Description

Technical Field

[0001] This invention relates to connectors, and more particularly to a high-speed connector. Background Technology

[0002] With the continuous development of communication technology, the performance requirements for high-speed connectors are also increasing, especially at higher speeds, where the acceptability of crosstalk performance becomes increasingly stringent. Traditional high-speed connectors are susceptible to electromagnetic interference during high-frequency signal transmission, leading to signal distortion and increased errors. Although existing technologies construct shielding structures by incorporating contactable shielding elements within the plug and socket structures to address electromagnetic crosstalk, this method is no longer effective in solving the problem as transmission rates continue to rise, resulting in low electromagnetic wave shielding efficiency.

[0003] Currently, high-speed differential connectors typically use shielding plates on the differential modules to reduce interference between differential pairs from different modules during signal transmission. However, this shielding method has the following drawbacks: 1. At higher speeds, the crosstalk performance of existing high-speed connectors is unacceptable and cannot meet the requirements of high-frequency signal transmission. 2. Existing shielding structures cannot effectively solve the electromagnetic crosstalk problem as transmission rates continue to increase, resulting in low shielding efficiency for electromagnetic waves. 3. Current high-speed differential connectors often only shield the root of the contact insertion section, which cannot effectively shield the insertion part of the differential pair. This results in significant electromagnetic interference between the differential pairs, affecting the signal integrity of the entire transmission line. 4. Existing high-speed connectors have shortcomings in the structural design of plugs and sockets, making it difficult to achieve compactness, reliability, and ease of assembly, which affects the overall performance of the connector and the integrity of the transmitted signal.

[0023] like Figure 1 and Figure 2As shown, a high-speed connector includes a plug 2 and a socket 1. The plug 2 and socket 1 are inserted and locked by an interlocking mechanism 34. In this embodiment, as... Figure 9 and Figure 10 As shown, plug 2 includes a head base 31, as... Figure 15 As shown, the head base 31 has a mounting window, which is rectangular. A partition 35 is installed within the mounting window, dividing it into an upper mounting window 37 and a lower mounting window 36. A head terminal module is installed within the mounting window. Figure 11 As shown, the head terminal module includes a head molding body 20144 and a head signal transmission module 32. The head molding body 20144 includes a molding tail plate 46. Molding support plates 45 are installed vertically and vertically on the front end face of the molding tail plate 46. The head signal transmission module 32 is installed on the molding support plate 45, and the rear end of the signal transmission module is installed inside the molding tail plate 46. The upper and lower sets of head signal transmission modules 32 are arranged opposite to each other, and the cavity between the front ends of the upper and lower sets of head signal transmission modules 32 forms an insertion cavity. In this embodiment, as shown... Figure 12 As shown, the head signal transmission module 32 includes a head molding package, on which several head signal differential pairs 204 and head grounding springs 203 are molded. A set of head signal differential pairs 204 is located between every two head grounding springs 203. A head shielding assembly is also installed on the head molding package, such as... Figure 13 As shown, the head shielding assembly includes a long head shield 202 and a short head shield 205. The long head shield 202 includes a long head shielding plate 212, with two spaced-apart head shielding springs 211 at its front end. The long head shielding plate 212 has a first contact portion 218, a first bent connecting section 215, and a second contact portion 219. The first contact portion 218 and the second contact portion 219 are connected by the first bent connecting section 215. In this embodiment, the bending angle of the first bent connecting section 215 is 90 degrees. The short head shield 205 has a third contact portion 221, a second bent connecting section 225, and a fourth contact portion 228. The third contact portion 221 and the fourth contact portion 228 are connected by the second bent connecting section 225. In this embodiment, the bending angle of the second bent connecting section 225 is 90 degrees. The first contact portion 218 and the third contact portion 221 are connected by the head grounding spring 203, and the first contact portion 218 and the third contact portion 221 form a front shielding cavity. The second contact portion 219 and the fourth contact portion 228 contact and form a rear shielding cavity. The front end of the head signal differential pair 204 passes through the front shielding cavity, and the rear end of the head signal differential pair 204 is located in the rear shielding cavity. Several core wires 33 are also installed in the plastic-encapsulated tail plate 46. The several core wires 33 are connected to the rear end of the corresponding head signal differential pair 204. Therefore, the differential signal pair is completely wrapped by the head short shield 205 and the head long shield 202, thereby improving the shielding performance and enhancing the anti-interference ability of the head signal differential pair 204.

