Terminal plating is to ensure reliable use of the connector

-
As electronic products become more lightweight and more sophisticated, there is a higher mandate for electronic connectors, such as high reliability, smaller size, and higher transmission performance. The most common place in electronic connectors was the circuit, the board-to-board connectors used on the board, the wire-to-wire or wire-to-board connectors on the wire harness, and now many industries require connectors, such as electronic equipment, automobiles, aviation, etc.
​Terminal plating is to ensure reliable use of the connector
The most important part of the electronic connector is naturally the terminal of the contact part. The materials of these terminals are mostly not the same, because the nature and function of the places used are different, so the materials will be different, some need metal, some need liquid, the material is determined according to the specific conditions. 
The choice of the electronic connector terminal plating is mainly considering the use environment, which is mainly divided into three cases: for general applications, tin plating is the most common because tin is relatively cheap. However, the texture of tin is relatively soft, the number of insertions and removals is generally low, and it can only play a simple protective anti-corrosion effect. For connectors with more of plugging and unplugging, gold plating is generally required. Tinned connectors have a lower operating temperature, brass or bronze tin plating can be operated at 110℃, and steel tin can reach 190℃. For higher operating temperatures, other coatings are required, such as copper nickel plating, which can be used at 340℃.

  SAE J1939 (hereinafter referred to as J1939) is the recommended standard of the American Society of Automotive Engineers (SAE). It is controlled and communicated by the "Truck and Bus Electrical & Electronics Committee" (Track & Bus Electrical & Electronics Committee). Developed and written by the Track & Bus Control and Communications Network Subcommittee. J1939 has become a recognized industry standard and choice for commercial vehicle diagnostics and data communication heavy, off-highway, truck, bus, ship propulsion, power generation, industrial pumping, construction, and material handling machinery. J1939 is a high-level protocol network (CAN) based on Controller Area. It is widely used by the diesel engine industry to provide diagnostic data such as vehicle engine speed, temperature, oil temperature, exhaust emissions, and other customizable options. J1939 connectors are divided into black and green rubber cores, but do you know the difference between t...

Benefits of overmolded connectors and wiring harnesses?

What is overmolding? In short, overmolding is an injection molding process in which two or more materials are used to combine a harness wire and a connector to form a single part, and the cable assembly is placed in a mold. In this process, the first material substrate will be covered by other materials. The overmolding process requires the use of insert molding (single injection) or multiple injection molding techniques to cover rigid plastic parts with TPU layers or other overmolding materials. So what are the benefits of the connector and harness overmolding process? Benefits of overmolding connectors and harnesses: 1. Increase the flexibility of the cable harness exit so that most of the movement between the cable harness and the connector occurs at the cable harness exit. 2. Provide abrasion resistance, impact resistance or impact resistance. 3. Fix the cable assembly by sealing the assembly in plastic. 4. Provide 360 degree strain relief and increase tension. 5. Cr...

​Cars are equipped with diagnostics tool or obd-ii ports

Modern cars have the capacity of a few computers, are tooled with software that contains millions of lines of programming code and produce gigabytes of data, but they are still different from connected cars. ​ A smart vehicle is able to optimize its performance to reduce fuel consumption, show the best path to follow taking into account current traffic and weather conditions, detect errors in the engine and collect information data to negotiate lower insurance rates. Most cars and light trucks are equipped with on-board diagnostics or an OBD II port that provides access to data from the engine control unit (ECU). To get the information you need to plug in an external device. The OBD-II specifications provide a standardized hardware interface - a female 16-pin (2x8) J1962 connector, so a single external device can be used for most car models. It also should have an Internet connection to transfer the collected data. OBD-II connects to the Internet, and generally needs to use th...
