Description

Technical Field

[0001] This invention belongs to the field of connectors, specifically relating to a multi-channel radio frequency integrated module, an integrated module unit, and an adapter module unit. Background Technology

[0002] Multi-core integrated RF connectors are widely used in aerospace, communications, medical, rail transportation, and industrial fields. With the advent of the big data era, various fields are pursuing miniaturized, integrated, and modular equipment, and there is an urgent need to develop new forms of multi-channel RF modules.

[0003] Generally, existing multi-channel RF integrated modules mainly consist of two parts: RF contacts and an insulating base for integrating multiple RF contacts, such as... Figure 1 and Figure 2 As shown. Whether it's a pin or a socket, the basic components of an RF contact include an inner conductor, an outer conductor surrounding the inner conductor, and an insulator (air can also be used as the insulating medium) between the inner and outer conductors. RF contacts are 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 deficiencies of the prior art shown are as follows:

[0005] (1) When two compatible 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 relatively long, and repeated plugging and unplugging can easily cause significant wear on the inner and outer conductors, resulting in poor signal transmission.

[0006] (2) High interlocking accuracy is required. In order to facilitate interlocking and alignment, multiple levels of guiding structures are often required, resulting in a more complex overall structure.

[0007] (3) Each radio frequency contact needs to have an independent insulator, so the overall structure is complex to assemble and has a low degree of integration. Summary of the Invention

[0008] The purpose of this invention is to provide a multi-channel RF integrated module, an integrated module unit, and an adapter module unit. The multi-channel RF integrated module adopts a three-piece structure design, optimizes the structure of the RF contact components, and achieves reliable connection through the elastic contact of the elastic components, avoiding wear from repeated plugging and unplugging between the contact components, improving structural durability, ensuring transmission quality, and greatly simplifying the system.

[0009] To achieve the above objectives, the first technical solution adopted by the present invention is: a multi-channel radio frequency integrated module, comprising two integrated module units and one adapter module unit. The integrated module unit includes an integrated module insulating base and radio frequency contacts, the radio frequency contacts being arranged on the integrated module insulating base. The adapter module unit includes an adapter module insulating base and adapter contacts, the adapter contacts being arranged on the adapter module insulating base, and the adapter contact heads at both ends of the adapter contacts extending from two opposite end faces on the adapter module insulating base, for surface-mount elastic contact with the radio frequency contact ends of the radio frequency contacts on the same side of the integrated module unit, corresponding one-to-one.

[0010] Its beneficial effects are as follows: The present invention adopts a three-segment system, in which two integrated module units are connected to each other through a transition module unit. Furthermore, the RF contacts on the integrated module unit and the transition contacts on the transition module unit can make one-to-one surface-mount elastic contacts. This ensures reliable contact while avoiding wear from repeated insertion and removal between contacts, improving structural durability and ensuring transmission quality. In addition, the surface-mount elastic contacts can effectively align and reduce the insertion and removal force of pins and sockets, thus solving the problem of large insertion and removal force in multi-channel RF modules.

[0011] Furthermore, the radio frequency contact includes a coaxially arranged radio frequency outer conductor and a radio frequency inner conductor, with the radio frequency outer conductor surrounding the radio frequency inner conductor; the radio frequency outer conductor is provided with an axially extending cantilever and a first spring, the first spring being connected to the end of the cantilever and serving as the radio frequency contact end of the radio frequency outer conductor; the radio frequency inner conductor has a cylindrical structure with a second spring at its end, serving as the radio frequency contact end of the radio frequency inner conductor.

[0012] Its beneficial effects are as follows: the inner and outer RF conductors of the RF contact are in elastic contact with the adapter contact head of the adapter contact by means of a spring, which makes the contact between the adapter contact head and the spring in the radial direction have a certain contact fault tolerance. During the contact process, the adapter contact head can still maintain reliable contact even if it slides slightly on the spring. That is, it allows contact deviation within a certain range in the radial direction, improves the fault tolerance of conductor contact, and lowers the interlocking accuracy threshold compared with the coaxial interlocking in the prior art. It also does not require the addition of an additional multi-stage guiding structure to ensure interlocking accuracy.

