Stranded wire retaining channel for an electrical tool
An electrical tool includes a housing, a conductor channel, and a stranded conductor. The housing includes a motor, electronics, and drive gear. The conductor channel has a flexible section and a rigid section. The stranded conductor is in a receptacle of the conductor channel. One end of the stranded conductor is connected to a conductor of a network cable of the electrical tool. Another end of the stranded conductor is conductively connected with a component of the electrical tool.
