Description

Technical Field

[0001] The invention relates to the technical field of cables, and in particular to a segmented fireproof quick-connect cable. Background Art

[0002] In the actual processing and manufacturing of cables, the fire resistance of cables has always been an important indicator. As a power transmission component, the safety of cables is of vital importance. In actual fires or short circuits, the fire resistance of cables is an important performance indicator. Cables are classified in various ways, including coaxial cables. In actual installation work, they are usually installed through cable installation tubes. This can avoid scratching the cables, but also causes the cables to burn quickly along the cable installation tubes once they catch fire. The current fireproof quick-connect cables are not convenient for segmented isolation and fire prevention, which can easily cause the entire circuit to burn. At the same time, the cable connection strength is low, the asbestos fireproof layer has poor pressure resistance, and it is not easy to quickly seal and reduce the oxygen content to assist in fire extinguishing, resulting in large cable fire damage.

At the same time, this structure can fit tightly inside the cable installation tube by adopting a barrier method, and can make full use of the cable installation tube. The smooth inner wall reduces the oxygen content in combustion, further assists in extinguishing fire, and further reduces damage to cables, preventing the entire line from being burned. The closed rubber ring 602 used in this case can be used to shield the plug-in docking column 104 and the flashlight 102 when the expansion moving ring 601 is separated and pushed out by the propulsion spring 6011, thereby improving the safety of power connection during use and avoiding electric shock. The structure is safer and more reasonable, and it also prevents the plug-in docking column 104 and the flashlight 102 from being contaminated. The arc-shaped protrusion structure on the inner side of the fireproof bearing tube 702 is squeezed by the inclined structure of the fireproof bearing tube 702 and expands outward, so as to fit the inner wall of the cable installation tube installed in this structure, thereby achieving fire barrier and air isolation, and the structure is simple and reasonable.

[0040] Working principle of this embodiment: First, the number of sections of the cable body 2 of this structure can be set according to needs, and the electrical connection flashlight 102 and the plug-in installation handle 103 can be installed at the junction of the two cable bodies 2 respectively. The asbestos protective layer 203 on the cable body 2 is used in combination with the fireproof coating 205 and the fireproof bonding cloth 206 to achieve the effect of fire protection. At the same time, the plug-in docking column 104 is inserted into the flashlight 102 to connect the power, and the structure is more reasonable. When overheating occurs, the thermal top pressure column 502 as a thermal sensitive metal ash will melt or soften due to deformation. At this time, the pull-back release spring 503 will pull the plug-in limit block 401 to drive the limit thorn block 402 to separate from the limit plug-in slot 3011. At this time, the limit plug-in slot 3011 loses its limit, and under the extrusion of the expansion separation control component 6, the plug-in docking column 104 can slip out of the flashlight 102, and the thermal control bolt can be turned on. 501 can be used to disassemble the thermal pressure column 502 for replacement. When the expansion moving ring 601 is pushed out by the separation propulsion spring 6011, the closed rubber ring 602 can be used to shield the plug-in docking column 104 and the flashlight 102, so as to improve the safety of power connection during use and avoid electric shock. The structure is safer and more reasonable, and it also prevents the plug-in docking column 104 and the flashlight 102 from being contaminated. When the plug-in docking column 104 slips out of the flashlight 102, with the extrusion of the separation propulsion spring 6011, the plug-in docking column 104 will fall out of the outer ring inside the flashlight 102. During the process, the expansion moving ring 601 is driven to move outward, thereby driving the expansion extrusion ring 604 to move and squeeze the fireproof bearing tube 702. At this time, the arc-shaped convex structure on the inner side of the fireproof bearing tube 702 is squeezed by the fireproof bearing tube 702 with the inclined structure and will expand outward, so as to fit the inner wall of the cable installation tube installed in this structure.