[0013] The coaxial axis of the radio frequency outer conductor and the radio frequency inner conductor of the integrated module unit is the axial direction, and the radial direction is established based on this.

[0014] Furthermore, the first spring is perpendicular to the cantilever, and the second spring is perpendicular to the axis of the radio frequency inner conductor.

[0015] Its beneficial effect is that vertical setting allows the spring to have better elasticity.

[0016] Furthermore, a first semi-enclosed structure is provided on the radio frequency outer conductor, which partially encloses the outer side of the columnar portion of the radio frequency inner conductor.

[0017] Its beneficial effects are: the first semi-enclosed structure resembles a U-shaped structure when viewed from the axial direction, and has an opening on its side, which can semi-enclose the radio frequency inner conductor and ensure the isolation of adjacent channels.

[0018] Furthermore, there are two first spring clips and one second spring clip, with the second spring clip located between the two first spring clips.

[0019] Its beneficial effects are: the second spring is located between the two first springs, which can ensure the isolation between adjacent channels, and the impedance can also be adjusted by adjusting the spacing between the springs.

[0020] Furthermore, the adapter contact includes an outer adapter conductor and an inner adapter conductor. The outer adapter conductor has a second semi-enclosed structure in the middle, and at least two first elastic arms are respectively provided at both ends of the axial direction of the second semi-enclosed structure. The inner adapter conductor has a central connecting piece in the middle, and second elastic arms are respectively provided at both ends of the central connecting piece in the length direction. The second semi-enclosed structure partially encloses the outer side of the central connecting piece.

[0021] Its beneficial effects are: the first elastic arm contacts the first elastic piece, and the second elastic arm contacts the second elastic piece, which can realize reliable elastic contact between the integrated module unit and the adapter module unit; the second semi-enclosed structure is similar to a U-shaped structure when viewed from the axial direction, and has an opening on its side, which can semi-enclose the inner conductor of the adapter and ensure the isolation of adjacent channels.

[0022] Furthermore, the first spring arm is formed by bending a metal part, and a smooth bend is provided in the middle of the first spring arm. The smooth bend serves as the contact head of the adapter outer conductor and can be exposed from the end face of the adapter module insulating base for surface-mount elastic contact with the RF contact terminal of the RF outer conductor. The second spring arm is formed by bending a metal part, and a smooth bend is provided in the middle of the second spring arm. The smooth bend serves as the contact head of the adapter inner conductor and can be exposed from the end face of the adapter module insulating base for surface-mount elastic contact with the RF contact terminal of the RF inner conductor.

[0023] Its beneficial effects are: both the first and second spring arms are multi-segment curved structures with the smooth curved part in the middle serving as the 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 radio frequency contact.

[0024] Furthermore, the outer conductor contact head of the first spring arm and / or the inner conductor contact head of the second spring arm are fixedly provided with protrusions for achieving point contact.

[0025] Its beneficial effect is that the protrusions can form point contact with the corresponding spring sheet, and the point contact is superior to the surface contact in terms of signal transmission.

[0026] Furthermore, the middle connecting piece of the inner conductor of the adapter is located at the side opening of the second semi-enclosed structure.

[0027] Its beneficial effects are: it can prevent signal leakage, and at the same time, it can ensure that the bending angle of the second spring arm of the inner conductor of the adapter is large enough, and that the spring force of the second spring arm is sufficient and the recovery is faster.

[0028] Furthermore, two first elastic arms are provided at each end of the second semi-enclosed structure, and one second elastic arm is provided at each end of the middle connecting piece. The outer and inner conductors of the adapter are mounted on the insulating base of the adapter module. The second elastic arm is located between the two first elastic arms on the same side, and the first and second elastic arms have opposite bending directions.

