Description

Technical Field

[0001] This application relates to cable protection devices. Background Technology

[0002] Common cable clamping structures typically involve sleeves of rubber components over the cable, followed by sealing and securing the rubber components to the plate through which the cable passes using adhesive. However, adhesive sealing makes cable replacement and maintenance inconvenient. Furthermore, existing cable protection devices often use sockets to seal the cable through the through-hole. These sockets require significant force to install and remove, and precise installation angles increase installation difficulty. They also present challenges in installation and maintenance due to poor sealing performance. Over time, these sockets are prone to loosening due to vibration or external forces, gradually reducing their sealing performance and allowing dust and moisture to enter the device.

[0045] The following specific embodiments will further illustrate the present application in conjunction with the above-mentioned drawings. Specific embodiments

[0046] The technical solutions in the embodiments of the present application will be described clearly and completely in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are part of the embodiments of the present application, rather than all the embodiments of the present application.

[0047] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this application belongs. The terminology used in the description herein is for describing particular embodiments only and is not intended to be limiting of the application.

[0048] In order to further clarify the technical means and effects taken by the present application to achieve the predetermined purpose, the following will be described in detail in combination with the drawings and preferred embodiments.

[0049] Please refer to Figure 1 and Figure 2 The cable protection device 100 provided by the embodiments of the present application comprises a fixing member 10 and a clamping member 30, wherein the fixing member 10 is used to be sleeved on the cable 230, and the clamping member 30 is used to be clamped on the fixing member 10.

[0050] The fixing member 10 comprises a body portion 14, and a through hole 12 is formed on the body portion 14, which is used for the cable 230 to pass through so as to make the fixing member 10 be sleeved on the cable 230. The outer periphery of the fixing member 10 is provided with at least one limiting portion 11 used to cooperate with the plate, and at least one clamping portion 13 used for mounting connection, and the clamping portion 13 and the limiting portion 11 are arranged in the axial direction of the body portion 14. The clamping member 30 is detachably connected with the clamping portion 13, which is used to cooperate with the limiting portion 11 to limit the fixing member 10, so as to fix the cable 230 on the plate.

[0051] Specifically, please refer to Figure 2 and Figure 3 In the embodiment, the body portion 14 is approximately a columnar structure extending along a center axis, and the through hole 12 is formed along the position of the center axis, so that when the fixing member 10 is sleeved on the cable 230, the fixing member 10 can uniformly wrap the cable 230, thereby avoiding the abrasion of the fixing member 10 due to the uneven thickness; preferably, the body portion 14 can also be a square structure or other shapes, which is determined according to the profile shape of the hole required to cooperate on the plate.

[0052] The hole diameter of the through hole 12 is set according to the size of the cable 230, so that the cable 230 can be fully wrapped, avoiding the cable 230 slipping in the through hole 12, or the fixing part 10 cannot be sleeved on the cable 230. The cross-sectional shape of the through hole 12 is also set according to the cross-sectional shape of the cable 230, that is, the through hole 12 is set to match the external contour of the cable 230, for example, when the cross-sectional shape of the cable 230 is circular, the cross-sectional shape of the through hole 12 is also set to circular, so as to fully fit the cable 230 to achieve the fixation of the cable 230. In other embodiments, the through hole 12 can also be set to be larger than the size of the cable 230 according to actual needs, so as to facilitate the movement of the cable 230 in the radial direction of the fixing part 10, which is not limited in the present application.

[0053] The limiting part 11 is a protruding structure arranged on the radial surface of the body part 14. In some embodiments, the limiting part 11 is an annular structure surrounding the body part 14, and the limiting part 11 is integrally formed with the body part 14 and used to limit the position of the fixing part 10 in the axial direction. Specifically, when the body part 14 passes through the through hole on the plate in the axial direction, the limiting part 11 can abut against the plate to limit the movement of the fixing part 10 in the axial direction. In other embodiments, the limiting part 11 can also be a plurality of protruding structures arranged at intervals, and the limiting part 11 can be fixed on the body part 14 by a clamping structure or by adhesive, which is not limited in the present application.

[0054] In the present embodiment, the limiting part 11 is located at one end of the body part 14, and in other embodiments, the limiting part 11 can also be arranged at other positions on the body part 14, which is not limited in the present application.

