Description

Technical Field

[0001] This application relates to the field of relay technology, and in particular to relays. Background Technology

[0002] A relay is an electrical control device that causes a predetermined step change in the controlled variable in the electrical output circuit when the change in the input quantity (excitation quantity) reaches a specified requirement. It has an interactive relationship between the control system (also known as the input circuit) and the controlled system (also known as the output circuit). Commonly used in automated control circuits, it is essentially an "automatic switch" that uses a small current to control a large current, thus playing roles in automatic adjustment, safety protection, and circuit switching.

[0003] A relay typically consists of a contact portion that serves as the high-voltage end and a magnetic circuit portion that serves as the low-voltage end. The contact portion and the magnetic circuit portion are connected and operated by a pusher (usually an iron part), and they are usually insulated from each other by a single injection molding process. However, the existing single injection molding method is not only costly but also has a long processing cycle. Utility Model Content

[0022] In one embodiment, the second plug-in portion is provided with a plug-in extension portion, at least a portion of the structure of the plug-in extension portion is located between the second plate and the magnetic circuit actuating member, for limiting the relative position of the second plate and the magnetic circuit actuating member in the height direction; wherein, the plug-in extension portion and the second plug-in portion are configured as an integrally formed structure or a separate structure.

[0023] In one embodiment, the magnetic circuit actuator includes a magnetic guide plate, the first insertion portion is disposed on the magnetic guide plate, and the distance between the second plate and the magnetic guide plate is adapted to the height of the insertion extension portion, thereby clamping the insertion extension portion between the second plate and the magnetic guide plate, and making the contact portion relatively limited to the magnetic circuit actuator in the direction of movement.

[0024] In one embodiment, the second insertion hole is configured as an irregular hole, the second insertion part is configured as an irregular post, and the second insertion hole and the second insertion part are inserted into each other to restrict the relative rotation between the second insertion hole and the second insertion part.

The transmission component realizes the connection between the contact part and the magnetic circuit part, and replaces the insulated connection between the contact part and the magnetic circuit part through integral injection molding of the pusher. This changes the assembly method of integral injection molding and solves a series of drawbacks brought about by integral injection molding, such as high cost and long processing cycle.

[0047] To make the above-mentioned objectives, features, and advantages of this application more apparent and understandable, the specific embodiments of this application are described in detail below with reference to the accompanying drawings. Many specific details are set forth in the following description to provide a thorough understanding of this application. However, this application can be implemented in many other ways different from those described herein, and those skilled in the art can make similar modifications without departing from the spirit of this application. Therefore, this application is not limited to the specific embodiments disclosed below.

[0048] In the description of this application, it should be understood that if terms such as "center", "longitudinal", "lateral", "length", "width", "thickness", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", "clockwise", "counterclockwise", "axial", "radial", "circumferential" appear, these terms indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, and are only for the convenience of describing this application 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, and therefore should not be construed as a limitation of this application.

[0049] Furthermore, where the terms "first" and "second" appear, these terms are for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined with "first" or "second" may explicitly or implicitly include at least one of that feature. In the description of this application, where the term "multiple" appears, "multiple" means at least two, such as two, three, etc., unless otherwise explicitly specified.

[0050] In this application, unless otherwise expressly specified and limited, the terms "installation," "connection," "joining," and "fixing," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components, unless otherwise expressly limited. Those skilled in the art can understand the specific meaning of the above terms in this application based on the specific circumstances.

[0051] In this application, unless otherwise expressly specified and limited, the use of descriptions such as "above" or "below" the second feature indicates that the first and second features are in direct contact or indirect contact via an intermediate medium. Furthermore, "above," "on top of," and "over" the second feature can mean that the first feature is directly above or diagonally above the second feature, or simply that the first feature is at a higher horizontal level than the second feature. Similarly, "below," "below," and "under" the second feature can mean that the first feature is directly below or diagonally below the second feature, or simply that the first feature is at a lower horizontal level than the second feature.

[0052] It should be noted that if an element is referred to as being "fixed to" or "set on" another element, it can be directly on the other element or there may be an intervening element. If an element is considered to be "connected to" another element, it can be directly connected to the other element or there may be an intervening element. If so, the terms "vertical," "horizontal," "upper," "lower," "left," "right," and similar expressions used in this application are for illustrative purposes only and do not represent the only possible implementation.