[0029] Its beneficial effects are: the second spring arm is located between the two first spring arms, which can ensure the isolation of adjacent channels, and the impedance can also be adjusted by adjusting the spacing between the spring arms; the first spring arm and the second spring arm have opposite bending directions, which can reduce the size of the transition contact, so that more transition contacts can be arranged on the same size transition module unit, thus which is conducive to the integration and miniaturization of the whole system.

[0030] Furthermore, the integrated module unit is provided with at least one row of radio frequency contacts, and the adapter module unit is provided with adapter contacts in the same number and arrangement as the radio frequency contacts; in the corresponding radio frequency contacts and adapter contacts, the side openings of the first semi-enclosed structure and the second semi-enclosed structure face the same direction, and in the same row of radio frequency contacts or the same row of adapter contacts, the openings of the first semi-enclosed structure on adjacent radio frequency contacts face opposite directions, and the side openings of the second semi-enclosed structure on adjacent adapter contacts face opposite directions.

[0031] Its beneficial effect is that this staggered arrangement of openings helps to ensure isolation and prevents excessive signal leakage.

[0032] Furthermore, in the integrated module unit, the contact end faces of the RF contact are on the same plane; in the adapter module unit, the adapter contact head on the adapter is divided into an adapter outer conductor contact head and an adapter inner conductor contact head. The adapter outer conductor contact heads on the same end of the adapter module unit are on the same plane, and the adapter inner conductor contact head has a certain distance from the plane.

[0033] Alternatively, in an integrated module unit, the RF contact terminal is divided into an RF contact terminal of an outer RF conductor and an RF contact terminal of an inner RF conductor, with the end faces of the RF contact terminals of the outer RF conductor and the RF contact terminals of the inner RF conductor distributed on two planes with a certain distance between them; in an adapter module unit, the adapter contacts on the adapter contacts at the same end of the adapter module unit are on the same plane.

[0034] Its beneficial effect is that during the corresponding contact process between the RF contact and the adapter contact, the inner conductor of the adapter contact contacts the first or second spring in the RF contact first or later than the outer conductor of the adapter contact, thus forming a time difference for elastic contact. This sequential contact method makes the elastic contact between the RF contact and the adapter contact smoother.

[0035] Furthermore, in the integrated module unit, the insulating medium between the inner and outer conductors of the radio frequency contact that participates in radio frequency transmission is integrally formed with the insulating base of the integrated module; in the adapter module unit, the insulating medium between the inner and outer conductors of the adapter contact that participates in radio frequency transmission is integrally formed with the insulating base of the adapter module.

[0036] Its beneficial effects are: the integral molding of the insulating medium and the insulating base can reduce the module size, eliminate the need for additional setting and assembly of the insulator between the inner and outer conductors, help simplify the connector structure and reduce product costs.

[0037] Based on the first solution, the present invention also proposes a second solution: an integrated module unit, comprising an integrated module insulating base and radio frequency (RF) contacts. The RF contacts are arranged on the integrated module insulating base, and each RF contact includes a coaxially arranged RF outer conductor and an RF inner conductor, with the RF outer conductor surrounding the RF inner conductor. The RF outer conductor is provided with an axially extending cantilever and a first spring contact, the first spring contact being connected to the end of the cantilever and serving as the RF contact terminal of the RF outer conductor. The RF inner conductor has a cylindrical structure with a second spring contact at its end, serving as the RF contact terminal of the RF inner conductor.

[0038] Furthermore, the first spring is perpendicular to the cantilever, and the second spring is perpendicular to the axis of the radio frequency inner conductor.

[0039] Furthermore, a first semi-enclosed structure is provided on the radio frequency outer conductor, which partially encloses the outer side of the columnar portion of the radio frequency inner conductor.

[0040] Furthermore, the radio frequency contact end face of the outer radio frequency conductor and the radio frequency contact end face of the inner radio frequency conductor are distributed on two planes with a certain distance between them or on the same plane.

[0041] Furthermore, there are two first spring clips and one second spring clip, with the second spring clip located between the two first spring clips.

