Working Principle
The 4mm Bullet Connector Set operates using a mechanical plug-and-socket electrical connection. The male connector features a spring-contact bullet pin, while the female connector has a matching cylindrical socket.
When the male bullet connector is inserted into the female socket, the spring-contact structure creates pressure between the metal contact surfaces. This establishes a secure electrical path with low contact resistance, allowing current to flow through the connected wires.
The gold-plated brass contacts help maintain electrical conductivity and resist surface corrosion. The connectors can be disconnected when required, making them suitable for modular power connections, RC motor wiring, battery connections, and equipment maintenance.
