Description

Technical Field

[0001] The utility model belongs to the technical field of cable fixing, and in particular relates to a cable fixing device. Background Art

[0002] Cables (including optical cables and electrical cables) play a vital role in daily life and industrial production, serving as essential elements for controlling installations, connecting devices, and transmitting power. If cables are not effectively secured during use, they can become tangled, tangled with other objects, or bent, potentially causing damage. Therefore, securing devices are essential to effectively secure cables.

[0003] Existing cable fixing devices include a housing with a mounting cavity and a self-clinching stud. The cable is first welded to the self-clinching stud, which is then secured within the mounting cavity using a riveting machine. The machine applies external force to the self-clinching stud, deforming the cavity wall. This deformed portion of the cavity wall is then squeezed into the guide groove or back-off groove of the self-clinching stud, creating a mechanical locking effect. While this fixing method can effectively secure the cable, if the cable is skewed or improperly secured, the inner wall of the mounting cavity will deform, making it difficult to remove the self-clinching stud for adjustment, rendering the entire cable fixing device useless.

[0026] The disclosure below provides many different embodiments or examples for realizing different structures of the present invention. In order to simplify the disclosure of the present invention, the components and settings of specific examples are described below. Of course, they are merely examples and are not intended to limit the present invention. In addition, the present invention may repeat reference numbers and / or reference letters in different examples.

In addition, the present invention provides examples of various specific processes and materials, but a person of ordinary skill in the art will appreciate the application of other processes and / or the use of other materials.

[0027] Existing cable fixing devices include a housing with a mounting cavity and a self-clinching stud. The self-clinching stud is fixed in the mounting cavity by a self-clinching machine. The self-clinching machine applies external force to the self-clinching stud to deform the cavity wall around the mounting cavity. The deformed cavity wall is squeezed into the guide groove or back-off groove of the self-clinching sleeve stud, forming a mechanical locking effect. If the cable is skewed or not fixed properly, the mounting cavity will be deformed, making it difficult to remove the self-clinching stud for adjustment, resulting in the entire cable fixing device being scrapped. The present utility model provides a cable fixing device that aims to reduce the possibility of the housing mounting cavity being deformed and unable to be reused during cable installation.

[0028] See also Figures 1 to 3 The cable fixing device of the present invention includes a housing 100, a fixing member, and a fastener 300. The housing 100 has an installation cavity 110, and the installation cavity 110 has an opening 111. A through hole 112 communicating with the installation cavity 110 is opened on the side of the housing 100. The through hole 112 is used for the cable 500 to pass through. The fixing member is installed in the installation cavity 110. A through hole 212 is opened on the peripheral side of the fixing member for the cable 500 to pass through. The fixing member is fixedly connected to the cable 500 in the through hole 212. The fastener 300 includes a cover plate 310 and a screw 320 passing through the cover plate 310. At one end of the opening 111, the housing 100 has a screw hole 130 for the screw 320 to pass through. The upper end of the fixing member abuts against the cover plate 310, and the bottom of the fixing member abuts against the bottom of the installation cavity 110, so that the fixing member is clamped between the cover plate 310 and the housing 100.

[0029] In this way, since the cable 500 is fixed on the fixing part, the fixing part is locked in the installation cavity 110 by the fastener 300, so that the fixing part is compressed and fixed between the cover plate 310 and the shell 100. Since the fastener 300 is threadedly connected to the shell 100 by the screw 320, when the cable 500 is skewed or not fixed properly, etc., the fastener 300 is conveniently disassembled to adjust and reinstall the fixing part, so that the installation cavity 110 of the shell 100 is not easily deformed and cannot be reused, thereby improving the reuse rate and installation fault tolerance of the cable fixing device and reducing production costs.

[0030] Optionally, in one embodiment, the fixing member is configured as a cable fixing column 200. Above the cable fixing column 200, the cable fixing column 200 is provided with a casting hole 211 connected to the through hole 212. Solder is filled in the casting hole 211 for welding the cable 500 to the cable fixing column 200.

[0031] In this way, a pouring hole 211 connected to the through hole 212 is opened on the cable fixing column 200, and solder is filled in the pouring hole 211 to weld the cable 500 to the through hole 212 of the cable fixing column 200, thereby achieving the fixation of the cable 500 in the cable fixing column 200. The pouring hole 211 is opened above the cable fixing column 200 to facilitate the filling of solder in the pouring hole 211, so that the solder is not easy to escape or leak.

