Detailed Description

The present invention will be further explained with reference to the accompanying drawings.

As shown in fig. 1-2, the present embodiment provides an embedded indoor optical cable that can be repeatedly peeled, including an optical fiber bundle core and an outer sheath 1. The optical unit cable core comprises a plurality of strands of optical fiber bundle units 2, optical communication units 3 are arranged in the optical fiber bundle units 2, and the optical communication units 3 are optical fibers or tight-buffered optical fibers. The outer sheath 1 is provided with an embedded stripping device 4, the stripping device comprises an outer brace 4 and an inner embedded groove 6, the outer brace 4 is arranged on the outer side of the outer sheath 1, and the inner embedded groove 6 is arranged on the inner side of the outer sheath. Wherein, the tail end of external stay links to each other with the oversheath, also can be with oversheath whole separation, specifically depends on operating condition and decides. The inner side of the external bracing piece is provided with a knife edge 7 with a sharp-cornered front end, the embedded groove is internally provided with a groove 8 matched with the knife edge shape, the knife edge 7 and the groove 8 form embedded assembly, and the knife edge 7 and the groove 8 can be completely attached and assembled into a whole. The material of the inner embedded groove 6 is flexible plastic, the material of the inner embedded groove is consistent with that of the outer sheath, the knife edge 7 is made of metal material and is arranged along the length direction of the outer brace, the outer brace 4 is plastic, and the plastic is formed by preprocessing, and is cooled and solidified with metal into a whole after being melted.

When stripping the optical cable: the external stay 4 is pulled outwards, the optical cable sheath 1 and the groove 8 are both made of soft plastics, the metal knife edge 7 can be separated from the groove 8 and linearly cuts the outer sheath 1, the external stay 4 is separated from the internal groove 6, and the purpose of stripping the optical cable sheath is achieved.

When the optical cable is closed: after the optical cable is welded, the knife edge 7 is plugged along the previous cut, the knife edge extrudes the groove 8 to deform, and then the groove 8 is pressed to be attached, so that the optical cable keeps the previous integrity.

In this embodiment, the knife edge is preferably a diamond knife edge, the shape of the groove is matched with that of the knife edge, when the optical cable is closed, the diamond knife edge 7 can be extruded to the diamond groove 8 to deform, so that the optical cable enters the groove to be attached, and a coating relation is formed between the diamond groove and the diamond knife edge to keep the positions of all parts unchanged, so that the integrity of the optical cable is ensured.

In this embodiment, a water blocking layer 9 is coated outside the optical unit cable core. The water-resistant layer 9 is water-resistant yarn or water-resistant tape. The outer sheath 1 is a polyethylene outer sheath or a low-smoke halogen-free flame-retardant outer sheath.

The utility model discloses compact structure is suitable for 5G and indoor etc. special use operating mode, can satisfy constructor and open fast and shell the optical cable and carry out work such as butt fusion, avoids the use of various instruments, and can repeatedly open the oversheath of optical cable and shell and be closed, and the connection and the maintenance of easy indoor optical cable have improved work efficiency greatly.
