Is a power tool in which a control circuit for controlling drive of a motor provided in the power tool body is incorporated in a circuit holding part in the battery pack mounting part, and is mounted on at least a lower surface of the control circuit. A bulging portion is formed in part, and an opening window is formed on the lower surface of the battery pack mounting portion exposed to the battery pack side, and the bulging portion is inserted into the opening window so that the control circuit Built and configured.
本発明によれば、制御回路を相対的に大きく構成しても、電動工具全体の大型化への影響を極力小さく留める内部構造とした電動工具を提供することができる。 ADVANTAGE OF THE INVENTION According to this invention, even if it comprises a control circuit relatively large, the electric tool made into the internal structure which keeps the influence on the enlargement of the whole electric tool as much as possible can be provided.

Hereinafter, an embodiment of a power tool will be described with reference to the drawings.
As shown in FIG. 1, the power tool 10 of the present embodiment is a hand-held and rechargeable power tool that an operator can hold with one hand, and is attachable to and detachable from the power tool body 11 and the power tool body 11.

The housing 13 forming the outline of the electric power tool body 11 has a cylindrical body portion 14 and a grip portion 15 extending downward from the middle of the body portion 14 in the front-rear direction (longitudinal direction). A battery pack mounting portion 16 for mounting the battery pack 12 is provided below the grip portion 15.
ハウジング１３の胴部１４の後側には、動力源としてモータ２０が備えられている。モータ２０は、ハウジング１３の胴部１４の前側に配置されるトルク増幅器２１を介して電動工具１０の出力軸２２と駆動連結されており、この出力軸２２の先端部に設けたビット装着部２２ａがハウジング１３の胴部１４の先端から外部に露出している。ビット装着部２２ａには、図示略の種々の工具（ビット）が装着される。 A motor 20 is provided as a power source on the rear side of the body portion 14 of the housing 13. The motor 20 is drivingly connected to an output shaft 22 of the electric tool 10 via a torque amplifier 21 disposed on the front side of the body portion 14 of the housing 13, and a bit mounting portion 22 a provided at the distal end portion of the output shaft 22. Is exposed to the outside from the front end of the body portion 14 of the housing 13. Various tools (bits) (not shown) are mounted on the bit mounting portion 22a.
把持部１５の上端部の前側には、トリガスイッチ２３が設けられている。トリガスイッチ２３は、電動工具１０の駆動開始・停止を行う際に作業者の指による操作が可能に外部に露出して設けられるトリガレバー２４と、把持部１５内に配置されてトリガレバー２４の操作に応じた信号を生成するスイッチ回路２５とを備える。スイッチ回路２５は、トリガレバー２４のオンオフ操作信号やトリガレバー２４の操作量（引込量）に応じた信号を出力する。トリガスイッチ２３の近傍には、モータ２０の正逆回転を切り替える正逆切替スイッチ２６が設けられている。 A trigger switch 23 is provided on the front side of the upper end portion of the grip portion 15. The trigger switch 23 is disposed outside the trigger lever 24 so as to be exposed to the outside so that it can be operated by the operator's finger when starting and stopping the driving of the electric tool 10. And a switch circuit 25 that generates a signal corresponding to the operation. The switch circuit 25 outputs a signal corresponding to an on / off operation signal of the trigger lever 24 and an operation amount (retraction amount) of the trigger lever 24. In the vicinity of the trigger switch 23, a forward / reverse selector switch 26 for switching forward / reverse rotation of the motor 20 is provided.
図１及び図２に示すように、電池パック装着部１６の内部には、前後方向中央から前側にかけて回路保持部３０が構成されており、この回路保持部３０には制御回路４０が保持されている。制御回路４０、モータ２０、トリガスイッチ２３のスイッチ回路２５、正逆切替スイッチ２６、及び電池パック１２等は、各種のリード線２７や端子ユニット２８を用いることで電気的な接続が図られている。制御回路４０は、各種のスイッチ２３，２６の操作による電池パック１２から電動工具本体１１への電力供給に基づいてモータ２０の回転駆動を制御し、電動工具１０として機能させている。 As shown in FIGS. 1 and 2, a circuit holding unit 30 is configured from the center in the front-rear direction to the front side in the battery pack mounting unit 16, and the control circuit 40 is held in the circuit holding unit 30. Yes. The control circuit 40, the motor 20, the switch circuit 25 of the trigger switch 23, the forward / reverse selector switch 26, the battery pack 12 and the like are electrically connected by using various lead wires 27 and terminal units 28. . The control circuit 40 controls the rotational drive of the motor 20 based on the power supply from the battery pack 12 to the power tool main body 11 by the operation of various switches 23 and 26 to function as the power tool 10.
