Abstract
Description
Technical Field
[0001] The present invention relates to an RF connection component, in particular to a high-frequency RF connection component and a high-frequency RF jumper and a board-end connector thereof. Background Art
[0002] In recent years, RF connecting components have been widely used in various electronic products. Generally speaking, the antenna module of a mobile communication device is composed of an RF connecting component. The RF connecting component transmits RF signals through the line-end connector of the RF jumper and the board-end connector.
[0003] Regarding the board connector, such as Figure 1 As shown, the board-end connector 2 is welded on the circuit substrate, and the middle part of the board-end connector 2 is provided with a columnar board-end center terminal 21 and a cylindrical board-end shielding terminal 23. The board-end shielding terminal 23 is arranged around the board-end center terminal 21. The bottom side of the board-end center terminal 21 extends a board-end center terminal pin 22, and the bottom side of the board-end shielding terminal 23 extends a board-end shielding terminal pin 24. When in use, these pins 22 and 24 can be connected to the specified position of the circuit substrate by SMT welding or other connection methods. Regarding the line-end connector, such as Figure 2 As shown, the line end connector 3 includes a line end center terminal 31 and a line end shield terminal 32. The line end center terminal 31 is electrically connected to the cable center conductor (commonly known as the core wire, not shown) of the coaxial cable, and the line end shield terminal 32 is electrically connected to the outer conductor (not shown) of the coaxial cable. The line end connector 3 can be inserted into Figure 1 The board-side connector 2 shown in the figure electrically connects the line-side center terminal 31 with the board-side center terminal 21 , and electrically connects the line-side shielding terminal 32 with the board-side shielding terminal 23 , so that the RF signal of the coaxial cable is connected to the circuit substrate.
[0004] For the mating process of the existing wire-end connector and the board-end connector, please refer to Figure 3 The line end connector 3 moves downward from top to bottom to engage with the board end connector 2, and the engagement between the line end connector 3 and the board end connector 2 is maintained by the interference force (also called engagement force) generated by the contact between the board end connector 2 and the line end connector 3 (see Figure 4 ).
[0005] However, due to the demand for thinner mobile communication devices in recent years, the overall height of the line-end connector and the board-end connector used with it has been continuously required to be reduced. For example, the overall height of the line-end connector and the board-end connector has been required to be reduced from the earliest 3.5mm to 1.2mm, and now there is a requirement of less than 1.0mm, and even a requirement of 0.60mm, which is the same height as other components. The smaller the overall height of the line-end connector and the board-end connector, the more it conforms to the development trend of thinning electronic products, but the insufficient contact area between the line-end connector and the board-end connector (i.e., insufficient interference height) will cause insufficient fitting force between the connectors, resulting in the line-end connector being easily detached from the board-end connector when impacted by external force, affecting the normal operation of the electronic product, and even causing damage to the electronic product, which creates great difficulties in the design of RF connection components.
[0006] Furthermore, the existing RF connection components have poor shielding effects due to the limitations of structural design, such as Figure 3 The shielding terminal 32 shown has a hole 321, which makes the shielding effect poor, and can only be used to transmit RF signals below 6 GHz, such as GPS or WIFI. However, according to the WiGig specification of the 5G generation scheduled to be fully introduced in 2020, high-frequency RF signals from 15 GHz to 55-67 GHz will be used, and even ultra-high frequency RF signals in the 80 GHz band will be used for car automatic navigation.
[0007] Therefore, it is necessary and urgent to develop an RF connection component that can reduce the overall height and transmit above the 15 GHz frequency band or even above the 67 GHz frequency band. It has become a technical issue that the industry is eager to challenge and overcome. Summary of the invention

DETAILED DESCRIPTION
[0035] The following content will be combined with the drawings of the specification to illustrate the technical content of the present invention through specific embodiments. Those skilled in the art can easily understand other advantages and effects of the present invention from the contents disclosed in this specification. The present invention can also be implemented or applied through other different specific embodiments. The details in this specification can also be modified and changed in various ways based on different viewpoints and applications without departing from the spirit of the present invention. In particular, the proportions and relative positions of the various components in the drawings are only for exemplary purposes and do not represent the actual situation of the implementation of the present invention.
