Description

Technical Field

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

[0002] With the evolution of technologies such as fifth-generation mobile communication, the performance requirements of high-frequency relays in communication base stations and testing equipment are becoming increasingly stringent. They are required not only to be able to stably switch high-power high-frequency signal loads, but also to meet the needs of high-density integration of equipment for miniaturization and surface mounting of high-frequency relays.

[0003] Especially in high-frequency relays, to ensure the quality of high-frequency signal transmission, a shielding cover is usually installed around the signal transmission path and grounded to create a controllable electromagnetic shielding environment. However, within the limited space of an ultra-miniature high-frequency relay, the physical distance between the metal components such as the iron core and armature in the electromagnetic part and the high-frequency signal contact part is extremely compressed. Furthermore, to meet the assembly and functional layout requirements of the high-frequency relay, the shielding cover needs to have clearance holes or slots to accommodate surrounding components. For example, clearance structures are provided in the shielding cover to accommodate components such as the push rod of the moving spring assembly and the lead-out end of the stationary spring, resulting in the high-frequency signal contact part not being completely enclosed by the shielding cover. Due to their functional and structural characteristics, the metal components in the electromagnetic part will induce and accumulate charges under the influence of the high-frequency electromagnetic field. These charges, through the clearance structures of the shielding cover, severely interfere with the adjacent contact parts, thereby causing uncontrollable coupling and crosstalk to the high-frequency signal transmitted in the contact parts, leading to decreased signal integrity and increased insertion loss. Summary of the Invention

[0004] Therefore, it is necessary to provide a high-frequency relay to address the problem of uncontrollable coupling and crosstalk between the electromagnetic part and the high-frequency signal transmitted to the contact part in current high-frequency relays.

[0025] In one embodiment, the electromagnetic portion includes:

[0026] A coil support, wherein the iron core is disposed on the coil support, and at least a portion of the end face of the iron core connected to the conductive connector is exposed on the coil support;

[0027] An armature assembly is located on one side of the coil support along the first direction and is disposed close to the moving spring assembly; the armature assembly is configured to rotate relative to the iron core such that one end of the armature assembly contacts the iron core and the other end is separated from the iron core.

[0028] In one embodiment, the two end faces of the iron core that are furthest apart along the second direction are each connected to a conductive connector;

[0029] The armature assembly and the moving spring assembly are located in the area between the two conductive connectors;

[0043] The aforementioned high-frequency relay, by setting a conductive connector connecting the metal parts of the electromagnetic component and the shield, wherein the conductive connector is grounded through the grounding terminal of the shield, provides a grounding path for the metal parts in the electromagnetic component. This eliminates the parasitic coupling and secondary radiation effects caused by the proximity of the metal parts in the electromagnetic component to the high-frequency operating contact parts, thereby reducing the crosstalk and interference coupling of the electromagnetic component to the high-frequency signals of the contact parts, and thus ensuring the integrity and transmission efficiency of the high-frequency signals.

[0044] Furthermore, the conductive connector in this embodiment enables the metal components of the electromagnetic part to be grounded together with the shielding cover, thereby transforming it into a structure with shielding function. This forms a double shield with the shielding cover, which is beneficial to improving the overall electromagnetic shielding effectiveness of the high-frequency relay.

[0045] In addition, the conductive connectors and shielding covers in this embodiment are usually made of metal, which has good thermal conductivity. The conductive connectors conduct heat from the electromagnetic part to the shielding cover, and then quickly conduct it to the outside of the high-frequency relay through the grounding terminal of the shielding cover. This reduces the temperature rise of the coil of the electromagnetic part, which is conducive to the normal or efficient operation of the coil current and electromagnetic attraction, improves the reliability of operation and contact reliability, and thus helps to reduce the contact resistance. At the same time, this arrangement helps to stabilize the distributed resistance and distributed inductance of the contact part (high-frequency transmission part), thereby ensuring the stability of high-frequency signal transmission and reducing insertion loss.

[0071] 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.

[0072] 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.

[0073] 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.

[0074] 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.

[0075] 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.

[0076] 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.

[0077] As described in the background section, during operation, when the contact portion transmits high-frequency signals, leakage or scattering of high-frequency electromagnetic fields inevitably occurs around it. These adjacent magnetic circuit metal components, especially their non-smooth structures such as edges and corners formed due to processing or structural requirements, create complex parasitic capacitances and inductive structures, significantly coupling the high-frequency electric field energy scattered by the contact portion. This coupling effect leads to at least the following problems:

[0078] For example, high-frequency energy coupled to the metal components of the magnetic circuit exists in the form of induced current and accumulated charge. This metal component acts as a secondary radiation source, scattering high-frequency electromagnetic waves again into the surrounding space (including the contact area). This causes crosstalk and interference coupling to the high-frequency signal that should be transmitted purely in the contact area, leading to signal distortion and reduced transmission efficiency. Furthermore, this unintended coupling and dissipation of energy increases the equivalent loss along the signal transmission path. This lost energy is ultimately converted into heat, causing the temperature of the contact area and surrounding components to rise, further deteriorating parameters such as contact resistance, creating a vicious cycle that ultimately limits the high-frequency signal transmission capability and operational reliability of the high-frequency relay. Additionally, some high-frequency energy parasitizes the metal components and is converted into heat, exacerbating the temperature rise of the contact area and coil. This temperature rise reduces the magnetic field strength generated by the coil and further deteriorates high-frequency transmission performance, creating negative feedback and ultimately affecting the operational stability and reliability of the high-frequency relay in high-power, high-frequency scenarios.

[0079] Based on the aforementioned problems, the high-frequency relay provided in this application provides a grounding path for the metal components in the electromagnetic part by setting a conductive connector that connects the metal components in the electromagnetic part and the shielding cover. The conductive connector is grounded through the grounding terminal of the shielding cover, thereby eliminating the parasitic coupling and secondary radiation effects caused by the metal components in the electromagnetic part being close to the high-frequency operating contact parts. This reduces the crosstalk and interference coupling of the electromagnetic part to the high-frequency signals of the contact parts, thereby ensuring the integrity and transmission efficiency of the high-frequency signals.

[0080] Furthermore, the conductive connector in this embodiment enables the metal components of the electromagnetic part to be grounded together with the shielding cover, thereby transforming it into a structure with shielding function. This forms a double shield with the shielding cover, which is beneficial to improving the overall electromagnetic shielding effectiveness of the high-frequency relay.

