All other embodiments, which can be made by those skilled in the art based on the embodiments of the application without making any inventive effort, are intended to be within the scope of the application.

Referring to fig. 1,2 and 3, the invisible-light cable provided by the embodiment of the application comprises a cable body 1, a connecting part 2 and an adhesive plate 3; one end of the connecting part 2 is connected to the optical cable body 1, the bonding plate 3 is connected to the other end of the connecting part 2, and the wall surface of the bonding plate 3 away from the optical cable body 1 is provided with a bonding layer 4 for bonding on a carrier.

In the embodiment of the application, the optical cable body 1 is connected to the bonding plate 3 through the connecting part 2, and as the bonding plate 3 is provided with the adhesive layer 4 on the wall surface far away from the optical cable body 1, the adhesive layer 4 is bonded with the bearing objects such as the wall surface and the like during wiring, no melt adhesive or secondary construction is needed, the construction process is relatively simple, the construction cost is relatively low, the requirement that the wiring of the bearing objects such as the wall surface, skirting line and the like can be completed without other mounting accessories and measures for modern home decoration is met, and the actual appearance of the home decoration is not influenced.

The adhesive layer 4 on the adhesive plate 3 of the invisible optical cable can be double faced adhesive, such as 3M transparent traceless foam sponge double faced adhesive.

There are other conventional glues that do not require a melt adhesive. For example, the adhesive layer 4 on the adhesive plate 3 of the invisible optical cable can be a double sided adhesive without a base material, and can be a pressure sensitive adhesive, and the release paper at the other end can be peeled off for adhesion on a carrier such as a wall surface during wiring operation, so that wiring is completed.

Since the load such as the wall surface is usually a relatively flat plane, the bonding plate 3 of the invisible optical cable is in a flat strip structure and is connected with the invisible optical cable through the neck connecting part 2 in order to improve the bonding effect.

Since the optical cable is relatively long, in a preferred embodiment, a plurality of connection portions 2 may be provided on one optical cable body 1 along the length direction thereof, and one adhesive plate 3 may be attached to each connection portion 2. In another preferred embodiment, a plurality of connection portions 2 may be provided on one optical cable body 1 along the length direction thereof, and all the connection portions 2 are connected to the same adhesive plate 3. In another preferred embodiment, a connection part 2 is provided on one optical cable body 1, the connection part 2 is connected with an adhesive plate 3, and the connection part 2 and the adhesive plate 3 extend along the length direction of the optical cable body 1.

In the wiring process, when complex construction environments such as corners, obstacle shields and the like are encountered, construction is inconvenient, and in order to solve the problem, the invisible optical cable provided by the embodiment of the application can fracture the 'neck' connecting part 2 so as to separate the optical cable body 1 and the bonding plate 3 from each other, and at the moment, the invisible optical cable can independently perform wiring operation, and the mode is also convenient for the optical cable to be used as an end.

In order to be able to break the "neck" connection 2, the application also provides various means.

For example, the connection part 2 is configured to be broken by a preset tearing force to separate the cable body 1 and the adhesive plate 3 from each other, as an example.

The preset tearing force may be determined according to the material, the size, etc. of the connection part 2, for example, the preset tearing force is 5N, that is, when the complex wiring environment such as a corner or a wall covered by an obstacle is encountered during wiring, the tearing force of 5N may be applied, the optical cable body 1 and the adhesive plate 3 are separated from each other by tearing the "neck" connection part 2, and then the invisible optical cable may be independently wired.

The material and the dimensions of the connecting portion 2 can be designed according to the actually required tearing force.

For another example, a separating portion for separating the optical cable body 1 and the adhesive plate 3 may be provided on the connecting portion 2; the purpose of separating the optical cable body 1 and the adhesive plate 3 from each other is achieved by the separating portion.

When the connection part 2 is provided with a separation part for separating the optical cable body 1 and the adhesive plate 3, the separation part is a groove provided on the connection part 2. Since the dimensions of the groove are relatively small, the connection portion 2 is more easily torn from the groove when being torn, thereby achieving the purpose of separating the optical cable body 1 and the adhesive plate 3 from each other.

In order to improve the mechanical property of the invisible optical cable, the tensile effect is achieved. As shown in fig. 3, the adhesive sheet 3 is provided with a reinforcing member 5.

In the application scenario with higher requirements on the mechanical properties of the invisible optical cable, a reinforcing member 5 may be added to the bonding plate 3, such as: steel wires, fiber reinforced composites, glass yarns, and the like. The structure can effectively improve the tensile resistance of the invisible optical cable, and the reinforcing piece 5 can be pulled horizontally or twisted.

The invisible optical cable provided by the application can be in a single-tube or multi-tube structure, as shown in the accompanying drawings 1 and 2, one optical cable body 1 is in a single tube, as shown in the accompanying drawings 3, a plurality of optical cable bodies 1 are in multi-tube, and the multi-tube structure is favorable for multi-house branching operation.

Referring to fig. 3, when there are a plurality of the optical cable bodies 1, each optical cable body 1 is arranged in parallel, and each optical cable body 1 is connected to the adhesive plate 3 by a corresponding connection portion 2.

Referring to fig. 1 and 2, the cable body 1 includes a sheath 6 and a colored optical fiber 7, the colored optical fiber 7 being located within the sheath 6.

The cable core of the invisible optical cable can be a multi-core structure or a single-core structure,

For example, in fig. 2, the colored optical fibers 7 in the sheath 6 are provided with a plurality of multi-core structures, and if a splitting operation is needed, the multi-core structures can be selected. In fig. 1, the colored optical fiber 7 in the sheath 6 is provided with one and has a single-core structure.
