　図１、図２、図７から図１０を参照して、カバー４１は、第１折り返し部８１と、第２折り返し部８６とをさらに有する。第１折り返し部８１および第２折り返し部８６は、シェル部４２と一体に設けられている。第１折り返し部８１および第２折り返し部８６は、シェル部４２を構成する金属板を折り曲げ加工することによって構成されている。 Referring to FIGS. 1, 2, and 7 to 10, the cover 41 further includes a first folded portion 81 and a second folded portion 86. The first folded portion 81 and the second folded portion 86 are provided integrally with the shell portion 42. The first folded portion 81 and the second folded portion 86 are configured by bending a metal plate that constitutes the shell portion 42.
　第１折り返し部８１は、多層基板２１の第１表面２１ａに面して設けられている。第１折り返し部８１は、シェル部４２から、多層基板２１の第１表面２１ａに近づくように折り返される折り返し形状を有する。より具体的には、第１折り返し部８１は、シェル部４２の他方端４２ｋ側の端部から略Ｕ字状に折り返され、シェル部４２の一方端４２ｊ側に向けて延びる折り返し形状を有する。 The first folded portion 81 is provided facing the first surface 21 a of the multilayer substrate 21. The first folded portion 81 has a folded shape that is folded from the shell portion 42 so as to approach the first surface 21 a of the multilayer substrate 21. More specifically, the first folded portion 81 has a folded shape that is folded back in a substantially U shape from the end portion on the other end 42 k side of the shell portion 42 and extends toward the one end 42 j side of the shell portion 42.
　第２折り返し部８６は、多層基板２１を挟んで第１折り返し部８１と対向して設けられている。第２折り返し部８６は、多層基板２１の第２表面２１ｂに面して設けられている。第２折り返し部８６は、シェル部４２から、多層基板２１の第２表面２１ｂに近づくように折り返される折り返し形状を有する。より具体的には、第２折り返し部８６は、シェル部４２の他方端４２ｋ側の端部から略Ｕ字状に折り返され、シェル部４２の一方端４２ｊ側に向けて延びる折り返し形状を有する。第２折り返し部８６は、多層基板２１を挟んで第１折り返し部８１と対称形状を有する。 The second folded portion 86 is provided to face the first folded portion 81 with the multilayer substrate 21 interposed therebetween. The second folded portion 86 is provided facing the second surface 21 b of the multilayer substrate 21. The second folded portion 86 has a folded shape that is folded from the shell portion 42 so as to approach the second surface 21 b of the multilayer substrate 21. More specifically, the second folded portion 86 has a folded shape that is folded back in a substantially U shape from the other end 42 k side end of the shell portion 42 and extends toward the one end 42 j side of the shell portion 42. The second folded portion 86 has a symmetrical shape with the first folded portion 81 across the multilayer substrate 21.
　第１折り返し部８１および第２折り返し部８６は、弾性変形可能に構成されている。すなわち、第１折り返し部８１および第２折り返し部８６は、ばね性を有する。第１折り返し部８１および第２折り返し部８６は、互いに離れる方向（図７中の矢印１２２に示す方向）に弾性変形可能なように構成されている。 The first folded portion 81 and the second folded portion 86 are configured to be elastically deformable. That is, the first folded portion 81 and the second folded portion 86 have spring properties. The first folded portion 81 and the second folded portion 86 are configured to be elastically deformable in directions away from each other (the direction indicated by the arrow 122 in FIG. 7).
　舌部２２は、第１折り返し部８１および第２折り返し部８６を互いに離れる方向に弾性変形させつつ、第１折り返し部８１および第２折り返し部８６の間に配置されている。これにより、第１折り返し部８１から舌部２２に対して、第１表面２１ａを付勢する付勢力が作用し、第２折り返し部８６から舌部２２に対して、第２表面２１ｂを付勢する付勢力が作用する。舌部２２は、第１折り返し部８１および第２折り返し部８６によって挟持されている。 The tongue portion 22 is disposed between the first folded portion 81 and the second folded portion 86 while elastically deforming the first folded portion 81 and the second folded portion 86 away from each other. As a result, a biasing force that biases the first surface 21 a acts on the tongue 22 from the first folded portion 81, and the second surface 21 b is biased on the tongue 22 from the second folded portion 86. The urging force to act acts. The tongue portion 22 is sandwiched between the first folded portion 81 and the second folded portion 86.
