In this application, the lower protruding strip 244 engages with the butterfly introduction unit 3, so that the butterfly introduction unit 3 is relatively fixed in position.

In this application, the cooperation of chimera 11 and gomphosis chamber 20, make chimera 11 can support protective body 2, and make all protective bodies 2 form the polygon, make the product whole more round, it is smooth, the axis that stretches into chimera 11 in the gomphosis chamber 20 is mutually perpendicular with the major axis of the protective body 2 at place, make protective body 2 realize horizontal setting, the space has rationally been saved, because the tight fit can be realized with gomphosis chamber 20 to chimera 11, so can firmly combine, and chimera 11 embedding gomphosis chamber 20 is fairly convenient, or protective body 2 can cup joint on chimera 11 extremely conveniently, not only cup joint during production, can also be manual cup joint.

Since the butterfly-shaped lead-in units 3 are relatively fixed in size (length and width) because they are matched with the optical fiber connectors in the prior art, the size of the protection body 2 is relatively fixed, different embedding parts 1 are needed in order to provide an optical cable with a plurality of butterfly-shaped lead-in units 3, if three butterfly-shaped lead-in units 3 are needed, an embedding part 1 with three embedding bodies 11 is needed, if four butterfly-shaped lead-in units 3 are needed, an embedding part 1 with four embedding bodies 11 is needed, and the like; when butterfly-shaped introducing units 3 with different numbers are provided, the embedded parts 1 with different numbers of embedded bodies 11 are needed, so that the model specification is greatly increased, and great difficulty is brought to stock and storage, in the application, the embedded parts 1 with 2n +2 embedded bodies, 3n embedded bodies, 5n embedded bodies, 7n embedded bodies, 11n embedded bodies, 13n embedded bodies, 17n embedded bodies, 19n embedded bodies and 23n embedded bodies 11 are adopted, so that the stock type is reduced, and the management is greatly facilitated, for example, when the embedded parts 1 are produced, the embedded parts which originally need to be produced have 3 embedded bodies, 6 embedded bodies, 12 embedded bodies and 24 embedded bodies 11, only need to be produced, and thus, when the butterfly-shaped introducing units are actually used, the unnecessary embedded bodies 11 can be broken off as required; if 4, 8, 16 and 32 chimeras 11 are originally needed to be produced, only 32 chimeras 11 are needed to be produced, and therefore, the chimeras 11 which are not needed can be broken off according to needs in actual use; and so on, not to mention. The number of the chimeras is a multiple of each other, and can be obtained by breaking, such as 5, 10, 15 and the like, but not limited to.

Since the above-mentioned protective bodies 2 are relatively fixed in size, although the same engaging part 1 has a large number of engaging bodies 11 and can be adapted to different numbers of protective bodies 2, the size of the protective bodies 2 is relatively fixed, which does not actually make it suitable for different numbers of protective bodies 2, because of size limitation, and after having the tearing grooves 13, the length of the engaging bodies 11 can be properly lengthened and the positions suitable for different sizes are designed, so that it is possible to place a corresponding number of protective bodies 2, for example, the original length is designed to be 24 protective bodies 2, after being broken from the other end of the engaging bodies 11 to the first pair of tearing grooves 13 at one end of the engaging bodies 11, the diameter is reduced, so 12 protective bodies 2 can be placed, after being broken from the other end of the engaging bodies 11 to the second pair of tearing grooves 13 at one end of the engaging bodies 11, the diameter is further reduced, so 6 protective bodies 2 can be placed, after the protective bodies are broken from the other end of the mosaic body 11 to the third pair of tearing grooves 13 at one end of the mosaic body 11, the diameter is further reduced, 3 protective bodies 2 can be placed, and the like, and the mosaic part 1 can be designed according to requirements, and can be extruded out through a sheath extruding machine, the broken mosaic bodies 11 can be recovered and extruded again, and the waste phenomenon is not generated, so-called breaking, the manual breaking can be realized during manual operation, when the machine is produced, the production and scraping can be realized by using a scraper, and the mosaic bodies 11 needing to be removed can be automatically scraped on the scraper when the mosaic part 1 is pulled, so that the application is more flexible. In the prior art, the long axis of the butterfly-shaped introduction unit 3 passes through the axis of the central reinforcing piece, while in the application, the short axis of the protection body 2 passes through the left-right symmetrical axis of the chimera 11, so that the space is more effectively utilized, the product structure is smaller, and the occupied space is less; and the structure is round, and the product performance is more stable and reliable.

Because under the prerequisite that the size of the protective body 2 is unchangeable, because the size of the optical fiber connector is definite, otherwise, the connector is redesigned, so that the product is round, the diameter of the cable core composed of 3 protective bodies and the embedding part is smaller, the diameter of the cable core composed of 6 protective bodies and the embedding part is larger, the diameter of the cable core composed of 12 protective bodies and the embedding part is still larger, the length of the chimera can be increased, in the application, after the chimera is broken from the tearing groove, fewer chimeras can be placed, and the purpose of flexible assembly is achieved.

The method for changing the number of the cores of the butterfly-shaped drop optical cable is not limited to the above, and can be made according to the above statement without creative changes, and the material of the protective body 2 can also be a foaming material, so that the cost is lower, and the product weight is lighter; when one or some butterfly-shaped optical cable units are damaged, appropriate modification can be carried out, for example, when 12 butterfly-shaped optical cable units are damaged, a whole cable can be scrapped in the prior art, and in the application, only the tearing groove 13 at a certain position needs to be broken, so that other butterfly-shaped optical cable units can still be used; the protective layer in this application can also be a thin-walled tube with high elasticity, so that the protective layer can be sleeved on all the protective bodies, and positioning or fixing is also realized. In this application, still can empty some holding chamber 24 in the protective body 2, like this, more nimble, penetrate butterfly-shaped optical cable unit when using also.

The application has the following main beneficial technical effects: the product has smaller diameter, lower material cost, smaller occupied space, lower pole renting cost, more flexible use, more convenient expansion, stronger universality, smoother and more rounded product structure and more stable and reliable product performance.

The above-mentioned embodiments are merely preferred technical solutions of the present invention, and should not be construed as limiting the present invention. The protection scope of the present invention is defined by the claims, and includes equivalents of technical features of the claims. I.e., equivalent alterations and modifications within the scope hereof, are also intended to be within the scope of the invention.