[0036] In order to make the disclosed content more concise and easier to understand, the components with the same or similar functions will be described using the same symbols, and the description of the same or equivalent features will be omitted.
[0037] For the technical disclosure of the present invention, please refer to Figures 5 to 18As shown in the figures, the high-frequency RF connection component 1 of the present invention includes: a high-frequency RF jumper 4, a board-end connector 13 and a circuit substrate 14, wherein the high-frequency RF jumper 4 is composed of at least a coaxial cable 11 and a line-end connector 12. In the present invention, the coaxial cable 11 includes a cable center conductor 111 and a cable shield conductor 112, and the line-end connector 12 has a line-end insulator 121 and a line-end shield terminal 122, wherein the cable center conductor 111 and the cable shield conductor 112 are electrically isolated by the presence of insulating material, so that the cable shield conductor 112 can provide electrical shielding for the cable center conductor 111, so that the cable center conductor 111 can transmit high-frequency RF signals. A cable center conductor end contact portion 1112 is provided at the end of the cable center conductor body 1111 of the cable center conductor 111, which can be selectively, as Fig.11 In the illustrated embodiment, the cable center conductor body 1111 is inserted into the wire end insulator 121, and the cable center conductor terminal contact portion 1112 extends out of the wire end insulator 121, and the intersection angle between the cable center conductor terminal contact portion 1112 and the cable center conductor body 1111 is approximately ninety degrees, so that the cable center conductor 111 has an L-shaped cross-section, and the cable center conductor terminal contact portion 1112 is provided to directly electrically contact the circuit substrate 14 without passing through other conductors, so as to reduce the attenuation of the high-frequency RF signal of the cable center conductor 111 during transmission to the circuit substrate 14. Since the cable center conductor body 1111 is inserted into the wire end insulator 121, the wire end insulator 121 needs to be supported to prevent the cable center conductor body 1111 from being deformed and broken due to displacement of the wire end insulator 121, or to prevent the cable center conductor terminal contact portion 1112 from being displaced and unable to directly and effectively electrically contact the circuit substrate 14, thereby affecting the transmission of the high-frequency RF signal. In this regard, it is possible to selectively, as Figure 7 In the illustrated embodiment, the line end shielding terminal 122 is further provided with a line end insulator support portion 1222, which extends along the outer wall of the line end insulator 121 and embraces the line end insulator 121 to provide rigid support for the line end insulator 121, and positions the line end insulator 121 to ensure that the cable center conductor body 1111 will not be broken and to ensure that the cable center conductor end contact portion 1112 can directly electrically contact the circuit substrate 14.
[0038] like Fig.16In the embodiment shown, the line end shielding terminal 122 includes a line end shielding conductor riveting portion 1221, and the line end shielding conductor riveting portion 1221 is riveted to the cable shielding conductor 112 of the coaxial cable 11, and is in direct electrical contact with the cable shielding conductor 112 of the coaxial cable 11, so that the line end shielding terminal 122 is electrically connected to the cable shielding conductor 112 of the coaxial cable 11. In this way, the coaxial cable 11 and the line end connector 12 of the present invention can form a kind of cooperating with the board end connector 13. Figure 6 The high-frequency RF jumper 4 shown transmits high-frequency RF signals by directly and electrically contacting the cable center conductor 111 of the coaxial cable 11 with the circuit substrate 14 , and provides electrical shielding for the cable center conductor 111 transmitting the high-frequency RF signal through the line end shielding terminal 122 .
[0039] Regarding the board connector 13, Figures 5 to 8 In the illustrated embodiment, the board-end connector 13 includes a board-end insulator 131, a board-end shielding terminal 132, and a board-end metal cover 133, wherein the board-end insulator 131 has a first board-end through-groove 1311 and a second board-end through-groove 1312 that are connected. The board-end shielding terminal 132 has a first board-end shielding body 1321 and a second board-end shielding body 1322, wherein the first and second board-end shielding bodies 1321 and 1322 are respectively disposed on the groove walls of the first and second board-end through-groove 1311 and 1312, thereby respectively providing electrical shielding for the first and second board-end through-groove 1311 and 1312. The high-frequency RF jumper 4 provided in the present invention can be inserted into the board-end connector 13, so that the cable center conductor end contact portion 1112 of the coaxial cable 11 extends toward the direction of the circuit substrate 14, and directly electrically contacts the circuit substrate 14 in the first board-end through-groove 1311 without passing through other conductors.
