Embodiment 1

[0030] Such as figure 1 , figure 2 , image 3 and Figure 4 As shown, an ant-proof optical cable, comprising: an optical cable main part 1, the optical cable main part is provided with a core part 2, a flame-retardant layer 3, a waterproof layer 4, a capillary layer 5 and a PVC layer 6 sequentially from the inside to the outside, The core part includes a skeleton 7 and an optical fiber 8 attached to the skeleton. Fiber paste is filled between the skeleton and the optical fiber. The capillary layer is made of a material with capillary pores. Percentage 1%-3% pyrethrin solution.

[0031] The outer surface of the PVC layer is a smooth curved surface, and the PVC layer is provided with several strip-shaped installation grooves 9, the bottom wall of the installation groove has a perforation 10 connecting the capillary layer, and several sealing strips 11 are housed in the installation groove. Also can be equipped with strip anti-termite assembly 12 on. The anti-ant component ...

Embodiment 2

[0035] Such as Figure 5 As shown, an ant-proof optical cable includes a main part of the optical cable. The main part of the optical cable is sequentially provided with a core part, a flame-retardant layer, a waterproof layer, a capillary layer, a smooth PVC layer on the outer surface and a capillary tube from the inside to the outside. The core part includes The skeleton and the optical fiber attached to the skeleton are made of a material with capillary pores, and the anti-ant solution is adsorbed in the capillary layer.

[0036]The PVC layer is connected with an anti-ant component integrally formed with the PVC layer. The anti-ant component includes a storage capsule storing an anti-ant solution, a burr tube and a connection block. One end of the connection block is connected to the storage capsule, and the other end is connected to the PVC layer. The capillary runs through the connection Block and PVC layer, one end of the capillary communicates with the inner cavity of t...

Abstract

The invention discloses an ant-proof optical cable, comprising: a main part of the optical cable, the main part of the optical cable is sequentially provided with a core part, a flame-retardant layer, a waterproof layer, a capillary layer and a PVC layer, and the core part includes For the frame and the optical fiber attached to the frame, the capillary layer is made of a material with capillary holes, and the capillary layer is adsorbed with an anti-termite solution. In the present invention, a capillary layer and a waterproof layer are arranged between the PVC layer and the flame-retardant layer. The capillary layer can absorb a large amount of anti-ant solution. The solution will be continuously transferred to the gap, the anti-ant effect lasts for a long time, and the anti-ant effect is better.

Description

technical field [0001] The invention relates to the field of optical cable production, in particular to an ant-proof optical cable. Background technique [0002] Optical cables are manufactured to meet optical, mechanical or environmental performance specifications. It is a communication cable assembly that uses one or more optical fibers placed in a sheath as a transmission medium and can be used individually or in groups. The basic structure of an optical cable is generally composed of several parts such as a cable core, a reinforced steel wire, a filler, and a sheath. In addition, there are components such as a waterproof layer, a buffer layer, and an insulated metal wire as required. [0003] Existing optical cables basically use physical methods to prevent termites. Generally, nylon sleeves are added to the outer surface of the optical cable to enhance its surface smoothness to reduce termites. The anti-termite effect is poor and cannot last; , often by spraying anti-t...
