Description

Technical Field

[0001] This invention relates to the field of relays, and more specifically to a radio frequency relay with a bifurcated structure. Background Technology

[0002] Radio frequency (RF) relays typically come in single-pole double-throw (SPD), double-pole double-throw (DPD), and single-pole multi-throw (SPMD) types. In the contact system design of SPDMD RF relays, the information transmission channel of the cavity generally adopts a rectangular coaxial transmission structure. Due to the transmission of higher frequencies (e.g., above 20 GHz), the size of the center contact of the main stationary contact is limited. This restricts the number of relay branches. When the number of branches is excessive, such as more than 15, directly connecting all branch stationary contacts to the center stationary contact via moving contacts results in an overly dense contact count, negatively impacting RF transmission performance. Generally, when the number of branch contacts exceeds 10, it becomes difficult to achieve good matching for RF channels above 20 GHz. Therefore, the number of branches in existing relays is generally limited to 10 or less; otherwise, RF parameters will drop sharply. Thus, there is a need for an RF relay that can double the number of branches without reducing the relay's insertion loss and voltage standing wave ratio (VSWR). Summary of the Invention

[0003] To address the shortcomings of existing technologies, this invention provides a novel radio frequency relay with a branched structure, which solves the problem of a limited number of branches in existing technologies without reducing the relay's operating frequency.

[0004] To achieve the above objectives, the present invention employs the following technical solution:

[0005] A radio frequency relay with a bifurcated structure includes a radio frequency cavity. A stationary contact mechanism is provided within the radio frequency cavity. Above the stationary contact mechanism are a moving contact mechanism and a power mechanism. The power mechanism is connected to the moving contact mechanism to drive the moving contact mechanism towards or away from the stationary contact mechanism. The stationary contact mechanism includes a main stationary contact member, with multiple secondary stationary contacts arranged around its periphery. The moving contact mechanism includes an active contact member located above the main stationary contact member. The active contact member extends outward from its own center to form multiple contact arms. The end of each contact arm away from the active contact member extends outward to form two secondary contact members, namely a first secondary contact member and a second secondary contact member. Each secondary contact member corresponds one-to-one with each secondary stationary contact member to expand the number of relay channels. Each secondary contact member is connected to its corresponding secondary stationary contact member to conduct the corresponding radio frequency channel.

[0006] Furthermore, multiple support platforms are provided inside the radio frequency cavity, each support platform corresponding to each contact arm. When the power mechanism drives the contact arm to move downward so that the corresponding driven contact and its corresponding stationary contact can make contact and connect, the support platform supports the corresponding contact arm to facilitate stable contact between the driven contact and the stationary contact.

[0007] Furthermore, a first reinforcing rib is provided on the contact arm along its own length direction, and a second reinforcing rib is provided on the driven contact member along its own length direction. The first reinforcing rib and the second reinforcing rib are connected to avoid bridging when the driven contact member and the stationary contact member come into contact.

[0008] Furthermore, the active contact member has an active contact point on the side near the main stationary contact member; the first driven contact member and the second driven contact member both have driven contacts on the side near the driven stationary contact member; the power mechanism drives the contact arm to move downward so that the active contact point and the driven contact point can contact and connect with the main stationary contact member and the corresponding driven stationary contact member.

[0009] Furthermore, a main stationary contact is provided on the upper side of the main stationary contact corresponding to the position of the active contact; a secondary stationary contact is provided on the upper side of the secondary stationary contact corresponding to the position of the secondary contact; the contact arm is moved downward by the power mechanism so that the active contact and the secondary contact are in contact with the main stationary contact and the corresponding secondary stationary contact to conduct the corresponding radio frequency channel.

[0010] Furthermore, the contact arm and the first and second driven contacts extending therefrom form a Y-shaped structure. There is a first distance between the active contact of the active contact and the extension of the contact arm, and a second distance between the driven contacts of the first and second driven contacts. The first distance is greater than the second distance, so that each of the driven stationary contacts is dispersed around the main stationary contact.

[0011] Furthermore, the power mechanism includes multiple pushing components, and a guide groove adapted to the pushing components is provided on the radio frequency cavity. The pushing components pass through the guide groove and are connected to the corresponding contact arms to drive the active and driven contact members to move up and down along the guide groove.

