Description

Technical Field

[0001] This disclosure relates to the field of mechanical fastening, and more specifically to a cable fastening device and cable fastening assembly for fastening cables to a plate-like structure. Background Technology

[0002] Cable clips have specific requirements when used to secure antenna cables. For example, ease of installation can be an issue. Existing standard cable clips require manual assistance to pre-fix the cable position before installation, making the process difficult. Space utilization is another concern. The main body of existing standard cable clips is concentrated on the back of the reflector, which is often unsuitable given the limited space behind current 5G equipment and conventional antennas. Reliability is also a concern. Existing cable clips secure both the cable and the clip itself, with the cable contributing little to the clip's stability. The size of the clip's latch arms is typically determined by the reflector's thickness, limiting the clamping strength and making the cable prone to detachment when subjected to external forces.

[0042] The embodiments of this disclosure will now be described in detail with reference to the accompanying drawings. The same or similar reference numerals in the drawings denote the same or similar elements or elements having the same or similar functions throughout the specification. It should be understood that the described embodiments are only some, not all, of the embodiments of this disclosure. All other embodiments obtained by those skilled in the art based on the embodiments of this disclosure without inventive effort are within the scope of protection of this disclosure.

[0043] The existing technology has the following technical problems. For example, ease of installation may be an issue. Existing ordinary cable clamps require manual assistance to pre-fix the cable position before installation, making the installation operation difficult. Furthermore, space utilization may be another problem. The main body of existing ordinary cable clamps is concentrated on the back of the reflector, which is often unsuitable given the very limited space behind current 5G equipment and ordinary antennas. In addition, reliability may be another issue. Existing cable clamps simultaneously fix both the cable and the clamp itself, with the cable not contributing to the clamp's fixation. The size of the clamp's latch arm is usually determined by the thickness of the reflector, limiting the fixing strength between the latch and the reflector, making the cable prone to detachment when the cable swings due to external forces.

[0044] To address the aforementioned technical issues, this disclosure proposes the following solutions:

[0045] Regarding the ease of installation: This disclosure improves the installation process of cable clamps. First, the cable clamp is inserted into the feature hole of the reflector, then the cable is embedded into the cable clamp; this step-by-step assembly is efficient and simple.

[0046] Regarding the issue of space utilization: This disclosure adopts a cable embedding fixing method, which effectively reduces the structure of the cable fixing part, thereby effectively saving the installation space on the back of the reflector. It breaks through the limit of the installation space of ordinary cable clamps and is very effective for 5G products with a back height requirement of less than 5mm.

[0047] Regarding reliability issues: In this disclosure, the cable clamp only needs to ensure the reliability of the fixation between the cable and the cable clamp, and the embedding of the cable can ensure that the cable clamp does not fall off the reflector.

[0048] During installation, the cable clamp is first secured by inserting it into the reflector plate, with the clamp's fixing part providing self-locking protection. After assembly, the cable clamp's fixing part is located on the front of the reflector plate. Even after the cable is inserted into the clamping structure, the clamping structure remains on the back of the reflector plate. The height of the clamping structure, still on the back of the plate-like structure, is only slightly larger than the cable diameter, maximizing space savings. Once the cable clamp is installed, the cable is held within it. The interference between the clamping structure and the cable causes deformation, generating a clamping force. Adjusting the deformation of the clamping structure ensures reliable cable fixation. The cable's insertion applies a reaction force to the clamping structure, reinforcing the fixing part and preventing the cable clamp from detaching from the reflector plate, thus ensuring reliable installation.

[0049] Through the above technical means, the cable fixing device of this disclosure can effectively save installation space and break through the installation space limit of ordinary cable clamps. In addition, the cable fixing device of this disclosure improves the installation process of cable clamps, making installation simple and convenient and improving efficiency. Moreover, the cable fixing device of this disclosure strengthens the fixing of the cable clamp itself while fixing the cable, and promotes a more secure and reliable overall fit by means of the reaction force of the cable. Furthermore, the cable fixing device of this disclosure has a high fault tolerance rate, which can reduce the impact of material shrinkage and dimensional deviation.

[0050] The cable fixing device provided in this disclosure will be described in detail below with reference to the accompanying drawings.

