Method for manufacturing a connector, and connector

Abstract

To provide a manufacturing method for a connector that can suppress galvanic corrosion from occurring, and a connector.SOLUTION: A manufacturing method for a connector 1 includes: a braided-body arranging step (a step 2) of arranging an end part 31a of a braided body 30 at an outside of a shield shell 20; a conductive resin member arranging step (a step S3) of arranging a conductive resin member 40 at an outside of the braided body to cover an end part 20a of the shield shell with the conductive resin member; a coating step (a step S4) of melting the conductive resin member by heat and coating an end part of the braided body with molten resin 40P; a fixing member arranging step (a step S5) of arranging a fixing member 50 at an outside of a coated portion 34 formed of the coated end part of the braided body; and a swaging step (a step S6) of fixing the braided body to the shield shell with the coated portion coating the end part of the shield shell.SELECTED DRAWING: Figure 7

Claims

1. A braided body arrangement step involves arranging the ends of a braided body, which is formed in a cylindrical shape from a conductive metal material and has a surface made of a different metal than the metal forming the shield shell, on the outside of a shield shell, which is formed in a cylindrical shape from a conductive metal material and houses a part of the housing that holds the terminal provided at the end of the electric wire. A conductive resin member is placed on the outside of the braided body, and a conductive resin member formed in a cylindrical shape from a synthetic resin material containing a conductive material and having insulating properties is placed, and the end of the shield shell is covered with the conductive resin member. A coating step is performed in which the conductive resin member is sandwiched between each of the heating jigs, thereby melting the conductive resin member with heat, and coating the ends of the braided body with the molten resin. A fixing member placement step involves arranging a fixing member, which is formed in a cylindrical shape, on the outside of the covered portion formed by coating the end of the braided body, The invention is characterized by including a crimping step of fixing the braided body to the shield shell by crimping the fixing members with each of the crimping jigs while the covering portion covers the end of the shield shell, A method for manufacturing connectors.

2. In the braided body placement step, the ends of the braided body are positioned in a state where they abut against positioning portions that protrude from the outer surface of the shield shell. In the conductive resin member placement step, the end of the conductive resin member is positioned in a state where it abuts against the positioning portion.
