About solar pv connector, from 1000V to 1500V, The basic performance of solar pv DC power connectors can be divided into three categories: mechanical performance, electrical performance and environmental performance.we will talk about the mechanical performance here. 

1. The mechanical performance is related to the solar connection function, and the pull-out force is an important mechanical performance.about SUNYO solar DC connector ,The pull-out force is >50N,divided into insertion force and pull-out force (pull-out force is also called separation force), and the requirements of the two are inconsistent. There are provisions for the maximum insertion force and the minimum separation force in the relevant standards, which indicates that the insertion force is small from the perspective of use (so there are low insertion force LIF and low separation force LIF) If the separation force is too small, it will affect the contact reliability.The contact terminal is pure copper, the contact resistant of solar MC4 PV connector is less than 5 mΩ,that is good quality.

Using 100% PPO material is also important, more stable and live a long life in the solar power plant with the high quality MC4 solar connector.Another important mechanical property is the mechanical life of the solar connector. In fact, the mechanical life is a kind of durability index, which is called mechanical operation in national extension gb5095. Therefore, one-time insertion and one-time pull-out are a cycle to judge whether the solar connector can normally complete the pv connection function (such as contact resistor value) after the specified insertion and pull-out cycle.

The pulling force and mechanical life of the connector are related to the coating quality (sliding friction number) of the contact structure (positive pressure size) and the arrangement size of the solar contact parts.