[0051] Figure 1 A front view of a cable securing device 100 according to an embodiment of the present disclosure is shown. As can be seen from the figure, the cable securing device 100 includes a first cantilever 110, which includes a first cantilever portion 112 for contacting a cable (not shown) to be secured, and a second cantilever portion 114 for securing the cable to be secured to a plate-like structure (not shown) connected to the cable securing device 100. Furthermore, the cable securing device 100 according to the present disclosure also includes a second cantilever 120, which includes a third cantilever portion 122 for contacting the cable (not shown) to be secured, and a fourth cantilever portion 124 for securing the cable to be secured to the plate-like structure (not shown), wherein the fourth cantilever portion 124 is connected to the second cantilever portion 114. Figure 1 As can be seen, the second cantilever portion 114 and the fourth cantilever portion 124 are connected via their lower ends. The first cantilever portion 112 and the third cantilever portion 122 are connected only via the second cantilever portion 114 and the fourth cantilever portion 124.

[0052] Figure 2 A schematic diagram is shown of a cable securing device 100, according to an embodiment of the present disclosure, being inserted into a plate-like structure 130. Figure 2 As can be seen from this, the cable fixing device 100 of this disclosure includes a first cantilever 110, which includes a first cantilever portion 112 for contacting the cable (not shown) to be fixed, and a second cantilever portion 114 for fixing the cable to be fixed to a plate-like structure 130 connected to the cable fixing device 100. Furthermore, the cable fixing device 100 provided in this disclosure also includes a second cantilever 120, which includes a third cantilever portion 122 for contacting the cable (not shown) to be fixed, and a fourth cantilever portion 124 for fixing the cable to be fixed to the plate-like structure 130, wherein the fourth cantilever portion 124 is connected to the second cantilever portion 114. Figure 2As can be seen, the second cantilever portion 114 and the fourth cantilever portion 124 are connected through their lower ends. The first cantilever portion 112 and the third cantilever portion 122 cooperate to fix the cable to be fixed, and the first cantilever portion 112 and the third cantilever portion 122 are connected only through the second cantilever portion 114 and the fourth cantilever portion 124.

[0053] In addition, from Figure 1 As can be seen from the examples, in one embodiment of this disclosure, a first recess 113 is provided on the outer side of the first cantilever 110 at the connection between the first cantilever portion 112 and the second cantilever portion 114, and a second recess 123 is provided on the outer side of the second cantilever 120 at the connection between the third cantilever portion 122 and the fourth cantilever portion 124. This allows the first recess 113 and the second recess 123 to engage with the corresponding plate-like structure (e.g., when the cable is not inserted between the first cantilever 110 and the second cantilever 120). Figure 2 and Figure 3 Within the plate-like structure 130). When the cable (e.g.) Figure 3 When a cable 140 with a circular cross-section is inserted between the first cantilever 110 and the second cantilever 120, the cable 140 will make the first recess 113 and the second recess 123 more securely joined to the plate structure 130.

[0054] In one embodiment, the first recess 113 and the second recess 123 are configured to secure the cable fastener 100 to an opening in the plate-like structure 130. The opening may be a through slot along the thickness direction of the plate-like structure. In one embodiment, the opening is rectangular. When installing the cable fastener 100, the first cantilever 110 and the second cantilever 120 are pushed towards each other, reducing the gap between them to facilitate a smoother insertion of the cable fastener 100 into the opening of the plate-like structure 130. The shape and size of the opening match the shape and size of the cable fastener 100 to achieve a mechanical engagement, thereby ensuring reliable installation. After the cable securing device 100 is inserted into the opening of the plate-like structure 130, the first recess 113 and the second recess 123 contact the inner wall of the opening, the second cantilever portion 114 and the fourth cantilever portion 124 extend outward from one side (e.g., the bottom) of the plate-like structure 130 along its thickness direction, and the first cantilever portion 112 and the third cantilever portion 122 extend outward from the other side (e.g., the top) of the plate-like structure 130 along its thickness direction. The cable securing device 100 can be used in mobile communication systems and devices. For example, the cable securing device 100 can be used in antenna equipment to secure cables to a reflector.

[0055] exist Figure 1 , Figure 2 and Figure 3 In the illustrated embodiment, the first cantilever portion 112 and / or the third cantilever portion 122 have arc-shaped inner surfaces. Optionally, in one embodiment of this disclosure, the first cantilever portion 112 and the third cantilever portion 122 are configured to clamp a cable to be secured (e.g., Figure 3 The cable shown is 140.

