The development trend of high-voltage connectors

The development trend of high-voltage connectors

1  Policy-oriented role

The formulation of the country’s new energy electric vehicle industry policy should be determined in accordance with China’s national conditions. Regarding the development of a green transportation system, the national plan proposes to accelerate the upgrading of vehicle and ship structure and promote the use of new energy vehicles. By 2020, the production and sales of new energy vehicles will reach about 2 million. Accelerate the use of new energy or clean energy vehicles in new and updated public transportation, sanitation, postal, rental, commuting, and light material distribution vehicles in urban built-up areas, and the use of key areas will reach 80%; key areas of ports, airports, railway freight yards, etc. The addition or replacement of work vehicles mainly uses new energy or clean energy vehicles.

Before the end of 2020, all buses in logistics parks, industrial parks, industrial parks, and large-scale separate cities will be replaced with new energy vehicles. Build centralized charging piles and fast charging piles in logistics distribution centers such as logistics parks, industrial parks, industrial parks, large commercial shopping centers, and agricultural wholesale markets. According to the country’s policy orientation, automakers also adjust their internal models in accordance with relevant policies, which determines the development direction of the connector.

2 Platformization and customization

There are also many types of electric vehicles, such as passenger cars, logistics vehicles, including custom connectors. The requirements will be different, or some special requirements will be put forward, so they include unmanned driving, Internet of Things vehicles, New energy, etc., our connector manufacturers should consider, this kind of customization of electric vehicle industry needs (vehicle end and battery end), I think it may be a good choice, we are now moving towards first step. Because in general, these types of cars will be used in different occasions. In fact, they are all subdivisions. Although the volume is not that large, the market belongs to us. We are top-notch in this market. This is also a Good choice.

The second is platformization. In the future, batteries and vehicles will become platform-based. How to maintain in-depth technical communication with customers and form a platform-based product for both parties is very important. There are more domestic OEMs, and everyone’s platforms are different now, such as batteries. There are a lot of whole package factories, and each has its own module solution and battery box group solution. As a connector manufacturer, you need to think about how to make platform-oriented applications.

3 Miniaturization and lightweight

Under the background of the auto industry’s increasing pursuit of energy saving and environmental protection, the lightweight and miniaturization of automobiles has become a technological trend, and it is also the focus of auto manufacturers’ technical competition. By controlling the weight of the entire vehicle, it can effectively reduce fuel consumption, reduce exhaust emissions, and increase fuel consumption. efficiency. In a big environment like the automobile industry, the new energy connector must also be miniaturized and lightweight.

A series of important solutions for the miniaturization and lightweight of automobiles, including the introduction of smaller-sized high-performance copper alloy wires as signal transmission lines, and the introduction of terminals and contact systems that are developing towards miniaturization, as well as the crimping produced by this miniaturization Unstable optimization and reliable verification methods; the principle of using high-performance terminals to reduce the size of low-power transmission wires, and the use of aluminum wires instead of large-diameter copper wires that transmit higher power.
