New energy vehicle wiring harness connector

With the increase of automotive electrical equipment, new energy automobile wiring harnesses, and the number of wires in the wiring harnesses are also increasing. In order to facilitate identification and detection of automotive electrical equipment, low-voltage wires in the wiring harnesses are usually used with different wire colors. At present, two methods are generally used when selecting wiring: single-color line and two-color line. When using monochromatic lines as a basis, you can refer to the monochromatic line colors in Table 3. The power cord of each power system is monochrome.

Due to the increasing number of two-color lines in the vehicle, most of the wires in the wiring harness currently use two-color lines. The two-color lines are obtained by combining the above monochromatic colors. There are requirements for two-color wires. The wires in the above are taken as an example. For pdu new energy automobile wiring harness, YS means that the main color of the wire is yellow, which occupies most of the area of the wire, and the auxiliary color is gray, occupying only a small part of the wire. Partial area. The color of the wire is one of the intuitive elements of the wire in the wire harness. The connector of the new energy automobile, the color of the wire is properly selected, which plays a good role in the engineer's post-processing of the wire harness problem. In the same wire harness design, the new energy automobile wire harness connector cannot have the same wire color, and when choosing a color, try to choose a color combination with obvious contrast and easy to distinguish with the naked eye.

Automobile wiring harness is the main body of the network of automobile circuit. Without wiring harness, there is no automobile circuit. With the increase of people's requirements for the safety, comfort, economy and emissions of automobiles, automobile wiring harnesses have become more and more complex, but the space given to wiring harnesses by the body has become smaller and smaller. Therefore, how to improve the comprehensive performance design of automotive wiring harnesses has become the focus of attention. Moreover, automotive wiring harness manufacturers no longer simply engage in the post-design and manufacturing of wiring harnesses, and it has become an inevitable trend to jointly develop with automotive main engine manufacturers in the preliminary development. Based on the experience in wire harness design and manufacturing for several years, the author talks about the general design process and design principles of wire harnesses.

The characteristic of the fusible wire is that when the line passes a great overload current, the fusible wire can be blown in a certain period of time (generally ≤ 5s), thereby cutting off the power supply and preventing the occurrence of evil 1 accidents. Fusible wire is also composed of a conductor and an insulating layer. The insulating layer is generally a chlorosulfonated polyethylene material. Because the insulating layer is thick, it is considered. It is thicker than wires of the same specification. New energy vehicle wiring harness service hotline.

There are two types of relays: current and voltage. Generally, whether to choose a relay is based on the power of the consumer and the carrying capacity of the switch. Commonly used relay devices include wipers, horns, defrosting, headlights, fog lights, fans, blowers, turn signals (flashers), etc. There are 3 types of relays, 6V, 12V, and 24V. The commonly used relays have a rated voltage of 12V. The technical requirements to refer to when selecting relays are: ① good reliability; ② stable performance; ③ light weight, small size, long life, and small impact on surrounding components; ④ simple structure, good workmanship, and low cost.