[0056] Figure 3 A schematic diagram is shown of a cable securing device 100 according to an embodiment of the present disclosure, after the cable is secured to a plate-like structure 130. From Figure 3 As can be seen from this, the cable fixing device 100 of this disclosure includes a first cantilever 110, which includes a first cantilever portion 112 for contacting the cable 140 to be fixed and a second cantilever portion 114 for fixing the cable to be fixed to a plate-like structure 130 connected to the cable fixing device 100. Furthermore, the cable fixing device 100 provided in this disclosure also includes a second cantilever 120, which includes a third cantilever portion 122 for contacting the cable 140 to be fixed and a fourth cantilever portion 124 for fixing the cable to be fixed to the plate-like structure 130, wherein the fourth cantilever portion 124 is connected to the second cantilever portion 114. Figure 3 As can be seen, the second cantilever portion 114 and the fourth cantilever portion 124 are connected through their lower ends. The first cantilever portion 112 and the third cantilever portion 122 cooperate to fix the cable to be fixed, and the first cantilever portion 112 and the third cantilever portion 122 are connected only through the second cantilever portion 114 and the fourth cantilever portion 124.

[0057] During operation, the operator can apply pressure to the first cantilever 110 and the second cantilever 120 of the cable fixing device 100 in a direction that brings them closer together, thereby reducing the gap between the first cantilever 110 and the second cantilever 120, and thus making it easier to install the cable fixing device 100 into the opening of the plate structure 130. The shape and size of the opening are matched with the shape and size of the cable fixing device 100 to form a mechanical snap-fit, thereby achieving a secure installation effect. Then, the operator can press the cable 140 between the first cantilever portion 112 and the third cantilever portion 122 of the cable fixing device 100.

[0058] After the cable 140 is pressed into the cable fixing device 100 between the first cantilever portion 112 and the third cantilever portion 122, as Figure 3 As shown, the first cantilever portion 112 and the third cantilever portion 122 will follow... Figure 3 The force F shown NA pressing force is applied to the cable 140 in the direction shown in the figure to securely fix the cable 140 between the first cantilever portion 112 and the third cantilever portion 122. Correspondingly, as a reaction force, the cable 140 will also move along the direction shown in the figure with respect to F. N In the opposite direction, a reaction force is applied to the first cantilever portion 112 and the third cantilever portion 122. That is, after the cable fixing device 100 is installed, the expansion force of the cable 140 can further make the fixation between the cable fixing device 100 and the plate structure 130 more secure.

[0059] To facilitate the easy pressing of the cable 140 into the space between the first cantilever portion 112 and the third cantilever portion 122, the ends of the first cantilever portion 112 and the third cantilever portion 122 have arc-shaped guide surfaces. The opening of the arc-shaped guide surface at these ends is slightly larger, thereby facilitating the pressing of the cable between the first cantilever portion 112 and the third cantilever portion 122.

[0060] In one embodiment of this disclosure, the distance between the distal end of the first cantilever portion 112 away from the second cantilever portion 114 and the distal end of the third cantilever portion 122 away from the fourth cantilever portion 124 is less than the maximum distance between the first cantilever portion 112 and the third cantilever portion 122. This makes it less likely for the cable 140 inserted between the first cantilever 110 and the second cantilever 120 to fall off. In other words, the opening of the cable fixing device 100 is smaller than the space for fixing the cable 140.

[0061] In one embodiment, to facilitate the securing of the cable fastener 100 to the plate structure 130 without the cable 140 being inserted, mechanical tension is provided at the bottom of the connection between the second cantilever portion 114 and the fourth cantilever portion 124 of the cable fastener 100 to maintain a stable shape. In this way, the cable fastener 100 without the cable 140 inserted can be smoothly pushed into the opening of the plate structure 130, while the mechanical tension keeps the cable fastener 100 without the cable 140 inserted within the opening of the plate structure 130.

[0062] Furthermore, during the process of inserting the cable 140 into the cable fixing device 100, the first cantilever 110 is pushed away from the second cantilever 120, and the second cantilever 120 is pushed away from the first cantilever 110, thereby causing the first recess 113 and the second recess 123 to be pushed away from each other. In this way, the cable 140 will make the connection between the first recess 113 and the second recess 123 and the plate structure 130 more secure. Figure 3 As can be seen, after the cable 140 is pressed into the space between the first cantilever portion 112 and the third cantilever portion 122 of the cable fixing device 100, the cable 140 will move along... Figure 3The S-direction in the middle applies a thrust to the cable fixing device 100, making it less likely for the cable fixing device 100 to fall off from the plate structure 130, thus making the connection between them more secure.

