Rectangular Connectors - Housings

Connectors are components that mechanically and electrically link two or more circuits. Rectangular connectors, also known as box connectors, are commonly used in electronic circuits. Housings, which are the backbone of the connector, provide the structure that holds and supports the contacts.

Types of Housings

Housings can be divided into two main categories: injection-molded and metal. Injection-molded housings are made from thermoplastic materials, such as polyamide or polyester. These materials are injected into a mold and the resulting part has an excellent resistance to mechanical stress and weight. Metal housings are made of machined aluminum, stainless steel, or brass. Compared to injection-molded housings, metal housings offer greater mechanical strength and better shielding properties.

Application Field and Working Principle

Rectangular connectors are widely used in many applications, including automotive, medical, aerospace, and manufacturing. In automotive electronics, they are used to connect sensing devices and other components to control systems. In medical electronics, they are used to connect medical devices to each other and to a central control unit. In the aerospace industry, they are used to connect sensing and control devices to various systems. In the manufacturing industry, they are used to connect process equipment components.

The working principle of a rectangular connector is fairly simple: two or more contacts are mechanically and electrically connected to each other when the connector is plugged in. The contacts are typically made of metal and are seated in the body of the housing. When the connector is mated, the contacts in each housing are connected, forming an electrical connection. This connection can then be used to transfer data, power, or signals between the two components that the connector is connecting.

Conclusion

Rectangular connectors are a versatile and reliable type of connector for a variety of applications. By providing a mechanical and electrical connection between two or more circuits, they enable the transfer of data, power, and signals. Housings form the backbone of the connector, providing structure and mechanical strength. Rectangular connectors come in two basic types: injection-molded and metal. They can be used in a wide variety of applications, including automotive, medical, aerospace, and manufacturing.
