Abstract

The invention discloses a plastic connector and a manufacturing method thereof. The manufacturing method of the plastic connector is characterized by mainly comprising the steps that: raw materials after being dried and proportioned are added into a heated injection molding machine, and a final qualified product can be obtained by setting injection pressure, injection speed, injection time and injection rubber quantity of different sections of the injection molding machine and by simultaneously setting the final pressure maintaining pressure and final pressure maintaining speed to realize the best injection molding technique. Weaknesses on the physical properties of the molded plastic connector that the product is easy to pull apart to break, the flexibility is poor, the strength is low and the like can be overcome when in molding. At the same time, the injection molding technique is stable, the obtained product quality is stable, the production efficiency is improved, and the production cost is reduced.

Description

Background technique [0001] The invention relates to a plastic connector and a manufacturing method thereof, belonging to the technical field of automobile manufacturing. Background technique [0002] With the progress of society, the use of automobiles is increasing. The connecting plugs for system signal transmission include non-integral metal or plastic plugs. There are wire contact components in the plastic plugs, and a plug at the other end of the plastic plugs. Connecting plug-in, connecting plug-in combination contact assembly is inserted at the other end of the plastic plug body, the above-mentioned knot has disadvantages such as inconvenient assembly, inaccurate positioning, unstable connection, insufficient connection strength and affecting contact performance. Contents of the invention [0003] In order to alleviate the deficiencies and defects of the prior art, the purpose of the present invention is to provide a plastic connector and its manufacturing method. ...
