Description
Technical field
What the present invention relates to is compressor, particularly be the power of compressor supplier.
Background technique
In general, the compressor that constitutes refrigerating circulation system is that the refrigerant of the low-temp low-pressure state that will flow into from vaporizer is compressed into behind the refrigerant of high-temperature high-pressure state the machine with its discharge.
Above-mentioned compressor can be divided into rotary compressor according to the mode of compressed fluid, reciprocating compressor, several types of turbocompressor etc.Wherein rotary compressor is by the refrigerant in the running shaft compression cylinder of rotation, running shaft in this rotary compressor and the rolling piston interlock that is installed in the running shaft lower eccentric make its inner peripheral surface corotation and moving of rotation along cylinder suck the also machine of compression refrigerant.
This rotary compressor is as depicted in figs. 1 and 2, and it specifically is made of following several parts:
Be formed with the space of sealing in inside, and suction port 1 and exhaust port 2 are arranged, suck and discharge the seal container 10 of refrigerant with this;
By being installed on above-mentioned seal container 10 inside, and produce the power driving part 20 of rotating forces by interactional stator 21 and rotor 22;
Connect above-mentioned power driving part 20 and obtain power and drive, and be installed on the driven compressor portion 30 that seal container 10 internal compression suck refrigerant;
Connect the suction port 1 of above-mentioned seal container 10, and will suck the accumulator 40 that the impurity that contains and liquid coolant are removed in the refrigerant of above-mentioned compressor drive portion 30.And, be equipped with at the upside of seal container 10, connect the power supply joint 60 of above-mentioned power driving part 20 external power supplys.
Above-mentioned power supply joint 60 is by constituting as lower member:
Be installed in the casing 61 of above-mentioned seal container 10;
Be formed on the inside of said machine casing 61, and be incorporated into each attachment plug 62 of a side with the stator 21 wire connecting 21a of above-mentioned power driving part 20;
Be connected in the opposite side of above-mentioned attachment plug 62, and protrude in the outside of above-mentioned seal container 10, and then be inserted into the contact terminal 63 of outside terminal 64 the insides that connect external power supply.
Above-mentioned compressor drive portion 30 is by constituting as lower member:
Be pressed into and be installed on above-mentioned rotor 22 inside, the bottom is formed with eccentric part 31a, and has the running shaft 31 of circular cross section;
Above-mentioned eccentric part 31a is contained in inside, and the upper bearing 32 and the lower bearing 33 that support above-mentioned running shaft 31 be connected and fixed by screw 34, in the cylinder 35 that is installed in above-mentioned seal container 10 inside of aspirating unit 35a;
Inner face is connected to the eccentric part 31a that is formed on above-mentioned running shaft 31 1 sides mutually, and the outside is connected to the inner face of above-mentioned cylinder 35 mutually, and does the rolling piston 50 of revolution and spinning motion along with the rotation of above-mentioned eccentric part 31a;
Contact with slide type with the outer circumferential face of above-mentioned rolling piston 50, and the inside of above-mentioned cylinder 35 is divided into zone of high pressure and low pressure area, and be installed on turbine leaf 37 in the above-mentioned cylinder 35 along the central direction straight reciprocating motion of above-mentioned cylinder 35.
Apply power supply for above-mentioned rotary compressor, because the interaction of stator 21 and rotor 22 makes rotor 22 and running shaft 31 rotations.Because the rotation of the eccentric part 31a of running shaft 31 1 sides, rolling piston 50 will contact with turbine leaf 37 in the inside of cylinder 35 and rotate, by above-mentioned rotation, via the refrigerant boil down to high-temperature high-pressure state of the low-temp low-pressure of above-mentioned accumulator 40 suctions.
Supplying electric current process to above-mentioned rotary compressor more describes in detail below: the contact terminal 63 that protrudes in the power supply joint 60 of above-mentioned seal container 10 outsides is inserted in the middle of the outside terminal 64 that is connected with external power supply, promptly outside terminal 64 is connected with contact terminal 63.Like this, make external power supply supply to contact terminal 63 by outside terminal 64.And then supply in the stator 21 of seal container 10 inside by attachment plug 62 that is connected in above-mentioned contact terminal 63 and the electric wire 21a that is connected in the attachment plug 62 again.Then, the interaction by stator 21 and rotor 22 produces rotating force.
But, the rotary compressor of above-mentioned existing structure, because the contact terminal 63 of power supply joint 60 is outstanding to the outside, is making or existing in the keeping process time because impact or external force make the phenomenon that power supply joint 60 is crooked or damage, thereby normal production is adversely affected.
