Description

Technical Field

[0001] This invention relates to the field of conductive connection device technology, and more specifically to a bent 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, angled connectors are generally used, where the cable exit direction is perpendicular to the connector insertion direction. The basic structure of this type of connector can be found in Chinese invention patent application CN117977269A, which discloses an angled radio frequency connector. This connector 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 segment and a second segment arranged at an angle. The insulator includes an integrally formed insertion segment and an angled segment. The insertion section is used for insertion into the outer conductor. The insertion section has an inner conductor mounting hole for inserting the first segment of the inner conductor from back to front. A corner section is located at the rear end of the insertion section and is angled relative to it. The corner section has a mounting groove for receiving the second segment of the inner conductor. A cover arm is integrally connected to the rear end of the insertion section, extending away from the insertion direction to allow the rear end opening of the inner conductor mounting hole to pass. The cover arm can be bent relative to the insertion section and, after bending, covers and closes the mounting groove opening, thus sealing the second segment of the inner conductor within the mounting groove. The inner conductor constitutes a terminal. The first segment of the inner conductor constitutes the insertion section, 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 constitutes a wiring section for crimping the wire core of the cable. An insulator constitutes the insulator for mounting the terminal, the cover arm constitutes the cover of the insulator for covering the mounting groove, and the outer conductor constitutes a shielding shell for shielding the terminal. This connector 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.

[0004] After the terminal section is inserted into the mounting slot, the cover arm is bent downwards to cover the mounting slot. Then, the cover arm is pressed tightly against the rear side wall of the shielding shell to prevent it from tilting backwards. However, during the current bending operation of the cover arm, the bending position of the cover arm may deviate. The crease may appear closer to the root or farther away from the root. The position of the cover arm after bending may also deviate, and the cover arm may protrude slightly backwards or downwards from the set position. This will interfere with the shielding shell and affect the assembly of the shielding shell. When the shielding shell cannot be installed properly due to the interference of the cover arm, it is necessary to readjust the bending state of the cover arm, which is quite troublesome. Summary of the Invention

[0005] The purpose of this invention is to provide a bent connector to solve the problem that the cover of the current bent connector, which covers the mounting groove, is prone to positional deviation after bending, which affects the convenience of assembly operation.

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

[0007] A bent connector includes an insulator and terminals. The insulator includes an insertion section and a corner section arranged at an angle. The insertion section has a terminal mounting cavity into which a terminal insertion section is inserted. The side of the corner section facing away from the connector insertion end has a receiving groove into which a terminal wiring section is inserted. The insulator has a cover at the junction of the corner section and the insertion section. The cover has an open state in which it extends away from the connector insertion end to allow the terminal mounting cavity to pass, and a covered state in which it bends towards the end of the corner section to cover the receiving groove. The cover has a limiting fit structure, and the insulator has a limiting structure. The limiting structure and the limiting fit structure are in a limiting fit in the extension direction of the cover when the cover is in the covered state.

[0008] Beneficial effects: This invention improves upon existing bent connectors by incorporating a limiting fit structure on the insulator cover. When the cover is bent to cover the mounting groove, the limiting fit structure on the cover and the limiting structure on the insulator can form a limiting fit in the overhang direction of the cover. When the cover is bent to the point where the limiting fit structure and the limiting structure form a limiting fit, it indicates that the bending is complete. At the same time, the cover will not be over-bent under the limiting action. During the bending operation, it is easy to form the set bending state of the cover, making it easier to control the position of the cover after bending and avoiding positional deviation of the cover after bending that would affect the assembly of other connector components, thus facilitating the assembly operation.

[0009] Furthermore, the cover is provided with a limiting fitting protrusion protruding to one side in its width direction, the limiting fitting protrusion forming a limiting fitting structure, the limiting structure being a limiting surface adapted to the limiting fitting protrusion.

[0010] Furthermore, the limiting convex part is an arc-shaped convex part, and the limiting surface is an arc surface adapted to the arc-shaped convex part.

[0011] Furthermore, the cover includes a portion for covering the terminal mounting cavity when in a covered state and a portion for covering the mounting groove, wherein the portion of the cover covering the terminal mounting cavity includes the limiting engagement protrusion.

[0012] Furthermore, two terminals are provided in pairs, two mounting slots are provided corresponding to the terminals, and the cover is a cover plate, which covers both mounting slots when it is in the covering state.

[0013] 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 so that it can be embedded between the portions of the insulator located on opposite sides of the two mounting slots when the cover is in a covered state.

[0014] Furthermore, the root of the cover connected to the insertion segment has a weak structure to facilitate covering the mounting groove by bending.

