Description

Technical Field

[0001] This invention relates to the field of high-speed connector technology, and in particular to a high-speed cable assembly and connector. Background Technology

[0002] In high-speed cable assemblies, a shielding structure is used to shield the high-speed cable and the contacts connected to the high-speed cable. In order to ensure that the shielding structure can meet the requirements of high-speed performance and achieve sufficient shielding, and to better shield and isolate adjacent high-speed signal contact pairs and avoid crosstalk between adjacent differential pairs, existing high-speed cable assemblies mostly use a fully enclosed shielding structure to achieve sufficient shielding.

[0003] A high-speed cable assembly, as disclosed in Chinese invention patent application CN115084947A, includes a shielded cable assembly and a shielding buckle plate. The shielded cable assembly includes a high-speed cable, a shielding shell, and contact elements. The shielding shell is riveted to the high-speed cable, resulting in stronger connection stability and stable shielding conductivity. The shielding shell surrounds the contact elements and the parts of the contact elements that contact the high-speed cable on three sides. After the shielding buckle plate is fastened, a fully enclosed shielding structure is formed. The shielding buckle plate is connected to the shielding shell by welding, thereby limiting and fixing the shielding buckle plate in a direction perpendicular to the plate surface. The shielding buckle plate and each shielding shell form a shielding cavity at the front end of the high-speed cable assembly. The contact end of the contact element is suspended and disposed within the shielding cavity, resulting in good shielding effect.

[0004] Although this high-speed cable assembly can achieve full-enclosure shielding for each shielded cable assembly, the assembly process is relatively complex because the shielding structure is fixed in the high-speed cable assembly by riveting and welding. Furthermore, the lack of interconnection between the shielding structures at the plug-in ends of the high-speed cable assembly results in poor grounding shielding at the plug-in ends. Summary of the Invention

[0005] The purpose of this invention is to provide a high-speed cable assembly that solves the problems of complex assembly processes and poor grounding shielding at the mating ends in existing high-speed cable assemblies. Simultaneously, this invention provides a connector using the aforementioned high-speed cable assembly.

[0006] To achieve the above objectives, the high-speed cable assembly of the present invention adopts the following technical solution: A high-speed cable assembly includes an insulator with multiple contacts arranged along its width. The portions of the contacts extending out of the insulator form mating ends, and the other ends are connected to a differential cable. A shielding structure is provided on the outside of the insulator. The shielding structure includes a front shielding cylinder that is inserted and fixed to the front end of the insulator corresponding to the contacts. The front shielding cylinder includes a base plate and upright plates connected to both sides of the base plate. The ends of the upright plates have inwardly folded edges. The folded edges of the two upright plates are spliced ​​together to form the top plate of the front shielding cylinder. The front shielding cylinder provides shielding protection for the mating ends. A limiting structure is provided on the insulator to prevent the front shielding cylinder from coming out of the mating ends after insertion.

[0007] Furthermore, mounting seams are provided on both sides of each contact on the insulator, and the front shielding cylinder is inserted and fixed in the mounting seam.

[0008] Furthermore, the mounting seam has inward-facing fixing blocks on both sides for clamping the upright plate.

[0011] Furthermore, the front shielding cylinder has a side protrusion on the outer side of one of the upright plates.

[0012] Furthermore, the base plate is provided with an outward-facing bottom spring piece. When multiple high-speed cable assemblies are stacked, the bottom spring piece can contact the front protrusion provided on the outer side of the top plate of the front shielding cylinder in the adjacent row of high-speed cable assemblies, so as to realize common ground conduction between the front shielding cylinders of the adjacent rows of high-speed cable assemblies.

[0013] Furthermore, the high-speed cable assembly has a shielding plate on the same side as the base plate of the front shielding cylinder.

[0014] Furthermore, the shielding plate on the same side is provided with a groove-shaped grounding claw facing the insulator. The grounding claw contacts and clamps the grounding layer of the differential cable.

[0015] Furthermore, the shielding sheet on the same side is provided with positioning holes for positioning with the insulator.

[0016] Furthermore, the high-speed cable assembly also has a shielding plate on the opposite side of the base plate of the front shielding cylinder.

[0018] Furthermore, the opposite shielding plate is provided with positioning holes for positioning with the insulator.

[0019] Furthermore, the insulator has an injection-molded filler at the rear end of the shielding sheet on the same side.

[0020] Beneficial Effects: This invention provides an improved high-speed cable assembly, including a shielding structure comprising a front shielding cylinder disposed at the front end of an insulator. Compared to existing high-speed cable assemblies that use welding and riveting to assemble the shielding structure, the front shielding cylinder in this invention is cylindrical, inserted and fixed to the insulator, and a limiting structure is provided on the insulator to prevent the front shielding cylinder from detaching from the insertion end after insertion. The welding process is omitted during assembly, ensuring sufficient shielding while simplifying the assembly process.

