How to choose a qualified waterproof connector

-

The first is heat resistance, and the waterproof connector has good adaptability at both high and low temperatures. The maximum temperature can reach 200 °C (except for a few high temperature special waterproof connectors) and the minimum temperature can be as low as -65 °C. Due to the resistance, the device generates a lot of heat under electric working conditions and the device heats up. So the temperature we usually refer to consists of ambient temperature and contact temperature.

The second is that the waterproof connector can effectively adapt to the salt spray resistant environment. Generally structural metals, the contact surface may have electrochemical corrosion. We cannot avoid the salty and wet working environment. However, the performance of the waterproof connector can be improved to prevent the device from being corroded, and the performance of the connector is generally tested by a salt spray test. A certain concentration of NACL is used to compress the air to create a salt spray atmosphere. The general waterproof connector can last up to 48 hours.
The third is the shock resistance and impact resistance of the waterproof connector. These two parameters are particularly important in special environments such as aerospace, aerospace, rail and road transport. It is also a measuring rod for strong and electrical contact. In the impact test, the peak acceleration, duration and shock pulsation waveform and the time the electrical connection was interrupted.
The fourth is the humidity of the environment. The standard requirements for waterproof connectors for power supplies must be strict, as the humidity of an environment may affect the waterproof connector. Therefore, it is necessary to check the temperature resistance of the waterproof connector. Electrical performance is the basic performance of waterproof connectors, and mechanical performance is one of the important indicators of the life of waterproof connectors.

  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

In the context of global environmental conservation, new energy vehicles have become an inevitable trend in the development of automobiles worldwide. PwC's first blueprint for the Chinese auto industry, released on December 8, states that China's new energy vehicle sales are far ahead of other markets in the world. With the government's vigorous support for new energy vehicles, China's new energy vehicle era has arrived. Global sales of new energy vehicles reached 500,000 in 2015, of which 330,000 were sold in China, three times the previous year, and far ahead of other markets in the world. Accelerating development, Internet giants and other emerging players are actively entering the market, bringing pressure and shock to traditional car manufacturers and dealers. There is no doubt that new energy and intelligent connected cars have become the mainstream of the automotive industry, and the demand for applicable wiring harnesses will also increase significantly.
