In addition, in the printed board mounting structure described second, since two positioning ribs are provided on each enclosure wall, a space for providing positioning ribs around the printed board is required. There is a problem that the outer shape of the is increased. Further, in the printed circuit board mounting structure described at the end, there is a problem that an area where electronic components cannot be mounted on the printed circuit board or a pattern cannot be wired is generated by providing a hole for fitting a positioning pin on the printed circuit board. was there.

本発明は上記した従来の問題に鑑みなされたものであり、その目的とするところは、組付け時間を短縮し、プリント基板を実装する筺体の小型化を図るとともに、プリント基板に電子部品の搭載不可領域や配線パターンの不可領域を発生させないプリント基板の取付構造を提供するところにある。   The present invention has been made in view of the above-described conventional problems. The object of the present invention is to reduce the assembling time, reduce the size of the housing for mounting the printed circuit board, and mount electronic components on the printed circuit board. The present invention is to provide a printed circuit board mounting structure that does not generate an unusable area or an unusable area of a wiring pattern.

この目的を達成するために、請求項１に係る発明は、プリント基板を筺体に立設したスタッドにねじによって取り付けるプリント基板の取付構造であって、前記プリント基板の略中央部にねじを挿通する１個の挿通孔を設けるとともに、両端縁に略矩形状に形成した係合凸部を突設し、これら係合凸部の側部とプリント基板の外周縁とに同時に係合する係合部が設けられた互いに対向する一対の係合突起を筺体に立設し、前記一対の係合突起間の間隔を前記係合凸部の幅よりもわずかに大きく形成するとともに、前記互いに対向する係合突起の係合部間の間隔を前記プリント基板の両端縁間の長さよりもわずかに大きく形成したものである。 In order to achieve this object, the invention according to claim 1 is a printed circuit board mounting structure in which a printed circuit board is mounted on a stud erected on a housing by a screw, and the screw is inserted through a substantially central portion of the printed circuit board. provided with a single through hole, projecting the engagement convex portion formed in a substantially rectangular shape in both end edges, the engagement portion that engages simultaneously with the outer peripheral edge of the side and the printed circuit board of engaging protrusion A pair of opposing engaging projections provided with an erected portion are erected on the housing, and an interval between the pair of engaging projections is formed to be slightly larger than a width of the engaging projection, and the opposing engaging projections are formed. The interval between the engaging portions of the mating protrusions is formed to be slightly larger than the length between both end edges of the printed circuit board .

請求項２に係る発明は、請求項１に係る発明において、前記係合突起に前記プリント基板を載置する載置部を設けたものである。   The invention according to claim 2 is the invention according to claim 1, wherein a mounting portion for mounting the printed circuit board is provided on the engagement protrusion.

請求項１に係る発明によれば、プリント基板を位置決めした状態で１本のねじによって取り付けることができるため、組付け時間が短縮されるとともに作業性が向上する。また、係合突起をプリント基板の両端縁のみに設ければよいから、係合突起を設けるスペースが少なくなって、プリント基板が取り付けられる筺体の小型化を図ることができる。また、プリント基板に位置決め用の孔を設ける必要がないため、プリント基板に電子部品が搭載できない領域や配線パターンを形成できない領域が発生するようなこともない。   According to the first aspect of the present invention, since the printed circuit board can be attached with one screw in a positioned state, the assembling time is shortened and workability is improved. In addition, since the engagement protrusions only need to be provided at both ends of the printed circuit board, the space for providing the engagement protrusions is reduced, and the housing to which the printed circuit board is attached can be downsized. In addition, since there is no need to provide positioning holes in the printed circuit board, there is no occurrence of a region where electronic components cannot be mounted on the printed circuit board or a region where a wiring pattern cannot be formed.

In FIG. 4, reference numerals 16 to 19 denote engaging protrusions that protrude from the surrounding wall 11 so as to extend in the same direction as the axial direction of the stud 15. And mounting portions 16b to 19b.

