Abstract

A system and method for placing an electro-optical assembly inside a panel. In accordance with various embodiments of the invention, the system includes a housing to house the electro-optical assembly. The housing comprises a top section, a bottom section, a front element, an attachment module, and a metallic plate. A latching unlatching mechanism facilitates removal of the hosing from the panel. The electro-optical assembly provides EMI shielding.

Claims

1. A system for containing an electro-optical assembly, the system being placed inside a panel, the system comprising:

a. a housing, the electro-optical assembly being placed in the housing, the housing including;

i. a top section; and

ii. a bottom section;

b. a front element, the front element connected to the housing, the front element guiding at least one communication link for accessing the electro-optical assembly, the front element including;

i. a first face; and

ii. a second face;

c. an attachment module, the attachment module connected to the front element of the housing, the attachment module mounting the housing within the panel, the attachment module including;

i. a split tee hairpin spring, the split tee hairpin spring comprising compressible latch points, wherein the latch points compress on insertion of the housing inside the panel to facilitate latching of the housing within the panel; and

ii. a fork element, wherein the fork element inter-engages with the split tee hairpin spring to facilitate unlatching of the housing from the panel; and

d. a metallic plate, the metallic plate comprising at least one hole to pass the at least one communication link passing through the front element to the electro-optical assembly, the metallic plate being attached to the second face of the front element.

2. The system according to claim 1, wherein the housing is a metallic clamshell.

3. The system according to claim 1, wherein the housing shields electro magnetic interference.

4. The system according to claim 1, wherein the top section comprises a plurality of heat conduits.

5. The system according to claim 1, wherein the bottom section comprises a plurality of heat conduits.

6. The system according to claim 1, wherein the latch points protrude from the housing.

7. The system according to claim 6, wherein the split tee hairpin spring comprises two pairs of slits, the two pairs of slits inter-engaging with the fork element.

8. The system according to claim 1, wherein the fork element comprises angular ends.

9. The system according to claim 6, wherein the split tee hairpin spring is placed at the bottom section of the housing.

10. The system according to claim 1, wherein the system further comprises a handle, the handle surrounding the first face of the front element, the handle being connected to the attachment module, the handle being pushed to latch the system with the panel, the handle being pulled to unlatch the system from the panel.

11. The system according to claim 1, wherein the communication link is selected from the group consisting of a fiber optic cable, a coaxial cable, and a twisted pair cable.

12. A system for placing an electro-optical assembly, the system being placed inside a panel, the system comprising:

a. a housing, the electro-optical assembly being placed in the housing, the housing including;

i. a top section; and

ii. a bottom section;

b. a front element, the front element connected to the housing, the front element guiding at least one communication link for accessing the electro-optical assembly, the front element including;

i. a first face; and

ii a second face;

c. a handle, the handle surrounding the first face of the front element, the handle being pushed to latch the system, the handle being pulled to unlatch the system;

d. a latching mechanism, the latching mechanism latching the system to the panel; and

e. an unlatching mechanism interengaging with the latching mechanism, the unlatching mechanism permitting the unlatching of the system from the panel, the unlatching mechanism comprises a fork element, the fork element being attached to the handle, the fork element comprising a pair of angular ends, each of the pair of angular ends inter-engaging with the latching mechanism.

13. The system according to claim 12, wherein the front element further comprises a metallic plate, the metallic plate being attached to the second face of the front element, the metallic plate having at least one hole to allow the passage of the at least one communication link.

14. The system according to claim 12, wherein the latching mechanism and the unlatching mechanism are interengaged with each other, the interengagement resulting in a relative motion between the latching mechanism and the unlatching mechanism.

15. The system according to claim 14, wherein the latching mechanism comprises a split tee hairpin spring, the split tee hairpin spring being attached to bottom section of the housing, the split tee hairpin spring comprising:

a. latch points, the latch points protruding from the housing;

b. two pairs of slits, the pairs of slits being an opening for the inter-engagement between the latching mechanism and the unlatching mechanism; and

c. two upstanding elements, each of the two upstanding elements being between each of the pairs of slits, the upstanding element facilitating the inter-engagement between the latching mechanism and the unlatching mechanism.

16. The system according to claim 15, wherein the latch points lock the housing within the panel.

17. The system according to claim 14, further comprising a plurality of heat conduits to cool the electro-optical assembly.