[0053] See Figure 1As shown, this application provides a relay. At the transmission level inside the relay, the relay includes at least a transmission component 1000, a magnetic circuit portion 2000, and a contact portion 3000. The contact portion 3000 serves as the high-voltage terminal of the relay, and the magnetic circuit portion 2000 serves as the low-voltage terminal. The magnetic circuit portion 2000 includes a magnetic circuit actuating element 2010, and the contact portion 3000 includes an insulating mounting base 3010. Between the magnetic circuit portion 2000 and the contact portion 3000, the transmission component 1000 includes a main body portion 1100 and a first connecting portion 1200 and a second connecting portion 1300 disposed on the main body portion 1100. The magnetic circuit actuating element 2010 can be connected to the first connecting portion 1200, and the insulating mounting base 3010 can be connected to the second connecting portion 1300.

[0054] Therefore, this application changes the existing relay method where the contact part 3000 and the magnetic circuit part 2000 are integrally injection molded and insulated. Instead, it uses a transmission component 1000 to indirectly connect the contact part 3000 and the magnetic circuit part 2000. The transmission component 1000 achieves the connection between the contact part 3000 and the magnetic circuit part 2000, and replaces the integral injection molding connection between the contact part 3000 and the magnetic circuit part 2000 with the transmission component 1000. This changes the integral injection molding assembly method and solves a series of drawbacks of the integral injection molding method, such as high cost and long processing cycle.

[0055] In one embodiment of the above-mentioned scheme in which the transmission component 1000 indirectly connects the contact portion 3000 and the magnetic circuit portion 2000, the magnetic circuit actuating element 2010 can be detachably connected to the first connecting portion 1200, and the insulating mounting base 3010 can be detachably connected to the second connecting portion 1300. Therefore, the difference between the way the transmission component 1000 connects the contact portion 3000 and the magnetic circuit portion 2000 and the one-piece injection molding can be more clearly demonstrated. Moreover, the detachable connection method can also facilitate assembly and disassembly, making it more flexible.

[0056] The transmission component 1000 can be configured as a metal part connecting the magnetic circuit part 2000 and the contact part 3000, and is made of metal. Since metal has a certain degree of elasticity, it is easier to assemble and operate, and its hardness is better, making the connection strength more reliable.

[0057] Alternatively, in one embodiment, the transmission component 1000 may also be configured as an insulating element connecting the magnetic circuit portion 2000 and the contact portion 3000, and thus, by using an insulating material, the transmission component 1000 and the insulating mounting base 3010 can be integrally formed, which can save assembly steps, reduce weight, and increase the insulation creepage distance between high and low voltage. Therefore, those skilled in the art can select a suitable structural design to complete the connection between the contact portion 3000 and the magnetic circuit portion 2000 via the transmission component 1000 according to actual needs, and no limitation is made here.

[0058] The main body 1100, the first connecting portion 1200, and the second connecting portion 1300 of the transmission component 1000 can be specifically designed according to the specific structural design and relative assembly relationship of the contact portion 3000 and the magnetic circuit portion 2000. For example, in one embodiment, see [reference]. Figure 2 As shown, the main body 1100 may include a first plate 1110 and a second plate 1120. The first plate 1110 is connected to the second plate 1120, and the first plate 1110 and the second plate 1120 are designed with a suitable relative tilt angle according to the connection requirements. Moreover, in one embodiment, the number of first plates 1110 may be configured to be two, and the two first plates 1110 are symmetrically arranged on both sides of the second plate 1120, resulting in more even force distribution and more stable connection.

[0059] In addition, those skilled in the art can design the number and relative spatial relationship of the first plate 1110 and the second plate 1120 according to actual needs, thereby satisfying the connection between the contact part 3000 and the magnetic circuit part 2000, such as ring fit, increasing the number, etc., which are not limited here.

[0060] In the above embodiments, the first plate 1110 may be provided with a first connecting portion 1200, which is detachably connected to the magnetic circuit actuating member 2010. The second plate 1120 may be provided with a second connecting portion 1300, which is detachably connected to the insulating mounting base 3010. The first connecting portion 1200 and the second connecting portion 1300 may be designed as various structures with connecting functions, such as hole structures, protrusion structures, snap-fit ​​structures, threaded structures, etc., and are not limited here.

[0061] See Figure 2 As shown, in one embodiment, the first plate 1110 may have a first insertion hole, which is configured as a first connecting part 1200. The magnetic circuit actuator 2010 may be configured with a first insertion part 2100 adapted according to the shape, size and other design factors of the first insertion hole, so that the first insertion hole can be fitted onto the first insertion part 2100 of the magnetic circuit actuator 2010, thereby completing the hole insertion assembly.