[0040] The board end metal cover 133 includes a board end metal cover body 1331, a board end cover lifting structure 1332 and a board end cover buckling structure 1333. The board end cover lifting structure 1332 is, for example, a folding structure disposed on the board end metal cover body 1331, so as to provide a folding and lifting of the board end metal cover body 1331, so that the first and second board end penetration grooves 1311 and 1312 of the board end insulator 131 are exposed, and the line end insulator 121 and the line end shielding conductor rivet portion 1221 of the high-frequency RF jumper 4 can be respectively penetrated from top to bottom into the first and second board end penetration grooves 1311 and 1312, thereby limiting the line end connector 12 in the board end connector 13. In this regard, it is optional, such as Figure 5 to Figure 6In the illustrated embodiment, the line end shielding terminal 122 is also provided with a line end wing plate body 1223, so that the line end wing plate body 1223 is embedded in the board end insulator 131, thereby stopping the line end shielding terminal 122 from moving relative to the board end insulator 131, thereby preventing the line end connector 12 from laterally withdrawing from the board end connector 13, and ensuring that the line end connector 12 is limited in the board end connector 13.
[0041] The board end cover body snap-on structure 1333 can snap-on the board end insulator 131 or the board end shielding terminal 132, so that the board end metal cover body 133 is snap-on to the board end connector 13, and the line end connector 12 can be limited in the board end connector 13 without the engagement between the line end connector 12 and the board end connector 13, so that the overall height of the line end connector 12 and the board end connector 13 used in combination can be greatly reduced compared to the existing RF connection components, so as to meet the demand for thinner mobile communication devices in recent years.
[0042] Accordingly, if Figure 6 In the embodiment shown, the board end insulator 131 and the board end shielding terminal 132 can be respectively provided with a board end insulator buckling structure 1313 and a board end shielding terminal buckling structure 1325 for buckling the board end metal cover 133, such as a bump, so that the board end metal cover 133 is respectively combined with the board end insulator 131 and the board end shielding terminal 132. It should be noted that, if Fig.16 In the illustrated embodiment, when the board-side metal cover 133 is buckled onto the board-side connector 13 , the board-side metal cover body 1331 directly and electrically contacts the board-side shielding terminal 132 and the line-side shielding conductor rivet portion 1221 .
[0043] The circuit substrate 14 includes a substrate core wire contact portion 141 and a substrate shielding loop 142, wherein the substrate core wire contact portion 141 and the substrate shielding loop 142 are electrically isolated from each other, and the substrate shielding loop 142 surrounds the substrate core wire contact portion 141, thereby providing a shielding environment for the substrate core wire contact portion 141. It should be noted that the line end connector 12 of the present invention is arranged in the first board end penetration groove 1311, so that the cable center conductor end contact portion 1112 extends toward the direction of the substrate core wire contact portion 141, and passes through the first board end penetration groove 1311 without passing through other conductors to directly electrically contact the substrate core wire contact portion 141. The board end shielding terminal 132 has a board end solder foot 1324 and directly electrically contacts the substrate shielding loop 142.
[0044] For the high frequency RF connection component of the present invention, such as Figure 5 As shown, the plate end metal cover body 1331 is in a lifted state, so that the cable center conductor end contact portion 1112 and the line end shield conductor riveting portion 1221 can be respectively inserted into the first and second plate end insertion grooves 1311 and 1312. Fig. 9 , Fig.12 As shown, the board end metal cover 133 can be buckled with the board end insulator 131 or the board end shielding terminal 132 to limit the high frequency RF jumper 4 of the present invention. Fig.15 As shown, the line end shielding terminal 122 is electrically connected to the board end shielding terminal 132, the board end metal cover body 1331 and the substrate shielding loop 142, respectively, to form a shielding environment surrounding the first board end through-groove 1311 (the shielding environment is Fig.15 The first board end through-hole 1311 is electrically shielded to form a complete shielding structure similar to a coaxial cable, thereby preventing electromagnetic coupling interference from occurring in the first board end through-hole 1311 when the contact portion 1112 at the end of the cable center conductor transmits a high-frequency RF signal.
