Backplane connectors provide an electrical interface between two printed circuit boards (PCB’s)within an electronic device.The type of connector selected is based on a variety of criteria including size, environment, voltage and current. An example of a specialized backplane connector is the 51915-004. This article briefly explores this connector’s application fields and working principle.

Application Fields

The 51915-004 is a high-speed backplane connector designed for optical communication, used when transmission line length must not be exceeded or when signal integrity is of particular importance. The connector is designed for high-speed, low-voltage applications, with Gigabit Ethernet transmission speeds up to 1000 Mbps. The 51915-004 has nine positions available for hookups, making it suitable for SCSI and comparable interface applications. It is suitable for use in both industrial and commercial applications including computer servers, switches, routers and storage systems.

Design and Structure

The design and structure of the 51915-004 are simple and durable. It has a robust plastic body that includes a self-adhesive backing, making it easy to install. The contact is made up of a soldered copper pin that is surrounded by a stainless steel dielectric. The contacts are designed in a contact-pairing array that ensures reliable electrical contact during operation. It is available in a variety of PCIe, SATA, SAS and USB3 configurations.

Working Principle

The 51915-004 functions through the transmission of electrical signals through an internal copper trace. The trace connects two pins in the faceplate of the connector. These pins, in turn, are connected to the PCBs through a soldering process. The pins transmit the electric signal through the copper trace, which picks up an analog voltage representing an electrical signal. The signal then travels through the connector and passes onto the PCBs. Once the signal reaches the PCBs, it is amplified and sent out onto the network interface.

Features

The 51915-004 boasts a number of features that make this type of connector particularly effective. This connector is dust-proof and waterproof, making it suitable for use in outdoor and marine environments. In addition, the connector features a gridless wiring system to reduce cross-talk and improve signal integrity. The solder-less contacts also provide a secure and reliable connection, ensuring integrity between the contacts. Furthermore, the connector has an integrated ground-loop protection, making it ideal for use in applications requiring high level of isolation.

Conclusion

The 51915-004 is a specialized backplane connector that is ideal for high-speed, low-voltage applications. It is dust-proof and waterproof, making it suitable for use in a variety of environments. Its features include a gridless wiring system to reduce cross-talk, solder-less contacts, and integrated ground-loop protection. These features make the 51915-004 an effective connector for applications requiring high level of isolation and transmission line length requiements.
