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. The shielded cable assembly comprises a high-speed cable, a shielding shell and a contact. The shielding shell is riveted to the high-speed cable, and the connection stability is stronger and the shielding conduction performance is stable. The shielding shell surrounds the contact and the part where the contact contacts the high-speed cable on three sides, and a fully enclosed shielding structure is formed after the shielding buckle plate is buckled. 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 is cantilevered in the shielding cavity, and the shielding effect is good.

[0004] Although this high-speed cable assembly can achieve full shielding of each shielded cable assembly, during the assembly process of the shielding structure, the shielding buckle plate and the shielding shell are fixed by welding, the assembly process is relatively complicated, and no spring structure is set at the plug-in end of the high-speed cable assembly, resulting in poor grounding shielding effect at the plug-in end. 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, in which a contact piece is provided along the width direction.

A shielding structure is provided on the outside of the insulator, and the shielding structure includes a U-shaped shielding piece corresponding to the contact piece and an opposite shielding piece arranged on the opposite side thereof. The U-shaped shielding piece includes a bottom plate and vertical plates connected to both sides of the bottom plate, and an extension portion extends along the bottom plate away from the plug-in end. The extension portion constitutes a shielding structure at the rear end of the U-shaped shielding piece. The U-shaped shielding piece and the opposite shielding piece are buckled together to form a shielding cavity. The shielding cavity shields the plug-in end. Adjacent vertical plates of adjacent U-shaped shielding pieces are clamped and fixed by double-plate clamps arranged on the opposite shielding pieces. The double-plate clamp includes clamping claws with opposite clamping directions so as to clamp on opposite sides of the corresponding vertical plates respectively.

[0023] Beneficial effects: The present invention provides an improved high-speed cable assembly, including a shielding structure, wherein the shielding structure includes a U-shaped shielding sheet and an opposite shielding sheet arranged on the opposite side thereof. 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 opposite shielding plates in the high-speed cable assembly of the present invention are provided with a group of double-plate clamps, and the double-plate clamps include clamping claws with opposite clamping directions, which are used to clamp the corresponding inner sides of adjacent vertical plates of adjacent U-shaped shielding sheets, that is, the opposite sides of adjacent vertical plates. 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.

[0025] Furthermore, adjacent clamping jaws of the double plate clamp are arranged in a staggered manner along the length direction of the U-shaped shielding sheet.

[0032] Furthermore, the insulator is provided with mounting seams on both sides of each contact piece, and the tops of the two upright plates of the U-shaped shielding sheet extend out of the mounting seams to be buckled with the shielding sheet on the opposite side.

[0033] Furthermore, fixing blocks facing inwards are provided on both sides of the installation seam for clamping the vertical plates.

[0034] Furthermore, the bottom plate is provided with a bottom spring sheet facing outward. When multiple high-speed cable assemblies are stacked, the bottom spring sheet can contact the front convex bump provided on the surface of the opposite side shielding sheet in the adjacent row of high-speed cable assemblies, thereby realizing common ground conduction between the U-shaped shielding sheet and the opposite side shielding sheet of the adjacent row of high-speed cable assemblies.

[0044] The features and performance of the present invention are further described in detail below in conjunction with the embodiments.

[0045] 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 to assemble 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 that uses a snap-fit ​​clamping method to connect the shielding parts on both sides, thereby simplifying the assembly process, improving production efficiency, and ensuring the reliability of product quality.

[0046] As a basic technical solution, the high-speed cable assembly of the present invention includes an insulator, a shielding structure is arranged on the outside of the insulator, the shielding structure includes a U-shaped shielding sheet corresponding to the contact piece and an opposite shielding sheet arranged on the opposite side thereof, the U-shaped shielding sheet is buckled with the opposite shielding sheet, and adjacent vertical plates of adjacent U-shaped shielding sheets are clamped and fixed by a group of double plate clamps arranged on the opposite shielding sheet, and the connection and fixation of the shielding pieces 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.

[0047] Based on the above main concepts, embodiments are provided below for illustration.

[0048] like Figure 1-2 As shown, the connector in the embodiment includes a housing 2 and a cable harness 3, wherein a plurality of high-speed cable assemblies 1 are arranged side by side in the housing 2. The high-speed cable assembly 1 includes an insulator 11, wherein a plurality of contacts 10 are arranged in the insulator 11 along the width direction, and the portion of the contact 10 extending out of the insulator 11 constitutes a plug-in end, and the other end is connected to a differential cable 15. Fig.19As shown, a pad 101 is provided on one end of the contact 10 in the insulator 11, and the 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 solder joint to prevent salt spray corrosion. A wiring position 113 is provided on the insulator 11 of the high-speed cable assembly 1 for placing the differential cable 15. An injection molding position 114 is also provided 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 opposite shielding sheet 13, which is used to fix the differential cable 15.

