Description

  The present invention relates to electric wires.

  Conventionally, for example, in order to take in commercial power, a plug having two electrodes or three electrodes obtained by adding a ground electrode to one end of a power cord is provided, and this plug is inserted into an outlet to connect a power supply line from a switchboard and a power supply of the power cord. It is designed to connect with a line. 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 have been many cases in which a LAN (Local Area Network) is formed by a plurality of personal computers and printers (hereinafter, represented by personal computers for simplicity) to enable mutual data exchange and the like. However, optical fibers are becoming widespread as LAN signal lines.
In this case, the personal computer as the terminal forming the LAN naturally needs power supply and optical fiber connection. Therefore, the personal computer connects the power supply unit and the outlet with the above-described power cord, and also connects the optical terminal and the LAN. HUBs (hubs) 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, JP-A-2001-266665 and JP-A-2001-318286 propose 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 buried in a common sheath to form a single cable as a whole.
JP 2001-266665 A JP 2001-318286 A

The conventional technique has a problem that the arm in the space formed by the arms in which the electric wires extend in three directions cannot reach the envelope enclosing the three conductors.
In addition, there is a problem that the current-carrying part on the first ferrule side cannot contact the holding part of the second ferrule.

  Therefore, an object of the present invention is to provide an electric wire in which an arm in a space formed by arms extending in three directions can reach an envelope enclosing three conducting wires.

In order to solve the above-mentioned conventional problems, the electric wire of the present invention has a cross section including a central axis, the arm of a space formed by each arm extending in three directions reaches an envelope enclosing three conductors, The conductor is disposed in each of the three adjacent blocks.
In addition, the arm of the space formed by each arm extending in three directions including the central axis has a cross section reaching the envelope enclosing the three commercial power conductors, and the commercial power conductor is provided in one insulator. It is characterized by being arranged in.

  According to the present invention, the electric wire can reach the envelope in which the arms of the space formed by the arms extending in three directions include the three conductors.

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 mounted on a wall surface in the room. The switchboard 10 is connected to a 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.
Between the switchboard 10 and the outlet 30, a composite cable 16 in which an optical fiber is composited with a VVF (vinyl insulated vinyl sheath flat cable) is used.

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

Since the power electrode 40 and the ground electrode 45 are provided at their roots with electric wire connecting portions 41 and 46 that engage with the power supply line 18 and the ground line 19 inserted from the outside of the frame 36 in a wedge shape, the power supply line 18 The earth wire 19 is connected to each electrode only by inserting the stripped core wire, and is hardly removed.
On the other hand, the leading ends of the power electrode 40 and the ground electrode 45 extend to the vicinity of the front plate 32, respectively, and are provided with current-carrying portions 42 and 47 that can contact the power electrode and the ground electrode of a plug 60 as a male connector described later. Has become.
In addition, a bulging portion 43 that protrudes from the contact surface of the power electrode 40 of the outlet 30 with the power electrode of the plug is formed.

After rising from the bottom wall of the frame 36, the ground electrode 45 is offset by a predetermined amount toward the power electrode 40 along the front plate 32, and the tip of the ground electrode 45 serves as a current-carrying portion 47, and has an overall L shape.
In the front plate 32, electrode insertion holes 33 and 34 for receiving the power electrodes of the plug and electrode insertions for receiving the ground electrode are provided at portions corresponding to the respective power electrodes 40 (the conductive portions 42) and the ground electrodes 45 (the conductive portions 47). A hole 35 is provided.

As shown in FIG. 2, the electrode insertion holes 33 and 34 for the power electrodes are arranged opposite to each other at predetermined intervals in parallel, and the electrode insertion hole 35 for the ground electrode is arranged below the intermediate position of the electrode insertion holes 33 and 34. Have been. The arrangement of the three electrode insertion holes is, for example, the same as that of outlets on the market (for example, JIS C8303, an outlet with a two-pole grounding electrode).
FIG. 1 corresponds to a section taken along the line AA in FIG. 2, and shows only one of the pair of power electrodes 40, and also shows only one side of the power supply line 18 and a power supply line 88 described later.

The frame 36 is further provided with an optical connector supporting portion 37 reaching from the bottom wall to the front plate 32.
The optical connector supporting portion 37 has a slide hole 38 parallel to the plugging / removing direction of the ground electrode of the plug, and the slide hole 38 is aligned with the conducting portion 47 of the ground electrode 45. For this reason, the side wall of the slide hole 38 is partially cut away so that the conducting portion 47 of the ground electrode 45 faces the inside of the slide hole 38. The slide hole 38 penetrates the bottom wall of the frame 36.

