Description

Technical Field

[0001] The present invention belongs to the technical field of radio frequency connectors, and in particular relates to a radio frequency sub-connector, a radio frequency connector and a radio frequency connector assembly suitable for high-density radio frequency signal transmission in a confined space. Background Art

[0002] See also Figure 1 At present, the transmission of RF signals between boards mainly relies on RF cables 50 in conjunction with RF contacts 40 fixed on the inter-board connector 30. However, with the development of equipment, the space inside the chassis is getting smaller and smaller. When high-density RF signals need to be transmitted, the number of RF contacts is usually increased. When the number of RF contacts is increased, the multiple RF cables connected to multiple RF contacts are not only troublesome to wire, but also there is no extra space for placing cables inside the chassis. Even if multiple RF contacts are directly welded on the printed circuit board in an array distribution, the space occupied is still very large, and the corresponding space requirements cannot be provided inside the chassis. Therefore, how to achieve high-density RF signal transmission in a confined space is a technical problem that needs to be solved urgently. Summary of the invention

[0005] With the help of the above-mentioned technical solution, the present invention has the following advantages: the second inner conductor serves as the central node for the transmission of RF signals, and the outer guide tube, the conductive pad and the conductive net serve as the outer conductor for the transmission of RF signals as a whole after being connected, so that the sub-connector adopts a structure in which multiple core RF signals are integrated on a connector shell and a shared outer conductor to realize the transmission of RF signals. This structure is highly integrated, effectively improves the density of RF contacts, is conducive to the miniaturization of connectors, and realizes the transmission of high-density RF signals in confined spaces.

[0006] In one embodiment, the second shell includes a second main body portion 2011, a third wall portion 2012 extending from one side of the second main body portion along the second direction, and a fourth wall portion 2013 extending from the other opposite side of the first main body portion along the second direction. The second main body portion is provided with an adapting mating surface 20111, and a plurality of receiving holes 20112 arranged in multiple rows along the first direction are penetrated on the adapting mating surface, and each outer guide tube 202 is arranged in a corresponding receiving hole.

[0007] In one embodiment, connecting arms 2021 are respectively cantilevered from two sides of the outer guide tube distributed along the first direction, and the connecting arms are forcibly installed in the corresponding receiving holes.

[0008] In one embodiment, an insulating tube 207 extending along the second direction is installed in the receiving hole 20112, and the insulating tube is placed between the plug-in end of the corresponding second inner conductor and the corresponding outer conductor tube.

[0009] The outer guide tube is supported by the insulating tube to prevent the outer sleeve from being deformed when the sub-connector is plugged in.

[0010] In one embodiment, four spacers 2071 distributed along the circumferential direction are provided on the non-plug-in end of the insulating tube, the insulating tube is forcibly installed into the corresponding receiving hole through the four spacers, and the outer guide tube pin 2022 is forcibly installed into the corresponding insertion hole 2072 between two adjacent spacers.

[0011] In one embodiment, the non-plug-in end of the insulating tube and the inner wall of the receiving hole form a step hole 20113, and the second insulator 204 near the plug-in end is provided with a second step portion 2041 adapted to the aforementioned step hole to force the second insulator into the corresponding receiving hole.

[0012] In one embodiment, the conductive pad is penetrated by a plurality of second terminal avoidance holes 2051 arranged in multiple rows along a first direction, and a second pin socket 2052 is respectively arranged on both sides of the second terminal avoidance holes distributed along a third direction; the plate-connecting end of the second inner conductor passes through the corresponding second terminal avoidance hole, and the outer conductor pin is forcibly installed into the corresponding second pin socket.

[0014] The end of the connecting arm is inserted into the second terminal avoidance hole, which increases the contact and conduction portion between the outer guide tube and the conductive pad and improves the assembly strength of the conductive pad on the second housing.

[0015] In one embodiment, a second mounting groove 2015 for placing a conductive pad is provided on a side of the second body portion 2011 away from the matching mating surface.

[0016] The second mounting groove can reduce the size of the second sub-connector in the second direction, which is beneficial to the miniaturization of the connector.

[0017] In one embodiment, one of the anti-error block 2016 and the anti-error groove 208 is disposed on the inner wall surface of the second installation groove 2015 , and the other is disposed on the conductive pad 205 and the conductive mesh 206 .

[0018] The cooperation between the anti-error block and the anti-error groove facilitates efficient installation of the conductive pad and the conductive mesh on the second shell.

[0019] In order to achieve the above-mentioned purpose, the present invention also adopts a technical solution: a radio frequency connector, including a first sub-connector 10 and a second sub-connector 20 adapted to each other, the second sub-connector adopts the sub-connector in any of the above-mentioned embodiments, the first sub-connector includes a plurality of radio frequency signal transmission chips 101 installed in parallel on a first shell 102 along a first direction, the radio frequency signal transmission chip includes an outer conductor base 1011, an outer conductor cover plate 1012, and a plurality of first inner conductors 1013, the first inner conductor is provided with a plurality of first insulators 1014 distributed along its axial direction, and the plurality of first inner conductors are arranged in parallel on the outer conductor base and the outer conductor cover through corresponding first insulators. In the outer conductor formed by the board connection, the plug-in ends 10131 of the first inner conductors are arranged along the third direction, and the board-connected ends 10132 thereof are arranged along the second direction or the third direction. An outer conductor pin connected to the outer conductor is respectively arranged on both sides of the board-connected ends of the first inner conductors along the arrangement direction thereof. The board-connected end and the outer conductor pin of the first inner conductor both pass through the conductive positioning plate 103, and the outer conductor pin is connected and conducted with the conductive positioning plate. When the first sub-connector and the second sub-connector are plugged in, the plug-in end 10131 of the first inner conductor is connected and conducted with the plug-in end 2031 of the second inner conductor, and the outer guide tube 202 is connected and conducted with the outer conductor covering the plug-in end of the first inner conductor.

