Description

Technical Field

[0001] This invention relates to the field of conductive connection device technology, and more specifically to a bent high-speed 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 these devices is also growing. As a result, the application of high-speed connectors that can transmit data at high speed is increasing. High-speed connectors mostly use Ethernet connectors that transmit differential signals.

[0003] Connectors are used to connect differential cables. To accommodate the vertical cable exit, a bend-type connector is generally used, where the cable exit direction is perpendicular to the connector insertion direction. The basic structure of this bend-type connector can be found in a corner RF connector disclosed in Chinese invention patent application CN117977269A, which includes an outer conductor, an insulator fixedly installed in the outer conductor, and an inner conductor fixedly installed in the insulator. The inner conductor includes a first section and a second section arranged at an angle. The insulator includes an integrally formed insertion section and a corner section. The insertion section of the insulator is used to insert into the insertion sleeve section of the outer conductor. The insulator is provided with an inner conductor mounting hole so that the first section of the inner conductor can be inserted from back to front. The corner section of the insulator is located at the rear end of the insertion section and is arranged at an angle to the insertion section. The corner section of the insulator has a mounting groove for receiving the second section of the inner conductor. The inner conductor forms the terminal. The first segment of the inner conductor forms the insertion segment, and the end of the first segment away from the second segment has a socket structure for insertion with the pins of the adapter connector to achieve signal conduction. The second segment of the inner conductor forms the wiring segment for crimping the wire core of the cable. The insulator forms the insulator for mounting the terminal, and the outer conductor forms the shielding shell for shielding the terminal.

[0004] The connector described above is used to transmit differential signals. Accordingly, two terminals are provided in pairs. The cable is a differential cable with two pairs of wire cores connected to the two terminals respectively. The corner section of the insulator has two parallel mounting grooves. After the two terminals are crimped with the cable, they are inserted into the insulator. The wiring sections of the two terminals are respectively inserted into the two mounting grooves. The mounting grooves on the insulator correspond one-to-one with the terminal mounting holes. Because the distance between the two terminals of the connector is greater than the distance between the two cores of the cable, the distance between the two cores of the cable will change to accommodate the terminals. The distance between the two cores is smaller where the cable is crimped and fixed with the shield, and larger where it is crimped and fixed with the terminals. The cable will bend at the point where the distance between the two cores changes. Since the terminal section is located inside the mounting groove of the insulator, the bending part of the two cores of the cable is outside the mounting groove to accommodate the distance between the two mounting grooves. However, the part where the shield is crimped and fixed with the cable is close to the insulator, so the space left for bending the cable cores is very limited. This requires the cores to have a relatively large bending angle. A large bending angle will cause a sudden change in the distance between the two cores, that is, a transition from small to large distance in a very short distance. The sudden change in the distance between the two cores will cause a large change in impedance at that point, which will adversely affect the high-speed transmission performance. Summary of the Invention

[0005] The purpose of this invention is to provide a bent high-speed connector to solve the problem that current bent high-speed connectors are prone to sudden changes in spacing due to large bending angles of the two wire cores of the cable when installing terminals and cables, which in turn affects transmission performance.

[0006] The technical solution of the bent high-speed connector of the present invention is as follows:

[0007] A high-speed bent connector includes an insulator and two terminals arranged in pairs. The insulator includes an insertion section and a corner section arranged at an angle. The terminals include an insertion section and a wiring section arranged at an angle. The insertion section has a mounting cavity for inserting the insertion section. The side of the corner section facing away from the connector insertion end has a receiving groove for receiving the wiring section. The wiring section is used to crimp the wire core of a cable. Two receiving grooves are provided corresponding to the terminals. The distance between adjacent groove walls of the two receiving grooves gradually decreases in the direction away from the mounting cavity. The wiring section is inclinedly arranged in the receiving groove, and the distance between the wiring sections at both ends gradually decreases in the direction away from the insertion section.