  An optical connector 50 is slidably inserted into the slide hole 38 of the optical connector support 37. A guide pin 54 is provided on the side wall of the optical connector 50, and the guide pin 54 is guided by the elongated hole-shaped guide hole 39 formed on the side wall of the slide hole 38, so that the sliding range of the optical connector 50 is limited to a predetermined range. It is supposed to be. The rotation of the optical connector 50 around the axis is restricted by the engagement of the guide pin 54 with the guide hole 39.

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

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 axis thereof and a cap 52 having a spring accommodating chamber 53, and a guide pin 54 extends from the main body 51.
A ferrule 90 supported by the connecting block 92 is inserted into the ferrule hole 56 from the cap 52 side.

4A and 4B are enlarged views showing a connection structure between the optical fiber 20 and the ferrule 90. FIG. 4A is a longitudinal section, and FIG. 4B is a section taken along line BB in FIG.
Here, a two-core ferrule is used. The coating of the optical fiber 20a (covering the two optical fibers) extending from the switchboard 10 is stripped, and the optical fiber 20b is inserted into the connecting block 92 connected to the ferrule 90. The optical fiber 20c from which the protective member 20b is peeled extends to the tip of the ferrule 90 and is embedded therein.

As is well 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 perpendicular to the axial direction.
In particular, as shown in FIG. 4B, the cross section of the ferrule 90 has a partially cut semicircular shape.
In the present application, the optical fiber 20a, the optical fiber 20b, and the optical fiber 20c in the optical fiber are collectively represented by the "optical fiber" 20 unless it is necessary to distinguish them.

Returning to FIG. 3, a concave portion 57 for slidably housing 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 (on the side far from the conducting portion 47 of the ground electrode 45) by screwing or bonding, and a spring 58 disposed in the spring accommodating chamber 53 urges the connecting block 92 to open the ferrule hole 56. It is pressed against the opening end face farther from the conducting section 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. Thereby, the attitude of the ferrule 90 around the axis with respect to the main body 51 is defined.
On the end face of the main body 51 of the optical connector facing the front plate 32, a slit 59 for receiving a protector section described later is formed.

Next, the male 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 inserted into the outlet 30 to connect 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. Connect to earth wire 19.
The plug 60 includes a cap plate 61 for fixing and supporting the power electrode 65 and the ground electrode 70 by resin molding, 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 is the same as that of those on the market corresponding to the electrode insertion holes 33, 34, 35 of the outlet 30. 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 of a house.
In FIGS. 1 and 5 and FIGS. 6 to 8 described later, 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, and serves as a contact portion of the power electrode 40 of the outlet 30 with the conducting portion 42 of the power electrode 40. The other end of the power electrode 65 is connected to a power line 88 in the case 62.
A round hole 66 is provided near the tip of the contact portion of the power electrode 65 so as to engage with the bulging portion 43 formed in the conducting portion 42 of the power electrode 40 of the outlet 30. The engagement relationship between the bulging portion 43 and the round hole 66 has a known structure, thereby enhancing 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, and serves as a contact portion of the ground electrode 45 of the outlet with the conducting portion 47. The other end of the ground electrode 70 is connected to a 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 an outer distal end portion, and a protector portion 78 extending outward from the distal end (bottom wall 72) of the tubular portion 71.
The length of the cylindrical portion 71 protruding from the cap plate 61 is set shorter than the power electrode 65.
A connecting block 92 ′ supporting a ferrule 90 ′ is slidably housed at the distal end side in the cylindrical portion 71, and an inner cylinder 73 is inserted and fixed at a root side, and the distal end of the inner cylinder 73 is connected to the connecting block 92 ′. A spring 58 'is disposed therebetween. The connecting block 92 ′ is urged by the spring 58 ′ and pressed against the bottom wall 72 of the inner cylinder 71. A ferrule 90 'extending from the connecting block 92' extends outward through a hole 75 provided in the bottom wall 72.

Although not particularly shown, the hole 75 in the bottom wall 72 has a shape that matches the cross section of the ferrule 90 ', thereby defining the attitude of the ferrule 90' around the axis. The posture of the ferrule 90 ′ is set so as to match the posture of the ferrule 90 in 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 the outer peripheral surface of the ferrule 90' extends a part of the outer peripheral surface of the cylindrical portion 71 in the axial direction as it is. Things.
It is preferable that the range in which the protector 78 surrounds the ferrule 90 ′ is equal to or more than a semicircle in a cross section. The length of the protector 78 is preferably equal to or slightly shorter than the maximum length of the ferrule 90 ′ when the connecting block 92 ′ is pressed against the bottom wall 72.