[0021] The connector of this invention adopts the following technical solution: A connector includes a housing and a cable harness. A high-speed cable assembly is arranged side-by-side inside the housing. The high-speed cable assembly includes an insulator with multiple contacts arranged along its width. The portions of the contacts extending out of the insulator form mating ends, and the other ends are connected to differential cables. A shielding structure is provided on the outside of the insulator. The shielding structure includes a front shielding cylinder, which is inserted and fixed to the front end of the insulator corresponding to the contacts. The front shielding cylinder includes a base plate and upright plates connected to both sides of the base plate. The ends of the upright plates have inwardly folded edges. The folded edges of the two upright plates are joined to form the top plate of the front shielding cylinder. The front shielding cylinder provides shielding protection for the mating ends. A limiting structure is provided on the insulator to prevent the front shielding cylinder from dislodging from the mating ends after insertion.

[0022] Furthermore, mounting seams are provided on both sides of each contact on the insulator, and the front shielding cylinder is inserted and fixed in the mounting seam.

[0024] Furthermore, the front shielding cylinder has outward-facing wedge-shaped side protrusions on both side uprights, and a limiting groove is provided in the mounting seam to limit the wedge-shaped side protrusions. The limiting groove constitutes the limiting structure.

[0025] Furthermore, the two upright panels are joined and spliced ​​with interlocking edges.

[0026] Furthermore, the front shielding cylinder has a side protrusion on the outer side of one of the upright plates.

[0027] Furthermore, the base plate is provided with an outward-facing bottom spring piece. When multiple high-speed cable assemblies are stacked, the bottom spring piece can contact the front protrusion provided on the outer side of the top plate of the front shielding cylinder in the adjacent row of high-speed cable assemblies, so as to realize common ground conduction between the front shielding cylinders of the adjacent rows of high-speed cable assemblies.

[0028] Furthermore, the high-speed cable assembly has a shielding plate on the same side as the base plate of the front shielding cylinder.

[0029] Furthermore, the shielding plate on the same side is provided with a groove-shaped grounding claw facing the insulator. The grounding claw contacts and clamps the grounding layer of the differential cable.

[0030] Furthermore, the shielding sheet on the same side is provided with positioning holes for positioning with the insulator.

[0032] Furthermore, the opposite shielding plate is provided with a groove-shaped grounding claw facing the insulator. The grounding claw contacts and clamps the grounding layer of the differential cable.

[0033] Furthermore, the opposite shielding plate is provided with positioning holes for positioning with the insulator.

[0038] The features and performance of the present invention will be further described in detail below with reference to embodiments.

[0039] The inventive concept of this invention is as follows: Existing high-speed cable assemblies require riveting and welding for their shielding structure assembly, resulting in a cumbersome assembly process and impacting overall production efficiency. This invention provides a high-speed cable assembly that uses a cylindrical front shielding cylinder to form the shielding structure at the insertion end, thereby simplifying the assembly process, improving production efficiency, and ensuring product quality reliability.

[0040] As a basic technical solution, the high-speed cable assembly of the present invention includes an insulator, and a shielding structure is riveted to the outside of the insulator. The shielding structure includes a front shielding cylinder, which is formed by a base plate and upright plates with inward folded edges at the ends connected to both sides of the base plate. This eliminates the welding process, saves time and effort, improves the assembly efficiency of the high-speed cable assembly, and ensures the quality and reliability of the product.

[0041] Based on the above main concepts, the following embodiments are provided for illustration.

[0042] like Figure 1 As shown, the connector in this embodiment includes a housing 2 and a cable harness 3, wherein multiple sets of high-speed cable assemblies 1 are arranged side by side in the housing 2. Figure 13-15 As shown, the high-speed cable assembly 1 includes an insulator 11. Multiple contacts 10 are provided within the insulator 11 along its width. The portion of each contact 10 extending out of the insulator 11 forms a mating end, and the other end connects to a differential cable 15. A solder pad 101 is provided on the end of the contact 10 within the insulator 11. The solder pad 101 is connected to the signal line 151 of the differential cable 15 by welding, adhesive bonding, or other methods. The outside of the solder joint is coated with UV adhesive or other adhesives to prevent salt spray corrosion. A cable bundle position 113 is provided on the insulator 11 of the high-speed cable assembly 1 for placing the differential cable 15. The high-speed cable assembly 1 also has an injection molding position 114 for injection molding the differential cable 15 onto the high-speed cable assembly 1. After injection molding, an injection-molded filler 16 is formed on the insulator 13, behind the rear end of the shielding sheet 13 on the same side, for fixing the differential cable 15.

