Description

Technical Field

[0001] The present invention belongs to the field of connection devices, and particularly relates to a cable connector, a cable assembly and a manufacturing method thereof. Background Art

[0002] When transmitting differential signals, a cable connector is required. To ensure the accuracy of signal transmission and meet the crosstalk requirements when transmitting signals at high speeds, the cable connector includes a cable shielding and grounding structure for shielding the cable.

[0003] For example, a Chinese patent application with the publication number CN117080809A and the publication date of November 17, 2023 discloses a cable shielding and grounding structure and a high-speed cable connector. The high-speed cable connector includes a cable shielding and grounding structure and a cable. The cable shielding and grounding structure includes an upper shielding sheet and a lower shielding sheet. One end of the cable is located between the upper and lower shielding sheets. The upper shielding sheet is provided with an upper contact structure for pressing the cable shielding layer downward, and the lower shielding sheet is provided with a lower contact structure for pressing the cable shielding layer upward. The lower contact structure corresponds to the upper contact structure up and down to clamp the cable shielding layer between the upper and lower contact structures, thereby realizing the conduction between the upper and lower shielding sheets and the cable shielding layer. Preferably, the upper contact structure is an upper grounding spring claw, so that the upper and lower contact structures can clamp more specifications of cables.

[0004] However, when using the above cable shielding and grounding structure, since the upper grounding spring claw and the lower contact structure are deformed under the pressure when cooperating with the cable shielding layer, when the size of the cable is too small, the upper grounding spring claw and the lower contact structure cannot contact the cable at the same time, and thus cannot clamp the cable. Therefore, the above cable shielding and grounding structure cannot be applied to cables with smaller specifications, and the applicable range is limited. Summary of the Invention

[0005] The purpose of the present invention is to provide a cable assembly to solve the technical problem that the applicable cable specifications of the cable assembly in the prior art are limited.

[0006] The purpose of the present invention is also to provide a cable connector to solve the same technical problem as above.

[0007] The purpose of the present invention is also to provide a manufacturing method of a cable assembly to solve the same technical problem as above.

[0008] To achieve the above purpose, the technical solution of the cable assembly provided by the present invention is: A cable assembly includes an upper shielding sheet, a lower shielding sheet, and a cable. One of the upper and lower shielding sheets is provided with a contact structure that contacts the cable shielding layer of the cable. The other of the upper and lower shielding sheets includes a grounding through-hole and a pressing portion. The cable assembly further includes a conductive adjusting sheet. The conductive adjusting sheet includes an adjusting sheet body and a grounding spring claw that is connected to the adjusting sheet body and passes through the grounding through-hole to press the cable shielding layer. The grounding spring claw and the contact structure are vertically corresponding. The pressing portion is used to press the grounding spring claw to deform it toward the cable shielding layer. The conductive adjusting sheet is used to move during the assembly of the cable assembly to adjust the deformation degree of the grounding spring claw, and is used to be fixedly connected to the corresponding shielding sheet after the grounding spring claw is deformed until the cable shielding layer is clamped between the grounding spring claw and the contact structure.

[0009] Further, one of the adjusting sheet body and the shielding sheet provided with the grounding through-hole is connected with a slider, and the other is connected with a sliding portion for guiding and slidingly cooperating with the slider in the front-rear direction to adjust the deformation degree of the grounding spring claw.

[0010] Further, the shielding sheet provided with the grounding through-hole has a sliding cooperation section. Sliders are provided on both the left and right sides of the adjusting sheet body. The distance between the sliders on the left and right sides matches the left-right width of the sliding cooperation section. The left and right side surfaces of the sliding cooperation section constitute the sliding portion.

[0011] Further, the shielding sheet provided with the grounding through-hole also has wider sections on the front and rear sides of the sliding cooperation section. The left and right sides of the wider sections protrude from the sliding cooperation section to form notches, and the sliders are located in the notches.

[0012] Further, sliders are provided on both the left and right sides of the shielding sheet provided with the grounding through-hole. The distance between the sliders on the left and right sides matches the left-right width of the adjusting sheet body. The left and right side surfaces of the adjusting sheet body constitute the sliding portion.

[0013] Further, a pressing arm that extends toward the inside of the grounding through-hole is integrally connected to the hole wall of the grounding through-hole, and the end of the pressing arm forms the pressing portion.

[0014] Further, an avoidance opening for avoiding a positioning pin during the assembly of the cable assembly is provided on the adjusting sheet body.

