Description

Technical Field

[0001] The invention relates to the field of magnetic latching relays, and in particular to a multi-group cross-phase symmetrical relay arrangement mechanism. Background Art

[0002] Magnetic latching relays are widely used in smart meters, reactive power compensation, intelligent control equipment and other fields. They are environmentally friendly relays. As long as the coil is energized, the relay contacts can be opened and closed. After completion, the coil does not need to be energized to maintain the state. The magnetic latching relay is maintained by the magnetism of the permanent magnet. The difference between magnetic latching relays and general relays is that they have a holding function. Once the pulse is triggered, the relay will maintain its original state even if the coil is powered off. Therefore, this type of relay has the effect of energy saving and electricity saving, which is in line with the development direction of the current social conservation society.

[0003] With the development of the electric meter industry and the further requirements for energy saving, the electric meter industry has gradually begun to require a higher degree of integration and high versatility for core parts such as relays to adapt to various metering solutions. The standardization of interface types is crucial to the design of metering solutions. Symmetrical relays can be compatible with various metering solution designs to the greatest extent, and can achieve compatibility with the diverse and standardized interface types.

[0004] The internal structure of the current magnetic latching relay is not compatible with the symmetrical type solution. When the current magnetic latching relay is used to make a symmetrical relay, due to the limitation of the internal load structure, a large amount of copper material needs to be used for grouping and isolation, resulting in a large waste of materials, and the coil structure cannot be avoided, resulting in poor short-circuit performance.

[0005] Currently, there is no public structural solution to the problem that, under the condition of limited volume, the reed cannot further reduce the structural deflection force, resulting in excessive product power.

[0006] The disclosure of the above background technology content is only used to assist in understanding the concept and technical solution of the present invention. It does not necessarily belong to the prior art of this patent application. In the absence of clear evidence that the above content has been disclosed on the filing date of this patent application, the above background technology should not be used to evaluate the novelty and creativity of the present application. Summary of the invention

[0007] The purpose of the present invention is to propose a multi-group cross-phase symmetrical relay arrangement mechanism to solve the technical problem that when the above-mentioned existing magnetic latching relays are used to make symmetrical relays, due to the limitation of the internal load structure, a large amount of copper material needs to be used for grouping and isolation, resulting in a large waste of materials, and the coil structure cannot be avoided, resulting in poor short-circuit performance.

[0008] In order to achieve the above technical objectives, the present invention adopts the following technical solutions:

[0009] A multi-group cross-phase symmetrical relay arrangement mechanism includes a mounting base, a mounting bracket, a connecting rod, a magnetic steel assembly, a coil assembly, a group 0 static spring assembly, a group 0 dynamic spring assembly, a group A cross-phase static spring assembly, a group A cross-phase dynamic spring assembly, a group B cross-phase static spring assembly, and a group B cross-phase dynamic spring assembly; the coil assembly, the magnetic steel assembly, the connecting rod, and the bracket are sequentially mounted on the mounting base in a positive direction to realize the electromagnetic switching action function; the group 0 static spring assembly, the group 0 dynamic spring assembly, the group A cross-phase static spring assembly, the group A cross-phase dynamic spring assembly, the group B cross-phase static spring assembly, and the group B cross-phase dynamic spring assembly directly cross the group 0 static spring assembly and the group 0 dynamic spring assembly, and the phases are isolated from each other using the mounting base.

[0010] Furthermore, the magnetic steel assembly is made of an armature piece, a permanent magnet and a plastic part by integral injection molding.

[0011] Furthermore, the coil assembly is made by winding the coil around a winding frame, installing an iron core and a yoke, and riveting and fastening them.

[0012] Furthermore, the 0 sets of static spring assemblies are made by riveting 0 sets of static spring seats, mounting static contacts and connecting pieces.

[0013] Furthermore, the 0 group of dynamic spring components are made of a first copper guide plate, a second copper guide plate, a third copper guide plate, and a first beryllium copper elastic plate, which are overlapped one by one and inserted into the dynamic contact and riveted and fastened, and then inserted into the 0 group of dynamic spring seats and riveted and fastened as a whole.

