以下、本発明を実施するための最良の形態について、図面を参照しながら説明する。 Hereinafter, the best mode for carrying out the present invention will be described with reference to the drawings.

本実施形態は、図１〜図９に示すように、ＵＳＢソケット１が実装されたプリント配線板（以下、「第１プリント配線板」と呼ぶ。）２と、ＵＳＢソケット１に接続されるＵＳＢプラグ（図示せず）が挿通されるプラグ挿通穴３０を有してプリント配線板２を収納するハウジング３とを備える。ＵＳＢソケット１は、ＵＳＢプラグが挿抜される方向を第１プリント配線板２の厚さ方向に向けて第１プリント配線板２に実装されている。 In this embodiment, as shown in FIGS. 1 to 9, a printed wiring board (hereinafter, referred to as “first printed wiring board”) 2 on which the USB socket 1 is mounted and a USB connected to the USB socket 1 A housing 3 having a plug insertion hole 30 through which a plug (not shown) is inserted and accommodating a printed wiring board 2 is provided. The USB socket 1 is mounted on the first printed wiring board 2 with the direction in which the USB plug is inserted and removed toward the thickness direction of the first printed wiring board 2.

以下、図４のＡＢＣＤＥＦ方向を、それぞれ、上下左右前後方向と呼ぶ。すなわち、ＵＳＢソケット１においてＵＳＢプラグが挿入される開口が向けられた方向（図４でのＡ方向）を上方向と呼ぶ。また、ＵＳＢソケット１の長手方向（上記の上方向から見た長手方向であり、図４でのＣＤ方向）を左右方向と呼ぶ。さらに、ＵＳＢソケット１の短手方向（上記の上方向から見た短手方向であり、図４でのＥＦ方向）を前後方向と呼ぶ。なお、上記の方向はあくまで説明の便宜上定義するものであって、通常の使用状態では上記の前後方向が上下方向に向けられる。 Hereinafter, the ABCDEF directions in FIG. 4 are referred to as up / down / left / right / front / rear directions, respectively. That is, the direction in which the opening in which the USB plug is inserted in the USB socket 1 is directed (A direction in FIG. 4) is referred to as an upward direction. Further, the longitudinal direction of the USB socket 1 (the longitudinal direction seen from above and the CD direction in FIG. 4) is referred to as a left-right direction. Further, the lateral direction of the USB socket 1 (the lateral direction seen from above and the EF direction in FIG. 4) is referred to as a front-rear direction. It should be noted that the above-mentioned direction is defined only for convenience of explanation, and the above-mentioned front-back direction is directed to the up-down direction in a normal use state.

さらに、本実施形態は、外部の交流電源から入力された交流電力を所定電圧の直流電力に変換してＵＳＢソケット１を介して上記のＵＳＢプラグに出力するＡＣ−ＤＣコンバータを備える。上記のようなＡＣ−ＤＣコンバータは周知技術で実現可能であるので、詳細な図示並びに説明は省略する。上記のＡＣ−ＤＣコンバータを構成する回路部品は、上記の第１プリント配線板２と、第１プリント配線板２の下側に対向する形でハウジング３内に収納及び保持される第２プリント配線板４とに分けて実装されている。第１プリント配線板２と第２プリント配線板４とは例えば導電ピンのような適宜の導電路４０を介して互いに電気的に接続されている。 Further, the present embodiment includes an AC-DC converter that converts AC power input from an external AC power source into DC power having a predetermined voltage and outputs the AC power to the USB plug via the USB socket 1. Since the AC-DC converter as described above can be realized by a well-known technique, detailed illustration and description will be omitted. The circuit components constituting the AC-DC converter are housed and held in the housing 3 so as to face the first printed wiring board 2 and the lower side of the first printed wiring board 2. It is mounted separately from the plate 4. The first printed wiring board 2 and the second printed wiring board 4 are electrically connected to each other via an appropriate conductive path 40 such as a conductive pin.

また、ハウジング３は、各プリント配線板２，４をそれぞれ厚さ方向（上下方向）において挟む形で互いに結合するボディ５とカバー６とを備える。 Further, the housing 3 includes a body 5 and a cover 6 which are connected to each other by sandwiching the printed wiring boards 2 and 4 in the thickness direction (vertical direction).