[0020] With the aid of the above technical solution, the present invention has the following advantages:

[0021] (1) The RF signal transmission chip has multiple first inner conductors arranged in parallel inside an outer conductor formed by connecting a cover plate and a base. This form of architecture uses an outer conductor to fully surround and shield multiple first inner conductors at the same time, which helps to increase the node density of the RF signal transmission channel and reduce the size of the RF connector, thereby realizing the transmission of high-density RF signals in a confined space;

[0022] (2) A plurality of radio frequency signal transmission chips are installed in parallel on the first housing, and the outer conductors of the plurality of radio frequency signal transmission chips are contacted and connected with the aid of a conductive positioning plate, thereby integrating high-density distributed radio frequency signal transmission channels on a connector housing, which is conducive to the transmission of high-density radio frequency signals in a confined space;

[0023] (3) The second inner conductor serves as the central node for RF signal transmission. After the outer conductor tube, the conductive pad and the conductive net are connected, they serve as the outer conductor for RF signal transmission as a whole. The second sub-connector adopts a structure in which multiple core RF signals are integrated on a connector shell and share the outer conductor to realize RF signal transmission. This structure is highly integrated, effectively improves the density of RF contacts, facilitates the miniaturization of connectors, and realizes the transmission of high-density RF signals in confined spaces.

[0024] In one embodiment, a plurality of mounting grooves 10111 with parallel axes are provided inside the outer conductor base 1011, and a plurality of limiting portions 10112 spaced apart along the axial direction are provided on the mounting grooves. After the first inner conductor is installed in the corresponding mounting groove and the first insulator is inserted into the corresponding limiting portion, the outer conductor cover plate 1012 is connected to the outer conductor base 1011 to form an outer conductor.

[0025] The present application can firmly assemble the first inner conductor in the outer conductor through the snap-fitting cooperation between the first insulator and the limiting portion. Meanwhile, both the outer conductor base and the outer conductor cover can be manufactured by utilizing the existing plastic electroplating process, which can greatly reduce the connector cost.

[0026] In one embodiment, the plug-in end of the first inner conductor does not protrude from the outer conductor base and the outer conductor cover plate, and a plurality of walls 101121 distributed along a third direction are provided on the outer conductor base 1011 covering the plug-in end of the first inner conductor, and the plug-in end and the walls of the first inner conductor are staggered in the third direction; a plurality of third outer conductor pins 101120 are protruded from the outer conductor base or the outer conductor cover plate located on the side where the first inner conductor plate connection end is located, and a third outer conductor pin is respectively provided on both sides of the first inner conductor plate connection end along its arrangement direction.

[0027] After the outer conductor cover is connected to the outer conductor base, the wall and the outer conductor cover are in contact and conduction, so that the plug-in ends of the first inner conductors are respectively located in independent fully enclosed shielding cavities formed by the outer conductor base, the wall, and the outer conductor cover, and the outer conductor pins are extended from the outer conductor cover or the outer conductor base, so that stable transmission of radio frequency signals can be guaranteed without additional parts, which is conducive to reducing connector costs.

[0028] In one embodiment, the plug-in end of the first inner conductor protrudes from the outer conductor base and the outer conductor cover plate, and the outer conductor also includes a first shielding plate 1015 connected to the outer side of the outer conductor base, and a second shielding plate 1016 connected to the outer side of the outer conductor cover plate, the first shielding plate has a first extension area 10154 protruding from the outer conductor base and used to cover the plug-in end of the first inner conductor, the second shielding plate has a second extension area 10164 protruding from the outer conductor cover plate and used to cover the plug-in end of the first inner conductor, the first extension area and the second extension area are connected and conducted through a plurality of shielding contacts 1017 distributed along a third direction, and the plug-in end of the first inner conductor and the shielding contacts are staggered in the third direction.

[0029] After the outer conductor base is connected to the outer conductor cover plate, the plug-in end of the first inner conductor protrudes from the outer conductor. After the two shielding plates are respectively connected to the outer conductor base and the outer conductor cover plate, the plug-in end of the first inner conductor protruding from the outer conductor is located in a fully enclosed shielding cavity formed by the first extension area, the shielding contact piece, and the second extension area, and the shielding effect is better. In addition, the first shielding plate, the second shielding plate, and the shielding contact piece can all be manufactured using molds, which is conducive to later mass production.

[0030] In one embodiment, third extension zones 10155 for connecting and conducting with the second extension zone are arranged on both sides of the first extension zone distributed along the third direction, or third extension zones 10155 for connecting and conducting with the first extension zone are arranged on both sides of the second extension zone distributed along the third direction, and the mating ends of the two outermost first inner conductors in the third direction are located between the shielding contact and the third extension zone.

[0031] By respectively arranging the third extension zone on both sides of the first extension zone or the second extension zone distributed along the third direction, the plug-in ends of the two outermost first inner conductors are located in a fully enclosed shielding cavity formed by the first extension zone, the second extension zone, the third extension zone and the shielding contact piece, and the plug-in ends of the remaining first inner conductors are placed in a shielding contact cavity formed by the first extension zone, the second extension zone and two adjacent shielding contacts, thereby reducing the number of shielding contacts used.

[0032] In one embodiment, the shielding contact 1017 includes two cantilevers 10171 symmetrically distributed along the third direction, one end of the two cantilevers is connected by a bridging arm 10172, and the other end of the cantilever is connected to the outer conductor base 1011 near the first inner conductor plug-in end 10131.

[0033] The present application arranges a plurality of shielding contacts at intervals in a third direction perpendicular to the plug-in direction (i.e., the second direction). The structural feature of the two symmetrically distributed cantilevers causes the plug-in end of the chip to occupy a larger length. By increasing the distance between the two cantilevers, the distance between the two first inner conductor plug-in ends on both sides of the shielding contact on the same chip is also increased, which is of great significance for reducing signal crosstalk.

