How to choose insulation material for connector design?

Excellent designers in the design of the electrical properties of each material, mechanical and physical properties are well known, and then according to the actual use of the connector scenarios for targeted selection, so as to enhance the service life and reliability of the product, today listen to the Huicheng Yuan Electronic Technology Co., Ltd. R & D engineers to give you an introduction to our conventional RF coaxial connectors in the design of the following types of materials used in the Insulation. First, PTFE (polytetrafluoroethylene) material. 1, with excellent thermal stability (-200 ° C - 250 ° C) and flame retardant high temperature resistance, in the use of the process is not easy to deform. 2, anti-static, anti-adhesive material, good electrical properties, almost independent of frequency and temperature. The coefficient of elasticity is low, so it is commonly used as insulator material.3, Mainly used in through-wall installation . Cable assembly, panel mounting and other non-patch connector above the majority of two, PEEK material 1, PEEK is a locally crystalline material with strong tensile strength, excellent thermal stability, high melting point (334 ° C), good chemical inertia (except sulfuric acid). Strong corrosion resistance, high irradiation resistance. 2, with self-extinguishing, even without any flame retardant, can reach UL standard 94V-0 level. 3, with good electrical insulation properties, and maintained to a very high temperature range. Its dielectric loss is also small at high frequencies. This PEEK is routinely used in SMP patch connectors 2.92 connectors 3.5mm connectors and other patch field and high-frequency connector field mostly