[0024] In this embodiment, as Figure 13 As shown, the first contact portion 218 has a third bending portion 214 on both sides, which bends towards the grounding spring. The end of the third bending portion 214 has a third flange 213, which contacts the lower surface of the corresponding head grounding spring 203. Therefore, the first contact portion 218 has an Ω-shaped structure. The third contact portion 221 has a fourth bending portion 216 on both sides, which bends towards the grounding spring. The end of the fourth bending portion 216 has a fourth flange 217, which contacts the upper surface of the corresponding head grounding spring 203. Therefore, the third contact portion 221 has an Ω-shaped structure. Thus, when the first contact portion 218 and the third contact portion 221 contact the grounding spring respectively, the two Ω-shaped structures completely enclose and shield the head signal differential pair 204, effectively solving the problem of unacceptable crosstalk at higher speeds, significantly reducing signal crosstalk, and improving signal transmission quality. Similarly, the second contact portion 219 is provided with a fifth bend 222, and the end of the fifth bend 222 is provided with a fifth flange 223. The fifth flange 223 contacts the bend section at the rear end of the corresponding head contact spring. The fourth contact portion 228 is provided with a sixth bend 226, and the end of the sixth bend 226 is provided with a sixth flange 227. The sixth flange 227 contacts the bend section at the rear end of the corresponding head contact spring. The second contact portion 219 and the fourth contact portion 228 also form an Ω-shaped structure, thereby making the rear end of the head signal differential pair 204... The part is also fully shielded. In this embodiment, the head signal differential pair 204 is soldered to the core wire 33, and the soldering position is located between the second contact part 219 and the fourth contact part 228, thereby reducing signal crosstalk and improving signal transmission quality. In this embodiment, since the rear end of the grounding spring is also bent, in order to ensure the grounding performance of the second contact part 219 and the fourth contact part 228, the sixth flange 227 on the fourth contact part 228 near the sixth bend 226 is in contact with the rear end of the grounding spring.

[0025] In this embodiment, as Figure 13As shown, the upper and lower surfaces of the head molding component are also provided with second positioning bosses 206, and third positioning notches 224 are opened on the fourth flange 217 and the third flange 213. The second positioning bosses 206 are engaged in the corresponding third positioning notches 224. Furthermore, the second positioning bosses 206 are cylindrical, and the third positioning notches 224 are semi-circular notches. The semi-circular notches on two adjacent fourth flanges 217 form a circular hole that matches the second positioning bosses 206. The second positioning bosses 206 are fitted into the corresponding circular holes. The semi-circular notch on edge 213 forms a circular hole that matches the second positioning boss 206. The second positioning boss 206 is installed in the corresponding circular hole. Therefore, the head long shield 202 and the head short shield 205 are positioned with the molding compound by the second positioning boss 206. In this embodiment, the molding compound has eight sets of head signal differential pairs 204. After the eight sets of head signal differential pairs 204 and the molding compound form a whole, they are connected to the core wire 33 of the cable, and then the head shield assembly is positioned and installed by the second positioning boss 206.

[0026] In this embodiment, as Figure 14 As shown, the encapsulated support plate 45 has a head receiving groove 231, and the head shield 202 is located in the head receiving groove 231. The front end of the encapsulated support plate 45 also has several second protrusions, with head clearance grooves 233 formed between adjacent second protrusions. A second shielding spring clearance groove 232 is also provided on the mounting surface of the second protrusions. When the head shielding spring 211 is compressed, it can be pressed into the second shielding spring clearance groove 232. The head is also provided with a slot, and the head molding has a locking block that mates with the slot. During installation, the head molding is installed on the molding support plate 45. At this time, the head shield 202 is located in the head receiving groove 231, while the head shield spring 211 protrudes from the second shield spring clearance groove 232. After the plug 2 and socket 1 are inserted, the head shield spring 211 is squeezed, and the second shield spring clearance groove 232 provides space for the head shield spring 211 to be squeezed.

[0027] In this embodiment, as Figure 11 As shown, several core wires 33 are also installed inside the plastic-sealed tail plate 46. The core wires 33 are connected to the corresponding head signal differential pairs 204. After the core wires 33 are connected to the head signal differential pairs 204, the core wires 33 are sealed inside the plastic-sealed tail plate 46.

