Japan develops evaluation equipment for connectors for automotive wiring harnesses

Tetsuo Shimizu, director researcher of the Nano-Optoelectronics Application Research Group of the Nanosystem Research Department of the National Institute of Advanced Industrial Science and Technology, announced that the organization and Yazaki Corporation of Japan have jointly developed a connector evaluation equipment for automotive wiring harnesses, contributing to
the miniaturization and weight reduction of connectors for automotive wiring harnesses.

Using the equipment developed this time, the indentation is created under an electron microscope

Connectors for automotive wiring harnesses are tinned on copper plates and then commercialized
.
The evaluation equipment developed can observe the contact with metal from a scanning electron microscope, and also measure the contact load and resistance
of the connector.
The tin-oxide film on the separation surface can be confirmed by the indentation made by this equipment, and the prepared tin can be introduced from the separation site to form a good electrical contact
.

The evaluation equipment and measurement results regarding electrical contacts are expected to contribute
to the evaluation and new product design guidelines for connectors for automotive wiring harnesses that pursue high trust and compact and lightweight size.

It is reported that this automotive wiring harness connector evaluation equipment will be released
at the international conference on electrical contacts to be held in New Orleans, USA, from October 12 to 15.
