The EU has always been committed to green and environmental protection, such as the pursuit of electronic products interface unity, and the big red USB-C is obviously the best choice at present, so the EU decided to pass a decree so that all electronic products must use USB-C interface, the deadline is 2023, and by 2024, the EU finally announced the law into effect. All electronic products sold in the EU must use the USB-C interface. The European Commission said on social media that through unremitting efforts, the USB-C interface will become the standard of electronic products in 2024, which we believe means better charging standards, cable waste will be greatly reduced, and everyone will be more convenient to find a charger. The EU says that in the future, all USB-C chargers should be able to charge electronic devices with USB-C ports without compatibility issues. In this EU list, including mobile phones, tablets, digital cameras, headphones, game consoles, e-books, keyboards, mice, mobile GPS and other devices must use USB-C interface, and by 2026, all laptops must use USB-C interface. The EU's move to unify all its interfaces is a huge step forward. After all, in the past due to the immaturity of technology, there were dozens of interfaces on the market, and later with the rise of USB, basically Micro-USB, Apple lighting and Type-C have become the three major universal interfaces, and Micro-USB is almost eliminated, the remaining biggest resistance is Apple lighting interface. For the EU move, Apple expressed strong opposition, saying that the unified interface will only erase personality. Of course, the huge market of the European Union has also made Apple have to lower its head and adopt the Type-C interface in the iPhone 15 Pro, and with the landing of this bill, we can casually find a Type-C line in the future to achieve charging and data transmission of digital products.   Aichie Tech is specialized in the production and processing of various types of wire harnesses, such as: Type-C wire, new energy wire harnesses, robot wire harnesses, industrial equipment wire harnesses, injection molding wire harnesses, etc. The factory introduced automation equipment, and passed the ISO9001, ISO13485,IATF16949 and other treatment system certification; Aichie for UL, CUL listed companies, to provide customer product protection, reliable quality and competitive prices, welcome to consult! sales03@aichie.com

On April 20, Tesla released the first quarter of the 2023 financial report. According to the financial report, Tesla's revenue in the first quarter was about $ 23.33 billion dollars, an increase of 24%year on year; net profit was about $2.513 billion dollars, and the operating profit margin was 11.4%. In addition, Tesla operating cash flow was $2.5 billion dollars, and the free cash flow in the first quarter was $ 400 million.       Since 2023, Tesla has opened a price reduction strategy worldwide, and even in certain areas, the price reduction has been reduced more than once. But it is terrible that although Tesla's profit margin fell more than 10%, it was still considerable: in the first quarter, it still maintained an 11.4% level, which was higher than many car companies.   According to Tesla, although the price of some models in different regions in the first quarter, the decline in operating profit margins is still controllable. At the same time, Tesla also expects vehicle costs to continue to decrease.     At present, Cybertruck is producing the Alpha version. When Cybertruck successfully begins to deliver and complete production capacity climbing, it is estimated that Tesla's revenue and profits will continue to increase. Perhaps this is the biggest impact of large -scale production on the manufacturing industry.     Tesla's price adjustment in the United States, price increase and price reduction coexist On April 20, the official website of Tesla showed that the price of Model Y long battery life and the high -performance version was reduced by $3,000 US dollars, and the price of the Model 3 rear -wheel drive version was reduced by $2,000 dollars.       At the same time, the price of Tesla Model S and Model X was raised by $ 2,500 in the United States. At present, Model S is priced at $ 87,490, Model S Plaid is priced at $ 107,490; Model X is priced at $ 97,490, Model X Plaid is priced at $ 107,490.   This kind of rising and falling situation perfectly explains the principles of Tesla's "cost -based pricing". Model 3 and Model Y are already the sixth time to reduce prices in the United States. Musk also hinted that although Tesla's price reduction measures at the beginning of this year have affected profit margins (profit margins have fallen by 10%and the market value evaporates $50 billion), Tesla will continue to reduce prices to stimulate demand. It is conceivable that Tesla's continuous price cuts will continue to impact the new energy market in the USA.   Aichie provides high -quality busbar low -voltage auto wiring harness and high voltage ev cable assembly around the world.

Cables: all cables consist of three types of wires. The first is to carry current, the second is to make the circuit complete, and the third is the grounding wire. These wires have different specification numbers, sizes and codes. The codes marked on them tell us their insulation and electrical capabilities. If the cable you use is marked "G", use a ground wire. One common example of this type of cable is the use 12 – 3/g cable. Cables usually have nm-b, BX and uf-b sheaths. They can be roughly divided into two types according to their conductors. The first is a two core cable, and the second is a three core cableNowadays, like everything else, wires and cables can also be purchased online. Many suppliers on the Internet are committed to providing all types of wires and electrical equipment online at a cost-effective price.

