Abstract
Description
Technical Field
[0001] The present invention belongs to the field of connecting devices, and particularly relates to a cable assembly, a cable connector, and a manufacturing method of the cable assembly. 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 piece and a lower shielding piece. One end of the cable is located between the upper and lower shielding pieces. The upper shielding piece is provided with an upper contact structure for pressing down on the cable shielding layer, and the lower shielding piece is provided with a lower contact structure for pressing up on the cable shielding layer. 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 shielding piece and the lower shielding piece and the cable shielding layer. Preferably, the upper contact structure is an upper grounding spring claw, which can enable the upper and lower contact structures to clamp more cable specifications.
[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 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 simultaneously, and thus cannot clamp the cable. Therefore, the above cable shielding and grounding structure cannot be applied to cables with smaller specifications, and its application 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 above-mentioned technical problem.

A contact structure in contact with the cable shielding layer is provided on one of the upper shielding sheet and the lower shielding sheet, and a grounding spring claw for pressing against the cable shielding layer is provided on the other. The contact structure and the grounding spring claw are vertically corresponding. The cable assembly further includes a pressing sheet for pressing the grounding spring claw to deform it towards the cable shielding layer. The pressing 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.
[0009] Furthermore, a slider is connected to one of the shielding sheet provided with the grounding spring claw and the pressing sheet, and the other has a sliding portion. The slider and the sliding portion are used for guiding and moving in the front-rear direction before the pressing sheet is fixedly connected to the shielding sheet provided with the grounding spring claw to adjust the deformation degree of the grounding spring claw.
[0010] Furthermore, the shielding sheet provided with the grounding spring claw has a sliding fit section. Sliders are provided on both the left and right sides of the pressing sheet. 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 respectively constitute the sliding portions.
[0011] Furthermore, the shielding sheet provided with the grounding spring claw 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 out of the sliding fit section to form notches, and the sliders are located in the notches.
[0012] Furthermore, sliders are provided on both the left and right sides of the shielding sheet provided with the grounding spring claw. The distance between the sliders on the left and right sides matches the left and right widths of the pressing sheet. The left and right side surfaces of the pressing sheet respectively constitute the sliding portions.
[0013] Furthermore, the pressing sheet includes a pressing sheet body and elastic support arms provided on the opposite sides of the pressing sheet body. One end of the elastic support arm is connected to the pressing sheet body, and the other end is fixedly connected to the shielding sheet provided with the grounding spring claw. The elastic support arm is used to elastically deform before being fixedly connected to the shielding sheet provided with the grounding spring claw to adjust the deformation degree of the grounding spring claw, and the elastic support arm is used to keep its shape unchanged after being fixedly connected to the shielding sheet provided with the grounding spring claw.
[0014] Furthermore, the shielding sheet provided with the grounding spring claw includes a shielding sheet body and elastic support arms provided on the shielding sheet body. The pressing sheet is fixedly connected to the elastic support arm. The elastic support arm is used to elastically deform before being fixedly connected to the pressing sheet to adjust the deformation degree of the grounding spring claw, and the elastic support arm is used to keep its shape unchanged after being fixedly connected to the pressing sheet.
[0015] Further, the pressing piece includes a pressing piece body and a pressing block connected to the pressing piece body. The pressing block has a pressing portion protruding from the pressing piece body and used for pressing the grounding elastic claw.
[0016] Further, at least two cables are arranged at intervals in the left - right direction. The grounding elastic claws corresponding in the left - right direction are arranged in rows, and the number of grounding elastic claws in each row is the same as the number of cables. There is at least one row of grounding elastic claws in the front - back direction, and the number of pressing pieces is equal to the number of rows of grounding elastic claws. Each pressing piece is respectively used for pressing the grounding elastic claws in the corresponding row.
[0017] The beneficial effects of the cable assembly of the present invention are as follows: The present invention is an improved invention. Compared with the prior art, the cable assembly in the present invention further includes a pressing piece. By pressing the grounding elastic claw with the pressing piece, the distance between the grounding elastic claw and the contact structure can be reduced, so as to adapt to more specifications of cables.
[0018] The following takes two types of large and small cables as examples to introduce the differences between the present invention and the prior art in detail: (1) For large - sized cables: In the prior art, the grounding elastic claw and the contact structure can clamp the cable, but the clamping force is small; in the present invention, the pressing piece presses the grounding elastic claw, thereby increasing the clamping force of the grounding elastic claw and the contact structure on the cable, so that the cable is fixed more firmly. (2) For small - sized cables: In the prior art, the grounding elastic claw and the contact structure cannot clamp the cable; in the present invention, the pressing piece presses the grounding elastic claw, thereby reducing the distance between the grounding elastic claw and the contact structure, so that the grounding elastic claw and the contact structure clamp the cable.