ボディ５の前後両端面には、それぞれ２個ずつの結合凸部５１が左右に並べて前後方向の外向きに突設されている。また、カバー６の前後両端部には、それぞれ、前後方向においてボディ５を挟む２個ずつの結合片６１が下方に突設されている。各結合片６１にはそれぞれ前後方向に貫通した貫通穴である結合穴６１０が設けられており、各結合穴６１０にそれぞれ結合凸部５１が係入することで、ボディ５とカバー６とは互いに結合する。 Two coupling convex portions 51 are arranged side by side on both front and rear end surfaces of the body 5 so as to project outward in the front-rear direction. Further, at both front and rear ends of the cover 6, two connecting pieces 61 sandwiching the body 5 in the front-rear direction are projected downward. Each coupling piece 61 is provided with a coupling hole 610 which is a through hole penetrating in the front-rear direction. Join.

ハウジング３は、図８及び図９に示す取付枠７を用いて、壁面等の施工面（図示せず）に固定される。取付枠７は矩形状の窓穴７１を有する矩形枠状である。窓穴７１の長手方向における取付枠７の両端部には、角丸長方形状であって施工面に埋めこまれた埋込ボックスに螺合するボックスねじを挿入するためのボックス用穴７２が１個ずつ設けられている。また、窓穴７１の短手方向においてボックス用穴７２を挟む両側には、施工面がパネル材で形成されているときに取付枠７との間でパネル材を挟みこむための挟み金具（図示せず）を引掛け係止するための引掛穴７３が貫設されている。さらに、窓穴７１との間に１個ずつの引掛穴７３を挟む４箇所には、それぞれ施工面に螺合する直付け用ねじを挿入するための円形状の直付け用穴７４が貫設されている。窓穴７１の短手方向の両端縁には
それぞれ保持片７５が突設されており、各保持片７５にはそれぞれ３対ずつ取付穴７６が長手方向に沿って並ぶように設けられている。ハウジング３の前後両面には、それぞれ取付穴７６に係入する取付凸部３１が２対ずつ設けられている。すなわち、各取付凸部３１がそれぞれ取付穴７６に係入することで、ハウジング３は取付枠７に結合する。 The housing 3 is fixed to a construction surface (not shown) such as a wall surface by using the mounting frame 7 shown in FIGS. 8 and 9. The mounting frame 7 has a rectangular frame shape having a rectangular window hole 71. At both ends of the mounting frame 7 in the longitudinal direction of the window hole 71, there is one box hole 72 for inserting a box screw that has a rectangular shape with rounded corners and is screwed into an embedded box embedded in the construction surface. It is provided one by one. Further, on both sides of the box hole 72 in the lateral direction of the window hole 71, sandwiching metal fittings for sandwiching the panel material with the mounting frame 7 when the construction surface is formed of the panel material (FIG. FIG. A hook hole 73 for hooking and locking (not shown) is provided. Further, circular direct mounting holes 74 for inserting direct mounting screws to be screwed into the construction surface are pierced at four locations where one hook hole 73 is sandwiched between the window hole 71 and the window hole 71. Has been done. Holding pieces 75 are projected from both ends of the window hole 71 in the lateral direction, and three pairs of mounting holes 76 are provided in each holding piece 75 so as to be arranged along the longitudinal direction. Two pairs of mounting convex portions 31 engaging in the mounting holes 76 are provided on both the front and rear surfaces of the housing 3. That is, the housing 3 is coupled to the mounting frame 7 by engaging each mounting convex portion 31 into the mounting hole 76.

