The light emitting surfaces of the plurality of light emitting elements 30 or the light receiving surfaces of the plurality of light receiving elements 32 face upward. The light emitting element 30 is, for example, a VCSEL. The light receiving element 32 is, for example, a photodiode (PD).
　ＩＣ（図示せず）は、発光素子３０のＤｒｉｖｅｒ　ＩＣ及び受光素子３２のＲｅｃｅｉｖｅｒ　ＩＣであり、ガラス基板２４ａの下側の主面上に実装されている。回路基板２４は、図示しない配線及び複数の外部端子３６を更に有している。複数の外部端子３６は、ガラス基板２４ａの下側の主面の外縁に沿って並ぶように設けられている。配線は、ガラス基板２４ａの下側の主面に形成されており、複数の発光素子３０及び複数の受光素子３２とドライバＩＣと複数の外部端子３６とを電気的に接続している。 The IC (not shown) is a driver IC of the light emitting element 30 and a receiver IC of the light receiving element 32, and is mounted on the lower main surface of the glass substrate 24a. The circuit board 24 further includes wiring (not shown) and a plurality of external terminals 36. The plurality of external terminals 36 are provided so as to be arranged along the outer edge of the lower main surface of the glass substrate 24a.

　以上のように構成されたレセプタクルカバー２６は、図４Ｃに示すように、回路基板２４に接着部材３３ａ，３３ｂにより固定されることにより、レセプタクル本体２２に対する相対的な位置が固定されている。より詳細には、接着部材３３ａは、レセプタクルカバー２６において回路基板２４よりも上側に位置する部分（すなわち、左面部２６ａ）及び突出部２７ａに固着する。接着部材３３ｂは、レセプタクルカバー２６において回路基板２４よりも上側に位置する部分（すなわち、右面部２６ｄ）及び突出部２７ｂに固着する。更に、下面部２６ｃ，２６ｆ，２６ｉは、回路基板２４の厚みが薄くなっている領域に固定されている。これにより、回路基板２４の下面及び下面部２６ｃ，２６ｆ，２６ｉとは、実質的に１つの平面を構成している。 As shown in FIG. 4C, the receptacle cover 26 configured as described above is fixed to the circuit board 24 by adhesive members 33a and 33b, so that the relative position with respect to the receptacle body 22 is fixed.

The adhesive member 33b is fixed to the portion of the receptacle cover 26 that is located above the circuit board 24 (that is, the right surface portion 26d) and the protruding portion 27b. Furthermore, the lower surface portions 26c, 26f, and 26i are fixed to an area where the thickness of the circuit board 24 is thin. Thus, the lower surface of the circuit board 24 and the lower surface portions 26c, 26f, and 26i substantially constitute one plane.
　更に、上面部２６ｂ，２６ｅ，２６ｈは、上側から見たときに、回路基板２４の左側の辺、右側の辺及び前側の辺に沿って延在している。そのため、レセプタクルカバー２６は、上側から見たときに、レセプタクル本体２２とは重なっていない。また、回路基板２４の後ろ側の辺近傍にはレセプタクルカバー２６が存在していないので、レセプタクルカバー２６は、後ろ側から見たときに、レセプタクル本体２２とは重なっていない。 Furthermore, the upper surface portions 26b, 26e, and 26h extend along the left side, the right side, and the front side of the circuit board 24 when viewed from above. Therefore, the receptacle cover 26 does not overlap the receptacle body 22 when viewed from above. In addition, since the receptacle cover 26 does not exist in the vicinity of the rear side of the circuit board 24, the receptacle cover 26 does not overlap the receptacle body 22 when viewed from the rear side.

An optical fiber 100 is connected to the plug 50. The optical fiber 100 extends from the rear end of the plug 50 along the front-rear direction.
　プラグ本体５２は、直方体状の透明な樹脂部材であり、上面、下面、右面、左面、前面及び後面を有している。プラグ本体５２の材料は、例えば、透光性を有するエポキシ系樹脂である。プラグ本体５２は、光ファイバ１００の先端（前端）に設けられている。また、プラグ本体５２は、図２、図５及び図６に示すように、位置決め部５８（図５及び図６に図示）及び全反射面Ｍ（図２に図示）を有している。 The plug main body 52 is a rectangular parallelepiped transparent resin member, and has an upper surface, a lower surface, a right surface, a left surface, a front surface, and a rear surface. The material of the plug body 52 is, for example, an epoxy resin having translucency. The plug body 52 is provided at the tip (front end) of the optical fiber 100. Further, as shown in FIGS. 2, 5, and 6, the plug body 52 has a positioning portion 58 (shown in FIGS. 5 and 6) and a total reflection surface M (shown in FIG. 2).
　下面は、下側を向く面であり、下面の前半分を特に、対向面Ｓ２２と呼ぶ。また、プラグ本体５２の上面には、図２に示すように、全反射面Ｍが設けられている。全反射面Ｍは、前斜め上側を向く法線ベクトルを有する平面であり、プラグ本体５２の上面の一部が窪むことにより形成されている。全反射面Ｍは、上側から見たときに、複数の発光素子３０、複数の受光素子及び複数のレンズ３４と重なっている。更に、全反射面Ｍは、前側から見たときに、光ファイバ１００の先端と重なっている。全反射面Ｍは、複数の発光素子３０から出射され、複数のレンズ３４を通過した光Ｂを光ファイバ１００に向けて反射する。また、全反射面Ｍは、光ファイバ１００から出射された光Ｂを複数のレンズ３４及び複数の受光素子３２に向けて反射する。 The lower surface is a surface facing downward, and the front half of the lower surface is particularly referred to as a facing surface S22. Further, a total reflection surface M is provided on the upper surface of the plug body 52 as shown in FIG. The total reflection surface M is a plane having a normal vector facing the front oblique upper side, and is formed by a part of the upper surface of the plug body 52 being recessed. The total reflection surface M overlaps the plurality of light emitting elements 30, the plurality of light receiving elements, and the plurality of lenses 34 when viewed from above. Further, the total reflection surface M overlaps the tip of the optical fiber 100 when viewed from the front side. The total reflection surface M reflects the light B emitted from the plurality of light emitting elements 30 and passing through the plurality of lenses 34 toward the optical fiber 100. The total reflection surface M reflects the light B emitted from the optical fiber 100 toward the plurality of lenses 34 and the plurality of light receiving elements 32.