  The length of the cylindrical 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 abut, the bottom wall 75 of the cylindrical portion 71 and the optical connector 50 are in contact with each other. The gap is set to such a degree that a slight gap is formed between the optical connector 50 and the end face of the optical connector 50 even if the bottom wall 72 and the end face of the optical connector 50 come into contact due to an error or the like. Is absorbed. Further, the depth of the slit 59 of the optical connector 50 is set to such a degree that the protector portion 78 does not protrude from the bottom.

Returning to FIG. 1, the composite cable 86 from the personal computer 80 is drawn into the case 62 through a hole provided at the top, and the power line 88 and the ground line 89 are connected to the power electrode 65 and the ground electrode 70 as described above. (Connection part) by caulking or the like. The optical fiber 20 'is connected to the connecting block 92' (and the 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 power supply section 42 of the power electrode 40 of the outlet 30 to enter a power supply state, and the power supply line 18 and the power supply line 88 are connected.
The cylindrical portion 71 of the ground electrode 70 of the plug 60 comes into contact with the conducting 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 cylindrical portion 71 enters the ferrule hole 56 of the optical connector 50 of the outlet, and the tip comes into contact with the tip of the ferrule 90 housed in the ferrule hole.

At this time, since the postures of the ferrules 90 and 90 'in the direction around the axis are set to coincide with each other, the two-core optical fibers at the end faces of the ferrules face each other with high accuracy. Thereby, the optical fiber 20 and the optical fiber 20 'are connected.
During this time, the protector 78 that protects the ferrule 90 ′ protruding from the cylindrical 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.
In the conventional ordinary plug 60Z, the ground electrode 70Z has the same protruding length as the power electrode 65, but the power electrode 65 comes into contact with the power supply portion 42 of the power electrode 40 of the outlet 30 to be in a power-on state. The supply line 18 and the power supply line 88 are connected. In addition, the ground electrode 70Z of the plug 60Z also comes into contact with the conducting part 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 earth electrode 70Z is longer than the cylindrical portion 71 of the earth electrode 70 of the plug 60 in the embodiment, the tip of the earth electrode 70Z contacts the optical connector 50. Here, since the optical connector 50 is slidable along the slide hole 38, when pushed by the earth electrode 70Z of the plug 60Z, it escapes outward against the tension spring 55, and the earth electrode 70Z and the optical connector 50 Do not interfere.
As described above, the conventional plug 60Z, which is not compatible with an optical fiber, can be inserted into the outlet 30. In this case, the power supply 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-described JP-A-2001-266665 and JP-A-2001-318286, those proposed elsewhere can be used, but in the present embodiment, as a more preferable aspect, The composite cable 86 has a structure shown in FIG.
That is, the composite cable 86 has a circular cross section as a whole, and has three non-circular blocks 112 symmetrical about the central axis O with the insulator 111 therein.

The outer periphery of each block 112 is an arc surface 113 and the inner periphery is an arc surface 114 protruding 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, so that the space defined by each arcuate surface 114 between the three blocks 112 and having the arm 115 extended in three directions. S is formed.
A chamfer is formed at a corner of the outer periphery of the insulator 111 on a radial line passing from the central axis O to the tip of each arm 115, forming a notch 118 in appearance, and connecting the notch 118 to the tip of each arm 115. The diameter line serves as a division line 117 between the blocks 112.

The outer periphery of the block 112 is covered with a sheath 110 having a ring-shaped cross section, and an optical fiber 20 ′ is arranged in the internal space S on a central axis O. The optical fiber is provided with spacers 125 at predetermined intervals in the longitudinal direction.
In the center of each block 112, a conductor 120 as a power supply line 88 and a ground line 89 is arranged.
It is preferable that the position of the tip of each arm 115 described above reaches the envelope 122 of each conductor 120.
The sheath 110 and the insulator 111 are each formed of a polyvinyl chloride resin or the like.

In the above configuration, for example, by enclosing the optical fiber 20 ′ in the center and extruding each block 112 of the insulator 111 while wrapping the conductor 120, the blocks 112 are in contact with each other at the dividing line 117, Thereafter, the sheath 110 is also covered with the outer periphery of the insulator 111 by 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 'abut against each other and slightly retreat 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 when being stepped on, the so-called cushion function is provided by the space S formed in the center of the inside, and the optical fiber is protected.

