Relay Sockets

Relay sockets, also known as SIP (single in-line package) sockets, are commonly used to provide a secure connection for power transmission between two electrical components. The 4-1904045-7 relay socket is one of the most commonly used types of relay sockets, with its application field and working principles covered in this article.

Application Field

The 4-1904045-7 relay socket is classified as a Grade I (heavy-duty) socket. It is designed for applications where a secure connection between two electrical components is required. This socket is ideal for use in elevated voltages, with high current demands and vibration-prone environments. Common applications include alternators, ignition systems, electric compressors and starter motors.

Working Principle

The 4-1904045-7 relay socket operates in an open-connection, close-connection, or floating-type connection architecture. It is a latching relay socket, meaning that when the power supply is connected, the socket remains latched or locked in the open position. This allows for consistent power transmission with minimal interruption or voltage drops. The socket also features a floating contact system, where the contacts move freely within the socket and make contact with the corresponding terminals. This design helps to reduce welding caused by static electricity or pulses, thus providing a secure connection and improved reliability.

The 4-1904045-7 relay socket includes two mounting holes for secure attachment of the socket. The mating connector, usually a plug or terminal, is then inserted to form the connection. The connection is secured by a non-metallic, two-piece contact design. The sleeve contacts the plug terminals and the actuator contacts the receptacle terminals. This combined system helps to provide a reliable connection and prevent false triggering of the relays.

Conclusion

The 4-1904045-7 relay socket is a Grade I single in-line package socket, designed for applications requiring secure connections for high voltage transmissions. Its latching design and floating contact system provide reliable power transmission with minimal interruption, and the two mounting holes provide a secure connection between the plug and the socket. With its superior performance, the 4-1904045-7 relay is an ideal choice for use in many applications.