[0008] Beneficial Effects: This invention modifies the existing bent high-speed connector by making the adjacent groove walls of the two mounting grooves on the corner section of the insulator inclined. Furthermore, the distance between the adjacent groove walls gradually decreases in the direction away from the mounting cavity on the insulator insertion section; the further away from the mounting cavity, the closer the adjacent groove walls are. The inclined groove walls allow the terminal wiring segments to be inclinedly positioned within the grooves, and the distance between the terminal wiring segments gradually decreases in the direction away from the insertion section; the further away from the insertion section, the closer the distance between the terminal wiring segments is. The smaller the spacing between the connector segments, the more inclined the connector segments of the terminals are. Correspondingly, the wire cores of the cable that are crimped to the connector segments are also inclined. The spacing between the two wire cores of the cable and the part crimped to the terminal gradually increases, adapting to the change in the spacing between the two wire cores and the spacing between the two terminal insertion segments. The inclined connector segments of the terminals, in conjunction with the wire cores, facilitate the transition from the spacing between the two wire cores to the spacing between the two terminal insertion segments within the mounting groove. This helps to increase the length of the transition section of the wire cores, avoids large bending angles of the wire cores that would cause abrupt changes in spacing, and helps to improve impedance and ensure transmission performance.

[0009] Furthermore, the portion of the insulator located between the two mounting slots forms a guide boss, the adjacent slot walls of the two mounting slots constitute the two sides of the guide boss in the width direction, the width of the guide boss gradually decreases in the direction away from the mounting cavity, and the guide boss has a tip for extending between the outer insulating sheaths of the two wire cores.

[0010] Furthermore, the tip of the guide boss is located on the side of the end edge of the corner segment near the insertion segment.

[0011] Furthermore, the insulator is provided with a shielding shell, and the shielding shell is provided with a wire-bundling structure for binding the outer insulating sheath of the two core wires of the cable. The wire-bundling structure is located on the side of the corner section away from the insertion section, and the distance between the two core wires of the cable at the wire-bundling structure is smaller than the distance at the mounting groove.

[0012] Furthermore, the two oppositely spaced groove walls on the corner section are arranged in parallel.

[0013] Furthermore, one end of the back connector of the insulator is provided with a cover plate for covering the two mounting slots.

[0014] Furthermore, the portion of the insulator located between the two mounting slots is lower in the slot depth direction than the portions located on opposite sides of the two mounting slots, and the distance between the portions on opposite sides of the two mounting slots is not less than the width of the cover plate so that it can be embedded in the insulator when the cover plate covers the two mounting slots.

[0015] Furthermore, the cover plate is integrally mounted on the insulator, and the root of the cover plate connected to the main body of the insulator has a weak structure so as to cover the two mounting slots by bending.

[0016] Furthermore, the insulator is provided with a shielding structure, which includes a shielding baffle for limiting the cover plate to keep the cover plate in a state of covering the two mounting slots.

[0017] Furthermore, the insulator is provided with a shielding shell, which includes a corner shielding shell and a wire crimping shielding shell that are separately configured. The corner section of the insulator is located inside the corner shielding shell, and the wire crimping shielding shell is provided with a part for crimping the cable sheath.

[0051] The bent high-speed connector of the present invention utilizes the terminal wiring section to cooperate with the wire core in the mounting groove of the insulator to transition the distance between the two wire cores to the distance between the two terminal insertion sections. This can avoid the large bending angle of the wire core and the resulting sudden change in spacing, which is beneficial to improving impedance and ensuring transmission performance.