[0019] To achieve the above - mentioned purpose, the technical solution of the cable connector provided by the present invention is: A cable connector includes a housing and at least two cable assemblies installed on the housing. The cable assembly includes an upper shielding piece, a lower shielding piece, and a cable with one end located between the upper and lower shielding pieces. The cable has a cable shielding layer. A contact structure in contact with the cable shielding layer is provided on one of the upper shielding piece and the lower shielding piece, and a grounding elastic claw for pressing the cable shielding layer is provided on the other. The contact structure and the grounding elastic claw are vertically corresponding. The cable assembly further includes a pressing piece for pressing the grounding elastic claw to deform it towards the cable shielding layer. The pressing piece is used to move during the assembly of the cable assembly to adjust the deformation degree of the grounding elastic claw, and is used to be fixedly connected to the corresponding shielding piece after the grounding elastic claw deforms until the cable shielding layer is clamped between the grounding elastic claw and the contact structure.
[0020] Further, a slider is connected to one of the shielding piece provided with the grounding elastic claw and the pressing piece, and the other has a sliding portion. The slider and the sliding portion are used for guiding and moving in cooperation in the front - back direction before the pressing piece is fixedly connected to the shielding piece provided with the grounding elastic claw to adjust the deformation degree of the grounding elastic claw.
[0021] Further, the shielding sheet provided with grounding spring claws has a sliding fit section. Sliders are provided on both the left and right sides of the pressing sheet. The distance between the sliders on the left and right sides matches the left and right widths of the sliding fit section, and the left and right side surfaces of the sliding fit section respectively constitute the sliding parts.
[0022] Further, the shielding sheet provided with grounding spring claws also has wider sections on the front and back sides of the sliding fit section. The left and right sides of the wider sections protrude out of the sliding fit section to form notches, and the sliders are located within the notches.
[0023] Further, sliders are provided on both the left and right sides of the shielding sheet provided with grounding spring claws. The distance between the sliders on the left and right sides matches the left and right widths of the pressing sheet, and the left and right side surfaces of the pressing sheet respectively constitute the sliding parts.
[0024] Further, the pressing sheet includes a pressing sheet body and elastic support arms provided on the opposite sides of the pressing sheet body. One end of the elastic support arm is connected to the pressing sheet body, and the other end is fixedly connected to the shielding sheet provided with grounding spring claws; the elastic support arm is used to undergo elastic deformation before being fixedly connected to the shielding sheet provided with grounding spring claws to adjust the deformation degree of the grounding spring claws, and the elastic support arm is used to maintain its shape unchanged after being fixedly connected to the shielding sheet provided with grounding spring claws.
[0025] Further, the shielding sheet provided with grounding spring claws includes a shielding sheet body and elastic support arms provided on the shielding sheet body. The pressing sheet is fixedly connected to the elastic support arms. The elastic support arms are used to undergo elastic deformation before being fixedly connected to the pressing sheet to adjust the deformation degree of the grounding spring claws, and the elastic support arms are used to maintain their shape unchanged after being fixedly connected to the pressing sheet.
[0026] Further, the pressing sheet includes a pressing sheet body and a top pressing block connected to the pressing sheet body. The top pressing block has a top pressing part that protrudes out of the pressing sheet body and is used to top press the grounding spring claws.
[0027] Further, at least two cables are arranged at intervals in the left - right direction. The corresponding grounding spring claws in the left - right direction are arranged in rows, and the number of grounding spring claws in each row is the same as the number of cables. There is at least one row of grounding spring claws in the front - back direction, and the number of pressing sheets is equal to the number of rows of grounding spring claws. Each pressing sheet is respectively used to top press the grounding spring claws in the corresponding row.
[0028] The beneficial effects of the cable connector of the present invention are as follows: The present invention is an improved invention. Compared with the prior art, the cable connector in the present invention further includes a pressing sheet. By using the pressing sheet to top press the grounding spring claws, the distance between the grounding spring claws and the contact structure can be reduced, so as to adapt to more specifications of cables and increase the number of cable connector specifications.
[0029] To achieve the above object, 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 upper and lower shielding sheets onto an insulator. One of the upper and lower shielding sheets is provided with a contact structure that contacts the cable shielding layer of the cable, and the other is provided with a grounding spring claw for pressing against the cable shielding layer. After the upper and lower shielding sheets are assembled with the insulator, a pressing sheet that can press against the grounding spring claw and cause it to deform towards the cable shielding layer is installed on the shielding sheet provided with the grounding spring claw. During installation, the deformation degree of the grounding spring claw is changed by moving the pressing sheet. When the grounding spring claw deforms until the cable shielding layer is clamped between the grounding spring claw and the contact structure, the pressing sheet is fixedly connected to the shielding sheet provided with the grounding spring claw.
