Abstract: Provided is a female screw connector suitable for connecting pipes. In some embodiments, the female screw connector includes a first body part, a second body part, a rotating connection part, and a fixed connection part. The first body part includes a first external thread portion and a projecting portion, and the second body part includes a second external thread portion and a bolt head portion. The rotating connection part includes a rotation guide portion and a first internal thread portion, and the fixed connection part includes a second internal thread portion. When assembled, the second external thread portion may be threadedly coupled with the second internal thread portion, and the first body part may extend at least partially through the fixed connection part. Also, the first body part, the second body part, the rotating connection part, and the fixed connection part may each be made of a plastic material.

Abstract: A connector is used to connect pipes for conveying a fluid. A plastic male screw connector is manufactured through injection molding of a plastic material to replace a conventional screw connector made of a costly metallic material so that the manufacturing costs can be reduced. Since the screw connector is manufactured through injection molding, mass production of the screw connector becomes possible and the manufacturing costs can be significantly reduced. Also, the plastic material of the screw connector allows for the connector to handle high pressure, resist corrosion and reduce fluid friction.

Abstract: An embodiment of the present invention relates to a connector used to connect pipes for conveying a fluid, and more particularly, to a plastic female screw connector which is manufactured through injection molding to replace a conventional screw connector made of a costly metallic material with an injecting-molded plastic screw connector so that the manufacturing costs can be reduced. According to the plastic female screw connector manufactured through injection molding according to the embodiment of the present invention provides advantages in that, since a screw connector for connecting pipes is manufactured through injection molding of a plastic material, mass production of the screw connector becomes possible and the manufacturing costs can be significantly reduced. Also, because the screw connector is made of the plastic material, excellent pressure resistance with respect to a high pressure, corrosion resistance with respect to a fluid used, and friction resistance can be accomplished.
