The mechanical connector that being used to of embodiment of the present invention connects fiber optics comprises that mainly fiber optics connects shell 10, casing cover element 20, fixed clamp device 30.
Fiber optics connects shell 10 and comprises square and laterally form, and inserts the insertion section 11 of optical cable 40 and between insertion section 11, the fiber optics connecting portion 12 that is integrated with insertion section 11.
Patchhole 11a is arranged on the insertion section 11, can insert in the patchhole 11a along fiber optics connection shell direction, the optical cable 40 that inserts in central authorities, this is the fiber optics mechanical connector 1 whole core that constitutes.
Promptly as shown in Figures 1 and 2, the xsect of insertion section 11 is a square, be connected fiber optics and connect in the scope of the square cross-sectional shape of casing cover element 20 (aftermentioned) on insertion section 11 on the shell 10 and finish connection, thereby form mechanical connector 1 as shown in Figure 1.
The shape of cross section of above-mentioned insertion section 11 can be a square as depicted in figs. 1 and 2, also can be shapes such as rectangle or circle.
The height of the fiber optics connecting portion 12 that forms between two insertion sections 11 at two ends will be lower than the level of insertion section 11, and it is sagging to downside, lustrous fibre link slot 12a is gone back in inside simultaneously, fiber optics link slot 12a is " v " shape, be used to be connected the fiber optics 41 of two optical cables 40 that the central part of insertion section 11 inserts, come down to a core and encase the retaining part of a core.
Further, the dual-side of fiber optics connecting portion 12 along on transversely arranged a plurality of lug link slots 13 are arranged, be connected lug 23 connections on lug link slot 13 and the casing cover element 20 described later.
On fiber optics connects shell 10 and below, i.e. the following clamper link slot 14,24 that horizontal formation is arranged respectively and be used to be connected and fixed clamper 30 of the top and insertion section 11 of insertion section 11 and fiber optics connecting portion 12.
The length of casing cover element 20 is consistent with the length of fiber optics connecting portion 12, is connected shell 10 with fiber optics and connects, and cover fiber optics connecting portion 12.The bottom surface dual-side of casing cover element 20 is along forming a plurality of connection lugs 23 that protrude downwards simultaneously.
At this, when connecting lug 23 and being connected shell 10 connections at casing cover element 20 with fiber optics, 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 be connected the state that shell 10 connects at fiber optics under, fiber optics connects the clamper link slot 14,24 that forms clamper link slot 14,24 and be adjacent on the shell 10.On the bottom surface of casing cover element 20, form corresponding with fiber optics link slot 12a, and the fiber optics of 41 pressurizations of the fiber optics 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 of the first fixed clamp device and the second fixed clamp device, and simultaneously fixed clamp device 30 has vertical plane 31, prolongs from vertical plane 31, corresponding mutually up and down surface level 32, fixed clamp device 30 be "
" shape.
Further, fixed clamp device 30 is connected the side that fiber optics connects shell 10 and casing cover element 20, its up and down corresponding two surface levels 32 be close to fiber optics connect the top of shell 10 and casing cover element 20 and below, there is pressurization lug 33 inboard of surface level 32, pressurization lug 33 and clamper link slot 14,24 connect, fixed housing cap member 20, and to its pressurization.
Connect at fiber optics on the bottom surface of the shell connecting portion 12 of shell 10 and shell connecting portion 12 corresponding casing cover elements 20 and form first guide groove 15 and second guide groove 22.
First guide groove, 15 front ends are towards fiber optics link slot 12a, the tapered horizontal formation in the both sides in fiber optics connecting portion 12, and be positioned at the place ahead of patchhole 11a.Safe guidance fiber optics 41 enters fiber optics link slot 12a from the place ahead of patchhole 11a by patchhole 11a.
Next the fiber optics connection procedure of mechanical connector that is used to connect fiber optics with regard to embodiment of the present invention is described in detail.
At first, casing cover element 20 is connected shell 10 and connects with fiber optics, and first guide groove 15 is in corresponding state up and down with second guide groove 22, by patchhole 11a insertion optical cable 40, and with the inboard of fiber optics 41 insertion fiber optics connecting portions 12.
At this moment, the fiber optics 41 of insertion is introduced the inboard of fiber optics link slot 12a safely because of first guide groove 15 and second guide groove 22, and is fixed within the fiber optics link slot 12a.
That is to say, when fiber optics 41 enters, even the line end off-center of fiber optics 41 enters, before entering fiber optics link slot 12a, because of first guide groove 15 and second guide groove 22 are guided to the 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 then is connected the side that fiber optics is connected shell 10 and casing cover element 20 with the second fixed clamp device.
Further, in the end of lower horizontal plane on the fixed clamp device 30 with fiber optics connect the side end of shell 10 and casing cover element 20 corresponding after, fixed clamp portion 30 pushes towards fiber optics connection shell 10 and casing cover element 20 external force, and is connected the periphery connection of shell 10 and casing cover element 20 with fiber optics.
At this moment, 33 of pressurization lugs that forms on the surface level of fixed clamp device 30 and clamper link slot 14,24 connect, and exert pressure above casing cover element 20.
As mentioned above, casing cover element 20 is fixed on fiber optics and connects on the shell 10, exert pressure to two fiber optics 41 that are connected with fiber optics 41 corresponding fiber optics pressurization protuberances 21, thus firm connection status.
In addition, in order to remove two fiber optics 41 of connection, when needing partition mechanical connector 1, partition fixed clamp device 30 gets final product.
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 connection shell 10 and casing cover element 20.
After taking fixed clamp device 30 apart, casing cover element 20 connects shell 10 from fiber optics to be separated, thus the connection of relieving light fiber 41.
Below only be better embodiment of the present invention, or not within the spirit and principles in the present invention not all in order to restriction the present invention, any modification of being done, be equal to replacement, improvement etc., all should be included within protection scope of the present invention.