IATF (International Automotive Task Force) is a specialized organization established in 1996 by the world's major auto manufacturers and associations.   In order to harmonize the international automotive quality system specifications, a specialized agency was established in 1996 by the world's major automobile manufacturers and associations, called the International Automotive Task Force (IATF). IATF members include the International Organization for Standardization Quality Management and Quality Assurance Technical Committee (ISO/TC176), the Italian Automobile Industry Association (ANFIA), the French Automobile Manufacturers Committee (CCFA) and the Automobile Equipment Industry Federation (FIEV), the German Automobile Industry Association (VDA), car manufacturers such as BMW, Chrysler, Fiat, Ford, General Motors, Renault and Volkswagen, among others.

On December 24, Xiaomi Auto's Weibo account and video number were launched one after another. Yesterday evening, Lei Jun, as the founder of Xiaomi, also posted @mi car on his personal micro blog. This series of operations has also made many industry insiders speculate that millet cars will have major news.   On December 26, Xiaomi's official microblog and Lei Jun's microblog simultaneously issued a statement saying: A technical conference will be held at 2 PM on December 28. At the same time, it is also accompanied by a publicity picture on the theme of "crossing". From the picture, it can be seen that the background of the publicity picture is the overhead perspective view of the millet car, and the design details of the front suspension, balance bar, anti-tilt bar, front spare car, and front motor can be clearly seen in the picture. For the hidden intelligence of this propaganda picture, it has also attracted many netizens' speculation, and some netizens have marked out the details of the poster.   Some automotive media comments said: this configuration of the Xiaomi car can not be sold at a very low price. Some digital bloggers also participated in the comments that the cabin floor beam arrangement, the battery should use CTP or CTB technology, from the tire texture, like Michelin PSEV, the front suspension front double fork arm, the rear probability is five linkages, and from the organ accelerator pedal point of view, the positioning is more sports. In this way, the cost of SU7 is indeed higher.   For the arrival of Xiaomi cars, Lei Jun said in his personal microblog today that it has been 1000 days since Xiaomi's official propaganda car was made, and many people asked "how is Xiaomi making cars so slow", and friends said, "I heard that electric cars are easy to make, and small companies with two or three hundred people can make cars in less than two years." In response to the slow building of Xiaomi cars, Lei Jun responded in the article: Today's automobile industry, it is not difficult to save a car. Just get a car, reverse engineer it, change the look, and we'll be done in no time. But with 200 new cars released every year on the market today, does Xiaomi need to save another one? Therefore, when the Xiaomi car team was just formed, we had a meeting for three days and three nights, and only discussed a simple question: to join Xiaomi, what kind of car do you want to build? Later, all the staff agreed: there is no shortcut to building a car. Adhere to the forward development, starting from the underlying core technology, ten times investment, build a good car! These technologies will also be fully displayed to everyone at the Xiaomi Car technology conference on December 28. Regarding the content of the Xiaomi automobile technology conference on December 28, Lei Jun also revealed on Weibo that this time, only the technology is issued, not the product.   It is worth noting that since Lei Jun announced the construction of c...

With the rapid development of new energy automobile industry, new energy wiring harnesses get development opportunities. The difference between a high-voltage wire harness and a low-voltage wire harness is that the high-voltage terminal tends to generate heat due to the high current passing through the terminal. As a result, the mechanical strength of the terminal and the insulation performance of the wire harness are decreased, and the oxidation of the conductor further aggravates the heating.   High voltage terminal crimping needs to consider both the reliability of the crimp and the low temperature rise of the crimp. High voltage terminals are commonly crimped Crimping, resistance welding, high frequency welding Crimping uses crimping equipment and dies to join wires and terminals together through a crimping process. High frequency welding is the use of high frequency welding machine to weld wire and terminal together. Resistance welding is the use of special resistance welding equipment to connect the wire and terminal together. Advantage Simple operation, convenient maintenance, low manufacturing cost, high operating efficiency, suitable for mass production. Shortcomings The wiring harnesses and terminals that require high current pass rate and low resistance after the connectors are connected cannot be met. Figure 1 shows the common crimping modes of large square high voltage terminals, which are hexagonal closed terminals. The advantages of ordinary crimping are obvious, but how to make ordinary crimping develop advantages and avoid disadvantages, as far as possible to reduce the resistance is particularly important. Reducing resistance means reducing heat, reducing product temperature rise, making product life and quality better.   Hazard of terminal heating After the terminal is heated, it is easy to oxidize itself and the contact surface of the conductor of the wire, generating oxide film, so that the contact resistance increases, and the increasing speed increases exponentially with the increase of temperature, further increasing the terminal temperature rise speed, and serious fire will be caused. At the same time, the elastic element of the contact structure will be annealed, the contact pressure will be reduced, and the contact resistance will be increased further. In addition, the heating will make the wire insulation layer connected to the terminal aging brittle, resulting in a decline in insulation performance, there is the risk of leakage overheating caused by fire.   As shown in Figure 2, the high voltage wiring harness has three heat sources. Terminal three heat source : Conductor Conductor: The conductor itself has a resistance. The smaller the cross-sectional area, the higher the resistance. Resistance will cause heating. Terminal compaction: insufficient compression ratio will make the conductor loose, resulting in large resistance, easy to heat. Excessive crimping is easy to cause small cross-sectional area,...

