Description

Technical Field

[0001] This utility model relates to the field of relay technology, and in particular to a relay. Background Technology

[0002] A relay is an electrical control device that uses electromagnetic force to control the switching of a circuit. Existing relays typically consist of a coil, iron core, contacts, and a housing, and may include dual-channel relays. In a dual-channel relay, a push plate synchronously drives two sets of contacts to actuate, thereby achieving closure or opening.

[0003] However, in actual assembly, it was found that because the existing pushers are manufactured as a single piece, these structures need to be precisely aligned with the corresponding positions on the product to be successfully installed. Otherwise, the position of the entire pusher needs to be readjusted or it needs to be reassembled from scratch, which makes the assembly process more complicated and difficult, and there is room for improvement.

Detailed Implementation

[0025] To better understand and implement this invention, the technical solutions in the embodiments of this invention will be clearly and completely described below with reference to the accompanying drawings.

[0026] In the description of this utility model, it should be noted that the terms "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", and "outer" indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0027] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains. The terminology used herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention.

[0028] The present invention discloses a relay, which is described below in conjunction with the accompanying drawings. Figures 1-4 The technical solution of this relay is described in detail.

[0029] Specifically, the relay includes a housing 1 and a contact portion assembled within the housing 1. The contact portion includes a first contact assembly, a second contact assembly, and a connecting assembly. The first contact assembly includes a first stationary spring 2 and a first movable spring 3. The second contact assembly includes a second stationary spring 4 and a second movable spring 5. The connecting assembly includes a first push plate 6 and a second push plate 7. One end of the first push plate 6 is connected to the first movable spring 3, one end of the second push plate 7 is connected to the second movable spring 5, and the other ends of the first push plate 6 and the second push plate 7 are engaged.

[0030] This relay does not employ the existing one-piece push-plate structure, but rather a two-section push-plate structure: a first push-plate 6 and a second push-plate 7 that interlock with each other. This design offers greater flexibility during assembly. Because of the limitations of the one-piece structure, the one-piece push-plate requires precise alignment with the complex internal structure when installed in a specific position on the relay, making the operation difficult. The two-section structure allows the first push-plate 6 to be placed in the appropriate position first, and then the second push-plate 7 to be connected to it via a snap-fit ​​mechanism. For example, in situations where the internal space of the relay is narrow and there are other components obstructing the way, the separately installed push-plates can more easily bypass these obstacles and be accurately installed. Assembling them one by one is easier than installing a single, integrated structure, simplifying the overall assembly process, shortening assembly time, and improving overall work efficiency.

[0031] In addition, this relay improves assembly precision, thereby enhancing product performance consistency. The two-section pusher structure allows for step-by-step adjustments during assembly. For example, when installing the first pusher 6, its position and angle can be initially adjusted to ensure a good fit with internal relay components (such as the first contact assembly). Then, when installing the second pusher 7, the overall position and angle can be further fine-tuned through a snap-fit ​​mechanism, improving installation precision. In contrast, with a one-piece pusher, positional deviations during initial installation are difficult to adjust locally, potentially affecting relay operation. For instance, in situations requiring precise alignment between the pusher and relay contacts, the two-section pusher allows for better adjustment through the mutual adjustment of the two components, ensuring accurate contact and guaranteeing relay electrical performance.

[0032] In summary, this relay adopts a two-stage push-plate structure to simplify the overall assembly process and facilitate assembly; at the same time, it can shorten the assembly time, improve the overall work efficiency, and improve the consistency of product performance within a limited space.

[0033] To better understand the assembly of this relay, a simplified assembly process will be used as an example:

[0034] During assembly, the first push plate 6 and the first moving spring 3 can be assembled together first, and then assembled together with the first stationary spring 2 into the housing 1; next, the second push plate 7 and the second moving spring 5 can be assembled together and then assembled into the housing 1, and the second push plate 7 and the first push plate 6 can be engaged; finally, the second stationary spring 4 can be assembled into the housing 1 to complete the assembly of the contact parts.