[0055] The clamping part 13 is a recessed structure arranged on the radial surface of the body part 14. In some embodiments, the clamping part 13 is an annular structure arranged along the circumference of the body part 14, and the depth of each position of the clamping part 13 is the same, that is, the cross-sectional shape of the corresponding part of the body part 14 is the same as that of other positions of the body part 14. The clamping part 13 is used to clamp the clamping part 30, thereby forming a limiting structure for limiting the movement of the fixing part 10 in the axial direction. The clamping part 30 clamped on the clamping part 13 cooperates with the limiting part 11, thereby fixing the position of the fixing part 10 in the axial direction.

[0056] In other embodiments, the clamping portion 13 can also be an arc-shaped structure that does not completely surround the body portion 14, and the depth of the clamping portion 13 at different positions can also be different. For example, the bottom wall of the clamping portion 13 can be a flat surface, that is, the clamping portion 13 is opened in a single direction, or the clamping portion 13 can be opened in multiple directions perpendicular to the radial direction of the body portion 14, so that the corresponding part of the body portion 14 formed by the clamping portion 13 has a polygonal cross section. Alternatively, the clamping portion 13 can be opened in multiple directions on the same surface perpendicular to the axial direction of the fixing member 10, and the present application does not limit this, as long as the clamping portion 13 can be clamped with the clamping member 30, it is within the scope of the present application.

[0057] The distance between the limiting portion 11 and the clamping portion 13 is set according to the actual use. Specifically, the cable protection device 100 is used to clamp the cable 230 on the plate, and the limiting portion 11 and the clamping member 30 clamped on the clamping portion 13 respectively limit the movement of the fixing member 10 in the axial direction from both sides of the plate, so the distance between the limiting portion 11 and the clamping portion 13 needs to be determined according to the thickness of the plate, so as to ensure that the fixing member 10 and the clamping member 30 can be stably fixed on the plate.

[0058] In some embodiments, the end of the body portion 14 away from the limiting portion 11 is chamfered, so that the end of the body portion 14 forms a certain slope, so as to facilitate the fixing member 10 to pass through the through hole on the plate.

[0059] The fixing member 10 is made of a flexible and environmentally resistant material, such as rubber or silicone, so that it can adapt to cables 230 of different sizes or shapes, and also has good anti-aging and corrosion resistance, which is beneficial to improve the service life.

[0060] Optionally, the cable protection device 100 further comprises a sealing piece 50, which is sleeved on the fixing piece 10 and located between the limiting part 11 and the plate, and used to abut against the plate and the limiting part 11 respectively when the cable protection device 100 is clamped on the plate, so as to form a sealed isolation on both sides of the plate. Specifically, the sealing piece 50 is made of elastic material and will deform when subjected to pressure, so as to fill the gap between the limiting part 11 and the plate and achieve the sealing effect. The sealing piece 50 can be integrally formed with the fixing piece 10 or can be a detachable structure. The size of the sealing piece 50 can be set according to actual needs, for example, the radius of the sealing piece 50 needs to be set according to the size of the through hole on the plate, so as to ensure that the sealing can be achieved, and the thickness of the sealing piece 50 can be set according to the thickness of the plate, so as to limit the fixing piece 10 in the axial direction together with the limiting part 11; preferably, the present application can also provide sealing pieces 50 of various specifications, and users can select appropriate sealing pieces 50 according to the thickness of the plate to be sleeved on the fixing piece 10, so that they can adapt to plates of different thicknesses to achieve the installation and protection of cables. Preferably, the sealing piece 50 is made of shape memory material and can deform and fit the plate under the action of high temperature or pressure, and recover to the original shape after the pressure is removed, which can be reused, and the present application does not limit this.

[0061] Please refer to Figure 4 and Figure 5 The clamping piece 30 comprises a base 31 and at least two support parts 33 extending away from the base 31, and the support parts 33 are configured to be clamped in the clamping part 13 of the fixing piece 10. Specifically, in the present embodiment, the two support parts 33 are located at both ends of the base 31 and extend away from the base 31 at a certain angle, and the two support parts 33 and the base 31 form a certain included angle and protrude outward from both ends of the base 31 to form an arc or arch structure; preferably, the extension direction of the support part 33 can be designed to form a fixed included angle with the base 31 according to actual needs, and the included angle can be set according to actual conditions, which can be 15-75 degrees, preferably 30 degrees or 45 degrees, and the shape of the two support parts 33 can be linear or slightly curved to adapt to different clamping environments. The two support parts 33 are used to clamp into the clamping part 13 from opposite directions, so as to limit the position of the clamping piece 30.

