Description

Technical Field

[0001] This utility model relates to the field of connectors, and more particularly to a shielding bracket and a heavy-duty connector assembly. Background Technology

[0002] Currently, in heavy-duty connectors, the shielding bracket for securing the shielded wire includes a connecting frame attached to the connector and a fixed-shape clamp. When securing shielded wires of different diameters, clamps bent into different sizes must be selected. Different sized clamps are suitable for securing shielded wires of different diameters, with approximately a 1mm gap between the two sizes. This can lead to clamps that are too large or too small. For example, when securing a 6.7mm diameter shielded wire, a 7mm clamp may not provide a tight grip, while a 6mm clamp might damage the shielded wire. Furthermore, a fixed-size clamp is clearly unsuitable for situations requiring the clamping and securing of different numbers of shielded wires. Utility Model Content

[0003] This utility model provides a shielding bracket and a heavy-duty connector assembly, the purpose of which is to solve the problem that existing shielding brackets cannot flexibly adapt to situations where different sizes and / or numbers of shielded wires need to be clamped and fixed.

[0004] To achieve the above objectives, this utility model provides a shielding bracket for connecting to a heavy-duty connector to fix the shielded wire. The bracket includes a support and a sliding block. The support includes two opposing support columns and a connecting portion connecting the two support columns. Both support columns extend along the height direction of the support. The sliding block is disposed between the two support columns and slidably connected to the two support columns along the height direction of the support. An adjustment structure is provided between the support and the sliding block for adjusting the position of the sliding block relative to the support along the height direction of the support. The connecting block, the connecting portion, and the two support columns enclose a clamping space for the shielded wire to pass through.

[0005] As a further improvement of this utility model, the support has a first arc surface on the side facing the clamping space, and the sliding block has a second arc surface on the side facing the clamping space, with the protrusion directions of the first arc surface and the second arc surface being opposite.

[0006] As a further improvement of this utility model, each of the two support columns is provided with a sliding groove extending along the height direction of the support, and the two sliding grooves are open on their adjacent sides. The sliding block includes two sliding parts located in the two sliding grooves respectively.

[0007] As a further improvement of this utility model, the adjustment structure includes a screw, a threaded hole in the sliding part, and a through hole in the support. The threaded hole and the through hole are coaxially arranged and their axes extend along the height direction of the support. The screw includes a stud portion that passes through the through hole and is threaded to the threaded hole, and a screw head that is connected to one end of the stud portion and used to press against the support. The stud portion does not extend beyond the side of the support portion near the clamping space.

[0008] As a further improvement of this utility model, the shielding bracket also includes a connecting frame for connecting a heavy-duty connector, and the side of the connecting part opposite to the sliding block is attached to the connecting frame.

[0009] As a further improvement of this utility model, the shielding bracket includes a first support and a second support, a first sliding block and a second sliding block. The first support and the second support are respectively located on opposite sides of the connecting frame. The first sliding block is disposed between the two support pillars of the first support and is slidably connected to the two support pillars of the first support along the height direction of the first support. The second sliding block is disposed between the two support pillars of the second support and is slidably connected to the two support pillars of the second support along the height direction of the second support.

[0010] As a further improvement of this utility model, the shielding bracket also includes a fastening structure connecting the first support, the second support and the connecting frame. The fastening structure includes a column portion passing through the first support, the second support and the connecting frame, and two pressure heads connected to the column portion. The pressure heads respectively abut against the side of the first support away from the connecting frame and the side of the second support away from the connecting frame.

[0011] As a further improvement of this utility model, the connecting frame includes a main body and two support legs respectively connected to both sides of the main body. The support is located on one side of the main body, and each of the two support legs has a connection structure for connecting to a heavy-duty connector at the end away from the main body.

[0012] As a further improvement of this utility model, the ratio of the width to the height of the first arc surface is at least 4:1, and the ratio of the width to the height of the second arc surface is at least 4:1.

[0013] This utility model also provides a heavy-duty connector assembly, which includes a heavy-duty connector and the aforementioned shielding bracket connected to the heavy-duty connector.

[0014] Beneficial effects: In the shielding bracket and heavy-duty connector assembly provided by this utility model, the sliding block, the connecting part, and the two support parts form a clamping space for the shielded wire to pass through. Under the action of the adjustment structure, the height of the clamping space can be adjusted as needed so that shielded wires of different sizes and / or numbers can pass through the clamping space.

Detailed Implementation

[0017] The present invention will now be described in detail with reference to the embodiments shown in the accompanying drawings. However, these embodiments do not limit the present invention, and any modifications to the mechanism, method, or function made by those skilled in the art based on these embodiments are included within the protection scope of the present invention.

