A female element for a fluidic connector, the female element being designed to be connected to a Schrader-type male fitting, the male fitting comprising a tubular part with threading and housing a valve with a valve opening pin, the female element comprising:
- a main body, which provides a first passage extending along a longitudinal axis, the main body comprising a distal portion and a proximal portion, which are aligned along the longitudinal axis, the first passage opening from the distal portion through a distal mouth, the main body being configured to receive the male fitting in the first passage through the distal mouth, the male fitting being in an engaged position relative to the female element,
- the distal portion providing a housing, which extends from an outside of the main body along a locking axis radial to the longitudinal axis and which opens into the first passage,
- an adapter, which is traversed by a second passage, and which comprises:
- a proximal part, from which the second passage opens, and which comprises securing means, which are intended for the fluidic connection of the adapter to a pipeline,
- an intermediate part, which comprises assembly means, by which the adapter is able to be assembled to the proximal portion of the main body, in an assembled configuration of the female element,
- a distal part, which provides a pusher, the pusher extending, in the first passage, from the intermediate part towards the distal mouth when the female element is in an assembled configuration, the second passage opening from the pusher, so that when the adapter is assembled to the main body, the first passage and the second passage together form an internal channel of the female element, the pusher being able to push the pin of the male fitting when connecting the male fitting to the female element,
- a lock, which is assembled to the distal portion, and which comprises:
- a locking portion, which is received in the first passage and in which an opening is provided, which extends along an opening axis, and which defines a passage ring for the male fitting in an engaged position,
- a retaining relief, which extends protruding into the opening, and which is able to penetrate the threading of the male fitting,
- an actuation surface opposite the retaining relief relative to the opening axis,
- the lock being received in the housing and being translatable relative to the main body along the locking axis, between:
- a locking position, wherein, when the male fitting is received in the distal mouth in an engaged position, the retaining relief penetrates the threading of the male fitting to maintain the male fitting in an engaged position, and
- an unlocking position, wherein the retaining relief releases the threading of the male fitting and does not oppose a withdrawal of the male fitting from the main body,
- a return member, which is configured to return the lock from its unlocking position to its locking position,
- an annular seal, which is arranged around the pusher in contact with an axial surface of the adapter, the axial surface being oriented towards the distal mouth and being carried by a plane perpendicular to the longitudinal axis, the annular seal being configured to cooperate with the tubular part of the male fitting in an engaged position to ensure sealing between the male fitting and the adapter,
- wherein:
- the female element also comprises a lock stop, the lock stop comprising:
- an annular distal part, which is guided in the main body and which extends, along the longitudinal axis, in the housing of the main body and in the opening of the lock, the annular distal part cooperating with the locking portion to allow movements of the lock between the locking position and the unlocking position, while preventing movements beyond the locking position, and,
- an internal bore, which surrounds the pusher, and which is intended to receive the tubular part of the male fitting,
- the annular seal is placed between the internal bore of the lock stop and the pusher.