[0081] In addition, the conductive connectors and shielding covers in this embodiment are typically made of metal, which has good thermal conductivity. The conductive connectors conduct heat from the electromagnetic components to the shielding cover, and then quickly conduct it to the outside of the high-frequency relay through the grounding terminal of the shielding cover. This reduces the temperature rise of the coil in the electromagnetic components, which is beneficial for the normal or efficient operation of the coil current and electromagnetic attraction. The electromagnetic attraction on the armature can reliably maintain the armature and the iron core, improving the reliability of operation and contact contact, and thus helping to reduce the contact resistance. At the same time, this arrangement helps to stabilize the distributed resistance and distributed inductance of the contact part (high-frequency transmission part), thereby ensuring the stability of high-frequency signal transmission, reducing insertion loss, and ultimately ensuring the working stability and reliability of the high-frequency relay in high-power, high-frequency scenarios.

[0082] See Figures 1 to 3 , Figure 1 This is a schematic diagram of the overall structure of a high-frequency relay provided according to some embodiments of this application. Figure 2 This is a schematic diagram of the disassembly structure of a high-frequency relay provided according to some embodiments of this application. Figure 3 This is a disassembled structural diagram of a high-frequency relay according to some embodiments of this application, with the outer casing removed. One embodiment of this application provides a high-frequency relay, particularly a high-frequency relay suitable for transmitting and switching high-frequency signals, characterized by high power and small size. The high-frequency relay may include an electromagnetic part 20, a contact part 30, a shielding cover 50, and a conductive connector 40.

[0083] The electromagnetic part 20 includes a plurality of metal components 21; a contact part 30 is disposed on one side of the electromagnetic part 20 along a first direction, the contact part 30 including a moving spring assembly 31 and a stationary spring 32; a shielding cover 50 is disposed on the side of the stationary spring 32 facing the electromagnetic part 20; at least a portion of the stationary spring 32 is located inside the shielding cover 50, and at least a portion of the moving spring assembly 31 is located inside the shielding cover 50; wherein, the shielding cover 50 is provided with a grounding terminal for grounding; one end of the conductive connector 40 is electrically connected to at least one of the plurality of metal components 21, and the other end is electrically connected to the shielding cover 50.

[0084] It is understood that the high-frequency relay in this embodiment adopts a stacked layout as a whole in order to optimize the use of internal space while achieving miniaturization and low-profile packaging.

[0085] Specifically, the electromagnetic part 20 serves as the driving source for the high-frequency relay, converting input electrical energy into kinetic energy to drive the contact part 30 to switch states. In this example, the electromagnetic part 20 includes multiple metal components 21. Exemplarily, these metal components 21 can be made of a material with good magnetic permeability to form a low magnetic reluctance magnetic circuit.

[0086] More specifically, in this embodiment, the electromagnetic part 20 may include a coil assembly, an iron core 212, and an armature 231. The coil assembly includes a coil frame (hereinafter referred to as the coil support) and a coil wound on the coil frame. The coil frame is typically made of insulating material and has a cavity extending along its length; the coil on it generates a driving magnetic field when energized. The iron core 212 passes through the cavity of the coil frame. In one example, the iron core 212 is U-shaped or approximately U-shaped and has two pole faces spaced apart horizontally. In this example, the iron core 212 can collect and guide the magnetic flux generated by the coil and generate an attractive force on the armature 231 at its pole faces.

[0087] In some alternative examples, the armature 231 can rotate in a seesaw-like motion around a pivot or fulcrum, thereby contacting one of the two pole faces of the core 212. In other words, the armature 231 can be attracted by one pole face of the core 212 under the influence of a magnetic field, thus causing it to rotate. Of course, the armature assembly includes the armature 231 and an elastic retaining member (hereinafter referred to as the compression spring 232). The compression spring 232 is fixed to the armature 231 and is disposed away from the core 212, and can transmit the rotational motion of the armature 231 to the contact portion 30.

[0088] In some examples, the first direction is defined as the vertical direction. In this embodiment, the contact portion 30 is disposed on one side of the electromagnetic portion 20 along the first direction, for example, below. The contact portion 30 is mainly used to connect or disconnect the external load circuit. In this example, the contact portion 30 includes a moving spring assembly 31 and a stationary spring 32.

[0089] Specifically, the stationary spring 32 serves as a fixed component, its position being stationary relative to the base of the high-frequency relay. The stationary spring 32 includes at least one stationary spring sheet and a stationary contact disposed on the spring sheet. The spring sheet is made of conductive material, with one end serving as a lead for soldering to an external circuit (e.g., a PCB board), and the other end extending into the high-frequency relay and fixed to the stationary contact. Exemplarily, the stationary spring 32 includes a common terminal (COM) stationary spring, a normally open terminal (NO) stationary spring, and a normally closed terminal (NC) stationary spring to achieve a single-pole double-throw function.

[0090] In some alternative examples, the moving spring assembly 31 is a movable part that can move up and down along a first direction. The moving spring assembly 31 includes a driving member and a moving spring plate. The driving member can move under the action of the compression spring 232, thereby driving the moving spring plate to contact or separate from the stationary contact of the corresponding stationary spring member 32, so as to realize the circuit connection or disconnection.

[0091] In this example, the shield 50 is located on the side of the stationary spring 32 facing the electromagnetic part 20; in other words, the shield 50 is located between the electromagnetic part 20 and the contact part 30. The shield 50 in this example is made of conductive material and is used to connect to ground potential under normal operating conditions to shield the high-frequency signal transmission path. Exemplarily, the end of the shield 50 located outside the high-frequency relay is the ground terminal.

[0092] Specifically, in this example, at least a portion of the stationary spring 32 is located within the shielding cover 50 to be electromagnetically shielded by the shielding cover 50. The drive member of the aforementioned moving spring assembly 31 passes through the shielding cover 50, allowing the moving spring to move up and down within the space defined by the shielding cover 50 and to contact or separate from the stationary contact within that space.

[0093] In this embodiment, the conductive connector 40 serves as an independent connecting component. One end of it is electrically connected to at least one of the multiple metal components 21 of the electromagnetic part 20, and the other end is electrically connected to the shielding cover 50. The grounding is achieved through the shielding cover 50.

[0094] It is important to understand that in traditional high-frequency relay structures, the metal components 21 in the electromagnetic part 20 (including the aforementioned iron core 212, armature 231, compression spring 232, etc.) are not connected to any fixed potential. The inventors of this application discovered that under high-frequency operating conditions, these electrically suspended metal components 21 can become secondary radiation sources, significantly impacting the quality of high-frequency signal transmission. However, by using the conductive connector 40, the originally suspended metal components 21 can be placed at the same ground potential as the shield 50. This arrangement provides a low-impedance discharge path for the charge or current accumulated on the metal components 21 due to high-frequency electric field induction, thereby eliminating the basis for these metal components 21 to act as secondary radiation sources and fundamentally suppressing their crosstalk and coupling to the high-frequency signals of the contact part 30.