[0052] Embodiments of the bent high-speed connector of the present invention:

[0053] The bend-type high-speed connector includes an insulator and two pairs of terminals. The insulator includes an insertion section and a corner section arranged at an angle. The terminals include an insertion section and a wiring section arranged at an angle. The insertion section of the insulator has a mounting cavity for inserting the insertion section. The side of the corner section of the insulator facing away from the connector insertion end has a receiving groove for inserting the wiring section of the terminal. The wiring section of the terminal is used to crimp the wire core of the cable. There are two receiving grooves corresponding to the terminals. The distance between the adjacent groove walls of the two receiving grooves gradually decreases along the direction away from the mounting cavity. The adjacent groove walls of the two receiving grooves are inclined, so that the wiring section is inclined in the receiving groove. The distance between the wiring sections of the two terminals gradually decreases along the direction away from the insertion section. Correspondingly, the distance between the crimped portions of the two wire cores on the wiring section gradually increases along their extension direction to accommodate the larger distance between the insertion sections of the two terminals. This achieves a smooth transition from the distance between the two wire cores to the distance between the insertion sections of the two terminals, avoiding abrupt changes in distance that could affect the impedance of the link at that point.

[0054] Specifically, such as Figure 1 , Figure 2 As shown, the bent high-speed connector includes an insulating shell 1, a shielding structure, an insulator 8, and terminals 7. The shielding structure includes a shielding shell, a shielding baffle 5, and a shielding crimping 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. Two terminals 7 are provided, 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 1. The insulating shell 1 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.

[0055] This high-speed bend connector is a right-angle connector, with the insertion direction perpendicular to the outgoing wire direction. Figure 3 , Figure 4 , Figure 5 , Figure 6 , Figure 7 The connector's head and tail are oriented perpendicularly, with the head facing forward and the tail facing downward. The head is the mating end for interlocking with the adapter connector, and the tail is used to connect the cable 9. The wire-crimping shielding housing 2 has a connecting cavity 21, and the corner shielding housing 3 has a connecting end 31. The connecting end 31 is inserted into the connecting cavity 21 and fixed by crimping. The connecting cavity 21 has a crimping structure for crimping and fixing the connecting end 31, so that the wire-crimping shielding housing 2 and the corner shielding housing 3 are fixedly connected by crimping. The corner shielding housing 3 is located at the corner of the connector. The corner shielding housing 3 includes two mutually perpendicular parts, one part extending vertically and the other part extending front and back. The front end of the front and back extension 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. The orientation of the adapter end 32 is perpendicular to the orientation of the connecting end 31. The adapter end 32 faces forward while the connecting end 31 faces downward, so as to realize the vertical change of the head and tail of the bent high-speed connector.

[0056] 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 part that protrudes forward from the corner shield housing 3. This part is provided with a shielding connection structure for the shielding component 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, the contact shield housing 4 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 to make the corresponding parts of the corner shield housing 3 and the contact shield housing 4 concave and deformed to achieve a fixed connection.

[0057] When assembling the connector, first assemble the wire-crimping shielding shell 2, the corner shielding shell 3, and the contact shielding shell 4 into a single component, and then insert the insulator 8. Simultaneously, separately fabricate a wire, crimping the conductor core 91 of the cable 9 to the terminal 7. After bending the rear end of the terminal 7, insert it into the insulator 8. Insert the insulator 8 into the shielding shell, bend the tail cover of the insulator 8, insert the shielding baffle 5, and then crimp the wire-crimping shielding shell 2. Finally, install the entire assembly into the insulating shell 1. In other embodiments, an integrated shielding shell can also be used as needed.

