In such way, when the FC type optical fiber is combined with the FC type flange and the SC type optical fiber plug is combined with the card slot part, the reliable and efficient fiber coupling system can be realized in the backboard place; the card slot part is combined fixedly with the SC type optical fiber plug elastic card through the card merging part, thus the card merging part and the SC type optical fiber plug are easy to be separated in the state of bearing force; simultaneously, compared with the flange and connection seat in the prior art, the structure of the flange and card slot part in the invention save more material in accordance with the industry standards.
Description
Technical field
The present invention relates to optical fiber communication physical connection technical field, more particularly, relate to a kind of optical fiber backboard adapter.
Background technology
In the prior art, the method that two different fiber are continued comprises following two kinds, and a kind of is that two different optical fiber permanent fixations are connected; A kind of is to utilize connector (adapter that connector generally includes Optical fiber plug and removably connects with this Optical fiber plug) to flexibly connect.Flexible connection has the advantage that can repeat to continue, thereby has obtained utilization widely.
The development of FTTH (Fiber To The Home) is arrived user terminal with optic fibre extension, and the quantity of fiber adapter is explosive growth.In this case, cost is exactly the important indicator of fiber adapter competitive power of concerning.
The production of various adapters mainly comprises following two kinds of technologies in the prior art:
The one, utilize the processing of metal material car pin, this technology exists production efficiency lower, the shortcoming that material and production cost are high;
The 2nd, utilize plastic material injection moulding processing, adapters such as for example traditional SC, LC, MU, MT-RJ, MPO, MPT, E200 all are plastic material, but because the structure of adapter is comparatively complicated, above-mentioned each parts substantially all form by ultrasonic soldering, and this just makes adapter finished product packaging efficiency still very low.
So under the prerequisite that guarantees the adapter performance, how to realize reducing cost and can produce just the become industry technical matters being badly in need of solving in enormous quantities.
Various adapter of the prior art has all adopted outward appearance and the structure that meets industry standard, and the consumption of material is bigger usually.Therefore, realizing identical function and can meet under the condition of industry standard that how the structure of reducing adaptor also is to reduce the effective means of adapter manufacturing cost with economical with materials.
In addition, after being connected, need between SC type Optical fiber plug and the Connection Block in the prior art to rely on instrument to dismantle, and the complex structure of Connection Block, materials are more.
Summary of the invention
Technical matters to be solved by this invention is to provide a kind of optical fiber backboard adapter, and it can constitute reliably and cheaply fiber coupling system with Optical fiber plug.
For solving the problems of the technologies described above, technical scheme of the present invention is: a kind of optical fiber backboard adapter is provided, comprise FC type flange, the card slot part of detachably fixedlying connected with described FC type flange, be positioned at the collimation part that described FC type flange and card slot part wear for optical fiber, described card slot part has the holding section that combines with the fixing of SC type Optical fiber plug elasticity, described card slot part comprises flange connecting portion and holding section, described holding section fixes around described SC type Optical fiber plug and with described SC type Optical fiber plug elasticity and combines, described FC type flange inner wall is provided with at least one boss, the lateral wall of described card slot part flange connecting portion is provided with the quantity L shaped draw-in groove corresponding with described boss, described L shaped draw-in groove comprises Outboard Sections and inside part, described Outboard Sections extends along the length direction of described collimation part, and described inside part extends along the outer wall of described flange connecting portion.
Like this, when FC type Optical fiber plug combines with FC type flange, and SC type Optical fiber plug can be realized reliably and efficiently fiber coupling system at the backboard place when combining with card slot part; Described card slot part fixes with SC type Optical fiber plug elasticity by the holding section and combines, and this also makes described holding section and SC type Optical fiber plug easier quilt under stressed state split; Simultaneously, the structure of flange and card slot part meets under the situation of industry standard in assurance, compares with flange of the prior art and Connection Block and saves material more.

Embodiment
In order to make technical matters to be solved by this invention, technical scheme and beneficial effect clearer,, the present invention is further elaborated below in conjunction with drawings and Examples.Should be appreciated that specific embodiment described herein only in order to explanation the present invention, and be not used in qualification the present invention.
Please refer to Fig. 1 and Fig. 2, be a preferred embodiment of the present invention, the card slot part 2 that comprises FC type flange 1, detachably fixedlys connected with described FC type flange 1, be positioned at the collimation part 3 that described FC type flange 1 and card slot part 2 wear for optical fiber, described card slot part 2 has the holding section 21 that combines with the fixing of SC type Optical fiber plug 4 (please refer to Fig. 5) elasticity.Like this, when FC type Optical fiber plug (not shown) combines with FC type flange 1, and SC type Optical fiber plug 4 can be realized reliably and efficiently fiber coupling system at the backboard place when combining with card slot part 2; Described card slot part 2 fixes with SC type Optical fiber plug 4 elasticity by holding section 21 and combines, and this also makes described holding section 21 split with SC type Optical fiber plug 4 easier quilt under stressed state; Simultaneously, the structure of flange 1 and card slot part 2 meets under the situation of industry standard in assurance, saves material more.
Below above-mentioned each ingredient is described in detail respectively.
Described card slot part 2 is made by nonmetallic materials, and comprises flange connecting portion 22 and holding section 21, and described holding section 21 is around described SC type Optical fiber plug 4 and have back-off 211 with its fastening.For convenience of entering of SC type Optical fiber plug 4, described back-off 211 has the inclined-plane towards described SC type Optical fiber plug 4.After SC type Optical fiber plug 4 enters, back-off 211 promptly with SC type Optical fiber plug 4 on boss 41 fix.
Described holding section 21 comprises and described SC type Optical fiber plug 4 fastens circle segment 213 and the resiliency supported part 212 between described circle segment 213 and described flange connecting portion 22.Like this, when needs split SC type Optical fiber plug 4, at A on (please refer to Fig. 5), push described circle segment 213 and resiliency supported part 212, make it produce elastic deformation, thus increase B among Fig. 5 to size, can make that described back-off 211 is easier to break away from SC type Optical fiber plug 4.
In order further to increase elasticity, in the present embodiment, described resiliency supported part 212 is two elasticity fins that extend along described collimation part 3 length directions.
