Description
Technical Field
[0001] This invention relates to the field of conductive connection device technology, and more specifically to a bent high-speed data connector. Background Technology
[0002] As the level of intelligent driving in automobiles continues to improve, the number of intelligent network devices in vehicles is also gradually increasing, and the amount of data exchanged between various devices is also growing. As a result, the application of high-speed data connectors is also increasing. High-speed data connectors mostly use Ethernet connectors that transmit differential signals.
[0003] The basic structure of the aforementioned connector can be found in a connector disclosed in Chinese Utility Model Patent Document CN217281302U. This connector includes an insulating shell and a terminal assembly installed within the insulating shell. The structure of the terminal assembly is described in the second embodiment. The terminal assembly includes an insulator, terminals, a shielding shell, a cable, a crimping sleeve, and a support sleeve. This connector is a bendable connector, with its insulator being L-shaped, having a first insulator portion extending along a first direction and a second insulator portion extending along a second direction perpendicular to the first direction. The terminals are fixed within the insulator, and the shielding shell is L-shaped and installed within it. The cable, mounted on the outside of an insulator, is a differential signal cable for transmitting differential signals. The cable has two conductor cores and a shielding layer. The two conductor cores are electrically connected to two terminals respectively. The shielding shell is assembled from multiple shell components. The part where the terminal connects to the conductor core of the cable is located inside the second shell component. The second shell component has a shielding connection part located outside the shielding layer of the cable. A support cylinder is inserted into the shielding layer of the cable to support the shielding layer. The first crimping end of the crimping sleeve is fitted over the shielding connection part of the second shell component and the outside of the shielding layer and crimps the shielding layer onto the shielding connection part. The second crimping end of the crimping sleeve is used to crimp onto the outer surface of the cable.
[0004] The aforementioned high-speed bent data connector's shielding shell and crimping sleeve constitute the connector's shielding structure. The second shell component of the shielding shell and the crimping sleeve form two separately configured but fixedly connected shielding shells. The second shell component is located at the corner of the bent connector to form a corner shielding shell. The corner shielding shell has a cylindrical portion extending perpendicularly to the first shell component and a shielding connection portion. The cylindrical portion connects to the first shell component, and the shielding connection portion connects to the crimping sleeve. The crimping sleeve has a portion for crimping cables, forming a wire-crimping shielding shell. The second shell component and the crimping sleeve are fixedly connected by crimping. The crimping end of the crimping sleeve has two opposing crimping flaps. By pressing the two crimping flaps together and pressing them against the shielding connection portion of the second shell component, fixation is achieved. However, this structure relying on crimping for fixation is easily affected by the magnitude of the crimping force, leading to unreliable fixation. When the cable is subjected to significant tensile force, there is a risk that the two shell parts may detach. Summary of the Invention
[0005] The purpose of this invention is to provide a bent high-speed data connector to solve the problem that the current bent high-speed data connector, which connects two separate shielding shells by crimping, is prone to detachment when subjected to large tensile forces.
[0006] The technical solution of the bent high-speed data connector of the present invention is as follows:
[0007] A high-speed data connector with a bend includes a shielding structure. The shielding structure includes a corner shielding shell and a wire clamping shielding shell, which are separately arranged. One of the wire clamping shielding shell and the corner shielding shell has a connecting end, and the other has a connecting cavity for the connecting end to be inserted. The connecting end has a clearance space for the cable to extend from the wire clamping shielding shell to the corner shielding shell. The connecting cavity has a crimping structure for crimping and fixing the connecting end. One of the connecting end and the connecting cavity has a limiting protrusion, and the other has a limiting cavity for the limiting protrusion to be engaged to limit the connecting end in the extension direction of the connecting cavity.
[0008] Furthermore, the connecting cavity includes two opposing crimping flaps and a connecting portion connecting the two crimping flaps. The two crimping flaps constitute the crimping structure. The two crimping flaps are used to close and deform during crimping to press the connecting end. The crimping flaps and / or the connecting portion are provided with the limiting cavity.
