It is noted that the terms first, second and the like in the description and in the claims of the present application are used for distinguishing between similar elements and not necessarily for describing a particular sequential or chronological order.

Embodiments as shown in fig. 1 to 7, a two-core outdoor fiber organizer comprises a top cover 1 and a base 2. The base 2 is provided with an inwards concave mounting groove 21, a wire arranging ring is mounted in the mounting groove 21, and optical fibers welded in the mounting groove 21 are wound on the wire arranging ring. Meanwhile, the side wall of the front end of the mounting groove 21 is connected with a pair of plugs 4 made of rubber materials in a sliding manner, and the centers of the plugs 4 are provided with through hole 402; the through hole 402 in the center of one of the plugs 4 is used for leading an optical cable into the mounting groove 21, and the through hole 402 in the center of the other plug 4 is used for leading two fused optical fibers in the mounting groove 21 out of the mounting groove 21, so the sizes and the shapes of the through holes 402 on the two plugs 4 are different, and the specific size and the size can be set according to the sizes of the optical cable and the two optical fibers, so that the optical cable and the two optical fibers are tightly attached to the through hole 402. Since the plug 4 made of rubber has good flexibility and abrasion resistance, when the optical cable or the two-core optical fiber moves due to wind, the local abrasion of the optical cable or the two-core optical fiber can be reduced by the local deformation of the through hole 402.

Meanwhile, the upper end of the plug 4 is also provided with a bump 403, and the bump 403 is slightly higher than the upper end surface of the bottom plate 2. In order to improve the sealing performance between the upper cover 1 and the bottom plate 2, it is usually necessary to seal between the upper cover 1 and the bottom plate 2 by a sealing strip 3. Therefore, when the upper cover 1 is sealed with the base 2 through the sealing strip 3, the sealing strip 3 can extrude the convex block 403, so that the plug 4 is tightly attached to the side wall of the mounting groove 21, and the whole sealing performance of the wiring box is improved.

Specifically, as shown in fig. 3, the sliding connection between the plug 4 and the front end side wall of the mounting groove 21 is realized by arranging a pair of sliding grooves 211 on the front end side wall of the mounting groove 21, and simultaneously arranging grooves 401 on both sides of the two plugs 4, and the sliding connection between the plug 4 and the mounting groove 21 is realized by matching the grooves 401 and the sliding grooves 211, so that the plug 4 is easily detached and replaced when needing to be replaced due to abrasion, and the service life of the wiring box is further prolonged.

Since the through hole 402 is located at the center of the plug 4, the space for the contact position of the through hole 402 is large whether the optical cable or the two-core optical fiber is used; the amplitude of oscillation of the cable and the two-core optical fiber is large when subjected to wind, which increases the abrasion of the cable and the two-core optical fiber. Therefore, as shown in fig. 2 and 3, a pair of support bases 22 are mounted on the front end of the base 2, and the support bases 22 are positioned outside the mounting groove 21. The upper ends of the two supporting seats 22 are provided with supporting grooves 221, and the supporting grooves 221 respectively correspond to the positions of the through hole 402 on the two plugs 4. The support groove 221 is used to support the cable and the two-core optical fiber, thereby reducing the range of motion of the cable and the optical fiber to reduce the wear of the cable and the two-core optical fiber and the through hole 402.

Generally, a fusion-spliced pipe is sleeved at a fusion-splicing position of a spliced optical fiber, and if the fusion-spliced pipe moves in the installation groove 21 frequently, the fusion-splicing quality of the optical fiber in the fusion-spliced pipe is influenced. Therefore, as shown in fig. 2 and 6, the zinc plate 5 is installed in the installation groove 21, the zinc plate 5 comprises a bottom plate 51 and a plurality of zinc plates 52, the zinc plates 52 are zinc alloy plates, the casting performance and the wear resistance are good, and the number of the zinc plates 52 can be adjusted according to actual requirements. The bottom plate 51 is fixed with the bottom of the mounting groove 21, and the zinc plates 52 are fixed on the bottom plate 51 at uniform intervals; the space between the adjacent zinc plates 52 is used for clamping the fusion-spliced pipe sleeved on the fused optical fiber, thereby preventing the fused optical fiber from moving in the mounting groove 21 and being separated from each other.

For a rational layout of the inner space of the installation slot 21, as shown in fig. 1, 2 and 4. The wire arranging ring comprises a plurality of wire arranging seats 6, the wire arranging seats 6 are respectively and fixedly installed on the periphery of the zinc plate 5, the specific number of the wire arranging seats 6 can be set according to actual needs, for example, as shown in fig. 1 and 2, the number of the wire arranging seats 6 is three. Meanwhile, the wire arranging seat 6 comprises a wire winding rod 61 and a baffle 62, one end of the wire winding rod 61 is fixedly connected with the bottom of the mounting groove 21, and the other end of the wire winding rod 61 is provided with a slot 611; an inserting plate 621 is vertically fixed at one end of the baffle plate 62, and the baffle plate 62 is detachably connected with the winding rod 61 through the matching of the inserting plate 621 and the slot 611. When the optical fiber welded in the mounting groove 21 is wound, the baffle plate 62 is firstly removed, and then the welded optical fiber is wound around the zinc plate 5 along the plurality of winding rods 61; after the optical fiber is wound, the blocking plate 62 is inserted into the insertion groove 611 through the insertion plate 621, so as to prevent the wound optical fiber from falling off.

In order to facilitate the detachment of the upper cover 1, as shown in fig. 2, 5 and 7, a plurality of groups of first supporting plates 11 are fixed at the rear end of the upper cover 1, the number of the groups of first supporting plates 11 may be set according to actual needs, for example, as shown in fig. 6, two groups of first supporting plates 11 are provided, and are respectively symmetrically located at two sides of the rear end of the upper cover 1, and supporting shafts 111 are fixed between the first supporting plates 11. Meanwhile, a plurality of groups of second supporting plates 23 are fixed at the rear end of the base 2, the number of the groups of the second supporting plates 23 corresponds to the number of the groups of the first supporting plates 11, and the end part of the second supporting plate 23 is provided with a rotary groove 231. When the upper cover 1 is closed with the base 2, the support shaft 111 is engaged with the rotary groove 231.

Meanwhile, two sides of the front end of the upper cover 1 are fixed with limiting plates 12, and the limiting plates 12 are provided with clamping grooves 121; the two sides of the base 2 are outwardly provided with side plates 24, the side plates 24 are provided with limit grooves 241, and the bottoms of the limit grooves 241 are provided with clamping blocks 242. When the upper cover 1 and the base 2 are covered, the limit plate 12 is positioned in the limit groove 241 and forms a snap connection with the latch 242 through the slot 121; the attachment and detachment of the upper cover 1 are facilitated by the simple structural connection between the upper cover 1 and the base 2. Meanwhile, in order to facilitate the detachment of the upper cover 1, a connecting plate 122 may be obliquely disposed at the end of the limiting plate 12, and the upper cover 1 is detached by pulling the connecting plate 122.

In order to ensure the whole sealing performance of the wiring box, as shown in fig. 5 and 7, sealing stoppers 243 are arranged around the upper end of the mounting groove 21, a sealing groove is arranged around the end of the upper cover 1, and a sealing strip 3 is mounted in the sealing groove; when the upper cover 1 is closed with the base 2, the sealing strip 3 is tightly attached to the sealing stopper 243, so that the overall sealing performance of the wiring box is improved.
