Rectangular connectors are a useful choice for devices and applications requiring more flexibility and higher power delivery than standardround connectors. Specifically, arrays, edge type, mezzanine (board to board) connectors are all types of rectangular connectors. This article will discuss the application field and working principle of these connectors.

Application Field of Rectangular Connectors - Arrays, Edge Type, Mezzanine (Board to Board)

Rectangular connectors provide an effective solution for situations that require a more reliable and secured connection. Generally, they are used in devices and applications such as industrial equipment, medical devices, consumer electronics, automotive electronics, marine electronics, and telecommunications. Depending on the application, different types of rectangular connectors provide different benefits. For example, array connectors are commonly used in industrial equipment where ruggedness, vibration resistance, and harsh environmental conditions are a consideration. Edge type connectors are popular for ultra-slim design of PC motherboards, offer multiple mechanisms for securely connecting backplanes and boards together. Mezzanine (board to board) connectors are well-suited for capacity-constrained applications where space and size are the main consideration.

Working Principle of Rectangular Connectors - Arrays, Edge Type, Mezzanine (Board to Board)

The working principle of the different rectangular connectors, such as arrays, edge type, and mezzanine (board to board) connectors, is based on the same basic principles of electrical connectivity. The connectors feature diverse contact systems with different configurations. Array connectors are typically composed of two circuit boards with rows of metal contacts which are used to make electrical connections. Edge type connectors come in a variety of configurations including low profile, right angle, and curved designs. These connectors feature different patterns and number of contacts depending on the configuration and may use different metals for the contacts. Mezzanine (board to board) connectors are designed to conserve board real estate and reduce the number of physical connections needed in space-constrained applications. They feature multiple rows of staggered interconnects, each accommodating both signal and power contacts, with different mating configurations.

Generally, this type of connectors also provide improved operating temperatures, dynamic performance, and signal integrity. They are also designed to provide relatively low insertion and withdrawal force while also providing the necessary security against accidental detachment. Additionally, the use of different metals on the contacts allows for improved electrical and thermal performance.

Conclusion

Rectangular connectors can provide several benefits in devices and applications requiring more flexibility and higher power delivery than standard round connectors. Specifically, array, edge type, mezzanine (board to board) connectors are popular choices for industrial, consumer, medical, automotive, marine, and telecommunications applications. The working principle of the different types of connectors is based on the same basic principles of electrical connectivity, providing improved operating temperatures, dynamic performance, and signal integrity. With these features, rectangular connectors are an effective solution for various applications.
