Description
Technical field
The present invention relates to conducting ring technical fields, especially a kind of conducting ring seal tightness test room test method.
Background technique
Conducting ring is a kind of typical sliding Electical connector, is passed for realizing medium between two relative rotation mechanisms
Defeated precision apparatus.It is mainly made of slip ring and brush filament two large divisions, is carried out by the principle that the overlap joint of brush filament and slip ring rolls
Signal transmission, wherein brush filament and slip ring are the important performance indicators of conducting ring in the resistance that contact site generates.In adverse circumstances
The lower conducting ring used, needs to be sealed design, to prevent the entrance of fifth wheel, to guarantee that conducting ring contact electric resistance conforms to
It asks.
The Packed conducting ring product of domestic conducting ring professional production producer, but really sealing effect can not be surveyed
Examination, is guess value, has no theoretical foundation.It can be convenient therefore, it is necessary to develop one kind out and accurately whether accord with sealing effect
Close the test method that prescribed requirement is illustrated.
Summary of the invention
In place of making up the deficiencies in the prior art, a kind of design rationally, using easy and energy is provided
By the method for the accurate and visual laboratory's testing conductive ring sealing effect reflected of sealing effect.
The purpose of the present invention is what is realized by following technological means:
A kind of conducting ring seal tightness test room test method, it is characterised in that: the following steps are included:
(1) prepares
Prepare conducting ring model machine to remove the outer cover in model machine, protecting block after complete machine cleaning, humidity sensitive resistance is distinguished
It is fixed in brush filament with wiring, outer cover is installed again, and prepare one after humidity sensitive resistance lead is drawn together with brush wire
Portable contact resistance tester, the portable contact resistance tester is for testing humidity sensitive resistance in subsequent steps
Variable quantity；
(2) is tested
After humidity sensitive resistance lead in conducting ring is connect with portable contact resistance tester, conducting ring is put into
High/low-temperature impact case carries out humidity referring to the experimental condition of steady state damp heat test procedure stipulation in national military standard GJB 1217A-2009
Test；
(3) experimental data processing
By the humidity resistance change data preparation of test, the comparison statistical chart of contact resistance variation amount and humidity is formed,
According to humidity sensitive resistance characteristic, the theoretical value of conducting ring interior humidity can be found from figure；If at the appointed time, real
Border humidity is no more than the humidity theoretical value of goal-setting, then it represents that sealing effect is good, meets the requirements, otherwise, it means that sealing
It is unqualified.
Moreover, step (2) in the national military standard GJB 1217A-2009 steady state damp heat test procedure stipulation experimental condition
Are as follows: temperature :+38 DEG C~+42 DEG C；Humidity: 95%；Time: 96h.
The advantages and positive effects of the present invention are:
Achievement mentality of designing of the present invention is novel, has novelty.Humidity thermistor is fixed in conducting ring by this method
Portion assesses the sealing effect of conducting ring by the method for detecting conducting ring interior contact resistance variations, to solve conducting ring
The problem that leakproofness is unable to test has promotional value.
Conducting ring leakproofness is tested using the method for the present invention, can be obtained by data information accurately as a result,
To help staff fast and accurately to judge whether conducting ring leakproofness is qualified, is conducive to the qualification rate for improving product, keeps away
Exempt from substandard product to come into the market.
This test method using it is simple, be easy to grasp and test result is intuitively accurate, can accelerate to examine using the method for the present invention
The speed of survey improves working efficiency, ensures product quality.
Detailed description of the invention
Fig. 1 is humidity sensitive resistance installation diagram；
Fig. 2 is humidity sensitive resistance characteristic figure；
Fig. 3 is test result figure.
In figure: 1 is slip ring；2 be brush filament and humidity sensitive resistance.
Specific embodiment
With reference to the accompanying drawing in detail narration the embodiment of the present invention, it should be noted that the present embodiment be it is narrative, no
It is restrictive, this does not limit the scope of protection of the present invention.
A kind of conducting ring seal tightness test room test method, comprising the following steps:
(1) prepares
Prepare conducting ring model machine to remove the outer cover in model machine, protecting block after complete machine cleaning, humidity sensitive resistance is distinguished
It is fixed in brush filament with wiring, as shown in Figure 1.Humidity sensitive resistance lead installs outer cover again after drawing together with brush wire, and
Prepare a portable contact resistance tester, the portable contact resistance tester is for testing humidity in subsequent steps
Sensitive resistance variable quantity.
(2) is tested
After humidity sensitive resistance lead in conducting ring is connect with portable contact resistance tester, conducting ring is put into
High/low-temperature impact case carries out humidity referring to the experimental condition of steady state damp heat test procedure stipulation in national military standard GJB 1217A-2009
Test, experimental condition are as follows: temperature :+38 DEG C~+42 DEG C；Humidity: 95%；Time: 96h.
(3) experimental data processing
By the humidity resistance change data preparation of test, the comparison statistical chart of contact resistance variation amount and humidity is formed,
As shown in figure 3, according to humidity sensitive resistance characteristic, such as Fig. 2 can find the theoretical value of conducting ring interior humidity from figure.Such as
At the appointed time, the humidity that actual humidity is no more than goal-setting requires numerical value (humidity theoretical value) to fruit, then it represents that sealing effect
Fruit is good, meets the requirements.Otherwise, it means that sealing is unqualified.
Such as in Fig. 3, humidity value is 30% in conducting ring when testing initial, and after test in 48 hours, humidity is still
30%, no more than the 60% humidity requirement of goal-setting, illustrate that sealing effect is good.Continue to be tested to 72 hours, humidity is still
30%, illustrate that sealing effect is good, meets the requirements.
