The optical fiber ribbon cable that is used for optical fiber distributing equipment is driven the stripping protective device
Technical field
The utility model relates to the electrical power wiring assembly of telecommunication apparatus, relates in particular to the optical fiber ribbon cable that is used for optical fiber distributing equipment and drives the stripping protective device.
Background technology
Optical fiber distributing equipment is the distributing connection equipment of optical cable and optical communication equipment, and it comprises that optical cable is fixing and is connected distributor and tail fiber disc winding apparatus with protective device, optical fiber terminating apparatus, tail optical fiber.But stripping is fixed, opened to existing optical cable, the protective device capacity is more fixing mostly; the core number that can not the flexible adaptation optical cable and the radical of optical cable strengthening core; especially optical fiber ribbon cable open stripping place easily twist, impaired, naked fibre can not get effective protection, can not adapt to the needs of optical fiber distributing equipment development.
Summary of the invention
The purpose of this utility model is to overcome the deficiencies in the prior art and defective, solve that stripping is fixed, opened to existing optical cable, the protective device capacity can not increase and decrease and optical cable stripping place is easily twisted, impaired technical matters opening.
In order to solve above technical matters, the technical solution adopted in the utility model is:
A kind of optical fiber ribbon cable that is used for optical fiber distributing equipment is driven the stripping protective device; it comprises the base plate of fixing optical cable and is connected by wire rod thread with base plate and is superimposed upon one or more U type optical fibre clips on the base plate that the many to naked fine protective casing draw-in groove of mutual correspondence are arranged on the U type optical fibre clip two sides.
Described naked fine protective casing draw-in groove all is complementary with the shape size of banded naked fine protective casing.
After adopting technique scheme, because the quantity of U type optical fibre clip can increase and decrease, the capacity that makes optical cable fix, open stripping, protective device can increase and decrease according to actual needs, the difference of the core number of energy flexible adaptation optical cable and the difference of strengthening core radical; In addition, because naked fine protective casing draw-in groove is all identical with the shape size of banded naked fibre, make shielded naked fibre open the difficult distortion of stripping place and impaired, thereby obtain safer, comprehensive, effectively protection reliably.

Embodiment
Describe embodiment of the present utility model in detail below in conjunction with accompanying drawing.
As Fig. 1; 2; optical fiber ribbon cable shown in 3 is driven the stripping protective device; comprise: the stainless steel base plate 1 that optical cable is fixing; stack is installed in the U type optical fibre clip 4 of base plate afterbody; the fixing strengthening core fixture 7 of optical cable strengthening core; and stainless protective cover 2; the U type optical fibre clip 4 that stacks up utilizes screw mandrel 5; hexagonal nut 6 is fixed on the base plate 1; optical cable strengthening core 16 utilizes short screw 3 to be clamped in the strengthening core fixture 7, and protective cover 2 can prevent that foreign object hinders naked finely 21, and the naked fine protective casing draw-in groove on the U type optical fibre clip two sides and the shape size of banded naked fibre all are complementary; promptly a naked fine protective casing draw-in groove just blocks a naked fibre with naked fine protective casing; on base plate 1, have fixed orifice 8,9,10; they are used for fixing U type optical fibre clip 4 respectively; strengthening core fixture 7 and protective cover 2; square hole 11 is used for the utility model is fixed on the optical cable fixed head 20, and card 12,13 is used for pricking larynx button 19 usefulness; two mounting holes 15 are arranged on the U type optical fibre clip 4, and have the draw-in groove 14 of six naked fine protective casings 22 of card.
As shown in Figure 4, optical cable 18 is opened after the stripping, with larynx button 19 optical cable metal armor layer 17 is fixed on the base plate 1, strengthening core 16 is inserted in the strengthening core fixture 7, with short screw 3 chuckings.Insert in the naked fine protective casing 22 naked fine 21; naked fine protective casing 26 is snapped in the draw-in groove 14 of U type optical fibre clip 4; the naked fine protective casing of the U type optical cable mounting board six roots of sensation; U type optical fibre clip 4 is superposeed by diagram; be fixed on the base plate 1 with screw mandrel 5, hexagonal nut 6 again, one reinstate larynx button 19 and be fixed on the optical cable fixed head 20 then.
