Abstract

A connector housing apparatus for allowing field engineers or technicians to run cable point to point, and to protect the connection in an environmentally sealed, crush resistant housing is provided. The connector housing apparatus includes a connector housing body, two sealing boots, two sealing elements, two seal nuts, a fiber optic adapter, a fiber optic adapter insert that holds the fiber optic adapter and two fiber optic pigtails connected to two fiber optic cables. Each boot has two seal points. The first seal is between the fiber optic cable, the sealing element, the seal nut and the tapered portion of the sealing boot. The second seal is between the snap finger on the sealing boot and the receiving catch on the connector housing body.

First claim

The invention claimed is:

1. A connector housing apparatus comprising:
a connector housing body;
a first sealing boot;
a second sealing boot;
a first seal nut;
a second seal nut;
a first sealing element;
a second sealing element;
a fiber optic adapter configured to connect to a first fiber optic pigtail and a second fiber optic pigtail; and
a fiber optic adapter insert that holds the fiber optic adapter, wherein,
the first sealing boot and the second sealing boot are connected to the connector housing body at opposite ends of the connector housing body,
the first seal nut is connected to the first seal boot and the second seal nut is connected to the second boot,
the connector housing body is configured to surround an entirety of the fiber optic adapter therein, and
the first and second sealing elements seal and interpose respective exteriors of the first and second sealing boots and respective ones of the first and second seal nuts and are directly attached thereto.

2. The connector housing apparatus of claim 1 , wherein,
a first fiber optic cable connected to the first fiber optic pigtail, the first sealing element, the first seal nut and a tapered section of the first sealing boot form a first seal, and
a second fiber optic cable connected to the second fiber optic pigtail, the second sealing element, the second seal nut and a tapered section of the second sealing boot form a second seal.

3. The connector housing apparatus of claim 2 , wherein,
the connector housing body comprises a first snap finger and a second snap finger at its opposite ends,
the first sealing boot comprises a receiving catch,
the second sealing boot comprises a receiving catch,
the first snap finger of the connecter housing body and the receiving catch of the first sealing boot are connected to form a third seal; and
the second snap finger of the connecter housing body and the receiving catch of the second sealing boot are connected to form a fourth seal.

4. The connector housing apparatus of claim 3 , wherein the connector housing body further comprises a snap finger release tab to allow for disengaging of the sealing boot from the connector housing body.

5. The connector housing apparatus of claim 2 , wherein the first sealing element and the second sealing element are at least one of elastomer seal grommet, b-sealing tape, closed cell foam tape, compressible elastomer and molded grommet.

6. The connector housing apparatus of claim 2 , wherein,
the first seal boot and the second seal boot further comprise a seal nut retention groove, a sealing element compression dam to hold the first sealing element and the second sealing element, and a ram quarter turn twist lock feature,
the first seal nut is connected to the first seal boot using the seal nut retention groove of the first seal boot,
the second seal nut is connected to the second seal boot using the seal nut retention groove of the second seal boot, and
the first seal nut and the second seal nut use the ram quarter turn twist lock feature for seal nut compression lock.

7. The connector housing apparatus of claim 1 , wherein the connector housing body comprises an enclosure mounting shoulder and external threads on one end allowing for installation of the connector housing apparatus on an enclosure.

8. The connector housing apparatus of claim 7 , further comprising a locking nut,
wherein, the connector housing apparatus can be mounted onto an exterior surface of the enclosure using the locking nut.

9. The connector housing apparatus of claim 7 , wherein the connector housing body shoulder and the connector housing body are sized to fit National Pipe Taper (NPT) port sizes.

10. The connector housing apparatus of claim 1 , wherein the fiber optic adapter insert comprises a receiving catch which snaps into a retention tab on the inner surface of the connector housing body.

11. The connector housing apparatus of claim 1 , wherein,
the fiber optic adapter insert comprises a cutout which can be modified to accommodate a variety of fiber optic adapters, and
the fiber optic adapter insert cutout can be modified to accommodate one or more adapters.

12. The connector housing apparatus of claim 11 , wherein the variety of fiber optic adapters is one of a simplex FC, simplex ST, simplex LC, simplex SC, simplex MU, duplex LC, duplex MU, and MPO/MTP adapter.

13. The connector housing apparatus of claim 1 , wherein,
the first fiber optic pigtail comprises a fiber optic connector body and a fiber optic connector boot, the second fiber optic pigtail comprises a fiber optic connector body and a fiber optic connector boot, and
the fiber optic connector body of the first fiber optic pigtail and the fiber optic connector body of the second fiber optic pigtail are connected with the fiber optic adapter.

14. The connector housing apparatus of claim 1 , further comprising:
a first O-Ring; and a second O-Ring, wherein,
the connector housing body comprises a first groove which holds the first O-Ring and a second groove which holds the second O-Ring, when the first sealing boot is connected to the connector housing body, the first sealing boot, the first O-Ring and the connector housing body form a seal, and
when the second sealing boot is connected to the connector housing body, the second sealing boot, the second O-Ring and the connector housing body form a seal.

15. The connector housing apparatus of claim 1 , further comprising:
a first O-Ring; and a second O-Ring, wherein,
the first sealing boot comprises a first groove on its interior surface which holds the first O-Ring, the second sealing boot comprises a second groove on its interior surface which holds the second O-Ring, when the first sealing boot is connected to the connector housing body, the first sealing boot, the first O-Ring and the connector housing body form a seal, and when the second sealing boot is connected to the connector housing body, the second sealing boot, the second O-Ring and the connector housing body form a seal.

16. The connector housing apparatus of claim 1 , wherein the connector housing apparatus can be disassembled and reassembled.

17. The connector housing apparatus of claim 1 , wherein the connector housing apparatus can be mounted to a bulkhead in at least one of a single and gang mounted manner.

18. The connector housing apparatus of claim 1 , wherein the connector housing apparatus can be installed on one of an enclosure, closure, terminal and junction box.
