Description

Technical Field

[0001] This utility model relates to the field of relay technology, specifically to a rocker armature mounting structure, a relay magnetic circuit structure, and a relay. Background Technology

[0002] Electromagnetic relays generally consist of a base, a housing, a magnetic circuit, and an armature. If the armature is designed as a rocker type, a pivot is needed in the middle of the armature to fix it, thus enabling the armature to rotate. One existing structure for fixing the armature pivot involves adding an injection-molded pivot bracket to the coil frame. The pivot on the armature is rotatably mounted on this bracket. However, because the pivot bracket is made of plastic, the coil generates high temperatures during relay operation. Under abnormally high temperatures, the plastic pivot bracket may deform, leading to inflexible and unstable rotation of the armature, causing the relay to malfunction and fail to operate stably. Utility Model Content

[0003] To address the shortcomings of existing technologies, this utility model provides a rocker armature mounting structure, which mainly solves the technical problem that the existing injection-molded shaft support on the coil frame is prone to deformation due to the high temperature generated by the coil.

[0004] To achieve the above objectives, this utility model is implemented through the following technical solution:

[0005] A rocker armature mounting structure includes an armature component and two non-magnetic side shaft brackets. The armature component is provided with a rotating shaft, and each of the two side shaft brackets is provided with a rotating shaft mounting position adapted to the rotating shaft. The two side shaft brackets are configured to be fixedly connected between the two yokes of the relay magnetic circuit structure. The armature component is rotatably connected to the two side shaft brackets by the rotational engagement of the two ends of the rotating shaft with the rotating shaft mounting positions on the two side shaft brackets.

[0006] Furthermore, the armature component includes an armature body and a rotating seat fixedly connected to the bottom of the armature body, with the rotating shaft connected to the rotating seat.

[0007] Furthermore, the rotating seat is provided with a shaft hole, and the rotating shaft is interference-fitted into the shaft hole and thus fixedly connected to the rotating seat;

[0008] Furthermore, the rotating base is made of plastic and is fixedly connected to the armature body by hot riveting.

[0009] Furthermore, the side shaft bracket 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 bracket is a mounting hole structure or a mounting groove structure adapted to the end of the rotating shaft.

[0010] Furthermore, the side bearing is a non-magnetic copper bearing structure;

[0011] Furthermore, the two ends of the side shaft bracket are welded and fixed together with the sides of the two yokes of the relay magnetic circuit structure.

[0012] Furthermore, positioning grooves are provided on the sides of both yokes of the relay magnetic circuit structure, and the two ends of the side shaft bracket are respectively embedded in the positioning grooves of the corresponding side yokes.

[0013] Furthermore, after the side axle bracket and the two yokes are assembled, the side of the side axle bracket is flush with the side of the two yokes.

[0014] Based on the same inventive concept, this utility model also provides a relay magnetic circuit structure, including any of the above-described rocker armature mounting structures, 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 both ends of the iron core. The two side shaft frames are fixedly connected between the two yokes, and the two ends of the rotating shaft on the armature component are rotatably connected to the two side shaft frames respectively.

[0015] Furthermore, the two yokes are riveted and fixed to both ends of the iron core.

[0016] Based on the same inventive concept, this utility model also provides a relay, including any of the relay magnetic circuit structures described above.

[0017] Based on the same inventive concept, this utility model also provides a method for assembling a relay magnetic circuit structure, comprising the following steps:

[0018] S1, install the iron core into the through hole of the coil frame, wind the coil on the coil frame, 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 onto the rotating seat accordingly;

[0019] S2, first fix the end of one side shaft bracket of the two side shaft brackets 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 bracket.

[0020] S3. Next, install the other side shaft bracket, assemble the shaft hole of the other side shaft bracket with the other end of the rotating shaft, and then fix the two ends of the other side shaft bracket to the other side of the two yokes respectively.

[0021] The above technical solution has the following advantages or beneficial effects:

[0022] The rocker armature mounting structure, relay magnetic circuit structure, and relay described in this utility model cleverly incorporate side shaft brackets between the original two yokes in the relay magnetic circuit structure. This fully utilizes the remaining space between the two yokes to create a structure that supports the rotation of the armature component, which is beneficial for relay miniaturization. Furthermore, the side shaft brackets do not directly contact the coil portion in the relay magnetic circuit structure, thus avoiding deformation and other defects caused by the high temperature generated during coil operation. This greatly ensures the rotational stability of the armature component, and its assembly is simple and convenient, facilitating automated assembly to improve assembly efficiency.

[0030] Please refer to the appendix. Figure 1 To be continued Figure 3One embodiment of this utility model provides a rocker armature mounting structure, including an armature component 1 and two non-magnetic side shaft brackets 2. The armature component 1 is provided with a rotating shaft 3, and each of the two side shaft brackets 2 has a rotating shaft mounting position 21 adapted to the rotating shaft 3. The two side shaft brackets 2 are configured to be fixedly connected between the two yokes 4 of the relay magnetic circuit structure. The armature component 1 is rotatably connected to the two side shaft brackets 2 by the rotational engagement of the two ends of the rotating shaft 3 with the rotating shaft mounting positions 21 on the two side shaft brackets 2. It can be understood that in this embodiment, the two side shaft brackets 2 are cleverly set between the original two yokes 4 in the relay magnetic circuit structure, making full use of the remaining space between the two yokes 4 to set up a structure for supporting the rotation of the armature component 1, which is conducive to the miniaturization of the relay. In addition, the side shaft brackets 2 do not directly contact the coil part in the relay magnetic circuit structure, and are not affected by the high temperature generated during the operation of the coil, thus avoiding defects such as deformation. This greatly ensures the rotational stability of the armature component 1, and its assembly is simple and convenient, which is conducive to realizing automatic assembly and improving assembly efficiency. Furthermore, compared to existing technologies, by adding two side shaft brackets 2 to install the armature component 1, since the two side shaft brackets 2 are directly fixed to the two yokes 4, there is no need to connect other components such as the relay base or frame, and they are not affected by other components. This makes the installation position of the side shaft brackets 2 more accurate and stable, which is conducive to further improving the rotational stability of the armature component 1.

Preferably, the side shaft bracket 2 is a non-magnetic copper shaft bracket structure; however, those skilled in the art should understand that in other embodiments, the side shaft bracket 2 can also be made of other non-magnetic materials, and is not limited to the specific implementation disclosed in this embodiment. Copper is preferred for making the side shaft bracket 2, on the one hand, considering that metal materials have better support stability, and on the other hand, copper can also be better welded and fixed to the two yokes 4, making the installation and fixing of the side shaft bracket 2 convenient, quick and stable, which is beneficial to improving the rotational stability of the armature body 11.

[0034] Please refer to the appendix. Figure 1 To be continued Figure 3 In one preferred embodiment, the two ends of the side shaft bracket 2 are welded and fixed to the sides of the two yokes 4 of the relay magnetic circuit structure. Preferably, positioning grooves 41 are provided on the sides of the two yokes 4 of the relay magnetic circuit structure, and the two ends of the side shaft bracket 2 are respectively embedded in the positioning grooves 41 of the corresponding side yokes 4; in this way, the assembly positioning accuracy between the side shaft bracket 2 and the two yokes 4 can be effectively improved, and the skewness of the rotating shaft 3 assembly can be avoided, which would affect the rotational flexibility of the armature body 11.