制御回路４０は、扁平な直方体状をなしている。制御回路４０は、例えば図５に示すように、上部全体が開口する樹脂製の基板ケース４１内に制御基板４２が収納され、この収納状態で制御基板４２の上面全体が封止材４３にて封止されて構成されている。制御基板４２には、その上面や下面に種々の電子部品が搭載されている。制御基板４２の下面に例えば背の高い電子部品４４が搭載されている本実施形態では、この電子部品４４を考慮して基板ケース４１の下面に膨出部４１ａが形成され、制御回路４０（基板ケース４１）が若干大型となっている。 The control circuit 40 has a flat rectangular parallelepiped shape. In the control circuit 40, for example, as shown in FIG. 5, the control board 42 is housed in a resin board case 41 whose upper part is open. It is configured to be sealed. Various electronic components are mounted on the upper and lower surfaces of the control board 42. In the present embodiment in which, for example, a tall electronic component 44 is mounted on the lower surface of the control board 42, a bulging portion 41a is formed on the lower surface of the substrate case 41 in consideration of the electronic component 44, and the control circuit 40 (board Case 41) is slightly larger.
一方、膨出部４１ａの分だけ制御回路４０（基板ケース４１）が大型化したのに対応して、図２〜図５に示すように、制御回路４０を収容する電池パック装着部１６の下面１６ａには開口窓１６ｂが設けられ、この開口窓１６ｂに制御回路４０の膨出部４１ａが挿入されている。 On the other hand, as shown in FIGS. 2 to 5, the lower surface of the battery pack mounting portion 16 that accommodates the control circuit 40, corresponding to the increase in the size of the control circuit 40 (substrate case 41) by the bulging portion 41 a. The opening window 16b is provided in 16a, and the bulging part 41a of the control circuit 40 is inserted in this opening window 16b.
つまり、電池パック装着部１６の下面１６ａは従来では壁により閉塞されるものが、その下面１６ａにおいては電池パック１２が装着されて閉塞（又は密閉）されるため、制御回路４０の一部を露出することが可能である。そのため、従来のように電池パック装着部１６の下面１６ａが壁により閉塞される構造では、制御回路４０の大型化は電池パック装着部１６の大型化に直結するが、制御回路４０の一部（膨出部４１ａ）を電池パック装着部１６の下面１６ａの開口窓１６ｂから突出させる本実施形態の構成では、電池パック装着部１６の大型化は抑えられる。 That is, the lower surface 16a of the battery pack mounting portion 16 is conventionally closed by a wall, but the battery pack 12 is mounted and closed (or sealed) on the lower surface 16a, so that a part of the control circuit 40 is exposed. Is possible. Therefore, in the conventional structure in which the lower surface 16a of the battery pack mounting portion 16 is closed by a wall, the increase in the size of the control circuit 40 is directly linked to the increase in the size of the battery pack mounting portion 16, but a part of the control circuit 40 ( In the configuration of the present embodiment in which the bulging portion 41a) is protruded from the opening window 16b on the lower surface 16a of the battery pack mounting portion 16, an increase in size of the battery pack mounting portion 16 is suppressed.
また、図３に示すように、制御回路４０の膨出部４１ａ及び電池パック装着部１６の下面１６ａの開口窓１６ｂはともに略矩形状をなしているが、膨出部４１ａの前側に凸部４１ｂが設けられ、これに対応して開口窓１６ｂの内周縁にも凹部１６ｃが設けられている。そのため、電池パック装着部１６に制御回路４０を組み込む際、この凸部４１ｂが凹部１６ｃに嵌合するように組み付けることで、制御回路４０が適正な向きでの組付状態となるように構成されている。 Further, as shown in FIG. 3, the bulging portion 41a of the control circuit 40 and the opening window 16b of the lower surface 16a of the battery pack mounting portion 16 are both substantially rectangular, but a convex portion on the front side of the bulging portion 41a. 41b is provided, and correspondingly, a recess 16c is also provided on the inner peripheral edge of the opening window 16b. Therefore, when the control circuit 40 is assembled in the battery pack mounting portion 16, the control circuit 40 is configured to be in an assembled state in an appropriate direction by assembling the convex portion 41b so as to fit into the concave portion 16c. ing.
