Description

Technical Field

[0001] This application relates to the field of optical communication technology, and in particular to a cable. Background Technology

[0002] In FTTR applications, self-adhesive optical cables have the characteristics of small size and self-adhesion. Considering the current industry demand for the concealment and aesthetics of optical cables in indoor applications, the smaller the size of the optical cable, the better, and the more concealed the wiring on the wall, the better.

[0003] To ensure that self-adhesive optical cables can be used firmly and for a long time, sufficient bonding surface is required. Therefore, flat structures are widely used in them. In indoor application scenarios, due to space limitations, there are often many complex wiring scenarios, such as inside corners, outside corners, and plane corners.

[0004] Common flat fiber optic cables present numerous application problems in this scenario. For example, at corners, common flat fiber optic cables are prone to warping, resulting in poor adhesion between the corner and the wall, severely affecting the overall aesthetics of the cabling and the stability of the adhesive.

[0005] For flat optical cables with high stiffness of the reinforcing members, at inside and outside corners, the optical cable may not adhere firmly to the wiring surface (such as a wall) due to excessive stress on the reinforcing members.

[0006] Furthermore, in indoor applications, self-adhesive optical cables are not always attached to regular flat surfaces. In some curved or corner-based cabling scenarios, the flat bottom of conventional flat optical cables is difficult to adapt to the cabling requirements of such special scenarios. Long-term laying in these places will cause the adhesive to peel off due to uneven stress, affecting the aesthetics of the optical cable. Summary of the Invention

When the cable passes through an inside corner or an outside corner, separating the reinforcing unit can greatly reduce the cable stress and make the cable fit well with the wiring surface.

Detailed Implementation

[0050] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0051] See Figure 1 , Figure 2 and Figure 3 As shown, this application embodiment provides a cable including an adhesive layer 400, an optical unit 100, a reinforcing unit 200, and a connecting portion 300. For ease of understanding, the length extension direction of the adhesive layer 400 or the optical unit 100 is taken as the first direction (marked as the Z direction), the thickness extension direction of the adhesive layer 400 is taken as the third direction (marked as the Y direction), and the width extension direction of the adhesive layer 400 is taken as the second direction (marked as the X direction). The third direction, the second direction, and the first direction are perpendicular to each other. The reinforcing unit 200 and the optical unit 100 both extend along the first direction. The reinforcing unit 200 and the optical unit 100 are arranged at intervals, so that there is a gap between the reinforcing unit 200 and the optical unit 100. The reinforcing unit 200 can improve the tensile strength of the cable, enabling it to withstand greater construction tension and reducing or avoiding damage to the optical fiber caused by excessive traction force during the laying and construction process. Among all the reinforcing units 200, at least one reinforcing unit 200 is distributed with the optical unit 100 in the second direction, and the reinforcing unit 200 and the optical unit 100 are connected by a connecting part 300. The two ends of the connecting part 300 in the second direction are respectively connected to the reinforcing unit 200 and the optical unit 100, so that the cable is flat. The adhesive layer 400 has two opposing walls in the third direction, one of which is the first wall 420. The first wall 420 is bonded to at least one of the optical unit 100, the connecting part 300 and the reinforcing unit 200. The cable can be laid and fixed by the adhesive layer 400.

[0052] The cable provided in this application connects the optical unit and the reinforcing unit together to form a flat shape through a connector. With this design, the cable has strong tensile strength under the protection of the reinforcing unit at places without corners. When the cable passes through a flat corner, cutting off the connector allows the reinforcing unit to be easily separated from the optical unit, and using only the optical unit for the corner effectively prevents the cable from warping during the cornering process. When the cable passes through an inside or outside corner, separating the reinforcing unit can significantly reduce cable stress and ensure good fit between the cable and the wiring surface. In curved wiring scenarios, since the connector can be bent, the optical unit and the reinforcing unit can exhibit a certain curvature along a second direction to a certain extent, improving the reliability of the cable in curved wiring scenarios.

[0053] It is understood that the connecting part 300 in this application can be as follows: Figure 3 The continuous structure extending along the first direction in this application may also include a plurality of connecting elements, which are distributed at intervals along the first direction, and each connecting element is connected to the reinforcing unit 200 and the optical unit 100 at both ends in the second direction.

[0054] It is understood that the cable provided in the embodiments of this application can be an optical cable. Of course, in some examples, the cable can also be a hybrid of optical cable and electrical cable.

[0055] See Figure 1 As shown, the optical unit 100 includes an optical fiber 110 and a first sheath layer 120, with the optical fiber 110 located within the first sheath layer 120. The first sheath layer 120 wraps around the optical fiber 110 along its entire length, providing isolation and protection to the optical fiber 110 and preventing damage from collisions or compression with the external environment during transportation and deployment.