[0063] In addition, from Figure 1 , Figure 2 ,and Figure 3 As can be seen from the illustrated embodiments, the first cantilever 110 and the second cantilever 120 have mutually symmetrical structures. In one embodiment of this disclosure, the distance between the inner sides of the first cantilever 110 and the second cantilever 120 gradually increases longitudinally from the opening into the cable fixing device 100. In one embodiment of this disclosure, the distance between the inner sides of the first cantilever 110 and the second cantilever 120 first decreases and then increases longitudinally from the opening into the cable fixing device 100. In one embodiment of this disclosure, the distance between the inner sides of the first cantilever 110 and the second cantilever 120 first decreases, then increases, and then decreases again longitudinally from the opening into the cable fixing device 100.

[0064] In one embodiment of this disclosure, the cable securing device 100 is configured to secure the cable 140 to the plate-like structure 130. Those skilled in the art will understand that the plate-like structure 130 can be a reflector for an antenna or a circuit board for other devices.

[0065] In addition, this disclosure also provides an antenna, which includes a reflector and the aforementioned cable fixing device 100.

[0066] Figure 4 A perspective view of a cable fixing device 100 according to one embodiment of the present disclosure is shown. Figure 4 As can be seen from this, the cable fixing device 100 of this disclosure includes a first cantilever 110, which includes a first cantilever portion 112 for contacting the cable (not shown) to be fixed, and a second cantilever portion 114 for fixing the cable to be fixed to a plate-like structure 130 connected to the cable fixing device 100. Furthermore, the cable fixing device 100 of this disclosure also includes a second cantilever 120, which includes a third cantilever portion 122 for contacting the cable (not shown) to be fixed, and a fourth cantilever portion 124 for fixing the cable to be fixed to the plate-like structure 130, wherein the fourth cantilever portion 124 is connected to the second cantilever portion 114. Figure 4As can be seen, the second cantilever portion 114 and the fourth cantilever portion 124 are connected through their lower ends. The first cantilever portion 112 and the third cantilever portion 122 cooperate to fix the cable to be fixed, and the first cantilever portion 112 and the third cantilever portion 122 are connected only through the second cantilever portion 114 and the fourth cantilever portion 124.

[0067] The cable fixing device disclosed herein effectively saves installation space, breaking through the installation space limitations of ordinary cable clamps. Furthermore, the cable fixing device improves the cable clamp installation process, making installation simple and convenient, and increasing efficiency. Moreover, the cable fixing device of this disclosure strengthens the fixing of the cable clamp body while securing the cable, using the reaction force of the cable to make the overall fit more secure and reliable. In addition, the cable fixing device of this disclosure has a high fault tolerance rate, reducing the impact of material shrinkage and dimensional deviations.

[0068] According to certain embodiments, Figure 5A , Figure 5B A cable securing device 500 relative to a plate-like structure 130 is depicted exemplarily. The cable securing device 500 includes an upper body 540, a lower body 550, and a middle body 560 located between the upper body 540 and the lower body 550 along an engagement direction E. Although the engagement direction E is depicted as a downward-moving arrow as shown, the engagement direction E does not necessarily have to be a downward direction; it can also represent an upward direction from the perspective of the cable securing device 500. The engagement direction E may represent the direction in which the cable securing device 500 moves toward and engages with the plate-like structure 130, or it may represent the direction in which the plate-like structure 130 moves toward and engages with the cable securing device 500. The upper body 540 includes a first cantilever portion 512 and a third cantilever portion 522 to receive and clamp a cable, such as cable 140. The lower body 550 includes a second cantilever portion 514 and a fourth cantilever portion 524 connected to each other via a cantilever joint 530. The intermediate body 560 includes a first recess 513 and a second recess 523 that contact the plate-like structure 130.

[0069] Figure 5B yes Figure 5A A cross-sectional view along line 5B-5B, further considering... Figure 5B The upper body 540 is used to clamp the cable 140. The lower body 550 passes through the opening 570 of the plate-like structure 130 along the engagement direction E, sequentially passing through the front 534 and the back 536 of the plate-like structure 130. The middle body contacts the side wall 538 of the opening 570 of the plate-like structure 130, wherein the height H1 of the side wall 538 of the opening 570 of the plate-like structure 130 is less than the height H2 of the middle body 560 along the engagement direction E. See also Figure 5B and Figure 9BH2 is the distance from the bottom of ribs 742 and 744 to the lower end of body 560.

