USB plug connector with function of forwarding and reverse plugging, and manufacturing method therefor

Abstract

The invention discloses a USB plug connector with a function of forwarding and reverse plugging, and the connector comprises a shielding housing, an insulating substrate disposed in the shielding housing, and a tongue plate suspended at the front end of the insulating substrate. The upper and lower surfaces of the tongue plate are respectively provided with a conductive terminal strip, and conductive terminals from the left to the right on the upper surface are sequentially connected with conductive terminals from the right to the left on the lower surface in a one-one corresponding manner. The conductive terminals and the tongue plate are molded together in an insetting manner through injection molding. The conductive terminals stretches out from the rear end of the tongue plate to form pins, and the pins and the insulating substrate are molded together in an insetting manner through injection molding. Connection parts between the conductive terminals and the pins are exposed between the tongue plate and the insulating substrate. The conductive terminals on the upper and lower surfaces of the tongue plate are molded through integrated punch molding, replaces a mode that the conventional technology employs a PCB board for through connection, does not need welding, is low in number of parts, greatly simplifies the manufacturing technology through the provided manufacturing steps, reduces the cost, and is more stable in quality.

Description

technical field [0001] The invention relates to the technical field of electrical connectors, in particular to a USB plug connector with forward and reverse insertion functions and a manufacturing method thereof. Background technique [0002] As the application fields of digital products and communication equipment become wider and wider, people need to import or export usage data from digital products or communication products more and more during use. Charging of communication products; however, the existing USB plug connectors are divided into upper and lower plugs. When using, the upper and lower parts of the USB plug connector must be distinguished before they can be correctly inserted into the USB socket, which is very inconvenient to use. [0003] At present, there is a double-sided USB plug connector, that is, it can be plugged in front or back, and there is no need to distinguish the front and back of the USB plug connector, which is more convenient to use. However...
