Description

Contactor {magnetcontact}

Some of the electrical appliances, controls, and equipment that are hard to operate by hand are connected to the output contacts of relays or magnets electrically connected to the input contacts and operate by outputting electricity through their operation.

A load is connected to the output contact of a relay or magnet having an input / output contact with an electromagnet, and electric power is applied to the electromagnet to connect the input / output contact to the output contact. .

However, due to the operation of the electromagnet, the maintenance of the contact connection causes problems such as chute ring, electromagnetic wave generation, change of the holding due to change of input electric power, heat generation,

For example, semiconductors and other facilities have hundreds of billions of won, and news stories that require hundreds of billions of won in order to initialize the system during a 0.5 second power outage.

Patent Document 0268602 discloses that the movable contact is connected to the fixed contact by the operation of the electromagnet and the fixed key of the fixed portion of the fixed portion of the spring is inserted and fixed horizontally in the groove of the protrusion of the movable portion so that the contact connection is maintained without electricity consumption of the electromagnet .

However, there is a disadvantage that the fixed key is momentarily right-angled by the action of the spring on the protrusion of the protrusion of the moving part of the decimal point which moves very quickly, and the operation of the proportional insertion is malfunctioning. This is because the connection of the contact points must be secured, so that there is no clearance between the tight grooves to prevent retraction of the projections and the fixed key inserted into the grooves. There was a disadvantage that this recovery and proportional insertion malfunctioned.

A convenient application 1020100022560 has a plurality of ball bearings for hanging and fixing frame articles and the like, which are improved, and a one-way wire having a spring, which is always contacted and fixed to the projection of the movable part.