Although not a recommended wiring process, the optical fiber 20 ′ can escape from the position of the central axis O to the area of the arm 115 even when the composite cable is bundled in a bow when it is too long. Unreasonable external force does not reach.
Therefore, a strength member for protecting the optical fiber, which is always required for the optical cable, is not required.
In addition, since the conductors 120 are arranged 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.
Here, since the sheath 110 is covered on the outside of the block 112, it is not necessary to join the blocks 112 to each other. However, when the sheath is not covered, the blocks 112 may be joined to each other at the dividing line 117. Also in this case, the dividing line 117 between the insulator blocks 112 is short, and the notch 118 is formed on the outer periphery of the dividing line 117. It becomes a composite 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 connector, and the outlet 30 corresponds to the female connector.
The position of the ferrule 90 'in a state where the spring 58' of the plug 60 is pressed by the connecting block 92 'against the bottom wall 72 of the cylindrical 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 face of the ferrule hole 56 of the optical connector 50 corresponds to the second predetermined position.
Further, the tension spring 55 of the outlet 30 constitutes a third urging means, and the guide pin 54 is regulated by the guide hole 39 so that the optical connector 50 is closest to the energizing portion 47 of the ground electrode. The position corresponds to the third predetermined position.

  The present embodiment is configured as described above, and the outlet 30 and the plug 60 forming a pair are connected to the power electrodes 40 and 65, the ground electrodes 45 and 70, and the optical fibers 20 and 20 ', respectively. , 70, and ferrules 90, 90 'arranged coaxially with each other. When the power electrode and the ground electrode are respectively connected to the power electrode and the ground electrode of the counterpart, the ferrules 90, 90' , The connection of the power supply system and the connection of the optical fiber are simultaneously performed only by a simple operation of inserting the plug 60 into the outlet 30. Therefore, the wiring around the connection portion is simplified by combining the power cable 88 and the composite cable 86 in which the optical cable 20 'is integrated.

  In particular, the plug 60 has a power electrode 65 and a ground electrode 70 extending parallel to each other and protruding from the cap plate 61. The ground electrode 70 has a cylindrical portion 71 having a bottom wall 72 on the distal end side, and the ferrule 90 'has a cylindrical portion. It is configured to be held by 71 and protrude outward from the bottom wall 72 and has a shape that meets the standard of a normal male plug with a ground electrode, so that it is compatible with a conventional male plug.

  The outlet 30 also has power supply portions 42 and 47 in which the power electrode 40 and the ground electrode 45 are in contact with the power electrode 65 and the ground electrode 70 of the other end, and an optical connector having a ferrule hole 56 on the back side of the power supply portion 47 of the ground electrode. In the ferrule hole 56, a ferrule 90 is held on the side of the ground electrode away from the conducting part 47, and the other ferrule 90 ′ is received from the opening on the conducting part 47 side. Since the conducting portions 42 and 47 are arranged so as to correspond to the plug 60 and satisfy the standard of a normal female plug, they are 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 cylindrical portion 71 in a state where the ferrule 90 ′ is urged outward by the spring 58 ′. , Can slide with respect to the cylindrical portion 71 of the ground electrode. Therefore, when the ferrule 90 ′ receives an external force such as abutting on the ferrule 90 of the outlet when the plug 60 is inserted into the outlet 30, the ferrule 90 ′ retreats in the axial direction against the spring 58 ′, absorbs the external force, and absorbs the external force. Set the surface pressure on the end face of 'to an appropriate level.

  The connecting block 92 was pressed against the opening end face of the ferrule hole 56 of the optical connector 50 on the side farther from the conducting portion 47 while the ferrule 90 of the outlet 30 was also urged toward the conducting portion 47 of the ground electrode by the spring 58. 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 from the opening on the side of the conducting part 47, the spring 58 The ferrule retreats in the axial direction, and the surface pressure between the end faces of the ferrule becomes an appropriate level at a position where the urging force applied to each ferrule 90, 90 'is balanced.

  Since the earth electrode 70 of the plug 60 includes the protector 78 extending outward from the bottom wall 72 of the cylindrical portion 71, even if the ferrule 90 'projects from the cylindrical portion 71, the ferrule 90' covers this and prevents other objects from hitting. Even if there is, damage to the ferrule 90 'is prevented. Since the outer shape of the protector 78 is within the outer cross section of the cylindrical portion 71, the function as a ground electrode is not impaired.

