[0019] The curved high-speed data connector of the present invention enables the separately arranged wire-pressing shielding shell and the corner shielding shell to form a stop-limit connection, and utilizes the limiting cooperation between the limiting protrusion and the limiting cavity to prevent the wire-pressing shielding shell and the corner shielding shell from being disengaged due to tension after being crimped and fixed, thereby ensuring a reliable fixed connection.

[0020] Embodiments of the curved high-speed data connector of the present invention: like Figure 1 , Figure 2 As shown, the curved high-speed data connector includes an insulating shell, a shielding structure, an insulator 8, and a terminal 7. The shielding structure includes a shielding shell, a shielding baffle 5, and a shielding crimping ring 6. The shielding shell includes a separately arranged crimping shielding shell 2, a corner shielding shell 3, and a contact shielding shell 4. Two terminals 7 are provided and form a differential pair to transmit differential signals. The terminal 7 is installed in the insulator 8, and the terminal 7 and the insulator 8 are integrally installed in the shielding shell, and the shielding shell is installed in the insulating shell. The insulating shell has a forward socket for the adapter connector to be inserted and form contact with the terminal 7 and the shielding shell to achieve signal conduction and shielding conduction.

[0021] Combination Figure 3 , Figure 4 , Figure 5The wire-pressing shielding shell 2 is provided with a connecting cavity 21, and the corner shielding shell 3 is provided with a connecting end 31. The connecting end 31 is inserted into the connecting cavity 21 and fixed by crimping. The connecting cavity 21 is provided with a crimping structure for crimping and fixing the connecting end 31, so that the wire-pressing shielding shell 2 and the corner shielding shell 3 are fixedly connected by crimping. In order to ensure a reliable fixed connection, the connecting end 31 is provided with a limiting protrusion, and the connecting cavity 21 is provided with a limiting cavity. The limiting protrusion is inserted into the limiting cavity to limit the connecting end 31 in the extension direction of the connecting cavity 21. After the connecting cavity 21 is crimped and fixed with the connecting end 31, the limiting cooperation between the limiting protrusion and the limiting cavity can make the connecting end 31 remain in the connecting cavity 21, so as to avoid the wire-pressing shielding shell 2 and the corner shielding shell 3 being detached due to tension after being crimped and fixed, which is beneficial to ensure a reliable fixed connection.

[0022] The curved high-speed data connector is a right-angle connector, and the head end and the tail end of the connector are oriented perpendicularly, which means that the head end of the connector faces forward and the tail end faces downward. The corner shielding shell 3 is arranged at the corner of the connector, and the corner shielding shell 3 includes two parts perpendicular to each other, one part extends up and down, and the other part extends forward and backward, wherein the front end of the front and rear extending parts is provided with a transfer end 32, and the transfer end 32 is used to connect to the contact shielding shell 4, and the connecting end 31 is arranged at the lower end of the upper and lower extending parts, and the direction of the transfer end 32 is perpendicular to the direction of the connecting end 31, and the transfer end 32 faces forward and the connecting end 31 faces downward, so as to realize the vertical change of the head end and the tail end of the curved high-speed data connector.

[0023] The crimping structure of the connecting cavity portion 21 includes two crimping flaps 210 arranged opposite to each other on the left and right. The two crimping flaps 210 are used to close, deform and press the connecting end portion 31 during crimping. The two crimping flaps 210 are respectively provided with a first groove 211, and the first groove 211 constitutes a limiting cavity. Correspondingly, the connecting end portion 31 is provided with a first convex portion 311 adapted to the first groove 211, and the first convex portion 311 constitutes a limiting convex portion. The two first grooves 211 and the two first convex portions 311 are used to form a limiting fit, and the force is uniform, which is conducive to reliable limiting.

[0024] The connecting cavity portion 21 includes a connecting portion connecting two crimped flaps 210. The two crimped flaps 210 are cantilever structures. The root of the cantilever is connected to the connecting portion, and the end of the cantilever is closed during crimping. A second groove 212 is provided on the connecting portion of the connecting cavity portion 21. The second groove 212 constitutes a limiting cavity. Correspondingly, a second protrusion 312 adapted to the second groove 212 is provided on the connecting end portion 31. The second protrusion 312 constitutes a limiting protrusion. The connecting portion of the connecting cavity portion 21 has a high structural strength. Setting a limiting matching structure at this position is beneficial to improving the stability of the limiting connection.