[0056] It is understood that the number of optical units 100 in the cable shown in the figure of this application is one, but in fact the number of optical units 100 can be set as needed.

[0057] The number of optical fibers 110 can be selected according to actual needs. For example, the number of optical fibers 110 is 1-24 cores.

[0058] The material of the first sheath layer 120 can be selected from various materials, such as low-smoke halogen-free flame-retardant polyolefin, polyvinyl chloride, polyurethane, polytetrafluoroethylene and nylon.

[0059] See Figure 1As shown, the reinforcing unit 200 includes a reinforcing member 210 and a second sheath layer 220, with the second sheath layer 220 covering the surface of the reinforcing member 210.

[0060] The material of the second sheath layer 220 can be selected from various materials, such as low-smoke halogen-free flame-retardant polyolefin, polyvinyl chloride, polyurethane, polytetrafluoroethylene and nylon.

[0061] The reinforcing member 210 can be made of various materials, such as steel wire, steel strand, aramid-reinforced plastic rod, fiber-reinforced plastic flexible rod, glass fiber-reinforced plastic rod, polyethylene rod, polyethylene yarn, aramid yarn, glass yarn, and glass fiber. The glass fiber can be bare fiber (uncoated) or coated glass fiber.

[0062] The connecting part 300 can be made of a variety of materials, such as low-smoke halogen-free flame-retardant polyolefin, polyvinyl chloride, polyurethane, polytetrafluoroethylene, or nylon.

[0063] In one possible implementation, the first sheath layer 120, the second sheath layer 220, and the connecting part 300 can be made of the same type of material.

[0064] In one possible implementation, the outer diameter of the long axis of the cable can be less than or equal to 8 mm, and the outer diameter of the short axis can be less than or equal to 5 mm.

[0065] In one possible implementation, the reinforcement 210 is partially located outside the second sheath layer 220, such that the reinforcement 210 may not be partially covered by the second sheath layer 220. Specifically, the second sheath layer 220 has a receiving groove extending in a first direction on its sidewall, and the reinforcement 210 is disposed in the receiving groove, so that a portion of the sidewall of the reinforcement 210 is not covered by the second sheath layer 220.

[0066] In one possible implementation, the cross-sectional area of ​​the reinforcing member 210 located outside the second sheath layer 220 is less than 50% of the total cross-sectional area of ​​the reinforcing member 210, such as 45%, 40%, 35%, etc.

[0067] In one possible implementation, the thickness of the connector can be limited to make it susceptible to damage, thereby making the optical unit and the reinforcing unit easy to separate without exposing the optical fiber during the separation process. The optical unit has an independent sheath layer to protect the optical fiber, ensuring good reliability when the optical unit is used alone.

[0068] Specifically, see Figure 1As shown, the thickness b of the connecting part 300 is less than the thickness a of the optical unit 100, so that in the third direction, a deformation space 320 is formed on the upper and / or lower side of the connecting part 300. The deformation space 320 not only makes it easier for the construction worker to break the connecting part 300 to separate the reinforcing unit, but also allows the flat cable to deform flexibly to fit on the curved surface area when wiring in the curved area, so that it is not easy to lift up.

[0069] Wherein, the thickness b of the connecting part 300 is: the distance from the upper surface to the lower surface of the connecting part 300 in the third direction;

[0070] The thickness 'a' of the optical unit 100 is the distance from the upper surface of the optical unit 100 to the first wall surface 420 in the third direction.

[0071] It is understandable that the relationship between a and b can be determined according to actual needs. For example, in one possible implementation, the thickness b of the connecting part 300 is not greater than 40% of the thickness a of the optical unit 100. For example, b = 40% a, or b = 35% a, or b = 30% a, or b = 25% a, etc.

[0072] In one possible implementation, see Figure 1 As shown, the optical unit 100 is provided with reinforcing units 200 on both sides in the second direction to protect the optical unit 100 from both sides.

[0073] In one possible implementation, see Figure 1 As shown, the optical unit 100 and the reinforcing unit 200 distributed in the second direction are both bonded to the first wall surface 420, or the optical unit 100, the connecting part 300 distributed in the second direction and the reinforcing unit 200 are all bonded to the first wall surface 420. In the corner wiring scenario, the cable can be bent to two planes (in this case, the cable is still a whole, and since the connecting part is not damaged, good tensile strength can be guaranteed while pasting along the corner), or the connecting part on one side can be cut off. At the cut-off connecting part, the cable can be bent to two planes, and the cable can be pasted and wired along the corner on two planes, increasing the contact area between the cable and the object being pasted, thereby improving the wiring reliability in this scenario.