[0035] Specifically, regarding the arrangement of the contact parts, in actual products, they can be arranged at intervals in the same direction, that is, the first moving spring 3, the first stationary spring 2, the first push plate 6, the second push plate 7, the second moving spring 5, and the second stationary spring 4 are arranged at intervals in the same direction. In the illustrated embodiment, the first moving spring 3, the first stationary spring 2, the first push plate 6, the second push plate 7, the second moving spring 5, and the second stationary spring 4 can be specifically arranged at intervals in the transverse direction, i.e., the X direction in the illustration. Therefore, this relay is particularly suitable for relays with transversely arranged contact parts.

[0036] Of course, in other embodiments, other arrangements can also be adopted. For example, the first stationary spring 2, the first moving spring 3, the first pusher 6, the second pusher 7, the second moving spring 5, and the second stationary spring 4 are arranged at intervals in the same direction; or, the first moving spring 3, the first stationary spring 2, the first pusher 6, the second pusher 7, the second stationary spring 4, and the second moving spring 5 are arranged at intervals in the same direction; or, the first stationary spring 2, the first moving spring 3, the first pusher 6, the second pusher 7, the second stationary spring 4, and the second moving spring 5 are arranged at intervals in the same direction.

[0037] Specifically, the first moving spring 3 includes a first moving spring body 31 and a first moving spring contact part 32, and one end of the first push plate 6 passes through the first stationary spring 2 and is connected to the first moving spring contact part 32.

[0038] In the illustrated embodiment, the first moving spring body 31, the first moving spring contact 32, the first stationary spring 2, the first pusher 6, the second pusher 7, the second moving spring 5, and the second stationary spring 4 are arranged laterally at intervals. Furthermore, since the first pusher 6 needs to connect with the first moving spring contact 32, to avoid interference between the first pusher 6 and the first stationary spring 2 and to make the structure more compact, the first pusher 6 and the first stationary spring 2 are connected by a through-hole arrangement. Specifically, the first pusher 6 and the first stationary spring 2 are passed through before connecting to the first moving spring contact 32 of the first moving spring 3, which can be described as a hook connection.

[0039] This configuration allows for efficient assembly. During assembly, the first stationary spring 2 can be inserted into the first pusher 6 and then connected to the first moving spring 3, forming a single unit. This allows for rapid positioning and connection of components, reducing assembly time and steps, thereby improving overall production efficiency and lowering production costs. Furthermore, it establishes a stable connection between the first pusher 6, the first stationary spring 2, and the first moving spring 3. This structure effectively resists external impacts and vibrations, ensuring that components are not prone to displacement or loosening during equipment operation, thus guaranteeing reliable operation and extending the equipment's service life.

[0040] Specifically, the second moving spring 5 includes a second moving spring body 51 and a second moving spring contact part 52, and one end of the second pusher 7 passes through the second moving spring body 51 and is connected to the second moving spring contact part 52.

[0041] Similarly, in the illustrated embodiment, the first moving spring body 31, the first moving spring contact 32, the first stationary spring 2, the first pusher 6, the second pusher 7, the second moving spring body 51, the second moving spring contact 52, and the second stationary spring 4 are arranged at transverse intervals. Furthermore, since the second pusher 7 needs to connect with the second moving spring contact 52, to avoid interference between the second pusher 7 and the second moving spring body 51 and to make the structure more compact, the second pusher 7 and the second moving spring body 51 are connected by a through-hole arrangement. Specifically, the second pusher 7 passes through the second moving spring body 51 before connecting with the second moving spring contact 52, which can be described as a hook connection.

[0042] With this configuration, during actual assembly, the first stationary spring 2 can be inserted into the first push plate 6 and then connected with the first moving spring 3 to form a whole, which can then be assembled into the housing 1. Next, the second moving spring body 51 of the second moving spring 5 can be inserted into the second push plate 7 and then connected with the second moving spring contact 52 of the second moving spring 5 to form a whole, which can then be assembled into the housing 1. Finally, the second stationary spring 4 can be assembled into the housing 1.

[0043] This allows for rapid positioning and connection of various components, reducing assembly time and procedures, thereby improving overall production efficiency and lowering production costs. Furthermore, it establishes a stable connection between the second push plate 7 and the second stationary spring plate 4. This structure effectively resists external impacts and vibrations, ensuring that components are not prone to displacement or loosening during equipment operation, thus guaranteeing reliable equipment operation and extending its service life.