[0042] Furthermore, the insulating medium between the inner and outer conductors of the radio frequency contact that participates in radio frequency transmission is integrally formed with the insulating base of the integrated module.

[0043] Based on the first solution, the present invention proposes a third solution: a transfer module unit, including a transfer module insulating base and transfer contacts. The transfer contacts are arranged on the transfer module insulating base, and the transfer contact heads at both ends of the transfer contacts extend from two opposite end faces on the transfer module insulating base, respectively, for surface-mount elastic contact with the RF contacts of the integrated module unit in the multi-channel RF integrated module.

[0044] Furthermore, the adapter contact includes an outer adapter conductor and an inner adapter conductor. The outer adapter conductor has a second semi-enclosed structure in the middle, and at least two first elastic arms are respectively provided at both ends of the axial direction of the second semi-enclosed structure. The inner adapter conductor has a central connecting piece in the middle, and second elastic arms are respectively provided at both ends of the central connecting piece in the length direction. The second semi-enclosed structure partially encloses the outer side of the central connecting piece.

[0045] Furthermore, the middle connecting piece of the inner conductor of the adapter is located at the side opening of the second semi-enclosed structure.

[0046] Furthermore, the first spring arm is formed by bending a metal part, and a smooth bend is provided in the middle of the first spring arm. The smooth bend serves as the contact head of the adapter outer conductor and can be exposed from the end face of the adapter module insulating base for surface-mount elastic contact with the RF contact terminal of the RF outer conductor. The second spring arm is formed by bending a metal part, and a smooth bend is provided in the middle of the second spring arm. The smooth bend serves as the contact head of the adapter inner conductor and can be exposed from the end face of the adapter module insulating base for surface-mount elastic contact with the RF contact terminal of the RF inner conductor.

[0047] Furthermore, the outer conductor contact head of the first spring arm and / or the inner conductor contact head of the second spring arm are fixedly provided with protrusions for achieving point contact.

[0048] Furthermore, the adapter contact on the adapter is divided into an outer conductor contact and an inner conductor contact. The end faces of the outer conductor contact located at the same end of the adapter module unit are on the same plane, and the end face of the inner conductor contact is at a certain distance from the plane; or, the end faces of the outer conductor contact and the inner conductor contact located at the same end of the adapter module unit are in the same plane.

[0049] Furthermore, two first elastic arms are provided at each end of the second semi-enclosed structure, and one second elastic arm is provided at each end of the middle connecting piece. The outer and inner conductors of the adapter are mounted on the insulating base of the adapter module. The second elastic arm is located between the two first elastic arms on the same side, and the first and second elastic arms have opposite bending directions.

[0050] Furthermore, the insulating medium between the inner and outer conductors of the adapter contact that participates in radio frequency transmission is integrally formed with the insulating base of the adapter module.

[0051] The beneficial effects of this invention are as follows: The multi-channel RF integrated module of this invention adopts a three-segment system. Through the surface-mount elastic contact of the RF contact and the adapter contact, it effectively solves the radial tolerance problem of traditional round pin and round hole contact components. This not only ensures effective alignment but also reduces the insertion and extraction force of traditional round pins and round holes, solving the problem of large insertion and extraction force in multi-channel modules, while ensuring reliable contact between the inner and outer conductors. In addition, the semi-enclosed structure also ensures the isolation between adjacent channels. Attached Figure Description

[0068] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments, but this should not be construed as limiting the invention in any way.

[0069] Example 1: Refer to Appendix Figure 3 As shown, a multi-channel radio frequency integrated module includes an integrated module unit 1 and an adapter module unit 2. The integrated module unit 1 includes an integrated module insulating base 3 and multiple radio frequency contacts 4. The adapter module unit 2 includes an adapter module insulating base 5 and adapter contacts 6. Two integrated module units 1 are provided, located on opposite sides of the adapter module unit 2, and signal conduction between the two integrated module units 1 is achieved through the adapter module unit 2.

