The joints of optical fibre of embodiment of the present invention; Has 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, have improved the structure of the joints of optical fibre, can effectively utilize the adapter volume inside; Avoid because the too small influence of bringing for Optical fiber plug main body structure intensity and operation of the physical dimension of Optical fiber plug body is particularly useful for the occasion that the optical fiber high density connects.
Description of drawings
To combine accompanying drawing and embodiment that the present invention is described further below, in the accompanying drawing:
Fig. 1 is the decomposing schematic representation of first embodiment of the joints of optical fibre of the present invention;
Fig. 2 is the decomposing schematic representation of second embodiment of the joints of optical fibre of the present invention.
Embodiment
In the high density of optical fiber connects,, receive the restriction of material such as working of plastics wall thickness and structure because Optical fiber plug is undersized; The undercapacity that can cause Optical fiber plug simultaneously owing at the inwall of the housing of adapter the button bit of too much dimple-shaped is set, also can reduce the intensity of the housing of adapter; In order to improve this situation; In the present invention, Promethean fastening structure with connector is arranged on adaptive periphery, can improve the intensity of the joints of optical fibre like this.
To understand in order technical characterictic of the present invention, purpose and effect being had more clearly, to contrast accompanying drawing at present and specify embodiment of the present invention.
As shown in Figure 1, first embodiment for the joints of optical fibre of the present invention comprises Optical fiber plug 100, and the fiber adapter 200 adaptive with Optical fiber plug 100.In the present embodiment; The basic size of fiber adapter 200 is basic identical with pair installation dimension that the LC shape optical fiber of inserting are adaptive; The physical dimension of Optical fiber plug 100 has then reduced a lot; Adaptive 200 1 sides of this optical fiber can be inserted four Optical fiber plugs 200, connect with respect to two-way before, and Connection Density is doubled.Because the size of fiber adapter 200 and the fiber adapter of existing LC is measure-alike; Can not need change distribution plant inner support or panel; Only change connector and just can realize significantly improving of optical fiber Connection Density, help practicing thrift replacement cost.
Fastening arm 120 in the present embodiment flexibly connects with header body 110; And further; For button portion 121 is cooperated with button bit 214 reliably; Fasten between arm 120 and the header body 110 and be provided with flexible member 130, flexible member 130 is pressed on the button bit 214 to prevent that button portion 121 is by button bit 214 disengagements the front end that fastens arm 120.Particularly, the middle part that fastens arm 120 has a connecting piece 123, and this brace 123 extends to form along the vertical direction that fastens arm 120 by fastening arm 120; On header body 110, have two auricles 111,112; Brace 123 is at two braces 111, between 112, and bearing pin 125 passes two auricles 111,112 and brace 123 is rotationally connected fastening arm 120 and header body 110 formations, in the present embodiment; Flexible member 130 is a torsion spring; On brace 123, have 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 the size of torsion spring and brace 123, bearing pin 125 is all smaller, the assembling that sleeve 126 can make things convenient for torsion spring etc. is set.
In the present embodiment, button bit 214 is the groove on the outer wall that is formed at housing 210, and the place ahead of button bit 214 is provided with the guide portion 215 that is used to guide the front end entering button bit 214 that fastens arm 120; Cooperate for ease, a side of guide portion 215 is a lead-in chamfered 216, when Optical fiber plug 100 is inserted in the adapter 200; Guide portion 215 is crossed along lead-in chamfered 216 by button portion 121; Cross after the guide portion 215, because the effect of flexible member is buckled in the button bit 214 button portion 121.To fasten arm 120 in order better guiding, to be provided with dividing plate 217, can hold one between the adjacent separator 217 and fasten arm 120, can play better guide effect like this in lead-in chamfered 216.
It will be appreciated that the concrete form that does not limit to this enforcement of button bit 214 can be any suitable forms such as other grooves or pit.When Optical fiber plug 100 is extracted, push the rear end that fastens arm 120, make button portion 121 by deviating from the button bit 214, then Optical fiber plug 100 is outwards extracted to get final product.
As shown in Figure 2, be second embodiment of the joints of optical fibre of the present invention, present embodiment is compared with first embodiment; Its difference is, is provided with button portion 218 in the appearance of adapter housing 210, and is provided with the button bit 127 adaptive with button portion 218 at the front end that fastens arm 120; During fastening, button portion 218 buckles in the button bit 127, and is same; In order to guarantee to fasten arm 120 and button bit 127 no-floats, be provided with dividing plate 217 between the button portion 218, dividing plate 217 can play certain guide effect; Other structures of 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 adapter volume inside, avoid because the too small influence of bringing for Optical fiber plug main body structure intensity and operation of the physical dimension of Optical fiber plug body is particularly useful for the occasion that the optical fiber high density connects.
Combine accompanying drawing that embodiments of the invention are described above; But the present invention is not limited to above-mentioned embodiment, and above-mentioned embodiment only is schematically, rather than restrictive; Those of ordinary skill in the art is under enlightenment of the present invention; Not breaking away under the scope situation that aim of the present invention and claim protect, also can make a lot of forms, these all belong within the protection of the present invention.