[0070] In some embodiments, the upper body 540, lower body 550, and middle body 560 are integrally formed. This can be achieved by injection molding or 3D printing of a single or composite material. Non-limiting examples of single or composite materials include resins, polymers, composite materials, or any suitable combination thereof.

[0071] In some embodiments, the upper body 540 differs from the middle body 560 in material or composition, the upper body 540 differs from the lower body 550 in material or composition, or the middle body 560 differs from the lower body 550 in material or composition. For example, to impart greater elasticity or scalability to the upper body 540, it may be formed of a resin or polymer that is more flexible than the material forming the middle body 560. For example, to impart greater rigidity to the middle body 560 to better withstand the reaction forces exerted by the sidewalls 538 of the plate-like structure 130, the middle body 560 may be formed of a resin or polymer that is less flexible than the material forming the lower body 550 or the upper body 540. When formed of different materials, the upper body 540, the middle body 560, and the lower body 550 can be attached to each other by any suitable adhesive, such as a polymeric adhesive.

[0072] In some embodiments, and as Figure 6 As shown, the upper body 540 is provided with a channel 620 extending along the engagement direction E, for the cable 140 to pass through along the engagement direction E. The channel 620 is configured with a neck width W1, chest width W2, and waist width W3 along the engagement direction E, and in a first position, for example... Figure 6 The displayed position is such that the chest width is greater than the neck width W1 or the waist width W3. At this time or in this position, the cable fixing device 500 is separated from the cable 140, or the cable 140 has not yet come into contact with the cable fixing device 500.

[0073] The neck width Wl can be defined by a first neck 642 and a second neck 644 of the upper body 540 projecting toward each other in a planar direction P. The planar direction P is the direction in which the front face 534 and / or the back face 536 of the plate structure 130 extend. Viewed from inside the channel 620, the first neck 642 and the second neck 644 define a convex portion of the channel 620.

[0074] The chest width W2 can be defined by the first chest 652 and the second chest 654 of the upper body 540, which protrude from each other along the planar direction P. Viewed from inside the channel, the first chest 652 and the second chest 654 define a concave portion of the channel 620.

[0075] The waist width W3 can be set by the first waist 662 and the second waist 664 of the upper body 540 protruding towards each other in the planar direction P. When viewed from inside the passage, the first waist 662 and the second waist 664 define what appears to be a concave portion of the passage 620.

[0076] According to certain embodiments, Figure 6 The first position is schematically shown, in which the cable fixing device 500 and the cable 140 are separate from each other, while Figure 7 The second position is schematically shown, in which cable 140 begins to contact cable securing device 500 and travels downward in the engagement direction E to eventually be received within channel 620. In the second position, the neck width W1 is widened to allow cable 140 to travel in the engagement direction E. The widening of neck width W1 is a result of cable 140 being pressed down in the engagement direction E, and the downward pressure can be applied by the operator's hand force or any suitable mechanical tool. As cable 140 travels downward through channel 620 in the engagement direction E, one or more ribs 742 and 744 of upper body 540 press downward in the engagement direction E onto the front surface 534 of plate structure 130, while lower body 550 rides in a direction opposite to the engagement direction to reduce the height difference ΔH between H1 and H2. The riding of lower body 550 is a result of one or both of ribs 742 and 744 pressing downward onto plate structure 130 via, for example, a lever mechanism.

[0077] Let's look again. Figure 6 The height difference ΔH is located in region AA, closer to the back side 536 than the front side 534 of the plate-like structure. As the cable 140 continues to travel downwards in the engagement direction E, the value of the height difference ΔH decreases from ΔH1 to ΔH2. The decreasing or disappearing height difference ΔH is shown in the diagram. Figure 7 In region BB. For example... Figure 8 As shown, cable 140 continues to travel along the engagement direction E and stops in channel 620. As cable 140 travels downward along the engagement direction E, the value of the height difference ΔH can continuously decrease from ΔH2 to ΔH3.

