Description

Technical Field

[0001] The present invention relates to the technical field of high-speed connectors, and in particular to a high-speed cable assembly and a connector. Background Art

[0002] In a high-speed cable assembly, 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 wrapping of the shielding structure can meet the high-speed performance and achieve a sufficient shielding effect, and to better shield and isolate adjacent high-speed signal contact pairs to avoid crosstalk between adjacent differential pairs, existing high-speed cable assemblies mostly use a fully enclosed shielding structure to achieve a sufficient shielding effect.

[0003] For example, a high-speed cable assembly disclosed in a Chinese invention patent application with application publication number CN115084947A comprises a shielded cable assembly and a shielding buckle plate, wherein the shielded cable assembly comprises a high-speed cable, a shielding shell and a contact piece, the shielding shell is riveted to the high-speed cable, the connection stability is stronger, the shielding conduction performance is stable, the shielding shell surrounds the contact piece and the part where the contact piece contacts the high-speed cable on three sides, and a fully enclosed shielding structure is formed after the shielding buckle plate is buckled, and the shielding buckle plate is connected to the shielding shell by welding to limit and fix 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, and the contact end of the contact piece is cantilevered in the shielding cavity, so as to achieve a good shielding effect.

[0004] Although this high-speed cable assembly can achieve full shielding of each shielded cable assembly, during the assembly process of the shielding structure, since the shielding structure is fixed in the high-speed cable assembly by riveting and welding, the assembly process is relatively complicated, and the shielding structures at the plug-in ends of the high-speed cable assembly are not interconnected, resulting in poor grounding shielding effect at the plug-in ends. Summary of the invention

[0005] The purpose of the present invention is to provide a high-speed cable assembly to solve the problem that the existing high-speed cable assembly has a relatively complex assembly process and a relatively poor grounding shielding effect at the plug-in end. At the same time, the present invention provides a connector using the high-speed cable assembly.

[0006] To achieve the above objectives, the high-speed cable assembly of the present invention adopts the following technical solutions: A high-speed cable assembly includes an insulator. A plurality of contacts are arranged inside the insulator along the width direction. The portion of the contact extending out of the insulator constitutes a plug-in end, and the other end is connected to a differential cable. A shielding structure is arranged on the outside of the insulator. The shielding structure includes a front shielding cylinder corresponding to the contact and inserted and fixed at the front end of the insulator. The front shielding cylinder includes a bottom plate and vertical plates connected to both sides of the bottom plate. The ends of the vertical plates are provided with folded edges facing inward. The folded edges of the two vertical plates are spliced ​​to form the top plate of the front shielding cylinder. The front shielding cylinder shields the plug-in end. A limiting structure is arranged on the insulator to prevent the inserted front shielding cylinder from falling out of the plug-in end.

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

[0011] Furthermore, the front shielding tube is provided with a side convex package on the outer side of one side vertical plate.

[0012] Furthermore, a bottom spring sheet facing outward is provided on the bottom plate. When multiple high-speed cable assemblies are stacked, the bottom spring sheet can contact the front convex bump provided on the outer side of the top plate of the front shielding tube in the adjacent row of high-speed cable assemblies, thereby achieving common ground conduction between the front shielding tubes of the adjacent rows of high-speed cable assemblies.

[0013] Furthermore, the high-speed cable assembly is provided with a shielding sheet on the same side as the bottom plate of the front shielding cylinder.

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

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

[0018] Furthermore, a positioning hole for positioning with the insulator is provided on the opposite side shielding sheet.

[0019] Furthermore, the insulator is provided with an injection-molded filling body at the rear end of the shielding sheet on the same side.

[0020] Beneficial effects: The present invention provides an improved high-speed cable assembly, including a shielding structure, wherein the shielding structure includes a front shielding cylinder arranged at the front end of an insulator. Compared with the high-speed cable assembly in the prior art, which uses welding and riveting to complete the assembly of the shielding structure, the front shielding cylinder in the high-speed cable assembly of the present invention is cylindrical, plugged and fixed on the insulator, and a limiting structure is provided on the insulator to prevent the front shielding cylinder from falling out of the plug-in end after insertion. The shielding structure omits the welding process during assembly, ensuring that the fully enclosed shielding structure is used to achieve a sufficient shielding effect while simplifying the assembly process.

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

[0023] Furthermore, fixing blocks facing inwards are provided on both sides of the installation seam for clamping the vertical plates.

[0024] Furthermore, the front shielding tube is provided with wedge-shaped side clamping protrusions facing outwards on the vertical plates on both sides, and limiting grooves for limiting the wedge-shaped side clamping protrusions are provided in the installation seam, and the limiting grooves constitute the limiting structure.

[0025] Furthermore, the folded edges of the two vertical panels are spliced ​​and joined.

[0026] Furthermore, the front shielding tube is provided with a side convex package on the outer side of one side vertical plate.

[0027] Furthermore, a bottom spring sheet facing outward is provided on the bottom plate. When multiple high-speed cable assemblies are stacked, the bottom spring sheet can contact the front convex bump provided on the outer side of the top plate of the front shielding tube in the adjacent row of high-speed cable assemblies, thereby achieving common ground conduction between the front shielding tubes of the adjacent rows of high-speed cable assemblies.

