Description

Technical Field

[0001] The invention belongs to the field of connectors, and in particular relates to a multi-channel radio frequency integrated module, an integrated module unit and a switching module unit. Background Art

[0002] Multi-core integrated RF connectors are widely used in aerospace, communications, medical, rail transit, and industrial fields. With the advent of the big data era, all fields are pursuing miniaturized, integrated, and modularized equipment, and multi-channel RF modules are in urgent need of developing new forms.

[0003] Generally speaking, the existing multi-channel RF integrated module mainly includes two parts, a RF contact and an insulator base for integrating multiple RF contacts, such as Figure 1 and Figure 2 As shown. Whether it is a pin or a socket, the basic components of the RF contact include an inner conductor, an outer conductor surrounding the inner conductor, and an insulator between the inner conductor and the outer conductor (air can also be used as an insulating medium). The RF contact is used to transmit high-frequency signals. The insulator base is only used to integrate multiple RF contacts and does not participate in RF signal transmission.

[0004] Figure 1 , 2 The defects of the prior art shown are: (1) When two mating multi-channel RF integrated modules are plugged in, the first inner conductor and the second inner conductor, as well as the first outer conductor and the second outer conductor, are plugged in with round pins and round holes. The contact length is long, and repeated plugging and unplugging can easily cause significant wear on the inner and outer conductors, resulting in poor signal transmission.

[0005] (2) The insertion accuracy requirement is high. In order to facilitate the insertion and alignment, it is often necessary to add a multi-level guiding structure, which makes the overall structure more complicated.

[0006] (3) Each RF contact requires an independent insulator, so the overall structure is complex to assemble and has a low degree of integration. Summary of the invention

[0007] The purpose of the present invention is to provide a multi-channel RF integrated module, an integrated module unit and a switching module unit. The multi-channel RF integrated module adopts a three-piece structural design, optimizes the structure of the RF contact, and realizes reliable connection through the elastic contact of the elastic part, avoids the wear of repeated plugging and unplugging between the contacts, improves the structural durability, ensures the transmission quality, and greatly simplifies the system.

[0008] In order to achieve the above-mentioned purpose, the first technical solution adopted by the present invention is: a multi-channel RF integrated module, including two integrated module units and one adapter module unit, the integrated module unit includes an integrated module insulating base and a RF contact, the RF contact is arranged on the integrated module insulating base, the adapter module unit includes a adapter module insulating base and a adapter contact, the adapter contact is arranged on the adapter module insulating base, and the adapter contact heads at both ends of the adapter contact respectively extend from two opposite end surfaces on the adapter module insulating base, for one-to-one surface elastic contact with the RF contact end of the RF contact on the integrated module unit on the same side.

[0009] The beneficial effects are as follows: the present invention adopts a three-stage system, two integrated module units realize signal connection through the adapter module unit, and the RF contacts on the integrated module unit and the adapter contacts on the adapter module unit can be in one-to-one surface-mounted elastic contact, which can avoid the wear of repeated plugging and unplugging between the contacts while ensuring reliable contact, thereby improving the durability of the structure and ensuring the transmission quality; in addition, the surface-mounted elastic contact can also be effectively aligned to reduce the plug-in and pull-out force of the pins and sockets, thereby solving the problem of large plug-in and pull-out force of multi-channel RF modules.

[0011] The beneficial effect is that the RF inner conductor and the RF outer conductor in the RF contact piece are in elastic contact with the transfer contact head of the transfer contact piece through a spring sheet, so that the contact between the transfer contact head and the spring sheet in the radial direction has a certain contact tolerance rate. During the contact process, the transfer contact head can still maintain reliable contact between the two with a slight sliding on the spring sheet, that is, contact deviation within a certain range in the radial direction is allowed, thereby improving the fault tolerance rate of the conductor contact. Compared with the coaxial inter-insertion in the prior art, the insertion accuracy threshold is lowered, and there is no need to add an additional multi-stage guiding structure to ensure the insertion accuracy.

[0022] The beneficial effect is that the first elastic arm and the second elastic arm are both multi-section curved structures with the smooth curved portion in the middle serving as a contact head, which can avoid scratching the corresponding spring pieces, and the curved structure can provide sufficient elastic force to ensure reliable contact with the RF contact piece.

[0023] Furthermore, a convex point for achieving point contact is fixedly provided on the transition outer conductor contact head of the first elastic arm and / or the transition inner conductor contact head of the second elastic arm.

[0052] The present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments, but they are not intended to limit the invention in any way.

