Description

The present invention relates to electric wires.

Conventionally, for example, for taking in commercial power, a plug having two electrodes at one end of the power cord or three electrodes to which a ground electrode is added is provided, and this plug is inserted into an outlet to supply power to the power supply line from the switchboard and the power cord. It is designed to connect with a wire. The other end of such a power cord is connected to, for example, a power supply unit of a personal computer (hereinafter, abbreviated as a personal computer) to form a power supply system for the personal computer.

Recently, there are many examples of forming a LAN (local area network) with multiple personal computers and printers (hereinafter referred to as personal computers for the sake of simplicity) to enable mutual data exchange. However, optical fibers are becoming widespread as LAN signal lines.
In this case, a personal computer as a terminal forming a LAN naturally requires power supply and an optical fiber connection, so the personal computer connects the power supply unit and the outlet with the above-mentioned power cord, and also connects the optical terminal and the LAN. The HUBs of the above are connected by an optical cable.

That is, at least the power cord and the optical cable extend from the personal computer, and the wiring is congested.
Therefore, as a countermeasure against wiring congestion, for example, Japanese Patent Application Laid-Open No. 2001-266665 and Japanese Patent Application Laid-Open No. 2001-318286 have proposed a composite cable in which a power cord and an optical cable are integrated.
That is, in these composite cables, the power supply line and the optical fiber are embedded in a common sheath, and the whole is made into one cable.

Hereinafter, embodiments of the present invention will be described in detail.
FIG. 1 is a diagram showing an embodiment applied to a connection between a switchboard and a personal computer.
A power supply line 18 and a ground line 19 extend from the switchboard 10 to an outlet 30 as a female connector attached to a wall surface of the room. The switchboard 10 is connected to the commercial power line 12.
The switchboard 10 is provided with a HUB 14 for forming a LAN, and an optical fiber 20 extends from the HUB 14 to an outlet 30.
A composite cable 16 in which an optical fiber is composited with a VVF (vinyl insulated vinyl sheath flat cable) is used between the switchboard 10 and the outlet 30.

The outlet 30 houses two power electrodes 40 and a ground electrode 45 in a casing 31 formed of a front plate 32 and a frame 36 coupled to the back side thereof.
The frame 36 is made of resin, and the power electrode 40 and the ground electrode 45 are molded into the frame 36 and stand up from the bottom wall of the frame toward the front plate 32, respectively.

Since the power electrode 40 and the ground electrode 45 are provided with a power supply line 18 inserted from the outside of the frame 36 and wire connection portions 41 and 46 that engage with the ground wire 19 in a wedge shape at their roots, the power supply line 18 And the ground wire 19 are connected to each electrode simply by inserting the exposed core wire, and are difficult to disconnect.
On the other hand, the tip sides of the power electrode 40 and the ground electrode 45 extend to the vicinity of the front plate 32, respectively, and the power electrodes 42 and 47 of the plug 60 as a connector on the male side, which will be described later, can be contacted with the power electrode and the ground electrode. It has become.
The energized portion 42 of the power electrode 40 of the outlet 30 is formed with a protruding portion 43 that protrudes on the contact surface side with the power electrode of the plug.

The ground electrode 45 rises from the bottom wall of the frame 36 and then offsets to the power electrode 40 side by a predetermined amount along the front plate 32, and the tip thereof serves as an energizing portion 47, and has an L shape as a whole.
In the front plate 32, electrode insertion holes 33 and 34 for receiving the power electrode of the plug and an electrode for receiving the ground electrode are inserted in the portions corresponding to the power electrodes 40 (energized portion 42) and the ground electrode 45 (energized portion 47). A hole 35 is provided.

As shown in FIG. 2, the electrode insertion holes 33 and 34 for the power electrode are arranged in parallel facing each other at predetermined intervals, and the electrode insertion holes 35 for the ground electrode are arranged below the intermediate positions of the electrode insertion holes 33 and 34. Has been done. The arrangement of these three electrode insertion holes is, for example, the same standard as the outlets on the market (for example, JIS C8303 outlet with 2-pole grounding electrode).
Note that FIG. 1 corresponds to the cross section of the AA portion in FIG. 2, and shows only one of the pair of power electrodes 40, and the power supply line 18 and the power supply line 88 described later also show only one side.

