As shown in figure 4, a kind of preparation method of thermocouple cored wire connection component 22, the system are additionally provided in present embodiment
Preparation Method comprises the following steps：
Step S110, the trouble location of the first connector 100 is cut off from root, separate part the first cathode core 110 and
Part the first anode core 120.Trouble location is usually the plug position being connected with another thermocouple junction, cuts trouble location
Afterwards, the insulated hull of 8cm is inwardly peelled off since being cut position, to expose the first armouring shell 130.In the first armouring shell 130
Distance cuts and marks at the 1cm of position, and the first armouring shell 130 of this 1cm long is cut away with pipe cutter, exposes by the first armour
The both threads core that casing 130 coats, namely the first cathode core 110 and the first anode core 120.Both threads core is measured respectively
Length, ensure the exposed length of both threads core be 7-9mm.The magnesia of both threads wicking surface will be remained in sand paper again
Powder is cleaned out, in order to avoid influence subsequently to be electrically connected with second connector 200.
The first cathode core 110 contacts with the first anode core 120 and causes short circuit in order to prevent, can be after dicing
Groove is touched out in the end of first armouring shell 130, manufactured first adhesive 510 is filled in groove so that the first glue
Stick 510 separates the first cathode core 110 and the first anode core 120.
Step S120, separates part the second cathode core 210 and part the second anode core 220, method and step
S110 is identical, just repeats no more here.It is equally possible that fill the second adhesive in the end of the second armouring shell 230
520。
Step S130, welds the first cathode core 110 and the first connecting tube 300, welds the first anode core 120 and second
Connecting tube 400.
Step S140, welds the second cathode core 210 and the first connecting tube 300, welds 220 core of the second negative line and second
Connecting tube 400.
In appearance, the first cathode core 110 is identical with the first anode core 120, the second cathode core 210 and second negative
Polar curve core 220 is identical.To prevent reversed, the magnetism of each core and each connecting tube can be first detected before welding.With the first connector 100
Exemplified by, utilize the magnetism of the first cathode of embroidery needle check core 110 and the first anode core 120, it is assumed that the result of detection is the
One cathode core 110 has magnetism, and the first anode core 120 then carries out magnetic first cathode core 110 without magnetism
Mark.Again with embroidery needle check the first connecting tube 300 and the magnetism of the second connecting tube 400, it is assumed that the result of detection connects for first
Adapter 300 has magnetism, and magnetic first connecting tube 300 is then carried out mark by the second connecting tube 400 without magnetism.Welding
When, it will just be welded, not had markd with markd first cathode core 110 and with markd first connecting tube 300
First anode core 120 and do not have markd second connecting tube 400 to be welded.Confirm the second cathode core with same method
210 and second anode core 220 magnetism, then complete the second connector 200 and the first connecting tube 300 and the second connecting tube 400
Welding.
Step S150, insulator 600 is arranged in by the first connecting tube 300 and the second connecting tube 400.Put on for convenience absolutely
Insulator 600, can first be through in the first connecting tube 300 and the second connecting tube 400 by edge body 600 after step s 130, and
So that insulator 600 is close proximity to the first armouring shell 130, in order to avoid influence the execution of step S140.After completing step S140, then
Insulator 600 is pushed into middle part, protects solder joint everywhere.
In other embodiments, can also be set on insulator 600 the first notch for being connected with first through hole and
The second notch connected with the second through hole, the circumferential size of the first notch are less than the diameter of the first connecting tube 300, the second notch
Circumferential size is less than the diameter of the second connecting tube 400.Insulator 600 is made of rubber, has certain elasticity, is performing step
, can be by the first connecting tube 300 out of the first indentation, there push-in first through hole, by the second connecting tube 400 from second after rapid S140
Indentation, there is pushed into the second through hole, and without external forces, the first connecting tube 300 will not be dropped out from the first notch, the
Two connecting tubes 400 will not drop out in the second notch.
Step S160, one end of locking mechanism 700 is sleeved on the first armouring shell 130, the other end extends to the second armour
On casing 230, after tightening the first nut 740 and the second nut 770,720 and first armouring shell 130 of first sleeve is welded,
Weld the second casing 750 and the second armouring shell 230.
Locking mechanism 700 is put on for convenience, can be after the trouble location of the first connector 100 be cut off or step S140
Before, the first nut 740, first sleeve 720, the first cutting ferrule 730 and connector 710 are first sequentially sleeved in the first armouring shell
On 130, the second nut 770, the second casing 750 and the second cutting ferrule 760 are sequentially sleeved on the second armouring shell 230.Start to hold
During row step S160, whole components of locking mechanism 700 are moved to centre, profit screws up with a wrench the first nut 740 and second
After nut 770, then 720 and first armouring shell 130 of first sleeve is respectively welded, and outside the second casing 750 and the second armouring
Shell 230.
Step S170, by shrinkable sleeve on locking mechanism 700, and carries out pyrocondensation to heat-shrink tube.
It is similar with step S150 and step S160, can be in advance by shrinkable sleeve in the first armouring shell 130 or second
On armouring shell 230, during pending step S170, then heat-shrink tube moved into progress pyrocondensation at locking mechanism 700.
It is noted that it is required for checking insulation and the resistance value of corresponding component among each step and afterwards, really
Protect insulation and resistance is without exception, such as, it is necessary to check the resistance between two cores separated in step S110 and step S120
Value, checks insulation of two cores to armouring shell；For example after step S140, check the first connecting tube 300 and the second connecting tube
400 insulation and resistance etc..
Certainly, if the 4th connector 26 in Fig. 1 breaks down with the 5th connector 28, can be tieed up by same method
Repair, it is very convenient.
Each technical characteristic of embodiment described above can be combined arbitrarily, to make description succinct, not to above-mentioned reality
Apply all possible combination of each technical characteristic in example to be all described, as long as however, the combination of these technical characteristics is not deposited
In contradiction, the scope that this specification is recorded all is considered to be.
Embodiment described above only expresses the several embodiments of the present invention, its description is more specific and detailed, but simultaneously
Cannot therefore it be construed as limiting the scope of the patent.It should be pointed out that come for those of ordinary skill in the art
Say, without departing from the inventive concept of the premise, various modifications and improvements can be made, these belong to the protection of the present invention
Scope.Therefore, the protection domain of patent of the present invention should be determined by the appended claims.
