What are the types of heavy duty connector housings? What are their material requirements characteristics?

A heavy-duty connector is a type of connector used to connect high-power circuits and is often used in areas such as industrial and automotive applications. The shell material of heavy-duty connectors has an important impact on its performance and service life, and different application scenarios require different shell materials. The following are the common types of heavy-duty connector housings and their material requirements and characteristics. 1. Metal shell Metal shell is the most commonly used shell for heavy-duty connectors, usually made of aluminum alloy, magnesium alloy, copper, steel and other materials. The metal shell has high strength, good heat dissipation and good anti-corrosion performance, can withstand large mechanical shock and vibration, and is suitable for high temperature, high humidity and high corrosion environment. However, the weight of the metal shell is large, and it is vulnerable to electromagnetic interference. 2. Plastic shell Plastic shell is a lightweight heavy-duty connector shell, usually made of high-strength engineering plastics such as polyamide, polypropylene and polycarbonate. The plastic shell has good insulation performance and corrosion resistance, which can meet the requirements of most industrial and automotive application scenarios. In addition, the plastic shell can also be manufactured by adopting an injection molding process, so that the production cost is lower, and the plastic shell has better design flexibility and plasticity. 3. Fiberglass housing Fiberglass housing is a heavy-duty connector housing with high strength, high temperature resistance and corrosion resistance, which is usually made of fiberglass reinforced polyamide and other materials. Glass fiber shell has good heat resistance and fire resistance, and can withstand harsh environments such as high temperature and high pressure. However, compared with other shell materials, glass fiber shell is more difficult to process and more expensive. 4. Mixed material shell Mixed material shell is a kind of composite material which combines metal, plastic, glass fiber and other materials. It has the advantages and characteristics of various materials and can adapt to various complex application environments.
