Backplane connectors are contacts which are used to connect different modules, printed circuit boards, or other discrete components in backplane assemblies, and can be a key component in the overall reliability of a system. The 148354-1 contact is a high-density, zero-insertion-force (ZIF) socket connector which is the most commonly used in commercial and military applications. It is designed to provide quick and secure connections while ensuring maximum contact integrity and terminating on a straight-through bus configuration.

Design Features

The 148354-1 contact features a robust design which includes an integral latching system and a power ramp feature. The integral latching system provides a high degree of retention without the need for additional components. The power ramp feature reduces resistance and electrical noise by providing a smooth, low-resistance interface for large signal transmission. The socket contacts are constructed with high-temperature, high-reliability thermoplastic housing material which meets the requirements of MIL-SPEC 46386.

Performance Advantages

The 148354-1 contact is designed to withstand shock, vibration, and thermal shock in accordance with MIL-STD-202E. It is rated for up to 500 mating cycles and offers a current carrying capability of up to 15A with an operating temperature range from -55°C to +125°C. The contact has a contact resistance from 0.2 ohms to 0.5 ohms and meets MIL-PRF-39008 requirements.

Applications

The 148354-1 contact is suitable for a wide range of backplane applications, including data and communications systems, video systems, power supplies, electronic switches and relays, and instrumentation systems. It is also suitable for use in the oil and gas industry as well as the automotive and aviation industries.

Working Principle

The 148354-1 contact uses a ZIF (zero-insertion-force) design which requires no tools to lockout and prevent accidental disconnection. The contact features a quick-connect system which allows the contacts to be easily installed and removed in seconds. The contact is a two-part connector where the male plug portion contains pins and the female socket portion contains open ended holes. To make a connection, the pins of the male plug must be aligned with the corresponding holes of the female socket, then the parts must be mated and pushed together until a latch engages. The latch holds the parts together and provides secure electrical connection with low contact resistance.

Conclusion

The 148354-1 contact is a robust, high-density contact offering reliable electrical connection for a wide variety of backplane applications. This contact is designed to provide quick and secure connection while providing maximum contact integrity and terminating on a straight-through bus configuration. Its robust design, high-reliability materials, and high current carrying capacity make it an ideal choice for applications requiring reliable, high-density contacts such as military, automotive, and aviation.
