A kind of usb plug structure and its manufacturing method

Abstract

The invention belongs to the technical field of connectors, and in particular relates to a USB plug structure and a manufacturing method thereof, including a metal shell, a rubber core, a terminal group and a PCB board. The terminal group includes a front terminal and a back terminal, and the front terminal It is set on the front side of the PCB board, and the reverse side terminal is set on the back side of the PCB board. The whole formed by the terminal group and the PCB board is embedded in the rubber core, and the rubber core is inserted into the metal shell; the part of the back side terminal protruding from the PCB board is provided with an arc shape. department. Compared with the prior art, the present invention arranges the front terminal and the back terminal on the PCB board, so that the front terminal and the back terminal share one data transmission line, which can reduce the material of the terminal and the processing procedure of the terminal, thereby saving cost. Moreover, the part protruding from the PCB board of the reverse terminal of the present invention is provided with an arc portion, and when the female seat contacts the front and reverse sides of the present invention, the arc portion can play the role of strengthening 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 standardize the connection and communication between computers and external devices. product. 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 socket on computer, install plug on computer peripheral equipment, plug is inserted into socket when connecting, makes both produce electric connection.

AI Technical Summary

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.
