The cable easy to separate as shown in fig. 1-3 comprises a sheath 1 and an optical unit 2, wherein the cable is flat, the sheath comprises two symmetrical and outwards arched C-shaped end portions 3, the lower ends of the two C-shaped end portions are connected through a straight portion 4, the upper end of the sheath is open, namely, the sheath is composed of the two C-shaped end portions and the straight portion connecting the lower ends of the two C-shaped end portions, in actual production and manufacturing, the two C-shaped end portions and the straight portion are integrally formed to improve the mechanical performance of the whole sheath, a containing cavity 5 is formed between the two C-shaped end portions and the straight portion, a limiting block 6 is arranged in the containing cavity, the left end and the right end of the limiting block are inwards recessed, in the embodiment, the limiting block is inwards recessed in an arc shape, through holes 7 along the axial direction of the cable are respectively formed between the limiting block and the C-shaped end portions on the left side and the right side, the optical unit is arranged in the through holes, and the limiting block plays a role of fixing the optical unit.

The optical unit is a single beam tube or a plurality of parallel beam tubes, and a single or a plurality of optical fibers are arranged in each beam tube.

The cable with the structure is easy to combine and separate, the limiting block is filled after the optical unit is arranged in the through hole, when the optical unit is damaged and needs to be replaced, the limiting block is pulled out, and the limiting block is filled again after replacement, so that the replacement is convenient and simple; in addition, after the optical unit is pulled out, other energy lines or signal lines are arranged in the through hole, so that functional replacement is realized, and repeated wiring is avoided. For making the stopper pull out from the holding chamber easily, also for playing better protection to the optic fibre simultaneously, the stopper chooses the material that the elasticity is better for use, selects to use high-elastic silica gel in this example.

The cable is laid and used, the cable can be extruded inevitably, and due to the structural characteristics of the cable, pressure is mainly concentrated on the upper side and the lower side, so that the through hole is further designed to be elliptical, and two ends of the beam tube are abutted to two ends of a short shaft of the through hole. When the cable is pressed by the upper side and the lower side, the short shaft of the through hole is lengthened, the beam tube is separated from the limit of the two ends of the short shaft of the through hole, can move up and down in the through hole and is not easy to damage.

Further, a conductive line belt 8 is arranged between the upper end openings of the two C-shaped end portions, the conductive line belt is flat and strip-shaped, the conductive line belt is formed by extruding resin after a plurality of conductive lines are arranged in parallel, the conductive lines sequentially comprise a copper conductor, an inner insulating layer, a shielding layer and a sheath from inside to outside, and the conductive line belt is embedded between the upper end openings of the two C-shaped end portions through friction force between the sheath and the resin; the setting in conducting wire area had both played the opening of closed C shape tip upper end for the cable is the closure, improves the planarization of cable and prevents that rainwater, dust from getting into the inside effect of cable, can improve the compressive property of cable again, and the current space of cable has also obtained make full use of.

In order to improve the embedding degree of the conductive wire belt and the sheath and simultaneously enable the embedding operation to be more convenient, furthermore, a groove 9 is axially arranged at the upper end of the C-shaped end part along the cable, bulges 10 matched with the groove are arranged at the two ends of the conductive wire belt, and the bulges are inserted into the groove to realize the connection of the conductive wire belt and the sheath. Through recess and bellied gomphosis, the outward appearance of conducting wire area and sheath is more level and smooth, and the integration degree is higher, and has externally arranged the conducting wire area, and photoelectric transmission can be realized simultaneously to the cable, and the conducting wire area also can be replaced as required for other functional lines such as optical fiber area or signal line area.

When the conductive wire band needs to be replaced, the conductive wire band is directly pulled out, and a new wire band (a functional wire, such as a ribbon or a signal wire band) is embedded. When the optical unit needs to be replaced, the conductive wire belt is pulled out firstly, then the limiting block is pulled out, and after the optical unit is replaced, the replacement of the optical unit can be realized after the operations are carried out according to the reverse sequence. The existing optical unit or electric unit extruded in the sheath directly can only be replaced integrally when a certain core wire needs to be replaced due to reasons such as damage, and the like, so that the waste is large.

The stopper is whole difficult at the holding intracavity removal, for making the operation more convenient, the stopper comprises the left stopper 61 and the right stopper 62 of symmetry, the outer end of left side stopper and right stopper is inwards sunken, the mutual butt in inner. In addition, in order to prevent external water vapor from permeating into the cable and influencing the performance of the optical fiber, a water blocking material is arranged in a gap between the bundle tube and the optical fiber.
