Description

  The present invention relates to an optical module package in which a fiber unit in which an optical waveguide device and an optical fiber are connected is accommodated in a housing.

  2. Description of the Related Art Conventionally, an optical module package in which an optical waveguide device in which a plurality of branched optical waveguides are formed and an optical fiber are connected and accommodated in a housing is known.

  Conventionally, the optical module package has a problem that the adhesive at the connection portion between the optical waveguide and the optical fiber absorbs moisture, thereby reducing the adhesive strength between the optical waveguide and the optical fiber.

  In order to solve such problems, conventionally, when manufacturing an optical module package, a fiber unit in which an optical waveguide device and an optical fiber are connected is accommodated in the housing, and the fiber unit is accommodated using an adhesive or resin. The idea of fixing to the above has been known (see, for example, Patent Document 1, Patent Document 2, Patent Document 3, and Patent Document 4).

Japanese Patent Laid-Open No. 7-92342 JP-A-8-94875 JP 2006-30552 A JP-A 63-205617 Japanese Patent Laid-Open No. 10-206681

  However, in the case of the optical module package disclosed in each of the above patent documents, since the fiber unit is fixed to the housing using an adhesive or resin, the following problems have not been solved.

  In general, the adhesive is often expensive. In addition, when an adhesive is used, it is necessary to pay close attention in order to prevent the optical module package from adhering to other parts in the process of manufacturing the optical module package, and the adhesive is applied to the member and then cured. A process is also required.

  In particular, when the fiber unit is to be fixed to the housing using an adhesive, the adhesive must be injected into the housing. At the time of the injection or the like, an adhesive may be attached to an extra portion of the housing, and it takes time and effort to avoid it.

  Moreover, when using resin, since the process which hardens | cures after filling in a housing is required, there existed a subject that it took an effort and time to manufacture.

  Therefore, the optical module package having a structure in which the fiber unit is fixed to the housing using an adhesive or a resin has a problem that it takes time and labor to manufacture.

  On the other hand, in order to fix the fiber unit in the housing, there is an idea of using a different spacer.

  However, in this case as well, since the spacer must be fixed to the housing using an adhesive or resin, the problem that it takes time and labor to manufacture cannot be solved.

  Furthermore, the optical module package disclosed in Patent Documents 1 to 4 has a structure in which an optical fiber is inserted into a tube-like member or insertion hole provided in the housing. For this reason, the optical module package according to these prior arts requires more time and effort to manufacture because the optical fiber insertion work is unavoidable during the manufacturing process.

  In this regard, the optical module package disclosed in Patent Document 5 can eliminate the need to insert an optical fiber through a tube-like member or the like.

  However, in the case of this optical module package, after housing the fiber unit in the housing, it is necessary to fill the housing with a plurality of types of resins. In addition, each time the resin is filled, a process for curing the resin must be obtained, so that the manufacturing process takes time and time.

  As described above, in each of the above conventional techniques, since the fiber unit is fixed to the housing using an adhesive or a resin, it is difficult to reduce labor and time required for manufacturing.

  Accordingly, the present invention has been made to solve the above problems, and in an optical module package in which an optical waveguide device and an optical fiber are connected and accommodated in the housing, the fiber unit is a housing using an adhesive or a resin.

First embodiment (structure of optical module package)
First, the structure of the optical module package 200 according to the first embodiment of the present invention will be described with reference to FIGS. Here, FIG. 1 is an exploded perspective view showing the optical module package 200 according to the first embodiment of the present invention, and FIG. 2 is a cross-sectional view of the housing body 1 taken along the longitudinal direction at the center in the short direction. FIG. 3 is a perspective view showing a main part of the housing main body 1 partially cut away. FIG. 4 is a front view showing a state in which the first and second holding members 10 and 30 are accommodated in the housing body 1, and FIG. 5 shows the first and second holding members 10 and 30 in a state in which the fiber unit 9 is accommodated. It is a perspective view shown. FIG. 6 is a side view of the optical module package 200 before mounting the cover body shown by cutting the housing main body 1, and FIG. 7 is a perspective view of the optical module package 200 shown by partially cutting the housing main body 1 and the cover body 2. FIG.

  The optical module package 200 includes a housing 1A having a housing body 1 and a cover body 2, a fiber unit 9, a first holding member 10, and a second holding member 30.

  In the optical module package 200, the two bottom locking projections 4 and 4 of the housing body 1 lock the side surfaces 10a and 10b of the first holding member 10, and the four wall locking projections 3, 3, 3, and 3 The side surfaces 10c, 10d, 30c, and 30d of the first and second holding members 10 and 30 are locked to restrict the movement of the first and second holding members 10 and 30. As a result, the optical module package 200 can be manufactured without fixing the fiber unit 9 to the housing 1A using an adhesive or a resin, and without inserting the optical fiber through the tube-like member. And time can be reduced.

  The housing body 1 is a U-shaped body that is made of metal or plastic and is generally U-shaped. As shown in FIG. 1, the housing main body 1 has a main body bottom portion 1 a and two main body wall portions 1 b and 1 c facing each other. The housing body 1 has a width (short width) in a direction along the short side inside the main body bottom 1a (a direction along the short side is also referred to as a “short direction”) set to L. The housing body 1 has a length that can accommodate the first and second holding members 10 and 30 and the optical fiber member 6 and the like of the fiber unit 9 with a predetermined length.

  And two bottom latching protrusions 4 and 4 are formed in the main body bottom 1a. Each bottom locking projection 4 is formed by locally projecting the main body bottom 1a from the outside toward the inside (see FIG. 2).

  The bottom locking protrusions 4 and 4 are arranged at positions aligned in a straight line along the direction along the longitudinal side of the housing body 1 (the direction along the longitudinal side is also referred to as “longitudinal direction”). The bottom locking projections 4 and 4 are substantially rectangular in plan view, and one of the four side portions (side portion 4a) faces each other. And the space | interval (space | interval along the longitudinal direction of the side part 4a) along the longitudinal direction of the bottom latching protrusions 4 and 4 is set to L4. This L4 corresponds to an arrangement interval L10 of the first holding member 10 described later.

  In the housing body 1, a space between the bottom locking protrusions 4, 4 is set as an accommodation space 16 for the first and second holding members 10, 30.

  Two wall locking projections 3 and 3 are formed on the main body wall portions 1b and 1c, respectively. Each wall locking projection 3 is formed by locally projecting the main body wall portions 1b and 1c from the outside toward the inside, similarly to the bottom locking projection 4.

  And in each of the main body wall parts 1b and 1c, the space | interval along the longitudinal direction of the two wall latching protrusions 3 and 3 is shorter than L4. Therefore, all the wall locking projections 3 are arranged in the accommodation space 16. Further, the height (the height from the main body bottom 1a) where the wall locking projections 3 and 3 are formed corresponds to the height of the portion where the first holding member 10 and the second connection portion 30 are in contact with each other. (See FIG. 4).

  Furthermore, the two wall locking projections 3 and 3 of the main body wall portion 1b and the two wall locking projections 3 and 3 of the main body wall portion 1c are arranged at positions facing each other. The interval along each short direction is L3 shown in FIG. This L3 corresponds to an arrangement interval W10 of the first holding member 10 which will be described later.

