Abstract

The utility model relates to an insert type optical branching device, comprising an insert box, an optical adapter and an optical branching device main body. The insert box comprises a box body, a box cover and a stop rod. The box body, the upper and lower parts of the stop rod and the box cover are respectively provided with 9 optical adapter slot positions, a barrier is arranged between every 2 slot positions, and a slot position is reserved at the far left. The front surface of the box body is provided with 4 fixing buttons, inserts are arranged at the left and right of the exterior, 4 fixing keys are arranged on inner sides, and the left and right of the front end of the interior are respectively provided with a sliding groove. The upper and lower parts of the stop rod are provided with the slot positions, the left and right sides are provided with L-shaped sliding rods, and the sliding rods and the sliding grooves of the box body are combined. The box cover is provided with 4 locking hooks which are combined with the fixing keys of the box body. The optical adapter is an SC type. The optical branching device main body is a PLC type with an SC-type connector, and the light splitting ratio is M*N (M is 1 or 2, N is 4, 8, 16, 32, 64). According to the insert type optical branching device, a reasonable packaging structure is provided, the structure is compact, the operation is simple, a more convenient routing mode is provided for the FTTH (fiber to the home), and the optical signal distribution of tail ends of the FTTH is completed.

Description

A kind of insert type optical branching device

Technical field

The utility model relates to a kind of optical branching device, particularly a kind of insert type optical branching device.

Background technology

In recent years, domestic telecommunication industry capital construction speed is constantly accelerated, 7 ministries and commissions such as Ministry of Industry and Information, National Development and Reform Committee united in 2010 and issue the documents, require telecom operators to accelerate to advance the fiber broadband construction, accelerate the city Fiber to the home and propose coming years urban subscribers and will realize average 8M broadband access ability.

Project that Fiber to the home in various places now starts comprehensively, and plane waveguide light shunt is one of core component of FTTH.By casing is set in corridor, the mode of configuration PLC optical branching device transfers to the light signal distribution in the user family in the casing.Be to save cabinet space, the PLC optical branching device needs a kind of rational encapsulating structure, should handled easily, reduce again volume.Insert type optical branching device uses with the inserted sheet form, and encapsulating structure is compact, and is simple to operate, can solve this problem.

Summary of the invention

Technical matters to be solved

The technical problems to be solved in the utility model provides a kind of insert type optical branching device.

Technical scheme

Described insert box is comprised of box body, lid, pin.About box body, the pin, lid all has 9 optical adapter groove positions, per 2 groove interdigits have jube, Far Left stays single groove position.

Described box body is just being worn 4 fixedly knobs, is with inserted sheet about the outside, and there are 4 retainingf keys the inboard, and the groove position of interior forward end bottom is separated by jube, respectively is with chute about interior forward end.

Described pin all has up and down the groove position, and the groove position is separated by jube, about the L-type slide bar is arranged, slide bar combines with the box body chute.

The groove position is arranged at described lid front end bottom, and the groove position is separated by jube, and lid has 4 lock hooks, combines with the retainingf key of box body.

Described optical adapter is the SC type.

Described optical branching device main body is the PLC type, band SC type connector, splitting ratio be M*N (M be 1 or 2, N be 4,8,16,32,64).

Description of drawings

Fig. 1 is this insert type optical branching device;

Fig. 2 is box body structure figure;

Fig. 3 is the lid structural drawing;

Fig. 4 is the pin structural drawing.

Embodiment

The utility model is described in further detail below in conjunction with the drawings and specific embodiments.

As shown in Figure 1, insert type optical branching device comprises insert box, optical adapter 4, optical branching device main body 5.Insert box comprises box body 1, lid 2, pin 3.Optical adapter 4 is the SC type, and one deck can be arranged 9, adopts the groove position of box body 1, pin 3, lid 2 to fix.Pin 3 can slide up and down along the chute 11 of box body 1 front end, reaches the purpose of fixed light adapter 4.

As shown in Figure 2, box body 1 is just being worn four fixedly knobs 12, band inserted sheet 13 about the outside, and there are four retainingf keys 14 inboard, is used for fixedly lid 2, and the groove position 15 of interior forward end bottom is divided into five zones by jube 16, respectively is with chute 11 about interior forward end.

As shown in Figure 3, lid 2 has four lock hooks 21, combines with the retainingf key 14 of box body 1 during closing lid.

As shown in Figure 4, pin 3 all has up and down groove position 35 and jube 36, about L-type slide bar 31 is arranged, L-type slide bar 31 can slide in the chute 11 of box body 1.