[0018] The terms used herein, such as "up," "down," "left," "right," "front," and "back," indicating spatial relative position, are for illustrative purposes to describe the relationship of one feature relative to another, as shown in the accompanying drawings. It is understood that, depending on the product's placement, these terms may be intended to include different orientations besides those shown in the figures, and should not be construed as limiting the claims. Furthermore, the descriptive term "horizontal" used herein is not entirely equivalent to being perpendicular to the direction of gravity, and allows for a certain angle of inclination.

[0019] like Figure 1 As shown, one embodiment of this utility model provides a heavy-duty connector assembly 100. The heavy-duty connector assembly 100 includes a heavy-duty connector 101 and a shielding bracket 102. The shielding bracket 102 is connected to the heavy-duty connector 101 and is used to secure a shielded cable. The shielding bracket 102 is grounded, thus guiding external interference signals to the ground terminal, thereby preventing external interference signals from affecting signal transmission in the heavy-duty connector 101. In this document, the shielded cable is referred to as a shielded cable 200.

[0020] Continue to combine Figure 2-4 As shown, the shielding bracket 102 includes a support 10 and a sliding block 20. The support 10 includes two opposing support columns 11 and a connecting portion 12 connecting the two support columns 11. Both support columns 11 extend along the height direction of the support 10. The sliding block 20 is disposed between the two support columns 11 and is slidably connected to the two support columns 11 along the height direction of the support 10. It can be seen that the two support columns 11 are arranged opposite each other along the width direction of the support 10.

[0021] It should be noted that in this article, the height direction of support 10 is when support 10 is in the direction of... Figure 2 In the described state, the vertical direction and the width direction of the support 10 are such that the support 10 is in the vertical direction. Figure 2 The left and right directions in the state shown.

[0022] The two support sections 11 and the connecting section 12 are integrally formed. The support 10 can be made from the same piece of material through a process such as cutting to remove material.

[0023] In this embodiment, the sliding block 20, the connecting portion 12, and the two support portions 11 form a clamping space 40 for the shielding wire 200 to pass through. When the shielding bracket 102 fixes the shielding wire 200, the shielding wire 200 passes through the clamping space 40 formed by the sliding block 20, the connecting portion 12, and the two support portions 11. The sliding block 20, the connecting portion 12, and the two support portions 11 can all contact the shielding wire 200, thereby jointly clamping and fixing the shielding wire 200.

[0024] An adjustment structure 30 is provided between the support 10 and the sliding block 20. The adjustment structure 30 is used to adjust the position of the sliding block 20 relative to the support 10 along the height direction of the support 10. Under the action of the adjustment structure 30, the position of the sliding block 20 can change relative to the support 10 along the height direction of the support 10. In this way, the height of the clamping space 40 can also change with the movement of the sliding block 20, so that shielding wires 200 of different sizes and / or numbers can pass through the clamping space 40, and the shielding bracket 102 can adaptively clamp and fix shielding wires 200 of different sizes and / or numbers. The above-mentioned "adjustment structure 30 is used to adjust the position of the sliding block 20 relative to the support 10 along the height direction of the support 10" can be specifically understood as the adjustment structure 30 enabling the relative position of the support 10 and the sliding block 20 to change in the height direction of the support 10.

[0025] It is conceivable that if the width of the clamping space 40 is greater than the diameter of the shielding wire 200, multiple shielding wires 200 arranged side by side can pass through the clamping space 40 (e.g., Figure 2 As shown, the sliding block 20, the connecting part 12, and the two support parts 11 can jointly clamp and fix multiple shielded wires 200 arranged side by side.

[0026] In summary, in the shielding bracket 102 provided in this embodiment, the sliding block 20, the connecting part 12, and the two support parts 11 form a clamping space 40 for the shielding wire 200 to pass through. Under the action of the adjusting structure 30, the height of the clamping space 40 can be adjusted as needed so that shielding wires 200 of different sizes and / or numbers can pass through the clamping space 40. Thus, the sliding block 20, the connecting part 12, and the two support parts 11 can reliably clamp and fix shielding wires 200 of different sizes and / or numbers. The shielding bracket 102 can flexibly adapt to working requirements and can fix and clamp a sufficient number of shielding wires 200.

[0027] The support 10 and the sliding block 20 may be made of copper (pure copper or copper alloy), which has good conductivity, so as to reduce the resistance of the shielding circuit on the heavy-duty connector assembly 100 and give the heavy-duty connector assembly better anti-interference performance.

[0028] In this embodiment, the support 10 has a first arc surface 13 on the side facing the clamping space 40, and the sliding block 20 has a second arc surface 21 on the side facing the clamping space 40. The first arc surface 13 and the second arc surface 21 are arranged opposite to each other along the height direction of the support 10. The protrusion directions of the first arc surface 13 and the second arc surface 21 are opposite.