[0028] Furthermore, the high-speed cable assembly is provided with a shielding sheet on the same side as the bottom plate of the front shielding cylinder.

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

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

[0038] The features and performance of the present invention are further described in detail below in conjunction with the embodiments.

[0039] The inventive concept of the present invention is as follows: In view of the fact that the existing high-speed cable assembly needs to adopt a riveting and welding assembly method when assembling its shielding structure, which makes the assembly process more cumbersome and affects the overall production efficiency, the present invention provides a high-speed cable assembly, which adopts a cylindrical front shielding cylinder to form a shielding structure at the plug-in end, thereby simplifying the assembly process, improving production efficiency, and ensuring the reliability of product quality.

[0040] As a basic technical solution, the high-speed cable assembly of the present invention includes an insulator, a shielding structure is riveted on the outside of the insulator, and the shielding structure includes a front shielding cylinder, which is surrounded by a base plate and vertical plates connected to both sides of the base plate and have inward folded edges at the ends. The welding process is omitted, which saves time and labor, 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, embodiments are provided below for illustration.

[0042] like Figure 1 As shown, the connector in the embodiment includes a housing 2 and a cable tie 3, wherein a plurality 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, and a plurality of contacts 10 are arranged in the insulator 11 along the width direction. The part of the contact 10 extending out of the insulator 11 constitutes the plug-in end, and the other end is connected to the differential cable 15. A soldering pad 101 is arranged on one end of the contact 10 in the insulator 11, and the soldering pad 101 is connected to the signal line 151 of the differential cable 15 by welding, gluing, etc., and an adhesive such as UV glue is coated on the outside of the soldering point to prevent salt spray corrosion. A wiring position 113 is arranged on the insulator 11 of the high-speed cable assembly 1 for placing the differential cable 15. An injection molding position 114 is also arranged on the high-speed cable assembly 1 for injection molding the differential cable 15 onto the high-speed cable assembly 1. After injection molding, an injection molding filler 16 is formed on the insulator 13 behind the rear end of the shielding sheet 13 on the same side, which is used to fix the differential cable 15.

[0043] like Figure 2-6 As shown, a shielding structure is riveted on the outside of the insulator 11. Specifically, a rivet hole 4 is provided on the shielding structure, and a rivet column 111 is provided at a corresponding position of the insulator 11 to cooperate with the rivet hole 4. 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 high-speed cable assemblies 1 in a row on both sides when multiple high-speed cable assemblies 1 are stacked in the housing 2. The comb-shaped cable ties 3 are clamped 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 10 and inserted at the front end of the insulator 11. Fig.10 From the perspective of the front shielding tube 12, the front shielding tube 12 includes a bottom plate 6 and vertical plates 7 connected to both sides of the bottom plate 6. The ends of the vertical plates 7 are provided with folded edges 72 facing inward. The folded edges 72 of the two vertical plates 7 are spliced ​​to form the top plate of the front shielding tube 12. The front shielding tube 12 shields the plug-in end. In order to enhance the structural strength of the front shielding tube 12 body, the front shielding tube 12 is provided with riveting positions 123 at the connection between the bottom plate 6 and the vertical plate 7 and at the bending of the vertical plate 7 body, and the vertical plates 7 on both sides are connected by riveting.

[0045] like Figure 7-10 As shown, the shielding structure in the prior art has no contact between the U-shaped shielding sheets at the plug-in end, so no spring sheet structure is provided, resulting in a poor grounding shielding effect at the plug-in end. Therefore, the front shielding cylinder 12 in this embodiment is provided with grounding spring claws 121 facing inward on the vertical plates 7 on both sides. The grounding spring claws 121 are formed by extending the metal stamping on the surface of the vertical plate 7 or by connecting another metal sheet to the vertical plate 7. In order to avoid elastic deformation of the grounding spring claws 121 when being subjected to force during the plugging process with the male end connector, the width direction, that is, the arrangement direction of the U-shaped shielding sheets ( Figure 3 In one embodiment, the grounding claws 121 of the front shielding tube 12 touch each other in the thickness direction (a direction perpendicular to the cable assembly plugging direction, i.e., the width direction mentioned above), and the grounding claws 121 of the adjacent front shielding tubes 12 touch each other. Figure 3 There is a certain misalignment in the direction of the middle and short arrows, which is used to avoid the adjacent front shielding tubes 12. In addition, in order to ensure that the male connector can be accurately inserted into the front shielding tube 12, and the shielding cavity of the male connector will not touch the inner wall of the front shielding tube 12, in one embodiment, the front shielding tube 12 is provided with an inward guide block 124 at the front end of the grounding claw 121 on the two side vertical plates 7. The inner surface of the guide block 124 is an inclined surface, which guides the male connector when it is inserted, and effectively avoids the male connector shielding cavity from touching the front shielding tube 12.

