For example, Chinese patent No. CN202123000813.5 discloses a heat-conducting and electrically-conducting multifunctional connector, which realizes the connection between the two layers by using an elastic connector and supports the metal elastic needle by using a heat-conducting and insulating medium.

The multi-channel button microwave sealing adapter module 300 includes a first structural assembly 300a, a PCB 300b (Printed Circuit Board), and a second structural assembly 300c.

[0047] See also Figure 4 and Figure 5 In one embodiment, the first structural assembly 300a includes a first structural member 310 and an RF coaxial sealed connector 320. The first structural member 310 has a first through hole 302. The RF coaxial sealed connector 320 is used to connect to the first through hole 302 of the first structural member 310. The RF coaxial sealed connector 320 includes a rigid outer conductor 321, an insulating dielectric member 322, a rigid inner conductor 324, a first solid button 325, and a first hollow button 327.

[0049] Referring to Figure 4 and Figure 5 In one embodiment, the first solid hair buckle 325 is connected with the rigid inner conductor 324. As shown in Figure 6 and Figure 6a , the two surfaces of the PCB 300b are provided with solid pads 303 and ground sheets 305 which are arranged around the solid pads and are insulated from the solid pads. In this embodiment, the ground sheets are arranged around the solid pads in an insulating manner. The first solid hair buckle is elastically abutted against the solid pad on the first surface of the PCB, and the first hollow hair buckle is elastically abutted against the ground sheet on the first surface of the PCB. The first solid hair buckle 325 is elastically abutted against the solid pad 303, so that the first solid hair buckle 325 is electrically connected with the solid pad 303. The first hollow hair buckle 327 is connected with the end of the second end of the rigid outer conductor 321, and is arranged around the first solid hair buckle 325. The first hollow hair buckle 327 is used to be elastically abutted against the solid pad 303 in the state that the first solid hair buckle 325 is elastically abutted against the solid pad 303, that is, the first hollow hair buckle 327 and the first solid hair buckle 325 are both elastically abutted against the solid pad 303, so that the solid pad 303 is solderless interconnected with the radio frequency coaxial sealed connector 320. In this embodiment, the first hollow hair buckle 327 is arranged around the first solid hair buckle 325, and there is a gap between the first hollow hair buckle 327 and the first solid hair buckle 325.

[0050] As shown in Figure 4 and Figure 6As shown, in one embodiment, the second structure assembly 300c includes a second structure 330 and a double floating radio frequency coaxial connector 340, the second structure 330 is provided with a second through hole 307, and the double floating radio frequency coaxial connector 340 is arranged in the second through hole 307 and connected with the second structure 330; one end of the double floating radio frequency coaxial connector 340 is respectively elastically abutted against the solid pad and the ground sheet of the second surface of the PCB, and the other end of the double floating radio frequency coaxial connector 340 is used for elastically abutting against the conductive substrate 200, so that the double floating radio frequency coaxial connector 340 is respectively electrically connected with the anti-pad 305 and the conductive substrate 200.

[0051] The above-mentioned electric contact connection device 10, the multi-channel hair buckle microwave sealing adapter module 300 and the radio frequency coaxial sealing connector 320, when assembled and used, the rigid outer conductor 321 is welded in the first through hole 302, that is, the rigid outer conductor 321 is located in the first through hole 302 and welded with the first structure 310, so that the rigid outer conductor 321 is sealingly connected in the first through hole 302, so that the internal channel of the multi-channel hair buckle microwave sealing adapter module 300 is sealed, and because the insulating medium 322 is located in the fixed hole 3212 and is sintered and fixedly connected with the rigid outer conductor 321, the insulating medium body is sleeved with the rigid inner conductor 324 and is sintered and fixedly connected with the rigid inner conductor 324, so that the rigid medium body is sintered and fixedly assembled in the fixed hole 3212 through the insulating medium body, and the internal channel of the multi-channel hair buckle microwave sealing adapter module 300 is better sealed, the structural air tightness of the electric contact connection device 10 is improved, and the problem that the conductive substrate 200 is easily oxidized to cause the electric contact connection device 10 to have poor service life is avoided, especially for the transmission of multi-channel microwave signals.

[0052] As Figure 5As shown, further, since the first solid button is connected to the rigid inner conductor, and the first solid button elastically abuts against the solid pad of the PCB, the RF coaxial sealed connector also includes a first hollow button. The first hollow button is connected to the end of the second end of the rigid outer conductor, and the first hollow button is arranged around the first solid button. The first hollow button elastically abuts against the grounding plate of the PCB while the first solid button elastically abuts against the solid pad. This makes the rigid outer conductor reliably electrically connected to the grounding plate and the rigid inner conductor reliably electrically connected to the solid pad, giving the RF coaxial sealed connector better floating performance. This also gives the RF coaxial sealed connector better tolerance performance when abutting against the solid pad, and makes the RF coaxial sealed connector reliably grounded. This allows the multi-channel button microwave sealed adapter module with the RF coaxial sealed connector to be reliably electrically connected to the antenna assembly and conductive substrate, improving the integrity of signal transmission, that is, improving the continuity of signal transmission, and thus improving the reliability of signal transmission of electrical contact connection devices, especially for the transmission of multi-channel microwave signals.