[0078] In some embodiments, and as Figure 12 As shown, the lower part 550 of the cable fixing device 500 is positioned above the front side 534 of the plate-like structure 130, as relative to... Figure 6 In the comparison, the lower part 550 of the cable fixing device 500 is shown as being located below the front 534 of the plate structure 130.

[0079] The height difference ΔH1 can be any suitable value. Non-limiting examples of the range of values ​​for the height difference ΔH1 are 1.0 mm to 20.0 mm, 2.0 mm to 15.0 mm, and 5.0 mm to 10.0 mm. Preferably, the value of the height difference ΔH1 is associated with the thickness H1 of the plate structure 130, for example: 0 to H1, 0.25H1 to 0.75H1, 0.25H1 to 0.5H1.

[0080] In some embodiments, and as Figure 5B , Figure 6 , Figure 7 and Figure 8 As schematically shown, the height difference ΔH is positioned closer to the rear face 536 relative to the front face 534. In some other embodiments, the height difference ΔH may also be positioned (not shown) closer to the front face 534 relative to the rear face 536.

[0081] Let's look again. Figure 7 As the cable 140 travels downward, the first neck 642 and the second neck 644 open outward, the ribs 742 and / or ribs 744 press downward on the front 534 of the plate structure 130, and the lower body 550 rides upward. The stretching regions 752 and 754 begin to form or appear in the waist 662 and 664 as a compensation mechanism to reduce or eliminate the height difference ΔH.

[0082] In the first position, the cable fixing device is separated from the cable; in the second position, the cable fixing device contacts the cable, and a tension area of ​​the middle body sits on the front of the plate structure, positioned between the cable and the front of the plate structure.

[0083] The stretching areas 752 and 754 can each be indicated by their height R along the engagement direction E. (See reference) Figure 6 The waist width W3 can define the distance between points G1 and G2 of the upper body 540. In comparison, Figure 7 The diagram schematically depicts points G1 and G2 moving upwards away from the front face 534. Consequently, material from the intermediate body 560 is displaced to accommodate the displacement of points G1 and G2, and the displaced material forms at least a portion of the stretching regions 752, 754. The height R corresponds to the amount of upward movement of points G1 and G2 away from the front face 534. Furthermore, the amount of material displacement gradually decreases along the planar direction P in the outward and away-from-channel 620 directions. For example, as... Figure 7 As shown, the stretching region 752 is defined by points G1 and G1' of the upper body 540 and points F1 and F2 of the middle body 560. The distance R between points G1 and F1 is R1, and the distance R measured at points G1' and F2 is R2, where R1 is greater than R2.

[0084] The distances R1 and R2 can be any suitable values. Non-limiting examples of the range for distance R1 are 0.5 mm to 10.0 mm, 1.0 mm to 5.0 mm, and 1.5 mm to 3.0 mm. Preferably, the value of distance R1 is associated with the thickness H1 of the plate structure 130, for example: 0 to H1, 0.25H1 to 0.75H1, and 0.25H1 to 0.5H1. Non-limiting examples of the range for distance R2 are 0.05 mm to 1.0 mm, 0.1 mm to 0.5 mm, and 0.15 mm to 0.3 mm.

[0085] Figure 10 A perspective view of ribs 742 and 744 is schematically depicted, where ribs 742 and 744 are shown extending along the length direction L. The length direction L may be the direction of extension of cable 140.

[0086] The downward pressure of ribs 742 and 744 on the plate structure 130 and the upward lifting of the lower body 550 together further ensure the clamping of the cable 140 and reduce unwanted swaying along the engagement direction E.

[0087] Let's look again. Figure 6 Furthermore, in some embodiments, the lower body 550 is provided with a cavity 690. The cavity 690 allows the lower body 550 to move inward or otherwise temporarily deform as it travels along the engagement direction E through the opening 570 of the plate structure 130.

[0088] In some embodiments, the tail width W4 of the cavity 690 may be smaller than the chest width W2 of the upper body 540. In some embodiments, the tail width W4 of the cavity 690 may be smaller than the neck width W1 or waist width W3 of the upper body 540.

[0089] In some embodiments, cavity 690 is part of a channel formed by upper body 540, middle body 560, and lower body 550. Cavity 690 may be Figure 6 This is a portion of channel 620 shown. Let's look at it again. Figure 5B In the diagram, channel 590 is schematically shown as a cavity that starts from the upper body 540, passes through the middle body 560, and continues into the lower body 550.