　なお、全反射面Ｍは、曲面形状をなすことにより、レンズとしての機能も併せ持っていてもよい。すなわち、発光素子３０からレンズ３４を通過した光Ｂを全反射面Ｍにより集光して光ファイバ１００に入射させてもよい。また、光ファイバ１００からの出射光を、全反射面Ｍによりコリメートしてもよい。 The total reflection surface M may have a function as a lens by forming a curved surface. That is, the light B that has passed through the lens 34 from the light emitting element 30 may be collected by the total reflection surface M and incident on the optical fiber 100. Further, the light emitted from the optical fiber 100 may be collimated by the total reflection surface M.
　位置決め部５８は、対向面Ｓ２２に設けられている位置決め突起５８ａ～５８ｄを含んでいる。位置決め突起５８ａは、対向面Ｓ２２の右側の辺の中央近傍において左右方向に延在する突起である。位置決め突起５８ｂは、対向面Ｓ２２の左側の辺の中央近傍辺において左右方向に延在する突起である。位置決め突起５８ｃは、対向面Ｓ２２の前側の辺の中央近傍において前後方向に延在する突起である。位置決め突起５８ｄは、対向面Ｓ２２の後ろ側の辺の中央近傍において前後方向に延在する突起である。これにより、位置決め突起５８ａ～５８ｄ（すなわち、位置決め部５８）は、下側から見たときに、前後方向及び左右方向に延在する対角線を有する仮想の正方形の角に配置されている。そして、位置決め溝２８ａ～２８ｄは、上側から見たときに、位置決め突起５８ａ～５８ｄに倣った形状をなしている。 The positioning portion 58 includes positioning protrusions 58a to 58d provided on the facing surface S22.

The retaining portion 54g protrudes from the rear side of the right surface portion 54c toward the right rear side.
　以上のようなプラグカバー５４は、プラグ本体５２に対してシリコン系接着剤等により固定される。 The plug cover 54 as described above is fixed to the plug body 52 with a silicon-based adhesive or the like.
　スライダ５６は、一枚の金属板（例えば、ＳＵＳ）が折り曲げ加工されることにより作製されており、前後方向に並ぶ第１の位置と第２の位置との間をプラグ本体５２に対して移動可能に構成されている。第２の位置は、第１の位置に対して前側に位置している。換言すれば、第１の位置は、第２の位置に対して後ろ側に位置している。スライダ５６は、上面部５６ａ、左面部５６ｂ、張り出し部５６ｃ，５６ｇ、ガイド部５６ｄ，５６ｈ、下面部５６ｅ，５６ｉ及び右面部５６ｆを含んでいる。 The slider 56 is manufactured by bending a single metal plate (for example, SUS), and moves with respect to the plug body 52 between a first position and a second position arranged in the front-rear direction. It is configured to be possible. The second position is located on the front side with respect to the first position. In other words, the first position is located on the rear side with respect to the second position. The slider 56 includes an upper surface portion 56a, a left surface portion 56b, overhang portions 56c and 56g, guide portions 56d and 56h, lower surface portions 56e and 56i, and a right surface portion 56f.
　上面部５６ａは、上面部５４ａ上に設けられ、長方形状をなしている。上面部５６ａの左右方向の幅は上面部５４ａの左右方向の幅と実質的に等しく、上面部５６ａの前後方向の長さは上面部５４ａの前後方向の長さより短い。 The upper surface portion 56a is provided on the upper surface portion 54a and has a rectangular shape. The width of the upper surface portion 56a in the left-right direction is substantially equal to the width of the upper surface portion 54a in the left-right direction, and the length of the upper surface portion 56a in the front-rear direction is shorter than the length of the upper surface portion 54a in the front-rear direction.
　左面部５６ｂは、左面部５４ｂの左面の一部を覆っている。具体的には、左面部５６ｂの後ろ半分は、左面部５４ｂ及びプラグ本体５２の下端まで到達している。一方、左面部５６ｂの前半分は、左面部５４ｂの上下方向の中央まで到達しており、プラグ本体５２の下端まで到達していない。下面部５６ｅは、左面部５６ｂの後ろ半分の下端から右側に折り曲げられている。これにより、下面部５６ｅは、プラグ本体５２の下面に回り込んでいる。 The left surface portion 56b covers a part of the left surface of the left surface portion 54b. Specifically, the back half of the left surface portion 56 b reaches the left surface portion 54 b and the lower end of the plug body 52. On the other hand, the front half of the left surface portion 56b reaches the center in the vertical direction of the left surface portion 54b and does not reach the lower end of the plug body 52. The lower surface portion 56e is bent rightward from the lower end of the rear half of the left surface portion 56b. As a result, the lower surface portion 56 e goes around the lower surface of the plug body 52.
　張り出し部５６ｃは、プラグ本体５２から左側に向かって延在しており、具体的には、左面部５６ｂの前半分の下端から左側に向かって延在している。張り出し部５６ｃは、左面部５６ｂの前半分の下端から左側に向かって折れ曲がっている。張り出し部５６ｃは、左面部５６ｂに右端を支持されることにより、左端が上下に動くように弾性変形することができる。ここで、スライダ５６は、上側を向く圧接面Ｓ１３（図１参照）を有している。本実施形態では、圧接面Ｓ１３は、張り出し部５６ｃにおける上側を向く面である。ガイド部５６ｄは、張り出し部５６ｃの前側の端部に設けられており、前側に行くにしたがって下側に向かうように傾斜している。 The overhanging portion 56c extends from the plug main body 52 toward the left side, and specifically extends from the lower end of the front half of the left surface portion 56b toward the left side. The projecting portion 56c is bent toward the left side from the lower end of the front half of the left surface portion 56b. The overhanging portion 56c can be elastically deformed so that the left end moves up and down by being supported at the right end by the left surface portion 56b. Here, the slider 56 has a pressure contact surface S13 (see FIG. 1) facing upward. In the present embodiment, the pressure contact surface S13 is a surface facing the upper side in the overhanging portion 56c. The guide portion 56d is provided at the front end portion of the overhang portion 56c, and is inclined so as to go downward as it goes to the front side.