[0053] like Figure 6a As shown, in one embodiment, a stripline 309 is provided within the PCB 300b, and the solid pads 303 on both sides of the PCB 300b are electrically connected via the stripline. In this embodiment, the stripline has a 50Ω impedance matching to ensure that the adapter module has good adapter functionality.

[0054] In one embodiment, the multi-channel button-type microwave sealed adapter module 300 can simultaneously transmit multiple channels of microwave signals. One end of the multi-channel button-type microwave sealed adapter module 300 can be interconnected with the antenna assembly 100, and the other end can be interconnected with the conductive substrate 200, allowing the antenna assembly 100 and the conductive substrate 200 to be floatingly interconnected. In this embodiment, there are multiple RF coaxial sealed connectors 320 and solid pads 303. The first solid button 325 of each RF coaxial sealed connector 320 abuts against the corresponding solid pad 303, and the first hollow button of each RF coaxial sealed connector 320 abuts against the grounding plate, ensuring that the rigid outer conductor of each RF coaxial sealed connector 320 is reliably grounded, thus realizing the transmission of multi-channel microwave signals. The multi-channel button-type microwave sealed adapter module achieves multi-channel position expansion or position transformation through the adapter PCB 300b, improving the applicability and ease of use of the multi-channel button-type microwave sealed adapter module.

[0055] like Figure 1 As shown, in one embodiment, the conductive substrate 200 can be a ceramic substrate or a PCB 300b. In this embodiment, the conductive substrate 200 is a low-temperature co-fired ceramic substrate.

[0056] Furthermore, the first structural assembly 300a, PCB 300b and the second structural assembly 300c are sequentially locked and fixed together by a number of screws, and the first structural assembly 300a, PCB 300b and the second structural assembly 300c are sequentially positioned by locating pins, so that the first structural assembly 300a, PCB 300b and the second structural assembly 300c are reliably assembled and fixed.

[0057] like Figure 5 and Figure 7 As shown, in one embodiment, a receiving hole 3242 is formed at the end of the rigid inner conductor 324 adjacent to the second end. The first solid button 325 is located in the receiving hole 3242 and connected to the rigid inner conductor 324. The first solid button 325 and the rigid inner conductor 324 are interference-fitted to avoid the problem of the first solid button 325 and the rigid inner conductor 324 detaching from each other, so that the first solid button 325 and the rigid inner conductor 324 are reliably fixedly connected.

[0058] like Figure 7 As shown, in one embodiment, one end of the first solid button 325 protrudes from the end of the rigid inner conductor 324, so that the first solid button 325 can elastically abut against the solid pad 303.

[0059] like Figure 7 As shown, in one embodiment, the first solid button 325 protrudes from the end of the rigid inner conductor 324 and is flush with the first hollow button 327, so that the first solid button 325 can reliably and elastically abut against the surface of the solid pad 303 when the first hollow button 327 abuts against the grounding plate. In addition, the first solid button 325 and the first hollow button 327 are both elastic, thereby enabling the RF coaxial sealed connector to have better tolerance performance.

[0060] like Figure 7 As shown, the first hollow button 327 is further connected to the end of the second end of the rigid outer conductor 321 by gluing or welding to the end of the second end of the rigid outer conductor 321.

[0061] like Figure 8As shown in the figure, in one of the embodiments, the rigid inner conductor 324 is formed with a convex 3244 in the accommodating hole 3242, the convex 3244 abuts against the first solid hair button 325, avoiding the rigid inner conductor 324 and the first solid hair button 325 from being separated from each other, so that the rigid inner conductor 324 can be reliably connected to the first solid hair button 325, the convex 3244 neither affects the resilience of the first solid hair button 325, nor fixes the first solid hair button 325 in the accommodating hole 3242. In the embodiment, the rigid inner conductor 324 can be formed with the convex 3244 in the accommodating hole 3242 through a riveting process. It can be understood that the number of the convex 3244 can be one or more than two.

[0062] As shown in the figure, Figure 7 In one of the embodiments, the rigid outer conductor 321 and the rigid inner conductor 324 are fixed by sintering through the insulating medium 322, so that the rigid outer conductor 321 and the rigid inner conductor 324 are sealingly connected.

