Invention mechanism:
The middle conductor inside high temperature conjunction stick is mostly hollow tube in the prior art, cause the service life of high temperature conjunction stick compared with
Short, failure rate is higher, and main cause is: (1) hollow pipe orifice it is smaller can not carry out in hole clear up or clear up it is not clean, it is different in hole
Object and air accelerate the oxidation and pollution of middle conductor inner hole wall in high temperature conjunction stick use process；(2) hollow tube is also deposited
In the problem that machining accuracy control difficulty is larger, it is unfavorable for industrialized production.
The present invention is improved by the structure to high temperature conjunction stick and solves the above problem, high temperature conjunction stick of the invention
Interior middle conductor is half-sectional tubular structure, and the intensity and rigidity of half-sectional tubular structure are preferably, open to tie relative to hollow tube
The design of structure allows to easily clear up it, will not shorten its service life due to the presence of foreign matter and air；It opens
The design for putting structure facilitates the following process such as welding, reduces difficulty of processing, requirement on machining accuracy is lower, and then significantly mentions
Production efficiency has been risen, production cost is reduced.Therefore high temperature conjunction stick service life of the invention is longer, and difficulty of processing is small, adds
Work required precision is lower.
The longer detector of stable structure, service life can be made using high temperature conjunction stick of the invention, use is existing
When the high temperature conjunction stick of technology prepares detector, the lead of middle conductor and measuring cell is typically all to be welded to connect, in pole
In most cases, the lead of measuring cell and the material of both middle conductors be not identical, and there are biggish for thermal expansion coefficient
Difference, under conditions of high temperature, different degrees of expansion can occur for both the lead of measuring cell and middle conductor, cause to measure
The lead of element and the contact area of middle conductor reduce, or even occur vacantly, i.e., measuring cell is disconnected with pitman, companion
With the generation of high-frequency vibration, measuring cell is contacted with when pitman, when and disconnect, can not normal use, that is, lose use
Function, while after the lead of the measuring cell of different materials and middle conductor assembling, under high temperature and high-frequency vibration, the two can be sent out
Raw unequal power distribution, with the extension of use time, unequal power distribution phenomenon gradually aggravates, and eventually leads to the lead of measuring cell
It is disconnected stick.Thus, the service life of prior art detector as made from high temperature conjunction stick is shorter.
The present invention is adjusted the lead of measuring cell and the connection type of middle conductor, extends the use of detector
In the service life, adjustment mode grips lead using A sections of middle conductor, while lead is goed deep into A sections of parts and is welded with A sections, i.e.,
The lead and middle conductor of measuring cell use clamping+welding connection type, relative to single welding manner, clamp+
The connection type of welding, which can be improved the main reason for stability, durability and reliability of detector, is: (1) clamping+welding
Enable and occur to be bent by a small margin at pad, increases the contact surface of the lead of measuring cell and middle conductor at pad
Product ensure that measuring cell and pitman are in contact condition always, not change with high temperature and high-frequency vibration；(2) clamp+
Welding weakens the lead of the measuring cell of different materials and adaptability to changes occurs for middle conductor, reduces due to stress injustice
A possibility that weighing apparatus causes measuring cell to fall off；(3) clamping+welding increases fixed point, and before increasing clamp structure, fixed point is only
Refer to solder joint, after increasing clamp structure, fixed point further includes the tube wall of half-sectional pipe and the point that lead and solder joint contact, fixed point
Enhance bonding strength；(4) clamping+welding plays certain fixed function to lead, weaken lead in high temperature and
Mobility under high-frequency vibration effect, and then reduce its activity butt welding binding and be constructed of adverse effect, to a certain degree
On alleviate the direct impact of high temperature and high-frequency vibration butt welding point, and then delay detector tired under high/low temperature dilation
Labor improves vibration resistance.
The utility model has the advantages that
(1) the high temperature conjunction stick of the invention containing half-sectional tubulose middle conductor, difficulty of processing is low, and low production cost makes
It is long with the service life；
(2) detector of the invention is suitable for high temperature and high-frequency vibration operating condition, and high temperature resistance and resistance to shock are excellent,
It responds sensitive；
(3) detector of the invention clamps lead by A sections, increase the effective sectional area of its junction into
And increase bonding strength；
(4) detector of the invention, the addition of no third component, fault point is few, good reliability, and application prospect is good.
