Is a compressor body, 2 is a bracket having a substantially U-shape fixed to the outer surface of the compressor body 1, 3 is a locking hole provided on two opposite sides of the bracket 3, and 4 is an end portion of the bracket 3. ,
Reference numeral 5 is an electrical component cover for protecting electrical components, 6 is a claw portion that is tapered in the insertion direction at a position corresponding to the locking hole 3 of the bracket 2 provided on the two inner facing surfaces, and 7 is an end portion of the bracket 2. 4 is a locking rib corresponding to 4, 8 is a notch provided in the locking rib 7, and 9 is a glass terminal.

In the above structure, the compressor body 1
Locking holes 3 provided on two opposing sides of the bracket 2 while the electrical component cover is fitted onto the bracket 2 fixed to the outer surface of the bracket 2.
The inside of the electrical component cover 5 corresponding to the end 4 of the bracket 2 is engaged with the tapered claw portion 6 provided in the insertion direction at the position corresponding to the locking hole 3 of the electrical component cover 5. It is fixed by coming into contact with the locking rib 7 having the cutout portion 8 provided in the.

[0006]

However, in the above structure, the mold for the electrical component cover is complicated and expensive.

In view of the above-mentioned problems, the present invention provides an electric component cover fixing device for a compressor which simplifies the mold structure of the electric component cover and reduces the cost while maintaining the same workability as the conventional one. is there.

[0008]

In order to solve the above problems, an electric component cover fixing device for a compressor according to the present invention includes a bracket fixed to surround a glass terminal provided in the compressor, and an electric component. And an electric component cover for covering the electric component cover. The bracket has a substantially square shape and has tapered cut-and-raised portions on two opposite sides, and the electric component cover has a tapered shape provided on the bracket on two opposing surfaces. There is a locking hole at a position corresponding to the cut-and-raised part, and when the electrical component cover is inserted into the bracket, the taper-shaped cut-and-raised part engages with the locking hole, and the cut part of the bracket The structure is fixed by being brought into contact with the end portion.

[0009]

With the above-described structure, the present invention corresponds to the tapered cut-and-raised portions provided on the two opposing sides of the bracket and the tapered cut-and-raised portions provided on the bracket on the two opposing surfaces of the electrical component cover. Even if the electrical component cover is pulled after being locked by the locking hole at the corresponding position, the locking hole and the tapered cut-and-raised portion are locked, so that the fixing is simple and reliable.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An electric component cover fixing device for a compressor according to an embodiment of the present invention will be described below with reference to the drawings.

FIG. 1 is an exploded perspective view showing a fixing device for an electric component cover according to an embodiment of the present invention, FIG. 2 is an enlarged plan view showing a mounting state of the fixing device for an electric component cover of the present invention, and FIG. It is an assembly enlarged side view which shows the fixing device of an electrical equipment cover.

Reference numeral 11 is a compressor body, 12 is a bracket having a substantially square shape fixed to the outer surface of the compressor body 11, and 13 is a bracket.
Is a taper-shaped cut-and-raised portion provided on two opposite sides of the bracket 12, 14 is an end of the bracket 12, 15 is an electrical component cover for protecting electrical components, and 16 is two opposing faces of the electrical component cover 15. Locking holes provided at positions corresponding to the tapered cut-and-raised portions 13 provided on the bracket 12.
Is a locking rib corresponding to the end 14 of the bracket 12,
Reference numeral 18 is a notch provided in the locking rib 17, and 19 is a glass terminal.

The attachment of the electrical component cover 15 of the compressor electrical component cover fixing device configured as described above will be described below with reference to FIGS. 1 to 3.

First, while the electrical component cover 15 is fitted onto the bracket 12 fixed to the outer surface of the main body 11 of the compressor, the electrical component is attached to the tapered cut-and-raised portions 13 provided on the two opposite sides of the bracket 12. A locking hole 16 provided at a position corresponding to the tapered cut-and-raised portion 13 of the cover 15 is engaged, and a cut provided inside the electrical component cover 15 corresponding to the end portion 14 of the bracket 12 is provided. The locking rib 17 having the insertion portion 18 is fixed by being brought into contact therewith.

Therefore, it can be easily and surely fixed without coming off easily by the force from the outside, the mold of the electrical component cover becomes easy, the cost is low, and the one-touch insertion can improve the workability.

[0016]

As described above, according to the present invention, the bracket is fixed to surround the glass terminal provided in the compressor body, and the electric component cover for covering the electric components is provided. There are tapered cut-and-raised portions on two opposing sides, and the electrical component cover has locking holes at positions corresponding to the tapered cut-and-raised portions provided on the bracket on the two facing surfaces. When the electrical component cover is inserted into the bracket, the tapered cut-and-raised portion engages with the locking hole, and the cut portion is brought into contact with the end portion of the bracket to complete the fixing, so that it is difficult to remove. The reliable fixing is possible, the mold of the electric component cover is easy, the cost is low, and the one-touch insertion allows the workability to be improved.
