Today\'s advanced electronics require a wide range of signal and power connections in a variety of shapes and sizes, and rectangular connectors - arrays, edge types, mezzanine (board to board) are all excellent examples of connector designs that provide these connections. The 91920-31141 rectangular connector is a welcome addition to the array of options available to designers, providing a reliable, cost-effective and compact solution for a variety of applications. In this article, we will look at the 91920-31141 application field and working principle.

The 91920-31141 signal/power rectangular connector is a two-piece, vertically-mounted surface-mount connector, designed to allow two printed circuit boards to be mechanically and electrically connected. The female connector is attached to one board and the male connector to the other, with minimal contact resistance. It has a peak voltage rating of 8.5 and a current rating of 1.5 A. It is UL Rated UL1977, CSA LR19812, EN 60950-1 and EN 50557 with an operating temperature range of -55 to +85C.

The 91920-31141 connector features a unique floating and hinged mounting plate design that allows for easy and accurate installation of the array on the printed circuit board. This design also ensures a higher strength to weight ratio, reducing the amount of material needed for a successful installation and reducing the overall weight of the connector. The connector also features a 90-degree offset between the male and female connectors for improved stability, preventing the connectors from bending or twisting during mating.

The 91920-31141 uses a series of flat contacts that are arranged in a specified rectangle, ensuring high reliability and repeatability throughout the life of the product. These contacts possess a raised edge that securely locks into the receiver slot during mating, providing greater contact pressure, higher signal integrity, and improved current carrying capacity. The connector also features an optional shoulder spring contact that helps reduce misalignment during mating while maintaining electrical continuity of the contacts. Additionally, the connector is coated with a special insulation material that helps to protect the contacts from electrostatic discharge.

In terms of applications, the 91920-31141 connector is best suited for small industrial, automotive, avionic and marine applications, or for power management and lighting systems. Additionally, this versatile rectangular connector can also be used in aerospace, medical, and telecommunications applications, as well as in high-speed data and communication systems. It is an ideal choice for tight space operations, providing reliable and quick mating/unmating.

In conclusion, the 91920-31141 is an excellent example of a connector that provides designers with reliable signal and power connections in a variety of shapes and sizes. It is UL Rated UL1977, CSA LR19812, EN 60950-1 and EN50557, and has a peak voltage rating of 8.5 and a current rating of 1.5 A. It is best suited for small industrial, automotive, avionic, and marine applications, or for power management and lighting systems. Additionally, this versatile rectangular connector can also be used in aerospace, medical, and telecommunications applications, as well as in high-speed data and communication systems.
