Connector/Connection
Connectors and their contact solutions, a core part of wire harnesses, are in the domain of our research and development. Our offer comprises of varieties of products such as low voltage connectors responding to the needs of size reduction and high vibration resistance, high voltage connectors for HEVs, PHEVs, and EVs, and electronic components, mechanical parts and equipment. For the low-voltage category, we develop waterproof multi-pin connectors and compact waterproof connectors used in engine ECUs and airbag ECUs. For the high-voltage segment, direct connectors applicable to HEVs are one of our major development items.
Electrical connection is an essential factor in connector development. Our research and development approaches the design of fundamental theories and analysis in overall connection technology, evaluation methods, and required materials and processes.
Ultra multi-pin connector
Ultra multi-pin connector that meets a growing need of "connectors that meet the increased number of circuits" and "reduction in fitting force"
Compact waterproof connector
Compact connector capable of withstanding harsh vehicle environments.
HEV connector
Device-integrated connector. Its key feature is the structure capable of absorbing tolerance generated when assembling the inverter on top of the motor.
Busbar module
-
Busbar between cells
-
Voltage detection circuit (terminal)
This busbar module improves the ease of assembly and energy density of high voltage battery packs. Our connectivity technology focusing on space saving contributes to develop this product.
Solution for aluminum contact
-
Connection for thin aluminum wires
-
Connection for thick aluminum wires (20mm²）
This serration was developed for terminal crimping of thin aluminum wires. By breaking strong aluminum oxide film, it can provide a stable electric connection.
The ultrasonic welding has been developed for connecting thick multi-strand aluminum wires. It is capable of connecting wires without forming a brittle layer on the connection surface which degrades welding quality.
