product structure
Infinite relay is the typical structure of AX series relay, which is composed of electromagnetic system and contact system. The electromagnetic system includes coils, iron cores, vehicle irons and armatures. The coil is installed horizontally on the iron core, and is divided into a front coil and a back coil. The use of dual coils is to enhance the flexibility and flexibility of the control circuit, which can be controlled by a single coil or a series of double coils according to the circuit needs. The armature is fixed on the blade of the yoke by a butterfly-shaped steel wire, which is flexible in movement. There is a heavy hammer in the transmission part of the Yantie to ensure that the relay armature returns reliably by gravity. The number of weights installed is determined by the structure of the relay contact system, and should be able to ensure the reliable release of the relay. A stop piece is installed at the closed position of the armature and the iron core to ensure the minimum air gap of the magnetic circuit of the relay, prevent the ferromagnetic parts of the magnetic circuit from magnetizing, and ensure that the relay falls reliably. The iron core, vehicle iron and armature of the relay are made of electromagnetic pure iron, which has high magnetic permeability and small remanence.
