JP 2008-159766 A

  However, when the above-described module having a wiring portion made of a flexible printed wiring board is used as wiring between casings that are relatively moved such as rotating and sliding, bending and twisting are limited. In particular, since the optical waveguide is laminated on the wiring portion, the shape of the wiring is limited as well as bending and twisting, and it is difficult to wire the housing space that becomes narrower as the function becomes more sophisticated.

Can be accommodated without causing damage, and the speed of communication using optical fibers can be increased.

Also, the end portion of the optical fiber connected to the optical component is bulky in length, but in the connecting member, the direction in which the optical fiber is connected to the optical component is the small diameter of the portion where the thin-diameter electric wire is connected to the connecting member. It intersects with the length direction of the electric wire . Therefore, the depth dimension of the connecting member can be suppressed as much as possible. Thereby, size reduction of a connection member can be achieved, for example, it can wire through the narrow part (for example, hinge) between housing | casing.

Hereinafter, an example of an embodiment of a composite harness and a manufacturing method thereof according to the present invention will be described with reference to the drawings.
As shown in FIG. 1, the composite harness 20 includes a plurality of (several to several tens) small-diameter coaxial cables 24 that are a kind of small-diameter electric wires and at least one (in this embodiment, one) optical fiber. And a wiring portion 26 composed of 25. The wiring part 26 is bundled with a resin tape, a synthetic fiber sleeve or the like at an intermediate part excluding both end parts 21a and 21b.

  The small-diameter coaxial cable 24 is configured to have a center conductor, an inner insulator, an outer conductor, and a jacket from the center toward the outer side in a radial section perpendicular to the center axis. Terminal treatment is applied to the portion connected to the connecting member, and the outer conductor, the inner insulator, and the center conductor are exposed step by step in a predetermined length.

The composite harness 20 may include a thin insulated wire having no external conductor in addition to the plurality of thin coaxial cables 24. As the small-diameter coaxial cable 24, for example , it is desirable to use a coaxial cable whose outer diameter is thinner than 0.30 mm. Thereby, the composite harness 20 can be easily bent.
The number of thin wires included in the composite harness 20 can be several to several tens.
When an electric circuit such as an FPC is compared with a small-diameter coaxial cable, the coaxial cable has an advantage that it has better shielding characteristics and less crosstalk. In addition, coaxial cables are easier to bundle as a bundle, and when passing through the inside of the hinge, even a hinge with a smaller inner diameter can be passed.

The optical fiber 25 is configured by coating a glass fiber made of a core and a clad with a resin, and a terminal treatment is applied to a portion connected to the optical component, so that the glass fiber is exposed. In the present embodiment, one optical fiber 25 is provided, but this optical fiber 25 may be provided with several fewer than the thin coaxial cable 24.
Comparing the planar waveguide and the optical fiber, the optical fiber is more suitable for wiring that is bent or twisted. The use of the planar waveguide is limited to those in which the wiring shape is close to a straight line.

  A bundle member 27 such as an adhesive tape or a sleeve is used to bundle the wiring portion 26 composed of the small-diameter coaxial cable 24 and the optical fiber 25. For example, the small-diameter coaxial cable 24 and the optical fiber 25 are wound around the small-diameter coaxial cable 24 and the optical fiber 25, or the small-diameter coaxial cable 24 and the optical fiber 25 are passed through the bundle member 27 composed of a sleeve. Optical fibers 25 are bundled. If necessary, a ground connection member may be used so that grounding is obtained at a predetermined portion.

  And in the wiring part 26 of the composite harness 20, the optical fiber 25 is arrange | positioned in the outermost layer of a bundle. The shape to be bundled may be an unspecified shape as long as a plurality of small-diameter coaxial cables 24 and optical fibers 25 are bundled together. Further, the bundling member 27 may be bundled by one, or may be divided into a plurality of pieces in the length direction and bundled at a plurality of locations. Further, it is preferable that the small-diameter coaxial cable 24 and the optical fiber 25 are bundled loosely so that their movements are not restricted. The optical fiber 25 may be wired along the bundled thin coaxial cable 24.