The frame 36 is further provided with an optical connector support portion 37 that reaches the front plate 32 from the bottom wall thereof.
The optical connector support portion 37 is provided with a slide hole 38 parallel to the insertion / removal direction of the ground electrode of the plug, and the slide hole 38 is aligned with the energized portion 47 of the ground electrode 45. For this reason, the side wall of the slide hole 38 is partially cut out so that the energized portion 47 of the ground electrode 45 faces the inside of the slide hole 38. Further, the slide hole 38 penetrates the bottom wall of the frame 36.

The optical connector 50 is slidably inserted into the slide hole 38 of the optical connector support portion 37. A guide pin 54 is provided on the side wall of the optical connector 50, and the guide pin 54 is guided to a long hole-shaped guide hole 39 formed on the side wall of the slide hole 38 to limit the slide range of the optical connector 50 to a predetermined range. It is supposed to be done. Further, the rotation of the optical connector 50 around the axis is restricted by engaging the guide pin 54 with the guide hole 39.

The guide pin 54 penetrates the guide hole 39 and protrudes to the outside of the side wall, and a tension spring 55 is provided between the tip thereof and the end of the optical connector support portion 37 on the front plate 32 side. As a result, the optical connector 50 is constantly urged toward the front plate 32, and in the free state, one end is in a position close to the energized portion 47 of the ground electrode 45.

FIG. 3 is an enlarged view of the optical connector 50.
The optical connector 50 includes a main body 51 having a ferrule hole 56 penetrating the axial center thereof and a cap 52 having a spring accommodating chamber 53, and a guide pin 54 extends from the main body 51.
The ferrule 90 supported by the connecting block 92 is inserted into the ferrule hole 56 from the cap 52 side.

FIG. 4 is an enlarged view showing a connection structure between the optical fiber 20 and the ferrule 90. FIG. 4A shows a vertical cross section, and FIG. 4B shows a cross section of the BB portion in (a).
Here, a ferrule for two cores is used. The optical fiber core wire 20a (covered with two optical fiber strands) extending from the power distribution board 10 is stripped, and the optical fiber strand 20b is inserted into the connecting block 92 coupled with the ferrule 90, and further, the optical fiber strands are further connected. The optical fiber 20c from which the protective member of 20b is peeled off extends to the tip of the ferrule 90 and is embedded.

As is known, the ferrule 90 is made of, for example, stainless steel (SUS) or zirconia ceramic, and its tip is polished together with the end face of the optical fiber 20c so as to be a plane perpendicular to the axial direction thereof.
In particular, as shown in FIG. 4B, the cross section of the ferrule 90 has a semicircular shape with a part cut.
In the present application, the optical fiber core wire 20a, the optical fiber wire 20b, and the optical fiber 20c in the optical fiber wire are collectively represented by "optical fiber" 20 unless it is necessary to distinguish them.

Returning to FIG. 3, a recess 57 for slidably accommodating the connecting block 92 is formed at the end of the main body 51 on the cap 52 side.
The cap 52 is fixed to the other end of the main body 51 (the side far from the energized portion 47 of the ground electrode 45) by screwing or adhering, and the spring 58 arranged in the spring accommodating chamber 53 urges the connecting block 92 to form the ferrule hole 56. It is pressed against the open end face on the side far from the energized portion 47.

The optical fiber 20 is connected to the connecting block 92 and the ferrule 90 through a hole provided in the bottom wall of the cap 52.
The ferrule hole 56 of the main body 51 of the optical connector 50 has a semicircular cross section that matches the shape of the cross section of the ferrule 90. As a result, the posture around the axis of the ferrule 90 with respect to the main body 51 is defined.
A slit 59 for receiving a protector portion, which will be described later, is formed on the end surface of the main body 51 of the optical connector facing the front plate 32.

