Hardline coaxial connector with a locking ferrule
View Patent ↗A hardline coaxial cable connector is disclosed. The coaxial cable connector comprises an integral locking feature formed in one or both of a body and a ferrule. The integral locking feature is monolithic with at least one of the body and the ferrule. The integral locking feature may comprise cogs part of and monolithic with the body, and slots, flats, pegs or fins part of and monolithic with the ferrule. In this way, cogs engaging with the slots, the flats, the pegs, or the fins act to lock the ferrule in stable position, and, thereby, retain the cable in a stable, non-rotatable position in the connector.
1. A coaxial cable connector for coupling an end of a coaxial cable to a terminal, the coaxial cable comprising an inner conductor, a dielectric surrounding the inner conductor, an outer conductor surrounding the dielectric, and a jacket surrounding the outer conductor, the coaxial cable connector comprising:
a body; and
a ferrule comprising a slotted ferrule body portion comprising internal annular ridges arranged to receive spiral grooves of the outer conductor, wherein the body and the ferrule form an integral locking feature, and wherein the integral locking feature locks the ferrule in a stable position, and retains a cable in a stable, non-rotatable position in the connector when the cable is inserted in the connector and the connector is tightened.
2. The coaxial cable connector of claim 1 , wherein the integral locking feature is monolithic with at least one of the body and the ferrule.
3. The coaxial cable connector of claim 1 , wherein the integral locking feature comprises at least one cog which is part of and monolithic with the body.
4. The coaxial cable connector of claim 3 , wherein the at least one cog extends axially toward the ferrule.
5. The coaxial cable connector of claim 3 , wherein the at least one cog comprises a plurality of cogs.
6. The coaxial cable connector of claim 1 , wherein the integral locking feature comprises at least one slot formed in the ferrule.
7. The coaxial cable connector of claim 6 , wherein the at least one slot is formed in a raised annular portion in the ferrule.
8. The coaxial cable connector of claim 6 , wherein the at least one slot comprises a plurality of slots.
9. The coaxial cable connector of claim 6 , wherein at least one cog in the body is adapted to engage with the at least one slot when the connector is tightened by positioning in the at least one slot.
10. The coaxial cable connector of claim 1 , wherein the integral locking feature comprises at least one peg formed in the ferrule and extending radially outwardly.
11. The coaxial cable connector of claim 10 , wherein the at least one peg comprises a plurality of pegs.
12. The coaxial cable connector of claim 11 , wherein at least one cog in the body is adapted to engage with the plurality of pegs when the connector is tightened by positioning between adjacent pegs of the plurality of pegs.
13. The coaxial cable connector of claim 1 , wherein the integral locking feature comprises at least one flat formed in the ferrule.
14. The coaxial cable connector of claim 13 , wherein the at least one flat is formed in a raised annular portion in the ferrule.
15. The coaxial cable connector of claim 13 , wherein the at least one flat comprises a plurality of flats.
16. The coaxial cable connector of claim 13 , wherein at least one cog in the body is adapted to engage with the at least one flat when the connector is tightened by positioning at the at least one flat.
17. The coaxial cable connector of claim 1 , further comprising a back nut defining a central passage, wherein at least a portion of the body and at least a portion of the ferrule are contained within the central passage.