[0015] Further, the grounding through-holes are arranged in rows in the left-right direction, and at least one row of grounding through-holes is arranged in the front-rear direction. The number of conductive adjusting sheets is the same as the number of rows of grounding through-holes, and the number of upper grounding spring claws of each conductive adjusting sheet is the same as the number of grounding through-holes in each row. The upper grounding spring claws of each conductive adjusting sheet pass through each row of grounding through-holes simultaneously.

[0016] The beneficial effects of the cable assembly provided by the present invention are as follows: The present invention is an improved invention. The main difference between the present invention and the prior art is that in the prior art, the upper shielding sheet has an upper grounding spring claw, while in the present invention, the conductive adjusting sheet has a grounding spring claw, and one of the shielding sheets has a grounding perforation and a pressing portion for pressing the grounding spring claw. Among them, the pressing portion is used to press the grounding spring claw, so as to adjust the distance between the grounding spring claw and the contact structure, so that the grounding spring claw and the contact structure can clamp more specifications of cables. After the grounding spring claw and the contact structure clamp the cable shielding layer, the adjusting sheet body is fixedly connected to the shielding sheet provided with the grounding perforation, so as to fix the position of the grounding spring claw and expand the range of cables applicable to the cable assembly.

[0017] To achieve the above object, the technical solution of the cable connector provided by the present invention is as follows: A cable connector includes a housing and at least two cable assemblies mounted on the housing. The cable assembly includes an upper shielding sheet, a lower shielding sheet and a cable. One of the upper and lower shielding sheets is provided with a contact structure in contact with the cable shielding layer of the cable. The other of the upper and lower shielding sheets includes a grounding perforation and a pressing portion. The cable assembly further includes a conductive adjusting sheet, which includes an adjusting sheet body and a grounding spring claw connected to the adjusting sheet body and passing through the grounding perforation to press the cable shielding layer. The grounding spring claw corresponds to the contact structure up and down. The pressing portion is used to press the grounding spring claw to deform it towards the cable shielding layer. The conductive adjusting sheet is used to move during the assembly of the cable assembly to adjust the deformation degree of the grounding spring claw, and is used to be fixedly connected to the corresponding shielding sheet after the grounding spring claw deforms until the cable shielding layer is clamped between the grounding spring claw and the contact structure.

[0018] Furthermore, one of the adjusting sheet body and the shielding sheet provided with the grounding perforation is connected with a slider, and the other is connected with a sliding portion for guiding and slidingly matching with the slider in the front-rear direction to adjust the deformation degree of the grounding spring claw.

[0019] Furthermore, the shielding sheet provided with the grounding perforation has a sliding fit section. Sliders are provided on both the left and right sides of the adjusting sheet body. The distance between the sliders on the left and right sides matches the left and right widths of the sliding fit section. The left and right side surfaces of the sliding fit section constitute the sliding portion.

[0020] Furthermore, the shielding sheet provided with the grounding perforation also has wider sections on the front and rear sides of the sliding fit section. The left and right sides of the wider sections protrude from the sliding fit section to form notches, and the sliders are located in the notches.

[0021] Furthermore, sliders are provided on both the left and right sides of the shielding sheet provided with the grounding perforation. The distance between the sliders on the left and right sides matches the left and right widths of the adjusting sheet body. The left and right side surfaces of the adjusting sheet body constitute the sliding portion.

[0022] Furthermore, a pressing arm extending into the grounding via hole is integrally connected to the hole wall of the grounding via hole, and the pressing portion is formed at the end of the pressing arm.

[0023] Furthermore, an avoidance opening for avoiding the positioning pin during the assembly of the cable assembly is provided on the adjusting piece body.

[0024] Furthermore, the grounding via holes are arranged in rows in the left - right direction, and at least one row of grounding via holes is arranged in the front - back direction. The number of conductive adjusting pieces is the same as the number of rows of grounding via holes, and the number of upper grounding claws of each conductive adjusting piece is the same as the number of grounding via holes in each row. The upper grounding claws of each conductive adjusting piece pass through each row of grounding via holes simultaneously.

[0025] The beneficial effects of the cable connector provided by the present invention are as follows: The present invention is an improved invention. The main difference between the present invention and the prior art is that: in the prior art, the upper shielding piece has upper grounding claws, while in the present invention, the conductive adjusting piece has grounding claws, and one of the shielding pieces has a grounding via hole and a pressing portion for pressing the grounding claws. Among them, the pressing portion is used to press the upper grounding claws, so as to adjust the distance between the grounding claws and the contact structure, enabling the grounding claws and the contact structure to clamp cables of more specifications. After the grounding claws and the contact structure clamp the cable shielding layer, the adjusting piece body is fixedly connected to the shielding piece provided with the grounding via hole, thereby fixing the position of the grounding claws and expanding the range of cables applicable to the cable assembly.

