An adaptable liquid connector structure includes a case, an intermediate member and a liquid connector main body. The case is a hollow frame. The intermediate member is located in the case and includes an opening formed at a front area thereof for mounting the liquid connector main body therein, a locating bore located below the opening, and a plurality of elastic elements mounted on outer sides and a rear side of thereof. The intermediate member is supported by the elastic elements to suspend in the case and the elastic elements absorb assembly tolerance of the adaptable liquid connector structure, such that the liquid connector main body mounted therein is allowed for a positional floating adjustment in and relative to the case upward, downward, leftward and rightward to be smoothly, correctly and securely connected to an adaptor connector.

Some fluid coupling devices described herein are configured as non-spill fluid couplings. In addition, some embodiments described in this document relate to fluid coupling devices that are constructed modularly, and to modules that can be universally incorporated into the construction of multiple different types of fluid couplings. Further, fluid handling component coupling members are described.

A non-circular disconnect, comprising: a male body to insert into a non-circular female disconnect; a male poppet, wherein: when the non-circular disconnect is not inserted into the non-circular female disconnect, the male poppet is held in place, via spring force, at an opening of the non-circular male body to create a seal to prevent leakage; and when the non-circular disconnect is inserted into the non-circular female disconnect, the male poppet is pushed inwards, to allow for liquid to flow through the non-circular disconnect, by a plunger in the non-circular female disconnect.

A quick connector includes a male base and a female base, wherein the male base has a first tube body, an annular clamping groove arranged outside the first tube body, a first flow channel axially penetrating through the first tube body, a plug body slidably arranged in the first flow channel, and an elastic member for pushing the plug body to close the first flow channel. The female base includes a second tube body, a second flow channel which axially penetrates through the second tube body and into which the first tube body is inserted, an annular fastener provided in the second flow channel, and a push rod fixed on the second flow channel and oriented towards the plug body.

A quick disconnect system includes a housing and a first connector of a quick disconnect configured to complementarily mate with a second connector of the quick disconnect. A pre-loaded biasing element is configured to provide a biasing force between the first connector and the housing. A method for mating a quick disconnect is also described. The method includes receiving a connecting force to mate a first connector of a quick disconnect in a housing with a second connector of the quick disconnect. When the connecting force is at least equal to or greater than a mating force value, the first connector is mated with the second connector. When the connecting force is greater than a pre-load value of a biasing element in the housing, the mated quick disconnect is moved relative to the housing while maintaining the connection of the mated quick disconnect.

A coupling member for a blind mate fluid coupling includes a housing and a fluid connector fixed in position relative to the housing for connecting to a fluid conduit of the system. A valve body extends through the housing and is movable relative to the housing. The valve body includes an internal fluid passage that is fluidly connected to the connector, and a valve member opens or closes the internal fluid passage. A carrier is at least partially disposed in the housing and is radially movable relative to the housing. The carrier is configured to cooperate with the valve body to facilitate alignment of the valve body when coupling to another coupling member. The carrier may form a portion of the fluid passage between the connector and valve body, and includes a sealing arrangement that permits radial and/or angular misalignment compensation of the design. Varying diameters of the insertion part or receiving part of the coupling member may be provided for further enhancing misalignment compensation of the design.