[0090] In some embodiments, and further as Figure 9A As shown, the cross-section 910 of the mid-body 560 taken along the plane direction P is quadrilateral, including the front side 912, the rear side 914, the left side 916 and the right side 918, wherein the left side 916 and / or the right side 918 both extend along the length direction L of the cable 140.

[0091] Although Figure 9AThe cross section 910 is exemplarily shown as a quadrilateral, but it may have any other suitable shape and any suitable number of sides or edges. In some embodiments, the cross section 910 may be a shape with a different number of sides than a quadrilateral, such as a triangular or pentagonal shape, may be a shape with curved sides, such as an ellipse or an elongated ellipse, and may be a shape that includes one or more straight sides and one or more curved sides.

[0092] Let's look again. Figure 9A The cross-section 920 of the lower body 550 along the planar direction P is larger than the cross-section 910 of the middle body 560 to prevent the plate structure 130 from detaching from the lower body 550. The cross-section 930 of the upper body 540 along the planar direction P is also larger than the cross-section 910 of the middle body 560 to prevent the plate structure 130 from detaching through the upper body 540. The cross-sections 920, 910, and 930 together form a recessed area in the middle body 560 relative to the upper body 540 and the lower body 550, further enhancing the engagement of the plate structure 130 with the cable fixing device 500.

[0093] Furthermore, given Figure 9B , Figure 9A The cross-section 910 shown in the figure has a dimension of 910D. Figure 9A The displayed cross-section 920 has a dimension 920D. Figure 9A The cross-section 930 shown has a dimension 930D.

[0094] Despite Figure 9A The diagram schematically shows a circular cross-section. The cross-section of cable 140 can be any suitable shape, such as an elliptical cross-section, or a shape with one or more straight sides and one or more curved sides.

[0095] This disclosure also provides a cable securing assembly. This cable securing assembly includes a cable securing device, such as the cable securing device 500 in the foregoing embodiments, and a plate-like structure, such as the plate-like structure 130 in the foregoing embodiments. In this cable securing assembly, the cable securing device and the plate-like structure can be separated from each other for easy packaging and transportation, or they can be pre-assembled as shown in the previous embodiment. Figure 5A or Figure 5B The structure shown is designed to improve user-friendliness. In the pre-assembled form, the plate structure 130 can be provided with two or more openings, and the number, location, and / or size of the openings can be customized to accommodate cable fixing devices of different sizes or materials to suit specific implementation details.

[0096] In some embodiments, and further considering Figure 11The plate-like structure 130 may have two or more openings, which may have the same opening size or different opening sizes. In certain specific embodiments, such as Figure 11 As shown, one or more openings with larger opening sizes are defined to accommodate one or more cable securing devices for securing one or more cables with correspondingly larger cable sizes, and one or more openings with smaller opening sizes are defined to accommodate one or more cable securing devices for securing one or more cables with correspondingly smaller cable sizes. In some other specific embodiments, one or more openings with larger opening sizes can be used to combine with one or more openings with smaller opening sizes in any way to accommodate cables with variable cable sizes along their length.

[0097] For example Figure 11 The openings in the illustrative plate-like structure can be customized in position and size to meet the requirements of custom orders, and can be supplied in conjunction with cable fasteners of matching dimensions. When supplied in an assembled form, the plate-like structure and cable fasteners can be like... Figure 5A or Figure 5B The cable securing assembly is illustrated in the diagram, or it can be packaged separately. When supplied in a connected form, the cable securing assembly can be immediately installed to secure the cable upon removal from the package, thus contributing to greater efficiency and shorter installation time.

[0098] Let's look again. Figure 11 As shown, the plate-like structure 1130 may include a relatively large opening 1132, a relatively small opening 1134, an opening 1136 having a shape with one or more curved edges and / or one or more straight edges, and / or an opening 1138 having a shape with three sides.

[0099] This disclosure also provides a cable securing assembly to include a cable, such as cable 140, and a cable securing device, such as cable securing device 500. In this type of assembly, one or more cables may be configured to have the same or variable dimensions, and the cable securing devices may also be configured to have the same or variable dimensions. One or more cables and one or more cable securing devices may be provided separately from each other, and optionally, different size combinations may be indicated by color coding. In some embodiments, one or more cables and one or more cable securing devices may be designed such that, after the cable is pre-attached to its corresponding cable securing device, undesirable situations such as the engaging unit entering an opening in the plate-like structure by itself can be prevented.
