USB application apparatus

Abstract

This invention discloses a USB applied device taking a PCB as the carrier board of a connector, the top surface of the carrier board can load multiple first connecting terminals and its bottom interlayer is formed between the bottom surface of PCB carrier board and the shell layer of the connector, for fixing an electronic component to reduce the length of the USB module or increase its working efficiency and function, besides, a data transmission circuit is set on part of the top surface without the first connection end on the PCB carrier board to increase its working efficiency and function.

Description

technical field [0001] The present invention relates to a USB application device, in particular to an improved structure using a PCB circuit board as an internal bearing board of a connector, which can not only reduce the length of the USB application device, but also effectively improve the working efficiency and functions of the USB application device . Background technique [0002] The USB (Universal Serial Bus) transmission interface is widely used in various computer peripheral devices, information appliances (IA) or 3C consumer electronics products due to its advantages of convenience, expandability and high transmission speed. , is an indispensable transmission interface tool in people's work and family life today. [0003] The existing USB device terminal structure is as follows: figure 1 and figure 2 As shown, a USB application device 10 with a USB connector 11 (Series A Plug), such as an MP3 player or a recorder, etc., has a USB connector 11 at its front end, a...

Problems solved by technology

[0006] In the above-mentioned existing USB application device 10, the carrying plate 111 is a solid resin material, and its only function is to carry and fix the USB connection terminal 13, but it occupies a relatively large volume of the USB connection head 11, relatively It is also difficult to reduce the volume or length of the USB application device 10, so in terms of the production cost and portability of the USB application device 10, a considerable degree of waste and inconvenience are caused.

[0007] In the existing USB connector 11, the top surface of the carrier board 111 only has a VCC power supply line 131, a GND power supply line 137, a D+ transmission line 133 and a D- transmission line 135, and its data transmission line is obviously insufficient, so , its work efficiency and functions are also limited, and it cannot meet the requirements of the information age for the efficiency and functions of information products

[0008] The protective cover 17 of the existing USB application device 10 is fixed on the outer surface of the USB connector 11 in the form of a cover. Although this fixing method can achieve the purpose of protecting the USB connector 11, it also increases the USB application device 10. overall volume

[0009] At the same time, the existing USB connector 11 and the USB shell layer 155 are made of different materials. Therefore, in the manufacturing process, the two must be made separately and then bonded, which not only increases the complexity of the manufacturing, but also makes the bonding process difficult. If the bonding effect is not good, there will be shaking between the USB connector 11 and the USB shell layer 155, which will cause damage to the internal connection lines of the USB application device 10 after long-term use.
