Description

Technical Field

[0001] The utility model relates to the technical field of relays, and particularly relates to an alnico permanent magnet for a relay. Background Technique

[0002] A relay is an electrical control device that can establish an interaction relationship between a control system (input loop) and a controlled system (output loop). When the input quantity (such as current, voltage, temperature, etc.) reaches a certain threshold value, the relay will make the controlled output circuit conduct or disconnect. The working principle of the relay is usually based on electromagnetic induction, in which the coil is energized to generate a magnetic field, attracting the iron core, and then driving the contact to close or open to achieve circuit switching. Alnico permanent magnet is an important permanent magnet material with high permanent magnetic performance and good stability, and is widely used in the fields of electric power, instrumentation, electronic industry, medical equipment, radar communication, etc. In a relay, as a key component, the alnico permanent magnet not only needs to meet the magnetic characteristics to ensure the reliability and accuracy of the relay action, but also needs to meet the mechanical performance requirements as a structural component to ensure the quality reliability and service life of the product.

[0003] At present, during the installation and use of the existing alnico permanent magnet inside the relay, the alnico permanent magnet belongs to a hard and brittle material, and its mechanical properties are not as good as those of some other permanent magnet materials, such as rare earth permanent magnet materials. This may lead to situations such as easy breakage of the alnico permanent magnet during use, affecting the service life of the alnico permanent magnet. To solve this technical problem, the utility model proposes an alnico permanent magnet for a relay. Content of the Utility Model

[0005] To achieve the above purpose, the technical solution adopted by the utility model is as follows:

[0006] An alnico permanent magnet for a relay includes a storage cylinder, a magnet body, and a combined plate. A first rubber ring is arranged on the outer side of the storage cylinder, an inner cylinder is arranged inside the storage cylinder, the combined plate is arranged at the top of the storage cylinder, a second rubber ring is arranged on the outer side of the combined plate, and both the first rubber ring and the second rubber ring are made of flexible rubber material.

[0007] Preferably, a plurality of groups of first through grooves are penetrated and opened inside the storage cylinder, and a plurality of groups of second through grooves are correspondingly penetrated and opened inside the combined plate and the storage cylinder.

[0013] In the utility model, by arranging components such as a first rubber ring and a second rubber ring, after the combined plate is combined and arranged at the top end of the storage cylinder, the combined plate can limit the position so that the magnet steel body is arranged inside the storage cylinder. After the combined plate is connected to the storage cylinder, the first rubber ring and the second rubber ring can be used to flexibly protect the outer sides of the storage cylinder and the combined plate, avoiding the occurrence of damage and other situations caused by collision of the alnico magnet during use, and effectively improving the service life of the alnico magnet.

[0014] In the utility model, by arranging components such as insertion plates and movable frames, after the combined plate is inserted into the first through groove formed inside the storage cylinder, at this time, the insertion plates arranged at the bottom end of the combined plate are located on one side of the mounting plate arranged inside the first through groove. The movable frame is movably connected between two guide rods. The guide rods can linearly limit the movement of the movable frame. By connecting one end of the spring arranged on the outer side of the guide rod to the movable frame, the spring can elastically push the movable frame to movably penetrate through the mounting plate, and the movable frame can be inserted into the positioning holes formed inside the insertion plates, positioning the insertion plates inside the first through groove.
