Description
Technical field
The utility model belongs to thermocouple sensor design field, and in particular to a kind of flexibility multi-measuring point thermocouple junction
Structure.
Background technique
For the mean temperature for measuring the section combustion gas of aero-engine temperature, conventional junction as shown in Fig. 3 is generallyd use
Structure, specially using the structure of collector ring and several single branch thermocouples, collector ring passes through lug plate and nut and thermocouple
Binding post is fixedly connected, by thermocouple signal parallel output.Structure dismounting is complicated, is unfavorable for the maintenance of engine, Er Qieji
The junction of electric ring and thermocouple is exposed structure, is not suitable for the environment high applied to EMC Requirements.
There is also rigid multi-measuring point thermocouples at present, as shown in Fig. 4.The thermocouple of such structure not only processes complexity,
Installation maintenance is difficult, and use scope is limited to, and applies on the engine that section radius is small, power is small more.
Utility model content
A kind of the purpose of the utility model is to provide structures flexible multi-measuring point thermocouple structure simple, easy for installation, and
The environment high suitable for EMC Requirements.
In order to realize above-mentioned purpose of utility model, the utility model provides the following technical solution: a kind of flexible more surveys
Point thermocouple structure, including thermocouple, flexible compensation cable, metallic wiring box, output end socket, wherein thermocouple and corresponding pole
Property flexible compensation cable welding, several flexible compensation cables are connected in parallel in metallic wiring box, it is in parallel after compensation
Conducting wire is connect with output end socket.
Preferably, the thermocouple and flexible compensation cable use the material with indexing, ensure that the precision of measurement.
Preferably, the outside of the flexible compensation conducting wire is equipped with stainless steel metal wired tube, plays the work of electromagnetic shielding
With.
Preferably, the metallic wiring box is the can of sealing, nonmetallic materials is filled in box, for sealing and fixing
Flexible compensation conducting wire.
The utility model beneficial effect achieved is: the utility model using all-metal sealing structure multi-measuring point
Thermocouple, resistance to Electromagnetic Compatibility is high, and the market competitiveness is strong, has a extensive future.
In material selection, original aviation armoured thermocouple cable is replaced using compensating cable flexible, is not only passed through
Ji property is good, and simple process, and from being bent, being heat-treated, the production cycle is also greatly improved.
In installation, flexibility multi-measuring point thermocouple provided by the utility model will not generate interference because of pipeline, more
It will not be confined to the radius of engine.
In addition, metallic wiring box is installed on the cold end of engine, mainly it is made of nonmetallic materials inside metallic wiring box.
It is limited to 300 DEG C of nonmetallic materials and connector for most of High-temperature-respolent polent, can satisfy in the environment of engine cold end
Requirement.

Specific embodiment
It elaborates with reference to the accompanying drawing to this patent:
A kind of flexible multi-measuring point thermocouple structure as shown in Figure 1 and Figure 2, thermocouple 1 are mended with corresponding polar flexibility
It repays cable 2 and carries out the logical welding of silver, guarantee that connection is reliable.The thermocouple 1 and flexible compensation cable 2 are using the material with indexing.
The outside of the flexible compensation conducting wire 2 is equipped with stainless steel metal wired tube.
Several flexible compensation cables 2 are connected in parallel in metallic wiring box 3, then by after parallel connection conducting wire and output
Socket 4 corresponding polar contact pin in end is welded, and the mean temperature of section combustion gas is exported by output end socket 4, guarantees thermoelectricity
The signal output engine control system of gesture.
The metallic wiring box 3 is the can of sealing, the nonmetallic materials such as filled silicon rubber in box, for sealing and consolidating
Determine flexible compensation conducting wire 2.
The metallic wiring box 3 is installed on cold end, is protected from the influence of engine high-temperature environment, be conducive to connector and
The selection of nonmetallic materials.
