Q: What types of applications is this 4 pin connector designed for?
A: This Neopower 4 pin connector is engineered specifically for high-power, high-voltage applications where reliability is critical. It is ideal for core components in electric vehicles (EVs) and industrial machinery, such as On-Board Chargers (OBC), Power Distribution Units (PDU), PTC heaters, and air conditioning compressors. Its robust design ensures stable performance in these demanding systems.
Q: Can this connector be used in electric vehicle (EV) systems? A: Absolutely. This connector is designed with the automotive industry in mind. Key features like the integrated High-Voltage Interlock (HVIL), a wide operating temperature range (-40°C to +125°C), and 360° shielding make it a perfect automotive connector for ensuring safety and performance in the complex electronic environments of modern EVs.
Q: Is this high-voltage connector waterproof and suitable for harsh environments?
A: Yes, it is. The connector is rated at IP67 and IP6K9K. This means it is fully protected against dust ingress (dust-tight) and can withstand both temporary immersion in water (IP67) and high-pressure, high-temperature water jets (IP6K9K). This makes our waterproof connector exceptionally durable for use in exposed or harsh industrial and automotive environments.
Q: What is the purpose of the High-Voltage Interlock (HVIL) feature?
A: The HVIL is a critical safety feature. It is a secondary circuit that ensures the high-voltage power is automatically and safely interrupted before the primary power contacts can be disconnected. This protects technicians and operators from potential electrical shock during maintenance or in the event of an accidental disconnection, making it a vital component for any secure high-voltage connector.
Q: How does this connector prevent incorrect installation and accidental disconnection?
A: This connector integrates two key design features for this purpose. First, it uses a Poka-yoke (error-proof) keying system, which means its physical shape only allows it to be mated in the correct orientation. Second, it includes a robust secondary locking mechanism that provides a secure physical lock, preventing the 4 pin electrical connector from disconnecting due to vibration or unintentional pulling.
Q: What is the maximum current this high-current connector can handle?
A: The connector's current rating depends on the wire gauge used. It is rated for 20A with a 2.5mm² cable, 30A with a 4mm² cable, and can handle a maximum of 40A with a 6mm² cable. This versatility allows engineers to use it across a range of power requirements.
Q: Why is 360° shielding important for this type of connector?
A: In modern vehicles and industrial equipment, many electronic systems operate in close proximity, creating electromagnetic interference (EMI). The 360° shielding provides a continuous, uninterrupted conductive path around the internal contacts. This blocks external EMI from disrupting the power or signal transmission and prevents the connector itself from radiating noise, ensuring signal integrity and reliable performance for the entire system.
