The automotive field is the largest market for connectors, and automotive connectors account for 23.70% of the global connector industry. From the perspective of automobile, the largest segment of connector application, new energy vehicles are the biggest bright spot. Restricted by issues such as technology, safety, and standard certification, traditional automotive adapter connectors have always been controlled by foreign high-end companies, and Chinese connector companies have high barriers to entering the traditional automotive field. With the rise of new energy vehicles, Chinese connector companies have successfully entered the new energy vehicle industry chain. The Chinese brand of new energy vehicles has occupied the main market in China, and the Chinese connector company AVIC Optoelectronics has successfully supplied Tesla, JAC, BYD and other new energy vehicles. There are nearly 100 types of electronic connectors used in traditional cars, and about 600 connectors are used in a single model, which are mainly used in engine management systems, safety systems, and entertainment systems. Compared with traditional fuel vehicles, the demand for connectors for new energy vehicles has increased significantly. The value of low-voltage connectors used in traditional fuel vehicles and bicycles is about 1,000 yuan, while the performance indicators such as material cost shielding and flame retardant requirements of high-voltage connectors are higher than those of traditional low-voltage connectors. The value of connectors used in new energy vehicles and bicycles is much higher. for low voltage connectors. Among them, the value range of connectors for pure electric passenger vehicles and bicycles is 3,000-5,000 yuan, and the value range of connectors for pure electric commercial vehicles and bicycles is 8,000-10,000 yuan. There are various ways of connecting new energy vehicle connectors, which are basically divided into two types: connectors (connected with cables) and connectors (connected with printed circuit boards). Crimp and press-in are the most common connection methods of the two. This means that the Chinese for these two connection methods can be expressed by the word crimp. The definition of a press-fit connector is to press the external force of a pin (also called a terminal) into a hole that is smaller than the thickness. Because of the low cost, high efficiency, simple operation, high reliability, communication and computer industries related to SMT (that is, surface mount technology is a connection technology). Electroplating plugs (terminals) and injection (rubber shells) have two connection methods: independent plugs and combination plugs. In the connection method, manufacturers usually require all plugs to be checked for missing and accurate positioning during the assembly stage. In addition, the normal testing and stamping stage, the assembly of the connector also challenges the test speed of the automatic test system. Most assembly lines shoot once or twice a second, but for each connector passing through the camera, the vision system often needs to complete many different inspection items. Therefore, the detection speed becomes an important performance index of the system. Actual position refers to the distance from the front end of each plug to the specified design reference line. The visual inspection process system must be the inspection of the correct position, which is another requirement for the inspection system of the connector assembly. Make this imaginary standard line in the inspection picture, measure the actual position of the front end of each plug, and judge whether it meets the quality standard. The standard points that delineate this standard line are often not seen in the actual connector or appear on other planes, and the same lens is not visible at the same time. In some cases, the plastic of the connector housing must be ground to replace the location of this reference line. The lithium battery used in new energy vehicles has a large capacity, which can last for 400 kilometers under conditions, the power consumption of 100 kilometers is 14 kilometers, the calculated charge is 56 kilometers, and the weight is 350-400 kilometers. Its working voltage range has risen sharply from 14v of traditional automobiles to 400kwh, so new energy vehicle connectors provide high-voltage connectors, which are the heaviest V connectors of new energy vehicles, and require corresponding high-voltage connectors. With the improvement of automobile intelligence, in addition to the traditional engine management system and other devices that require connectors to connect data, more and more advanced in-vehicle entertainment systems, intelligent driving systems, etc., have an increasingly strong demand for connectors.