[0012] Furthermore, the pushing assembly includes a main push rod and a secondary push rod. The lower part of the main push rod is connected to the active contact. There are two secondary push rods, which are respectively connected to the first driven contact and the second driven contact. By pushing different secondary push rods, different radio frequency channels can be turned on.

[0013] Furthermore, multiple main connection positions are provided around the active contact member, and the main connection positions are connected to the lower part of the main push rod; the first driven contact member is provided with a first connection position, and the lower part of one of the auxiliary push rods is connected to the first connection position; the second driven contact member is provided with a second connection position, and the lower part of another auxiliary push rod is connected to the second connection position.

[0014] Furthermore, the number of relay channels is obtained by multiplying the number of contact arms by the number of driven contacts in each contact arm.

[0015] Compared with the prior art, the beneficial effect of the present invention is that, by adopting the above solution, the passive contact is set by extending the contact arm on the outside of the active contact, and the passive contact is dispersed around the active contact by adopting a multi-level branched design, which can achieve good matching of radio frequency transmission, and can double the number of radio frequency relays without reducing the insertion loss and voltage standing wave ratio of the relay, thus having great market application value.

[0022] To facilitate understanding of the present invention by those skilled in the art, specific embodiments of the present invention are described below with reference to the accompanying drawings. Preferred embodiments of the present invention are shown in the drawings. However, the present invention can be implemented in many different forms and is not limited to the embodiments described in this specification. Rather, these embodiments are provided to provide a thorough and complete understanding of the disclosure of the present invention.

[0023] It should be noted that when a component is referred to as being "fixed to" another component, it can be directly attached to the other component or there may be an intervening component. When a component is referred to as being "connected to" another component, it can be directly connected to the other component or there may be an intervening component. The terms "mounted," "fixed," "top," "connected," and similar expressions used in this specification are for illustrative purposes only.

[0024] Unless otherwise defined, all technical and scientific terms used in this specification have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains. The terminology used in this specification is for the purpose of describing particular embodiments only and is not intended to limit the invention.

[0025] One embodiment of the present invention is as follows: Figure 1 , 3As shown, this RF relay with a bifurcated structure is applied to single-pole multi-throw RF relays, specifically concerning the contact structure. Based on a rectangular coaxial transmission structure, a multi-stage bifurcated design is used for the RF branching, achieving good matching of RF transmission and doubling the number of RF relay branching points without reducing the relay's insertion loss and voltage standing wave ratio. Specifically, it includes an RF cavity, within which a static contact mechanism 2 is provided. Above the static contact mechanism 2, a moving contact mechanism 1 and a power mechanism 4 are provided. The power mechanism 4 is connected to the moving contact mechanism 1 to drive the moving contact mechanism 1 towards or away from the static contact mechanism 2. The static contact mechanism 2 includes a main static contact 2-1, with multiple secondary static contacts 2-2 arranged around its periphery. The moving contact mechanism 1 includes an active contact 1-1 located on the main static contact... Above component 2-1, the active contact component 1-1 extends outward from itself to form multiple contact arms 1-4. The end of each contact arm 1-4 away from the active contact component 1-1 extends outward to form two driven contacts, namely the first driven contact 1-2 and the second driven contact 1-3. Each driven contact corresponds to each of the driven stationary contacts 2-2 to expand the number of relay channels. Each driven contact is connected to its corresponding driven stationary contact 2-2 to conduct the corresponding radio frequency channel. By contacting the active contact 1-1 with the main stationary contact 2-1 and selecting different driven contact movements, different bypasses can be connected to the main stationary contact 2-1, thereby achieving relay channel selection.

[0026] Specifically, the RF relay with a bifurcated structure in this embodiment is suitable for single-pole multi-throw RF relays. The active contact 1-1 is provided with N contact arms 1-4, and each contact arm 1-4 is provided with two driven contacts. The number of driven contacts is 2N, that is, the number of branches of the relay is 2N. This structure can be used in the contact system design of single-pole multi-throw RF relays. Based on the rectangular coaxial transmission structure, a multi-level bifurcated design is used for the RF branching, which can achieve good matching of RF transmission and double the number of RF relay branches without reducing the insertion loss and voltage standing wave ratio of the relay.

