Flexible tilt/staketail options available. 7. With wide range of terminal configurations and color-coded housing.

Application Field of 4-146311-0:

Due to its features and superior performance, 4-146311-0 rectangular connectors are typically used in wiring harness in various automotive and industrial vehicles, including buses, trucks, lifts, cranes, forklifts, generators, and ships. Additionally, this product could also be used in transportation, manufacturing and communication systems.

Working Principle of 4-146311-0:

Most modern rectangular connectors including 4-146311-0 employ a two-part female socket and a two-part male pin configuration to complete the electrical contacts. Before making a male-to-female connection, the male pin and female socket must be connected. To achieve this, the house of the female socket must be opened up to allow insertion of the male pin. After insertion, the house must be closed to lock the connection. The connection will then complete the electrical contacts. The male pin typically has three parts: compliance pins, terminal pins and contact plugs. Compliance pins are made of flexible material which can be easily deflected by internal components within the female socket. This ensures that the male pins maintain correct tension for good electrical contacts. The terminal pins form the actual contact between the male pin and the female socket. The contact plugs provide secure contact points beneath the terminal pins in the female socket. Both the male pins and female socket are constructed of special alloy materials to ensure strength and reliability. Then they are gold-plated to provide superior insulation and electric conductivity.

Conclusion:

In summary, 4-146311-0 is a rectangular connector that is widely used in automotive and industrial systems, such as buses, trucks, lifts, cranes, generators, and ships. Its features include thermoplastic material that excels in insulation, superior shock resistance and vibration characteristics, gold-plated contacts, wide range of terminal configurations and colorcoded housing. The working principle of this product involves a female socket and a male pin assembly. Compliance pins ensure correct tension for good electrical contacts, while terminal pins and contact plugs provide contacts between the male pin and female socket.
