Abstract

Presented herein are removable pull tabs that are configured to be detachably coupled to pluggable modules in a manner that facilitates removal of the pull tabs from the module without disassembling the modules. In particular, a removable pull tab may comprise a handle and first and second substantially parallel attachment arms extending from the handle. The first and second attachment arms comprise first and second attachment mechanisms, respectively, disposed at a distal end of the respective attachment arm. The first and second attachment mechanisms are configured to detachably couple to first and second apertures, respectively, of a pluggable module.

First claim

What is claimed is:

1. A pull tab comprising:
a handle;
a first attachment arm extending from the handle;
a second attachment arm extending from the handle substantially parallel to the first attachment arm;
a first attachment mechanism disposed at a distal end of the first attachment arm; and
a second attachment mechanism disposed at a distal end of the second attachment arm, wherein the first and second attachment mechanisms are configured to detachably couple to a corresponding first and second aperture, respectively, of a pluggable module, wherein the first and second attachment mechanisms each include one or more openings, wherein a portion of the first attachment arm passes through the one or more openings of the first attachment mechanism, and wherein a portion of the second attachment arm passes through the one or more openings of the second attachment mechanism.

2. The pull tab of claim 1 , wherein the first and second attachment mechanisms each comprise a hook that is configured to engage with the corresponding first and second apertures in a slide of the pluggable module to detachably couple the pull tab to the pluggable module.

3. The pull tab of claim 2 , wherein the hooks of the first and second attachment mechanisms snap-fit into the corresponding first and second apertures.

4. The pull tab of claim 3 , wherein the pull tab is detached from the pluggable module by depressing the hooks of the first and second attachment mechanisms to disengage the hooks from the corresponding first and second apertures.

5. The pull tab of claim 1 , wherein the first attachment arm and the second attachment arm are comprised of a flexible material.

6. The pull tab of claim 5 , wherein the flexible material comprises a thermoplastic vulcanizate.

7. The pull tab of claim 1 , wherein the first attachment mechanism and the second attachment mechanism are each comprised of a metal selected from a group of: beryllium copper, and stainless steel.

8. The pull tab of claim 1 , wherein applying a force to place the first attachment arm and the second attachment arm in compression detachably couples the pull tab to the pluggable module.

9. The pull tab of claim 1 , wherein the first attachment mechanism and the second attachment mechanism are each comprised of a rigid material.

10. A method of removing a pull tab from a pluggable module, the method comprising:
providing a pull tab that is detachably coupled to a pluggable module, wherein the pull tab comprises a handle, a first attachment arm extending from the handle, a second attachment arm extending from the handle substantially parallel to the first attachment arm, a first attachment mechanism disposed at a distal end of the first attachment arm, and a second attachment mechanism disposed at a distal end of the second attachment arm, wherein the first and second attachment mechanisms are detachably coupled to a corresponding first and second aperture, respectively, of a pluggable module, wherein the first and second attachment mechanisms each include one or more openings, wherein a portion of the first attachment arm passes through the one or more openings of the first attachment mechanism, and wherein a portion of the second attachment arm passes through the one or more openings of the second attachment mechanism;
applying a first force to disengage the first attachment mechanism from the first aperture and applying a second force to disengage the second attachment mechanism from the second aperture; and
while the first force and the second force are applied, applying a third force to the pull tab to place the first attachment arm and the second attachment arm in tension, wherein applying the third force causes the pull tab to detach from the pluggable module.

11. The method of claim 10 , wherein the first attachment mechanism comprises a first hook and the second attachment mechanisms comprises a second hook, and wherein the first force is applied to the first hook to disengage the first attachment mechanism and the second force is applied to the second hook to disengage the second attachment mechanism.

12. The method of claim 10 , wherein the first force and the second force are each applied using a removal tool to apply pressure to external portions of the first attachment mechanism and the second attachment mechanism.

13. The method of claim 10 , wherein the first force is applied by inserting a first removal tool between the first attachment arm and the pluggable module, and wherein the second force is applied by inserting a second removal tool between the second attachment arm and the pluggable module.

14. The method of claim 10 , wherein the first force and the second force are each applied using a removal tool to apply pressure to portions of the first attachment arm and the second attachment arm, and wherein the first force and the second force are transmitted through a material of the first attachment arm and the second attachment arm to apply force to external portions of the first attachment mechanism and the second attachment mechanism.

15. A pull tab comprising:
a handle;
a first attachment arm extending from the handle;
a second attachment arm extending from the handle substantially parallel to the first attachment arm;
a first cavity disposed at a distal end of the first attachment arm; and
a second cavity disposed at a distal end of the second attachment arm,
wherein the first cavity and the second cavity are adapted to mate with a corresponding first slide arm and second slide arm of a slide of a pluggable module, and wherein the pull tab is attachable to the pluggable module by inserting the first slide arm into the first cavity and inserting the second slide arm into the second cavity, wherein the first attachment arm and the second attachment arm are comprised of a flexible material, and wherein the flexible material is penetrable by one or more barbs of the first slide arm and the second slide arm that penetrate into the flexible material when the first cavity and the second cavity are mated with the first slide arm and second slide arm.

16. The pull tab of claim 15 , wherein the flexible material comprises a thermoplastic vulcanizate.

17. The pull tab of claim 15 , wherein the pull tab locks onto a slide of the pluggable module when the first slide arm is inserted into the first cavity and the second slide arm is inserted into the second cavity.

18. The pull tab of claim 15 , further comprising a knob disposed in each of the first cavity and the second cavity, wherein each knob is configured to mate with a corresponding first and second aperture, respectively, of the first slide arm and the second slide arm.

19. The pull tab of claim 15 , wherein the first and second cavities are disposed in a corresponding pair of extensions extending substantially orthogonal from the distal ends of the first and second attachment arms.

20. The pull tab of claim 15 , wherein the pull tab is destructively removable from the pluggable module by tearing the flexible material of the first attachment arm and the second attachment arm.