[0053] Example 1: Refer to the attached Figure 3 As shown, a multi-channel RF integrated module includes an integrated module unit 1 and a switching module unit 2. The integrated module unit 1 includes an integrated module insulating base 3 and a plurality of RF contacts 4, and the switching module unit 2 includes a switching module insulating base 5 and a switching contact 6. Two integrated module units 1 are provided, which are respectively located on both sides of the switching module unit 2, and the signal conduction of the two integrated module units 1 is realized through the switching module unit 2.

[0054] In the integrated module unit 1 , the multiple RF contacts 4 are arranged on the integrated module insulating base 3 according to a certain rule, and the contact ends of the RF contacts 4 are all exposed from the same side of the integrated module insulating base 3 for contacting the adapter module unit 2 . Figure 3 In the integrated module unit 1 shown, the arrangement rule of the RF contacts 4 is to set two rows of RF contacts 4 on the integrated module insulating base 3, and each row includes 7 RF contacts 4 arranged at intervals along the length direction of the integrated module insulating base 3. In other embodiments, the number and arrangement of the RF contacts 4 can be adjusted according to actual conditions to meet actual needs.

[0055] In the adapter module unit 2, multiple adapter contacts 6 are installed and arranged according to the arrangement rule of the RF contacts 4 in the integrated module unit 1, so that two ends of the adapter contacts 6 are exposed from opposite sides of the adapter module insulating base 5, and respectively contact with the corresponding RF contacts 4 on the two integrated module units 1.

[0056] Combine the following Figure 4 , 5 As shown, the structure of the RF contact 4 is described. The RF contact 4 includes an RF outer conductor 401 and an RF inner conductor 402. When the RF outer conductor 401 and the RF inner conductor 402 are mounted on the integrated module insulating base 3, they are separated by an insulating structure. The RF outer conductor 401 is a coaxial structure made of rolled metal sheets, and is divided into a terminal 401-1, a hollow cylinder 401-2 and a first semi-enclosed structure 401-3 in the axial direction of the RF outer conductor 401, wherein the hollow cylinder 401-2 is located in the middle of the RF outer conductor 401, and the terminal 401-1 and the first semi-enclosed structure 401-3 are distributed on both sides of the hollow cylinder 401-2 in the axial direction. The first semi-enclosed structure 401-3 is coaxially arranged with the hollow cylinder 401-2. The semi-enclosed structure 401-3 is a U-shaped structure. Two axially extending cantilevers are arranged on the edge of the first semi-enclosed structure 401-3 opposite to the hollow cylinder 401-2. The first spring piece 401-4 is arranged at the end of the cantilever. The first spring piece 401-4 is an integral structure with the corresponding cantilever and is perpendicular to it. Therefore, the first spring piece 401-4 can be formed by bending the end of the cantilever by 90°. The RF inner conductor 402 is a cylindrical structure, and a second spring piece 402-1 is arranged at one end thereof. The second spring piece 402-1 is perpendicular to the axis of the RF inner conductor 402. The RF inner conductor 402 is inserted into the RF outer conductor 401, and the first semi-enclosed structure 401-3 forms a semi-enclosure of the RF inner conductor 402. After the RF outer conductor and the RF inner conductor are installed on the integrated module insulating base 3, the two first spring sheets are respectively located on both sides of the second spring sheet, and the three spring sheets are exposed from the contact end surface of the integrated module insulating base 3, and are used for elastic contact with the corresponding transfer contact 6 on the transfer module unit 2.

[0057] Combine the following Figure 6-9As shown, the structure of the transition contact 6 is described. The transition contact 6 includes a transition outer conductor 601 and a transition inner conductor 602, which are mounted on the transition module insulation base 5 and separated by the insulation structure of the transition module insulation base 5. A second semi-enclosed structure 601-1 formed by bending a metal sheet is provided in the middle of the transition outer conductor 601. The second semi-enclosed structure 601-1 is a U-shaped structure, and two elastic arms formed by bending are provided at both ends of the axial direction thereof, as the first elastic arms 601-2. The two first elastic arms 601-2 located at the same end of the second semi-enclosed structure 601-1 are arranged in parallel and spaced apart. The middle part of the transition inner conductor 602 is a sheet structure, which is used as the middle connecting piece 602-1. A bent elastic arm is provided at each of the two ends of the axial direction of the middle connecting piece 602-1, as the second elastic arm 602-2. When the transition inner conductor 602 is assembled and used with the transition outer conductor 601, the middle connecting piece 602-1 of the transition inner conductor 602 is located at the U-shaped opening position of the second semi-enclosed structure 601-1, which can avoid signal leakage and ensure that the bending angle of the second elastic arm 602-2 of the transition inner conductor 602 is large enough, thereby ensuring that the second elastic arm 602-2 has sufficient elastic force and can recover its shape more quickly after elastic deformation.

