The mechanical performance of the connector is crucial in terms of its connection function. The FUTURE BUS connector is customized and the insertion and extraction force is an important mechanical performance. The insertion and extraction forces are divided into insertion force and extraction force (also known as separation force), and their requirements are different. In relevant standards, there are provisions for larger insertion force and smaller separation force, which indicates that from a usage perspective, when customizing FUSURE BUS connectors, the insertion force should be small (resulting in structures with low insertion force LIF and no insertion force ZIF), and if the separation force is too small, it will affect the reliability of contact. Therefore, when customizing FUSURE BUS connectors, the insertion force should be small. Another important mechanical property is the mechanical life of the connector. Mechanical life is actually a durability indicator, referred to as mechanical operation in the national standard GB5095. It takes one insertion and one extraction as a cycle, and takes whether the connector can normally complete its connection function (such as contact resistance value) after the specified insertion and extraction cycle as the judgment basis. The insertion and withdrawal force and mechanical life of the connector are related to the contact structure (positive pressure), the coating quality of the contact part (Sliding friction coefficient) and the dimensional accuracy (alignment) of the contact arrangement.
