What is the purpose of a wiring harness? How to use a wiring harness correctly?

A wiring harness is an important component of an electrical system used to connect circuits, electrical components and power sources. Its main function is to transmit electrical energy and signals to ensure proper communication and operation between appliances and equipment. A wiring harness consists of different sizes of wires and connectors that can be customised to suit a variety of different application scenarios.Electronic wiring harness

Here are some of the common roles of wiring harnesses

Transmitting current: Wiring harnesses can transmit electrical energy, delivering energy from the power source to appliances and devices for their normal operation.New energy wiring harness
Connecting circuits: Wiring harnesses can connect different circuits together through connectors to form a complete electrical system.
Protecting circuits: Wiring harnesses can protect circuits from external interference and damage, improving the reliability and safety of electrical systems.Aviation wiring harness
Control signals: Wiring harnesses can transmit control signals, such as start, stop, switch and other signals, to control the operation of electrical appliances and equipment.
Transmission of data: the wiring harness can also transmit data signals, such as sensors, communication devices and other data transmission.
The correct use of wiring harnesses requires attention to the following points:

Choosing the right wiring harness specification: It is important to choose the right wiring harness specification according to the parameters of power, voltage and current of the appliance to ensure that the wiring harness will not be overheated or overloaded.
Correct connection: The connection of the wiring harness should meet the specification requirements to ensure a firm connection and good contact to prevent current leakage and connector damage.
Prevent interference: Be careful to avoid external interference, such as high temperature, corrosive substances, etc., when using the harness to prevent adverse effects on the harness.
Regular Inspection: The wiring harness should be inspected and maintained regularly, including checking whether the wires are broken, whether the connectors are loose, etc., in order to ensure the normal use of the wiring harness.
Safe use: Pay attention to safety when using the wiring harness, avoiding direct contact with the wires and connectors to prevent electric shock accidents.