[0095] In some alternative examples, the conductive connector 40 can be made of a conductive but non-magnetic metal material to ensure stable and reliable operation of the high-frequency relay. Since the conductive connector 40 connects to metal components 21 such as the iron core 212, or is itself a magnetic material, it will disperse, for example, the magnetic flux between the iron core 212 and the armature 231, thereby reducing the efficiency of the magnetic circuit and the stability of the driving force.

[0096] The connection between the conductive connector 40 and the metal part 21 and the shielding cover 50 can be achieved by welding. Of course, the conductive connector 40 and the metal part 21, or the shielding cover 50, can be pre-positioned before welding to improve assembly efficiency. The specific positioning and fixing methods can be understood by referring to the following examples.

[0097] Through the above structure, a metal component 21 is grounded by being electrically connected to the shield 50 via the conductive connector 40. Since the metal components in the electromagnetic section 20 are interconnected, other metal components 21 in the magnetic circuit section 20 can be indirectly grounded using the existing grounding function of the shield 50 of the high-frequency relay, eliminating the need for a separate grounding lead for each metal component 21. For example, the iron core 212 is connected to the conductive connector 40. In the stable operating state of the high-frequency relay, the armature 231, due to magnetic attraction and / or reset force, always maintains contact with the iron core 212 at one end, and this contact itself constitutes an electrical connection. Therefore, when the iron core 212 is grounded through the conductive connector 40, the armature 231 is ultimately connected to ground potential through the iron core 212, the conductive connector 40, and the shield 50. This design greatly simplifies the internal structure and assembly process of the high-frequency relay.

[0098] It should be noted that in this example, the conductive connector 40 can be directly connected to the iron core 212 of the electromagnetic part 20, or it can be connected to the armature 231 instead of the iron core 212, or it can be connected to other metal parts 21. No restrictions are placed here.

[0099] In some alternative examples, the conductive connector 40 can be a metal component to form an additional reinforcing structure between the electromagnetic portion 20 and the contact portion 30, enhancing the overall connection rigidity. Alternatively, the conductive connector 40 can be a flexible wire or conductive braid to eliminate the stress effects present in the assembly dimensions.

[0100] In some embodiments, the above structure is combined, such as Figure 7 As shown, the working process of the high-frequency relay in this embodiment can be described as follows:

[0101] like Figure 7 and Figure 8 As shown, when the coil is supplied with rated current, the iron core 212 generates electromagnetic attraction, attracting one end of the armature 231, causing the other end of the armature 231 to rotate (clockwise rotation in the figure) against the reaction force of the spring return member 312. In this embodiment, the high-frequency relay structure also includes two moving spring assemblies 31, spaced apart along the second direction; and two spring return members 321 corresponding to the two moving spring assemblies 31. The rotation of the armature 231 drives the compression spring 232 fixed thereon to move. The left end of the armature 231 contacts the left end pole face of the iron core 212, while the right end of the armature 231 separates from the right end pole face of the iron core 212. The right end of the compression spring 232 presses down on the right moving spring assembly 31, forcing the right moving spring to move downwards. The right moving spring contacts the right stationary spring, while the left moving spring separates from the left stationary spring, thereby switching the on / off state of the contacts and completing the switching of the signal channel. When the current flowing through the coil is in the opposite direction, the iron core 212 will attract the armature 231 to rotate counterclockwise. The left end of the armature 231 will separate from the left end pole face of the iron core 212, and the right end of the armature 231 will contact the right end pole face of the iron core 212.

[0102] Therefore, throughout the entire operation, whether the armature 231 rotates clockwise or counterclockwise, the conductive connector 40 always maintains the iron core 212, armature 231, and compression spring 232 at the same ground potential as the shield 50. When the contact portion 30 transmits high-frequency signals, even if the high-frequency electromagnetic field leaking or scattering around it acts on these magnetic circuit metal components 21, it will not be able to establish a significant potential difference or accumulate charge on their surface because the metal components 21 are already grounded. Any tiny current induced will be quickly and directly discharged to the shield 50 through the low-impedance path provided by the conductive connector 40. Therefore, these metal components 21 cannot form effective secondary radiation, and their crosstalk and interference coupling paths to the high-frequency signals of the contact portion 30 are effectively cut off.

[0103] In summary, the high-frequency relay provided in this application provides a grounding path for the metal component 21 in the electromagnetic part 20 by setting a conductive connector 40 connecting the metal component 21 of the electromagnetic part 20 and the shield 50. The conductive connector is grounded through the grounding terminal of the shield, thereby eliminating the parasitic coupling and secondary radiation effects generated by the metal component in the electromagnetic part 20 due to its proximity to the high-frequency operating contact part 30. This reduces the crosstalk and interference coupling of the electromagnetic part 20 to the high-frequency signal of the contact part 30, thereby ensuring the integrity and transmission efficiency of the high-frequency signal.

[0104] Furthermore, in this embodiment, the conductive connector 40 enables the metal component 21 of the electromagnetic part 20 and the shielding cover 50 to be grounded together, thereby transforming it into a structure with shielding function and forming a double shield with the shielding cover 50, which is beneficial to improving the overall electromagnetic shielding effectiveness of the high-frequency relay.

[0105] In addition, the conductive connector 40 and shield 50 in this embodiment are usually made of metal, which has good thermal conductivity. The conductive connector conducts the heat of the electromagnetic part to the shield and then quickly conducts it to the outside of the high-frequency relay through the grounding terminal of the shield, thereby reducing the temperature rise of the coil of the electromagnetic part. This is beneficial to the normal or efficient operation of the coil current and electromagnetic attraction, improving the reliability of operation and contact contact, and thus helping to reduce the contact resistance. At the same time, this arrangement is conducive to the stability of the distributed resistance and distributed inductance of the contact part (high-frequency transmission part), thereby ensuring the stability of high-frequency signal transmission and reducing insertion loss.

[0106] Below, we will combine the appendix Figure 1 To be continued Figure 17 The specific structure of the high-frequency relay provided in the embodiments of this application will be described in detail.

[0107] In some embodiments, the conductive connector 40 is tightly fitted between one of the metal components 21 and the shield 50.