[0015] Furthermore, the cover includes a main body segment and a thinning segment arranged along its overhang direction, the thickness of the thinning segment being less than the thickness of the main body segment, and the thinning segment constituting the weak structure.

[0016] Furthermore, the width of the thinned segment is smaller than the width of the main body segment.

[0017] Furthermore, the insulator is provided with a shielding structure, which includes a shielding baffle for limiting the cover to prevent the cover from warping. Attached Figure Description

[0048] When the cover of the bent connector of the present invention is bent to the state of covering the mounting groove, the limiting fit structure of the cover and the limiting structure on the insulator can form a limiting fit in the overhang direction of the cover, which restricts the bending state of the cover, makes it easier to control the position of the cover after bending, and avoids the position deviation of the cover after bending from affecting the assembly of other components of the connector.

[0049] Embodiments of the bent connector of the present invention:

[0050] The bent connector includes an insulator and terminals. The insulator includes an insertion section and a corner section arranged at an angle. The insertion section has a terminal mounting cavity into which the insertion section of the terminal is inserted. The side of the corner section facing away from the connector insertion end has a receiving groove into which the wiring section of the terminal is inserted. The insulator has a cover at the junction of the corner section and the insertion section. The cover has an open state in which it extends away from the connector insertion end to allow the terminal mounting cavity to pass, and a covered state in which it bends towards the end of the corner section to cover the receiving groove. The cover has a limiting fit structure. The insulator has a limiting structure. The limiting structure and the limiting fit structure limit each other in the direction of the cover's extension when the cover is in the covered state. When the cover is bent to the point where it abuts against the limiting structure, it indicates that the bend is in place. At the same time, the cover will not bend excessively under the limiting action. When the cover is bent, it is easy to form the set bending state, which makes it easy to control the position of the cover after bending and avoids the position deviation of the cover after bending affecting the assembly of other components of the connector, thus facilitating the assembly operation.

[0051] Specifically, such as Figure 1 , Figure 2 As shown, the bent 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 inserted into the shielding shell. The shielding shell is inserted into 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.

[0052] This bend-type connector is a right-angle connector, with the insertion direction perpendicular to the outgoing wire direction. Figure 3 , Figure 4 , Figure 5The connector's head and tail are perpendicular to each other, with the head facing forward and the tail facing downward. The head is the insertion end for mating with the adapter connector, and the tail is for connecting 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 to fix 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 and includes two mutually perpendicular parts: one part extends vertically and the other part extends forward and backward. The front end of the forward and backward extended part has 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 vertically extended 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 of the bent connector.

[0053] The contact shielding housing 4 is inserted into the corner shielding housing 3 from the adapter end 32. The contact shielding housing 4 extends in the front-to-back direction and has a portion that protrudes forward from the corner shielding housing 3. This portion is provided with a shielding connection structure for the shielding components of the adapter connector to contact. The corner shielding housing 3 is provided with a riveting part 34. After the contact shielding housing 4 is inserted into the corner shielding housing 3, it is fixed to the corner shielding 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 shielding housing 3 and the contact shielding housing 4 are recessed and deformed to achieve a fixed connection. The corner shielding housing 3 is provided with a snap-fit ​​boss 33. When the corner shielding housing 3 is inserted into the insulating shell 1 from back to front, it can engage with the snap-fit ​​spring arm on the inner wall of the insulating shell 1 through the snap-fit ​​boss 33.

[0054] Combination Figure 6 , Figure 7 , Figure 8 When assembling the connector, first assemble the wire-crimping shield housing 2, the corner shield housing 3, and the contact shield housing 4 into a component, and then insert the insulator 8. At the same time, make a separate wire, 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, insert the insulator 8 into the shield housing, bend the tail cover of the insulator 8, insert the shield baffle 5, then crimp the wire-crimping shield housing 2, and finally insert the whole assembly into the insulating shell 1.

[0055] Combination Figure 8 , Figure 9 , Figure 10 , Figure 11 , Figure 12 , Figure 13 , Figure 14, Figure 15 , Figure 16 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.

[0056] The insulator 8 includes an insertion section 84 and a corner section 85 arranged at an angle. The insertion section 84 and the corner section 85 are arranged perpendicularly to form a 90° angle. The insertion section 84 extends in the front-rear direction and is inserted into the front part of the corner shield housing 3 and into the contact shield housing 4. The corner section 85 is located at the rear end of the insertion section 84 and extends downward based on the insertion section 84. The corner section 85 is inserted into the rear part of the corner shield housing 3. The terminal 7 includes an insertion section 72 and a wiring section 71 arranged at an angle. The insertion section 72 extends in the front-rear direction and forms the main body of the 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 socket structure for insertion with a mating 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° as needed to accommodate bent connectors of different angles. Accordingly, the angle between the insertion section and the wiring section of the terminal is adjusted accordingly.

