いる。The terminal cover 5 is formed in a cylindrical shape with its upper part closed, and a lead wire 12 extending from the sealed terminal 7 and the overload relay 8.
A take-out part 11 for taking out the outside of the take-out part, and a plurality of projections 14 are provided at the upper edge of the opening part of the take-out part 11.
Is provided. Also, the gasket 4
Corresponds to the projecting direction of the take-out portion 11, and the take-out portion 1
A protruding piece 13 that is slightly larger than 1 is formed.

れる。However, in the protective structure for electrical components disclosed in the above publication, when the lead wire is sandwiched by the protrusion of the lead-out portion and the protruding piece of the gasket, the coating covering the surface of the lead wire is broken. Therefore, when a plurality of lead wires are taken out from the extraction portion, it is feared that the lead wires are short-circuited with each other and the compressor malfunctions.

The lead wire must be held so that the lead wire can be reliably positioned in the extraction section, and also check if the lead wire is not sandwiched between the terminal cover and the gasket in a place other than the extraction section. Because I need
There is a problem that the work of assembling the terminal cover is complicated.

なっている。Further, in the protective structure for electrical components disclosed in the above-mentioned publication, as described above, the purpose is to prevent water from entering the terminal cover through the take-out portion. It is extremely difficult to completely eliminate the gap between the wire and the take-out part and the protruding part of the gasket, and the gasket is flat from the part that is closer than the take-out part of the protruding part to the part inside the terminal cover. ing.

っている（請求項１）。SUMMARY OF THE INVENTION In the structure for covering the exposed electrical components of a compressor according to the present invention, however, a base is provided on the upper surface of a hermetically sealed container of the compressor, and the base is provided inside the hermetically sealed container of the compressor. In an exposed electric component covering structure of a compressor, in which an electric component for connecting an electric element through a lead wire is arranged, and a protective cover is attached to the airtight container so as to cover the electric component by assembling the electric component, a peripheral edge of the base. A side wall and a notch formed in a part of the side wall, and the protective cover has a bulging portion protruding outward with respect to the side wall of the base body according to the direction of the notch of the side wall. Is provided, and an opening is formed on the protruding side surface of the bulging portion (claim 1).

A structure in which a step is formed so as to abut is desired (claim 2). Further, the exposed electric component cover structure of the compressor is desired to have a structure in which a predetermined gap is formed between the lower end portion of the protective cover and the upper surface of the closed container when the protective cover is assembled to the base body ( Claim 3).

A bulging portion 18 is provided by protruding a lower portion of the cylindrical portion 16a from the step portion 17 in the lateral direction of the protective cover 16. The shape of the bulging portion 18 is not particularly limited, but in this embodiment, the protruding side surface 18a has a flat plate shape extending parallel to the longitudinal direction of the protective cover 16. The lead wires 12, 1 described above are attached to the protruding side surface 18a.
An opening 19 for taking out 4 is formed, and the width of the opening 19 in the longitudinal direction of the protective cover 16 is somewhat smaller than that of the protruding side surface 18a.

The size can be reduced, and the protective cover 16 can be easily held when the protective cover 16 is attached or detached. Further, since the strength of the protective cover 16 can be increased without mixing the glass fiber with the material, the material cost can be reduced. Furthermore, since glass fiber is not required as a material, the material is evenly distributed over the mold when the protective cover 16 is molded, which makes it easier to maintain the shape accuracy of the protective cover 16 and accordingly extends the mold life. .

First, the lead wires 12 and 14 are taken out from the cutouts 8 of the substrate 5, and then the protective cover 16 is assembled to the substrate 5 as shown in FIG. Done by. Then, as shown in FIG. 5, the assembly is carried out by pressing the end of the lever 26 with a finger to lift the locking claw 28, and then the protective cover 16 is attached to the base body 5.
And the locking claw 23 of the cutout piece 22 is fitted into the fitting hole 15 of the base 5, and the finger is released to fit the locking claw 28 of the lever 26 into the fitting hole 15 of the base 5. It is carried out by

Since the pedestal 3 and the base 5 on which the terminal 10 and the temperature sensor 11 are arranged have a step due to the side wall 7 or a step due to the pedestal 6 at the cutout 8, the opening 19 is used as an example.
Even if water enters from the inside, it is blocked by the step between the pedestal portion 3 and the side wall 7 or the pedestal 6 and does not enter the inside of the base body 5.
