Abstract

Connectors with locking mechanisms and associated systems and methods are disclosed herein. A connector in accordance with an embodiment of the present technology, for example, can include a connector body having an inner surface defining a first bore and a collet movably received in the first bore. The collet can have an inner surface defining a second bore that is configured to receive a mating second connector. The connector can further include a locking mechanism that is operably coupled to the connector body and has an open position and a closed position. The collet is configured to operably engage the second connector when the locking mechanism is in the closed position and release the second connector when the locking mechanism in the open position.

10. The first connector of claim 1 wherein:

the first connector is a male F-type connector;

at least one of the inner surface of the connector body and the inner surface of the collet have a smaller diameter at the distal end portion than at the proximal end portion;

at least a portion of the inner surface of the collet includes internal threads; and

the locking mechanism includes a first latch pivotally attached to the connector body and a second latch spaced circumferentially apart from the first latch and pivotally attached to the connector body, the first and second latches having a driving portion configured to slide the collet relative to the connector body toward a distal end portion as the locking mechanism moves from the open position toward the closed position.

11. The first connector of claim 1 wherein the inner surface of the collet is unthreaded.

12. The first connector of claim 1, wherein:

the connector body includes a sidewall with an opening in communication with the first bore;

the locking mechanism is positioned on the sidewall of the connector body and includes a driving portion, wherein the driving portion is configured to operably extend through the opening to press against an end portion of the collet to slide the collet forward relative to the connector body toward the second connector as the locking mechanism moves from the open position to the closed position; and

the collet is configured to radially contract as the collet slides forward relative to the connector body.

13. The first connector of claim 1 wherein:

the first connector is a male coaxial cable connector; and

the collet is sized to engage an outermost surface of a female coaxial cable connector as the locking mechanism moves from the open position to the closed position.

14. The first connector of claim 1 wherein the locking mechanism includes at least one latch pivotally attached to the connector body, and wherein the latch is configured to pivot radially inward toward the connector body as the locking mechanism moves to the closed position and drive the collet forward relative toward a distal end portion of the connector body.

15. A first connector for operably coupling a cable to a mating second connector, the first connector comprising:

a connector body having an inner surface defining a first bore;

a collet movably received in the first bore, the collet having an inner surface defining a second bore configured to receive the second connector; and

a locking mechanism operably coupled to the connector body and having an open position and a closed position, wherein the collet is configured to operably engage the second connector when the locking mechanism is in the closed position and release the second connector when the locking mechanism is in the open position, and wherein the locking mechanism includes at least one latch pivotally coupled to the connector body.

16. The first connector of claim 15 wherein the latch includes a driving portion configured to bear against a proximal end portion of the collet and move the collet relative to the connector body as the latch moves to the closed position.

17. The first connector of claim 15 wherein the latch includes a locking portion having an engagement feature configured to engage a corresponding portion of the connector body when the latch is in the closed position.

18. The first connector of claim 17 wherein the engagement feature includes a hook configured to engage an edge of a proximal end portion of the connector body when the latch is in the closed position.

19. A connector, comprising:

a collet having an inner surface defining a bore, the bore being configured to receive a mating connector;

a locking mechanism operably coupled to the collet, the locking mechanism having an open position and a closed position, wherein the locking mechanism is configured to drive the collet into compressible engagement with the mating connector as the locking mechanism moves from an open position toward the closed position, and wherein the locking mechanism is configured to release the collet from the mating connector as the locking mechanism moves away from the closed position toward the open position; and

a connector body having a tapered bore that slidably receives the collet.

20. The connector of claim 19 wherein the locking mechanism includes at least one latch having a driving portion that moves the collet relative to the connector body as the latch moves to the closed position.
