ELECTRICAL MELTED TYPE CONNECTION FOR EFFECTIVELY COPING WITH THE ELASTICITY OF A SYNTHETIC RESIN PIPE BY THE TEMPERATURE CHANGE

摘要

PURPOSE: An electrical melted type connection is provided to effectively cope with the elasticity of a synthetic resin pipe by the temperature change by compressing an elastomeric packing formed in the inner circumference of an electrical melted packing to the outer circumference of the inserted synthetic resin pipe and melting an upper slope in which an electric heating line of an electrical melted packing is embedded with an inclined packing part of a cylindrical socket.;CONSTITUTION: An electrical melted type connection is composed of a cylindrical socket(110), an electrical melted packing(210), and a pusher(220). The cylindrical socket is attached to one end of a synthetic resin(200) by heat melting. The electrical melted packing is arranged in the synthetic resin pipe to be connected. A hanging projection(113) is formed in the outer circumference of the cylindrical socket attached to one end of the synthetic resin pipe. A projection(111) is formed in the inner surface of the cylindrical socket. An inclined packing melted part(210) is formed at the inlet of the cylindrical socket. An electric heating line(212) having a terminal is embedded in the upper slope of the electrical melted packing arranged in the synthetic resin pipe. An elastomeric packing(215) is installed in the inner circumference of the electrical melted packing. A fastening hole(221) is formed on the outer circumference of the pusher. A pushing projection(222) is formed within the inner surface of the pusher.;COPYRIGHT KIPO 2010