[0014] Furthermore, the A-group cross-phase static spring assembly is made by riveting the A-group cross-phase static spring seat with the static contact installed and the connecting piece.

[0015] Furthermore, the A group cross-phase dynamic spring assembly is made by overlapping the fourth copper guide plate, the fifth copper guide plate, the sixth copper guide plate, and the second beryllium copper elastic plate, which are inserted into the moving contact and riveted and fastened, and then inserted into the A group cross-phase dynamic spring seat and riveted and fastened as a whole.

[0016] Furthermore, the B group cross-phase static spring assembly is made by installing a static contact on the B group cross-phase static spring seat and riveting the connecting piece, and the B group cross-phase dynamic spring assembly is made by overlapping the seventh copper guide piece, the eighth copper guide piece, the ninth copper guide piece, and the third beryllium copper elastic piece one by one and inserting them into the moving contact and riveting them, and then inserting them into the B group cross-phase dynamic spring seat and riveting them as a whole.

[0018] Furthermore, the electromagnetic switching action function controls the on and off of three groups of electrical loads simultaneously through the connecting rod to realize the full function of the arrangement mechanism.

[0019] The present invention has the following beneficial effects:

[0020] 1. The multi-group cross-phase symmetrical relay arrangement mechanism of the present invention optimizes the technical limitations of existing magnetic latching relays when constructing a symmetrical layout. Specifically, it overcomes the defect that the traditional method has to rely on a large amount of copper materials to implement group isolation due to the constraints of the internal load structure. This practice not only leads to a large material loss, but also affects its short-circuit performance due to the difficulty in avoiding the coil structure.

[0021] 2. The present invention redesigns and plans the layout of the static spring components and the dynamic spring components of each phase of the relay, effectively solving the problem that the product space is small and cannot simultaneously meet the requirements of small product volume and stable phase isolation performance.

The present invention plans the product structure layout and increases the mutual interference distance between the product load circuit and the control current by 20% under the same volume, effectively solving the problem of reduced short-circuit resistance of the product due to mutual interference between the product load circuit and the control circuit.

It should be emphasized that the following description is merely exemplary and is not intended to limit the scope of the present invention and its application.

[0032] Non-limiting and non-exclusive embodiments will be described with reference to the following figures, wherein like reference numerals refer to like parts unless otherwise specifically stated.

[0033] Figure 1 It is a symmetrical solution without integrated design. Its disadvantage is that it needs three sets of input signals, has high requirements on power supply, does not have the advantage of energy saving, occupies a large volume, and has a complex design structure. Figure 2 For the integrated design structure, compare Figure 1 , only one set of input signals is required, which meets the energy-saving requirements, but there are 5 problems: the first is the large size; the second is the poor short-circuit performance; the third is that there is a short-circuit risk due to incomplete phase isolation, and the safety factor is low; the fourth is that the design structure is complex and not conducive to parts processing and manufacturing; the fifth is that the design structure is complex and not conducive to mass production and installation.

[0037] The magnetic steel assembly 4 is made of an armature plate, a permanent magnet and a plastic part which are integrally injected.

[0038] The coil assembly 5 is made by winding a coil around a bobbin, installing an iron core and a yoke, and then riveting and fastening them.

[0039] The 0-group static spring assembly 6 is made by riveting 0-group static spring seats with static contacts and connecting pieces.

[0040] The 0 group of dynamic spring components 7 are made of a first copper guide plate, a second copper guide plate, a third copper guide plate, and a first beryllium copper elastic plate, which are overlapped one by one and inserted into the dynamic contact and riveted and fastened, and then inserted into the 0 group of dynamic spring seats and riveted and fastened as a whole.

[0041] The A-group inter-phase static spring assembly 8 is made by riveting the A-group inter-phase static spring seat with the static contact installed and the connecting piece.