The plurality of small-diameter coaxial cables 24 and the optical fibers 25 are arranged at a predetermined pitch and arranged in parallel in a flat shape, and are connected to connectors 31 and 32 which are a kind of connection member.
The direction of the thin coaxial cable at the portion where the thin coaxial cable is bundled at the wiring portion 26 with respect to the arrangement direction of the thin coaxial cables 24 in the connectors 31 and 32 (left and right in FIG. 1) (in FIG. 1). The vertical direction is substantially orthogonal and is T-shaped.

Next, the connectors 31 and 32 will be described.
As shown in FIGS. 2 and 3, in the connectors 31 and 32, a plurality of connection terminals 41 are arranged on a connector main body 43. The pitch of the connection terminals 41 can be 0.3 to 0.5 mm.
The connector main body 43 has a cable connection portion 44 to which a plurality of small-diameter coaxial cables 24 are connected and a fiber connection portion 45 to which the optical fiber 25 is connected.
The cable connecting portion 44 is provided with a cable housing portion 46 in which the respective terminals of the small-diameter coaxial cable 24 subjected to terminal processing are housed and connected.

  A plurality of contacts 47 extending from the connection terminals 41 are disposed in the cable housing portion 46, and the center conductor 24 a of the small-diameter coaxial cable 24 is soldered to the contacts 47. The cable connecting portion 44 is formed with an outer conductor fixing portion 48 to which the ground bar 49 is attached. The outer conductor 24b of the small-diameter coaxial cable 24 is disposed and fixed to the outer conductor fixing portion 48 via the ground bar 49.

The fiber connection portion 45 of the connector main body 43 is provided with a wiring board accommodating portion 52 that can accommodate a wiring board 51 made of an FPC board. A plurality of contacts 47 extending from the connection terminals 41 are also arranged in the wiring board housing portion 52, and the wiring board 51 is housed in the wiring board housing portion 52, so that the contact 53 of the wiring board 51 becomes the contact 47. And conducted. Ten or more contacts 47 are required for one optical fiber.
An optical component 55 is mounted on the wiring board 51, and the optical fiber 25 is connected to the optical component 55.

The fiber connection portion 45 is formed with an introduction groove 56 that is curved in an arc shape in plan view, and the optical fiber 25 connected to the optical component 55 is disposed in the introduction groove 56.
The optical fiber 25 is guided substantially perpendicular to the connector length direction up to the connector 31, but is curved along the introduction groove 56, and the direction of connection to the optical component 55 is the wiring direction on the connector 43 of the thin coaxial cable 24. Will intersect. You may wire so that the optical fiber 25 may become diagonal. The angle formed by the connection direction of the optical fiber 25 with the arrangement direction of the thin-diameter wires (connector width direction) is preferably 0 to 60 degrees. When the optical fiber 25 is inclined, the angle is preferably 30 to 60 degrees.

Here, FIG. 4 shows an optical transmission line using the optical fiber 25. The optical transmission path includes an optical fiber 25 and optical components 55 and 55A provided at both ends of the optical fiber 25. The optical component 55 on the light transmission side includes a ferrule 61, a photoelectric conversion element 62, and an electric component 63. The light receiving side optical component 55A includes a ferrule 61A, a photoelectric conversion element 62A, and an electric component 63A. The optical fiber 25 is bent and connected to the optical components 55 and 55A in the depth direction of FIG.
The ferrules 61 and 61A are made of a material containing any of polyester resin, PPS resin, and epoxy resin, and are formed with insertion holes 61a and 61Aa into which the ends of the optical fiber 25 are inserted. The ferrules 61 and 61A have photoelectric conversion elements 62 and 62A attached to end faces 61b and 61Ab on the front side in the insertion direction of the optical fiber 25 into the insertion holes 61a and 61Aa (direction in which the optical fiber is connected). The optical axes of the optical fiber 25 and the photoelectric conversion elements 62 and 62A are linearly arranged. Since the ferrules 61 and 61A and the photoelectric conversion elements 62 and 62A are directly connected, the height and length of both can be minimized, and the size of the connecting portion 45 can be reduced. Therefore, the size of the connector can be reduced.

