Abstract

A cord reel cable including a polymeric sheath with a conductive EMI drain and a method of manufacture therefor. The cord reel includes a cable comprising power and data conductors, as wells as a single drain wire which is grounded to a cord reel housing or spool or the like. The drain wire contacts an outer ETFE layer surrounding the cable in order to provide EMI shielding to the cable.

Claims (25)

1. A cord reel assembly comprising:

a) a housing,

b) a spool located within the housing; and

c) at least one cable for winding and unwinding around the spool, the cable having a substantially round cross-sectional profile comprising:

i) at least one data conductor;

ii) at least one drain wire;

iii) a conductive polymeric layer surrounding the at least one data conductor, and wherein the conductive polymeric layer contacts and surrounds at least a portion of the at least one drain wire, and at least one end of the at least one drain wire is not covered by the conductive polymeric layer and contacts at least one of the housing or the spool.

2. The cord reel assembly of claim 1 , wherein the conductive polymeric layer is ETFE.

3. A cord reel assembly comprising:

a) a housing,

b) a spool located within the housing; and

c) at least one cable for winding and unwinding around the spool, the cable having a substantially round cross-sectional profile comprising:

i) at least one data conductor;

ii) at least one power conductor;

iii) at least one drain wire;

iv) a conductive polymeric layer surrounding the at least one data conductor, and the at least one power conductor, wherein the conductive polymeric layer contacts the at least one drain wire.

4. The cord reel assembly of claim 3 , wherein the at least one end of the at least one drain wire is not covered by the conductive polymeric layer.

5. The cord reel assembly of claim 3 , wherein the conductive polymeric layer is ETFE.

6. A cord reel assembly comprising:

a) a housing,

b) a spool located within the housing; and

c) at least one cable for winding and unwinding around the spool, the cable having a substantially round cross-sectional profile comprising:

i) at least one drain wire;

ii) at least one conductor;

iii) a conductive polymeric layer surrounding the at least one conductor, wherein the conductive polymeric layer contacts the at least one drain wire and conducts to at least one of the housing or the spool.
