Description

Technical Field

[0001] The utility model relates to the field of magnetic latching relays, in particular to a relay arrangement mechanism for optimizing cross-phase short-circuit performance. Background Art

[0002] Magnetic latching relays are widely used in smart meters, reactive power compensation, intelligent control equipment, and other fields. These environmentally friendly relays ensure the opening and closing of the relay contacts as soon as the coil is momentarily energized. After this, the contacts remain in this state without further energizing the coil. This state is maintained by the magnetic properties of a permanent magnet. Unlike conventional relays, magnetic latching relays have a latching function: once triggered by a pulse, the relay maintains its original state even when the coil is de-energized. Therefore, this type of relay is energy-efficient and in line with the current trend toward a more energy-efficient society.

[0003] With the development of the electric meter industry and the further requirements for energy conservation, the electric meter industry has gradually begun to require a higher degree of integration and high versatility for the core component relay to adapt to various meter solutions. Among them, the standardization of interface types is crucial to the design of meter solutions. Symmetrical relays can be compatible with various meter solution designs to the greatest extent and achieve compatibility with 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 limitations 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 material, 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 conditions 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 utility model. 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 this application.

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

[0009] A relay arrangement mechanism for optimizing cross-phase short-circuit performance 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 in a forward direction on the mounting base to realize an electromagnetic switching 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.

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

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

[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 static spring assembly 6 is made of a static spring seat, a static contact, and a connecting piece riveted together.

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

[0052] 1. Innovative cross-phase short-circuit performance optimization 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 group partitions. This approach not only resulted in high material cost waste, but also made it difficult to effectively avoid complex coil structures, 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 utility model 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 improving the short-circuit performance and overall stability of the relay.

[0053] 2. Optimized Relay Component Layout: Faced with the challenge of achieving both compact size and stable phase-to-phase isolation performance in a limited product space, this utility model has redesigned and optimized the layout of the static and dynamic spring assemblies for each phase of the relay. This change not only ensures efficient coordination between components but also introduces independent isolation slots between phases. This innovative design not only enhances product reliability, eliminating potential risks associated with isolation failure, but also further optimizes the product's internal structure, enabling superior performance even within limited space.

[0054] 3. Full Utilization of Front-End Vacant Space: Addressing the issue of limited space due to product functionality and volume constraints, this new design cleverly utilizes the typically underutilized space at the front of the product. This maximizes space utilization through a compact and rational layout. Combined with the structural features of this new design, this new design significantly reduces volume while preserving all necessary functions. Compared to similar products, this new design's volume is reduced by at least 30%. This change not only facilitates product installation and deployment, but also reduces logistics costs and enhances market competitiveness.

[0055] 4. Optimization of product structure layout and improvement of mutual interference distance: In terms of product structure layout, the utility model also demonstrates good design thinking. Through careful planning of the product structure, the utility model 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 short-circuit resistance 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 product's electrical isolation performance, but also improves its stability and durability in complex electromagnetic environments, providing users with a more reliable and safe user experience.

[0056] In summary, these technical advantages of the present invention are not only reflected in technological innovation and performance improvement, but also bring good economic and social benefits in practical applications.

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 falling within the scope of patent protection of the present invention as determined by the submitted claims.
