Abstract

A telecommunications and networking equipment housing including: a body defining a slot adapted to receive a shelf; and an adjustable key component coupled to the body and defining a channel adapted to receive a fixed key component coupled to the shelf, wherein the channel is movable between a first location and a second location along a front edge of the slot. The fixed key component coupled to the shelf is aligned with the channel defined by the adjustable key component in either the first location or the second location. The adjustable key component is translatable along the front edge of the slot such that the channel is movable between the first location and the second location.

First claim

The invention claimed is:

1. A telecommunications and networking equipment housing comprising:
a body defining a slot adapted to receive a shelf through a front edge of the slot; and
an adjustable key component coupled to the body at the front edge of the slot and defining a channel adapted to receive a fixed key component coupled to the shelf, wherein the channel is movable between a first location and a second location along the front edge of the slot.

2. The housing of claim 1 , wherein the fixed key component coupled to the shelf is aligned with the channel defined by the adjustable key component in either the first location or the second location.

3. The housing of claim 1 , wherein the adjustable key component is translatable along the front edge of the slot such that the channel is movable between the first location and the second location.

4. The housing of claim 1 , wherein the adjustable key component is rotatable with respect to the front edge of the slot such that the channel intended to receive the fixed key component is movable between the first location and the second location via rotation of the adjustable key component.

5. The housing of claim 1 , wherein the adjustable key component comprises a first key component that is disposable in a recess formed in the front edge of the slot and a second key component that is disposable in the recess formed in the front edge of the slot, such that the channel intended to receive the fixed key component is movable between the first location and the second location by switching between the first key component and a first channel defined by the first key component being coupled to the body and the second key component and a second channel defined by the second key component being coupled to the body.

6. The housing of claim 1 , wherein the channel comprises a recess with a stop located at a back portion thereof, wherein the recess is adapted to receive and retain a front fixed key disposed at a front portion of the shelf when the shelf is fully inserted into the slot.

7. The housing of claim 1 , wherein the channel comprises a groove, wherein the groove is adapted to receive and pass through a back fixed key disposed at a back portion of the shelf when the shelf is partially inserted into the slot and receive and retain a front fixed key disposed at a front portion of the shelf when the shelf is fully inserted into the slot.

8. The housing of claim 1 , wherein:
the body defines an additional slot disposed adjacent to the slot adapted to receive an additional shelf adjacent to the shelf; and
the adjustable key component defines an additional channel adjacent to the channel adapted to receive an additional fixed key component coupled to the additional shelf, wherein the additional channel is movable between a first location and a second location along a front edge of the additional slot as the channel is movable between the first location and the second location along the front edge of the slot.

9. The housing of claim 1 , further comprising a backplane disposed at a back portion of the housing and adapted to make an electrical connection with a connector disposed at a back portion of the shelf when the shelf is fully inserted into the slot.

10. A telecommunications and networking equipment assembly comprising:
a shelf comprising a fixed key component coupled to an external surface thereof; and
a housing comprising:
a body defining a slot adapted to receive the shelf through a front edge of the slot; and
an adjustable key component coupled to the body at the front edge of the slot and defining a channel adapted to receive the fixed key component coupled to the shelf, wherein the channel is movable between a first location and a second location along the front edge of the slot.

11. The assembly of claim 10 , wherein the fixed key component coupled to the shelf is aligned with the channel defined by the adjustable key component in either the first location or the second location.

12. The assembly of claim 10 , wherein the adjustable key component is translatable along the front edge of the slot such that the channel is movable between the first location and the second location.

13. The assembly of claim 10 , wherein the adjustable key component is rotatable with respect to the front edge of the slot such that the channel intended to receive the fixed key component is movable between the first location and the second location via rotation of the adjustable key component.

14. The assembly of claim 10 , wherein the adjustable key component comprises a first key component that is disposable in a recess formed in the front edge of the slot and a second key component that is disposable in the recess formed in the front edge of the slot, such that the channel intended to receive the fixed key component is movable between the first location and the second location by switching between the first key component and a first channel defined by the first key component being coupled to the body and the second key component and a second channel defined by the second key component being coupled to the body.

15. The assembly of claim 10 , wherein the channel comprises a recess with a stop located at a back portion thereof, wherein the recess is adapted to receive and retain a front fixed key disposed at a front portion of the shelf when the shelf is fully inserted into the slot.

16. The assembly of claim 10 , wherein the channel comprises a groove, wherein the groove is adapted to receive and pass through a back fixed key disposed at a back portion of the shelf when the shelf is partially inserted into the slot and receive and retain a front fixed key disposed at a front portion of the shelf when the shelf is fully inserted into the slot.

17. The assembly of claim 10 , further comprising an additional shelf comprising an additional fixed key component coupled to an external surface thereof, wherein:
the body defines an additional slot disposed adjacent to the slot adapted to receive the additional shelf adjacent to the shelf; and
the adjustable key component defines an additional channel adjacent to the channel adapted to receive the additional fixed key component coupled to the additional shelf, wherein the additional channel is movable between a first location and a second location along a front edge of the additional slot as the channel is movable between the first location and the second location along the front edge of the slot.

18. The assembly of claim 10 , the housing further comprising a backplane disposed at a back portion thereof and adapted to make an electrical connection with a connector disposed at a back portion of the shelf when the shelf is fully inserted into the slot.

19. A telecommunications and networking equipment method comprising:
given a housing comprising a body defining a slot adapted to receive a shelf through a front edge of the slot and an adjustable key component coupled to the body at the front edge of the slot and defining a channel adapted to receive a fixed key component coupled to the shelf, wherein the channel is movable between a first location and a second location along the front edge of the slot, moving the channel between the first location and the second location.

20. The method of claim 19 , wherein the fixed key component coupled to the shelf is aligned with the channel defined by the adjustable key component in the second location, the method further comprising inserting the shelf into the slot with the fixed key component coupled to the s
