Rectangular Connectors - Housings

Rectangular connectors are an essential component in modern electronics and communication systems. Applications for these components range from consumer goods, business equipment and industrial systems, to government and military applications. Rectangular connectors come in various housing types and these differences in housing materials and shapes affect cost, performance, as well as the application suitable for use in a particular environment. This article will explain the common housing types for rectangular connectors and discuss the working principles behind these products.

Housing Types for Rectangular Connectors

Rectangular connectors come in many housing types, the two most common being plastic housings and metal housings. Plastic housings are available in two main categories, thermoplastic and thermoset. Thermoplastic housings are lightweight, inexpensive, and impact resistant, and usually come in a range of standard colors, making them a good choice for consumer products and low-cost applications. Thermoset housings offer higher strength and durability, low porosity, and resistance to heat, humidity, and solvents, making them suitable for industrial and military applications. Meanwhile, metal housings are able to provide superior performance—greater durability, higher strength, better vibration protection, and shock resistance. These housings are mainly used in high-power communication devices and equipment, often for military applications.

Working Principles of Rectangular Connectors

The working principle of rectangular connectors is relatively simple. A rectangular-shaped metal contact is attached to a plastic or metal housing. The housing is designed to protect the contact from abrasion and impact, while ensuring that it can securely mate with a similar rectangular contact. The contacts in rectangular connectors are usually made from high quality metallurgical material and gold-plated for improved conductivity, corrosion resistance, and long service life. The housing consists of two halves, which are connected together by means of a locking mechanism. This connection ensures that the contacts in the housing are securely locked together, while allowing the user to easily change out the contact if needed.

Applications of Rectangular Connectors

Due to their wide range of housing types and characteristics, rectangular connectors are used in a variety of applications, ranging from everyday consumer devices to complex military systems. Some of the most common applications for rectangular connectors include automotive electronics, medical equipment, test and measurement systems, military systems, and computer systems. Rectangular connectors, with their improved performance, durability, and cost, have become the industry standard for a variety of different applications.

Conclusion

Rectangular connectors are ubiquitous in modern electrical and communication systems, and their housings are essential to the performance and reliability of these components. The two main types of housing for rectangular connectors are plastic and metal, with each offering their own unique characteristics that make them suitable for different applications. The working principle of rectangular connectors is relatively simple, and their applications range from consumer goods to military systems. With their improved performance, durability, and cost, rectangular connectors are the industry standard for a variety of different applications.
