Description

Technical Field

[0001] The utility model mainly relates to the technical field of cables, in particular to an ultraviolet light cross-linked cable. Background Art

[0002] Cables are commonly used conductors in daily life, transmitting electricity or information from one place to another. At present, with the development of society, electricity consumption has also increased, and the requirements for cables have become higher and higher. When a certain load current passes through the cable, it will definitely heat up. As the load current increases, the cable surface temperature will be higher. If the current carrying capacity of the wire and cable exceeds its limit carrying capacity, it may cause a fire due to untimely heat dissipation, resulting in loss of life and property. The traditional heat dissipation method is to reduce the thickness of the cable core protective layer to improve the heat dissipation effect of the cable, but it will increase the possibility of cable damage. How to effectively improve the heat dissipation effect of the cable is an urgent problem to be solved.

[0003] Therefore, a UV cross-linked cable is needed to solve the above problems. Utility Model Content

[0004] The technical solution of the utility model aims at the technical problem that the existing technical solution is too single, provides a solution that is significantly different from the existing technology, and mainly provides a UV light cross-linking cable to solve the technical problems raised in the above background technology.

[0005] The utility model adopts the following technical solution to solve the above technical problems: a UV cross-linked cable, comprising a wrapping layer, wherein the outer ring of the wrapping layer is connected and fixed to a plurality of cable bodies arranged in an annular shape and at equal intervals, a main hole is provided in the middle position of the wrapping layer, and a plurality of connecting holes are provided in the main hole in an annular shape and at equal intervals.

[0006] Preferably, the outer ring of the wrapping layer is connected and fixed to a plurality of outer wrapping sheets which are arranged equidistantly in a ring shape, and the outer wrapping sheets are gap-fitted with each other.

[0007] Preferably, an edge through hole is formed between the outer sheet and the wrapping layer.

[0008] Preferably, the communicating hole is communicated with an overload device, and the overload device comprises a communicating pipe, and the communicating pipe is communicated with the communicating hole.

[0009] Preferably, one end of the connecting pipe away from the connecting hole is connected and fixed to the filter screen.

[0010] Preferably, the wrapping layer and the cable body are formed by extrusion. The connecting tube and the connecting hole are connected by hot melting.

[0011] Compared with the prior art, the utility model has the following beneficial effects: when the wrapping layer is bent by external influence, the internal air will be squeezed out, and after being reset, the wrapping layer will no longer be squeezed to let in air, thereby realizing ventilation in the main hole. At the same time, if it rains, rainwater can flow in to dissipate heat and then be discharged by evaporation.

[0012] When the water depth in one of the edge through holes is higher than that in the connecting tube, the overloaded water will enter the connecting tube and then the main hole, and then enter other connecting tubes from the main hole, and finally enter other edge through holes, so that the excess water is evenly distributed and retained by the outer wrapping sheet, thereby ensuring comprehensive cooling and heat dissipation of the cable body.

[0018] In order to facilitate the understanding of the present invention, the present invention will be described in more detail below with reference to the relevant drawings. Several embodiments of the present invention are given in the drawings, but the present invention can be implemented in different forms and is not limited to the embodiments described in the text. On the contrary, these embodiments are provided to make the content disclosed in the present invention more thorough and comprehensive.

[0019] It should be noted that when an element is referred to as being "fixed on" another element, it may be directly on the other element or there may be a central element. When an element is considered to be "connected to" another element, it may be directly connected to the other element or there may be a central element at the same time. The terms "vertical", "horizontal", "left", "right" and similar expressions used in this article are for illustrative purposes only.

[0020] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly connected by technicians in the technical field of the present invention. The terminology used in the specification of the present invention is for the purpose of describing specific embodiments and is not intended to limit the present invention. The term "and / or" used herein includes any and all combinations of one or more related listed items.

[0021] See also Figure 1-3 A UV cross-linked cable comprises a wrapping layer 1, the outer ring of the wrapping layer 1 is connected and fixed to a plurality of cable bodies 2 arranged in an annular shape and at equal intervals, and the wrapping layer 1 and the cable body 2 are formed by extrusion. A main hole 11 is provided in the middle of the wrapping layer 1, and a plurality of connecting holes 12 are provided in an annular shape and at equal intervals in the main hole 11. When the wrapping layer 1 is bent by the external influence, the internal air is squeezed out, and after reset, the wrapping layer 1 is no longer squeezed to take in air, thereby realizing ventilation in the main hole 1. At the same time, if it rains, rainwater can flow in to dissipate heat and then be discharged by evaporation.

[0022] The outer circle of the wrapping layer 1 is connected and fixed to a plurality of outer wrapping sheets 4 equidistantly arranged in a ring shape, and the outer wrapping sheets 4 are gap-matched with each other, so that the outer wrapping sheets 4 can further protect the cable from damage. At the same time, an edge through hole 41 is formed between the outer wrapping sheet 4 and the wrapping layer 1. Due to the gap-matched with each other, when the outer wrapping sheet 4 is deformed, air or water can enter more quickly to exchange ventilation and water, thereby achieving the effect of rapid heat dissipation.

[0023] The connecting hole 12 is connected to the overload device 3, and the overload device 3 includes a connecting tube 31. The connecting tube 31 is connected to the connecting hole 12. When the water depth in one of the edge through holes 41 is higher than the connecting tube 31, the overloaded water will enter the connecting tube 31 and enter the main hole 11, and then enter other connecting tubes 31 from the main hole 11, and finally enter other edge through holes 41, so that the excess water is evenly distributed and retained by the outer sheet 4, so as to ensure comprehensive cooling and heat dissipation of the cable body 2.

[0024] One end of the connecting pipe 31 away from the connecting hole 12 is connected and fixed to the filter screen 32. The filter screen can prevent the connecting pipe 31 from being blocked, ensuring that the water distribution will not be blocked. The connecting pipe 31 is connected to the connecting hole 12 by hot melting.

[0025] The outer covering sheet 4 and the cable body 2 are formed by extruding the outer covering sheet 4 through the casting head through an extruder. The viscous fluid is pushed to the head and coated on the surface of the cable body 2 through the rotation of the screw and the pressure. Finally, the outer covering sheet 4 is cooled through a cooling water trough or a cooling pipe, and is changed from an amorphous plastic state to a fixed solid state. Then, threaded holes are opened at equal intervals through a tap, and the overload device 3 is connected to the threaded hole at a low cost.

[0026] The above description of the utility model is exemplified in combination with the accompanying drawings. It is obvious that the specific implementation of the utility model is not limited to the above-mentioned method. As long as the non-substantial improvements are made by adopting the method concept and technical solution of the utility model, or the concept and technical solution of the utility model are directly applied to other occasions without improvement, they are all within the protection scope of the utility model.
