Abstract
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] For example, a high-speed cable assembly 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 and each shielding shell form a shielding cavity at the front end of the high-speed cable assembly. The contact tip of the contact element is suspended in 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 buckle and the shielding shell are fixed by welding. Furthermore, the lack of a spring clip structure at the plug end of the high-speed cable assembly results in poor grounding shielding at the plug end. 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:
[0007] A high-speed cable assembly includes an insulator with a contact element disposed within the insulator along its width. A portion of the contact element extending out of the insulator forms a mating end, and the other end is connected to a differential cable. A shielding structure is disposed on the outer side of the insulator. The shielding structure includes a U-shaped shielding plate corresponding to the contact element and a counter-shielding plate disposed on its opposite side. The U-shaped shielding plate includes a base plate and upright plates connected to both sides of the base plate. An extension portion extends along the base plate away from the mating end, forming a shielding structure at the rear end of the U-shaped shielding plate. The U-shaped shielding plate and the counter-shielding plate engage to form a shielding cavity, which provides shielding protection for the mating end. Adjacent upright plates of adjacent U-shaped shielding plates are clamped and fixed by double-plate clamps disposed on the counter-shielding plates. The double-plate clamps include jaws with opposite clamping directions to clamp the opposite sides of the corresponding upright plates.
[0008] Furthermore, the adjacent grippers of the double-plate clamp are staggered along the length of the U-shaped shielding sheet.
[0009] Furthermore, the opposite shielding sheet is provided with a group of single-plate clamps at both ends in its width direction for clamping the outer vertical plate of the U-shaped shielding sheet at the edge. The single-plate clamp includes clamping claws on both sides corresponding to the outer vertical plate.
[0010] Furthermore, the adjacent grippers of the single-plate clamp are staggered along the length of the U-shaped shielding sheet.
[0011] Furthermore, the ends of the grippers of the double-plate clamp have bent sections that bend outwards to guide the corresponding upright plates into the double-plate clamp.
[0012] Furthermore, the ends of the grippers of the single-plate clamp have bent sections that bend outwards to guide the corresponding upright plates into the single-plate clamp.
[0013] Furthermore, the two upright plates of the U-shaped shielding sheet have side protrusions on their outer sides.
[0014] Furthermore, the two convex bulges are respectively set at the diagonal points of the U-shaped shielding sheet.
[0015] Furthermore, mounting seams are provided on both sides of each contact on the insulator, and the top of the two vertical plates of the U-shaped shield extend out of the mounting seams to fasten with the shield on the opposite side.
[0016] Furthermore, the mounting seam has inward-facing fixing blocks on both sides for clamping the upright plate.
[0017] 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 forward protrusion on the surface of the shielding plate on the opposite side in the adjacent row of high-speed cable assemblies, so as to realize the common ground conduction of the U-shaped shielding plate and the shielding plate on the opposite side in the adjacent row of high-speed cable assemblies.
[0018] 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.
[0019] Furthermore, the opposite shielding plate is provided with positioning holes for positioning with the insulator.
[0020] Furthermore, the extension has a raised portion on one side in the width direction that is higher than other positions on the extension plate. The raised portion has a high riveting hole, and the other side has a low riveting hole in the thickness direction that is lower than the high riveting hole. When multiple U-shaped shielding sheets are arranged side by side, the raised portion of one of the adjacent U-shaped shielding sheets overlaps on the adjacent extension, and the high riveting hole on the raised portion is exactly aligned with the low riveting hole on the adjacent extension.
[0021] Furthermore, the extension is provided with a groove-shaped grounding claw facing the insulator, which contacts and clamps the grounding layer of the differential cable.
[0022] Furthermore, the extension is provided with positioning holes for positioning with the insulator.
[0023] Furthermore, the insulator has an injection-molded filler at the rear end of the shielding sheet on the opposite side.
