Problems solved by technology
However, the magnetic latching relays currently on the market often only have normally closed or normally open states.
In actual production, some production equipment has different working conditions, some working conditions require the relay to be in the normally closed state, and some working conditions require the relay to be in the normally open state. In this case, the conventional solution is to install two relays or Install a normally open contact and a normally closed contact in one relay. Installing multiple relays in the former not only takes up space, but two relays will also increase the complexity of the installed equipment structure and reduce reliability.
The latter increases the complexity of the magnetic control mechanism of the relay, which undoubtedly wastes more materials for the magnetic latching relay

The invention relates to the technical field of electromagnetic relays, in particular to a magnetic latching relay and a voltage regulating device thereof, including a housing, an on-off control mechanism, a switching mechanism and an electromagnetic control mechanism. The invention is designed with a switching mechanism, which can make the relay switch between the normally open state and the normally closed state under the condition of only one group of electromagnets. The electromagnetic control mechanism is designed, and the control center can stabilize the voltage and current to ensure the normal on-off function of the electromagnet. When the electromagnetic control center receives the protection signal, it can force the electromagnetic relay to be in the disconnected state to protect the equipment. The on-off control mechanism of the device is equipped with an arc extinguishing block, which can effectively reduce the arc generated when the high-voltage electricity is switched on and off. The buffer block is equipped with an electrostatic lead, which can guide the static electricity generated between the insulators to the shell to prevent the accumulation of static electricity. .
Description
technical field [0001] The invention relates to the technical field of electromagnetic relays, in particular to a magnetic latching relay and a voltage regulating device thereof. Background technique [0002] The magnetic latching relay is a new type of relay developed in recent years, and it is also an automatic switch. Like other electromagnetic relays, it can automatically switch on and off the circuit. The difference is that the normally closed or normally open state of the magnetic latching relay is completely dependent on the effect of the permanent magnet, and the switching state of the relay is triggered by a pulse electric signal of a certain width. However, the magnetic latching relays currently on the market often only have a normally closed or normally open state. In actual production, some production equipment has different working conditions, some working conditions require the relay to be in the normally closed state, and some working conditions require the ...
