Terminal blocks are common in the industrial production of connector products, in the course of a stable signal can be transmitted with the current to the desired device, but there are thousands of products on the market on the terminal type, its application materials are not same. Terminals on research and development as a professional manufacturer, will lead you to explore the circumstances behind the production of the terminals. Terminal conventional optical fiber cable production materials and characteristics are summarized as follows:
Terminals and connectors, terminal block bus diversion body is used copper (H65) as a base material, excellent conductivity of copper silver public inferior, since the wires are connected to terminals copper material, the same The material does not produce the same coefficient of expansion loose connection problems. To apply a different product requirements shall choose different materials depending on the application a thermosetting plastic EP has good geometric stability, water is small, compared to the tracking index. Flame retardant very, at elevated temperatures, superior grade thermoplastics stable, but poor toughness;
2, terminal block of glass fiber reinforced nylon PA-F Nylon fiber glass has a strong rigidity and hardness at higher temperatures compared to the use of non-reinforced nylon. It also applies to the hdmi splitter over-voltage protection fields. Reinforced nylon to absorb less water than non-reinforced nylon. Except for the above difference, the same as other characteristics of the two materials. In accordance with UL94, the flame retardant nylon fiber reinforced grade HB to V0, where V0 dyed black color type material in most cases; 3, thermoplastic polycarbonates PC
Such as high hardness, impact toughness, transparency, dimensional stability, good insulation properties and good thermal stability. Particularly suitable for transparent polycarbonate cover or logo resistant polycarbonate material stability mineral acid, saturated fat carbohydrates, petrol, fats and oils erosion. Polycarbonate solvent, benzene = lye, acetone 12 port patch panel and ammonia tolerance to be worse. May form the contact stresses and cracks certain chemical reagents; 4, PB PBT thermoplastic polyester having a good geometric stability, using a material having high strength and heat resistance of glass fiber reinforced. But also has excellent flame resistance and reliability of the electrical resistance 5, the quality of the combined thermoplastic terminals Nylon 6.6 has a high dielectric housing requirements, most made by thermoplastic nylon 6.6, the plastic can economically by injection molding processing, and environmentally friendly, beneficial recycling.
