Embodiment 1

[0038] according to Figure 1 to Figure 11 A new type of optical cable junction box is shown, which includes a box body 10. The box body 10 is provided with a single fiber splicing tray and an optical cable strengthening fixing seat. It is characterized in that the box body 10 includes an upper and lower cover. The box body 1 and the lower box body 2, the two sides of the upper box body 1 and the lower box body 2 are laminated up and down through the fastening bars 3, and the fixing strips include longitudinally arranged on both sides of the upper box body 1. The upper fixing strip 4 on the side and the lower fixing strip 5 vertically arranged on both sides of the lower box body 2, the upper fixing on the same side and the lower fixing strip 5 are combined up and down to form a fixing strip group 11. The fastening bars 3 are provided with fastening holes 6 adapted to the fixed bar group 11, and the cross-sectional area of ​​the fixed bar group 11 gradually decreases from one e...

Embodiment 2

[0042] according to image 3 , Image 6 , Figure 7 and Figure 11As shown in a new type of optical cable junction box, the small ends of the fixing strip groups 11 described on both sides of the box body are arranged alternately from left to right.

[0043] Compared with Embodiment 1, this embodiment further limits the fixing bar group 11, so that the left and right small ends of the fixing bar groups 11 on both sides of the box body are arranged alternately so that the clamping force at the left and right ends of the box body is balanced to avoid a Side clamping force is too high.

Embodiment 3

[0045] according to image 3 , Image 6 and Figure 7 As shown in a new type of optical cable junction box, the cross-section of the fixing bar group 11 is T-shaped, and the upper fixing bar 4 and the lower fixing bar 5 of the same group are arranged symmetrically.

[0046] Compared with Embodiment 1, this embodiment makes further limitations on the fixing strip.

Abstract

The invention relates to a novel optical cable junction box. The novel optical cable junction box comprises a box body, wherein a single-fiber fusion splice tray and an optical cable reinforcing fixing seat are arranged in the box body, and the box body comprises an upper box body and a lower box body which are covered up and down; the two sides of the upper box body and the two sides of the lowerbox body are vertically attached through fastening pull strips; the fastening pull strips comprise upper fixing strips longitudinally arranged on two sides of the upper box body and lower fixing strips longitudinally arranged on two sides of the lower box body; the upper fixing strip and the lower fixing strip on the same side are compounded into a fixing strip group up and down; the fastening pull strips are provided with fastening holes matched with the fixing strip groups; the cross section areas of the fixing strip groups are gradually reduced from one end of the box body to the other endof the box body; and the fixing strip groups are connected with the box body through a fixed dismounting device. The novel optical cable junction box provided by the invention is simple in structure,simple in assembly operation and good in sealing performance.

Description

technical field [0001] The invention relates to a junction box, in particular to an improvement on the structure of a new optical cable junction box and the like. Background technique [0002] Optical cable splice box is a popular name, its scientific name is optical cable splicing box, also known as optical cable splicing package, optical cable splicing package and gun barrel. It belongs to the mechanical pressure sealing joint system and is a splice protection device that provides optical, sealing and mechanical strength continuity between adjacent optical cables. It is mainly suitable for straight-through and branch connections of various structural optical cables in overhead, pipeline, direct burial and other laying methods. The box body is made of imported reinforced plastic, which has high strength and corrosion resistance. The terminal box is suitable for connection in the terminal room of structural optical cables. It has a mature structure, reliable sealing and con...