[0030] The beneficial effect of the manufacturing method of the cable assembly of the present invention is as follows: The present invention is an improved invention. Compared with the prior art, in the present invention, the deformation degree of the grounding spring claw is changed by using the pressing sheet, thereby reducing the distance between the grounding spring claw and the contact structure, enabling the cable assembly to adapt to more cable specifications.

Detailed implementation manners
[0033] To solve the problems in the background art, the core inventive concept of the present invention is: using a pressing piece to press against a grounding spring claw, thereby adjusting the distance between the grounding spring claw and the contact structure to adapt to more cable specifications.
[0034] For the convenience of those skilled in the art to understand the present invention, the "up and down direction" is defined in the present invention, and the "up and down direction" is the same as the arrangement direction of the two shielding sheets. 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 sheets 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.
[0035] The following further describes the present invention in detail with reference to embodiments.
[0036] Specific Embodiment 1 of the cable assembly provided by the present invention: On the basis of referring to Figure 1 and as shown in Figures 2 - 13 , as a basic specific implementation manner, the cable assembly includes a cable shielding grounding structure 100 and a cable 5. The cable 5 has a cable shielding layer 51. The cable shielding grounding structure 100 includes an upper shielding sheet 1 and a lower shielding sheet 3. One end of the cable 5 is located between the upper and lower shielding sheets. A contact structure in contact with the cable shielding layer 51 is provided on one of the upper shielding sheet 1 and the lower shielding sheet 3, and a grounding spring claw for pressing the cable shielding layer 51 is provided on the other. The contact structure and the grounding spring claw are corresponding up and down. The cable assembly further includes a pressing sheet for pressing the grounding spring claw to deform it towards the cable shielding layer 51. The pressing 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 and the cable shielding layer 51 is clamped between the grounding spring claw and the contact structure.
[0037] The following takes the upper grounding spring claw 11 provided on the upper shielding sheet 1 as an example to introduce the present invention in detail.
[0038] An upper grounding spring claw 11 for pressing the cable shielding layer 51 downward is provided on the upper shielding sheet 1 (i.e., the shielding sheet provided with the grounding spring claw). A lower contact structure 31 for pressing the cable shielding layer 51 upward is provided on the lower shielding sheet 3. The upper grounding spring claw 11 and the lower contact structure 31 are corresponding up and down. The cable assembly further includes a pressing sheet (the pressing sheet is a part of the cable shielding grounding structure 100) for pressing the upper grounding spring claw 11 downward. The pressing sheet is used to move during the assembly of the cable assembly to adjust the deformation degree of the upper grounding spring claw 11, and is used to be fixedly connected to the upper shielding sheet 1 after the upper grounding spring claw 11 deforms and the cable shielding layer 51 is clamped between the upper grounding spring claw 11 and the lower contact structure 31.
[0039] Among them, the lower contact structure 31 can be a contact structure commonly used in cable assemblies such as a lower grounding spring claw, a lower grounding convex hull, etc. Preferably, the pressing sheet is provided with a welding hole 202, and the pressing sheet is fixed on the upper shielding sheet 1 by welding, which is convenient to operate and has high processing efficiency.
[0040] Compared with the prior art, the cable assembly in the present invention further includes a pressing piece. By pressing the upper grounding spring claw 11 downward with the pressing piece, the distance between the upper grounding spring claw 11 and the lower contact structure 31 can be reduced, so as to adapt to cables 5 of more specifications.
[0041] Taking cables 5 of two specifications, large and small, as examples, the differences between the present invention and the prior art are introduced in detail as follows: (1) For large-sized cables: In the prior art, the upper grounding spring claw 11 and the lower contact structure 31 can clamp the cable 5, but the clamping force is small; in the present invention, the pressing piece presses the upper grounding spring claw 11 downward, so as to increase the clamping force of the upper grounding spring claw 11 and the lower contact structure 31 on the cable 5, and make the cable 5 be fixed more firmly; (2) For small-sized cables: In the prior art, the upper grounding spring claw 11 and the lower contact structure 31 cannot clamp the cable 5; in the present invention, the pressing piece presses the upper grounding spring claw 11 downward, so as to reduce the distance between the upper grounding spring claw 11 and the lower contact structure 31, and make the upper grounding spring claw 11 and the lower contact structure 31 clamp the cable 5.
[0042] Refer to Figures 2 - 12 As shown, in a specific embodiment, a slider 201 is connected to one of the upper shielding piece 1 and the pressing piece, and the other has a sliding portion. The slider 201 and the sliding portion are used for guiding and moving in cooperation in the front-back direction along the front edge where the pressing piece is fixedly connected to the upper shielding piece 1, so as to adjust the deformation degree of the upper grounding spring claw 11. At the same time, relative movement in the left-right direction between the pressing piece and the upper shielding piece 1 can be avoided.
