Introduction to Backplane Connectors - DIN 41612

DIN 41612 backplane connectors are widely used in many applications due to their high signal density, mechanical robustness and versatility. They are commonly used to connect printed circuit boards (PCBs) and routing signals between board. The use of DIN 41612 connector confers complete signal through between boards up to 65m in length, which can simplify system architecture and reduce costs. This article provides an overview of the different types available and describes the working principle of these connectors.

Types of DIN 41612 Connectors

The current range of DIN 41612 connectors consists of a variety of plug types, and a wide array ofpin counts, shapes and sizes. They can be divided into four major categories: right-angle plugs, vertical plugs, reversable plugs and IDC connections.

Right-angle plugs are designed to connect two boards at a 90 degree angle, usually for low-density signal routing. They are commonly used in applications that require high performance and/or top-mounting. Vertical plugs are designed for signaling and low-density connections between boards. These plugs are typically used for termination and breakout boards. Reversable plugs are designed for high-density connections between boards. They are used in applications that require high signals on all pins and have good environmental protection. IDC connections are used when a semi-permanent connection is required and allow for the connection of more than three boards.

The Working Principle of DIN 41612 Connectors

DIN 41612 connectors use a combination of mechanical and electrical contact techniques to ensure a high level of reliability and electrical performance. The most common contact technique is called a press-fit connection. This technique uses a two-part contact system to connect the plug to the socket. The socket is equipped with a set of spring-loaded pins that are compressed against the plug’s contact pins. This action creates an electrical and mechanical connection between the two components. This type of connection is used in applications that require a high degree of reliability.

The second contact technique employed by DIN 41612 connectors is soldering. This connection technique requires the use of a solder wire to connect the two components together. Solder connections are usually used in applications that require a high level of electrical performance.

The third and final contact technique is an insulated wire wrap connection. This contact technique is ideal for applications that require low levels of electrical interference. This type of connection is easily achieved by passing a wire around two pins and securing the wire with a special electrical clip.

Conclusion

DIN 41612 connectors are widely used in a variety of applications due to their performance, versatility and mechanical robustness. They are commonly used to connect printed circuit boards and route signals between them. DIN 41612 connectors employ a combination of mechanical and electrical contact techniques to ensure a high reliability and performance. These techniques include press-fit connections, soldering, and insulated wire wrap connections.