  The cover body 2 is a U-shaped body that is made of metal or plastic and is generally U-shaped, like the housing body 1. The cover body 2 has a top end portion 2a and two cover wall portions 2b and 2c facing each other, and is formed in a size that covers the housing body 1 from above. Further, the short width of the top end portion 2a is slightly larger than the short width L of the housing main body 1, and the cover wall portions 2b and 2c are formed in a size corresponding to the main body wall portions 1b and 1c of the housing main body 1. Yes. When the cover body 2 is placed on the housing body 1, as shown in FIG. 7, the cover wall portions 2b and 2c are brought into close contact with the body wall portions 1b and 1c of the housing body 1 from the outside, and the top end portion 2a The upper surface is covered.

  Two engagement protrusions 8 and 8 are formed on the cover wall portions 2b and 2c, respectively. Each engagement protrusion 8 is formed by causing the cover wall portions 2b and 2c to locally protrude from the outside toward the inside, similarly to the wall locking protrusion 3. Each engagement protrusion 8 is arranged at a position corresponding to each wall locking protrusion 3, and each shape also corresponds to each wall locking protrusion 3. When the cover body 2 is put on the housing body 1, the engagement protrusions 8 engage with the wall locking protrusions 3 from the outside.

  In the fiber unit 9, an optical fiber member 6 and a tape-shaped optical fiber member 7 are connected to the optical waveguide device 5, and these are united.

  As shown in FIG. 28, the optical waveguide device 5 has an optical waveguide substrate 5b on which an optical waveguide 5a is formed and fiber connectors 5c and 5d, and has a structure in which these are integrated.

  The optical waveguide 5a is formed so that a multi-core waveguide core branches from a single-core waveguide core. With the optical waveguide 5a, light incident from a single-core waveguide core can be evenly branched into a multi-core waveguide core.

  The fiber connector 5c is a connector to which a single-core optical fiber member 6 is connected, and is fixed to one end of the optical waveguide substrate 5b using an adhesive (not shown). The phi connector 5d is a connector to which the multi-core tape-like optical fiber member 7 is connected, and is fixed to the other end portion of the optical waveguide substrate 5b using an adhesive (not shown).

  The optical fiber member 6 has a structure in which the periphery of a single-core optical fiber is covered with a coating material. The tape-shaped optical fiber member 7 has a structure in which a plurality of (for example, eight) optical fibers arranged in parallel with each other are covered with a coating material to form a tape shape.

  Next, the first holding member 10 and the second holding member 30 will be described with reference mainly to FIG. Although the illustrated first and second holding members 10 and 30 have a common shape, the respective shapes may not be common. However, the first and second holding members 10 and 30 face each other while directly contacting the surfaces of projections 11, 13, 31, and 33, which will be described later (this state is also referred to as a direct facing state). The unit accommodating portion 15 described later is formed inside the side surfaces 10a, 10b, 10c, and 10d.

  The first and second holding members 10 and 30 constitute a unit holding member 103 according to the present invention. The first and second holding members 10 and 30 are formed using members having flexible rubber elasticity. For example, the first and second holding members 10 and 30 are chloroprene rubber, butyl rubber, chlorosulfonated polyethylene rubber, ethylene propylene rubber, acrylonitrile rubber, polysulfide rubber, natural rubber, which are used as industrial rubber packing materials. In addition, it can be formed using rubbers such as silicon rubber, fluorine rubber, polyacrylic rubber, and polyurethane rubber.

  The first holding member 10 is a thick plate-like body having a size that can be accommodated in the housing body 1. The first holding member 10 is surrounded by four side surfaces 10a, 10b, 10c, and 10d.

  The first holding member 10 has two convex portions 11 and 13 on both sides in the longitudinal direction, and a portion between them is a device receiving portion 12 that is recessed from the convex portions 11 and 13. The convex portion 11 has a narrow groove-shaped fiber receiving portion 11a formed on the surface 11c thereof. The fiber receiver 11 a is formed in a shape corresponding to the outer shape of the optical fiber member 6. The convex portion 13 has a wide groove-shaped fiber receiving portion 13a formed on the surface 13c thereof. The fiber receiving portion 13 a is formed in a shape corresponding to the outer shape of the tape-like optical fiber member 7. The device receiving portion 12 has a shape corresponding to the outer dimension of the optical waveguide device 5 (specifically, the dimension in the longitudinal direction is the same, but the thickness is almost half). End faces 11 b and 13 b facing the device receiving portion 12 are arranged at an interval corresponding to the length of the optical waveguide device 5.

In the first holding member 10, among the four side surfaces 10a, 10b, 10c, and 10d, the side surfaces 10a and 10b are opposed without intersecting , and the side surfaces 10c and 10d are opposed without intersecting . The side surfaces 10a and 10b correspond to the opposing surfaces in the present invention, and the side surfaces 10c and 10d also correspond to the opposing surfaces . Among these, since the side surfaces 10a and 10b are disposed apart along the longitudinal direction, they correspond to the longitudinal opposing surfaces in the present invention, and the side surfaces 10c and 10d are disposed apart along the lateral direction. This corresponds to a short-sided conflict .

  Further, as shown in FIG. 5, the arrangement interval of the side surfaces 10a and 10b is set to L10. The arrangement interval L10 is the length of the first holding member 10 and corresponds to the interval L4 between the bottom locking protrusions 4 and 4. Furthermore, the arrangement interval of the side surfaces 10c and 10d is set to W10. The arrangement interval W10 is the width of the first holding member 10 and corresponds to the interval L3 between the wall locking protrusions 3 and 3.

  The second holding member 30 is also a thick plate-like body similar to the first holding member 10. The second holding member 30 is surrounded by four side surfaces 30a, 30b, 30c, and 30d.

  The second holding member 30 has two convex portions 31 and 33 on both sides in the longitudinal direction, and a portion therebetween is a device receiving portion 32 similar to the device receiving portion 12. The convex portion 31 has a fiber receiving portion 31a similar to the fiber receiving portion 11a formed on the surface 31c thereof. The convex portion 33 has a fiber receiving portion 33a similar to the fiber receiving portion 13a formed on the surface 33c thereof.

  Since the second holding member 30 has the same shape as the first holding member 10, it has the same length and the same width as the first holding member 10.

  And the 1st holding member 10 and the 2nd holding member 30 are made to oppose, respectively making the surface of the convex part 11 and the convex part 31, and the convex part 13 and the convex part 33 contact each directly as shown in FIG. be able to. At this time, a space is formed in which the fiber receiving portions 11a and 31a, the device receiving portions 12 and 32, and the fiber receiving portions 13a and 33a are connected together. This space is the unit accommodating portion 15. The fiber receiving portions 11 a and 31 a have a shape corresponding to the optical fiber member 6, and the fiber receiving portions 13 a and 33 a have a shape corresponding to the tape-shaped optical fiber member 7. Further, the device receiving portions 12 and 32 have a shape corresponding to the outer dimension of the optical waveguide device 5. Therefore, the unit accommodating part 15 becomes a thing according to the external dimension of the fiber unit 9, and becomes a shape which can accommodate the fiber unit 9 in the state latched by the device receiving parts 12 and 32, etc. FIG.

  The pair of first and second holding members 10 and 30 and the fiber unit 9 as described above are accommodated in the housing main body 1, and the cover body 2 is covered from above, so that the optical module package 200 is configured.

  In this case, for example, first, the first holding member 10 is accommodated in the accommodation space 16 of the housing body 1, and then the fiber unit 9 is accommodated in the first holding member 10. At that time, the optical waveguide device 5 is fitted into the device receiving portion 12, and the optical fiber member 6 and the tape-like optical fiber member 7 are fitted into the fiber receiving portions 11a and 13a, respectively.