[0108] Specifically, the tight fit in this example can be understood as an assembly method that achieves fixation and electrical connection through its own elastic deformation or structural interference, enabling a preliminary and reliable connection. For example, the conductive connector 40 can be made of an elastic metal sheet with a U-shaped or C-shaped structure. The conductive connector 40 can deform under external force and then enter the space formed by the metal component 21 and the shield 50. As the external force disappears, the conductive connector 40 returns to its original shape, thereby abutting against the adjacent metal component 21 and shield 50, achieving preliminary positioning. Finally, the fixed connection between the conductive connector 40 and the metal component 21 and shield 50 can be achieved by conductive adhesive, welding, or other methods.

[0109] In this embodiment, the conductive connector 40 can be pre-fixed in a simple assembly process, reducing assembly steps and time, thereby lowering manufacturing costs and improving overall production efficiency. Furthermore, this initial fixing of the conductive connector 40 facilitates subsequent welding processes, including eliminating the need for additional clamps to hold the conductive connector 40 in position during laser welding, enabling precise welding.

[0110] In some embodiments, the conductive connector 40 is configured as a deformable element, and the deformation direction of the conductive connector 40 is consistent with the first direction. Specifically, since the electromagnetic portion 20 and the contact portion 30 are stacked along the first direction, and in order to absorb the manufacturing and assembly tolerances of the high-frequency relay along the stacking direction, this example designs the conductive connector 40 as a deformable element, and the main deformation direction is consistent with the first direction.

[0111] Furthermore, the deformable element in this example can be understood as the conductive connector 40 including at least a flexible segment or elastic element in its structure, so that its overall dimension in the first direction can undergo reversible elastic change within a certain range. For example, from the side view direction (e.g.) Figure 7 Viewed from the indicated direction, the conductive connector 40 can have a C-shape, S-shape, Z-shape, or multiple continuous curved structures. Alternatively, the end of the conductive connector 40 used to connect with the shield 50 can be designed as an elastic cantilever that is inclined at an angle to the first direction and tilted toward the shield.

[0112] Regardless of the shape of the conductive connector 40, in its free state, the dimension of the conductive connector 40 along the first direction is h1; after being assembled to the metal part 21 and the shield 50, the conductive connector 40 is deformed, and its dimension along the first direction is h2, and h2 is less than h1.

[0113] In this embodiment, the design of the deformable conductive connector 40 not only compensates for or absorbs the cumulative manufacturing tolerances and assembly errors of the electromagnetic part 20 and the shield 50 in the height direction through its own deformation, avoiding the problem of over-positioning or internal stress caused by introducing rigid parts with invariable dimensions; but also, the conductive connector 40 has an elastic tendency to recover its deformation after assembly, and can continuously apply contact pressure to the metal part 21 and the shield 50. With external factors such as temperature changes or mechanical vibrations, this contact pressure can ensure that the conductive connector 40 will not become loose and have poor contact, thus ensuring the stability and reliability of its low-impedance grounding path.

[0114] In some embodiments, such as Figure 3As shown, the conductive connector 40 is provided with a first positioning part 41, and one of the metal parts 21 is provided with a second positioning part 211. The first positioning part 41 and the second positioning part 211 are connected to each other to restrict the conductive connector 40 to a preset position of the metal part 21.

[0115] It is understandable that the first positioning part 41 and the second positioning part 211 are provided to achieve the installation and positioning of the conductive connector 40, so as to improve the assembly accuracy and connection reliability of the conductive connector 40. For example, if the first positioning part 41 is a through hole provided on the conductive connector 40, then the second positioning part 211 is a protrusion provided on the side of the metal component 21 (e.g., iron core 212), and the shape and size of the protrusion are adapted to the through hole; during assembly, the operator only needs to align the through hole of the conductive connector 40 and fit it onto the protrusion of the iron core 212 to quickly and accurately complete the positioning of the conductive connector 40. As another example, if the first positioning part 41 is a groove provided on the edge of the conductive connector 40, and the second positioning part 211 is a flange or step provided on the iron core 212, during assembly, by engaging the groove of the conductive connector 40 onto the flange of the iron core 212, the freedom of the conductive connector 40 in at least two directions can be restricted.

[0116] This embodiment, through the docking of the first positioning part 41 and the second positioning part 211, provides a definite position and orientation for the installation of the conductive connector 40, improving installation accuracy and simplifying assembly operations, thereby increasing production efficiency. Furthermore, it prevents displacement of the conductive connector 40 in subsequent processes, thus ensuring the quality of subsequent processes such as welding.

[0117] In some embodiments, such as Figure 3 As shown, the first positioning part 41 includes a plurality of first positioning sub-parts, and the second positioning part 211 includes a plurality of second positioning sub-parts corresponding to the plurality of first positioning sub-parts. The first positioning sub-parts and the second positioning sub-parts are connected to each other to restrict the conductive connector from rotating relative to the metal part 21.

[0118] It is understandable that, based on the precise positioning described above, this example further constrains the attitude of the conductive connector 40 relative to the metal part 21. That is, in the assembled state, multiple first positioning sub-parts and corresponding multiple second positioning sub-parts are simultaneously engaged, thereby restricting the rotational freedom of the conductive connector 40 relative to the metal part 21.

[0119] For example, the metal component 21, such as the iron core 212, is provided with two mutually spaced second positioning sub-parts, which are protrusions. The conductive connector 40 is provided with two through holes corresponding to the two protrusions. During assembly, the two protrusions are respectively inserted into the two through holes to prevent the conductive connector 40 from rotating around any one of the protrusions as the axis. This is beneficial to improve the speed and quality of subsequent processes such as welding and reduce the defect rate of incomplete welding and weld deviation caused by positional deviation during welding.

[0120] In some embodiments, the first positioning sub-part is one of a positioning block and a positioning hole, and the second positioning sub-part is the other of a positioning block and a positioning hole, with the positioning block passing through the positioning hole.

[0121] For example, the metal component 21, such as the iron core 212, may have an outwardly protruding positioning block formed on its side. Correspondingly, a positioning hole is formed on the conductive connector 40, and the size of the positioning hole and the size of the positioning block are clearance fit or transition fit to facilitate assembly. Conversely, the positioning block can also be provided on the conductive connector 40, and the positioning hole is formed on the metal component 21. The specific arrangement is not limited here.

[0122] In some embodiments, the conductive connector 40 is welded to one of the metal components 21. Specifically, before welding, the conductive connector 40 and the metal component 21 have been pre-positioned by the aforementioned positioning part and finally fixed using processes such as laser welding. Of course, in addition to laser welding, other welding methods such as resistance welding can also be used, and no limitation is made here.