[0043] like Figure 2-6 As shown, a shielding structure is riveted to the outside of the insulator 11. Specifically, the shielding structure is provided with rivet holes 4, and the insulator 11 is provided with rivet posts 111 that cooperate with the rivet holes 4 at corresponding positions. The high-speed cable assembly 1 is provided with groove-shaped fixing positions 112 on both sides in the width direction. The fixing positions 112 are used to fix the row of high-speed cable assemblies 1 on both sides when multiple high-speed cable assemblies 1 are stacked in the housing 2, with comb-shaped cable bundles 3 being installed in the fixing positions 112 of each high-speed cable assembly 1.

[0044] The shielding structure includes a front shielding cylinder 12 corresponding to the contact element 10 and inserted into the front end of the insulator 11. For ease of description, it is referred to as... Figure 10 From the perspective of the viewpoint, the front shielding cylinder 12 includes a base plate 6 and upright plates 7 connected to both sides of the base plate 6. The ends of the upright plates 7 are provided with inwardly oriented flanges 72. The flanges 72 of the two upright plates 7 are spliced ​​together to form the top plate of the front shielding cylinder 12, and the front shielding cylinder 12 provides shielding protection for the insertion end. In order to enhance the structural strength of the front shielding cylinder 12, the front shielding cylinder 12 is provided with riveting positions 123 at the connection between the base plate 6 and the upright plates 7 and at the bending points of the upright plates 7, so that the two upright plates 7 can be connected by riveting.

[0045] like Figure 7-10 As shown, in the prior art, the shielding structure has no contact between the U-shaped shielding pieces at the mating end, resulting in poor grounding shielding at the mating end due to the lack of a spring-loaded structure. Therefore, in this embodiment, the front shielding cylinder 12 has inward-facing grounding spring claws 121 on both side upright plates 7. The grounding spring claws 121 are formed by metal stamping extension from the surface of the upright plate 7 or by connecting another metal sheet to the upright plate 7. To avoid the grounding spring claws 121 undergoing elastic deformation under force during mating with the male connector, the width direction, i.e., the arrangement direction of the U-shaped shielding pieces ( Figure 3 In one embodiment, the grounding spring claws 121 of adjacent front shielding cylinders 12 (in the direction of the medium-length arrow) touch. Figure 3 There is a certain misalignment in the direction of the short arrow (for clearance between adjacent front shielding cylinders 12). Additionally, to ensure that the male connector can be accurately inserted into the front shielding cylinder 12 and that the shielding cavity of the male connector does not come into contact with the inner wall of the front shielding cylinder 12, in one embodiment, the front shielding cylinder 12 has inwardly facing guide blocks 124 on both side uprights 7 at the front end of the grounding spring claw 121. The inward-facing surface of the guide block 124 is inclined, which guides the male connector during insertion, effectively preventing the shielding cavity of the male connector from contacting the front shielding cylinder 12.

[0046] The front shielding cylinder 12 is inserted into the front end of the insulator 11. Specifically, the insulator 11 has mounting slots 115 on both sides of each contact 10, and the front shielding cylinder 12 is inserted and fixed in the mounting slots 115. In order to further strengthen the connection between the front shielding cylinder 12 and the insulator 11, in one embodiment, fixing blocks 116 facing inward are provided on both sides of the mounting slots 115 for clamping the upright plate 7.

[0047] To eliminate the possibility of the front shielding cylinder 12 detaching from the mating end when the high-speed cable assembly 1 is mated with the male connector, the insulator 11 of the high-speed cable assembly 1 of the present invention is provided with a limiting structure to prevent the front shielding cylinder 12 from detaching from the mating end after insertion. In one embodiment, the front shielding cylinder 12 has outwardly facing wedge-shaped side protrusions 122 on both side upright plates 7, and a limiting groove 117 is provided in the mounting seam 115 to limit the wedge-shaped side protrusions 122. The limiting groove 117 constitutes the limiting structure. The limiting groove 117 is used to lock the wedge-shaped side protrusions 122 and provide a certain binding and holding force.

[0048] Since the front shielding cylinder 12 of the high-speed cable assembly 1 of the present invention is formed by a base plate 6 and upright plates 7 connected to both sides of the base plate 6, and the top plate of the front shielding cylinder 12 is formed by splicing the folded edges 72 of the two upright plates 7, considering that the top plate formed by splicing may detach when the shielding cavity of the male connector is inserted into the front shielding cylinder 12, in a more preferred embodiment, the folded edges 72 of the two upright plates 7 are interlocked. Specifically, dovetail protrusions and dovetail grooves are respectively provided on the folded edges 72 of the two upright plates 7. After the dovetail protrusions and dovetail grooves are aligned, they are riveted to form a riveting line 71 at the splicing point. This structure ensures that the top plate of the front shielding cylinder 12 formed by splicing is not easy to detach in the horizontal direction, and strengthens the structural stability of the front shielding cylinder 12 body.

