Further improvement to technical solutions of the utility model, the protective shell consist of two parts, and cut-off rule edge is axial,
Protective shell end face is in the junction both ends overlapping region Jun You, and corresponding protrusion is respectively set in overlapping region, groove is fastened.?
In use, the protrusion fastened on protective shell, groove can be opened first, protective shell is separated, sealing column is taken out, further according to cable outer diameter
Corresponding size adjusting, the more convenient operation of size adjusting are carried out to sealing column internal diameter and protective shell end face opening.
At least one elastic seal ring is arranged on the protective shell in further improvement to technical solutions of the utility model.
It is possible that the inaccurate problem of size, once protective shell size is slightly smaller, closeouts go out with optical cable when due to work pieces process
Leakproofness between entrance will receive influence, pass through the addition of elastic seal ring, it is ensured that between closeouts and optical cable entrance
Leakproofness.
Further improvement to technical solutions of the utility model, the rubber tube are round tube, innermost layer rubber bore
For 8mm, outermost layer rubber bore is 12mm.It is configured according to common cylindrical shaped optic cable diameter 8mm-12mm, day can be met
Primary demand in being often used.
Further improvement to technical solutions of the utility model, the protective shell material are duroplasts.Using duroplasts material
Matter, easy to make, low cost；When in use, it is squeezed and is unlikely to deform, facilitate and be pressed into optical cable inlet and outlet.
Compared with prior art, the utility model has the beneficial effects that
(1) rubber tube in the utility model sealing column can be stripped along opening, protective shell end face can along tear line into
Row is split, so that the internal diameter of sealing column and protective shell end face opening can carry out phase according to different size optical cables in the utility model
Size is answered to adjust, single closeouts adapt to different-diameter optical cable, and operability is good；And between sealing column, protective shell and optical cable
And good airproof performance between protective shell and sealing column, there is protective effect to optical cable, the sealing of cable splice closure inlet and outlet also can be improved
Property, anti-moisture effect is good.
(2) protective shell in the utility model and the rubber tube in sealing column can be set according to different types of optical cable
It sets, in use, connecting of the different types of optical cable in cable splice closure can be realized according to actual needs.
(3) unused optical cable inlet and outlet on cable splice closure, can be blocked with the closeouts of the utility model.