[0074] In one possible implementation, in the second direction, at least two of the reinforcing units 200 are located on the same side of the optical unit 100, and two adjacent reinforcing units 200 are connected by a connecting portion 300; as Figure 9 As shown, two reinforcing units 200 are provided on the same side of the optical unit 100, which can further provide better support and protection for the optical unit 100.

[0075] In one possible implementation, among all the reinforcing units 200, at least one reinforcing unit 200 is located above the optical unit 100 in a third-dimensional direction. Because it is far from the adhesive layer 400, it does not need to be adhered to the adhesive layer 400. Therefore, this reinforcing unit 200 is connected to the optical unit 100 via a connecting portion 300. Figure 10 As shown, there are two reinforcing units 200 located above the optical unit 100 in the third direction, and two reinforcing units 200 arranged in the second direction, for a total of four reinforcing units 200 distributed around the outer periphery of the optical unit 100, which can protect the optical unit 100 in multiple dimensions.

[0076] It should be noted that when there are multiple reinforcing units 200, the reinforcing element in at least one of the reinforcing units 200 can be set as an optical fiber as needed, so that the reinforcing unit 200 actually becomes an optical unit 100. Since there are multiple reinforcing units 200, when it is necessary to cut a reinforcing unit 200 for turning or other operations during actual wiring, the reinforcing unit 200 that is an optical unit 100 does not need to be cut, but other reinforcing units 200 should be cut to achieve wiring and ensure the wiring effect.

[0077] In one possible implementation, the cross-section of the optical unit 100 is circular, square, semi-circular, or other irregular shapes, such as U-shaped. Figure 1 As shown, the cross-section of the optical unit 100 is U-shaped, specifically a shape with a circle at the top and a trapezoid at the bottom. It should be noted that the upper circle in this shape can be a semicircle or a minor arc. Alternatively, it can be a circle at the top and a trapezoid at the bottom, etc. The cross-section of the reinforcing unit 200 is circular, square, or semicircular, or other irregular shapes, such as U-shaped. Figure 1 As shown, the cross-section of the optical unit 100 is U-shaped, specifically a shape with a circle at the top and a trapezoid at the bottom. It should be noted that the upper circle in this shape can be a semicircle or a minor arc. Alternatively, it can be a circle at the top and a trapezoid at the bottom, etc. By reasonably controlling the shapes of the optical unit 100 and the reinforcing unit 200, the bonding area of ​​the optical unit 100 and the reinforcing unit 200 can be adjusted, thereby improving the adhesion between the adhesive layer 400 and the optical unit 100 and the reinforcing unit 200.

[0078] In one possible implementation, the connecting part 300 is provided with a first easy-tear groove 310 on the upper and / or lower surfaces in a third direction, and the first easy-tear groove 310 extends along a first direction; by setting the first easy-tear groove 310, the damage point of the connecting part 300 can be controlled, and setting the damage point at a position away from the light unit 100 can better protect the light unit 100 from being damaged.

[0079] In one possible implementation, a second easy-tear groove 410 is provided on the adhesive layer 400 corresponding to the connecting portion 300, and the second easy-tear groove 410 extends along the first direction; by providing the second easy-tear groove 410 on the adhesive layer 400, the characteristics of easy separation between the light unit 100 and the reinforcing unit 200 can be further improved, and the light unit 100 can be separated more conveniently in actual construction and use.

[0080] Adhesive layer 400 can be hot melt adhesive or pressure-sensitive adhesive.

[0081] In one possible implementation, the adhesive layer 400 has two opposing walls facing the third direction, one of which is a second wall 430, on which a release film 500 is disposed.

[0082] The release film 500 can be made of a variety of materials, such as polyethylene terephthalate (PET) release film, polyethylene (PE) release film, polypropylene (PP) release film, polyvinyl chloride (PVC) release film, paper-based release film, and composite release film.

[0083] The following examples further illustrate this point.

[0084] Example 1:

[0085] This embodiment provides a cable including an optical unit 100, two reinforcing units 200, and a connecting portion 300. The optical unit 100 and the reinforcing units 200 are connected together via the connecting portion 300. The optical unit 100 includes a first sheath layer 120 and optical fibers 110 located therein, the number of optical fibers 110 being less than or equal to 24. The reinforcing unit 200 includes a reinforcing member 210 and a second sheath layer 220 covering the reinforcing member 210.

[0086] For multi-core structures, there can be two sheath layers made of different materials.

[0087] The first sheath layer 120, the second sheath layer 220, and the connecting part 300 can be made of the same type of material to ensure the robustness of each part. The reinforcing member 210 can be one of the following: steel wire, steel strand, aramid-reinforced plastic rod, fiber-reinforced plastic flexible rod, glass fiber-reinforced plastic rod, high-strength polyethylene rod, high-strength polyethylene yarn, aramid yarn, glass yarn, or glass fiber rod. The above structure can be formed by extrusion.

