New connector preserves high performance in vibration environments

Hirose has developed the FX26, a high contact reliability connector with a -40C to 140C operating temperature, that preserves high performance in vibration environments, including on-board powertrain.


While the shift to hybrid cars and EV is gaining momentum worldwide, the motors and inverters used in these eco-cars are always subject to problems of heat generation and vibration. Also, the lifespan of a car, which was said to be 10 years and 100,000 kilometres, is rapidly increasing, so vehicles must be able to be operated safely for a long period. Therefore, automotive connectors also have to be tough enough to withstand the high heat and vibration conditions of powertrains for long periods.


The market needs for heat resistance and vibration resistance were used as criteria for these products. The company has developed a product that meets in-vehicle quality. A unique floating structure resolves the problem of contact failure caused by vibration.


The newly developed connector can satisfy the demands of powertrain control systems for existing electric vehicles and hybrid vehicles.