[0049] like Figure 3-10 As shown, a shielding structure is provided 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.

[0050] The shielding structure includes a U-shaped shielding sheet 12 corresponding to the contact 10 and an opposite side shielding sheet 13 arranged on the opposite side thereof. Figure 11-16 As shown, the U-shaped shielding sheet 12 includes a bottom plate 6 and vertical plates 7 connected to both sides of the bottom plate 6, and an extension portion 14 extends along the bottom plate 6 away from the plug-in end, and the extension portion 14 constitutes a shielding structure at the rear end of the U-shaped shielding sheet 12. The U-shaped shielding sheet 12 and the opposite side shielding sheet 13 are buckled to form a shielding cavity, and the shielding cavity shields and protects the plug-in end. In order to enhance the structural strength of the U-shaped shielding sheet 12 body, the U-shaped shielding sheet 12 is provided with a rivet position 123 at the connection between the bottom plate and the vertical plate, and the vertical plates 7 on both sides are connected by riveting.

[0051] The shielding structure in the prior art does not have a spring sheet structure at the plug-in end, resulting in no contact between the U-shaped shielding sheets at the plug-in end, so the grounding shielding effect is poor. Therefore, the U-shaped shielding sheet 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 sheet 12 ( Figure 3 In one embodiment, the grounding claws 121 of the U-shaped shielding sheet 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 U-shaped shielding sheet 12 touch each other in the thickness direction (i.e., the direction perpendicular to the cable assembly plugging direction, i.e., the width direction mentioned above). Figure 3There is a certain misalignment in the direction of the middle and short arrows, which is used to avoid the adjacent U-shaped shielding sheets 12. In addition, in order to ensure that the male connector can be accurately inserted into the shielding cavity, and the shielding tube of the male connector does not touch the inner wall of the shielding cavity, in one embodiment, the U-shaped shielding sheet 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, and 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 tube from touching the shielding cavity.

[0052] like Figure 17-18 As shown, a set of double-plate clamps are provided on the opposite shielding sheet 13. The so-called "double-plate clamp" is a clamp structure that can clamp two stacked plates at the same time. The double-plate clamp includes clamping claws 131 with opposite clamping directions to clamp on the opposite sides of the corresponding vertical plates 7 respectively. The two clamped vertical plates belong to two different shielding sheets and are adjacent. The set of double-plate clamps are arranged on the opposite shielding sheet 13 along the length direction, that is, the plug-in direction of the cable assembly. Figure 7 The arrangement of the clamps 131 can be arranged in pairs along the length direction of the U-shaped shielding sheet 12, and the two opposing clamps 131 clamp the vertical plate 7 between them. However, considering that when the two adjacent clamps 131 are in a relative relationship, the installation position occupied by the double clamps on the opposite shielding sheet 13 is larger, therefore, in a more preferred embodiment, the adjacent clamps 131 of the double clamps are arranged in a staggered manner along the length direction of the U-shaped shielding sheet 13. Correspondingly, the vertical plates 7 on both sides of the U-shaped shielding sheet 13 are provided with thinned sections along the thickness direction of the vertical plates 7 at the top, and the thinned sections constitute the contact position 122 for cooperating with the double plate clamp to clamp the contact position 122.

[0053] In order to further tighten the clamping relationship between the U-shaped shielding sheet 12 and the opposite side shielding sheet 13, the opposite side shielding sheet 13 is also provided with a group of single plate clamps at both ends in the width direction thereof, which are used to clamp the outer vertical plate 7 of the U-shaped shielding sheet 12 at the edge. The single plate clamp includes clamping claws 131 on both sides of the corresponding outer vertical plate 7. Similarly, in order to avoid a large installation position occupied by the single clamp on the opposite side shielding sheet 13, preferably, the adjacent clamping claws 131 of the single plate clamp are staggered along the length direction of the U-shaped shielding sheet 12.

[0054] When the U-shaped shielding sheet 12 is buckled and connected with the opposite side shielding sheet 13, in order to ensure that the contact position 122 can accurately fall into the group of clamps 131 when the two are blindly plugged, in one embodiment, the end of the clamp 131 has a bending section bent toward the outside, and the outer side surface of the bending section constitutes a smooth guiding surface, which guides the contact position 122 on the U-shaped shielding sheet 12 when the U-shaped shielding sheet 12 is blindly plugged with the opposite side shielding sheet 13.

