Embodiment
Below in conjunction with accompanying drawing embodiment, the present invention is described in further detail.
As shown in Fig. 1 ~ Fig. 8, the dust-proof joints of optical fibre in the present embodiment and adapter, comprise the adapter sleeve 3 of Optical fiber plug 1, optical cable 2, connecting fiber plug 1 and optical cable 2, adaptor body 4.
Wherein, adaptor body 4 has the jack 41 suitable with Optical fiber plug 1, the end face of adaptor body 4 is provided with the connection boss 42 of annular, this connection boss 42 is positioned at the periphery of jack 41.
The periphery wall of adapter sleeve 3 has outer connecting thread, and the front end circumference of adapter sleeve 3 is convexly equipped with the shaft shoulder.
A dust guard is arranged with outside adapter sleeve 3.This dust guard comprises the dust cap 5 be socketed in outside adapter sleeve 3, is socketed in the outer and O-ring seal 6 be wrapped in dust cap 5 of adapter sleeve 3, the space of sealing circle 6 between dust cap 5 and the shaft shoulder.
Wherein, dust cap 5 flare, one end of the large mouth of dust cap 5 stretches out and is provided with the first connection perisporium 51, and this first connects perisporium 51 and be connected boss 42 adaptation and be tightly connected.In the present embodiment, first connects perisporium 51 has internal thread, connects boss 42 and has external thread, then dust cap 5 is threadedly connected to by the first connection perisporium 51 and connects on boss 42.Be provided with sealing gasket 9 to prevent from entering dust between the first connection perisporium 51 and adaptor body 4, optimize sealing effectiveness.
One end of dust cap 5 osculum stretches out and is provided with the female second connection perisporium 52 of a tool, and this second connection perisporium 52 is connected on adapter sleeve 3 by internal thread adaptation.
Adapter sleeve 3 is outer is also socketed with one for connecting the support ring 7 of O-ring seal 6, the front end face of this support ring 7 is connected with multiple pulley 71, described support ring 7 is butted on the shaft shoulder rear end face of adapter sleeve 3 by pulley 71, and support ring 7 can coordinate pulley 71 around adapter sleeve 3 axial-rotation.Support ring 7 rear end face is provided with a caulking groove 72, the interlocking of the fore-end of O-ring seal 6 in this caulking groove 72, then O-ring seal 6 around adapter sleeve 3 axial-rotation time, avoid the friction between the shaft shoulder by the pulley 71 on support ring 7.In the present embodiment support ring 7 front end face on be evenly provided with multiple pulley 71, the axis of each pulley 71 is all along the radial distribution of support ring 7.
Described O-ring seal 6 lateral surface is obliquely installed and seals to coordinate to contact with the inwall of described dust cap 5, and namely O-ring seal 6 is downward-sloping gradually on front end to the back-end direction, thus matches with the inclined end face of dust cap 5.
In order to strengthen the sealing effectiveness of dust cap 5, second connects perisporium 52 extends out setting near the front periphery radial direction of O-ring seal 6, thus and forms a slit 521 between adapter sleeve 3.
O-ring seal 6 connects the rear end circumference of perisporium 51 near first and expands settings, thus formation can be incorporated into expanding along 61 of slit 521 by close-fitting.
Go back sealing shroud outside adapter sleeve 3 to be connected to one and to be connected perisporium 52 with second and to offset the block 8 arranged, block 8 can stop between dust cap 5 and adapter sleeve 3 and enters dust, coordinates and O-ring seal 6 forms dual sealing functions, and dust-proof effect is better.
In order to prevent mispluging of Optical fiber plug 1 and adapter, coupling is provided with and detects contact respectively on Optical fiber plug 1 and in the jack 41 of adapter.Optical fiber plug 1 is provided with and this Optical fiber plug 1 detects the jumper switch and jumper cap array combination 100 that contact is connected.Adaptor body 4 is provided with the jumper switch and jumper cap array combination 100 that are connected with check point on this adapter.Jumper switch and jumper cap array combination 100 are covered with protecting cover 300, thus available protecting jumper switch and jumper cap array combination 100.Adaptor body 4 is also provided with the contact be connected by testing circuit with check point on adaptor body 4 and detects lamp 200, wherein testing circuit can select custom circuit of the prior art.In the present embodiment, contact detection lamp 200 comprises two, and one is red colored lamp, and another is green light, and when Optical fiber plug 1 and adapter mate correct, green light is lighted, and when Optical fiber plug 1 and adapter do not mate, then red colored lamp is lighted.
In use, when Optical fiber plug 1 is inserted into after in the adaptor body 4 of coupling, under the effect of the jumper switch be separately positioned on Optical fiber plug 1 and adapter and jumper cap array combination 100, respective check point coupling connects, the testing circuit conducting be connected with green light, now, green contact is detected lamp 200 and is lighted display coupling correctly.When Optical fiber plug 1 is inserted in unmatched adaptor body 4, correspondingly, the testing circuit conducting be connected with red colored lamp, red contact is detected lamp 200 and is lighted display matching error.So can remind the match condition of Optical fiber plug 1 and adapter, prevent mispluging of Optical fiber plug 1 and adapter.
These dust-proof joints of optical fibre and adapter are in use, the sealing shroud rabbeted cooperation and support ring 7 are set in outside adapter sleeve 3, then dust cap 5 rotary sleeve is connected on outside adapter sleeve 3, because dust cap 5 is in horn-like, in the process that dust cap 5 rotates forward, the space that O-ring seal 6 is placed in dust cap 5 diminishes gradually, then dust cap 5 is to applying the centripetal force of inclination, and be with dynamic seal ring 6 around adapter sleeve 3 axial rotation, under the effect of support ring 7 top sheave 71, O-ring seal 6 can slide and easily without the need to overcoming the friction between the shaft shoulder of adapter sleeve 3, then dust cap 5 can rotate as much as possible forward and be pressed on O-ring seal 6, along with the continuous increase of dust cap 5 pairs of O-ring seal 6 pressure, expanding of O-ring seal 6 rear end is clamp-oned in the slit 521 of the second connection perisporium 52 along 61, then can effectively prevent dust from entering from the space between adapter sleeve 3 and dust cap 5, simultaneously under the effect of block 8, sealing effectiveness is better, can prevent from acting on pressure on dust cap 5 excessive simultaneously and the phenomenon of skidding occurs.When dust cap 5 fixes on adapter sleeve 3, first of dust cap 5 front end connects perisporium 51 and is just screwed on the connection boss 42 of adaptor body 4, prevents dust to enter into dust cap 5 from dust cap 5 big opening end, effectively prevent the pollution to jack 41.
