Connector coupling assembly

1 . A coupler comprising:

a first connector having a first end, a second end opposite the first end, a central axis extending through at least the first end and the second end, a body disposed between the first end and the second end, and a first valve disposed proximate the second end;

a second connector having a threaded mating portion, a connecting portion opposite the mating portion, a second valve disposed within the mating portion, and a pin disposed at least partially within the mating portion; and

a collar having:

a releasing portion detachably coupled to the first connector and comprising a first portion, a second portion, and a slot disposed therebetween, the first and second portions being separated by the first connector when the releasing portion is coupled to the first connector; and

a body detachably coupled to the mating portion of the second connector,

wherein the collar is configured to couple the first connector to the second connector such that a portion of the first connector is disposed between the first portion and the second portion of the releasing portion and at least the second end of the first connector is disposed within the second connector,

wherein the first connector is configured to decouple from the collar and the second connector in response to a pullout force exceeding a predetermined threshold force,

wherein the first portion and the second portion are configured to draw together when the first connector decouples from the collar,

wherein the first connector is prevented from re-coupling to the second connector and the collar when the first portion and the second portion are drawn together.

2 . A coupler comprising:

a first connector having a first end, a second end opposite the first end, and a first valve disposed between the first end and the second end;

a second connector having a mating portion, a connecting portion opposite the mating portion, and a second valve disposed at least partially within the mating portion; and

a collar having:

a body detachably coupled to the mating portion of the second connector; and

a releasing portion disposed opposite the body, comprising a slot, and configured to flex radially inward to close the slot,

wherein, when the slot is open, the slot receives at least a portion of the first connector to detachably couple the first connector to the collar and the second connector such that the second end of the first connector is disposed within the second connector,

wherein the releasing portion flexes radially inward to close the slot when the first connector is decoupled from the collar and the second connector such that the first connector is prevented from re-coupling to the collar.

3 . The coupler of claim 2 , wherein the first connector is configured to decouple from the collar in response to a pullout force exceeding a predetermined threshold force.

4 . The coupler of claim 3 , wherein the pullout force is a force applied to the first connector along a central axis of the first connector.

5 . The coupler of claim 4 , wherein the central axis extends through the first connector, the collar, and the second connector when the first connector is coupled to the collar and the collar is coupled to the second connector.

6 . The coupler of claim 3 , wherein the first connector is configured to remain coupled to the collar when the pullout force does not exceed the predetermined threshold force.

7 . The coupler of claim 2 , wherein the slot at least partially longitudinally extends along the collar.

8 . The coupler of claim 2 , wherein the slot is configured to allow the releasing portion to radially expand outwards when the slot is open.

9 . The coupler of claim 2 , wherein the first valve is prevented from contacting the second valve when the releasing portion is flexed radially inwards.

10 . The coupler of claim 2 , wherein the first connector includes a body having an interior space, the interior space housing the first valve.

11 . The coupler of claim 10 , wherein the first connector includes a biasing element disposed within the interior space, the biasing element coupled to the first valve.

12 . The coupler of claim 2 , wherein the first connector includes a guide and the collar includes a channel sized and shaped to receive the guide to prevent rotational movement of the first connector relative to the collar when the guide is disposed within the channel.

13 . The coupler of claim 12 , wherein the guide extends from an external surface of the first connector and the first connector includes a wedge extending from the external surface opposite the guide, the wedge sized and shaped to be received by the slot.

14 . The coupler of claim 2 , wherein the first valve is disposed proximate the second valve when the first connector is coupled to the collar.

15 . The coupler of claim 2 , wherein the second end of the first connector is disposed within the body when the first connector is coupled to the collar.

16 . The coupler of claim 2 , wherein the first connector includes a wedge having a ramp and the slot is sized and shaped to receive the wedge such that the wedge is at least partially disposed within the slot when the first connector is coupled to the collar.

17 . The coupler of claim 2 , wherein the first connector includes a stopper configured to prevent axial movement of the collar to an area proximate the first end.

18 . The coupler of claim 2 , wherein the second connector includes a pin disposed between the mating portion and the connecting portion, and the pin at least partially extends into the first valve when the first connector is coupled to the collar and the collar is coupled to second connector.

19 . A coupler comprising:

a first connector having a first end, a second end opposite the first end, a central axis extending through at least the first end and the second end, a body disposed between the first end and the second end, and a first valve disposed proximate the second end, the body having an interior space housing the first valve and a biasing element coupled to the first valve;

a second connector having a threaded mating portion, a connecting portion opposite the mating portion, a second valve disposed within the mating portion, and a pin disposed at least partially within the mating portion; and

a collar having a releasing portion detachably coupled to the first connector and a body threadably coupled to the mating portion of the second connector, the releasing portion having a slot that opens and longitudinally extends through the releasing portion and receives at least a portion of the first connector when the releasing portion is coupled to the first connector,

wherein the collar is configured to couple the first connector to the second connector such that at least the second end of the first connector is disposed within the second connector,

wherein the first connector is configured to decouple from the collar and the second connector in response to a pullout force exceeding a predetermined threshold force,

wherein the slot is configured to close when the first connector decouples from the collar,

wherein the first connector is prevented from re-coupling to the second connector and the collar when the slot is closed,

wherein the central axis extends through the first connector, the collar, and the second connector when the collar is coupled to the first connector and the second connector.