[0024] Beneficial Effects: This invention provides an improved high-speed cable assembly, including a shielding structure comprising a U-shaped shielding sheet and a counter-shielding sheet disposed on its opposite side. Compared to existing high-speed cable assemblies that use welding and riveting to assemble the shielding structure, the high-speed cable assembly of this invention features a set of double-plate clamps on the counter-shielding plates. These double-plate clamps include jaws with opposite clamping directions, used to clamp the corresponding inner sides of adjacent vertical plates of adjacent U-shaped shielding sheets, i.e., the opposite sides of adjacent vertical plates. This eliminates the welding process during assembly, ensuring sufficient shielding while simplifying the assembly process.
[0025] The connector of this invention adopts the following technical solution:
[0026] A connector includes a housing and a cable bundle. A high-speed cable assembly is arranged side-by-side inside the housing. The high-speed cable assembly includes an insulator. Multiple contacts are arranged along the width direction inside the insulator. 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 U-shaped shielding plate corresponding to the contacts and a counter-shielding plate on its opposite side. The U-shaped shielding plate includes a base plate and upright plates connected to both sides of the base plate. An extension portion extends along the base plate away from the mating ends, forming a shielding structure at the rear end of the U-shaped shielding plate. The U-shaped shielding plate and the counter-shielding plate engage to form a shielding cavity, which provides shielding protection for the mating ends. Adjacent upright plates of adjacent U-shaped shielding plates are clamped and fixed by double-plate clamps provided on the counter-shielding plates. The double-plate clamps include claws with opposite clamping directions to clamp the opposite sides of the corresponding upright plates.
[0027] Furthermore, the adjacent grippers of the double-plate clamp are staggered along the length of the U-shaped shielding sheet.
[0028] Furthermore, the opposite shielding sheet is provided with a group of single-plate clamps at both ends in its width direction for clamping the outer vertical plate of the U-shaped shielding sheet at the edge. The single-plate clamp includes clamping claws on both sides corresponding to the outer vertical plate.
[0029] Furthermore, the adjacent grippers of the single-plate clamp are staggered along the length of the U-shaped shielding sheet.
[0030] Furthermore, the ends of the grippers of the double-plate clamp have bent sections that bend outwards to guide the corresponding upright plates into the double-plate clamp.
[0031] Furthermore, the ends of the grippers of the single-plate clamp have bent sections that bend outwards to guide the corresponding upright plates into the single-plate clamp.
[0032] Furthermore, the two upright plates of the U-shaped shielding sheet have side protrusions on their outer sides.
[0033] Furthermore, the two convex bulges are respectively set at the diagonal points of the U-shaped shielding sheet.
[0034] Furthermore, mounting seams are provided on both sides of each contact on the insulator, and the top of the two vertical plates of the U-shaped shield extend out of the mounting seams to fasten with the shield on the opposite side.
[0035] Furthermore, the mounting seam has inward-facing fixing blocks on both sides for clamping the upright plate.
[0036] 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 forward protrusion on the surface of the shielding plate on the opposite side in the adjacent row of high-speed cable assemblies, so as to realize the common ground conduction of the U-shaped shielding plate and the shielding plate on the opposite side in the adjacent row of high-speed cable assemblies.
[0037] 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.
[0038] Furthermore, the opposite shielding plate is provided with positioning holes for positioning with the insulator.
[0039] Furthermore, the extension has a raised portion on one side in the width direction that is higher than other positions on the extension plate. The raised portion has a high riveting hole, and the other side has a low riveting hole in the thickness direction that is lower than the high riveting hole. When multiple U-shaped shielding sheets are arranged side by side, the raised portion of one of the adjacent U-shaped shielding sheets overlaps on the adjacent extension, and the high riveting hole on the raised portion is exactly aligned with the low riveting hole on the adjacent extension.
[0040] Furthermore, the extension is provided with a groove-shaped grounding claw facing the insulator, which contacts and clamps the grounding layer of the differential cable.
[0041] Furthermore, the extension is provided with positioning holes for positioning with the insulator.