　このような構成により、レセプタクル１０の組み立て工程時、シェル部４２の内側に舌部２２が配置された状態を保持して、ケース１２に対するカバー４１および多層基板２１の組み付け作業を容易に行なうことができる。この際、第１折り返し部８１および第２折り返し部８６はシェル部４２に一体に設けられているため、シェル部４２に対する多層基板２１の保持を簡易な構成により実現することができる。 With such a configuration, during the assembly process of the receptacle 10, the assembly of the cover 41 and the multilayer substrate 21 to the case 12 can be easily performed while maintaining the state in which the tongue portion 22 is disposed inside the shell portion 42. it can. At this time, since the first folded portion 81 and the second folded portion 86 are provided integrally with the shell portion 42, the multilayer substrate 21 can be held on the shell portion 42 with a simple configuration.

The second folded portion 86 is electrically connected to the ground electrode 23 on the second surface 21b. The second folded portion 86 is in contact with the ground electrode 23 on the second surface 21b. The electrode group 24 on the first surface 21 a and the electrode group 24 on the second surface 21 b are surrounded by the shell portion 42.
　このような構成により、シェル部４２が、接地電位とされている。これにより、電極群２４を取り囲む電磁シールドを簡易な構成で実現することができる。 With this configuration, the shell portion 42 is set to the ground potential. Thereby, the electromagnetic shield surrounding the electrode group 24 can be realized with a simple configuration.
　図１０中に示すように、第１表面２１ａ上の接地電極２３と、第２表面２１ｂ上の接地電極２３との間の厚みがＬ１であり、舌部２２が挿入されていないシェル部４２単体の状態において、第１折り返し部８１および第２折り返し部８６間の最短長さがＬ２である場合に、Ｌ１＞Ｌ２の関係を満たす。 As shown in FIG. 10, the shell portion 42 alone in which the thickness between the ground electrode 23 on the first surface 21 a and the ground electrode 23 on the second surface 21 b is L1 and the tongue portion 22 is not inserted. In this state, when the shortest length between the first folded portion 81 and the second folded portion 86 is L2, the relationship of L1> L2 is satisfied.
　このような構成により、第１折り返し部８１および第２折り返し部８６による多層基板２１の保持状態をより確実に得ることができる。 With such a configuration, the holding state of the multilayer substrate 21 by the first folded portion 81 and the second folded portion 86 can be obtained more reliably.
　シェル部４２単体の状態において、第１折り返し部８１は、シェル部４２から略Ｕ字状に反転したあと、第１折り返し部８１および第２折り返し部８６の対向方向（図７中の矢印１２２に示す方向）において第２折り返し部８６に近づきながら、シェル部４２の一方端４２ｊ側に向けて延びている。シェル部４２単体の状態において、第２折り返し部８６は、シェル部４２から略Ｕ字状に反転したあと、第１折り返し部８１および第２折り返し部８６の対向方向（図７中の矢印１２２に示す方向）において第１折り返し部８１に近づきながら、シェル部４２の一方端４２ｊ側に向けて延びている。 In the state of the shell part 42 alone, the first folded part 81 is reversed from the shell part 42 into a substantially U shape, and then is opposed to the first folded part 81 and the second folded part 86 (in the direction of the arrow 122 in FIG. 7). In the direction shown), the shell portion 42 extends toward the one end 42j side while approaching the second folded portion 86. In the state of the shell part 42 alone, the second folded part 86 is reversed from the shell part 42 into a substantially U shape, and then is opposed to the first folded part 81 and the second folded part 86 (in the direction of the arrow 122 in FIG. 7). In the direction shown), the shell portion 42 extends toward the one end 42j while approaching the first folded portion 81.
　このような構成により、レセプタクル１０の組み立て工程時、シェル部４２の内側に舌部２２を挿入する際の作業性を向上させることができる。 With such a configuration, it is possible to improve workability at the time of inserting the tongue portion 22 inside the shell portion 42 during the assembly process of the receptacle 10.
　なお、第１折り返し部８１および第２折り返し部８６は、図９および図１０中に示す形状に限られない。たとえば、第１折り返し部８１および第２折り返し部８６は、シェル部４２の他方端４２ｋ側の端部から角部をなしながら反転された折り返し形状を有してもよい。 Note that the first folded portion 81 and the second folded portion 86 are not limited to the shapes shown in FIGS. 9 and 10. For example, the first folded portion 81 and the second folded portion 86 may have a folded shape that is inverted while forming a corner from the end of the shell portion 42 on the other end 42k side.
　図１１は、図９中のレセプタクルにプラグを接続した状態を示す断面図である。図１２は、図９中のレセプタクルにプラグを接続する工程を示す断面図である。 FIG. 11 is a cross-sectional view showing a state in which a plug is connected to the receptacle in FIG. 12 is a cross-sectional view showing a step of connecting a plug to the receptacle in FIG.
