Abstract

Attachment mechanisms configured to be employed to attach a rear housing section to a fiber optic housing, and related assemblies and methods are disclosed. The rear housing section and the fiber optic housing may be part of fiber optic equipment configured to support fiber optic connections of a fiber optic network. The attachment mechanism is configured to be attached and extend from the rear housing section of the fiber optic housing while maintaining the same installed U space of the housing. The attachment mechanism may include a spring plunger which may releasably maintain the rear housing section in a position to allow fasteners to removably attach the rear housing section to the fiber optic housing. In this manner, the rear housing section may be attached to and removed from the fiber optic housing in an efficient manner to minimize downtime for the fiber optic network.

Claims

1. A fiber optic equipment assembly, comprising:

a rear housing section for a fiber optic housing; and

an attachment mechanism extending from the rear housing section, the attachment mechanism configured to removably attach the rear housing section to the fiber optic housing, wherein the attachment mechanism comprises at least one spring plunger configured to releasably maintain the rear housing section in a position to allow fasteners to removably attach the rear housing section to the fiber optic housing, and wherein the housing maintains an installed U-space the housing occupied prior to the rear housing section being removably attached to the housing.

2. The fiber optic equipment assembly of claim 1, wherein the attachment mechanism comprises a flange, and the spring plunger extends through the flange.

3. The fiber optic equipment assembly of claim 2, wherein the flange comprises fastener holes for receiving the fasteners.

4. The fiber optic equipment assembly of claim 1, wherein the attachment mechanism is inserted inside a side wall of the housing.

5. The fiber optic equipment assembly of claim 1, wherein the rear housing section comprises a substantially flat, rectangular plate.

6. The fiber optic equipment assembly of claim 5, wherein the plate comprises two major sides and two minor sides.

7. The fiber optic equipment assembly of claim 6, wherein the attachment mechanism attaches to and extends from opposite corners of one of the major sides.

8. The fiber optic equipment assembly of claim 5, further comprising at least one trunk plate including strain relief receivers positioned on the substantially flat, rectangular plate.

9. The fiber optic equipment assembly of claim 8, wherein the strain relief receivers are configured to receive fasteners, the fasteners being one or more of tie wraps and cable clamps, and the fasteners are used to attach fiber optic cables to the trunk plate.

10. The fiber optic equipment assembly of claim 1, wherein the rear housing section is an extension tray.

11. The fiber optic equipment assembly of claim 1, wherein the rear housing section is a 2U-sized rear cover.

12. A method of adding a housing section to a fiber optic housing, comprising:

providing a removable rear housing section including an attachment mechanism, the attachment mechanism comprising a flange with fastener holes and a spring plunger;

fitting the rear housing section to the fiber optic housing by inserting the flange inside a side wall of the fiber optic housing;

retracting the spring plunger as the flange moves inside of the side wall; and

extending the spring plunger into a spring plunger hole when the flange reaches a position where the spring plunger aligns with the spring plunger hole, wherein the housing maintains an installed U-space the housing occupied prior to the rear housing section being fitted to the housing.

13. The method of claim 12, wherein a biasing force of a spring on the spring plunger extends the spring plunger into the spring plunger hole.

14. The method of claim 12, further comprising removably attaching the rear housing section to the fiber optic housing by inserting fasteners through side wall holes of the side wall of the fiber optic housing and into the fastener holes of the attachment mechanism.

15. The method of claim 14, wherein the removably attaching the rear housing section further comprises aligning the fastener holes with the side wall holes while the spring plunger releasably maintains the rear housing section in a position allowing fasteners to be inserted through the side wall holes and into the fastener holes.

16. A method of upgrading a first rear housing section attached to a fiber optic housing, comprising:

providing a first rear housing section attached to fiber optic housing by an attachment mechanism extending from the first rear housing section, the attachment mechanism comprising a flange with fastener holes and a spring plunger;

removing the first rear housing section from the fiber optic housing by removing fasteners disposed through side wall holes of a side wall of the fiber optic housing and fastener holes of a flange of the attachment mechanism;

retracting the spring plunger from a spring plunger hole of the fiber optic housing;

removing the flange of the first rear housing section from inside the side wall of the fiber optic housing; and

attaching a second rear housing section to the fiber optic housing.

17. The method of claim 16, wherein the attaching the second rear housing section comprises:

fitting the second rear housing section to the fiber optic housing by inserting a second flange of a second attachment mechanism inside the side wall of the fiber optic housing, the second attachment mechanism extends from the second rear housing section;

retracting a second spring plunger of the second rear housing section as the second flange moves inside of the side wall; and

extending the second spring plunger into the spring plunger hole when the second flange reaches a position where the second spring plunger aligns with the spring plunger hole.

18. The method of claim 17, wherein a biasing force of a spring on the second spring plunger extends the second spring plunger into the spring plunger hole.

19. The method of claim 17, further comprising removably attaching the second rear housing section to the fiber optic housing by inserting fasteners through the side wall holes and into fastener holes of the second attachment mechanism.

20. The method of claim 19, wherein the removably attaching the second rear housing section further comprises aligning the fastener holes of the second attachment mechanism with the side wall holes while the second spring plunger releasably maintains the second rear housing section in a position allowing fasteners to be inserted through the side wall holes and into the fastener holes of the second attachment mechanism.
