ELECTRIC WIRE CONNECTOR HAVING FIRE-EXTINGUISHING FUNCTION

WIPO Patent Application WO/2021/235599

A1

The present invention provides an electric wire connector having a fire-extinguishing function. That is, the present invention comprises: a protective holder (100) which comprises a conductor cap (120) for receiving a conductor part (12) of an electric wire connection part (10), and an insulator cap (140) formed so as to be expanded than the inner diameter of the conductor cap (120), and receiving an insulator part (14) of the connection part (10); a metal tube (200) which is installed inside the conductor cap (120) so as to press-fit and bind the conductor part (12); and a fire-extinguishing module (300) which is installed in the insulator cap (140), has a fire-extinguishing tunnel (302) formed so that the insulator part (14) is penetratingly inserted therein, and reacts to heat of a fire, and thus ejects fire-extinguishing powder. By using the electric wire connector having the fire-extinguishing function, the fire-extinguishing powder is automatically ejected by reacting to heat at the time of ignition of a spark which could occur at the electric wire connection part, and thus the ignition may be suppressed at an early stage, and thus an advantage is achieved of being capable of preventing a large fire in advance.