[0034] In one embodiment, a plurality of slots 101113 distributed along a third direction are provided on the outer conductor base 1011 near the first inner conductor plug-in end, and the other end of the cantilever 10171 is placed in the corresponding slot.

[0035] The assembly efficiency of the product can be improved by the snap-fitting between the other end of the cantilever and the snap-fitting groove.

[0036] In one embodiment, a recess 101712 is provided on the other end of the cantilever to form a protrusion 101713 on the other end of the cantilever; a plurality of first clamping holes 101115 connected with the corresponding clamping slot are provided along a third direction on the outer conductor base 1011 near the first inner conductor plug-in end, and a plurality of second clamping holes 10123 are provided along a third direction on the outer conductor cover plate 1012 near the first inner conductor plug-in end; when the other end of the cantilever is placed in the corresponding clamping slot, a plurality of protrusions on the same side enter into the corresponding first clamping holes, and a plurality of protrusions on the opposite side enter into the corresponding second clamping holes; the outer conductor base located on one side of the first clamping hole and the outer conductor cover plate located on one side of the second clamping hole are respectively clamped into the recesses on the corresponding sides.

[0037] The present application uses the cooperation of the recess, protrusion and card hole to make the other end of the cantilever engage with the outer conductor base and the outer conductor cover plate, so that the shielding contact and the outer conductor assembly form a blocking fit in the plugging and unplugging direction, thereby improving the installation stability and shielding conduction capability of the shielding contact.

[0038] In one embodiment, two adjacent slots 101113 form a slot group, a first inner conductor 1013 is distributed between the two adjacent slot groups, and a support block 101114 for inserting between two cantilevers is protruded from the outer conductor base 1011 between the two slots in the same slot group.

[0039] The other ends of the two cantilevers cooperate with the two slots at two locations to further improve the installation stability of the shielding contact piece. Meanwhile, a support block is inserted between the two cantilevers to increase the overall strength of the shielding contact piece.

[0040] In one embodiment, the other end of the cantilever is open so that the shielding contact piece is U-shaped.

[0041] The present application can conveniently control the distance between the two cantilevers by means of the U-shaped structure, thereby controlling the spacing between the two adjacent first inner conductor plug-in ends.

[0042] In one embodiment, the first shell includes a first main body portion 1021, a first wall portion 1022 extending from one side of the first main body portion along the second direction, and a second wall portion 1023 extending from the other opposite side of the first main body portion along the second direction. A plurality of plug-in end receiving grooves 10212 arranged in multiple rows along the first direction are penetrated through the first main body portion, a plurality of first slots 10221 distributed along the first direction are provided on the first wall portion, a plurality of second slots distributed along the first direction are provided on the second wall portion, and the first slot 10221, the second slot 10231, and the plurality of plug-in end receiving grooves 10212 on the same row aligned with each other along the third direction are used together to accommodate a radio frequency signal transmission chip 101.

[0043] In one embodiment, a plurality of connecting walls 1024 extending along a third direction are spaced apart along the first direction between the first wall portion 1022 and the second wall portion 1023, and a row of plug-in end receiving grooves are distributed between two adjacent connecting walls. The first slot, the second slot, the plurality of plug-in end receiving grooves on the same row aligned with each other along the third direction, and the connecting walls are used together to receive a radio frequency signal transmission chip.

[0044] The close contact between the first extension area, the second extension area and the connecting wall on the same side ensures that the assembled radio frequency signal transmission chip will not shake.

[0045] In one embodiment, a plurality of first guide keys 10223 distributed along the first direction are provided on the first wall portion 1022, a plurality of second guide keys 10234 distributed along the first direction are provided on the second wall portion 1023, and a shape of at least one first guide key is different from that of the second guide key; a plurality of first key grooves 20121 matched with the first guide keys are provided on the third wall portion 2012 along the first direction, and a plurality of second key grooves 20131 matched with the second guide keys are provided on the fourth wall portion 2013 along the first direction.

[0046] By means of the cooperation between the first guide key and the first key slot, and the cooperation between the second guide key and the second key slot, the two sub-connectors can be smoothly plugged in and the wrong plugging phenomenon can be avoided.

[0047] In one embodiment, the shielding contact 1017 includes two cantilevers 10171 symmetrically distributed along the third direction, one end of the two cantilevers is connected by a bridging arm 10172, and the other end of the cantilever is connected to the outer conductor base 1011 near the first inner conductor plug-in end 10131; a groove 101713 is provided on one of the bridging arm 10172 and the first main body 1021 facing away from the mating surface, and a protrusion 10213 for limiting cooperation with the aforementioned groove is provided on the other.

[0048] The present application achieves front end positioning of the shielding contact when two sub-connectors are in a mutually plugged state through the limiting cooperation of the protrusion and the groove, thereby preventing the front end of the shielding contact from swinging or tilting and improving the shielding stability.

[0049] In one embodiment, a first outer conductor pin 10152 connected to the first shielding sheet and a second outer conductor pin 10162 connected to the second shielding sheet are respectively provided on both sides of the first inner conductor plate terminal along its arrangement direction.

[0050] Since the two shielding sheets adopt a sheet structure, it is convenient to process the first outer conductor pin and the second outer conductor pin, so that the board connection end of the RF signal transmission chip forms a signal arrangement form of GSGGSGGSG, reducing the interference between the inner conductors during RF signal transmission.

[0051] In one embodiment, limiting grooves 10119 are provided on the outer conductor base 1011 located on both sides of the first inner conductor plate terminal, the first outer conductor pin 10152 has a first supporting portion 10153 for connecting to the first shielding plate 1015, and the second outer conductor pin 10162 has a second supporting portion 10163 for connecting to the second shielding plate 1016, and when the first shielding plate is connected to the outer side of the outer conductor base, the first supporting portion enters the limiting groove on one side of the first inner conductor plate terminal, and when the second shielding plate is connected to the outer side of the outer conductor cover plate, the second supporting portion enters the limiting groove on the other side of the first inner conductor plate terminal.

