Description
Technical field
The utility model relates to optical protective structure.
Background technology
Optical fiber is fibre-optic writing a Chinese character in simplified form, and is a kind of fiber be made up of glass or plastics, can be used as light conduction instrument.Transmission principle is " total reflection of light ", and in daily life, because light is more much lower in the loss of electric wire conduction than electricity in fibre-optic conduction loss, optical fiber is used as the information transmission of long distance.
For preventing the damage of optical fiber, be generally equipped with hot melt protective jacket and cap bag in the outside of optical fiber, existing hot melt protective jacket and cap bag are generally fastened, this spline structure is insecure, easily lose accessory when receiving impact, and need auxiliary instrument when assembling, assembling is inconvenience comparatively.
Utility model content
For the deficiencies in the prior art, the purpose of this utility model is intended to provide a kind of optical protective structure, its sound construction, and assembling more for convenience.
For achieving the above object, the utility model adopts following technical scheme:
Optical protective structure, comprising:
Hot melt protective jacket, this hot melt protective jacket is provided with the first mounting hole for receiving optical fiber, and this first mounting hole extends along the length direction of this hot melt protective jacket;
Cap bag, this cap bag is installed on one end of hot melt protective jacket and is threaded with this hot melt protective jacket, and this cap bag is provided with away from one end of hot melt protective jacket and for being plugged in the joints of optical fibre plugs end, and this cap bag is provided with locating flange near one end of hot melt protective jacket;
Sleeve, is set in the outside of hot melt protective jacket, the medial surface of this sleeve offers the air channel that the length direction along this sleeve extends.
The outside of this locating flange is taper surface, and this taper surface narrows from away from the side plugging end gradually near the side plugging end.
The end outside that plugs of this cap bag is provided with chamfering.
The beneficial effects of the utility model are:
Compared to prior art, cap bag of the present utility model is threaded with hot melt protective jacket, such sound construction, not easily accessory is lost when receiving impact, only cap bag and hot melt protective jacket need be tightened by hand when assembling, without the need to auxiliary instrument, assembling more for convenience, the outside of hot melt protective jacket is set with sleeve, such arrival double protection, strengthen protected effect, and, the medial surface of sleeve offers the air channel that the length direction along this sleeve extends, the gas be extruded between sleeve and hot melt protective jacket is avoided to overstock in gap, sleeve and hot melt protective jacket fully can be compressed like this, the steadiness of further raising structure, when cap bag is plugged on the joints of optical fibre, locating flange can with the joints of optical fibre screens face coordinate, play positioning action, facilitate the installation of cap bag and the joints of optical fibre.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model;
Fig. 2 is the structural representation of hot melt protective jacket and sleeve in the utility model;
Wherein: 10, hot melt protective jacket; 11, the first mounting hole; 20, cap bag; 21, end is plugged; 211, chamfering; 22, locating flange; 23, the second mounting hole; 30, sleeve; 31, air channel.
Embodiment
Below, by reference to the accompanying drawings and embodiment, the utility model is described further:
As depicted in figs. 1 and 2, optical protective structure of the present utility model, comprises hot melt protective jacket 10, cap bag 20 and sleeve 30.This hot melt protective jacket 10 is provided with the first mounting hole 11 for receiving optical fiber, and this first mounting hole 11 extends along the length direction of this hot melt protective jacket 10; This cap bag 20 is installed on one end of hot melt protective jacket 10 and is threaded with this hot melt protective jacket 10, this cap bag 20 is provided with away from one end of hot melt protective jacket 10 and for being plugged in the joints of optical fibre plugs end 21, and this cap bag 20 is provided with locating flange 22 near one end of hot melt protective jacket 10; Sleeve 30 is set in the outside of hot melt protective jacket 10, the medial surface of this sleeve 30 offers the air channel 31 that the length direction along this sleeve 30 extends.
Cap bag 20 of the present utility model is threaded with hot melt protective jacket 10, such sound construction, not easily accessory is lost when receiving impact, only need tighten manual to cap bag 20 and hot melt protective jacket 10 when assembling, without the need to auxiliary instrument, assembling more for convenience, the outside of hot melt protective jacket 10 is set with sleeve 30, such arrival double protection, strengthen protected effect, and, the medial surface of sleeve 30 offers the air channel 31 that the length direction along this sleeve 30 extends, the gas be extruded between sleeve 30 and hot melt protective jacket 10 is avoided to overstock in gap, sleeve 30 and hot melt protective jacket 10 fully can be compressed like this, the steadiness of further raising structure, when cap bag 20 is plugged on the joints of optical fibre, locating flange 22 can with the joints of optical fibre screens face coordinate, play positioning action, facilitate the installation of cap bag 20 and the joints of optical fibre.
Further, the outside of this locating flange 22 is taper surface, and this taper surface narrows from away from the side plugging end 21 gradually near the side plugging end 21, like this can with the joints of optical fibre screens face location fit better.
Further, plugging outside end 21 of this cap bag 20 is provided with chamfering 211, is convenient to plug-in mounting.
Further, this cap bag 20 offers the second mounting hole 23 passed for optical fiber.
To one skilled in the art, according to technical scheme described above and design, other various corresponding change and deformation can be made, and all these change and deformation all should belong within the protection domain of the utility model claim.