[0043] Preferably, as Figures 2 - 12 shown, the pressing piece (i.e., the first pressing piece 21) is provided with a slider 201, and the upper shielding piece 1 is provided with a sliding portion. The slider 201 and the sliding portion are used for guiding and sliding in cooperation in the front-back direction along the front edge where the pressing piece (i.e., the first pressing piece 21) is fixed, so as to adjust the deformation degree of the upper grounding spring claw 11, that is, adjust the amount of deformation of the upper grounding spring claw 11.
[0044] As Figures 2 - 12 shown, in a specific embodiment, the upper shielding piece 1 has a sliding fit section 13. Sliders 201 are provided on both the left and right sides of the pressing piece (i.e., the first pressing piece 21). The distance between the sliders 201 on the left and right sides matches the left and right widths of the sliding fit section 13. The left and right side surfaces of the sliding fit section 13 constitute the sliding portion, and the structure is simple.
[0045] Preferably, as Figures 2 - 12As shown, the upper shielding sheet 1 further has wider sections 16 located on the front and rear sides of the sliding fit section 13. The left and right sides of the wider sections 16 protrude beyond the sliding fit section 13 to form notches, and the slider 201 is located within the notches, thus not increasing the left - right dimension of the cable assembly.
[0046] In other specific embodiments, the left - right width of the wider section 16 is less than the left - right width of the pressing sheet (i.e., the first pressing sheet 21), and the left - right dimension of the cable assembly is larger; or, the left - right width of the upper shielding sheet 1 is always the same.
[0047] In other specific embodiments, chutes matching the slider 201 (the number can be one, two or more) can also be provided on the upper shielding sheet 1, and the chutes constitute the sliding part.
[0048] In other specific embodiments, referring to Figures 2 - 12 As shown, the slider 201 can also be provided on the upper shielding sheet 1. At this time, the sliding part is provided on the pressing sheet.
[0049] Among them, the installation positions of the slider 201 and the sliding part can be swapped. Referring to Figures 2 - 12 As shown, in a specific embodiment, sliders 201 are provided on both the left and right sides of the upper shielding sheet 1. The distance between the sliders 201 on the left and right sides matches the left - right width of the pressing sheet, and the left and right side surfaces of the pressing sheet constitute the sliding part, with a simple structure.
[0050] In other specific embodiments, chutes matching the slider 201 (the number can be one, two or more) can also be provided on the pressing sheet. At this time, the chutes constitute the sliding part.
[0051] By moving the pressing sheet back and forth, the deformation degree of the upper grounding spring claw 11 can be conveniently adjusted, so that the upper grounding spring claw 11 clamps the cable 5 with the lower contact structure 31; at the same time, since the slider 201 and the sliding part are in guiding sliding fit in the front - rear direction, the pressing sheet will not move laterally, facilitating the movement of the pressing sheet.
[0052] In different specific embodiments, there can be only the end of one cable 5 between the upper and lower shielding sheets, or there can be the ends of two, three or more cables 5.
[0053] In a specific embodiment, at least two cables 5 are arranged at intervals in the left - right direction. The corresponding upper grounding spring claws 11 in the left - right direction are arranged in rows, and the number of each row of upper grounding spring claws 11 is the same as the number of cables 5. The upper grounding spring claws 11 are provided with at least one row in the front - rear direction, and the number of pressing sheets is equal to the number of rows of the upper grounding spring claws 11. Each pressing sheet is used to press against the corresponding row of upper grounding spring claws 11.
[0054] Specifically, m cables 5 are arranged at intervals in the left - right direction between the upper and lower shielding sheets, where m≥2. Each cable 5 is provided with a corresponding upper grounding spring claw 11, and each upper grounding spring claw 11 is provided with a corresponding lower contact structure 31.
[0055] Among them, preferably, the upper grounding spring claws 11 are arranged in n rows in the front - back direction, where n≥2, so that the upper grounding spring claws 11 form an m - column×n - row matrix. The number of pressing sheets is n, and each pressing sheet is used to simultaneously press each row of upper grounding spring claws 11. At this time, n upper grounding spring claws 11 simultaneously press the same cable 5, thereby ensuring the reliability of the grounding shield and enabling the cable assembly to adapt to signal transmission work at higher speeds.
[0056] When there are m cables 5 between the upper and lower shielding sheets, preferably, in a specific embodiment, the m cables 5 are formed into a cable module 400 by injection molding, so that one end of all the cables 5 can be placed between the upper and lower shielding sheets simultaneously.
[0057] In Figures 2 - 12 In the shown specific embodiment, m = 4 and n = 2. However, in other specific embodiments, m can also be 2, 3, 5 or other numbers, and n can also be 3, 4 or other numbers.