[0027] Furthermore, each contact arm 1-4 is equipped with four driven contacts, and the number of driven contacts is 4N, which means the number of relay branches is 4N, in order to further expand the relay and meet more needs, and to meet the complex requirements of the switch matrix.

[0028] Specifically, such as Figure 1As shown, the radio frequency cavity includes a cavity 5 and a cavity cover 6 adapted thereto. The main static contact 2-1 is installed in the middle of the cavity 5, and multiple secondary static contacts 2-2 surround the periphery of the main static contact 2-1. The cavity cover 6 is provided with a guide groove adapted to the power mechanism 4. The bottom end of the power mechanism 4 passes through the guide groove and is connected to the contact arm 1-4 of the moving contact mechanism 1. The main static contact 2-1 and secondary static contact 2-2 of the static contact mechanism 2 have a vertical movement gap with the active contact 1-1 and the secondary contact of the power mechanism 4. When the active contact 1-1 and the secondary contact move up and down through the power mechanism 4, they are connected or disconnected from the main static contact 2-1 and the secondary static contact 2-2.

[0029] In this embodiment, as Figure 2 , 5 As shown, multiple support platforms 3 are provided in the radio frequency cavity, and each support platform 3 is provided corresponding to each contact arm 1-4. When the power mechanism 4 drives the contact arm 1-4 to move down so that the corresponding driven contact and its corresponding stationary contact 2-2 are in contact and connected, the support platform 3 supports the corresponding contact arm 1-4 so as to ensure stable contact between the driven contact and the stationary contact 2-2.

[0030] Specifically, the active contact 1-1 is provided with N contact arms 1-4, and N support platforms 3 are provided in the cavity 5. Each support platform 3 is provided corresponding to each contact arm 1-4 of the moving contact mechanism 1. When the power mechanism 4 drives the active contact 1-1 and the corresponding driven contact to move down and make contact with their corresponding static contact 2-2, the support platform 3 supports the corresponding contact arm 1-4 to ensure reliable contact between the contact point of the moving contact and the contact point of the static contact. This avoids excessive contact due to the moving contact mechanism 1 moving up and down, which could cause deformation of the contact arm 1-4, resulting in weak contact and reduced stability.

[0031] In this embodiment, as Figure 4 As shown, the contact arm 1-4 is provided with a first reinforcing rib 1-5 along its own length direction, and the driven contact is provided with a second reinforcing rib 1-6 along its own length direction. The first reinforcing rib 1-5 and the second reinforcing rib 1-6 are connected to avoid bridging when the driven contact and the stationary contact 2-2 come into contact.

[0032] Specifically, the width of the first reinforcing rib 1-5 is smaller than the width of the contact arm 1-4, and the width of the second reinforcing rib 1-6 is smaller than the width of the driven contact member. The first reinforcing rib 1-5 is arranged along the central axis of the contact arm 1-4, and the first reinforcing rib 1-5 and the second reinforcing rib 1-6 are integrally formed to strengthen the strength of the contact arm 1-4, so as to avoid excessive contact times when the moving contact mechanism 1 moves up and down, which would cause the contact arm 1-4 to deform, resulting in weak contact and reduced stability.

[0033] For example, the width of the contact arm 1-4 and the width of the driven contact are both 10mm, and the width of the first reinforcing rib 1-5 and the second reinforcing rib 1-6 are both 3mm. A ridge extends along the center line of the contact arm 1-4 to form the first reinforcing rib 1-5; a ridge extends along the center line of the driven contact to form the second reinforcing rib 1-6. The reinforcing ribs strengthen the contact arm 1-4, and a support platform 3 is provided below the contact arm 1-4. This structure avoids bridging during operation. The force pressed down by the power mechanism 4 is received by the contacts of the active contact 1-1 and the corresponding driven contact, which increases the pressure between the contacts, improves the reliability of the contact, and ensures the working reliability of the relay.