[0070] In the integrated module unit 1, the plurality of radio frequency contacts 4 are arranged on the integrated module insulating base 3 according to a certain pattern. The contact ends of the radio frequency contacts 4 are 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 radio frequency (RF) contacts 4 are arranged in two rows on the integrated module insulating base 3, with each row consisting of seven RF contacts 4 spaced apart along the length 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 needs.

[0071] In the adapter module unit 2, multiple adapter contacts 6 are installed and arranged according to the arrangement pattern of the radio frequency contacts 4 in the integrated module unit 1, so that the two ends of the adapter contacts 6 are exposed from the opposite sides of the adapter module insulating base 5, and respectively contact the radio frequency contacts 4 on the two integrated module units 1.

[0072] The following is combined with Figure 4 , 5The structure of the RF contact 4 is described below. The RF contact 4 includes an outer RF conductor 401 and an inner RF conductor 402, which are separated by an insulating structure when mounted on the integrated module insulating base 3. The outer RF conductor 401 is a coaxial structure made of rolled metal sheet, and is divided into a terminal 401-1, a hollow cylinder 401-2, and a first semi-enclosed structure 401-3 along the axial direction of the outer RF conductor 401. The hollow cylinder 401-2 is located in the middle of the outer RF 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 along the axial direction. The first semi-enclosed structure 401-3 and the hollow cylinder 401-2 are coaxially arranged. The semi-enclosed structure 401-3 has a U-shaped structure. Two axially extending cantilever arms are provided on the edge of the first semi-enclosed structure 401-3 opposite to the hollow cylinder 401-2. The end of the cantilever arm is provided with a first spring piece 401-4. The first spring piece 401-4 is integral with the corresponding cantilever arm and is perpendicular to it. Therefore, the first spring piece 401-4 can be formed by bending the end of the cantilever arm by 90°. The radio frequency inner conductor 402 has a cylindrical structure, and a second spring piece 402-1 is provided at one end. The second spring piece 402-1 is perpendicular to the axis of the radio frequency inner conductor 402. The radio frequency inner conductor 402 is inserted into the radio frequency outer conductor 401, and the first semi-enclosed structure 401-3 forms a semi-enclosure of the radio frequency inner conductor 402. After the radio frequency outer conductor and the radio frequency inner conductor are installed on the integrated module insulating base 3, the two first spring contacts are located on both sides of the second spring contact, and all three spring contacts are exposed from the contact end face of the integrated module insulating base 3 for surface elastic contact with the corresponding adapter contact 6 on the adapter module unit 2.

[0073] The following is combined with Figure 6-9The structure of the adapter contact 6 is described below. The adapter contact 6 includes an outer adapter conductor 601 and an inner adapter conductor 602, both mounted on the adapter module insulating base 5 and separated by the insulating structure of the adapter module insulating base 5. The outer adapter conductor 601 has a second semi-enclosed structure 601-1 formed by bending a metal sheet in its middle. The second semi-enclosed structure 601-1 is U-shaped, with two bent elastic arms at each end of its axial direction, serving as 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 parallel and spaced apart. The inner adapter conductor 602 has a sheet-like structure in its middle, serving as a middle connecting piece 602-1. Each end of the middle connecting piece 602-1 has a bent elastic arm, serving as a second elastic arm 602-2. When the inner conductor 602 is assembled with the outer conductor 601, the middle connecting piece 602-1 of the inner conductor 602 is located at the U-shaped opening of the second semi-enclosed structure 601-1. This can prevent signal leakage and also ensure that the bending angle of the second elastic arm 602-2 of the inner conductor 602 is large enough, thereby ensuring that the second elastic arm 602-2 has sufficient elasticity and can recover its shape more quickly after elastic deformation.

