Rectangular Connectors - Housings

Rectangular connectors are commonly used in numerous applications, ranging from computer, control, and industrial automation systems, to medical and military equipment. Housings are part of the rectangular connector system and provide features such as strain relief and environmental seals that protect the electrical and optical contacts. They are designed to keep the contacts in place, reduce electromagnetic and radio frequency interference, and they also provide durable and flexible designs that are both user-friendly and space-saving.

Types of Housings

Housings can be categorized into three main types: injection molded plastic housings, die-cast metal housings, and housings made from thermoplastic elastomer or rubber materials. Injection molded plastic housings are produced from engineering-grade, impact-resistant nylon and polyester for strong and secure connection. Die-cast metal housings are made from aluminum or zinc alloys and provide increased protection against EMC interferences. Housings made from thermoplastic elastomer or rubber materials are highly resistant to environmental factors.

Application Fields and Working Principle

Rectangular housings are used in numerous application fields which require a secure, durable, and reliable connection. Common application fields include automation, computer, control, medical, automotive, and military equipment. According to their working principle, housings can be divided into four types: inserts, clamps, split, and non-split housings. Inserts are inserted into the mating cavity of the device and require two directions to work. Clamps attach the cable to the female housing connector. Split housings are composed of two parts, which are held together by screws. Non-split housings are also two-piece designs, but they are held together by clips or other types of attachments.

Performance and Standardization

Rectangular connectors employ contact and positioning mechanisms to ensure electrical continuity and reliability. Contacts are usually assembled into housings, which put them into the proper position. In some cases, pins, bolts, and clamps are used in combination to hold each contact in place. Moreover, some housings have strain reliefs that provide protection against mechanical and environmental strain, as well as against abrasion, torsion, vibration, and extreme temperatures.

Rectangular connectors are standardized by various international standards like IEC 61076-2-101. These standards provide a common reference of specifications and tests used to ensure compatibility between different parties and to ensure the reliable operation of the electrical connectors. Furthermore, these standards also describe and classify the different types of connectors, providing key information such as size, design, material, etc.

Conclusion

In conclusion, rectangular connectors are widely used in different application fields utilizing housings, which are made from various materials. Housings protect the contacts from environmental factors, reduce electromagnetic and radio frequency interference, and provide durable and flexible designs. All of these factors make rectangular connectors well-known in the market and perfect choice for those looking for a secure and reliable connection.
