Description

Technical Field

[0001] This invention relates to the field of connector technology, and more particularly to high-speed connectors. Background Technology

[0002] In fields such as high-capacity storage and high-speed communication, connectors and cable assemblies are used to connect different circuit boards within equipment and between circuit boards and chassis panels. With the rapid development of information technology and the continuous increase in data processing speed, equipment has increasingly higher requirements for signal transmission rates and the quality of high-speed transmission. At the same time, it requires connectors to be smaller and smaller, i.e., signal density to be larger and larger. Therefore, how to ensure signal impedance matching and reduce mutual interference between signals under small pitch conditions has become a challenge for improving connector speed.

[0003] In view of this, the inventors of this application have invented a high-speed connector with high transmission rate and full-link shielding. Summary of the Invention

[0004] This invention addresses the shortcomings of existing technologies by providing a high-speed connector.

[0005] The plug connector and socket connector involved in this invention, after mating, form multiple transmission paths that can be used to transmit high-speed differential signals. The multiple transmission paths are isolated from each other by a 360° shielding method of the metal shell. At the same time, the locking accessory completely locks them, which significantly improves the overall vibration and shock resistance of the connector. The reliable connection between the two enables the transfer of high-speed signals between the cable and the PCB board.

[0006] The present invention solves the above-mentioned technical problems through the following technical means: a high-speed connector, including a straight plug and a right-angle socket, wherein the straight plug is a movable end, the right-angle socket is electrically connected to the PCB board, and the straight plug and the right-angle socket are detachably fixed.

[0007] The straight plug includes a metal shell, several signal pin assemblies, and multiple bases. The bases are fixed inside the mating end of the metal shell of the plug, and the front end of the signal pin assembly is fixed inside the base hole.

[0008] The bent socket includes a metal housing, multiple bases, and several socket contacts. The bases are fixed inside the metal housing, and the socket contacts are fixedly inserted inside the bases, with the front ends of the socket contacts extending to the outside of the bases.

[0009] The rear end of the metal base housing has multiple cavities. The rear end of the socket contact extends through the cavity to the outside of the metal base housing. The part of the socket contact located outside the metal base housing is electrically connected to the PCB board. The cavities are separated by metal walls.

[0010] When a straight plug is plugged into a right-angle socket, the front end of the socket contact is inserted into the base hole, and the signal pin assembly is inserted into the socket contact. The signal pin assembly and the socket contact are electrically connected to form an independent link unit. The link unit is shielded 360 degrees by a metal shell, a base, a cavity, and a metal base shell.

[0011] Furthermore, the metal housing mating end protrudes from the metal housing, and the metal housing mating end is provided with multiple unit cavities. The base is fixed in the unit cavity, and the signal pin assembly tail end is fixed with an RF coaxial cable. The RF coaxial cable extends from the opposite side of the metal housing mating end, and the opposite end of the metal housing mating end is provided with a potting cavity.

[0012] Furthermore, the socket contact includes a long socket contact and a short socket contact, both of which are fixedly inserted into the base. The front ends of both the long and short socket contacts extend to the outside of the base. The long and short socket contacts are respectively fixed in corresponding base holes on the base. The socket contact located at the front end of the base hole is the mating end, and the socket contact located at the rear end of the base hole is the welding end. The welding end is fixed to the PCB board. A potting step is provided between the mating end and the welding end. The potting step is used for potting and fixing the base unit after it is assembled into the metal base shell. Limiting steps for axial positioning are fixed at the upper and lower ends of the base. Second air gaps for increasing characteristic impedance are opened on both sides of the base.

[0013] Furthermore, the signal needle assembly includes a nano-needle contact and a needle body. The tail end of the nano-needle contact is crimped to the needle body, and the front end of the nano-needle contact is a mating end. The tail end of the needle body is welded to the inner conductor of the coaxial cable. The connection between the two needle bodies and the two coaxial cables is fixed inside the positioning block. The outer conductor of the coaxial cable is welded to the welding area on the positioning block. The welding between the positioning block and the radio frequency coaxial cable achieves a 360-degree connection between the outer shell and the cable shielding layer. The front end of the positioning block extends forward on the upper and lower sides to form an extension arm.

