FIELD: process engineering.SUBSTANCE: invention relates to electrically driven tools. Proposed tool comprises motor housing 105, motor 121, terminal 163 on motor side, unit of switches 153 and terminal 159 on switch side for connection to terminal 163 on motor side. Hollow tubular element 165 is arranged on motor housing or that of unit of switches to extend along motor housing 105 while connector 169 is arranged on other housing of motor or unit of switches and fitted in said tubular element 165. Terminal on motor side and switch side are interconnected inside said tubular element. Unless said terminals are interconnected, tubular element 165 and connector 169 are retained to isolate connected between terminals isolated from outer side of tubular element 165.EFFECT: dustproof connection of terminals.5 cl, 8 dwg |