Next, a male type plug 60 provided at the terminal of the composite cable 86 extending from the personal computer 80 and inserted into the outlet 30 will be described.
The plug 60 is plugged into an outlet 30, and connects the power supply line 88 and the optical fiber 20'of the composite cable 86 to the power supply line 18 and the optical fiber 20 on the switchboard 10 side, respectively, and also connects the ground wire 89 of the composite cable 86. Connect to the ground wire 19.
The plug 60 includes a cap plate 61 that fixes and supports the power electrode 65 and the ground electrode 70 by a resin mold, and a case 62 whose opening is sealed by the cap plate.
The surface of the cap plate 61 is a surface facing the front plate 32 of the outlet 30.

As shown in FIG. 5, the arrangement of the electrodes 65, 65, 70 corresponds to the electrode insertion holes 33, 34, 35 of the outlet 30 and has the same standard as that on the market, and the ground electrode 70 has the same standard. For example, it has a cross section that can be inserted into the ground electrode of an existing commercial power outlet installed on the wall surface of a house.
In FIGS. 1, 5 and 6 to 8 below, the thickness of the ground electrode 70 is drawn large for easy understanding.

As shown in FIG. 1, one end of the power electrode 65 extends vertically outward from the wall surface of the cap plate 61 to serve as a contact portion with the energized portion 42 of the power electrode 40 of the outlet 30. The other end of the power electrode 65 is a connection portion with the power supply line 88 in the case 62.
A round hole 66 that engages with the bulging portion 43 formed in the energizing portion 42 of the power electrode 40 of the outlet 30 is provided near the tip of the contact portion of the power electrode 65. The engagement relationship between the bulging portion 43 and the round hole 66 has a known structure, which enhances the function of preventing the plug 60 from coming off.
One end of the ground electrode 70 also extends vertically outward from the wall surface of the cap plate 61 to serve as a contact portion of the ground electrode 45 of the outlet with the energized portion 47. The other end of the ground electrode 70 is a connection portion with the ground wire 89 in the case 62.

FIG. 6 is an enlarged view showing the ground electrode 70 taken out.
The ground electrode 70 includes a tubular portion 71 having a bottom wall 72 at the outer tip portion, and a protector portion 78 extending outward from the tip end (bottom wall 72) of the tubular portion 71.
The protruding length of the tubular portion 71 from the cap plate 61 is set shorter than that of the power electrode 65.
A connecting block 92'supporting the ferrule 90'is slidably housed on the tip side of the cylinder portion 71, and an inner cylinder 73 is inserted and fixed on the root side of the tip of the inner cylinder 73 and the connecting block 92'. A spring 58'is arranged between them. The connecting block 92'is urged by the spring 58'and pressed against the bottom wall 72 of the inner cylinder 71. The ferrule 90'extending from the connecting block 92' extends outward through the hole 75 provided in the bottom wall 72.

Although not particularly shown, the hole 75 of the bottom wall 72 has a shape consistent with the cross section of the ferrule 90', which defines the axial orientation of the ferrule 90'. The posture of the ferrule 90'is set to match the posture of the ferrule 90 at the optical connector 50 of the outlet when the plug 60 is inserted into the outlet 30.
The shapes and sizes of the ferrule 90'and the connecting block 92'are the same as those of the ferrule 90 and the connecting block 92 shown in FIG.

As shown in FIG. 6, the protector portion 78 surrounds the ferrule 90'protruding from the bottom wall 75 with a predetermined gap, and a part of the outer peripheral surface of the tubular portion 71 is extended in the axial direction as it is. It is a thing.
The range in which the protector portion 78 surrounds the ferrule 90'is preferably a semicircle or more in the cross section. Further, the length of the protector portion 78 is preferably the same as or slightly shorter than the maximum protruding length of the ferrule 90'when the connecting block 92'is pressed against the bottom wall 72.