[0029] Since the cross-section of the shielding wire 200 is generally circular, and it is provided with a first arc surface 13 and a second arc surface 21, the sliding block 20 and the support 10 can better contact shielding wires 200 of different diameters. When the first arc surface 13 and the second arc surface 21 are not a complete semicircle (a complete semicircle is an arc surface whose width is equal to twice its height), when multiple shielding wires 200 are parallel to each other pass through the clamping space 40, the sliding block 20 and the support 10 can make good contact with the multiple shielding wires 200 parallel to each other.

[0030] Both support columns 11 are provided with grooves 14 extending along the height direction of the support 10. The two adjacent sides of the two grooves 14 are open. The sliding block 20 includes two sliding parts 22 located in the two grooves 14 respectively. The two adjacent sides of the two grooves 14 are open, so that the two sliding parts 22 can enter the two grooves 14 respectively. The two sliding parts 22 slide in the two grooves 14 respectively, so that the sliding block 20 can slide stably along the height direction of the support 10.

[0031] It can be seen that the dimension occupied by the sliding block 20 in the width direction of the support 10 is larger than the dimension occupied by the clamping space 40 in the width direction of the support 10. In this embodiment, the slide groove 14 extends to the end of the support column 11 away from the connecting part 12 along the height direction of the support 10, so that the two sliding parts 22 can enter the two slide grooves 14 respectively along the height direction of the support 10.

[0032] To enable the two sliding parts 22 to move into the two sliding grooves 14 respectively, other designs can be adopted. For example, in other embodiments of this utility model, the sliding block 20 includes a separable first part and a second part, each of which includes a sliding part 22. In specific installation, the first part and the second part are separated first, and after the two sliding parts 22 enter the two sliding grooves 14 respectively, the first part and the second part are connected together.

[0033] In this embodiment, the adjustment structure 30 includes a screw 31, a threaded hole 32 in the sliding portion 22, and a through hole 33 in the support 10. The threaded hole 32 and the through hole 33 are coaxially arranged, and their axes extend along the height direction of the support 10. The screw 31 includes a stud portion 311 and a screw head 312 connected to one end of the stud portion 311. The stud portion 311 passes through the through hole 33 and is threadedly connected to the threaded hole 32. The screw head 312 is used to abut against the support 10. The diameter of the screw head 312 is larger than the diameter of the stud portion 311.

[0034] Tightening screw 31 changes the relative position of sliding block 20 and support 10 along the height of support 10, allowing shielding wires 200 of different sizes and / or quantities to pass through clamping space 40. When shielding wire 200 passes through clamping space 40, tightening screw 31 causes sliding block to press shielding wire 200, thus fixing shielding wire 200 in place. When it is necessary to loosen shielding wire 200, simply loosen screw 31.

[0035] In this embodiment, the stud portion 311 does not extend beyond the side of the support portion 11 closest to the clamping space 40. Thus, when the shielding wire 200 passes through the clamping space 40, the stud portion 311 will not contact the shielding wire 200, but the support portion 11 will be able to contact the shielding wire 200. This allows the two support portions 11, the connecting portion 12, and the sliding block 20 to clamp and fix the shielding wire 200.

[0036] In this embodiment, two adjustment structures 30 are provided between the sliding block 20 and the support 10, and the two adjustment structures 30 are respectively located on both sides of the support 10 in the width direction. The arrangement of the two adjustment structures 30 enables the shielding bracket 102 to more effectively fix shielding wires 200 of different sizes and / or numbers.

[0037] In other embodiments of this utility model, the positions of the through hole 33 and the screw hole can be interchanged, that is, the through hole 33 is opened in the sliding part 22, and the threaded hole 32 is opened in the support 10. In this case, the screw head 312 is used to press against the sliding part 22.

[0038] The shielding bracket 102 also includes a connecting frame 50 for connecting the heavy-duty connector 101, to which the aforementioned support 10 is connected. Specifically, the side of the connecting portion 12 facing away from the sliding block 20 is fitted against the connecting frame 50. The support 10 is connected to the heavy-duty connector 101 via the connecting frame 50, and can be positioned appropriately relative to the heavy-duty connector 101.

[0039] The shielding bracket 102 also includes a fastening structure 60, which connects the support 10 and the connecting frame 50, so that the support 10 and the connecting frame 50 can be fixed together.

[0040] The fastening structure 60 includes a connecting post 61 passing through the support 10 and the connecting frame 50, and two pressure heads 62 connected to the connecting post 61. The two pressure heads 62 respectively press the support 10 and the connecting frame 50, thereby fixing the support 10 to the connecting frame 50. To ensure the reliability of the connection between the support 10 and the connecting frame 50, in this embodiment, two fastening structures 60 are provided along the width direction of the support 10.

