Abstract

A buildout system generally comprising a buildout base and a buildout cap. The base includes lateral sides that extend beyond the top and bottom sides of the base to form side flanges, and upper and lower panel flanges that extend upwardly and downwardly from the side flanges. In addition, the base includes a plurality of gussets that extend forwardly from the lateral sides of the base. The cap includes upper and lower latch tabs that extend outwardly from the top and bottom sides of the cap and a plurality of recesses that are adapted to receive the gussets of the base. In one aspect of the invention, the base further includes vertical flanges and the cap includes vertical recesses adapted to receive the vertical flanges of the base when the cap is releasably connected to the base.

Claims

1. Optical fiber buildout apparatus that is resistant to side loads, comprising:

a buildout base including a top side, a bottom side, a front side, a rear side, opposed lateral sides, and a plurality of gussets that extend forwardly from said lateral sides; and

a buildout cap including a top side, a bottom side, a front side, a rear side, opposed lateral sides, and a plurality of gusset recesses formed at the junction of said top and bottom sides with said lateral sides, said recesses being sized and shaped to receive said gussets when said cap is releasably connected to said base;

wherein when said cap is releasably connected to said base, said gusset recesses of said cap receive said gussets of said base to increase the surface contact area between said cap and base when said cap is subjected to side loads.

2. The optical fiber buildout apparatus of claim 1, wherein said lateral sides of said base extend beyond said top and bottom sides of said base to form side flanges and wherein said cap further includes upper and lower latch tabs that extend outwardly from said top and bottom sides of said cap, respectively, said latch tabs being adapted to fit closely between said side flanges of said base.

3. The optical fiber buildout apparatus of claim 2, wherein said base further includes upper and lower panel flanges that extend upwardly and downwardly from said opposed lateral sides of said base, respectively, each of said panel flanges having a central notch defined by side surfaces formed therein.

4. The optical fiber buildout apparatus of claim 3, wherein said latch tabs of said cap has a relatively wide base portion and a relatively narrow upper portion, wherein said base portions are sized and shape to fit closely between said side flanges of said base and said upper portions are sized and shaped to fit closely between said side surfaces of said central notches of said base.

5. The optical fiber buildout apparatus of claim 2, wherein said base further includes upper and lower latch tabs that extend upwardly from said top side and downwardly from said bottom side of said base, respectively, said latch tabs of said base being oriented to fit closely about said latch tabs of said cap.

6. The optical fiber buildout apparatus of claim 1, wherein said buildout base further includes vertical flanges and said buildout cap further includes vertical recesses adapted to receive said vertical flanges of said buildout base.

7. Optical fiber buildout apparatus that is resistant to side loads, comprising:

a buildout base including a top side, a bottom side, a front side, a rear side, opposed lateral sides, and a plurality of gussets that extend forwardly from said lateral sides, said base further including a pair of vertical flanges that extend forwardly from said front side; and

a buildout cap including a top side, a bottom side, a front side, a rear side, and opposed lateral sides, said cap further including a plurality of gusset recesses and a pair of vertical recesses formed in said lateral sides of said cap;

wherein when said cap is releasably connected to said base, said gusset recesses of said cap receive said gussets of said base and said vertical recesses of said cap receive said vertical flanges of said base to increase the surface contact area between said cap and base when said cap is subjected to side loads.

8. The optical fiber buildout apparatus of claim 7, wherein said base includes two pairs of upper and lower gussets and said vertical flanges extend from said front side of said base to the tips of said gussets and between each pair of upper and lower gussets such that said vertical flanges are substantially rectilinear and plate-shaped.

9. The optical fiber buildout apparatus of claim 7, wherein said lateral sides of said base extend beyond said top and bottom sides of said base to form side flanges and wherein said cap further includes upper and lower latch tabs that extend outwardly from said top and bottom sides of said cap, respectively, said latch tabs being adapted to fit closely between said side flanges of said base.

10. The optical fiber buildout apparatus of claim 9, wherein said base further includes upper and lower panel flanges that extend upwardly and downwardly from said opposed lateral sides of said base, respectively, each of said panel flanges having a central notch defined by side surfaces formed therein.

11. The optical fiber buildout apparatus of claim 10, wherein said latch tabs of said cap has a relatively wide base portion and a relatively narrow upper portion, wherein said base portions are sized and shape to fit closely between said side flanges of said base and said upper portions are sized and shaped to fit closely between said side surfaces of said central notches of said base.

12. The optical fiber buildout apparatus of claim 9, wherein said base further includes upper and lower latch tabs that extend upwardly from said top side and downwardly from said bottom side of said base, respectively, said latch tabs of said base being oriented to fit closely about said latch tabs of said cap.

13. A method for increasing the resistance to side loads of an optical fiber buildout system that includes a buildout base and a buildout cap, said method comprising the steps of:

forming opposed lateral sides on the base that extend beyond the top and bottom sides of the base to form side flanges;

forming, a plurality of gussets on the base that extend forwardly from the lateral sides of the base;

forming upper and lower latch tabs on the cap that extend outwardly from the top and bottom sides of the cap and that are sized, shaped, and configured to fit closely between the side flanges of the base; and

forming a plurality of recesses in the cap that are sized, shaped, and configured to receive the gussets of the base;

wherein when the cap is releasably connected to the base, the latch tabs arc positioned closely between the side flanges of the base and the gussets are received by the recesses of the cap such that an enlarged contact surface area is formed between the cap and base when side loads are applied to the cap.

14. The method of claim 13, further comprising the steps of:

forming upper and lower panel flanges on the base that extend upwardly and downwardly from the opposed lateral sides of the base, respectively, each of the panel flanges having a central notch defined by side surfaces formed therein; and

forming the latch tabs of the cap to include a relatively wide base portion and a relatively narrow upper portion, wherein the base portions are sized and shape to fit closely between the side flanges of the base and the upper portions are sized and shaped to fit closely between the side surfaces of the central notches of the base.