[0088] See Figure 1 As shown, the lower edges of the optical unit and the two reinforcing units are aligned in a straight line. The lower edges of the optical unit and the reinforcing units are planar, and a pressure-sensitive adhesive layer is applied to these surfaces. Alternatively, the lower edges of the optical unit and the reinforcing units can be non-planar. In this case, a portion of the adhesive layer can be embedded into the gap between the optical unit and the reinforcing units, thereby increasing the bonding area of ​​the adhesive layer. See [link to diagram]. Figure 4 For optical units and reinforcing units with planar lower edges, part of the adhesive layer can be embedded in the gap between the optical unit and the reinforcing unit to further increase the bonding area of ​​the adhesive layer. Furthermore, the adhesive layer can be simultaneously bonded to the optical unit, reinforcing unit, and connecting part, and even the connecting part can be placed on the lower edge plane, see [reference needed]. Figure 5 On the other side of the adhesive layer, namely the second wall surface 430, a release film 500 is provided. The main function of the release film layer is to separate the adhesive layer from the other layer of cable when the cable is stored in a roll, so as to prevent the adhesive layer from sticking the entire roll of cable together and making it impossible to lay.

[0089] During construction and deployment, the adhesive layer is bonded to the object by tearing off the release film.

[0090] When laying out in a straight line, it can be directly pasted for construction.

[0091] At the corner, a specific cutting tool can be used to cut open the connecting part and the corresponding adhesive layer, removing a section of the reinforcing unit. See [link / reference]. Figure 3 By cutting off the light unit portion of the reinforcing unit to make the corner, it can be ensured that the cable still fits well with the wall when making a corner on a plane, without any lifting phenomenon, and is not affected by the stress of the reinforcing component when making corners at inside and outside corners.

[0092] In curved cabling scenarios, because the connection points can be bent, the optical unit and reinforcement unit can exhibit a certain degree of curvature along the X-axis, increasing the contact area between the cable and the curved surface 600, thereby improving the reliability of the cable in curved cabling scenarios. (See...) Figure 6 ;

[0093] In corner cabling scenarios, one side of the connector can be cut off (leaving the adhesive layer). At the cut-off connector location, the cable can be bent to two planes, allowing it to be attached and routed along the corner on both surfaces. This increases the contact area between the cable and the right-angled object (70°), thereby improving cabling reliability in this scenario. See [link / reference]. Figure 7 .

[0094] Example 2:

[0095] Based on Embodiment 1, a second easy-tear groove 410 is added to one or both of the first wall surface 420 and the second wall surface 430 of the connecting part 300 and the adhesive layer 400. By setting the second easy-tear groove 410, the failure point of the connecting part 300 is controlled. Setting the failure point away from the optical unit 100 can better protect the optical unit 100 from damage, while reducing the tearing force when separating the reinforcing unit 200. After tearing off the release film 500, the reinforcing unit 200 and the optical unit 100 can be separated without tools, and then cut with scissors to achieve independent use of the optical unit 100 at the corner, ensuring good performance at planar corners, inside corners, and outside corners. At the same time, the addition of the second easy-tear groove 410 will also reduce the bending stress at the connecting part 300, better adapting to non-curved surfaces and corner wiring scenarios. See Figure 8 .

[0096] Example 3:

[0097] Based on Example 1, multiple reinforcing units 200 are added, and they are simultaneously connected to the optical unit 100 or other reinforcing units 200 via connecting parts 300. Increasing the number of reinforcing units 200 improves the tensile strength of the cable, allowing for use in special scenarios with high tensile forces. Similarly, the reinforcing units 200 can be cut off during bending to ensure the overall bending resistance of the cable. For structures with multiple reinforcing units 200, all reinforcing units 200 and the optical unit 100 can be aligned on the same straight line, with an adhesive layer 400 adhered to the bottom and a release film 500 provided. (See...) Figure 9 .

[0098] Alternatively, some reinforcing units 200 and optical units 100 can be arranged on the same straight line, while other reinforcing units 200 can be arranged in other directions around the optical units 100 to ensure that the overall width of the cable is not too large. Adhesive layers can be pasted on the bottom of some reinforcing units 200 and optical units 100, and release films can be applied. (See...) Figure 10 .

[0099] Example 4:

[0100] Based on Example 1, see Figure 11 The reinforcing member 210 can be partially placed outside the second sheath layer 220. The portion placed outside the second sheath layer 220 is adhered to the adhesive layer 400, which can protect the reinforcing member 210 to a certain extent. The cross-sectional area of ​​the reinforcing member 210 placed outside the second sheath layer 220 is less than 50% of the total cross-sectional area of ​​the reinforcing member 210.
