Description

Technical Field

[0001] The present invention relates to the technical field of relays, and in particular to a seesaw type armature mounting structure, a relay magnetic circuit structure and a relay. Background Art

[0002] Electromagnetic relays generally include a base, a housing, a magnetic circuit, and an armature. If the armature is designed as a seesaw type, a shaft needs to be fixed in the middle of the armature to achieve functional rotation of the armature. An existing armature shaft fixing structure is to add an injection-molded shaft bracket to the coil frame, and the shaft on the armature is rotatably mounted on the shaft bracket. However, since the shaft bracket is a plastic structure, the coil part will generate high temperature during the operation of the relay, and the plastic shaft bracket may deform and other defects under abnormally high temperature conditions, which will cause the armature part to rotate inflexibly and unstable, resulting in the relay being unable to work normally and stably. Summary of the invention

[0003] In view of the deficiencies of the prior art, the present invention provides a seesaw armature mounting structure, which mainly solves the technical problem that the existing rotating shaft bracket injection-molded on the coil frame is easily deformed by the high temperature generated by the coil part.

[0004] To achieve the above object, the present invention is achieved through the following technical solutions: A seesaw type armature mounting structure comprises an armature component and two non-magnetic side shaft frames, the armature component is provided with a rotating shaft, and both side shaft frames are provided with rotating shaft mounting positions adapted to the rotating shaft, and the two side shaft frames are configured to be fixedly connected between two yokes of a relay magnetic circuit structure, and the armature component is rotationally connected to the two side shaft frames by respectively rotating the two ends of the rotating shaft with the rotating shaft mounting positions on the two side shaft frames.

[0005] Furthermore, the armature component includes an armature body and a rotating seat fixedly connected to the bottom of the armature body, and the rotating shaft is connected to the rotating seat.

[0006] Furthermore, a shaft hole is provided on the rotating seat, and the rotating shaft is inserted into the shaft hole with interference fit and is thus fixedly connected to the rotating seat;

[0007] Furthermore, the rotating seat is made of plastic material, and the rotating seat is fixedly connected to the armature body by riveting.

[0008] Furthermore, the side shaft frame is configured to be fixedly connected between the sides of the two yokes of the relay magnetic circuit structure; the mounting position on the side shaft frame is a mounting hole structure or a mounting groove structure adapted to the end of the rotating shaft.

[0009] Furthermore, the side shaft frame is a non-magnetic copper shaft frame structure;

[0010] Furthermore, the two ends of the side shaft frame are respectively welded and fixed to the sides of the two yokes of the relay magnetic circuit structure.

[0011] Furthermore, positioning grooves are provided at the sides of the two yokes of the relay magnetic circuit structure, and the two ends of the side shaft frame are respectively embedded in the positioning grooves of the corresponding side yokes;

[0012] Furthermore, after the side shaft frame and the two yokes are assembled, the side edges of the side shaft frame and the side edges of the two yokes are flush.

[0013] Based on the same inventive concept, the present invention also provides a relay magnetic circuit structure, including any of the above-mentioned seesaw armature mounting structures and a coil frame, an iron core installed in the through hole of the coil frame, a coil wound on the coil frame and two yokes respectively fixedly connected to the two ends of the iron core, two side shaft frames fixedly connected between the two yokes, and the two ends of the rotating shaft on the armature component are respectively rotatably connected to the two side shaft frames.

[0014] Furthermore, the two yokes are fixed to the two ends of the iron core by riveting.

[0015] Based on the same inventive concept, the present invention also provides a relay, comprising any of the relay magnetic circuit structures described above.

[0016] Based on the same inventive concept, the present invention also provides an assembly method of a relay magnetic circuit structure, comprising the following steps: S1, install the iron core into the through hole of the coil frame, wind the coil on the coil frame, and then fix the two yokes to the two ends of the iron core respectively, and fix the armature body and the rotating seat together in advance, and assemble the rotating shaft to the rotating seat accordingly; S2, first fix the end of one of the two side shaft frames to the same side of the two yokes; then insert one end of the rotating shaft on the rotating seat into the shaft hole of the side shaft frame; S3, then install the other side shaft frame, assemble the shaft hole of the other side shaft frame with the other end of the rotating shaft correspondingly, and then fix the two ends of the other side shaft frame to the other side of the two yokes respectively.

[0017] The above technical solution has the following advantages or beneficial effects:

[0018] In the seesaw armature mounting structure, relay magnetic circuit structure and relay described in the present invention, two side shaft frames are cleverly arranged between the two original yokes in the relay magnetic circuit structure, and the remaining space between the two yokes is fully utilized to arrange a structure for supporting the rotation of the armature component, which is conducive to the miniaturization of the relay. In addition, the side shaft frames do not directly contact the coil part in the relay magnetic circuit structure, and are not affected by the high temperature generated when the coil is working and produce defects such as deformation, which greatly ensures the rotation stability of the armature component. Moreover, its assembly is simple and convenient, which is conducive to automatic assembly to improve assembly efficiency. BRIEF DESCRIPTION OF THE DRAWINGS

[0026] Please refer to the attached Figure 1 To Attachment Figure 3One embodiment of the present invention provides a seesaw armature mounting structure, including an armature component 1 and two non-magnetic side shaft frames 2, the armature component 1 is provided with a rotating shaft 3, and both side shaft frames 2 are provided with a rotating shaft mounting position 21 adapted to the rotating shaft 3, and the side shaft frames 2 are configured to be fixedly connected between two yokes 4 of the relay magnetic circuit structure, and the armature component 1 is rotatably connected with the side shaft frames 2 by the two ends of the rotating shaft 3 respectively rotating with the rotating shaft mounting positions 21 on the side shaft frames 2. It can be understood that in this embodiment, the side shaft frames 2 are cleverly arranged between the two yokes 4 originally in the relay magnetic circuit structure, and the remaining space between the two yokes 4 is fully utilized to arrange a structure for supporting the rotation of the armature component 1, which is conducive to the miniaturization of the relay, and the side shaft frames 2 do not directly contact the coil part in the relay magnetic circuit structure, and are not affected by the high temperature generated when the coil is working and produce defects such as deformation, which greatly ensures the rotation stability of the armature component 1, and its assembly is simple and convenient, which is conducive to automatic assembly to improve assembly efficiency. In addition, compared to the prior art, the armature component 1 is installed by adding two side shaft frames 2.