[0009] Furthermore, at least one limiting cavity has a sidewall that engages with the corresponding limiting protrusion in the direction of extension of the connecting cavity, and at least one limiting cavity has a sidewall that engages with the corresponding limiting protrusion in the direction of extension perpendicular to the connecting cavity.
[0010] Furthermore, the ends of the two crimping flaps away from the connecting portion form a side opening for the connecting end to extend into when the connecting end is not crimped. The connecting end is provided with a first protrusion that matches the limiting cavity provided on the connecting portion and a second protrusion that matches the limiting cavity provided on the crimping flap. The first protrusion and the second protrusion respectively constitute a limiting protrusion. The first protrusion is provided with a guide surface that guides the crimping flap to expand outward when the connecting end extends into the connecting cavity from the side opening. The protrusion direction of the second protrusion is opposite to the orientation of the side opening when the connecting end extends into the connecting cavity from the side opening.
[0011] Furthermore, the wire-pressing shielding housing has a portion for pressing and fixing onto the cable sheath, and the corner shielding housing is used to shield the connection between the cable and the terminal. The connection end is provided on the corner shielding housing, and the corner shielding housing also has a transition end. The direction of the transition end is perpendicular to the direction of the connection end, and the extension direction of the connection cavity is consistent with the direction of the connection end.
[0012] Furthermore, the side of the corner shield housing away from the adapter end is provided with an inlet for inserting terminals and insulators, and the shielding structure includes a separately provided shielding baffle, which covers the inlet.
[0013] Furthermore, the shielding baffle is provided with a baffle pressing part for extending into the connecting cavity, and the baffle pressing part is fixed together with the connecting end and the connecting cavity by pressing.
[0014] Furthermore, the baffle pressing portion protrudes inward toward the connecting end relative to the main body portion of the shielding baffle.
[0015] Furthermore, the crimping structure of the connecting cavity is crimped and fixed to the side of the corner shield housing that has the loading inlet.
[0016] Furthermore, the pressure wire shielding shell is a stamped part, the corner shielding shell is a die-cast part, the connecting end is provided on the corner shielding shell, and the connecting cavity is provided on the pressure wire shielding shell.
[0017] Beneficial effects: This invention modifies the elements of the existing curved high-speed data connector, making the separate pressure shield housing and corner shield housing of the connector form a stop and limit connection. When the pressure shield housing and corner shield housing are connected to the connecting cavity through the connecting end, the connecting end is inserted into the connecting cavity, and the limiting protrusion is engaged with the limiting cavity to limit the connecting end in the extension direction of the connecting cavity. After the connecting end is pressed and fixed in the connecting cavity, the limiting cooperation between the limiting protrusion and the limiting cavity can keep the connecting end in the connecting cavity, avoiding the pressure shield housing and corner shield housing from separating due to tension after being pressed and fixed, which helps to ensure reliable fixed connection.

[0045] The present invention provides a curved high-speed data connector that forms a stop and limit connection between the separately configured pressure wire shielding shell and the corner shielding shell. The limiting cooperation between the limiting protrusion and the limiting cavity prevents the pressure wire shielding shell and the corner shielding shell from separating under tension after being pressed and fixed, thus ensuring a reliable fixed connection.
[0046] An embodiment of the bendable high-speed data connector of the present invention:
[0047] like Figure 1 , Figure 2As shown, the bendable high-speed data connector includes an insulating shell, a shielding structure, an insulator 8, and terminals 7. The shielding structure includes a shielding shell, a shielding baffle 5, and a shielding crimp ring 6. The shielding shell includes a separately configured wire-pressing shielding shell 2, a corner shielding shell 3, and a contact shielding shell 4. Terminals 7 are provided in pairs, forming a differential pair for transmitting differential signals. Terminals 7 are installed inside the insulator 8, and the terminals 7 and the insulator 8 are integrally installed inside the shielding shell. The shielding shell is installed inside the insulating shell, and the insulating shell has a forward-facing insertion port for the adapter connector to insert into and make contact with the terminals 7 and the shielding shell, achieving signal conduction and shielding conduction.
