Therefore, when one FC type optical fiber plug is combined with the FC type flange while the SC type optical fiber plug is combined with the clamping groove part, a reliable and high-efficient optical fiber coupling system can be formed on the backplane; the clamping groove part is elastically clamped and fixedly combined with the SC type optical fiber plugs through the clamping part, thereby ensuring that the clamping part and the SC type optical fiber plugs can be easily separated under the strained condition; and meanwhile, compared withthe flange and the connecting seat in the prior art, the flange and the clamping groove part can not only ensure that the industry standards are conformed, but also save more materials.
Description
Technical field
The utility model relates to optical fiber communication physical connection technical field, more particularly, relates 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.
The utility model content
Technical problem to be solved in the utility model 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, the technical solution of the utility model is: a kind of optical fiber backboard adapter is provided, the card slot part that comprises FC type flange, detachably fixedlys 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 with SC type Optical fiber plug elasticity and fixes the holding section that combines.
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 problem to be solved in the utility model, technical scheme and beneficial effect clearer,, the utility model is further elaborated below in conjunction with drawings and Examples.Should be appreciated that specific embodiment described herein only in order to explanation the utility model, and be not used in qualification the utility model.
Please refer to Fig. 1 and Fig. 2, be a preferred embodiment of the present utility model, 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.
