High Voltage Connector

Whether it is a high-voltage electrical connectors, or low-voltage electrical connectors, insulation resistance, dielectric strength (also known as electrical strength) and contact resistance are to ensure that the electrical connectors can work properly and reliably the most basic electrical parameters. Usually in the technical conditions of the electrical connector product quality consistency inspection A, B group of conventional delivery inspection projects are listed in the clear technical specifications and test methods. These three tests are also an important basis for users to identify the quality and reliability of electrical connectors. 

In addition, with the rapid development of electronic information technology, a new generation of multi-functional automatic testers are gradually replacing the original single-parameter tester. The application

Last paper mainly expounds the basic composition, various classifications, design elements, fault analysis and corresponding measures of high-voltage connectors.

In this paper we will introduce the main points of the design of high-voltage connector contacts, connector insulation structure design, anti-vibration design, anti-rotation structure design, high-voltage resistance performance design.

1. High-voltage Connectors Contact Parts Design Points

The contact connection technology mainly examines the contact area and contact force, including the contact connection between the terminal and the wire, and the contact connection between the terminal and the terminal.

The reliability

High-voltage connectors, also known as high power connectors, are a type of automotive connectors, generally referred to as connectors with operating voltages above 60V and mainly responsible for transmitting high currents.

High-voltage connectors are mainly used in the electric vehicle high-voltage high-current circuit, and the role of the wire at the same time, the energy of the battery pack through different electrical circuits to the entire vehicle system components, such as battery packs, motor controllers, DCDC converters, chargers and other high-voltage components.

At present, there are three main standard systems for high-voltage connectors, respectively, the

There is no doubt that new energy vehicles are one of the popular development directions in the passenger car field at present. New energy vehicles are significantly different from traditional fuel vehicles. In particular, pure electric vehicles will not be able to perceive their working condition and judge the safety status of the vehicle through obvious shaking, smell, heat and other ways like fuel vehicles. Therefore, other approaches are needed to ensure the safety and reliability of the vehicle during operation. High-voltage insulation detection and high-voltage interlock loop are essential technical solutions.

At the same time, in order to ensure that the high-voltage

In the high-voltage circuit of an electric vehicle, the main electrical component of the hvil system is the high-voltage connector. However, the manual maintenance switch (MSD) is a human-operated element that serves as the electrical interface for circuit turn-on/break-off.

On the one hand, it initiates the protective measure of safely disconnecting the high-voltage electricity when the circuit of the high-voltage system is disconnected, or its integrity is damaged. On the other hand, it is used to confirm the integrity of the entire high-voltage system.

Automotive high-voltage wiring harness (high-voltage cables and high-voltage interfaces) is a key component of the high-voltage electrical system, providing reliable operation and safety of electric vehicles. The main development and design solutions for the whole vehicle high-voltage harness involve cable layout, cable diameter selection, high-voltage connector selection, charging cable and interface types and applications, cable fixing and protection, etc.

The Whole Vehicle Layout of High Voltage Harness

The high voltage connection harnesses between each high voltage component, such as a battery to PDU, motor controller to the motor, AC/DC charging, etc., are reasonably arranged by the layout position of the high voltage components of the electric vehicle.
