210和第二接头220与活接螺母230相连接处设有与活接螺母230适配的外螺纹。可拆卸连接时为了能够在需要的情况下方便把外接管路拆下来。
如图6和7所示，作为一种实施方式，第三管体221设有用于安装弹性挡圈222的第二槽口2211。需要说明的是，由于弹性挡圈222是可变形的弹性材料制成，且弹性挡圈222的直径略小于第二槽口2211的直径以保证弹性挡圈222能放入第二槽口2211中，另外，弹性挡圈222与第二槽口2211通过粘接 的方式连接。
本申请实施例提供的接头组件200的有益效果：接头组件200包括第一接头210和第二接头220，第一接头210采用上述的接头100，第二接头220包括弹性挡圈222，弹性挡圈222设有多个沿周向间隔分布以用于将弹性挡圈222分割形成多个叶片的切口，第一接头210与第二接头220连接时顶针部1122插入第三管体221内将弹性挡圈222顶开以连通第一接头210与第二接头220；第一接头210与第二接头220断开连接时，弹性挡圈222闭合以阻断第一接头210与第二接头220；从而保证在第一接头210与第二接头220断开时，第一接头210处与第二接头220处的流体都不会发生喷溅。
如图5和图8所示，本申请实施例提供的液冷板300，包括液冷板本体310和与液冷板本体310连接的至少一个上述接头组件200。
具体应用中，本实施例提供的液冷板300，包括：
液冷板本体310，液冷板本体310上设有至少一个进水口311和至少一个出水口312；
进水管320，进水管320用于输送流体至液冷板本体310内；
出水管330，出水管330用于将液冷板本体310内的流体输出至外界；
第一接头组件340，第一接头组件340采用上述的接头组件200；第一接头组件340的第一接头210与进水口311连接，第一接头组件340的第二接头220与进水管320连接；
第二接头组件350，第一接头组件340采用上述的接头组件200；第二接头组件350的第二接头220的一端与出水口312连接，第二接头组件350的第一接头210的一端与出水管330连接。
需要说明的是，第一接头组件340和第二接头组件350都是上述的接头组件200，区别在于，第一接头组件340是靠近第一接头210的一端连接进水口311，第二接头组件350是第一接头210的一端连接出水口312，即连接进水口311和出水口312的接头组件200方向是相反的；本实施例提供的液冷板本体 310设有一个进水口311和一个出水口312，相对应的，第一接头组件340和进水管320的数量与进水口311的数量相同，第二接头组件350和出水管330的数量与出水口312的数量相同，当然，在具体应用中，进水口311和出水口312的数量不限于此，例如，作为一种替代方案，也可以设有两个进水口311，一个出水口312，与之相对应的，第一接头组件340和进水管320的数量都是两个，第二接头组件350和出水管330的数量都是一个。
如图1、图5、图8和图9所示，本申请实施例提供的液冷服务器400，包括电路板410和上述的液冷板300，液冷板300与电路板410导热连接。液冷服务器400也称液体注入服务器，通过冷热交换带走服务器的散热的一种服务器。具体应用中，液冷服务器400应用于挖矿机，挖矿机主要用于挖掘比特币的长期高强度计算机类设备，一般采用水冷和风冷结合的方式，因此在液冷板300的进水口311和出水口312连接上述的接头组件200，可有效防止接头100断开时水喷溅出来淋溅到挖矿机上导致主机容易损坏。
下面结合图1-9说明接头100的工作原理：
接头100连接于进水口311处，当接头100连接时，流体从第一入口1102进入接头100，球体120在第一接头本体110的管壁内的流体压力的作用下远离环形通孔1112形成通路，流体顺利从管道内流通；当接头100断开连接时，流体往第一入口1102方向回流，此时球体120在第一接头本体110的管壁内的流体压力的作用下与环形通孔1112贴合形成断路，从而保证在接头100断开时进水口311的流体不会发生喷溅。
下面结合图1-9-说明接头组件200的工作原理：第一接头210连接于进水口311处，第二接头220连接于出水口312处，当第一接头210与第二接头220连接时，流体从第一入口1102进入第一接头210，球体120在第一接头本体110的管壁内的流体压力的作用下远离环形通孔1112形成通路，第一接头210的顶针部1122插入第三管体221内将弹性挡圈222顶开使第二接头220形成通路，流体顺利从管道内流通；当第一接头210与第二接头220断开连接时，第一接 头210处的流体往第一入口1102方向回流，此时球体120在第一接头本体110的管壁内的流体压力的作用下与环形通孔1112贴合形成断路，第二接头220处的弹性挡圈222由于失去顶针部1122的阻力作用而闭合形成断路阻断流体，从而保证在接头100断开时进水口311和出水口312的流体不会发生喷溅。
以上仅为本申请的优选实施例，并非因此限制本申请的专利范围，凡是在本申请的申请构思下，利用本申请说明书及附图内容所作的等效结构变换，或直接/间接运用在其他相关的技术领域均包括在本申请的专利保护范围内。