The length of the tubular portion 71 protruding from the wall surface of the cap plate 61 is such that when the plug 60 is inserted into the outlet 30 and the cap plate 61 and the front plate 32 come into contact with each other, the bottom wall 75 of the tubular portion 71 and the optical connector 50 It is set so that a slight gap is formed between the end face and the end face, but even if the bottom wall 72 and the end face of the optical connector 50 come into contact with each other due to an error or the like, the optical connector 50 is slidable, so that an error occurs. Is absorbed. Further, the depth of the slit 59 of the optical connector 50 is also set so that the protector portion 78 does not bottom out, but even if there is an error, it is absorbed in the same manner.

Returning to FIG. 1, the composite cable 86 from the personal computer 80 is pulled into the case 62 through the hole provided at the top thereof, and the power line 88 and the ground wire 89 are the roots of the power electrode 65 and the ground electrode 70 as described above. It is connected to (connection part) by caulking or the like. Further, the optical fiber 20'is connected to the connecting block 92'(and ferrule 90') through the inner cylinder 73 of the ground electrode.
The connection structure between the optical fiber 20'and the connecting block 92'and the ferrule 90' is the same as that shown in FIG.

FIG. 7 shows a connection state in which the plug 60 is inserted into the outlet 30 in the above configuration.
The power electrode 65 of the plug 60 comes into contact with the energized portion 42 of the power electrode 40 of the outlet 30 to be in a power energized state, and the power supply line 18 and the power supply line 88 are connected.
The ground electrode 70 of the plug 60 has its tubular portion 71 in contact with the energized portion 47 of the ground electrode 45 of the outlet 30, and the ground wire 19 and the ground wire 89 are connected.
Then, the ferrule 90'protruding from the tip of the tubular portion 71 enters the ferrule hole 56 of the optical connector 50 of the outlet, and the tip of the ferrule 90 comes into contact with the tip of the ferrule 90 housed in the ferrule hole.

At this time, since the orientations of the ferrules 90 and 90'in the axial direction are set to coincide with each other, the two-core optical fibers on the end faces of the ferrules face each other with high accuracy. As a result, the optical fiber 20 and the optical fiber 20'are connected.
During this period, the protector portion 78 that protects the ferrule 90'protruding from the tubular portion 71 is received by the slit 59 of the optical connector 50, so that it does not interfere with the optical connector 50.

FIG. 8 shows a state when a normal power plug is inserted into an outlet.
Conventionally, in the normal plug 60Z, the ground electrode 70Z has a protruding length equivalent to that of the power electrode 65, but the power electrode 65 comes into contact with the energized portion 42 of the power electrode 40 of the outlet 30 and becomes an energized state to generate electric power. The supply line 18 and the power supply line 88 are connected. Further, the ground electrode 70Z of the plug 60Z also contacts the energized portion 47 of the ground electrode 45 of the outlet, and the ground wire 19 and the ground wire 89 are connected.

On the other hand, since the length of the ground electrode 70Z is larger than the tubular portion 71 of the ground electrode 70 of the plug 60 in the embodiment, the tip of the ground electrode 70Z comes into contact with the optical connector 50. Here, since the optical connector 50 is slidable along the slide hole 38, when pushed by the ground electrode 70Z of the plug 60Z, it escapes to the outside against the tension spring 55, and the ground electrode 70Z and the optical connector 50 Does not interfere.
As described above, the outlet 30 can be plugged into a conventional general plug 60Z that is not compatible with optical fibers, and in this case as well, a power energized state can be obtained as in the conventional case.

Next, the composite cable 86 will be described.
As the composite cable 86, for example, the above-mentioned Japanese Patent Application Laid-Open No. 2001-266665, Japanese Patent Application Laid-Open No. 2001-318286, and other proposed cables can be used, but in the present embodiment, a more preferable embodiment is used. The composite cable 86 has the structure shown in FIG.
That is, the composite cable 86 has a circular shape as a whole in its cross section, and the insulator 111 inside the composite cable 86 has three non-circular blocks 112 point-symmetrical with respect to the central axis O.

