Problems solved by technology

[0002] With the continuous deepening of TD construction, the demand for integrated cables in the market is also increasing. After the integrated cables are laid in the early stage, after a period of use, there will be various unfavorable factors affecting the environment, such as: rainwater backflow, Some equipment in the base station was damaged; when the inventor was looking for how the rainwater poured into the base station from the integrated cable, he found that when the cluster cable connected the two devices, there was a large bending part in the middle. It is found that the rainwater accumulated in the sheath and outside the single-core cable can flow out smoothly; in general, when building a base station, the antenna and RRU are installed in parallel, but there is obviously a difference in height. When the connector is installed at the high end, they are connected separately. When reaching one port, in case of rain, the rainwater will flow down from the branched single-core cable and accumulate in the outer sheath, while the other end is closed, and the integrated connector is directly connected to the outer sheath completely. Sealed together and connected to the equipment at the other end, the accumulated rainwater will slowly seep into the connector and then into the equipment, causing damage to the equipment

Embodiment 1

[0018] This embodiment provides a protective and filterable integrated cable, the structure of which is as follows figure 1 As shown, it includes the outermost outer protective sheath 1, the first braided layer 2 located in the outer protective sheath, and the multi-core integrated cable located in the first braided layer. The multi-core integrated cable includes multiple single cables and located in each single The filling column 8 between the cables is composed of a single cable from the inside to the outside in order of the inner conductor 7, the insulating layer 6, the shielding tape 5, the second braiding layer 4 and the sheath 3, and the outer protective sheath 1 is distributed with the same or different shapes. Through the slot 9. The shape of the through slot 9 is polygonal, and the shape can be rhombus, triangle, or pentagon. The distribution density of the through slots is less than or equal to three per meter of length, and the maximum opening size of the through sl...

Embodiment 2

[0020] This embodiment is the processing method of the outer protective sheath of the protective filterable integrated cable in Example 1. The outer protective sheath is formed by extruding plastic continuously from the head of the extruder and concentrically extruding it with the center of the integrated cable in a surrounding positional relationship. After the integrated cable exits the head of the extruder, it passes through a punching device that is set concentrically by the outer fixed knife holder and the inner rotating knife holder. The convex contact piece corresponding to the punching knife, the inner rotating knife holder rotates at a certain speed, when the integrated cable exits the extruder head and passes through the center of the inner rotating knife holder, the inner rotating knife holder touches the outer fixed knife through the punching knife The convex contact part of the tool holder, the punching knife is pressed down on the outer protective sleeve to form a...

Embodiment 3

[0023] This embodiment is a punching device used for the processing method of the outer protective sheath of the filterable integrated cable. The structure is as follows: figure 2 As shown, it includes an outer fixed knife rest 10 and an inner rotating knife rest 11, the outer fixed knife rest 10 and the inner rotating knife rest 11 are arranged in concentric circles, the outer surface of the inner rotating knife rest 11 is provided with a punching knife 12, and the inner rotating knife rest The inner surface of the frame 11 is provided with a convex contact piece 13 corresponding to the punching knife. The punching knife is installed on the inner rotating knife holder by a spring. The shape of the edge of the punching knife is corresponding to the required shape of the integrated cable through the slot hole.

[0024] External fixed knife holder - there is a convex contact piece on the inner surface of the fixed knife holder. When the inner rotating knife holder rotates, the p...

Abstract

The invention relates to a cable and its processing method, which is a processing method and a punching device for a protective filterable integrated cable and its protective cover, including the outermost outer protective cover and the first braided layer inside the outer protective cover And the multi-core integrated cable located in the first braiding layer. The multi-core integrated cable consists of multiple single cables and filling columns between each single cable. The single cables are inner conductor, insulating layer, shielding tape, The second braiding layer and the sheath, and the outer protective sheath are distributed with through slots with the same or different shapes. The present invention forms slots with the same shape or different shapes on the outer protective cover, which is beneficial to the use in different environments, especially for the filtration of rainwater, preventing rainwater from pouring into the equipment and damaging the system equipment. Considering the cost increase and complicated construction caused by rainwater intrusion, the speed of network construction is improved from all aspects, the cost of network construction is reduced, and it is more conducive to the stability and optimization of the network.
