Terminal block assembly, substrate and method of manufacture thereof

A method of manufacture of a power tool comprising:

• connecting at least one wire to at least one second electrical connector on a substrate;
• covering the at least one second electrical connector and at least a portion of the at least one wire with an overmold;
• mounting the substrate on at least one terminal of a terminal block, the substrate having at least one first electrical connector in electrical connection with the at least one second electrical connector;
• connecting the at least one terminal to the at least one first electrical connector;
• and
• mounting the terminal block and substrate on a housing of the power tool.

A terminal block assembly for a power tool comprising:

• a terminal block having at least one primary terminal configured for electrical connection with a battery and at least one secondary terminal in electrical connection with the at least one primary terminal;
• a substrate mounted on the terminal block, the substrate having at least one first electrical connector electrically connectable with the at least one secondary terminal and at least one second electrical connector in electrical connection with the at least one first electrical connector;
• at least one wire electrically connected to the at least one second electrical connector;
• and
• a curable material configured to cover the at least one second electrical connector and at least a portion of the at least one wire.