また、ボディ５は上方に開口した収納凹部５０を有し、第２プリント配線板４は収納凹部５０に収納される。さらに、図２，図３及び図１０に示すように、収納凹部５０において左右に対向する内面の上端には、それぞれ、上方に解放された２個ずつの係合凹部５２が設けられている。第２プリント配線板４の左右両端部にはそれぞれ２個ずつの係合凸部４１が前後に並べて左右方向の外向きに突設されている。第２プリント配線板４は、各係合凸部４１がそれぞれ係合凹部５２の内面に当接することで下方や前後方向への位置ずれを防止される。言い換えると、第２プリント配線板４は各係合凸部４１においてボディ５に支持されている。また、図２，図３及び図１１に示すように、カバー６の左右両端部には、それぞれ係合凹部５２に挿入される２個ずつの係合凸部６２が、前後に並べて下方へ突設されている。カバー６の各係合凸部６２は、それぞれ、係合凹部５２の上向きの内面との間に第２プリント配線板４の係合凸部４１を挟む。 Further, the body 5 has a storage recess 50 opened upward, and the second printed wiring board 4 is stored in the storage recess 50. Further, as shown in FIGS. 2, 3 and 10, two engaging recesses 52 opened upward are provided at the upper ends of the inner surfaces of the storage recesses 50 facing each other on the left and right sides. At the left and right ends of the second printed wiring board 4, two engaging convex portions 41 are arranged one by one in the front-rear direction and are projected outward in the left-right direction. The second printed wiring board 4 is prevented from being displaced downward or in the front-rear direction by having each engaging convex portion 41 abut on the inner surface of the engaging concave portion 52. In other words, the second printed wiring board 4 is supported by the body 5 at each engaging convex portion 41. Further, as shown in FIGS. 2, 3 and 11, two engaging protrusions 62 inserted into the engaging recesses 52 are arranged in front and back and protrude downward at both left and right ends of the cover 6. It is installed. Each engaging convex portion 62 of the cover 6 sandwiches the engaging convex portion 41 of the second printed wiring board 4 between the engaging concave portion 52 and the upward inner surface of the engaging concave portion 52.

ここで、右側の係合凹部５２間の距離Ｗ１は、左側の係合凹部５２間の距離Ｗ２よりも小さくされている。また、右側の係合凸部６２間の距離は右側の係合凹部５２間の距離Ｗ１とほぼ等しくされ、左側の係合凸部６２間の距離は左側の係合凹部５２間の距離Ｗ２とほぼ等しくされている。従って、組立時、仮に、作業者が、第２プリント配線板４やカバー６を、正しい向きに対して上下方向（すなわち第２プリント配線板４の厚さ方向）に平行な軸周りに１８０°回転した誤った向きでボディ５に取り付けようとした場合、係合凸部４１，６２を係合凹部５２に係合させることができない。これにより、上記のような誤った向きでの取り付けが防止される。 Here, the distance W1 between the engaging recesses 52 on the right side is smaller than the distance W2 between the engaging recesses 52 on the left side. Further, the distance between the engaging protrusions 62 on the right side is substantially equal to the distance W1 between the engaging recesses 52 on the right side, and the distance between the engaging protrusions 62 on the left side is the distance W2 between the engaging recesses 52 on the left side. It is almost equal. Therefore, at the time of assembly, the operator temporarily attaches the second printed wiring board 4 and the cover 6 to 180 ° around an axis parallel to the vertical direction (that is, the thickness direction of the second printed wiring board 4) with respect to the correct direction. When trying to attach to the body 5 in the wrong direction of rotation, the engaging protrusions 41 and 62 cannot be engaged with the engaging recess 52. This prevents mounting in the wrong orientation as described above.

さらに、ボディ５の下面には２個の電線挿入穴３２が設けられていて、第２プリント配線板４の下面には、電線挿入穴３２から挿入された電線（図示せず）が接続される端子８が実装されている。端子８は、電線挿入穴３２から挿入された電線を鎖錠する鎖錠ばね（図示せず）を電線挿入穴３２に一対一に対応して２個有する、いわゆる速結端子である。また、端子８は、下方から押圧されたときに各鎖錠ばねをそれぞれ押圧することで鎖錠を解除する解除釦８１を有する。ボディ５の下面には、解除釦８１を下方に露出させる解除穴３３（図１０参照）が設けられており、例えばマイナスドライバのような治具（図示せず）を解除穴３３に挿入することで解除釦８１を押操作することができる。 Further, two electric wire insertion holes 32 are provided on the lower surface of the body 5, and an electric wire (not shown) inserted from the electric wire insertion hole 32 is connected to the lower surface of the second printed wiring board 4. Terminal 8 is mounted. The terminal 8 is a so-called quick-connect terminal having two locking springs (not shown) for locking the electric wire inserted from the electric wire insertion hole 32 in a one-to-one correspondence with the electric wire insertion hole 32. Further, the terminal 8 has a release button 81 that releases the lock by pressing each lock spring when pressed from below. A release hole 33 (see FIG. 10) for exposing the release button 81 downward is provided on the lower surface of the body 5, and a jig (not shown) such as a flat-blade screwdriver is inserted into the release hole 33. The release button 81 can be pressed and operated with.

