Electric connector and production method therefor

Abstract

The invention discloses a method for producing an electric connector. The method comprises the following steps of providing a grounding metal sheet; arranging an inner insulating base on the grounding metal sheet in an injection molding manner; forming a first positioning bearing part, positioned on the upper side of the grounding metal sheet, and forming a second positioning bearing part, positioned on the lower side of the grounding metal sheet, on the inner insulating base; providing a first conductive terminal group, enabling the first conductive terminal group to be fixedly placed on the first positioning bearing part; providing a second conductive terminal group, enabling the second conductive terminal group to be fixedly placed on the second positioning bearing part so as to enable the metal sheet, the inner insulating base, the first conductive terminal group and the second conductive terminal group to form an assembling body together; arranging an outer insulating base on the assembling body in an injection molding manner; and providing a shell, and enabling the shell to be fixedly arranged on the outer insulating base in a sleeving manner. Therefore, the contact between the first and second conductive terminal groups and the grounding metal sheet can be prevented, so that combustion accidents caused by short circuits in the use process can be avoided; and in addition, the method has simple production procedures and the production cost is lowered.

Description

Technical field [0001] The invention relates to the technical field of electronic devices, in particular to an electrical connector and a production method thereof. Background technique [0002] With the rapid development of science and technology in the field of electronic devices, the volume of electronic products has increasingly developed along the trend of lightness, thinness and shortness, which also requires smaller and smaller components of electronic products. Among them, electrical connectors are particularly prominent. [0003] At present, the more commonly used production method for the electrical connector of the USBType-C socket end is to first perform injection molding (InsertMolding) the first and second insulating seats on the upper and lower rows of conductive terminal groups to form the upper and lower rows of conductive terminals. The grounding metal sheet is clamped between the upper and lower rows of conductive terminal blocks, and the third insulating base is...

Problems solved by technology

[0004] However, in the above-mentioned method for producing an electrical connector at the USB Type-C socket end, on the one hand, the front ends of the conductive terminal groups of the formed upper and lower rows of conductive terminal blocks are exposed and suspended, so the upper and lower row of conductive terminal blocks and the grounding When the third insulating seat is injection-molded on the metal sheet, due to the extrusion of the injection fluid and other reasons, it is easy to cause the terminals of the upper and lower conductive terminal groups and the grounding metal sheet to bend and deflect, so that the terminals of the upper and lower conductive terminal groups and the grounding metal sheet Chip contact, resulting in accidents caused by short circuit during use, which is very unsafe to use; on the other hand, the production process is cumbersome and complicated, and automatic production cannot be realized, the production efficiency is low, and the yield rate is low, making the production cost high. no less