プリント基板５は、図１に示すように略長方形に形成され、中央部に挿通孔２１が設けられており、両端縁には矩形状に形成した係合凸部２２，２３が突設されている。充電端子４，４は基端部がプリント基板５に取り付けられており、揺動端部にくの字状に折り曲げ形成された接触部４ａ，４ａが設けられている。   As shown in FIG. 1, the printed circuit board 5 is formed in a substantially rectangular shape, and is provided with an insertion hole 21 in the center portion. Engaging convex portions 22 and 23 formed in a rectangular shape are protruded from both end edges. Yes. The charging terminals 4 and 4 have base ends attached to the printed circuit board 5, and contact portions 4a and 4a which are bent and formed in a U shape at the swing end.

係合突起１６，１７間の間隔Ｗ２および係合突起１８，１９間の間隔Ｗ２は、図６に示すようにプリント基板５の凸部２２，２３の幅Ｗ１よりもわずかに大きく形成されている。また、係合突起１６の係合部１６ａと係合突起１９の係合部１９ａとの間隔Ｌ２および係合突起１７の係合部１７ａと係合突起１８の係合部１８ａとの間隔Ｌ２は、プリント基板５の係合凸部２２，２３が設けられている両端縁間の長さＬ１よりもわずかに大きく形成されている。   The interval W2 between the engagement protrusions 16 and 17 and the interval W2 between the engagement protrusions 18 and 19 are formed slightly larger than the width W1 of the convex portions 22 and 23 of the printed circuit board 5, as shown in FIG. . Further, the distance L2 between the engaging portion 16a of the engaging protrusion 16 and the engaging portion 19a of the engaging protrusion 19 and the distance L2 between the engaging portion 17a of the engaging protrusion 17 and the engaging portion 18a of the engaging protrusion 18 are as follows. The printed circuit board 5 is formed slightly larger than the length L1 between both end edges provided with the engaging convex portions 22 and 23.

次に、このように構成された充電台１においてプリント基板の取付方法について説明する。先ず、図４に示すようにその天地方向を逆向きとしたアッパーハウジング３のスタッド１５にプリント基板５の挿通孔２１を対向させ、図５に示すように、プリント基板５を４本の係合突起１６ないし１９の載置部１６ｂないし１９ｂ上に載置する。   Next, a method for attaching a printed circuit board in the charging stand 1 configured as described above will be described. First, as shown in FIG. 4, the insertion hole 21 of the printed circuit board 5 is made to face the stud 15 of the upper housing 3 whose top and bottom direction is reversed, and the four printed circuit boards 5 are engaged as shown in FIG. It mounts on the mounting parts 16b thru | or 19b of the processus | protrusions 16 thru | or 19.

この状態で、係合突起１６，１７間の間隔Ｗ２および係合突起１８，１９間の間隔Ｗ２が、図６に示すようにプリント基板５の凸部２２，２３の幅Ｗ１よりもわずかに大きく形成されており、係合部１６ａないし１９ａがプリント基板５の凸部２２，２３のそれぞれの側部２２ａ，２２ｂ，２３ａに係合する。同時に、係合突起１６の係合部１６ａと係合突起１９の係合部１９ａとの間隔Ｌ２および係合突起１７の係合部１７ａと係合突起１８の係合部１８ａとの間隔Ｌ２が、プリント基板５の係合凸部２２，２３が設けられている両端縁間の長さＬ１よりもわずかに大きく形成されており、係合部１６ａないし１９ａがプリント基板５の両端縁５ａないし５ｄに係合する。 In this state, the interval W2 between the engagement protrusions 16 and 17 and the interval W2 between the engagement protrusions 18 and 19 are slightly larger than the width W1 of the convex portions 22 and 23 of the printed circuit board 5, as shown in FIG. The engaging portions 16a to 19a are engaged with the side portions 22a, 22b, and 23a of the convex portions 22 and 23 of the printed circuit board 5, respectively. At the same time, an interval L2 between the engaging portion 16a of the engaging protrusion 16 and the engaging portion 19a of the engaging protrusion 19 and an interval L2 between the engaging portion 17a of the engaging protrusion 17 and the engaging portion 18a of the engaging protrusion 18 are set. The printed circuit board 5 is formed slightly larger than the length L1 between the both end edges provided with the engaging projections 22 and 23, and the engaging parts 16a to 19a are formed at the both end edges 5a to 5d of the printed circuit board 5. Engage with.

