Embodiment
Understand for technical characterictic, purpose and effect to the utility model have more clearly, contrast the embodiment that accompanying drawing specifies the utility model at present.
To shown in Figure 6, advance one first embodiment of cable mouth hermetically-sealed construction like Fig. 1 for the novel cable splice closure of this practicality.In the present embodiment, have on the box body 1 of cable splice closure, advance cable mouth 10 and supply the optical cables turnover by the outward extending columnar cable mouth 10 that advances of box body 1, concrete, in the present embodiment, advance on the base that cable mouth 10 is arranged on the hat type cable splice closure.Advance cable mouth hermetically-sealed construction in the present embodiment and comprise heat-shrinkable T bush 2, sealing socket 3, rubber seal 4 and packing nut 5.
Referring to Fig. 4, sealing socket 3 comprises reducing section 31, thread segment 32 and the cylindrical section 33 that links to each other successively in the present embodiment.Heat-shrinkable T bush 2 one ends are socketed in the into outside of cable mouth 10, and the other end is socketed in the outside of cylindrical section 33.The thread segment 32 of sealing socket 3 is used for and packing nut 5 threaded engagement; Reducing section 31 has the circumferential equally distributed strip gab 311 in a plurality of edges; In the present embodiment, strip gab 311 is an inclined open, i.e. the normal direction inclination certain angle of the direction of bar synform opening 311 and this opening position; Owing to can shrink when the existence of strip gab 311, reducing section 31 receive 5 extruding of packing nut.Rubber seal 4 is cylindrical; Rubber seal 4 is provided with a plurality of cable holes 41 of advancing; Rubber seal 4 is housed in the inside of reducing section 31; Rubber seal 4 is set for ease, is provided with the annular boss 301 of the interior Zhou Yanshen in edge in the reducing section 31 and the inside of the junction of thread segment 32, the end face of rubber seal 4 is pressed against on the annular boss 301.Said; When cooperating with thread segment 32, packing nut 5 is tightened on 32 last times of thread segment; Packing nut extruding reducing section 31 makes reducing section 31 shrink extruding rubber seal 4; Radially deformation takes place in rubber seal 4, advances the hole wall in cable hole 41 and is close to optical cable 6, to reach the effect that is sealed into cable mouth 10.
In the present embodiment, the combination of the thread segment 32 of sealing socket 3 and cylindrical section 33 also locates to be provided with flange 302.Rubber seal 4 a plurality of enter cable hole 41 and evenly distribute at the end face of rubber seal 4, and it is identical to advance the diameter in cable hole 41.A plurality of diameters that enter cable hole 41 of the rubber seal of need understanding 4 also can be different.
The cable splice closure of the utility model advances cable mouth hermetically-sealed construction in use, at first with heat-shrinkable T bush 2 with sealing socket 3 with advance cable mouth 10 and couple together, then optical cable 6 is penetrated urgent nut 5, rubber seal 4, sealing socket 3 successively, advances cable mouth 10 etc. and get into connector box; The urgent nut 5 of screwing then; Urgent nut 5 extruding reducing sections 31 make reducing section 31 compress rubber seal 4, and rubber seal 4 produces radially deformation; Thereby compress optical cable 6, reach the effect that is sealed into cable mouth 10.For the optical cable of not collinear footpath, different cross section, only need to change rubber seal 4 and get final product.
Like Fig. 7 and shown in Figure 8, for the cable splice closure of the utility model advances second embodiment of cable mouth hermetically-sealed construction, different with first embodiment is; In the present embodiment; Sealing socket 3 does not have the reducing section 31 among first embodiment, has only a thread segment 32 and a cylindrical section 33, in order to adapt to the structural change of sealing socket 3; The shape of rubber seal 4 is by the cylindrical taper type that becomes; Less than the diameter over against an end of packing nut 5, like this when cooperating, rubber seal 4 can be more or less freely is extruded in the seal section 32 rubber seal 4 over against the diameter of an end of thread segment 32.Other structures of this embodiment are identical with structure among first embodiment, do not giving unnecessary details.
It will be appreciated that the utility model cable splice closure advances cable mouth hermetically-sealed construction and is not limited to the hat type cable splice closure, be equally applicable to the cable splice closure of other types.The cable splice closure hermetically-sealed construction of the utility model is applicable to various sealing optical fiber cables, and the optical cable of for example blowing, rubber-insulated wire cable, common outdoor optical cable etc. have good applicability, is fit to the sealing of advancing the cable mouth under the various situation.
Cable splice closure at the utility model advances in the cable mouth hermetically-sealed construction; Sealing socket with advance the cable mouth and be connected through heat-shrinkable T bush; Rubber seal is provided with a plurality of cable holes of advancing, and can satisfy the sealing of many optical cables turnover, for the optical cable of different-diameter, different cross section; Only need adaptive more with it rubber seal to get final product, also can change sealing socket in case of necessity.
Combine accompanying drawing that the embodiment of the utility model is described above; But the utility model is not limited to above-mentioned embodiment, and above-mentioned embodiment only is schematically, rather than restrictive; Those of ordinary skill in the art is under the enlightenment of the utility model; Not breaking away under the scope situation that the utility model aim and claim protect, also can make a lot of forms, these all belong within the protection of the utility model.