[0042] Furthermore, the insulator has an injection-molded filler at the rear end of the shielding sheet on the opposite side.
[0043] Beneficial effects: This invention improves connectors, especially high-speed cable assemblies within connectors. The high-speed cable assembly includes a shielding structure comprising a U-shaped shielding plate and a counter-shielding plate on its opposite side. By setting clamping claws with opposite clamping directions on the counter-shielding plates, these claws form a double-plate clamp. The set of double-plate clamps clamps and fixes the inner sides of adjacent vertical plates of adjacent U-shaped shielding plates, i.e., the opposite sides of the two vertical plates. This avoids the need for welding to connect the shielding structures on both sides, thus reducing assembly difficulty to some extent. Attached Figure Description

[0065] The features and performance of the present invention are further described in detail below with reference to the embodiments.
[0066] The inventive concept of this invention is as follows: Existing high-speed cable assemblies require riveting and welding to assemble their shielding structures, resulting in a cumbersome assembly process that affects overall production efficiency. This invention provides a high-speed cable assembly that uses a snap-fit clamping method to connect the shielding components on both sides, thereby simplifying the assembly process, improving production efficiency, and ensuring product quality reliability.
[0067] As a basic technical solution, the high-speed cable assembly of the present invention includes an insulator, and a shielding structure is provided on the outside of the insulator. The shielding structure includes a U-shaped shielding plate corresponding to the contact and a shielding plate on the opposite side. The U-shaped shielding plate and the shielding plate on the opposite side are fastened together. The adjacent vertical plates of the adjacent U-shaped shielding plates are clamped and fixed by a group of double plate clamps provided on the shielding plate on the opposite side. The connection and fixation of the shielding components on both sides can be completed without welding, which saves time and effort, improves the assembly efficiency of the high-speed cable assembly, and ensures the quality and reliability of the product.
[0068] Based on the above main concepts, the following embodiments are provided for illustration.
[0069] like Figure 1-2 As shown, the connector in this embodiment includes a housing 2 and a cable harness 3. Multiple high-speed cable assemblies 1 are arranged side-by-side within the housing 2. Each high-speed cable assembly 1 includes an insulator 11, and multiple contacts 10 are arranged along the width direction within the insulator 11. The portions of the contacts 10 extending out of the insulator 11 form mating ends, and the other ends are connected to differential cables 15. Figure 19As shown, a solder pad 101 is provided on one end of the contact 10 inside the insulator 11. The solder pad 101 is connected to the signal line 151 of the differential cable 15 by welding, gluing, 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 after the rear end of the shielding sheet 13 on the opposite side, for fixing the differential cable 15.
[0070] like Figure 3-10 As shown, a shielding structure is provided on 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.
[0071] The shielding structure includes a U-shaped shielding sheet 12 corresponding to the contact member 10 and a shielding sheet 13 disposed on the opposite side thereof, such as Figure 11-16 As shown, the U-shaped shielding sheet 12 includes a base plate 6 and upright plates 7 connected to both sides of the base plate 6. An extension portion 14 extends along the base plate 6 away from the insertion end, and the extension portion 14 constitutes the shielding structure at the rear end of the U-shaped shielding sheet 12. The U-shaped shielding sheet 12 and the opposite shielding sheet 13 are fastened together to form a shielding cavity, which provides shielding protection for the insertion end. In order to enhance the structural strength of the U-shaped shielding sheet 12, a riveting position 123 is provided at the connection between the base plate and the upright plate, and the two upright plates 7 are made conductive by riveting.