すなわち、これら係合突起１６ないし１９の係合部１６ａないし１９ａのそれぞれは、これら係合凸部２２，２３の各側部２２ａ，２２ｂ，２３ａ，２３ｂと、プリント基板５の各外周縁５ａないし５ｄとに同時に係合する。したがって、プリント基板５はこれら係合突起１６ないし１９によって左右・上下方向の位置決めがされるとともに、回動が規制された状態でアッパーハウジング３に仮止めされる。   That is, the engaging portions 16a to 19a of the engaging protrusions 16 to 19 are respectively connected to the side portions 22a, 22b, 23a, and 23b of the engaging convex portions 22 and 23 and the outer peripheral edges 5a to 5a of the printed circuit board 5. Engage with 5d simultaneously. Therefore, the printed circuit board 5 is positioned in the left and right and up and down directions by the engagement protrusions 16 to 19 and is temporarily fixed to the upper housing 3 in a state where the rotation is restricted.

次いで、プリント基板５の挿通孔２１にロアーハウジング２の挿通孔８を対向させるようにして、アッパーハウジング３の開口をロアーハウジング２によって覆い、ねじ２５を挿通孔８，２１に挿通させスタッド１５に螺合させることにより、図３に示すようにプリント基板５をスタッド１５に取り付ける。   Next, the insertion hole 8 of the lower housing 2 is made to face the insertion hole 21 of the printed circuit board 5, the opening of the upper housing 3 is covered with the lower housing 2, and the screw 25 is inserted into the insertion holes 8, 21 to the stud 15. By screwing, the printed circuit board 5 is attached to the stud 15 as shown in FIG.

このように、プリント基板５を係合突起１６ないし１９によって位置決めした状態で、１本のねじによってアッパーハウジング３に取り付けることができるため、組付け時間が短縮されるとともに作業性が向上する。また、係合突起１６ないし１９をプリント基板５の両端縁５ａないし５ｄのみに設ければよいから、係合突起１６ないし１９を設けるスペースが少なくなって、プリント基板５が取り付けられるアッパーハウジング３を小型化することができる。   Thus, since the printed circuit board 5 can be attached to the upper housing 3 with one screw in a state where the printed circuit board 5 is positioned by the engaging protrusions 16 to 19, the assembly time is shortened and workability is improved. Further, since the engaging protrusions 16 to 19 need only be provided at both end edges 5a to 5d of the printed circuit board 5, the space for providing the engaging protrusions 16 to 19 is reduced, and the upper housing 3 to which the printed circuit board 5 is attached is provided. It can be downsized.

また、プリント基板５に位置決め用の孔を設ける必要がないため、プリント基板５に電子部品が搭載できない領域やパターンを配線できない領域が発生するようなこともない。また、係合突起１６ないし１９に載置部１６ｂないし１９ｂを設けたことにより、プリント基板５を１本のねじ２５によって１つのスタッド１５に取り付けるのにもかかわらず、プリント基板５の取付状態が安定する。   Further, since there is no need to provide positioning holes in the printed circuit board 5, there is no occurrence of an area where electronic components cannot be mounted on the printed circuit board 5 or an area where patterns cannot be wired. In addition, since the mounting portions 16b to 19b are provided on the engaging protrusions 16 to 19, the mounting state of the printed circuit board 5 is maintained despite the fact that the printed circuit board 5 is attached to the single stud 15 with one screw 25. Stabilize.

なお、本実施の形態においては、ねじ２５によってプリント基板５とロアーハウジング２をスタッド１５に共締めするようにしたが、図８に示すようにプリント基板５のみをスタッド１５に取り付けるようにしてもよい。   In this embodiment, the printed circuit board 5 and the lower housing 2 are fastened to the stud 15 together with the screw 25. However, only the printed circuit board 5 may be attached to the stud 15 as shown in FIG. Good.
