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。   The best mode for carrying out the present invention will be described below 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 housing the 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 oriented in 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 direction in FIG. That is, the direction (direction A in FIG. 4) in which the opening into which the USB plug is inserted is directed in the USB socket 1 is referred to as an upward direction. In addition, the longitudinal direction of the USB socket 1 (the longitudinal direction as viewed from above and the CD direction in FIG. 4) is referred to as the left-right direction. Furthermore, the short direction of the USB socket 1 (the short direction as viewed from above, the EF direction in FIG. 4) is referred to as the front-rear direction. Note that the above directions are defined for convenience of explanation only, and in the normal use state, the above-described front-rear direction is directed to the up-down direction.

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。   Furthermore, 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 DC 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 are omitted. The circuit components constituting the AC-DC converter include the first printed wiring board 2 and the second printed wiring housed and held in the housing 3 so as to face the lower side of the first printed wiring board 2. The board 4 is mounted separately. 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。   The housing 3 includes a body 5 and a cover 6 that are coupled to each other in such a manner that the printed wiring boards 2 and 4 are sandwiched 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。   On each of the front and rear end faces of the body 5, two coupling projections 51 are provided so as to protrude outward in the front-rear direction, side by side. In addition, two connecting pieces 61 that sandwich the body 5 in the front-rear direction are provided on the front and rear ends of the cover 6 so as to protrude downward. Each coupling piece 61 is provided with a coupling hole 610 that is a through-hole penetrating in the front-rear direction, and the coupling projection 51 is engaged with each coupling hole 610 so that the body 5 and the cover 6 are mutually connected. 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 using the mounting frame 7 shown in FIGS. 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 are one box hole 72 for inserting a box screw to be screwed into an embedding box having a rounded rectangular shape and embedded in the construction surface. It is provided one by one. Further, on both sides sandwiching the box hole 72 in the short direction of the window hole 71, a clamp for sandwiching the panel material with the mounting frame 7 when the construction surface is formed of the panel material (see FIG. A catching hole 73 for catching and locking the notch is provided. Furthermore, circular direct attachment holes 74 for inserting direct attachment screws that are respectively screwed into the construction surface are provided at four positions sandwiching one hooking hole 73 with the window hole 71. Has been. Holding pieces 75 project from the both end edges in the short direction of the window hole 71, and three pairs of attachment holes 76 are provided in each holding piece 75 so as to be arranged in the longitudinal direction. Two pairs of mounting projections 31 that engage with the mounting holes 76 are provided on both front and rear surfaces of the housing 3. That is, the housing 3 is coupled to the mounting frame 7 by engaging each mounting projection 31 with 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。   The body 5 has a storage recess 50 that opens 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 that are released upward are provided at the upper ends of the inner surfaces facing the left and right sides of the storage recess 50. Two engaging projections 41 are provided on the left and right end portions of the second printed wiring board 4 so as to protrude outward in the left-right direction, arranged in the front-rear direction. The second printed wiring board 4 is prevented from being displaced downward or in the front-rear direction by the engagement convex portions 41 being in contact with the inner surfaces of the engagement concave portions 52. In other words, the second printed wiring board 4 is supported by the body 5 at each engagement convex portion 41. As shown in FIGS. 2, 3, and 11, two engagement projections 62 inserted into the engagement recesses 52 are arranged at the left and right ends of the cover 6, and are projected downward in the front-rear direction. It is installed. Each engagement convex portion 62 of the cover 6 sandwiches the engagement convex portion 41 of the second printed wiring board 4 between the upward facing inner surface of the engagement 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 W <b> 1 between the right engagement recesses 52 is set to be smaller than the distance W <b> 2 between the left engagement recesses 52. The distance between the right engaging projections 62 is substantially equal to the distance W1 between the right engaging recesses 52, and the distance between the left engaging projections 62 is equal to the distance W2 between the left engaging recesses 52. It is almost equal. Therefore, at the time of assembly, an operator temporarily puts the second printed wiring board 4 and the cover 6 180 degrees 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 orientation. When it is going to attach to the body 5 in the rotated wrong direction, the engaging convex parts 41 and 62 cannot be engaged with the engaging concave part 52. Thereby, the attachment in the above incorrect directions is prevented.

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。   Furthermore, two electric wire insertion holes 32 are provided on the lower surface of the body 5, and electric wires (not shown) inserted from the electric wire insertion holes 32 are connected to the lower surface of the second printed wiring board 4. Terminal 8 is mounted. The terminal 8 is a so-called quick connection terminal having two locking springs (not shown) that lock the electric wires inserted from the electric wire insertion holes 32 in one-to-one correspondence with the electric wire insertion holes 32. The terminal 8 has a release button 81 for releasing the lock by pressing each lock spring when pressed from below. The lower surface of the body 5 is provided with a release hole 33 (see FIG. 10) that exposes the release button 81 downward. For example, a jig (not shown) such as a minus driver is inserted into the release hole 33. With this, the release button 81 can be pressed.

