<p>PROBLEM TO BE SOLVED: To prevent the interruption of a work during the execution or defective bonding during the energization by forming a connector of a metal, a plastic, etc., and keeping its strength to be higher than that of a joint body. SOLUTION: An electrofusion joint is insert-molded with a metallic connector 8 having a flange 8a. Another joint is insert-molded with a metallic connector around a terminal pin. Since the strength of the connector is high, the connector is difficult to break even when an impact is applied during the execution or during the transport of the joint, and the terminal pin is also less damaged. The connector is generally insert-molded, or alternatively, an insertion hole is formed in the joint, the connector is inserted therein, and adhered thereto using an adhesive, or the metallic connector is heated and pressed into the joint, and a resin in contact with the connector is melted for bonding.</p> |
