Description
Technical field
The present invention relates to a kind of optical cable strengthening core and fix unit clamp.
Background technology
Optical cable is generally made up of oversheath, optical fiber (8), strengthening core (7) etc., and optical cable strengthening core is divided into metal and nonmetal bi-material.Article one, longer lightguide cable link is formed by connecting by multistage optical cable.Cable outer sheath in ordinary optical cable, optical fiber can not hold to be adopted extruding and stretches, conventional optical cable (metal optical cable and non-metallic optical fiber cables) is the pulling force bearing optical cable with the strengthening core of centre (7), during normal operation, external pull should act on optical cable strengthening core.When optical cable enters rack or connector box, need fixing optical cable strengthening core.The fixing means that current end of cable strengthening core is conventional presets strengthening core set bolt at optical fiber cable distribution frame, equipment rack or cable splice closure place, optical cable strengthening core (7) bolt crimping, as shown in Figure 1.Optical fiber (8) in optical cable walk around optical cable strengthening core set bolt laggard enter optical fiber connector area.There is following problem in the fixed form of this bolt crimping:
1. bolt rotates top pressure optical cable strengthening core, has caused the damage of strengthening core at installation phase.
2. compression joint area is very little, causes stress to concentrate, and can not make full use of the physical strength of optical cable strengthening core.
3. after optical cable strengthening core being crimped, when the twisting of optical cable low-angle or aerial optical cable connector box and optical cable not the swing same period can produce torsion, easily cause strengthening core cracked, rupture.
4. be in operation, temperature variation, vibration cause bolt looseness, cause strengthening core slippage.
Optical cable strengthening core unit clamp of the present invention, can solve the problem preferably, can be widely used in metal optical cable, non-metallic optical fiber cables at the end winding support of various occasion (two ends rack, intermediate joint box, fiber cable cross connection box etc.).
Summary of the invention
The object of the present invention is to provide optical cable strengthening core to fix unit clamp, its structure is simple, can solve conventional fixation means Problems existing preferably, and it is simple to operate, safe and reliable.
The present invention reaches above-mentioned object, adopts following technical scheme:
Optical cable strengthening core of the present invention fixes unit clamp, adopts sliding wedge crimping mode, strengthens compression joint area, increase locking device.Cable Core of the present invention fixes that unit clamp comprises fixture overcoat (1), sliding wedge (2), screws lid (3), plain cushion (4), film shape bullet circle (5), described optical cable strengthening core fixes the fixture overcoat (1) of unit clamp for cylindrical, a wedged hole is had in centre, sliding wedge (2) is loaded in the wedged hole of fixture overcoat (1), fixture overcoat (1) tail end has external thread, screws lid (3) and is arranged on fixture overcoat (1) by screw thread.Optical cable strengthening core penetrates in the circular trough in unit clamp in the middle of two pieces of sliding wedges, and sliding wedge (2) compresses the strengthening core of optical cable in the wedged hole slides forwards of fixture overcoat (1).Lid (3) promotion sliding wedge (2) forward slip is screwed, clamping optical cable strengthening core by being screwed into.Screw between lid (3) and sliding wedge (2) and be lined with plain cushion (4) and film shape bullet pad (5), prevent from screwing the loosening of lid and sliding wedge.Fixture overcoat (2) outer wall there is the circular hole that 2 symmetrical, for the clamping position of specific purpose tool.
Optical cable strengthening core of the present invention is fixed unit clamp and can be reused, the order of dismounting is contrary with order during assembling: first screw off to screw and cover (3), take off plain cushion (4) and film shape bullet pad (5), exit sliding wedge (2), pull-out optical cable strengthening core, completes the dismounting that Cable Core fixes unit clamp and optical cable.
Beneficial effect of the present invention is: the invention provides a kind of optical cable strengthening core and fix unit clamp, and its structure is simple, can prevent optical cable strengthening core from damaging, ruptures and loosen, can reuse, and it be simple to operate, safe and reliable.

Embodiment
Embodiment 1
As shown in Figure 2, the present embodiment provides a kind of optical cable strengthening core and fixes unit clamp, comprise fixture overcoat (1), sliding wedge (2), screw lid (3), plain cushion (4), film shape bullet circle (5), described optical cable strengthening core fixes the fixture overcoat (1) of unit clamp for cylindrical, centre has a wedged hole, sliding wedge (2) is loaded in the wedged hole of fixture overcoat (1), fixture overcoat (1) tail end has external thread, screws lid (3) and is arranged on fixture overcoat (1) by screw thread.
As shown in Figure 2 and Figure 9, the strengthening core (7) of optical cable (6) penetrates in the circular trough in unit clamp in the middle of two pieces of sliding wedges, and sliding wedge (2) connects optical cable strengthening core (7) in the wedged hole slides forwards clamping of fixture overcoat (1).Screwing lid (3) promotion sliding wedge (2) forward slip by being screwed into, compressing optical cable strengthening core.Screw between lid (3) and sliding wedge (2) and be lined with plain cushion (4) and film shape bullet pad (5), prevent from screwing lid, the loosening of dynamic voussoir, the optical fiber (8) in optical cable walk around Cable Core fix special fixture laggard enter optical fiber connector area.