[0057] The insertion section 84 of the insulator 8 is provided with a terminal mounting cavity for the insertion section 72 of the terminal 7 to be inserted. The terminal mounting cavity is also known as the terminal mounting hole 83. The terminal mounting hole 83 is through the front and 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 through the top and bottom and the groove opening faces the rear. The receiving groove 86 corresponds one-to-one with the terminal mounting hole 83. The upper end of the receiving groove 86 is through 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.

[0058] 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.

[0059] Each mounting slot 86 has two opposite side walls, with the adjacent side walls of the two mounting slots 86 inclined to form inclined side walls 87. The portion of the insulator 8 located between the two mounting slots 86 forms a guide boss 82. The adjacent side walls of the two mounting slots 86 constitute the two sides of the guide boss 82 in the width direction. These two sides are also the left-right 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, and the width direction is the left-right direction. Two mounting slots 86 are symmetrically arranged on the left and right sides. The inclined sidewalls 87 of the two mounting slots 86 are V-shaped, which causes the wiring segments 71 of the terminals 7 to be inclinedly positioned within the mounting slots 86. The spacing between the wiring segments 71 of the two terminals 7 gradually decreases from top to bottom. Correspondingly, the portion of the conductor core 91 of the cable 9 that is crimped with the wiring segment 71 is inclined, and the spacing between the two conductor cores 91 of the cable 9 and the portion crimped with the terminal 7 gradually increases from bottom to top, adapting to the change in the spacing between the two conductor cores of the lower cable 9 and the spacing between the two insertion segments 72 of the upper terminals 7. The conductor core in the figure is only for illustrative purposes; in reality, the conductor core 91 of the cable 9 is inclined within the guide slot. The two mounting grooves 86 on the corner section 85 are arranged parallel to each other with their groove walls facing away from each other, so that the groove width of the mounting groove 86 gradually increases from top to bottom, which makes it easier to guide the cable 9 and the wiring segment 71 of the terminal 7 into the mounting groove 86. The wiring segment 71 of the terminal 7 is arranged at an angle in the guide groove so that the distance between the two conductor cores 91 of the cable 9 gradually changes.

[0060] One end of the back connector insertion terminal of the insulator 8 is integrally provided with a cover plate for covering the two receiving slots 86. The cover plate is the insulating cover plate 81, which constitutes a covering body. The insulating cover plate 81 is located at the junction of the corner section 85 and the insertion section 84 and is integrally connected to the rear end of the insertion section 84. Figure 17 , Figure 18The insulating cover 81 has an open state in which it extends backward toward the connector insertion end to allow the terminal mounting hole 83 to pass, and a covered state in which it is bent toward the end of the corner section 85 to cover the mounting groove 86. The corner section 85 extends downward based on the insertion section 84, and the lower end of the corner section 85 is its end. The insulating cover 81 can be bent from the rearward extension state to the downward extension state to cover the mounting groove 86 and the wiring section 71 within the mounting groove 86.

[0061] The insulating cover plate 81 is provided with a limiting engagement structure, and the insulator 8 is also provided with a limiting structure. When the cover plate is in the covered state, the limiting structure and the limiting engagement structure engage in a limiting engagement in the overhang direction of the cover plate. When the insulating cover plate 81 is bent until the limiting engagement structure abuts against the limiting structure, it indicates that the bending is in place. At the same time, under the limiting action, the insulating cover plate 81 will not be over-bent, limiting the degree of bending of the insulating cover plate 81. During the bending operation of the cover plate, it is easy to bend the cover plate to the set bending state, making it easier to control the position of the insulating cover plate 81 after bending, avoiding positional deviation of the insulating cover plate 81 after bending, which would affect the assembly of other connector components such as the shielding baffle, and facilitating the assembly operation.

[0062] The insulating cover plate 81 is oriented left-right in its width direction. It has a limiting engagement protrusion 813 protruding to one side in its width direction, forming a limiting engagement structure. The limiting structure on the insulator 8 is a limiting surface 88 located towards the root of the insulating cover plate 81. Both the left and right sides of the insulating cover plate 81 have limiting engagement protrusions 813, and correspondingly, the insulator 8 has two limiting surfaces 88. When the insulating cover plate 81 is bent into place, the limiting engagement protrusion 813 can abut downwards against the corresponding limiting surface 88, using the limiting surface 88 to limit the insulating cover plate 81 and prevent it from shifting downwards. Simultaneously, by having the limiting engagement protrusion 813 abut against the limiting surface 88, it is easy to determine whether the bending operation is complete. In other embodiments, a protruding post can be provided on the insulating cover plate, with the protruding post facing downward when the cover plate is in the open state. A rearward limiting hole is provided on the insulator. The position of the cover plate after bending is determined by inserting the protruding post into the limiting hole. The protruding post constitutes a limiting fit structure, and the limiting hole constitutes a limiting structure.