As the photoelectric conversion element 62 on the input side, a VCSEL (Vertical Cavity Surface Emitting Laser) for converting an electric signal into an optical signal is used, and as the photoelectric conversion element 62A on the output side, an optical signal is converted into an electric signal. PD (Photodiode) is used.
A driver IC that drives the VCSEL is used as the electrical component 63 on the input side, and a transimpedance amplifier (TIA) that amplifies a signal from the PD is used as the electrical component 63A on the output side. The TIA is preferably placed as close as possible to the PD.
Each optical component 55, 55A is connected by a wiring circuit printed on the wiring board. As a result, the optical components on the wiring board can be densely arranged to reduce the size of the connecting portion 45. Therefore, the size of the connector can be reduced.

In this optical transmission line, the electronic signal of the data filed by the data converter 64 made of a serializer is converted into an optical signal by the photoelectric conversion element 62 on the input side made of VCSEL, and the optical signal is converted into the optical fiber 25. Is input. On the output side of the optical fiber 25, the optical signal is converted into an electric signal by the photoelectric conversion element 62A made of PD, and the electric signal is returned to the original data format by the data converter 64A made of a deserializer.
It is not necessary to mount the data converters 64 and 64A composed of a serializer or a deserializer on the wiring board 51, and it is preferable not to mount a driver IC that generates noise on the wiring board 51. These are installed in the equipment.

  In the connectors 31 and 32 configured as described above, the connecting portion 42 is connected to a receptacle (connected portion) 71 provided on the wiring board as shown in FIG. The connection direction with respect to the receptacle 71 is a direction along the arrangement surface of the thin coaxial cable 24 and the optical fiber 25. Thereby, the thickness dimensions of the connectors 31 and 32 are suppressed.

Further, the connecting portion 42 of the connectors 31 and 32 is bent downward as shown in FIG. 6 or bent upward as shown in FIG. The direction perpendicular to the arrangement surface of the cable 24 and the optical fiber 25 may be used. In this way, the depth dimension of the connectors 31 and 32 can be suppressed. In particular, as shown in FIG. 7, when the optical component 55 is mounted on the upper portion and the connecting portion 42 is bent upward, the optical component 55 is disposed in the dead space, and the bulk of the thickness dimension is minimized. Can be suppressed.
As for the dimensions of the connector and the connecting portion (a state in which the thin wire and the optical fiber are connected), the depth is 3 to 5 mm and the height is 1 to 2 mm. The width (length in the arrangement direction) depends on the number of lines, but is several mm to several tens of mm.
In the composite harness of the present invention, a signal requiring high-speed communication is propagated using an optical fiber. Signals and power that do not require much communication speed are propagated using thin wires. Insulated wires may be used for low-speed signals. An insulated wire can also be used as the power line. When a slightly high-speed signal is propagated or when shielding is required, it is better to use a thin coaxial cable.

  As shown in FIGS. 8 and 9, in this embodiment, the composite harness 20 connects the two substrates 11 and 12 that are arranged one above the other and move horizontally in the front-back direction (the left-right direction in FIGS. 8 and 9). Has been. For example, the substrates 11 and 12 are each incorporated in a relatively sliding housing of a device such as a mobile phone.

  The composite harness 20 is connected to both the boards 11 and 12 so as to be U-shaped (or J-shaped) as a whole. Thereby, the composite harness 20 can be wired between both the boards 11 and 12 as a U-shape in the planar view direction of the boards 11 and 12. 8 shows a state in which both end portions 21a and 21b of the composite harness 20 are farthest away, and FIG. 9 shows a state in which both end portions 21a and 21b are closest. The horizontal movement distance of the substrates 11 and 12 is, for example, about 30 mm to 60 mm.

  The composite harness 20 is curved in the width direction of the substrates 11 and 12 (in the direction of the double-headed arrow W in FIG. 8A) as seen in a plan view. Since the widths of the substrates 11 and 12 are several centimeters, a sufficient bending diameter in this direction can be ensured. For example, as shown in FIG. 8A, if one end 21a of the composite harness 20 is connected to the right side (upper side in FIG. 8A) of the upper substrate 11 in the sliding direction, the other end The end 21b is connected to the left side (lower side in FIG. 8A) of the lower substrate 12 with respect to the sliding direction. The composite harness 20 is bent in a U-shape, but in order to reduce the space for housing the composite harness 20, it is better that the U-shaped width (interval between straight portions) is narrower. In addition, it is preferable that the optical fiber 25 is arranged on the outer peripheral side of the curve of the composite harness 20 to increase the radius of curvature as much as possible to reduce bending stress.

