Abstract
The utility model discloses an optical fibre connector end on structure with high universality, which comprises a pressing sleeve, a hexagonal gland nut, a support frame and a heat shrinkage bush, wherein the support frame is provided with a stepped hole; a thread is arranged in the stepped hole; the hexagonal gland nut is matched with the support frame through threaded connection; the pressing sleeve is arranged in the stepped hole of the support frame; the hexagonal gland nut is mutually extruded with the zigzag conical surface of the pressing sleeve through threaded screwing so as to fix an optical cable enhancer (generally aromatic polyamide yarn); one end of the heat shrinkage bush is fixed on a hexagonal cylindrical surface; and the other end of the heat shrinkage bush is fixed on an optical cable. The utility model has high end on reliability and a simple structure, is convenient to disassemble and assemble and is suitable for environment resistance field communication networks.
Description
Technical field
The utility model relates to joints of optical fibre termination technology, relates in particular to a kind of various bad working environment that are applicable to, and can keep the joints of optical fibre end on structure of better communication efficiency.
Background technology
Optical fiber telecommunications system more and more is subjected to research staff's favor with very strong anti-electromagnetic interference capability, good signal transmission quality, is widely used in commercialization or the military communications equipment.The extensive application of optical fiber telecommunications system makes being connected between optical fiber and the optical fiber seem more frequent, and the joints of optical fibre use in a large number.And the most reliability of the end on structure of the joints of optical fibre is not high and be non-dismountable, safeguards very inconvenience.The joints of optical fibre mainly realize that by spring force optical fiber docks with the physics of optical fiber, and as if the stressed end play that is prone between the fiber end face of joints of optical fibre afterbody then of access node structure for no reason, the insertion loss of light will increase.At present, the end on structure of the joints of optical fibre mostly designs according to separately design feature, suddenly lacks the end on structure can be general, easy to maintenance, that reliability is high.
The utility model content
The purpose of this utility model provides a kind of convenient disassembly, favorable sealing property, the joints of optical fibre end on structure that versatility is good.
To achieve these goals, the utility model by the following technical solutions: described versatility joints of optical fibre end on structure is threaded into the zigzag conical surface of realizing with gland by six side's gland nuts and is meshing with each other with fixing optical cable reinforcement; Bracing frame is provided with shoulder hole, is provided with screw thread in the hole, and gland places in the shoulder hole of bracing frame, and six side's gland nuts match with bracing frame by being threaded, and heat-shrinkable T bush one end is fixed on the hexagonal prism face, and the other end is fixed on the optical cable.
Described six side's gland nuts are meshing with each other with fixing optical cable reinforcement by being threaded into the zigzag conical surface of realizing with gland.
Described six side's gland nuts are provided with the zigzag conical surface and hexagonal prism face.
Described gland is provided with the zigzag conical surface, and it is positioned at the shoulder hole of bracing frame.
The joints of optical fibre end on structure of the versatility that the utility model provides, the advantage that compared with prior art has: use six side's gland nuts to be threaded into, make it on gland fixedly optical cable reinforcement of zigzag conical surface mutual extrusion; The utility model structure is more reliable, and is easy to maintenance, prevented because of the stressed axial displacement that produces between fiber end face of joints of optical fibre afterbody.

Fig. 1 is the structural representation of the joints of optical fibre end on structure of the utility model versatility;
Fig. 2 is the structural representation of the utility model gland;
Fig. 3 is the structural representation of the utility model six side's gland nuts.
Embodiment
Further specify the technical scheme of the utility model embodiment below in conjunction with the drawings and specific embodiments.
The joints of optical fibre end on structure of the versatility in shown in Figure 1 is made up of bracing frame 7, gland 2, six side's gland nuts 5 and heat-shrinkable T bush 6, bracing frame 7 is provided with shoulder hole, be provided with screw thread in the hole, gland 2 places in the shoulder hole of bracing frame 7, six side's gland nuts 5 are threaded with bracing frame 7, optical cable reinforcement 4 places the zigzag conical surface of gland 2 and six side's gland nuts 5, heat-shrinkable T bush 6 one ends are fixed on six side's gland nuts 5, the other end is fixed on the optical cable 3, and light transmitting fiber 1 is by in the shoulder hole of bracing frame 7.
In shown in Fig. 1-3, gland 2 is provided with the zigzag conical surface 8 and fiber channel 9, six side's gland nuts 5 are provided with the zigzag conical surface 12, screw thread 10 and hexagonal prism face 11, by rotation hexagonal prism face 11 six side's gland nuts 5 are threaded in the bracing frame 7, the zigzag conical surface 8 and the zigzag conical surface 12 mutual extrusion are with fixing optical cable reinforcement 4.
In sum; it below only is preferred embodiment of the present utility model; be not to be used to limit protection domain of the present utility model; therefore; all any modifications of within spirit of the present utility model and principle, being done, be equal to replacement, improvement etc., all should be included within the protection domain of the present utility model.
Claims (4)
1. the joints of optical fibre end on structure of a versatility is characterized in that:
Described joints of optical fibre end on structure, by six side's gland nuts be threaded into realize with the zigzag conical surface mutual extrusion of gland with fixing optical cable reinforcement; Bracing frame is provided with shoulder hole, is provided with screw thread in the hole, and gland is fixed in the shoulder hole of bracing frame, and six side's gland nuts match with bracing frame by being threaded.
2. joints of optical fibre end on structure according to claim 1 is characterized in that, described six side's gland nuts are meshing with each other with fixing optical cable reinforcement by being threaded into the zigzag conical surface of realizing with gland.
