Description

A kind of filament electric thermo-couple protector
Technical field
The present invention relates to instrument field, more particularly to a kind of filament electric thermo-couple protector.
Background technology
In industrial processes, temperature is to need one of important parameter of measurement and control.In temperature survey, thermoelectricity Even application is extremely wide, it has, and simple structure, easily manufactured, measurement range be wide, the little and output signal of high precision, inertia just Many advantages, such as teletransmission.In the express occasion of temperature change, the requirement to thermocouple is that thermal capacity is little, to testee or The temperature field interference of fluid is little, so generally adopt response time express thermocouple, i.e., exposed filament thermocouple, and Wish that the geometric scale for measuring contact is as little as possible.Yet with filament thermocouple thermo wires diameter in 0.05mm 0.1mm, and weld The diameter of contact is then more small, is extremely easily broken off, and this fine thermo wires be generally difficult obtain, expensive, if lose or Damage is difficult to give for change and repairs, and is inconvenient.
It is not a lot of at this stage for the resist technology of filament thermocouple, what existing technology had is processed into armour by filament thermocouple Dress filament thermocouple, greatly reduces the accuracy of measurement；Also the metal protector having is set to two cylinders, the first cylinder It is connected with nut by thread head with the second cylinder, it is very convenient to remove and install not.
Content of the invention
The invention aims to overcoming the deficiencies in the prior art, there is provided a kind of filament electric thermo-couple protector.
The present invention is to be achieved through the following technical solutions：
The present invention and a kind of filament electric thermo-couple protector, including filament thermocouple, filament thermocouple is different by two Plain conductor copper is welded with plain conductor constantan, and plain conductor copper is with plain conductor constantan by a thicker metal thermo wires Support and overlap.The thicker metal thermo wires outer cover has anti-skidding isolating shrinkable tube, the anti-skidding isolating shrinkable tube outer cover There is metal coating shell, the metal coating valve jacket has metal coating lid, the metal coating shell top has annular projection part, The annular projection section lower card has ring-type buckle.
Used as the preferred technical solution of the present invention, the plain conductor copper is needed in microscope with plain conductor constantan Lower welding.
Used as the preferred technical solution of the present invention, the thicker metal thermo wires diameter is not less than 0.3mm, with certain strong Degree.
As the preferred technical solution of the present invention, insulating materials is scribbled outside the thicker metal thermo wires, prevent metal Wire copper and the short circuit of plain conductor constantan.
Used as the preferred technical solution of the present invention, the anti-skidding isolating shrinkable tube is close to the inwall of metal coating shell, and It is not fall off.
As the preferred technical solution of the present invention, the annular projection part of the metal coating shell and the ring of metal coating lid Shape buckle can just be blocked, and be not fall off.
Used as the preferred technical solution of the present invention, the metal coating lid has elasticity with ring-type buckle.
Compared with prior art, the invention has the beneficial effects as follows：The present invention is by designing a kind of filament thermocouple protection Device, covers metal coating lid when idle so that filament thermocouple measurement end is obtained sufficiently effective protection, extends filament The service life of thermocouple, protects filament thermocouple measurement end not to be damaged；Metal coating lid is extracted during use, is directly grasped Measure.Device is compact succinct, easy to operate.
Description of the drawings
Fig. 1 is the structural representation of the present invention.
In Fig. 1：1. plain conductor copper；2. plain conductor constantan；3. thicker metal thermo wires；4. anti-skidding isolating shrinkable tube； 5. metal coating shell；6. metal coating lid；7. annular projection part；8. ring-type buckle.
Specific embodiment
In order that the objects, technical solutions and advantages of the present invention become more apparent, below in conjunction with drawings and Examples, right The present invention is further elaborated.It should be appreciated that specific embodiment described herein is only in order to explain the present invention, and It is not used in the restriction present invention.
Refer to the structural representation of Fig. 1, Fig. 1 for the present invention.
A kind of filament electric thermo-couple protector, including filament thermocouple, filament thermocouple is by two different plain conductors Copper 1 is welded with plain conductor constantan 2, and plain conductor copper 1 is with plain conductor constantan 2 by a thicker metal thermo wires 3 Support and overlap.Anti-skidding isolating shrinkable tube 4,4 outer cover of anti-skidding isolating shrinkable tube is cased with outside the thicker metal thermo wires 3 There is metal coating shell 5, the metal coating shell 5 is cased with metal coating lid 6,5 top of metal coating shell has annular projection There is ring-type buckle 8 part 7,7 bottom card of the annular projection part.
Plain conductor copper 1, the plain conductor constantan 2 of 100 μm of two suitable length diameters is intercepted, by plain conductor copper 1, gold Category wire constantan 2 is overlapped with the thicker metal thermo wires 3 for coating insulating materials and is close to thicker 3 side of metal thermo wires On wall wall, plain conductor copper 1, plain conductor constantan 2 keep certain distance so which is not contacted.
The thicker metal thermo wires 3 for having overlapped is put anti-skidding isolating shrinkable tube 4 and packs tightly, metal coating shell 5 is inserted in, is made Anti-skidding isolating shrinkable tube 4 is close to metal coating shell 5, and respectively reserves sufficient length in 5 upper and lower ends of metal coating shell, conveniently connects The filament thermocouple welding operation that gets off.
Electrolytic etching is carried out to plain conductor copper 1,2 tip of plain conductor constantan under the microscope, and forms diameter being less than 50 μm and the fine tip that has sufficient length, welded using electric spark after two nib contacts, form thermoelectricity and couple Point.So far, filament thermocouple completes.
When filament thermocouple is idle, metal coating lid 6 is buckled well with metal coating shell 5, the ring-type of metal coating shell 5 is convex The ring-type buckle 8 for part 7 being played with metal coating lid 6 can just be blocked so that filament thermocouple is obtained fully when idle It is effectively protected, the service life of thermocouple wire is extended, protects filament thermocouple measurement end not to be damaged.
When filament thermocouple needs to use, directly metal coating lid 6 is extracted from metal coating shell 5 and begins to use, Easy to operate succinct.
Presently preferred embodiments of the present invention is the foregoing is only, not in order to limit the present invention, all essences in the present invention Any modification, equivalent and improvement that is made within god and principle etc., should be included within the scope of the present invention.