[0058] Specifically, Fig. 9 As shown, the second semi-enclosed structure 601-1 on the transition outer conductor 601 includes a middle substrate 601-3 and middle side wing plates 601-4 located on opposite sides of the middle substrate 601-3. The middle substrate 601-3 and the middle side wing plates 601-4 on both sides are an integral structure, and the two middle side wing plates 601-4 are bent to form a U-shaped second semi-enclosed structure 601-1. The first elastic arm 601-2 is formed by bending a metal strip, one end of which is connected to the middle substrate 601-3 to form an integral structure, and the other end extends away from the middle substrate 601-3, and then bends twice toward the second semi-enclosed structure 601-1, so as to form a V-shaped structure at the end of the first elastic arm 601-2, and the apex of the V-shaped structure is a smooth curved portion, which serves as the transition outer conductor contact head 601-5. The second elastic arm 602-2 is formed by bending a metal strip, one end of which is connected to the middle connecting piece 602-1 to form an integral structure, and the other end extends away from the middle connecting piece 602-1, and then bends twice toward the middle connecting piece 602-1, so as to form a V-shaped structure at the end of the second elastic arm 602-2, and the apex of the V-shaped structure is a smooth curved portion, which serves as the transition inner conductor contact head 602-5. The middle connecting piece 602-1 of the transition inner conductor 602 is located at the U-shaped opening of the second semi-enclosed structure 601-1, and the second elastic arm 602-2 is located between the two first elastic arms 601-2.

[0059] When the first elastic arm 601-2 and the second elastic arm 602-2 are in surface-mounted elastic contact with the first elastic sheet 401-4 and the second elastic sheet 402-1 on the RF contact 4, the bending and forming method of the first elastic arm 601-2 and the second elastic arm 602-2 can significantly reduce the signal transmission path. The "surface-mounted" in the "surface-mounted elastic contact" means that when the elastic arm and the elastic sheet are in contact, they are in close contact, and the "elastic contact" means that the first elastic arm 601-2, the second elastic arm 602-2, the first elastic sheet 401-4 and the second elastic sheet 402-1 can be bent and deformed, and the elastic force generated by the deformation can ensure that the elastic arm and the corresponding elastic sheet can be in reliable contact.

[0060] Preferably, Figure 8 As shown, the transfer outer conductor contact head 601-5 of the first elastic arm 601-2 and the transfer inner conductor contact head 602-5 of the second elastic arm 602-2 are provided with a bump 602-4, which can achieve point contact with the first spring sheet 401-4 and the second spring sheet 402-1. The transmission performance of point contact in signal transmission is better than that of surface contact. Furthermore, the bump 602-4 can be gold-plated to enhance the wear resistance of the bump 602-4 when elastically contacting with the first spring sheet 401-4 and the second spring sheet 402-1.

[0061] Preferably, Figure 8 As shown, a barb 602-3 is provided on the middle connecting piece 602-1 of the transition inner conductor 602, and the barb 602-3 is in the shape of a raised triangle or prism. After the barb 602-3 is provided, the transition inner conductor 602 can be better clamped by the barb when installing the transition inner conductor 602, which is convenient for interference assembly and ensures firm strength. Similarly, a similar barb structure is also provided on the second semi-enclosed structure 601-1 of the transition outer conductor 601, which also plays a role in fixing firmly.

[0062] In the present invention, when the integrated module unit 1 and the adapter module unit 2 are docked, the RF contact 4 and the adapter contact 6 are arranged correspondingly. In the corresponding RF contact 4 and the adapter contact 6, the first elastic arm 601-2 is in elastic contact with the first spring sheet 401-4, and the second elastic arm 602-2 is in elastic contact with the second spring sheet 402-1. During the contact process, the deformation amplitude of the elastic arm is greater than the deformation amplitude of the spring sheet, so that there is a certain sliding contact tolerance between the elastic arm and the spring sheet. There is a slight radial sliding between the elastic arm and the spring sheet, which does not affect the normal contact use of the two. That is, a certain range of contact deviation in the radial direction is allowed, and the contact tolerance rate is improved. Compared with the coaxial mutual insertion of the pin and the socket in the prior art, the insertion accuracy threshold is lowered, and there is no need to add an additional multi-level guiding structure to ensure the insertion accuracy, so the structural form of the contact can be simplified. Among them, the coaxial axis direction of the RF outer conductor 401 and the RF inner conductor 402 in the integrated module unit 1 is the axial direction, and the "radial direction" is determined on this basis.