The outer circumference of each block 112 is an arcuate surface 113, and the inner circumference is an arcuate surface 114 that is convex toward the central axis O. The top of the arcuate surface 114 has a gap of a predetermined amount d from the central axis O, whereby the arcuate surface 114 is defined between the three blocks 112, and the arm 115 is extended in three directions. S is formed.
A chamfer is formed at the outer peripheral corner of the insulator 111 on the radial line passing from the central axis O to the tip of each arm 115 to form a notch 118 in appearance, and connects the tip of each arm 115 and the notch 118. The diameter line is a section line 117 between the blocks 112.

The outer circumference of the block 112 is covered with a sheath 110 having a ring-shaped cross section, and an optical fiber 20'is arranged on the central axis O in the internal space S. Further, spacers 125 are attached to the optical fiber at predetermined intervals in the longitudinal direction thereof.
At the center of each block 112, a conductor 120 as a power line 88 and a ground line 89 is arranged.
It is preferable that the tip position of each of the above-mentioned arms 115 reaches the envelope 122 of each conductor 120.
The sheath 110 and the insulator 111 are each made of a polyvinyl chloride resin or the like.

In the above configuration, for example, the optical fiber 20'is surrounded by the center, and each block 112 of the insulator 111 is extruded while wrapping the conductor 120 and put together into one, so that each block 112 is in contact with the partition line 117. Then, it is realized by covering the outer periphery of the insulator 111 with the sheath 110 by the same extrusion molding.
According to this composite cable 86, when the plug 60 is inserted into the outlet 30, and the end faces of the ferrules 90 and 90'are in contact with each other and slightly retracted against the springs 58 and 58', respectively, the light connected to the ferrule The fiber can escape in a wide space, and an unreasonable external force does not reach the optical fiber 20'.
Further, even when an external force is applied to the cable from the lateral direction such as being stepped on, the so-called cushion function is exerted by the space S formed in the center of the inside, and the optical fiber is protected.

In addition, although it is not a recommended wiring process, the optical fiber 20'can escape from the central axis O position to the region of the arm 115 even when the composite cable is bundled in a bowed state when the composite cable is too long, and the optical fiber. Unreasonable external force does not reach.
Therefore, the tensile strength body for protecting the optical fiber, which is always required for the conventional optical cable, is not required.
Further, since the conductor 120 is arranged point-symmetrically around the central axis O, the connection between the power electrode and the plug 60 in which the ground electrode is similarly arranged is particularly smooth and easy.
Since the sheath 110 is covered on the outside of the block 112 here, it is not necessary to join the blocks 112 to each other, but if the sheaths are not covered, the blocks 112 may be joined to each other by the lane marking 117. In this case as well, the dividing line 117 between the blocks 112 of the insulator is short, and a notch 118 is formed on the outer periphery of the dividing line 117. Therefore, when wiring, the dividing line 117 between the blocks 112 of the cable terminal It becomes a composite electric wire that can be easily separated.
Although the composite cable 16 is based on VVF as described above, the same structure as the composite cable 86 may be adopted.

In the present embodiment, the plug 60 corresponds to the male side connector, and the outlet 30 corresponds to the female side connector.
The position of the ferrule 90'in the state where the spring 58'in the plug 60 constitutes the first urging means and the connecting block 92'is pressed against the bottom wall 72 of the tubular portion 71 corresponds to the first predetermined position.
The position of the ferrule 90 in a state where the spring 58 in the outlet 30 constitutes the second urging means and the connecting block 92 is pressed against the opening end surface of the ferrule hole 56 of the optical connector 50 corresponds to the second predetermined position.
Further, the tension spring 55 in the outlet 30 constitutes a third urging means, the guide pin 54 is restricted to the guide hole 39, and the optical connector 50 is closest to the energized portion 47 of the ground electrode. The position corresponds to the third predetermined position.

The present embodiment is configured as described above, and the paired outlet 30 and the plug 60 are connected to the power electrodes 40 and 65, the ground electrodes 45 and 70, and the optical fibers 20 and 20', respectively, and the ground electrode 45. , 70 has ferrules 90 and 90'arranged coaxially with 70, and when the power electrode and the ground electrode are connected to the power electrode and the ground electrode of the other party, their end faces are the ferrules of the other party. Since it faces the end face of the power supply system, the power supply system and the optical fiber can be connected at the same time by simply inserting the plug 60 into the outlet 30. Therefore, the wiring around the connection portion can be simplified by combining the power line 88 and the like with the composite cable 86 in which the optical cable 20'is integrated.