[0032] It is understandable that, in another embodiment, there are multiple ways to fix the cable 500 on the cable fixing column 200, which are not limited to soldering. The casting hole 211 can also be filled with glue such as epoxy resin glue or polyurethane glue to fix the cable 500 in the cable fixing column 200, as long as the cable 500 can be installed and fixed in the cable fixing column 200.

[0033] Optionally, in one embodiment, in the up and down directions of the cable fixing column 200, the cable fixing column 200 has a first column 210 and a second column 220, the outer diameter of the first column 210 is greater than the outer diameter of the second column 220, the through hole 212 and the casting hole 211 are both provided in the first column 210, the first column 210 abuts against the inner wall of the installation cavity 110, and the bottom of the second column 220 abuts against the bottom wall of the installation cavity 110.

[0034] In this way, the cable fixing column 200 has a first column 210 and a second column 220 in the upper and lower directions respectively. The outer peripheral side of the first column 210 abuts against the cavity wall of the installation cavity 110, thereby increasing the friction between the first column 210 and the cavity wall of the installation cavity 110, making it difficult for the cable fixing column 200 to move in the installation cavity 110, thereby improving the installation stability of the cable fixing column 200 in the installation cavity 110. The outer diameter of the second column 220 is smaller than the outer diameter of the first column 210, so that the second column 220 will not abut against the inner wall of the installation cavity 110. Therefore, the second column 220 can smoothly contact the bottom wall of the installation cavity 110, and will not hang above the bottom wall of the installation cavity 110, making the cable fixing column 200 easy to deviate, causing the cable 500 to be skewed, thereby improving the installation stability of the cable fixing column 200 in the installation cavity 110.

[0035] Optionally, in another embodiment, the outer diameters of the first column 210 and the second column 220 can be set in various ways, and the first column 210 and the second column 220 can also be set to the same outer diameter, as long as the cable fixing column 200 can be installed in the installation cavity 110.

[0036] Optionally, in one embodiment, the outer surface of the first column 210 is a smooth surface.

[0037] In this way, the outer surface of the first column 210 is set to a smooth surface to reduce the friction between the first column 210 and the wall of the installation cavity 110, so that when installation errors occur and disassembly and adjustment are required, the wall of the installation cavity 110 is not easily damaged by the friction between the first column 210, thereby reducing the wear on the wall of the installation cavity 110 and improving the reuse rate and installation fault tolerance of the shell 100.

[0038] Optionally, in one embodiment, the cable fixing device further includes a limit member 400, which includes a limit member body 410 and a protrusion 420 provided at the lower end of the limit member body 410. At one end of the casting hole 211, the first column 210 is provided with a card slot 213 connected to the casting hole 211, and the protrusion 420 is adapted to be buckled into the card slot 213. The limit member 400 is clamped between the cover plate 310 and the cable fixing column 200, and the peripheral side of the limit member body 410 abuts against the side wall of the installation cavity 110.

[0039] In this way, a limit member 400 is provided, and the protrusion 420 is adapted to be buckled into the card slot 213. The limit member 400 is clamped and fixed between the cable fixing column 200 and the cover plate 310 to limit the rotation of the cable fixing column 200 in the installation cavity 110, thereby reducing the possibility that the cable fixing column 200 rotates in the installation cavity 110 and causes the cable 500 to bend or even entangled with the housing 100, thereby improving the stability of the installation of the cable fixing column 200.

[0040] Optionally, in another embodiment, there may be multiple ways to limit the rotation of the cable fixing column 200 in the installation cavity 110. A sealing ring may also be installed in the gap between the cable fixing column 200 and the wall of the installation cavity 110 to limit the rotation of the cable fixing column 200 in the installation cavity 110.

[0041] Optionally, in one embodiment, the limit member 400 further includes limit columns 430 provided on both sides of the limit member body 410. At one end of the opening 111, the shell 100 is provided with a sink 120 connected to the installation cavity 110. The sink 120 is opened along the upper and lower directions of the shell 100. The installation cavity 110 is provided with a sink 120 on both opposite sides. A limit column 430 is adapted to be embedded in a sink 120, and the peripheral side wall of the limit column 430 abuts against the side wall of the sink 120.