[0058] Combination Figure 8 , Figure 9 , Figure 10 , Figure 11 , Figure 12 , Figure 13 , Figure 14 , Figure 15 The main body of terminal 7 is arranged in the front-to-back direction, and cable 9 is arranged in the 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 is provided with an inlet for inserting terminal 7 and insulator 8 into the corner shield housing 3. The inlet is open to the rear. Insulator 8 is inserted into corner shield housing 3 from back to front through the inlet and extends into contact shield housing 4. Terminal 7 is inserted into insulator 8 from back to front. The part of terminal 7 that connects to cable 9 is located at the rear of corner shield housing 3. Insulator 8 includes an insertion section 84 and a corner section 85 arranged at an angle. Insertion section 84 and corner section 85 are arranged perpendicularly to form a 90° angle. Insertion section 84 extends in the front-to-back direction and is inserted into the front of corner shield housing 3 and contact shield housing 4. Corner section 85 is located at the rear end of insertion section 84 and extends downward based on insertion section 84. Corner section 85 is inserted into the rear of corner shield housing 3. Terminal 7 includes an insertion section 72 and a wiring section 71 arranged at an angle. The insertion section 72 extends in the front-to-back direction and forms the main body of terminal 7. The wiring section 71 is located at the rear end of the insertion section 72 and bends downward. The end of the insertion section 72 away from the wiring section 71 has a mating structure, which is a socket structure for mating with a matching connector. The wiring section 71 is used to crimp the conductor core 91 of the cable 9. After the connector is assembled, the insertion section 72 and the wiring section 71 are arranged at an angle of 90°. In other embodiments, the angle between the insertion section and the corner section of the insulator can be 120° or 150°, etc., as needed, to accommodate bent connectors with different angles. Accordingly, the angle between the insertion section and the wiring section of the terminal is adjusted accordingly.

[0059] The insertion section 84 of the insulator 8 is provided with a mounting cavity for the insertion section 72 of the terminal 7 to be inserted. The mounting cavity is the terminal mounting hole 83, which is open from front to back. The rear side of the corner section 85 facing the connector insertion end is provided with a receiving groove 86 for the wire segment 71 to be inserted. There are two receiving grooves 86 corresponding to the terminal 7. There are two on the left and right sides of the terminal 7. There are two receiving grooves 86 on the left and right sides of the receiving groove 86. The receiving groove 86 is open from top to bottom and the groove opening faces backward. The receiving groove 86 corresponds one-to-one with the terminal mounting hole 83. The upper end of the receiving groove 86 is open to the terminal mounting hole 83. After the wire segment 71 of the terminal 7 is crimped and bent with the conductor core 91 of the cable 9, it is installed into the insulator 8. The part of the wire segment 71 and the conductor core 91 wrapped by the wire segment 71 are installed into the receiving groove 86 together.

[0060] Cable 9 is used to transmit differential signals. Cable 9 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 92 and a conductor core 91. The conductor cores 91 form the wire core. The two conductor cores 91 are used to transmit differential signals. The two conductor cores 91 are respectively connected to two terminals 7. The part of the conductor core 91 that is not crimped by the terminal segment 71 is wrapped by the insulating sheath 92. 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 on the outer sheath of cable 9. The shielding layer of cable 9 is turned outward and turned to the periphery of the shielding crimping ring 6. The shielding crimping ring 6 is inserted into the wire crimping shielding housing 2. The wire crimping shielding housing 2 clamps the shielding layer, and the two core wires extend into the corresponding receiving grooves 86 of the corner segment 85 of the insulator 8.

[0061] Each mounting slot 86 has two opposing side walls. The adjacent side walls of the two mounting slots 86 are inclined to form inclined side walls 87. The two mounting slots 86 are symmetrically arranged. The inclined side walls 87 of the two mounting slots 86 are V-shaped. The inclined side walls 87 of the two mounting slots 86 are opposite to each other and the distance between them gradually decreases in the direction away from the terminal mounting hole 83. That is, the distance between the adjacent side walls of the two mounting slots 86 gradually decreases from top to bottom. The wiring segment 71 of the terminal 7 is inclinedly arranged in the mounting slot 86, and the distance between the wiring segments 71 of the two terminals 7 gradually decreases in the direction away from the insertion segment 72. The distance between the wiring segments 71 of the two terminals 7 gradually decreases from top to bottom. Correspondingly, the conductor core 91 of the cable 9 is crimped with the wiring segment 71. The partial tilt setting of the conductor core in the figure is for illustrative purposes only and does not represent its actual usage state. After actual crimping, the conductor core within the insulation is tilted. The distance between the two conductor cores 91 of cable 9 and the crimped portion of terminal 7 gradually increases from bottom to top, adapting to the change in the distance between the two conductor cores of cable 9 below and the distance between the insertion sections 72 of the two terminals 7 above. The tilted connection section 71 of terminal 7, in conjunction with the conductor core, facilitates the transition from the distance between the two conductor cores to the distance between the insertion sections 72 of the two terminals 7 within the mounting groove 86. This helps to increase the length of the transition section of the conductor core and avoids abrupt changes in the distance caused by large bending angles of the conductor core. Adjusting the wire spacing and the angle of the two conductor cores helps to improve impedance and ensure transmission performance.

