Basic Performance And Characteristics Of Bimetallic Terminal Block Connectors

The basic performance of bimetallic lugs can be divided into three categories: mechanical performance, electrical performance and environmental performance.

1. Mechanical performance In terms of connection function, bi metal cable lug plugging and unplugging force is an important mechanical performance. The plugging and unplugging force is divided into insertion force and extraction force (extraction force is also called separation force), and the requirements of the two are different. In the relevant bi metal lugs connectors standard, there are provisions for maximum insertion force and minimum separation force, which shows that from the perspective of use, the insertion force should be small (thus there are structures of low insertion force LIF and no insertion force ZIF), and if the separation force is too small, it will affect the reliability of bi metallic cable lugs contact.

Another important mechanical performance is the mechanical life of bimetal cable lug.Mechanical life is actually a bimetal terminal lug durability indicator, which is called mechanical operation in the national standard GB5095. bimetallic lugs price is based on one insertion and one unplugging as a cycle,and uses whether bimetallic lugs price list can normally complete its connection function (such as contact resistance value) after the specified plug-in cycle as the basis for judgment.

The insertion and extraction force and mechanical life of cable lug bimetal are related to the contact structure (positive pressure), the quality of the contact coating (sliding friction coefficient) and the contact arrangement dimensional accuracy (alignment).