[0048] Combination Figure 3 , Figure 4 , Figure 5 The wire shielding housing 2 is provided with a connecting cavity 21, and the corner shielding housing 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 shielding housing 2 and the corner shielding housing 3 are fixedly connected by crimping. In order to ensure 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 along the connecting cavity 21. After the connecting cavity 21 crimps and fixes the connecting end 31, the limiting cooperation between the limiting protrusion and the limiting cavity can keep the connecting end 31 in the connecting cavity 21, preventing the wire shielding housing 2 and the corner shielding housing 3 from being separated by tension after crimping and fixing, which helps to ensure reliable fixed connection.
[0049] The bend-type high-speed data connector is a right-angle connector, with the head and tail ends of the connector facing perpendicularly, defined as the head end facing forward and the tail end facing downward. The corner shielding housing 3 is located at the corner of the connector. The corner shielding housing 3 includes two mutually perpendicular parts, one extending vertically and the other extending forward and backward. The front end of the forward and backward extension part is provided with an adapter end 32, which is used to connect to the contact shielding housing 4. The connecting end 31 is located at the lower end of the vertical extension part. The orientation of the adapter end 32 is perpendicular to the orientation of the connecting end 31, with the adapter end 32 facing forward and the connecting end 31 facing downward, so as to realize the vertical change of the head and tail ends of the bend-type high-speed data connector.
[0050] The crimping structure of the connecting cavity 21 includes two crimping flaps 210 arranged opposite each other on the left and right. The two crimping flaps 210 are used to close and deform during crimping and press the connecting end 31. The two crimping flaps 210 are respectively provided with a first groove 211, which constitutes a limiting cavity. Correspondingly, the connecting end 31 is provided with a first protrusion 311 that is adapted to the first groove 211. The first protrusion 311 constitutes a limiting protrusion. The two first grooves 211 and the two first protrusions 311 form a limiting fit, and the force is evenly distributed, which is conducive to reliable limiting.
[0051] The connecting cavity 21 includes a connecting portion that connects two crimping flaps 210. The two crimping flaps 210 are cantilever structures, with the root of the cantilever connected to the connecting portion. The ends of the cantilever close during crimping. The connecting portion of the connecting cavity 21 is provided with a second groove 212, which forms a limiting cavity. Correspondingly, the connecting end 31 is provided with a second protrusion 312 that matches the second groove 212, which forms a limiting protrusion. The connecting portion of the connecting cavity 21 has high structural strength. Using this part to set a limiting fit structure is beneficial to improving the stability of the limiting connection.
[0052] When the ends of the two crimping flaps 210 away from the connecting part are not crimped into the connecting end 31, they 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 large side opening can be formed between the ends of the two crimping flaps 210. The connecting end 31 can enter the connecting cavity 21 from the side opening, and the first protrusion 311 is engaged in the first groove 211, and the second protrusion 312 is engaged in the second groove 212. After being installed in place, the two crimping flaps 210 can be deformed by closing them together, and the ends of the two crimping flaps 210 are brought together. 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 the limiting protrusion and the limiting cavity are used to achieve axial and radial anti-detachment connection. After the first protrusion 311 is engaged in the first groove 211, it can achieve a stop and limit in the front and rear direction. After the second protrusion 312 is engaged in the second groove 212, it can achieve a stop and limit in the up and down direction.