[0058] In other specific embodiments, there is only one row of upper grounding spring claws 11, the number of pressing sheets is one, and the pressing sheet simultaneously presses all the upper grounding spring claws 11. At this time, each cable shielding layer 51 is in contact with one upper grounding spring claw 11.
[0059] It should be specifically noted that, as Figures 2 - 13 shown, the upper shielding sheet 1 has a first positioning hole 14, and the lower shielding sheet 3 has a second positioning hole 32. When assembling the upper shielding sheet 1, the lower shielding sheet 3, the cable module 400, the support plate 4 and the pin component 6 together, the positioning pin passes through the first positioning hole 14 and the second positioning hole 32 simultaneously to fix the relative positions of the upper shielding sheet 1 and the lower shielding sheet 3. Of course, a positioning pin can also be provided on one of the lower shielding sheet 3 or the upper shielding sheet 1, and a positioning hole can be provided on the other. Among them, when the number of cables 5 is at least two, the support plate 4 is also used to separate the pin components 6 connected to different cables 5.
[0060] In the present invention, to avoid interference between the pressing sheet and the positioning pin, an avoidance hole 203 for avoiding the positioning pin is also provided on the pressing sheet. When n≥2, the avoidance hole 203 can be provided on only one pressing sheet, or can be provided on all the pressing sheets. Preferably, the avoidance hole 203 is provided on all the pressing sheets, and there is no need to distinguish the types of pressing sheets when installing the pressing sheets, which is beneficial to on - site management.
[0061] The main improvement of the present invention lies in the pressing piece and the upper shielding piece 1. In the present invention, no improvements are made to the cable 5, the cable module 400, the lower shielding piece 3, the support plate 4, and the pin component 6. The difference between the upper shielding piece 1 in the present invention and the prior art is only that: there are side grounding claws 12 on the upper shielding piece 1. For the specific structures of the above components, reference can be made to the Chinese patent application with the application publication number CN115347406A and the Chinese patent application with the application publication number CN117080809A, which will not be elaborated here.
[0062] As Figures 4 - 13 shown, in a specific embodiment, a side grounding structure is further provided on the upper shielding piece 1. The side grounding structure can be structures such as side grounding claws 12, side grounding protrusions, and side grounding buckles. By setting the side grounding structure, the contact area and the number of contact points between the cable shielding grounding structure 100 and the cable shielding layer 51 can be increased, thereby further improving the shielding effect of the cable shielding grounding structure 100.
[0063] Of course, in other specific embodiments, the side grounding structure can also be provided on the lower shielding piece 3.
[0064] In the present invention, the side grounding structure is the side grounding claw 12. The side grounding claw 12 includes a connecting portion and contact portions located on the front and rear sides of the connecting portion. Each side grounding claw 12 has two contact points with the cable shielding layer 51, thereby further increasing the contact area and the number of contact points between the cable shielding grounding structure 100 and the cable shielding layer 51. At the same time, the side grounding claw 12 with front and rear contact points can also straighten the cable 5.
[0065] Preferably, the side grounding claw 12 is provided on the upper shielding piece 1. At this time, the side grounding claw 12, the upper grounding claw 11, and the upper shielding piece 1 can be formed by processing a single flat plate, with high raw material utilization rate; of course, when the side grounding claw 12 is processed separately, the side grounding claw 12 can also be fixedly connected to the lower shielding piece 3 by welding or other means.
[0066] It should be specifically noted that in other specific embodiments, before the pressing piece is fixedly connected to the upper shielding piece 1, the pressing piece and the upper shielding piece 1 are not in guiding cooperation. At this time, when the pressing piece is moved in the front-rear direction, it is necessary to keep the pressing piece and the upper shielding piece 1 aligned to avoid misalignment between the pressing piece and the upper shielding piece 1.
[0067] It should be specifically noted that the grounding claw can also be a lower grounding claw provided on the lower shielding piece 3, and the contact structure can be structures such as the upper grounding claw 11 and the upper grounding protrusion provided on the upper shielding piece 1. The pressing piece is used to upwardly press the lower grounding claw of the ground connection to shorten the distance between the lower grounding claw and the upper contact structure, which will not be elaborated here.
[0068] Specific Embodiment 2 of the cable assembly provided by the present invention: The purpose of this embodiment is to provide a cable assembly with a different pressing plate structure.
[0069] On the basis of referring to Figures 1 - 13 , as Figures 14 - 15 shown, the main difference between this embodiment and Specific Embodiment 1 is that in this embodiment, the pressing plate (i.e., the second pressing plate 22) further includes a pressing block 204.