[0041] Specifically, the fastening structure 60 includes a screw and a nut, the connecting post 61 is the shank of the screw, and of the two pressure heads 62, one is the screw head and the other is a nut threaded onto the shank. The support 10 has a first connecting hole 15 for the connecting post 61 to pass through, and the connecting frame 50 has a second connecting hole 54 for the connecting post 61 to pass through.

[0042] like Figure 5 As shown, in another embodiment of this utility model, the shielding bracket 102 includes two supports 10 and a second sliding block 20b. The two supports 10 are respectively a first support 10a and a second support 10b, and the two sliding blocks 20 are respectively a first sliding block 20a and a second sliding block 20b. The first support 10a and the second support 10b are respectively located on opposite sides of the connecting frame 50. The first sliding block 20a is disposed between the two support pillars 11 of the first support 10a and is slidably connected to the two support pillars 11 of the first support 10a along the height direction of the first support pillars 11. The second sliding block 20b is disposed between the two support pillars 11 of the second support 10b and is slidably connected to the two support pillars 11 of the second support 10b along the height direction of the second support 10b.

[0043] With two supports 10 and sliding blocks 20 that cooperate with the two supports 10 respectively, the shielding bracket 102 can clamp and fix a larger number of shielding wires 200. It is conceivable that an adjustment structure 30 is provided between the first support 10a and the first sliding block 20a, and an adjustment structure 30 is also provided between the second support 10b and the second sliding block 20b.

[0044] The shielding bracket 102 also includes a fastening structure 60, which connects the first support 10a, the second support 10b and the connecting frame 50, so that the first support 10a, the second support 10b and the connecting frame 50 can be fixed together.

[0045] The fastening structure 60 includes a connecting post 61 passing through the first support 10a, the second support 10b, and the connecting frame 50, and two pressure heads 62 connected to the connecting post 61. One of the two pressure heads 62 presses the side of the first support 10a away from the connecting frame 50, and the other presses the side of the second support 10b away from the connecting frame 50. The two pressure heads 62 can press the first support 10a and the second support 10b onto the connecting frame 50 respectively.

[0046] Specifically, the fastening structure 60 includes a screw and a nut. The connecting post 61 is the screw shank, and of the two pressure heads 62, one is the screw head, and the other is the nut threaded onto the screw shank. Both supports 10 are provided with a first connecting hole 15 for the connecting post 61 to pass through, and the connecting frame 50 is provided with a second connecting hole 54 for the connecting post 61 to pass through.

[0047] like Figure 6 As shown, the connecting frame 50 includes a main body 51, two support legs 52 respectively connected to both sides of the main body 51, and a support 10 specifically connected to the main body 51. The second connecting hole 54 is formed on the main body 51.

[0048] Each of the two support legs 52 has a connection structure 53 at the end away from the main body 51 for connecting to the heavy-duty connector 101. The connecting bracket 50 can be connected to the heavy-duty connector 101 through the connection structure 53 on the support leg. The connection structure 53 can be a through hole 33 for screws to pass through, and the connecting bracket 50 is connected to the heavy-duty connector 101 by screws.

[0049] Specifically, the heavy-duty connector 101 includes a housing 1011, a bracket 1012 connected to the housing 1011, and a pin module 1013 connected to the bracket 1012. Two legs 52 are connected to the bracket 1012 via a connecting structure 53.

[0050] In this embodiment, the width-to-height ratio of the first arc surface 13 is at least 4:1, and the width-to-height ratio of the second arc surface 21 is at least 4:1. The width of the first arc surface 13 is its dimension in the width direction of the support 10, and its height is its dimension in the height direction of the support 10. The width of the second arc surface 21 is its dimension in the width direction of the support 10, and its height is its dimension in the height direction of the support 10.

[0051] With the above configuration, when multiple shielded wires 200 pass through the clamping space 40, the first arc surface 13 and the second arc surface 21 can fit the multiple shielded wires 200 well.

[0052] In other embodiments of this utility model, the ratio of the width to the height of the first arc surface 13 can be at least 3:1 or 5:1, and the ratio of the width to the height of the second arc surface 21 can be at least 3:1 or 5:1.

[0053] It should be understood that although this specification describes embodiments, not every embodiment contains only one independent technical solution. This way of describing the specification is only for clarity. Those skilled in the art should regard the specification as a whole. The technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.

[0054] The above embodiments are only used to illustrate the technical solutions of this application and are not intended to limit it. Although this application has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of this application without departing from the spirit and scope of the technical solutions of this application.