　右面部５６ｆは、右面部５４ｃの右面の一部を覆っている。具体的には、右面部５６ｆの後ろ半分は、右面部５４ｃ及びプラグ本体５２の下端まで到達している。一方、右面部５６ｆの前半分は、右面部５４ｃの上下方向の中央まで到達しており、プラグ本体５２の下端まで到達していない。下面部５６ｉは、右面部５６ｆの後ろ半分の下端から左側に折れ曲がっている。これにより、下面部５６ｉは、プラグ本体５２の下面に回り込んでいる。このように、スライダ５６は、プラグ本体５２及びプラグカバー５４の周囲を囲むことにより、プラグ本体５２及びプラグカバー５４から脱落しないように構成されている。 The right surface portion 56f covers a part of the right surface of the right surface portion 54c. Specifically, the rear half of the right surface portion 56 f reaches the right surface portion 54 c and the lower end of the plug body 52. On the other hand, the front half of the right surface portion 56f reaches the center in the vertical direction of the right surface portion 54c and does not reach the lower end of the plug body 52. The lower surface portion 56i is bent leftward from the lower end of the rear half of the right surface portion 56f. Thereby, the lower surface portion 56 i wraps around the lower surface of the plug body 52. As described above, the slider 56 is configured not to fall off the plug body 52 and the plug cover 54 by surrounding the periphery of the plug body 52 and the plug cover 54.
　張り出し部５６ｇは、プラグ本体５２から右側に向かって延在しており、具体的には、右面部５６ｆの前半分の下端から右側に向かって延在している。より詳細には、張り出し部５６ｇは、右面部５６ｆの前半分の下端から右側に向かって折れ曲がっている。張り出し部５６ｇは、右面部５６ｆに左端を支持されることにより、右端が上下に動くように弾性変形することができる。ここで、スライダ５６は、上側を向く圧接面Ｓ１４（図１参照）を有している。本実施形態では、圧接面Ｓ１４は、張り出し部５６ｇにおける上側を向く面である。ガイド部５６ｈは、張り出し部５６ｇの前側の端部に設けられており、前側に行くにしたがって下側に向かうように傾斜している。 The protruding portion 56g extends from the plug body 52 toward the right side, and specifically extends from the lower end of the front half of the right surface portion 56f toward the right side. More specifically, the protruding portion 56g is bent toward the right side from the lower end of the front half of the right surface portion 56f. The protruding portion 56g can be elastically deformed so that the right end moves up and down by being supported at the left end by the right surface portion 56f. Here, the slider 56 has a pressure contact surface S14 (see FIG. 1) facing upward. In the present embodiment, the pressure contact surface S14 is a surface facing the upper side in the projecting portion 56g. The guide portion 56h is provided at the front end portion of the projecting portion 56g, and is inclined so as to go downward as it goes to the front side.
（レセプタクルとプラグとの接続）
　以下に、レセプタクル２０とプラグ５０との接続について図面を参照しながら説明する。図７及び図８は、プラグ５０をレセプタクル２０に装着する際の外観斜視図である。 (Connection between receptacle and plug)
Hereinafter, the connection between the receptacle 20 and the plug 50 will be described with reference to the drawings. 7 and 8 are external perspective views when the plug 50 is attached to the receptacle 20.
　まず、組立者は、図７に示すように、レセプタクル２０上にプラグ５０を位置させる。このとき、スライダ５６は、プラグ本体５２に対して第１の位置に位置している。第１の位置とは、本実施形態に係る光伝送モジュール１０においては、位置決め部５８よりも後ろ側の位置である。第１の位置にスライダ５６が位置すると、左面部５６ｂの後端及び右面部５６ｆの後端がそれぞれ抜け止部５４ｆ，５４ｇに接触する。 First, the assembler places the plug 50 on the receptacle 20 as shown in FIG. At this time, the slider 56 is located at the first position with respect to the plug body 52. The first position is a position behind the positioning unit 58 in the optical transmission module 10 according to the present embodiment. When the slider 56 is positioned at the first position, the rear end of the left surface portion 56b and the rear end of the right surface portion 56f are in contact with the retaining portions 54f and 54g, respectively.
　次に、組立者は、図８に示すように、プラグ５０を下降させて、上面Ｓ２１と対向面Ｓ２２とを対向させる。これにより、位置決め部２８が位置決め部５８に嵌り、レセプタクル２０とプラグ５０との前後方向及び左右方向の位置決めが行われる。 Next, as shown in FIG. 8, the assembler lowers the plug 50 so that the upper surface S21 and the opposite surface S22 face each other. Thereby, the positioning part 28 fits into the positioning part 58, and the receptacle 20 and the plug 50 are positioned in the front-rear direction and the left-right direction.
　なお、図８では、スライダ５６は、第１の位置に位置している。このようにスライダ５６が第１の位置に位置する場合には、張り出し部５６ｃ，５６ｇはそれぞれ、上面部２６ｂ，２６ｅには接触していない。そのため、圧接面Ｓ１３，Ｓ１４はそれぞれ、圧接面Ｓ１１，Ｓ１２と接触していない。 In FIG. 8, the slider 56 is located at the first position. Thus, when the slider 56 is located in the first position, the projecting portions 56c and 56g are not in contact with the upper surface portions 26b and 26e, respectively. Therefore, the press contact surfaces S13 and S14 are not in contact with the press contact surfaces S11 and S12, respectively.
　次に、組立者は、図１に示すように、スライダ５６を第１の位置から前側に移動させて第２の位置に移動させる。スライダ５６が第２の位置にある場合には、上面Ｓ２１及び対向面Ｓ２２は、上側から見たときに、張り出し部５６ｃ，５６ｇの間に位置している。更に、スライダ５６が第２の位置にある場合には、左面部５６ｂの前端及び右面部５６ｆの前端がそれぞれ抜け止部５４ｄ，５４ｅに接触する。 Next, as shown in FIG. 1, the assembler moves the slider 56 from the first position to the front side to move to the second position. When the slider 56 is in the second position, the upper surface S21 and the facing surface S22 are positioned between the overhang portions 56c and 56g when viewed from the upper side. Further, when the slider 56 is in the second position, the front end of the left surface portion 56b and the front end of the right surface portion 56f are in contact with the retaining portions 54d and 54e, respectively.
