Abstract

Device for fitting two connectors at the end of two conduits, particularly in an aircraft, with a view to subsequent mutual connection of the connectors by a connecting pipe, including a body; a first support including temporary connector retainers that define an associated connector axis; an opposite second support including temporary connector retainers that define an associated connector axis; structure for moving the first support in translation relative to the body parallel to the associated connector axis, between a retracted position and a deployed position. A method of establishing fluidic communication between two conduits in an aircraft, including fitting two connectors at the end of the two conduits by such a device.

First claim

The invention claimed is:

1. A method of fitting two connectors to the end of two respective conduits in an aircraft, in a manner enabling subsequent mutual connection of the connectors by a connecting pipe, wherein the method includes:
providing a device including:
a body;
a first connector support mounted on a first end part of the body and including temporary connector retainers that define a first connector axis;
a second connector support connected to a second end part of the body opposite the first end part thereof and including temporary connector retainers that define a second connector axis; and
structure for moving the first connector support in translation relative to the body of the device, parallel to the first connector axis, between a retracted position and a deployed position,
wherein the first and second connector axes coincide;

fixing the two connectors to the respective two connector supports of the device, by the corresponding temporary connector retainers;
positioning the device equipped with the connectors so as to dispose each of the connectors onto the corresponding conduit so that each corresponding connector axis is aligned with an axis of the corresponding conduit;
moving the first connector support relative to the body of the device, as far as its deployed position;
fitting each connector into the corresponding conduit; and
disengaging the temporary retainer from each connector support so as to release each of the two connectors.

2. The method according to claim 1 , wherein the structure for moving the first connector support includes:
a nut rotatably mounted and fixed in translation on the first end part of the body of the device;
a rod fastened to the first connector support and screwed into the nut;
a cam follower fastened to a first element selected from the rod and the body of the device; and
a cam fastened to the other element selected from the rod and the body of the device and configured to enable guiding of the cam follower in translation parallel to the first connector axis;
wherein movement of the first connector support relative to the body of the device is effected by a movement in rotation of the nut relative to the body.

3. The method according to claim 1 , wherein the device further includes structure for moving the second connector support in translation relative to the body of the device, parallel to the second connector axis, and a lock for locking the position of this second connector support relative to the body,
the method including a preliminary step of adjusting the length of the device including:
moving the second connector support of the device in translation relative to the body of this device, parallel to the second connector axis; then
activating the lock for locking the position of the second connector support relative to the body.

4. The method according to claim 3 , wherein:
the structure for moving the second connector support in translation relative to the body of the device includes a tube fastened to the second connector support and in or on which the body is slidably mounted, the lock being configured to lock the position of the tube relative to the body, and
movement of the second connector support of the device is produced by a sliding movement of the body of the device in or on the tube fastened to the second connector support.

5. The method according to claim 1 , wherein the temporary connector retainers of at least one of the connector supports include mobile connector clamping members, and wherein fixing of the corresponding connector to the at least one connector support is effected by movement of the mobile connector clamping members.

6. A method of establishing fluidic communication between two conduits in an aircraft, including:
fitting two connectors to an end of two respective conduits using a device comprising:
a body;
a first connector support mounted on a first end part of the body and including temporary connector retainers that define a first connector axis;
a second connector support connected to a second end part of the body opposite the first end part thereof and including temporary connector retainers that define a second connector axis; and
structure for moving the first connector support in translation relative to the body of the device, parallel to the first connector axis, between a retracted position and a deployed position,
wherein the first and second connector axes coincide;

fixing the two connectors to the respective two connector supports of the device, by the corresponding temporary connector retainers;
positioning the device equipped with the connectors so as to dispose each of the connectors onto the corresponding conduit so that each corresponding connector axis is aligned with an axis of the corresponding conduit;
moving the first connector support relative to the body of the device, as far as its deployed position;
fitting each connector into the corresponding conduit;
disengaging the temporary retainer from each connector support so as to release each of the two connectors;
positioning a connecting pipe between the two connectors in alignment therewith; and
fixing opposite ends of the connecting pipe to the respective two connectors.

7. A device for fitting two connectors to the end of two respective conduits in an aircraft, in a manner enabling subsequent mutual connection of the connectors by a connecting pipe, comprising:
a body;
a first connector support mounted on a first end part of the body and including temporary connector retainers that define a first connector axis and that include mobile connector clamping members;
a second connector support connected to a second end part of the body opposite the first end part thereof and including temporary connector retainers that define a second connector axis and that include mobile connector clamping members; and
structure for moving the first connector support in translation relative to the body of the device, parallel to the first connector axis, between a retracted position and a deployed position,
wherein the first and second connector axes coincide.

8. The device according to claim 7 , wherein at least one of the first and second connector supports takes the form of a plate.

9. The device according to claim 8 , wherein the mobile connector clamping members of the at least one connector support are slidably mounted in two respective diametrically opposite openings in the plate and each extending in a direction having at least one radial component relative to the corresponding connector axis.

10. The device according to claim 8 , wherein temporary retainers of the plate include at least one centering groove formed in a distal face of the plate opposite the body and conformed to receive an end lip of a connector.

11. The device according to claim 7 , further including structure for moving the second connector support in translation relative to the body of the device, parallel to the second connector axis, and a lock for locking the position of this second connector support relative to the body.

12. The device according to claim 11 , wherein the structure for moving the second connector support in translation relative to the body of the device includes a tube fastened to the second connector support and in or on which the body is slidably mounted, the lock being configured to lock the position of the tube relative to the body.

13. The device according to claim 7 , wherein the temporary connector retainers of at least one of the connector supports are adapted to center relative to the corresponding connector axis connectors of at least two types differin
