Abstract
The invention relates to an electromechanical relay and a method of manufacturing the electromechanical relay. The electromechanical relay and the method of manufacturing the electromechanical relay comprises movable parts in a cavity and a substrate. The cavity is formed on the substrate, is surrounded by clapboards, and is sealed by a covering layer. The movable parts comprise a first magnet which is magnetized permanently. The first magnet comprises at least one first end. When electric current passes, a switching magnet arranged nearby produces a driven magnetic field. The driven magnetic field is perpendicular to a magnetization direction of the first magnet, and produces magnetic moment effected on the first magnet. The magnetic moment drives rotation of the first magnet and the movable parts, and closes a conductive route of the first end. A change of current direction of the witching magnet changes a direction of the driven magnetic field, and changes a direction of the magnetic moment effected on the first magnet. Therefore, the first magnet and the movable parts rotate along the opposite direction, and the conductive route of the first end is opened. The first magnet can comprise multilayer magnetized layers, and a closed magnetic circuit is formed by the first magnet and other magnetic elements. Locking type and nonlocking type electromechanical relays can be formed by using a soft magnet and a hard magnet as various elements appropriately.

Technical field
The present invention relates to a kind of relay, relate in particular to a kind of electromechanical relay and manufacture method thereof.
Background technology
Relay is the electric mechanical switch by signal of telecommunication control, by the electric current in another circuit of Current Control in the circuit.Typical relay is comprised of an electromagnet and the soft iron shell fragment that is connected on the electromagnet, and this soft iron shell fragment also is called armature.The movably electrical pickoff of ining succession on the armature, described electrical pickoff remains on the normal position by spring.After relay was switched on, electromagnet can produce active force to armature, and made it overcome spring force, thereby mobile electrical pickoff goes to close or open an electric loop.After the electromagnet outage, electrical pickoff 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 refers to 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-stage is singly thrown (single-pole-single-throw, SPST) relay and is had a magnetic pole and one and throw.Single pole double throw (single-pole-double-throw, SPDT) relay has a magnetic pole and two and throws.Double-pole double-throw (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 is the single pole single throw relay of acquiescence normally open.Form B is the single pole single throw relay of acquiescence normally off.Form C is the single pole double throw relay of having no progeny first and meeting (break-before-make).
Lockable type relay refers to after electromagnet outage, can keep closing the class relay with open mode.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 without any power consumption (in fact, this kind relay is not need power supply) in inactive state.