[0062] The first plate 1110 extends along the movement direction of the magnetic circuit actuator 2010, and the second plate 1120 is perpendicular to the movement direction of the magnetic circuit actuator 2010. The first connecting portion 1200 on the first plate 1110 has two limiting surfaces arranged along the movement direction of the magnetic circuit actuator 2010, used to limit the two surfaces of the magnetic circuit actuator 2010 along its movement direction. Since the magnetic circuit actuator 2010 reciprocates along its movement direction when the relay is working, limiting the two surfaces of the magnetic circuit actuator 2010 along its movement direction with two limiting surfaces effectively improves the anti-disengagement limiting effect, making the assembly structure more reliable. The second plate 1120 being perpendicular to the movement direction makes the contact more stable and the force distribution more uniform and reliable.

[0063] Similarly, the second plate 1120 may have a second insertion hole, which is configured as a second connecting part 1300. The insulating mounting base 3010 may be configured with a matching second insertion part 3100 according to the shape, size and other design factors of the second insertion hole, so that the second insertion hole is fitted onto the second insertion part 3100 of the insulating mounting base 3010, thereby completing the hole insertion assembly.

[0064] In one embodiment, each first plate 1110 may have the aforementioned first insertion hole, and the magnetic circuit actuator 2010 may have two matching first insertion portions 2100 provided according to the position and number of the first insertion holes, so that the first insertion holes of the two first plates 1110 are respectively fitted onto different first insertion portions 2100 in the magnetic circuit actuator 2010. The two first insertion holes and the two first insertion portions 2100 are connected at different positions in the magnetic circuit actuator 2010, which can improve the stability of the assembly.

[0065] Especially Figure 2 As shown, the two first insertion holes are connected to the two first insertion parts 2100 on opposite sides of the magnetic circuit actuator 2010. This not only improves assembly stability by increasing the number of holes, but also creates a clamping or locking effect on the magnetic circuit actuator 2010 from both sides of the magnetic circuit actuator 2010 by connecting the two first insertion parts 2100 at the two first insertion holes on both sides of the magnetic circuit actuator 2010, thereby further improving assembly stability.

[0066] like Figure 1As shown, the space between the two first plates 1110 and the second plate 1120 is configured as a receiving space 1111. The receiving space 1111 is configured to receive part of the structure of the magnetic circuit actuator 2010. So, after the two first plates 1110 and the second plate 1120 receive part of the structure of the magnetic circuit actuator 2010 in the receiving space 1111, they are connected to the two first plug-in parts 2100 on both sides of the magnetic circuit actuator 2010 through the two first plug-in holes. This forms a clamping or locking effect on the magnetic circuit actuator 2010 on both sides and receives part of the structure of the magnetic circuit actuator 2010, thereby further improving the assembly stability.

[0067] The magnetic circuit actuator 2010 includes a magnetic guide plate 2300, and a first insertion portion 2100 is disposed on the magnetic guide plate 2300. The first insertion portion 2100 is coplanar with the magnetic guide plate 2300, or the first insertion portion 2100 is located on the side of the magnetic guide plate 2300 away from the contact portion 3000. Therefore, by utilizing the original height space of the magnetic circuit actuator 2010 to set the first insertion portion 2100, the additional space occupied by the first insertion portion 2100 in the height direction can be reduced, resulting in a more compact structure.

[0068] Continue reading Figure 3 and Figure 4 As shown, in one embodiment, the second insertion portion 3100 may also be provided with an insertion extension portion 3200. At least a portion of the structure of the insertion extension portion 3200 is located between the second plate 1120 and the magnetic circuit actuator 2010. Therefore, the insertion extension portion 3200 can be used to limit the relative height of the second plate 1120 and the magnetic circuit actuator 2010, so that after the second plate 1120 and the magnetic circuit actuator 2010 are connected to each other, the second plate 1120 and the magnetic circuit actuator 2010 can form a limiting effect in the height direction.

[0069] For example, when the magnetic circuit actuator 2010 includes a magnetic guide plate 2300, the first insertion part 2100 can be disposed on the magnetic guide plate 2300, and there is a certain distance between the second plate 1120 and the magnetic guide plate 2300. This distance is designed to be approximately equal to the height of the insertion extension 3200, thereby clamping the insertion extension 3200 between the second plate 1120 and the magnetic guide plate 2300, so that the contact part 3000 and the magnetic circuit actuator 2010 are relatively stationary in the direction of movement (height) to ensure the stability of the connection.

[0070] The plug-in extension 3200 and the second plug-in portion 3100 can be configured as an integral structure or a separate structure. Those skilled in the art can also design according to actual needs, which is not limited here.

