Abstract

An optical connector comprising a connecting structure, an optical receiver located within the connecting structure, an optical transmitter located within the connecting structure, and a heat sink located within the connecting structure. The heat sink is configured to conduct heat away from the optical receiver and the optical transmitter. The optical receiver and the optical transmitter are thermally connected to the heat sink.

First claim

What is claimed is:

1. An optical connector comprising:
a connecting structure;
an optical receiver located within the connecting structure;
an optical transmitter located within the connecting structure; and
a heat sink located within the connecting structure, wherein the heat sink is configured to conduct heat away from the optical receiver and the optical transmitter and the optical receiver and the optical transmitter are thermally connected to the heat sink, the heat sink comprising a first section and a second section separated from each other, wherein the optical receiver is further located in the first section and the optical transmitter is further located in the second section, wherein the heat sink is movable along a surface of a dielectric structure connected to the heat sink within the connecting structure;
a first pin within the connecting structure and inserted into both the first portion of the heat sink and the dielectric structure; and
a second pin within the connecting structure and inserted into both the second portion of the heat sink and the dielectric structure.

2. The optical connector of claim 1 further comprising:
a connector system configured to connect the optical receiver and the optical transmitter to an optical fiber.

3. The optical connector of claim 2 , wherein the connector system is configured to be connected to one of a plastic optical fiber and glass optical fiber.

4. The optical connector of claim 1 wherein the heat sink is held by the dielectric structure in the connecting structure.

5. The optical connector of claim 4 , wherein the heat sink is connected to the dielectric structure by a thermal adhesive, wherein the thermal adhesive is thermally conductive and electrically insulating.

6. The optical connector of claim 4 , wherein the dielectric structure has a channel system and the heat sink is mounted in the channel system further comprising:
a thermal conductor configured to connect the heat sink to the dielectric structure in the channel system and a wall of the connecting structure.

7. The optical connector of claim 6 , wherein the thermal conductor is a thermal adhesive.

8. The optical connector of claim 1 , wherein the heat sink is thermally connected to the connecting structure.

9. The optical connector of claim 1 , wherein the heat sink is comprised of a number of materials selected from at least one of aluminum, copper, an aluminum alloy, copper-tungsten, a nickel-cobalt ferrous alloy, silicon-carbide in an aluminum matrix, and a dymalloy.

10. The optical connector of claim 1 wherein the first section further comprises a first hole and the second section comprises a second hole, the first hole and the second hole configured to receive at least one alignment tool to facilitate movement of the heat sink.

11. A method for manufacturing an optical connector, the method comprising:
connecting a dielectric structure to an interior of the optical connector;
placing a heat sink into the optical connector, the heat sink comprising a first section and a second section separated from each other, wherein the optical receiver is further located in the first section and the optical transmitter is further located in the second section, wherein the heat sink is movable along a surface of a dielectric structure connected to the heat sink within the connecting structure; and
positioning a first pin within the connecting structure and into both the first portion of the heat sink and the dielectric structure;
positioning a second pin within the connecting structure and into both the second portion of the heat sink and the dielectric structure;
connecting the first pin and the second pin within the dielectric structure in a desired position for the first pin and the second pin;
connecting an optical receiver and an optical transmitter to the dielectric structure.

12. The method of claim 11 , wherein positioning the first pin and the second pin comprises:
engaging a connector with the optical connector, wherein a third pin in the connector is moved to contact the first pin and a fourth pin in the connector is moved to contact the second pin, wherein moving of the third pin against the first pin and the moving of the fourth pin to contact the second pin places the first pin and the second pin into the desired position.

13. The method of claim 11 , wherein connecting the first pin and the second pin within the dielectric structure in the desired position for the first pin and the second pin comprises:
applying an adhesive to the first pin and the second pin while the first pin and the second pin are in the desired position; and
curing the adhesive.

14. The method of claim 11 , wherein connecting the optical receiver and the optical transmitter to the dielectric structure comprises:
connecting the optical receiver to the heat sink;
connecting the optical transmitter to the heat sink; and
connecting the heat sink to the dielectric structure with the optical receiver and the optical transmitter connected to the heat sink.

15. The method of claim 14 , wherein the heat sink is connected to the dielectric structure using a thermal adhesive.

16. The method of claim 11 , wherein positioning the first pin and the second pin comprises:
placing the first pin into a first hole in the dielectric structure; and
placing the second pin into a second hole in the dielectric structure.

17. The method of claim 11 , wherein the optical receiver is mounted in the first section and the optical transmitter is mounted in the second section.

18. The method of claim 11 , wherein the first section further comprises a first hole and the second section comprises a second hole, the method further comprising:
inserting an alignment tool into the first hole and the second hole.

19. The method of claim 18 further comprising:
moving the heat sink using the alignment tool.
