- the cable part 11 includes four cables (electric cable) having one pair of signal cables 12 a and 12 b for differential-mode transmission (differential mode), a power cable 13 a , and a GND cable 13 b .
- Each of these cables 12 a , 12 b , 13 a , and 13 b includes a conductor 14 as a core and an insulating coating 15 surrounding it.
- the conductor 14 may be either a solid wire of copper or a stranded wire of copper.
- the stranded wire may be one which is formed by twisting the core of copper wires and the covering thread of aramide fiber, with a layer of insulating resin covering them. This structure is applicable to any of the signal cables 12 a and 12 b , the power cable 13 a , and the GND cable 13 b .
- the signal cables 12 a and 12 b may be in the form of twisted pair, for example.
- the signal cables 12 a and 12 b are covered with a metal sheet 16 , which may be a copper or aluminum foil placed thereon or a copper or aluminum ribbon wound around them, with both structures combined together optionally.
- the metal sheet 16 which is not earthed, has the advantage of being free from the problem of bigtail that results from using a braided wire.

- the insulating coating 15 covering the conductors 14 and the covering layer 17 a variety of materials are used.
- materials such as polyethylene, polypropylene, PVC (polyvinyl chloride), and elastomer may be used.
- the resin containing magnetic powder 18 is a mixture of a synthetic resin and a magnetic powder.
- the synthetic resin includes, for example, styrene elastomer.
- a synthetic resin such as olefin elastomer and PVC other than styrene elastomer may be used.
- the magnetic powder includes, for example, Ni—Zn ferrite.
- Ni—Cu—Zn ferrite, Mn—Zn ferrite, and soft magnetic metal may be used, and other magnetic powder based on such metals as copper, magnesium, lithium, zinc, iron (e.g., permalloy), and cobalt may also be used.
- the resin containing magnetic powder 18 preferably contains ferrite in an amount equal to or more than 70 wt % and equal to or less than 95 wt %, typically 89 wt %. Ferrite in an amount equal to or more than 70 wt % is particularly effective in absorption of high-frequency noise. On the other hand, ferrite in an amount equal to or less than 95 wt % is effective in reducing adverse effects on moldability, flexibility, and mechanical properties such as tensile strength.
- the USB connector 21 includes a printed circuit board 22 , a plug 23 supported on the printed circuit board 22 , and a molded part 24 that covers the printed circuit board 22 supporting the plug 23 .
- the molded part 24 has the plug 23 protruding from one end thereof and also has the cable part 11 derived from the other end thereof.
- the printed circuit board 22 has on one side thereof terminals 25 a and 25 d , a common-mode choke coil (called common-mode filter occasionally) 26 for power source, and the capacitor (condenser) for noise removal (not depicted).
- the terminals 25 a and 25 d have the power cable 13 a and the GND cable 13 b connected thereto respectively.
- the printed circuit board 22 has on the other side thereof terminals 25 b and 25 c and a common-mode choke coil 27 .
- the terminals 25 b and 25 c are connected to the signal cables 12 a and 12 b respectively.
- the printed circuit board 22 has terminals 28 a , 28 b , 28 c , and 28 d , and the terminals 28 a , 28 b , 28 c , and 28 d extend from the substantially center to one end thereof.
- the plug 23 is supported on the printed circuit board 22 such that it covers that part of the printed circuit board 22 on which the terminals 28 a , 28 b , 28 b , and 28 c are formed.

- the insulating resin layer 24 a includes an insulating polymeric resin such as polypropylene
- the electromagnetic wave shielding layer 24 b includes carbon or ferrite and a polymeric resin capable of shielding, such as absorbing or reflecting, electromagnetic waves.
- the cable part 11 has on one end thereof the signal cables 12 a and 12 b , the power cable 13 a , and the GND cable 13 b , with their parts exposed without being covered by the covering layer 17 and the resin containing magnetic powder 18 (these parts will be called “uncovered parts” hereinafter).
- the uncovered parts of the cables 12 a , 12 b , 13 a , and 13 b are embedded in the insulating resin layer 24 a.
