Abstract: The present application discloses a connector, which is mounted to a first object and connected between an outlet device and an inlet device to direct a fluid. The connector comprises: a housing mounted to the first object; a pipeline penetrating the housing in a flow direction of the fluid and comprising an outlet end connected to the outlet device and an inlet end connected to the inlet device; a floating device disposed on the housing and floatingly connected to the pipeline, allowing the pipeline to float in the radial direction transverse to a flow direction of the fluid with respect to the housing. The present application also discloses a connecting system.

Abstract: The present application discloses a locking device including: a mounting seat; a locking member, rotatable around an axial direction and movable in the axial direction, when the locking member is in a first axial position and a first rotational position, the locking member is retracted into the mounting seat along the axial direction, and the mounting seat prevents the locking member from rotating around the axial direction; and when the locking member is in a second axial position and a second rotational position, at least a portion of the locking member extends in the axial direction from the mounting seat, to be inserted into and engaged with a second object, and the mounting seat prevents the locking member from moving in the axial direction; and a compression torsional spring biasing the locking member toward the first axial position and the second rotational position.

Abstract: A latch for releasably locking a first object to a second object is disclosed.

Abstract: A captive fastener attachable to a panel along a fastener axis is provided. The captive fastener includes a fastener having a head portion and a shaft extending from the head portion and along the fastener axis. The captive fastener also includes a knob having a proximal end portion engaged to the head portion of the fastener and an annular portion extending radially around the fastener axis and the shaft of the fastener. A ferrule is associated with the knob, the ferrule defining an opening extending along the fastener axis and receiving the shaft of the fastener. The ferrule has a proximal end portion configured to prevent separation of the knob from the ferrule along the fastener axis and a distal end portion configured for engagement to the panel. A spring is positioned to bias the knob or the fastener proximally relative to the ferrule and to inhibit tilting of the knob or the fastener relative to the fastener axis.