Solution 1:   According to the wiring harness configuration list of the vehicle and the wiring harness direction in the 3D wiring diagram, the measurement tools in CATIA are used to measure the required sizes of each trunk, branch, buckle, cable tie and rubber parts according to the drawing requirements of the wiring harness diagram. The 2D diagram can be arranged through reasonable design, and the outline of the wiring harness diagram can be basically determined.     Solution 2: In the process of automobile circuit design, in order to understand the actual situation of automobile electrical equipment in detail and facilitate the arrangement and connection of automobile circuit, engineers need to rely on the schematic diagram, automobile circuit diagram and application diagram. Although the diagram reflects the actual installation position of the electrical equipment on the vehicle, the criss-cross wires in the diagram increase the difficulty of reading the diagram. In order to make the circuit diagram more close to the reality, it is often necessary to draw the wiring harness installation diagram. Wiring harness diagram is the whole car circuit diagram drawn according to the actual installation position of electrical equipment on the car, mainly based on the formation of wiring harness, the drawing surface of the line is less, the expression of the connection between the components has become its main content, in order to express the color of the wire, the terminal code of the joint, often supplemented with wiring harness grouping and terminal number table and wiring harness terminal wiring table. The contents of the wiring harness First, the composition of the wire harness The automobile wiring harness diagram is composed of multiple wiring harnesses, including main line harnesses and branch wiring harnesses. The diagram should show the composition of each wire harness, how many branches there are on each harness, how many wires there are on each branch, the color of the wire and what the stripes are. Two, the length of the wire harness The length of the wire harness includes the total length of the wire harness, the length of each branch and the length of the interval between two wire ends. Three, connection code and connection mark The number of electric appliances on the car is large and complex, in order to make the connection correct, each connection point should be marked with connection code and connection mark, so as to facilitate the connection. Four, the adapter Because there are multiple wiring harnesses, wiring harnesses and wiring harnesses, branches and wiring harnesses, or branches and electrical appliances are all connected through the connector, it should be indicated how many wires on each connector, where each wire is located in the wiring hole of the connector, what kind of shape of the connector, whether the adjacent several connectors are easy to be confused. Color of wire In order to make you understand the...

The development direction of automotive wiring harness   Competition among wire harness manufacturers has intensified. Product development to a certain period, competitors will also have scale, strength, integrity of the enterprise to compete. Smaller companies will be weeded out. Wiring harness assembly is increasingly concentrated in technologically capable enterprises.     Because the automotive wiring harness is different from the general wiring harness, there are some electronic components attached to the car wiring harness, such as sensors, thick film circuit mixed, such electronic components have high technical content, emphasizing the technical safety and reliability; Has gone beyond simple, generic assembly. It is reported that a mid-range car, there are nearly a thousand interface, more than 30 microprocessors, hundreds of pairs of connectors, the total length of wire used is 1500m-2000m. With the development of IT technology and the emergence of E concept car, put forward the development direction of automobile network, modular, network cluster has been ready to appear, so that the wiring harness manufacturing technology will appear a second leap. The function of wire harness extends from ordinary signal transmission to data transmission.     In addition, the limitations of wire transmission signal, the extensive use of fiber optic cable, automotive wiring harness manufacturing technology for the third leap, cable with transmission speed, large capacity, small volume, strong confidentiality, anti-interference advantages of the good, will soon be a thing of the future automobile data processing and exchange of important material optimization, the power and signal distribution system into a new stage of historical development. Fiber-optic cables are already being used in BMW's D-Class cars, and the Japanese are following suit. The main development trends of wire harness technology are as follows:   1.Multi-channel transmission technology: The technology refers to the transmission of multiple signals over a common media, make the electronic controller can share information, avoids a single connection, the application of this new technology, make the wire connection to simplify, compact structure, can reduce weight, also can reduce the cost, because the information is widely Shared, rather than simply copying, therefore, for fault diagnosis, more accurate, Engineering changes are faster and defects are more easily repaired.   2. Multi-station connection technology: the technology refers to the internal connection system can connect multiple intelligent devices, it can not only share battery energy, reliable grounding, more importantly, it can share data, the technology greatly reduces the input and output of the module, the number of counts, simplify the module and wiring harness assembly; Due to the reduction of a large number of contact points, production cycle, production costs will be s...
