Optical fiber splicing box

Cable connecting box, also called the cable connector box and barrel, is the end of the local access cable, and then through the optical fiber jumper access optical switch, prevent the nature of hot and cold, light, oxygen and microbial materials caused by aging, and has excellent mechanical strength, optical cable connector box shell and a rigid body structure able to bear the worst environmental change at the same time, flame retardant, waterproof, shock, impact, stretch and twist protected cable.

Internal structure editor

1 、 support frame: the main part of the internal component.

2 、 fiber optic fixing device: used for fixing fiber cable and base and strengthening of optical fiber cable. First, the cable reinforcement core in the internal fixation; two is the fiber optic cable and supporting frame clamping fixed; three is the optical cable and connector box, the cable in and out with heat shrinkable sheath sealed fixed. [1]

3, the fiber placing device: a sequentially stored optical fiber connector and the remaining fiber, the remaining optical fiber length should be less than 1 meters, the remaining PAN fiber paths of not less than 35mm. Wherein, the accommodating tray is more than four layers, and the capacity is large, and the accommodating disk can be adjusted according to the number of cores connected by the optical fiber cable.

4 、 fiber optic joint protection: after the heat shrinkable protective sleeve is placed in the receiving tray, the fixed clamp on the core can also be fixed by silica gel.

5, cable and connector box sealing of junction cable and at the base of the cable inlet box and cable connector with emery cloth for grinding, polishing the detergent clean, aluminum paste, and then placed in the heat shrinkable tube connector box into the cable, use a blowtorch according to the middle to the ends of the slow heating the heat shrinkable tube, can be completely shrink.

Application editor

The utility model is suitable for the straight through and the branch connection of various structural cables, such as overhead, pipeline, direct buried and other laying modes.

Connection in the terminal room of a structural optical cable.

Optical fiber splicing boxes are usually suitable for outdoor use in indoor or outdoor areas. They are not suitable for outdoor use. If they are to be used, protective measures should be taken. Working temperature: indoor type: -5 DEG C, ~+40 DEG C, outdoor type: -20 DEG C, -+60 DEG C.

Feature editor

The utility model can play the role of protection and continuity, and the box body adopts reinforced plastic, which has the advantages of high strength, corrosion resistance, mature structure, reliable sealing and convenient construction.

Classified editor

According to the optical fiber cable connection mode, it can be divided into straight through type and different type.

Depending on whether the assembly adapter can be assembled, it can be divided into assembly adapter type and non assembly adapter type.

According to the shell material classification, can be divided into plastic shell and metal shell.

Edit by usage

Fiber preparation

1. remove the fiber sheath (if any, please remove the shield and armor), then remove the wrapping layer to expose the loose sleeve, the specific method, according to the optical fiber manufacturer recommended standard method steps, preparation length 3m.

2. Clean the loose sleeve and reinforce the core sheath with detergent, remove the excess filling casing and polish the 150mm length of the fiber sheath with the sand paper provided.

Fiber optic cable installation

1. Select the minimum inner diameter seal ring according to the outer diameter of the optical cable and cover the two sealing rings on the optical fiber cable.

2. Place the cable in the corresponding hole.

3, connection shielding and grounding.

4. Self sealing adhesive tape is wound between the two sealing rings so that the sealing belt is wound to the outer diameter of the sealing ring so as to form a sealing end of the optical fiber cable.

5, the optical fiber sealing end into the optical cable into the hole.

6, through the cable reinforced hose clamps the fixed seat and the cable core is fixed on the bracket, the optical cable connector box base, tighten the screw hose clamps, hose clamps pull tight until now.

7, in the optical cable on the nylon tie tape, cut the remaining length.

8, the rest of the cable hole, please use a plug seal. The same sealing tape is applied to the plug and requires the same as 5.2.4.

9. The reinforcing member is wound on the countersunk head screw of the weld plate support and pressed.
