Title:
PLASTIC TUBE CONNECTING METHOD, JOINT TO BE USED FOR IT, PLASTIC TUBE AND MANUFACTURE THEREOF
Document Type and Number:
Japanese Patent JPH07117133
Kind Code:
A
Abstract:
PURPOSE: To surely connect plastic tubes and joints in a short time by a method wherein a high-frequency power source device having low frequency is used so as to be safe and stabilize quality without generating wave trouble.
CONSTITUTION: Joints with embedded bobbins 3 consisting of molded pieces whose inner faces contain ferrite powder mixed therein are inserted into tube ends of plastic tubes 2a and 2b. By using a heating device constituted of a high-frequency generating device, an electrode core and an excitation coil, 1-400kHz of alternating field is generated and the bobbins 3 are heated so as to fuse with heat.