[0062] The portion of the insulator 8 located between the two mounting grooves 86 forms a guide boss 82. The adjacent groove walls of the two mounting grooves 86 constitute two side surfaces of the guide boss 82 in the width direction. These two side surfaces are also symmetrical inclined side walls 87. The width of the guide boss 82 gradually decreases in the direction away from the terminal mounting hole 83, that is, the width of the guide boss 82 gradually decreases from top to bottom in the left-right direction, so that the distance between the two conductor cores 91 of the cable 9 gradually increases from bottom to top. The lower end of the guide boss 82 is a pointed tip, which extends between the insulating sheaths 92 outside the two conductor cores 91. The insulating sheaths 92 have a portion that extends into the mounting groove 86. The pointed tip of the guide boss 82 limits the core wire of the cable 9 to facilitate the bending and deformation of the core wire of the cable 9. In other embodiments, the insulating sheath of the cable may not extend into the mounting groove, and the mounting groove only guides the tilting posture of the terminal connection segment.

[0063] The tip of the guide boss 82 is located on the side of the end edge of the corner segment 85 near the insertion segment 84, that is, the guide boss 82 is located above the lower end face of the corner segment 85. This allows the space below the guide boss 82 to facilitate the core wire of the cable 9 to extend into the receiving groove 86, avoiding excessive compression. In other embodiments, the lower end of the guide boss can also be flush with the lower end face of the corner segment.

[0064] The two mounting grooves 86 on the corner section 85 have their opposite groove walls arranged in parallel, so that the width of the mounting groove 86 gradually increases from top to bottom, which facilitates the insertion of the cable 9 and the wiring segment 71 of the terminal 7 into the mounting groove 86. In other embodiments, the opposite sides of the mounting groove can also be inclined and parallel to each other.

[0065] The connecting end 31 of the corner shielding shell is provided with a wire-binding structure for securing the insulating sheath 92 of the two cores of the cable 9. The wire-binding structure is located on the side of the corner section 85 away from the insertion section 84, that is, on the rear side of the connecting end 31. The wire-binding structure is a wire groove 35. The two cores of the cable 9 are inserted into the wire groove 35. The two cores of the cable 9 are secured within the wire groove 35 by crimping the shielding shell 2, thus securing the two cores of the cable 9. The spacing between the two cores of the cable 9 at the wire-binding structure is smaller than the spacing at the receiving groove 86. The wire-binding structure below the insulator 8 enhances the fixation of the cable 9. In other embodiments, the wire-binding structure may be omitted, and the cable may be fixed simply by crimping the cable sheath with the shielding shell.

[0066] Combination Figure 16 , Figure 17 One end of the insulator 8 facing the connector insertion end is provided with a cover plate for covering the two mounting slots 86. The cover plate is the insulating cover plate part 81. The two mounting slots 86 are covered by the same insulating cover plate part 81, which is simple in structure and convenient in operation. In other embodiments, the two mounting slots can also be provided with separate cover plates.

[0067] The portion of the insulator 8 located between the two mounting grooves 86 is lower in the groove depth direction than the portions located on opposite sides of the two mounting grooves 86. The distance between the portions on opposite sides of the two mounting grooves 86 is not less than the width of the insulating cover portion 81, with the width direction being left-right. The guide boss 82 is relatively low in height, allowing it to avoid the insulating cover portion 81, so that it can be embedded into the insulator 8 when the insulating cover portion 81 covers the two mounting grooves 86. In other embodiments, the portion of the insulator located between the two mounting grooves may also be flush with the portions located on opposite sides of the two mounting grooves.