[0052] Through the cooperation of the first supporting portion, the second supporting portion and the limiting groove, the two outer conductor pins are stably placed on both sides of the first inner conductor plate terminal along its arrangement direction.

[0053] In one embodiment, the outer conductor base 1011 forms a first mounting surface 10114 perpendicular to the first direction and a second mounting surface 10115 higher than the first mounting surface through steps, the outer conductor cover plate 1012 is connected to the first mounting surface, and the second shielding sheet 1016 is connected to the second mounting surface.

[0054] By designing the first mounting surface and the second mounting surface, the thickness of the radio frequency signal transmission chip can be reduced, which is beneficial to the miniaturization of the connector.

[0055] In one embodiment, the plug-in ends of a plurality of first inner conductors are arranged along a third direction, and the board-connecting ends thereof are arranged along a second direction; a first baffle 101116 is provided on the side of the outer conductor base facing away from the plug-in end and protrudes from the first shielding plate and the second shielding plate in the first direction; a second baffle 101117 is provided on the side of the outer conductor base facing away from the board-connecting end and protrudes from the first shielding plate and the second shielding plate in the first direction; the first baffle and the second baffle on two adjacent RF signal transmission chips both form a stopping state in the first direction, and the second baffle 101117 forms a stopping state with the second wall portion 1023.

[0056] When a number of radio frequency signal transmission chips are mounted in parallel on the shell of the sub-connector, the first stop bar and the second stop bar on two adjacent chips both form a blocking state in the first direction to prevent the chips from swinging when subjected to external force; at the same time, the second stop bar cooperates with the shell of the sub-connector to prevent the chips from being inserted too far during assembly; in addition, the first inner conductor is distributed in a curved manner, and the sub-connector equipped with the first inner conductor is suitable for signal transmission between two mutually perpendicular printed circuit boards.

[0057] In one embodiment, a first locking block 101161 and a second locking block 101162 are respectively provided on both sides of the outer conductor base near the first inner conductor plug-in end distributed along the third direction, a first locking hole 10222 for lockingly fitting with the first locking block is penetrated in the first slot 10221, and a second locking hole 10232 for lockingly fitting with the second locking block is penetrated in the second slot 10231.

[0058] The locking fit between the locking block and the locking hole prevents the assembled radio frequency signal transmission chip from being separated from the housing of the sub-connector.

[0059] In one embodiment, the conductive positioning plate 103 is penetrated by a plurality of first terminal avoidance holes 1031 arranged in multiple rows along a first direction, and a first pin socket 1032 is respectively arranged on both sides of the first terminal avoidance holes distributed along a second direction or a third direction; the plate connection end of the first inner conductor passes through the corresponding first terminal avoidance hole, and the outer conductor pin is forcibly installed into the corresponding first pin socket.

[0060] In one embodiment, a plurality of inserting strips 1035 are arranged along a first direction on the wall surface of the conductive positioning plate facing the connection end of the first inner conductor plate, and a plurality of first terminal avoidance holes and a plurality of first pin plug holes distributed in the same row are arranged between two adjacent inserting strips; the inserting strips are inserted between two adjacent RF signal transmission chips.

[0061] By means of the blocking bar inserted between the two wafers, the overall strength of the first sub-connector is improved.

[0062] In one embodiment, a plurality of clamping blocks 1033 are arranged along the first direction on the wall surface of the conductive positioning plate facing the plate connection end, a plurality of third clamping holes 1034 distributed along the first direction are arranged through the conductive positioning plate, and a clamping block is arranged on one side of a plurality of first terminal avoidance holes and a plurality of first pin plug holes distributed in the same row, and a third clamping hole is arranged on the other opposite side, and a limiting step 101118 matched with the corresponding clamping block and a third locking block 101119 matched with the corresponding third clamping hole are provided on the outer conductor base 1011.

[0063] By means of the locking cooperation of the clamping block and the limiting step, the third clamping hole and the third locking block, the conductive positioning plate is firmly assembled on the board connection end of the radio frequency signal transmission chip.

[0064] In one embodiment, the first inner conductors 1013 on two adjacent RF signal transmission chips are staggered so that the board connection end 10132 of the first inner conductor on one RF signal transmission chip is located between the outer conductor pin on the adjacent RF signal transmission chip and the outer conductor pin on another adjacent RF signal transmission chip in the first direction; the two adjacent rows of outer guide tubes 202 are staggered.

[0065] The advantages of such a design are as follows: (1) by staggeredly loading two types of RF signal transmission chips onto the first shell along the first direction, the plate-connected end of the first inner conductor is located between the outer conductor pin on the adjacent RF signal transmission chip and the outer conductor pin on another adjacent RF signal transmission chip in the first direction. At the same time, since the plate-connected end of the first inner conductor is located between the two outer conductor pins on the same RF signal transmission chip in its arrangement direction (i.e., the second direction or the third direction), the plate-connected end of the first inner conductor, which is a RF signal transmission node, is completely surrounded by the outer conductor pin in the circumferential direction, which can increase the number of reference grounds surrounding the RF signal transmission node in the circumferential direction, and has excellent shielding performance and strong anti-crosstalk capability; (2) the plate-connected end of the second inner conductor is located between the outer conductor pin of the adjacent outer conductor and the outer conductor pin of another adjacent outer conductor in the first direction, and the plate-connected end of the second inner conductor is located between the two outer conductor pins of the corresponding outer conductor in the third direction, that is, the plate-connected end of the second inner conductor, which is a RF signal transmission node, is completely surrounded by the outer conductor pin in the circumferential direction, which can increase the number of reference grounds surrounding the RF signal transmission node in the circumferential direction, and has excellent shielding performance and strong anti-crosstalk capability.

