Detailed Implementation

[0052] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions of the present invention will be clearly and completely described below in conjunction with the embodiments. Example

[0053] like Figure 1 , Figure 2 , Figure 3 , Figure 6 , Figure 7 , Figure 8 , Figure 11 As shown, the high-speed connector with coplanar mounting includes a plug connector 10 and a socket connector 20 that can be plugged in and out. The plug connector 10 includes a plug housing 11, and a head base 12 is assembled in the middle cavity of the plug housing 11. The head base 12 is equipped with a plurality of socket retainers 13 arranged in parallel. In this embodiment, there are fifty socket retainers 13. A plug cover plate 17 is assembled at the tail end opening of the plug housing 11 by a locking cover plate screw A18. In this embodiment, the head end is the plug-in end of the connector, and the tail end is the mounting end that mates with the PCB board.

[0054] The socket retainer 13 includes a retainer body A131. One end of the retainer body A131 is provided with a plurality of pins A-132 and the other end is provided with a plurality of pins A-2133. In this embodiment, there are eight pins A-132 and eight pins A-2133. The extension lines of pins A-132 and pins A-2133 are perpendicularly intersecting each other. After the pins A-2133 penetrate the upper opening of the plug housing 11, they are fitted with a solder block A134.

[0055] The socket connector 20 includes a socket housing 21. A base 22 is assembled 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. A plurality of pin retainers 23 are assembled inside the base 22 and arranged in parallel. In this embodiment, there are fifty pin retainers 23. A socket cover 24 is assembled at the tail end opening of the socket housing 21 by means of a locking cover plate screw B28.

[0056] The pin retainer 23 includes a retainer body B231. One end of the retainer body B231 is provided with a plurality of pins B-232 and the other end is provided with a plurality of pins B-233. In this embodiment, there are eight pins B-232 and eight pins B-233. The extension lines of pins B-232 and pins B-233 intersect perpendicularly. After the pins B-233 penetrate the upper opening of the socket housing 21, they are fitted with a solder block B234.

[0057] The number of pins A-132 and pins 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 housing 11. Pins A-132 and pins B-232 contact to form a transmission channel. Solder blocks A134 and B234 are coplanar.

[0058] The high-speed connector with coplanar mounting in this technical solution consists of a plug connector 10 and a socket connector 20 that can be plugged in and out. The plug connector 10 includes a plug housing 11, a head base 12, and a socket retainer 13. The socket connector 20 includes a socket housing 21, a base 22, and a pin retainer 23. In the socket retainer 13, the extension lines of pin A-132 and pin A-2133 are perpendicularly intersecting. In the pin retainer 23, the extension lines of pin B-232 and pin B-233 are perpendicularly intersecting. This allows pin A-132 and pin B-232 to contact and form a transmission channel, while solder blocks A134 and B234 are coplanar, thus achieving coplanar mounting of the connector.

[0059] The connector in this technical solution achieves high transmission rate while meeting the requirement of coplanar mating, reducing signal interference loss. It features high arrangement density, high density, and high transmission rate, making it suitable for high-speed data transmission on coplanar boards within the limited space of miniaturized military equipment architecture systems.

[0060] like Figure 6 , Figure 11 As shown, the needle body A-132 is provided with arc-shaped part A-1321 and arc-shaped part A-1322, and the needle body B-232 is provided with arc-shaped part 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 of the insertion hole retainer 13 and the insertion pin retainer 23.

[0061] When the plug connector 10 and the socket connector 20 are inserted and mated, the pin body A-132 and the pin body B-232 deform. The outer arc surface of the arc part A-1322 and the outer arc surface of the arc part B-2321 fit together and make elastic contact, ensuring the convenience of insertion. At the same time, the elastic contact and multi-point contact between the pin body A-132 and the pin body B-232 ensure the reliability of signal contact.

[0062] To solve the problem of installing the socket retainer 13 inside the head base 12, such as Figure 4 , Figure 5As shown, one side of the head base 12 is provided with a mounting groove A121, and the other side extends to form a plurality of horizontally distributed partitions A122. In this embodiment, the number of partitions A122 is set to five. Each end face of the partitions A122 is provided with a shielding groove A125. The number of shielding grooves A125 on each end face is the same as the number of insertion hole retainers 13, which is set to fifty. The side wall of the mounting groove A121 is provided with a number of slots A123 that are the same as the number of needles A-132. When the insertion hole retainers 13 are assembled into the head base 12, the insertion hole retainers 13 are located inside the mounting groove A121, and the needles A-132 pass through the slots A123 and extend into the interior of the shielding grooves A125.

[0063] To solve the problem of installing the pin retainer 23 inside the base 22, such as Figure 9 , Figure 10 As shown, one end of the base 22 is provided with an installation groove B221, and the other end extends to form a plurality of horizontally distributed partitions B222. 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. The ends of the plurality of partitions B222 are connected. Each partition B222 has a shielding groove B225 on both end faces. The number of shielding grooves B225 on each end face is the same as the number of pin retainers 23, which is set to fifty. The side wall of the installation groove B221 has a number of slots B223 that are the same as the number of pins B-232. When the pin retainer 23 is assembled into the interior of the base 22, the pin retainer 23 is located inside the installation groove B221, and the pins B-232 pass through the slots B223 and extend into the interior of the shielding grooves B225.

[0064] In this embodiment, the pin A-132 on the socket retainer 13 and the pin B-232 on the pin retainer 23 contact to form a transmission channel. Transmission channels in different rows are separated by contacting partitions A122 and B222, while transmission channels in the same row are separated by slot A123 and shielding slot 125A. At the same time, the head base 12 shields the socket retainer 13, and the base base 22 shields the pin retainer 23, which makes the electromagnetic shielding effect between individual transmission channels good and ensures the high transmission rate of the connector.