また、図２（ａ）（ｂ）及び図４（ａ）（ｂ）に示すように、電池パック装着部１６内の回路保持部３０には、制御回路４０（基板ケース４１）の上面の側縁部と当接する複数の保持リブ３１が設けられている。保持リブ３１は、前後方向に複数個が互いに所定間隔を有して配置されている。保持リブ３１は、制御回路４０の上面の側縁部と当接して上面側を保持する。また、制御回路４０と保持リブ３１との当接箇所が小さい（少ない）ことから、制御回路４０の回路保持部３０への装着が容易であり、また電池パック装着部１６が変形する等の外力が作用しても、制御回路４０にその外力が伝達することが極力抑えられるようになっている。 Further, as shown in FIGS. 2A and 2B and FIGS. 4A and 4B, the circuit holding portion 30 in the battery pack mounting portion 16 has an upper surface side of the control circuit 40 (substrate case 41). A plurality of holding ribs 31 are provided in contact with the edge. A plurality of the holding ribs 31 are arranged at a predetermined interval in the front-rear direction. The holding rib 31 is in contact with the side edge portion of the upper surface of the control circuit 40 and holds the upper surface side. In addition, since the contact portion between the control circuit 40 and the holding rib 31 is small (small), it is easy to mount the control circuit 40 on the circuit holding unit 30 and the external force such as deformation of the battery pack mounting unit 16. Even if this works, the transmission of the external force to the control circuit 40 is suppressed as much as possible.
また、制御回路４０（基板ケース４１）の下面の膨出部４１ａの略中央部には、電池パック装着部１６に電池パック１２が装着された状態（図１参照）でその電池パック１２と電気的に接続するための接続コネクタ４５が備えられている。制御回路４０は、この接続コネクタ４５を通じて電池パック１２の電池電圧の測定等を行い、例えば電池パック装着部１６の上面に設けた表示窓１７を通じて電池パック１２に係る情報の表示等も行っている。 The battery pack 12 and the battery pack 12 are electrically connected to the battery pack mounting portion 16 (see FIG. 1) at a substantially central portion of the bulging portion 41a on the lower surface of the control circuit 40 (substrate case 41). A connection connector 45 is provided for connection. The control circuit 40 measures the battery voltage of the battery pack 12 through the connection connector 45, and displays information related to the battery pack 12 through the display window 17 provided on the upper surface of the battery pack mounting portion 16, for example. .
次に、本実施形態の効果を記載する。
（１）制御回路４０（基板ケース４１）の下面に膨出部４１ａが形成されて、内部に例えば背高の電子部品４４の搭載が可能である。一方で、電池パック装着部１６の下面１６ａは電池パック１２側に露出する部位（電池パック１２の装着時には外部に非露出となる部位）であるため、その下面１６ａに設けた開口窓１６ｂに制御回路４０の膨出部４１ａ部分が挿入されて組み込まれている。これにより、制御回路４０が例えば背高の電子部品４４を搭載することで大型化しても、電池パック装着部１６の大型化、つまり電動工具１０の大型化への影響を極力抑えることができ、電動工具１０の取り回しへの影響も小さい。なお、このことは、制御回路４０の実質の大型化のみならず、電池パック装着部１６の小型化による制御回路４０の相対的な大型化についても、同様の効果が期待できる。
Next, the effect of this embodiment will be described.
(1) A bulging portion 41a is formed on the lower surface of the control circuit 40 (substrate case 41), and for example, a tall electronic component 44 can be mounted therein. On the other hand, since the lower surface 16a of the battery pack mounting portion 16 is a portion exposed to the battery pack 12 side (a portion that is not exposed to the outside when the battery pack 12 is mounted), it is controlled by the opening window 16b provided on the lower surface 16a. The bulging portion 41a portion of the circuit 40 is inserted and incorporated. Thereby, even if the control circuit 40 is enlarged by mounting, for example, a tall electronic component 44, the influence on the enlargement of the battery pack mounting portion 16, that is, the enlargement of the electric power tool 10, can be suppressed as much as possible. The influence on the handling of the electric power tool 10 is also small. This can be expected not only to increase the size of the control circuit 40 substantially but also to increase the size of the control circuit 40 by reducing the size of the battery pack mounting portion 16.
（２）電池パック装着部１６の回路保持部３０には保持リブ３１が複数設けられ、制御回路４０の一部がリブ３１にて保持されている。これにより、制御回路４０の回路保持部３０への装着を容易とすることができる。また、電池パック装着部１６が変形する等の外力が作用しても、制御回路４０にその外力が伝達することを極力抑えることができる。 (2) The circuit holding part 30 of the battery pack mounting part 16 is provided with a plurality of holding ribs 31, and a part of the control circuit 40 is held by the ribs 31. Thereby, mounting | wearing to the circuit holding part 30 of the control circuit 40 can be made easy. Further, even when an external force such as deformation of the battery pack mounting portion 16 is applied, the transmission of the external force to the control circuit 40 can be suppressed as much as possible.
