Implement the joints of optical fibre of the present invention, there is following beneficial effect: in the joints of optical fibre of the present invention, Optical fiber plug and fiber adapter fasten in the periphery of fiber adapter, improved the structure of the joints of optical fibre, can effectively utilize the space of adapter inside, avoid, due to the too small structural strength to Optical fiber plug body of physical dimension of Optical fiber plug body and the impact that operation brings, being particularly useful for the occasion that optical fiber high density connects.
Accompanying drawing explanation
Below in conjunction with drawings and Examples, the invention will be further described, in accompanying drawing:
Fig. 1 is the decomposing schematic representation of the first embodiment of the joints of optical fibre of the present invention;
Fig. 2 is the decomposing schematic representation of the second embodiment of the joints of optical fibre of the present invention.
Embodiment
In the high density of optical fiber connects, undersized due to Optical fiber plug, be subject to the restriction of the materials such as working of plastics wall thickness and structure, the undercapacity that can cause Optical fiber plug arranges the button bit of too much dimple-shaped simultaneously due to the inwall of the housing at adapter, also can reduce the intensity of the housing of adapter, in order to improve this situation, in the present invention, the Promethean fastening structure by connector is arranged on adaptive periphery, can improve like this intensity of the joints of optical fibre.
For technical characterictic of the present invention, object and effect being had more clearly, understand, now contrast accompanying drawing and describe the specific embodiment of the present invention in detail.
As shown in Figure 1, the first embodiment for the joints of optical fibre of the present invention, comprises Optical fiber plug 100, and with the fiber adapter 200 of Optical fiber plug 100 adaptations.In the present embodiment, the basic size of fiber adapter 200 is basic identical with the installation dimension of two slotting LC shape optical fiber adaptations, the physical dimension of Optical fiber plug 100 has reduced a lot, adaptive 200 1 sides of this optical fiber can be inserted four Optical fiber plugs 200, with respect to two-way connection before, Connection Density is doubled.Measure-alike due to the size of fiber adapter 200 and the fiber adapter of existing LC, can not need to change support or the panel of distribution plant inside, only change connector and just can realize significantly improving of optical fiber Connection Density, be conducive to save replacement cost.
Fastening in the present embodiment arm 120 is flexibly connected with header body 110, and further, for buckle portion 121 is coordinated with button bit 214 reliably, fasten between arm 120 and header body 110 and be provided with flexible member 130, the front end that flexible member 130 makes to fasten arm 120 is pressed on button bit 214 in case clamping portion 121 is thrown off by button bit 214.Particularly, the middle part that fastens arm 120 has a connecting piece 123, this brace 123 extends to form along the vertical direction that fastens arm 120 by fastening arm 120, in header body 110, there are two auricles 111, 112, brace 123 is positioned at two braces 111, between 112, bearing pin 125 is through two auricles 111, 112 and brace 123 make to fasten arm 120 and form and be rotationally connected with header body 110, in the present embodiment, flexible member 130 is torsion spring, on brace 123, there is the sleeve 126 perpendicular to brace 123, torsion spring set is on sleeve 126, because the overall dimensions of Optical fiber plug 100 is less, so torsion spring and brace 123, the size of bearing pin 125 is all smaller, the assembling that sleeve 126 can facilitate torsion spring etc. is set.
In the present embodiment, button bit 214 is for being formed at the groove on the outer wall of housing 210, the place ahead of button bit 214 is provided with the guide portion 215 for guiding the front end of fastening arm 120 to enter button bit 214, for convenient, coordinate, a side of guide portion 215 is lead-in chamfered 216, when Optical fiber plug 100 is inserted in adapter 200, buckle portion 121 is crossed guide portion 215 along lead-in chamfered 216, after crossing guide portion 215, due to the effect of flexible member, buckle portion 121 is buckled in button bit 214.In order better to guide and to fasten arm 120, in lead-in chamfered 216, be provided with dividing plate 217, between adjacent separator 217, can hold one and fasten arm 120, can play better guide effect like this.
It will be appreciated that the concrete form that does not limit to this enforcement of button bit 214 can be any applicable forms such as other grooves or pit.When Optical fiber plug 100 is extracted, press the rear end that fastens arm 120, buckle portion 121 is deviate from button bit 214, then Optical fiber plug 100 is outwards extracted.
As shown in Figure 2, the second embodiment for the joints of optical fibre of the present invention, the present embodiment is compared with the first embodiment, its difference is, appearance at adapter housing 210 is provided with buckle portion 218, and be provided with the button bit 127 with buckle portion 218 adaptations at the front end that fastens arm 120, during fastening, buckle portion 218 buckles in button bit 127, equally, in order to guarantee to fasten arm 120 and button bit 127 no-floats, between buckle portion 218, be provided with dividing plate 217, dividing plate 217 can play certain guide effect, other structures of the present embodiment are identical with the structure of first embodiment, repeat no more.
In the joints of optical fibre of the present invention, Optical fiber plug and fiber adapter fasten in the periphery of fiber adapter, improved the structure of the joints of optical fibre, can effectively utilize the space of adapter inside, avoid, due to the too small structural strength to Optical fiber plug body of physical dimension of Optical fiber plug body and the impact that operation brings, being particularly useful for the occasion that optical fiber high density connects.
By reference to the accompanying drawings embodiments of the invention are described above; but the present invention is not limited to above-mentioned embodiment; above-mentioned embodiment is only schematic; rather than restrictive; those of ordinary skill in the art is under enlightenment of the present invention; not departing from the scope situation that aim of the present invention and claim protect, also can make a lot of forms, within these all belong to protection of the present invention.
