Problems solved by technology
Usually, a sunken board type USB socket is only suitable for one electronic product, only for the suitable sinking height of the circuit board, but not for another electronic product
The existing Type C products for mobile terminals still have the requirement to transmit large currents. In order to reduce the heat generation of the product transmission terminals, the thickness of the transmission terminals needs to be thickened to reduce the impedance. According to the thickness of the current conventional boards on the market , if the transmission terminals on both sides are thickened, there will be a problem that the gap between the two is too small, and when the power terminal is thicker than the signal terminal, there will be a problem of complicated manufacturing process, which will lead to an increase in manufacturing cost

A USB socket, including a connector and a metal shell sleeved outside the connector, the connector includes a first terminal group, a metal middle plate, and the first terminal group and the metal middle plate are molded An integral first insulator, a second terminal group, and a second insulator integrally formed with the second terminal group and the first insulator, the first and second terminal groups respectively include a pair of outermost A ground terminal, a pair of power terminals located inside the pair of ground terminals, and a number of signal terminals located between the pair of power terminals, the thickness of the first terminal group is greater than the thickness of the second terminal group, so The ground terminal of the first terminal group and the metal middle plate are laminated and fixed to form the first insulator, and the first insulator is provided with a plurality of terminal grooves on the side away from the first terminal group, and the second terminal The second insulator is injection-molded in the terminal groove; the USB socket of this application has strong versatility.
Description
technical field [0001] The application relates to the field of connectors, in particular to a USB socket and a manufacturing method thereof. Background technique [0002] Type C USB sockets are widely used in electronic devices such as mobile phones. According to different application requirements, they are divided into on-board type and sink type. On-board type means that the USB socket is mounted on the surface of the printed circuit board, and sink type The type sinks from the surface of the printed circuit board, so that the thickness of the USB socket is scattered on both sides of the printed circuit board, reducing the overall thickness of the main board. Usually, a sunken plate type USB socket is only suitable for one electronic product, and only for the suitable sunken height of the circuit board, but cannot be applied to another electronic product. The existing Type C products for mobile terminals still have the requirement to transmit large currents. In order to r...