[0070] Specifically, in this embodiment, the pressing plate (i.e., the second pressing plate 22) includes a pressing plate body 206 and a pressing block 204 connected to the pressing plate body 206. The pressing block 204 has a pressing portion that protrudes from the lower surface of the pressing plate body 206 and is used to press the upper grounding spring claw 11 downward.
[0071] By setting the pressing block 204, the gap between the upper grounding spring claw 11 and the lower contact structure 31 can be further reduced, so that the upper grounding spring claw 11 and the lower contact structure 31 can clamp a smaller specification cable 5.
[0072] When the pressing plate is fixedly connected to the lower shielding sheet 3, the pressing block 204 has a pressing portion that protrudes from the upper surface of the pressing plate body 206 and is used to press the lower grounding spring claw upward.
[0073] Specific Embodiment 3 of the cable assembly provided by the present invention: The purpose of this embodiment is to provide another cable assembly with a different pressing plate structure.
[0074] On the basis of referring to 1 - 15, as Figures 16 - 19 shown, the main differences between this embodiment and Specific Embodiment 1 and Specific Embodiment 2 are that in this embodiment, before the pressing plate is fixed, the pressing plate moves in the up - and - down direction.
[0075] Specifically, in this embodiment, the pressing plate (i.e., the third pressing plate 23) includes a pressing plate body 206 and first elastic support arms 205 arranged on opposite sides of the pressing plate body 206. One end of the first elastic support arm 205 is connected to the pressing plate body 206, and the other end is fixedly connected to the upper shielding sheet 1 to achieve the fixed connection between the pressing plate (i.e., the third pressing plate 23) and the upper shielding sheet 1; the first elastic support arm 205 is used to elastically deform before the first elastic support arm 205 is fixedly connected to the upper shielding sheet 1 to adjust the deformation degree of the upper grounding spring claw 11, and the first elastic support arm 205 is used to keep its shape unchanged after being fixedly connected to the upper shielding sheet 1.
[0076] Preferably, in the Figures 16 - 19 shown specific implementation manner, the first elastic support arms 205 are arranged on the front and rear sides of the pressing plate body 206. At this time, the number of the first elastic support arms 205 is relatively large, and the fixing effect is better.
[0077] However, in other specific embodiments, the first elastic arm 205 can also be arranged on the left and right sides of the tablet body.
[0078] When moving the tablet (i.e., the third tablet 23) downward, it is necessary to align the tablet (i.e., the third tablet 23) with the upper shielding sheet 1 to avoid misalignment between the tablet (i.e., the third tablet 23) and the upper shielding sheet 1.
[0079] In this embodiment, the tablet can also include a pressing block 204 arranged on the tablet body 206. The pressing block 204 has a pressing portion for pressing the upper grounding spring claw 11 downward. The pressing portion is located below the tablet body 206, so as to further reduce the distance between the upper grounding spring claw 11 and the lower contact structure 31.
[0080] It should be specifically noted that, in this embodiment, the structure of the upper shielding sheet 1 can be the same as that of the upper shielding sheet 1 in the specific embodiment 1 of the cable assembly of the present invention, that is, the upper shielding sheet 1 has a sliding fit section 13. At this time, this upper shielding sheet 1 can be applicable to both the process of horizontal sliding of the tablet and the process of up and down movement of the tablet. Of course, in this embodiment, the upper shielding sheet 1 may not have a sliding fit section 13. At this time, the upper shielding sheet 1 is more applicable to the process of up and down movement of the tablet.
[0081] Similarly, when the third tablet 23 is fixedly connected to the lower shielding sheet 3, the first elastic arm 205 can also be arranged on the lower shielding sheet 3. At this time, it is necessary to move the third tablet 23 upward to shorten the distance between the lower grounding spring claw and the upper contact structure, which will not be elaborated here.
[0082] Specific embodiment 4 of the cable assembly provided by the present invention: The purpose of this embodiment is to provide a cable assembly with different structures of the tablet and the upper shielding sheet.
[0083] On the basis of referring to Figures 1 - 19 and as shown in Figures 20 - 22 , the main differences between this embodiment and the specific embodiment 1 and the specific embodiment 2 are as follows: in this embodiment, before the tablet is fixed, the tablet moves in the up and down direction; the main difference between this embodiment and the specific embodiment 3 is that in the specific embodiment 3, the elastic structure (i.e., the first elastic arm 205) is arranged on the tablet body 206, while in this embodiment, the elastic structure (the second elastic arm 15) is arranged on the upper shielding sheet 1.
[0084] Specifically, the upper shielding sheet 1 includes an upper shielding sheet body and a second elastic arm 15 provided on the upper shielding sheet body. The pressing sheet (i.e., the fourth pressing sheet 24) is fixedly connected to the second elastic arm 15. The second elastic arm 15 is configured to elastically deform before being fixedly connected to the pressing sheet to adjust the deformation degree of the upper grounding elastic claw 11, and the second elastic arm 15 is configured to maintain its shape unchanged after being fixedly connected to the pressing sheet.
