Abstract

A method of coupling polymeric components utilizing electromagnetic energy is disclosed. The method can include obtaining a first component having a first coupling portion, a second component having a second coupling portion, and a susceptor. The method can also include mating the first and second components such that the susceptor is proximate the first and second coupling portions. In addition, the method can include applying electromagnetic energy to the susceptor. The susceptor can convert the electromagnetic energy to heat, which can melt portions of the first and second coupling portions about the susceptor to couple the first and second components to one another upon solidification.

First claim

What is claimed is:

1. A method of coupling polymeric components of a cable junction utilizing electromagnetic energy, comprising:
obtaining a cable having a first coupling portion;
obtaining an end cap having a second coupling portion, and
obtaining a susceptor, wherein the susceptor is at least partially embedded within at least one of the first coupling portion or the second coupling portion;
mating the cable with the end cap such that the susceptor is proximate the first and second coupling portions; and
applying electromagnetic energy to the susceptor, wherein the susceptor converts the electromagnetic energy to heat, which melts portions of the first and second coupling portions about the susceptor to couple the cable and the end cap to one another upon solidification.

2. The method of claim 1 , wherein the end cap further comprises a third coupling portion and the method further comprises:
obtaining a shell having a fourth coupling portion;
obtaining a second susceptor, wherein the second susceptor is at least partially embedded within at least one of the third coupling portion or the fourth coupling portion;
mating the end cap with the shell such that the second susceptor is proximate the third and fourth coupling portions; and
applying electromagnetic energy to the second susceptor, wherein the second susceptor converts the electromagnetic energy to heat, which melts portions of the third and fourth coupling portions about the second susceptor to couple the end cap and the shell to one another upon solidification.

3. The method of claim 2 , wherein at least one of the first, second, third, or fourth coupling portions comprises a thermoplastic material.

4. The method of claim 3 , wherein the thermoplastic material comprises at least one of polyethylene (PE), polyetheretherketone (PEEK), polyetherketoneketone (PEKK), or polyolefin.

5. The method of claim 2 , wherein the cable has a fifth coupling portion and the shell has a sixth coupling portion, and the method further comprises:
obtaining a second end cap having seventh and eighth coupling portions;
obtaining a third susceptor, wherein the third susceptor is at least partially embedded within at least one of the fifth coupling portion or the seventh coupling portion;
obtaining a fourth susceptor, wherein the fourth susceptor is at least partially embedded within at least one of the sixth coupling portion or the eighth coupling portion;
applying electromagnetic energy to the third susceptor, wherein the third susceptor converts the electromagnetic energy to heat, which melts portions of the fifth and seventh coupling portions about the third susceptor to couple the cable and the second end cap to one another upon solidification; and
applying electromagnetic energy to the fourth susceptor, wherein the fourth susceptor converts the electromagnetic energy to heat, which melts portions of the sixth and eighth coupling portions about the fourth susceptor to couple the shell and the second end cap to one another upon solidification.

6. The method of claim 2 , wherein the end cap has a fifth coupling portion and the method further comprises:
obtaining a feedthrough having a sixth coupling portion; and
obtaining a third susceptor, wherein the third susceptor is at least partially embedded within at least one of the fifth coupling portion or the sixth coupling portion;
applying electromagnetic energy to the third susceptor, wherein the third susceptor converts the electromagnetic energy to heat, which melts portions of the fifth and sixth coupling portions about the third susceptor to couple the feedthrough and the end cap to one another upon solidification.

7. The method of claim 1 , wherein the first coupling portion comprises an opening and the second coupling portion is configured to fit within the opening.

8. The method of claim 1 , wherein the first coupling portion and the second coupling portion each have a cylindrical configuration.

9. The method of claim 1 , wherein the susceptor comprises at least one of a ring configuration, a coil configuration, a particulate, or a powder.

10. The method of claim 1 , wherein the susceptor comprises at least one of stainless steel, aluminum, molybdenum, niobium, silicon carbide, or graphite.

11. The method of claim 1 , wherein electromagnetic energy is applied by an inductor.

12. The method of claim 1 , wherein at least one of the first coupling portion or the second coupling portion is formed of a thermoplastic material.

13. The method of claim 1 , wherein the components form at least a portion of a data cable assembly.
