具体实施方式
下面对优选实施方式的描述仅仅是示范性的，而绝不是对本公开及其应用或用法的限制。
图1示出了根据本公开的第一实施方式的液体输注泵和保持装置进行连接的截面图。液体输注泵10与保持装置20通过连接器组件100可拆卸地进行电连接或信号通讯连接，保持装置20可以通过螺纹把手30固定在患者的床头或输液架上，从而为液体输注泵10提供机械支撑的同时为液体输注泵10提供电力并与其通信。图2示出了图1中的液体输注泵10和保持装置20连接部分的局部放大图。液体输注泵10中设置有连接端口11。保持装置20中设置有电路板21。连接器组件100设置在保持装置20中。连接器组件100包括5个针式连接器200和围绕针式连接器的外壳300。其中，连接器200的一端(图2中示为左端)与液体输注泵10中的连接端口11电连接或信号通讯连接。针式连接器200的另一端(图2中示为右端) 与保持装置20中的电路板21电连接或信号通讯连接。
图3-图4示出了根据本公开的第一实施方式的连接器组件100的俯视图和正视图。该针式连接器组件100由间隔一定距离的5个针式连接器200和围绕在5个针式连接器200周围以对针式连接器200进行保持的外壳300构成。优选地，该外壳300是由塑胶制成的。图5示出了图4中沿A-A线的截取的连接器组件100的截面图。其中，针式连接器200包括：连接针201，连接针201用于与液体输注泵10的连接端口11电连接或信号通讯连接；上盖202，上盖202设置在连接针201的相反端，用于与保持装置20的电路板21电连接或信号通讯连接；弹簧203，弹簧203设置在连接针201与上盖202之间，用于对连接针201与上盖202之间施加弹簧力及连接，确保与液体输注泵10的可靠电连接或信号通讯连接。优选地，上盖202由金属制成。外壳300设置在连接针201、上盖202和弹簧203周围以对连接针201、上盖202和弹簧203进行保持。
图6示出了图5中的连接器组件100的局部放大图。上盖202包括上盖本体2021、从上盖本体2021的顶端径向向外延伸的凸缘2022以及设置在凸缘2022上方的杆部2023。外壳300的上部设置有环形的台阶部301。凸缘2022的下表面压靠在台阶部301内侧的水平表面3011上，以限制上盖202的向下移动。台阶部301的顶端径向向内延伸有至少一个固定部302，该固定部302的下表面压靠在凸缘2022的上表面上，以将上盖202牢固地固定在外壳300内。优选地，固定部302的上表面的面积小于台阶部301其余部分的上表面的面积，以使外壳300的台阶部301的除固定部302以外的部分仍可以用于支撑保持装置20的电路板21(未示出)的定位。优选地，由图4所示，每个针式连接器200由多个固定部302压靠。优选地，由图4所示，固定部302沿针式连接器200的周缘均匀分布，以提供对针式连接器200的均匀压力。
根据本公开的第一实施方式的连接器组件100中的固定部302是通过以下加工过程来实现的：采用热熔机等加热工具使外壳300上部的台阶部301顶端的多处小面积部分同时熔化，熔化部分形成径向向内延伸的固定部302，固定部302压靠在上盖202的凸缘2022上，从而将上盖202牢固地固定在外壳300内。
另外，由图6所示，上盖本体2021沿径向向外方向设置有一圈连续的突环2024。突环2024卡在外壳300的内周表面上对应的槽部中，以通过 过盈配合来保持上盖202不被弹簧203顶出。
图7示出了对比示例中的针式连接器组件100的截面图。其中，该连接器组件仅在上盖202的上盖本体2021沿径向向外方向设置有一圈突环2024。突环2024卡在外壳300的内周表面中的凹槽，以通过过盈配合来保持上盖202不被弹簧203顶出。然而在实际使用过程中，上盖202仅通过上述过盈配合来进行保持，其与塑胶外壳300之间存在松动的风险。当上盖202与外壳300之间松动时，会导致弹簧203处于松弛状态，难以将连接针201顶出，从而容易与泵10的连接端口11断开连接，从而使液体输注泵10与保持装置20之间存在接触不良的风险。
与图7的对比示例中的针式连接器组件100相比，本公开通过固定部302和突环2024的双重设计，使上盖202牢固地保持在外壳300中，从而使处于上盖202下部的弹簧203处于压紧状态，为处于弹簧203下部的连接针201提供足以使其顶出的弹簧力，以使连接针201与泵10的连接端口11连接牢固，从而使液体输注泵10与保持装置20之间连接牢固。
图8示出了根据本公开的第二实施方式的连接器组件100的俯视图。该连接器组件100由2个针式连接器200和围绕在2个针式连接器200周围以对针式连接器200进行保持的外壳300构成。该实施方式的连接器组件200的其余结构与第一实施方式中的相应结构相同。连接器组件100可以按照实际的设计需要包括2个或5个以外数量的多个针式连接器200。
尽管在此已详细描述本公开的各种实施方式，但是应该理解本公开并不局限于这里详细描述和示出的具体实施方式，在不偏离本公开的实质和范围的情况下可由本领域的技术人员实现其它的变型和变体。所有这些变型和变体都落入本公开的范围内。而且，所有在此描述的构件都可以由其他技术性上等同的构件来代替。