また、ボディ５は、収納凹部５０を、端子８が収納される端子収納部５０１と、その他の回路部品が収納される回路収納部５０２とに仕切る仕切り壁５４を有する。各電線挿入穴３２と解除穴３３とはそれぞれ端子収納部５０１の底面に開口している。 The body 5 also has a partition wall 54 that partitions the storage recess 50 into a terminal storage section 501 in which the terminals 8 are stored and a circuit storage section 502 in which other circuit components are stored. Each electric wire insertion hole 32 and release hole 33 are opened on the bottom surface of the terminal storage portion 501, respectively.

さらに、ボディ５の左右両端部には、それぞれ、第１プリント配線板２を支持する（つまり、第１プリント配線板２においてＵＳＢソケット１が実装された面の反対面である下面に当接する）支持凸部５３が上方へ突設されている。各支持凸部５３の上端には、それぞれ左右方向に解放された支持凹部５３０が設けられている。さらに、第１プリント配線板２の左右両端部において上方から見てＵＳＢソケット１を長手方向（左右方向）において挟む両側には、それぞれ脚部２１が左右方向の外向きに突設されている。第１プリント配線板２は、各脚部２１がそれぞれ支持凹部５３０に収納されることで、前後方向や下方への位置ずれを防止される。言い換えると、第１プリント配線板２は脚部２１においてボディ５の支持凸部５３に支持されている。 Further, the first printed wiring board 2 is supported on each of the left and right ends of the body 5 (that is, the first printed wiring board 2 abuts on the lower surface opposite to the surface on which the USB socket 1 is mounted). The support convex portion 53 is projected upward. At the upper end of each support convex portion 53, a support concave portion 530 opened in the left-right direction is provided. Further, leg portions 21 are projected outward in the left-right direction on both left and right ends of the first printed wiring board 2 sandwiching the USB socket 1 in the longitudinal direction (left-right direction) when viewed from above. The first printed wiring board 2 is prevented from being displaced in the front-rear direction or downward by storing each leg 21 in the support recess 530. In other words, the first printed wiring board 2 is supported by the support convex portion 53 of the body 5 at the leg portion 21.

また、仕切り壁５４の上端には、第２プリント配線板４に設けられた挿通穴４２に挿通
されて第１プリント配線板２の下面の中央部（すなわちＵＳＢソケット１の近傍）に当接する当接部５５が設けられている。すなわち、ＵＳＢプラグがＵＳＢソケット１に接続される際には、当接部５５が第１プリント配線板２に当接することで、第１プリント配線板２の中央部を脚部２１に対して下方に変位させるような第１プリント配線板２の曲がり（変形）が抑えられる。 Further, the upper end of the partition wall 54 is inserted into an insertion hole 42 provided in the second printed wiring board 4 and abuts on the central portion of the lower surface of the first printed wiring board 2 (that is, in the vicinity of the USB socket 1). A contact portion 55 is provided. That is, when the USB plug is connected to the USB socket 1, the contact portion 55 comes into contact with the first printed wiring board 2, so that the central portion of the first printed wiring board 2 is lowered with respect to the leg portion 21. Bending (deformation) of the first printed wiring board 2 that displaces the first printed wiring board 2 is suppressed.

上記構成によれば、当接部５５が設けられない場合に比べ、ＵＳＢプラグが接続される際の第１プリント配線板２の曲がりが抑えられる。 According to the above configuration, bending of the first printed wiring board 2 when the USB plug is connected can be suppressed as compared with the case where the contact portion 55 is not provided.
