What is a rectangular connector housing? What are its main materials and functional characteristics?

A rectangular connector is an electrical connector used to connect different parts of an electronic device to transmit electrical signals and power. It consists of two main parts: a plug and a socket. Between the plug and socket are several pins and slots for connecting wires and cables. The housing of a rectangular connector is the external packaging of the connector, which is an important part of protecting the internal components and ensuring the proper functioning of the connector. Primary Materials The housing of a rectangular connector is usually made of plastic, a commonly used material because of its excellent insulating properties and relative ease of machining into a variety of shapes. Common plastic materials include polyvinyl chloride (PVC), polypropylene (PP), and polystyrene (PS). In addition, some high-end rectangular connector housings may be made of metal, alloy, or composite materials to provide greater strength and durability. Functional features 1.Protection of internal components: The main role of the rectangular connector shell is to protect the internal components from the external environment, such as humidity, dust, corrosion and so on. The sealing and corrosion resistance of the shell is an important consideration.2. Ensure safety: connectors are usually used in high-voltage or high-current environments, so safety is very important. The connector shell must be fireproof, explosion-proof, high temperature resistance and other characteristics to ensure that the connector in a variety of harsh environments can still be safe to operate.3. Convenience and maintenance: rectangular connector shell should be designed with ease of disassembly and maintenance in mind. These features allow users to easily replace the pins, wires and cables and other components, thereby reducing downtime and maintenance costs.4. Convenient assembly: the connector shell design should make the plug and socket can be easily inserted and pulled out, and should ensure that the plug and socket are correctly aligned. In addition, the shell should take into account the ease of installation and fixing.5. Meet the standards: the connector shell should comply with international standards and industry standards to ensure compatibility with other equipment. Common international standards include IEC, UL, CE, and so on.
