[0056] The socket connector 20 includes a socket housing 21, a base 22 is installed in the middle cavity of the socket housing 21, the head end of the base 22 extends to the outside of the socket housing 21, and a plurality of pin sills 23 are installed inside the base 22 and are arranged in parallel. In this embodiment, the number of the pin sills 23 is fifty, and a socket cover plate 24 is installed at the tail end opening of the socket housing 21 through a locking cover plate screw B28;

[0057] The pin sill 23 includes a sill body B231, one end of which is provided with a plurality of needle bodies B1 232, and the other end of which is provided with a plurality of needle bodies B2 233. In this embodiment, the needle bodies B1 232 and the needle bodies B2 233 are both provided with eight, and the extension lines of the needle bodies B1 232 and the needle bodies B2 233 are arranged to intersect vertically. The needle bodies B2 233 penetrate the upper end opening of the socket housing 21 and are equipped with a tin block B234.

[0058] The number of needle bodies A-132 and needle bodies B-232 is the same. When the plug connector 10 and the socket connector 20 are plugged in, the base 22 is inserted into the head end of the plug shell 11, and the needle bodies A-132 and the needle bodies B-232 contact to form a transmission channel, and the tin block A134 and the tin block B234 are coplanar.

[0059] The high-speed connector of the coplanar installation form in the present technical solution is composed of a plug connector 10 and a socket connector 20 that can be plugged and connected. The plug connector 10 includes a plug shell 11, a head base 12, and a jack sill 13. The socket connector 20 includes a socket shell 21, a seat base 22, and a pin sill 23.

In the pin sill 23, the extension lines of the needle body B-232 and the needle body B-233 are arranged to intersect vertically, so that the needle body A-132 and the needle body B-232 are in contact to form a transmission channel, and the tin block A134 and the tin block B234 are coplanar, thereby realizing the coplanar installation of the connectors.

[0060] The connector in this technical solution realizes the requirement of coplanar plug-in form while achieving high transmission rate, reduces signal interference loss, has the characteristics of high arrangement density, high density and high transmission rate, and is suitable for use in military equipment architecture systems, and is used for high-speed data transmission of coplanar boards in limited miniaturized military equipment space.

[0061] like Figure 6 , Fig.11 As shown, the needle body A-132 is provided with an arc-shaped portion A-1321 and an arc-shaped portion A-1322, and the needle body B-232 is provided with an arc-shaped portion B2321. The needle body A-132 and the needle body B-232 are formed by stamping, flipping and other processes, and are used for docking the jack sill piece 13 and the pin sill piece 23;

[0062] When the plug connector 10 and the socket connector 20 are plugged in, the needle body A-132 and the needle body B-232 are deformed, and the outer arc surface of the arc portion A-1322 cooperates and elastically contacts with the outer arc surface of the arc portion B2321, which ensures the convenience during plugging. At the same time, the elastic contact and multi-point contact between the needle body A-132 and the needle body B-232 ensure the reliability of signal contact.

[0063] To solve the problem of installing the jack sill 13 inside the head base 12, as Figure 4 , Figure 5 As shown, one side of the head base 12 is set as a mounting groove A121, and the other side extends to form a plurality of partitions A122 that are distributed laterally. In the present embodiment, the number of partitions A122 is set to five, and shielding grooves A125 are set on the opposite end faces of the partitions A122. The number of shielding grooves A125 on each end face is consistent with the number of the jack sill parts 13, and is set to fifty. The side wall of the mounting groove A121 is provided with slot holes A121 whose number is consistent with the number of needle bodies A-132. When the jack sill parts 13 are assembled into the interior of the head base 12, the jack sill parts 13 are located inside the mounting groove A121, and the needle bodies A-132 pass through the slot holes A121 and extend to the interior of the shielding groove A125.

