At present, new energy vehicles are developing in the direction of intelligence, and the intelligent driving system continues to stack up to L3, increasing the number of sensors (such as cameras, millimeter wave radar, and LiDAR), as well as the expansion of functional requirements such as parking assistance, lane departure warning, night vision assistance, adaptive cruise control, collision avoidance, blind spot detection, and driver fatigue detection, prompting ADAS (Advanced Assisted Driving) to be equipped with a higher bandwidth transmission network. The main function of automotive connectors is to achieve connections when circuits are different or isolated, which is essential for mobile cars. Today, our topic of high-speed connectors in the new energy vehicle supply chain can be divided into Fakra, Mini Fakra (HFM), HSD, and Ethernet connectors.
The high-speed connector commonly used in traditional passenger cars is the Fakra, which is generally used for the installation and connection of sensors; Mini-FAKRA, due to its excellent integration performance, serves as a transmission intermediary between sensor data and AVM systems; HSD is mainly used for high-speed transmission from AVM to the host end and from the host end to the cockpit end; On board Ethernet serves as the backbone network for communication within the vehicle, connecting various subsystems within the vehicle. However, Fakra has a small data transmission volume, a large volume of structural components, and cannot meet the current mainstream architecture interface protocols. The currently developed HFM can meet all the requirements of sensors such as cameras and radars required for ADAS, high-resolution displays required for infotainment systems, and V2X antennas required for vehicle networking. At the same time, it can achieve a volume reduction of 80% and a significant increase in data transmission. With the acceleration of the process of vehicle networking, The significant increase in the usage of high-speed connectors for bicycles is expected to lead to a wave of replacement for traditional FAKRA by Mini FAKAR in the coming years. And HSD is used in conjunction with HFM, such as the camera transmitting the collected data to the vehicle's surrounding system through HFM, and then the HSD transmitting the data to the host. Therefore, the vehicle only needs to achieve multiple intelligent requirements, requiring the use of multiple connecting devices, including waterproof Fakra, HFM, and HSD.
Market barriers for high-speed connectors
At present, the high-speed connector market is mainly controlled by countries such as Europe, America, and Japan. International manufacturers have entered the connector market earlier and have formed rich technical reserves in the connector field. And connector products have commonality in underlying principles, so manufacturers' development experience in other fields can be referenced and applied to the field of automotive connectors. Due to its early entry into the industry, rich technological accumulation, and stable customer relationships with various industries, the industry entry threshold for automotive high-speed connectors is relatively high, mainly reflected in the following aspects:
technical barriers
High speed connectors have rich technological accumulation and inherent advantages, which are reflected in their ability to quickly develop and produce molds, as well as their leading technological level and rich testing experience, which will directly affect the stability of product quality and supply speed, ultimately affecting product costs. High speed response to downstream customer needs has also become one of the necessary conditions for micro electrical connector enterprises.
Financial barriers
The individual value of connectors is not high, but the development of connectors involves research and development, mold design and development, production and manufacturing, and the equipment is relatively expensive. Some equipment has a unit price of over one million, so it is necessary to have large-scale production and strong financial scale investment to have significant advantages. Therefore, the industry has high industry barriers.
Long validation cycle and strict standards
Passenger cars belong to durable goods, so the requirements for the quality and stability of components are relatively strict. Generally, the life cycle of the power platform of vehicle manufacturers is 5-7 years, while vehicle manufacturers have established a relatively complete quality evaluation and certification system internally. From product certification to bulk supply, the entire process generally takes 1-2 years.
"connector", "terminal block", and "connector" are different forms of application that belong to the same concept, and are commonly referred to according to different practical applications.
Terminal refers to a type of connecting component in electronic and electrical components, which connects conductors to receiving terminals in equipment or cables. Usually includes a set of metal bars that can provide wire connections for input, output, power, and ground. Due to its crucial role in circuit connections, it has a wide range of applications.
Connectors are important components in electronic devices, mainly used to connect different parts of electronic devices. Its working principle is to connect the wires in two electronic devices together, allowing electrons in the electronic devices to circulate between the two devices.
The connector is a component that our electronic engineering technicians often come into contact with; Its function is very simple: to establish a communication bridge between blocked or isolated circuits in the circuit, allowing current to flow and enabling the circuit to achieve its intended function.
