があった。The conventional electrical protection device for refrigerator compressors was developed in 1982.
As in the conventional example of Publication No. 17877, the starting device and overload protection device were installed separately on the compressor and then the protective cover was attached, but with the automation of one assembly and speeding up of production, there is a strong need to install one. , Said Utility Model Publication No. 56-178
77, as shown in Fig. 3, the starter device 15 and overload protection device 16 are integrally attached to the protective cover 18 using the mounting base 17, and then attached to the compressor. is a semi-finished product when used alone, and the terminal fitting 19.1
9 and the electrode holder 20 together with the mounting base 17 to complete the product, the work process is complicated and the starting device 15. Terminal section 15a during characteristic test of overload protection device [16]
, 16a cannot be electrically connected using a simple method such as an insertion type, so a clamping method using a clip must be used, which is difficult to automate. . In addition, there is a starting bag fi in the protective cover 18! There are 15 fitting holes 18a, and a waterproof protector was provided on the compressor outer shell to prevent water from entering the protective cover 18 during a water injection test assuming that the compressor would be exposed to water. However, with the recent downsizing of compressors and the adoption of horizontal rotary systems, the area of the starting device has become smaller.
There was no room to install a protector above the protective cover 18, and the conventional electrical equipment protection device described above was no longer satisfactory. In addition, the protective cover 18 of the above conventional example. Initially, the moving device 15 and the mounting base 17 were installed by providing a locking rib 18b inside the protective cover 18 and hooking the locking rib 18b onto the side surface 17a of the mounting base.
Starting equipment f! 15 and the protective cover 18, the spring for attaching the compressor to the starter was locked to the upper part 15b of the starter, and the fitting force 18a of the protective cover 18 could not be eliminated. Furthermore, since the locking rib 18b is tapered in the opposite direction to the die-cutting direction, the locking rib 18b portion is used as a split mold and the die is removed by sliding, which takes time to mold the protective cover 18 and increases costs. The drawback was that the mold life was short.
