Detailed Implementation

[0042] 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.

[0043] Example 1

[0044] like Figure 1 , Figure 2 , Figure 3 , Figure 6 , Figure 7 , Figure 8 , Figure 10 , Figure 11 , Figure 12As shown, a double-bend parallel board high-speed connector includes a pluggable bend plug 1 and a bend socket 2. Both the bend plug 1 and the bend socket 2 are connected to the printed circuit board using a reflow soldering process. The bend plug 1 includes a plug housing 11. A head base 12 is assembled in a cavity A113 within the plug housing 11. Multiple socket contact assemblies 13 arranged in parallel are assembled in the head base 12. In this embodiment, forty socket contact assemblies 13 are provided. Each socket contact assembly 13 includes multiple components arranged in a series... The needles A134 are arranged sequentially from the outside. In this embodiment, there are eight needles A134. The middle of the multiple needles A134 is fitted with the same plastic A136. More specifically, the multiple needles A134 and the plastic A136 are fixed together by injection molding to ensure the stability of the relative position between the needles A134 and the plastic A136. The needle A134 has a plug end A and a mounting end A. The included angle between the plug end A and the mounting end A is 90 degrees. The mounting end A is equipped with a solder block A135. In this embodiment, the solder block A is square.

[0045] The bent socket 2 includes a socket housing 21. A base 22 is assembled in the cavity B211 of the socket housing 21. A plurality of pin contact components 23 are assembled in the base 22 and arranged in parallel. In this embodiment, there are forty pin contact components 23. Each pin contact component 23 includes a plurality of pins B234 arranged from the inside to the outside. In this embodiment, there are eight pins B234. The middle of the plurality of pins B234 is fitted with the same plastic B235. More specifically, the plurality of pins B234 and plastic B235 are fixed together by injection molding to ensure the stability of the relative position between the pins B234 and plastic B235. Each pin B234 has a plug-in end B and a mounting end B. The angle between the plug-in end B and the mounting end B is 90 degrees. The mounting end B is equipped with a solder block B236. In this embodiment, the solder block B236 is square.

[0046] Among them, the right-angle plug 1 is soldered to the printed circuit board A through solder block A135, and the right-angle socket 2 is soldered to the printed circuit board B through solder block B236. When the right-angle plug 1 and the right-angle socket 2 are plugged in, the plug end A and plug end B are distributed in parallel with the printed circuit board A and the printed circuit board B, and the solder block A135 and the solder block B236 are kept on the same horizontal plane to form a BGA array arrangement.

[0047] This technical solution discloses a double-bend parallel board high-speed connector used for high-speed data transmission between parallel printed circuit boards inside a chassis. In the bend plug 1, the angle between the insertion end A and the mounting end A of the pin body A134 is 90 degrees. It is soldered to the printed circuit board A by a solder block A135. The bend plug 1 and the printed circuit board A are installed at a right angle. In the bend socket 2, the angle between the insertion end B and the mounting end B of the pin body B234 is 90 degrees. It is soldered to the printed circuit board B by a solder block B236. The bend socket 2 and the printed circuit board B are installed at a right angle. After the bend plug 1 and the bend socket 2 are plugged in, the insertion end of the connector and the printed circuit board are parallel, realizing high-speed signal transmission between parallel boards.

[0048] To further enhance the positional stability between the needle body B234 and the plastic B235, such as Figure 12 As shown, the needle body B234 is provided with an elliptical opening 2342, and the plastic extends into the interior of the elliptical opening 2342, which can enhance the bonding and fixation of the plastic B235 of the needle body B234. The needle body B234 has a first folding section 2343 and a second folding section 2344. The first folding section 2343 is distributed on the seven outer needle bodies B234, and the second folding section 2344 is distributed on all needle bodies B234. The arrangement of the first folding section 2343 and the second folding section 2344 increases the needle body spacing between differential pairs, provides physical isolation, reduces the coupling of capacitance and inductance, and at the same time ensures impedance continuity, reduces reflection, and reduces crosstalk between adjacent differential pairs.

[0049] like Figure 6 , Figure 10 As shown, plastic A136 has a plastic hole A1361, which can ensure the impedance consistency of the socket contact 13 during signal transmission and ensure the crosstalk performance of the product. Plastic B235 has plastic holes B-2351 and B-2352, which can ensure the impedance consistency of the pin contact assembly 23 during signal transmission and ensure the crosstalk performance of the product.

