Announced "10127 series" connectors for Electric car powertrains

On May 29, 2020, IRISO (Headquarters: Yokohama City, Kanagawa Prefecture; Representative Director: Ikuo Yuki) announced that in addition to the "10120 Series" Board to Board Connectors for internal connection that also has a resonance absorption function, a low profile type. "10127 series" has been added to the line-up, with a board-to-board spacing of 8mm to 30mm.
The "10127 series" connector is a Board to Board Connectors for internal connection developed for drive power train applications, which is necessary for Electric car such as EV/PHV/HV as automobiles become more electrified (2.0mm pitch, Floating Z direction). We have adopted our unique Floating structure technology "Z-Move structure ™" for use in severe vibration environments. The Z-axis can Floating while the contacts are fixed, making this connector excellent in vibration and impact resistance.

Major features

Feature 1: low profile /miniaturization
The board Mating height of 8mm, which is low profile than the minimum board Mating height of 11mm of the existing 10120 series, has been added, contributing to the miniaturization of devices. Our original "Z-Move structure ™" technology absorbs substrate resonance and exhibits high contact reliability because the contact follows resonance in the Z direction. This prevents deterioration of contact reliability due to fretting wear. We also offer a unique vibration simulation service that reflects our past evaluation results. By cooperating with the customer from the initial design stage, it is possible to propose more effective usage.
Feature 2: High temperature support
High heat resistance is also required for connector products due to the increase in heat generated around the engine of in-vehicle equipment and the increased functionality of devices. Highly heat-resistant products realized by making full use of materials and design technology are products that can be used safely even in harsh high-temperature environments.
Feature 3: Automation Connector
Robot assembly contributes to assembly quality, stable production takt time, and reduction of labor wages, but process defects such as foreign matter adhesion, mounting/ Mating misalignment, and incomplete Mating may occur. Based on the technology we have cultivated so far, IRISO has launched the concept of a connector suitable for robot assembly, "Automation Connector".
We propose a product that has a "Floating structure" function that absorbs board misalignment and a "two-point contact" function that removes foreign matter adhesion as a "Automation Connector."
