Description
Technical field
The present invention relates to a kind of DPDT (double-pole-double-throw, DPDT) electromechanical relay.
Background technology
Relay is the electric mechanical switch by signal of telecommunication control.A typical relay is made up of an electromagnet and soft iron shell fragment.The movably spot welding contact of generally ining succession on the shell fragment, shell fragment itself is fastened by spring.After relay was switched on, electromagnet can produce active force to the soft iron shell fragment, and makes it overcome spring force, went to close or open an electric loop thereby move the spot welding contact.After the electromagnet outage, the spot welding contact bounces back into the origin-location.Relay has various dissimilar, many contact types, closed type are arranged, has built-in delay circuit type, as the many contact-types of multistep that use in the early stage telephonic communication circuit, also has the lockable type.
Relay can also and be thrown number and classify according to its number of poles that has.The magnetic pole of relay is meant the common terminal in each path.And each position that magnetic pole can connect is called and throws.Relay can have n magnetic pole and m and throw.For example, (single-pole-double-throw, SPDT) relay has a magnetic pole and two and throws single pole double throw.Double (DPDT) relay has two magnetic poles, and each magnetic pole has two controlled throwing of while.
Relay can also be classified according to its form.The classification of relay form is to carry out according to the utmost point of relay and the number of throwing and the default location of relay.Relay has three kinds of form: A, B and C usually.Form A has the single pole single throw relay of often opening default conditions.Form B is the single pole single throw relay with normally closed default conditions.The single pole double throw relay of form C for having no progeny and meet (break-before-make) earlier.
Lockable type relay is meant after electromagnet outage, and one type of relay with open mode can keep shut.The conversion of opening and closing between the two states realizes by giving the of short duration current impulse of electromagnet.A significant advantage of lockable type relay is to have no power consumption (in fact, this relay is not need power supply) at non-on off state.
United States Patent (USP) announces the 7th, 482, has disclosed a kind of novel electromechanical formula relay with movable first magnet and contiguous the 3rd magnet for 899B2 number.Movable first magnet is permanent magnetization and has first end and second end.After the 3rd magnet energising, three magnetic field (converts magnetic field) vertical with the first magnet magnetization direction is provided, and produces on first magnet that a magnetic torque makes the rotation of first magnet and in circuit of its first end closure.After change loads on the sense of current of the 3rd magnet, can change the direction of the 3rd magnetic field (converts magnetic field), and cause putting on the change of the magnetic torque direction on first magnet thus.Therefore, first magnet can rotate breaking off the circuit at its first end place in opposite direction, and the closed circuit that is positioned at its second end place.This electromechanical relay also has makes first magnet remain in second magnet of a certain fixed position.
