42949-2

The 42949-2 application field and working principle involve a range of quick connects and quick disconnect connectors that rely on non-structural features to make electrical connections. These quick connectors, also referred to as quick connects, provide fast and reliable electrical connections when designed to meet industrial requirements. They are designed to be easily connected and disconnected from the corresponding connector without making structural changes.

Quick connectors are primarily used in telecommunications, military, industrial, and electrical applications where reliability and safety are critical. The most commonly used quick connectors are the connectors that are designed according to the German industrial standard, DIN 42949-2. These connectors are designed for applications requiring high levels of vibration and EMC compatibility.

The 42949-2 standard specifies the connectors with the dimensional and electrical performance characteristics most suitable for quick connect and disconnect mating connections including vibration, temperature, current and voltage, and temperature cycling. The connectors are manufactured from materials specified in the same specification that are suitable for an ambient temperature range from -55°C to +85°C.

The 42949-2 application field and working principle is based on the use of a non-structural feature called an electrical stop. The electrical stop positively locks the mating parts together and prevents accidental disconnection. This prevents any electrical contact or arcing from occurring between the mating parts. The electrical stop ensures the electrical connection between male and female connectors.

The 42949-2 application field also includes applications such as data telecommunications, power generation, lighting, aviation, and industrial power. These applications demand the connectors to be able to withstand vibration and environmental conditions while providing fast and reliable connection and disconnection. The quick connectors can be used for both high voltage and low voltage applications.

The working principle of the connectors is based on the use of spring-loaded contact pins that form an electrical connection between a male and female connector when the connection is made. The pins are designed to fit into special pockets in the female connector, thus forming a secure fit and preventing it from slipping out of the socket. The connection is further enhanced by the use of electrical insulation between the contact points.

When the connection is made, the electrical energy can be transferred through the contact pins and the electrical insulation, thus providing a reliable connection. This ensures that no current leakage occurs during the connection or disconnection. The pins are also design to prevent any over-voltage, over-current or short-circuit damages.

In conclusion, the 42949-2 application field and working principle are based on the use of non-structural features and materials specified in the DIN 42949-2 to make electrical connections. The connectors are designed to provide fast and reliable electrical connections while providing protection against vibration, temperature, current, and voltage. They can be used for both high voltage and low voltage applications, and are trusted for their reliability in critical applications.
