Description

Technical Field

[0001] This utility model relates to the field of optical cable technology, specifically to a convenient-to-use optical cable. Background Technology

[0002] Optical fiber cables are the core carriers for communication network transmission. One end receives high-speed signals from the backbone optical cable, while the other end extends to user terminals such as homes, businesses, and buildings. With their small diameter, flexibility, and ease of installation, they are suitable for complex indoor and outdoor environments and can stably transmit various types of information such as voice, data, and video. They are a key link supporting broadband access, IPTV, smart terminal networking, and other services, enabling communication signals to be accurately delivered from the backbone network to the user side.

[0003] When laying optical cables, there are situations where they are laid along the corners of walls. Traditional optical cables lack protection at the bends, and stress is continuously generated inside the optical fiber bend. Over a long period of use, the accumulated stress can easily lead to fiber breakage, accelerate the aging and cracking of the cable sheath and reinforcement, and reduce the service life of the optical cable. Utility Model Content

[0004] The purpose of this invention is to provide a convenient optical fiber cable to solve the technical problems mentioned in the background art.

[0005] To achieve the above objectives, the present invention provides the following technical solution.

[0006] An easy-to-use optical fiber cable includes a cable consisting of a core wire and an outer jacket fixed to the outside of the core wire. A bending support is fitted onto the cable to provide support and protection for the bending portion of the cable and to limit excessive bending. The bending support includes an arc-shaped support portion and straight support portions. The inner cross-section of the arc-shaped support portion is a butterfly shape matching the outer jacket, and the opening angle of the arc-shaped support portion is an obtuse angle. Straight support portions are fixed at both ends of the arc-shaped support portion, and the two straight support portions are parallel to the wall surfaces on both sides of the wall corner. After the outer jacket moves through the arc-shaped support portion, it is movably fitted into the straight support portions on both sides.

[0007] Preferably, each of the two straight support parts is provided with a fixing module for fixing the two straight support parts to the wall surface on both sides of the wall corner respectively; and when the two straight support parts are fixed to the wall surface on both sides of the wall corner respectively, there is a gap between the wall corner and the arc-shaped support part.

[0008] Preferably, the fixing module adopts L-shaped fastening feet; the upper and lower sides of the two straight support parts are fixed with connecting protrusions, and the end of each connecting protrusion is fixed with an L-shaped fastening foot; each L-shaped fastening foot is provided with a mounting hole for fastening screws to pass through.

[0009] Preferably, the fixing module uses double-sided adhesive tape A; the back of both straight support parts is a flat surface, and double-sided adhesive tape A is fixedly adhered to the flat surface of the back of the straight support part.

[0010] Preferably, a fixing device is provided on the outer layer near its two ends. The fixing device includes a metal elastic sleeve fitted on the outer layer and an adjusting member provided on the metal elastic sleeve for adjusting the opening degree of the metal elastic sleeve. The metal elastic sleeve is composed of a U-shaped part and arc-shaped pressing parts integrally formed on both sides of the U-shaped part. In the natural state, the U-shaped part and the arc-shaped pressing parts on both sides cooperate to press and fasten on the outer layer. An L-shaped opening part is also integrally formed on the two arc-shaped pressing parts, and there is an movable gap between the two L-shaped opening parts. Double-sided adhesive tape B is pasted on the back of the U-shaped part.

[0011] Preferably, the adjusting component includes a T-shaped locking pin and a connecting arm; both L-shaped opening portions are provided with long slots; both ends of the connecting arm are equipped with T-shaped locking pins; the T-shaped locking pins are respectively limited and locked in the corresponding long slots and will not fall off; in the natural state, the two T-shaped locking pins are staggered and distributed at the side ends of the corresponding long slots; a pinch handle is also installed on the connecting arm.

[0012] Preferably, both ends of the outer layer are integrally formed with end handles; the end handles are engaged with the metal elastic sleeve.

[0013] Preferably, the space on the straight support for accommodating the outer layer has a cross-section that is half the butterfly-shaped cross-section of the inner cavity of the arc-shaped support.

[0014] Compared with the prior art, the beneficial effects of this utility model are as follows.

[0015] The optical cable provided by this utility model is specially designed for the corner structure of the wall. By setting up an arc-shaped support part and a straight support part with the cavity cross section adapted to the shape of the outer jacket, and the opening angle of the arc-shaped support part is an obtuse angle, it can form a wrap-around support for the bending part of the optical cable, effectively dispersing bending stress and preventing the optical fiber from breaking due to local stress concentration. The arc design of the arc-shaped support part ensures a smooth transition at the bend, reducing fatigue damage to the optical cable during long-term use and extending the service life of the optical cable.

