Abstract: An insertion slot connector and a connector assembly. The insertion slot connector includes an insulating body and multiple conductive terminals. The insulating body includes two side walls, a bottom wall and an insertion slot. The insulating body has a mating surface and a mounting surface provided opposite to each other. The insertion slot runs through the mating surface. Each conductive terminal includes a base, an elastic arm extending from the base toward the mating surface and turns back to extend toward the bottom wall, a contact portion provided at a tail end of the elastic arm and a soldering portion. A distance between the insertion slot and the soldering surface of the soldering portion in the insertion direction is not greater than 0.70 mm. The connector assembly includes a circuit board and at least one insertion slot connector and at least one card edge connector alternately mounted thereon.

Abstract: A vacuum cleaner has a brush roll which has a housing. A motor is disposed within the housing and has a pulley mounted on a shaft of the motor. A roller is disposed within the housing and has a drive wheel. A belt couples the pulley to the drive wheel, so that the motor can drive the roller. The roller has bristles for sweeping a surface to be cleaned.

Abstract: A small size permanent magnet direct current motor has a housing accommodating a permanent magnet stator and a wound rotor. The rotor has a rotor core with a diameter of 23 mm±3 mm and 12 poles and a cylindrical commutator. The motor has an output power of more than 25 watts.
