Waterproof connector and manufacturing method thereof

A method of manufacturing a waterproof connector, the method comprising at least the following steps of:

• (1) placing in an insert molding machine at least one contact made of a conductive material and a shell made of metal interior of which the contact is disposed and an insertion port into which a counterpart connector is inserted on one side, and forming a housing from an insulating resin material by insert molding integrally with the contact and the shell such that the shell is exposed at the outer circumference of and at the vicinity of the insertion port to form an outer circumferential exposure portion;
• and
• (2) disposing, in its entirety, a waterproof portion on the outer circumferential exposure portion of the shell by insert molding the elastic material with the shell so that the water proof portion is integrally formed with the shell, the vicinity of the insertion port of the shell being within the waterproof portion.