In particular, in the plug 60, the power electrode 65 and the ground electrode 70 extend in parallel with each other from the cap plate 61, and the ground electrode 70 forms a tubular portion 71 having a bottom wall 72 on the tip side, and the ferrule 90'is a tubular portion. It is held by 71 and is configured to protrude outward from the bottom wall 72, and has a shape that meets the specifications of a normal male plug with a ground electrode, so it is compatible with conventional male plugs.

The outlet 30 is also an optical connector having a current-carrying portion 42, 47 in which the power electrode 40 and the ground electrode 45 come into contact with the other power electrode 65 and the ground electrode 70, and a ferrule hole 56 on the back side of the current-carrying portion 47 of the ground electrode. 50 is provided, and the ferrule hole 56 is configured to hold the ferrule 90 on the side away from the energized portion 47 of the earth electrode and to accept the other ferrule 90'from the opening on the energized portion 47 side. Since the energizing portions 42 and 47 are arranged so as to correspond to the plug 60 and satisfy the standard of a normal female plug, it is compatible with the conventional female plug.

Further, the ferrule 90'of the plug 60 is positioned at a position where the connecting block 92'is pressed against the bottom wall 72 of the tubular portion 71 while being urged outward by the spring 58'. , It is slidable with respect to the tubular portion 71 of the ground electrode. Therefore, when the ferrule 90'receives an external force such as contact with the ferrule 90 of the outlet when the plug 60 is inserted into the outlet 30, it retracts in the axial direction against the spring 58'and absorbs the external force to absorb the ferrule 90. Set the surface pressure on the end face of'to an appropriate level.

The ferrule 90 of the outlet 30 is also urged by the spring 58 in the direction of the energized portion 47 of the ground electrode, and the connecting block 92 is pressed against the opening end surface on the side far from the energized portion 47 of the ferrule hole 56 of the optical connector 50. Although it is positioned at the position, it is slidable with respect to the ferrule hole 56, so when it comes into contact with the ferrule 90'of the plug 60 that has entered the ferrule hole 56 through the opening on the energizing portion 47 side, the spring 58 is engaged. The surface pressure between the end faces of the ferrules becomes an appropriate level at a position where the urging forces applied to the ferrules 90 and 90'are balanced by retreating in the axial direction.

Since the ground electrode 70 of the plug 60 includes a protector portion 78 extending outward from the bottom wall 72 of the tubular portion 71, even if the ferrule 90'protrudes from the tubular portion 71, it covers it and another object collides with it. Even if there is, damage to the ferrule 90'is prevented. Since the outer shape of the protector portion 78 is within the outer shape cross section of the tubular portion 71, the function as a ground electrode is not impaired.

Further, the optical connector 50 of the outlet 30 is urged by the tension spring 55 and one end is set at a position close to the energized portion 47 of the ground electrode 45, but since it is slidable in the axial direction, the outlet 30 Even if the length of the ground electrode of the plug inserted into the plug interferes with the optical connector at the set position, the sliding of the optical connector 50 prevents the interference. As a result, compatibility can still be maintained even if the length of the ground electrode of a normal male plug fluctuates.

The composite cable 86 is assumed to extend from the inside of the personal computer 80, but if the composite cable and the personal computer can be attached to and detached from each other, the composite cable 86 is made to correspond to the connector of the personal computer having the protruding electrodes like the plug 60. At the other end of the cable, a female plug 100 having a structure similar to that of the outlet 30 and having an appearance illustrated in FIG. 10 may be provided.
Similarly, in the embodiment, the female connector is the outlet 30 installed on the wall surface of a building or the like, but the present invention is not limited to this form, and the female plug 100 shown in FIG. 10 may be used.

