To achieve these goals, the present invention realizes by the following technical solutions:
The thermoelectric conduction of high-precision high stable wire harness coupling arrangement; Comprise thermocouple wire, connector and be arranged on the inner high conduction metalwork of connector; It is characterized in that; Said thermocouple wire comprises the heat-resistant insulating layer of PVC material and is wrapped in first thermocouple wire and second thermocouple wire in the heat-resistant insulating layer that said connector is connected with second thermocouple wire with first thermocouple wire respectively through the high conduction metalwork;
Said first thermocouple wire is positive pin, and what its heart yearn material adopted is fine copper; Said second thermocouple wire is negative pin, and it is cupronickel that its heart yearn adopts material, has strengthened thermoelectric conductive performance, and its serviceability temperature is-200～1300 ℃, is made with special heat-resistant PVC outward.
According to the thermoelectric conduction of above-mentioned high-precision high stable wire harness coupling arrangement, wherein, what the material of said connector adopted is nylon material, and to be that phosphor bronze is gold-plated be made said high conduction metalwork.
According to the thermoelectric conduction of above-mentioned high-precision high stable wire harness coupling arrangement, wherein, be for being made by 55% copper with 45% nickel at said cupronickel; Having strengthened thermoelectric conductive performance, to make it have the linearity good; Thermopower is bigger, and is highly sensitive, and stability and homogeneity are better.
The present invention changes the inner structure and the material of wire harness under the situation that does not change script Wiring harness connector external form, has strengthened thermoelectric conductive performance and has made; It is good that it has the linearity, and thermopower is bigger, highly sensitive; Stability and homogeneity are better; Antioxygenic property is strong, and advantages such as low price can be used for the oxidisability inert atmosphere; The inner metal terminal of its connector is that the high conduction metalwork adopts the gold-plated processing of phosphor bronze, has improved the effect of thermal conductance greatly, and also can not switching performance to occur unusual even under situation for a long time, use, and phenomenons such as connector and thermocouple wire damage can not occur.
Description of drawings
Specify the present invention below in conjunction with accompanying drawing and embodiment;
Fig. 1 is a front elevation of the present invention.
Embodiment
For technological means, creation characteristic that the present invention is realized, reach purpose and effect and be easy to understand and understand, below in conjunction with embodiment, further set forth the present invention.
Referring to Fig. 1; The thermoelectric conduction of the high-precision high stable of the present invention wire harness coupling arrangement; The high conduction metalwork 3 that comprises high performance thermocouple wire 1 and connector 2 and connector 2 inside, said high-performance thermocouple wire 1 comprise that the heat-resistant PVC heat-resistant insulating layer that is made and two thermocouple wires that are wrapped in the heat-resistant insulating layer are first thermocouple wire and second thermocouple wire, and first thermocouple wire is red thermocouple wire; It is made with fine copper as positive pin; Second thermocouple wire is the white hot amphitene, and it is made with cupronickel as negative pin, and its serviceability temperature is-200～1300 ℃; This cupronickel is 55% copper and 45% nickel, and having strengthened thermoelectric conductive performance, to make it have the linearity good, and thermopower is bigger, and is highly sensitive, and stability and homogeneity are better, and antioxygenic property is strong, and advantages such as low price can be used for the oxidisability inert atmosphere.
In the present embodiment; Connector is that the good nylon material of heat-proof quality that adopts is made; And being arranged on the inner high conduction metalwork of connector, it has adopted as metal terminal, and phosphor bronze is gold-plated to be made, and makes it improve the effect of thermal conductance greatly; Even it is unusual under long-time situation about using, also can not switching performance to occur, phenomenons such as connector and thermocouple wire damage can not appear.
First thermocouple wire of present embodiment is connected with metal terminal respectively with the end of second thermocouple wire, under the situation that does not change script Wiring harness connector external form, the inner structure and the material of wire harness is changed; Change to 55% copper and 45% nickel by original aldary, having strengthened thermoelectric conductive performance, to make it have the linearity good, and thermopower is bigger; Highly sensitive, stability and homogeneity are better, and antioxygenic property is strong; Advantages such as low price can be used for the oxidisability inert atmosphere; The inner metal terminal of its connector adopts gold-plated processing, has improved the effect of thermal conductance greatly, even it is unusual under long-time situation about using, also can not switching performance to occur, phenomenons such as connector damage can not occur.
Because of thermopair directly contacts with measurand, do not receive the influence of intermediate medium, measurement range is wide.But this thermopair wire harness is from-200～1300 ℃ of equal continuous coverages, and simple structure is easy to use.Thermopair normally is made up of two kinds of different metallic silks, and does not receive the restriction of size and beginning, and protective casing is arranged outward, uses very convenient.