[0053] The first protrusion 311 has a guide surface that guides the crimping flap 210 to expand outward when the connecting end 31 extends into the connecting cavity 21 from the side opening. The guide surface is inclined, guiding the crimping flap 210 to expand outward before the first protrusion 311 enters the first groove 211 to facilitate the installation operation. The protrusion direction of the second protrusion 312 is opposite to the orientation of the side opening when the connecting end 31 is inserted 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 inserted into the connecting cavity 21, so that the second protrusion 312 directly enters the second groove 212 during installation, which facilitates the installation operation. The first groove 211 and the second groove 212 are both through grooves that extend through the wall thickness direction of the connecting cavity 21. The first groove 211 and the second groove 212 are both rectangular grooves, and the corresponding protrusions and grooves are adapted to each other so that the limiting cavity has a side wall for anti-rotation engagement with the limiting protrusion, which is beneficial to ensuring the installation position of the wire shielding shell 2 and the corner shielding shell 3. After the first protrusion 311 is engaged with the first groove 211, the rearward side of the first protrusion 311 and the front sidewall of the first groove 211 form a front-rear stop fit perpendicular to the extension direction of the connecting cavity 21. After the second protrusion 312 is engaged with the second groove 212, the upper side of the second protrusion 312 and the lower sidewall of the second groove 212 form an upper-lower stop fit along the extension direction of the connecting cavity 21. At the front-rear stop fits formed by the corresponding protrusions and grooves, there may be a small gap in the vertical direction; at the upper-lower stop fits, there may be a small gap in the horizontal direction.
[0054] The contact shield housing 4 is inserted into the corner shield housing 3 from the adapter end 32. The contact shield housing 4 extends in the front-to-back direction and has a portion that protrudes forward from the corner shield housing 3. This portion is provided with a shielding connection structure for the shielding components of the adapter connector to contact. The corner shield housing 3 is provided with a riveting part 34. After the contact shield housing 4 is inserted into the corner shield housing 3, it is fixed to the corner shield housing 3 by riveting at the riveting part 34. The riveting here adopts a rivetless riveting process, that is, the riveting part 34 is stamped, so that the corresponding parts of the corner shield housing 3 and the contact shield housing 4 are concave and deformed to achieve a fixed connection. The contact shield housing 4 is not subjected to external force during actual use, which can ensure reliable fixation.
[0055] Combination Figure 6 , Figure 7 , Figure 8 , Figure 9 , Figure 10 , Figure 11 , Figure 12The connector's head end is a mating end for interlocking with a matching connector, and its tail end is for connecting cable 9. Terminals 7 are arranged in a front-to-back direction, and cable 9 is arranged in a vertical direction. The upper end of cable 9 is crimped and fixed to the rear end of terminal 7. The rear side of the corner shield housing 3, away from the adapter end 32, has an inlet for inserting terminals 7 and insulators 8 into the corner shield housing 3. The inlet is open to the rear. Insulator 8 is inserted into the corner shield housing 3 from back to front through the inlet and extends into the contact shield housing 4. Terminals 7 are inserted into the insulator 8 from back to front. The portion of terminal 7 that connects to cable 9 is located at the rear of the corner shield housing 3. To ensure shielding effectiveness, a shielding baffle 5 is placed over the inlet to ensure shielding at the connection point between cable 9 and terminal 7. Using a separately provided shielding baffle 5 simplifies the structure of the shield housing and facilitates manufacturing.
[0056] The shielding baffle 5 includes a main body and a baffle pressing part 51 that extends downward from the main body. The rear part of the corner shielding housing 3 is provided with a part for pressing and fixing the main body of the shielding baffle 5. The baffle pressing part 51 of the shielding baffle 5 extends to the rear side of the connecting end 31 and is located in the connecting cavity 21 during fixed installation. The baffle pressing part 51 constitutes the part of the shielding baffle 5 that extends into the connecting cavity 21. The baffle pressing part 51 is fixed together with the connecting end 31 and the connecting cavity 21 by pressing. After the end of the pressing petal 210 of the connecting cavity 21 is deformed, it is pressed against the baffle pressing part 51 to ensure that the shielding baffle 5 is reliably fixed. The baffle crimping part 51 of the shielding baffle 5 protrudes into the connection end 31 relative to the main body, that is, it is staggered vertically relative to the main body. After the end of the crimping petal 210 of the connection cavity 21 is deformed, it is pressed against the rear side of the baffle crimping part 51, which can prevent the crimping petal 210 from protruding too high after crimping and save space.
