Abstract

A cable includes a cable part including at least one set of signal cables for differential transmission, a ground cable, and a power cable, and a first connector and a second connector arranged at both ends of the cable part. At least one of the first connector and the second connector has a common-mode choke coil connected to the ground cable and the power cable.

First claim

1 - 11 . (canceled)

12 . A cable comprising:
a cable part including at least one set of signal cables for differential transmission, a ground cable, and a power cable; and a first connector arranged at one end of the cable part and a second connector arranged at the other end of the cable part, wherein at least one of the first connector and the second connector has at least one common-mode choke coil connected to the ground cable and the power cable, wherein the first connector having the at least one common-mode choke coil further has a substrate having terminals and one common-mode choke coil mounted on one side of the substrate and terminals and another common-mode choke coil mounted on the other side of the substrate and an insulating resin layer covering the substrate, wherein the first connector having the one common-mode choke coil further has a condenser for noise removal, and wherein the terminals are connected to the power cable and the ground cable respectively and the terminals are connected to the at least one set of signal cables.

13 . The cable according to claim 12 , wherein the common-mode choke coil is provided for noise removal in a common mode and in a differential mode.

14 . The cable according to claim 12 , wherein the condenser for noise removal is placed between the ground cable and the power cable.

15 . The cable according to claim 12 , wherein the first connector having the common-mode choke coil further has an electromagnetic wave shielding layer covering the insulating resin layer.

16 . The cable according to claim 15 , wherein the electromagnetic wave shielding layer ( 24 b ) contains carbon or ferrite.

17 . The cable according to claim 15 , wherein the one set of signal cables is installed such that the one set of signal cables does not come into contact with the electromagnetic wave shielding layer.

18 . The cable according to claim 17 , wherein, on a side of the first connector having the electromagnetic wave shielding layer, one end of the one set of signal cables is shorter than one end of the ground cable and the power cable.

19 . The cable according to claim 15 , wherein, on a side of the first connector having the electromagnetic wave shielding layer, one end of the one set of signal cables is covered with an insulating covering material.

20 . The cable according to claim 12 , wherein one of the first connector and the second connector has the common-mode choke coil connected to the ground cable and the power cable, and the other of them has a ferrite bead arranged in the ground cable and the power cable.

21 . The cable according to claim 12 , wherein at least one of the first connector and the second connector further has a common-mode choke coil connected to the one set of signal cables.