[0062] In some embodiments, the base 31 is formed with a first inclined portion 35 away from the side of the support portion 33, the first inclined portion 35 extending from the position of the base 31 towards the direction away from the support portion 33 and being arranged inclinedly relative to the base 31. The first inclined portion 35 is used to abut against the fixing member 10 in the direction away from the limiting portion 11 when the clamping member 30 is clamped on the clamping portion 13. Specifically, the first inclined portion 35 is a plate-shaped structure arranged bently relative to the base 31, the first inclined portion 35 is used to guide the clamping member 30 to slide into the clamping portion 13 when the clamping member 30 is inserted into the clamping portion 13, after the clamping member 30 is clamped on the fixing member 10, the first inclined portion 35 is arranged towards the direction away from the limiting portion 11 and exerts a force on the fixing member 10 in the direction away from the limiting portion 11 when subjected to pressure, thereby limiting the position of the fixing member 10 together with the limiting portion 11 when the fixing member 10 is arranged on the plate, the slope design of the first inclined portion 35 can effectively guide the clamping member 30 to slide smoothly into the clamping portion 13, reduce possible jamming or mismatching during insertion, ensure the close fit between the clamping member 30 and the clamping portion 13, through this structure, the fixing member 10 not only closely fits with the clamping member 30 when subjected to external pressure, but also remains stable when subjected to force by virtue of the design of the inclined portion, preventing loosening during work, thereby improving the service life and reliability of the device.

[0063] In some embodiments, the included angle a between the plane where the first inclined portion 35 is located and the plane where the base 31 is located is 15°-75°, preferably 15°-75°, which can provide smooth guidance without hindering the insertion of the clamping member 30. Thus, it ensures that the clamping member 30 is smoothly guided when inserted into the clamping portion 13, but does not hinder the movement of the clamping member 30. The thickness and length of the first inclined portion 35 in the direction perpendicular to the base 31 are configured to ensure that the clamping member 30 does not deform or break during use, thereby prolonging the service life of the clamping member 30.

[0064] The surface of the first inclined portion 35 is formed with anti-slip texture. Specifically, in the present embodiment, the first surface 351 of the first inclined portion 35 is formed with anti-slip texture, thereby increasing the friction when in contact with the fixing member 10, which is conducive to enhancing the clamping strength and anti-vibration performance of the clamping member 30 and the fixing member 10.

[0065] In some embodiments, each support portion 33 is formed with a second inclined portion 37 at an end thereof away from the base portion 31. The second inclined portion 37 extends from the end of the support portion 33 away from the base portion 31 and is arranged to be inclined with respect to the support portion 33. The second inclined portion 37 is used to abut against the fixing member 10 in a direction away from the limiting portion 11 when the clamping member 30 is clamped on the clamping portion 13. Specifically, the second inclined portion 37 is bent in the same direction as the first inclined portion 35, so as to jointly abut against the fixing member 10. After the clamping member 30 is clamped on the fixing member 10, the second inclined portion 37 is arranged in a direction away from the limiting portion 11 and exerts a force on the fixing member 10 in a direction away from the limiting portion 11 when subjected to pressure, so as to jointly limit the position of the fixing member 10 with the limiting portion 11 when the fixing member 10 is arranged on the board. The second inclined portion 37 is also used to clamp the side wall of the clamping portion 13, so as to prevent the clamping member 30 from loosening or falling off.

[0066] In some embodiments, the included angle β between the plane in which the second inclined portion 37 is arranged and the plane in which the support portion 33 is arranged is 15°-75°, so as to ensure that the second inclined portion 37 can stably clamp the bottom of the clamping portion 13 after the clamping member 30 is clamped on the clamping portion 13. The size of the second inclined portion 37 is arranged to correspond to the depth and width of the clamping portion 13, so as to ensure that the second inclined portion 37 can be closely matched with the fixing member 10 to increase the locking strength. The thickness of the second inclined portion 37 is configured to ensure that the clamping member 30 will not be deformed or damaged when in use, so as to prolong the service life of the clamping member 30.

[0067] The surface of the second inclined portion 37 is formed with anti-slip textures. Specifically, in the present embodiment, the second surface 371 of the second inclined portion 37 is bent inward and is formed with anti-slip textures, so as to increase the friction when in contact with the fixing member 10, and to facilitate the increase of the clamping strength and the anti-vibration performance of the clamping member 30 and the fixing member 10.