[0034] In this embodiment, as Figure 3 As shown, the active contact 1-1 is provided with an active contact on the side near the main stationary contact 2-1; the first driven contact 1-2 and the second driven contact 1-3 are both provided with driven contacts on the side near the driven stationary contact 2-2; the power mechanism 4 drives the contact arm 1-4 to move downward so that the active contact and the driven contact can contact and connect with the main stationary contact 2-1 and the corresponding driven stationary contact 2-2.

[0035] Specifically, an active contact is provided on the lower side of the active contact 1-1 corresponding to the position of the main stationary contact 2-1; a driven contact is provided on the lower side of the outer ends of the first driven contact 1-2 and the second driven contact 1-3; for example, if the moving contact mechanism 1 is provided with 10 contact arms 1-4, the radio frequency channel of the relay can be expanded to a structure of 10-20 channels. By selecting different driven contacts, the channel selection of the relay can be realized.

[0036] In this embodiment, as Figure 2 As shown, the upper side of the main stationary contact 2-1 corresponds to the position of the active contact 1-1 and is provided with a main stationary contact; the upper side of the secondary stationary contact 2-2 corresponds to the position of the secondary contact and is provided with a secondary stationary contact; the power mechanism 4 drives the contact arm 1-4 to move downward so that the active contact and the secondary contact can contact and connect with the main stationary contact and the corresponding secondary stationary contact to conduct the corresponding radio frequency channel.

[0037] Specifically, the main stationary contact is the center stationary contact, and the secondary stationary contacts provided on each of the secondary stationary contact members 2-2 are either bypass stationary contacts or branch stationary contacts; when it is necessary for the center stationary contact to connect with the bypass stationary contact, the active contact and the corresponding secondary contact move downwards simultaneously to connect with the center stationary contact and the corresponding bypass stationary contact.

[0038] For example, when the second channel of the relay needs to be connected, the power mechanism 4 drives the contact arm 1-4 of the corresponding second channel to move downward, so that the active contact and the driven contact of the second channel move downward at the same time, connecting with the center stationary contact and the corresponding bypass stationary contact. The same applies to the others, and they are supported by the corresponding support platform 3 to ensure reliable contact.

[0039] In this embodiment, as Figure 3 As shown, the contact arm 1-4 and the first driven contact 1-2 and the second driven contact 1-3 extending therefrom form a Y-shaped structure. There is a first distance between the active contact of the active contact 1-1 and the extension of the contact arm 1-4, and there is a second distance between the driven contact of the first driven contact 1-2 and the driven contact of the second driven contact 1-3. The first distance is greater than the second distance so that each of the driven stationary contacts is dispersed around the main stationary contact.

[0040] Specifically, there is a third gap between each pair of adjacent driven contacts, and the first gap is not less than the sum of the second gap and the third gap; for example, the distance between the second driven contact of the first contact arm and the first driven contact of the second contact arm is the third gap when the first contact arm and the second contact arm are adjacent; the first gap is the length of the contact arms 1-4; the second gap is the distance between the driven contacts of the two driven contacts extending from the same contact arm; through this Y-shaped structure design, the driven stationary contacts are dispersed around the main stationary contact to avoid the number of contacts being too dense.

[0041] If all bypass stationary contacts are directly connected to the central stationary contact via moving contacts, the number of contacts will be too dense, thus affecting RF transmission performance. Generally, when there are more than 10 bypass contacts, it is difficult to achieve good matching of RF channels above 20G. Therefore, in this embodiment, each driven contact is distributed from the side of the active contact to the periphery using a Y-shaped structure, thereby dispersing the driven stationary contacts around the main stationary contact to avoid an excessively dense number of contacts that would affect RF transmission performance.

[0042] In this embodiment, as Figure 2As shown, the power mechanism 4 includes multiple pushing components. A guide groove adapted to the pushing components is provided on the radio frequency cavity. The pushing components pass through the guide groove and are connected to the corresponding contact arms 1-4 to drive the active contact and driven contact to move up and down along the guide groove.

[0043] Specifically, the number of the pushing components is the same as the number of the contact arms 1-4. For example, the moving contact mechanism 1 is provided with 10 contact arms 1-4, that is, the power mechanism 4 includes 10 pushing components. Each pushing component is arranged in a one-to-one correspondence with each contact arm 1-4, so that the corresponding contact arm 1-4 is moved down by the pushing component and contacts the corresponding stationary contact 2-2 to conduct the corresponding radio frequency channel. By selecting different pushing components to work, different bypasses are connected to the main stationary contact 2-1, thereby realizing the channel selection of the relay.