[0071] In addition to fulfilling the function of connection, the insertion assembly between the second insertion hole and the second insertion part 3100 can also be designed with other functions as needed. For example, in one embodiment, the second insertion hole can be configured as an irregular hole and the second insertion part 3100 can be configured as an irregular post. The irregular hole and irregular post are different from regular round holes and cylinders. When the second insertion hole and the second insertion part 3100 are inserted into each other, the irregular design between the second insertion hole and the second insertion part 3100 cannot form a smooth rotation like a round hole or cylinder. Therefore, it can be used to restrict the relative rotation between the second insertion hole and the second insertion part 3100, thereby ensuring the stability of the connection.

[0072] In addition, the anti-rotation limiting function can also be designed in other locations. For example, in one embodiment, at least one of the magnetic circuit actuator 2010 and the second insertion portion 3100 can be provided with an anti-rotation body 3300 for preventing rotation. Figure 5 The diagram illustrates an anti-rotation element 3300 located in the second insertion portion 3100. When the magnetic circuit actuator 2010 is equipped with the anti-rotation element 3300, it can be used after assembly to engage with the rotationally limited portion 3100 for rotational limiting. When the second insertion portion 3100 is equipped with the anti-rotation element 3300, it can be used after assembly to engage with the insertion extension portion 3200 for rotational limiting. Alternatively, both the magnetic circuit actuator 2010 and the second insertion portion 3100 can be equipped with anti-rotation elements 3300 to prevent rotation, thus forming a bidirectional rotational limiting engagement through the two parallel methods mentioned above. Those skilled in the art can also design such engagements according to actual needs, which are not limited here.

[0073] Continue reading Figure 6 As shown, in one embodiment, the magnetic circuit part 2000 further includes a coil, an inner yoke 2500, an outer yoke 2600, and two permanent magnets 2700. The magnetic circuit actuator 2010 includes an iron core 2200 and a magnetic guide plate 2300. The iron core 2200 is disposed in the coil, and both ends of the iron core 2200 are connected to the two magnetic guide plates 2300. The inner yoke 2500 is disposed in the outer yoke 2600. The two magnetic guide plates 2300 are respectively disposed between the inner yoke 2500 and the outer yoke 2600, and there is a movable gap between them. The two permanent magnets 2700 are symmetrically disposed between the inner yoke 2500 and the outer yoke 2600 with the iron core 2200 as the axis.

[0074] In one embodiment, an anti-rotation structure 2400 may also be provided between the iron core 2200 and the magnetic plate 2300. This anti-rotation structure 2400 can be configured to limit relative rotation between the iron core 2200 and the magnetic plate 2300. The anti-rotation structure 2400 can be constructed using various structures with anti-rotation functions. For example, in one embodiment, the anti-rotation structure 2400 may include a first anti-rotation part 2410 and a second anti-rotation part 2420. The first anti-rotation part 2410 is disposed in the iron core 2200, and the second anti-rotation part 2420 is disposed in at least one of the magnetic plate 2300 and the coil frame. Therefore, after assembly, the first anti-rotation part 2410 and the second anti-rotation part 2420 can be connected, and this connection can be used to limit relative rotation of the iron core 2200 relative to at least one of the magnetic plate 2300 and the coil frame.

[0075] Regarding the aforementioned first anti-rotation part 2410 and second anti-rotation part 2420, in one embodiment, the first anti-rotation part 2410 may be configured as an anti-rotation hole formed in the magnetic guide plate 2300, and the second anti-rotation part 2420 may be configured as an anti-rotation protrusion provided in the iron core 2200. In this case, the inner wall of the anti-rotation hole is provided with one or more first anti-rotation surfaces 2411, and the outer wall of the anti-rotation protrusion is provided with one or more second anti-rotation surfaces 2421. The first anti-rotation surfaces 2411 and the second anti-rotation surfaces 2421 need to be mutually matched. Therefore, after the anti-rotation protrusion is fitted into the anti-rotation hole, each first anti-rotation surface 2411 can be limited and fitted with a matching second anti-rotation surface 2421. This mutual fitting between surfaces is used to prevent relative rotation between the iron core 2200 and the magnetic guide plate 2300. The number, shape, and size of the first anti-rotation surfaces 2411 and the second anti-rotation surfaces 2421 are not limited here; those skilled in the art can design them according to actual needs.

[0076] Alternatively, in one embodiment, the first anti-rotation part 2410 may be configured as an anti-rotation hole in the coil frame, the inner wall of the anti-rotation hole is provided with one or more protrusions, and the outer wall of the iron core 2200 is provided with one or more anti-rotation grooves. When the protrusions are fitted into the anti-rotation grooves, they can be locked together by interlocking, thereby limiting the relative rotation of the iron core 2200 and the coil frame.

[0077] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0078] The embodiments described above are merely illustrative of several implementation methods of this application, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the patent application. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this application, and these all fall within the protection scope of this application. Therefore, the protection scope of this patent application should be determined by the appended claims.