[0068] In some embodiments, the distance between the two support portions 33 is greater than the diameter of the fixing member 10 at the position of the clamping portion 13, so that the clamping member 30 can be inserted into the clamping portion 13.

[0069] In some embodiments, the material of the clamping member 30 can be metal materials such as stainless steel or high-strength spring steel, so that the clamping member 30 has good elasticity and strength, so as to ensure the stability of the included angle α between the first inclined portion 35 and the base portion 31, and the stability of the included angle β between the second inclined portion 37 and the support portion 33, and to further ensure the locking force of the clamping member 30.

[0070] Please refer to Figure 6 and Figure 7 , and the structure of the cable protection device 100 will be further described below in combination with actual use scenarios.

[0071] The cable protection device 100 is used for clamping the cable 230 on the plate 210, wherein the plate 210 is provided with a through hole 220 for the cable 230 to pass through, and the through hole 220 penetrates the first side wall 211 and the second side wall 213 of the plate 210. The fixing member 10 is sleeved on the cable 230 and passes through the through hole 220 together with the cable 230, so that the limiting portion 11 of the fixing member 10 is located on the side of the plate 210 facing the first side wall 211, and the clamping portion 13 passes through the through hole 220 and is located on the side of the plate 210 facing the second side wall 213. The clamping member 30 is clamped on the clamping portion 13, so as to limit the position of the fixing member 10 on both sides of the plate 210 respectively.

[0072] The sealing member 50 is arranged between the limiting portion 11 and the first side wall 211, so as to seal the two sides of the plate 210. Since the sealing member 50 and the fixing member 10 are both made of elastic material and realize the sealing function through the elastic characteristics, when the limiting portion 11 abuts against the first side wall 211, the fixing member 10 will be subjected to a rebound force in the direction away from the first side wall 211, so as to drive the base 31 and the supporting portion 33 of the clamping member 30 to abut against the second side wall 213. The rebound force is transmitted to the clamping member 30 through the fixing member 10, so that the base 31 and the supporting portion 33 of the clamping member 30 are tightly abutted against the second side wall 213, thereby realizing the stable connection between the fixing member 10 and the plate 210. The first inclined portion 35 and the second inclined portion 37 of the clamping member 30 will further exert an elastic force on the fixing member 10 in the direction away from the second side wall 213, so as to clampingly fix the fixing member 10 and the plate 210. During the clamping process, the cooperation between the clamping member 30 and the fixing member 10 will form a stable supporting point on the side of the second side wall 213, so as to limit the reverse movement of the fixing member 10. The first inclined portion 35 and the second inclined portion 37 of the clamping member 30 are elastically designed, so as to exert an elastic force on the fixing member 10 in the direction away from the second side wall 213, thereby further enhancing the fixing effect.

[0073] The cable protection device 100 provided by the embodiment of the application can abut against the plate from one side of the plate through the limiting portion 11, and can abut against the plate from the other side of the plate through the cooperation between the clamping member 30 and the clamping portion 13 of the fixing member 10, so as to clamp and fix the cable 230 on the plate. The cable protection device 100 is simple in structure and convenient to install and disassemble, and is beneficial to the replacement and maintenance of the cable.

[0074] Please refer to Figure 8In an embodiment, the cable protection device 100 can be applied to any product including a cable via structure. For example, the cable protection device 100 can be applied to an electronic device, the cable 230 is an electric cable or wire, and the plate 210 can be a housing of the electronic device, or an installation plate, a positioning plate, or a circuit board inside the electronic device. The cable protection device 100 can be applied to a mechanical structure, the cable 230 is a gas guide tube, a liquid guide tube, or a cable in the mechanical structure, and the plate 210 is a housing or an installation plate inside the mechanical structure. The specific application scenarios of the cable protection device 100 are not limited in the present application.

[0075] In some embodiments, one device can include a plurality of cables 230, each cable 230 corresponding to one cable protection device 100. The shapes and sizes of the plurality of cables 230 can be different, and the through holes 12 on the fixing member 10 in the cable protection device 100 are arranged according to the shapes and sizes of each cable 230.

[0076] Those skilled in the art should understand that the above embodiments are only used to illustrate the present application, and are not used as a limitation to the present application. Any appropriate changes and modifications made to the above embodiments within the spirit and principles of the present application fall within the scope of the present application.
