Rectangular connectors, edge-type arrays, and mezzanine board-to-board connectors are useful for a variety of applications across a broad spectrum of industries. The application field and working principle of the 45970-3115 connector is discussed in this article.

Application Field

The 45970-3115 connector is designed for electric or electronic signals with data rates of 6-10Gbps and transmission line impedance levels of 100-85Ω. This type of connector is typically used as part of a larger system, such as a computer system, needing high bandwidth and reduced cross talk between interface signals. It is also used in communications in wireless and electrical equipment, including radios, TVs, medical systems, and industrial automation systems. Due to its small size, it can be used in compact systems, such as in space exploration apps and portable devices.

Connector Characteristics

The 45970-3115 connector is a single-piece design with a 19-pin arrangement. It has plated contacts with a high dynamic range and low crosstalk for maximum signal integrity and noise immunity. It is designed for low insertion loss, with an expected loss of 0.3 dB or less. The connector is rated at IP67, meaning it is dust tight and waterproof when properly secured.

Working Principle

The 45970-3115 connector works by transmitting high-speed electrical or electronic signals between two boards, typically over a cable. It supports efficient signal transmission and reduces interference between signals by providing a low impedance environment. It also helps reduce crosstalk, meaning the distortion of signals caused by adjacent signal frequency components. As a result of this, it is suitable for applications needing high-speed and low-noise data transmission.

Heat Dissipation

The 45970-3115 connector is designed with a solder tail, which helps dissipate heat, and a jacket that aids in air ventilation. Heat created by transmitter and receiver components when transmitting digital signals can be effectively dissipated with the use of an effective heat dissipation system. Heat dissipation is necessary to ensure the reliability of the signals and the various system components.

Assembly Procedure

When assembling the 45970-3115 connector, it is important that the proper tools are used so that the pins are properly aligned and the connector contacts securely fit into the mating surface. Before assembling, the contacts should be checked for any mechanical deformation and cleaned with the use of an appropriate solvent. Prior to soldering, the solder is applied to the contact surface. Suitable insulation should be applied after soldering to protect against shorts. After assembly, a functional test should be conducted to ensure that the electrical connections are secure and that the performance specifications are met.

Conclusion

The 45970-3115 connector has a wide range of applications and is suitable for both high-speed signal transmission and low-noise signal transmission. It has a 19-pin arrangement and is designed for low insertion loss and low crosstalk. The connector provides an effective heat dissipation system and should be properly assembled to ensure its reliability and performance.