- the signal cables 12 a and 12 b have the uncovered parts at one end thereof formed such that they are shorter than the uncovered parts at one end of the power cable 13 a and the GND cable 13 b so that they do not come into contact with the electromagnetic wave shielding layer 24 b . This prevents signals from attenuating due to contact of the electromagnetic wave shielding layer 24 b with the uncovered parts of the signal cables 12 a and 12 b . In order to avoid contact between the electromagnetic wave shielding layer 24 b and the uncovered parts of the signal cables 12 a and 12 b , it is desirable that the uncovered parts of the signal cables 12 a and 12 b extend almost straight toward their respective terminals 25 b and 25 c.
- the signal cables 12 a and 12 b may be constructed such that the uncovered parts thereof are covered with an insulating covering material 12 c . This avoids contact between the electromagnetic wave shielding layer 24 b and the uncovered parts of the signal cables 12 a and 12 b .
- the insulating covering material 12 c includes, for example, an insulating tube, an insulating tape, an insulating film, a heat-shrinkable tube, a heat-shrinkable tape, and a heat-shrinkable film.
- the pUSB connector 31 is constructed in the similar way to the USB connector 21 mentioned above, such that the printed circuit board is covered with the molded part.
- the USB connector 21 is connected to the receptacle of a host 20
- the iUSB connector 31 is connected to the receptacle of a portable terminal 30
- the terminals 28 a , 28 b , 28 c , and 28 d of the USB connector 21 are a source terminal (pin 1 : Vbus terminal), a data terminal (pin 2 : D-terminal), a data terminal (pin 3 : D+terminal), and a ground terminal (pin 4 : GND terminal), respectively.
- Terminals 36 a , 36 b , 36 c , 36 d , and 36 e of the ⁇ USB connector 31 are a source terminal (pin 1 : Vbus terminal), a data terminal (pin 2 : D-terminal), a data terminal (pin 3 : D+terminal), an identifying terminal (pin 4 : ID terminal), and a ground terminal (pin 5 : GND terminal), respectively.
- the USB connector 21 has its terminals 28 b and 28 c connected to respective two terminals on one side of the common-mode choke coil 27 .
- Two terminals on the other side of the common-mode choke coil 27 are connected to two terminals on one side of a common-mode choke coil 32 arranged in the pUSB connector 31 through the signal cables 12 a and 12 b .
- Two terminals on the other side of the common-mode choke coil 32 are connected to the terminals 36 b and 36 c.
- the USB connector 21 has its terminals 28 a and 28 d connected to two terminals on one side of the common-mode choke coil 26 .
- a capacitor (condenser) 29 for noise removal is inserted between two terminals on the other side of the common-mode choke coil 26 .
- the two terminals on the other side of the common-mode choke coil 26 are connected to the terminals 36 a and 36 e of the pUSB connector 31 through the power cable 13 a and the GND cable 13 b .
- the pUSB connector 31 includes ferrite beads 33 and 34 .
- the ferrite beads 33 and 34 are arranged respectively in the power cable 13 a and the GND cable 13 b in the pUSB connector 31 .
- a resistor 35 for identification is connected to the terminals 36 d and 36 e.
- the signal cables 12 a and 12 b have two common-mode choke coils 27 and 32 inserted therein; however, one of them may be omitted.
- the pUSB connector 31 may be modified in constitution such that the power cable 13 a and the GND cable 13 b are connected to the common-mode choke coils in place of the ferrite beads 33 and 34 .
- both cables connected to the host side and the device side allow power supply. In this case it is desirable to provide both connector sides with the common-mode choke coils connected to the power cable 13 a and the GND cable 13 b.
- Each of the common-mode choke coils 26 , 27 , and 32 includes one common core and two coils wound thereon in the opposite directions.
- the common-mode choke coils 27 and 32 are inserted into each of the signal cables 12 a and 12 b as two data lines.
- the common-mode choke coil 26 is inserted into each of cables including the power cable 13 a and the GND cable 13 b as two power supply lines.
- the common-mode choke coils 26 , 27 , and 32 permit the passage of signal currents in differential mode and remove noise current in a common mode. That is, in the case of the differential mode, the two coils cause the currents to flow in the opposite directions, so that they do not function as an inductor. By contrast, in the case of the common mode, the two coils cause the currents to flow in the same direction, so that they function as the inductor. Being in the common mode, noise can be removed. In fact, however, the inductance component does not become null because part of a magnetic flux occurring in each coil becomes a leakage flux. Consequently, there is an instance in which this inductance component is non-negligible in a region where a signal frequency is extremely high. Moreover, it is possible to remove noise by means of the capacitor 29 for noise removal. It is also possible to remove high-frequency noise by means of the ferrite beads 33 and 34 .