[0026] To achieve the above - mentioned purpose, the technical solution of the manufacturing method of the cable assembly provided by the present invention is as follows: A manufacturing method of a cable assembly includes the process of respectively installing the upper and lower shielding pieces onto the insulator. One of the upper and lower shielding pieces is provided with a contact structure, and the other of the upper and lower shielding pieces includes a grounding via hole and a pressing portion. After the upper and lower shielding pieces are installed on both sides of the insulator, the conductive adjusting piece installation step is performed. In the conductive adjusting piece installation step, first, the grounding claws of the conductive adjusting piece pass through the grounding via hole and are pressed towards the cable shielding layer of the cable by the pressing portion. Then, the conductive adjusting piece is moved to adjust the deformation degree of the grounding claws until the grounding claws and the contact structure clamp the cable shielding layer. Finally, the conductive adjusting piece is fixed on the shielding piece provided with the grounding via hole.

[0027] The beneficial effects of the manufacturing method of the cable assembly provided by the present invention are as follows: The present invention is an improved invention. The main difference between the present invention and the prior art lies in that in the present invention, after the upper and lower shielding sheets are installed on both sides of the insulator, there is also a step of installing the conductive adjustment sheet. When performing the step of installing the conductive adjustment sheet, the grounding spring claw contacts the cable shielding layer. At the same time, by moving the conductive adjustment sheet, the distance between the grounding spring claw and the contact structure can be adjusted, so that the grounding spring claw and the contact structure can clamp more specifications of cables, expanding the range of cables applicable to the cable assembly.

[0030] To solve the problems in the background art, the core inventive concept of the present invention is: arranging the upper grounding spring claw on a separate conductive adjusting piece, and arranging a pressing part on the upper shielding piece. By moving the upper grounding spring claw, the deformation degree of the upper grounding spring claw is adjusted, so as to adjust the distance between the upper grounding spring claw and the lower contact structure, enabling the cable assembly to be applicable to more cable specifications.

[0031] To facilitate the understanding of the present invention by those skilled in the art, in the present invention, the "up and down direction" is defined, and the "up and down direction" is the same as the arrangement direction of the two shielding pieces. In actual use, according to the different postures of the cable assembly and the orientation of the observer, the arrangement direction of the two shielding pieces can also be the "actual direction" such as the left and right direction, the front and back direction, etc. At this time, this "actual direction" is used as the "up and down direction" in the present invention. At the same time, there is no clear distinction between up and down in the present invention, and up and down can be interchanged.

[0032] The following further describes the present invention in detail with reference to embodiments.

[0033] Specific embodiments of the cable assembly provided by the present invention: As Figures 1 - 10 shown, the cable assembly includes a cable 31, a pin component, an upper shielding piece 1, a lower shielding piece 4, a conductive adjusting piece 2, and a support plate 5. When there are multiple cables 31, all the cables 31 can be formed into a cable module 3 (the cable module 3 includes an insulator, and the cables 31 are connected to the insulator) by injection molding or assembly to facilitate the assembly of the cable assembly.

[0034] In the present invention, one of the upper and lower shielding pieces is provided with a contact structure that contacts the cable shielding layer 311 of the cable 31, and the other includes a grounding through hole 14 and a pressing part 11. The cable assembly further includes a conductive adjusting piece 2, and the conductive adjusting piece 2 includes an adjusting piece body 22 and a grounding spring claw that is connected to the adjusting piece body 22 and passes through the grounding through hole 14 to press the cable shielding layer 311. The grounding spring claw and the contact structure are vertically corresponding; the pressing part 11 is used to press the grounding spring claw to deform it towards the cable shielding layer 311, and the conductive adjusting piece 2 is used to move during the assembly of the cable assembly to adjust the deformation degree of the grounding spring claw, and is used to be fixedly connected to the corresponding shielding piece after the grounding spring claw deforms until the cable shielding layer 311 is clamped between the grounding spring claw and the contact structure.

[0035] To facilitate the understanding of the present invention by those skilled in the art, the following takes the upper shielding piece 1 including the grounding through hole 14 as an example to introduce the present invention.