[0057] The wire-crimping shield housing 2 includes a housing crimping part, a shielding crimping part 22, and an outer sheath crimping part 23 arranged sequentially from top to bottom. The housing crimping part, i.e. the connecting cavity part 21, is used to crimp the corner shield housing 3. The shielding crimping part 22 is used to crimp the shielding layer of the cable 9. The outer sheath crimping part 23 is used to crimp and fix it to the outer sheath of the cable 9. The extension direction of the connecting cavity 21 of the wire shielding housing 2 is vertical. When the crimping flap 210 of the connecting cavity 21 is not crimped, the connecting end 31, the cable 9, and the baffle crimping part 51 can enter from the rearward opening of the connecting cavity 21. After the crimping flap 210 of the connecting cavity 21 is crimped, the part of the crimping flap 210 located behind the connecting end 31 bends and deforms, pressing and fixing the connecting end 31 and the baffle crimping part 51. The crimping and fixing part of the crimping flap 210 is on the side of the corner shielding housing 3 with the installation entrance. The side opening of the wire shielding housing 2 and the installation entrance of the corner shielding housing 3 are both set to face rearward, which facilitates the installation operation.
[0058] Both the wire clamping shield 2 and the contact shield 4 are stamped parts, while the corner shield 3 is a die-cast part. The split structure of the shield 3 facilitates processing and manufacturing. The cable 9 is clamped and fixed to the wire clamping shield 2, and the corner shield 3 is clamped and fixed to the corner shield 3. The corner shield 3 is clamped and fixed to the cable 9, and the clamping shield 2 and the corner shield 3 are prevented from separating due to the force exerted on the cable 9.
[0059] Combination Figure 13 , Figure 14 , Figure 15 , Figure 16 The connecting end 31 of the corner shield housing 3 is provided with a rearward-facing wire groove. The wire groove runs vertically through the corner shield housing 3 and communicates with the loading port at the rear of the corner shield housing 3, allowing the cable 9 to extend vertically to the rear of the corner shield housing 3. The wire groove forms a clearance space at the connecting end for the cable to extend from the wire-pressing shield housing to the corner shield housing. The cable 9 is used to transmit differential signals and includes an outer sheath, a shielding layer, and core wires. 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 and are respectively connected to two terminals 7. The shielding layer is located between the two core wires and the outer sheath. After the cable is made, the shielding crimping ring 6 is crimped and fixed onto the outer sheath of the cable 9. The shielding layer of the cable 9 is folded outward and onto the periphery of the shielding crimping ring 6. The conductor core 91 of the cable 9 is crimped with the terminal 7. Then, the terminal 7 and the cable 9 are installed together onto the shielding shell. The terminal 7 is inserted into the terminal mounting hole 83 of the insulator 8. The two core wires of the cable 9 are respectively clamped into the wire groove of the connecting end 31. The shielding crimping ring 6 is installed into the shielding crimping part 22 of the wire crimping shielding shell 2. The shielding layer of the cable 9 and the shielding crimping ring 6 are crimped and fixed by the shielding crimping part 22. The baffle crimping part 51 of the shielding baffle 5 blocks the wire groove of the connecting end 31. The baffle crimping part 51 of the shielding baffle 5 presses the core wire of the cable 9 to maintain the fixed position of the core wire through the crimping fixation of the connecting cavity 21, which can play a role in adjusting the impedance.
