<p>PROBLEM TO BE SOLVED: To prevent deformation and breakage of a connector pin and prevent deformation and breakage of a connector guide protecting the connector pin. SOLUTION: In the electrically fused joint, the connector pin 3 for energizing a heating wire embedded in an inner circumferential face of the joint is projected to an external surface of the joint 1 and a cylindrical connector guide 5 is provided around the connector pin 3. It is characterized by that a protective cap 11 having an external surface closely contacting an internal surface of the connector guide 5 and a flange part 12 with an end face external surface spread wider than an outer circumference of the connector guide is attached to the connector guide 5.</p> |