  Next, the second holding member 30 is overlapped with the first holding member 10 so that the surfaces 31c and 33c of the convex portions 31 and 33 are brought into direct contact with the surfaces 11c and 13c of the convex portions 11 and 13, respectively. . Then, since the unit accommodating portion 15 is formed by the first and second holding members 10 and 30, the fiber unit 9 is sandwiched between the first and second holding members 10 and 30 as shown in FIG. Can hold.

  Then, the cover body 2 is placed on the housing main body 1 and the engaging protrusions 8 and 8 are fitted into the wall locking protrusions 3 and 3 to engage them. Then, as shown in FIG. 7, the first and second holding members 10 and 30 are covered by the top end 2a. Further, the wall portions 2b and 2c are in close contact with the main body wall portions 1b and 1c of the housing main body 1 from the outside, so that the housing main body 1 and the cover body 2 are integrated. Thus, the optical module package 200 is completed.

  Unlike the above-described procedure, the second holding member 30 may be accommodated in the cover body 2 in advance. Alternatively, the fiber unit 9 may be held in advance by the first and second holding members 10 and 30 and may be accommodated together in the housing body 1.

(Operational effect of the optical module package 200)
As described above, in the optical module package 200, as shown in FIG. 5, the fiber unit 9 is held while being sandwiched between the first and second holding members 10 and 30, and is accommodated in the housing body 1 in that state. ing.

  The housing body 1 is generally U-shaped, and the fiber unit 9 can be directly inserted into and removed from an elongated space sandwiched between the body wall portions 1b and 1c. Therefore, the housing main body 1 can accommodate the fiber unit 9 in the housing main body 1 while extending along the axial direction without bending the optical fiber member 6 and the tape-shaped optical fiber member 7. Therefore, in the optical module package 200, when the fiber unit 9 is accommodated in the housing body 1, it is not necessary to insert the optical fiber member 6 and the like through the tube-shaped member. Can be reduced.

  Further, the first and second holding members 10 and 30 hold the fiber unit 9 while sandwiching it. In this case, the device receiving portions 12 and 32 of the first and second holding members 10 and 30 have shapes corresponding to the outer dimensions of the optical waveguide device 5, and the end surfaces 11 b and 13 b have the length of the optical waveguide device 5. It is arranged with a corresponding interval. Therefore, the end surfaces 11b and 13b abut against the optical waveguide device 5, and are sandwiched from both sides in the length direction. Thus, the movement of the optical waveguide device 5 can be restricted by the first and second holding members 10 and 30 so that the optical waveguide device 5 does not move in the longitudinal direction.

  A housing space 16 is secured in the housing body 1. As described above, the housing space 16 is a space sandwiched between the bottom locking protrusions 4 and 4. The interval along the longitudinal direction of the bottom locking projections 4 and 4 is L4, and this interval L4 corresponds to the arrangement interval L10 of the first holding member 10.

  Therefore, the first and second holding members 10 and 30 can be accommodated in the accommodation space 16, and the first holding member 10 abuts the side portions 4a and 4a of the bottom locking projections 4 and 4 on both sides in the longitudinal direction. Can be made. Further, all the wall locking projections 3 are arranged inside the accommodation space 16, and the interval L3 along the short direction of the wall locking projections 3, 3 is the arrangement interval W10 of the first holding member 10. It corresponds to. Therefore, the first holding member 10 can be brought into contact with the wall locking protrusions 3 and 3 on both sides in the short direction.

  Then, the first holding member 10 can be sandwiched from both sides in the longitudinal direction by the bottom locking projections 4 and 4, and the movement can be restricted so as not to move in the longitudinal direction. Further, the wall holding projections 3 and 3 can sandwich the first holding member 10 from both sides in the short direction, and the movement can be restricted so as not to move in the short direction. Moreover, since the height of the wall latching protrusions 3 and 3 corresponds to the height of the portion where the first holding member 10 and the second connecting portion 30 are in contact with each other, The movement can also be restricted so that the holding member 30 does not move in the short direction.

  Therefore, the optical module package 200 is manufactured by simply covering the cover body 2 after the fiber unit 9 and the first and second holding members 10 and 30 are accommodated in the housing body 1 as described above. Can do. Since the optical module package 200 does not need to fix the fiber unit 9 to the housing 1A using an adhesive or resin, it is possible to further reduce labor and time required for manufacturing.

  Furthermore, since the engagement protrusions 8 and 8 of the cover body 2 are fitted to the wall locking protrusions 3 and 3, the cover body 2 and the housing body 1 can be integrated without using an adhesive or resin. The time and effort required for this can be further reduced.

(Modification)
The first and second holding members 40 and 50 according to the modification will be described with reference to FIG. The first and second holding members 40 and 50 are different from the first and second holding members 10 and 30 in that they have device receiving portions 42 and 52 instead of the device receiving portions 12 and 32. ing.

  The device receiving portions 42 and 52 are different from the device receiving portions 12 and 32 in that they are recessed portions into which the optical waveguide device 5 is fitted. The device receiving portions 42 and 52 abut against the optical waveguide device 5 not only in the longitudinal direction but also from the short direction, and lock the optical waveguide device 5 from both the longitudinal direction and the short direction. Therefore, by using the first and second holding members 40 and 50, the movement of the optical waveguide device 5 is more reliably regulated, and the fiber unit 9 can be held more reliably.

  In the above description, as shown in FIG. 4, one wall locking projection 3 locks both the first and second holding members 10 and 30. On the other hand, although not shown, two wall locking projections 3 are formed along the height direction, and the first holding member 10 and the second holding member 30 are formed by the respective wall locking projections 3. Each may be locked. If it carries out like this, the intensity | strength of holding | maintenance of the 1st, 2nd holding members 10 and 30 by the housing 1A will improve.

  Furthermore, the interval L4 between the bottom locking protrusions 4 and 4 may be slightly larger than the arrangement interval L10 of the first holding member 10. As a result, a slight gap is created between the bottom locking projections 4, 4 and the first holding member 10, so that an increase in size due to thermal expansion of the first holding member 10 can be absorbed.

  Furthermore, the housing main body 1 and the cover body 2 have a wall locking projection 3 and an engagement projection 8 respectively. The housing body 1 and the cover body 2 have locking holes and engaging claws such as a locking hole 153 and an engaging claw 158, which will be described later, instead of having the wall locking protrusion 3 and the engaging protrusion 8, respectively. May be.

The shallow bottom portions 63a and 63a are disposed on both outer sides of the deep bottom portion 63b, and are formed shallower than the deep bottom portion 63b. Since the portion connecting the deep bottom portion 63b and the shallow bottom portions 63a and 63a is a stepped portion, the housing recess 63 has a step structure having such a step portion. Of the inner wall facing the receiving recess 63, the longitudinal inner walls 63bb and 63bb arranged along the longitudinal direction of the housing body 60 function as a locking portion that restricts the movement of the first holding member 70. have.

  Further, the housing main body 60 includes four main body engaging portions 64 including engaging protrusions 64a.

  Next, the first holding member 70 and the second holding member 90 will be described mainly with reference to FIG. The illustrated first holding member 70 and second holding member 90 have a common shape. However, both may have different shapes.

  In a state where the first and second holding members 70 and 90 face each other while directly contacting the surfaces of contact end portions 71, 72, 91, and 92 described later (this state is also referred to as a direct facing state). The unit housing portion 75 is formed by the device receiving portions 73 and 93 described later. As shown in FIG. 10, the unit accommodating portion 75 has a shape that can accommodate the fiber unit 89 in a state of being locked by the device receiving portions 73, 93 and the like.