The optical fibers 20 and 20'are aligned by matching the cross-sectional shape of the ferrule holes 56 with the cross-sectional shapes of the ferrules 90 and 90', but in addition, they are integrally coupled with the ferrules 90 and 90'. By making the cross section of the connecting blocks 92, 92'supporting the ferrule, for example, a quadrangle other than a circle, and matching the cross section of the slide region of the connecting block with the cross section shape of the connecting block, the ferrule 90, 90' It is possible to regulate the posture of and align with high accuracy.
Although an example using two-core optical fibers 20 and 20'has been shown, the number of cores of the optical fiber may be set as needed, and a ferrule corresponding to the number of cores may be used.
In particular, in the case of a single core, by setting an optical fiber at the axis of the ferrule, the cross section of the ferrule can be made circular without the need to regulate the posture.

The connection structure between each electrode and the power supply line, the power supply line, and the ground line is not limited to the one shown in the drawing, and a known structure can be arbitrarily adopted.
In addition, the arrangement and size of the male and female power electrodes and ground electrodes are based on the standards for plugs and outlets for commercial power supplies, but if the standards are revised or the standards differ from country to country, It may be set as appropriate to meet the standards in each region.
Although the protector portion 78 covers a part of the periphery of the ferrule 90'protruding from the tubular portion 71 of the ground electrode 70, it may surround the entire circumference.

Furthermore, in the embodiment, the ferrule connected to the optical fiber on the plug side is supported by the ground electrode, but the cross section of the power electrode can be tubular regardless of the presence or absence of the ground electrode. For example, the ferrule may be supported by a power electrode instead of the ground electrode. It is also possible to allocate a single core ferrule to each power electrode. In this case, the optical connector 50 on the outlet side is also arranged on the back side in the axial direction of the corresponding power electrode. Regardless of which electrode is supported, the optical fiber is arranged on the central axis by adopting the cross-sectional structure of the composite cable 86, so that it can be easily routed.

Further, by forming the ferrule on the plug side with a metal material having good conductivity, the ferrule itself can also be used as a power electrode or a ground electrode.
In this case, the ferrule hole 56 of the optical connector 50 also has a large diameter corresponding to the ferrule on the plug side.
Further, the optical connector 50 can also be used as a power electrode or a ground electrode.

In the embodiment, the power / optical composite connection structure by connecting the outlet 30 and the plug 60 is shown as an example in which the personal computer 80 is connected to the HUB 14 of the optical LAN provided on the switchboard 10. In addition to personal computers, TVs and video devices, as well as DVD recorders that download high-definition video from the outside through a broadband router connected to an external optical fiber network, can be connected to each of these devices and the HUB14. It can be applied as it is when connecting between.

Further, for example, when wireless communication is interposed in the connection between the HUB 14 and the notebook computer, it can be provided as a host-side adapter that can be connected to the outlet 30 by the plug 60.
FIG. 11 shows an example of connection between the host wireless adapter 93 as the host side adapter and the notebook computer 97.
The host wireless adapter 93 includes an optical LAN / USB protocol conversion unit 94 and a wireless USB host 95. The plug 60 described in the embodiment is connected to the host wireless adapter 93, and the power supply line 88 and the ground line 89 are power supplies (not shown) for driving the optical LAN / USB protocol conversion unit 94 and the wireless USB host 95. The optical fiber 20'is connected to the optical LAN / USB protocol conversion unit 94 while being connected to the unit.

The optical LAN / USB protocol conversion unit 94 converts the LAN signal transmitted by the optical fiber 20'from the HUB 14 of the switchboard via the outlet 30 according to the USB protocol, and outputs the LAN signal to the wireless USB host 95. The wireless USB host 95 transmits a USB signal as a radio wave from the antenna 96. On the other hand, the notebook computer 97 is provided with the wireless USB device 99, and receives the transmitted radio wave by the antenna 98 to receive the USB signal. This is restored to a LAN signal through the USB / LAN protocol conversion unit, but the illustration is omitted because of the normal configuration.
As a result, for example, the notebook computer 97 can be easily connected to the LAN simply by inserting the plug 60 of the host wireless adapter 93 into the outlet 30 in the room where the notebook computer 97 is carried.
