  • Tubular resin connection structure
    Patent number: 6722708
    Abstract: A tubular resin connection structure is disclosed that includes a resin connector and a resin tube. The resin tube is fixedly coupled to one of the first and second ends of the resin connector in a fluid-tight manner by a weld disposed between the resin connector and the resin tube. Preferably, one end of the resin tube is inserted into a molding die and a portion of the resin connector is welded to the resin tube by overmolding the resin of the resin connector during injection molding. In other words, the weld between the resin connector and the resin tube is formed overmolding a resin of the resin connector over the resin tube to simultaneously mold the resin connector and form the weld between the resin connector and the resin tube.
