Abstract
The utility model discloses an optical fiber attenuator with an attenuation gasket. The optical fiber attenuator with the attenuation gasket comprises a shell in which an inner core assembly is arranged, a hollow cylinder is arranged in the inner core assembly, and a ferrule sleeve is arranged in the hollow cylinder; the attenuation gasket is sleeved on the outside of the ferrule sleeve, the inner core assembly comprises a first half inner core and a second half inner core, and a fastening groove positioning structure is arranged between the combining ends of the first and second half inner cores. The advantage of the utility model is that the positioning is more accurate and reliable by employing the fastening groove positioning structure between the first and second half inner cores.
Description
Technical field
The utility model relates to a kind of fibre optic attenuator, relates in particular to a kind of fibre optic attenuator with the decay pad.
Background technology
Fibre optic attenuator is widely used in the optical fiber communication as fiber optic passive device.In assembling optical fiber communication system process, the connection of telecommunication optical fiber for ease need be used the telecommunication optical fiber connector.The end of telecommunication optical fiber connector is provided with preceding lock pin, in the preceding lock pin telecommunication optical fiber is installed, and in order two telecommunication optical fibers between the telecommunication optical fiber connector to be connected and to be made the fiber-optic signal decay, need use fibre optic attenuator.Fibre optic attenuator comprises a plastic casing, is provided with inner core in the plastic casing, and inner core is provided with the lock pin sleeve, and the lock pin sleeve is used to insert the preceding lock pin of telecommunication optical fiber connector.Above-mentioned plastic casing all is made up of the identical parts of two-part structure with inner core.Existing fibre optic attenuator packaging technology is following: the pad of will decaying earlier is enclosed within on the lock pin sleeve, and the lock pin sleeve inserts in the right cylinder hollow of inner core, again two outer casing members is used ultrasonic soldering.Therefore the production and assembly technology of existing telecommunication optical fiber adapter is comparatively complicated.
Summary of the invention
The utility model technical matters to be solved provides a kind of fibre optic attenuator of band easy to assembly decay pad.
The utility model solves the problems of the technologies described above the technical scheme that is adopted: a kind of fibre optic attenuator with the decay pad; Comprise housing; Be provided with interior core assembly in the described housing; Be provided with hollow circular cylinder in the core assembly in described, be provided with the lock pin sleeve in the described hollow circular cylinder, the lock pin bush outer sleeve is provided with the decay pad; Core assembly comprises the first half inner cores and the second half inner cores in described, is provided with the draw-in groove location structure between the binding end of the binding end of described the first half inner cores and the second half inner cores.
The draw-in groove location structure comprises first locating piece, first locating slot, second locating piece and second locating slot is set; Described first locating piece is arranged on the A side of the first half inner core binding ends; Described first locating slot is arranged on the B side of the first half inner core binding ends; Described second locating piece is arranged on the B side of the second half inner core binding ends; Described second locating slot is arranged on the A side of the second half inner core binding ends, and described first locating piece cooperates with described second locating slot, and described first locating slot cooperates with described second locating piece.
Described housing comprises the first half housings and the second half housings, has the connectivity port respectively on described the first half housings and the second half housings, and described connectivity port is provided with dust cap.
Described housing is outside equipped with the fixedly jump ring of usefulness.
Compared with prior art, the utility model has the advantages that between the first half inner cores and the second half inner cores and adopt the draw-in groove location structure that it is more accurately firm to locate.
Can reach different pad values through the decay pad of selecting different-thickness.
Dust cap can effectively completely cut off and extraneous contacting, and prevents that dust from getting into.