[0028] In this embodiment, as Figure 15As shown, the partition plate 35 divides the installation window into an upper installation window 37 and a lower installation window 36. The head terminal module is installed in the installation window, and the upper plastic-encapsulated support plate 45 is located in the upper installation window 37, the lower plastic-encapsulated support plate 45 is located in the lower installation window 36, and the plastic-encapsulated tail plate 46 is located in the tail window of the installation window. In order to facilitate the installation of the plastic-encapsulated support plate 45, mounting slots 30 are provided on the left and right sides of the upper installation window 37 and the lower installation window 36. The left and right sides of the plastic-encapsulated support plate 45 are locked in the corresponding mounting slots 30, thereby realizing the installation of the plastic-encapsulated support plate 45 and the head base 31.

[0029] In this embodiment, as Figure 3 As shown, the socket 1 includes a housing 14, a base 13 is installed inside the housing 14, a mating groove 22 is formed inside the base 13, and a terminal module is installed inside the mating groove 22. In this embodiment, as shown... Figure 4 As shown, the socket terminal module includes a socket encapsulation body 11. A socket signal transmission module 12 is mounted on both the upper and lower surfaces of the socket encapsulation body 11, and the two socket signal transmission modules 12 are symmetrically arranged about the socket encapsulation body 11. In this embodiment, as shown... Figure 5 As shown, the base signal transmission module 12 includes a base molding compound 101, on which several base signal differential pairs 103 and base grounding springs 102 are molded. A set of base signal differential pairs 103 is located between every two base grounding springs 102. A base shielding assembly is also installed on the base molding compound 101, such as... Figure 6 As shown, the seat shielding assembly includes a long seat shield 104 and a short seat shield 105. The short seat shield 105 is located above the long seat shield 104, and the left and right sides of the short seat shield 105 are in contact with the upper surface of the corresponding seat grounding spring 102. The left and right sides of the long shield are in contact with the lower surface of the corresponding seat grounding spring 102. Each set of seat signal differential pairs 103 passes through the shielding cavity formed by the corresponding long seat shield 104 and short seat shield 105, thereby making the seat differential signal completely wrapped and shielded by the long seat shield 104 and short seat shield 105, thus effectively reducing the electromagnetic interference between the seat signal differential pairs 103 and improving the signal integrity of the entire transmission line.

[0030] In this embodiment, as Figure 6As shown, the short shield 105 includes a short shield plate 121. Second bends 124 are provided on both the left and right sides of the short shield plate 121, and these bends 124 bend towards the grounding spring 102. A second flange 122 is provided at the end of the second bend 124, and the second flange 122 contacts the corresponding grounding spring 102. Therefore, the short shield 105 has an Ω-shaped structure. The long shield 104 includes a long shield plate 111, and two spaced-apart shielding springs are provided at the rear end of the long shield plate 111. The front end of the base shield 111 of plate 112 is provided with first bending portions 115 on the left and right sides, and the first bending portions 115 bend towards the base grounding spring 102. The end of the first bending portion 115 is provided with a first flange 113, which contacts the corresponding base grounding spring 102. Therefore, the base shield 104 is also in the form of an Ω-shaped structure. The two Ω-shaped structures are coupled to each other to form a full-coverage shield, which effectively reduces the electromagnetic interference between the base signal differential pairs 103 and improves the signal integrity of the entire transmission line.

[0031] In this embodiment, as Figure 6 As shown, a first positioning boss 106 is installed on the upper surface of the seat molded enclosure 101. The first positioning boss 106 extends downward and passes through the lower surface of the seat molded enclosure 101. A first positioning notch 114 is provided on the first flange 113, and a second positioning notch 123 is provided on the second flange 122. The first positioning boss 106 is engaged in the corresponding first positioning notch 114, and the second positioning boss 106 is engaged in the corresponding second positioning notch 123. Furthermore, the first positioning boss 106 is a cylinder, and the first positioning notch 114 and the second positioning notch 123 are semi-circular notches. The first positioning notch 114 of the adjacent first flange 113 forms a circular hole that mates with the cylinder, and the second positioning notch 123 of the adjacent second flange 122 forms a circular hole that mates with the cylinder. Therefore, the seat shielding assembly and the seat molded enclosure 101 are positioned by the first positioning boss 106, thereby ensuring the reliability of the installation between the seat shielding assembly and the seat molded enclosure 101.

