Is it auto wire harness? The auto wire harness is the network main body of the automotive circuit, and there is no car circuit without wire harnesses. The cable assembly refers to the connection between the contact parts (connectors) and the wire and cable that is made of copper materials, and then plastic the insulator or the metal housing on the outside to form a compone...
The main specifications and performance requirements of the auto wiring harness 1. The cross -sectional area of the wire Select the cross-area of the wire according to the load current of the electrical equipment. The general principle is that the electrical equipment that works for a long time can choose a wire with a actual load of 60%. The actual load volume of the actual load can be use...
The production process of the cable assembly & wiring harness The first process of wire production is the tailoring process. The accuracy of the tailoring process is directly related to the entire production progress. Once an error occurs, especially the short -wire size, it will cause the rework of all stations, and the time -consuming effort will affect production efficiency. The...
The full name of OBD is On Board Diagnostics The purpose of the OBD plug is to monitor whether the exhaust is over the limit by the running condition of the engine. Since then, the system has become more and more useful, basically monitoring emissions-related components in real time and sending that information to the driving computer to determine whether the vehicle is working properly. If...
What is An ECU? Electronic Control Unit(ECU) Explained Electronic Control Unit (ECU) is short for electronic control unit. From the point of use is the car special microcomputer. The function of modern automobile is more and more rich. Every subsystem of automobile needs powerful ECU to control the work of this system. For example, the transmission ECU adjusts the appropriate gear acco...
High voltage wiring harness technical requirements for electric vehicles 1. Dimensions, specifications, test methods and requirements for copper conductor cables and QC/T 1037-2016 high voltage cables for road vehicles. 2. Power line with plug-in adopts orange (RAL2010) insulation line specification; 3. Power cable requirements: 1) Conductor: stranded copper conductor (copper wire with diameter of...
The standard of the auto wire harness is different from that of ordinary electronic wire harness. Ordinary electric wire harness is a copper single stamen, with some hardness. The car wire harness are copper and soft wires, and some soft wires are as thin as hair. Several or even dozens of soft copper wires are wrapped in plastic insulating tube (polyvinyl chloride), soft but n...
The difference between electric vehicle wiring harness and ordinary auto wiring harness In recent years, the concept of new energy has become mainstream. Especially in the automotive industry, new energy electric vehicles have been vigorously launched. Their environmental protection, low-carbon and energy-saving characteristics just meet this demand. At the same time, most wiring ...
[Terminal] Instructions for the use of heat shrinking tube in wire harness After the heat shrinking tube is encountered, it has a different role in fully automatic diameter and smaller. Therefore, the specifications of thermal shrinkage and thermal shrinkage are generally marked in A/B, that is, the inner diameter is AMM pipes, which can be gathered at least to gather together To BMM. The thermal ...
The high voltage connector for new energy vehicles is an integrated electromechanical product, which is mainly composed of contact parts, insulators, shells, and accessories. Among them, the contact part is the core component of the connector to complete the light and electrical signal connection. Complete the connection of light and telecommunications required for vehicles during driving; insulat...
Among the new energy vehicles (pure electric as an example) high voltage cable assemblies can be divided into 5 parts 1. Power battery high voltage cable: that is, the wiring bundle between the power battery and the high voltage box. 2. Motor controller cable: that is, the cable connecting the high voltage box to the motor controller. 3. Fast charging wire harness: connect the cable assembly ...
I. Ultrasonic welding principle: Ultrasonic wiring harness welding is a commonly used process of car wire welding. The principle is to re -combine the surface of the welding material through high frequency vibration. Ultrasonic welding energy consumption is low, no pollution, strong welding and low internal resistance, and does not change the chemical properties of welding parts. Welding cond...