[0049] To ensure that the distance between adjacent front shielding cylinders 12 does not get too close while they are in contact and conducting, in one embodiment, the front shielding cylinder 12 is provided with a side protrusion 125 on the outside of one side upright plate 7. The side protrusion 125 ensures that the adjacent front shielding cylinders 12 always maintain an appropriate distance.

[0050] Since the high-speed cable assembly 1 in the connector of the present invention is stacked in the housing 2, in order to ensure the overall shielding effect of the connector, in one embodiment, the base plate 6 is provided with a bottom spring piece 126 facing outward. When multiple high-speed cable assemblies 1 are stacked, the bottom spring piece 126 contacts the front protrusion 127 provided on the outer side of the top plate of the front shielding cylinder 12 in the adjacent row of high-speed cable assemblies 1, so as to realize common ground conduction between the front shielding cylinders 12 of the adjacent row of high-speed cable assemblies 1.

[0051] The shielding structure provided in the high-speed cable assembly 1 of the present invention can achieve full-enclosure shielding. Therefore, in addition to shielding and protecting the insertion end of the high-speed cable assembly 1, the shielding structure also shields and protects the two sides of the high-speed cable assembly 1 near the rear end. Specifically, as shown... Figure 11 As shown, the high-speed cable assembly 1 has a shielding plate 13 on the same side as the base plate 6 of the front shielding cylinder 12. The shielding plate 13 is also grounded to the differential cable 15. The differential cable 15 includes a pair of signal lines 151 arranged side-by-side. Each signal line 151 is wrapped with an insulating layer 152, and the insulating layer 152 is subsequently covered with a grounding layer 153 and an outer sheath 154. In one embodiment, the shielding plate 13 has a groove-shaped grounding claw 8 facing the insulator 11. The surfaces of the grounding claw 8 corresponding to the bottom and side surfaces of the U-shape are gold-plated. A certain amount of compression exists between the claws of the grounding claw 8, and the grounding claw 8 contacts and clamps the grounding layer 153 of the differential cable 15. The shielding plate 13 has rivet holes 4, which are used to connect with rivet posts 111 on the insulator 11.

[0052] To facilitate the installation of the same-side shielding plate 13, in a preferred embodiment, the same-side shielding plate 13 is provided with positioning holes 5 for positioning with the insulator 11, which facilitates alignment during installation. The same-side shielding plate 13 is provided with a grounding block 9, which is used to connect the same-side shielding plate 13 and the front shielding cylinder 12 to ground after assembly and covering them.

[0053] like Figure 12 As shown, in order to better achieve full-enclosure shielding of the high-speed cable assembly 1, in a preferred embodiment, the high-speed cable assembly 1 is further provided with a counter-shielding plate 14 on the opposite side of the base plate 6 of the front shielding cylinder 12. The same-side shielding plate 13 and the counter-side shielding plate 14 are used in conjunction to achieve shielding protection on both sides of the high-speed cable assembly 1. Similarly, the counter-side shielding plate 14 is provided with a groove-shaped grounding claw 8 facing the insulator 11. The surfaces of the grounding claw 8 corresponding to the bottom and side surfaces of the U-shape are gold-plated. There is a certain amount of compression between the claws of the grounding claw 8. The grounding claw 8 contacts and clamps the grounding layer 153 of the differential cable 15. The opposite shielding plate 14 is provided with a grounding block 9, which is used to assemble the back cover onto the front shielding cylinder 12 to achieve grounding connection between the opposite shielding plate 14 and the front shielding cylinder 12. The opposite shielding plate 14 is connected to the rivet post 111 provided on the insulator 11 through the rivet hole 4. In order to facilitate the installation of the opposite shielding plate 14, in a more preferred embodiment, the opposite shielding plate 14 is provided with a positioning hole 5 for positioning with the insulator 11, which facilitates alignment when installing the opposite shielding plate 14.

[0054] The present invention also provides a high-speed cable assembly 1, the embodiment of which has the same structure as the high-speed cable assembly 1 in the connector described above, and will not be described again here.

[0055] The above description is merely a preferred embodiment of the present invention and is not intended to limit the present invention. The scope of patent protection of the present invention shall be determined by the claims. Similarly, any equivalent structural changes made based on the description and drawings of the present invention shall also be included within the scope of protection of the present invention.