[0065] To ensure the stability of the insertion socket retainer 13 installed inside the head base 12, such as Figure 3 , Figure 4 , Figure 5 , Figure 6As shown, the main body A131 of the retainer is provided with a plastic rib A-135, which is positioned opposite to the needle body A-132; the plug cover plate 17 is provided with a groove A171 for accommodating the plastic rib A-135; the main body A131 of the retainer is provided with a plastic rib A-2136, which is positioned opposite to the needle body A-2133; the bottom wall of the mounting groove A121 is provided with a limiting groove A124 for accommodating the plastic rib A-2136; the main body A131 of the retainer is provided with a stepped groove A137, and the plug cover plate 17 is provided with a step A172 that mates with the stepped groove A137.

[0066] After the plug connector 10 is assembled, the plastic protrusion A136 is located inside the mounting groove A121 to ensure the position of the socket retainer 13 in the length direction. The plastic protrusion A135 is located inside the groove A171. The step A172 and the step groove A137 cooperate to ensure the position of the socket retainer 13 in the length direction and the insertion direction, and to ensure the positional stability of the socket retainer 13 inside the head base 12.

[0067] To ensure the stability of the pin retainer 23 installed inside the base 22, such as Figure 8 , Figure 9 , Figure 10 , Figure 11 As shown, the main body B231 of the retainer is provided with a plastic rib B-235, which is positioned opposite to the needle body B-232. The socket cover plate 24 has a groove B241 for accommodating the plastic rib B-235. The main body B231 of the retainer is provided with a plastic rib B-236, which is positioned opposite to the needle body B-233. The bottom wall of the mounting groove B221 has a limiting groove B224 for accommodating the plastic rib B-236. The main body B231 of the retainer is provided with a stepped groove B237, and the socket cover plate 24 has a step B242 that mates with the stepped groove B237.

[0068] After the plug connector 10 is assembled, the plastic protrusion B236 is located inside the limiting groove B224 to ensure the position of the pin retainer 23 in the length direction. The plastic protrusion B1235 is located inside the groove B241. The step B242 and the step groove B237 cooperate to ensure the position of the pin retainer 23 in the length direction and the insertion direction, and to ensure the positional stability of the pin retainer 23 inside the base 22.

[0069] In this technical solution, by ensuring the positional stability of the socket retainer 13 inside the head base 12 and the positional stability of the pin retainer 23 inside the base 22, the stability of the contact between the pin retainer 23 and the socket retainer 13 is improved, thus ensuring the reliability of signal contact.

[0070] like Figure 2 , Figure 3 , Figure 7 , Figure 8 , Figure 10 As shown, key ribs 226 are provided at both ends of the base 22, and key grooves matching the key ribs 226 are provided on the inner wall of the socket housing 21 and the inner wall of the plug housing 11. While improving the stability of the base 22 installed inside the socket housing 21, the different number of key ribs 226 at both ends of the base 22 realizes the anti-misinsertion operation when the plug connector 10 and the socket connector 20 are mated.

[0071] like Figure 2 , Figure 3 , Figure 7 , Figure 8 As shown, the head end of the plug housing 11 is provided with a guide sleeve 15, and the head end of the socket housing 21 is provided with a guide post 25. When the plug connector 10 and the socket connector 20 are inserted and mated, the guide post 25 is inserted into the interior of the guide sleeve 15. The mating arrangement of the guide sleeve 15 and the guide post 25 has a guiding function when the connectors are inserted and mated.

[0072] The guide sleeve 15 is rotatably engaged with the plug housing 11. The guide sleeve 15 is provided with a milled flat surface A151. The plug housing 11 is threaded with a screw A16. The head of the screw A16 engages with the milled flat surface A151. After the guide sleeve 15 is adjusted to the appropriate key position, the screw A16 engages with the plug housing 11, and the head of the screw A16 engages with the corresponding milled flat surface A151 to position the guide sleeve 15 in the circumferential direction. The guide sleeve 15 can be adjusted in four directions by the screw A16.

[0073] The guide post 25 is rotatably engaged with the socket housing 21. The guide post 25 is provided with a milled flat surface B251. The socket housing 21 is threaded with a screw B27. The head of the screw B27 engages with the milled flat surface B251. After the guide post 25 is adjusted to the appropriate key position, the screw B27 engages with the socket housing 21, and the head of the screw B27 engages with the corresponding milled flat surface B251 to position the guide post 25 in the circumferential direction. The guide post 25 can be adjusted in four directions by the screw B27.

[0074] Since the guide sleeve 15 on the plug connector 10 and the guide post 25 on the socket connector 20 can both be adjusted, this technical solution can provide sixteen key positions.

[0075] The connector uses BGA soldering to connect with the PCB board. Specifically, in the plug connector 10, the solder block A134 is soldered to the PCB board A, and the PCB board A is connected to the plug shell 11 by the locking PCB screw A19.

[0076] In the socket connector 20, the solder block B234 is soldered to the PCB board B, and the PCB board B is connected to the socket housing 21 by the PCB screw B29.

[0077] To achieve precise positioning between the plug connector 10 and the PCB board A, such as Figure 2 , Figure 3 As shown, the end face of the plug housing 11 that mates with the PCB board A is fitted with a positioning pin 14.

[0078] To achieve precise positioning between the socket connector 20 and the PCB board B, such as Figure 7 , Figure 8 As shown, the socket housing 21 is fitted with a positioning pin 26 at the end face of the PCB board B with an interference fit.

[0079] The above embodiments are only used to illustrate the technical solutions of the present invention, and are not intended to limit it.