As yet another example, as shown in FIG. 10, the composite harness 20 can be used by being incorporated in a device such as a mobile phone in which the ends of the housing are rotatably connected by hinges.
In the form shown in FIG. 10, the first housing 1 and the second housing 2 of the mobile phone terminal 3 including the first housing 1 and the second housing 2 are connected by the composite harness 20.
In the mobile phone terminal 3, the end portions of the first housing 1 and the second housing 2 are rotatably connected by a hinge 4, and the positional relationship is changed by opening and closing. The first housing 1 and the second housing 2 have cable insertion holes 5 and 6 formed on end surfaces on the connection side thereof, and both ends of the composite harness 20 are respectively connected from the cable insertion holes 5 and 6. Has been introduced. In addition, a communication hole 4a is formed in the hinge 4, and the composite harness 20 is inserted into the communication hole 4a.
In the composite harness 20, the direction in which the optical fiber is connected to the optical component intersects with the length direction of the thin wire at the portion where the thin wire is connected to the connecting member, so that the depth dimension of the connecting member is suppressed as much as possible. It has been. Accordingly, the composite harness 20 can be passed through the narrow hinge 4 without causing damage, and the substrate included in the first housing 1 and the substrate included in the second housing are connected to each other, thereby enabling high-speed communication using an optical fiber. Can be achieved.

  In order to manufacture the composite harness 20, a plurality of small-diameter coaxial cables 24 and an optical fiber 25 having a sufficient extra length are prepared. Thereafter, the terminals of the small-diameter coaxial cables 24 are arranged in parallel, and the optical fiber 25 is arranged at the end of the arrangement of the small-diameter coaxial cables 24. Then, while holding the arrangement state of the thin coaxial cable 24 with a film, a jig or the like, the external conductor is exposed from the end of the thin coaxial cable 24 and is fixed together by a ground bar 49 by soldering or the like. Further, the insulator and the central conductor 24a are exposed stepwise to perform terminal processing. A ground bar 49 is attached to the outer conductor fixing portion 48 and soldered to a ground terminal or shell (not shown). Further, the center conductor 24 a is soldered to the contact 47 of the connectors 31 and 32. Next, the optical fiber 25 is arranged in the outermost layer with respect to the thin coaxial cable 24, and the wiring portion 26 composed of the thin coaxial cable 24 and the optical fiber 25 is bundled by a bundle member 27 such as an adhesive tape or a sleeve.

The optical fiber 25 exposes a glass fiber having a length necessary for insertion into the ferrule 61, and is inserted into the ferrule 61 of the optical component 55 on the wiring board 51 and fixed. Thereafter, the optical fiber 52 is fitted into the introduction groove 56 of the connectors 31 and 32, and the wiring board 51 is accommodated and fixed to the wiring board accommodating portion 52.
Thereby, the composite harness 20 in which the connection direction of the optical fiber 52 with respect to the optical component 55 is set to a direction intersecting the length direction of the small-diameter coaxial cable 24 in the portion where the plurality of small-diameter coaxial cables 24 are connected to the connection member. can get.

  As described above, the composite harness 20 includes a plurality of small-diameter coaxial cables 24 and at least one optical fiber 25, and connectors 21 a and 21 b of the small-diameter coaxial cable 24 and the optical fiber 25 are connected to the connectors 21. 31 and 32. Therefore, even a narrow accommodation space can be accommodated without causing damage, and the communication speed of the optical fiber 25 can be increased.

