The 189848-1 application field is a standard for the design of automotive electric connectors. It specifies the requirements for the design of interconnecting systems connecting cars with other vehicles, as well as with external sources of power.

The 189848-1 standard was first published in year 2002 and is jointly published by the European Automotive Manufacturers Association (EAMA) and the European End-Application Technology Cooperation (EETC). Its applicability covers use in passenger vehicles, commercial vehicles and off-highway vehicles.

The 189848-1 standard specifies the requirements for the design of the necessary interconnecting systems and connectors. The basic requirements include maximum working voltage and maximum current carrying capability, magnetic interference and environmental testing. The standard defines the various methods and tests used to qualify the connection system operation. For example, pull out strength tests, temperature cycle tests and contact resistance tests are specified. The end products should comply with the requirements of the standard in order to be considered acceptable.

The 189848-1 standard has two basic components. The first is referred to as the Basic Interconnecting System (BIS) which consists of a male and female connector, a socket or inlet, and an internal power electronic circuit. The second component is the Host Component (HC), which is a process for connecting end-user electrical equipment.

The working principle of the 189848-1 application field is based on the principle of electrical interconnections. This standard defines various factors such as wire size, cable type, required force to make a connection and so forth. It also defines the necessary testing procedure to ensure that all components interconnected will have the expected performance according to the specified requirements. Further, it also specifies the necessary steps to be taken for mitigating risk factors such as overheating, fire hazard, etc.

In the 189848-1 standard, the system as a whole is tested to determine conformity. This is done during type or product testing, verifying that the entire system can operate safely in normal conditions. All parts that make up the system are tested to determine their specific characteristics, and additionally the entire system is tested to ensure it is working correctly. This process makes sure no single part of the system is causing faults that could lead to danger in the future.

The 189848-1 standard also specifies the necessary safety requirements for use. This includes the protection requirements for use in electrical installations, safety hazards identification, and additional certification requirements.

In conclusion, the 189848-1 application field and working principle is a very important standard. It provides a systematic approach to developing interconnecting systems and connectors for automotive vehicles. The standard outlines the various requirements for selecting components that are appropriate for the application, as well as the necessary procedures for testing, evaluating and verifying the system. It is essential that all automotive vehicles conform to the 189848-1 standard in order to ensure safety, performance and reliability.
