Terminal is common in industrial production of connector products during use may be required to stabilize the signal and power transmission to the device, but on the type of Terminal products on the market today thousands, applied materials also vary. Elinker electric, as a professional manufacturer of terminal development, will lead you to explore the secrets behind the production of Terminal.
Conventional materials and characteristics of terminals were summarized as follows:
Selection of Terminal metal
Terminals and connectors, used bus diversion is made of electrolytic copper (H65) as basic material, copper excellent conductivity than silver due to terminal connection of the conductors are copper material, the same material, same expansion coefficient does not have a loose connection problem.
Terminal choice of insulation materials
In order to apply different product requirements, depending on the application different material selection
Thermosetting plastic, 1 EP
With good geometric stability and water absorption is small, compared to tracking index is high. Flame resistance is, in the case of temperature, stable high in thermoplastics, but toughness is bad;
2, glass fibre reinforced polyamide PA-F
Glass fiber and nylon with strong rigidity and hardness, and its temperature is higher compared to non-reinforced nylon. Overvoltage protection so that it also applies to fields.
Reinforced nylon for water absorption less than non-reinforced nylon. Apart from these differences, and other characteristics of these two materials are identical. Provisions in accordance with UL94, flame-retardant grades of fiber reinforced nylon for HB and V0, V0 material dyed black in most cases;
3, thermoplastic polycarbonate PC
Such as high hardness, good toughness and transparency, good dimensional stability, good insulation properties and thermal stability, and so on.
Transparent Polycarbonate cover or identifying material particularly suitable for cover.
Polycarbonates are resistant to mineral acids, gasoline, lipids, carbohydrates, saturated fats and oils corrosion stability.
Polycarbonate caustic solvents, benzene, acetone and ammonia tolerance of less. And stress cracks may form when certain chemical exposure;
4, thermoplastic polyester PBT
PBT has a good geometrical stability, with glass fiber reinforced materials with very high strength and heat resistance. Also with robust flame resistance and excellent electrical properties;
5, thermoplastic polyamide 6.6
Combo terminal insulation shells have very high requirements for quality, the vast majority are made from thermoplastic polyamide 6.6, such processing by injection molding plastics can economically and environmentally, in favour of recycling.
Elinker Electric provide high quality products are widely used in transportation, electronics, electricity, telecommunications and machinery industries, joins has been committed to the high quality of products developed and produced, as a rising star in the field of electrical, Elinker providers in electrical industry needs a series of successful solutions.