  Further, the optical connector 50 of the outlet 30 is urged by a tension spring 55 so that one end is set at a position close to the energizing portion 47 of the ground electrode 45. However, since the optical connector 50 is slidable in the axial direction, the outlet 30 is slidable. Even if the length of the ground electrode of the plug inserted into the optical connector interferes with the optical connector at the set position, the interference is prevented by retreating the optical connector 50 by sliding. Thereby, even if the length of the ground electrode of the normal male plug varies, the compatibility can be maintained.

The composite cable 86 extends from the inside of the personal computer 80. However, when the composite cable and the personal computer can be detachably connected to each other, the composite cable 86 is made to correspond to the connector of the personal computer whose electrode protrudes similarly to the plug 60. At the other end of the cable, a female plug 100 having the same structure as the outlet 30 and having an external appearance as shown in FIG. 10 may be provided.
Similarly, in the embodiment, the female connector is the outlet 30 installed on a wall surface of a building or the like, but the present invention is not limited to this configuration, and the female plug 100 shown in FIG. 10 may be used.

The alignment of the optical fibers 20 and 20 'is performed by matching the cross-sectional shape of the ferrule hole 56 with the cross-sectional shape of the ferrules 90 and 90'. In addition, the optical fibers 20 and 20 'are integrated with the ferrules 90 and 90'. Also, the cross sections of the connecting blocks 92, 92 'supporting the ferrules are made, for example, squares other than circles, and the cross section of the sliding area of the connecting blocks is matched with the cross sectional shape of the connecting blocks to form the ferrules 90, 90'. By adjusting the posture of the camera, highly accurate alignment can be performed.
Although the example in which the two-core optical fibers 20 and 20 'are used has been described, the number of optical fibers may be set as needed, and a ferrule corresponding to the number of optical fibers may be used.
In particular, in the case of a single core, by setting an optical fiber at the axis of the ferrule, it is possible to make the cross section of the ferrule circular without having to restrict 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 illustrated one, and any known structure can be adopted.
In addition, the arrangement and size of each power electrode and earth electrode on the male side and female side were the same as those for plugs and outlets for commercial power, but if the standards were revised or the standards differed from country to country, What is necessary is just to set suitably so as to satisfy the standard in each area.
The protector 78 covers a part of the periphery of the ferrule 90 ′ protruding from the cylindrical part 71 of the ground electrode 70, but may cover the entire circumference.

  Furthermore, in the embodiment, the ferrule connected to the optical fiber on the plug side is supported by the ground electrode. However, regardless of the presence or absence of the ground electrode, any cross section of the power electrode can be made cylindrical. For example, the power electrode may support the ferrule 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 disposed axially behind the corresponding power electrode. Regardless of which electrode is supported, since the optical fiber is arranged on the central axis by adopting the cross-sectional structure of the composite cable 86, it is easy to route.

Further, by forming the ferrule on the plug side with a highly conductive metal material, the ferrule itself can also be used as a power electrode or an earth electrode.
In this case, the ferrule hole 56 of the optical connector 50 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 combined power / optical connection structure by connecting the outlet 30 and the plug 60 is used to connect the personal computer 80 to the HUB 14 of the optical LAN provided on the switchboard 10. Not only personal computers, but also TVs and video devices, as well as DVD recorders that download high-definition video from the outside through a broadband router that connects to an external optical fiber network, etc. It can be applied as it is even when connecting between them.

Further, for example, when wireless communication is interposed in the connection between the HUB 14 and the notebook personal 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 a connection example between a host wireless adapter 93 as a host-side adapter and a notebook computer 97.
The host wireless adapter 93 includes an optical LAN / USB protocol converter 94 and a wireless USB host 95. The plug 60 described in the embodiment is connected to the host wireless adapter 93, and a power supply line 88 and a ground line 89 are connected to a power supply (not shown) for driving the optical LAN / USB protocol converter 94 and the wireless USB host 95. The optical fiber 20 ′ is connected to an optical LAN / USB protocol converter 94.

The optical LAN / USB protocol converter 94 converts the LAN signal transmitted from the HUB 14 of the switchboard via the outlet 30 through the optical fiber 20 ′ according to the USB protocol and outputs the converted 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 personal computer 97 is provided with a wireless USB device 99, which receives a transmission radio wave by the antenna 98 and receives a USB signal. This is restored to a LAN signal through a USB / LAN protocol conversion unit, but is not shown because of a normal configuration.
Thus, the notebook personal 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 into which the notebook personal computer 97 is carried.