　ここで、スライダ５６の移動についてより詳細に説明する。図８に示すように、張り出し部５６ｃ，５６ｇの圧接面Ｓ１３，Ｓ１４はそれぞれ、上面部２６ｂ，２６ｅの圧接面Ｓ１１，Ｓ１２よりも僅かに上側に位置している。したがって、スライダ５６を第１の位置から第２の位置に移動させると、張り出し部５６ｃ，５６ｇが上面部２６ｂ，２６ｅに引っかかる。そこで、組立者は、張り出し部５６ｃ，５６ｇを僅かに押し下げた状態で、スライダ５６を移動させる。これにより、張り出し部５６ｃ，５６ｇが上面部２６ｂ，２６ｅの下側に位置するようになる。そして、組立者が張り出し部５６ｃ，５６ｇの押し下げを解除すると、張り出し部５６ｃ，５６ｇが上側に復帰し、圧接面Ｓ１１，Ｓ１２と圧接面Ｓ１３，Ｓ１４とが圧接する。その結果、図４Ｃに示すように、レセプタクルカバー２６とスライダ５６とが上下方向に押し合うことにより、レセプタクル本体２２とプラグ本体５２とが上下方向に押し合う。 Here, the movement of the slider 56 will be described in more detail. As shown in FIG. 8, the press contact surfaces S13 and S14 of the overhang portions 56c and 56g are positioned slightly above the press contact surfaces S11 and S12 of the upper surface portions 26b and 26e, respectively. Therefore, when the slider 56 is moved from the first position to the second position, the projecting portions 56c and 56g are caught by the upper surface portions 26b and 26e. Therefore, the assembler moves the slider 56 in a state where the projecting portions 56c and 56g are slightly pushed down. As a result, the projecting portions 56c and 56g are positioned below the upper surface portions 26b and 26e. When the assembler releases the push-down of the overhang portions 56c, 56g, the overhang portions 56c, 56g return to the upper side, and the press contact surfaces S11, S12 and the press contact surfaces S13, S14 come into pressure contact. As a result, as shown in FIG. 4C, when the receptacle cover 26 and the slider 56 are pressed in the vertical direction, the receptacle main body 22 and the plug main body 52 are pressed in the vertical direction.
（効果）
　本実施形態に係るレセプタクル２０によれば、回路基板２４とレセプタクルカバー２６との間の位置ずれを抑制できる。より詳細には、回路基板２４には、スリットＳＬ１，ＳＬ２が設けられている。レセプタクルカバー２６は、位置決め部２６ｊ，２６ｋを含んでいる。位置決め部２６ｊ，２６ｋはそれぞれ、スリットＳＬ１，ＳＬ２内に位置している。これにより、回路基板２４とレセプタクルカバー２６とが位置決めされる。 (effect)
According to the receptacle 20 according to the present embodiment, the positional deviation between the circuit board 24 and the receptacle cover 26 can be suppressed. More specifically, the circuit board 24 is provided with slits SL1 and SL2. The receptacle cover 26 includes positioning portions 26j and 26k. The positioning portions 26j and 26k are located in the slits SL1 and SL2, respectively. Thereby, the circuit board 24 and the receptacle cover 26 are positioned.
　また、レセプタクル２０によれば、回路基板２４とレセプタクルカバー２６とをより確実に固定することができる。より詳細には、回路基板２４は、例えば、セラミックス等により作製される。レセプタクルカバー２６は、例えば、ＳＵＳ等の金属により作製される。このように、回路基板２４とレセプタクルカバー２６とは、異なる材料により作製される。一般的に、異なる材料により作製された２種類の部材を接着部材により固定する場合には、一方の部材に対する接着部材の接着性が相対的に高く、他方の部材に対する接着部材の接着性が相対的に低くなる。すなわち、接着部材において、両方の部材に対して高い接着性を得ることが難しい。そのため、接着部材といずれか一方の部材との間で剥離が発生し易い。 Moreover, according to the receptacle 20, the circuit board 24 and the receptacle cover 26 can be more reliably fixed. More specifically, the circuit board 24 is made of, for example, ceramics. The receptacle cover 26 is made of a metal such as SUS, for example. Thus, the circuit board 24 and the receptacle cover 26 are made of different materials. Generally, when two types of members made of different materials are fixed by an adhesive member, the adhesive property of the adhesive member to one member is relatively high, and the adhesive property of the adhesive member to the other member is relatively Lower. That is, in the adhesive member, it is difficult to obtain high adhesion to both members. Therefore, peeling easily occurs between the adhesive member and one of the members.
　そこで、レセプタクル２０では、接着部材３３ａは、左面部２６ａと突出部２７ａとに固着している。左面部２６ａ及び突出部２７ａは、レセプタクルカバー２６の一部であり、金属により作製されている。そのため、金属に対して高い接着性を有する接着部材３３ａを用いれば、接着部材３３ａが左面部２６ａ及び突出部２７ａの両方に強固に固着する。したがって、接着部材３３ａと左面部２６ａ又は突出部２７ａとの間で剥離が発生しにくい。更に、左面部２６ａは、スリットＳＬ１が延在する延在方向（前後方向）に直交する幅方向（左側）に位置している。これにより、接着部材３３ａは、左面部２６ａと突出部２７ａとの間において回路基板２４の上側に存在するようになる。よって、位置決め部２６ｊがスリットＳＬ１から抜けようとすると、接着部材３３ａが回路基板２４に引っ掛かるようになる。その結果、接着部材３３ａは、位置決め部２６ｊがスリットＳＬ１から抜けることを効果的に抑制する。同じ理由により、接着部材３３ｂは、位置決め部２６ｋがスリットＳＬ２から抜けることを効果的に抑制する。以上より、レセプタクル２０によれば、回路基板２４とレセプタクルカバー２６とをより確実に固定することができる。 Therefore, in the receptacle 20, the adhesive member 33a is fixed to the left surface portion 26a and the protruding portion 27a. The left surface part 26a and the protruding part 27a are part of the receptacle cover 26 and are made of metal. Therefore, if the adhesive member 33a having high adhesiveness to the metal is used, the adhesive member 33a is firmly fixed to both the left surface portion 26a and the protruding portion 27a. Therefore, peeling hardly occurs between the adhesive member 33a and the left surface portion 26a or the protruding portion 27a. Furthermore, the left surface portion 26a is located in the width direction (left side) orthogonal to the extending direction (front-rear direction) in which the slit SL1 extends. Accordingly, the adhesive member 33a is present on the upper side of the circuit board 24 between the left surface portion 26a and the protruding portion 27a. Therefore, when the positioning portion 26j tries to come out from the slit SL1, the adhesive member 33a is caught on the circuit board 24. As a result, the adhesive member 33a effectively suppresses the positioning portion 26j from coming out of the slit SL1. For the same reason, the adhesive member 33b effectively suppresses the positioning portion 26k from coming out of the slit SL2. As described above, according to the receptacle 20, the circuit board 24 and the receptacle cover 26 can be more reliably fixed.