[0060] The insulator 8 has a rearward-facing rear sidewall. The terminal mounting hole 83 extends along the front-rear direction and penetrates the rear sidewall of the insulator 8. The center line of the terminal mounting hole 83 is perpendicular to the rear sidewall of the insulator 8. The rear sidewall of the insulator 8 has a guide groove for inserting the core wire of the cable 9. A guide boss 82 is formed between the two guide grooves. The two sides of the guide boss 82 in the width direction are inclined, and the width direction is left and right. 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 for illustrative purposes. In fact, the conductor core 91 of the cable 9 is inclined in the guide groove, which is beneficial to adapt to the connection between the conductor core 91 and the terminal 7 and improve the impedance at the connection between the terminal 7 and the conductor core 91.
[0061] Combination Figure 17 , Figure 18 The insulator 8 also has a bendable insulating cover plate 81 at its rear end. Before the terminal 7 and cable 9 are installed, the insulating cover plate 81 extends straight backward. After the terminal 7 and cable 9 are installed, the insulating cover plate 81 can be bent downward to extend downward, covering the connection between the terminal 7 and the conductor core 91 of the cable 9, thus adjusting the impedance. The insulating cover plate 81 is integrally formed with the main body of the insulator 8, which reduces costs. After the shielding baffle 5 is installed, the shielding baffle 5 can limit the insulating cover plate 81 to maintain its downward extension state.
[0062] Combination Figure 19 , Figure 20 The terminal 7 has a bendable terminal crimping part 71 at its rear end. After the conductor core 91 of the cable 9 is fixed together with the terminal crimping part 71 of the terminal 7, the terminal 7 and the cable 9 are installed into the insulator 8 and the shielding housing. At this time, the terminal crimping part 71 can be bent downward to adapt to the structure of the right angle connector. The terminal crimping part 71 faces downward and is installed into the guide groove at the rear of the insulator 8, and the terminal crimping parts 71 of the two terminals 7 are set at an angle. The terminal crimping part 71 is set at an angle in the guide groove to adapt to the extension angle of the two conductor cores 91.
[0063] Combination Figure 21 , Figure 22 The insulating shell has snap-fit spring arms 11 on its left and right side walls, which extend forward. The corner shield shell 3 has snap-fit protrusions 33. When the corner shield shell 3 is installed into the insulating shell from back to front, the snap-fit spring arms 11 can snap onto the rear side of the snap-fit protrusions 33. On the front side of the snap-fit protrusions 33, the insulating shell also has a rearward stop surface 12. The snap-fit spring arms 11 stop the snap-fit protrusions 33 backward, and the stop surface 12 stops the snap-fit protrusions 33 forward, ensuring reliable assembly.
[0064] During installation, first assemble the wire-pressing shield housing 2, the corner shield housing 3, and the contact shield housing 4 into a single component, and then insert the insulator 8. At the same time, make a separate wire, and crimp the conductor core 91 of the cable 9 to the terminal 7. Bend the rear end of the terminal 7 and insert it into the insulator 8. Bend the tail cover of the insulator 8 and insert the shielding baffle 5. Then crimp the wire-pressing shield housing 2. Finally, insert the whole assembly into the insulating shell.
[0065] In other embodiments, a connecting cavity may be provided at the lower end of the corner shielding housing, and a connecting end extending into the connecting cavity may be provided at the upper end of the wire-pressing shielding housing.
[0066] In other embodiments, the limiting protrusion may also be provided in the connecting cavity, and correspondingly, the limiting cavity is provided in the connecting end. The limiting protrusion may be a bulge structure formed by stamping.
[0067] In other embodiments, a limiting cavity may be provided only on the crimping flap or only on the connecting portion.
[0068] In other embodiments, the connecting end can also be inserted from the upward opening of the connecting cavity. In this case, each limiting protrusion is provided with an inclined downward guide surface so that the connecting end can be inserted into the connecting cavity from the top.
[0069] In other embodiments, the shielding baffle can also be integrally formed with the wire clamping shield housing. In this case, the side opening of the connecting cavity of the wire clamping shield housing faces forward, and the wire clamping shield housing is fixed to the connecting cable and the corner shield housing after the insulator is installed in the terminal.
