In Fig. 1,, motor (not shown) and compressing mechanism (not shown) are housed in seal container 2 inside of hermetic compressor 1.
Seal container 2 has upper casing body 3 and lower casing body 4.
Above-mentioned compressor structure portion and motor are packed into behind the lower casing body 4, cover upper casing body 3, again by welding with its joining portion 5 sealings.
In upper casing body 3, the glass terminal part 6 to built-in motor power supply usefulness is installed.
Fig. 2 is the amplification view of glass terminal part 6 among Fig. 1.
In Fig. 1 and Fig. 2, upper casing body 3 is provided with the par, and the periphery of glass terminal part 6 is by the sealed welding of resistance welding.
Terminal 7 is by glass 8 relative housing section insulated enclosures.
On the surface of glass terminal part 6, be coated with the electrically insulating material of silicone oil and so on.
Plug-in unit 10 inserts glass terminal part 6, from externally fed.
Plug-in unit 10 is provided with starter relay with being integral.

In Fig. 3, bimetal 19 predicts the temperature (predicting the temperature of built-in motor indirectly) of compressor top, and by flowing through the effect of electric current, and break 20 when overload plays the electric current of sever supply compressor 1.
That is, OLP14 has the effect of the control mechanism used of control compressing mechanism.
In seal container 2, refrigeration agent is housed.
Below when refrigeration agent is heavier-than-air combustible refrigerants such as propane or isobutane, this refrigeration agent describes from the situation of sewing that hermetic compressor spills.
Hermetic compressor 1 carries out leakage examination under its design pressure.
Leakage examination generally is to put into air in compressor, and in its immersion water, the portion of sewing has or not bubble to judge according to this moment.
Or in compressor, charge into helium and judge that with prober atresia is arranged.
Generally sewing many parts is welded joint 5.
The welding method of this welded joint 5 generally adopts the TIG welding in inert gases such as argon gas or carbon dioxide.
Sewing easily that bigger hole produces in the joining portion 5 is found.
Yet the pore that the gas that produces during because of welding causes is trickle, and the oxidized skin of pore stops up under many circumstances.Therefore, fine holes is difficult to find.
The compressor 1 that also has is that this scale comes off, and just begins after the several years to sew after using over a long time.
The pore that can not find in leakage examination is minimum pore.
The amount of the refrigeration agent of sewing from this minimum pore is below 1cc/min.
Therefore, this to sew speed extremely slow.
The refrigeration agent (the heavier-than-air refrigeration agent of proportion) that spills from pore slowly spreads around this pore.
Because refrigeration agent is heavier than air, so the refrigeration agent that spills flows downwards and diffusion.
Combustible refrigerant is a hydrocarbon if then can not ignited to certain ratio with air mixing.
For example propane is LEL=2% and UEL=10%.
That is, the relative Air mixing ratio of propane can catch fire or explode in the scope of 2%-10% the time, but concentration is outside this scope the time, and the refrigeration agent that spills can not ignited.
On the other hand, the ignition source around the compressor is mounted in the starter relay (when adopting connecting-point type) of glass terminal part 6 and the contact of OLP14.
In the present embodiment, welded joint 5 is configured in the position under the glass terminal part 6 that relay etc. is housed.
And this glass terminal part 6 has the possibility that becomes ignition source.
The inflammable gas that spills from the pore of welded joint 5 slowly flows downward and spreads.
Therefore, the refrigeration agent that spills can not contact with the terminal part 6 that can become ignition source.
Perhaps, even under the refrigeration agent that spills and situation that terminal part 6 contacts, the amount that the refrigeration agent that spills contacts with OLP14 is also few.
Therefore, combustible refrigerant and Air mixing are than not reaching flammable concentration.
Its result can obtain safe refrigerating air conditioning device and compressor.
In addition, the control electric component is the top that OLP14 is configured in welded joint 5.
This OLLP14 has the possibility that becomes ignition source.
The inflammable gas that spills from the pore of welded joint 5 slowly flows downwards and diffusion is come.
Therefore, the refrigeration agent that spills can not contact with the OLP14 that becomes ignition source.
Perhaps, even under the refrigeration agent that spills and situation that OLP14 contacts, the amount that the refrigeration agent that spills contacts with OLP14 is also few.
Therefore, combustible refrigerant and Air mixing are than not reaching flammable concentration.
Its result can obtain safe refrigerating air conditioning device and compressor.
In the weld job of upper shell 3 and lower shell body 4, weld job finishes at starting point 5a after a week from starting point 5a.
Therefore, change, and starting point 5a and end point are overlapping when welding finishes in starting point 5a welding condition.
Therefore, the pore at welded joint 5 places occurs near the starting point 5a especially easily.
The position of welding starting point 5a preferably is configured in away from the position of OLP14 or the opposition side of seal container 2.
Because have the starting point 5a of likelihood of leakage and ignition source be OLP14 be positioned at mutually away from the position, so near OLP14, combustible refrigerant and Air mixing are than not reaching flammable concentration.
Its result can obtain safe refrigerating air conditioning device and compressor.
In addition, the part that refrigeration agent is sewed may take place, be the pore that occurs in the glass 8 of glass terminal part 6.
Because of the pore that the tiny bubble in the glass 8 causes, when carrying out leakage examination, be difficult to find.
In order to cover like this pore that takes place at glass portion 8, be the center with the surface of glass 8, be coated with the insulating material 9 of silicone rubber, silicone oil etc.
Because this structure can prevent to spill refrigeration agent from the glass 8 of glass terminal part 6.
Have again, even have under the situation that refrigeration agent sews at glass terminal part 6 places, because covering the OLP lid 17 that the wiring terminal lid 12 of glass terminal part 6 covers OLP14 relatively is independent settings, so the refrigeration agent that spills from glass terminal part 6 can not contact with the OLP14 that can become ignition source.
Therefore, near OLP14, combustible refrigerant and Air mixing are than not reaching flammable concentration.
Its result can obtain safe refrigerating air conditioning device and compressor.
In the present embodiment, wiring terminal lid 12 adopts mutually independently lid with OLP lid 17, but also can adopt a lid and within it portion dividing plate is set.
OLP lid 17 is configured in the upside of wiring terminal lid 12.
The refrigeration agent of heavier-than-air flammable propane and so on flows downwards and diffusion is come.
Therefore, cover 17 inside at OLP, combustible refrigerant and Air mixing are than not reaching flammable concentration.
Its result can obtain safe refrigerating air conditioning device and compressor.