The composite harness 20 is bent and wired by being connected to the substrates 11 and 12. A hinge between the substrates 11 and 12 may be passed. And when the board | substrates 11 and 12 move relatively, bending and a twist are added to the composite harness 20. FIG.
At this time, in the case of a module having a wiring portion made of a flexible printed wiring board, bending and twisting are limited, and smooth movement of the boards 11 and 12 is hindered. In particular, when the optical waveguide is laminated on the wiring portion, the wiring shape is limited as well as bending and twisting, and it is difficult to accommodate in a limited accommodation space.

  In the composite harness 20 of this embodiment, since the space between the connectors 31 and 32 is the small-diameter coaxial cable 24 and the optical fiber 25, wiring can be performed in a narrow and accommodating space where bending and twisting occur. The movement of the substrates 11 and 12 is smooth, and the durability against bending and twisting is high. When the thin wire is a coaxial wire, the shielding effect is also high.

In the connectors 31 and 32, the direction of the optical fiber 52 connected to the optical component 55 intersects with the length direction of the thin coaxial cable 24 where the thin coaxial cable 24 is connected to the connecting member . The depth dimensions of the connectors 31 and 32 can be suppressed as much as possible. Thereby, size reduction of the connectors 31 and 32 can be achieved, and the composite harness 20 can be smoothly passed and wired to the narrow hinge part between housing | casings.
When the thin electric wire is the thin coaxial cable 24, a high shielding effect can be obtained.

In the above embodiment, the optical fiber 25 is wired from the cable connecting portion 44 side of the connectors 31 and 32. However, as shown in FIG. 11, the optical fiber 25 is wired from the end portion away from the cable connecting portion 44. May be.
In addition, the arrangement direction of the optical fibers 25 in the connectors 31 and 32 may be a direction that intersects with the direction in which the thin coaxial cable 24 is connected. You may wire to. When the optical fiber 25 is inclined, the angle is preferably 30 to 60 degrees.

  In the above embodiment, the end portions 21a and 21b of the composite harness 20 are connected to the connectors 31 and 32. However, as shown in FIG. 12, a wiring board made of an FPC board or a hard board instead of the connectors 31 and 32. The composite harness 20 may be configured by connecting to 72. In this case, the wiring board material 72 made of the FPC board or the hard board is attached to the boards 11 and 12. By providing a through hole or the like in the wiring board material 72, the connection terminal 41 is electrically connected to the back surface of the wiring board material 72 and can be connected to the substrates 11 and 12.

  In particular, in this case, by providing a relay member 73 such as an anisotropic conductive film (ACF) or an interposer having adhesiveness on the surface to which the composite harness of the wiring board material 72 is connected or the back surface thereof, by heating or pressurizing, It is preferable to connect the connection terminal 41 of the wiring board material 72 to the substrates 11 and 12 via the relay member 73. Thereby, the thickness dimension and the depth dimension of the wiring board material 72 can be suppressed, respectively, and further downsizing can be achieved. The connection direction of the wiring board member 72 and the substrates 11 and 12 via the relay member 73 is a direction orthogonal to the arrangement surface of the small-diameter coaxial cable 24 and the optical fiber 25 as in the case shown in FIG. .

  As a modification of this embodiment, a composite cable 80 including connectors 81 and 82 is shown in FIG. In this composite cable 80, by bending the small-diameter coaxial cable 24 in the vicinity of the connectors 81 and 82, the wiring portion 26 is wired substantially parallel to the arrangement direction of the small-diameter coaxial cables 24 to be L-shaped. ing. Further, the optical fiber 25 is wired from the end side away from the cable connecting portion 44 in the connectors 81 and 82. Since the optical components are mounted along the width direction of the connectors 81 and 82, the depth of the connectors 81 and 82 can be shortened. The optical fiber 25 may be wired on the side close to the cable connection portion 44. However, it is preferable that the optical fiber 25 is wired from the end side away from the cable connection portion 44 in that the bending of the optical fiber 25 is small.

In the case of the composite cable 80 provided with the connectors 81 and 82, the same effect as that of the composite cable 20 can be obtained. Moreover, in this composite cable 80, since the wiring portion 26 is wired substantially parallel to the wiring direction of the thin coaxial cable 24, the width dimension can be suppressed as much as possible. It is advantageous when passing through.
One of the connectors may be a T-shaped connection and the other may be an L-shaped connection method.