[0042] The A group cross-phase dynamic spring assembly 9 is made of a fourth copper guide plate, a fifth copper guide plate, a sixth copper guide plate, and a second beryllium copper elastic plate, which are overlapped one by one and inserted into the moving contact and riveted and fastened, and then inserted into the A group cross-phase dynamic spring seat and riveted and fastened as a whole.

[0043] The B group cross-phase static spring assembly 10 is made by installing a static contact and a connecting piece on a B group cross-phase static spring seat, and riveting together. The B group cross-phase dynamic spring assembly 11 is made by overlapping the seventh copper guide piece, the eighth copper guide piece, the ninth copper guide piece, and the third beryllium copper elastic piece one by one and inserting them into the dynamic contact and riveting them, and then inserting them into the B group cross-phase dynamic spring seat and riveting them as a whole.

Figure 3 In the arrangement structure, groups A and B bypass group 0.

[0045] Example 2

[0051] Through the multiple improved solutions of the present invention, compared with the existing technical solutions, the present invention shows significant technical advantages in multiple dimensions, which are specifically reflected in the following aspects:

[0052] 1. Innovative multi-group cross-phase symmetrical relay layout mechanism: This core design solves a major problem faced by traditional magnetic latching relays when making symmetrical relays. In the past, due to the limitations of the internal load structure, the manufacturing process had to rely on a large amount of copper to construct grouping partitions. This approach not only resulted in high material cost waste, but also made it difficult to effectively avoid the complex coil structure, which in turn affected the short-circuit performance of the relay and made it prone to failure in actual applications. The multi-group cross-phase symmetrical layout of the present invention avoids the above-mentioned defects through precise layout design, which not only reduces the use of copper materials, but also optimizes the coil structure layout, thereby significantly improving the short-circuit performance and overall stability of the relay.

[0053] 2. Optimized relay component layout: Faced with the problem of small product space and difficulty in taking into account both small size and stable phase-to-phase isolation performance, the present invention optimizes the layout of the static spring components and dynamic spring components of each phase of the relay through redesign. This change not only ensures efficient coordination between components, but also introduces the design of independent isolation slots between phases. This innovative design not only significantly enhances the reliability of the product and eliminates the potential risks caused by isolation failure from the source, but also further optimizes the internal structure of the product, so that it can show excellent performance even in a limited space.

[0054] 3. Full utilization of the vacant space at the front end: In order to solve the problem of limited space caused by product functional structure and volume limitation, the present invention cleverly utilizes the vacant space at the front end of the product that is usually not fully utilized, and maximizes the space utilization through compact and reasonable layout design. Combined with the structural characteristics of the new design, the present invention achieves a significant reduction in volume while ensuring that all necessary functions are fully retained. Compared with similar products, the volume of the present invention is reduced by at least 30%. This significant change not only facilitates the installation and deployment of the product, but also reduces logistics costs and improves market competitiveness.

[0055] 4. Optimization of product structure layout and improvement of mutual interference distance: In terms of product structure layout, the present invention also demonstrates good design thinking. By carefully planning the product structure, the present invention successfully increased the mutual interference distance between the product load circuit and the control current by 20% under the same volume. This improvement is crucial to improving the product's anti-short circuit function because it effectively solves the problem of product performance degradation caused by mutual interference between the load circuit and the control circuit. This design not only enhances the electrical isolation performance of the product, but also improves its stability and durability in complex electromagnetic environments, providing users with a more reliable and safe use experience.

[0056] In summary, the technical advantages of the present invention are not only reflected in technological innovation and performance improvement, but also bring significant economic and social benefits in practical applications, setting a new benchmark for the development of relay technology.

[0057] The above content is a further detailed description of the present invention in combination with specific preferred implementation modes. It cannot be determined that the specific implementation of the present invention is limited to these descriptions. For ordinary technicians in the relevant technical field, without departing from the concept of the present invention, they can also make several simple deductions or substitutions, which should be regarded as belonging to the scope of patent protection of the present invention determined by the submitted claims.