　また、レセプタクル２０では、接着部材３３ａが左面部２６ａ及び突出部２７ａに固着することにより、回路基板２４とレセプタクルカバー２６とが固定されている。そのため、金属に対する高い接着性が接着部材３３ａに対して要求され、セラミックスに対する高い接着性が接着部材３３ａに要求されない。これにより、接着部材３３ａの材料の選択肢が広がる。同じ理由により、レセプタクル２０では、接着部材３３ｂの材料の選択肢が広がる。 In the receptacle 20, the circuit board 24 and the receptacle cover 26 are fixed by the adhesive member 33a being fixed to the left surface portion 26a and the protruding portion 27a. Therefore, high adhesiveness to metal is required for the adhesive member 33a, and high adhesiveness to ceramics is not required for the adhesive member 33a. Thereby, the choice of the material of the adhesion member 33a spreads. For the same reason, the receptacle 20 has a wider range of materials for the adhesive member 33b.
　また、光伝送モジュール１０によれば、レセプタクル２０とプラグ５０とを容易に接続することができる。より詳細には、光伝送モジュール１０では、レセプタクル２０が位置決め部２８を備え、プラグ５０が位置決め部５８を備えている。そして、位置決め部２８が位置決め部５８に嵌ることにより、レセプタクル２０とプラグ５０との前後方向及び左右方向における位置決めが行われる。すなわち、発光素子３０及び受光素子３２と光ファイバ１００とが光学的に結合する。この状態で、スライダ５６が第１の位置から第２の位置に移動させられると、圧接面Ｓ１１，Ｓ１２と圧接面Ｓ１３，Ｓ１４とが圧接し、プラグ本体５２がレセプタクル本体２２に押し付けられる。その結果、レセプタクル２０とプラグ５０とが固定される。以上のように、光伝送モジュール１０では、コネクタセット５００のように板ばね５０６及びねじ５０８，５１０を用いることなく、スライダ５６を移動させるだけで、レセプタクル２０とプラグ５０とを固定できる。よって、光伝送モジュール１０によれば、レセプタクル２０とプラグ５０とを容易に接続することができる。 Further, according to the optical transmission module 10, the receptacle 20 and the plug 50 can be easily connected. More specifically, in the optical transmission module 10, the receptacle 20 includes the positioning unit 28, and the plug 50 includes the positioning unit 58. Then, when the positioning portion 28 is fitted into the positioning portion 58, the receptacle 20 and the plug 50 are positioned in the front-rear direction and the left-right direction. That is, the light emitting element 30 and the light receiving element 32 and the optical fiber 100 are optically coupled. In this state, when the slider 56 is moved from the first position to the second position, the pressure contact surfaces S11, S12 and the pressure contact surfaces S13, S14 are in pressure contact, and the plug main body 52 is pressed against the receptacle main body 22. As a result, the receptacle 20 and the plug 50 are fixed. As described above, in the optical transmission module 10, the receptacle 20 and the plug 50 can be fixed only by moving the slider 56 without using the leaf spring 506 and the screws 508 and 510 unlike the connector set 500. Therefore, according to the optical transmission module 10, the receptacle 20 and the plug 50 can be easily connected.
　また、光伝送モジュール１０によれば、スライダ５６と光ファイバ１００とが接触することが防止される。より詳細には、スライダ５６は、プラグ本体５２に対して前後方向に移動する。また、光ファイバ１００は、プラグ本体５２から後ろ側に向かって延在している。そのため、スライダ５６の移動方向と光ファイバ１００の延在方向とが一致している。これにより、スライダ５６が光ファイバ１００を横切ることがないので、スライダ５６と光ファイバ１００とが接触することが防止される。 Further, according to the optical transmission module 10, the slider 56 and the optical fiber 100 are prevented from contacting each other. More specifically, the slider 56 moves in the front-rear direction with respect to the plug body 52. The optical fiber 100 extends from the plug body 52 toward the rear side. Therefore, the moving direction of the slider 56 matches the extending direction of the optical fiber 100. Thereby, since the slider 56 does not cross the optical fiber 100, it is prevented that the slider 56 and the optical fiber 100 contact.
　また、光伝送モジュール１０によれば、レセプタクル２０とプラグ５０とをより強固に固定することができる。より詳細には、プラグ本体５２が右側又は左側のいずれか一方のみにおいて下側に押さえつけられると、プラグ５０が前後方向に延在する軸を中心として回転するおそれがある。そこで、光伝送モジュール１０では、レセプタクル本体２２とプラグ本体５２の左側において圧接面Ｓ１１と圧接面Ｓ１３とが圧接し、レセプタクル本体２２とプラグ本体５２の右側において圧接面Ｓ１２と圧接面Ｓ１４とが圧接する。これにより、プラグ本体５２は、左右両側において下側に向けて押さえつけられるようになる。その結果、プラグ５０が回転することが抑制され、レセプタクル２０とプラグ５０とをより強固に固定することができる。 Further, according to the optical transmission module 10, the receptacle 20 and the plug 50 can be more firmly fixed. More specifically, if the plug body 52 is pressed down only on either the right side or the left side, the plug 50 may rotate around an axis extending in the front-rear direction. Therefore, in the optical transmission module 10, the pressure contact surface S11 and the pressure contact surface S13 are in pressure contact with each other on the left side of the receptacle body 22 and the plug body 52, and the pressure contact surface S12 and the pressure contact surface S14 are pressure contacted on the right side of the receptacle body 22 and the plug body 52. To do. Thereby, the plug main body 52 comes to be pressed down on the left and right sides. As a result, the rotation of the plug 50 is suppressed, and the receptacle 20 and the plug 50 can be more firmly fixed.