[0036] In a basic specific embodiment, a lower contact structure for upwardly pressing the cable shielding layer 311 is provided on the lower shielding sheet 4, and one end of the cable 31 is located between the upper and lower shielding sheets; the upper shielding sheet 1 includes a grounding perforation 14 and a pressing portion 11; the conductive adjusting sheet 2 includes an upper grounding spring claw 21, the upper grounding spring claw 21 corresponds to the lower contact structure up and down, and the upper grounding spring claw 21 is integrally formed with the adjusting sheet body 22; the pressing portion 11 is used for downwardly pressing the upper grounding spring claw 21, and after the upper grounding spring claw 21 is deformed to cooperate with the lower contact structure and clamp the cable shielding layer 311, the adjusting sheet body 22 is used for fixedly connecting with the upper shielding sheet 1 (specifically, the upper surface of the upper shielding sheet 1). At this time, the upper shielding sheet 1 is electrically connected to the cable shielding layer 311 through the conductive adjusting sheet 2, so as to realize the conduction between the upper shielding sheet 1 and the cable shielding layer 311.

[0037] In another basic specific embodiment, the upper grounding spring claw 21 is separately manufactured, and the upper grounding spring claw 21 is fixedly connected to the adjusting sheet body 22 by welding; alternatively, a slot extending in the front-rear direction is provided on the adjusting sheet body 22, one end of the upper grounding spring claw 21 is inserted into the slot, and the upper grounding spring claw 21 is in interference fit with the adjusting sheet body 22, so as to realize the fixed connection between the upper grounding spring claw 21 and the adjusting sheet body 22.

[0038] Wherein, welding holes 23 are provided on the adjusting sheet body 22, and when assembling the cable assembly, the adjusting sheet body 22 and the connecting part are welded and fixed by using the welding holes 23; the upper grounding spring claw 21 is arranged on the front side or the rear side of the adjusting sheet body 22. When assembling the cable assembly, if the upper grounding spring claw 21 is arranged on the front side of the adjusting sheet body 22, the conductive adjusting sheet 2 needs to be moved forward, and if the upper grounding spring claw 21 is arranged on the rear side of the adjusting sheet body 22, the conductive adjusting sheet 2 needs to be moved backward.

[0039] It should be noted that in the specific embodiment where the upper shielding sheet 1 includes the grounding perforation 14, there is no improvement in the cable 31, the pin component, the cable module 3, the lower shielding sheet 4 and the support plate 5. The structures of the cable 31, the pin component, the cable module 3 and the lower shielding sheet 4 can refer to the Chinese patent application for invention with the application publication number CN117080809A. In the specific embodiment where the upper shielding sheet 1 includes the grounding perforation 14, except that the upper shielding sheet 1 does not include the upper grounding spring claw 21 and has the side grounding spring claw 12, the grounding perforation 14 and the pressing portion 11, the remaining structures are the same as those of the existing upper shielding sheet 1, and can specifically refer to the Chinese patent application for invention with the application publication number CN117080809A.

[0040] The same as that in the Chinese patent application for invention with the application publication number CN117080809A, the lower contact structure of the lower shielding sheet 4 can also be structures such as a lower grounding spring claw or a lower grounding convex hull, etc., which will not be elaborated here.

[0041] In the present invention, the upper shielding sheet 1 is made of an existing conductive material (such as copper, aluminum, or stainless steel), and the conductive adjusting sheet 2 is also made of an existing conductive material (such as copper, aluminum, or stainless steel).

[0042] In summary, the main differences between the present invention and the prior art are as follows: In the prior art, the upper shielding sheet 1 has an upper grounding spring claw 21, while in the present invention, the conductive adjusting sheet 2 has an upper grounding spring claw 21, and the upper shielding sheet 1 has a grounding through hole 14 and a pressing portion 11 for pressing the upper grounding spring claw 21 downward. Among them, the pressing portion 11 is used to press the upper grounding spring claw 21 downward, so as to adjust the distance between the upper grounding spring claw 21 and the lower contact structure, enabling the upper grounding spring claw 21 and the lower contact structure to clamp more specifications of the cable 31. After the upper grounding spring claw 21 and the lower contact structure clamp the cable shielding layer 311, the adjusting sheet body 22 is fixedly connected to the upper surface of the upper shielding sheet 1, thereby fixing the position of the upper grounding spring claw 21 and expanding the range of cables applicable to the cable assembly.