  The 1st, 2nd holding members 70 and 90 are formed using the chloroprene rubber etc. which are used as an industrial rubber packing material similarly to the 1st and 2nd holding members 10 and 30. As shown in FIG.

  The first holding member 70 has two contact end portions 71 and 72 on both sides in the longitudinal direction, a portion between them is depressed more than the contact end portions 71 and 72, and the contact end portions 71 and 72 and the peripheral wall portion 70 d The device receiving unit 73 is surrounded.

  The contact end portion 71 is formed with a narrow groove-shaped fiber receiving portion 71a on the surface 71c thereof. The fiber receiving portion 71 a is formed in a shape corresponding to the outer shape of the optical fiber member 6. The contact end portion 72 has a wide groove-shaped fiber receiving portion 72a formed on the surface 72c thereof. The fiber receiving portion 72 a is formed in a shape corresponding to the outer shape of the tape-like optical fiber member 7.

  The device receiving portion 73 has a shape corresponding to the outer dimension of the optical waveguide device 80 (specifically, the dimension in the longitudinal direction is the same, but the thickness is almost half). The device receiving part 73 has a bottom part 73b and a locking convex part 73c arranged at the center in the length direction.

  Further, the back surface side of the device receiving portion 73 is a stepped convex portion 70e. End faces that are separated along the longitudinal direction of the stepped protrusion 70e are longitudinal end faces 73bb and 73bb. The step protrusion 70e is fitted into the housing recess 63 and has a shape corresponding to the step structure of the housing recess 63. In addition, the arrangement interval of the longitudinal end surfaces 73bb and 73bb corresponds to the arrangement interval of the longitudinal inner wall portions 63bb and 63bb, and the shape of each longitudinal end surface 73bb corresponds to the shape of the longitudinal inner wall portion 63bb.

  The second holding member 90 has two contact end portions 91 and 92 on both sides in the longitudinal direction, and a portion between them is a device receiving portion 93 that is recessed from the contact end portions 91 and 92. The contact end portion 91 has a fiber receiving portion 91a similar to the fiber receiving portion 71a formed on the surface 91c thereof. The contact end portion 92 has a fiber receiving portion 92a similar to the fiber receiving portion 72a formed on the surface 92c thereof. The device receiving part 93 has a shape common to the device receiving part 73, and has a step convex part 90e corresponding to the step convex part 70e.

  The first and second holding members 70 and 90 as described above can be opposed to each other while the surfaces of the contact end portion 71 and the contact end portion 91 and the contact end portion 72 and the contact end portion 92 are in direct contact with each other. . Then, as shown in detail in FIG. 10, the space where the fiber receiving portions 71 a and 91 a, the device receiving portions 73 and 93, and the fiber receiving portions 72 a and 92 a are connected together is the first and second holding members 70. , 90 is formed inside. This space is the unit accommodating portion 75.

  The fiber receiving portions 71 a and 91 a have a shape corresponding to the optical fiber member 6, and the fiber receiving portions 72 a and 92 a have a shape corresponding to the tape-shaped optical fiber member 7. The device receiving portions 73 and 93 both have a shape corresponding to the external dimensions of the optical waveguide device 80. Therefore, the unit accommodating part 75 formed by these has a shape that can accommodate the fiber unit 89 in a state of being locked by the device receiving parts 73, 93 and the like.

  As shown in FIG. 9, in the fiber unit 89, the optical fiber member 6 and the tape-like optical fiber member 7 are connected to the optical waveguide device 80, and these are united. The optical waveguide device 80 has an outer shape different from that of the optical waveguide device 5, but is otherwise the same.

  In the optical waveguide device 80, a recess 80b is formed between the flat end portions 80a and 80a. When the fiber unit 89 is accommodated in the unit accommodating portion 75, the contact ends 80 d and 80 d in the longitudinal direction of the flat end portions 80 a and 80 a abut against the device receiving portion 93. Directional movement is restricted. Further, the movement in the short direction is also restricted by the device receiver 93. Furthermore, since the concave portion 80b and the convex portion 80c on the back side are in contact with the engaging convex portions 93c and 73c, the optical waveguide device 80 is also restricted in vertical movement by the device receiving portions 73 and 93.

  The cover body 100 is different from the housing main body 60 in that the cover engaging portion 104 having the engaging hole 104a is provided instead of the main body engaging portion 64, but the other structure is the same as that of the housing main body 60. A tank-shaped body provided. However, the cover body 100 may have a different shape from the housing body 60 by changing the shape of the front side.

  The cover body 100 is formed with an accommodation recess 103 similar to the accommodation recess 63. The housing recess 103 is formed with a locking projection 103c similar to the locking projection 63c. The housing recess 103 has a formation in which the step protrusion 90e is fitted. Further, the cover body 100 is formed with a fiber receiving portion (not shown) similar to the fiber receiving portions 61a and 62a, and has a longitudinal inner wall portion similar to the longitudinal inner wall portions 63bb and 63bb.

(Operational effect of the optical module package 300)
As described above, in the optical module package 300, as shown in FIG. 10, the fiber unit 89 is held while being sandwiched between the first and second holding members 70 and 90, and in this state, the housing 106 (the housing main body 60 and the housing unit 60). Cover body 100).

  The housing body 60 and the cover body 100 have fiber receiving portions 61a and 62a and fiber receiving portions (not shown) similar to these on both sides in the lengthwise direction of the housing recesses 63 and 103, respectively. Therefore, in the optical module package 300, the fiber unit 89 can be accommodated in the housing 106 while the optical fiber member 6 and the like are stretched along the axial direction without being bent. Therefore, similarly to the optical module package 200, the optical module package 300 does not require the optical fiber member 6 or the like to be inserted into the tube-shaped member when the fiber unit 89 is accommodated in the housing 106, and therefore, the labor and time required for manufacturing are reduced. Can be reduced.

  In addition, since the first and second holding members 70 and 90 accommodate the fiber unit 89 in a locked state, the movement of the fiber unit 89 is restricted by the first and second holding members 70 and 90. The

  In addition, the longitudinal inner wall portions 63bb and 63bb of the housing main body 60 are in contact with the longitudinal end surfaces 73bb and 73bb of the first holding member 70 to lock them. A longitudinal inner wall portion (not shown) of the cover body 100 also abuts on and locks a longitudinal end surface similar to the longitudinal end surface 73bb of the second holding member 90. Therefore, not only can the movement of the optical waveguide device 80 be restricted by the first and second holding members 70 and 90, but also the housing 106 can prevent the first and second holding members 70 and 90 from moving in the longitudinal direction. The movement can also be regulated.

  Further, the step protrusion 70 e is fitted into the housing recess 63, and the step protrusion 90 e of the second holding member 90 is fitted into the housing recess 103 of the cover body 100. Further, the contact end portions 71 and 72 are fitted to the shallow bottom portions 63a and 63a without a gap, and similarly, the contact end portions 91 and 92 are fitted to a shallow bottom portion (not shown) of the cover body 100 without a gap. For this reason, the first and second holding members 70 and 90 are also restricted from moving in the short direction by the housing 106.

  Therefore, in the optical module package 300, the first holding member 70 is accommodated in the housing main body 60, the fiber unit 89 is accommodated, and the second holding member 90 is covered from above. It can be manufactured simply by mounting it on the housing body 60. Therefore, similarly to the optical module package 200, the optical module package 300 does not require the fiber unit 89 to be fixed to the housing 106 using an adhesive or a resin, so that labor and time required for manufacturing can be reduced.

