Detailed description of the invention
The present invention is further described with detailed description of the invention below in conjunction with the accompanying drawings.
Shown in as shown in Figure 1 to Figure 4, the electrode mounting structure of obliquity sensor of the present invention, including electrode 1 with have
The housing 3 of cavity 2 structure, is provided through the electrode hole 4 of housing 3 on housing 3, and described electrode 1 is inserted into described electrode hole 4
In, and one end of electrode 1 is deep in cavity 2, and the other end of electrode is positioned at outside housing 3, also includes electrode sleeve 5, described electricity
Pole set 5 is enclosed within electrode 1, and is connected by bonding agent 6 solidification between electrode sleeve 5 and electrode 1, and described electrode sleeve 5 is inserted into
In described electrode hole 4, and it is connected by bonding agent 6 solidification between electrode sleeve 5 with electrode hole 4.
The concrete installation process of the electrode mounting structure in the present invention is as follows: the first correct position on electrode 1 is coated
Corresponding bonding agent 6, is then inserted in electrode sleeve 5 on electrode 1 and is adhered on electrode 1 by electrode sleeve 5 by bonding agent 6；It
After again surface at electrode sleeve 5 coat bonding agent 6, then electrode sleeve 5 is inserted in electrode hole 4 together with electrode 1, treats phase
The bonding agent 6 answered solidify bonding after, the installation process of the completeest paired electrode 1.
Due to the electrode mounting structure in the present invention, installed by the solidification connected mode of bonding agent 6, therefore can keep away
Exempt to use electrode 1 direct sintering mounting means in shell structure, and then can avoid owing to sintering process causing electricity
The Oxidation of pole, the most also can improve the installation effectiveness of electrode；And owing to need not be sintered operation, therefore electrode can be first
Installing after carrying out face coat processing, housing carries out electrode after also can first carrying out surface reason or secondary fine processing more again
Install.
It addition, heretofore described bonding agent 6, be for by electrode sleeve 5 respectively with electrode 1 and gluing with housing
The material connect；As long as the bonding agent 6 of above-mentioned adhesive effect can be met in theory.Housing 3 of the present invention is preferably
Ceramic material, the most described bonding agent 6 is preferably ceramet glue, and so-called ceramet glue refers to be specifically designed to pottery and gold
A class bonding agent bonding between genus；So can improve the adhesive effect of bonding agent 6, it is ensured that to firmly installing of electrode 1.And
And, after housing 3 uses ceramic material, the processing to sensor of can being more convenient for；Furthermore, it is contemplated that after housing 3 uses ceramic material
It is not easy to sealing, therefore, as shown in FIG., is further provided with the glass tubing 10 for sealing.
It addition, in order to when electrode sleeve 5 is inserted into electrode hole 4, the installation site of electrode sleeve 5 be played spacing effect,
And then guarantee that the installation site of electrode sleeve 5 is more accurate, described electrode hole 4 can be set to stepped hole structure further.Such as Fig. 3
Shown in Fig. 4, electrode hole 4 includes large aperture section 7 and a small-bore section 8；Described electrode sleeve 5 is inserted into described large aperture section
In 7, and one end of described electrode sleeve 5 is resisted against on the step surface between large aperture section 7 and small-bore section 8.So, installing
Time, it is only necessary to ensure that one end of electrode sleeve 5 abuts to i.e. can ensure that on step surface that electrode sleeve 5 is installed and puts in place, so can enter one
Step improves installation effectiveness.
More specifically, above-mentioned be provided with shoulder hole structure time, large aperture section 7 can use the following two kinds set-up mode:
One, described large aperture section 7 is the one end on electrode hole 4 near cavity 2；The second, described large aperture section 7 is on electrode hole 4
One end away from cavity 2.Wherein, the above-mentioned second way is the situation shown in accompanying drawing 3 and Fig. 4.
It addition, as shwon in Figures 5 and 6, described electrode 1 includes battery core 11 and the first painting arranged in the periphery of battery core 11
Layer 12, the oxide that material is a kind of metal or this kind of metal of described first coating 12；Wherein said metal be gold or
Silver or platinum or rhodium or palladium or caesium.
Owing to the electrode 1 described in the invention described above is used exclusively for the electrode 1 of obliquity sensor, because of in obliquity sensor
Electrode is required higher with the contact relation of electrolyte 9, and in order to improve the sensitivity of electrode 1, it is desirable to occur at sensor
During inclination, corresponding signal can be quickly detected；And in order to realize the quick detection of signal, then need electrode 1 surface and electricity
The contact relation solving liquid 9 can quickly change with the generation tilted.
The electrode 1 being traditionally used for obliquity sensor is all not provided with coating structure, normally only by corresponding alloy material
The most directly using after making battery core 11, therefore the surface of electrode 1 occurs passivation or the feelings of corrosion the most after a long time use
Condition, and the fineness of electrode surface is poor, thus easily adhere to electrolyte, the sensitivity ultimately resulting in traditional electrode 1 is relatively low.
The present invention by arranging the first coating 12 being made up of certain material on the basis of battery core 11, can strengthen further
The resistant to rust of electrode 1 and resist passivation ability, and further by using the sides such as plating, chemical plating, evaporation or ion sputtering
Formula coats the first coating 12, can further improve the surface smoothness of electrode 1, and then electrode 1 can be made by electrolyte surface tension force
Impact less, the sensitivity of electrode 1 can be improved.It addition, also by the Q-value arranging coating reduction electrode；Also can lead to simultaneously
Cross and control the thickness of respective coatings to change the impedance of electrode 1.
It addition, the most also the second coating 13 can be additionally provided with between battery core 11 and the first coating 12, described
The material of the second coating 13 is nickel or cobalt or nickel cobalt (alloy).The above-mentioned purpose arranging the second coating 13 mainly has two, the
One is the defect that can repair battery core 11 surface, to improve effect during coating the first coating 12；Second can be prevented from being coated with
When covering the first coating 12, battery core 11 is caused erosion.
More specifically, above-mentioned be provided with the first coating 12 and the second coating 13 time, when first coating 12 select be not
When gold or alloy platinum material, in order to improve the first coating 12 and combination effect of the second coating 13 further, can be in the first coating 12
With second arrange the 3rd coating 14 between coating 13, the material of described 3rd coating 14 is gold or platinum.Certainly, when above-mentioned first
When the material of coating 12 inherently selects gold or platinum, then can be without arranging the 3rd coating 14.
It addition, generally battery core 11 can select corresponding alloy material according to the difference of the material of sensor housing 3
Material, such as, when housing 3 is ceramic material, be preferably the alloy material of 4J32 with material trademark；And when housing 3 is high borosilicate
During glass, it is preferably the alloy material of 4J29 with material trademark.
Certainly, the coating method of above-mentioned first coating the 12, second coating 13 and the 3rd coating 14 all can use plating, change
The modes such as plating, evaporation or ion sputtering of learning realize, and after the coating coated by the way, any surface finish of its coating
Spend higher, and coat relatively uniform, it can be ensured that the sensitivity of electrode is higher.