[0043] When assembling the cable assembly, the upper shielding sheet 1 has an upper positioning hole 13, and the lower shielding sheet 4 has a lower positioning hole. When assembling the upper shielding sheet 1, the lower shielding sheet 4, the cable module 3, the support plate 5, and the pin component together, the positioning pin passes through the upper positioning hole 13 and the lower positioning hole simultaneously to fix the relative positions of the upper shielding sheet 1 and the lower shielding sheet 4. Of course, a positioning pin can also be provided on one of the lower shielding sheet 4 or the upper shielding sheet 1, and a positioning hole can be provided on the other.

[0044] In the present invention, to avoid interference between the adjusting sheet body 22 and the positioning pin, in Figures 6 - 7 the specific embodiment shown, the adjusting sheet body 22 is provided with an avoidance opening 24 for avoiding the positioning pin when assembling the cable assembly.

[0045] In other specific embodiments, the avoidance opening 24 may not be provided on the adjusting sheet body 22. At this time, the front and rear dimensions of the upper grounding spring claw 21 are relatively long, and the upper grounding spring claw 21 and the lower contact structure have already clamped the cable shielding layer 311 before the adjusting sheet body 22 interferes with the positioning pin.

[0046] In the present invention, according to actual needs, the number of the conductive adjusting sheets 2 can be one, two, or more, and correspondingly, the number of rows of the grounding through holes 14 can also be one row, two rows, or more rows (the number of the conductive adjusting sheets 2 is the same as the number of rows of the grounding through holes 14).

[0047] As Figures 1 - 10 shown, when the cable assembly includes two conductive adjusting sheets 2 and two rows of grounding through holes 14, preferably, in a specific embodiment, avoidance openings 24 are provided on both of the two conductive adjusting sheets 2. When assembling the cable assembly, it is not necessary to distinguish the specifications of the conductive adjusting sheets 2, which is convenient for on-site management.

[0048] In other specific embodiments, only one conductive adjusting piece 2 has an avoidance opening 24, and the other conductive adjusting piece 2 does not have an avoidance opening 24. When assembling the cable assembly, it is necessary to distinguish the specifications of the conductive adjusting pieces 2 to avoid interference between the conductive adjusting pieces 2 and the positioning pins.

[0049] Similarly, when the cable assembly includes at least three conductive adjusting pieces 2, at least one of the conductive adjusting pieces 2 is provided with an avoidance opening 24.

[0050] To facilitate the assembly of the cable assembly, the grounding through holes 14 are arranged in rows in the left-right direction, and there is at least one row of grounding through holes 14 arranged in the front-back direction. The number of conductive adjusting pieces 2 is the same as the number of rows of grounding through holes 14, and the number of upper grounding claws 21 of each conductive adjusting piece 2 is the same as the number of grounding through holes 14 in each row. The upper grounding claws 21 of each conductive adjusting piece 2 pass through the grounding through holes 14 in each row at the same time, thereby reducing the number of conductive adjusting pieces 2 that need to be assembled and facilitating the assembly of the cable assembly.

[0051] In Figures 1 - 10 In the shown specific embodiment, each conductive adjusting piece 2 has four upper grounding claws 21 arranged in the left-right direction. The upper shielding piece 1 has two rows and four columns of grounding through holes 14 (that is, the number of grounding through holes 14 in each row is four), and four cables 31 are formed into a cable module 3 by injection molding.

[0052] In other specific embodiments, the number of rows of grounding through holes 14 can also be one row, three rows or more rows; only one, two, three or other numbers of upper grounding claws 21 can also be provided on the conductive adjusting piece 2. Among them, the number of upper grounding claws 21 of the conductive adjusting piece 2, the number of grounding through holes 14 in each row is the same as the number of cables 31.

[0053] To facilitate the forward and backward movement of the conductive adjusting piece 2, preferably, in a specific embodiment, one of the adjusting piece body 22 and the upper shielding piece 1 is connected with a slider 25, and the other is connected with a sliding part for guiding and sliding cooperation with the slider 25 in the front-back direction to adjust the deformation degree of the upper grounding claw 21.

[0054] Before moving the conductive adjusting piece 2 forward and backward, first make the slider 25 and the sliding part guide and slide cooperate in the front-back direction, so as to avoid the relative movement between the conductive adjusting piece 2 and the upper shielding piece 1 having a lateral displacement in the left-right direction and avoid the left-right misalignment between the conductive adjusting piece 2 and the upper shielding piece 1.

