Embodiment of the present invention mainly comprise fiber optics connected with outer casing 10, casing cover element 20, fixed clamp device 30 for connecting the mechanical connector of fiber optics.
Fiber optics connected with outer casing 10 comprises square and laterally forms, and inserts between the 11He insertion section, insertion section 11 of optical cable 40 the fiber optics connecting portion 12 being integrated with insertion section 11.
On insertion section 11, there is patchhole 11a, in patchhole 11a, can insert along fiber optics connected with outer casing direction, the optical cable 40 inserting in central authorities, this is the core that fiber optics mechanical connector 1 entirety forms.
As shown in Figures 1 and 2, the xsect of insertion section 11 is square, be connected in the scope of casing cover element 20 (aftermentioned) on fiber optics connected with outer casing 10 square cross-sectional shape on insertion section 11 and complete connection, thereby form mechanical connector 1 as shown in Figure 1.
The shape of cross section of above-mentioned insertion section 11 can be square as depicted in figs. 1 and 2, can be also the shape such as rectangle or circle.
The height of the fiber optics connecting portion 12 forming between two insertion sections 11 at two ends will be lower than the level of insertion section 11, and sink to downside, lustrous fibre link slot 12a is gone back in inside simultaneously, fiber optics link slot 12a is " v " shape, the fiber optics 41 that is used for two optical cables 40 of the central part insertion that is connected to insertion section 11 is in fact axle core and the retaining part that encases axle core.
Further, on the dual-side edge of fiber optics connecting portion 12, have transversely arranged multiple lug link slots 13, lug link slot 13 connects with the lug 23 that is connected on casing cover element 20 described later.
On fiber optics connected with outer casing 10 and below, insertion section 11 above and below insertion section 11 and fiber optics connecting portion 12, have respectively horizontal formation and for being connected and fixed the clamper link slot 14,24 that clamps device 30.
The length of casing cover element 20 is consistent with the length of fiber optics connecting portion 12, is connected, and covers fiber optics connecting portion 12 with fiber optics connected with outer casing 10.The bottom surface dual-side of casing cover element 20 is along forming the multiple connection lugs 23 that protrude downwards simultaneously.
At this, connect lug 23 with in the time that casing cover element 20 is connected with fiber optics connected with outer casing 10, the lug link slot 13 of fiber optics connecting portion 12 connects, thereby prevents the left and right sides slippage of casing cover element 20.
On casing cover element 20, with under the state being connected at fiber optics connected with outer casing 10, on fiber optics connected with outer casing 10, form clamper link slot 14,24 and the clamper link slot 14,24 being adjacent.On the bottom surface of casing cover element 20, form corresponding with fiber optics link slot 12a, and the fiber optics that pressurizes of fiber optics 41 in the fiber optics link slot 12a protuberance 21 that pressurizes.Above-mentioned fiber optics pressurization protuberance 21 is to the central hub pressurization of fiber optics 41, and pressurization length is more than 6 millimeters.
Fixed clamp device 30 is made up of the first fixed clamp device and the second fixed clamp device, and simultaneously fixed clamp device 30 has vertical plane 31, extends out from vertical plane 31, corresponding surface level 32 mutually up and down, fixed clamp device 30 be "
" shape.
Further, fixed clamp device 30 is connected to the side of fiber optics connected with outer casing 10 and casing cover element 20, its upper and lower two corresponding surface levels 32 be close to fiber optics connected with outer casing 10 and casing cover element 20 above and below, there is pressurization lug 33 inner side of surface level 32, pressurization lug 33 and clamper link slot 14,24 connect, fixed housing cap member 20, and to its pressurization.
On the bottom surface of the shell connecting portion 12 of fiber optics connected with outer casing 10 and the corresponding casing cover element 20 of shell connecting portion 12, form the first guide groove 15 and the second guide groove 22.
The first guide groove 15 front ends are towards fiber optics link slot 12a, the tapered horizontal formation in both sides in fiber optics connecting portion 12, and be positioned at the front of patchhole 11a.Safe guidance fiber optics 41 enters fiber optics link slot 12a from the front of patchhole 11a by patchhole 11a.
The second guide groove 22 laterally forms in the both sides of fiber optics pressurization protuberance 21, and safe guidance fiber optics 41 enters fiber optics link slot 12a together with the first guide groove 15; Meanwhile, casing cover element 20 is in the time being connected with fiber optics connected with outer casing 10, corresponding with the upside of the first guide groove 15.
Next be described in detail with regard to the fiber optics connection procedure for the mechanical connector that connects fiber optics of embodiment of the present invention.
First, casing cover element 20 is connected with fiber optics connected with outer casing 10, and the first guide groove 15 in upper and lower corresponding state, inserts optical cable 40 by patchhole 11a with the second guide groove 22, and the inner side of fiber optics 41 being inserted to fiber optics connecting portion 12.
Now, the fiber optics 41 of insertion is introduced the inner side of fiber optics link slot 12a safely because of the first guide groove 15 and the second guide groove 22, and within being fixed on fiber optics link slot 12a.
That is to say, in the time that fiber optics 41 enters, even if departing from center, the line end of fiber optics 41 enters, before entering fiber optics link slot 12a, because the first guide groove 15 and the second guide groove 22 are guided to center again, thereby make fiber optics 41 can enter fiber optics link slot 12a safety and precise.
As mentioned above, in fiber optics 41 is connected fiber optics link slot 12a after, the first fixed clamp device and the second fixed clamp device are connected to the side of fiber optics connected with outer casing 10 and casing cover element 20.
Further, the end of upper lower horizontal plane of fixed clamp device 30 and the side end of fiber optics connected with outer casing 10 and casing cover element 20 corresponding after, stationary gripping part 30 pushes towards fiber optics connected with outer casing 10 and casing cover element 20 external force, and is connected with the periphery of fiber optics connected with outer casing 10 and casing cover element 20.
Now, 33 of pressurization lugs that form on the surface level of fixed clamp device 30 connect with clamper link slot 14,24, and exert pressure above casing cover element 20.
As mentioned above, casing cover element 20 is fixed on fiber optics connected with outer casing 10, and the fiber optics pressurization protuberance 21 corresponding with fiber optics 41 exerted pressure to two fiber optics 41 that connect, thus firm connection status.
In addition, in order to remove two fiber optics 41 of connection, need to break mechanical connector 1 time, partition fixed clamp device 30.
That is to say, catch mechanical connector 1 central part, pull out fixed clamp device 30, and along clamper link slot 14,24 slip pressurization lugs 33, thereby fixed clamp device 30 is separated from fiber optics connected with outer casing 10 and casing cover element 20.
Taking apart after fixed clamp device 30, casing cover element 20 is separated from fiber optics connected with outer casing 10, thus the connection of relieving light fiber 41.
These are only preferred embodiments of the present invention, in order to limit the present invention, within the spirit and principles in the present invention not all, any amendment of doing, be equal to replacement, improvement etc., within all should being included in protection scope of the present invention.
