Claims

[Scope of Claim for Utility Model Registration] 1. In the internal power wiring of a power tool, a so-called wiring block in which conductors for electrically connecting parts such as switches and carbon brushes are held in a rigid insulator, and the wiring block A wiring board on which a power supply terminal portion and a switch are mounted to form a wiring circuit, a so-called power supply wiring block, is characterized in that a power receiving terminal of the wiring block and a power supply terminal of the power supply wiring block are in contact with each other on the same plane. Internal wiring device for power tools. 2. Claim 1, characterized in that the vicinity of the power supply terminal portion of the power supply wiring block is fixed to the case with screws.
Internal wiring device of the power tool described. 3. The internal wiring device for a power tool according to claim 1, wherein an end of the power receiving terminal of the wiring block forms a curved beam. 4. The internal wiring device for a power tool according to claim 1, wherein the case housing the power receiving terminal of the wiring block is not integrally molded with the wiring block main body, but is combined to form the wiring block. 5. The internal wiring device for a power tool according to claim 4, wherein the wiring block body is provided with a hole that engages with a case housing a power receiving terminal. 6. The interior of the power tool according to claim 4, wherein one of the conductors provided in the wiring block body and at least a portion of one of the conductors of the power receiving terminal are electrically connected inside the hole. Wiring device. 7. The internal wiring device for a power tool according to claim 4, characterized by an abutment surface that inevitably determines the insertion position when a case for storing a power receiving terminal is inserted into the hole formed in the wiring block main body.
