- the rear end of the handle 212 is gradually reducing in diameter and smoothly arched, configuring an insertion portion 213.
- the insertion portion 213 has an opening 214 at the bottom side.
- a trigger 215 is mounted on the handle 212 for starting the electrical tool 20.
- the power drive 22 is mounted inside the body 211 of the housing 21, comprising a motor 221 and a transmission gear set 223.
- the tool-holding member 23 is mounted in one side of the body 211 of the housing 21 remote from the handle 212, having a coupler 232 extending out of the body 211 for holding a tool, such as drill bit, screwdriver bit, etc.
- the tool-holding member 23 is coupled to the transmission gear set 223 and rotatable by the motor 221.
- the battery 24 is mounted inside the handle 212 of the housing 21 and electrically connected to the motor 221 to provide the motor 221 with the necessary working power.
- the charging terminal 25 is mounted in the insertion portion 213 of the housing 21, having an electrically insulative base 251, a first contact 252, and a second contact 253.
- the base 251 has an insertion hole 254 aimed at the opening 214 at the insertion portion 213.
- the first contact 252 is a cylindrical metal contact coaxially suspending in the insertion hole 254.
- the second contact 253 is mounted on the peripheral wall of the insertion hole 254 and spaced around the first contact 252.
- the first contact 252 and the second contact 253 are respectively electrically coupled to the positive and negative terminals of the battery 24.
- the charger 30 comprises a deck 32, a charging circuit board 34, and a charging terminal 36.
- the deck 32 has a top cover shell 321 and a bottom cover shell 322.
- the top cover shell 321 has a recessed seat 323 and a receptacle 324 disposed at the top at different elevations, a locating groove 325 abutted to one side of the recessed seat 323.
- the receptacle 324 is configured to fit the contour of the smoothly arched and gradually reducing insertion portion 213 of the electrical tool 20 so that the insertion portion 213 of the electrical tool 20 can only be inserted into or moved out of the receptacle 324 in a particular direction.
- the insertion portion 213 After insertion of the insertion portion 213 into the receptacle 324, the insertion portion 213 is kept in the receptacle 324 firmly in position. At this time, the body 211 of the electrical tool 20 is partially positioned on the recessed seat 323, and the trigger 215 of the handle 212 is positioned in the locating groove 325. Further, the deck 32 defines an accommodation chamber 326.
- the receptacle 324 has a bottom through hole 327 in communication with the accommodation chamber 326.
- the top cover shell 321 has a retaining groove 329 disposed inside the accommodation chamber 326 near the bottom.
- the bottom cover shell 322 has a hooked portion 328 for engaging the retaining groove 329 to secure the top cover shell 321 and the bottom cover shell 322 together.
- the central axis of the insertion hole 254 of the charging terminal 25 of the electrical tool 20 is in parallel to the insertion direction in which the insertion portion 213 is inserted into or moved away from the receptacle 324.
- the charging circuit board 34 is mounted on the bottom cover shell 322 inside the deck 32, having a charging circuit and a power jack 342.
- the power jack 342 is adapted to receive one end of a power cord, which has an electric plug at the other end for connection to an electric outlet to provide the charging circuit board 34 with the necessary charging power for charging the battery 24 of the electrical tool 20.
- the charging terminal 36 of the charger 30 comprises an electrically insulative tubular base 362, a first contact 364, and a second contact 366.
- the tubular base 362 is fixedly mounted on the charging circuit board 34 and inserted through the bottom through hole 327 into the receptacle 324.
- the central axis of the tubular base 362 is kept in parallel to the insertion direction in which the insertion portion 213 is inserted into or moved away from the receptacle 324.
- the first contact 364 is mounted on the inside wall of the tubular base 362.
- the second contact 366 is mounted on the outside wall of the tubular base 362. Further, the first contact 364 and the second contact 366 are respectively electrically coupled to the positive and negative poles of the charging circuit of the charging circuit board 34.
- the tubular base 362 of the charging terminal 36 of the charger 30 is inserted through the opening 214 of the insertion portion 213 into the insertion hole 254 of the charging terminal 25 of the electrical tool 20, and the first contact 252 of the charging terminal 25 of the electrical tool 20 is inserted into the tubular base 362 of the charging terminal 36 of the charger 30, and therefore the first contact 252 and second contact 253 of the charging terminal 25 of the electrical tool 20 are respectively electrically connected to the first contact 364 and second contact 366 of the charging terminal 36 of the charger 30.
- the contour of the insertion portion 213 matches the configuration of the receptacle 324 and because the central axis of the insertion hole 254 of the charging terminal 25 of the electrical tool 20 and the central axis of the tubular base 362 of the charging terminal 36 of the charger 30 are in parallel to the insertion direction in which the insertion portion 213 is inserted into or moved away from the receptacle 324, the electrical tool 20 can positively and accurately be inserted into the charger 30, keeping the charging terminal 25 of the electrical tool 20 and the charging terminal 36 electrically connected.
- the electrical tool 20 when the electrical tool 20 is inserted into the charger 30, a part of the body 211 and the trigger 215 of the electrical tool 20 are respectively positioned in the recessed seat 323 and the locating groove 325, and therefore the electrical tool 20 is prohibited from displacement relative to the charger 30.
- the electrical tool assembly 10 when the electrical tool assembly 10 is charging the battery, the electrical tool 20 is kept positively inserted in the charger 30.
