Universal serial bus (USB) plug structure capable of being positively and reversely inserted and manufacturing method of USB plug structure

Abstract

The invention belongs to the technical field of connectors, and particularly relates to a universal serial bus (USB) plug structure capable of being positively and reversely inserted and a manufacturing method of the USB plug structure. The USB plug structure comprises a metal shell, a rubber core, a terminal group and a printed circuit board (PCB), wherein the terminal group comprises a front terminal and a reverse terminal; the front terminal is arranged on the front surface of the PCB; the reverse terminal is arranged on the reverse surface of the PCB; a whole body formed by the terminal group and the PCB is embedded into the rubber core; the rubber core is inserted into the metal shell; and an arc part is arranged at the part, which extends outside the PCB, of the reverse terminal. Compared with the prior art, the front terminal and the reverse terminal are arranged on the PCB, so that the front terminal and the reverse terminal share a data transmission line; and the materials of the terminals and the manufacturing procedures of the terminals can be reduced to reduce the cost. Furthermore, the arc part is arranged at the part, which extends outside the PCB, of the reverse terminal; and when a female base contacts the front surface and the reverse surface of the USB plug structure, the arc part can play roles in increasing force and rebounding.

Description

technical field [0001] The invention belongs to the technical field of connectors, and in particular relates to a USB plug structure and a manufacturing method thereof which can be plugged in front and back. Background technique [0002] USB (Universal Serial Bus, Universal Serial Bus) is an external bus standard used to regulate the connection and communication between computers and external devices. It is also a technical specification for input and output interfaces, and is widely used in information communication products such as personal computers and mobile devices. With the rapid development of electronic technology, the application of USB plugs is becoming more and more extensive, and USB occupies an important position in the electronic field. The vast majority of computer peripherals are connected to the computer via USB for data transmission and exchange, such as mice, keyboards, U disks, printers, mobile phones, and cameras. Like this, just need to install USB so...

Problems solved by technology

[0003] Since the electrical connection points of the plug and the socket itself are designed in a one-to-one correspondence, wrong insertion will cause major dangers such as invalidity or even burning out the equipment.

In order to prevent people from plugging in wrongly when using the USB interface, the USB interface has a fool-proof design, that is, the plug and socket will need to be aligned in the direction because of their single-sided insertion characteristics, which requires a lot of waste. Checking and proofreading time

In this way, when users use it, they often need to check which direction the socket is in, and then adjust the plug to the same direction before inserting it, or if it is not inserted correctly, change the direction and then insert it. The plug or socket is broken, causing a lot of trouble

Moreover, the structure of the traditional USB connector is formed by punching a metal sheet, and then the contact piece is embedded in the metal forming piece to fix the shape, the production process is complicated, and the production cost is high.
