Connector unit comprising two connector parts
View Patent ↗A connector unit having a first connector part and at least a second connector part, wherein the first connector part and the at least second connector part are connectable during a mating of the first connector part and the at least second connector part and are dis-connectable during a de-mating of the first connector part and the at least second connector part, and further having at least a first locking assembly for locking the first connector part and the at least second connector part at least during the de-mate of the first connector part and the at least second connector part. At least first locking assembly has at least a first hydraulic lock.
1. A connector unit comprising:
a first connector part and a second connector part,
wherein the first connector part and the second connector part are connectable during a mating of the first connector part and the second connector part and are dis-connectable during a de-mating of the first connector part and the second connector part, and
a first locking assembly for locking a portion of the first connector part and a portion of the second connector part together at least during a portion of the de-mating of the first connector part and the second connector part,
wherein the first locking assembly comprises a first hydraulic lock,
wherein the first hydraulic lock comprises a balancing chamber and a valve via which the balancing chamber is fillable and unfillable with an uncompressible fluid.
2. The connector unit according to claim 1 ,
wherein the balancing chamber of the first hydraulic lock is encased by a housing and a piston being guided in the housing.
3. The connector unit according to claim 2 ,
wherein the first locking assembly comprises a first bias device that is arranged in the balancing chamber and that contacts a part of the balancing chamber and is biased against the piston.
4. The connector unit according to claim 2 ,
wherein the housing is arranged in the second connector part and wherein the second connector part is a female part of the connector unit.
5. The connector unit according to claim 1 ,
wherein the valve comprises a first housing part and a second housing part and wherein the first housing part and the second housing part are arranged movable relative to each other.
6. The connector unit according to claim 5 ,
wherein the first housing part comprises a conical aperture and wherein the second housing part comprises a plug and wherein the conical aperture mounts the plug in a closed state of the valve and wherein the conical aperture is free of the plug in an open state of the valve.
7. The connector unit according to claim 5 ,
wherein the second housing part of the valve is held in position by a bias device.
8. The connector unit according to claim 5 ,
wherein one of the housing parts of the valve is arranged moveably and wherein another of the housing parts of the valve is arranged fixed relative to a housing of the connector unit.
9. The connector unit according to claim 1 ,
wherein the first connector part comprises an element that establishes a second lock of the first locking assembly during the portion of the de-mating of the first connector part and the second connector part.
10. The connector unit according to claim 9 ,
wherein the second lock comprises a second hydraulic lock.
11. The connector unit according to claim 10 ,
wherein the second hydraulic lock comprises a balancing chamber being encased by a second hydraulic lock housing and wherein the second hydraulic lock comprises a piston being guided in the second hydraulic lock housing and wherein the second hydraulic lock comprises a first seal and a second seal, wherein the first seal is arranged at the second hydraulic lock housing and wherein the second seal is arranged at the second hydraulic lock piston.
12. A method for operating a connector unit comprising a first connector part and a second connector part, wherein the first connector part and the second connector part are connectable during a mating of the first connector part and the second connector part and are dis-connectable during a de-mating of the first connector part and the second connector part, and further comprising a first locking assembly for locking a portion of the first connector part and a portion of the second connector part at least during a portion of the de-mating of the first connector part and the second connector part, the method comprising:
pushing the first connector part into the second connector part, and thus
closing a first hydraulic lock of the first locking assembly, and thus
locking the first connector part and the second connector part with each other, and then
pulling the first connector part from the second connector part, and thus
opening the first hydraulic lock by using a second hydraulic lock of the first locking assembly, and thus
unlocking the first connector part and the second connector part.
13. The method according to claim 12 , further comprising:
activating the first hydraulic lock by the mating of the first connector part and the second connector part.