  Further, by engaging the cover engaging portion 104 of the cover body 100 with the main body engaging portion 64, the cover body 100 and the housing main body 60 can be integrated without using an adhesive or resin. And time can be further reduced.

(Modification)
An optical module package 300A according to a modification will be described with reference to FIGS. Optical module package 300A is different from the optical module package 300, housing 106, first, instead of the second holding member 70, 90, that it has a housing 106A, first, second holding member 70A, the 90A Is different.

  The housing 106A has a housing body 60A and a cover body 100A. The housing main body 60A is different from the housing main body 60 in that flat end portions 61A and 62A are provided instead of the flat end portions 61 and 62. The flat end portions 61A and 62A differ from the flat end portions 61 and 62 in that they have fiber receiving portions 66 and 62b instead of the fiber receiving portions 61a and 62a, respectively, and the length in the longitudinal direction is longer. ing. The fiber receiver 66 is wider than the fiber receiver 61a. The fiber receiving portion 66 is connected to the shallow bottom portion 63a and is formed to have the same width as the shallow bottom portion 63a. The fiber receiving portion 62b is longer in the longitudinal direction than the fiber receiving portion 62a.

  The first holding member 70 </ b> A is different from the first holding member 70 in that it has contact end portions 71 </ b> A and 72 </ b> A instead of the contact end portions 71 and 72. The contact end portions 71A and 72A are longer in the longitudinal direction than the contact end portions 71 and 72. The contact end portion 71 </ b> A protrudes from the fiber receiving portion 66 while engaging the one shallow bottom portion 63 a and the fiber receiving portion 66. The contact end portion 72A protrudes from the fiber receiving portion 62b while engaging with the one shallow bottom portion 63a and the fiber receiving portion 62b. Further, the distance between both end portions of the contact end portions 71A and 72A is longer than the length in the longitudinal direction of the housing 60A.

  The first holding member 90A is different from the first holding member 90 in that the first holding member 90A has contact end portions 91A and 92A instead of the contact end portions 91 and 92. The contact end portions 91A and 92A are longer in the longitudinal direction than the contact end portions 91 and 92, and have a structure common to the contact end portions 71A and 72A.

  The cover body 100 </ b> A is different from the cover body 100 in that it has a fiber receiver 105 corresponding to the fiber receiver 66.

  Similarly to the optical module package 300, the optical module package 300A as described above is held while the fiber unit 89 is sandwiched between the first and second holding members 70A and 90A, and is accommodated in the housing 106A in that state. .

  And the space | interval of the both ends of contact end part 71A, 72A is longer than the length of the longitudinal direction of housing 60A. Therefore, when the first and second holding members 70A and 90A are accommodated in the housing body 60A and covered with the cover body 100A, as shown in FIGS. 13 and 14, the ends of the contact end portions 71A, 91A, 72A and 92A The portion protrudes outward from the housing main body 60A and the cover body 100A, and becomes an extended end portion 71B, 91B, 72B, 92B. In the optical module package 300A, the optical fiber member 6 and the tape-shaped optical fiber member 7 are fixed to the projecting end portions 71B, 91B, 72B, and 92B using an adhesive 107.

  In such an optical module package 300A as well, it is not necessary to fix the fiber unit 89 to the housing 106A using an adhesive or a resin, so that it is possible to further reduce labor and time required for manufacturing.

  In addition, in the optical module package 300A, since the optical fiber member 6 and the like are fixed to the overhanging end portion 71B and the like, the optical fiber member 6 and the like are unlikely to contact the housing 106A when the optical fiber member 6 and the like are bent. Become. Further, there is no possibility that the optical fiber member 6 and the like enter the gap between the first and second holding members 70A and 90A.

In place of the first and second holding members 70A and 90A , a holding member with a partially opened side surface, such as the first and second holding members 10 and 30, may be used.

Third Embodiment (Optical Module Package Structure)
First, the structure of the optical module package 400 according to the third embodiment of the present invention will be described with reference to FIGS. Here, FIG. 15 is an exploded perspective view showing an optical module package 400 according to the third embodiment of the present invention, and FIG. 16 is a cross-section when the optical module package 400 is cut along the longitudinal direction at the center in the short direction. 17 and 17 are perspective views of the optical module package 400. FIG.

  The optical module package 400 includes a housing 131 having a housing main body 110 and a cover body 130, a fiber unit 89, and first and second holding members 120 (120A and 120B).

  In the optical module package 400, the two inner inclined portions 113aa and 113aa of the housing main body 110 lock the first holding member 120A to restrict the movement of the first holding member 120A. As a result, the optical module package 400 can be manufactured without fixing the fiber unit 89 to the housing 131 using an adhesive or a resin, and without inserting the optical fiber through the tube-like member. And time can be reduced.

  Compared with the housing body 60, the housing body 110 has a housing recess 113 formed in place of the housing recess 63, and flat ends 111, 112 formed in place of the flat ends 61, 62. Is different.

  The housing recess 113 is different from the housing recess 63 in that it has shallow bottom portions 113a, 113a, a deep bottom portion 113b, and a locking projection 113c instead of the shallow bottom portions 63a, 63a, the deep bottom 63b, and the locking projection 63c. It is different. The shallow bottom portion 113a is different from the shallow bottom portion 63a in that a portion connected to the deep bottom portion 113b is an inner inclined portion 113aa. The inner inclined portion 113aa is not a step like the accommodating recess 63a, but an inclined surface that connects the shallow bottom portion 113a and the deep bottom portion 113b in a gentle downward inclined shape. The deep bottom portion 113b and the locking convex portion 113c are the same as the deep bottom portion 63b and the locking convex portion 63c, respectively.

  The flat end portions 111 and 112 are different from each other in that the length in the longitudinal direction is shorter than that of the flat end portions 61 and 62 and the fiber receiving portions 111a and 112a. The fiber receivers 111a and 112a are different from each other in that the length is shorter than the fiber receivers 61a and 62a.

  The cover body 130 is different from the housing main body 110 in that the cover engaging portion 104 is provided instead of the main body engaging portion 64, but the rest has a common structure. The cover body 130 has an accommodation recess 133 similar to the accommodation recess 113. The cover body 130 may have a shape different from that of the housing body 110 by changing the shape of the surface.

  As with the first and second holding members 70 and 90, the first and second holding members 120A and 120B are made of a member having flexible rubber elasticity such as chloroprene rubber used as an industrial rubber packing material. Is formed.

  The first and second holding members 120A and 120B are formed in a plate shape as illustrated. As described above, the first and second holding members 70 and 90 have shapes corresponding to the housing body 60 and the cover body 100, respectively. On the other hand, the first and second holding members 120A and 120B are plate-like members in an external force state where no external force is applied, but are deformed into shapes corresponding to the housing main body 110 and the cover body 130, respectively.

(Operational effect of the optical module package 400)
In the optical module package 400, the fiber unit 89 is held while being sandwiched between the first and second holding members 120A and 120B, and is accommodated in the housing 131 (the housing body 110 and the cover body 130) in that state.

  Similarly to the optical module package 300, the optical module package 400 can accommodate the fiber unit 89 in the housing main body 110 while extending the optical fiber member 6 and the like along the axial direction without bending. Therefore, similarly to the optical module package 300, the optical module package 400 can reduce labor and time required for manufacturing.

  The first and second holding members 120A and 120B are formed using a member having flexible rubber elasticity. Therefore, when the first and second holding members 120A and 120B are accommodated in the housing body 110 while sandwiching the fiber unit 89, and the cover body 130 is attached to the housing body 110, the first and second holding members 120A and 120B respectively correspond to the accommodating recesses 113 and 133. It closely contacts the fiber unit 89 while deforming.

