Specific embodiment
The present invention is described in further detail below in conjunction with accompanying drawing embodiment.
As shown in Fig. 1～Fig. 8, the dustproof construction of the joints of optical fibre and adapter in the present embodiment, including Optical fiber plug
1st, adapter sleeve 3, the adaptor body 4 of optical cable 2, connection Optical fiber plug 1 and optical cable 2.
Wherein, set on the end face of adaptor body 4 with the jack 41 being adapted with Optical fiber plug 1 on adaptor body 4
The connection boss 42 of annular is equipped with, the connection boss 42 is located at the periphery of jack 41.
There is on the periphery wall of adapter sleeve 3 outer connection screw thread, the front end of adapter sleeve 3 is circumferentially convexly equipped with the shaft shoulder.
A dust guard is arranged with outside adapter sleeve 3.The dust guard includes the dust cap 5 being socketed in outside adapter sleeve 3, socket
Sealing ring 6 that is outer in adapter sleeve 3 and being wrapped in dust cap 5, the sealing ring 6 are located at the space between dust cap 5 and the shaft shoulder.
Wherein, 5 flare of dust cap, one end of 5 big mouth of dust cap stretch out and are provided with the first connection perisporium 51, should
First connection perisporium 51 is tightly connected with the adaptation of boss 42 is connected.In the present embodiment, the first connection perisporium 51 has female thread, even
Connect boss 42 and there is external screw thread, then dust cap 5 is threadedly connected on connection boss 42 by the first connection perisporium 51.First connection
Sealing gasket 9 is provided between perisporium 51 and adaptor body 4 to prevent from entering dust, optimizes sealing effectiveness.
One end of 5 osculum of dust cap stretches out and is provided with the female second connection perisporium 52 of a tool, second company
Connect perisporium 52 to be connected on adapter sleeve 3 by female thread adaptation.
Adapter sleeve 3 is outer to be also socketed with one for connecting the support ring 7 of sealing ring 6, and connection on the front end face of the support ring 7 sets
Multiple pulleys 71 are equipped with, the 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 is around 3 axial-rotation of adapter sleeve.A caulking groove 72 is provided with 7 rear end face of support ring, and the fore-end interlocking of sealing ring 6 exists
In the caulking groove 72, then when sealing ring 6 is around 3 axial-rotation of adapter sleeve, by the pulley 71 in support ring 7 avoid with the shaft shoulder it
Between friction.Multiple pulleys 71, the equal edge of axis of each pulley 71 is evenly arranged with the present embodiment on the front end face of support ring 7
The radial distribution of support ring 7.
6 lateral surface of the sealing ring is obliquely installed to be coordinated with the inwall with the dust cap 5 and contacts sealing, i.e. sealing ring 6
Inclined from front end backward extreme direction gradually downward, so as to match with the inclined end face of dust cap 5.
In order to strengthen the sealing effectiveness of dust cap 5, the second connection perisporium 52 is radially extended out near the front periphery of sealing ring 6
Arrange, so as to form a slit 521 between adapter sleeve 3.
Sealing ring 6 near first connection perisporium 51 rear end circumferentially expand setting, so as to formed can close-fitting be incorporated into slit
521 expand along 61.
The outer also sealing of adapter sleeve 3 is socketed with one and is connected perisporium 52 with second and offsets the block 8 of setting, and block 8 can be prevented
Dust being entered between dust cap 5 and adapter sleeve 3, being coordinated and sealing ring 6 is formed dual sealing functions, dust-proof effect is more preferable.
In order to prevent mispluging for Optical fiber plug 1 and adapter, matched on Optical fiber plug 1 and in the jack 41 of adapter respectively
It is provided with detection contact.The jumper switch and jump for being provided with Optical fiber plug 1 and detecting on the Optical fiber plug 1 that contact is connected
Line cap array combination 100.The jumper switch and jumper cap being connected with test point on the adapter is provided with adaptor body 4
Array combination 100.Protecting cover 300 is covered with jumper switch and jumper cap array combination 100, so as to effective protection jumper switch and
Jumper cap array combination 100.It is additionally provided with adaptor body 4 and is connected by detecting circuit with test point on adaptor body 4
The contact detection lamp 200 for connecing, wherein detects that circuit can select custom circuit of the prior art.Contact detection in the present embodiment
Lamp 200 includes two, and one is red colored lamp, and another is green light, when Optical fiber plug 1 and correct adapter matching, green
Lamp is lighted, and when Optical fiber plug 1 and adapter are mismatched, then red colored lamp is lighted.
When in use, after Optical fiber plug 1 is inserted in the adaptor body 4 of matching, it is being separately positioned on Optical fiber plug 1
In the presence of the jumper switch on adapter and jumper cap array combination 100, each detection Point matching connection, with green light phase
The detection circuit turn-on of connection, now, the contact detection lamp 200 of green lights display matching correctly.When Optical fiber plug 1 is inserted into
When in unmatched adaptor body 4, correspondingly, the detection circuit turn-on being connected with red colored lamp, red contact detection lamp
200 light display matching error.The match condition of Optical fiber plug 1 and adapter can be so reminded, Optical fiber plug 1 is prevented and is fitted
Orchestration is mispluged.
The dustproof construction of the joints of optical fibre and adapter when in use, will coordinate the sealing shroud and support ring 7 rabbeted
It is set in outside adapter sleeve 3, then the rotation of dust cap 5 is socketed in outside adapter sleeve 3, as dust cap 5 is in horn-like, in dust cap
5 forward rotate during, the space that sealing ring 6 is placed in dust cap 5 tapers into, then dust cap 5 to apply it is inclined to
Mental and physical efforts, and band dynamic seal ring 6, around 3 axial rotation of adapter sleeve, in the presence of 7 top sheave 71 of support ring, sealing ring 6 can be light
Slip and need not overcome and the friction between the shaft shoulder of adapter sleeve 3, then dust cap 5 can rotate forward as far as possible and compress
On sealing ring 6, with continuous increase of the dust cap 5 to 6 pressure of sealing ring, expanding for 6 rear end of sealing ring clamp-ons second along 61
In the slit 521 of connection perisporium 52, then can effectively prevent space of the dust between adapter sleeve 3 and dust cap 5 from entering, while in lid
In the presence of cap 8, sealing effectiveness more preferably, while be prevented from acting on pressure on dust cap 5 is excessive and showing of occurring to skid
As.When dust cap 5 is fixed on adapter sleeve 3, the first connection perisporium 51 of 5 front end of dust cap is screwed in adapter sheet just
On the connection boss 42 of body 4, it is therefore prevented that dust is entered in dust cap 5 from 5 big opening end of dust cap, effectively prevent to jack 41
Pollution.
