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, first and second substantially parallel attachment arms extending from the handle, and a reinforcement line embedded in the handle and first and second attachment arms. 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;
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; and
a reinforcement line coupled to the first attachment mechanism and the second attachment mechanism, the reinforcement line embedded in the handle, first attachment arm, and second attachment arm.

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 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.

4. The pull tab of claim 1 , wherein the reinforcement line is configured to transmit a pulling force received at the handle directly to the first and second attachment mechanisms.

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 1 , wherein the reinforcement line extends from the first attachment mechanism through the first attachment arm, the handle, and the second attachment arm to the second attachment mechanism.

7. The pull tab of claim 1 , wherein the reinforcement line, the first attachment mechanism and the second attachment mechanism are coupled via one of: an interference fit, solder, a weld, or an adhesive.

8. The pull tab of claim 1 , 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.

9. The pull tab of claim 1 , wherein reinforcement line is composed of one of: a metallic or non-metallic wire, a cord, or a strip.

10. A method of removing a pluggable module from a cage, the method comprising:
applying a force to a handle of a pull tab, the pull tab having attachment arms having distal ends and attachment mechanisms disposed at the distal ends;
transmitting a majority of the force through a reinforcement line embedded in the pull tab to the attachment mechanisms, the majority of the force bypassing the attachment arms; and
transmitting the force to the pluggable module coupled to the attachment mechanisms so as to withdraw the pluggable module from the cage.

11. The method of claim 10 , wherein the reinforcement line is coupled to the attachment mechanisms via an interference fit, solder, a weld, or an adhesive.

12. The method of claim 10 , wherein the attachment arms include a first attachment arm and a second attachment arm;
the attachment mechanisms include a first attachment mechanism disposed in the first attachment arm and a second attachment mechanism disposed in the second attachment arm; and
the reinforcement line extends from the first attachment mechanism through the first attachment arm, the handle, and the second attachment arm to a second attachment mechanism.

13. The method of claim 10 , wherein the reinforcement line is composed of one of: a metallic or non-metallic wire, a cord, or a strip.

14. 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;
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 first slide arm and a second slide arm, respectively, 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; and
a reinforcement strip having a first distal end that conforms to the first cavity and a second distal end that conforms to the second cavity.

15. The pull tab of claim 14 , wherein the reinforcement strip is configured to transmit a pulling force received at the handle to the first slide arm when inserted in the first cavity and to the second slide arm when inserted in the second cavity.

16. The pull tab of claim 15 , wherein the first attachment arm and the second attachment arm are comprised of a flexible material, 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.

17. The pull tab of claim 14 , wherein the reinforcement strip is embedded in the pull tab, and extends from the distal end of the first attachment arm, through the first attachment arm, the handle, and second attachment arm to a the distal end of the second attachment arm.

18. The pull tab of claim 14 , wherein the reinforcement strip is made a metallic or non-metallic material.

19. The pull tab of claim 14 , 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 a second slide arm.

20. The pull tab of claim 14 , wherein the first and second cavities and distal ends of the reinforcement strip are disposed in a corresponding pair of extensions extending substantially orthogonal from the distal ends of the first and second attachment arms.