[0032] In this embodiment, as Figure 7As shown, the upper and lower surfaces of the seat encapsulation body 11 are provided with seat receiving grooves 131, and the seat shielding member 104 is located in the corresponding seat receiving groove 131. The rear end of the seat encapsulation body 11 is also provided with a plurality of first protrusions, and a seat positioning groove 134 is formed between adjacent first protrusions. A seat clearance groove 133 extending forward is also provided on the first protrusion. The upper and lower surfaces of the first protrusions are also provided with first shielding spring clearance grooves 132. When the seat shielding spring 112 is pressed, the seat shielding spring 112 can be pressed into the first shielding spring clearance groove 132. The upper and lower surfaces of the left and right ends of the seat encapsulation body 11 are also provided with positioning posts 135. The left and right ends of the seat encapsulation member 101 are provided with positioning holes 107 that cooperate with the positioning posts 135. The 35 is installed in the corresponding positioning hole 107. The positioning post 135 and the positioning hole 107 are used to achieve precise positioning and assembly between the seat plastic seal 101 and the seat plastic seal body 11. In this embodiment, eight sets of head signal differential pairs 204 and corresponding seat grounding springs 102 are installed on the seat plastic seal 101, so that the head signal differential pairs 204, seat grounding springs 102, seat shielding components and seat plastic seal body 11 form a whole. After the seat signal transmission module 12 is installed on both the upper and lower surfaces of the seat plastic seal body 11, the seat plastic seal body 11 and the seat signal transmission module 12 also form a whole. Therefore, the two signal transmission modules and the seat plastic seal body 11 form a whole seat terminal module, which is inserted into the insertion slot 22 of the socket 1.

[0033] In this embodiment, as Figure 8 As shown, two first stops 19 and two stops 20 are symmetrically arranged on the left and right side walls of the mating groove 22. A molding die positioning notch 21 is formed between adjacent first stops 19 and second stops 20. A molding die positioning notch 18 is formed between the two first stops 19. Forwardly extending notches are provided on both sides of the rear end face of the molding die, forming second positioning blocks 24. Rearwardly protruding first positioning blocks 23 are provided on both sides of the rear end face of the molding die 11. After the terminal block module is installed in the mating groove 22, the first positioning blocks 23 are engaged in the molding die positioning notch 18, and the second positioning blocks 24 are engaged in... The plastic molding component positioning notch 21 is located within the base 13, and the rear end face of the base plastic molding body 11 abuts against the first stop 19, while the rear end face of the base plastic molding component 101 abuts against the second stop 20. Therefore, when the base terminal module is installed with the base 13, the base terminal module is inserted into the mating groove 22. The base plastic molding body 11 is limited by the plastic molding component positioning notch 18, and the base plastic molding component 101 is limited by the plastic molding component positioning notch 21. The first stop 19 can block the base plastic molding body 11, and the second stop 20 can block the base plastic molding component 101, thereby ensuring the installation accuracy of the base terminal module and the base 13.

[0034] In this embodiment, as Figure 2As shown, the rear end face of the base 13 is provided with a flash 15, and the outer side wall of the front end face of the base 13 is provided with a backstop countersunk hole. The base housing 14 is provided with an inwardly expanding backstop spring 25. When the base housing 14 and the base 13 are installed, the rear end face of the base housing 14 abuts against the flash 15, and the front end face of the backstop spring 25 abuts against the front end of the backstop countersunk hole, thereby ensuring the reliability of the installation of the base 13 and the base housing 14.

[0035] In this embodiment, as Figure 16 As shown, the interlocking mechanism 34 includes an upper plate 241, an elastic bending part 243, and a lower plate 242. The upper plate 241 and the lower plate 242 are connected by the elastic bending part 243. The elastic bending part 243 has a stop-and-limit groove 245, and the lower plate 242 has a backstop hole 244. The upper plate 241 has an upwardly protruding locking block 246. The upper surface of the head base 31 has a protrusion with a locking groove 40. The front end of the locking groove 40 has a limiting boss 41, which is engaged in the stop-and-limit groove 245. The bottom of the locking groove 40 also has a backstop block located in the backstop hole 244. The left and right ends of the rear end of the locking groove 40 also have limiting plates 42, which are arranged opposite to each other. The upper plate 241 is pressed by the limiting plates 42. The base 13 has an interlocking notch 16, and the housing 14 has a clearance sidewall 28 with a locking hole 26. The locking block 246 is locked in the locking hole 26. When the plug 2 and the socket 1 are plugged in, the limiting boss 41 is stuck in the stop limiting groove 245, and the anti-reverse block is located in the anti-reverse hole 244. The locking block 246 is located in the locking hole 26. Without external force, the plug and socket 1 are interlocked and cannot be separated. When it is necessary to separate the plug 2 and the socket 1, the upper plate 241 is pressed to deform the elastic bending part 243, thereby causing the locking block 246 to disengage from the locking hole 26. Then, external force is applied to separate the plug 2 and the socket 1. Since the head base 31 has a protrusion, the base 13 has an interlocking notch 16 to facilitate the insertion of the protrusion.