[0050] like Figure 5 , Figure 6 , Figure 10 , Figure 11 As shown, needle body A134 and needle body B234 are formed by stamping, flipping and other processes. The plug end of needle body A134 and the plug end of needle body B234 both adopt a spring-type structure for docking with the docking end spring to achieve multi-contact contact, meet the requirements of vibration, impact and mechanical life, and also meet the high-speed transmission performance.

[0051] like Figure 5 , Figure 6 , Figure 10 , Figure 11As shown, the mounting end of the pin body A134 is provided with a pin body U-shaped groove A1341, and the solder block A135 is provided with an H-shaped structure A1351. The pin body U-shaped groove A1341 is assembled with the solder block A135 through the H-shaped structure A1351 to realize the soldering between the bent plug 1 and the printed circuit board A. When assembling the pin body A134 and the solder block A135, the mounting end of the pin body A134 is first riveted to the solder block A135, and then the solder block A135 and the mounting end of the pin body A134 are fixed by mechanical pressing.

[0052] like Figure 5 , Figure 6 , Figure 10 , Figure 11 As shown, the mounting end of the pin body B234 is provided with a pin body U-shaped groove B2341, and the solder block B236 is provided with an H-shaped structure B2361. The pin body U-shaped groove B2341 is assembled with the solder block B236 through the H-shaped structure B2361 to realize the soldering between the bent socket 2 and the printed circuit board B. When assembling the pin body B234 and the solder block B236, the mounting end of the pin body B234 is first riveted to the solder block B236, and then the solder block B236 and the mounting end of the pin body B234 are fixed by mechanical pressing. After the socket contact assembly 13 is assembled to the head base 12 and the pin contact assembly 23 is assembled to the base base 22, the solder blocks A135 and B236 are kept on the same horizontal plane to form a BGA array arrangement.

[0053] like Figure 1 , Figure 2 As shown, the plug housing 11 has an opening at its tail end. The right-angle plug 1 also includes a plug cover plate 15 that covers the opening at the tail end of the plug housing 11. The plug cover plate 15 and the plug housing 11 are threaded together by a locking screw A16. More specifically, the plug housing 11 has a threaded hole A112, and the locking screw A16 passes through the plug housing 11 and is threaded into the threaded hole A112. Figure 7 , Figure 8 As shown, the socket housing 21 has an opening at the tail end. The bent socket 2 also includes a socket cover 24 that covers the opening at the tail end of the socket housing 21. The socket cover 24 and the plug cover 15 are threaded together by a locking cover screw B27. More specifically, the socket housing 21 has a threaded hole B213. The locking cover screw B27 passes through the socket housing 21 and is threaded into the threaded hole B213. In this embodiment, there are four combinations of locking cover screw A16 and threaded hole A112, and four combinations of locking cover screw B27 and threaded hole B213, which are distributed in a matrix.

[0054] like Figure 1 , Figure 2As shown, the plug housing 11 is fitted with a positioning post A14 corresponding to the end face of the printed circuit board A via interference fit. The positioning post A14 facilitates precise positioning between the bent plug 1 and the printed circuit board A. The plug housing 11 and the printed circuit board A are connected by a locking screw A17, achieving a locking mechanism between the bent plug 1 and the printed circuit board A. Figure 7 , Figure 8 As shown, the socket housing 21 is fitted with a positioning post B26 on the end face of the printed circuit board B with an interference fit, which facilitates the precise positioning between the bent socket 2 and the printed circuit board B. The socket housing 21 and the printed circuit board B are connected by a locking screw B28, which realizes the locking setting between the bent socket 2 and the printed circuit board B, ensuring the stability of the connector in this technical solution during use.

[0055] like Figure 2 , Figure 8 As shown, the plug housing 11 is provided with a guide hole 111, and the socket housing 21 is provided with a guide post 25. When the right-angle plug 1 and the right-angle socket 2 are plugged in, the guide post 25 matches the guide hole 111, forming a primary guide for the right-angle plug 1 and the right-angle socket 2, which plays a guiding role during the plugging process.

[0056] like Figure 8 As shown, the socket housing 21 is provided with an internal thread 217, and the guide post 25 is provided with an external thread 253 that matches the internal thread 217. The internal thread 217 is provided with a step 214, and the guide post 25 is provided with a step 252 that corresponds to the step 214. The external thread 253 of the guide post 25 is threadedly connected to the internal thread 217 on the socket housing 21. At this time, the step 214 and the step 252 abut against each other, thereby fixing the socket housing 21 and the guide post 25 together. The guide post 25 is provided with a milled flat position 251. The milled flat position 251 facilitates the application of force by tools when installing and disassembling the guide post 25, increasing the ease of operation.