[0045] Furthermore, if Fig.16 As shown, the line end shield conductor riveting portion 1221 of the line end connector 12 is electrically in contact with the second board end shielding body 1322, so that the second board end shielding body 1322 is electrically connected to the line end shield conductor riveting portion 1221, and a shielding environment is formed at the connecting portion of the first and second board end through grooves 1311 and 1312 (the shielding environment is Fig.16 The first board end through-hole 1311 is electrically shielded to prevent electromagnetic coupling interference from occurring in the first board end through-hole 1311 when the cable center conductor end contact portion 1112 transmits a high-frequency RF signal.
[0046] Also, please see Figure 20 to Figure 21 The plate end metal cover 133 of the present invention further includes an elastic structure 1334, which can be Fig. 20 Wire springs shown or Fig.21 In the embodiment of the present invention, the elastic structure 1334 of the board end metal cover 133 is located between the board end metal cover body 1331 and the board end shielding terminal 132, so that when the board end cover body buckling structure 1333 buckles the board end insulator 131 or the board end shielding terminal 132, the board end metal cover body 1331 is electrically contacted with the line end shielding terminal 122 to ensure that a shielding environment is formed in the first board end through-groove 1311, and also provides elastic force to force the cable center conductor end contact portion 1112 to electrically contact with the substrate core wire contact portion 141, so as to ensure that the cable center conductor end contact portion 1112 can transmit the high-frequency RF signal to the substrate core wire contact portion 141.
[0047] For the transmission effect of the present invention on high frequency RF signals, please refer to Fig.19The S11 parameter simulation diagram of the present invention for transmitting high-frequency RF signals. Generally speaking, the S11 parameter value represents the return loss, that is, how much energy is reflected back to the source end. The smaller the S11 parameter value, the better. The current industry standard for the S11 parameter value of high-frequency signals transmitting in the 67GHz frequency band is -10dB. In this regard, according to Fig.19 It can be seen from the disclosure that when the present invention transmits high-frequency RF signals in the 100 GHz band, the S11 parameter value has even reached an excellent performance of less than -20dB. That is, the present invention can control the S11 parameter value below -20dB when transmitting high-frequency RF signals in the 100 GHz band. Therefore, the present invention can effectively avoid electromagnetic coupling interference in the transmission of high-frequency RF signals and has excellent high-frequency RF signal transmission effects.
[0048] In summary, the high-frequency RF connection component and its high-frequency RF jumper and board-end connector of the present invention mainly omit the center terminal of the line-end connector and the board-end connector, and directly electrically contact the end of the cable center conductor of the coaxial cable with the circuit substrate without passing through other conductors, and directly transmit the high-frequency RF signal from the cable center conductor of the coaxial cable to the circuit substrate, and design the structure of the high-frequency RF connection component to provide a complete shielding environment for the transmission of high-frequency RF signals, and avoid electromagnetic coupling interference and attenuation of high-frequency RF signals during transmission, and can even be used for the transmission of high-frequency RF signals in the 67 GHz band and above. Furthermore, the board-end connector of the high-frequency RF connection component of the present invention limits the line-end connector through the board-end metal cover, so that the overall height of the board-end connector and the line-end connector used in combination can be greatly reduced compared with the existing RF connection component, in order to meet the demand for thin RF connection components.
[0049] The above-mentioned embodiments only express several implementation methods of the present invention, and the description thereof is relatively specific and detailed, but it cannot be understood as limiting the scope of the patent of the present invention. It should be pointed out that, for ordinary technicians in this field, several variations and improvements can be made without departing from the concept of the present invention, which all belong to the protection scope of the present invention. Therefore, the protection scope of the patent of the present invention shall be subject to the attached claims.