- the foregoing enhanced performance on noise reduction in power transmission prevents the portable terminal 30 from decreasing in a reception level due to noise occurring in the battery charger and PC to which the USB connector 21 is connected.
- Impedance-frequency characteristics of the common-mode choke coil 27 (or 32 ) for signals is depicted in FIG. 6 .
- a solid line 41 denotes impedance-frequency characteristics in the common mode.
- a broken line 42 denotes impedance-frequency characteristics in the differential mode. It is to be noted, for example, that the impedance in the differential mode is low in the neighborhood of 100 MHz. This suggests that the effect on signal transmission is insignificant.
- Impedance-frequency characteristics of the common-mode choke coil 26 for power supply are depicted in FIG. 7 .
- a solid line 43 denotes impedance-frequency characteristics in the common mode.
- a broken line 44 denotes impedance-frequency characteristics in the differential mode. It is to be noted, for example, that the impedance in both the common mode and the differential mode is comparatively high in the neighborhood of 100 MHz. This suggests that it is possible to suppress the high-frequency components (or noise) in both of the modes.
- Insertion loss-frequency characteristics of the capacitor 29 for noise removal are depicted in FIG. 8 . This indicates that the capacitor 29 having a capacitance of 1.5 ⁇ F effectively suppresses noise.
- FIG. 9 depicts frequency characteristics for a loss factor ⁇ ′′ of the electromagnetic wave shielding layer 24 b containing ferrite and polymeric resin.
- the polymeric resin is polypropylene and the electromagnetic wave shielding layer 24 b contains ferrite in an amount of 80 wt %. It is noted from FIG. 9 that the loss factor ⁇ ′′ is as low as approximately 4 in the low-frequency range.
- the USB connector 21 is produced in the following manner.
- the printed circuit board 22 is provided thereon with the common-mode choke coils 26 and 27 as chip parts (noise filter) for anti-noise measure.
- the power cable 13 a and the GND cable 13 b are connected to the terminals 25 a and 25 d of the printed circuit board 22 respectively by soldering.
- the signal cables 12 a and 12 b are connected to the terminals 25 b and 25 c of the printed circuit board 22 respectively by soldering.
- the insulating resin layer 24 a as the inner molded part is formed by molding so that it fills the space around the printed circuit board 22 .
- the insulating resin layer 24 a is subsequently surrounded with the magnetic wave shielding layer 24 b as the outer molded part which is formed by molding. In this way, there is obtained the USB connector 21 .
- the ⁇ USB connector 31 is also produced by molding in the similar way to the USB connector 21 mentioned above.
- the above-mentioned method for producing the USB cable saves time for production of the USB cable because the USB connector 21 is prepared simply by covering the printed circuit board 22 with resin by molding. Also, covering the printed circuit board 22 with resin without any gap results in an improved shielding performance.
- USB Type-C is applicable not only to the USB cable but also to HDMI (registered trademark) cable and IEEE (Institute of Electrical and Electronics Engineers) 1394 cable.
- the cable part may be the ordinary USB cable.
- the molded part 24 further has the insulating resin layer 24 c surrounding the electromagnetic wave shielding layer 24 b as depicted in FIG. 10 .
- the insulating resin layer 24 c includes an insulating polymeric resin such as polypropylene. The insulating resin layer 24 c added to the molded part 24 realizes the improved shielding performance.
- the molded part has the insulating resin layer only.
- the insulating resin layer may have a configuration to fill the space surrounding the printed circuit board or the insulating resin layer may have a cavity around the printed circuit board.
- both the common-mode choke coil for power supply and the common-mode choke coil for signals are mounted on the same plane of the printed circuit board.
- a cable including:
- a cable part including at least one set of signal cables for differential transmission, a ground cable, and a power cable;
- the first connector and the second connector has a common-mode choke coil connected to the ground cable and the power cable.
- a connector having the common-mode choke coil further has a condenser for noise removal which is placed between the ground cable and the power cable.
- a connector having the common-mode choke coil further has a substrate having the common-mode choke coil mounted thereon and an insulating resin layer covering the substrate.