[0085] Specifically, since the pressing sheet is not an elastic member, after the second elastic arm 15 is fixedly connected to the pressing sheet, the second elastic arm 15 cannot drive the pressing sheet to deform, so the second elastic arm 15 cannot deform either. Therefore, the shape of the second elastic arm 15 does not change.
[0086] When moving the pressing sheet (i.e., the fourth pressing sheet 24) downward, it is necessary to align the pressing sheet (i.e., the fourth pressing sheet 24) with the upper shielding sheet 1 to avoid misalignment between the pressing sheet (i.e., the fourth pressing sheet 24) and the upper shielding sheet 1.
[0087] In this embodiment, the pressing sheet may also include a pressing sheet body 206 and a pressing block 204 provided on the pressing sheet body 206. The pressing block 204 has a pressing portion for pressing the upper grounding elastic claw 11 downward, and the pressing portion is located below the pressing sheet body 206, thereby further reducing the distance between the upper grounding elastic claw 11 and the lower contact structure 31.
[0088] Similarly, the fourth pressing sheet 24 may also be fixedly connected to the lower shielding sheet 3. At this time, it is necessary to move the fourth pressing sheet 4 upward, which will not be elaborated here.
[0089] Specific embodiments of the cable connector provided by the present invention: On the basis of referring to Figures 2 - 22 as shown in Figure 1 , the cable connector includes five cable assemblies, a housing 200, and a wire bundling sheet 300. The cable assemblies are installed on the housing 200, and the wire bundling sheet 300 is inserted into corresponding through holes on the housing 200 to fix the cable assemblies. According to specific requirements, the number of cable assemblies may also be one, two, or other numbers.
[0090] Among them, the specific structure of the cable assembly is the same as that of any one of the cable assemblies in the specific embodiments 1 to 4 of the cable assembly of the present invention. The technology of using the wire bundling sheet 300 to fix the housing 200 and the cable assembly can refer to the Chinese patent application with the publication number CN119070085A, which will not be elaborated here.
[0091] Specific embodiments of the manufacturing method of the cable assembly provided by the present invention: The cable assembly manufactured according to the manufacturing method of the cable assembly of the present invention is the cable assembly in the specific embodiments 1 to 4 of the cable assembly of the present invention.
[0092] Referring to Figures 1 - 22 as shown, the manufacturing method of the cable assembly includes the process of respectively installing upper and lower shielding sheets onto the insulator. One of the upper and lower shielding sheets is provided with a contact structure that contacts the cable shielding layer 51 of the cable 5, and the other is provided with a grounding spring claw for pressing against the cable shielding layer 51. After the upper and lower shielding sheets are assembled with the insulator, a pressing sheet that can press against the grounding spring claw and cause it to deform towards the cable shielding layer 51 is installed on the shielding sheet provided with the grounding spring claw. During installation, the deformation degree of the grounding spring claw is changed by moving the pressing sheet. When the grounding spring claw is deformed until the cable shielding layer 51 is clamped between the grounding spring claw and the contact structure, the pressing sheet is fixedly connected to the shielding sheet provided with the grounding spring claw.
[0093] Specifically, the manufacturing method of the cable assembly includes an assembling step of assembling the cable shielding grounding structure 100 with the cable 5, and the assembling step includes a shielding sheet assembling step and a pressing sheet installing step that are executed in sequence.
[0094] In the shielding sheet assembling step, first, the pin component 6 is electrically connected to the cable 5 by means such as welding or conductive adhesive bonding. After that, the cable 5 (or the cable module 400) is assembled with the lower shielding sheet 3 (wherein the cable 5 is configured with an insulator, the cable module 400 includes an insulator, the insulator is provided with riveting posts, and the upper shielding sheet 1 and the lower shielding sheet 3 are provided with corresponding riveting holes), and the support plate 4 is installed; finally, the upper shielding sheet 1, the support plate 4, and the lower shielding sheet 3 are welded together, and the shielding sheet is riveted to the insulator.
[0095] The pressing sheet installing step includes a pressing sub-step and a fixing sub-step that are executed in sequence. In the pressing sub-step, the pressing sheet is moved and the pressing sheet presses against the upper grounding spring claw 11 until the cable shielding layer 51 is clamped between the grounding spring claw and the contact structure. In the fixing sub-step, the pressing sheet is fixedly connected to the corresponding shielding sheet to form the cable assembly.