　図１１および図１２を参照して、プラグ７０は、外装体７１と、第１コンタクト７２と、第２コンタクト７３とを有する。 11 and 12, the plug 70 includes an exterior body 71, a first contact 72, and a second contact 73.
　外装体７１は、筒形状を有する。外装体７１は、一方向を向いて開口する開口部７１ｄを有する。 The exterior body 71 has a cylindrical shape. The exterior body 71 has an opening 71d that opens in one direction.
　第１コンタクト７２および第２コンタクト７３は、外装体７１に収容されている。第１コンタクト７２は、第１表面２１ａおよび第２表面２１ｂ上の電極群２４を構成する複数の電極に対応して設けられている。第２コンタクト７３は、第１表面２１ａおよび第２表面２１ｂ上の接地電極２３に対応して設けられている。開口部７１ｄから見て、第１コンタクト７２は、第２コンタクト７３よりも奥側に設けられ、第２コンタクト７３は、第１コンタクト７２よりも手前側に設けられている。 The first contact 72 and the second contact 73 are accommodated in the exterior body 71. The 1st contact 72 is provided corresponding to a plurality of electrodes which constitute electrode group 24 on the 1st surface 21a and the 2nd surface 21b. The second contact 73 is provided corresponding to the ground electrode 23 on the first surface 21a and the second surface 21b. When viewed from the opening 71 d, the first contact 72 is provided on the back side of the second contact 73, and the second contact 73 is provided on the near side of the first contact 72.
　第１コンタクト７２および第２コンタクト７３は、弾性変形可能に構成されている。レセプタクル１０に対するプラグ７０の接続時、第１コンタクト７２および第２コンタクト７３は、多層基板２１の第１表面２１ａおよび第２表面２１ｂに対して付勢力を作用させる。 The first contact 72 and the second contact 73 are configured to be elastically deformable. When the plug 70 is connected to the receptacle 10, the first contact 72 and the second contact 73 apply a biasing force to the first surface 21 a and the second surface 21 b of the multilayer substrate 21.
　プラグ７０をレセプタクル１０に接続すると、外装体７１が、挿入口１４を通じてシェル部４２の内部に進入するとともに、多層基板２１（より具体的には、舌部２２）が、開口部７１ｄを通じて外装体７１の内部に進入する。このとき、第１コンタクト７２が電極群２４に接触することによって、第１コンタクト７２および電極群２４の間が導通される。また、第２コンタクト７３が、第１折り返し部８１および第２折り返し部８６を介して接地電極２３に重ね合わされることによって、第２コンタクト７３および接地電極２３の間が導通される。 When the plug 70 is connected to the receptacle 10, the exterior body 71 enters the inside of the shell portion 42 through the insertion port 14, and the multilayer substrate 21 (more specifically, the tongue portion 22) passes through the opening 71 d. Enter inside 71. At this time, when the first contact 72 contacts the electrode group 24, the first contact 72 and the electrode group 24 are electrically connected. Further, the second contact 73 is superimposed on the ground electrode 23 via the first folded portion 81 and the second folded portion 86, whereby the second contact 73 and the ground electrode 23 are electrically connected.
　シェル部４２の第１折り返し部８１および第２折り返し部８６が、プラグ７０内部の第２コンタクト７３（グランドばね部）を挟んで接地電極２３により接地されているため、プラグ７０およびケーブルもシールドされる。すなわち、シェル部４２の第１折り返し部８１および第２折り返し部８６が、プラグ７０およびケーブルをシールドするためのＥＭＣパッドとしても機能する。 Since the first folded portion 81 and the second folded portion 86 of the shell portion 42 are grounded by the ground electrode 23 across the second contact 73 (ground spring portion) inside the plug 70, the plug 70 and the cable are also shielded. The That is, the first folded portion 81 and the second folded portion 86 of the shell portion 42 also function as an EMC pad for shielding the plug 70 and the cable.
　引き続いて、カバー４１の構造と、多層基板２１の支持構造とについて説明する。図２、図７および図８を参照して、カバー４１は、延出部４３をさらに有する。 Subsequently, the structure of the cover 41 and the support structure of the multilayer substrate 21 will be described. With reference to FIGS. 2, 7, and 8, cover 41 further includes an extending portion 43.
