To choose the right cable ties for wiring harnesses, consider the material, length, width, tensile strength, and environmental conditions. For general use, standard nylon ties are a good choice, but for heavier loads or harsh environments, stainless steel or UV-resistant ties are recommended. Measure the bundle diameter to ensure proper fit and select a tie with adequate tensile strength to support the weight and stress of the wiring harness.

It is connected to all functions in the vehicle via power and data. The dimensionally stable, easy-to-install and space-saving wiring harnesses are also optimized with regard to the vehicle type: whether low-cost car or premium brand vehicle – they all have the wiring system in common.

Proper crimping involves selecting the right crimp terminal and crimping tool, stripping the wire insulation, inserting the wire into the terminal, and using the tool to create a secure connection. A ratcheting crimping tool ensures a uniform and stable crimp.

Reliability analysis of power and signal connecting cables involves evaluating their ability to consistently perform their intended function over a specific period and under defined conditions. This analysis is crucial for ensuring stable signal transmission and reliable power supply, impacting various applications like military equipment and power grids.

The automotive wiring harness manufacturing industry has been the largest user of ultrasonic welding since the late 1980s, primarily using the technology for wire splicing. However, new applications of the technology are being used as part of future processes that will ultimately provide automakers with solutions to many of the shortcomings of today’s electric vehicle technology. This article mainly introduces the ultrasonic welding of automobile wiring harness busbars and busbars.

Withstand voltage testing, also known as a Hipot test or dielectric withstand test, is crucial for evaluating the durability of connecting cables by assessing their ability to withstand high voltage without failing. This test ensures the cable’s insulation can handle the maximum voltage it might encounter during its lifetime, preventing insulation breakdown and ensuring reliable operation.

A broken Electronic Parking Brake (EPB) connection harness can cause issues with the EPB system, potentially preventing it from engaging or disengaging properly. Common symptoms include the EPB not releasing, a malfunction indicator lamp (MIL) illuminating, and service messages displayed. The EPB system relies on electronic signals to control the brake pads, so a broken harness can disrupt these signals.

Quality management in wire harness assembly involves a multi-faceted approach, including rigorous quality control measures at each stage of the process, from incoming material inspection to final testing and adherence to industry standards like IPC/WHMA-A-620. This includes implementing a formal quality management system, ensuring proper training and experience of personnel, and establishing robust maintenance programs for equipment.

Failure in crimped connections can stem from improper crimping techniques, tool damage, or material degradation, leading to issues like poor contact, insulation breakdown, or weak fixation. These failures can result in short circuits, open circuits, or even complete connection failure. Visual inspection and testing methods like ultrasonic transmission or tensile testing can help identify and prevent these issues.
