The waterproof wall 18 is arranged so as to block between the opening 38 and the control board 16. The lower end of the waterproof wall 18 is arranged below the control board 16. The waterproof wall 20 extends in the sliding direction along the right edge of the opening 40. The waterproof wall 20 is arranged so as to block between the opening 40 and the control board 16. The lower end of the waterproof wall 20 is arranged below the control board 16. In the left-right direction, the control board 16 is arranged between the waterproof walls 18 and 20. When water enters the inside of the housing 12 through the openings 38 and 40, respectively, the waterproof walls 18 and 20 guide the invading water downward.

As shown in FIG. 7, pins 32a and 32b extend downward on the upper inner surface of the upper housing 28. In the left-right direction, the pin 32a is located between the waterproof wall 18 and the right edge of the opening 38. In the left-right direction, the width W1 between the pin 32a and the waterproof wall 18 is substantially the same as the width W2 between the pin 32a and the right edge of the opening 38. Further, in the left-right direction, the pin 32b is arranged between the waterproof wall 20 and the left edge portion of the opening 40. In the left-right direction, the width W1 between the pin 32b and the waterproof wall 20 is substantially the same as the width W2 between the pin 32b and the left edge of the opening 40.

Therefore, it is possible to prevent the urging spring 26b from interfering with the waterproof wall 20 and deteriorating the attachability of the urging spring 26b.

As shown in FIG. 8, the lower housing 30 is formed with rails 50 and 52 and a terminal mounting portion 54. The rails 50 and 52 have a longitudinal direction in the front-rear direction. The rail 50 is arranged at the right end of the lower surface 30a of the lower housing 30 which is arranged on the opposite side of the upper surface 28a of the upper housing 28. The rail 52 is arranged at the left end of the lower surface 30a of the lower housing 30. The rails 50 and 52 are longer than the rails (not shown) of the battery-side mounting portion 4a of the battery 4. As a result, the adapter 2 cannot be erroneously attached to an electric device other than the battery checker 6, such as an electric tool or an electric work machine. Further, the rail 52 extends longer toward the front side than the front end portion of the rail 50. As a result, the adapter 2 can be attached to and detached from the old battery checker 6, but cannot be attached to and detached from the new battery checker 6. When the checker-side mounting portion 6a of the battery checker 6 is mounted on the checker-mounting portion 8 of the adapter 2, the rails 50 and 52 guide the checker-side mounting portion 6a in the slide direction. The terminal mounting portion 54 is arranged between the rails 50 and 52.

Further, the adapter 2 further includes a hook 130. The hook 130 is arranged at the rear end of the adapter 2. By being urged by the urging spring 132 (see FIG. 9), the hook 130 normally projects downward from the lower surface 30a of the lower housing 30. The hook 130 has a longitudinal direction in the vertical direction. The adapter 2 is held by the battery checker 6 by engaging the hook 130 with an engagement groove (not shown) formed on the upper surface of the battery checker 6.

As shown in FIG. 6, the adapter 2 further includes inner walls 22 and 24. The inner walls 22 and 24 are housed inside the upper housing 28 and the lower housing 30. The inner walls 22 and 24 extend upward from the lower inner surface of the lower housing 30. The inner walls 22 and 24 have a longitudinal direction in the front-rear direction. The inner wall 22 is located on the left side of the waterproof wall 18 and on the right side of the control board 16. Further, the upper end portion of the inner wall 22 is arranged above the lower end portion of the waterproof wall 18 and the control board 16. The inner wall 24 is located on the right side of the waterproof wall 20 and on the left side of the control board 16. Further, the upper end portion of the inner wall 24 is arranged above the lower end portion of the waterproof wall 20 and the control board 16. In the left-right direction, the control board 16 is arranged between the inner walls 22 and 24. Further, in the left-right direction, the inner walls 22 and 24 are arranged between the waterproof walls 18 and 20. In the left-right direction, the inner wall 22 overlaps the waterproof wall 18, and the inner wall 24 overlaps the waterproof wall 20, so that the inner walls 22 and 24 and the waterproof walls 18 and 20 form a labyrinth structure. As a result, water that has entered the inside of the housing 12 through the openings 38 and 40 is controlled as compared with the case where the adapter 2 includes only one of the waterproof walls 18 and 20 and the inner walls 22 and 24. It is possible to further suppress reaching the substrate 16.

Step portions 58 and 60 are formed on the inner surface of the lower housing 30. The step portion 58 is arranged on the right side of the inner wall 22 and the waterproof wall 18. The lower inner surface of the lower housing 30 on the right side of the step portion 58 is located above the lower inner surface between the step portion 58 and the inner wall 22. A waterproof groove 64 is formed between the step portion 58 and the inner wall 22. The step portion 60 is arranged on the left side of the inner wall 24 and the waterproof wall 20. The lower inner surface of the lower housing 30 on the left side of the step portion 60 is located above the lower inner surface between the step portion 60 and the inner wall 24. A waterproof groove 66 is formed between the step portion 60 and the inner wall 24. A waterproof groove 66 is formed. The waterproof grooves 64 and 66 have a longitudinal direction in the front-rear direction. The lower end of the waterproof wall 18 is arranged in the waterproof groove 64. Further, the lower end portion of the waterproof wall 20 is arranged in the waterproof groove 66. The waterproof grooves 64 and 66 receive the water guided by the waterproof walls 18 and 20, respectively.

