  When using the CATIA module for wire harness data production, the wire harness segment diameter is written into the software as an important parameter. All subsequent clearance checks and motion analysis are based on this value. Therefore, if there is a big difference from the actual situation, it will inevitably lead to the original requirement of meeting the safety gap, and it will be found to have interfered when the vehicle is actually installed, or even cannot be assembled. Konnra wiring harness  engineers provide you with a theoretical calculation method (wire harness standard algorithm) for estimating the outer diameter of automotive wiring harnesses. A wire harness segment is a collection that binds all wires together with tape or other wrapping. Taking into account that the tape is only wound on the wire harness, and the wrapping of casings such as corrugated pipes also needs to determine the outer diameter of the wire harness before selection. Therefore, when calcu...

When we design and manufacture industrial machinery, or consumer equipment, we are faced with a choice, whether to use point-to-point cable "hard connection" to the system, or choose a plug-and-play connector. From a longer-term perspective, of course, the wiring based on connector products is more practical and lower in cost.  Konnra connector  engineers will investigate the reasons behind and introduce you to the fact that connectors are better than hard wiring. Where is it. 1. More time-saving and lower cost General industrial equipment contains a large number of wires between its components and subsystems. When the original equipment manufacturer manufactures the product, it will be assembled at the factory before shipment, then the system is disassembled, disconnected and shipped to the end user, where it is reassembled . If you need to hardwire all cables into the system, then remove and rewire them on site, this will be a very time-consuming task. The pre-assembled con...