[0014] Furthermore, a first air gap is provided on both sides of the base, the needle body is fixed in the first mounting hole, and the extension arm on the positioning block is close to the first positioning step on the plastic base.

[0015] Furthermore, two protruding ribs are fixed at the end of the unit cavity away from the metal shell of the plug, and a mating cavity is opened at the front end of the metal shell. The front end of the plug contact is located in the mating cavity, and its shape is an irregular rectangle. The mating cavity is adapted to the shape of the mating end of the metal shell.

[0016] Furthermore, a fixing plate is provided at the rear end of the metal base shell, and multiple plate grounding pins are fixed on the surface of the fixing plate; positioning holes are designed at the two side edges of the fixing plate, and the opening of the positioning hole is a beveled structure, and multiple shell grounding pins are fixed on the surface of the metal base shell.

[0017] Furthermore, the straight plug also includes a screw assembly. Grooves are provided on both sides of the mating end of the metal shell, and round holes are provided on both sides of the opposite end of the mating end of the metal shell. The round holes communicate with the grooves, and the screw assembly passes through the round holes and grooves in sequence. The screw assembly is fixed in the round holes.

[0018] The right-angle socket also includes locking nuts, two of which are fixed to both ends of the metal housing and used to lock and secure it with the screw assembly on the plug.

[0019] Furthermore, a square step is fixed to the front end of the locking nut, and the inside of the locking nut has an internal thread that locks with the locking thread. The tail of the locking nut is a round step, which is used to rivet with the positioning hole on the fixing plate. Locking holes are opened on both sides of the metal base shell for assembling the locking nut. The locking nut passes through the locking hole. A second positioning step is opened at the front end of the locking hole, and the square step is located in the second positioning step. A through second mounting hole is opened from the top to the bottom of the metal base shell. A positioning recess is provided in the middle of the locking nut, and the mounting screw passes smoothly through the locking nut.

[0020] The beneficial effects of this invention are:

[0021] (1) In the high-speed connector of the present invention, the front end of the signal pin assembly is fixed in the base hole, and multiple signal pin assemblies are shielded from each other by the base, thereby achieving mutual shielding of multiple signal pin assemblies located in the straight plug; the long socket contact and the short socket contact are respectively fixed in the corresponding base holes on the base, forming a small base unit, which is shielded from each other by the base, thereby shielding the multiple socket contacts located in the bent socket. When the straight plug is connected to the bent socket, the signal pin assembly and the socket contact are electrically connected to form an independent link unit. The metal shell, base, base, cavity, and metal shell shield the individual link unit, resulting in extremely low crosstalk.

[0022] (2) In the high-speed connector of the present invention, the outer conductor of the coaxial cable is welded to the welding area on the positioning block to fix them together, and at the same time, the connection between the pin body and the coaxial cable is metal shielded, that is, the tail end of the signal pin assembly is also metal shielded, thus realizing full-link isolation of the link unit.

[0023] (3) When the high-speed connector of the present invention is connected to the straight plug and the bent socket, the front end of the locking screw assembly is screwed into the locking nut to realize the locking function with the bent socket, effectively improving the connector's performance against strong vibration, impact and other harsh mechanical environments.

[0045] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0046] It should be noted that when a component is said to be "fixed to" another component, it can be directly attached to the other component or there may be an intervening component. When a component is said to be "connected to" another component, it can be directly connected to the other component or there may be an intervening component. Example

[0047] See Figure 1 , 2 An embodiment of the present invention illustrates a high-speed connector, a straight plug 1 and a right-angle socket 2. The straight plug 1 connector serves as the movable end and is connected to the coaxial cable by welding a cable. The right-angle socket 2 connector is connected to the PCB board by through-hole welding. The straight plug 1 and the right-angle socket 2 are completely locked together by a locking accessory, which has the characteristics of reliability and environmental resistance.

