High-temperature-resistant flame-retardant cable and manufacturing method thereof

Abstract

The invention relates to a high-temperature-resistant flame-retardant cable, which comprises a battery cell and a cable connector, the battery cell is wrapped with a flame-retardant layer, and wavy protrusions are formed on the outer surface of the flame-retardant layer; the flame-retardant layer is wrapped with a waterproof heat conduction layer; the cable connector comprises an insulating tube,annular inner cavities are formed in the two ends of the insulating tube, a conductive block is fixed to the middle of the insulating tube, conical grooves are formed in the two ends of the conductiveblock, and fixing grooves matched with the battery cells are formed in the bottoms of the conical grooves. The annular inner cavity is communicated with an injection hole; and the two cables are connected through a cable joint and then glue is injected into the annular inner cavity. The contact area of the flame-retardant layer and the waterproof heat conduction layer is increased through the wavy protrusions, rapid heat dissipation of the cable is facilitated, the temperature of the cable is prevented from rising too fast, glass fibers are added into the waterproof heat conduction layer to form a heat conduction wire structure, the toughness of the outer layer is improved, and the heat conduction performance of the outer layer is improved. The leakproofness of cable connection is ensuredthrough the special cable joint, and the defect of short circuit caused by easy water seepage at the joint is overcome.

Description

Technical field: [0001] The invention belongs to the field of cables, in particular to a high-temperature-resistant flame-retardant cable and a manufacturing method thereof. Background technique: [0002] The cable is usually made of a battery core and an outer rubber insulating sheath. However, due to the electrification of the cable, it is easy to cause the temperature to be too high, which makes the rubber insulation sheath melt, and then damages or even burns, causing danger. Invention content: [0003] The object of the present invention is to provide a high-temperature-resistant flame-retardant cable and its manufacturing method. The present invention increases the contact area between the flame-retardant layer and the waterproof heat-conducting layer through wavy protrusions, which facilitates rapid heat dissipation of the cable and prevents the temperature of the cable from rising too much. Fast, and glass fiber is added to the waterproof and heat-conducting layer...
