The big difficult problem that checks crimp connector was solved by NASA

What Com) contradicts is, although press successional knot,be naked eye completely visible, detect very hard however; A lot of elements can cause an error, the crimp force that did not bring to bear on equably for example, circuitry is not right neat, pressure is too great (the likelihood brings about solid state or standard circuitry appears tiny crack) , pressure is too little (can bring about because of vibration join intermittence normally) ... etc. Be solved in order to tear open or be to help a test (the means such as Pull-to-failure Test) will detect the quality that crimp links is not appropriate, because need to destroy concatenate itself; Sample checks randomly or tearing open solution to be able to be used only is set of test and verify of in order to. So, how should use do not provide ruinous method to check these connecting again quickly? They are important link interface of the system, reliability is very important. To solve this problem, american aerospace total arrange (the program that the Langley research center with subordinate NASA) offers is to use sex of a kind of real time to exceed sound wave equipment (following graph) , with advanced signal the analysis judges a link to whether pass a test; This system (can provide authorization now) be convey a sound wave when the crimp that make is concatenate go in. The tool that NASA developed quality of connector of crimp of a kind of test (picture origin: The data that NASA) provides according to NASA, rise as the pressure that bring to bear on and crimp connects end points is circling circuit to be out of shape, the supersonic wave weaveform that crosses a link also can follow a change; This system can analyse the change of signal, include the content such as amplitude and frequency, with as judgement circuitry and concatenate terminal electric the hand that links quality with machinery (following graph) . The quality that can judge crimp easily to link with weaveform of supersonic wave signal (picture origin: NASA)NASA points out, different crimp links quality problem, control relay path inadequacy, route for example omit, circuit inserts part of not complete, insulation to fall off, and circuit norms is incorrect wait, can be come out by the test with this kind of method. This kind of nicety and concatenate test method uses apparent and effective crimp easily not merely, and be can undertake in the concatenate process that make, either when make after finishing, just check; If press successional knot to have any problems, handlers can suspend an action immediately before must be solved with providing ruinous means more, find out a mistake. If connect,pass a test, circuit can arrive repeatedly instantly on end points, absolve process cabled yarn subsequently (it is to be in giant wiring harness normally) need. Method of this supersonic wave analysis is not a basis single number or it is single group number, check according to define with tired computation however whether pass a barrier; E.g. , among them a kind of method is measure in crimp process bring to bear on to connect at crimp one or more bit more specific pressure, this is the minor part in evaluating crimp course actually, and rather than sees through supersonic wave weaveform crimp is concatenate and actual complete degree. The author guesses, collect more data when us, capable to make measure smaller, cost is lower measure equipment (exceed sound wave to send and receive for example implement) , and development intelligence is algorithmic, ecbolic more tests program this kind. Below a lot of circumstances, measuring single number only may be insufficient, we also have the powerful tool that more can use now. Had you once made this kind of precision but check simply? Is what test case perhaps having you does the hope also have what can you provide support like this kind of method? Greeting discussion! CNC Milling CNC Machining