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

[0047] In order to eliminate the possibility that the front shielding tube 12 may fall out of the plug-in end when the plug-in end of the high-speed cable assembly 1 is plugged into the male connector, a limiting structure is provided on the insulator 11 of the high-speed cable assembly 1 of the present invention to prevent the front shielding tube 12 from falling out of the plug-in end after insertion. In one embodiment, the front shielding tube 12 is provided with a wedge-shaped side clamping protrusion 122 facing outward on the two side vertical plates 7, and a limiting groove 117 for limiting the wedge-shaped side clamping protrusion 122 is provided in the installation seam 115, and the limiting groove 117 constitutes the limiting structure. The limiting groove 117 is used to clamp the wedge-shaped side clamping protrusion 122 and provide a certain restraint and holding force.

[0048] Since the front shielding tube 12 of the high-speed cable assembly 1 of the present invention is surrounded by the bottom plate 6 and the vertical plates 7 connected to the two sides of the bottom plate 6, the folded edges 72 of the two vertical plates 7 are spliced ​​to form the top plate of the front shielding tube 12. Considering that the top plate formed by splicing when the shielding cavity of the male connector is inserted into the front shielding tube 12 may be detached, in a more preferred embodiment, the folded edges 72 of the two vertical plates 7 are spliced ​​together. Specifically, dovetail protrusions and dovetail grooves are respectively provided on the folded edges 72 of the vertical plates 7 on both sides, and the dovetail protrusions and dovetail grooves are aligned and riveted to form a riveting line 71 at the splicing. This structural setting ensures that the top plate of the spliced ​​front shielding tube 12 is not easy to detach in the horizontal direction, and strengthens the structural stability of the front shielding tube 12 body.

[0049] In order to ensure that the distance between adjacent front shielding tubes 12 arranged side by side is not too close while being in contact and conductive, in one embodiment, the front shielding tube 12 is provided with a side convex bump 125 on the outer side of a side vertical plate 7, and the side convex bump 125 ensures that an appropriate distance is always maintained between adjacent front shielding tubes 12.

[0050] Since the high-speed cable assembly 1 in the connector of the present invention is stacked and used in the housing 2, in order to ensure the overall shielding effect of the connector, in one embodiment, the bottom 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 convex bump 127 provided on the outer side of the top plate of the front shielding tube 12 in the adjacent row of high-speed cable assemblies 1, thereby achieving common ground conduction between the front shielding tubes 12 of the adjacent rows 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 the plug-in end of the high-speed cable assembly 1, the shielding structure also shields the two sides of the high-speed cable assembly 1 near the rear end. Specifically, Fig.11 As shown, the high-speed cable assembly 1 is provided with a same-side shielding sheet 13 on the same side as the bottom plate 6 of the front shielding tube 12. There is also a ground connection between the same-side shielding sheet 13 and the differential cable 15. The differential cable 15 includes a pair of signal lines 151 arranged side by side, and the signal lines 151 are wrapped with an insulating layer 152, and the insulating layer 152 is sequentially covered with a grounding layer 153 and an outer sheath 154. In one embodiment, the same-side shielding sheet 13 is provided with a groove-shaped grounding claw 8 facing the insulator 11, and the surface of the grounding claw 8 corresponding to the bottom and side surfaces of the U-shape is gold-plated. There is a certain amount of extrusion 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 same-side shielding sheet 13 is provided with a rivet hole 4, which is connected with the rivet column 111 provided on the insulator 11 through the rivet hole 4.

[0052] In order to facilitate the installation of the same-side shielding sheet 13, in a more preferred embodiment, the same-side shielding sheet 13 is provided with a positioning hole 5 for positioning with the insulator 11, so as to facilitate alignment when installing the same-side shielding sheet 13. The same-side shielding sheet 13 is provided with a grounding block 9, which is used to cover the front shielding tube 12 after assembly, so as to ground and conduct the same-side shielding sheet 13 with the front shielding tube 12.

[0053] like Fig.12 As shown, in order to better achieve full enclosure shielding of the high-speed cable assembly 1, in a more preferred embodiment, the high-speed cable assembly 1 is further provided with a contralateral shielding sheet 14 on the opposite side of the bottom plate 6 of the front shielding tube 12. The same-side shielding sheet 13 is used in conjunction with the contralateral shielding sheet 14 to achieve shielding protection on both sides of the high-speed cable assembly 1. Similarly, a groove-shaped grounding claw 8 facing the insulator 11 is provided on the contralateral shielding sheet 14, and the surface of the grounding claw 8 corresponding to the bottom and side surfaces of the U-shape is gold-plated, and there is a certain amount of extrusion 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. A grounding block 9 is provided on the opposite side shielding sheet 14, which is used to assemble the rear cover on the front shielding tube 12 to achieve grounding conduction between the opposite side shielding sheet 14 and the front shielding tube 12. The opposite side shielding sheet 14 is connected with the rivet column 111 set on the insulator 11 through the rivet hole 4. In order to facilitate the installation of the opposite side shielding sheet 14, in a more preferred embodiment, a positioning hole 5 for positioning with the insulator 11 is provided on the opposite side shielding sheet 14, which is convenient for alignment when the opposite side shielding sheet 14 is installed.

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