[0063] The limiting fitting protrusion 813 is an arc-shaped protrusion, and the opposite sides of the two arc-shaped protrusions are arc surfaces. Correspondingly, the limiting surface 88 is an arc surface adapted to the arc-shaped protrusion. The limiting fit is formed by the arc surface, which facilitates the downward limiting and lateral limiting of the insulating cover plate 81. In other embodiments, the limiting fitting protrusion can also be a square protrusion, and correspondingly, the limiting surface is an upward-facing plane.

[0064] The insulating cover plate 81 includes a portion for covering the rearward opening of the terminal mounting hole 83 when in a covered state, and a portion for covering the two receiving grooves 86. The portion of the insulating cover plate 81 covering the terminal mounting hole 83 includes a limiting fitting protrusion 813. That is, by using the portion of the insulating cover plate 81 with the limiting fitting protrusion 813 to cover the terminal mounting hole 83, the limiting function is ensured while reducing the size of the insulating cover plate 81. In other embodiments, the limiting fitting protrusion may also be provided on the portion of the insulating cover plate for covering the two receiving grooves, and correspondingly, a limiting groove is provided on the groove wall of the receiving groove for the limiting fitting protrusion to enter.

[0065] When the insulating cover plate 81 is in the covered state, it covers both receiving slots 86. Using the same insulating cover plate 81 to cover both receiving slots 86 results in a simple structure and convenient operation. In other embodiments, each of the two receiving slots may be equipped with a separate covering arm, and the covering arms constitute a cover.

[0066] 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 plate 81. This means the guide protrusion 82 is lower, allowing it to avoid the insulating cover plate 81. When the insulating cover plate 81 is in the covered state, it can be embedded between the portions of the insulator 8 located on opposite sides of the two mounting grooves 86, i.e., embedded between the oppositely spaced groove walls of the two mounting grooves 86. The limiting surface 88 is a concave arc surface, symmetrically arranged on both sides and respectively contacting the oppositely spaced groove walls of the two mounting grooves 86. The limiting surface 88 is located on the upper side of the corresponding groove wall surface of the mounting groove 86. The insulating cover plate 81 is embedded within the space of the mounting grooves 86, resulting in a compact structure and space saving. In other embodiments, the portion of the insulator located between the two mounting slots may be flush with the portions located on opposite sides of the two mounting slots, and the insulating cover plate may be bent and abutted against the rear side of the corner section.

[0067] The insulating cover plate 81 has a weak structure at its root where it connects to the insertion section 84, facilitating bending to cover the receiving groove 86. This weak structure facilitates bending and allows for better control of the bending deformation location on the insulating cover plate 81. The insulating cover plate 81 includes a main body section 812 and a thinning section 811 arranged along its overhang direction. The thickness of the thinning section 811 is less than the thickness of the main body section 812, forming a weak structure that is simple and easy to manufacture. The thinning section 811 connects to the insertion section 84, and a limiting fitting protrusion 813 is provided on the main body section 812 at the point where it connects to the thinning section 811. The width of the thinning section 811 is less than the width of the main body section 812, reducing its strength and facilitating bending. In other embodiments, a through hole can be provided at the root of the insulating cover plate to form a weak structure. In other embodiments, the width of the thinning section can be the same as the width of the main body section.

[0068] After the terminal 7 and cable 9 are installed inside the insulator 8, the two mounting slots 86 are covered by bending the insulating cover plate 81, which can adjust the impedance. Figure 19 , Figure 20 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 behind and 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 to prevent the cover plate from tilting up. In other embodiments, after the insulating cover plate is bent, the cover plate can also be fixed to the corner section by a pin, without relying on the shielding baffle of the shielding structure to limit the movement of the insulating cover plate.

[0069] 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 become a downward-extending state, which can cover the connection between the terminal 7 and the conductor core 91 of the cable 9.

[0070] 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.

[0071] 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.

[0072] 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, which runs vertically 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 of the connecting end 31. The shielding crimping ring 6 is installed in the shielding crimping part 22 of the wire-pressed shielding housing 22, 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 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.
