That is, the connection terminals 30 and 31 electrically connect the battery pack 12 and the main body 11 to allow for the supply of power from the battery pack 12 to the main body 11.
  • connection terminals 30 and 31 are each formed by bending a metal plate.
  • flat middle portions 38 and 39 are located between the inner terminal portions 34 and 35 and the outer terminal portions 36 and 37, respectively.
  • Each of the outer terminal portions 36 and 37 is bent at a right angle at one side of the corresponding one of the middle portions 38 and 39 to extend downward.
  • the inner terminal portions 34 and 35 are bent in a diagonally upward direction so that the angle is acute between the inner terminal portions 34 and 35 and the middle portions 38 and 39.
  • bending lines L1a and L1b, at which the outer terminal portions 36 and 37 are bent are perpendicular to the bending lines L2a and L2b, at which the inner terminal portions 34 and 35 are bent, on a horizontal plane (plane of the middle portions 38 and 39).
  • connection terminals 30 and 31 When forming the connection terminal unit 29, the connection terminals 30 and 31 are arranged near each other so that the middle portions 38 and 39 of the connection terminals 30 and 31 are arranged on the same plane and the outer terminal portions 36 and 37 are parallel to each other.
  • the bending lines L1 a and L1b of the outer terminal portions 36 and 37 are arranged to be parallel, and the bending lines l2a and L2b of the inner terminal portions 34 and 35 are aligned with each other along the same line.
  • the middle portions 38 and 39 and the inner terminal portions 34 and 35 are located between the outer terminal portions 36 and 37. Molding is performed so that all of the middle portions 38 and 39, basal ends of the outer terminal portions 36 and 37, and basal ends of the inner terminal portions 34 and 35 are covered with plastic and integrated with one another. This forms the connection terminal unit 29.
  • the middle portions 38 and 39 of the connection terminals 30 and 31 lie along a transverse plane of the power tool 10 (main body 11), that is, a plane extending in the front-to-rear direction and the lateral direction (sideward direction).
  • the outer terminals 36 and 37 are arranged extending downward from the middle portions 38 and 39 so that the outer terminal portions 36 and 37 lie along a sagittal plane of the power tool 10 (main body 11), that is, a plane extending in the front-to-rear direction and the vertical direction.
  • the bending lines L2a and L2b of the inner terminal portions 34 and 35 extend in the lateral direction (sideward direction).
  • the inner terminal portions 34 and 35 extend in a diagonally upward direction and are slightly sloped toward the front from the rear ends of the middle portions 38 and 39.
  • the grip 15 has a small (narrow) profile so that the user can hold the grip 15 with a single hand.
  • the battery pack 12 has a profile that is much larger than the battery pack 12 so that the power tool 10 may be operated as long as possible.
  • the battery pack mount 16 is shaped to become smaller in size from the lower end, which is attached to the large battery pack 12, toward the small grip 15.
  • connection terminal unit 29 is incorporate in the rear side of the battery pack mount 16, the shape of which is gradually reduced in size from the battery pack mount 16 to the grip 15.
  • the battery pack mount 16 has a rear wall 40 that is inclined toward the front side.
  • the inner terminal portions 34 and 35 are bent in the diagonally upward direction to extend as close as possible along the sloped form of the rear wall. This allows for the connection terminal unit 29 to be arranged at the rearmost portion of the battery pack mount 16 and allows for the connection terminal unit 29 to be shaped and arranged in an efficient manner without forming unnecessary space around the inner terminal portions 34 and 35.
  • a new tool may be designed based on the present power tool 10 when, for example, slightly changing the outer shape of the grip 15 or the battery pack mount 16 or slightly changing the shape of an internal component such as the control circuit 27.
  • restrictions are imposed on the location of the connection terminal unit 29 in the battery pack mount 16 due to the rear wall 40 of the battery pack mount 16.
  • the connection terminal unit 29 may easily cope with changes in the shape of the grip 15 or the battery pack mount 16 by changing the inclined amount (bent amount) of the inner terminal portions 34 and 35 in the front-to-rear direction and the vertical direction.
  • a comparative example uses connection terminals 30 and 31 that are bent in the usual crank-shaped manner.
  • the bending lines L2a and L2b of the inner terminal portions 34 and 35 are set to be parallel to the bending lines L1a and L1b of the outer terminal portions 36 and 37.
  • the inner terminal portions 34 and 35 are bent upward at a right angle at sides of the middle portions 38 and 39 opposite to the outer terminal portions 36 and 37 so that the outer terminals portions 36 and 37 are parallel to the inner terminal portions 34 and 35.
  • the inner terminal portions 34 and 35 of the connection terminals 30 and 31 are projected upward over a long amount.
  • the inner terminal portions 34 and 35 easily interfere with the rear wall 40 or the like of the battery pack mount 16 when adjusting the location of the connection terminal unit 29. Consequently, in the connection terminals 30 and 31 of the comparative example, the degree of layout freedom is low in the front-to-rear direction and the vertical direction, and the degree of design freedom is low for the shape of the grip 15 and the surrounding portions.
  • connection terminal unit 29 has a high degree of layout freedom.
  • the degree of design freedom is high for the grip 15 and the surrounding portions.
  • the present embodiment has the advantages described below.
  • the bending lines L2a and L2b of the inner terminal portions 34 and 35 do not have to extend in the sideward direction (lateral direction). Further, the inner terminal portions 34 and 35 do not have to be bent at an acute angle.
  • the inner terminal portions 34 and 35 may be bent upward at a right angle.
  • the bent lines L2a and L2b of the inner terminal portions 34 and 35 may be set to be parallel to the bending lines L1a and L1b of the outer terminals 36 and 37.
  • the inner terminal portions 34 and 35 are bent at obtuse angles so that the distal ends extend toward each other. This allows the grip 15 to be reduced in size.
  • the inner terminal portions 34 and 35 may be bent to be non-parallel to the outer terminal portions 36 and 37, and the inner terminal portions 34 and 35 and the outer terminal portions 36 and 37 (sagittal plane) may face different directions. This would also obtain the advantages described below.
  • connection terminals 30 and 31 are bent at the same angle. Instead, the connection terminals 30 and 31 may be bent at different angles.
  • the inner terminal portion 34 of the connection terminal 30 does not have to be branched into two sections.
  • branched sections may be omitted from the inner terminal portion 34.
  • the inner terminal portion 34 may include three or more branched sections. Further, each branched section may be bent at a different bending angle.
  • the power tool 10 may be a hand-held power tool other than a drill driver.
  • the power tool 10 may be an impact driver, an impact wrench, a hammer drill, a jigsaw, a sealing gun, or the like.
  • the distal ends of the inner terminal portions 34 and 35 may be located in the battery pack mount 16, in the grip 15, or in the bordering portion between the battery pack mount 16 and the grip 15.
