Blind mate mechanism
Blind mate mechanisms that are capable of simultaneously making multiple connections in a single motion are disclosed. Such mechanisms may be useful for applications where two or more of structural, electrical, and/or fluid couplings could be made manually or robotically at the same time using the mechanism. The mechanism may include a removable side and a fixed side.
1. A blind mate mechanism, comprising:
a removable side, comprising
a drive bolt, and
one or more first connectors; and
a fixed side operably connected to a device to be serviced, the fixed side comprising:
a threaded receiving interface configured to receive the drive bolt, and
one or more second connectors configured to connect with the one or more first connectors, wherein
the removable side is configured to be mated with the fixed side and de-mated with the fixed side, and
the fixed side and the removable side are configured to facilitate mechanical and structural connections, transfer of fluids, transfer of communications signals, transfer of power, or any combination thereof, between the fixed side and the removable side via the one or more first connectors and the one or more second connectors when the fixed side and the removable side are mated; wherein
the fixed side further comprises a carriage and a carriage retainer, and
the carriage comprises cylinders surrounding needle roller bearings mounted with pins, the cylinders configured to allow the carriage to roll up and down along the carriage retainer.
2. The blind mate mechanism of claim 1 , wherein the removable side and the fixed side further comprise dust/debris gates for the one or more first connectors and the one or more second connectors, respectively.
3. The blind mate mechanism of claim 1 , further comprising:
a coarse alignment feature comprising projections on the fixed side and corresponding holes on the removable side, or vice versa; and
a fine alignment feature comprising a cutout on the removable side and a corresponding boss on the fixed side, or vice versa.
4. The blind mate mechanism of claim 1 , wherein the fixed side further comprises:
a carriage configured to carry the one or more second connectors and to allow the drive bolt to drive the one or more first connectors and the one or more second connectors together in the mated configuration.
5. The blind mate mechanism of claim 4 , wherein
the fixed side further comprises a fine alignment feature comprising pins, and
the carriage further comprises carriage return springs operably connected to the fine alignment feature.
6. The blind mate mechanism of claim 1 , further comprising:
connector over-travel protectors comprising lower movement limiting posts, upper movement limiting posts, and springs, the connector over-travel protectors configured to prevent the one or more second connectors from overextension or overcompression.
7. The blind mate mechanism of claim 1 , wherein the fixed side further comprises:
a status indicator comprising legs biased by springs, the status indicator configured to indicate when the fixed side and the removable side are properly aligned.
8. The blind mate mechanism of claim 1 , wherein the fixed side further comprises:
coarse alignment pins;
a carriage;
a carriage retainer configured to restrict movement of the carriage;
a mounting pad comprising a hole through which the drive bolt passes when the fixed side and the removable side are mated; and
compression springs operably connected to the mounting pad and the carriage, wherein
the coarse alignment pins and the carriage retainer are operably connected to the mounting pad.
9. The blind mate mechanism of claim 1 , wherein the one or more first connectors or the one or more second connectors comprise female electrical connectors, the female electrical connectors comprising:
electrical sockets configured to carry electrical signals and/or power;
wires corresponding to the electrical sockets; and
pins that facilitate connector alignment in concert with corresponding holes in a male connector.
10. The blind mate mechanism of claim 9 , wherein
the fixed side further comprises a carriage, and
the fixed side provides lateral float for the one or more second connectors.
11. The blind mate mechanism of claim 1 , wherein the fixed side further comprises:
one or more dust/debris gates for the one or more first connectors, wherein
the one or more first connectors are male connectors comprising holes that facilitate connector alignment in concert with corresponding pins in a female connector.
12. The apparatus of claim 1 , further comprising:
one or more dust/debris gates for the one or more connectors, wherein
the one or more connectors are male connectors comprising holes that facilitate connector alignment in concert with corresponding pins in a female connector.
13. A blind mate mechanism, comprising:
a removable side, comprising:
a drive bolt, and
one or more first connectors; and
a fixed side operably connected to a device to be serviced, the fixed side comprising:
a threaded receiving interface configured to receive the drive bolt, and
one or more second connectors configured to connect with the one or more first connectors, wherein
the removable side is configured to be mated with the fixed side and de-mated with the fixed side, and
the fixed side and the removable side are configured to facilitate mechanical and structural connections, transfer of fluids, transfer of communications signals, transfer of power, or any combination thereof, between the fixed side and the removable side via the one or more first connectors and the one or more second connectors when the fixed side and the removable side are mated; wherein
the removable side further comprises a drive bolt housing that houses the drive bolt, and
the drive bolt further comprises:
a retainer configured to retain the drive bolt within the drive bolt housing,
a stopping projection configured to contact a narrowing portion of the drive bolt housing, limiting how far the drive bolt can extend, and
a spring located between the stopping projection and the narrowing part of the drive bolt housing, the spring biasing the drive bolt such that the drive bolt rests on the retainer until the removable side and the fixed side are to be mated.
14. An apparatus, comprising:
a threaded receiving interface configured to receive a drive bolt;
one or more connectors;
a carriage comprising a threaded receiving interface configured to receive the drive bolt; and
connector over-travel protectors configured to prevent the one or more connectors from overextension or overcompression; and
a carriage retainer, wherein the carriage comprises cylinders surrounding needle roller bearings mounted with pins, the cylinders configured to allow the carriage to roll up and down along the carriage retainer.
15. The apparatus of claim 14 , further comprising:
coarse alignment pins;
a carriage retainer configured to restrict movement of the carriage;
a mounting pad; and
compression springs operably connected to the mounting pad and the carriage, wherein
the coarse alignment pins and the carriage retainer are operably connected to the mounting pad.
16. The apparatus of claim 14 , wherein the apparatus provides lateral float for the one or more connectors.
17. The apparatus of claim 14 , wherein the one or more connectors comprise female electrical connectors, the female electrical connectors comprising:
electrical sockets configured to carry electrical signals and/or power;
wires corresponding to the electrical sockets; and
pins that facilitate connector alignment in concert with corresponding holes in a male connector.