[0036] In this embodiment, as Figure 7 As shown, a first concave-convex mechanism is provided on the rear end face of the seat seal 11. Specifically, the rear end of the seat seal 11 is also provided with a plurality of first protrusions, and a seat positioning groove 134 is formed between adjacent first protrusions. A seat clearance groove 133 extending forward is also provided on the first protrusion. The body of the first protrusion, the seat positioning groove 134, and the seat clearance groove 133 form the first concave-convex mechanism. A second concave-convex mechanism that cooperates with the first concave-convex mechanism is provided on the front end face of the partition plate 35. In this embodiment, as shown... Figure 15As shown, a first positioning protrusion 38 and a second positioning protrusion 39 are provided on the front end surface of the partition plate 35, and a positioning groove 43 is formed between the first positioning protrusion 38 and the second positioning protrusion 39. Therefore, the positioning groove 43, the first positioning protrusion 38 and the second positioning protrusion 39 on the partition plate 35 form a second concave-convex mechanism. During installation, the first positioning protrusion 38 is locked in the seat clearance groove 133, and the second positioning protrusion 39 is locked in the seat positioning groove 134. Therefore, through the cooperation of the first concave-convex mechanism and the second concave-convex mechanism, the reliability of the insertion of the head terminal module and the seat terminal module is ensured.

[0037] In this embodiment, as Figure 14 As shown, the front end of the plastic sealing plate 45 is also provided with several second protrusions, and a head relief groove 233 is formed between adjacent second protrusions. Several limiting blocks 27 are provided on the upper and lower inner walls of the insertion groove 22. When the plug 2 and the socket 1 are inserted, the first concave-convex mechanism cooperates with the second concave-convex mechanism, and the limiting block 27 is locked in the head relief groove 233. During the insertion process of the plug 2 and the base 13, the head terminal module can ensure the reliability of the installation of the plug 2 and the base 13 by cooperating with the limiting block 27 and the head relief groove 233.

[0038] The assembly process of this invention is as follows: The head signal differential pair 204 and the head grounding spring 203 are encapsulated on the head encapsulation body 20144. Then, the head shielding assembly is installed on the head encapsulation body 20144 to form the head signal transmission module 32. The head signal transmission module 32 is then installed on the corresponding head encapsulation body 20144 to form the head terminal module. The head terminal modules are then installed in the upper mounting window 37 and the lower mounting window 36, with the two head terminal modules arranged opposite each other. The head base 31 is installed onto the base 13. Due to the cooperation of the limiting block and the head clearance groove 233, the reliability of the installation of the plug 2 and the base 13 is ensured. Then, the socket terminal module is inserted into the base 13, while the socket terminal module is inserted through the mating cavity between the two head terminal modules. During insertion, the socket grounding spring 102 contacts the head grounding spring 203, and the socket signal differential pair 103 contacts the head signal differential pair 204. After the plug 2 and socket 1 are properly mated, as... Figure 17As shown, the head grounding spring 203 overlaps with the corresponding seat grounding spring 102, the head signal differential pair 204 overlaps with the corresponding seat signal differential pair 103, the seat shielding spring 112 contacts the third contact portion 221 of the corresponding head short shield 205, and the head shielding spring 211 contacts the seat short shield 105. Furthermore, the contact areas of the corresponding head grounding spring 203 and the seat grounding spring 102 form a parallelogram interlocking structure, and the corresponding head signal differential pair 204 and the seat signal differential pair 103 also form a parallelogram interlocking structure, thereby achieving effective signal transmission. Moreover, the seat signal differential pair 103 is fully enclosed by the seat shielding assembly. The differential signal pair 204 is fully shielded by the head shielding assembly, and the seat shielding spring 112 contacts the third contact portion 221 of the corresponding head short shield 205, while the head shielding spring 211 contacts the seat short shield 105. This achieves contact overlap between the seat shielding assembly and the head shielding assembly, thereby further ensuring the shielding performance of the differential signal pair. It can effectively shield the insertion portion of the differential signal pair, effectively reduce electromagnetic interference between differential signal pairs, improve the signal integrity of the entire transmission line, effectively solve the problem of unacceptable crosstalk at high speeds, significantly reduce signal crosstalk, and improve signal transmission quality.