[0016] This utility model can fix the bending support to the wall on both sides of the corner by setting L-shaped fastening feet or double-sided adhesive A on the two straight support parts, preventing the optical cable bending part from shifting or collapsing due to external force or its own weight, ensuring the long-term stability of the bending shape, and making the installation convenient and quick.

[0017] When the straight support is fixed to the wall, the present invention maintains a gap between the arc-shaped support and the corner of the wall to avoid direct contact between the support structure and the wall. This prevents the arc-shaped support and the corner of the wall from wearing each other and reduces stress concentration caused by hard contact.

[0018] This utility model utilizes an adjusting component to adjust the opening degree of the metal elastic sleeve, enabling flexible adjustment of the fixed point at the end of the optical cable to adapt to different wiring path requirements; the metal elastic sleeve is pressed and fastened onto the outer layer in its natural state to ensure a firm fixation and prevent the optical cable from slipping, while the double-sided adhesive tape B enables quick pasting and fixation, improving the convenience of installation.

[0021] The embodiments of the present invention will now be described with reference to the accompanying drawings.

[0022] In the description of the embodiments of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "connection" and "installation" should be interpreted broadly, wherein "fixed" means that the devices or components are connected to each other and their relative positional relationship remains unchanged after connection. The directional terms mentioned in the embodiments of this utility model are only for reference to the directions in the accompanying drawings, and are used to better and more clearly explain and understand the embodiments of this utility model. They are not intended to indicate or imply that the devices or components referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as limitations on the embodiments of this utility model. Example 1

[0023] Please see Figures 1-7This utility model provides a convenient optical fiber cable, including a cable 1. The cable 1 consists of a core wire 11 and an outer jacket 12 fixed outside the core wire 11. The outer jacket 12 is used for insulation protection outside the core wire 11. A bending support 2 is provided on the cable 1. The bending support 2 provides support and protection for the bending part of the cable 1 and limits the excessive bending of the cable 1. The outer jacket 12 has a butterfly-shaped cross section.

[0024] like Figure 2 As shown, the bending support 2 includes an arc-shaped support part 21 and a straight support part 22. The inner cross-section of the arc-shaped support part 21 is a butterfly shape that matches the outer jacket 12. The opening angle of the arc-shaped support part 21 is an obtuse angle. In this embodiment, the opening angle of the arc-shaped support part 21 is selected as 100°. Straight support parts 22 are fixed at both ends of the arc-shaped support part 21. The two straight support parts 22 are parallel to the wall surfaces on both sides of the corner of the wall. After the outer jacket 12 moves through the arc-shaped support part 21, it is movably fitted into the straight support parts 22 on both sides. In addition, the arc-shaped support part 21 and the straight support part 22 can also be adjusted along the outer jacket 12 to facilitate bending protection of different sections of the cable 1.

[0025] like Figure 2 As shown, the space on the straight support 22 for accommodating the outer jacket 12 has a cross-section that is half the butterfly-shaped cross-section of the inner cavity of the arc-shaped support 21. The straight support 22 can support and protect the portion of the cable 1 that is led out from the end of the arc-shaped support 21. In addition, the semi-open design of the straight support 22 reduces material consumption and lowers manufacturing costs.

[0026] The introduced optical cable utilizes an arc-shaped support section 21 and a straight support section 22 to support and protect the bending section of the cable 1. On the one hand, it directly separates the bending section of the cable 1 from the corner of the wall, preventing the corner from directly squeezing the bending section of the cable 1 and aggravating the damage. On the other hand, the straight support section 22 gives the bending section of the cable 1 a certain arc transition, preventing the cable 1 from being excessively bent and aggravating the damage, effectively improving the service life of the cable 1. Example 2

[0027] Please see Figure 1 The difference between this embodiment and Embodiment 1 is that: Each of the two straight support parts 22 is equipped with a fixing module, which is used to fix the two straight support parts 22 to the wall surface on both sides of the corner of the wall respectively. By using the fixing module to fix the straight support parts 22 to the wall surface on both sides of the corner of the wall respectively, the stability of the cable 1 bend is ensured, and the cable 1 bend is prevented from becoming loose and excessively deformed over a long period of time.

[0028] In addition, when the two straight support parts 22 are respectively attached to the wall surface on both sides of the wall corner, there is a gap between the wall corner and the arc-shaped support part 21, which can prevent the arc-shaped support part 21 from directly contacting the wall corner and damaging the wall corner, thus ensuring the integrity of the corner structure.

[0029] Among them, such as Figure 3 As shown, the fixing module uses L-shaped fastening feet 5. Connecting tabs 4 are fixed on both the upper and lower sides of the two straight support parts 22. Each end of the connecting tab 4 is fixed with an L-shaped fastening foot 5. Each L-shaped fastening foot 5 has a mounting hole 51 for fastening screws to pass through. After the screws are inserted into the mounting holes 51, they are screwed into the wall to fix the two straight support parts 22 to the walls on both sides of the corner.

