[0002] A fire-proof connecting wire refers to an electrical connecting wire that can maintain its function during a fire. This kind of connecting wire can resist flames and heat for a certain period of time to prevent the spread of fire through electrical circuits. It is usually used in areas of buildings that require fire-proof and flame-retardant requirements, such as stairwells, elevator shafts, etc.
[0003] During the use of the existing fire-proof connecting wires, there are at least the following disadvantages: during the use of the existing fire-proof connecting wires, due to the need to consider fire-proof performance, the wire is relatively thick. Although the fire-proof effect is achieved, the connecting wire is also relatively hard and not conducive to bending use. Therefore, we introduce a fire-proof connecting wire with high flexibility and anti-interference performance. Content of the Utility Model

The diameter of the fire-proof layer is greater than the diameter of the tinned copper shielding net layer. The diameter of the tinned copper shielding net layer is greater than the diameter of the insulating jacket layer.
[0009] By adopting the above technical solution: the tinned copper shielding net layer is a high-density braided structure, which improves the anti-interference effect.
[0010] Preferably, several of the wire cores are annularly distributed.
[0011] Preferably, a plurality of grooves are formed in both the front part and the rear part of the outer surface of the fireproof connection line body.
[0012] By adopting the above technical solution: the grooves are formed in the outer sheath layer and do not penetrate, avoiding the exposure of the fireproof layer.
[0013] Preferably, the plurality of grooves located in the front part of the outer surface of the fireproof connection line body are equidistantly distributed.
[0014] Compared with the prior art, the utility model has the following beneficial effects:
