  As shown in FIGS. 1 to 5, the cable module 10 of this example is provided between the cable 101 and the cable 102, and includes an upper part 21, a lower part 22, end covers 23 and 24, and The housing | casing comprised by the cable protection components 25 and 26, the board | substrate 40, the protrusion parts 51 and 52, and the partition walls 61 and 62 are provided. The cable module 10 of the present example is a photoelectric conversion module that can convert an optical signal transmitted through the cable 101 into an electric signal and output the electric signal to the cable 102. The above-described parts constituting the module will be described in detail below. To do.

  The upper part 21 and the lower part 22 are formed in shapes that can be engaged with each other, and form a hollow cylindrical body by engaging with each other. Further, the outer surfaces of the upper part 21 and the lower part 22 are provided with irregularities functioning as heat sinks and heat radiating fins for increasing the heat radiation efficiency of the photoelectric conversion parts and electronic parts mounted on the substrate 40. Yes. Further, the engaging part between the upper part 21 and the lower part 22 has a labyrinth structure in which the engaging parts are engaged with each other without any gap in order to improve the shielding performance of electromagnetic noise. The material of the upper part 21 and the lower part 22 is not particularly limited as long as it is a material excellent in electromagnetic noise shielding performance and thermal conductivity, but an aluminum alloy or the like is preferably used as a material excellent in these characteristics. It is done.

  The cable protection component 25 is attached to the outside of the connection end portion of the cable 101 with the cable module 10 to protect the connection end portion. Similarly to the cable protection component 25, the cable protection component 26 is attached to the outside of the connection end portion of the cable 102 with the cable module 10 to protect the connection end portion. In this example, these cable protection parts 25 and 26 are provided with flanges at their ends, and these flanges are fitted into engagement grooves provided at the longitudinal ends of the upper part 21 or the lower part 22. As a result, the upper part 21 and the lower part 22 are fixed.

  The end covers 23 and 24 are components that cover the outside of the cable protection components 25 and 26, and are fixed to the longitudinal ends of the upper component 21 and the lower component 22. The materials of the end covers 23 and 24 and the cable protection components 25 and 26 are not particularly limited as long as they have a certain rigidity, but are the same as the upper component 21 and the lower component 22 in terms of rigidity and weight reduction. An aluminum alloy or the like is preferably used.

  The board 40 is arranged inside the casing, and has a plate-like circuit board fixed to the lower part 22 constituting the casing, an optical fiber connection portion 43 mounted on the circuit board, and a photoelectric circuit. It is composed of conversion elements 41 and 42 and electronic components such as a driving IC that drives the photoelectric conversion elements 41 and 42. In the following description, “substrate 40” substantially refers to the circuit board. Although not shown, electronic components such as a connector to which the signal line 113 included in the cable 102 is connected are mounted on the lower surface of the substrate 40.

  The photoelectric conversion element 41 is provided on the upper surface of the substrate 40, and the photoelectric conversion element 42 is provided on the lower surface of the substrate 40. Moreover, the optical fiber connection part 43 is provided corresponding to each of the photoelectric conversion elements 41 and 42, and connects a plurality of optical fiber cores (not shown) included in the cable 101 to the photoelectric conversion elements 41 and 42. It is made up of ferrules and sleeves.

  The photoelectric conversion elements 41 and 42 include a plurality of photodiodes (PD: Photo Diode) provided corresponding to each of the plurality of optical fiber core wires. Each of the plurality of photodiodes converts an optical signal transmitted through the optical fiber core wire into an electric signal corresponding to its intensity (amplitude). In addition, when the optical signal transmitted through the optical fiber core includes, for example, a plurality of types of optical signals corresponding to a wavelength division multiplexing (WDM) transmission system, the photoelectric conversion elements 41 and 42 further perform wavelength division. Including equipment. Further, the photoelectric conversion elements 41 and 42 may further include a signal amplifier circuit and the like.

  Here, the photoelectric conversion elements 41 and 42 are an example of a heating element disposed on the substrate 40, and generate heat when an optical signal is converted into an electrical signal. However, the generated heat can be efficiently radiated from the upper part 21 or the lower part 22 to the outside through the partition walls 61 and 62 and the protrusions 51 and 52 as described later.

  As shown in FIGS. 3 to 5, the protrusions 51 and 52 protrude from the inner surfaces of the upper part 21 and the lower part 22 toward the substrate 40. More specifically, the protrusion 51 is provided integrally with the upper part 21 constituting the casing, and the boss 51a protrudes downward from the inner surface of the upper part 21 and the tip of the boss 51a ( A heat-dissipating sheet 51b attached to the lower end portion, and is opposed to the surface (upper surface) of the photoelectric conversion element 41 mounted on the upper surface of the substrate 40. And the lower surface (surface on the opposite side to the boss | hub 51a) of the thermal radiation sheet 51b is contact | abutting with a part of partition 61 fixed to the upper surface of the photoelectric conversion element 41. FIG. Therefore, the protrusion 51 is indirectly in contact with the photoelectric conversion element 41 through the heat dissipation sheet 51 b and the partition wall 61.

  On the other hand, the protrusion 52 is provided integrally with the lower part 22 constituting the casing, and the boss 52a protrudes upward from the inner surface of the lower part 22 and the tip end (upper end) of the boss 52a. ), And is opposed to the surface (lower surface) of the photoelectric conversion element 42 mounted on the lower surface of the substrate 40. And the upper surface (surface on the opposite side to the boss | hub 52a) of the thermal radiation sheet 52b is contact | abutting with a part of partition 62 fixed to the lower surface of the photoelectric conversion element 42. FIG. Therefore, the protrusion 52 is in indirect contact with the photoelectric conversion element 42 through the heat dissipation sheet 52 b and the partition wall 62.

  Here, the material of the bosses 51a and 52a is not particularly limited as long as it is a material having excellent thermal conductivity. However, the boss 51a is integrally formed with the upper part 21 and the boss 52a is integrally formed with the same material. It is preferable. In addition, for the heat radiation sheets 51b and 52b, materials having excellent adhesion and thermal conductivity with the bosses 51a and 52a and the partition walls 61 and 62, such as silicone rubber, are preferably used. If there is, it is not limited to this. Silicone grease or the like may be used in place of the heat dissipation sheets 51b and 52b.

  Thus, since the protrusions 51 and 52 are indirectly in contact with the substrate 40 via other members such as the heat radiation sheets 51b and 52b and the partition walls 61 and 62, the cable module 10 of the present example has a heat dissipation property. Excellent. On the other hand, the protrusions 51 and 52 may be in direct contact with the substrate 40 without using other members, and can be appropriately changed according to the design of the module.

  By the way, as described above, the cable module 10 receives the optical signals transmitted through the plurality of optical fiber cores included in the cable 101 by the substrate 40 and converts them into electrical signals, and then the signals included in the cable 102. Provided for output to line 113. However, the cable 101 also includes wiring provided for purposes other than signal transmission and signal lines such as optical fibers that transmit signals corresponding to channels that are not subjected to photoelectric conversion in the cable module 10. Such wiring and signal lines pass through the inside of the casing of the cable module 10 and are included in the cable 102 as they are. In this example, the feeder lines 111 and 112 correspond to this, and the connection between the cable 101 and the cable module 10 is performed on the board 40 so as to avoid electronic components such as the photoelectric conversion elements 41 and 42 mounted on the board 40. To the connecting portion between the cable 102 and the cable module 10.

  In the cable module 10, a partition wall 61 is provided so as to separate the position where the power supply lines 111 and 112 pass on the substrate 40 and the protruding portion 51. As shown in FIGS. 4 and 5, the partition wall 61 includes a fixing portion 61a and wall portions 61b extending from both ends of the fixing portion 61a, and is formed of a material having excellent thermal conductivity such as metal. Yes.

  As shown in FIGS. 2 to 5, the fixing portion 61 a is fixed to the photoelectric conversion element 41 and the upper surface is in close contact with the heat radiation sheet 51 b at the tip of the protruding portion 51. That is, the fixing portion 61 a is sandwiched between the photoelectric conversion element 41 and the protruding portion 51.

  The wall portion 61b extends from both ends of the fixed portion 61a in a direction (diagonally upward) away from the protruding portion 51. That is, the wall portion 61 b is disposed so as to be inclined outward with respect to the protruding portion 51. And the protrusion part 51 is distribute | arranged to the space between the substantially opposing inner surfaces in the two wall parts 61b which comprise the partition 61, as shown in FIG. 5, and the feeder lines 111 and 112 are each of the wall part 61b. It is arranged in a space between the outer surface and the upper surface of the substrate 40. Therefore, the wall 61b separates the arrangement space of the protrusion 51 including the mounting direction of the protrusion 51 and the space through which the feeder lines 111 and 112 are passed. Thus, in the cable module 10 of the present example, the wall portion 61b extends from both ends of the fixed portion 61a in the direction away from the protruding portion 51. For example, the cable module 10 is assembled by the assembling method according to the following procedure. Thus, it is possible to reliably prevent the wiring from entering between the protruding portion 51 and the substrate 40.

<Assembly Method of Cable Module 10>
Next, a method for assembling the cable module 10 of this example will be described with reference to the flowchart shown in FIG.

  In this assembling method, first, the partition wall 62 is arranged so that the heat radiation sheet 52b at the upper end of the protruding portion 52 of the lower part 22 and the fixing portion 62a are in contact (step S100). Next, the board | substrate 40 is attached to the engagement recessed part provided in the upper end part both sides of the lower part 22 (step S110). Then, the feeder lines 111 and 112 are passed through the lower part 22 (step S120). In this example, the feeder lines 111 and 112 are passed along the longitudinal direction of the lower component 22 on both sides of the photoelectric conversion element 41 on the substrate 40 attached inside the lower component 22.

  Next, the partition wall 61 is positioned as shown in FIG. 5 (fixed position) so that the power supply lines 111 and 112 do not enter the arrangement space of the protruding portion 51 (so that the power supply lines 111 and 112 are pushed out from the arrangement space of the protruding portion 51). To the fixed position (step S130). More specifically, the partition wall 61 with the fixing portion 61 a down is moved downward from the upper side of the photoelectric conversion element 41 until the lower surface of the fixing portion 61 a contacts the upper surface of the photoelectric conversion element 41. At this time, the wall portion 61 b is disposed so as to be inclined in a direction away from the protruding portion 51 (outward with respect to the protruding portion 51). Finally, the upper part 21 is attached and the fixing part 61a of the partition wall 61 is pressed from above by the protruding part 51 of the upper part 21, thereby causing the protruding part 51 to contact the substrate 40 indirectly (step S140). As described above, the cable module 10 is assembled.

  By assembling the cable module 10 by the above assembly method, when the power supply lines 111 and 112 are passed, a part of the power supply lines 111 and 112 is lifted from the substrate 40 at a position near the photoelectric conversion element 41 and Even when the partition wall 61 is attached, even when the partition wall 61 is installed, the power supply lines 111 and 112 are outside the placement space of the protruding portion 51 (photoelectric conversion element 41) by the wall portion 61b extending obliquely upward (outside) from the fixing portion 61a. On both sides).

  Therefore, since it is possible to reliably and easily prevent the feeding lines 111 and 112 from entering the arrangement space of the projecting portion 51 between the wall portions 61b during the assembly, when attaching the upper component 21 to the lower component 22, there is a special case. Even if care is not taken, there is no possibility that the feeder lines 111 and 112 are sandwiched between the protruding portion 51 and the photoelectric conversion element 41. Therefore, assembly of the cable module 10 is facilitated.

  In the cable module 10 of this example, the shape of the wall 61b in the partition wall 61 and the fixing position of the partition wall 61 are not limited to the above example. For example, the wall part 61b having a shape corresponding to the side surface of the projecting part 51 is provided with the partition wall 61 in which the wall part 61b is disposed at substantially the same interval as the width of the projecting part 51 (the horizontal length in FIG. 5). It may be fixed to the photoelectric conversion element 41 so as to extend along the outer edge of the arrangement space. In other words, in this example, a substantially rectangular shape composed of a pair of wall portions 61b arranged opposite to each other in parallel with the width of the protruding portion 51 and a fixing portion 61a extending perpendicular to the wall portion 61b. The U-shaped partition wall 61 may be fixed to the photoelectric conversion element 41 such that the wall portion 61 b is disposed so as to surround the arrangement space of the protruding portion 51.

  Thereby, since the wall part 61b can be arrange | positioned with the minimum space | interval which does not interfere with the attachment of the protrusion part 51, for example, after installing the partition wall 61 as mentioned above, photoelectric conversion in the housing | casing of the cable module 10 is carried out. When assembling the cable module 10 by the procedure of passing the power supply lines 111 and 112 on both sides of the element 41, the following effects are produced. That is, since the wall portion 61b has the minimum interval as described above, the power supply lines 111 and 112 enter the arrangement space of the protruding portion 51 between the wall portions 61b when the power supply lines 111 and 112 are attached. Can be prevented more reliably. Therefore, there is no possibility that the feeder lines 111 and 112 are sandwiched between the projecting portion 51 and the photoelectric conversion element 41 without paying special attention when the upper part 21 is attached to the lower part 22 thereafter. . Therefore, the module can be easily assembled.