[0064] To solve the problem of installing the pin ledge 23 inside the seat base 22, as Fig. 9 , Fig.10 As shown, one end of the seat base 22 is provided with a mounting groove B221, and the other end is extended to form a plurality of partitions B222 that are distributed laterally. The number of partitions B222 is one less than the number of partitions A122. In this embodiment, the number of partitions A122 is set to four, and the ends of multiple partitions B222 are connected. Shielding grooves B225 are provided on both end faces of each partition B222. The number of shielding grooves B225 on each end face is consistent with the number of pin sill members 23, and is set to fifty. The side wall of the mounting groove B221 is provided with slot holes B223, which is consistent with the number of needle bodies B-232. When the pin sill member 23 is assembled to the interior of the seat base 22, the pin sill member 23 is located inside the mounting groove B221, and the needle body B-232 passes through the slot hole B223 and extends to the interior of the shielding groove B225.

[0065] In this embodiment, the needle body A-132 on the jack sill member 13 contacts the needle body B-232 on the pin sill member 23 to form a transmission channel. Transmission channels in different rows are separated by contacting partitions A122 and B222, and transmission channels in the same row are separated by slots A121 and shielding slots 125A. At the same time, the head base 12 shields the jack sill member 13, and the seat base 22 shields the pin sill member 23, so that the electromagnetic shielding effect between single transmission channels is good, thereby ensuring the high transmission rate of the connector.

[0066] To ensure the stability of the jack sill 13 installed inside the head base 12, Figure 3 , Figure 4 , Figure 5 , Figure 6 As shown, a plastic convex rib A135 is provided on the door member body A131, and the plastic convex rib A135 is arranged opposite to the needle body A132; a groove A171 for accommodating the plastic convex rib A135 is provided on the plug cover 17; a plastic convex rib A136 is provided on the door member body A131, and the plastic convex rib A136 is arranged opposite to the needle body A133; a limiting groove A124 for accommodating the plastic convex rib A136 is provided on the bottom wall of the mounting groove A121; a step groove A137 is provided on the door member body A131, and a step A172 matching the step groove A137 is provided on the plug cover 17.

[0067] After the plug connector 10 is assembled, the plastic rib A2136 is located inside the installation groove A121 to ensure the position of the jack ridge piece 13 in the length direction, the plastic rib A135 is located inside the groove A171, and the step A172 cooperates with the step groove A137 to ensure the position of the jack ridge piece 13 in the length direction and the plug-in direction, and to ensure the position stability of the jack ridge piece 13 inside the head base 12.

[0068] To ensure the stability of the pin ledge 23 when installed inside the base 22, Figure 8 , Fig. 9 , Fig.10 , Fig.11 As shown, a plastic convex rib B235 is provided on the door member body B231, and the plastic convex rib B235 is arranged opposite to the needle body B232, and a groove B241 for accommodating the plastic convex rib B235 is provided on the socket cover plate 24; a plastic convex rib B236 is provided on the door member body B231, and the plastic convex rib B236 is arranged opposite to the needle body B233, and a limiting groove B224 for accommodating the plastic convex rib B236 is provided on the bottom wall of the mounting groove B221; a step groove B237 is provided on the door member body B231, and a step B242 cooperating with the step groove B237 is provided on the socket cover plate 24.

[0074] The guide column 25 is rotatably matched with the socket housing 21, and a milled flat surface B251 is provided on the guide column 25. The socket housing 21 is threadedly matched with a screw B27, and the head of the screw B27 matches with the milled flat surface B251. After the guide column 25 is adjusted to a suitable key position, the screw B27 is threadedly matched with the socket housing 21, and the head of the screw B27 matches with the corresponding milled flat surface B251 to position the guide column 25 in the circumferential direction. The guide column 25 can be adjusted in four directions by the screw B27.

[0075] Since the key positions of the guide sleeve 15 on the plug connector 10 and the guide post 25 on the socket connector 20 can be adjusted, that is, in the present technical solution, sixteen key position modes can be provided.

[0076] The connector uses BGA welding to achieve connection with the PCB board. Specifically, in the plug connector 10, the tin block A134 is welded with the PCB board A, and the PCB board A is connected to the plug housing 11 through the printed circuit board locking screw A19;

[0077] In the socket connector 20, the tin block B234 is welded to the PCB board B, and the PCB board B is connected to the socket housing 21 through the locking printed circuit board screws B29.
