High-voltage connectors for HEV power sources

Higher voltages than the conventional are used in the battery for hybrid vehicles and electric vehicles, in order to obtain higher power while reducing heat generation in every part, by using higher voltages and lower currents. However, higher voltages constitute, along with assuring insulation and waterproof property, a major factor for increasing the size of connectors.

In response to such requirements, this product has achieved, by adopting a variety of technique in designing the connector structure, both assured insulation and compact size.