[0066] In one embodiment, the second sub-connector also includes a conductive mesh 206 connected to the outside of the conductive pad, the board connection end 2032 of the second inner conductor and the outer conductor pin 2022 both pass through the conductive mesh, and fourth spring sheets 2062 connected to the conductive mesh are arranged on both sides of the board connection end of the second inner conductor distributed along the first direction, and the fourth spring sheets are tilted in the direction away from the conductive pad.

[0067] The advantages of this design are: (1) the plate-connected end of the second inner conductor is located between the two outer conductor pins in the third direction and between the two fourth spring sheets in the first direction, that is, the plate-connected end of the second inner conductor is surrounded by the outer conductor pins and the fourth spring sheets in the circumferential direction. Since the distance between the plate-connected end of the second inner conductor and the fourth spring sheet is smaller than the distance between the plate-connected end of the second inner conductor and the outer conductor pin of the adjacent outer conductor, the shielding effect is better, thereby improving the signal transmission capability and reducing signal crosstalk; (2) with the help of the fourth spring sheet tilted away from the conductive pad, the contact and conduction between the outer conductor and the second printed circuit board are facilitated.

[0068] In order to achieve the aforementioned purpose, the technical solution adopted by the present invention is: a radio frequency connector assembly, including the radio frequency connector in any of the aforementioned embodiments, the board connection terminal 10132 of the first inner conductor and the outer conductor pin on the first sub-connector are connected to the first printed circuit board, and the board connection terminal 2032 of the second inner conductor and the outer conductor pin 2022 on the second sub-connector are connected to the second printed circuit board.

[0108] See also Figure 2 and Figure 3 , discloses an embodiment of a radio frequency connector of the present invention. For the convenience of explanation, this embodiment defines the arrangement direction of a plurality of radio frequency signal transmission chips as the "first direction", the plug-in and unplugging direction of two sub-connectors as the "second direction", and the direction perpendicular to both the first direction and the second direction as the "third direction". In this embodiment, the radio frequency connector includes a first sub-connector 10 and a second sub-connector 20 adapted to the first sub-connector. The first sub-connector is used to connect with the first printed circuit board, and the second sub-connector is used to connect with the second printed circuit board. After the first sub-connector and the second sub-connector are plugged in place, the first printed circuit board and the second printed circuit board are in a vertical state. In this embodiment, the first sub-connector 10 is a plug, and the second sub-connector 20 is a socket.

[0109] See also Figure 4 The first sub-connector 10 includes a plurality of RF signal transmission chips 101 mounted in parallel on a first shell 102 along a first direction, and a conductive positioning plate 103 arranged on the board connection end of the RF signal transmission chip (i.e., the end of the RF signal transmission chip used to connect to the first printed circuit board).

[0110] See also Figure 5 and Figure 6 The RF signal transmission chip 101 includes an outer conductor base 1011 and an outer conductor cover 1012 connected as one body, a plurality of first inner conductors 1013 distributed in parallel in the outer conductor base through a first insulator 1014, a first shielding sheet 1015 connected to the outer side of the outer conductor base, and a second shielding sheet 1016 connected to the outer side of the outer conductor cover.

[0111] See also Figure 7 and Figure 8The outer conductor base 1011 is made of conductive material (for example, plastic electroplating process, that is, plastic injection molding is used to form the outer conductor base substrate, and the surface of the substrate is electroplated with conductive metal to form a complex and low-cost outer conductor base 1011), and a plurality of mounting grooves 10111 with parallel axes are arranged inside, and each mounting groove is distributed in a curved manner (that is, the axis of the first port 101111 of the mounting groove and the axis of the second port 101112 are vertical), and a plurality of limiting portions 10112 are arranged along the axial direction of the mounting groove; the outer conductor base 10111 located between two adjacent mounting grooves is provided with a plurality of stoppers 10112; A plurality of blind holes 10113 are provided on the conductor base 1011, which can reduce the weight of the outer conductor on the one hand, and reduce the signal crosstalk phenomenon after the inner conductor is placed in the mounting groove on the other hand; the outer conductor base 1011 forms a first mounting surface 10114 and a second mounting surface 10115 perpendicular to the first direction through steps, and the first mounting surface 10114 is lower than the second mounting surface 10115; a first locking block 101161 and a second locking block 101162 are respectively provided on both sides of the outer conductor base distributed along the third direction near the first port, and the locking blocks are used to be locked with the corresponding locking holes on the first shell.

[0112] See also Fig. 9 The first inner conductor 1013 is made of metal material, and its axis is consistent with the axis of the installation groove 10111. The first insulator 1014 is made of plastic, and its shape is compatible with the shape of the limiting portion 10112. The insert injection molding process is used to obtain Fig. 9 The signal contact structure shown in the figure is as follows: a plurality of first insulators are arranged on the first inner conductor along the axial direction thereof at intervals. During assembly, the first inner conductor is placed in the mounting groove through the snap-fitting of the first insulator and the stopper, and the two are arranged coaxially. At this time, the plug-in end 10131 and the board connection end 10132 (i.e., the end of the first inner conductor for connecting to the first printed circuit board) of the first inner conductor are both protruded from the outer conductor base 1011 (such as Fig.10 As shown). Further, in order to make the plug-in end 10131 and the board connection end 10132 of the first inner conductor have greater strength, a first insulator 1014 close to the plug-in end is assembled in the first port 101111 of the mounting groove, and a first insulator 1014 close to the board connection end is assembled in the second port 101112 of the mounting groove. Further, in this embodiment, the board connection end of the first inner conductor adopts a fisheye terminal structure, which is connected to the first printed circuit board by solder-free crimping.