  In this case, the movement of the fiber unit 89 is regulated by the first and second holding members 120A and 120B.

  In addition, with respect to the housing recess 113, the inner inclined portion 113aa comes into contact with the first holding member 120A and locks the first holding member 120A by friction. As for the accommodation recess 133, the inner inclined portion abuts against the second holding member 120 </ b> B, and the first holding member 120 </ b> B is locked by friction. Therefore, the movement can be restricted by the housing 131 so that the first and second holding members 120A, 120B do not move in the longitudinal direction.

  Further, when the first holding member 120A is fitted into the housing recess 113, the movement of the first holding member 120A in the short direction is also restricted. Similarly, when the second holding member 120B is fitted into the housing recess 133, the movement of the second holding member 120B in the short direction is also restricted.

  Therefore, the optical module package 400 accommodates the first holding member 120A in the housing main body 110, accommodates the fiber unit 89, and covers the second holding member 120B from above. It can be manufactured simply by mounting it on the housing body 110. Therefore, since the optical module package 400 does not need to fix the fiber unit 89 to the housing 131 using an adhesive or resin, as in the optical module package 300, the labor and time required for manufacturing can be further reduced. .

  In particular, the optical module package 400 has plate-like first and second holding members 120 </ b> A and 120 </ b> B, and therefore has an operational effect different from that of the optical module package 300.

  In the optical module package 300 described above, the first and second holding members 70 and 90 processed into a shape corresponding to the housing 106 need to be prepared in advance.

  However, in the optical module package 400, the first and second holding members 120 </ b> A and 120 </ b> B are plate-shaped, and it is not necessary to process them into a shape corresponding to the housing 131 in advance. Therefore, in the optical module package 400, labor and time required for manufacturing can be reduced as compared to the optical module package 300, and manufacturing cost can be reduced.

(Modification)
An optical module package 400A according to a modification will be described with reference to FIGS. Compared to the optical module package 400, the optical module package 400 </ b> A replaces the housing main body 110, the first and second holding members 120 </ b> A and 120 </ b> B, and the cover body 130 with the housing main body 110 </ b> A, the first and second holding members. 122A and 122B and the cover body 130A are different.

  The housing main body 110 </ b> A is different from the housing main body 110 in that flat end portions 111 </ b> A and 112 </ b> A are provided instead of the flat end portions 111 and 112. The flat end portions 111A and 112A differ from the flat end portions 111 and 112 in that they have fiber receiving portions 116 and 112b instead of the fiber receiving portions 111a and 112a, respectively, and the length in the longitudinal direction is longer. ing. The fiber receiver 116 is wider than the fiber receiver 111a. The fiber receiving portion 116 is connected to the shallow bottom portion 113a and is formed to have the same width as the shallow bottom portion 113a. The fiber receiving portion 112b is connected to the shallow bottom portion 113a and is formed to have the same width as the shallow bottom portion 113a.

  The first and second holding members 122A and 122B are different from the first and second holding members 120A and 120B in that the length in the longitudinal direction is longer. The longitudinal length of the first and second holding members 122A and 122B is longer than that of the housing 131A.

  The cover body 130 </ b> A is different from the cover body 130 in that it has a fiber receiving portion 135 corresponding to the fiber receiving portion 116 and is longer in the longitudinal direction.

  Also in the optical module package 400A as described above, as in the optical module package 400, the fiber unit 89 is held while being sandwiched between the first and second holding members 122A and 122B, and is accommodated in the housing 131A in that state. .

  Since the longitudinal length of the first and second holding members 122A and 122B is longer than that of the housing 131A, both longitudinal ends of the first and second holding members 122A and 122B are stretched from the housing 131A. put out. Therefore, as shown in FIGS. 19 and 20, the optical fiber member 6 and the tape-like optical fiber member 7 are fixed to the protruding end portion using an adhesive 136.

  In such an optical module package 400A as well, it is not necessary to fix the fiber unit 89 to the housing 131A using an adhesive or a resin, so that it is possible to reduce labor and time required for manufacturing.

  In addition, the optical module package 400A has the optical fiber member 6 and the like fixed to the projecting ends of the first and second holding members 122A and 122B. The fiber member 6 and the like are unlikely to contact the housing 131A. Further, there is no possibility that the optical fiber member 6 and the like enter the gap between the first and second holding members 122A and 122B.

  In the above-described housing 131, the housing recess 113 has the inner inclined portion 113aa, but it may have a step structure like the housing 60 instead of the inner inclined portion 113aa.

Fourth Embodiment (Optical Module Package Structure)
First, the structure of an optical module package 500 according to the fourth embodiment of the present invention will be described with reference to FIGS. Here, FIG. 21 is an exploded perspective view showing an optical module package 500 according to the fourth embodiment of the present invention, and FIG. 22 is a cross-section when the optical module package 500 is cut along the longitudinal direction at the center in the short direction. FIG. FIG. 23 is a perspective view showing the housing body 151 and the cover body 152 with a part thereof omitted. FIG. 24 is a front view showing the main part of the optical module package 500, and FIG. 25 is a perspective view of the same. FIG. 27 is a perspective view showing the first holding member 160.

  The optical module package 500 includes a housing 151A having a housing main body 151 and a cover body 152, a fiber unit 99, a first holding member 160, and a second holding member 170.

  In the optical module package 500, the bottom locking projection 154 of the housing main body 151 and the top end locking projection 159 of the cover body 152 lock the first holding member 160 and the second holding member 170, respectively. Regulate the movement of As a result, the optical module package 500 can be manufactured without fixing the fiber unit 99 to the housing 151A using an adhesive or a resin, and without inserting the optical fiber through the tube-like member. And time can be reduced.

  The housing main body 151 is a U-shaped body formed in a substantially U-shape similar to the housing main body 1 described above. The housing main body 151 is different from the housing main body 1 in that four bottom locking protrusions 154 are formed instead of the two bottom locking protrusions 4 and a locking hole 153 instead of the wall locking protrusion 3. Is different from the point where the alignment portion 181 is formed.

Each bottom locking projection 154 is formed by locally projecting the main body bottom 1a from the outside toward the inside. Unlike the bottom locking projections 4, the four bottom locking projections 154 are arranged at positions where they contact the bottom 160 e of the first holding member 160. Two of the four are arranged near both sides in the longitudinal direction of the main body bottom 1a , and the other two are arranged near the center in the longitudinal direction.

  The locking hole 153 is a through hole formed by cutting a part of the main body wall portions 1b and 1c into a rectangular shape. Three locking holes 153 are formed in each of the main body wall portions 1b and 1c. The respective locking holes 153 are arranged at substantially equal intervals along the longitudinal direction of the main body wall portions 1b and 1c.

  The alignment portion 181 is formed by locally projecting the main body wall portions 1b and 1c from the outside toward the inside, respectively. The alignment portion 181 is formed at a position corresponding to the reduced width portions 161f and 163f, which will be described later, near both longitudinal sides of the main body wall portions 1b and 1c.

  The cover body 152 is a U-shaped body formed in a substantially U shape similar to the cover body 2 described above. Compared with the cover body 2, the cover body 152 is aligned with a point where four top end locking projections 159 are formed, and an engagement claw 158 is formed instead of the engagement projection 8. The difference is that the portion 182 is formed.

