Description

本発明は、電動工具等に取り付けられるＬＥＤ（発光ダイオード）を固定するためのＬＥＤホルダーに関するものである。   The present invention relates to an LED holder for fixing an LED (light emitting diode) attached to an electric tool or the like.

最近の電動工具においては、ＬＥＤを用いるものが多くなっている。このＬＥＤを取り付けるためのＬＥＤホルダーとしては、例えば、ＬＥＤを囲む「コ」の字型の壁と、この壁の底面から設けられた一対の爪部及び一対のガイドピンとを有するものが提案されている（例えば、特許文献１参照）。
特開２００５−３１１１０２公報 In recent power tools, many use LED. As an LED holder for attaching this LED, for example, an LED holder having a “U” -shaped wall surrounding the LED and a pair of claw portions and a pair of guide pins provided from the bottom of the wall has been proposed. (For example, refer to Patent Document 1).
JP 2005-311102 A

上記のようなＬＥＤホルダーは、一対の爪部とガイドピンをプリント配線基板に差し込むだけで固定ができるため組み立て工程が簡単となる。しかし、ＬＥＤを「コ」の字型の壁の上方から差し込む構造であるため、電動工具のように振動が多く発生するものにおいてはＬＥＤが、この壁から外れたりすることがある。   Since the LED holder as described above can be fixed simply by inserting the pair of claw portions and the guide pins into the printed wiring board, the assembly process is simplified. However, since the LED is inserted from above the “U” -shaped wall, the LED may be detached from the wall in a case where a lot of vibration is generated like an electric tool.

そこで、本発明は上記問題点に鑑み、プリント配線基板に容易に取り付けることができ、かつ、ＬＥＤが振動等によっても外れないＬＥＤホルダーを提供する。   Therefore, in view of the above problems, the present invention provides an LED holder that can be easily attached to a printed wiring board and that the LED does not come off due to vibration or the like.

請求項１に係る発明は、ＬＥＤをプリント配線基板に取り付けるためのＬＥＤホルダーにおいて、前記ＬＥＤの後部が差し込まれる挿入孔を有するＬＥＤ固定部と、前記ＬＥＤ固定部の底面から突出し、前記プリント配線基板の一対の固定孔に差し込まれる一対の爪部と、前記ＬＥＤ固定部に貫通した配線孔と、有することを特徴とするＬＥＤホルダーである。   The invention according to claim 1 is an LED holder for attaching an LED to a printed wiring board, wherein the LED fixing part has an insertion hole into which the rear part of the LED is inserted, and protrudes from the bottom surface of the LED fixing part, and the printed wiring board It has a pair of nail | claw part inserted in a pair of fixing hole of this, and the wiring hole penetrated to the said LED fixing | fixed part, It is an LED holder characterized by the above-mentioned.

請求項２に係る発明は、前記ＬＥＤの後部が前記ＬＥＤ固定部に軸方向に差し込まれることを特徴とする請求項１記載のＬＥＤホルダーである。   The invention according to claim 2 is the LED holder according to claim 1, wherein the rear portion of the LED is inserted into the LED fixing portion in the axial direction.

請求項３に係る発明は、前記一対の爪部が平行に配置されていることを特徴とする請求項１記載のＬＥＤホルダーである。   The invention according to claim 3 is the LED holder according to claim 1, wherein the pair of claw portions are arranged in parallel.

請求項４に係る発明は、前記一対の爪部がハの字状に配置されていることを特徴とする請求項１記載のＬＥＤホルダーである。   The invention according to claim 4 is the LED holder according to claim 1, wherein the pair of claw portions are arranged in a square shape.

請求項５に係る発明は、前記プリント配線基板が、電動工具に内部に設けられていることを特徴とする請求項１記載のＬＥＤホルダーである。   The invention according to claim 5 is the LED holder according to claim 1, wherein the printed wiring board is provided inside an electric tool.

本発明によれば、簡単にプリント配線基板に取り付けることができ、かつ、ＬＥＤがＬＥＤホルダーから外れることがない。   According to the present invention, the LED can be easily attached to the printed wiring board, and the LED is not detached from the LED holder.

以下、本発明の一実施形態のＬＥＤホルダー１０について図面に基づいて説明する。   Hereinafter, an LED holder 10 according to an embodiment of the present invention will be described with reference to the drawings.

（第１の実施形態）
以下、本発明の第１の実施形態のＬＥＤホルダー１０について図１〜図３に基づいて説明する。 (First embodiment)
Hereinafter, the LED holder 10 of the 1st Embodiment of this invention is demonstrated based on FIGS. 1-3.

本実施形態のＬＥＤホルダー１０は、電動工具の内部、具体的には、電動工具のフレーム内部にあるブラシレスＤＣモータの下方に取り付けられたプリント配線基板１２にＬＥＤ１４を固定するためのものである。   The LED holder 10 of the present embodiment is for fixing the LED 14 to the printed wiring board 12 attached to the inside of the electric tool, specifically, the brushless DC motor inside the frame of the electric tool.

ＬＥＤホルダー１０は、合成樹脂により一体成形され、ＬＥＤ１４を固定するためのＬＥＤ固定部１６と、このＬＥＤ固定部１６の底面から突出した一対の爪部１８とから構成されている。   The LED holder 10 is integrally formed of a synthetic resin, and includes an LED fixing portion 16 for fixing the LED 14 and a pair of claw portions 18 protruding from the bottom surface of the LED fixing portion 16.