[0113] Please also see Figure 7 , Figure 8 and Fig.11A plurality of first positioning posts 10117 are arranged on one side of the outer conductor base 1011 distributed along the first direction, and the outer conductor cover plate 1012 is also made of a conductive material (e.g., a plastic electroplating process), and a plurality of first limiting holes 10121 corresponding to the first positioning posts are arranged on the outer conductor cover plate (of course, in other embodiments of the present invention, the positions of the positioning posts and the limiting holes can be swapped), after the first inner conductor and the first insulator are assembled in the mounting groove, the outer conductor cover plate is buckled on the outer conductor by the first positioning posts and the first limiting holes. On the base, the first inner conductor located between the plug-in end and the board connection end is placed in the installation cavity inside the outer conductor composed of the outer conductor base and the outer conductor cover plate, so as to realize that one outer conductor fully surrounds and shields several first inner conductors at the same time. With this form of architecture, several inner conductors of different sizes can be set in a chip, and a cover plate and a base can be used to form an outer conductor that fully surrounds and shields multiple inner conductors at the same time, which helps to increase the node density of the radio frequency signal transmission channel and is conducive to reducing the size of the connector, thereby realizing the transmission of high-density radio frequency signals in a confined space. Further, the several first inner conductors 1013 assembled in the installation groove are coplanarly distributed. Further, after being assembled in place, the outer conductor cover plate 1012 is placed on the first mounting surface 10114 of the outer conductor base and is flush with the second mounting surface 10115, thereby reducing the size of the chip in the thickness direction. Furthermore, a plurality of first avoidance holes 10122 are arranged at intervals on one side of the outer conductor cover plate 1012 corresponding to the side where the second port 101112 is located. After being assembled, the outer conductor bases on both sides of the second port are respectively placed in the corresponding first avoidance holes. With the help of the first avoidance holes, not only can the outer conductor cover plate be efficiently fastened on the outer conductor base to avoid mis-assembly, but also the overall strength of the outer conductor can be improved.

[0114] See also Figure 7 , Figure 8 The outer conductor base 1011 is provided with a plurality of first positioning posts 10117 on one side distributed along the first direction, and a plurality of second positioning posts 10118 on the other opposite side distributed along the first direction, see Fig.12 and Fig.13The first shielding sheet 1015 and the second shielding sheet 1016 are both made of metal materials and the first shielding sheet is provided with a plurality of second limiting holes 10151 corresponding to the aforementioned second positioning column 10118, and the second shielding sheet is provided with a plurality of third limiting holes 10161 corresponding to the aforementioned first positioning column 10117. In this embodiment, the second limiting holes and the third limiting holes are both plum blossom-shaped. In addition, a plurality of first outer conductor pins 10152 distributed along the second direction are protruded on the first shielding sheet corresponding to the side where the second port is located, and a plurality of second outer conductor pins 10162 distributed along the second direction are protruded on the second shielding sheet corresponding to the side where the second port is located. In this embodiment, the edge portion of the first shielding sheet corresponding to the second port is cut and bent to serve as the first support portion 10153 of the corresponding first outer conductor pin, and the edge portion of the second shielding sheet corresponding to the side of the second port is cut and bent (in the opposite direction of the bending direction when the support portion of the first outer conductor pin is formed) to serve as the second support portion 10163 of the corresponding second outer conductor pin, and the first outer conductor pin and the second outer conductor pin both adopt a fisheye terminal structure. Please refer to Figure 8 , the outer conductor base 1011 located on both sides of the second port is provided with a limiting groove 10119, after the first inner conductor is placed inside the outer conductor composed of the outer conductor base and the outer conductor cover plate, the plate connection ends of the first inner conductors are all protruding from the outer conductor base, and the first shielding sheet 1015 is assembled on the outer side of the outer conductor base 1011 through the second limiting hole and the second positioning column, and the first supporting portion 10153 of the first outer conductor pin 10152 enters the limiting groove 10119 on one side of the second port at the same time, and the first inner conductor is placed in the outer conductor base 1011 through the third limiting hole and the first positioning column. The second shielding sheet 1016 is assembled on the outer side of the outer conductor cover plate 1012 by the strong fit of the positioning column, and the second supporting portion 10163 of the second outer conductor pin 10162 enters the limiting groove 10119 on the other side of the second port at the same time, so that each of the two sides of the board connection end 10132 of the first inner conductor has an independent first outer conductor pin 10152 and a second outer conductor pin 10162, so that the end of the radio frequency signal transmission chip used for connecting to the first printed circuit board is arranged in a GSGGSGGSG manner along the second direction (such as Fig.14 As shown, S represents the plate connection end of the first inner conductor, which is used as a radio frequency signal transmission node, and G represents the outer conductor pins on the two shielding sheets that are connected to the outer conductor, which are used for grounding and shielding), reducing the interference between the inner conductors during radio frequency signal transmission. Further, after being assembled in place, the second shielding sheet 1016 is placed on the second mounting surface 10115 of the outer conductor base, further reducing the size of the chip in the thickness direction.