[0063] Preferably, Fig.10 , 11 As shown, in the integrated module unit 1, on the same RF contact 4, two first spring pieces 401-4 and one second spring piece 402-1 are in the same plane, that is, the contact surfaces of the first spring piece 401-4 and the second spring piece 402-1 for contacting the transfer contact 6 are located at Fig.11 Preferably, the contact surfaces of the first elastic pieces 401 - 4 and the second elastic pieces 402 - 1 of all the RF contacts 4 in the integrated module unit 1 are located on the plane S1 .

[0064] In the adapter module unit 2, on the same adapter contact piece 6, the contact heads of the two first elastic arms 601-2 and the one second elastic arm 602-2 are exposed to different lengths of the adapter module insulation base 5 along the axial direction, that is, the adapter outer conductor contact head 601-5 on the first elastic arm 601-2 is located at Fig.11 When the adapter 601-5 is on the plane S2 shown, there is a certain distance between the transfer inner conductor contact head 602-5 of the second elastic arm 602-2 and the plane S2, so that the transfer outer conductor contact head 601-5 and the transfer inner conductor contact head 602-5 are arranged in a staggered manner in the plug-in direction. Preferably, in the adapter module unit 2, all the transfer outer conductor contact heads 601-5 at the same end are located on the plane S2, and the same size of gaps are left between all the transfer inner conductor contact heads 602-5 at the same end and the plane S2, and all the gaps are located on the same side of the plane S2.

[0065] Through the above arrangement, in the process of corresponding contact between the RF contact 4 and the adapter contact 6, the transfer inner conductor 602 of the adapter contact 6 contacts the first spring piece 401-4 and the second spring piece 402-1 in the RF contact 4 before or after the transfer outer conductor 601, thereby forming a time difference of elastic contact. This sequential contact method makes the elastic contact between the RF contact 4 and the adapter contact 6 softer.

[0066] It is understandable that in other embodiments, the contact surfaces of the first spring pieces 401-4 and the second spring pieces 402-1 of all RF contacts 4 in the integrated module unit 1 can also be located on two planes with a certain distance; in the adapter module unit 2, all the adapter outer conductor contact heads 601-5 and all the adapter inner conductor contact heads 602-5 at the same end can also be located on the same plane. In this way, a time difference of elastic contact can also be formed in the process of corresponding contact between the RF contact 4 and the adapter contact 6, so that the elastic contact between the RF contact 4 and the adapter contact 6 is softer.

[0067] Preferably, the arrangement of the two rows of RF contacts 4 and the corresponding transfer contacts 6 in this embodiment is as follows: Fig.12 As shown, in the corresponding RF contacts 4 and transfer contacts 6, the side openings of the first semi-enclosed structure 401-3 and the second semi-enclosed structure 601-1 are oriented in the same direction, and in the same row of contacts, the side openings of the first semi-enclosed structure 401-3 and the second semi-enclosed structure 601-1 are arranged in a staggered direction, that is, in adjacent contacts, the openings between the first semi-enclosed structures 401-3 and the second semi-enclosed structures 601-1 are oriented in opposite directions. This staggered arrangement of the openings is conducive to ensuring isolation and preventing excessive signal leakage.

[0068] Furthermore, when the RF contact 4 is installed on the integrated module insulating base 3, the insulating medium between the RF inner conductor 402 and the RF outer conductor 401 that participates in signal transmission is formed integrally with the integrated module insulating base 3, and the insulating medium is semi-enclosed by the first semi-enclosed structure 401-3, which can effectively prevent the RF contact 4 from rotating. At the same time, the integrated design of the insulating medium and the integrated module insulating base 3 can reduce the module size and simplify the connector.

[0069] Similarly, when the transfer contact 6 is installed on the transfer module insulation base 5, the insulating medium involved in signal transmission between the transfer inner conductor 602 and the transfer outer conductor 601 is integrally formed with the transfer module insulation base 5, and the insulating medium is semi-enclosed by the second semi-enclosed structure 601-1, which can effectively prevent the transfer contact 6 from rotating. At the same time, the integrated design of the insulating medium and the transfer module insulation base 5 can reduce the module size and simplify the connector.

[0070] Embodiment 2: An integrated module unit, such as Fig.13 As shown, it includes an integrated module insulating base 3 and a plurality of radio frequency contacts 4. The structure and arrangement of the radio frequency contacts 4 are the same as those in the first embodiment.

[0071] Embodiment 3: A switching module unit, such as Fig.14 As shown, it includes a switching module insulating base 5 and a switching contact 6. The structure and arrangement of the switching contact 6 are the same as those of the first embodiment.

[0072] The above embodiments are only used to illustrate the technical solutions of the present invention rather than to limit the same. Those skilled in the art should understand that the specific implementation modes of the present invention may be modified or replaced by equivalents with reference to the above embodiments. Any modifications or equivalent replacements that do not depart from the spirit and scope of the present invention are within the scope of protection of the pending claims.