ＬＥＤ固定部１６の前面には挿入孔２０が開口し、ＬＥＤ１４の後部を軸方向に挿入してその後部を完全に覆って固定する。また、この挿入孔２０の閉塞面には、ＬＥＤ１４から突出している配線用の脚２２、２２が貫通する配線孔２４、２４が貫通している。この配線孔２４は、挿入孔２０の閉塞面からＬＥＤ固定部１６の後面に貫通し、ＬＥＤ１４を固定した場合に脚２２が配線孔２４の後面から突出し、図１に示すようにプリント配線基板１２の上面に半田付けで固定できる。   An insertion hole 20 is opened on the front surface of the LED fixing portion 16, and the rear portion of the LED 14 is inserted in the axial direction to completely cover and fix the rear portion. In addition, wiring holes 24, 24 through which wiring legs 22, 22 projecting from the LED 14 pass are passed through the closing surface of the insertion hole 20. The wiring hole 24 penetrates from the closed surface of the insertion hole 20 to the rear surface of the LED fixing portion 16, and when the LED 14 is fixed, the leg 22 protrudes from the rear surface of the wiring hole 24. As shown in FIG. Can be fixed to the upper surface of the solder by soldering.

一対の爪部１８，１８は、プリント配線基板１２の所定の箇所に開口した一対の固定孔２６，２６に係合してＬＥＤホルダー１０を固定する。   The pair of claw portions 18 and 18 are engaged with a pair of fixing holes 26 and 26 opened at predetermined positions of the printed wiring board 12 to fix the LED holder 10.

上記構成のＬＥＤホルダー１０であると、一対の爪部１８のみによってＬＥＤホルダー１０を取り付けるため、取り付け作業が容易であり、その取り付け位置を容易に確保することができる。また、ＬＥＤホルダー１０の傾きや浮き、ズレ等をなくすことができる。   In the case of the LED holder 10 having the above-described configuration, the LED holder 10 is attached only by the pair of claws 18, so that the attaching operation is easy and the attaching position can be easily secured. In addition, the LED holder 10 can be prevented from tilting, floating, shifting, and the like.

さらに、ＬＥＤ１４は、ＬＥＤ固定部１６の挿入孔２０に挿入して固定する構造であるため、電動工具のように振動が有るものであってもＬＥＤ１４がＬＥＤホルダー１０から外れたりすることがない。   Furthermore, since the LED 14 is structured to be inserted and fixed in the insertion hole 20 of the LED fixing portion 16, the LED 14 does not come off the LED holder 10 even if there is vibration like an electric power tool.

（第２の実施形態）
次に、図４に基づいて第２の実施形態のＬＥＤホルダー１０について説明する。 (Second Embodiment)
Next, the LED holder 10 of 2nd Embodiment is demonstrated based on FIG.

本実施形態のＬＥＤホルダー１０と第１の実施形態のＬＥＤホルダー１０の相違点は、一対の爪部１８，１８の構造にある。即ち、第１の実施形態では一対の爪部１８，１８は平行に設けられていたが、本実施形態では図４に示すように「ハ」の字状に構成されている。そして、図４に示すようにプリント配線基板１２に設けられている一対の固定孔２６については、この「ハ」の字状の爪部１８，１８が斜めに挿入できる大きさに開口している。   The difference between the LED holder 10 of the present embodiment and the LED holder 10 of the first embodiment is in the structure of the pair of claw portions 18 and 18. That is, in the first embodiment, the pair of claw portions 18 and 18 are provided in parallel, but in this embodiment, as shown in FIG. As shown in FIG. 4, the pair of fixing holes 26 provided in the printed wiring board 12 are opened to a size that allows the “c” -shaped claw portions 18, 18 to be inserted obliquely. .

このような「ハ」の字状の一対の爪部１８，１８であると、ＬＥＤホルダー１０を平行な場合よりより安定して固定することができる。その上、一対の爪部１８，１８の寸法及び一対の固定孔２６，２６の寸法精度が第１の実施形態のものよりも低くても、確実に固定することができる。   With such a pair of claw portions 18 and 18 having a “C” shape, the LED holder 10 can be fixed more stably than when parallel. In addition, even if the dimensions of the pair of claw portions 18 and 18 and the dimensional accuracy of the pair of fixing holes 26 and 26 are lower than those of the first embodiment, they can be reliably fixed.

本発明のＬＥＤホルダーは、電動工具、空気調和機、その他の電気機器に使用することができる。   The LED holder of the present invention can be used for electric tools, air conditioners, and other electric devices.

本発明の第１の実施形態を示すＬＥＤホルダーの側面図である。It is a side view of the LED holder which shows the 1st Embodiment of this invention. 同じくＬＥＤホルダーの正面図である。It is a front view of a LED holder similarly. 同じくＬＥＤホルダーをプリント配線基板に取り付けた状態の底面図である。It is a bottom view of the state which similarly attached the LED holder to the printed wiring board. 第２の実施形態のＬＥＤホルダーの底面図である。It is a bottom view of the LED holder of 2nd Embodiment.
