Small power interface connector with vibration resistance and waterproof performance
High Voltage connector HVH-280 series for automotive

The high voltage HVH-280 series consists of compact power source interface connectors intended for use in electric equipment such as automotive inverters, DC/DC converters, and chargers used in HEV and EV driving systems, which are rapidly spreading.
Reducing the volume and weight of electric components in the drivetrain directly leads to improvements in vehicle performance such as passenger comfort and fuel efficiency. Therefore, there is a need for a smaller component. The HVH-280 series achieves a size reduction of approximately 40% compared to products with comparable specifications from other companies.
By taking advantage of HVH-280's compact size high voltage capability, vibration resistance and waterproof characteristics, the size of HEV and EV drive systems is reduced as well leading to higher added value in applications.

Features
Substantial reduction in mounting area. Miniaturization of automotive inverters and other electrical equipment
By optimizing the panel mount design, the installation area has been greatly reduced. While maintaining a current capacity of 30A, this product is 16mm high and about 40% smaller in height compared to other products with similar specifications.

High waterproof performance with IPX9K
Each part of the wire housing panel is waterproof machined to withstand even high pressure cleaning. It can be used safely as an interface connector for automobiles and industrial equipment intended for use in harsh environments.
IPX9K waterproof property (Test conditions): Tested at a water pressure of 8-10 MPa and a water temperature of 80 ± 5 ° C from a distance of 100-150 mm in 4 directions for 30 seconds each.

Water resistance tester

Salt spray cycle tester
Adoption of CPA mechanism to ensure secure fitting
The use of a CPA (Connector Position Assurance) mechanism ensures a secure fit and prevents malfunctions due to incomplete mating.

Prevent electric shock accidents and ensure operator safety
An internal mating detection circuit ensures the safety of workers. To prevent electrical shock hazards, set the product so that no current flows to the power terminal unless the detection signal terminal and power terminal come in contact.
*When using the interlock mechanism, it is necessary for the customer to assemble the circuit.

Excellent noise resistance
Metal shields and the ground contacts ensure total EMI prevention.
Vibration resistance
It has the performance to pass the 8.9G vibration test and can be used in environments where strong vibrations are applied.

Applications (Use Case)
In cases where the application will demand a high level of reliability, such as automotive, please contact a company representative for further information.