[0123] In this embodiment, by welding the conductive connector 40 and the metal component 21, the microscopic gap between them can be eliminated. Compared with connection methods such as riveting, welding can provide lower contact resistance and higher conductivity. Low resistance also means that induced charge or current can be efficiently guided to the grounding terminal, thereby maximally suppressing parasitic coupling and secondary radiation effects and further improving the quality of high-frequency signal transmission.

[0124] It should be noted that in this embodiment, welding is preferred as the connection between the conductive connector 40 and the metal component 21. For example... Figure 12As shown, taking the metal component 21 as an example of the iron core 212, the iron core 212 has two pole faces spaced apart along the second direction. The armature 231 is located on one side of the pole face. In this example, the iron core 212 is configured to engage with both ends of the armature 231 along the first direction when the armature 231 rotates in a seesaw manner. The minimum distance between the two pole faces is denoted as the preset distance W. If a riveting process is used, the impact or extrusion force during the riveting process will act on the iron core 212. As a precision magnetic conductive component, the pole face area of ​​the iron core 212 is relatively fragile. The riveting stress can easily cause the iron core 212 to undergo slight plastic deformation, reducing the preset distance W between the two pole faces to a smaller size W1, that is, W1 <W。

[0125] As the preset spacing decreases, the rotatable angle of the armature 231 around its axis decreases accordingly, causing the pole face to tilt. This is transmitted through the compression spring 232 to the moving spring assembly 31, resulting in a corresponding decrease in the linear travel of the moving spring. This means that the overtravel after contact between the moving and stationary contacts becomes smaller, leading to a decrease in contact pressure. Insufficient contact pressure reduces the actual contact area between the moving and stationary contacts, resulting in a significant increase in contact resistance, and even preventing closure. For high-frequency signals, increased contact resistance is detrimental to the stability of the distributed resistance and inductance of the contact part (high-frequency transmission part), leading to decreased transmission efficiency and increased signal distortion. Furthermore, increased contact resistance also leads to increased heating and arcing during contact switching, accelerating contact erosion and significantly shortening the electrical life of the high-frequency relay.

[0126] In addition, the reduced spacing between the pole faces of the iron core 212 will compress the enameled wire in this area, causing the insulating varnish layer on the surface of the enameled wire to crack or wear, which in turn leads to a short circuit between coil turns. This will further reduce the effective number of turns of the coil and increase internal losses, thus increasing the power consumption of the high-frequency relay coil and significantly increasing the internal heat generation during operation. The increased internal temperature rise of the high-frequency relay will directly lead to an increase in the resistivity of the metal parts 21 of the contact area, thereby further increasing the distributed resistance of the contact area, which is detrimental to the stability of high-frequency signal transmission.

[0127] In one example, the conductive connector 40 is welded to the shield 50; the end of the conductive connector 40 away from the metal component 21 has a connecting plane, which is configured to contact the surface of the shield 50. Specifically, the welding of the conductive connector 40 and the shield 50 can also be done by laser welding. As mentioned above, the end of the conductive connector 40 is constructed to be a connecting plane that can elastically abut against the surface of the shield 50. When the connecting plane is in close contact (surface contact) with the shield 50, the laser welding head focuses the laser beam on the junction edge of the two or on a predetermined welding area to perform spot welding or seam welding, so as to form a metallurgical bond between the two. This not only ensures the reliability of conductivity but also improves the connection strength between the two and enhances the ability of the conductive connector 40 to resist extreme impacts, vibrations, etc.

[0128] Furthermore, in this embodiment, the conductive connector 40 is grounded via the grounding lead of the shield 50, eliminating the need for an additional grounding lead and avoiding any impact from an additional grounding lead on the already designed load lead impedance. Additionally, the fewer leads help ensure the flatness of the high-frequency relay leads, preventing poor contact between some grounding leads or high-frequency signal leads and the PCB board pads due to poor flatness, thus avoiding reduced high-frequency signal transmission performance of the high-frequency relay.

[0129] In some embodiments, such as Figure 15 As shown, one end of the conductive connector 40 is provided with a first notch 401, which is configured as a first welding position for welding with the metal component 21.

[0130] In one example, such as Figure 15 As shown, the other end of the conductive connector 40 is provided with a second notch 402, which is configured as a second welding position for welding with the shield 50.

[0131] It is understood that the conductive connector 40 has a connection surface at both ends for fitting with the metal component 21 and the shield 50, respectively. At the edge of the connection surface, a first notch 401 and a second notch 402 can be formed by stamping or other means. The shape of the notch can be semi-circular, rectangular, V-shaped, etc., and there is no limitation here.

[0132] Once the conductive connector 40 is pre-positioned between the metal component 21 and the shielding cover 50, the edge of the first notch 401 fits tightly against the corresponding surface of the metal component 21, forming a clear welding area. In subsequent laser welding processes, the laser beam can precisely weld along the edge contour of the first notch 401. Similarly, the second notch 402 is configured in the same way as the first notch 401, and will not be described again here.

[0133] In this embodiment, the design of the first notch 401 and the second notch 402 can form easily identifiable markings on the edge of the conductive connector 40. That is, the notch can serve only as a marker for machine identification during laser welding, assisting the machine in quickly and accurately locating the precise position to be welded. In addition, welding is performed along the contour of the notch, and the contour line of the notch is longer than that of a straight line segment. This increases the effective connection length of the weld, improves the connection strength of the welded joint, and thus ensures the reliability of the grounding path.

[0134] In some embodiments, such as Figure 4 As shown, one of the multiple metal components 21 is an iron core 212, and the conductive connector is electrically connected to the iron core 212. Specifically, since the position of the iron core 212 is relatively fixed among the multiple metal components 21 in the electromagnetic part 20, the iron core 212 is selected as the object to be directly electrically connected by the conductive connector 40 in this example. As described in the above embodiment, one end of the conductive connector 40 can be directly fixed and electrically connected to the iron core 212 by pre-positioning, welding, or other methods.

[0135] In one example, the metal component 21 is constructed as a magnetically conductive component. Specifically, the magnetically conductive component can be a component supported by a soft magnetic material with high permeability, such as pure iron, iron-nickel alloy, or silicon steel sheet, to have the ability to guide and collect magnetic flux, so as to form a high-efficiency electromagnetic drive magnetic circuit. As described in the above embodiments, the iron core 212 and the armature 231 are the core components of the high-frequency relay magnetic circuit, and need to be manufactured using materials with good magnetic permeability to reduce the magnetic reluctance of the magnetic circuit and improve the magnetic flux conduction efficiency; when the coil is energized, it forms a sufficient electromagnetic attraction to reliably drive the armature to move.