[0048] In a preferred embodiment of the present invention, a connector with three units is shown. The high-speed connectors of different specifications differ only in the number of cores and size, and are completely identical in terms of structure and high-speed transmission performance.

[0049] The connector of this invention has a virtual modular structure. The contacts are made of micro-pins, which are superior to those made of stamped spring sheet structure. Two contacts are combined to form a differential pair for signal transmission. Each differential is fixed at the corresponding position on the shell to form an independent unit. The independent units are shielded from each other by a metal shielding layer, realizing full-link isolation between them. It has the characteristics of good shielding effect, small size and high transmission performance.

[0050] See Figure 3 The present invention illustrates an overall structural diagram of a straight plug 1 in a high-speed connector according to an embodiment of the present invention. It includes a metal housing 10, two screw assemblies 14, multiple bases 11, multiple signal pin assemblies 12, and multiple radio frequency coaxial cables 13.

[0051] See Figure 4 , Figure 5 This is a schematic diagram of the metal housing 10 in a high-speed connector straight plug 1 according to an embodiment of the present invention. A base 11 is fixed inside the mating end of the metal housing 10. Specifically, the mating end of the metal housing 10 protrudes from the metal housing 10, and the mating end of the metal housing 10 is provided with multiple unit cavity 102 structures. The base 11 is fixed inside the unit cavity 102 structures. The front end of the signal pin assembly 12 is fixed inside the hole of the base 11. Multiple signal pin assemblies 12 are shielded from each other by the base 11. The base 11 is a modular plastic base, and the signal pin assembly 12 is a nano-needle contact. The tail end of the signal pin assembly 12 is fixed to the RF coaxial cable 13. The RF coaxial cable 13 extends from the opposite side of the mating end of the metal housing 10, as shown below. Figure 3 As shown; grooves 103 are provided on both sides of the mating end of the metal shell 10, and round holes 104 are provided on both sides of the opposite end of the mating end of the metal shell 10. The round holes 104 are connected to the grooves 103. The screw assembly 14 passes through the round holes 104 and the grooves 103 in sequence, and the screw assembly 14 is fixed in the round holes 104.

[0052] See Figure 4 , Figure 5Two protruding ribs 101 are fixed at the end of the unit cavity 102 away from the metal shell 10 of the plug, which can ensure the anti-skewing and anti-reverse installation function when the straight plug 1 and the bent socket 2 are connected; the metal shell 10 has a potting cavity 106 at the opposite end of the connecting end for fixing the radio frequency coaxial cable 13; the upper and lower side walls of the metal shell 10 are designed with multiple anti-slip grooves 105 and two mounting holes 107.

[0053] See Figure 6 The signal needle assembly 12 includes a nanoneedle contact 120 and a needle body 121. The tail end of the nanoneedle contact 120 is connected to the needle body 121 by crimping. The front end of the nanoneedle contact 120 is a butt joint. The tail end of the needle body 121 is welded to the inner conductor of the coaxial cable 13. A gasket 17 is fitted on the surface of the needle body 121, and the gasket 17 located between the needle body 121 and the coaxial cable 13 serves a supporting function. The connection between the two needle bodies 121 and the two coaxial cables 13 is fixed in the positioning block 16. The outer conductor of the coaxial cable 13 is welded to the welding area 161 on the positioning block 16 to fix them together and to provide metal shielding for the connection between the needle bodies 121 and the coaxial cables 13. The front end of the positioning block 16 extends forward on the upper and lower sides to form an extension arm 160, which serves to support the plastic base 11. Figure 7 As shown.

[0054] See Figure 7 The diagram shows the assembly structure of the signal pin assembly 12 and the plastic base 11. The base 11 has first air gaps 112 on both sides to reduce the dielectric constant, thus ensuring the impedance matching performance of the signal pin assembly 12. The pin body 121 is fixed inside the first mounting hole 110. The two extension arms 160 on the positioning block 16 are pressed against the first positioning step 111 on the plastic base 11 to provide support and form a base assembly. Multiple base assemblies are arranged in parallel and then installed one by one into the metal casing 10.