[0074] Specifically, such as Figure 9 As shown, the second semi-enclosed structure 601-1 on the adapter outer conductor 601 includes a central substrate 601-3 and central side wing plates 601-4 located on opposite sides of the central substrate 601-3. The central substrate 601-3 and the two central side wing plates 601-4 are an integral structure. The two central 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 it is connected to the central substrate 601-3 to form an integral structure, and the other end extends away from the central substrate 601-3. Then it is bent twice towards the second semi-enclosed structure 601-1 to form a V-shaped structure at the end of the first elastic arm 601-2. The apex of the V-shaped structure is a smooth bend, which serves as the adapter outer conductor contact head 601-5. The second elastic arm 602-2 is formed by bending a metal strip. One end of it is connected to the central connecting piece 602-1 to form an integral structure, and the other end extends away from the central connecting piece 602-1, and then bends twice towards the central connecting piece 602-1 to form a V-shaped structure at the end of the second elastic arm 602-2. The apex of the V-shaped structure is a smooth bend, which serves as the inner conductor contact head 602-5. The central connecting piece 602-1 of the 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.

[0075] When the first elastic arm 601-2 and the second elastic arm 602-2 are in surface-mount elastic contact with the first spring piece 401-4 and the second spring piece 402-1 on the radio frequency 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 term "surface-mount elastic contact" refers to a close-fitting contact when the elastic arm and the spring piece are in contact, and "elastic contact" means that the first elastic arm 601-2, the second elastic arm 602-2, the first spring piece 401-4, and the second spring piece 402-1 can be bent and deformed, and the elastic force generated by the deformation can ensure reliable contact between the elastic arm and the corresponding spring piece.

[0076] Preferred, such as Figure 8 As shown, the outer conductor contact 601-5 of the first spring arm 601-2 and the inner conductor contact 602-5 of the second spring arm 602-2 are provided with protrusions 602-4, which can achieve point contact with the first spring piece 401-4 and the second spring piece 402-1. Point contact has better signal transmission performance than surface contact. Furthermore, gold plating can be applied to the protrusions 602-4 to enhance the wear resistance of the protrusions 602-4 when they make elastic contact with the first spring piece 401-4 and the second spring piece 402-1.

[0077] Preferred, such as Figure 8 As shown, the connecting piece 602-1 in the middle of the inner conductor 602 is provided with barbs 602-3, which are raised triangular or prismatic in shape. The barbs 602-3 allow for better clamping of the inner conductor 602 during installation, facilitating interference fit and ensuring robust strength. Similarly, a similar barb structure is provided on the second semi-enclosing structure 601-1 of the outer conductor 601, also serving a secure fixing function.

[0078] In this invention, when the integrated module unit 1 and the adapter module unit 2 are connected, the radio frequency contact 4 and the adapter contact 6 are arranged correspondingly. In the corresponding radio frequency contact 4 and adapter contact 6, the first spring arm 601-2 elastically contacts the first spring piece 401-4, and the second spring arm 602-2 elastically contacts the second spring piece 402-1. During the contact process, the deformation amplitude of the spring arm is greater than that of the spring piece, allowing for a certain degree of sliding contact tolerance between the spring arm and the spring piece. A slight radial slippage between the spring arm and the spring piece does not affect their normal contact use, thus allowing a certain range of contact deviation in the radial direction and improving the contact tolerance rate. Compared to the coaxial interlocking of pins and sockets in the prior art, this lowers the interlocking accuracy threshold and eliminates the need for additional multi-stage guiding structures to ensure interlocking accuracy, thereby simplifying the contact structure. Specifically, the coaxial axis direction of the radio frequency outer conductor 401 and the radio frequency inner conductor 402 in the integrated module unit 1 is the axial direction, and the "radial direction" is determined based on this.

[0079] Preferred, such as Figure 10 , 11 As shown, in the integrated module unit 1, on the same RF contact 4, two first spring contacts 401-4 and one second spring contact 402-1 are located on the same plane, that is, the contact surfaces on the first spring contacts 401-4 and the second spring contacts 402-1 for contacting the adapter contact 6 are located at... Figure 11 On the plane S1 shown. Preferably, the contact surfaces of the first spring 401-4 and the second spring 402-1 of all radio frequency contacts 4 in the integrated module unit 1 are located on the plane S1.

