Manufacturing method of cable connector assembly

Abstract

The invention discloses a manufacturing method of a cable connector assembly. The manufacturing method is characterized by comprising the following steps: step S1: a plug connector is provided, wherein the plug connector comprises an insulating body, multiple terminals accommodated in the insulating body and a shielding case surrounding the insulating body, and the shielding case is provided witha base and a butting part extending from the base to be inserted into a pair of connectors and electrically connects a cable and the terminals; step S2, a shell covers the base and the cable and fixesthe shell and the shielding case; step S3, injection molding of an inner mold is performed in the shell and the cable is fixed; step S4, the upper surface of the shell is located and injection molding of a first outer mold is performed to cover the lower surface of the shell and the lower surface of the inner mold; and step S5: the lower surface of the first outer mold is located and injection molding of a second outer mold is performed to cover the upper surface of the shell and the upper surface of the first outer mold so that the second outer mold and the first outer mold are joined and the structure of the first outer mold and the second outer mold is uniform.

Description

[0001] 【Technical field】 [0002] The invention relates to a manufacturing method of a cable connector assembly, in particular to a manufacturing method of a high-speed transmission cable connector assembly. [0003] 【Background technique】 [0004] The conventional manufacturing method of the cable connector assembly provides a male head, electrically connects the male head to the cable, sets a metal shell on the periphery of the male head, forms a first insulating member in the metal shell to fix the cable, and then The outer periphery of the first insulator is one-time injection molded to form the second insulator to cover the male head, the first insulator, the metal shell and the cable. However, since the second insulator has to cover multiple components such as the male head, the first insulator, the metal shell, and the cable, the volume of the second insulator must be very large, and the pressure during plastic injection is prone to occur during the injection molding pro...

Problems solved by technology

However, since the second insulator has to cover multiple components such as the male head, the first insulator, the metal shell, and the cable, the volume of the second insulator must be very large, and the pressure during plastic injection is prone to occur during the injection molding process. Inhomogeneity, so that the second insulating part will eventually have the problems of lack of glue, shrinkage and uneven thickness; at the same time, since the second insulating part is only molded by one-time injection molding, when performing the molding step of the second insulating part, the mold It is necessary to have thimbles against the upper and lower surfaces of the metal shell for positioning. Therefore, after forming the second insulating part, there must be a through hole on the upper and lower surfaces of the second insulating part for the thimble to be pulled out, and the existence of the through hole will make The metal shell is exposed to the outside air, and long-term use will affect the electrical performance and service life of the cable connector assembly; in addition, the lack of glue, uneven thickness and the existence of through holes will affect the user's ability to plug and unplug the cable connector Feel when assembling