[0055] See Figure 8 The diagram shows the internal structure of the base assembly assembled into the metal housing 10. During assembly, the positioning block 16 supports the base 11 to move forward, and the metal housing 10 and the positioning block 16 are connected by interference fit. After being pressed into place, the RF coaxial cable 13 is fixed inside the metal housing 10 by filling the potting cavity 106 with glue. The base 11 is located in the unit cavity 102 inside the metal housing 10, and the base 11 is isolated from each other by the metal housing 10.

[0056] See Figure 7The diagram shows the assembly of the screw assembly 14 and the metal housing 10. The screw assembly 14 comprises three parts: a front sleeve 140, a rear sleeve 141, and a fixing post 142. The fixing post 142 passes through the mounting hole 107 on the metal housing 10 and is fixed in the front sleeve hole 1400 on the front sleeve 140 and the rear sleeve hole 1410 on the rear sleeve 141. The fixing post 142 has small holes 1420 at both ends. The connection between the front sleeve 140 and the rear sleeve 141 is achieved by riveting the small holes 1420. The diameter of the rear sleeve 141 is larger than the boss 108 on the metal housing 10, thus restricting the screw assembly 14 from moving forward. At the same time, the step 1401 on the front sleeve 140 is also larger than the boss 108, restricting the screw assembly 14 from moving backward. Therefore, the screw assembly 14 can only move back and forth a certain distance within the round hole 104 on the metal housing 10, thus achieving the function of locking the screw assembly 14 to prevent it from falling off. In addition, the front end of the front sleeve 140 is designed with a locking thread 1402, which can achieve the locking function with the bent socket 2.

[0057] See Figure 11 The diagram shows the structure of the bent socket 2. The bent socket 2 includes a metal housing 20, two locking nuts 25, multiple modular base 24, multiple socket contacts, multiple housing grounding pins 201 and plate grounding pins 231, and a fixing plate 23. The socket contacts include long socket contacts 21 and short socket contacts 22.

[0058] Combination Figure 11 and Figure 18 As shown, the base 24 is fixed inside the metal housing 20, and the socket contact is fixedly installed inside the base 24. The front end of the socket contact extends to the outside of the base 24. That is, both the long socket contact 21 and the short socket contact 22 are fixedly installed inside the base 24, and the front ends of both the long socket contact 21 and the short socket contact 22 extend to the outside of the base 24.

[0059] Specifically, see Figure 12 , Figure 13 The metal housing 20 is a rectangular structure with a mating cavity 200 at its front end for mating. The cavity 200 is irregularly rectangular and its shape matches the mating end of the metal housing 10. The mating end of the metal housing 10 is inserted into the cavity 200, ensuring that the straight plug 1 and the right-angle socket 2 are not plugged in backwards or at an angle. The front end of the socket contact is located within the cavity 200. The rear end of the metal housing 20 has multiple cavities 206 for assembling internal components. The rear end of the socket contact extends through the cavities 206 to the outside of the metal housing 20. The portion of the socket contact located at the rear end of the metal housing 20 is electrically connected to the PCB board. Figure 20 As shown. Cavities 206 are separated from each other by metal walls, forming independent units with metal shielding at the rear end of the socket.

[0060] When the straight plug 1 is plugged into the right-angle socket 2, the front end of the socket contact is inserted into the hole of the base 11, and the signal pin assembly 12 is inserted into the socket contact. The signal pin assembly 12 and the socket contact are electrically connected to form an independent link unit. The link unit is shielded 360 degrees by the metal shell 10, the base 24, the base 11, the cavity 206, and the metal base shell 20, resulting in extremely low crosstalk.

[0061] See Figure 11 As shown, a fixing plate 23 is provided at the rear end of the metal base shell 20, which fixes multiple modular base bases 24, multiple long socket contact pieces 21 and short socket contact pieces 22. The fixing plate 23 is made of metal, and multiple plate grounding pins 231 are fixed on the surface of the fixing plate 23. The multiple plate grounding pins 231 are fixed on the fixing plate 23 by press fitting. Positioning holes 232 are designed on both sides of the fixing plate 23. The opening of the positioning hole 232 is a beveled structure 2321, which is used for riveting fixation after the locking nut 25 is assembled.

