Description

Technical Field

[0001] This utility model relates to the field of ferrite core technology, and in particular to a ferrite core assembly for relays. Background Technology

[0002] Ferrite cores are ceramic materials made by sintering iron oxides with other metal oxides (such as magnesium, manganese, and zinc). They possess excellent magnetic permeability and low loss characteristics. They are typically machined into toroidal, rod-shaped, or other geometric shapes to manage the transmission and conversion of electromagnetic energy.

[0003] Relays are typically equipped with corresponding ferrite cores, which contain many internal components that need to be reassembled, making assembly quite troublesome. In addition, the ferrite core is connected to the relay housing through multiple sets of pins, which are usually made of copper wire, which is relatively soft and has poor impact resistance. Utility Model Content

[0004] In view of the shortcomings of the prior art, this utility model provides a ferrite core assembly for relays, which overcomes the shortcomings of the prior art and effectively solves the problems of complicated assembly and poor impact resistance.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A ferrite core assembly for a relay includes a core component and a frame component externally disposed thereon. The core component includes an upper ferrite core and a lower ferrite core, and the upper and lower ferrite cores are of the same size. The frame component includes an upper sandwich plate, a sleeve, and a base. The upper and lower ferrite cores are slidably connected to the inner wall of the sleeve. Angle plates are disposed around the outer wall of the base, and internal threaded washers are disposed on the inner wall of the angle plates.

[0007] Preferably, rectangular blocks are provided on both outer walls of the base at equal intervals, and pins are inserted into the bottom outer wall of the rectangular blocks.

[0008] Preferably, a coil is wound on the outer wall of the sleeve, and an annular insulating layer is wrapped on the outer wall of the coil.

[0009] Preferably, a resin connecting block is fixedly connected between the annular insulating layer and the iron core.

[0010] Preferably, a rectangular insulating layer is bonded to the outer wall of the upper ferrite core and the lower ferrite core.

[0011] Preferably, the base has a relay housing at its bottom, and a fastening screw is fixedly connected between the internal threaded washer and the relay housing.

[0012] The beneficial effects of this utility model are as follows:

[0013] 1. The ferrite core assembly for relays designed in this paper adopts an integral molding structure for the skeleton component. The upper sandwich plate, sleeve and base are combined together, which allows the upper ferrite core and lower ferrite core to be quickly assembled onto the skeleton component, reducing the assembly difficulty and improving the installation efficiency.

[0014] 2. The ferrite core assembly for relays designed in this paper adds multiple fasteners to the skeleton component. The fasteners include corner plates and internal threaded washers. The internal threaded washers can fit tightly against the relay bottom shell. Under the tightening action of the fastening screws, the overall stability of the ferrite core assembly can be increased, and the impact resistance of the ferrite core assembly can be improved.