　特に、光伝送モジュール１０では、スライダ５６が第２の位置にある場合に、上面Ｓ２１及び対向面Ｓ２２は、上側から見たときに、張り出し部５６ｃと張り出し部５６ｇとの間に位置している。これにより、張り出し部５６ｃ，５６ｇが上面部２６ｂ，２６ｅに押さえつけられる力が効率よくプラグ本体５２に伝達される。そのため、プラグ本体５２がレセプタクル本体２２に押し付けられ、レセプタクル２０とプラグ５０とがより強固に固定されるようになる。 In particular, in the optical transmission module 10, when the slider 56 is in the second position, the upper surface S21 and the facing surface S22 are located between the projecting portion 56c and the projecting portion 56g when viewed from above. . As a result, the force with which the projecting portions 56c and 56g are pressed against the upper surface portions 26b and 26e is efficiently transmitted to the plug body 52. Therefore, the plug main body 52 is pressed against the receptacle main body 22, and the receptacle 20 and the plug 50 are more firmly fixed.
　なお、前記実施形態に係る光伝送モジュール１０では、圧接面Ｓ１１，Ｓ１３との組及び圧接面Ｓ１２，Ｓ１４との組の２組によりレセプタクル２０とプラグ５０とを固定しているが、１組の圧接面によりレセプタクル２０とプラグ５０とを固定してもよい。 In the optical transmission module 10 according to the above-described embodiment, the receptacle 20 and the plug 50 are fixed by two sets of the set with the press contact surfaces S11 and S13 and the set with the press contact surfaces S12 and S14. The receptacle 20 and the plug 50 may be fixed by the pressure contact surface.
　また、光伝送モジュール１０によれば、前側に行くにしたがって下側に向かうガイド部５６ｄ，５６ｈが設けられている。そのため、スライダ５６が前側に移動させられると、張り出し部５６ｃ，５６ｇがそれぞれガイド部５６ｄ，５６ｈにより上面部２６ｂ，２６ｅの下側に導かれるようになる。よって、スライダ５６をスムーズに移動させることが可能となる。 Further, according to the optical transmission module 10, the guide portions 56d and 56h that are directed downward toward the front side are provided. Therefore, when the slider 56 is moved to the front side, the projecting portions 56c and 56g are guided to the lower side of the upper surface portions 26b and 26e by the guide portions 56d and 56h, respectively. Therefore, the slider 56 can be moved smoothly.
　また、光伝送モジュール１０によれば、回路基板２４が破損することを抑制できる。より詳細には、レセプタクル２０は、図４Ｃに示すように、回路基板８０に実装される。主面Ｓ２は、回路基板８０と対向する実装面である。このとき、レセプタクルカバー２６の下面部２６ｃ，２６ｆの下側の面は、回路基板８０に対して半田により固定される。そのため、レセプタクル２０の張り出し部５６ｃ，５６ｇにより、レセプタクルカバー２６が上側に引っぱられたとしても、下面部２６ｃ，２６ｆの下側の面が半田により強固に回路基板８０に固定されているため、下面部２６ｃ，２６ｆから回路基板２４に大きな力が加わることが抑制される。その結果、回路基板２４が破損することが抑制される。なお、回路基板２４は、比較的に破損しやすいガラス基板２４ａを含んでいるので、光伝送モジュール１０の構成は特に有効である。 Further, according to the optical transmission module 10, it is possible to prevent the circuit board 24 from being damaged. More specifically, the receptacle 20 is mounted on the circuit board 80 as shown in FIG. 4C. The main surface S2 is a mounting surface facing the circuit board 80. At this time, the lower surfaces of the lower surface portions 26 c and 26 f of the receptacle cover 26 are fixed to the circuit board 80 by soldering. For this reason, even if the receptacle cover 26 is pulled upward by the overhanging portions 56c and 56g of the receptacle 20, the lower surface of the lower surface portions 26c and 26f is firmly fixed to the circuit board 80 by the solder. It is possible to prevent a large force from being applied to the circuit board 24 from the portions 26c and 26f. As a result, the circuit board 24 is prevented from being damaged. In addition, since the circuit board 24 includes the glass substrate 24a which is relatively easily damaged, the configuration of the optical transmission module 10 is particularly effective.
　また、光伝送モジュール１０によれば、レセプタクル２０とプラグ５０とが正確に位置決めされるようになる。より詳細には、プラグ５０の位置決め部５８は正方形の角に配置された凸部であり、レセプタクル２０の位置決め部２８は位置決め部５８に倣った形状をなす凹部である。したがって、前後方向の位置決めは、主に、位置決め溝２８ａ，２８ｂが位置決め突起５８ａ，５８ｂに嵌ることにより行われる。また、左右方向の位置決めは、主に、位置決め溝２８ｃ，２８ｄが位置決め突起５８ｃ，５８ｄに嵌ることにより行われる。このように、前後方向と左右方向との位置決めが均等に行われるので、レセプタクル２０とプラグ５０とが正確に位置決めされるようになる。 Further, according to the optical transmission module 10, the receptacle 20 and the plug 50 are accurately positioned. More specifically, the positioning portion 58 of the plug 50 is a convex portion arranged at a square corner, and the positioning portion 28 of the receptacle 20 is a concave portion having a shape following the positioning portion 58. Therefore, the positioning in the front-rear direction is performed mainly by fitting the positioning grooves 28a and 28b to the positioning protrusions 58a and 58b. Further, the positioning in the left-right direction is performed mainly by fitting the positioning grooves 28c, 28d to the positioning protrusions 58c, 58d. As described above, since the positioning in the front-rear direction and the left-right direction is performed equally, the receptacle 20 and the plug 50 are accurately positioned.
