Mobile WebSiteIn the current domestic wire harness processing market under the pressure, such as tin-like composite steel belt in a large number of wiring harness factory is still used, even including some large wire harness manufacturers. The quality of the wiring harness has strict requirements of the user, the need for the most basic of the raw material to be controlled to ensure the long-term service life of the wiring harness.
Polyethylene should have excellent rheological properties, and good polyethylene has a uniform and stable melt index. Suitable for different beam diameter, to achieve a certain extrusion speed. Stable extrusion flow, to ensure that the product geometry, the appearance of the integrity, that is, the product will not appear rough surface, wrinkles, bamboo, blistering, local thinning. In order to accommodate large-scale production, the stability of the batch performance of the jacket material as a wire harness is also critical, and the frequent adjustment of the extrusion process due to the instability between batches is bound to affect the final performance of the wire harness. Poor quality of the jacket material, especially the recovery of the sheathing material within each batch and between the batch and the batch is difficult to ensure its performance and stability, and therefore in the wiring harness when the wiring harness jacket, the need to constantly adjust the process Parameter, which will ultimately affect the stability of the harness quality.
The idle process is set to the lowest priority in all processes and is executed when other processes are idle, and the effect is to make the indicator light flash to display the load condition. The results of modal analysis play a guiding role in the selection of materials and the optimization of geometric dimensions. Finally, the quality of the bearing platform is reduced and the layout is more rationalized. The dynamic characteristics of the whole bearing platform are also improved with the adjustment of the rib layout and the reasonable distribution of the quality. The frequency of the first six orders of the platform is above, which avoids the frequency of the luper excitation signal and the dynamic performance of the model Our requirements can provide a good bearing environment for the test.
To detect the connection information of the selected number of harnesses, set the function selector switch to the detection input and run the test station. If the test results are qualified, the instrument prompts qualified; if the test result is unqualified, then the error, and in the unqualified wire position and error type display area shows the wrong terminal location and error type, where the error code that short circuit, , With a decimal point of the number of on-resistance is too large, the figure is the measured resistance value. The type of error detected is.
There is also an important feature of the skin effect, which is a phenomenon in which the current flowing through the circular conductor is diverted to the surface of the conductor at a higher frequency, which makes the conductor almost as if it becomes a hollow Tube in general, that is, this effect, making coaxial wiring harness possible. This effect increases the surface resistance of the conductor at high frequencies and causes phase shift.
The wiring harness processing and harness automatic test system platform is based on the cable tester can also be other types of similar tester-based, through the design of special test adapter to achieve system testing. The tester consists of a host and a number of test expansion modules, each test module has a core test interface, a total of high-speed relay arranged in a matrix, a host can drive the test expansion module.
