    • A clamping system and method for use in a fluid coupling assembly may include redundant locking features for connecting adjacent ends of fluid conduits such as aircraft fuel lines. The exemplary clamping system (20) may make use of two draw latch mechanisms (28,28') that each separately apply a spring loaded clamping force to a flex band assembly (25) through corresponding draw springs (40,40') which oppose one another. Thus, either latch mechanism (28,28') may provide a draw latch function by providing a clamping force to the flex band assembly (25), which in turn holds the end flanges (32,34) of the fluid conduits (22,24) together, thereby providing a sealing connection to facilitate the transfer of a fluid there between. Using two opposed draw latch mechanisms (28,28') provides for redundant clamping forces such that the failure of one of the mechanisms does not result in an inadvertent disconnection of the fluid conduits one from the other.
    • 用于流体联接组件的夹紧系统和方法可以包括用于连接诸如飞行器燃料管线的流体导管的相邻端部的冗余锁定特征。 示例性的夹紧系统(20)可以利用两个牵引闩锁机构(28,28'),每个牵引闩锁机构(28,28')通过相应的拉伸弹簧(40,40')分别施加弹簧加载的夹紧力到柔性带组件(25) 另一个。 因此,任一个闩锁机构(28,28')可以通过向柔性带组件(25)提供夹紧力来提供牵引闩锁功能,弹性带组件(25)又将流体导管(22,28')的端部凸缘(32,34) 24)在一起,从而提供密封连接以促进其间的流体的传递。 使用两个相对的拉出闩锁机构(28,28')提供冗余夹紧力,使得其中一个机构的故障不会导致流体导管与另一个之间的意外断开。