　また、光伝送モジュール１０によれば、光路にずれが生じることが抑制される。より詳細には、温度が上昇するとレセプタクル本体２２及びプラグ本体５２が膨張する。レセプタクル本体２２の材料とプラグ本体５２の材料とは異なるので、これらの線膨張係数も異なる。したがって、温度が上昇すると、レセプタクル本体２２の膨張量とプラグ本体５２の膨張量とに差が生じる。このような膨張量の差は、光路にずれが生じる原因となる。 Further, according to the optical transmission module 10, it is possible to suppress the occurrence of a shift in the optical path. More specifically, when the temperature rises, the receptacle body 22 and the plug body 52 expand. Since the material of the receptacle body 22 and the material of the plug body 52 are different, their linear expansion coefficients are also different. Therefore, when the temperature rises, a difference occurs between the expansion amount of the receptacle body 22 and the expansion amount of the plug body 52. Such a difference in expansion amount causes a shift in the optical path.
　そこで、光伝送モジュール１０では、プラグ５０の位置決め部５８は、前後方向及び左右方向に延在する対角線を有する仮想の正方形の角に配置された凸部であり、レセプタクル２０の位置決め部２８は位置決め部５８に倣った形状をなす凹部である。これにより、位置決め部２８，５８は正方形の中心（対角線の交点）から放射状に膨張するようになる。よって、位置決め部２８，５８の正方形の中心近傍では、レセプタクル２０とプラグ５０とのずれが生じにくい。したがって、位置決め部２８，５８の正方形の中心近傍に光路（すなわち、発光素子３０、受光素子３２及びレンズ３４）が位置すれば、光路にずれが生じることが抑制される。 Therefore, in the optical transmission module 10, the positioning portion 58 of the plug 50 is a convex portion arranged at a corner of a virtual square having diagonal lines extending in the front-rear direction and the left-right direction, and the positioning portion 28 of the receptacle 20 is positioned. It is a concave portion having a shape that follows the portion 58. Thereby, the positioning parts 28 and 58 come to expand radially from the center of the square (intersection of diagonal lines). Therefore, the receptacle 20 and the plug 50 are unlikely to be displaced near the center of the square of the positioning portions 28 and 58. Therefore, if the optical path (that is, the light emitting element 30, the light receiving element 32, and the lens 34) is positioned in the vicinity of the center of the square of the positioning portions 28 and 58, the occurrence of a shift in the optical path is suppressed.
（第１の変形例）
　以下に、第１の変形例に係るレセプタクル２０ａについて図面を参照しながら説明する。図９は、第１の変形例に係るレセプタクル２０ａを備える光伝送モジュール１０ａの断面構造図である。図９は、図１のＢ－Ｂにおける断面構造図である。 (First modification)
The receptacle 20a according to the first modification will be described below with reference to the drawings. FIG. 9 is a cross-sectional structure diagram of an optical transmission module 10a including a receptacle 20a according to a first modification. FIG. 9 is a cross-sectional structural view taken along line BB in FIG.
　レセプタクル２０ａは、接着部材３３ａ，３３ｂが固着している対象物においてレセプタクル２０と相違する。レセプタクル２０では、接着部材３３ａは、左面部２６ａ及び突出部２７ａに固着し、接着部材３３ｂは、右面部２６ｄ及び突出部２７ｂに固着している。これにより、接着部材３３ａが左面部２６ａと突出部２７ａとの間に位置する回路基板２４に引っ掛かるようになり、突出部２７ａがスリットＳＬ１から抜けることが防止されている。同様に、接着部材３３ｂが右面部２６ｄと突出部２７ｂとの間に位置する回路基板２４に引っ掛かるようになり、突出部２７ｂがスリットＳＬ２から抜けることが防止されている。 The receptacle 20a is different from the receptacle 20 in the object to which the adhesive members 33a and 33b are fixed. In the receptacle 20, the adhesive member 33a is fixed to the left surface portion 26a and the protruding portion 27a, and the adhesive member 33b is fixed to the right surface portion 26d and the protruding portion 27b. As a result, the adhesive member 33a is caught by the circuit board 24 located between the left surface portion 26a and the protruding portion 27a, and the protruding portion 27a is prevented from coming off from the slit SL1. Similarly, the adhesive member 33b is caught on the circuit board 24 located between the right surface portion 26d and the protruding portion 27b, and the protruding portion 27b is prevented from coming off from the slit SL2.
　一方、レセプタクル２０ａでは、接着部材３３ａは、突出部２７ａに固着しており、左面部２６ａに固着していない。ここで、上側から見たときに、スリットＳＬ１が延びる方向を延在方向（前後方向）と定義し、延在方向に直交する方向を幅方向（左右方向）と定義する。このとき、接着部材３３ａは、上側から見たときに、スリットＳＬ１の幅方向の両側において回路基板２４に固着（接触）している。 On the other hand, in the receptacle 20a, the adhesive member 33a is fixed to the protruding portion 27a and is not fixed to the left surface portion 26a. Here, when viewed from above, the direction in which the slit SL1 extends is defined as the extending direction (front-rear direction), and the direction orthogonal to the extending direction is defined as the width direction (left-right direction). At this time, the adhesive member 33a is fixed (contacted) to the circuit board 24 on both sides in the width direction of the slit SL1 when viewed from above.
　また、レセプタクル２０ａでは、接着部材３３ｂは、突出部２７ｂに固着しており、右面部２６ｄに固着していない。ここで、上側から見たときに、スリットＳＬ２が延びる方向を延在方向（前後）と定義し、延在方向に直交する方向を幅方向（左右方向）と定義する。このとき、接着部材３３ｂは、上側から見たときに、スリットＳＬ２の幅方向の両側において回路基板２４に固着（接触）している。 In the receptacle 20a, the adhesive member 33b is fixed to the protruding portion 27b and is not fixed to the right surface portion 26d. Here, when viewed from the upper side, a direction in which the slit SL2 extends is defined as an extending direction (front and rear), and a direction orthogonal to the extending direction is defined as a width direction (left and right direction). At this time, the adhesive member 33b is fixed (contacted) to the circuit board 24 on both sides in the width direction of the slit SL2 when viewed from above.
