This connection device (D) comprises a shaft (17) which is mobile in translation, a piston (19) integral with the shaft (17), a sleeve (35) which extends around the shaft (17), this sleeve being movable between a rear position and a forward position, and locking members housed in the sleeve (35), each locking member being movable relative to the sleeve between a locking configuration and a release configuration. The shaft (17) is movable between a disconnected position in which the shaft (17) does not oppose movement of the locking members to their release configuration, and the sleeve (35) is in the forward position, and a connected position in which the shaft (17) opposes movement of the locking members into their release configuration and the sleeve (35) is in the rear position, through an intermediate position, in which the shaft (17) opposes movement of the locking members into their release configuration and the sleeve (35) is in the forward position.

A water supply device (10) and a tube connector structure (2) thereof, which are used for an electronic device (100) having a water inlet (101) and a water outlet (102), are disclosed. The tube connector structure (2) includes a connecting plate (21) and two tube connector plugs (22) passing through and fixed to the connecting plate (21). One of the tube connector plugs (22) is connected with the water inlet (101), and the other one of the tube connector plugs (22) is connected with the water outlet (102). Therefore, advantages of rapid connection and disconnection between the water supply device (10) and the tube connector structure (2) and saving time and labor in assembling may be accomplished.

A coupling mechanism securing a first object having a well to a second object having a lug, including a shuttle movable within the lug, a resilient biasing means biasing the shuttle away from a base of the well when the lug is inserted, and locking elements movable radially in the lug between a retracted position and an extended position. Each locking element moves from the retracted position and retains in the extended position by a surface profile of the shuttle. The coupling mechanism includes a movable stop having: a first position in which movement of the shuttle is limited so the locking elements interact with the surface profile, and a second position in which movement of the shuttle is extended to cause the locking elements to interact with another surface profile of the shuttle, moving the locking elements from their extended position to their retracted position.

A male joint includes a male joint main body and a valve element provided coaxially with a central axis of the male joint main body. The valve element includes a shaft portion and a valve portion coaxially provided at a tip end of the shaft portion. The valve portion has a first surface intersecting with the central axis and a second surface that is connected to an outer edge of the first surface and extends along the central axis from the first surface to a base end at a base end portion. The valve portion further comprising a groove having an annular shape centered on the central axis at a side portion and a deformation portion on a base end side of the groove.

Disclosed herein are embodiments of a connector system for releasably connecting together tubes, for example medical tubing, and methods of making and using such a connector system, whereby the connector system includes a female coupler having a first passageway, a male coupler having a second passageway, a catch movably coupled to the female coupler, and a catch-receiving element coupled to the male coupler. The connector system further includes a release element movably coupled to the female coupler, whereby travel of the release element along or over a female coupler outer surface of the female coupler disengages the catch from the catch-receiving element to achieve a disconnected condition of the connector system. Further disclosed herein are embodiments of a connector system for releasably connecting together tubes, whereby the connector system includes at least one valve biased by a valve-biasing member disposed external to or outside of the fluid flow path.

A connector including a plug and a socket. The socket includes: a socket body having an insertion hole formed therein; a columnar rotary valve inserted into the insertion hole; and a switching mechanism for switching an open state and a closed state. The rotary valve includes a pair of convex portions respectively in contact with both ends of the insertion hole to seal an outflow of a liquid; and a concave portion provided between the pair of convex portions and forming a cleaning space) in which a cleaning fluid is circulated between the concave portion and an inner peripheral surface of the insertion hole. The socket body includes a cleaning fluid inflow passage for guiding the cleaning fluid to the cleaning space and a cleaning fluid outflow passage through which the cleaning fluid flows out of the cleaning space.

A quick connector is described to removably connect hydraulic equipment operating in underground coal mines, wherein two tubular bodies are coupled to each other such as to define one individual fluid passage, a tubular element is movable between a closed position and an open position in which it either blocks or allows a relative axial movement between the tubular bodies, respectively, and a safety member slides on the tubular element between at least one safety position and a freedom position, wherein it either blocks or allows the tubular to element to move to the open position, respectively.