[0044] Specifically, the other end of the first pusher 6 has a first engaging portion 61, and the other end of the second pusher 7 has a second engaging portion 71; the first engaging portion 61 and the second engaging portion 71 form a ring-shaped engaging structure. In the illustrated embodiment, a ring-shaped engaging structure can be used for the specific engaging structure. The purpose of this design is that the ring-shaped structure can apply constraint forces to the engaged components from multiple directions, thereby ensuring that the position of the connected components is relatively fixed, thus enhancing connection stability. Furthermore, from an installation perspective, during the installation process, the ring-shaped engaging structure can be installed simply by aligning the engaged components with the opening of the engaging structure and pushing them in with appropriate force, facilitating installation and disassembly.

[0045] For a specific snap-fit ​​structure, please refer to the embodiment shown in the figure. Specifically, the first snap-fit ​​portion 61 includes a first snap-fit ​​segment 611, a second snap-fit ​​segment 612, and a third snap-fit ​​segment 613 connected at their ends in sequence. The length of the third snap-fit ​​segment 613 is shorter than the length of the first snap-fit ​​segment 611, forming an L-shaped first snap-fit ​​interface 62. This arrangement makes the overall snap-fit ​​structure more compact, allowing for more efficient use of space in the internal layout of the device or product, avoiding spatial conflicts with other components, and contributing to the miniaturization of the device.

[0046] Specifically, the second latching portion 71 includes a fourth latching segment 711, a fifth latching segment 712, and a sixth latching segment 713 connected at their ends in sequence. The length of the sixth latching segment 713 is shorter than the length of the fourth latching segment 711, forming an L-shaped second latching interface 72. This arrangement allows for a more compact overall latching structure, enabling more efficient use of space within the internal layout of the device or product, avoiding spatial conflicts with other components, and contributing to the miniaturization of the device. Furthermore, in actual assembly, the first latching portion 61 is fitted into the first latching interface 62, and the second latching portion 71 is fitted into the second latching interface 72, forming a mutually restraining latching structure that further improves the connection stability of the structure.

[0047] In other embodiments, the circumferential snap-fit ​​structure can also be, for example, a snap ring structure, specifically two snap rings, one with a larger diameter and the other with a smaller diameter, the smaller diameter snap ring snapping into the larger diameter snap ring. Furthermore, an interference-avoidance notch can be provided at the larger diameter snap ring to facilitate the snapping into the smaller diameter snap ring.

[0048] Specifically, the first card interface 62 extends out along one side of the width of the first push piece 6. This design facilitates the insertion and positioning of the second card connector 71, resulting in more precise card insertion and reducing errors during the insertion process. Furthermore, since the first card interface 62 only extends out on one side, the other side is effectively closed, thus acting as a limit when the second card connector 71 is inserted, preventing it from dislodging.

[0049] Specifically, the second card interface 72 extends through both sides along the width direction of the second push piece 7. This design facilitates the insertion and positioning of the first card connector 61, thereby enabling more precise card insertion and reducing errors during the insertion process.

[0050] Specifically, one of the first push plate 6 and the second push plate 7 is provided with an abutment portion 8 for movably connecting with the actuating rod of the magnetic circuit section. In the illustrated embodiment, the abutment portion 8 can be specifically an abutment groove for being pushed by the actuating rod of the magnetic circuit section. When the magnetic circuit section is working, it drives the actuating rod to move. Since the abutment portion 8 of the first push plate 6 is movably connected to the actuating rod, the movement of the actuating rod will drive the first push plate 6 to move synchronously, thereby realizing the connection or disconnection between the first moving spring 3 and the first stationary spring 2, and the connection or disconnection between the second moving spring 5 and the second stationary spring 4.

[0051] Specifically, the axis along which the first push plate 6 and the second push plate 7 are driven as a whole is parallel to the axis along which the first push plate 6 and the second push plate 7 are arranged at intervals. This arrangement facilitates a more compact design because the driving direction and the interval arrangement direction are consistent. When designing the shape and internal structure of the device, space can be better utilized without reserving excessive extra space to accommodate complex force directions, thus enabling a more efficient functional layout within a limited space.

It should be noted that those skilled in the art can make various improvements and modifications without departing from the principle of this utility model, and these improvements and modifications are also considered within the scope of protection of this utility model.
