Backplane Connectors - Specialized

The MMD25-0141R1 is a backplane connector designed and manufactured by Molex Corporation. A backplane is an interconnected structure of printed circuit boards that are used to support and connect multiple components, such as a CPU, memory chips, and communication interfaces. The MMD25-0141R1 backplane connector is a specialized type of connector that is specifically designed for use in applications where the installation environment is especially demanding.

Applications

The MMD25-0141R1 backplane connector is well-suited for a variety of applications, including high-performance computing, telecommunications, audio equipment, mobile information technology, machine vision, computer-to-computer communication, industrial automation, and military equipment. The connector is designed to provide reliable power and signal paths in high-vibration applications, such as in military helicopters and jet fighters as well as other airborne and deep-water applications. The connector is also an ideal choice for cold-weather applications, because its sealed design ensures that the connection never loses its integrity.

Design

The MMD25-0141R1 backplane connector is designed to provide the highest levels of reliability and performance. The connector is made from a high-grade thermoplastic material that is resistant to corrosion, shock, vibration, and extreme temperatures. The connectors are color-coded for easy identification and installation, and the individual contacts are divided into two groups to reduce circuit trace lengths and improve signal integrity. The patented Keying System of the MMD25-0141R1 backplane connector ensures proper mating and creates a secure connection in areas that require reliable data transmission.

Working Principle

The MMD25-0141R1 backplane connector is designed to be used with standard backplane trays. The connector is inserted in the corresponding slots on the backplane tray, then attached to the backplane with a pre-installed clip. The connector has a latching system that grips the backplane firmly and ensures a secure connection. The group separator ensures that the pins of each group are properly aligned and insulated. The MMD25-0141R1 backplane connector uses a double-ended contact pattern to provide a redundant and reliable connection. Each contact ribs are designed to prevent misalignment and bending. The contacts have three contacts in a row to ensure an alternating positive and negative connection. The elimination of the redundant pin ensures that the contact has a longer lifespan and less fatigue failures, while the contact design helps to reduce conductor-to-insulator contact separation.

Summary

The MMD25-0141R1 backplane connector is designed for demanding applications, such as military and aerospace applications that require reliable power and signal transmission. The double-ended contact pattern provides a redundant and reliable connection, and the color-coded coding systems facilitate installation. The high-grade thermoplastic material used to construct the connector ensures that the connection retains its integrity in extreme temperatures and harsh environments.
