The magnetic holding relay is a common type of relay, and it is also a new type of relay. In recent years, the development speed is fast and the usage rate is high. This automatic switch, like other electromagnetic relays, plays an automatic role on the circuit. Switch on and off. The difference is that the normally closed or normally open state of the magnetic holding relay is completely dependent on the permanent magnet, and the switching of the switching state is accomplished by triggering a pulsed electrical signal of a certain width.
WENZHOU NCR INDUSTRIAL CO.,LTD. is one of the core manufacturing companies of NCR Group. The magnetic holding relay developed by the company includes a base, a magnetic circuit part, a moving piece combination and a static combination. The magnetic circuit part and the base are connected by a push piece; The road part is composed of a coil frame, an armature assembly, a yoke iron, a iron core, a plastic splint and an excitation coil. The armature assembly is composed of a magnetic steel, a pole piece and a magnetic package insulator, and the pole piece, the yoke and the iron core in the armature assembly are formed in cross contact. Closing the magnetic circuit; the moving piece assembly comprises a connecting piece, a moving reed, a large split piece, a small splitter piece and a moving contact, the static piece assembly is composed of a static piece and a static contact, and the plastic clamping plate is provided with a hole, and the coil frame is arranged There are two lead legs, the inner and outer lead wires of the excitation coil are respectively soldered on the lead pins, the moving springs on the movable piece assembly pass through the holes at the front end of the push piece, and the protruding portion on the armature assembly passes through the hole at the rear end of the push piece, magnetic The wiring legs of the road part are connected to the positive and negative poles of the DC power supply.
Conventional magnetic holding relays have low sensitivity and require a large coil drive power when the contact assembly is closed.
