Claims (1)
電線を多数設けてなる多芯耐火電線の分岐接続部におい
て、個々の上記電線を段剥ぎして導体同士を接続すると
ともに、個々の上記接続導体と当該耐火被覆層にかけて
耐火層を介在してゴムテープ層を設け、ついで、上記接
続部の多数を一括して、その接続部と多芯幹線シース部
にかけて、高温時に高流動性をもつ未加硫ゴム被覆層を
設け、さらに、その外周にプラスチック被覆層を形成し
て構成されることを特徴とする耐火電線の分岐接続部。At the branch connection part of a multi-core fireproof electric wire, which is made up of a large number of fireproof electric wires each having an insulating coating layer interposed on the conductor, each of the above-mentioned electric wires is stripped in stages and the conductors are connected to each other. A rubber tape layer is provided between the connecting conductor and the fireproof covering layer with a fireproof layer interposed therebetween, and then a large number of the connecting parts are collectively wrapped around the connecting parts and the multi-core main line sheath to ensure high fluidity at high temperatures. What is claimed is: 1. A branch connection part for a fire-resistant electric wire, characterized in that the branch connection part is provided with an unvulcanized rubber coating layer, and further includes a plastic coating layer formed on the outer periphery of the unvulcanized rubber coating layer.
