Description
Technical field
The present invention relates to electric air-conditioning technical field, especially a kind of electric air-conditioning insulated connector.
Background technology
It is well known that compressor of air conditioner is power source, it is to complete refrigerative circle system by it.Kind of refrigeration cycle is exactly profit
With limited refrigerant in the pipe-line system of closing, repeatedly by refrigerant compression, condensation, expansion, evaporation, constantly in evaporator
Middle endothermic gasification, evaporator is remained very low temperature and be used for additional space cool-down dehumidification.Run in the market
Electric air-conditioning system, the refrigerant of use is the R407c of blending constituent, because the easy leakage characteristics of its high pressure require the pipeline of system
Connection, it is necessary to using jointless full welding metal pipe-line system, and if connected using the O-ring joint commonly used in traditional air conditioner
Connect or when rubber tube connects, due to its easy to aging, degree of being completely embedded and bear the problems such as pressure is limited, can cause slowly
R407c refrigerants leak, and especially often travel on the feelings that the poor air conditioning for automobiles of road conditions occurs joint looseness or even come off
Condition.If R407c refrigerant leakage rates reach 10%, the R407c refrigerants physical property of system will change, and this is
Absolutely not allow.Meanwhile the full welding copper pipe electric air-conditioning system run in the market, due to the power of motor compressor
Input is more than 220V high voltage, the copper pipe connection for the welding being connected with compressor, high-tension compressor have induced electricity or
During electric leakage, all parts of system can be transmitted to by the welding pipeline of system, cause security risk.In order to reduce electric leakage danger
Danger, raising air-conditioning equipment insulaion resistance is relatively low, and people develop a variety of methods, such as adds PVE lubricating oil in the refrigerant and makees to moisten
Bone agent and drier, moisture in air conditioner loop is absorbed, to reach the insulation in circulation pipe.And for example the optimization of compressor is placed and can
Connect up with being abutted against, the insulation protection of the optimization design and insulation arrangement of condenser and evaporator, advanced separation electrical equipment component
Insulation optimization design of control system etc., though take above-mentioned measure to improve air-conditioning insulation rank, due to environmental factor shadow
Ring, as contained dirt and wet steam in circulated air, flow through electric heater and compressor for a long time, its surface dirt and humidity can be made, led
Decline to its surface insulation, its insulating properties can be substantially reduced.Therefore, people are using increase screen pack or electronic precipitator, increasing
If the measures such as drying equipment increase air-conditioning insulating properties, increase equipment or component so on the one hand be present, answer air conditioner structure
Hydridization, increase air-conditioning production cost, another aspect metal circulation pipe conductivity issues Bing No itself can be solved effectively, its insulation effect
It is still undesirable.
The content of the invention
It is an object of the invention to overcome the deficiencies in the prior art, there is provided it is a kind of effectively prevent coolant leaks,
The reliable electric air-conditioning insulated connector of stable insulation.The purpose of the present invention realized by following technical proposals, this
Invention includes air-conditioning refrigerant cycle circulation copper pipe, sealing ring, fastening member, it is characterised in that：Refrigerant cycle circulation copper pipe
Interval is provided with, interval both sides copper pipe End is welded with flange core, and interval is provided with boss shape tetrafluoroethene insulating base, tetrafluoro
Ethene insulating base is provided with sealing ring with flange core phase synapsis, and tetrafluoroethene insulating base passes through brass pressing plate, insulating bushing and fastening
Component is compacted into electric air-conditioning insulated connector with the flange core on refrigerant circulation copper pipe.
Described fastening member includes fastening bolt, plain cushion, spring washer and nut.
Electric air-conditioning insulation bindiny mechanism of the present invention, has overturned the circuit design pattern of existing electric air-conditioning, has led to completely
Cross increases this mechanism in pipeline is welded, and the pipeline at mechanism both ends can insulate and separate, copper pipe is welded as one with flange core
After body, by brass pressing plate, teflon insulation bushing and fastening member by high pressure resistant resistant to elevated temperatures insulating materials polytetrafluoro
Ethene insulating base compresses, and, has certain deformation characteristic, makes itself and flange using polytetrafluoroethylmaterial material at higher pressures
Core is brought into close contact to form first of sealing, and sealing ring is provided between insulating base and flange core, forms second sealing.Brass pressing plate
Isolated insulation is carried out by polyvinyl fluoride material insulating bushing with fixing bolt.
The present invention has two seals function so that pressure-resistant, the resistance to gentle leakage prevention capability of insulated connector, is entirely capable of
Satisfaction uses design requirement of the R407c refrigerants as electric air-conditioning system, ensures that refrigerant will not leak, meanwhile, the present invention
Stable insulation, cause high voltage input compressor, with electric air-conditioning system pipeline realize insulation connection, it is ensured that electricity
Dynamic air-conditioning system, because of high voltage input compressor fault electric leakage, and cause the danger of electric air-conditioning system high pressure electric leakage.Significantly
Improve the security performance of electric air-conditioning.Other air-conditioning insulated connector of the present invention is due to using polytetrafluoroethylmaterial material, having
Certain flexibility, be advantageous to improve the effectiveness in vibration suppression of electric air-conditioning.
Brief description of the drawings
Fig. 1 is schematic structural view of the invention.