（３）制御回路４０の膨出部４１ａに凸部４１ｂ、電池パック装着部１６の開口窓１６ｂの内周縁に凹部１６ｃが設けられ、この凹凸嵌合にて回路保持部３０（電池パック装着部１６）に対する制御回路４０の装着向きを規制することができる。つまり、制御回路４０を常に適正向きで装着することができる。 (3) A bulging portion 41a of the control circuit 40 is provided with a convex portion 41b, and a concave portion 16c is provided on the inner peripheral edge of the opening window 16b of the battery pack mounting portion 16, and the circuit holding portion 30 (battery pack mounting portion) The mounting direction of the control circuit 40 with respect to 16) can be regulated. That is, the control circuit 40 can always be mounted in an appropriate direction.
なお、上記実施形態は、以下のように変更してもよい。
・制御回路４０の構成について、上記実施形態の構成（図５の構成）に限定されるものではなく適宜変更してもよい。例えば図６に示すように、制御回路４０の基板ケース４１の上部に蓋４１ｃを取り付ける等して閉塞する構造であってもよい。この場合、例えば蓋４１ｃの開口部４１ｄから制御基板４２のコネクタ４６を突出させ、リード線２７（図５参照）との接続を図るようにする。
In addition, you may change the said embodiment as follows.
The configuration of the control circuit 40 is not limited to the configuration of the above embodiment (configuration of FIG. 5), and may be changed as appropriate. For example, as shown in FIG. 6, a structure may be adopted in which a lid 41 c is attached to the upper part of the substrate case 41 of the control circuit 40 to close it. In this case, for example, the connector 46 of the control board 42 is projected from the opening 41d of the lid 41c so as to be connected to the lead wire 27 (see FIG. 5).
・図７に示すように、制御回路４０の膨出部４１ａと電池パック装着部１６の開口窓１６ｂの内周縁との間に所定量の間隙４７を設定してもよい。このようにすれば、制御回路４０の接続コネクタ４５と接続される電池パック１２とその接続コネクタ４５との間の位置ずれを許容することができる。また、使用時の振動等で電池パック１２と電動工具本体１１との間で相対的にずれても接続コネクタ４５（制御回路４０）は電池パック１２側に追従するため、接続コネクタ４５における接点摩耗を抑制することも期待できる。なお、接続コネクタ４５部分を制御回路４０の本体側に対してフロート支持してもよい。 As shown in FIG. 7, a predetermined amount of gap 47 may be set between the bulging portion 41 a of the control circuit 40 and the inner peripheral edge of the opening window 16 b of the battery pack mounting portion 16. In this way, it is possible to allow a positional shift between the battery pack 12 connected to the connection connector 45 of the control circuit 40 and the connection connector 45. Further, even if the battery pack 12 and the power tool body 11 are relatively displaced due to vibration during use, the connection connector 45 (control circuit 40) follows the battery pack 12 side. Can also be expected to be suppressed. The connecting connector 45 may be float supported with respect to the main body side of the control circuit 40.
・図８に示すように、上記した間隙４７に弾性部材４８を介装してもよい。このようにすれば、上記効果に加えて、制御回路４０の膨出部４１ａと電池パック装着部１６の開口窓１６ｂの内周縁との間で生じ得る衝突音の発生を抑制することができる。 As shown in FIG. 8, an elastic member 48 may be interposed in the gap 47 described above. In this way, in addition to the above effects, it is possible to suppress the occurrence of collision sound that may occur between the bulging portion 41a of the control circuit 40 and the inner peripheral edge of the opening window 16b of the battery pack mounting portion 16.
・図９に示すように、端子２８ａ及びこれを保持する樹脂製の保持部材２８ｂを有する端子ユニット２８のその保持部材２８ｂにて制御回路４０の一部を保持するようにしてもよい。つまり、端子ユニット２８と制御回路４０との間の壁を省略できる分、制御回路４０の大型化が可能である。 -As shown in FIG. 9, you may make it hold | maintain a part of control circuit 40 with the holding member 28b of the terminal unit 28 which has the terminal 28a and the resin-made holding member 28b holding this. That is, the size of the control circuit 40 can be increased by eliminating the wall between the terminal unit 28 and the control circuit 40.
・これらの他、電動工具１０の構成を適宜変更してもよい。