[0057] like Figure 2 As shown, the plug housing 11 is provided with a through hole A114 that communicates with the cavity A113; as Figure 8 As shown, the socket housing 21 is provided with through holes B-212 and B216 that are through the cavity B211. The through holes A114, B-212 and B216 are provided to dissipate heat from the connector during BGA soldering.

[0058] like Figure 2 , Figure 8 As shown, a key 215 is provided on the socket housing 21, and a key groove is provided on the side wall of the cavity A113 of the plug housing 11. When the right-angle plug 1 and the right-angle socket 2 are plugged in, the key 215 is located in the key groove. The matching arrangement of the key 215 and the key groove plays a role in preventing reverse insertion when the right-angle plug 1 and the right-angle socket 2 are plugged in.

[0059] To ensure the stability of the connector's internal structure, this technical solution has been further optimized, specifically as follows: The connection between the socket contact assembly 13 and the plug cover 15 is as follows... Figure 2 , Figure 5 As shown, the socket contact assembly 13 is provided with a raised rib A-131, and the plug cover plate 15 is provided with a groove A151 to accommodate the raised rib A-131. The raised rib A-131 and the groove A151 cooperate to ensure the positional accuracy of the socket contact assembly 13 in the length direction. The socket contact assembly 13 is provided with a positioning groove A138, and the plug cover plate 15 is provided with a boss A152 that matches the positioning groove A138. The positioning groove A138 and the boss A152 abut against each other to ensure that the socket contact assembly 13 will not move backward along the mating end direction, that is, it will not move backward in the connector width direction, thus ensuring the fixation of the position of the socket contact assembly 13.

[0060] Between the pin contact assembly 23 and the socket cover 24, such as Figure 8 , Figure 10 As shown, the pin contact assembly 23 is provided with a raised rib B-231, and the socket cover 24 is provided with a groove B241 to accommodate the raised rib B-231. The raised rib B-231 and the groove B241 cooperate to ensure the positional accuracy of the pin contact assembly 23 in the length direction. The pin contact assembly 23 is provided with a positioning groove B 237, and the socket cover 24 is provided with a boss B242 that matches the positioning groove B 237. The positioning groove B 237 abuts against the boss B242 to ensure that the pin contact assembly 23 will not move backward along the mating end direction, that is, it will not move backward in the connector width direction, thus ensuring the fixation of the position of the pin contact assembly 23.

[0061] Between the socket contact assembly 13 and the head base 12, such as Figure 4 , Figure 5 As shown, the socket contact assembly 13 is provided with a raised rib A132, a raised rib A33, and a barb A137. The head base 12 is provided with a recessed hole A121, a recessed hole A222, a rectangular hole A123, and a base hole A124. When the socket contact assembly 13 is assembled with the head base 12, the recessed hole A121 and the raised rib A333 cooperate to ensure the fixation of the socket contact assembly 13 in the head base 12. The recessed hole A222 and the raised rib A2132 cooperate to ensure the position of the socket contact assembly 13 in the length direction of the connector. The insertion end of the pin A134 passes through the rectangular hole A123 and cooperates with the base hole A124. The barb A137 of the pin is interference-fitted with the rectangular hole A123 to ensure the fixation of the position of the socket contact assembly 13 in the head base 12.

[0062] Between the pin contact assembly 23 and the base 22, such as Figure 9, Figure 10 As shown, the pin contact assembly 23 is provided with ribs B2232, B3233 and barbs B238. The base 22 is provided with recessed holes B1222, B223, base hole B224 and rectangular hole B225. When the pin contact assembly 23 is assembled with the base 22, the recessed hole B1222 mates with the rib B3233, the recessed hole B223 mates with the rib B222, the insertion end of the needle B234 passes through the rectangular hole B225 and mates with the base hole B224, and the barbs B238 are interference-fitted with the rectangular hole B225 to ensure the fixation of the pin contact assembly 23 in the base 22.

[0063] In this technical solution, a double-bend parallel plate high-speed connector includes a bend plug 1 with limiting structures added between the socket contact assembly 13 and the plug cover 15, and between the socket contact assembly 13 and the head base 12, to ensure the stability of the positions of the plug housing 11, head base 12, socket contact assembly 13, and plug cover 15. Similarly, in the bend socket 2, limiting structures are added between the pin contact assembly 23 and the socket cover 24, and between the pin contact assembly 23 and the base 22, to ensure the stability of the positions of the socket housing 21, base 22, pin contact assembly 23, and socket cover 24.

[0064] This ensures the stability of the connector and guarantees stable transmission.
