Below in conjunction with accompanying drawing 1～9 and to the installation process of above-mentioned optical fiber terminal box (ATB), the structure of above-mentioned optical fiber terminal box is described further:
When above-mentioned optical fiber terminal box (ATB) is installed, adapter 3 is snapped in the adapter draw-in groove 7 on the drain pan 1, then inside being connected tail optical fiber 2 inserts in the adapter 3, the inner tail optical fiber that connects tail optical fiber 2 is coiled in drain pan in the fine district 10 of dish of intermediate plate 6, rubber-insulated wire cable (or circle cable) is imported and exported (as shown in Figure 1) at the optical cable of drain pan 1 and is opened stripping, fix after opening stripping, fixing back length about coiling 0.5m in the fine district 10 of the dish of drain pan 1 gets final product;
After fiber reel winds, can drain pan 1 be fixed on the body of wall by pan head screw;
After rubber-insulated wire cable and tail fiber disc wind, intermediate plate 6 is snapped in the drain pan 1, after installing inside is connected tail optical fiber 2 and rubber-insulated wire cable in 10 (as shown in Figure 1) coiling of the fine district of dish of intermediate plate 6, on intermediate plate 6, connect at fixed area after coiling is good in the welding mode;
After the welding well, with protective cover 5 panel 8 of packing into, the rotary shaft fastener 52 that is about to protective cover 5 snaps in the mounting hole (referring to Fig. 6) of panel 8, can form the rotation and the protection structure of protective cover afterwards, and the unlatching of protective cover and closure state are shown in Fig. 8,9; Again panel 8 is snapped on the drain pan 1, can finish the installation of this optical fiber terminal box (ATB).
The cable structure that advances of the optical cable import and export 9 in the above-mentioned optical fiber terminal box is a groove shape structure, a kind of draw-in groove structure of concrete formation, be to utilize the draw-in groove structure to fix the rubber-insulated wire cable, have outstanding dentation 92 (referring to Fig. 3,4) in the middle of the draw-in groove, the rubber-insulated wire cable directly snaps in the draw-in groove skin of dentation 92 embedding rubber-insulated wire cables afterwards, and the rubber-insulated wire cable is fixed; The circle cable can be imported and exported 9 top at optical cable and fix, after the circle cable is placed on optical cable and imports and exports on a plurality of dentations 93 at 9 tops, prick with line and to pass the line that is provided with on the outer wall of cell wall both sides and prick hole 94 and will justify the cable colligation and fix, line is pricked hole 94 can adopt through-hole structure, as long as the line of convenient binding circle cable is pricked passes; Line is pricked the bottom (as shown in Figure 4) that hole 94 can be arranged on cell wall both sides outer wall, also can be arranged on the middle part or the top of cell wall both sides outer wall, makes things convenient for colligation to get final product.Can a plurality of lines be set at interval on the outer wall of cell wall both sides and prick the hole, be bundled on a plurality of dentations 93 at cell wall top with the convenient more firm round cable that will pass in and out, the line that a strip through-hole structure also can respectively be set on the outer wall of the both sides of cell wall is pricked the hole, on each line bundle hole, a plurality of openings are set at interval and are used to pass the line bundle, can pass line that a plurality of colligations use at interval and prick and get final product, the dentation 93 that optical cable is imported and exported 9 tops has guaranteed the colligation reliability of round cable; Rubber-insulated wire cable and circle cable stagger on short transverse, have solved the problem of insufficient space, and it is clear easy to operate that the optical cable of this structure of while is imported and exported 9 routes, also avoided extruding each other.Compare with having only single draw-in groove structure or band fixed form in the existing fiber termination box product, can solve in the existing fiber termination box and can't in effective fixedly optical cable baring port, guarantee the bending radius of optical cable, thereby influence the problem of transmission quality.
The application scenarios of the optical fiber terminal box of present embodiment (ATB product) is to use in user's family, and ATB hangs wall and height apart from ground is installed generally about 30cm, can touch tail optical fiber unavoidably in the process of using like this, causes the instability of light signal.By increasing transparent protective cover in the panel bottom, protective cover closes after the tail optical fiber 4 of output is inserted well, can effectively protect the tail optical fiber plug to avoid the generation of the problems referred to above.
In sum, the optical fiber terminal box in the embodiment of the invention has effectively protected optical fiber by the adaper plug that adapter connects by clamping protective cover in the panel bottom by protective cover, prevents that the touching tail optical fiber is to the influence of transmission signals in the process of using.And optical cable import and export to adopt the special cable structure that advances, can be easily fixing rubber-insulated wire cable, compatible simultaneously circle cable open stripping and fixing.This optical fiber terminal box is simple in structure, easy to use, has improved the security during jointed fiber uses.
The above; only for the preferable embodiment of the present invention, but protection scope of the present invention is not limited thereto, and anyly is familiar with those skilled in the art in the technical scope that the present invention discloses; the variation that can expect easily or replacement all should be encompassed within protection scope of the present invention.Therefore, protection scope of the present invention should be as the criterion with the protection domain of claim.
