Backplane connectors are an essential part of electronic systems. Their function is to interconnect boards in a system and provide a means for signals to quickly move from board to board. The design and operation of these connectors plays an essential role in their application in a variety of scenarios and this article focuses on discussing the application fields and working principle of a 202283-1 type backplane connector.

Electric Characteristics

The 202283-1 type backplane connector is a double-row, multi-contact, high-density surface-mount connector with a latching feature for quick connection and disconnection. Its full-load current transfer capability is rated at 7 A per contact. It has a rating of up to 10 A per contact when operated at no more than 75°C in current-carrying applications. The electrical characteristics of the connector, such as the contact resistance, insulation resistance, rated current, and the like, meet the requirements of IEC 60512-99-001 standard.

Mechanical Characteristics

The 202283-1 backplane connector is designed to be suitable for a wide range of applications, providing strength and a stable connection. It features a double-row design with up to 8 contacts per row and a low stack height for high-density applications. It is also designed to provide an easy and secure connection, with a latch in each row to ensure a secure connection during use. The locked position is indicated by an audible click. The connector also features a keying system to provide proper mating alignment. The connector has a rated mechanical life up to 500 mating cycles.

Environmental Characteristics

The connector has a temperature range from -55°C to +105°C, making it suitable for a wide range of applications. The connectors are made of materials that meet environmental requirements such as UL 94V-2, UL 94V-0, and UL 94V-1. The connector is also designed to be RoHS compliant, providing compatibility with sustainable products and processes.

Application Fields

The 202283-1 type backplane connector is used in a variety of applications, including: telecommunications, automotive, instrumentation, test and measurement, industrial control, medical electronics, and aerospace. The high electrical, mechanical and environmental characteristics make them ideal for use in high-reliability applications.

Working Principle

The 202283-1 type backplane connector uses a latching mechanism to ensure a secure connection between contacts. The latching feature provides both physical retention and a degree of electrical shielding. The latch also increases the signal integrity of the connection as it decreases susceptibility to vibration and shock. The connector also uses a keying system to ensure the proper mating alignment.

When the connector is mated correctly, the latching feature will click and firmly hold the connector in place. The contacts on each mating pair are then aligned and the electrical connection is established. The connection is then maintained until the latching feature is released and the connector can be disconnected.

Conclusion

The 202283-1 type backplane connector is an ideal choice for a wide range of applications due to its high electrical, mechanical and environmental characteristics. Its latching feature and keying system ensure a secure and reliable connection in high-reliability applications. Its design also provides a low stack height for high-density applications. With its wide range of application fields and easy and reliable working principle, the 202283-1 type backplane connector is well-suited for a variety of applications.