[0063] As shown in the figure, Figure 5 and Figure 7 In one of the embodiments, the RF coaxial sealing connector 320 further comprises an insulating abutting member 323, the insulating abutting member 323 is sleeved on the end portion of the first solid hair button 325 adjacent to the second end, so as to abut against the solid pad 303, so that the first solid hair button 325 and the first hollow hair button 327 are reliably and insulatively arranged, and at the same time, the first solid hair button 325 and the first hollow hair button 327 can both elastically abut against the solid pad 303. Further, the insulating abutting member 323 is in interference connection with the first solid hair button 325, and the outer peripheral wall of the insulating abutting member 323 is in interference connection with the inner wall of the first hollow hair button 327, so that the insulating abutting member 323 is reliably and fixedly connected with the first solid hair button 325, and at the same time, the inner diameter of the insulating abutting member 323 is solidly matched with the 50-ohm impedance of the first hollow hair button 327; in addition, the outer peripheral wall of the insulating abutting member 323 is in interference connection with the inner wall of the first hollow hair button 327, that is, the outer peripheral wall of the insulating abutting member 323 is in interference fit with the inner wall of the first hollow hair button 327, without affecting the resilience of the first hollow hair button 327, and at the same time, the first hollow hair button 327 is better fixed in the insulating abutting member 323. In one of the embodiments, the insulating abutting member 323 is an engineering plastic abutting member.

[0064] As shown in the figure, Figure 3 and Figure 6 In one of the embodiments, the second structural member 300c further comprises a grounding elastic needle 350; the grounding elastic needle 350 is movably arranged in the second structural member 330, and is used for elastically abutting against the grounding end of the conductive substrate 200, so that the grounding elastic needle 350 is reliably grounded with the conductive substrate 200, and at the same time, the grounding elastic needle 350 and the conductive substrate 200 have better shielding performance at the abutting position.

[0065] As shown in Figure 6 and Figure 9 In one embodiment, the double floating radio frequency coaxial connector 340 includes a floating connector body 342, two second solid pogo pins 344 and two second hollow pogo pins 346, the two second solid pogo pins 344 are respectively protruded from two ends of the floating connector body 342, the two second hollow pogo pins 346 are respectively protruded from two ends of the floating connector body 342, and each second hollow pogo pin 346 is arranged around the corresponding second solid pogo pin 344; one of the second solid pogo pins elastically abuts against the solid pad on the second surface of the PCB, one of the second hollow pogo pins elastically abuts against the ground sheet on the second surface of the PCB, the other of the second solid pogo pins elastically abuts against the solid pad on the conductive substrate, and one of the second hollow pogo pins elastically abuts against the ground sheet on the conductive substrate, so that the two ends of the double floating radio frequency coaxial connector 340 elastically abut against the PCB and the conductive substrate respectively, thereby the double floating radio frequency coaxial connector 340 has better floating performance, and realizes the solder-free interconnection between one end of the double floating radio frequency coaxial connector 340 and the PCB and the solder-free interconnection between the other end of the double floating radio frequency coaxial connector 340 and the conductive substrate. In this embodiment, the floating connector body 342 is arranged in the second through hole 307 and connected with the second structural member 330. When the connector end face is stressed, not only the two second hollow pogo pins 346 at the two ends of the double floating radio frequency coaxial connector 340 are in a compressed state, but also the outer conductor of the double floating radio frequency coaxial connector 340 reliably contacts the interconnected PCB 300b, further ensuring the integrity of signal transmission of the multi-channel pogo pin microwave sealed adapter module 300.

[0066] As shown in Figure 9 and Figure 10 Further, the outer wall of the floating connector body 342 is provided with a boss 3422, and the floating connector body 342 is gap-connected with the second structural member 330, i.e. the floating connector body 342 is gap-fitted with the second structural member 330.

[0067] It should be noted that in one of the embodiments, the two surfaces of the PCB are provided with ground sheets and solid pads, wherein the ground sheet on the first surface of the PCB is a first ground sheet, and the solid pad on the first surface of the PCB is a first solid pad, wherein the ground sheet on the second surface of the PCB is a second ground sheet, and the solid pad on the second surface of the PCB is a second solid pad. The number of the first solid pads and the second solid pads is multiple, and the multiple first solid pads are respectively electrically connected with the corresponding second solid pads. For multi-channel microwave signal transmission, the number of the double-floating radio frequency coaxial connectors 340 and the radio frequency coaxial sealed connectors 320 is multiple, and the multiple first solid pads and the second solid pads are integrally arranged on the same PCB 300b, so that the integration degree of the PCB 300b is high, which has higher requirements for the floating performance and tolerance performance of the multi-channel microstrip microwave sealed adapter module 300. Specifically, the multiple first solid pads are located on the first surface of the PCB, and the multiple second solid pads are located on the second surface of the PCB.