[0080] In the adapter module unit 2, on the same adapter contact 6, the contact heads of the two first spring arms 601-2 and the one second spring arm 602-2 protrude axially from the insulating base 5 of the adapter module by different lengths. That is, the adapter outer conductor contact head 601-5 on the first spring arm 601-2 is located at... Figure 11 When the second spring arm 602-2 is on plane S2, the inner conductor contact 602-5 is at a certain distance from plane S2, so that the outer conductor contact 601-5 and the inner conductor contact 602-5 are staggered in the interlocking direction. Preferably, in the adapter module unit 2, all outer conductor contacts 601-5 at the same end are located on plane S2, and all inner conductor contacts 602-5 at the same end have a gap of the same size between them and plane S2, and all gaps are located on the same side of plane S2.

[0081] With the above settings, during the corresponding contact process between the RF contact 4 and the adapter contact 6, the inner conductor 602 of the adapter contact 6 contacts the first spring 401-4 and the second spring 402-1 in the RF contact 4 first or later than the outer conductor 601, thus forming a time difference for elastic contact. This sequential contact method makes the elastic contact between the RF contact 4 and the adapter contact 6 more gentle.

[0082] It is understood that, in other embodiments, the contact surfaces of the first spring tab 401-4 and the second spring tab 402-1 of all RF contacts 4 in the integrated module unit 1 can also be located on two planes with a certain distance between them; in the adapter module unit 2, all adapter outer conductor contacts 601-5 and all adapter inner conductor contacts 602-5 on the same end can also be located on the same plane. This also allows for the formation of a time difference in elastic contact during the corresponding contact process between the RF contact 4 and the adapter contact 6, making the elastic contact between the RF contact 4 and the adapter contact 6 smoother.

[0083] Preferably, in this embodiment, the arrangement of the two rows of radio frequency contacts 4 and the corresponding transition contacts 6 is as follows: Figure 12 As shown, in the corresponding RF contact 4 and transition contact 6, the side openings of the first semi-enclosed structure 401-3 and the second semi-enclosed structure 601-1 face the same direction. In the same row of contacts, the side openings of both the first semi-enclosed structure 401-3 and the second semi-enclosed structure 601-1 are arranged in an alternating manner; that is, in adjacent contacts, the openings between the first semi-enclosed structures 401-3 and between the second semi-enclosed structures 601-1 face opposite directions. This alternating arrangement of openings helps ensure isolation and prevents excessive signal leakage.

[0084] Furthermore, when the RF contact 4 is mounted on the integrated module insulating base 3, the insulating medium involved in signal transmission between the RF inner conductor 402 and the RF outer conductor 401 is integrally formed with the integrated module insulating base 3, and this insulating medium is partially surrounded 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.

[0085] Similarly, when the adapter contact 6 is mounted on the adapter module insulating base 5, the insulating medium involved in signal transmission between the inner conductor 602 and the outer conductor 601 is integrally formed with the adapter module insulating base 5, and this insulating medium is partially surrounded by the second semi-enclosed structure 601-1, which can effectively prevent the adapter contact 6 from rotating. At the same time, the integrated design of the insulating medium and the adapter module insulating base 5 can reduce the module size and simplify the connector.

[0086] Example 2: An integrated module unit, such as Figure 13 As shown, it includes an integrated module insulating base 3 and multiple radio frequency contacts 4. The structure and arrangement of the radio frequency contacts 4 are the same as in Embodiment 1.

[0087] Example 3: A transition module unit, such as Figure 14 As shown, it includes an insulating base 5 for the adapter module and an adapter contact 6. The structure and arrangement of the adapter contact 6 are the same as in Embodiment 1.

[0088] The above embodiments are only used to illustrate the technical solutions of the present invention and are not intended to limit it. Those skilled in the art should understand that modifications or equivalent substitutions can be made to the specific implementation of the present invention with reference to the above embodiments. Any modifications or equivalent substitutions that do not depart from the spirit and scope of the present invention are within the protection scope of the pending claims.
