Embodiment 1

[0035] 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 bonded 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 end ...

Embodiment 2

[0039] according to image 3 , Figure 6 , Figure 7 and Figure 11 As 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.

[0040] 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

[0042] according to image 3 , Figure 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.

[0043] Compared with Embodiment 1, this embodiment makes further limitations on the fixing strip.

Abstract

The invention relates to a novel cable junction box, which comprises a box body. The box body is internally provided with a single fiber fusion splice disc and a cable reinforcement and fixation base.The novel cable junction box is characterized in that the box body comprises an upper box body and a lower box body, which are closed. The two sides of the upper box body and the lower box body are fit up and down through fastening tension bars. Fixation strips comprise upper fixation strips vertically arranged at the two sides of the upper box body and lower fixation strips vertically arranged at the two sides of the lower box body. The upper fixation strips and the lower fixation strips at the same side form a fixation strip group. Each fastening tension bar is provided with a fastening hole matched with the fixation strip group. The cross section area of each fixation strip group decreases gradually from one end of the box body to the other end of the box body. The fixation strip groups are connected to the box body through a fixation dismounting device. The provided novel cable junction box is simple in structure, simple in assembling 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...
