Description
Technical field
The utility model relates to a kind of USB 3.0 type joints of optical fibre jointings, belongs to optical fiber electric and communication technical field.
Background technology
Along with the arriving of information age 21 century, Impact of Information Technology and changing people's mode of production and life style, becomes the important impetus amount of modern Economy Development.Communication has been penetrated into people's Working Life and socioeconomic every aspect.Under this overall background, faster, more convenient, more practical communications connector product is the developing direction of current communications connector product.
The joints of optical fibre compare with traditional electrical connector that to have anti-electromagnetic interference (EMI) good, and transfer efficiency is high, and the unique advantage of the little grade of volume, is widely used in fiber optic communication field.And the AOC joints of optical fibre and the existing joints of optical fibre are not both and can use with the supporting integration of existing integrated circuit, photoelectric conversion module integrated circuit is installed in connector and does not need use equipment separately to carry out opto-electronic conversion, saved data center, the spaces such as large-scale machine room, simultaneously can be compatible with the terminal device such as existing computer, thus market outlook widely had.In joints of optical fibre field, jointing is for the connection with optical fiber that grips of optical cable, existing jointing is subject to the restriction of structure, joint holding capacity and holding force are less, easy stress deformation, joint pulls when stressed can make optic fibre force, and this will affect the switching performance of optical fiber, even makes optical fiber impaired and affect its transmission performance.Therefore the environment for use requirement that, the existing joints of optical fibre are also difficult to meet the needs of frequent plug and pull.
Summary of the invention
Technical problem to be solved in the utility model is that the deficiency existing for above-mentioned prior art provides a kind of USB 3.0 type joints of optical fibre jointings, and it is not only simple in structure, be easy to assembling and use, and tensile property is strong, and reliability is high, and tolerance is strong.
The utility model is that the technical scheme that the problem of the above-mentioned proposition of solution adopts is: include tubular configured joint body and crimping tapered sleeve, tubular configured joint body front end arranges crimping seat, crimping seat and crimping tapered sleeve phase configuration, the rear end socket tail protective sleeve of tubular configured joint body.
Press such scheme, described tubular configured joint body rear end periphery is provided with stop lug or screw thread, and for being connected with tail protective sleeve, described crimping seat has larger external diameter and crimping endoporus, by crimping endoporus and crimping tapered sleeve phase configuration.
Press such scheme, described crimping tapered sleeve outer peripheral face is truncated cone, and front end arranges the shaft shoulder that diameter is larger, and crimping tapered sleeve is by outer peripheral face and the crimping endoporus phase configuration of truncated cone.
Press such scheme, the outer peripheral face coning angle of crimping tapered sleeve is 15～30 °.
Press such scheme, described tubular configured joint body and crimping tapered sleeve are made by metal material.
Press such scheme, the endoporus of described tail protective sleeve is divided into two sections, and leading portion aperture is large and be provided with Elastic buckle or screw thread, and with stop lug or the screw thread phase configuration of tubular configured joint body rear end, back segment aperture dwindles and the external diameter phase configuration that is connected optical cable.
Press such scheme, described tail protective sleeve is made of plastics.
The utility model penetrates tail protective sleeve and tubular configured joint body endoporus by optical cable while using, cable outer sheath termination is to crimping seat endoporus bottom, the metal strengthening core of optical cable and aramid yarn reserve a part and pass from the gap between crimping tapered sleeve and crimping seat from cable outer sheath termination, in cable, optical fiber passes from the endoporus of crimping tapered sleeve, by pneumatic striking mechanism, impact crimping tapered sleeve, crimping tapered sleeve is pressed into crimping seat endoporus, make both tight crimping, press nip is lived metal strengthening core and aramid yarn thus, reach firm grip and live the object that whole optical cable is avoided optic fibre force in cable.After crimping completes, tail protective sleeve is pushed to tubular configured joint body rear end and by buckle or screw thread, tail protective sleeve is closely connected with fittings body, due to tail protective sleeve back segment and the tight socket that is connected optical cable, optical cable and being connected further of joint are strengthened.
The beneficial effects of the utility model are: 1, by reinforcement side pressure in optical cable in fittings body, because crimping tapered sleeve wall pressure is large, therefore crimping is very tight, make that the utility model not only has that crimping is simple, connection reliability, to characteristics such as optical fiber are harmless, and tension compressive property is strong, the more severe environment for use of ability, guarantees the result of use steady in a long-term of jointing; 2, the utility model structure arranges advantages of simple, and volume is little, and intensity is high, easy to make, is easy to assembling and uses; 3, applied widely, be not only applicable to the joints of optical fibre, be also applicable to various other types connectors, tensile strength is high, is particularly useful for repeatedly plugging the connector that is simultaneously subject to pulling force larger.
