Development trend of electronic wiring harness

Electronic wiring harnesses, which connect and function electrical and electronic components of a car, act as “nerves and blood vessels” in the car.  The wire harness consists of the wires that constitute the circuit, which not only ensures the transmission of electrical signals, but also ensures the reliability of the connected circuit, provides specified current values to electronic and electrical components, and prevents electromagnetic interference to the surrounding circuit.  And eliminate electrical short circuit.

The functions of the automotive electronic wiring harness are divided into two types, one is the signal line that carries the input instructions of the sensor, and the other is the power line that carries the electricity that drives the executive element (actuator).  Signal lines are thin lines without electricity (optical fiber communication), and power lines are thick lines that carry a large current.  The greater the cross-sectional area of the wire, the greater the current capacity.  On the choice of wire, besides considering electrical performance, still suffer the restriction of physical performance when the vehicle runs, so its choice range is very extensive.

For example, the taxi often open the door and through the body of the wire should be made of flexible wire high temperature area conductor is generally used vinyl chloride and polyethylene coated conductor, insulation and heat resistance is good in recent years, for weak signal circuit electromagnetic shielding line is also more and more.

In addition, electronic wiring harness and electronic, electrical system components, an important component of the circuit – connectors have been continuously developed and improved in recent years. For example, a resistance welding can be used to manufacture automotive connectors and new wire harness material research success is mainly applied to the roof module.
