The beneficial effects of the utility model are: termination rack of the present utility model is provided with corresponding marine glue limit at case lid and casing junction, can reach high-intensity water resistance out of doors, the optical cable incoming line and optical cable line outlet and the light bearing structure that arrange, can satisfy simultaneously the jumper connection of optical cable and optical fiber to the family, the rubber-insulated wire folder that arranges also can satisfy the introducing of novel covered wire cable, and this termination rack is easy for installation, safeguards simple.
Description of drawings
In order better to understand content of the present utility model, come the utility model is further described below in conjunction with accompanying drawing.
Fig. 1 is structural representation of the present utility model;
Fig. 2 is vertical view of the present utility model.
Wherein: 1, case lid, 2, casing, 3, hang the wall mounting hole, 4, light bearing structure, 5, fixing single bridge, 6, optical cable inlet wire stationary installation, 7, marine glue limit, 8, naked fine entrance hole, 9, ¢ 40 wire holes, 10, optical cable entrance hole, 11, fusion integrated tray, 12, water joint, 13, optical cable wrapping post, 14, magnet inhales bar, 15, the rubber-insulated wire folder, 16, casing waterproof construction, 17, ¢ 30 wire holes.
Embodiment
Be the structural representation of the utility model termination rack as Fig. 1, include case lid 1 and casing 2, when covering case lid 1, marine glue limit 7 on the case lid 1 closely cooperates mutually with the waterproof construction 16 of casing 2, play and prevent that rainwater from flowing to the effect of box house, casing 2 upper surfaces have two holes, and water joint 12 is installed, be used for fixing from the leading in cable of upper surface inlet wire, the interposition that is positioned at two water joint holes in the casing 2 is equipped with an optical cable inlet wire stationary installation 6, the inlet wire optical cable can be installed and fixed, also good insulation effect can be played; In casing 2 lower surfaces, there is the outer optical cable entrance hole 10 of two ¢ 30 in the left side, and the position, two holes that water joint 12 has been installed with casing 2 upper surfaces is symmetrical, comes as standby wire hole or entrance hole with this; Interposition in casing 2 lower surfaces is equipped with the hole 17 of two ¢ 30, and there is the hole 9 of two ¢ 40 on the right side, and these four holes are used for all that Fiber to the home, and outlet is used.There is the structure 3 of two extension walls casing 2 left and right sides, are used for doing casing 2 and hang that walls use fixedly the time; At box house, eight fixing single bridges 5 are arranged, be used for fixing walking of tail optical fiber and optical cable.
When the light bearing structure 4 in the middle of the casing 2 does not overturn, inhaling bar 14 by magnet links together with casing 2 bottoms, casing 2 normal mounting are on the wall the time, inner light bearing structure 4 can be not random swing, during practical operation, staff is firmly stirred light bearing structure 4 and just can be rotated in 90 degree scopes, on the light bearing structure 4, there are 4 12 cores to melt on the guide rail between the following both ends of the surface and join integrated pallet, can satisfy 48 core optical cables and be drawn out to the family, also can be drawn out to the family as 24 core optical cables, on the light bearing structure 4, there are two ellipse openings 8 as the entrance hole of naked band optical cable in the middle of the following both ends of the surface on the symmetric position, naked band optical cable is introduced 11 li of fusion integrated trays through this hole, in light bearing structure bottom, two wrapping posts 13 are arranged, can be as the coiling of unnecessary optical cable, the tail optical fiber of coiling can overturn simultaneously with the light bearing structure, do not influence normal operation, position, casing 2 lower right corner is provided with rubber-insulated wire folder, the rubber-insulated wire folder is 10mm with the vertical range of the wire hole 9 of casing lower surface ¢ 40, can be under with fiber-to-the-home situation, use covered wire cable to draw the variation that can shake down.
Termination rack of the present utility model can be realized waterproof effect preferably, the corresponding embodiment that insulation effect also obtains, and the stability of inner structure is stronger.Can be used on the fiber-to-the-home outdoor occasion, also can use as the optical cable handing-over, thereby form convenient and practical termination box series.
