成している。The present invention will be described in more detail below based on embodiments shown in the accompanying drawings. FIG. 1 is a top view of a plastic terminal box according to the present invention, and FIG. 2 is a sectional view taken along arrow line -H in FIG. Referring to both figures, at the bottom of the box body 10 of the terminal box, there is a terminal block 16 that electrically connects the internal wiring cable of the main motor 36 and the external wiring cable, and a terminal block 16 that is attached to the rear end of the main motor 36. Another terminal block 2 electrically connects the internal wiring cable pulled out from the fan housing 38 that accommodates and holds the fan that cools the main motor and the motor for driving the fan and the external wiring cable.
4 are integrally injection molded. The material of this terminal box is, for example, a heat-resistant and oil-resistant engineering plastic material such as polybutylene terephthalate, and its material strength is inferior to that of metal. Therefore, a lattice-like lip 14 is provided at the bottom of the box body 10, and flanges 12 are formed around the sides.

体１０の補強リブとして作用している。In addition to providing the lip 14 and flange 12 for reinforcing purposes as described above, in the present invention, the terminal blocks 16 and 24 are also provided on the box body 10.
By molding it integrally with the terminal box, the structural strength of the terminal box is further increased. That is, the main bodies 18 and 4 of the terminal blocks 16 and 24
4 also serves as a reinforcing material for the box body 10, and furthermore, the insulating plates 20 and 26 between each phase wiring of each terminal block 16 and 24 also act as reinforcing ribs for the box body 10.