[0055] Such as Figures 1 - 10As shown, in a specific embodiment, the upper shielding sheet 1 has a sliding fit section 15 (i.e., a narrower section). Sliders 25 are provided on both the left and right sides of the adjusting sheet body 22. The distance between the sliders 25 on the left and right sides matches the left and right widths of the sliding fit section 15. The left and right side surfaces of the sliding fit section 15 constitute the sliding part, and the structure is simple.

[0056] Preferably, both the front and rear sides of the sliding fit section 15 are wider sections 16. Both the left and right sides of the wider section 16 protrude from the sliding fit section 15 to form notches, and the sliders 25 are located in the notches. At this time, adding the conductive adjusting sheet 2 will not increase the left and right dimensions of the cable assembly.

[0057] In other specific embodiments, the left and right widths of the wider section 16 can also be smaller than the left and right widths of the conductive adjusting sheet 2. At this time, the left and right dimensions of the cable assembly are larger.

[0058] In other specific embodiments, the sliders 25 can also be provided on the upper shielding sheet 1. Specifically, sliders 25 are provided on both the left and right sides of the upper shielding sheet 1. The distance between the sliders 25 on the left and right sides matches the left and right widths of the adjusting sheet body 22. The left and right side surfaces of the adjusting sheet body 22 constitute the sliding part.

[0059] In other specific embodiments, one of the upper shielding sheet 1 and the adjusting sheet body 22 is provided with a slider 25, and the other is provided with a sliding groove matching the slider 25. The sliding groove extends in the front-rear direction. Among them, the sliding groove is provided on the upper surface of the upper shielding sheet 1 or the lower surface of the adjusting sheet body 22. Correspondingly, the slider 25 is provided on the lower surface of the conductive adjusting sheet 2 or the upper surface of the upper shielding sheet 1.

[0060] In the present invention, the shape of the slider 25 can be a cuboid shape, a cube shape, a cylindrical shape, a cylindrical tube shape, etc., which will not be elaborated here.

[0061] In other specific embodiments, before the conductive adjusting sheet 2 is fixedly connected to the upper shielding sheet 1, the conductive adjusting sheet 2 and the upper shielding sheet 1 are not in guiding cooperation. At this time, when moving the conductive adjusting sheet 2 in the front-rear direction, it is necessary to keep the conductive adjusting sheet 2 and the upper shielding sheet 1 aligned to avoid misalignment between the conductive adjusting sheet 2 and the upper shielding sheet 1.

[0062] In Figure 9In the specific embodiment shown, a pressing arm integrally connected to the hole wall of the grounding through hole 14 and extending into the grounding through hole 14 is provided, and the end of the pressing arm forms the pressing portion 11. The grounding through hole 14 is a "U" - shaped hole, and the opening of the "U" - shaped hole faces forward or backward. The grounding through hole 14 includes a narrower portion 142 and wider portions 141 located on the left and right sides of the narrower portion 142. The part of the upper shielding sheet 1 between the two wider portions 141 is the pressing arm. When processing the grounding through hole 14, the pressing portion 11 can be processed together, which is convenient for processing and beneficial to improving processing efficiency.

[0063] In other specific embodiments, the grounding through hole 14 is a rectangular hole, and the lower end of the rectangular hole is used to press the upper grounding spring claw 21 downward; alternatively, a pressing block (or pressing rod) is provided on the upper surface of the upper shielding sheet 1, and one end of the pressing block (or pressing rod) is located directly above the grounding through hole 14 and forms the pressing portion 11; alternatively, a pressing block (or pressing rod) is provided on the lower surface of the upper shielding sheet 1, and one end of the pressing block (or pressing rod) is located directly below the grounding through hole 14 and forms the pressing portion 11.

[0064] As Figures 1 - 10 shown, in a specific embodiment, a side - grounding structure is further provided on the upper shielding sheet 1. The side - grounding structure can be a side - grounding spring claw 12, a side - grounding convex hull, a side - grounding buckle, etc. By setting the side - grounding structure, the contact area and the number of contact points between the upper shielding sheet 1 and the cable shielding layer 311 can be increased, thereby further improving the shielding effect.

[0065] Of course, in other specific embodiments, the side - grounding structure can also be provided on the lower shielding sheet 4.

[0066] In the present invention, the side - grounding structure is the side - grounding spring claw 12. The side - grounding spring claw 12 includes a connecting portion and contact portions located on the front and rear sides of the connecting portion. Each side - grounding spring claw 12 has two contact points with the cable shielding layer 311, thereby further increasing the contact area and the number of contact points between the shielding sheet and the cable shielding layer 311. At the same time, the side - grounding spring claw 12 with front and rear two contact points can also straighten the cable 31.

