Molding is made by injection molding and stamping of engineering plastics, PVC materials or metal materials to protect the connection points and connect various electrical appliances. It supports the terminal to make it firmly contact, accurate positioning, dust-proof, anti-fouling, moisture proof, insulation protection and so on. When designing the terminals, different materials can be selected according to different needs. Flame retardant or reinforcing materials can be added to the plastic according to the actual situation to achieve the purpose of strengthening or flame retardant, such as adding glass fiber.
Commonly used terminal materials: brass has the characteristics of low cost, good elasticity and good forming quality, but it is easy to be cracked under stress and corrosion. Phosphor bronze has good elasticity and is relatively strong, but has lower conductivity and higher price than brass.
The terminals are commonly plated with tin, tin-lead alloy, silver and gold. The terminals of tin and tin-lead alloys have corrosion resistance and good solder ability. The gold-plated terminals have excellent corrosion resistance and good electrical conductivity. The nickel-plated terminals also have excellent corrosion resistance.Electroplating is to improve conductivity, corrosion resistance and wear resistance, and solder ability. When selecting the terminal, the chain tinned terminal is generally selected.