[0030] By using the connecting tab 4 and the L-shaped fastening foot 5 to form a Z-shaped structure, the gap between the back of the straight support part 22 and the wall surface can be increased, ensuring that the curved support part 21 will not come into contact with the corner of the wall. Example 3

[0031] Please see Figure 6 The difference between this embodiment and Embodiment 2 is that: The fixing module uses double-sided adhesive A6. The backs of both straight support parts 22 are flat, and the double-sided adhesive A6 is fixedly adhered to the flat surfaces of the backs of the straight support parts 22. The double-sided adhesive A6 can firmly stick the straight support parts 22 to the corresponding wall surface, thus fixing the straight support parts 22 to the wall surface. Moreover, the double-sided adhesive A6 fixing method does not require the use of tools for installation, making it simple and convenient to use. In addition, no holes need to be drilled, ensuring the integrity of the wall surface.

[0032] The double-sided adhesive tape A6 has a thickness of 3-5mm. This thickness ensures that the straight support part 22 maintains a certain distance from the wall surface. Figure 7 As shown, this avoids direct contact between the curved support 21 and the corner of the wall. Example 4

[0033] Please see Figure 1 and Figure 5 The difference between this embodiment and embodiment 3 is as follows: A fixing device 3 is fitted on the outer layer 12 near both ends. The fixing device 3 includes a metal elastic sleeve 31 fitted on the outer layer 12 and an adjusting member 32 on the metal elastic sleeve 31 for adjusting the opening degree of the metal elastic sleeve 31. The metal elastic sleeve 31 is composed of a U-shaped part 311 and arc-shaped pressing parts 312 integrally formed on both sides of the U-shaped part 311. In the natural state, the U-shaped part 311 and the arc-shaped pressing parts 312 on both sides are fitted together to press and fasten on the outer layer 12. At this time, the metal elastic sleeve 31 is firmly connected to the outer layer 12, preventing the fixing device 3 from moving freely, ensuring the stability of the fixing point of the cable 1, and improving the fixing effect of the cable 1. An L-shaped opening part 313 is also integrally formed on the two arc-shaped pressing parts 312, and there is an movable gap between the two L-shaped opening parts 313.

[0034] The adjusting component 32 includes a T-shaped locking pin 322 and a connecting arm 323. Both L-shaped opening portions 313 are provided with long slots 321. Both ends of the connecting arm 323 are equipped with T-shaped locking pins 322. The T-shaped locking pins 322 are respectively limited and locked in the corresponding long slots 321. A handle 324 is also installed on the connecting arm 323. In the natural state, the two T-shaped locking pins 322 are staggered and distributed at the side ends of the corresponding long slots 321. At this time, the metal elastic sleeve 31 is firmly fastened to the outside of the outer layer 12 and cannot be adjusted left or right.

[0035] When the position of the fixing device 3 needs to be adjusted according to the laying situation, by pinching the handle 324 and rotating the connecting arm 323, the connecting arm 323 drives the two T-shaped locking pins 322 to move along the corresponding long grooves 321 until the T-shaped locking pins 322 move to the middle position of the long grooves 321. This state is as follows. Figure 5 As shown, the L-shaped opening portions 313 on both sides can be opened, the distance between the two L-shaped opening portions 313 increases, and the arc-shaped pressing portions 312 on both sides are pulled to expand and deform. At this time, there is a movable gap between the metal elastic sleeve 31 and the outer sleeve 12, which makes it easy to adjust the fixing device 3 left and right.

[0036] Double-sided adhesive tape B33 is attached to the back of the U-shaped part 311. When the fixing device 3 is adjusted to a suitable position, the double-sided adhesive tape B33 can be used to stick the U-shaped part 311 to the wall to fix the end of the cable 1.

[0037] When the handle 324 is released, the metal elastic sleeve 31 returns to its elastic state, causing the two T-shaped locking pins 322 to move to a misaligned distribution state, thus achieving automatic fastening of the metal elastic sleeve 31.

[0038] like Figure 5 As shown, both ends of the outer jacket 12 are integrally formed with end handles 13. The size of the end handles 13 is larger than the internal size of the metal elastic sleeve 31, so that the two are locked together to prevent the fixing device 3 from slipping off the end of the cable 1.

[0039] Additionally, it's worth noting that both double-sided adhesive tapes B33 and A6 have protective films attached to them. These films protect the adhesive surfaces of the tapes when not in use. The protective film also has tear tabs, making it easy to peel off the film from the adhesive surfaces of the tapes when in use.

[0040] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention.