[0067] Preferably, the side - grounding spring claw 12 is provided on the upper shielding sheet 1. At this time, the side - grounding spring claw 12 and the upper shielding sheet 1 can be formed from the same flat plate, and the raw material utilization rate is high. At this time, the upper shielding sheet 1 is electrically connected to the cable shielding layer 311 through both the side - grounding spring claw 12 and the conductive adjusting piece 2; of course, when the side - grounding spring claw 12 is processed separately, the side - grounding spring claw 12 can also be fixedly connected to the lower shielding sheet 4 by welding or other means.

[0068] It should be specifically noted that in other specific embodiments, the lower shielding piece 4 includes a grounding through hole 14 and a pressing portion 11. The grounding spring claw is a lower grounding spring claw. The lower grounding spring claw passes through the grounding through hole 14, and the pressing portion 11 is used to press the lower grounding spring claw upward. By moving the conductive adjusting piece 2 (i.e., moving the lower grounding spring claw), the deformation degree of the lower grounding spring claw is adjusted. After the lower grounding spring claw and the upper contact structure clamp the cable shielding layer 311, the adjusting piece body 22 is fixedly connected to the lower surface of the lower shielding piece 4.

[0069] Specific embodiments of the cable connector provided by the present invention: The cable connector includes a housing and at least two cable assemblies mounted on the housing. The number of cable assemblies is specifically two, three, four or more, and the cable assemblies are any one of the cable assemblies in the specific embodiments of the cable assemblies of the present invention. The installation method of the housing and the cable assemblies can refer to the Chinese patent application with the application publication number CN119070085A, which will not be elaborated here.

[0070] Specific embodiments of the manufacturing method of the cable assembly provided by the present invention: The cable assembly manufactured by using the manufacturing method of the cable assembly of the present invention is any one of the cable assemblies in the specific embodiments of the cable assemblies of the present invention.

[0071] Referring to Figures 1 - 10 As shown, the manufacturing method of the cable assembly of the present invention includes the process of respectively installing the upper and lower shielding pieces on the insulator. One of the upper and lower shielding pieces is provided with a contact structure, and the other includes a grounding through hole 14 and a pressing portion 11. After the upper and lower shielding pieces are installed on both sides of the insulator, the conductive adjusting piece installation step is performed. In the conductive adjusting piece installation step, first, the grounding spring claw of the conductive adjusting piece 2 passes through the grounding through hole 14 and is pressed by the pressing portion 11 against the cable shielding layer 311 of the cable 31. Then, the conductive adjusting piece 2 is moved to adjust the deformation degree of the grounding spring claw until the grounding spring claw and the contact structure clamp the cable shielding layer 311. Finally, the conductive adjusting piece 2 is fixed on the shielding piece provided with the grounding through hole 14.

[0072] Specifically, the manufacturing method of the cable assembly includes a shielding piece assembly step and a conductive adjusting piece installation step executed in sequence. Among them, the specific process of the shielding piece assembly step is: first, the pin component and the cable 31 are electrically connected by means of welding or conductive adhesive bonding, etc. Then, the cable 31 (or the cable module 3) and the lower shielding piece 4 are assembled together (wherein, the cable 31 is provided with an insulator, the cable module 3 includes an insulator, the insulator is provided with a riveting post, and the upper shielding piece 1 and the lower shielding piece 4 are provided with corresponding riveting holes), and the support plate 5 is installed. Finally, the upper shielding piece 1, the support plate 5 and the lower shielding piece 4 are welded together, and the shielding piece and the insulator are riveted and fixed.

[0073] In the present invention, the specific process of the shielding sheet assembly step is similar to that of the existing shielding sheet assembly step, except that: the structure of one of the shielding sheets (the shielding sheet having the grounding through hole 14) is different, so the final product obtained is different.

[0074] The main difference between the present invention and the prior art is that: in the prior art, when the cable 31, the upper shielding sheet 1, the support plate 5 and the lower shielding sheet 4 are assembled, the upper grounding spring claw 21 and the lower contact structure have already clamped the cable shielding layer 311, and the product formed at this time is a finished cable assembly; while in the present invention, after the shielding sheet assembly step is completed, the grounding spring claw has not yet contacted the cable shielding layer 311, and the product formed at this time is a semi-finished product; when the conductive adjusting sheet installation step is performed, the grounding spring claw just contacts the cable shielding layer 311. At the same time, by moving the conductive adjusting sheet 2, the distance between the grounding spring claw and the contact structure can be adjusted, so that the grounding spring claw and the contact structure can clamp more specifications of cables 31, expanding the range of cables applicable to the cable assembly.

