Abstract
The present invention discloses a hermetic compressor, which comprises a sealing terminal and a bunch collector, wherein the sealing terminal passes through a casing body of the compressor and can supply an external power supply to an electric mechanical part positioned in an inner space of the casing body; the bunch collector can be used for firmly sealing an outer circumferential surface at one end of the sealing terminal and electrically connected between the sealing terminal and the electric mechanical part arranged in the inner space of the casing body. The hermetic compressor can prevent foreign bodies in lube or oil from flowing into the sealing terminal and the bunch collector when the compressor operates by firmly sealing a gap between the sealing terminal and the bunch collector, so that short circuit problems are caused among terminal pins or among terminals. Therefore, the reliability of the compressor can be improved.

Embodiment
Below in conjunction with the drawings and specific embodiments closed compressor provided by the invention is elaborated.Represent that as Fig. 4 and Fig. 1 closed compressor provided by the invention comprises the inner space with sealing, and be provided with the housing 1 of electromechanical part and compression mechanical portion in the inner space; Be arranged on the upper end of housing 1, external power supply can be offered the sealed terminal end 10 of electromechanical part; With with near the sealing combinations of states on sealed terminal end 10, the lead that electromechanical part can be drawn is connected to the buncher 20 on the sealed terminal end 10.Can weld after making sealed terminal end 10 be inserted in the housing 1, sealed terminal end 10 adopts metallic material to make; And for sealed terminal end 10 can be inserted on the buncher 20, buncher 20 adopts the plastic materials with heat-shielding performance to be processed into.In addition, buncher 20 can also adopt to have the sheet metal of heat-shielding performance or be coated with thermal-protective coating on the common metal plate and make according to different situations.
As shown in Figure 4, described sealed terminal end 10 comprises the housing 1 that runs through compressor and the cylindrical shape terminal fixing part 11 that is provided with; Be arranged on the disc pin fixing part 12 at terminal fixing part 11 bosom positions with sealing.Described pin fixing part 12 is integrally formed with terminal fixing part 11, and perforation is provided with a plurality of terminal pin ones 3 that are used to connect external power supply and coil 5 on the pin fixing part 12.
To shown in Figure 6, described buncher 20 comprises the box body portion 21 of common employing four directions body structure as Fig. 4; Integrally formed with box body portion 21, can cover the covering part 22 of terminal fixing part 11 1 end openings on the sealed terminal end 10; With from the bending of the external margin of covering part 22 and integrally formed, and can be close to the connecting part 23 on the terminal fixing part 11 1 end outer, circumferential edge on the sealed terminal end 10.In addition, be formed with a plurality of pin hole 21a in the box body portion 21, can insert the terminal pin one 3 on the sealed terminal end 20 thus, and the inboard of pin hole 21a is provided with not shown can linking to each other with the lead-in wire of coil 5, thus a plurality of terminals that coil 5 is electrically connected with sealed terminal end 10.In addition, described covering part 22 adopts the roughly the same disc-shaped structure of external diameter of diameter and terminal fixing part 11.Connecting part 23 is outstanding and form with the shape of annulus roughly from the outer, circumferential edge of covering part 22, and for the inner peripheral surface of connecting part 23 can be close on the outer peripheral surface of terminal fixing part 11, the external diameter of the internal diameter of connecting part 23 and terminal fixing part 11 is roughly the same.In addition, when buncher 20 seals up the inner space of sealed terminal end 10, the inner space of sealed terminal end 10 just might produce moisture, therefore in order to discharge moisture, as shown in Figure 7 and Figure 8, the part-structure of connecting part 23 and the outer, circumferential edge of sealed terminal end 10 can be spaced from each other certain distance, promptly on connecting part 23, be bent to form opening portion 24.The structure identical with prior art used identical label among the figure.
Closed compressor working procedure provided by the invention with said structure is as follows: after the compressor starts running, be contained under the centrifugal action that the lubricant oil of housing 1 bottom will produce when the rotation of electromechanical part and compression mechanical portion and upwards suction, wherein a part of lubricant oil will offer compression mechanical portion along the running shaft of electromechanical part, another part lubricant oil will disperse in the upper end of running shaft, thus cool motors tool portion.Because the residual foreign matter that produces when the assemble compressible machine is arranged in the lubricant oil, so these foreign matters will disperse to the inner peripheral surface of housing 1 with lubricant oil.In this process, lubricant oil and foreign matter also can flow into power supply unit, promptly flow between sealed terminal end 10 and the buncher 20, therefore might make each terminal pin one 3 of sealed terminal end 10 or the terminal of buncher 20 produce short circuit phenomenon.But in the present invention, because the connecting part 23 of buncher 20 surrounds and seal up the terminal fixing part 11 of the sealed terminal end 10 that is arranged in housing 1 inner space, can prevent from thus to enter between sealed terminal end 10 and the buncher 20 from the lubricant oil and the foreign matter that disperse in the running shaft upper end.
In addition, in a last embodiment, buncher 20 is to be inserted on the sealed terminal end 10 and to interfix, and as shown in Figure 9, in the present embodiment, for buncher 20 is arranged on the sealed terminal end 10 more securely, on an end outer, circumferential edge of terminal fixing part 11, form fixed groove 11a, simultaneously with the inner peripheral surface of the corresponding connecting part 23 of fixed groove 11a on form the fixed projection 23a that can cooperatively interact with fixed groove 11a on the sealed terminal end 10.
And, in a last embodiment, be formed with the opening portion 24 of bending laterally on the connecting part 23 of buncher 20, but in the present embodiment, as shown in figure 10, whole connecting part 23 is closely linked with the terminal fixing part 11 1 end outer, circumferential edge of sealed terminal end 10, at this moment, more than one through hole 25 should be set on the covering part 22 at least, discharge moisture or dispel the heat being used to.Therefore, in the running of compressor, therefore the terminal pin one 3 of sealed terminal end 10 or the terminal of buncher 20 just can not improve the reliability of compressor because of foreign matter causes short circuit.