[0055] After the U-shaped shielding sheet 12 is buckled with the opposite side shielding sheet 13, 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 to each other, resulting in the clamping claw 131 of the opposite side shielding sheet 13 and the contact position 122 of the U-shaped shielding sheet 12 being too loose and causing the contact to be lost, in one embodiment, the two vertical plates 7 of the U-shaped shielding sheet 12 are provided with side convex humps 125 on the outside, and the side convex humps 125 ensure that the adjacent vertical plates 7 of the adjacent U-shaped shielding sheets 12 always maintain an appropriate distance, avoiding the influence on the clamping connection between the clamping claw 131 and the contact position 122. In order to make the U-shaped shielding sheets 12 on both sides always maintain a side-by-side position relationship during the tightening action of the adjacent side convex humps 125, in a more preferred embodiment, the convex humps 125 on both sides of the U-shaped shielding sheet 12 are cross-arranged at the diagonal positions of the U-shaped shielding sheet 12 to form a stable tightening relationship, and can effectively avoid the occurrence of crosstalk between adjacent differential pairs.

[0056] The U-shaped shielding sheet 12 is provided with a rivet hole 4 at the rear end of the bottom plate 6 for cooperating with the rivet column on the insulator 11. The insulator 11 is provided with a mounting seam 115 on both sides of each contact member 10. The mounting seams 115 extend from the top of the two vertical plates 7 of the U-shaped shielding sheet 12 to buckle with the opposite shielding sheet 13. In order to further strengthen the connection between the U-shaped shielding sheet 12 and the insulator 11, in one embodiment, the two sides of the mounting seam 115 are provided with fixing blocks 116 facing inwards for clamping the vertical plates 7.

[0057] Since the high-speed cable assembly 1 in the connector of the present invention is stacked in the housing 2 for use, in order to ensure the overall shielding effect of the connector, in one embodiment, a bottom spring sheet 126 facing outward is provided on the bottom plate 6. When multiple high-speed cable assemblies 1 are stacked, the bottom spring sheet 126 contacts the front convex bump 133 provided on the surface of the opposite shielding sheet 13 in the adjacent row of high-speed cable assemblies 1, thereby achieving common ground connection between the U-shaped shielding sheet 12 and the opposite shielding sheet 13 of the adjacent row of high-speed cable assemblies 1. There is also a ground connection between the opposite shielding sheet 13 and the differential cable 15. Fig. 20As shown, the differential cable 15 includes a pair of signal lines 151 arranged side by side, the signal lines 151 are wrapped with an insulating layer 152, and the insulating layer 152 is covered with a grounding layer 153 and an outer sheath 154 in sequence, wherein the grounding layer can be an aluminum foil layer. In one embodiment, the opposite side shielding sheet 13 is provided with a groove-shaped grounding claw 132 facing the insulator 11, and the surface of the grounding claw 132 corresponding to the bottom and side of the U-shape is gold-plated, and there is a certain amount of extrusion between the claws of the grounding claw 132, and the grounding claw 132 contacts and clamps the grounding layer 153 of the differential cable 15. The opposite 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. In order to facilitate the installation of the opposite side shielding sheet 13, in a more preferred embodiment, the opposite side shielding sheet 13 is provided with a positioning hole 5 for positioning with the insulator 11, so as to facilitate alignment when the opposite side shielding sheet 13 is installed.

[0058] The U-shaped shielding sheet 12 and the opposite shielding sheet 13 are buckled together to form a shielding cavity, and the shielding cavity shields and protects the plug-in end. The U-shaped shielding sheet 12 has an extension portion 14 extending along the bottom plate 6 away from the plug-in end. The extension portion 14 can not only be used in conjunction with the opposite shielding sheet 13 to better achieve full shielding of the high-speed cable assembly 1, but also can achieve grounding conduction 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 is provided with a raised portion higher than the plate surface of the extension portion 14 on one side in the width direction, and a high rivet hole 141 is provided on the raised portion, and a low rivet hole 142 lower than the high rivet hole 141 in the thickness direction is provided on the other side. When the U-shaped shielding sheets 12 are arranged side by side, the high rivet hole 141 of one U-shaped shielding sheet 12 is pressed on the low rivet hole 142 of the adjacent U-shaped shielding sheet 12, so as to achieve grounding conduction 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 surface of the grounding claw 132 corresponding to the bottom and side of the U-shape is gold-plated. There is a certain amount of extrusion 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 with the rivet column 111 provided on the insulator 11 through the rivet hole 4, further strengthening the connection reliability between the U-shaped shielding sheet 12 and the insulator 11. In order to facilitate the installation of the U-shaped shielding sheet 12, in a more preferred embodiment, a positioning hole 5 for positioning with the insulator 11 is provided on the extension 14, which is convenient for alignment when the U-shaped shielding sheet 12 is installed.

[0059] 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.

[0060] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. The patent protection scope of the present invention shall be based on the claims. All equivalent structural changes made using the contents of the description and drawings of the present invention should also be included in the protection scope of the present invention.
