Rectangular Connectors - Housings

The rectangular connectors field includes a wide variety of components, and one of the most important is an integral part of the assembled connectors, the housing. Virtually all commercial connectors use a molded housing to provide the contacts with mechanical and environmental protection.

Overview

Housings are designed to be durable and reliable, and feature various types of mounting methods. Depending on the application and configuration needed, these can range from snap in, screw, and insertion / extraction configurations. Common materials of headers and housings include polyamide, epoxy, and die-cast zinc. Housings come in three forms: Closed-end, plug and receptacle, and clamshell housings. For industrial and heavy-duty connectors, metal housings are also employed.

Connectors and Hardware

Connector hardware is typically used to secure the contacts, housings and other connectors to one another. Common hardware includes screws, nuts and springs. Some connectors include specialized types of hardware, such as bayonet coupling, for fastening and secure connections.

Materials Used for Housings

Polyamide (nylon) is the most common material used for housings due to its low cost and electrical properties. It is also easy to form into the required shape, and can be molded to form a strong connection with other connector components. Nylon housings offer RFI and EMI protection.

Epoxy is another popular housing material as it is durable and able to withstand high temperatures. It is also resistant to impact, and can be used in a wide variety of applications. Epoxy offers superior environmental protection and is suitable for use in harsh working conditions.

Metal housings are used in industrial and heavy-duty applications, as metal offers better electrical, physical and chemical protection compared to polyamide and epoxy. Metal housings are available in stainless steel, aluminum, and brass, each with their own unique characteristics.