[0025] When the connecting end 31 is not crimped, the ends of the two crimping flaps 210 away from the connecting part form a side opening for the connecting end 31 to extend into the connecting cavity 21. When the crimping flaps 210 are not crimped, a larger side opening can be formed between the ends of the two crimping flaps 210, and the connecting end 31 can enter the connecting cavity 21 from the side opening, and the first protrusion 311 is snapped into the first groove 211, and the second protrusion 312 is snapped into the second groove 212. After being installed in place, the two crimping flaps 210 can be deformed by closing and deforming, and the ends of the two crimping flaps 210 are close to each other, and the crimping flaps 210 are deformed and pressed against the connecting end 31. The connecting cavity 21 is fixedly connected to the connecting end 31 by crimping, and cooperates with the limiting protrusion and the limiting cavity to realize axial and radial anti-detachment connection. After the first protrusion 311 is snapped into the first groove 211, it can realize the blocking and limiting in the front and rear directions. After the second protrusion 312 is snapped into the second groove 212, it can realize the blocking and limiting in the up and down directions.

[0026] The first protrusion 311 is provided with a guide surface for guiding the crimping flap 210 to expand and deform outward when the connecting end 31 extends into the connecting cavity 21 from the side opening. The guide surface is an inclined surface. Before the first protrusion 311 does not enter the first groove 211, the crimping flap 210 is guided to expand and deform outward to facilitate the loading operation. The protruding direction of the second protrusion 312 is opposite to the direction of the side opening when the connecting end 31 is loaded into the connecting cavity 21 from the side opening. The second protrusion 312 and the second groove 212 are directly opposite in the direction in which the connecting end 31 is loaded into the connecting cavity 21, so that the second protrusion 312 directly enters the second groove 212 during installation, which is convenient for installation. The first groove 211 and the second groove 212 are both through grooves that penetrate in the wall thickness direction of the connecting cavity 21. The first groove 211 and the second groove 212 are both rectangular grooves. The corresponding protrusions are adapted to the shapes of the grooves so that the limiting cavity has a side wall for cooperating with the limiting protrusion to stop rotation, which is conducive to ensuring the installation position of the crimping shielding shell 2 and the corner shielding shell 3. After the first protrusion 311 is inserted into the first groove 211, the rearward side surface of the first protrusion 311 and the front side wall of the first groove 211 form a front and rear stop fit perpendicular to the extension direction of the connecting cavity 21, and after the second protrusion 312 is inserted into the second groove 212, the upward side surface of the second protrusion 312 and the downward side wall of the second groove 212 form an upper and lower stop fit along the extension direction of the connecting cavity 21, wherein the corresponding protrusions and grooves form front and rear stop fits, and there may be a small gap in the upper and lower directions; and form upper and lower stop fits, and there may be a small gap in the left and right directions.

[0027] The contact shielding shell 4 is inserted into the corner shielding shell 3 from the adapter end 32, and the contact shielding shell 4 extends in the front-to-back direction. The contact shielding shell 4 has a portion protruding forward of the corner shielding shell 3 and the portion is provided with a shielding connection structure for contacting the shielding component of the adapter connector. The corner shielding shell 3 is provided with a riveting portion 34. After the contact shielding shell 4 is inserted into the corner shielding shell 3, the contact shielding shell 4 is fixed to the corner shielding shell 3 by riveting at the riveting portion 34. The riveting here adopts a rivet-free riveting process, that is, stamping is performed at the riveting portion 34, so that the corresponding portions of the corner shielding shell 3 and the contact shielding shell 4 are concave and deformed to achieve fixed connection. The contact shielding shell 4 is not subject to external force during actual use, and reliable fixation can be guaranteed.