[0096] It should be specially noted that although the specific steps of the shielding sheet assembling step in the present invention are similar to the specific steps of the assembling step of assembling the cable shielding grounding structure 100 with the cable 5 in the prior art, however, in the shielding sheet assembling step, the cable shielding layer 51 may not be clamped by the grounding spring claw and the contact structure, while in the assembling step, the grounding spring claw and the contact structure must clamp the cable shielding layer 51.
[0097] Preferably, in the fixing sub-step, the pressing sheet is welded to the corresponding shielding sheet, which is convenient to operate and saves time.
[0098] In the present invention, after the shielding sheet assembly step, there is also a pressing sheet installation step. In the pressing sheet installation step, first, the pressing sheet presses against the grounding spring claw until the cable shielding layer 51 is clamped between the grounding spring claw and the contact structure, and then the pressing sheet is fixed to the shielding sheet. Thus, the pressing sheet in the cable assembly (finished product) is used to press against the grounding spring claw, ensuring that the cable shielding layers 51 of various specifications of cables are clamped between the grounding spring claw and the contact structure, and increasing the number of cable connector specifications.
[0099] Taking the fixed connection between the pressing sheet and the upper shielding sheet 1 as an example, in combination with the specific embodiments of the cable assembly of the present invention, the manufacturing method of the cable assembly of the present invention will be specifically described.
[0100] In the manufacturing method of the first type of cable assembly, a slider 201 is provided on one of the upper shielding sheet 1 and the pressing sheet, and the other has a sliding portion that is guidingly slidably engaged with the slider 201 in the front-rear direction; in the pressing sub-step, first, the slider 201 is guidingly slidably engaged with the sliding portion, and then the pressing sheet is moved in the front-rear direction to adjust the deformation degree of the upper grounding spring claw 11 until the cable shielding layer 51 is clamped between the upper grounding spring claw 11 and the lower contact structure 31.
[0101] According to the manufacturing method of the first type of cable assembly, the cable assemblies in Specific Embodiment 1 and Specific Embodiment 2 of the cable assembly of the present invention can be manufactured.
[0102] In the manufacturing method of the second type of cable assembly, there is no guiding cooperation between the upper shielding sheet 1 and the pressing sheet. In the pressing sub-step, the pressing sheet is directly moved in the front-rear direction until the cable shielding layer 51 is clamped between the upper grounding spring claw 11 and the lower contact structure 31.
[0103] In the manufacturing method of the third type of cable assembly, the pressing sheet includes a pressing sheet body 206 and first elastic arms 205 provided on opposite sides of the pressing sheet body 206. One end of the first elastic arm 205 is connected to the pressing sheet body 206. In the pressing sub-step, first, the other end of the first elastic arm 205 is brought into contact with the upper shielding sheet 1, and the pressing sheet body 206 is used to press down on the upper grounding spring claw 11. Then, the pressing sheet body 206 is pressed downward to adjust the deformation degree of the upper grounding spring claw 11 until the cable shielding layer 51 is clamped between the upper grounding spring claw 11 and the lower contact structure 31; in the fixing sub-step, the end of the first elastic arm 205 that is in contact with the upper shielding sheet 1 is fixedly connected to the upper shielding sheet 1 so that the first elastic arm 205 maintains its shape unchanged.
[0104] According to the manufacturing method of the third type of cable assembly, the cable assembly in Specific Embodiment 3 of the cable assembly of the present invention can be manufactured.
[0105] In the manufacturing method of the fourth cable assembly, the upper shielding sheet 1 includes an upper shielding sheet body and a second elastic arm 15 provided on the upper shielding sheet body. In the pressing sub-step, first, the pressing sheet simultaneously presses the second elastic arm 15 and the upper grounding spring claw 11 downward, and then, the pressing sheet is pressed downward to adjust the deformation degree of the upper grounding spring claw 11 until the cable shielding layer 51 is clamped between the upper grounding spring claw 11 and the lower contact structure 31; in the fixing sub-step, the second elastic arm 15 is fixedly connected to the pressing sheet so that the second elastic arm 15 maintains its shape unchanged.
[0106] According to the manufacturing method of the fourth cable assembly, the cable assembly in the specific embodiment 4 of the cable assembly of the present invention can be manufactured.
[0107] In the manufacturing methods of other cable assemblies, the pressing sheet can be fixedly connected to the lower shielding sheet 3, and the pressing sheet is used to press the lower grounding spring claw upward. According to the actual situation, the pressing sheet can be moved in the left-right direction, or the pressing sheet can be moved upward to adjust the distance between the lower grounding spring claw and the upper contact structure, which will not be elaborated here.
[0108] 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 make equivalent replacements for some of the technical features, or organically combine different specific implementation manners, so as to combine the Figures 1 - 22 specific implementation manners given in the appendix. Of course, those skilled in the art can also combine other specific implementation manners 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 in the protection scope of the present invention.
