A brush block assembly of a propeller deicing system, comprising:
- two or more brushes arranged in one or more rows, each of the two or more brushes comprised of a pressed electrically conductive material with an integral lead wire and a terminal;
- one or more terminal studs, each of the two or more brushes within a same one of the one or more rows being separated from an adjacent one of the two or more brushes by one of the one or more terminal studs;
- a helical spring coupled respectively to each of the two or more brushes;
- and
- insulated wires from a power supply and the respective terminal of each of the two or more brushes within the same one of the one or more rows being retained by the one of the one or more terminal studs in the one of the one or more rows, wherein the insulated wires couple to the terminal of a respective one of the two or more brushes at a side opposite a side adjacent to the adjacent one of the two or more brushes.
A method of assembling a brush block assembly of a propeller deicing system, the method comprising:
- disposing an insert with two or more brush pockets to house respective two or more brushes, each of the two or more brushes including a pressed electrically conductive material with an integral lead wire and a terminal;
- coupling each of the two or more brushes with a respective helical spring;
- disposing one or more terminal studs between adjacent ones of the two or more brushes;
- and
- routing insulated wires from the respective terminal of each of the two or more brushes to the one or more terminal studs such that the insulated wires couple to the terminal of a respective one of the two or more brushes at a side opposite a side adjacent to the adjacent one of the two or more brushes, the insulated wires supplying power to the two or more brushes.