[0072] In existing shielding structures, the absence of spring clips at the mating end results in no contact between the U-shaped shielding sheets, leading to poor grounding shielding. Therefore, in this embodiment, the U-shaped shielding sheet 12 has inward-facing grounding spring clips 121 on both side uprights 7. These grounding spring clips 121 are formed by metal stamping extension from the surface of the uprights 7 or by connecting another metal sheet to the uprights 7. To prevent the grounding spring clips 121 from elastically deforming under force during mating with the male connector, the width direction, i.e., the arrangement direction of the U-shaped shielding sheet 12, is... Figure 3 In one embodiment, the grounding spring claws 121 of adjacent U-shaped shielding plates 12 in the thickness direction (the direction perpendicular to both the cable assembly insertion direction and the aforementioned width direction) touch. Figure 3There is a certain misalignment in the direction of the short arrows to allow for clearance between adjacent U-shaped shielding plates 12. Additionally, to ensure that the male connector can be accurately inserted into the shielding cavity and that the shielding tube of the male connector does not come into contact with the inner wall of the shielding cavity, in one embodiment, the U-shaped shielding plate 12 has an inwardly facing guide block 124 on each of the two 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 tube of the male connector from coming into contact with the shielding cavity.
[0073] like Figure 17-18 As shown, the opposite shielding plate 13 is provided with a set of double-plate clips. A "double-plate clip" is a clip structure that can simultaneously clamp two stacked plates. The double-plate clip includes jaws 131 with opposite clamping directions, so as to clamp the opposite sides of the corresponding upright plates 7 respectively. The two upright plates being clamped belong to two different shielding plates and are adjacent to each other. The set of double-plate clips is located on the opposite shielding plate 13 along the length direction, that is, the insertion direction of the cable assembly. Figure 7 The claws 131 are distributed in the direction of the center arrow. They can be arranged in pairs facing each other along the length of the U-shaped shielding sheet 12, with opposing claws 131 clamping the vertical plate 7 between them. However, considering that when adjacent claws 131 are facing each other, the double-clamped plates occupy a large installation space on the opposite shielding sheet 13, a more preferred embodiment has adjacent claws 131 of the double-clamped plates staggered along the length of the U-shaped shielding sheet 13. Correspondingly, the two vertical plates 7 on both sides of the U-shaped shielding sheet 13 have thinned sections at the top along the thickness direction of the vertical plate 7. These thinned sections form contact positions 122 for cooperating with the double-plate clamps to clamp the contact positions 122.
[0074] To further secure the clamping relationship between the U-shaped shielding plate 12 and the opposite shielding plate 13, the opposite shielding plate 13 is provided with a group of single-plate clamps at both ends in its width direction for clamping the outer upright plate 7 of the U-shaped shielding plate 12 at the edge. The single-plate clamp includes claws 131 that clamp the two sides of the corresponding outer upright plate 7. Similarly, to avoid the single clamp occupying a large installation space on the opposite shielding plate 13, preferably, the adjacent claws 131 of the single-plate clamp are staggered along the length direction of the U-shaped shielding plate 12.
[0075] When the U-shaped shielding plate 12 and the opposite shielding plate 13 are connected by interlocking, in order to ensure that the contact position 122 can accurately fall into the group of jaws 131 when the two are blindly inserted, in one embodiment, the end of the jaw 131 has a bent section that bends outward, and the outer side of the bent section forms a smooth guide surface, which guides the contact position 122 on the U-shaped shielding plate 12 when the U-shaped shielding plate 12 and the opposite shielding plate 13 are blindly inserted.
[0076] After the U-shaped shielding sheet 12 and the opposite shielding sheet 13 are interlocked, in order to ensure that the adjacent U-shaped shielding sheets 12 assembled side by side can achieve contact and conduction, and to avoid the adjacent U-shaped shielding sheets 12 being too close, causing the clamping claw 131 of the opposite shielding sheet 13 to have too loose contact with the contact position 122 of the U-shaped shielding sheet 12 and thus disengaging, in one embodiment, the two upright plates 7 of the U-shaped shielding sheet 12 are provided with side protrusions 125 on the outer side. The side protrusions 125 ensure that the adjacent upright plates 7 of the adjacent U-shaped shielding sheets 12 always maintain an appropriate distance, avoiding affecting the clamping connection between the clamping claw 131 and the contact position 122. In order to ensure that the U-shaped shielding sheets 12 on both sides always maintain a side-by-side position during the clamping action of the adjacent side protrusions 125, in a more preferred embodiment, the two side protrusions 125 of the U-shaped shielding sheet 12 are arranged crosswise at the diagonal of the U-shaped shielding sheet 12, forming a stable clamping relationship, and can effectively avoid the generation of crosstalk between adjacent differential pairs.