[0062] See Figure 11 As shown, multiple shell grounding pins 201 are fixed on the surface of the metal base housing 20. The shell grounding pins 201 are fixed to the metal base housing 20 by press fitting. Two locking nuts 25 are fixed at both ends of the metal base housing 20 for locking and fixing with the screw assembly 14 on the plug 1.

[0063] Please see Figure 15 , Figure 16 As shown, the front end of the locking nut 25 is fixed with a square step 251, the inside of the locking nut 25 has an internal thread 252 that locks with the locking thread 1402, and the tail end of the locking nut 25 is a round step 253, which is used to rivet with the positioning hole 232 on the fixing plate 23 to achieve tight fixation between the metal base shell 20 and the fixing plate 23.

[0064] See Figure 12 As shown, the metal housing 20 has locking holes 203 on both sides for assembling locking nuts 25. The locking nuts 25 pass through the locking holes 203. A second positioning step 204 is provided at the front end of the locking holes 203, and a square step 251 is located within the second positioning step 204. Figure 11 As shown, this ensures that the locking nut 25 will not rotate; the metal housing 20 has a through second mounting hole 205 from top to bottom, as shown. Figure 13 As shown.

[0065] A positioning recess 254 is designed in the middle of the locking nut 25. Its function is to prevent the mounting screw 31 from passing through after the PCB board is installed in the bent socket 2, so that the mounting screw 31 can pass smoothly through the locking nut 25. Figure 20As shown, the mounting screw 31 passes through the second mounting hole 205 and the positioning recess 254 in sequence, and is then fixed to the PCB board.

[0066] See figure Figure 17 , Figure 18 The diagram shows the assembly structure of the long socket contact 21, the short socket contact 22, and the base 24 in the bent socket 2. The long socket contact 21 and the short socket contact 22 are respectively fixed in the corresponding base holes 240 on the base 24, forming a small base unit. They are shielded from each other by the base 24, forming a 360-degree full shield with extremely low crosstalk. The socket contact at the front end of the base hole 240 is the mating end 210 (i.e., the front end of the socket contact), and the socket contact at the rear end of the base hole 240 is the welding end 212 (i.e., the tail end of the socket contact). The welding end 212 is fixed to the PCB board. A potting step 211 is provided between the welding ends 212. The potting step 211 is used for potting and fixing after the base unit is assembled to the metal base shell 20. The upper and lower ends of the base 24 are fixed with limiting steps 241 for axial positioning. The two sides of the base 24 are provided with a second air gap 242 to improve the characteristic impedance, thereby ensuring the impedance matching performance of the contacts.

[0067] See Figure 19 The diagram shows the internal structure of the base assembly assembled into the metal housing 20. During assembly, each small base unit is inserted into the cavity 206 on the metal housing 20. After being inserted into place, the limiting step 241 on the base 24 fits tightly with the step on the metal housing 20. Then, the potting step 211 is potted and dried to achieve overall fixation between the base unit and the metal housing 20.

[0068] See Figure 20 The diagram shown is a schematic representation of the high-speed connector bend socket 2 assembled onto a PCB board according to a preferred embodiment of the present invention. The metal housing 20 and the fixing plate 23 are fixed together by riveting the circular steps 253 on two locking nuts 25. Simultaneously, the positioning recesses 254 on the locking nuts 25 are coaxial with the mounting holes 107 on the metal housing 20, allowing the screws 31 to pass through, thus achieving a locking and fixing effect between the connector socket 2 and the PCB board 30.

[0069] See Figure 21 The diagram shown is a schematic representation of the differential pair distribution of a high-speed connector according to a preferred embodiment of the present invention. Inside the connector, each differential pair is arranged regularly and completely separated from each other by a metal shell, forming a 360° shield. In addition, the connector's signal ground is connected to the shell and distributed around the differential pairs, forming a good shielding effect.
