Abstract
A rotary joint is disclosed. The rotary joint comprise a power transfer interface for transferring power between a first portion having a first magnetic core and a second portion having a second magnetic core and rotatable relative to the first portion. The rotary joint may also comprise a data interface for transferring data between a cable and a second cable that is rotatable relative to the first cable.
Claims20
A rotary joint for data and power transfer comprising:
- a data interface for transferring data between a first cable and a second cable that is rotatable relative to the first cable;
- a power transfer interface for transferring power between a first portion having a first magnetic core and a second portion having a second magnetic core and rotatable relative to the first portion;
- and
- a lock member coupled to the second cable and extending into one or more recesses in the second magnetic core, wherein rotation of the second cable causes the locking member to engage the second magnetic core to rotate the second portion relative to the first portion.

A rotary joint comprising:
- a power transfer interface for transferring power between a first portion having a first magnetic core and a second portion having a second magnetic core, wherein the second magnetic core is rotatable relative to the first portion;
- and
- a fiber optic interface for transferring data between a first fiber optic portion and a second fiber optic portion that is rotatable relative to the first fiber optic portion, the fiber optic interface comprising a biasing mechanism and a lock member, wherein the biasing mechanism is configured to bias at least one of the first fiber optic portion or the second fiber optic portion toward the other of the first fiber optic portion or the second fiber optic portion, wherein the lock member is coupled to the second fiber optic portion and extends into one or more recesses in the second magnetic core, wherein the locking member is configured to engage the second magnetic core to rotate the second portion relative to the first portion.
A radar system comprising:
- an antenna mounting apparatus;
- an antenna rotatably coupled to the mounting apparatus by at least one rotary joint, the rotary joint comprising:
- a data interface for transferring data between a first cable and a second cable that is rotatable relative to the first cable;
- and
- a power transfer interface for transferring power between a first magnetic core and a second magnetic core that is rotatable relative to the first magnetic core and spaced apart from the first magnetic core.