　以上のようなレセプタクル２０ａでは、接着部材３３ａは、上側から見たときに、スリットＳＬ１の左右両側にはみ出している。これにより、接着部材３３ａが回路基板２４に引っ掛かるようになり、突出部２７ａがスリットＳＬ１から抜けることが防止される。同じ理由により、突出部２７ｂがスリットＳＬ２から抜けることが防止される。 In the receptacle 20a as described above, the adhesive member 33a protrudes from the left and right sides of the slit SL1 when viewed from above. As a result, the adhesive member 33a is caught on the circuit board 24, and the protruding portion 27a is prevented from coming out of the slit SL1. For the same reason, the protruding portion 27b is prevented from coming out of the slit SL2.
　なお、接着部材３３ａは、上側から見たときに、スリットＳＬ１の幅方向の少なくとも一方側において回路基板２４に固着していればよい。同様に、接着部材３３ｂは、上側から見たときに、スリットＳＬ２の幅方向の少なくとも一方側において回路基板２４に固着していればよい。 The adhesive member 33a only needs to be fixed to the circuit board 24 on at least one side in the width direction of the slit SL1 when viewed from above. Similarly, the adhesive member 33b only needs to be fixed to the circuit board 24 on at least one side in the width direction of the slit SL2 when viewed from above.
（第２の変形例）
　以下に、第２の変形例に係るプラグ５０ａについて図面を参照しながら説明する。図１０は、プラグ５０ａの外観斜視図である。 (Second modification)
Below, the plug 50a which concerns on a 2nd modification is demonstrated, referring drawings. FIG. 10 is an external perspective view of the plug 50a.
　プラグ５０ａは、ガイド部５６ｄ，５６ｈを備えていない点において、プラグ５０と相違する。プラグ５０ａのその他の点は、プラグ５０と同じであるので説明を省略する。 The plug 50a is different from the plug 50 in that it does not include the guide portions 56d and 56h. Since the other points of the plug 50a are the same as the plug 50, description thereof is omitted.
（第３の変形例）
　以下に、第３の変形例に係る光伝送モジュール１０ｂについて図面を参照しながら説明する。図１１Ａは、光伝送モジュール１０ｂの断面構造図である。 (Third Modification)
Hereinafter, an optical transmission module 10b according to a third modification will be described with reference to the drawings. FIG. 11A is a sectional view of the optical transmission module 10b.
　光伝送モジュール１０ｂは、レセプタクルカバー２６及びスライダ５６の構成において光伝送モジュール１０と相違する。以下に、かかる相違点を中心に光伝送モジュール１０ｂについて説明する。 The optical transmission module 10 b is different from the optical transmission module 10 in the configuration of the receptacle cover 26 and the slider 56. Hereinafter, the optical transmission module 10b will be described focusing on the difference.
　光伝送モジュール１０では、スライダ５６の張り出し部５６ｃ，５６ｇは、内側から上面部２６ｂ，２６ｅの下側に進入している。一方、光伝送モジュール１０ｂでは、スライダ５６の張り出し部５６ｃ，５６ｇは、外側から上面部２６ｂ，２６ｅの下側に進入している。このような構成を有する光伝送モジュール１０ｂも、光伝送モジュール１０と同じ作用効果を奏することができる。 In the optical transmission module 10, the projecting portions 56c and 56g of the slider 56 enter the lower side of the upper surface portions 26b and 26e from the inside. On the other hand, in the optical transmission module 10b, the projecting portions 56c and 56g of the slider 56 enter the lower side of the upper surface portions 26b and 26e from the outside. The light transmission module 10b having such a configuration can also exhibit the same effects as the light transmission module 10.
（第４の変形例）
　以下に、第４の変形例に係るレセプタクル２０ｂについて図面を参照しながら説明する。図１１Ｂは、レセプタクル２０ｂの断面構造図である。 (Fourth modification)
Hereinafter, a receptacle 20b according to a fourth modification will be described with reference to the drawings. FIG. 11B is a cross-sectional structure diagram of the receptacle 20b.
　レセプタクル２０ｂは、スリットＳＬ１，ＳＬ２の位置においてレセプタクル２０と相違する。以下に、かかる相違点を中心にレセプタクル２０ｂについて説明する。 The receptacle 20b is different from the receptacle 20 in the positions of the slits SL1 and SL2. Hereinafter, the receptacle 20b will be described focusing on the difference.
　レセプタクル２０ｂにおいて、スリットＳＬ１，ＳＬ２は、回路基板２４の外縁に接している。より詳細には、スリットＳＬ１は、回路基板２４における前側の辺の左端近傍から前側に向かって延びている。スリットＳＬ２は、回路基板２４における前側の辺の右端近傍から前側に向かって延びている。これにより、回路基板２４を後側から前側へとスライドさせてレセプタクルカバー２６に取り付けることにより、位置決め部２６ｋ，２６ｊをスリットＳＬ１，ＳＬ２内に位置させることができる。すなわち、レセプタクルカバー２６への回路基板２４の取り付けが容易となる。 In the receptacle 20b, the slits SL1 and SL2 are in contact with the outer edge of the circuit board 24. More specifically, the slit SL1 extends from the vicinity of the left end of the front side of the circuit board 24 toward the front side. The slit SL2 extends from the vicinity of the right end of the front side of the circuit board 24 toward the front side. Thereby, the positioning parts 26k and 26j can be positioned in the slits SL1 and SL2 by sliding the circuit board 24 from the rear side to the front side and attaching the circuit board 24 to the receptacle cover 26. That is, the circuit board 24 can be easily attached to the receptacle cover 26.

Moreover, the positioning part 28 may consist of a protrusion and a groove | channel, and the positioning part 58 may consist of a protrusion and a groove | channel.
　また、レセプタクル２０とプラグ５０との構成が入れ替わっていてもよい。すなわち、光伝送モジュール１０，１０ａでは、プラグ５０がスライダ５６を有しているが、レセプタクル２０がスライダを有していてもよい。 Further, the configuration of the receptacle 20 and the plug 50 may be interchanged. That is, in the optical transmission modules 10 and 10a, the plug 50 includes the slider 56, but the receptacle 20 may include the slider.
　なお、圧接面Ｓ１１～Ｓ１４は、面であるとしたが、突起のような点であってもよい。 The pressure contact surfaces S11 to S14 are surfaces, but may be points such as protrusions.

Further, the receptacle 20 and the plug 50 may be fixed by moving the slider 56 in different directions.