[0042] In this way, limiting posts 430 are provided on both sides of the limiting member 400, and a recessed groove 120 adapted to be snapped with the limiting posts 430 is provided at the upper end of the shell 100. The limiting member 400 is installed at the upper end of the shell 100 to limit the rotation of the limiting member 400, further limit the rotation of the cable fixing post 200, improve the stability of the cable fixing post 200 in the installation cavity 110, and reduce the possibility that the cable fixing post 200 rotates in the installation cavity 110, causing the cable 500 to bend or even entangled with the shell 100.

[0043] Optionally, in another embodiment, there may be multiple ways to install the limit member 400, and the structure of the limit columns 430 on both sides may be omitted. A rubber pad is provided at one end of the limit member 400 close to the cover plate 310 to increase the friction between the cover plate 310 and the limit member 400, so that the limit member 400 is not easily moved. The rubber pad can also provide a buffer for the limit member 400, so that the limit member 400 is not easily damaged by pressure.

[0044] Optionally, in one embodiment, the material of the limiting member 400 may be configured as at least one of polytetrafluoroethylene, polyethylene, polypropylene, and polyamide.

[0045] In this way, the material of the limiter 400 is configured to be one or more of polytetrafluoroethylene, polyethylene, polypropylene, and polyamide. Since these materials have good chemical stability, the limiter 400 can resist most chemical corrosion, have strong temperature resistance, so that the limiter 400 can adapt to a wide temperature range, have a low friction coefficient, and make the surface of the limiter 400 smoother, which can reduce the wear on the cable fixing column 200, have good electrical insulation properties, as well as good rigidity and toughness, and these materials are low in cost, which reduces the production cost of the limiter 400.

[0046] Optionally, in another embodiment, the material of the limiting member 400 is not limited to the above materials, and the material of the limiting member 400 may also be configured as polytetrafluoroethylene propylene.

[0047] Optionally, in one embodiment, the slots 213 on both sides of the casting hole 211 are arranged along the first direction, the sinks 120 on both sides of the installation cavity 110 are arranged along the first direction, and the depths of the through hole 212 and the via hole 112 both extend along the second direction.

[0048] In this way, the card slot 213 and the sinking groove 120 are arranged along the first direction, and the hole depths of the through hole 212 and the through hole 112 are extended along the second direction. When the cable fixing column 200 and the limit member 400 are installed, the positioning of the cable 500 is also completed, making it less likely that the cable 500 will have a skewed installation error, making it convenient for staff to install the cable fixing device, and improving the installation efficiency and quality of the cable fixing device.

[0049] Optionally, in one embodiment, in the first direction, a through hole 311 is provided at opposite ends of the cover 310, a screw hole 130 is provided at opposite sides of the shell 100, the installation cavity 110 is located between the two screw holes 130, one screw hole 130 is provided corresponding to one through hole 311, and the screw 320 passes through the through hole 311 and is connected to the screw hole 130.

[0050] In this way, the through holes 311 are set at opposite ends of the cover plate 310, and the screw holes 130 are set at opposite sides of the shell 100, so that the cover plate 310 applies pressure evenly to the limit member 400 and the cable fixing column 200. Therefore, the limit member 400 and the cable fixing column 200 are not easily offset to reduce the fixing effect of the cable fixing device on the cable 500.

[0051] Optionally, in one embodiment, the number and distribution positions of the through-holes 311 and the screw holes 130 can be various. The through-holes 311 can be opened on the periphery of the cover plate 310, and a plurality of screw holes 130 corresponding to the through-holes 311 can be opened on the periphery of the upper end of the shell 100 to improve the connection stability between the fastener 300 and the shell 100.

[0052] Optionally, in one embodiment, in the up-down direction of the housing 100 , the edge of the through hole 112 extends to the opening 111 .

[0053] In this way, the edge of the through hole 112 is extended along the top of the shell 100 to the opening 111, which makes it easier for the cable 500 to enter or exit the installation cavity 110 along the through hole 112 when installing or removing the cable fixing column 200. When the cable fixing device needs to be disassembled for adjustment and maintenance, there is no need to remove the cable 500 from the cable fixing column 200, thereby reducing damage to the cable 500 and the cable fixing column 200.

[0054] Optionally, in another embodiment, the shape of the through hole 112 may be various, and may be a waist-shaped hole or a square hole communicating with the opening 111 , as long as the cable 500 can be extended.

[0055] It is understandable that those skilled in the art can, under the guidance of the above embodiments, combine various implementation methods in the above embodiments to obtain technical solutions of multiple implementation methods.