[0077] The U-shaped shielding sheet 12 has rivet holes 4 at the rear end of the base plate 6 for connecting with rivet posts on the insulator 11. The insulator 11 has mounting seams 115 on both sides of each contact member 10. The tops of the two upright plates 7 of the U-shaped shielding sheet 12 extend out of the mounting seams 115 and engage with the opposite shielding sheet 13. To further strengthen the connection between the U-shaped shielding sheet 12 and the insulator 11, in one embodiment, fixing blocks 116 facing inward are provided on both sides of the mounting seams 115 for clamping the upright plates 7.
[0078] 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 an outward-facing bottom spring piece 126. When multiple high-speed cable assemblies 1 are stacked, the bottom spring piece 126 contacts the forward protrusion 133 provided on the surface of the opposite shielding plate 13 in the adjacent row of high-speed cable assemblies 1, realizing that the U-shaped shielding plate 12 of the adjacent row of high-speed cable assemblies 1 and the opposite shielding plate 13 are grounded. There is also a grounding connection between the opposite shielding plate 13 and the differential cable 15. Figure 20As shown, 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. The insulating layer 152 is then covered by a grounding layer 153 and an outer sheath 154, wherein the grounding layer can be an aluminum foil layer. In one embodiment, the opposing shielding plate 13 has a groove-shaped grounding claw 132 facing the insulator 11. The surfaces of the grounding claw 132 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 132, allowing it to contact and clamp the grounding layer 153 of the differential cable 15. The opposing shielding plate 13 has rivet holes 4, which are used to connect with rivet posts 111 on the insulator 11. To facilitate the installation of the opposing shielding plate 13, in a more preferred embodiment, the opposing shielding plate 13 has positioning holes 5 for positioning with the insulator 11, facilitating alignment during installation.
[0079] The U-shaped shielding sheet 12 and the opposite shielding sheet 13 are fastened together to form a shielding cavity, which provides shielding protection for the mating end. The U-shaped shielding sheet 12 extends along the base plate 6 away from the mating end, with an extension portion 14. This extension portion 14 not only works in conjunction with the opposite shielding sheet 13 to better achieve full-coverage shielding of the high-speed cable assembly 1, but also ensures grounding conductivity between the extension portions 14 when the U-shaped shielding sheets 12 are arranged side-by-side. In a more preferred embodiment, the extension portion 14 has a raised portion on one side in the width direction, higher than the surface of the extension portion 14. The raised portion has a high riveting hole 141, and on the other side, a low riveting hole 142 in the thickness direction, lower than the high riveting hole 141. When the U-shaped shielding sheets 12 are arranged side-by-side, the high riveting hole 141 of one U-shaped shielding sheet 12 presses against the low riveting hole 142 of the adjacent U-shaped shielding sheet 12, achieving grounding conductivity between the extension portions 14 of the adjacent U-shaped shielding sheets. Similarly, the extension 14 is provided with a groove-shaped grounding claw 132 facing the insulator 11. The surfaces of the grounding claw 132 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 132. The grounding claw 132 contacts and clamps the grounding layer 153 of the differential cable 15. The extension 14 is connected to the rivet post 111 provided on the insulator 11 through the rivet hole 4, which further strengthens the connection reliability between the U-shaped shield 12 and the insulator 11. In a more preferred embodiment, to facilitate the installation of the U-shaped shield 12, a positioning hole 5 is provided on the extension 14 for positioning with the insulator 11, which facilitates alignment during the installation of the U-shaped shield 12.
[0080] 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.

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.