　延出部４３は、たとえば溶接によって、シェル部４２と一体とされている。延出部４３は、シェル部４２からその両側に延出するように設けられている。延出部４３は、シェル部４２から、図７中の矢印１２１に示す方向および矢印１２２に示す方向の双方に直交する矢印１２３に示す方向に延出している。 The extending portion 43 is integrated with the shell portion 42, for example, by welding. The extending portion 43 is provided so as to extend from the shell portion 42 to both sides thereof. The extending portion 43 extends from the shell portion 42 in the direction indicated by the arrow 123 that is orthogonal to both the direction indicated by the arrow 121 and the direction indicated by the arrow 122 in FIG.
　延出部４３は、シェル部４２の両側において多層基板２１に平行な板形状を有する。延出部４３には、ねじ挿入孔４６が形成されている。ねじ挿入孔４６は、延出部４３を貫通する貫通孔である。 The extending portion 43 has a plate shape parallel to the multilayer substrate 21 on both sides of the shell portion 42. A screw insertion hole 46 is formed in the extending portion 43. The screw insertion hole 46 is a through hole that penetrates the extending portion 43.
　第１突部２５および第２突部２８が、ケース１２（より具体的には、下ケース１２ｎ）に重ね合わされている。さらにその第１突部２５および第２突部２８に対して、延出部４３が平面的に重ね合わされている。延出部４３は、第１突部２５および第２突部２８における第１表面２１ａに面接触している。このとき、延出部４３に形成されたねじ挿入孔４６と、多層基板２１に形成されたねじ挿入孔２７とが、重なっている。 The first protrusion 25 and the second protrusion 28 are superimposed on the case 12 (more specifically, the lower case 12n). Further, the extending portion 43 is overlapped in a plane with respect to the first protrusion 25 and the second protrusion 28. The extending portion 43 is in surface contact with the first surface 21 a of the first protrusion 25 and the second protrusion 28. At this time, the screw insertion hole 46 formed in the extending portion 43 and the screw insertion hole 27 formed in the multilayer substrate 21 overlap.
　レセプタクル１０は、ねじ３６をさらに有する。ねじ３６は、金属から形成されている。ねじ３６は、多層基板２１の第１表面２１ａ側からねじ挿入孔４６およびねじ挿入孔２７に挿通され、ケース１２（より具体的には、下ケース１２ｎ）に螺合されている。このような構成により、多層基板２１は、ねじ３６によってケース１２に固定されている。カバー４１（延出部４３）は、ねじ３６によって、多層基板２１とともにケース１２に固定されている。 The receptacle 10 further has a screw 36. The screw 36 is made of metal. The screw 36 is inserted into the screw insertion hole 46 and the screw insertion hole 27 from the first surface 21a side of the multilayer substrate 21 and is screwed into the case 12 (more specifically, the lower case 12n). With such a configuration, the multilayer substrate 21 is fixed to the case 12 by the screws 36. The cover 41 (extending portion 43) is fixed to the case 12 together with the multilayer substrate 21 by screws 36.
　なお、本実施の形態では、多層基板２１をケース１２に固定する固定部材が、ねじ３６である場合を説明したが、これに限られず、たとえば、クリップやボルトが用いられてもよい。 In the present embodiment, the case where the fixing member that fixes the multilayer substrate 21 to the case 12 is the screw 36 has been described. However, the present invention is not limited thereto, and, for example, a clip or a bolt may be used.
　比較のため、電極群２４に対応するピン部材をシェル内に配置するとともに、半田を用いてそのピン部材を基板に固定するレセプタクルの構造を想定する。この場合、プラグの挿抜に伴って半田部分に応力が繰り返し加わるため、半田部分が破損する可能性がある。 For comparison, a receptacle structure is assumed in which a pin member corresponding to the electrode group 24 is disposed in the shell, and the pin member is fixed to the substrate using solder. In this case, since stress is repeatedly applied to the solder portion as the plug is inserted and removed, the solder portion may be damaged.
　これに対して、本実施の形態では、多層基板２１の舌部２２に電極群２４を設け、この舌部２２に対してプラグ７０を挿抜するため、レセプタクル１０が、プラグ７０の挿抜に対して高い耐久性（たとえば、１万回以上の挿抜に対する耐久性）を発揮することができる。また、このような構成により、多層基板２１がシェル部４２と同一の平面上に配置されるため、ケース１２を薄型化することができる。 On the other hand, in the present embodiment, the electrode group 24 is provided on the tongue portion 22 of the multilayer substrate 21 and the plug 70 is inserted into and removed from the tongue portion 22. High durability (for example, durability against 10,000 or more insertions / removals) can be exhibited. Moreover, since the multilayer substrate 21 is arrange | positioned on the same plane as the shell part 42 by such a structure, the case 12 can be reduced in thickness.