  The cable module 10 includes a fixed portion 62a and wall portions 62b extending obliquely downward from both ends of the fixed portion 62a on the lower side of the substrate 40, and has excellent thermal conductivity like the partition wall 61. A partition wall 62 made of a material is provided. As shown in FIG. 5, the projecting portion 52 is disposed in a space between the substantially opposed inner surfaces of the two wall portions 62 b constituting the partition wall 62. Therefore, it is possible to pass the wiring such as a power supply line through the space between the outer surface of each wall portion 62b and the lower surface of the substrate 40, and also when performing the operation of passing the wiring through this space as described above. It is possible to reliably and easily prevent the wiring from entering the arrangement space of the protruding portion 52 by mistake.

  Further, in the cable module 10, the photoelectric conversion elements 41 and 42 are both upper parts through the partition walls 61 and 62 and the protrusions 51 and 52 formed of a material having excellent thermal conductivity as described above. 21 or indirect contact with the lower part 22. Therefore, the heat generated from the photoelectric conversion elements 41 and 42 can be efficiently radiated from the upper part 21 or the lower part 22 to the outside.

  Instead of the protrusions 51 and 52, or in addition to the protrusions 51 and 52, protrusions that directly contact the upper surface and the lower surface of the substrate 40 may be provided on the inner surfaces of the upper part 21 and the lower part 22. Thereby, the heat generated in the substrate 40 or the heat transferred from the photoelectric conversion elements 41 and 42 to the substrate 40 can be efficiently radiated from the upper component 21 or the lower component 22 to the outside.

<Configuration of cable module 11>
FIG. 7 is a cross-sectional view corresponding to FIG. 5 of a cable module 11 according to another example of the embodiment of the present invention. In the description of the cable module 11, the same components as those of the cable module 10 described with reference to FIGS. 1 to 6 are denoted by the same reference numerals and description thereof is omitted.

  The cable module 11 includes partition walls 63 and 64 in place of the partition walls 61 and 62 arranged between the photoelectric conversion elements 41 and 42 and the protruding portions 51 and 52 in the cable module 10. That is, in the cable module 11, the photoelectric conversion elements 41 and 42 and the projecting portions 51 and 52 are in contact with each other without a partition.

  The partition wall 63 includes a fixing portion 63a fixed to one side of the upper surface of the substrate 40 sandwiching the photoelectric conversion element 41 and the protruding portion 51, and a wall portion 63b extending obliquely upward from one end of the fixing portion 63a. The partition wall 64 includes a fixed portion 64a fixed to the other side of the upper surface of the substrate 40 between the photoelectric conversion element 41 and the protruding portion 51, and a wall portion 64b extending obliquely upward from one end of the fixed portion 64a. Including.

  As shown in FIG. 7, the wall portions 63 b and 64 b extend from the ends of the fixing portions 63 a and 64 a near the protruding portion 51 in a direction away from the protruding portion 51 (upwardly obliquely). And the protrusion part 51 is distribute | arranged to the space between the wall part 63b and the wall part 64b. In addition, the power supply lines 111 and 112 are passed through a space on the opposite side to the protruding portion 51 when viewed from the wall portions 63b and 64b.

<Assembly method of cable module 11>
Next, a method for assembling the cable module 11 of this example will be described with reference to the flowchart shown in FIG.

  In this assembling method, first, the substrate 40 is attached to the engaging recesses provided on both sides of the upper end portion of the lower part 22 (step S200). Next, the partition walls 63 and 64 are arranged so that the space through which the feeder lines 111 and 112 on the substrate 40 pass and the arrangement space of the protruding portion 51 are separated by the wall portions 63b and 64b (step S210). At this time, the wall portions 63b and 64b are disposed so as to be inclined in a direction away from the protruding portion 51 (outward with respect to the protruding portion 51).

  Next, the feeder lines 111 and 112 are passed through the lower part 22 (step S220). In this example, the arrangement space of the protruding portion 51 on the substrate 40 attached to the inside of the lower part 22 and a different side (opposite side) across the walls 63b and 64b, that is, outside the walls 63b and 64b, The feeder lines 111 and 112 are passed along the longitudinal direction of the side part 22. Finally, the upper part 21 is attached, and the protrusion 51 of the upper part 21 is brought into direct contact with the substrate 40 (step S230). As described above, the cable module 11 is assembled.

  By assembling the cable module 11 by the above assembling method, even when a part of the power supply lines 111 and 112 are lifted from the substrate 40 when the power supply lines 111 and 112 are passed, the lifted power supply lines 111 and 112 protrude. It is difficult to enter the arrangement space of the part 51. In addition, since the work of passing the power supply lines 111 and 112 is performed after the partition walls 63 and 64 are attached to the upper surface of the substrate 40, a mistake that causes the power supply lines 111 and 112 to pass through the arrangement space of the protruding portion 51 by mistake. Is unlikely to occur.

