Wiring Harness

A communication interface is an interface used for data transfer and communication between devices. Common communication interfaces include USB interface, HDMI interface, VGA interface, Ethernet interface, wireless network interface, etc. These interfaces can be used to connect computers, external devices, network devices, monitors, printers, etc. to realize data transmission and communication functions. 

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

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.

As the demand for intelligent driving systems and in-car entertainment systems in automobiles grows, the in-car signal transmission rate increases, leading to a gradual increase in the transmission frequency of the corresponding connecting cables.

FAKRA coaxial cable is a high-speed high-frequency cable that transmits RF and HD camera signals. Mainly includes the FAKRA connector, FAKRA Inline connector, coaxial cable, and PCB board end connector.

What is RF Cable

RF cable, also called coaxial cable, is a wire and signal transmission line. It consists of a mutually coaxial inner conductor, an outer conductor, and a medium that supports the inner and outer conductors. Coaxial cable is generally composed of four layers of material: the innermost is a conductive copper wire. In contrast, the outside of the wire has a layer of plastic (used as an insulator or medium) around it. Outside the plastic, there is a thin layer of mesh conductor (usually copper or alloy), and then the outermost is a layer of insulating material as the outer skin.

RF cable is an indispensable component of various radio communication