[0044] In this embodiment, as Figure 2 As shown, the pushing assembly includes a main push rod 4-1 and a secondary push rod 4-2. The lower part of the main push rod 4-1 is connected to the active contact 1-1. There are two secondary push rods 4-2, which are respectively connected to the first driven contact 1-2 and the second driven contact 1-3. By pushing different secondary push rods 4-2, different radio frequency channels can be turned on.

[0045] Specifically, each of the aforementioned pushing components has three guide slots on the cavity cover 6 of the radio frequency cavity, namely a main guide slot, a first guide slot, and a second guide slot. The main push rod 4-1 passes through the main guide slot, the first auxiliary push rod passes through the first guide slot, and the second auxiliary push rod passes through the second guide slot. The upper parts of the main push rod 4-1, the first auxiliary push rod, and the second auxiliary push rod all extend out of the upper end face of the cavity cover 6 to facilitate the movement of the pushing component.

[0046] In this embodiment, as Figure 3 As shown, multiple main connection positions are provided around the active contact 1-1, and the main connection positions are connected to the lower part of the main push rod 4-1; the first driven contact 1-2 is provided with a first connection position, and the lower part of one of the auxiliary push rods 4-2 is connected to the first connection position; the second driven contact 1-3 is provided with a second connection position, and the lower part of another auxiliary push rod is connected to the second connection position.

[0047] Specifically, the main connection position is a positioning hole, and the lower part of the main push rod 4-1 is provided with a positioning ring that matches the positioning hole. The lower part of the main push rod 4-1 passes through the main guide groove, so that the positioning ring is engaged with the positioning hole of the active contact 1-1. The bottom end of the main push rod 4-1 is connected to the bottom of the cavity 5 of the radio frequency cavity through a telescopic spring, and the telescopic spring drives the main push rod 4-1 to reset.

[0048] Specifically, the first connection position and the second connection position have the same structure, which is a positioning slot. The two auxiliary push rods 4-2 pass through the first guide slot and the second guide slot respectively. The lower part of the auxiliary push rod 4-2 is provided with a positioning strip, so that the positioning strip engages with the positioning slot of the driven contact. The auxiliary push rod 4-2 moves down to drive the driven contact to move down, so that its driven contact contacts contact the corresponding stationary contact, so as to conduct the corresponding radio frequency channel.

[0049] In this embodiment, as Figure 3 As shown, the number of relay channels is obtained by multiplying the number of contact arms 1-4 by the number of driven contacts provided in each contact arm 1-4.

[0050] Specifically, the moving contact mechanism 1 includes N contact arms 1-4, each contact arm 1-4 is provided with A driven contacts, and the number of relay channels is (N×A). For example, the active contact 1-1 is provided with ten contact arms 1-4 around its perimeter, where eight contact arms 1-4 are each provided with two driven contacts, and two contact arms 1-4 are each provided with one driven contact. Then the number of relay channels is (8×2)+(2×1)=18, and the number of relay channels is 18, which can be used to further expand the relay to meet the complex requirements of the switch matrix.

[0051] In this specific implementation, the moving contact mechanism includes 10 contact arms. The first and sixth contact arms each have one driven contact, and the remaining 8 contact arms are each forked at their outer ends and have two driven contacts. That is, the relay contains 18 channels. For example, if the fourth channel of the relay needs to be connected, the fourth channel corresponds to the first driven contact of the third contact arm. The third contact arm is above the third push assembly. By moving the main push rod and the first auxiliary push rod of the third push assembly downwards simultaneously, the active contact and the driven contact of the first driven contact of the third contact arm move downwards simultaneously, connecting with the central stationary contact and the corresponding bypass stationary contact, and are supported by the corresponding support platform to ensure reliable contact.

[0052] It should be noted that the above-mentioned technical features can be combined with each other to form various embodiments not listed above, all of which are considered to be within the scope of this invention specification; and, for those skilled in the art, improvements or modifications can be made based on the above description, and all such improvements and modifications should fall within the protection scope of the appended claims.