Discharge ports 68 and 70 are formed in the lower housing 30. The discharge port 68 is arranged at the front end of the waterproof groove 64. Further, the discharge port 70 is arranged at the front end portion of the waterproof groove 66.

When the adapter 2 is attached to the battery checker 6 mounted on the horizontal plane, the lower surface 30a of the lower housing 30 is inclined from the upper side to the lower side from the rear side to the front side with respect to the horizontal plane. .. Therefore, the waterproof grooves 64 and 66 are inclined from the upper side to the lower side from the rear side to the front side with respect to the horizontal plane. As a result, the water dropped from the waterproof walls 18 and 20 into the waterproof grooves 64 and 66 flows toward the front side and is discharged from the discharge ports 68 and 70 to the outside of the housing 12. The water discharged from the discharge ports 68 and 70 travels along the outer surface of the battery checker 6 and drops below the battery checker 6.

Further, even when the adapter 2 is placed on a horizontal plane, the lower surface 30a of the lower housing 30 is inclined from the upper side to the lower side from the rear side to the front side with respect to the horizontal plane. Therefore, the waterproof grooves 64 and 66 are inclined from the upper side to the lower side from the rear side to the front side with respect to the horizontal plane. As a result, the water that has moved from the waterproof walls 18 and 20 to the waterproof grooves 64 and 66 flows toward the front side and is discharged from the discharge ports 68 and 70 to the outside of the housing 12.

As described above, the adapter 2 includes a control board 16. As shown in FIG. 9, the control board 16 is arranged parallel to the lower surface 30a of the lower housing 30. The control board 16 is inclined with respect to the upper surface 28a of the upper housing 28. In this embodiment, the upper surface 28a of the upper housing 28 is inclined at an angle of 5 ° with respect to the lower surface 30a of the lower housing 30. The upper surface 28a of the upper housing 28 may be inclined at an angle larger than 0 ° and 10 ° or less with respect to the lower surface 30a of the lower housing 30, and is larger than 0 ° and 15 ° or less. It may be tilted at an angle of.

A device-side terminal 74 is mounted on the lower surface 16a of the control board 16.

The front surface 94 is orthogonal to the upper surface 16b of the control board 16 and is inclined with respect to the direction orthogonal to the upper surface 28a of the upper housing 28. The rear surface 96 is orthogonal to the upper surface 28a of the upper housing 28 and is inclined with respect to the direction orthogonal to the upper surface 16b of the control board 16. The rear surface 96 is orthogonal to the slide direction in which the battery 4 is slid with respect to the adapter 2. The tip surface 98 is a surface arranged farthest from the upper surface 28a of the upper housing 28. The tip surface 98 is parallel to the upper surface 28a of the upper housing 28 and is inclined with respect to the direction orthogonal to the upper surface 16b of the control board 16. The tip surface 98 is parallel to the slide direction in which the battery 4 is slid with respect to the adapter 2.

The height from the upper surface 28a of the upper housing 28 to the tip surface 98 of the first battery side terminal 78 is the same as the height from the upper surface 28a of the upper housing 28 to the tip surface 112 of the second battery side terminal 80. The upper surface 28a of the upper housing 28 is inclined with respect to the upper surface 16b of the control board 16, and approaches the upper surface 16b of the control board 16 toward the front side. Therefore, the root portion 102 of the second battery side terminal 80 is inserted into the mounting hole 92 of the control board 16 deeper than the root portion 86 of the first battery side terminal 78. The height from the upper surface 28a of the upper housing 28 to the tip surface 124 of the third battery side terminal 82 is higher than the height from the upper surface 28a of the upper housing 28 to the tip surface 98 of the first battery side terminal 78 by a predetermined amount. The predetermined amount is, for example, 1 mm or less. Since the predetermined amount is set to 1 mm or less, when the battery 4 is attached to the adapter 2, it is possible to prevent the battery 4 from being caught in the third battery side terminal 82. Further, when the height from the upper surface 28a of the upper housing 28 to the tip surface 124 of the third battery side terminal 82 is the same as the height from the upper surface 28a of the upper housing 28 to the tip surface 98 of the first battery side terminal 78. The amount of protrusion of the base portion 114 of the third battery-side terminal 82 downward from the lower surface 16a of the control board 16 can be reduced as compared with the above. As a result, the adapter 2 can be miniaturized in the vertical direction.

Next, a method of mounting the battery-side terminal 76 on the upper surface 16b of the control board 16 will be described. First, by insert molding, six battery-side terminals 76 are integrally molded with the upper housing 28. Next, two diagonal corners of the four corners of the control board 16 are inserted into the positioning pins 44 of the upper housing 28. As a result, the control board 16 is positioned with respect to the upper housing 28, and the root portions of the six battery-side terminals 76 are inserted into the mounting holes 92 of the control board 16 and are lowered from the lower surface 16a of the control board 16.
