Embodiment

[0049] a kind of like figure 1 The split butterfly cable shown specifically includes:

[0050] Two cable units 10 are fitted together to form a complete butterfly cable;

[0051] The cable unit 10 is specifically as figure 2 As shown, it includes a sheath 100, a waterproof protective layer 201, a tape layer 200 and an optical fiber 300, and optionally a strengthening member 400, and the sheath 100 is made of elastic PE material;

[0052] The sheath 100 is provided with a cavity for accommodating the tape layer 200 and the optical fiber 300, the optical fiber 300 is arranged in the cavity and fixed by the tape layer 200, and the waterproof protective layer 201 is arranged on the outer surface of the tape layer 200, In this embodiment, a strengthening member 400 is provided at the axis of the tape layer 200 of the cable unit 10, and the optical fiber 300 is evenly arranged outside the strengthening member 400 in the circumferential direction;

[0053] The sheath 100 is exten...

Abstract

The invention belongs to the field of optical cables, and particularly relates to a split type butterfly cable. The butterfly cable comprises two cable units which are cooperatively installed to form a complete butterfly cable; the cable unit sequentially comprises a sheath, a waterproof protection layer, a wrapping tape layer and optical fibers from outside to inside. The sheaths extend to be provided with L-shaped connecting parts, and the connecting parts of the sheaths of the two cable units are matched with each other; the connecting part is provided with a platform, a clamping groove is formed in the connecting position of the bottom end of the side wall of the platform and the platform, a clamping protrusion matched with the clamping groove is arranged on the outer edge of the platform, and a metal sheet used for clamping matching is arranged on the platform. The metal sheet comprises a clamping part and an embedding part, one end, opposite to the side wall of the platform, of the clamping part is connected with the embedding part, the embedding part extends and is embedded into the platform, and the height of the lower end face of the clamping part is smaller than or equal to the thickness of the clamping part. According to the invention, branching and doubling operations can be effectively, efficiently and quickly carried out; after branching, each cable unit is complete in structure, good in sealing performance, good in mechanical performance and not easy to damage; the overall structural design is reasonable.

Description

technical field [0001] The invention belongs to the field of optical cables, in particular to a split butterfly cable. Background technique [0002] Butterfly cable is a common type of fiber optic cable, which is usually used as an overhead fiber optic cable or a home fiber optic cable. [0003] However, when it is used as a home optical cable, there are problems such as difficult line distribution and low effective utilization rate. Because in the actual building layout and wiring process, the utilization rate of the super multi-core fiber in the butterfly cable is usually less than 50%, because the butterfly cable is usually not so much when it is drawn out from a communication provider port and connected to an indoor terminal. The number of cores, and the branching operation of the butterfly cable is much more complicated than that of the round cable, and the physical branching is easy to cause damage to the mechanical structure of the butterfly cable, making it unable t...
