Description

Technical Field

[0001] The utility model relates to the technical field of cable bushings, in particular to a heat dissipation type cable bushing. Background Art

[0002] Cable casing, also known as cable protection tube or conduit, is a protective tube with a certain mechanical strength to prevent cables and wires from being damaged and protect the outer layer of the cable, which can help wires and cables to pass through. The existing cable casing is closed inside and cannot help the cable to dissipate heat. The heat dissipation is poor. When multiple cables and wires are inserted into the cable casing, the cables are gathered in one place without isolation, causing the local heat temperature in the casing to rise rapidly. The risk of short circuit and fire is easy to occur between the cables in the closed casing with poor heat dissipation, which greatly increases the safety hazard. Utility Model Content

[0003] The utility model aims at the deficiencies of the prior art and provides a sleeve with good heat dissipation to solve the above problems.

[0004] The utility model is realized through the following technical scheme: a heat-dissipating cable bushing, comprising a bushing body, an outer tube is fixedly connected to the outer surface of the bushing body, an annular heat-dissipating cavity is formed between the outer tube and the bushing body, an inner tube is passed through the bushing body, a plurality of isolation plates are arranged between the inner tube and the bushing body, the plurality of isolation plates are distributed along the circumference of the inner tube and extend along the length direction of the inner tube, a threading cavity is formed between adjacent isolation plates, and a heat-dissipating structure connected to the heat-dissipating cavity is arranged on the threading cavity.

[0005] In this scheme, the interior of the casing body is isolated by several isolation plates to form several threading cavities, and the isolation distance between cables is increased by the inner tube. The casing body and the heat dissipation structure are protected by the outer tube. A cable is passed through each threading cavity to achieve isolation and dispersion between cables, thereby dissipating the heat in the casing body. The heat in each threading cavity is transferred and dissipated to the heat dissipation cavity through the heat dissipation structure and mixed with the surrounding air, further improving the heat dissipation effect of the cable and improving safety.

[0006] As an optimization, the heat dissipation structure includes a plurality of heat sinks, and a mounting groove connecting the heat dissipation cavity and the threading cavity is opened on the outer wall of the sleeve body, and the plurality of heat sinks are fixed in the mounting grooves at intervals. This optimization transfers heat in the threading cavity through the heat sink, and the heat sink intervals are arranged to form gaps between the heat sinks, so that heat dissipates from the gaps to the outside, thereby accelerating the heat dissipation speed.

[0007] As an optimization, the sleeve body is provided with a plurality of groups of the heat dissipation structures at intervals along the length direction. This optimization further improves the heat dissipation efficiency of the heat in the threading cavity.

[0008] As an optimization, one end of the isolation plate is fixedly connected to the outer wall of the inner tube, and the other end of the isolation plate is slidably connected to the inner wall of the casing body through a dovetail groove structure. The optimized inner tube can be slidably removed through the isolation plate, so that a cable with a larger diameter can be inserted into the casing body, thereby improving applicability.

[0009] As an optimization, both ports of the heat dissipation cavity are provided with protective nets. This optimization isolates debris through the protective nets.

[0010] As an optimization, both ends of the outer tube are fixedly connected with an annular flow guide cover, the inner hole of the flow guide cover is connected with the heat dissipation cavity, and the outer wall and the inner wall of the flow guide cover are connected in an arc transition in the direction away from the outer tube. In this optimization scheme, the flow guide cover strengthens the two ends of the outer tube and has a shielding effect.

[0011] As an optimization, both ends of the sleeve body are fixedly connected with a funnel-shaped fixing cover, and the shrinking end of the fixing cover is arranged away from the sleeve body. This optimization strengthens the two ends of the sleeve body through the fixing cover and tightens the cable.

[0012] The beneficial effects of the utility model are as follows: the inner cavity of the sleeve body is divided into a plurality of threading cavities by the cooperation of the inner tube and the isolation plate, thereby avoiding heat concentration between cables and providing the effect of dispersing heat, while also enhancing the structural strength of the cable sleeve. The dispersed heat is transferred and dissipated into the heat dissipation cavity through the heat dissipation structure, further improving the heat dissipation effect and improving the safety of use.
