Electric wire connector having fire-extinguishing function

An electric wire connector having fire-extinguishing function includes: a protective holder (100) comprising a conductor cap (120) and an insulator gap (140), wherein the conductor cap (120) accommodates a conductor part 12 of an electric wire connection part (10), wherein the insulator cap (140) wherein the insulator cap (140) has an inner diameter larger than an inner diameter of the conductor cap (120) and accommodates an insulator part (14) of the connection part (10); a metal tube (200) installed within the conductor cap (120) and press-fits in the conductor part (12); and a fire-extinguishing module (300) installed in the insulator cap (140) and having a fire-extinguishing tunnel (302), wherein the fire-extinguishing tunnel (302) is provided in the insulator cap (140), wherein the insulator part (14) is inserted in the fire-extinguishing tunnel, wherein the fire-extinguishing powder is ejected in response to a heat of a fire.
