Abstract

The utility model discloses a flat band optical cable distributing box which comprises a box body, wherein, an optical fiber cable inserting end and an optical fiber leading-out end are arranged on the box body; the box body consists of an upper cover and a lower cover; a sunken position and a convex position are respectively arranged on the left side and the right side of the upper cover; a convex position and a sunken position which respectively correspond to the sunken position and the convex position of the upper cover are respectively arranged on the left side and the right side of the lower cover, thereby sliding chutes are formed on both sides of the upper cover and the lower cover and can facilitate mutual slippage of the upper cover and the lower cover backwards and forwards; when the slippage reaches the degree that the upper cover and the lower cover are completely aligned, the convex positions and the sunken positions are respectively and completely clamped, and the slippage can not be continued. Because the distributing box is divided into two parts of the upper cover and the lower cover, the assembly is convenient; and because only the sliding chutes and bulges for articulation are used as connecting mechanisms of the upper cover and the lower cover, the structure is simplified and optical fibers and cables are protected, and the volume is effectively reduced.

Description

Bandlet optical cable junction box

Technical field:

The utility model relates to a kind of bandlet optical cable junction box.

Background technology:

Present general bandlet optical cable junction box, 12 core bandlet junction boxs for example, fiber-optic output is an elongated opening behind its separated time, and optical fiber is divided into two-layer up and down herein, and capacity causes that optical fiber fractures; And its size is big, and the development that is connected miniaturization with optical fiber is incompatible.

Summary of the invention:

The purpose of this utility model is exactly in order to overcome the above problems, and a kind of bandlet optical cable junction box is provided, and gives under the situation of optical fiber cable with better protection, reduces volume.

The utility model realizes that the scheme of above-mentioned purpose is: a kind of bandlet optical cable junction box, comprise box body, optical cable insertion end optical fiber exit is arranged on the box body, it is characterized in that: described box body comprises loam cake and lower cover, described loam cake depression position and a boss each side arranged, then respectively there are one and above-mentioned depression position and corresponding boss of boss and depression position in the left and right sides of described lower cover, thereby the both sides at loam cake and lower cover form slide-matching groove, loam cake and lower cover are slided front and back mutually, when sliding into loam cake and lower cover complete matching, each projection, the depression position tightens fully, can not continue to slide again.

Adopt the beneficial effect of above scheme: junction box is divided into two parts of upper and lower covers, be convenient to assembling, and only there is slide-matching groove in the bindiny mechanism between the two, by the simplification of structure, when giving optical fiber cable, reduced volume effectively like this with protection.

Embodiment:

Also in conjunction with the accompanying drawings the utility model is described in further detail below by specific embodiment.

Referring to Fig. 1-3, the bandlet optical cable junction box in this example forms a box body by loam cake 1, lower cover 2, and rearward end has optical cable insertion end, leading section that the optical fiber exit is arranged on the box body.Optical fiber exit at leading section has spacer holes 4, so that the optical fiber non-interference behind the separated time, for multifiber is discerned, can write

number designation

1,2 on the spacer holes next door ... or English alphabet label A, B ... Deng, corresponding with the optical fiber of different colours respectively.52 is the optical fiber that has 0.9 mm dia sleeve pipe among Fig. 3.Optical cable input end in rearward end has plastic cement sheath 3, and it provides protection for optical cable, and 5 is the bandlet optical cable, and it stretches into junction box from plastic boot 3, and 51 is bare fibre, and 53 is the LC type joints of optical fibre.

Shown in Fig. 4-7, described loam cake 1 depression position 11 and a boss 12 each side arranged; Shown in Fig. 8-11, then respectively there are one and above-mentioned depression position 11 and boss 12 corresponding boss 22 and depression position 21 in the left and right sides of described lower cover 2, thereby the both sides at loam cake 1 and lower cover 2 form slide-matching groove, and loam cake 1 and lower cover 2 are slided front and back mutually.

Because the width difference at slide-matching groove two ends, therefore, when not having complete matching, loam cake 1 and lower cover 2 can not form and closely cooperate, and can not tighten fully; When alignment, each projection, depression position tighten fully, and upper and lower covers (1,2) can not continue to slide again, can guarantee to play the protective effect to optical fiber like this.

During assembling, can earlier bandlet optical cable 5 be inserted in the sheath 3, will put 0.9 mm dia overcoat behind the fiber-optic sub-line, and each optical fiber is enclosed within outward in the lower cover 2 in spacer holes 4, sequences successively by color, position; Part in the box is glued; then loam cake 1 is slided left by slide-matching groove; be integrated with lower cover 2; up to the slide-matching groove complete matching of upper and

lower covers

1,2 and tighten; upper and lower, left and right all can not be moved again between loam cake 1 and the lower cover 2 at this moment, can play a good protection to the light optical cable.

Claims
