Automotive wire harness processing is developing towards intelligence and high speed, new energy vehicles have become the inevitable trend of automotive development. In 2022, the global sales of new energy passenger vehicles exceeded 10 million for the first time, reaching 10.824 million, an increase of 61.6% over the same period last year. Among them, 6.884 million new energy vehicles were sold in China, and the market share (40.5% in 2020 and 51% in 2021) increased to 63.6%, maintaining the first place in the world for eight consecutive years. At the same time, the development of more subversive intelligent connected cars is also accelerating, and Internet giants and other emerging participants are actively pouring into the market. There is no doubt that new energy and intelligent connected cars have become the mainstream of the automotive industry, and the demand for suitable wire harness will also increase greatly.
The automotive wire harness is the network main body of the automotive circuit, and it is the connection component of the automobile electrical system, which is used to transmit signals or electric power. The operating conditions and parameters of the car are directly reflected on the on-board computer through the wire harness, so it has always been called the "nervous system" of the car. The electronic technology content of automotive wire harness has gradually become an important index to evaluate automotive performance.
Compared with traditional vehicles, the electronic system of new energy vehicles has more stringent requirements in physics and performance. Taking the automotive connector and wire harness subdivision industry in the automotive electronics industry as an example, the automotive connector and wire harness are the key components for signal transmission in the automotive electronic system. It organically connects the vehicle central control unit, the automobile control unit, the electrical and electronic execution unit and the electrical devices. Generally speaking, the consumption of traditional automotive wire harness and connector is about 200and 350respectively, and the value of bicycle connector and wire harness is about 3000-5000 RMB. However, with the development of automotive electronics, intelligence, networking and new energy, the value of bicycle connectors and wire harness will be raised to 20000 RMB, indicating that the automotive electronic connector and wire harness industry has a broader space for development.
In addition, the electronic equipment of new energy vehicles is more complex and needs more comprehensive and powerful wire harness functions to meet. The requirements of new energy vehicle wiring harness are quite different from those of traditional automobile wiring harness. First, the new energy vehicle wire harness works in a high-current, high-voltage environment, which can easily lead to wire harness heating, so the wire harness needs to be designed thicker to facilitate heat dissipation. Second, because the motor of the new energy vehicle is generally installed in the front position, and the battery is generally installed in the rear position of the car, for the safety of the car, the wire harness can not be placed in the car like the traditional car, but the wiring outside the car is required. Therefore, its mechanical protection is very important, such as moisture, moisture and so on.
Third, because the motors of new energy vehicles all use alternating current, the interference is very serious, so the wire harness is required to shield interference and have good tightness.
Wire harness production and processing itself is a labor-intensive industry, with the changes in the labor market, labor costs begin to become higher and higher, forcing enterprises to increase production costs. In the face of the new demand of new energy automobile wiring harness, it is bound to trigger a technological revolution in the wire harness processing industry. JMK intelligent automatic terminal pressing machine, the front end of the wire cutting, peeling and pressing process is completed by the machine automatically, saving labor costs, each processing process has quality monitoring, terminal crimping force monitoring, CCD visual inspection, etc., to ensure the separation of good and defective products.