[0115] The outer conductor also includes a first shielding sheet and a second shielding sheet. Fig.12The first shielding sheet 1015 has a first extension area 10154 protruding from the outer conductor base, and the third extension areas 10155 are respectively arranged on both sides of the first extension area distributed along the third direction. In this embodiment, the main body of the first shielding sheet protruding from the outer conductor base is respectively bent on both sides distributed along the third direction to form the third extension area; please refer to Fig.13 , the second shielding sheet 1016 has a second extension area 10164 protruding from the outer conductor cover and in a planar shape; this embodiment also includes a plurality of shielding contacts 1017 spaced apart along the third direction, each shielding contact 1017 cantilevers out along the second direction from a side of the outer conductor base having a first port (i.e., a side close to the first inner conductor plug-in end) and a shielding contact is arranged between two adjacent first ports, after a plurality of first inner conductors are parallelly installed in the outer conductor formed by buckling the base and the cover through the first insulator, the plug-in ends of the plurality of first inner conductors spaced apart along the third direction all protrude from the outer conductor base and are covered by the first extension area and the second extension area, a shielding contact is arranged between the plug-in ends 10131 of the two adjacent first inner conductors Contact 1017, after connecting the first shielding plate to the outside of the outer conductor base and the second shielding plate to the outside of the outer conductor cover, the two third extension areas 10155 are both in contact and conduction with the second extension area 10164, and the shielding contact 1017 is respectively in contact and conduction with the first extension area 10154 and the second extension area 10164, and the plug-in ends of the two first inner conductors located on the outermost side along the third direction are located in a fully enclosed shielding cavity surrounded by the first extension area, the second extension area, the third extension area and the shielding contact, and the plug-in ends of the remaining first inner conductors are all located in the fully enclosed shielding cavity surrounded by the first extension area, the second extension area and the two shielding contacts, so that the plug-in ends of each first inner conductor are in a circumferentially complete fully enclosed shielding cavity, such as Fig.15 shown.

[0116] See also Fig.16 The shielding contact 1017 includes two cantilevers 10171 symmetrically distributed along the third direction. The ends of the two cantilevers away from the outer conductor base are connected by a bridge arm 10172 so that one end of the shielding contact is closed and the other end is open. Two slots 101113 distributed along the third direction are arranged on the outer conductor base between two adjacent first ports. Fig.17, the other ends of the two cantilevers 10171 are respectively placed in the corresponding card slots 101113 so that the shielding contact cantilevers on the side of the outer conductor base having the first port. In this embodiment, a plurality of U-shaped shielding contacts are arranged at intervals in the third direction perpendicular to the plug-in direction (i.e., the second direction). The U-shaped structural feature makes the plug-in end of the chip occupy a larger length. By increasing the distance between the two cantilevers, the distance between the two first inner conductor plug-in ends on both sides of the shielding contact on the same chip is also increased, which is of great significance for reducing signal crosstalk. Further, the bridge arm 10172 is provided with a groove 101721 for matching with the convex part on the first shell. Further, the outer wall surface of the other end of the two cantilevers is respectively provided with a convex point structure 101711. After the cantilever is placed in the corresponding card slot, the convex point structure ensures the stable contact and conduction between the shielding contact and the outer conductor base. Furthermore, two symmetrically distributed recesses 101712 are provided on the other end of the cantilever, so that two symmetrically distributed protrusions 101713 are formed on the other end of the cantilever, and first clamping holes 101115 connected to the corresponding clamping slot are arranged at intervals along the third direction on the edge side of the outer conductor base close to the first inner conductor plug-in end, and a plurality of second clamping holes 10123 are arranged at intervals along the third direction on the edge side of the outer conductor cover plate close to the first inner conductor plug-in end. After the cantilever is placed in the corresponding clamping slot, a plurality of protrusions on the same side enter into the corresponding first clamping holes, and a plurality of protrusions on the opposite side enter into the corresponding second clamping holes, and the edge side of the outer conductor base on one side of the first clamping hole and the edge side of the outer conductor cover plate on one side of the second clamping hole are respectively inserted into the recesses on the corresponding sides, so that the other end of the cantilever is in a bite state with the outer conductor base and the outer conductor cover plate, so that the shielding contact and the outer conductor assembly form a blocking fit in the plug-in and pull-out direction, thereby improving the installation stability and shielding conduction capability of the shielding contact. Furthermore, two adjacent slots form a slot group, a first inner conductor is distributed between the two adjacent slot groups, and a support block 101114 for inserting between two cantilevers is protruded from the outer conductor base between two adjacent slots in the same slot group. When the shielding contact piece is cantilevered on the side of the outer conductor base having the first port, the support block is located between the two cantilevers, which can increase the overall strength of the shielding contact piece.

[0117] Furthermore, the first extension area 10154 and the third extension area 10155 are respectively provided with a first spring piece 10156 for elastically pressing the corresponding outer guide tube on the second sub-connector to achieve contact and conduction, the second extension area 10164 is provided with a second spring piece 10165 distributed along the third direction and used for elastically pressing the corresponding outer guide tube on the second sub-connector to achieve contact and conduction, and the two cantilevers 10171 of the shielding contact piece are respectively provided with a third spring piece 101714 for elastically pressing the corresponding outer guide tube on the second sub-connector to achieve contact and conduction, thereby ensuring that the four circumferential sides of the outer guide tube entering each fully enclosed shielding cavity are in elastic contact with a spring piece. Specifically, in the present embodiment, the first spring sheet, the second spring sheet, and the third spring sheet all have a fixed end and a free end, and the fixed end is arranged close to the outer conductor base, and the elastic contact formed by the bending is arranged close to the free end. Of course, the present invention does not limit the structural form of the first spring sheet, the second spring sheet, and the third spring sheet, and any existing known spring sheet form can be adopted, for example: the spring sheet has a fixed end and a free end, and the free end is arranged close to the outer conductor base, and the elastic contact formed by the bending is arranged close to the free end; or the spring sheet is in a "7" shape, has two fixed ends, and the bent portion of the spring sheet serves as an elastic contact; or two spring sheets using the aforementioned structural form are a group, and the fixed ends of the two spring sheets in the same group are located on different sides or the same side.