  Similarly to the bottom locking projection 4 described above, the top end locking projection 159 is formed by locally projecting the top end portion 152a from the outside toward the inside. Further, all four are arranged at positions where they abut against the bottom 170 e of the second holding member 170. Two of the four are arranged near both sides in the longitudinal direction of the top end portion 152a, and the other two are arranged near the center in the longitudinal direction.

  In the optical module package 500, when the cover body 152 is put on the housing main body 151, the four top end locking projections 159 and the four bottom locking projections 154 are respectively formed from the top end portion 152a to the main body bottom portion 1a. Opposite along the up and down direction. In this way, in the optical module package 500, as shown in FIG. 22, a space 176 sandwiched between each top end locking projection 159 and each bottom locking projection 154 is secured, so this space 176 is the first, It is set as a storage space for the second holding members 160 and 170.

  Further, in the optical module package 500, the arrangement pattern of the four bottom locking protrusions 154 and the arrangement pattern of the four top end locking protrusions 159 are common. That is, the number of the bottom locking projections 154 and the number of the top end locking projections 159 are both equal, and the positional relationship (position on the bottom 1a) of each bottom locking projection 154 and each top end locking projection The positional relationship (position on the top end 152a) of the protrusion 159 is common. Accordingly, as shown in FIG. 23, each top end locking projection 159 is disposed at a position facing each bottom locking projection 154. Therefore, in the optical module package 500, when considering the straight line connecting each top end locking projection 159 and each bottom locking projection 154, this straight line is orthogonal to the main body bottom 1a and the top end 152a.

  Further, the housing main body 151 and the cover body 152 have an uneven arrangement structure regarding the arrangement of the bottom locking protrusions 154 and the top end locking protrusions 159. In the present embodiment, the uneven arrangement structure means that the bottom locking projections 154 and the top end locking projections 159 are not arranged at equal intervals on the main body bottom portion 1a and the top end portion 152a, respectively. , Meaning a structure that is biased to a specific position. In the case of the optical module package 500, the uneven arrangement structure is such that the bottom locking projections 154 and the like are positioned at positions corresponding to device locking portions 164a and 174a of first and second holding members 160 and 170 described later. However, this means a structure that is not disposed at a position corresponding to the connector locking portions 164b and 174b (see FIG. 22).

  In the optical module package 500, when the cover body 152 is placed on the housing main body 151, the top end portion 152a can be brought into contact with the open end portion 1e not connected to the main body bottom portion 1a of the main body wall portions 1b and 1c. At that time, the intervals along the vertical direction between the top end locking projections 159 and the corresponding bottom locking projections 154 (the interval between the most protruding portions) are the first and second holding members. The distance between the two bottom surfaces 160e and 170e at 160 and 170 is slightly smaller.

  The engaging claw 158 is a claw-shaped portion formed by making a substantially T-shaped cut in the cover wall portions 152b and 152c, folding the lower end portion thereof and folding the inside of the cut into the cover wall portions 152b and 152c. It is. Three engagement claws 158 are formed on the cover wall portions 152b and 152c, respectively, and are arranged at positions corresponding to the locking holes 153 of the housing main body 151. Each of them is formed in a size corresponding to the locking hole 153.

  The alignment portion 182 is formed by locally projecting the cover wall portions 152b and 152c from the outside toward the inside, respectively. The alignment portion 182 is disposed at a position corresponding to the alignment portion 181 of the housing main body 151, and each shape thereof also corresponds to the alignment portion 181. When the cover body 152 is put on the housing main body 151, each alignment portion 182 engages with each alignment portion 181 from the outside.

As shown in FIG. 27 in detail, the first holding member 160 has a point having convex portions 161 and 163 instead of the convex portions 11 and 13 and a device receiving portion 164 as compared with the first holding member 10. It is different in having it. A bottom surface 160e of the first holding member 160 corresponds to an opposing surface in the present invention together with a bottom surface 170e described later.

  The convex portion 161 has a fiber receiving portion 161a similar to the fiber receiving portion 11a formed on the surface thereof. The convex portion 161 has side surfaces 160c and 160d similar to the side surfaces 10c and 10d, and a portion connected to the device receiving portion 164 is a narrowed portion 161f having a narrow width.

  The convex portion 163 has a fiber receiving portion 163a similar to the fiber receiving portion 13a formed on the surface 163 thereof. The convex portion 163 has side surfaces 160c and 160d similar to the side surfaces 10c and 10d, and a portion connected to the device receiving portion 164 is a narrowed width portion 163f.

  The device receiving portion 164 includes a device locking projection 164a, a connector locking projection 164b, and a base portion 164c. The device locking projection 164a is formed on the base portion 164c at the center in the longitudinal direction, and is a portion that is somewhat thicker and wider than the base portion 164c. The connector locking protrusions 164b are formed one by one at positions on both sides of the device locking protrusions 164a on the base portion 164c, away from the device locking protrusions 164a. The base portion 164c is a thin band-shaped portion having a thickness that connects the reduced width portion 161f and the reduced width portion 163f.

  Compared with the second holding member 30, the second holding member 170 is different in that it has convex portions 171 and 173 instead of the convex portions 31 and 33 and a device receiving portion 174. .

  The convex portion 171 has a fiber receiving portion 171a similar to the fiber receiving portion 31a formed on the surface thereof. The convex portion 171 has side surfaces 170c and 170d similar to the side surfaces 30c and 30d, and a portion connected to the device receiving portion 174 is a narrowed portion 171f having a narrow width.

  The convex portion 173 has a fiber receiving portion 173a similar to the fiber receiving portion 33a formed on the surface thereof. The convex portion 173 has a side surface similar to the side surfaces 30c and 30d, and a portion connected to the device receiving portion 174 is a narrowed width portion 173f.

  The device receiving portion 174 has a device locking projection 174a, a connector locking projection 174b, and a base portion 174c. The device locking projection 174a is formed on the base portion 174c at the center in the longitudinal direction, and is a portion that is somewhat thicker and wider than the base portion 174c. The connector locking protrusions 174b are formed one by one at positions on both sides of the device locking protrusions 174a on the base portion 174c, away from the device locking protrusions 174a. The base portion 174c is a thin band-like portion having a thickness that connects the reduced width portion 171f and the reduced width portion 173f.

  The first and second holding members 160 and 170 can be opposed to each other while the convex portions 161 and 171 and the surfaces of the convex portions 163 and 173 are in direct contact with each other. Then, a space in which the fiber receiving portions 161a and 171a, the device receiving portions 164 and 174, and the fiber receiving portions 163a and 173a are connected together is formed. This space has a shape that can accommodate the fiber unit 99 in a state of being locked by the device receiving portions 164 and 174 and the like, like the unit accommodating portion 15.

  In the fiber unit 99, the optical fiber member 6 and the tape-shaped optical fiber member 7 are connected to the optical waveguide device 95, and these are united. The optical waveguide device 95 includes an optical waveguide substrate 95a and fiber connectors 95b and 95c, and has a structure in which these are integrated.

  The optical waveguide substrate 95a has an outer shape different from that of the optical waveguide substrate 5b, but an optical waveguide similar to that of the optical waveguide substrate 5b is formed. The optical waveguide substrate 95a is made of, for example, an alumina crystal. The fiber connectors 95b and 95c have different external shapes from the fiber connectors 5c and 5d, but are fixed to the optical waveguide substrate 95a using an adhesive (not shown) as in the fiber connectors 5c and 5d. The fiber connectors 95b and 95c are formed using, for example, quartz.

  The pair of first and second holding members 160 and 170 and the fiber unit 99 as described above are accommodated in the housing main body 151, and the cover body 152 is covered from above, so that the optical module package 500 is configured.