  Therefore, there is no possibility that the feeder lines 111 and 112 are sandwiched between the projecting portion 51 and the photoelectric conversion element 41 without paying special attention when the upper part 21 is attached to the lower part 22 thereafter. Assembling of the module becomes easy.

  In the cable module 11 of this example, the partition walls 63 and 64 are formed of a material having excellent thermal conductivity, like the partition walls 61 and 62 of the cable module 10. Therefore, the partition walls 63 and 64 also function as heat radiating fins that radiate heat generated in the substrate 40 and heat transmitted from the photoelectric conversion elements 41 and 42 to the substrate 40.

  In the cable module 11, the partition walls 63 and 64 are provided only on the upper surface side of the substrate 40. However, in the cable module 11, the feeder lines 111 and 112 are passed only on the upper surface side of the substrate 40. For this reason, when wiring such as a power supply line is passed through the lower surface side of the substrate 40, a partition wall similar to the partition walls 63 and 64 is provided on the lower surface side of the substrate 40 so as to sandwich the protruding portion 52.

<Configuration of Cable Module 12>
FIG. 9 is a cross-sectional view corresponding to FIG. 5 of a cable module 12 according to still another example of the embodiment of the present invention. In the description of the cable module 12, the same components as those of the cable modules 10 and 11 described with reference to FIGS. 1 to 8 are denoted by the same reference numerals and description thereof is omitted.

  The cable module 12 includes a partition wall 65 provided integrally with the lower part 22. The partition wall 65 includes a fixed portion 65a and wall portions 65b extending upward from both ends of the fixed portion 65a.

  The fixing portion 65a is integrally formed with the lower part 22 at the position where the boss 52a is provided in the cable modules 10 and 11 described with reference to FIGS. 1 to 8, and similarly to the boss 52a, Projecting from the inner surface of the lower part 22 toward the lower surface of the substrate 40. It is in contact with the photoelectric conversion element 42 mounted on the lower surface of the substrate 40 via the heat dissipation sheet 52b disposed on the end surface (upper surface).

  As shown in FIG. 9, the wall portion 65 b extends from the both ends of the fixing portion 65 a through the through hole provided in the substrate 40 to the opposite side, and is provided on the opposite side across the substrate 40. The protrusion 51 extends along both side surfaces. That is, in this example, an arrangement space for the protruding portion 51 is formed between the two wall portions 65b extending through the substrate 40, and the feeder lines 111 and 112 are passed outside the respective wall portions 65b.

  In addition, although the flowchart of an assembly method is abbreviate | omitted, the module 12 for cables is assembled as follows, for example. That is, first, the wall portion 65 b of the partition wall 65 is inserted into the through hole of the substrate 40 so that the wall portion 65 b extends along both side surfaces (outer edges) of the arrangement space of the protruding portion 51. Fix it. Next, the feeders 111 and 112 are passed through different sides across the space where the protrusion 51 is arranged and the wall 65b.

  By assembling the cable module 12 by such a method, the gap between the both side surfaces of the projecting portion 51 and the wall portion 65b is very narrow. Therefore, when the power supply lines 111 and 112 are passed, It is possible to reliably prevent the protrusion 51 from entering the space from the gap. Therefore, there is no possibility that the feeder lines 111 and 112 are sandwiched between the projecting portion 51 and the photoelectric conversion element 41 without paying special attention when the upper part 21 is attached to the lower part 22 thereafter. Assembling of the module becomes easy.

  Further, since the partition wall 65 is formed of a material having excellent thermal conductivity, the heat generated from the substrate 40 and the photoelectric conversion element 42 can be efficiently radiated from the lower part 22 to the outside. Further, the partition wall 65 may be provided separately from the lower part 22 and attached to the lower part 22. However, the number of parts can be reduced by forming the partition wall 65 integrally with the lower part 22 as in this example. .

  In the above, examples of the embodiments of the cable module and the assembling method thereof according to the present invention have been described. Naturally, any possible form is included.

  For example, each of the cable modules 10, 11, and 12 according to each example of the above embodiment is a photoelectric conversion module that converts an optical signal transmitted through the cable 101 into an electrical signal and outputs the electrical signal to the cable 102. The present invention can also be applied to a cable module that converts an electrical signal into an optical signal. In addition, when the present invention is applied to a cable module that converts an electrical signal into an optical signal, a VCSEL (Vertical Cavity Surface Emitting Laser) is used as a light source instead of the photoelectric conversion elements 41 and 42 described above. An electro-optical conversion element is arranged.
