Reversible usb connector and manufacturing method thereof

Abstract

The invention discloses a USB (universal serial bus) connector capable of being positively and negatively plugged. The USB connector comprises upper and low terminal sets arranged in upper and low rows, grounding components clamped between the upper and lower terminal sets, a front insulator integrally formed at the peripheries of the upper and lower terminal sets, a rear insulator integrally formed at the rear ends of the upper and lower terminal sets, and a metal housing surrounding the periphery of the front insulator, wherein the front insulator comprises a base part, and a butting tongue part formed by forwards extending the base part; conductive terminals of the upper and lower terminal sets, and the grounding components are integrally formed in the butting tongue part of the front insulator; the conductive terminals of the upper and lower terminal sets are exposed to upper and lower surfaces of the butting tongue part; the grounding component is clamped between the upper and lower insulated bases and used for forming the front insulator through injection-molding. According to the USB connector capable of being positively and negatively plugged, the product strength is guaranteed under the circumference that the size is small, and positive and negative plugging compatibility is good.

Description

technical field [0001] The invention relates to the field of electrical connectors, in particular to a reversible USB connector and a manufacturing method thereof. Background technique [0002] The Universal Serial Bus (USB) widely exists in people's daily life, and most electronic equipment data transmission adopts this common standard; the emergence of the USB3.0 standard has greatly improved the data transmission speed, in the standard A Type In terms of USB interface design, USB3.0 can perfectly implement design changes without affecting backward compatibility and structural appearance. However, in the Micro USB field of mobile terminal applications, it is impossible to achieve functional upgrades while ensuring that the structural appearance remains unchanged. The Micro USB 3.0 standard eventually complicates the appearance and structure, that is, an interface is added in a side-by-side manner to accommodate the increased functional solder pins. , but takes up more spa...

However, in the Micro USB field of mobile terminal applications, it is impossible to achieve functional upgrades while ensuring that the structural appearance remains unchanged. The Micro USB 3.0 standard eventually complicates the appearance and structure, that is, an interface is added in a side-by-side manner to accommodate the increased functional solder pins. , but takes up more space, limited to the development trend of ultra-thin smartphones, the application of Micro USB3.0 on mobile phones is greatly restricted, and a new high-speed serial universal bus is urgently needed to solve this problem question

[0003] The traditional USB connector does not support reverse plugging, and the connection can only be realized after the plug is inserted into the socket correctly
