摘要： 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.

摘要翻译： 公开了包括树脂连接器和树脂管的管状树脂连接结构。 通过设置在树脂连接器和树脂管之间的焊接，树脂管以流体密封的方式固定地连接到树脂连接器的第一端和第二端中的一个。 优选地，树脂管的一端插入成型模具中，并且树脂连接器的一部分在注射成型期间通过树脂连接器的树脂包覆模制而被焊接到树脂管。 换句话说，树脂连接器和树脂管之间的焊接被形成为将树脂连接器的树脂覆盖在树脂管上，同时模制树脂连接器并在树脂连接器和树脂管之间形成焊接。
