Abstract
The utility model provides an optical fiber head comprising a casing, a plurality of sub casings, a coating layer which coats the casing and a plurality of optical fibers installed in the sub casings. The sub casings are installed in the casing, and the optical fiber head is formed. The sub casings are made of a high performance carbon fiber reinforced coating material which is a new material with an excellent mechanical property. The sub casings made of the high performance carbon fiber reinforced coating material has the characteristics of toughness, corrosion resistance, light weight and electromagnetic shielding, and the weight of the optical fibers is reduced. The plurality of optical fibers are bundled, abrasion is easily generated between them, thus the surfaces of the optical fibers are damaged to influence the transmission performance of optical fibers, an employed effective measure for preventing the damage is coating a polymer coating layer on the surfaces of the optical fibers, and the microbending performance of the optical fibers is improved at the same time.
Description
Technical field
The utility model belongs to the optical fiber technology field, particularly a kind of optical fiber head that is applicable to the high power laser light transmission.
Background technology
At present, in fields such as medical treatment, materials processing, laser displayes, require the Output optical power of optical fiber head very high, traditional optical fiber head structure comprises fixed sleeving and simple optical fiber, fixed sleeving is conducive to optical fiber head structure is fixed on other devices, and simple optical fiber is inserted in the fixed sleeving and sticks with glue knot on every side and is fixed in the fixed sleeving.Optical fiber head generally will grind, PROCESS FOR TREATMENT such as polishing, if the inadequately meticulous meeting of grinding causes fiber end face the phenomenon that burr etc. influences flatness to occur, perhaps fiber end face has adhered to dust or cut appears in end face in the process of using, the capital causes the generation of scattering phenomenon, scattered light can heat optical cement, when being used for the high power laser light transmission, the heat build-up phenomenon will be very serious, the optical cement pollution fiber end face that will volatilize, when heat build-up arrives to a certain degree, being positioned near the optical cement in optical fiber head end will burn, and burn near the optical fiber head zone, the optical fiber head that burns out can only grind again and could use, and serious can only change optical fiber head.Utilize simple optical fiber output high-power laser, can only adopt no adhesive process, namely produce a groove in the end of optical fiber head.Expose in groove near making the end of simple optical fiber, but this structure is to the rigidity requirement height of optical fiber, otherwise the end of optical fiber will be crooked, and the output power of single laser instrument is also very limited in addition, and this has also greatly limited the power of transmission laser in the connected simple optical fiber.
Summary of the invention
The purpose of this utility model is, at the deficiency of existing above-mentioned existence, provides a kind of optical fiber head that is applicable to the high power laser light transmission.
The optical fiber head that the utility model provides is characterized in that, comprises sleeve pipe, a plurality of sub-sleeve pipe, is coated on the outer coat of sleeve pipe and is installed in multifiber in the described sub-sleeve pipe, and described sub-sleeve pipe is installed in the described sleeve pipe, forms optical fiber head.
In the described optical fiber head, described sub-sleeve pipe strengthens clad material by the good high-performance carbon fibre of heat conductivility to be made, and when to dispelling the heat when less demanding, sub-sleeve pipe can also be made by glass fibre.
In the described optical fiber head, described coat is one deck polymeric coating layer, mainly provides mechanical protection to optical fiber.
The beneficial effects of the utility model are: sub-sleeve pipe strengthens clad material by high-performance carbon fibre and makes, it is a kind of new material of mechanical property excellence that high-performance carbon fibre strengthens clad material, high-performance carbon fibre strengthen sub-sleeve pipe that clad material constitutes have toughness, corrosion-resistant, quality light, the characteristics of electromagnetic shielding characteristic, and alleviated the weight of optical fiber.Some such optical fiber boundlings are become a bundle, very easily produce wearing and tearing each other, cause optical fiber surface damage and influence the transmission performance of optical fiber, be coated with the high molecular coat of one deck at optical fiber surface exactly for preventing the effective measures that this damage is taked, the while is also improved the microbend performance of optical fiber.
Description of drawings
Fig. 1 is the structural representation of the utility model optical fiber head.
Embodiment
As shown in Figure 1, optical fiber head of the present utility model, comprise that described sub-sleeve pipe 2 is installed in the described sleeve pipe 1, forms optical fiber head from being followed successively by sleeve pipe 1, a plurality of sub-sleeve pipe 2 outside to inside, being coated on the outer coat 3 of described sleeve pipe 1 and being installed in multifiber 4 in the described sub-sleeve pipe 2.
In the described optical fiber head, described sub-sleeve pipe 2 is made by the good high-performance carbon fibre compound substance of heat conductivility, and when to dispelling the heat when less demanding, sub-sleeve pipe 2 can also be made by glass fibre.
In the described optical fiber head, described coat 3 is one deck polymeric coating layers, mainly provides mechanical protection to optical fiber.
High-performance carbon fibre strengthen sub-sleeve pipe 2 that clad material constitutes have toughness, corrosion-resistant, quality light, the characteristics of electromagnetic shielding characteristic, and alleviated the weight of optical fiber.Some such optical fiber 4 boundlings are become a bundle, very easily produce wearing and tearing each other, cause optical fiber surface damage and influence the transmission performance of optical fiber, be coated with the high molecular coat 3 of one deck at optical fiber surface exactly for preventing the effective measures that this damage is taked, the while is also improved the microbend performance of optical fiber.
Embodiment recited above only is that preferred implementation of the present utility model is described; be not that scope of the present utility model is limited; under the prerequisite that does not break away from the utility model design spirit; various distortion and improvement that the engineering technical personnel of this area make technical solutions of the utility model all should fall into the protection domain that claims of the present utility model are determined.