[0068] An insulating cover plate 81 is integrally formed on the corner section 85 of the insulator 8. The corner section 85 and the insertion section 84 constitute the main body of the insulator 8. The root of the insulating cover plate 81, which is connected to the main body of the insulator 8, has a weak structure to facilitate bending and covering the two mounting slots 86. The thickness of the weak structure is small, making bending easy. After the terminal 7 and cable 9 are inserted into the insulator 8, the two mounting slots 86 are covered by bending the insulating cover plate 81, which can adjust the impedance. In other embodiments, the insulating cover plate may be omitted as needed.

[0069] Combination Figure 18 , Figure 19 , Figure 20 , Figure 21 To prevent the insulating cover plate 81 from rebounding after bending, the shielding baffle 5 can limit its movement. After being fixed to the shielding shell, the shielding baffle 5 is located on the rear side of the insulating cover plate 81 and is close to the insulating cover plate 81, which can keep the insulating cover plate 81 in the state of covering the two mounting grooves 86. In other embodiments, the insulating cover plate can also be bent and snapped onto the corner section without relying on the shielding baffle for limiting its movement.

[0070] Before the terminals 7 and cable 9 are installed, the insulating cover plate 81 extends straight backward. After the terminals 7 and cable 9 are installed, the insulating cover plate 81 can be bent downward to extend downward, covering the connection between the conductor core 91 of the terminals 7 and 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, keeping the cover plate in a state that covers the two mounting slots 86.

[0071] A shielding baffle 5 is installed over the rearward-facing entrance of the corner shielding housing 3 to ensure the shielding effect at the connection between the cable 9 and the terminal 7. The shielding baffle 5 includes a main body and a baffle crimping part 51 that extends downward from the main body. The rear of the corner shielding housing 3 is provided with a part for crimping and fixing the main body of the shielding baffle 5. The baffle crimping 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 crimping part 51 is fixed together with the connecting end 31 and the connecting cavity 21 by crimping. The crimping structure of the connecting cavity 21 includes two crimping petals 210 arranged opposite each other on the left and right. The two crimping petals 210 are used to close and deform during crimping and press the connecting end 31. After the end of the crimping petals 210 of the connecting cavity 21 is deformed, it is pressed onto the baffle crimping 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.

[0072] 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.

[0073] Both the wire-pressed shielding housing 2 and the contact shielding housing 4 are stamped parts, while the corner shielding housing 3 is a die-cast part. The split structure of the shielding housing facilitates processing and manufacturing. The connecting end 31 of the corner shielding housing 3 is provided with a rearward-facing wire groove 35, which runs vertically through and communicates with the mounting groove 86 of the insulator 8, allowing the cable 9 to extend vertically to the rear of the corner shielding housing 3. The two core wires of the cable 9 are respectively clamped in the wire groove 35 of the connecting end 31. The shielding crimping ring 6 is installed in the shielding crimping part 22 of the wire-pressed shielding housing 2, and 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 35 of the connecting end 31, and 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 by the crimping fixation of the connecting cavity 21.

[0074] Combination Figure 22 , Figure 23 The insulating outer shell 1 has snap-fit ​​spring arms 11 on its left and right side walls, with the snap-fit ​​spring arms 11 extending forward. The corner shielding shell 3 has snap-fit ​​bosses 33. When the corner shielding shell 3 is inserted into the insulating outer shell 1 from back to front, the snap-fit ​​spring arms 11 can snap onto the rear side of the snap-fit ​​bosses 33. On the front side of the snap-fit ​​bosses 33, the insulating outer shell 1 also has a rearward-facing stop surface 12. The snap-fit ​​spring arms 11 provide a rearward stop to the snap-fit ​​bosses 33, and the stop surface 12 provides a forward stop to the snap-fit ​​bosses 33, ensuring reliable assembly.
