Form of implementation 1
Fig. 1 is the longitudinal section as the scroll compressor of an example of the cold medium compressor of form of implementation 1 of the present invention.
In Fig. 1, seal container 10 is by housing section 10d cylindraceous, last cover end plate 10e, and following cover end plate 10f constitutes.The motor part 7 that accommodates compression mechanical parts 1 such as being equipped with fixed scroll and swing vortex and be equipped with the motor that is made of stator, rotor in seal container 10, compression mechanical part 1 is connected by live axle 8 with motor part 7.In compression mechanical part 1, utilization is passed to the rotation of live axle 8 the low pressure refrigerant gas that suction pipe 3 sucks is compressed by motor part 7, be discharged in the seal container 10 by exhaust port 1f as pressurized gas.Seal container 10 inside of configuration motor part 7 are full of high pressure refrigerant gas, become high-pressure atmosphere, and this cold media air is discharged to by the discharge tube on the housing section 10d that is configured in seal container 10 4 in the refrigeration cycle of outside of seal container 10.
The hermetic terminal 6 (expressing one of them among Fig. 1) of three minor diameters of configuration on the housing 10d of seal container 10.Motor part 7 is accepted the power supply of three phase mains from hermetic terminal 6.
In addition, the mounting hole formation portion that suction pipe 3, discharge tube 4 are installed on the outer wall of seal container 10 is carried out plunging processing (representing that with label 12 plunging adds the Ministry of worker in Fig. 1), mounting hole formation portion is bigger than the other parts thickness of outer wall.
Other structural element is identical with the situation of prior art shown in Figure 7, and gives identical label, omits its explanation.
Fig. 2 A～2C is the diagram that is used to illustrate the hermetic terminal of form of implementation 1 of the present invention, Fig. 2 A is the sectional view of hermetic terminal, Fig. 2 B is the allocation plan that the pin of hermetic terminal is configured to a line, and Fig. 2 C is configured in allocation plan on the leg-of-mutton drift angle to the pin of hermetic terminal.
In Fig. 2 A～2C, the hermetic terminal 6 of this form of implementation is that three single-phase terminals 6 littler than the diameter of the hermetic terminal 5 of the three-phase integrated formula of prior art are configured on the seal container 10.
Single-phase terminal 6 diameters are less, and its structure is, are configured on the circular metal base 6a being connected to the pin 6b that one in the three phase mains go up mutually, utilize glass 6c to carry out glass sealing between this pin 6b and the metallic base 6a, make it to constitute electrical insulation.Single-phase terminal 6 usefulness electric welding are welded on the mounting hole 10a of diameter on the outer wall of the housing section 10d that is located at seal container 10, substantially the same with the 6a of metallic base portion, guarantee the tightness between seal container 10 inside and outside.
The collocation method of three single-phase terminals 6, shown in can image pattern 2B like that along circumferential direction configuration one row of seal container 10, also can image pattern 2C such, be configured on the position of drift angle of equilateral triangle.
Like this, by dwindling the diameter of hermetic terminal 6 (single-phase terminal 6), can suppress the ovalizing deflection of the terminal mounting hole 10a of distortion along with the cydariform distortion of seal container 10.Simultaneously, because itself dwindling its rigidity, hermetic terminal 6 increases, thereby can suppress because the bloating laterally that internal pressure causes, and, the stress that is added on the insulating glass 6c of 6a of metallic base portion and pin 6b reduces, thereby increase the compressive strength of hermetic terminal of single-phase terminal 6 and the compressive strength of assembly department, play a part to improve the whole compressive strength of seal container 10.
Fig. 3 A is illustrated under the situation that this hermetic terminal 6 is installed when carrying out the hydrostatic pressing overload test, the breakdown strength of seal container 10 (in this hydrostatic pressing overload test, at suction pipe assembly department and discharge tube assembly department application of load not).On Fig. 3 A, provided the breakdown strength of the three-phase integrated formula hermetic terminal 5 of prior art, during line of three single-phase terminals, 6 configurations, and the comparison of the breakdown strength when being configured in three positions of drift angle of equilateral triangle.
Breakdown strength at the hermetic terminal 5 of the three-phase integrated formula of prior art is hydrostatic pressing 18MPa, and is relative therewith, and under the situation of the hermetic terminal 6 of this form of implementation, its breakdown strength is 25MPa, and intensity improves 40% approximately.In addition, collocation method for single-phase terminal 6, under the situation that three terminals is become row along circumferential array, with three terminal arrangement are compared in the situation at the drift angle place of equilateral triangle, compressive strength when single-phase terminal 6 being configured on the drift angle of equilateral triangle is 22MPa, and the intensity of the aforementioned 25MPa than along circumferential direction configuration one row the time is little.
When being configured in single-phase terminal 6 on this drift angle, shown in Fig. 3 (b), its destruction is to cause owing to produce be full of cracks 11 each other at the different terminal mounting hole 10a of the height of axial direction, shows that mounting hole 10a is provided with better along the installation of circumferential direction level.But even single-phase terminal 6 is configured on the corner position, its intensity is also than the intensity height of the hermetic terminal 5 of the three-phase integrated formula of prior art.
In addition, the collocation method of three single-phase terminals 6 on seal container is not limited to aforementioned two kinds of configurations, described three single-phase terminals 6 are configured in be convenient to be connected with three phase mains, can not hypertelorism, while apart can not be too near in order to ensure its intensity, they is configured in make the balanced mutually position of two distances can obtain good effect.
Fig. 4, Fig. 5 are respectively the explanatory drawing that expression suction pipe and discharge tube are installed to the state on the housing 10d of seal container shown in Figure 1 10.
Among Fig. 4 and Fig. 5, respectively as the connecting tube 3a of suction pipe 3 and discharge tube 4, mounting hole 10b on the seal container 10 of the assembly department of 4a, the front end of the mounting hole formation portion of 10c carries out plunging processing (at Fig. 4, represent that with label 12 plunging adds the Ministry of worker among Fig. 5) formation mounting hole 10b, 10c.
By carrying out plunging processing, make connecting tube 3a, the mounting hole 10b of 4a, near the 10c thickness (mounting hole formation portion) is so can suppress the mounting hole 10b that the cydariform distortion because of seal container 10 causes greater than the thickness of other outer wall section of seal container, the ellipse distortion of 10c, and suppress connecting tube 3a, the welding of 4a is broken, so plunging processing can play a part to improve the compressive strength of seal container 10.
In addition, the same with plunging processing, end before the mounting hole is crooked laterally, increase its thickness, suction pipe 3 is installed again, discharge tube 4 also can obtain substantially the same effect.
Fig. 6 is compressive strength with the hydrostatic pressing overload test result's of the seal container 10 that does not carry out the prior art that plunging processes of the expression seal container 10 that suction pipe 3 is installed to the mounting hole 10b that carried out plunging processing a comparison diagram (in this hydrostatic pressing overload test, on hermetic terminal assembly department and discharge tube assembly department not application of load).
Because the intensity of the mounting hole 10b by plunging processing connecting tube 3a increases, and has suppressed oval distortion, so become the 25Mpa of this form of implementation from the hydrostatic pressing of the 20MPa of prior art, compressive strength improves about 25%.
For discharge tube 4, its hydrostatic pressing overload test obtains same result.
In addition, the thickness thickening by plunging processing mounting holes formation portion, even suction pipe 3 and discharge tube 4 respectively without connecting tube 3a, 4a directly is installed to mounting hole 10b, on the 10c, also can obtain enough compressive strengths.