[0136] In some embodiments, the conductive connector 40 is made of at least one of copper, silver, aluminum, titanium, copper alloy, and stainless steel, and is configured as a non-magnetic component. Specifically, although the conductive connector 40 is connected to the magnetically conductive iron core 212, it is itself made of a conductive and non-magnetic material to avoid bypassing or shunting the original magnetic circuit, which could lead to magnetic flux leakage, reduced attraction, or instability.

[0137] In some embodiments, the shield 50 is made of metal. Specifically, the conductive connector 40 is also made of metal. Both have good thermal conductivity, which helps the conductive connector 40 conduct heat from the electromagnetic part 20 to the shield 50, and then quickly conduct it to the outside of the high-frequency relay through the grounding terminal of the shield 50. This reduces the temperature rise of the coil of the electromagnetic part, which is beneficial to the normal or efficient operation of the coil current and electromagnetic attraction, improves the reliability of operation and contact contact, and thus helps to reduce the contact resistance. At the same time, this arrangement helps to stabilize the distributed resistance and distributed inductance of the contact part 30 (high-frequency transmission part), thereby ensuring the stability of high-frequency signal transmission and reducing insertion loss.

[0138] In some embodiments, such as Figure 4 As shown, the iron core 212 has two opposite ends along the second direction, and the conductive connector 40 is connected to the end face of at least one end of the iron core 212; the second direction is perpendicular to the first direction.

[0139] It is understandable that if the first direction is defined as the vertical direction, then the second direction is the horizontal direction perpendicular to the first direction, such as the left and right direction in the figure. The two opposite ends of the iron core 212 along the second direction are respectively two arms corresponding to the aforementioned U-shape or U-shaped structure. The two arms along the free ends of the first direction respectively form pole surfaces for attracting the armature 231.

[0140] For example, the end face of the iron core 212 connected to the conductive connector 40 is the surface of the two arms of the iron core 212 that are opposite to each other along the second direction, that is, the back surface of the pole face of the iron core 212 or its adjacent area. In practice, the conductive connector 40 is connected to the end face of the arm of the iron core 212 that extends along the first direction.

[0141] Specifically, the two end faces of the iron core 212 that are furthest apart along the second direction are provided with the aforementioned second positioning part 211. The conductive connector 40 is attached to the end face and is pre-positioned by the positioning part, and then fixed and electrically connected by welding or other means.

[0142] In this embodiment, by connecting the conductive connector 40 to the end face of the iron core 212, the conductive connector 40 can be arranged on the outer side of the electromagnetic part 20 and the contact part 30 along the second direction, without affecting the movement of the armature 231, the moving spring assembly 31, etc.

[0143] In some embodiments, such as Figure 4As shown, the electromagnetic part 20 includes a coil support 22 and an armature assembly 23; an iron core 212 is disposed on the coil support 22, and the end face of the iron core 212 connected to the conductive connector 40 is exposed on the coil support 22; the armature assembly 23 is located on one side of the coil support 22 along the first direction and is disposed close to the moving spring assembly 31; the armature assembly 23 is configured to rotate relative to the iron core 212 so that one end of the armature assembly 23 contacts the iron core 212 and the other end is separated from the iron core 212.

[0144] Specifically, the coil support 22, as mentioned in the above embodiment, is used to wind the coil and has an internal cavity extending along the second direction. The iron core 212 passes through this cavity, and at least a portion of the end faces of the iron core 212 are exposed outside the coil support 22. Exemplarily, the two end surfaces of the coil support 22 along the second direction are constructed with clearance notches, which allow at least a portion of the two end faces of the iron core 212 that are furthest apart along the second direction to be exposed. Of course, the exposed at least a portion of the end faces of the iron core 212 is used to mount the conductive connector 40.

[0145] The iron core 212 and the coil support 22 can be integrally injection molded. During the injection molding process, the end face of the iron core 212 can be reserved to form a structure in which at least part of the end face of the iron core 212 is exposed outside the coil support 22.

[0146] like Figure 10 and Figure 13 As shown, the armature assembly 23 includes an armature 231 and a compression spring 232 fixed to the armature 231. The compression spring 232 is located on the side of the armature 231 facing away from the coil support 22. The armature 231 has a protrusion 234, and the compression spring 232 has a corresponding through hole to achieve positioning connection between the two. The two can also be further fixedly connected by adhesive, welding, or other methods. Of course, a magnet 233 is also provided on the side of the armature 231 facing the coil support 22. The specific structure of the armature assembly 23 can be understood by referring to relevant technologies, and will not be described in detail here. In this example, the armature assembly 23 is configured to rotate in a seesaw manner relative to the iron core 212. During the rotation, one end of the armature assembly 23 along the second direction contacts (attracts) one pole face of the iron core 212, while the other end along the second direction separates from the other pole face of the iron core 212, thereby driving the compression spring 232 to move. This drives the moving spring assembly 31 corresponding to one end of the armature assembly 23 to complete the contact disconnection, and the moving spring assembly 31 corresponding to the other end to complete the contact closing, thus completing the contact switching.

[0147] In this embodiment, the end face of the iron core 212 along the second direction X is exposed to the coil bracket 22, which is beneficial to be able to operate directly on the end face of the iron core 212 without being blocked by the coil bracket 22 when assembling the conductive connector 40.

[0148] In some embodiments, such as Figure 3 and Figure 7 As shown, the iron core 212 has conductive connectors 40 connected to both ends of opposite sides along the second direction; the armature assembly 23 and the moving spring assembly 31 are located in the area between the two conductive connectors 40.

[0149] Specifically, in this example, there are two conductive connectors 40, which are respectively disposed on the two opposite end faces of the iron core 212 along the second direction. The two conductive connectors 40 can have the same structure or be arranged in a mirror-symmetrical manner. One end of each conductive connector 40 is connected to the end face of the iron core 212, and the other end extends to and is electrically connected to the corresponding shield 50.

[0150] Therefore, the armature assembly 23 and the moving spring assembly 31 are spatially positioned in the middle region between the two conductive connectors 40. In other words, the two conductive connectors 40 form a symmetrical rigid connection at both ends of the high-frequency relay along the second direction, which greatly improves the torsional stiffness and bending stiffness of the overall structure of the high-frequency relay. For example, when subjected to external impact or vibration, this symmetrical reinforcement structure can effectively suppress the swaying or micro-displacement of the electromagnetic part 20 relative to the base part 60, thereby preventing contact pressure changes or operational failures caused by structural deformation. In other words, if the electromagnetic part 20 sways or micro-displaces relative to the base part 60, it will disrupt the originally set attraction force matching, resulting in unreliable contact, and consequently, excessively high contact resistance, increasing the distributed resistance and distributed inductance of the contact part 30 (high-frequency transmission part), which is detrimental to the stability and efficiency of high-frequency signal transmission and increases insertion loss.

