Problems solved by technology
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

A surface-mounted-type USB connector comprises a metal isolation piece, a first terminal set, a first plastic body, a second terminal set, a second plastic body a fixed clamping piece and a metal shell. The metal isolation piece and the first terminal set are integrally formed inside the first plastic body. The second terminal set is integrally formed inside the second plastic body. The first plastic body and the second plastic body are fixedly clamped into a whole through the fixed clamping piece. The first plastic body comprises a base portion, a first fixed clamping portion and a butt-joint tongue portion, wherein the base portion extends forwards to form the first fixed clamping portion, and the first fixed clamping portion extends forwards to form the butt-joint tongue portion. An installation groove is formed in the side, close to the butt-joint tongue portion, of the base portion. The second plastic body comprises a second fixed clamping portion and an installation portion, wherein the second fixed clamping portion corresponds to the first fixed clamping portion, and the installation portion is formed at the rear end of the second fixed clamping portion and contained inside the installation groove. The surface-mounted-type USB connector can be plugged forwards and reversely.
Description
technical field [0001] The invention relates to the field of electrical connectors, in particular to a chip-type 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 spac...