[0118] See also Fig.18 and Fig.19 The first shell 102 is made of insulating material, and includes a first main body portion 1021, a first wall portion 1022 extending from one side of the first main body portion along the second direction, and a second wall portion 1023 extending from the other opposite side of the first main body portion along the second direction. The first main body portion 1021 is provided with a docking surface 10211 and a plurality of plug-in end receiving grooves 10212 penetrating the docking surface. In this embodiment, the plug-in end receiving grooves are arranged in multiple rows along a first direction; the first wall portion 1022 is provided with a plurality of first slots 10221 distributed along the first direction and a plurality of first locking holes 10222 connected to the first slots; the second wall portion 1023 is provided with a plurality of second slots 10231 distributed along the first direction and a plurality of second locking holes 10232 connected to the second slots; the first locking hole 10222 penetrates the first wall portion and is used for locking cooperation with the first locking block 101161 on one side of the RF signal transmission chip; the second locking hole 10232 penetrates the second wall portion and is used for locking cooperation with the second locking block 101162 on the other opposite side of the RF signal transmission chip; the above two locking positions are used to prevent the assembled RF signal transmission chip from detaching from the first shell. The first slot 10221 , the second slot 10231 , and the plurality of plug-in end receiving slots 10212 on the same row aligned with each other along the third direction are used together to receive a radio frequency signal transmission chip 101 .

[0119] In this embodiment, two adjacent rows of plug-in end receiving grooves 10122 on the first housing are staggered. To adapt to this type of first housing, this embodiment uses two types of RF signal transmission chips A and B. The RF signal transmission chip A uses Figure 5 and Figure 6 The structure shown in the figure, the structure of the radio frequency signal transmission chip B is as follows Fig. 20 and Fig.21 The key difference between the RF signal transmission chip B and the RF signal transmission chip A is that the inner conductors on the adjacent RF signal transmission chip A and the inner conductors on the RF signal transmission chip B are staggered (i.e., the inner conductors at corresponding positions on the RF signal transmission chip A and the RF signal transmission chip B are not aligned in the first direction). After the RF signal transmission chips A and the RF signal transmission chips B are staggered along the first direction and installed on the first housing, see Figure 1 and Figure 2 , the plate-connecting ends 10132 of the first inner conductors in two adjacent rows in the first direction are staggered (i.e., the plate-connecting ends of the inner conductors at corresponding positions in the two adjacent rows are offset by a distance X1 in the second direction), so that the plate-connecting ends of the first inner conductors (i.e. Fig. 22 S in the first direction is located at the pin of the shielding sheet on the adjacent RF signal transmission wafer (i.e. Fig. 22 At the same time, since the plate-connected end of the first inner conductor is located between the pins of the two shielding plates on the same RF signal transmission chip in the second direction, that is, the plate-connected end serving as the RF signal transmission node is completely surrounded by the pins of the shielding plate in the circumferential direction, the aforementioned staggered arrangement method enables the pins of the shielding plate to be present around the plate-connected end, thereby increasing the number of reference grounds surrounding the RF signal transmission node in the circumferential direction, and having excellent shielding performance and strong anti-crosstalk capability.

[0120] Furthermore, in order to make it easier to distinguish between the RF signal transmission chips A and B and thus improve assembly efficiency, the first shielding plate on the RF signal transmission chip B in this embodiment removes the third extension area located on both sides of the first extension area. When assembled in place, the first extension area and the second extension area are connected and conducted through a number of shielding contacts distributed along the third direction. The plug-in end of any first inner conductor on the RF signal transmission chip B is located in a fully enclosed shielding cavity formed by the first extension area, the second extension area and the two shielding contacts. Furthermore, a step portion 1018 is recessed on one side of the first extension area and one side of the second extension area near the second locking block 101162 on the RF signal transmission chip B, so that the two extension areas along the third direction do not cover the side of the outer conductor base with the second locking block, which is conducive to intuitively distinguishing the RF signal transmission chips A and B from the appearance. Please also refer to Fig.18 The length of the first slot 10221 and the length of the second slot 10231 for assembling the RF signal transmission chip A are both greater than the length of the adjacent first slot 10221 and the length of the adjacent second slot 10231 for assembling the RF signal transmission chip B.

Furthermore, in order to facilitate the plugging of the two sub-connectors, this embodiment provides an inwardly inclined guide portion 2023 on the plug-in end of the outer guide tube.

[0129] See also Fig.25 and Fig.26 This embodiment further includes an insulating tube 207 extending along the second direction. After the insulating tube 207 is forcibly inserted into the corresponding receiving hole 20112, the insulating tube is placed between the plug-in end of the second inner conductor and the outer guide tube to support the outer guide tube. For details, please refer to Fig.30 In this embodiment, four pads 2071 distributed along the circumferential direction are arranged on the non-plug-in end of the insulating tube 207, and the gap between two adjacent pads is used as a plug hole 2072 for the connecting arm 2021 of the outer guide tube and the outer guide tube pin 2022 to pass through.

All outer conductors are connected and conducted through the conductive pad to serve as the outer conductor for radio frequency signal transmission. Further, in this embodiment, two adjacent rows of second terminal avoidance holes are staggered. Furthermore, the end of the connecting arm 2021 of the outer guide tube is inserted into the corresponding second terminal avoidance hole 2051 (a sixth convex bump 20511 is provided on the contact surface between the end of the connecting arm and the second terminal avoidance hole in this embodiment), which increases the contact and conduction portion between the outer guide tube and the conductive pad on one hand, and improves the assembly strength of the conductive pad on the second shell on the other hand.

With the above-mentioned design, on the board-connected end of the second sub-connector, the board-connected end of the second inner conductor is surrounded by the outer guide tube pins and the fourth spring pieces in all directions in the circumferential direction. Since the distance between the board-connected end of the second inner conductor and the fourth spring piece is smaller than the distance between the board-connected end of the second inner conductor and the outer guide tube pins on the adjacent row, the shielding effect is better, thereby improving the signal transmission capability and reducing the signal crosstalk. Further, in order to make the board-connected end of the second inner conductor have a better shielding effect, two rows of fourth spring pieces are provided between two adjacent rows of second avoidance holes. Furthermore, both sides of the second avoidance hole distributed along the first direction are provided with spring groups, and each spring group includes two symmetrically distributed fourth springs 2062, and the elastic contacts of the two fourth springs are adjacent to each other.
