Abstract

A fiber optic distribution box includes a box body and detachable mounting caps to mount fiber optic connectors to the box body. The box body has a box terminal wall formed with through holes. The detachable mounting caps are disposed on the through holes and connected detachably to the box terminal wall. Each detachable mounting cap has a hollow cap body, and a mount hole formed inside the hollow cap body. The hollow cap body includes a cap bottom surface lying on the box terminal wall, and a front inclined cap surface inclined with respect to the box terminal wall. The mount hole extends through the front inclined cap surface and the cap bottom surface to communicate with a cable reception space of the box body through the respective through hole.

First claim

What is claimed is:

1. A fiber optic distribution box for connecting a fiber optic cable to a plurality of fiber optic connectors, comprising:
a box body having a box terminal wall and a surrounding box wall connected to said box terminal wall, said box terminal wall and said surrounding box wall cooperatively bounding a cable reception space, said box terminal wall being formed with a plurality of spaced-apart through holes communicating with said cable reception space, said surrounding box wall being formed with an input hole for the fiber optic cable to extend into said cable reception space; and
a plurality of detachable mounting caps disposed respectively on said through holes and connected detachably to said box terminal wall, each of said detachable mounting caps having a hollow cap body detachably mounted to said box terminal wall, and a mount hole formed inside said hollow cap body, said hollow cap body including a cap bottom surface and a front inclined cap surface, said cap bottom surface lying on said box terminal wall above a respective one of said through holes, said front inclined cap surface inclinedly extending upward from said cap bottom surface and inclined with respect to said box terminal wall, said mount hole extending through said front inclined cap surface and said cap bottom surface to communicate with said cable reception space and to mount one of the fiber optic connectors;
wherein said hollow cap body further includes a recess that is indented from said cap bottom surface and that surrounds said mount hole, and a seal ring that is received in said recess and that is disposed between said cap bottom surface and said box terminal wall to provide a seal between said cap bottom surface and said box terminal wall.

2. The fiber optic distribution box as claimed in claim 1 , wherein said hollow cap body further includes a rear inclined cap surface that inclinedly extends upward from said cap bottom surface oppositely of said front inclined cap surface and that has a top end meeting a top end of said front inclined cap surface, and two spaced apart opposite side surfaces, each of which is connected between said front and rear inclined cap surfaces.

3. The fiber optic distribution box as claimed in claim 1 , wherein said box terminal wall is flat so that said through holes lie in a same plane.

4. The fiber optic distribution box as claimed in claim 1 , wherein said hollow cap body further includes an inner surrounding surface bounding said mount hole, said inner surrounding surface having an internal thread configured for threadedly connecting one of the fiber optic connectors.

5. The fiber optic distribution box as claimed in claim 1 , wherein said mount hole of said hollow cap body has a first hole portion and a second hole portion, said first hole portion penetrating said cap bottom surface and extending upwardly away from said box terminal wall of said box body, said second hole portion connecting said first hole portion and penetrating said front inclined cap surface, said second hole portion being smaller in cross section than said first hole portion.

6. The fiber optic distribution box as claimed in claim 1 , further including a plurality of packing rings, each of which is disposed between said box terminal wall and said cap bottom surface of one of said detachable mounting caps, each of said packing rings having a ring hole aligned with said mount hole of the respective one of said detachable mounting caps and one of said through holes of said box body.

7. The fiber optic distribution box as claimed in claim 1 , wherein an inclining angle between said cap bottom surface and said front inclined cap surface ranges between 10 degrees and 60 degrees.
