In FIG. 3, a hermetic compressor 1 has an electric motor and a compressor main body housed in a container or shell 3 supported by legs 2 protruding around the bottom surface, and the outer surface of the hermetic compressor 1
Only the terminal box 4 is visible. FIG. 4 shows III in FIG.
FIG. 5 is an enlarged view of a portion, and FIG. 5 is a cross-sectional view taken along the line IV-IV in FIG. 4. As can be seen from these, the gasket 5 is closely attached to surround the hole through which the glass terminal 6 penetrates, A terminal box 4 is provided so as to surround this. The terminal box 4 is fixed to the shell 3 by spot welding or the like, but a gap between the two is closed by a gasket 5. The glass terminal 6 connected to the cable of the electric motor (motor) penetrates the shell 3,
This is surrounded by a gasket 5, and terminals of lead wires 7a and 7b are inserted and attached to the terminal studs.
These are protected by a box-shaped cover 8 (hereinafter also referred to as a box cover) having holes through which the lead wires 7a and 7b pass, and the box cover 8 is removed at the time of inspection or the like.

However, in the former hermetic compressor, although the terminal box 4 is mounted on the shell 3 of the hermetic compressor via the gasket 5, the hermetic compressor Not only is it a separate member from the shell 3, but is also a separate member from the box cover 8. Therefore, if no special measures are taken, there is a possibility that a small gap will occur, and the inside of the box cover 8 will be exposed from the outside. Moisture, dust, and the like enter and adhere to the terminal studs of the glass terminal 6 and cause an electrical trouble. On the other hand, according to the latter terminal box structure, since each terminal stud itself is embedded with the silicone rubber in the storage cover, the above-mentioned inconvenience is improved, but at the time of assembling the terminal box so as not to shift due to vibration etc. Since a separate means for firmly fixing the storage cover is required and water and dust are allowed to enter the terminal box, if the insulation by silicon rubber is broken for some reason, electrical trouble will occur. The possibility is high. Therefore, the present invention provides a terminal box structure of a hermetic compressor that has good sealing performance so that moisture and dust do not enter the terminal box, and does not cause insulation failure, contact failure, etc. due to dew condensation at the wire connection portion. It is intended to be provided.

According to the above-mentioned structure, since the gasket and its cylindrical wall, which are in close contact with the outer surface of the shell, surround the terminal portion and its connecting terminal pins, the sealing material filled in the cylindrical wall is free from moisture, dust and the like. Even if the flow is completely cut off and the temperature of the shell is lowered, dew condensation does not occur on the connection terminal pins, and dew condensation occurs on the outer surface of the filling sealing material and the outer peripheral surface of the cylindrical wall. Moreover, since the cylindrical wall is surrounded by the box-shaped cover, the connecting terminal pin is doubly protected, and even if the insulation due to the filling sealing material inside the cylindrical wall is broken, the connecting terminal pin will be damaged to some extent. Can be protected. In this way, the electricity from the lead wire completely flows from the connection terminal pin to the internal electric motor via the terminal portion.

As shown in FIG. 2 in particular, a rectangular tubular terminal box 17 which is open at both ends and surrounds the gasket 15 is fixed to the compressor shell 11 by spot welding through its tongue portion 17a, and its bottom surface. Holes 17b and 17c for passing lead wires are formed in the. The box cover 19 to be inserted into the terminal box 17 has spring hooks 19a integrally formed on both sides thereof. As can be understood from FIG.
When each of the spring hooks 19a is inserted into the terminal box 17, each spring hook 19a is engaged with and fixed to the slots 17d on both sides of the terminal box 17. And the terminal box 17
The ends of the lead wire 21 passing through the holes 17b and 17c are engaged with the connection terminals 13d and 13e, and the contact portion is filled with a sealing material 23 such as a silicone sealant from above. The sealing material 23 is filled up to the outer end of the cylindrical wall 15a, and the lead wire 21 extends through the notch of the cylindrical wall 15a, the bottom notch 19b of the box cover 19 and the holes 17b and 17c of the terminal box 17. I have put it out.

As described above, the sealing material 23 covers the connecting terminals 13d and 13e so that the cylindrical wall 1 of the gasket 15 is covered.
Since it is filled in the inside of 5a, even if moisture or the like enters through the box-shaped cover 19, it prevents them from entering the inside of the cylindrical wall 15a, and around the connection terminals 13d, 13e. No condensation occurs. Therefore, electrical troubles such as abnormal contact and poor insulation can be effectively prevented. Then, if the box cover 19 is pulled outward while pushing the spring hook 19a from the outside with a finger, it can be easily removed, and it is easy to determine whether or not a crack due to the sealing material 23 or a gap due to poor adhesion is generated. To be inspected.
