Automotive wiring harness connector types, connectors, connector products factory Chong Xu Song (view) from Dongguan Shijie Song Chong-wook electronic products factory provided. Dongguan Shijie Song Chong-wook Electronic Products Factory (chuangxs.1688.com) Guangdong Dongguan, connectors leaders, over the years, the company is implementing scientific management, innovation and development, the principle of honesty and trustworthiness, and satisfy customer needs. Song Chong-wook in electronic products factory leadership with the staff warmly welcome all inquiries negotiations to create electronic products factory Chong Xu Song a better future. The basic properties of the connector can be divided into three categories: the mechanical properties, electrical properties, and environmental performance. Another important mechanical properties are the mechanical life of the connector. Mechanical life is actually a durability (durability) indicators in the GB GB5095 called it a mechanical operation. It is first inserted and a pull out as one cycle to cycle after a predetermined mating connector can normally complete its connection function (such as a contact resistance value) as the basis for evaluation. 1. Mechanical properties on connectivity, the insertion force is important to the mechanical properties. Insertion force into the insertion and extraction force (pull force known as the separation force), both requirements are different. Insertion force maximum and minimum predetermined separation force the electronic component connector in the relevant standard, which shows that, using the angle of view, the insertion force to be small (and thus has a low insertion force and no insertion force ZIF LIF structure), and the separation force If too small, it will affect the contact reliability. Connector insertion force and mechanical life and the contact structure (positive pressure size) contacting the coating quality parts (sliding friction coefficient) and contact arrangement dimensional accuracy (degree of alignment) related. 2. The main electrical connector electrical performance properties including contact resistance, insulation resistance and dielectric strength. Type of connector products division, although some confusion connectors, but from a technical point of view automotive wiring harness connector types, connector products division only two basic categories ways: ① Press shape structure: circular and rectangular (cross-section); ② according to operating frequency: low frequency and high frequency (3MHz is bounded to). According to the above division, coaxial connectors belong to the circular, printed circuit connectors belong rectangular (Historically, the printed circuit connector is indeed separated out from the rectangular connector sui generis), while the currently popular a rectangular cross-section is a trapezoid connector, similar to a rectangle. 3MHz for demarcation to the low and high-frequency radio wave frequency division is basically the same. As for the other end-use, installation, special structure, special properties can also be divided into many different types, and often appear in publications and promotional materials manufacturer, but generally only to highlight certain characteristics and uses, the basic classification is still does not exceed the above-mentioned principle of classification.