[0028] Combination Figure 6 , Figure 7 , Figure 8 , Fig. 9 , Fig.10 , Fig.11 , Fig.12 The head end of the connector is a plug-in end for plugging with an adapter connector, and the tail end of the connector is used to connect the cable 9. The terminals 7 are arranged in the front-to-back direction, and the cables 9 are arranged in the up-down direction. The upper end of the cables 9 is crimped and fixed to the rear end of the terminals 7. The rear side of the corner shielding shell 3 away from the transfer end 32 is provided with a loading port for the terminals 7 and the insulator 8 to be loaded into the corner shielding shell 3, and the loading port is open to the rear. The insulator 8 is loaded into the corner shielding shell 3 from the back to the front through the loading port and extends into the contact shielding shell 4. The terminal 7 is loaded into the insulator 8 from the back to the front. The part where the rear end of the terminal 7 is connected to the cable 9 is at the rear of the corner shielding shell 3. In order to ensure the shielding effect, the shielding baffle 5 is covered at the loading port to ensure the shielding effect of the connection between the cable 9 and the terminal 7. The shielding is performed by using a separately arranged shielding baffle 5, which is conducive to simplifying the structure of the shielding shell and facilitating manufacturing.

[0029] The shielding baffle 5 includes a main body part and a baffle crimping portion 51 cantilevered downwardly based on the main body part. The rear part of the corner shielding shell 3 is provided with a portion for crimping and fixing the main body part of the shielding baffle 5. The baffle crimping portion 51 of the shielding baffle 5 extends to the rear side of the connecting end portion 31 and is located in the connecting cavity portion 21 when fixedly installed. The baffle crimping portion 51 constitutes the portion of the shielding baffle 5 that extends into the connecting cavity portion 21. The baffle crimping portion 51 is fixed together with the connecting end portion 31 and the connecting cavity portion 21 by crimping. The end of the crimping petal 210 of the connecting cavity portion 21 is deformed and pressed tightly on the baffle crimping portion 51, thereby ensuring that the shielding baffle 5 is reliably fixed. The baffle crimping portion 51 of the shielding baffle 5 is arranged to protrude inwardly toward the connecting end portion 31 relative to the main body portion, that is, it is staggered up and down relative to the main body portion. After the end of the crimping flap 210 of the connecting cavity portion 21 is deformed, it is pressed tightly against the rear side surface of the baffle crimping portion 51, which can prevent the crimping flap 210 from protruding too high backward after crimping, thereby saving space.

[0030] The wire crimping shielding shell 2 includes a shell crimping part, a shielding crimping part 22, and an outer skin crimping part 23 which are arranged in sequence from top to bottom. The shell crimping part, i.e., the connecting cavity part 21, is used to crimp the corner shielding shell 3, the shielding crimping part 22 is used to crimp the shielding layer of the cable 9, and the outer skin crimping part 23 is used to be crimped and fixed on the outer skin of the cable 9. The connecting cavity 21 of the crimping shielding shell 2 extends in the up and down direction. When the crimping flap 210 of the connecting cavity 21 is not crimped, the connecting end 31, the cable 9, and the baffle crimping portion 51 can enter from the rear opening of the connecting cavity 21. After the crimping flap 210 of the connecting cavity 21 is crimped, the portion of the crimping flap 210 located on the rear side of the connecting end 31 is bent and deformed, and the connecting end 31 and the baffle crimping portion 51 are tightly fixed. The crimping and fixing portion of the crimping flap 210 is on the side of the corner shielding shell 3 where an installation port is provided. The side opening of the wire crimping shielding shell 2 and the installation port of the corner shielding shell 3 are both arranged rearward, which is convenient for installation operation.

[0031] The wire crimping shielding shell 2 and the contact shielding shell 4 are both stamping parts, and the corner shielding shell 3 is a die-casting part. The shielding shell with a split structure is easy to process and manufacture. The cable 9 is crimped and fixed to the wire crimping shielding shell 2, and the corner shielding shell 3 is crimped and fixed to the corner shielding shell 3, and an anti-disengagement limit is formed through the limit cavity and the limit convex part to prevent the wire crimping shielding shell 2 from being disengaged from the corner shielding shell 3 due to the force on the cable 9.