　さらに本実施の形態では、多層基板２１がねじ３６によってケース１２に固定されているため、プラグの挿抜に伴う応力を、多層基板２１がケース１２と一体となって受けることになる。これにより、プラグ７０の挿抜に対してさらに高い耐久性を発揮することができる。また、多層基板２１をケース１２に固定するねじ３６は、プラグ７０が挿抜される舌部２２に隣り合って設けられているため、プラグ７０の挿抜に対する耐久性をさらに高めることができる。 Further, in the present embodiment, since the multilayer substrate 21 is fixed to the case 12 by the screw 36, the multilayer substrate 21 receives the stress accompanying the insertion / extraction of the plug integrally with the case 12. Thereby, higher durability can be exhibited with respect to the insertion and removal of the plug 70. Further, since the screw 36 for fixing the multilayer substrate 21 to the case 12 is provided adjacent to the tongue portion 22 into which the plug 70 is inserted and removed, durability against the insertion and removal of the plug 70 can be further enhanced.
　カバー４１は、シールド部４４をさらに有する。シールド部４４は、たとえば溶接によって、シェル部４２と一体とされている。シールド部４４は、多層基板２１に実装された回路部品を覆うように設けられている。 The cover 41 further includes a shield part 44. The shield part 44 is integrated with the shell part 42, for example, by welding. The shield part 44 is provided so as to cover the circuit components mounted on the multilayer substrate 21.
　より具体的には、シールド部４４は、その構成部位として、底部４４ｐと、第１側部４４ｑおよび第２側部４４ｒとを有する。 More specifically, the shield part 44 has a bottom part 44p, a first side part 44q, and a second side part 44r as its constituent parts.
　底部４４ｐは、多層基板２１の第１表面２１ａと向かい合って配置されている。底部４４ｐは、シェル部４２の他方端４２ｋから連なっている。底部４４ｐは、放熱シート３２に接触している。第１側部４４ｑおよび第２側部４４ｒは、底部４４ｐの両端から立ち上がり、多層基板２１の第２表面２１ｂまで延在している。第１側部４４ｑおよび第２側部４４ｒは、図７中の矢印１２３に示す方向に対向して設けられている。 The bottom portion 44p is disposed to face the first surface 21a of the multilayer substrate 21. The bottom portion 44p continues from the other end 42k of the shell portion 42. The bottom 44p is in contact with the heat dissipation sheet 32. The first side portion 44q and the second side portion 44r rise from both ends of the bottom portion 44p and extend to the second surface 21b of the multilayer substrate 21. The first side portion 44q and the second side portion 44r are provided to face each other in the direction indicated by the arrow 123 in FIG.
　シールド部４４は、多層基板２１の第１表面２１ａ上において、ＤＣ／ＤＣコンバータ５０の構成部品のうちのＣｉｎ５４、メインスイッチ５５、ＳＲ５６およびＳＭＰＳコントローラ５７を覆うように設けられている。このような構成により、ＤＣ／ＤＣコンバータ５０の電磁シールドを簡易な構成により実現することができる。 The shield portion 44 is provided on the first surface 21a of the multilayer substrate 21 so as to cover the Cin 54, the main switch 55, the SR 56, and the SMPS controller 57 among the components of the DC / DC converter 50. With such a configuration, the electromagnetic shield of the DC / DC converter 50 can be realized with a simple configuration.
　以上に説明した、この発明の実施の形態におけるレセプタクル１０の構造についてまとめて説明すると、本実施の形態におけるレセプタクル１０は、プラグ７０を挿抜可能に構成されている。レセプタクル１０は、多層基板２１を備える。多層基板２１は、多層基板２１を平面視した場合の周縁に位置する舌部２２を有する。レセプタクル１０は、舌部２２において多層基板２１の両面に設けられる電極群２４と、多層基板２１に接続される金属製のカバー４１とを備える。カバー４１は、舌部２２を取り囲むように配置されるシェル部４２と、シェル部４２から多層基板２１の一方の面としての第１表面２１ａに近づくように折り返される折り返し形状を有し、弾性変形可能に構成される第１折り返し部８１と、第１折り返し部８１と対向して設けられ、シェル部４２から多層基板２１の他方の面としての第２表面２１ｂに近づくように折り返される折り返し形状を有し、弾性変形可能に構成される第２折り返し部８６とを有する。舌部２２は、第１折り返し部８１および第２折り返し部８６を互いに離れる方向に弾性変形させつつ、第１折り返し部８１および第２折り返し部８６の間に配置されている。 The structure of the receptacle 10 according to the embodiment of the present invention described above will be described together.
