Description

AC coil relay

Technical Field

The utility model particularly relates to an electromagnetic relay, concretely relates to alternating current coil relay.

Background

An electromagnetic relay is an electronic control device having a control system (also called an input loop) and a controlled system (also called an output loop), which is usually applied in an automatic control circuit, and which is actually an "automatic switch" that uses a smaller current and a lower voltage to control a larger current and a higher voltage. Therefore, the circuit plays the roles of automatic regulation, safety protection, circuit conversion and the like. With the development of low-voltage electrical appliances, the application of the electromagnetic relay is more and more extensive, and the requirement on the electromagnetic relay is higher and higher. The direct current coil of the small electromagnetic relay in the existing market can not completely meet the control circuits of different specifications, and if the alternating current drive relay is to be realized, the size of the relay needs to be increased, and the manufacturing cost is also increased. And the existing alternating current electromagnetic relay also has the defects of complex structure, unreliable performance and inconvenient assembly.

Disclosure of Invention

An object of the utility model is to overcome prior art's defect, provide a simple structure, stable performance are reliable, the assembly is convenient, with low costs alternating current coil relay.

For realizing the above-mentioned purpose, the utility model discloses an alternating current coil relay, including base, shell, electromagnetic component, the contact system of setting on the base, contact system including set up movable contact spring on the base, set up on the base and with two static contacts of movable contact spring matched with, electromagnetic component including set up yoke on the base, set up coil skeleton on the yoke, set up coil on coil skeleton, set up the iron core in coil skeleton, rotate set up on the yoke and with iron core matched with armature, set up the shell fragment between armature and yoke, one of iron core serve and be provided with the magnetic ring with armature matched with, armature on the linkage be provided with and push away the frame, push away and be provided with two ejector pins of connection on the movable contact spring on the frame, and constitute movable contact spring and push away the linkage cooperation of frame.

The beneficial effect of above-mentioned structure is: the magnetic ring is arranged on the iron core and used for eliminating the electromagnetic force in the opposite direction when the alternating current passes through zero, so that the oscillation sound generated when the iron core runs is counteracted, the abrasion is reduced, and the purpose of driving the relay by alternating current can be realized. The armature pushes the movable reed through the pushing frame, so that reliable transmission between the armature and the pushing frame can be ensured. Therefore, the alternating current coil relay has the advantages of simple structure, stable and reliable performance, convenience in assembly and low cost.

Particularly, one end of the iron core is provided with a groove, two semicircular lugs are formed at two sides of the iron core corresponding to the groove, a semicircular hole matched with the semicircular lugs is formed in the magnetic ring, and the semicircular hole is clamped on one semicircular lug to form clamping matching of the iron core and the magnetic ring. The iron core and the magnetic ring are assembled in a clamping matching mode, so that the iron core and the magnetic ring are convenient to assemble, and the assembly efficiency of the electromagnetic relay is improved.

In particular, a partition is provided within the housing to separate the contact system from the electromagnetic assembly. The partition plate is separated between the contact system and the electromagnetic assembly, so that the creepage distance between the contact system and the electromagnetic assembly can be increased, and the working reliability of the electromagnetic relay is improved.