[0032] Combination Fig.13 , Fig.14 , Fig.15 , Fig.16The connection end 31 of the corner shielding shell 3 is provided with a wire groove facing backwards, which is through from top to bottom and communicates with the loading port at the rear of the corner shielding shell 3, so that the cable 9 can extend to the rear of the corner shielding shell 3 in the up-down direction. The wire groove constitutes a space for the cable 9 to extend from the wire pressing shielding shell to the corner shielding shell. The cable 9 is used to transmit differential signals, including an outer sheath, a shielding layer, and a core wire. The outer sheath is an insulating rubber sheath. There are two core wires, each of which includes an insulating sheath and a conductor core 91. The two conductor cores 91 are used to transmit differential signals. The two conductor cores 91 are respectively connected to the two terminals 7, and the shielding layer is provided between the two core wires and the outer sheath. After the wire is made, the shielding crimping ring 6 is crimped and fixed on the outer skin of the cable 9, the shielding layer of the cable 9 is turned outward and turned to the periphery of the shielding crimping ring 6, the conductor core 91 of the cable 9 is crimped with the terminal 7, and then the terminal 7 and the cable 9 are installed on the shielding shell together, the terminal 7 is installed in the terminal installation hole 83 of the insulator 8, the two core wires of the cable 9 are respectively stuck in the wire groove of the connecting end 31, and the shielding crimping ring 6 is installed in the shielding crimping part 22 of the crimping shielding shell 2, and the shielding layer and the shielding crimping ring 6 of the cable 9 are crimped and fixed by the shielding crimping part 22. The baffle crimping part 51 of the shielding baffle 5 is blocked at the wire groove of the connecting end 31, and the baffle crimping part 51 of the shielding baffle 5 is pressed against the core wire of the cable 9 to keep the core wire in a fixed position through the crimping and fixing of the connecting cavity 21, which can play a role in adjusting the impedance.

[0033] The insulator 8 is provided with a rear side wall facing backwards, and the terminal mounting hole 83 extends in the front-to-back direction and passes through the rear side wall of the insulator 8. The center line of the terminal mounting hole 83 is perpendicular to the rear side wall of the insulator 8. The rear side wall of the insulator 8 is provided with a guide groove for the core wire of the cable 9 to be installed, and a guide boss 82 is formed between the two guide grooves. The two side surfaces of the guide boss 82 in the width direction are inclined surfaces, and the width direction is the left-right direction. The width of the guide boss 82 gradually increases from bottom to top, so that the distance between the two conductor cores 91 of the cable 9 gradually increases from bottom to top. The conductor core in the figure is only used to illustrate its approximate position. In fact, the conductor core 91 of the cable 9 is tilted in the guide groove, which is beneficial to improve the impedance at the connection between the terminal 7 and the conductor core 91 while adapting to the connection between the conductor core 91 and the terminal 7.

[0034] Combination Fig.17 , Fig.18 The rear end of the insulator 8 is also provided with a bendable insulating cover plate portion 81. Before the terminal 7 and the cable 9 are not installed, the insulating cover plate portion 81 is suspended straightly backward. After the terminal 7 and the cable 9 are installed, the insulating cover plate portion 81 can be bent downward to become a downwardly suspended state, which can cover the connection between the terminal 7 and the conductor core 91 of the cable 9, and play a role in adjusting the impedance. The insulating cover plate portion 81 is integrally formed with the main body of the insulator 8, which can reduce costs. After the shielding baffle 5 is installed, the shielding baffle 5 can limit the insulating cover plate portion 81 to keep the insulating cover plate portion 81 in a downwardly suspended state.

[0035] Combination Fig.19 , Fig. 20 A bendable terminal crimping portion 71 is provided at the rear end of the terminal 7. After the conductor core 91 of the cable 9 and the terminal crimping portion 71 of the terminal 7 are fixed together, the terminal 7 and the cable 9 are installed into the insulator 8 and the shielding shell. At this time, the terminal crimping portion 71 can be bent downward to adapt to the structural form of the right-angle connector. The terminal crimping portion 71 faces downward and is installed in the guide groove at the rear of the insulator 8, and the terminal crimping portions 71 of the two terminals 7 are arranged at an angle. The terminal crimping portion 71 is inclined in the guide groove to adapt to the extension angle of the two conductor cores 91.

[0036] Combination Fig.21 , Fig. 22 A snap-on elastic arm 11 is provided on the left and right side walls of the insulating shell, and the snap-on elastic arm 11 is cantilevered forward. A snap-on boss 33 is provided on the corner shielding shell 3. When the corner shielding shell 3 is inserted into the insulating shell from back to front, the snap-on elastic arm 11 can be snapped on the rear side of the snap-on boss 33. On the front side of the snap-on boss 33, a rearward stopping surface 12 is also provided on the insulating shell.
