Backplane Connectors - Contacts

1766111-2 Application Field and Working Principle

1766111-2 are backplane connectors created by Texas Instruments that are popular in a vast array of industries for a variety of applications. Typically used in conjunction with motherboards, these connectors feature a contact array insert that allows them to connect directly to printed circuit boards. 1766111-2 connectors are highly versatile, and can easily accommodate any type of digital, analog or mixed-signal powered devices.

Application of 1766111-2 connectors range from telecommunications, industrial automation, military/aerospace, automotive, and medical equipment industries. These fields require a variety of contact arrays to support different data, power, and signal requirements. Because of their popularity, 1766111-2 connectors are found in virtually any type of industry in one form or another.

1766111-2 connectors feature a contact array comprised of high-speed data transmission requests. The higher the number of contacts in the array, the denser the signal is in transmission and the faster the data can travel. Typical contact array sizes include 1X21, 2X21, 3X21, 4X10, 8X2 and 16X2. Contact spacings of 0.5mm, 1mm, 1.5mm, and 2mm are also supported.

In addition to contact array sizes, the thickness of the printed circuit board (PCB) to which the connector is designed to mate must be taken into account when specifying a 1766111-2 connector. The appropriate PCB thickness for mating with the 4X10 connector is 1.6mm, while a 8X2 connector would require a 1.2mm PCB thickness.

In terms of working principle, 1766111-2 connectors are created to provide reliable, dependable, and long lasting electrical connections. These connectors feature a three-piece design consisting of an insulator body, contact array and contact support. The contact support provides a stable surface for the terminals of the mating plugs to sit when the two components are mated. This is important, as the contact array must firmly support the two mating plugs regardless of how the connector is handled.

The contact array is made of a durable material such as copper or beryllium copper which prevent them from wearing down, even with repetitive mating and unmating. The contact array also features a floating-pin design, which ensures a secure contact regardless if there is any misalignment or gaps between the two mating connectors. All of these components are supported by a resilient insulator body that provides rigidity and reliability.

In short, 1766111-2 connectors from Texas Instruments are a go-to choice for industries where reliable and fast interface connections are essential. These connectors boast a versatile contact array design, as well as a robust three-piece design, making them one of the most reliable and dependable connectors on the market.
