Abstract

The utility model relates to a hot melt type quick connector, including the SC inner core, the inside of SC inner core is equipped with ceramic lock pin and the tail cover of pegging graft, and the single mode overcoat is established to the left end grafting dustproof cap of ceramic lock pin, the outside cover of SC inner core together, the right -hand member fixed spring cover of SC inner core, and the inside of spring housing is equipped with the spring that supports by at SC inner core terminal surface, the long shell of right -hand member fixed length cylindric of spring housing, the right -hand member portion of the long shell of length cylindric passes through the threaded connection nut. The utility model discloses a hot melt type quick connector novel structure adopts the long shell of long cylindric to make the length of hot melt pipe adjust when the butt fusion, open denude fine tail optical fiber for the first time unsuccessful can going on division shell second time, but also the loss can be opened again greatly and is shelled the hot melt behind the optic fibre hot melt, has promoted greatly and has used successfully efficiency, sparingly the cost.

Description

Heat molten type quick connector

Technical field

This utility model relates to a kind of heat molten type quick connector.

Background technology

In optical communication network, it is often necessary to optical fiber is continued, the two ways that continued of optical fiber, one is cold joint mode, it is possible to be quickly connected with simple instrument, but the loss of optical fiber can be relatively larger; Another kind is hot melting way, adopts hot melting way to need special equipment to carry out welding, and the sheathed tempreature bulb in fusion point place, fibre loss is little. So typically now adopting hot melting way to carry out fibre junction. Need when carrying out fused fiber splice to adopt quick connector to carry out on heat sealing machine, and the shell of the quick connector of prior art is comparatively short, in use optical fiber generally can only stripping and hot melt once, stripping is unsuccessful or the unsuccessful waste leading to product of welding.

Utility model content

For solving above-mentioned technical problem, this utility model provides a kind of heat molten type quick connector.

Heat molten type quick connector of the present utility model, including SC inner core, the inside of described SC inner core is provided with the ceramic insertion core and tail sleeve that are plugged in together, the left end grafting dust cap of ceramic insertion core, the sheathed single mode overcoat in outside of SC inner core, the right-hand member of SC inner core fixes spring housing, and the inside of spring housing is provided with the spring being resisted against SC inner core end face, the right-hand member of spring housing fixes the long shell of long tubular, and the right part of the long shell of long tubular is threaded connection nut.

Heat molten type quick connector of the present utility model, described ceramic insertion core adopts press-connection machine to be pressed in tail sleeve.

Heat molten type quick connector of the present utility model, the left end head of described ceramic insertion core is plugged on inside the right-hand member of dust cap.

Compared with prior art the beneficial effects of the utility model are: heat molten type quick connector novel structure of the present utility model, the long shell of long tubular is adopted to make the length of tempreature bulb to regulate when welding, stripping optical fiber pigtail is unsuccessful for the first time can carry out second time stripping, and loss greatly can stripping hot melt again after optical fiber hot melt, it is greatly improved and uses successfully efficiency, save cost.

Detailed description of the invention

Below in conjunction with drawings and Examples, detailed description of the invention of the present utility model is described in further detail. Following example are used for illustrating this utility model, but are not limited to scope of the present utility model.

As shown in Figure 1-2, a kind of heat molten type quick connector, including SC inner core 1, the inside of described SC inner core 1 is provided with the ceramic insertion core 2 and tail sleeve 3 that are plugged in together, the right-hand member of outside sheathed single mode overcoat 5, the SC inner core 1 of left end grafting dust cap 4, the SC inner core 1 of ceramic insertion core 2 fixes spring housing 6, the inside of spring housing 6 is provided with the spring 7 being resisted against SC inner core 1 end face, and spring 7 ensures that ceramic insertion core 2 has certain stroke when plugging in adapter; The right-hand member of spring housing 6 fixes the long shell 8 of long tubular, and the right part of the long shell 8 of long tubular is threaded connection nut 9.

Heat molten type quick connector of the present utility model, described ceramic insertion core 2 adopts press-connection machine to be pressed in tail sleeve 3.

Heat molten type quick connector of the present utility model, the left end head of described ceramic insertion core 2 is plugged on inside the right-hand member of dust cap 4.

Heat molten type quick connector novel structure of the present utility model, adopts the long shell of long tubular to make the length of tempreature bulb to regulate when welding, therefore can lengthen heat molten type quick connector of the present utility model fiber lengths below, increases and is fused into effect rate. Stripping optical fiber pigtail is the unsuccessful second time stripping that can carry out for the first time, and after optical fiber hot melt loss greatly can stripping hot melt again, be greatly improved and use successfully efficiency, saving cost.

Heat molten type quick connector of the present utility model is when specifically used, this use new-type heat-melting type quick connector is taken out from outer package, single mode shell and the long shell of long tubular are taken off, the appropriate coat of optical fiber is peelled off with peeling plier, if stripping is unsuccessful can carry out second time stripping, suitable length is measured with cutter cutting optical fibre and with specialty measurer, being penetrated by heat-shrink tube wants on welding optic fibre, this utility model heat molten type quick connector is placed on heat sealing machine heat molten type connect soon in fixture, the heat sealing machine other end puts into the optical fiber of well cutting, start heat sealing machine and select automatic welding, cover dust cap, hear buzzer welding success, check welding numerical value, if splice loss, splice attenuation is excessive, again stripping, cutting optical fibre carries out welding, good for welding optical fiber is taken off with carrying fine device after welding success, protect pipe box in the place of welding hot melt, start pyrocondensation button, by the time buzzer thermoplastic is complete, take off the optical fiber that welding is good, welding completes. problems with is should be noted that: when 1, removing coat, to choose correct position when welding, dynamics is moderate, prevent optical fiber from cutting off, 2, cutting optical fibre time, horizontal positioned answered by optical fiber, ensure the smooth of facet, ready for welding, 3, welding complete after extract optical fiber time it is noted that lift mode, it is possible to first extract one end with hands, extracting the other end, it is prevented that optical fiber is disconnected fine from posetionof weld.

The above is only preferred implementation of the present utility model; should be understood that; for those skilled in the art; under the premise without departing from this utility model know-why; can also making some improvement and modification, these improve and modification also should be regarded as protection domain of the present utility model.