[0151] In some embodiments, such as Figure 5 and Figure 8 As shown, the shielding cover 50 has an extension piece 51 at its end, and the conductive connector 40 is connected to the extension piece 51 along a first direction. Specifically, the shielding cover 50 has one or more outwardly extending extension pieces 51 formed at one or both edges along a second direction. Each extension piece 51 has a bearing surface along the first direction, which is used to fit and abut against the end of the conductive connector 40. By improving the reliability of the grounding path, the integrity and transmission efficiency of high-frequency signals are ensured.

[0152] The extension piece 51 in this embodiment provides a clear position for the alignment, fitting, and fixing of the conductive connector 40, which helps to improve assembly accuracy and efficiency. Furthermore, while serving as an alignment structure, the extension piece 51 also plays a supplementary shielding role, covering the electromagnetic leakage gaps caused by the original gaps, further improving the shielding effectiveness of the high-frequency relay and reducing signal crosstalk.

[0153] In some embodiments, such as Figure 15As shown, the conductive connector 40 has a first mating portion 42, a clearance portion 43, a retraction portion 44, and a second mating portion 45 connected in sequence; wherein, the first mating portion 42 is connected to the metal component 21, and the second mating portion 45 is connected to the extension piece 51; the clearance portion 43 bends away from the connection with the first mating portion 42 in a direction away from the armature assembly 23 to form a clearance space; the retraction portion 44 bends towards the armature assembly 23 from the connection with the clearance portion 43.

[0154] It is understood that the conductive connector 40 has a first mating portion 42, a clearance portion 43, a retraction portion 44, and a second mating portion 45 sequentially along its extension path, and these portions can be integrally formed by continuously stamping and bending the same metal sheet. The first mating portion 42 is used to connect with the metal component 21 (e.g., the end face of the iron core 212), and may be provided with a first positioning portion 41 (e.g., a positioning hole) and a first welding position (e.g., a first notch 401). The second mating portion 45 is used to connect with the shielding cover 50 (or its extension piece 51), and may be provided with a second welding position (e.g., a second notch 402), and forms a connecting plane that elastically abuts against the shielding cover 50.

[0155] The clearance portion 43 is connected between the first docking portion 42 and the retracting portion 44. The clearance portion 43 extends from the connection with the first docking portion 42 in a direction away from the armature assembly 23, for example, extending outward in the second direction, thereby forming a clearance space around the movement trajectory of the armature assembly 23, ensuring that the armature 231 will not touch the conductive connector 40 during rotation.

[0156] The retractable portion 44 is connected between the relief portion 43 and the second docking portion 45. The retractable portion 44 extends from the connection with the relief portion 43 in a bent direction toward the armature assembly 23, for example, extending inward in a second direction, guiding the end of the conductive connector 40 (the second docking portion 45) to the target position for connection with the shield 50.

[0157] In this embodiment, the conductive connector 40 undergoes two bends, one outward and one inward. Specifically, the allowance portion 43 expands outward, while the retraction portion 44 contracts inward. This arrangement cleverly avoids the movement range of the armature assembly 23 while preventing excessive outward expansion from affecting the overall size of the high-frequency relay. Furthermore, the tortuous structure formed by the multiple bends of the conductive connector 40 inherently possesses good elasticity and deformation absorption capabilities. When the high-frequency relay is subjected to external impacts or internal thermal expansion and contraction stress, these bends can absorb stress and displacement through minute elastic deformation, thereby protecting the welding points of the first mating portion 42 and the second mating portion 45 and preventing them from cracking and failing due to stress concentration, thus improving the reliability of the long-term connection.

[0158] In some embodiments, such as Figure 15 and Figure 16 As shown, the clearance portion 43 includes a first sub-portion 431 and a second sub-portion 432 connected to each other. The end of the first sub-portion 431 opposite to the second sub-portion 432 is connected to the end of the first docking portion 42, and the end of the second sub-portion 432 opposite to the first sub-portion 431 is connected to the retraction portion 44. The extension direction of the second sub-portion 432 is consistent with the first direction. The extension direction of the first sub-portion 431 is between the first direction and the second direction. The first sub-portion 431 is configured to restrict the translation of the armature assembly 23 along the second direction.

[0159] Understandably, the extension direction of the second sub-part 432 is set to be consistent with the first direction, for example, extending vertically, serving as the outermost boundary of the conductive connector 40 to avoid the armature assembly 23. The extension direction of the first sub-part 431 is between the first direction and the second direction; that is, the first sub-part 431 is a diagonally extending folded edge, and this diagonally extending first sub-part 431 is located outside the end of the armature assembly 23 along the second direction.

[0160] When the high-frequency relay is subjected to an impact in the second direction, the armature assembly 23 may undergo excessive translation in the second direction due to inertia. At this time, the obliquely extending first sub-part 431 acts as a stop structure, abutting against the end of the armature assembly 23, thereby limiting further translation of the armature assembly 23 in the second direction.

[0161] In some embodiments, such as Figure 5 , Figure 9 and Figure 14 As shown, the high-frequency relay also includes a base portion 60, which has a receiving cavity and is located on one side of the armature assembly 23 along a first direction; at least a portion of the stationary spring 32 and at least a portion of the shield 50 are disposed in the receiving cavity; a portion of the moving spring assembly 31 passes through the base portion 60 and is partially located in the receiving cavity; the lead-out end of the stationary spring 32 extends out of the base portion 60 for connection to an external load; a portion of the shield 50 extends out of the base portion 60 for grounding; the base portion 60 is configured with a notch 601, and at least a portion of the shield 50 is exposed in the notch 601.

[0162] Understandably, the base portion 60 is used to support components such as the stationary spring 32 and the shielding cover 50. It can be formed integrally or assembled from an upper base 61 and a lower base 62, with the upper base 61 and lower base 62 forming a receiving cavity. The stationary spring 32, especially the portion with the stationary contact, is located within this receiving cavity. The driving member of the moving spring assembly 31 passes through the upper base 61, and the moving spring plate connected to the driving member is located within the receiving cavity. Figure 5As shown, the stationary spring 32 serves as a fixed end, remaining stationary relative to the base portion 60. One end of the stationary spring 32 is located within the receiving cavity of the base portion 60, forming a stationary contact. The other end is located outside the base portion 60, used for connection to an external load. In this example, there are three stationary springs 32: the normally open (NO) and normally closed (NC) ends located at both ends of the base portion 60 along the second direction X, respectively, and the middle one is the common (COM) end. The shield 50 is mostly located between the upper base 61 and the lower base 62, with multiple legs extending outside the base portion 60 for use as grounding terminals. The moving spring assembly 31 is movably inserted into the upper base 61 and can reciprocate along the first direction Y, thereby allowing the moving spring plate on it to contact and communicate with the stationary spring plate.