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 portion 501 that stores the terminals 8 and a circuit storage portion 502 that stores other circuit components. Each electric wire insertion hole 32 and the release hole 33 are opened on the bottom surface of the terminal storage portion 501.

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。   Furthermore, the left and right ends of the body 5 support the first printed wiring board 2 (that is, abut the lower surface of the first printed wiring board 2 opposite to the surface on which the USB socket 1 is mounted). The support convex part 53 is projected upward. At the upper end of each support projection 53, a support recess 530 that is released in the left-right direction is provided. Further, leg portions 21 project outwardly in the left-right direction on both sides of the first printed wiring board 2 sandwiching the USB socket 1 in the longitudinal direction (left-right direction) as viewed from above. The first printed wiring board 2 is prevented from being displaced in the front-rear direction or in the downward direction by accommodating the leg portions 21 in the support recesses 530, respectively. 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 against the central portion of the lower surface of the first printed wiring board 2 (that is, near 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 contacts the first printed wiring board 2, so that the center portion of the first printed wiring board 2 is lowered with respect to the leg portion 21. The bending (deformation) of the first printed wiring board 2 that is displaced in the direction 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, the 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.

以上説明したように、第1の態様に係るUSBコンセントは、USBソケット1が実装された第1プリント配線板2と、USBソケット1に接続されるUSBプラグが挿通されるプラグ挿通穴30を有して第1プリント配線板2を収納するハウジング3と、を備える。ハウジング3は、上下方向において互いに結合するボディ5とカバー6と、を備える。ボディ5は上方に開口した収納凹部50を有し、カバー6はプラグ挿通穴30を有する。USBコンセントは、第1プリント配線板2の下側に対向する形で収納凹部50に収納される第2プリント配線板4をさらに備える。収納凹部50は、一方向に対向する一対の内面を有する。収納凹部50において一対の内面の上端には、それぞれ、上方に開放された係合凹部52が設けられる。第2プリント配線板4の一方向の両端部にはそれぞれ係合凸部41が一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、係合凸部41をそれぞれ係合凹部52の内面に当接させることで、ボディ5に支持されている。   As described above, the USB outlet according to the first aspect has the first printed wiring board 2 on which the USB socket 1 is mounted and the plug insertion hole 30 through which the USB plug connected to the USB socket 1 is inserted. And a housing 3 that houses the first printed wiring board 2. The housing 3 includes a body 5 and a cover 6 that are coupled to each other in the vertical direction. The body 5 has a storage recess 50 opened upward, and the cover 6 has a plug insertion hole 30. The USB outlet further includes a second printed wiring board 4 that is stored in the storage recess 50 so as to face the lower side of the first printed wiring board 2. The storage recess 50 has a pair of inner surfaces facing in one direction. Engagement recesses 52 opened upward are respectively provided at the upper ends of the pair of inner surfaces of the storage recess 50. Engaging convex portions 41 are provided so as to project outward in one direction at both ends in one direction of the second printed wiring board 4. The second printed wiring board 4 is supported by the body 5 by bringing the engaging convex portions 41 into contact with the inner surfaces of the engaging concave portions 52.

第2の態様に係るUSBコンセントは、第1の態様において、カバー6の一方向の両端部には、それぞれ、係合凹部52に挿入される第1係合凸部62が下方へ突設されている。第2プリント配線板4の係合凸部41である第2係合凸部41は、第1係合凸部62と係合凹部52の上向きの内面との間に挟まれている。   In the USB outlet according to the second aspect, in the first aspect, the first engaging convex part 62 inserted into the engaging concave part 52 protrudes downward at both ends of the cover 6 in one direction. ing. The second engagement protrusion 41 that is the engagement protrusion 41 of the second printed wiring board 4 is sandwiched between the first engagement protrusion 62 and the upward inner surface of the engagement recess 52.

第3の態様に係るUSBコンセントは、第1または2の態様において、一対の内面の上端には、それぞれ、係合凹部52が2個ずつ設けられている。一対の内面のうち一方側の内面における2個の係合凹部52間の距離W1は、他方側の内面における2個の係合凹部52間の距離W2よりも小さい。   In the USB outlet according to the third aspect, in the first or second aspect, two engaging recesses 52 are respectively provided at the upper ends of the pair of inner surfaces. The distance W1 between the two engaging recesses 52 on the inner surface on one side of the pair of inner surfaces is smaller than the distance W2 between the two engaging recesses 52 on the inner surface on the other side.
