91911-31451

The 91911-31451 type rectangular connectors belong to the Arrays, Edge Type, Mezzanine (Board to Board) family. These mid-sized connectors offer a reliable solution for engine-powered car systems. It features an increased amount of pins for easier implementation of applications, and its shape makes it easier to fit in tight spaces.

This type of connector is designed for applications which require increased heat dissipation or power protection compared to traditional rectifier connectors. It consists of two perpendicular arrays of mating surfaces, normally used to connect a printed circuit board with a component mother board. The 91911-31451 connectors feature slots, holes, and tabs that lock two printed circuit boards into place while aligning them with relative ease. This allows for a secure and precise fit, preventing deformation from external forces.

The 91911-31451 connectors offer soldering methods such as wave, head on, or steady. The terminals are placed in a staggered array that ensures a precise fit in diagonal directions, allowing for secure installation. Apart from the soldering process, riveting and cold heading can also be used. Depending on the installation requirements, an optional locking fastener can be included. This fastener temporarily holds the boards together for ease of installation.

In terms of working principle, 91911-31451 connectors offer low electrical resistance to provide reliable transmission of power and signals. They are usually rated for working voltages of up to 7.5V DC and current ratings ranging from 5 to 12A. To ensure the safety of the user, they are UL-recognized and soldered parts are RoHS-compliant. Connection points with soldered mating surfaces have an anti-corrosive coating to protect against water ingress and long-term insulation.

Overall, the 91911-31451 connectors are an ideal fit for applications requiring increased heat dissipation or power protection combined with reliable transmission of signals. The staggered array of slots, holes, and tabs of the connectors make them suitable for precise fits in tight spaces and safely transfer electrical power with low electrical resistance. With features such as soldering methods, optional locking fastener, anti-corrosive coating, and UL recognition, the 91911-31451 rectangular connectors are a reliable choice for engine-powered car systems.