[0075] To facilitate the understanding of the present invention by those skilled in the art, the present invention will still be introduced below by taking the upper shielding sheet 1 including the grounding through hole 14 as an example.

[0076] Preferably, one of the adjusting sheet body 22 and the upper shielding sheet 1 is connected with a slider 25, and the other is connected with a sliding part for guiding and slidingly cooperating with the slider 25 in the front-back direction. In the conductive adjusting sheet installation step, first make the slider 25 and the sliding part guide and slide in the front-back direction, and then move the conductive adjusting sheet 2 in the front-back direction, so as to avoid the relative movement between the conductive adjusting sheet 2 and the upper shielding sheet 1 having a lateral displacement in the left-right direction and avoid the left-right misalignment between the conductive adjusting sheet 2 and the upper shielding sheet 1.

[0077] In a specific embodiment, the upper shielding sheet 1 has a sliding cooperation section 15. Sliders 25 are provided on both the left and right sides of the adjusting sheet body 22. The distance between the left and right sliders 25 matches the left-right width of the sliding cooperation section 15, and the left and right side surfaces of the sliding cooperation section 15 constitute the sliding part.

[0078] In the conductive adjusting sheet installation step, first make the slider 25 guide and slide with the left and right side surfaces of the sliding cooperation section 15, and then move the conductive adjusting sheet 2 in the front-back direction.

[0079] In another specific embodiment, sliders 25 are provided on both the left and right sides of the upper shielding sheet 1. The distance between the left and right sliders 25 matches the left-right width of the adjusting sheet body 22, and the left and right side surfaces of the adjusting sheet body 22 constitute the sliding part.

[0080] In the step of installing the conductive adjusting piece, first make the slider 25 be in guiding sliding fit with the left and right side surfaces of the adjusting piece body 22, and then move the conductive adjusting piece 2 in the front-rear direction.

[0081] In yet another specific embodiment, a slider 25 is provided on one of the upper shielding piece 1 and the adjusting piece body 22, and a chute matching the slider 25 is provided on the other one. The chute extends in the front-rear direction. Among them, the chute is provided on the upper surface of the upper shielding piece 1 or the lower surface of the adjusting piece body 22. Correspondingly, the slider 25 is provided on the lower surface of the conductive adjusting piece 2 or the upper surface of the upper shielding piece 1.

[0082] In the step of installing the conductive adjusting piece, first make the chute and the slider 25 be in guiding sliding fit in the front-rear direction, and then move the conductive adjusting piece 2 in the front-rear direction.

[0083] In other specific embodiments, before the conductive adjusting piece 2 is fixedly connected to the upper shielding piece 1, the conductive adjusting piece 2 and the upper shielding piece 1 are not in guiding fit. When performing the step of installing the conductive adjusting piece, first insert the grounding spring claw into the grounding through hole 14 from above, and then move the conductive adjusting piece 2 in the left-right direction until the grounding spring claw clamps the cable with the contact structure. Finally, fixedly connect the adjusting piece body 22 to the upper surface of the upper shielding piece 1. When moving the conductive adjusting piece 2 in the front-rear direction, it is necessary to keep the conductive adjusting piece 2 aligned with the upper shielding piece 1 to avoid misalignment between the conductive adjusting piece 2 and the upper shielding piece 1.

[0084] It should be specifically noted that when the lower shielding piece 4 includes the grounding through hole 14, when performing the step of installing the conductive adjusting piece, first insert the grounding spring claw into the grounding through hole 14 from below, and then move the conductive adjusting piece 2 in the left-right direction until the grounding spring claw clamps the cable with the contact structure. Finally, fixedly connect the adjusting piece body 22 to the lower surface of the lower shielding piece 4.

[0085] Finally, it should be noted that the above are only the preferred embodiments of the present invention and are not used to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, for those skilled in the art, they can still make modifications to the technical solutions recorded in the foregoing embodiments without creative efforts, or perform equivalent replacements for some of the technical features, or organically combine different specific embodiments, so as to combine the specific embodiments given in the appendix Figures 1 - 10 Among them. Of course, those skilled in the art can also combine the specific embodiments not given in the remaining specification drawings. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included within the protection scope of the present invention.
