1738008-1 Backplane Connectors - Contacts Application Field and Working Principle

The 1738008-1 backplane connector is a series of contacts designed for use in high speed backplane applications. The contacts are designed to provide low power attenuation and low insertion loss in a two-piece design (contact and housing) and are designed for an operating temperature range of -65 to +125 degrees Celsius. The 1738008-1 contacts have a robust design with precise tolerances that are capable of withstanding high levels of vibration, shock, and cyclical loads. The contact and housing are designed to help reduce EMI/RFI and are compatible with all popular backplane connector systems.

The contact design of the 1738008-1 utilizes a unique strain relief feature that helps to keep the contact from being damaged during mating or unmating. The contact is comprised of four segments—the contact tooth, contact sleeve, contact body, and contact cavity—that are designed to work together to provide optimal electrical performance and strength. The contact tooth has a flat, chamfered surface that allows it to fit into the contact body, while the contact sleeve helps to provide strain relief and support.

The 1738008-1’s housing design consists of an integral shield and two metal clamping shells with four captive screws. The shield helps minimize the ingress of foreign material into the connector as well as minimizes EMI/RFI. The clamping shells are designed to snap and lock onto a printed circuit board (PCB) via latches and create a tight connection to the PCB. The four captive screws secure the contact to the housing and provide mechanical and electrical connection.

The 1738008-1 is designed to be used in a wide variety of applications in the industrial, computing, telecommunications, aerospace, and medical industries. The 1738008-1 is typically used in high-speed backplane applications, such as 10G or 25G Ethernet, USB3.0/USB3.1, and Serial ATA (also known as SATA) applications. The contact enhances board-level signal integrity, reduces power loss, and provides a highly reliable connection. The contact also features high-temperature range and robust design for high vibration and shock environments.

In terms of electrical performance, the 1738008-1 contact is designed to provide low power attenuation and low insertion loss. This is achieved through the combination of the contact design and housing design, which work together to reduce EMI/RFI. Additionally, the contact features a low contact resistance of less than 7 milliohms (mΩ) and a maximum current rating of up to 5A.

The 1738008-1 contact is designed for high-speed backplane applications and features a robust two-piece design. The contact and housing combination reduce power loss and EMI/RFI, while providing a highly reliable connection. The contact is designed for an operating temperature range of -65 to +125 degrees Celsius, and features a low contact resistance and maximum current rating of 5A. The contact is typically used in systems such as 10G or 25G Ethernet, USB3.0/USB3.1, and Serial ATA applications. The contact provides board-level signal integrity, power loss control, and a highly reliable connection. This makes the 1738008-1 contact a suitable choice for high-speed backplane applications.