  In this case, for example, first, the first holding member 160 is accommodated in the housing main body 151, and then the fiber unit 99 is accommodated in the first holding member 160. Next, the second holding member 170 is overlapped with the first holding member 160, and the fiber unit 99 is held while being sandwiched between the first and second holding members 160 and 170. Then, the cover body 152 is placed on the housing main body 151, and the engaging claws 158 are fitted into the locking holes 153 to be engaged. Thus, the optical module package 500 is completed.

(Operational effect of the optical module package 500)
As described above, since the optical module package 500 holds the fiber unit 99 by the substantially U-shaped housing 151 </ b> A similar to the optical module package 200, it is required for manufacturing as with the optical module package 200. Time and effort can be reduced.

  Further, all the four bottom locking projections 154 are arranged at positions where they abut against the bottom 160e of the first holding member 160, and all the four top end locking projections 159 abut against the bottom 170e of the second holding member 160. Placed in position. Therefore, when the first and second holding members 160 and 170 are accommodated in the housing main body 151 and the cover body 152 is covered from above, the four bottom locking projections 154 and the top end locking projection 159 cause the first, The second holding members 160 and 170 can be held in a sandwiched manner.

  Therefore, in the optical module package 500, the first and second holding members 160 and 170 are prevented from moving not only in the longitudinal direction but also in the short direction by the bottom locking projection 154 and the top end locking projection 159. Can regulate the movement.

  Moreover, the distance between each top end locking projection 159 and each bottom locking projection 154 is slightly smaller than the spacing between the bottom surfaces 160e and 170e of the first and second holding members 160 and 170. Accordingly, the four bottom locking projections 154 and the top end locking projection 159 not only contact the bottom portions 160e and 170e but also press them while biting in. Therefore, the first and second holding members 160 and 170 are more It can be held firmly.

  Further, the optical waveguide substrate 95a and the fiber connectors 95b and 95c are separately locked by the device locking protrusions 164a and 174a of the device receiving portions 164 and 174 and the connector locking protrusions 164b and 174b. Since the optical waveguide substrate 95a and the fiber connectors 95b and 95c are formed of different materials, the size of expansion and contraction varies with temperature change.

  Accordingly, if a single plane connected to the optical waveguide substrate 95a and the fiber connectors 95b and 95c is brought into contact with the optical waveguide substrate 95a, distortion due to the difference in expansion and contraction occurs in the plane. There is a possibility that the force for holding the optical waveguide substrate 95a and the like may be reduced. In this regard, in the optical module package 500, the device locking protrusions 164a and 174a that are in contact with the optical waveguide substrate 95a and the connector locking protrusions 164b and 174b that are in contact with the fiber connectors 95b and 95c are formed at positions separated from each other. There is no risk of a decrease in holding force due to the difference in the size of expansion and contraction between the optical waveguide substrate 95a and the fiber connectors 95b and 95c.

  Moreover, the bottom locking projection 154 and the top end locking projection 159 are arranged in an unevenly arranged structure. The optical waveguide substrate 95a and the fiber connectors 95b and 95c have different sizes that expand and contract with a change in temperature. Therefore, if the bottom locking projection 154 and the top end locking projection 159 are formed at positions corresponding to the connector locking portions 164b and 174b, the bottom locking projection 154, the top end locking projection 159, and the first and second At the contact portions with the holding members 160 and 170, distortion due to the difference in the size of expansion and contraction is likely to occur, which may reduce the holding force of the housing main body 151 and the cover body 152.

  However, in the optical module package 500, since the bottom locking protrusion 154 and the top edge locking protrusion 159 are arranged in an unevenly arranged structure, there is no fear of the above-described decrease in holding force, and the housing body 151 and the cover body 152 Thus, the first and second holding members 160 and 170 can be reliably held.

  Furthermore, since the housing main body 151 and the cover body 152 have the alignment portions 181 and 182, respectively, the housing main body 151 and the cover body 152 can be easily and reliably aligned.

  The alignment portions 181 and 182 protrude inside the housing main body 151 and the cover body 152, respectively, but are formed at positions corresponding to the reduced width portions 161f and 163f. The members 160 and 170 are not contacted. When the alignment portions 181 and 182 are formed at positions where they contact the first and second holding members 160 and 170, the first and second holding members 160 and 170 of the first and second holding members 160 and 170 accompanying the pressing from the alignment portions 181 and 182 are formed. Due to the change in shape and the like, the force with which the bottom locking projection 154 and the top end locking projection 159 press the first and second holding members 160 and 170 changes, and the housing main body 151 and the cover body 152 change between the first and first. There is a possibility that the force for holding the two holding members 160 and 170 may decrease as a whole.

  However, in the optical module package 500, since the first and second holding members 160 and 170 are not pressed from the alignment portions 181 and 182, the holding force of the housing main body 151 and the cover body 152 may be reduced. Absent.

  And the arrangement pattern of each top end latching protrusion 159 and the arrangement pattern of each bottom latching protrusion 154 are common. Therefore, as shown in FIG. 24, the pressure f159 applied from each top end locking projection 159 to the second holding member 170 and the pressure f154 applied from each bottom locking projection 154 to the first holding member 160 are directions. Are opposite and are almost equal in size, going from the opposite direction to the same position. For this reason, the pressure f159 and the pressure f154 cancel each other and no moment is formed, so that the first and second holding members 160 and 170 can be more stably held by the housing 151A.

  As described above, the optical module package 500 does not need to fix the fiber unit 99 to the housing 151A using an adhesive or a resin, so that it is possible to reduce labor and time required for manufacturing.

(Modification)
An optical joule package 500A according to a modification will be described with reference to FIG. The optical joule package 500A is different from the optical joule package 500 in that it includes first and second holding members 160A and 170A instead of the first and second holding members 160 and 170. The first and second holding members 160A and 170A are formed so that the lengths of the convex portions 161, 163, 171, and 173 in the longitudinal direction are larger than those of the first and second holding members 160 and 170. The end portions of the first and second holding members 160A and 170A in the longitudinal direction protrude from the housing 151A.

  In the optical joule package 500A, the optical fiber member 6 and the like are fixed to the protruding portions of the first and second holding members 160A and 170A using an adhesive 167.

  In such an optical module package 500A as well, it is not necessary to fix the fiber unit 99 to the housing 151A using an adhesive or a resin, so that it is possible to further reduce labor and time required for manufacturing.

  In addition, in the optical module package 500A, like the optical module package 300A, when the optical fiber member 6 or the like is bent, the optical fiber member 6 or the like is difficult to contact the housing 151A, and the optical fiber member 6 or the like is the first, There is no possibility of entering the gap between the second holding members 160A and 170A.

  In the optical module packages 500 and 500A, the bottom locking protrusions 154 and the top edge locking protrusions 159 are formed four by four. The bottom locking protrusion 154 and the top edge locking protrusion 159 may be formed at least one each.

  The above description is the description of the embodiment of the present invention, and does not limit the apparatus and method of the present invention, and various modifications can be easily implemented. In addition, an apparatus or method configured by appropriately combining components, functions, features, or method steps in each embodiment is also included in the present invention.

  By applying the present invention, it is not necessary to fix the fiber unit to the housing using an adhesive or resin, and it becomes possible to manufacture an optical module package without inserting an optical fiber into a tube-shaped member. Can save time and effort. The present invention can be used for an optical module package in which an optical waveguide device and an optical fiber are connected and accommodated in a housing.