[0163] In this embodiment, the notch 601 forms an open opening on the upper surface of the base portion 60, thereby providing an access channel for the second mating portion 45 of the conductive connector 40. The conductive connector 40 can pass through the notch 601 from the outside of the base portion 60 and directly abut against the internal shield 50 or extension piece 51 to complete the connection. This arrangement can avoid the conductive connector 40 from going around the base portion 60, which helps to simplify the shape and assembly path of the conductive connector 40 and makes the connection operation more convenient.

[0164] Furthermore, the notch 601 allows the laser beam to pass through it and irradiate the connection area during welding, which helps reduce welding difficulty. It also facilitates inspection of the weld quality through the notch 601.

[0165] In some embodiments, such as Figure 17 As shown, a notch 601 is provided on at least one side of the base portion 60 along the second direction; the second mating portion 45 passes through the notch 601 and abuts against the shield 50.

[0166] Specifically, the notch 601 is located at the end of the upper base 61 of the base portion 60, so as to correspond to the position of the conductive connector 40 connected to the end face of the iron core 212. After the conductive connector 40 has completed its clearance and retraction bend, its end (second mating portion 45) points exactly to the position of the notch 601. During assembly, the second mating portion 45 passes through the notch 601 and abuts against the outer surface of the shield 50 (or its extension 51) to form an electrical connection.

[0167] The notch 601 in this embodiment is not only for exposing the shielding cover 50, but also allows the edge of the notch 601 to guide the second docking part 45 into place and restrict its swaying in the horizontal direction perpendicular to the entry direction after it is in place, thereby further enhancing the positional stability of the conductive connector 40 after assembly, thus ensuring the integrity and transmission efficiency of the high-frequency signal.

[0168] In some embodiments, such as Figure 16 As shown, the conductive connector 40 has an assembled state and an unassembled state. In the assembled state, the second mating portion 45 extends along the second direction and extends from the retracted portion 44 in a direction away from the upper base 61. In the unassembled state, the extension direction of the retracted portion 44 is consistent with the first direction, and the angle between the extension direction of the second mating portion 45 and the extension direction of the retracted portion 44 is greater than 90°.

[0169] It is understood that in this example, the non-assembled state refers to the free state of the conductive connector 40 before it is assembled with other components; the assembled state refers to the final state after the conductive connector 40 is installed inside the high-frequency relay and is properly engaged with the shield 50 (or its extension 51).

[0170] In the unassembled state, the extension direction of the retractable portion 44 is consistent with the first direction, and the second mating portion 45 extends further from the end of the retractable portion 44, with the extension direction of the second mating portion 45 forming an angle greater than 90° with the extension direction of the retractable portion 44. In other words, the second mating portion 45 is tilted outward relative to the retractable portion 44, rather than being collinear with the retractable portion 44 or forming an acute angle.

[0171] In the assembled state, the first mating part 42 is fixedly connected to the metal component 21 (such as the end face of the iron core 212), while the second mating part 45 needs to be mated with the extension piece 51 of the shielding cover 50. In this embodiment, the extension piece 51 of the shielding cover 50 has a contact surface on its upper side along the first direction, and the second mating part 45 is configured to fit against the contact surface of the extension piece 51, increasing the conductive area and thus ensuring the integrity and transmission efficiency of the high-frequency signal.

[0172] During assembly, the second mating portion 45 is pushed into the notch 601 of the base portion 60 along the second direction until it contacts the extension piece 51. Since the second mating portion 45 is open outwards (angle greater than 90°) in the unassembled state, when the extension piece 51 forces the second mating portion 45 to close relative to the retracted portion 44, the second mating portion 45 undergoes elastic deformation, reducing the angle between it and the retracted portion 44 to approximately 90° or a preset mating angle. Finally, in the assembled state, the second mating portion 45 extends along the second direction and extends from the retracted portion 44 in a direction away from the base portion 60, for example, bending outwards from the end of the retracted portion 44. At this time, a tight elastic contact is formed between the second mating portion 45 and the extension piece 51.

[0173] In this embodiment, by designing the included angle between the second docking part 45 and the retracting part 44, the second docking part 45 is forced to undergo elastic deformation during assembly to accumulate elastic restoring force. This elastic restoring force will continue to act between the shielding cover 50 and the metal part 21 to ensure a stable connection between the three and effectively prevent poor contact, thereby ensuring the reliability of the grounding path and thus ensuring the integrity and transmission efficiency of the high-frequency signal.

[0174] In addition, in this embodiment, the second docking part 45 is designed to extend outward. When assembled with the shielding cover 50, the second docking part 45 can serve as a guide slope to facilitate smooth pushing into the notch 601 and fitting with the shielding cover 50.

[0175] In some embodiments, such as Figure 16 and Figure 17 As shown, the conductive connector 40 has an assembled state and an unassembled state. In the unassembled state, the conductive connector 40 has a first dimension along a first direction. In the assembled state, the conductive connector 40 has a second dimension along the first direction. The first dimension is larger than the second dimension.

[0176] Specifically, in the unassembled state, that is, in the free state where the conductive connector 40 is not constrained by external forces, it has a first dimension h1 along the first direction. In the assembled state, that is, after the conductive connector 40 is installed inside the high-frequency relay and connected to the metal part 21 of the electromagnetic part 20 and the shield 50 of the contact part 30, it has a second dimension h2 along the first direction, and h1 is greater than h2.

[0177] Therefore, the conductive connector 40 in this embodiment has a compressible dimension along the first direction. For example, the conductive connector 40 can be designed as an elastic element, which facilitates deformation assembly and, through deformation during force storage, achieves a pre-tightened connection between the metal component 21 and the shielding cover 50. The specific structure of the conductive connector 40 can be understood by referring to the above embodiment, and will not be repeated here.

[0178] In some examples, such as Figure 1 and Figure 2 As shown, the high-frequency relay also includes a housing 10, which has a receiving cavity and an opening, and a base portion 60 is connected to the opening of the housing 10. The electromagnetic portion 20 and the contact portion 30 are both located within the housing 10. At least a portion of the stationary spring extends out of the housing 10 to connect to an external load; and at least a portion of the shield 50 also extends out of the housing 10 for grounding.

[0179] 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.

[0180] 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.
