USB interface connecting line with expansion port

Abstract

The invention discloses a USB interface connecting line with an expansion port, and particularly relates to the technical field of USB interface connecting lines. The technical scheme is that the USB interface connecting line comprises an interface body and a protective shell, a main USB plug is installed at the top of the interface body, the bottom of the main USB plug is fixedly connected with an expansion socket, an expansion USB plug is installed on one side of the expansion socket, the top of the extension socket is provided with a heat dissipation hole, the inner wall of the heat dissipation hole is sleeved with a dustproof net, the bottom of the extension socket is fixedly connected with a first handheld plate, the outer surface of the first handheld plate is fixedly sleeved with a spliced rubber rib, the bottom of the first handheld plate is provided with an anti-breaking protective sleeve, the outer surface of one side of the anti-breaking protective sleeve is provided with an extrusion open groove, and the outer surface of the anti-breaking protective sleeve is sleeved with a sliding plate. The USB interface connecting line has the anti-breaking and anti-falling properties, is good in heat dissipation performance and high in dust prevention performance, has the interface protection effect, and prolongs the service life.

Description

technical field [0001] The invention relates to the technical field of USB interface connection lines, in particular to a USB interface connection line with an expansion port. Background technique [0002] USB is the most widely used external bus standard in the PC field. It is used to standardize the connection and communication between computers and external devices. The USB interface supports plug-and-play and hot-swappable functions of devices. With the rapid development of computer hardware, The application of USB increases the speed of data transmission between external devices. The biggest benefit of the increase in speed for users is that users can use more efficient external devices. For example, with a USB 2.0 scanner, scanning a 4M picture only takes 0.1 second or so, the work efficiency is greatly improved. According to different interfaces and data cables, USB supports devices: mouse, keyboard, printer, scanner, camera, flash disk, MP3 machine, mobile phone, dig...

[0002] USB is the most widely used external bus standard in the PC field. It is used to standardize the connection and communication between computers and external devices. The USB interface supports plug-and-play and hot-swappable functions of devices. With the rapid development of computer hardware, The application of USB increases the speed of data transmission between external devices. The biggest benefit of the increase in speed for users is that users can use more efficient external devices. For example, with a USB 2.0 scanner, scanning a 4M picture only takes 0.1 second or so, the work efficiency is greatly improved. According to different interfaces and data cables, USB supports devices: mouse, keyboard, printer, scanner, camera, flash disk, MP3 machine, mobile phone, digital camera, mobile hard disk, external Electronic products such as optical floppy drive, USB network card, ADSLModem, Cable Modem, etc. Nowadays, many electronic devices we use can be operated through the USB interface, such as: mobile phones, mp3, digital cameras, etc. If you use a desktop computer, it is better , there are many USB interfaces, but notebooks do not have such conditions, and even some notebooks only have one USB interface, and you need to plug in the mouse. If you need to connect your mobile phone to the notebook through the USB interface at this time, think about it. Look, this is really a disaster, we have to remove the mouse temporarily, and use the touchpad mouse under the keyboard of the notebook. It looks bulky, so how to choose a suitable and expandable USB cable has become a problem that people should consider when shopping in computer stores. When we use USB cables, only one USB cable can be inserted into one port. Sometimes we need to connect If you insert multiple USB devices, but the ports are insufficient, other devices will be unusable.

[0003] The existing technology has the following disadvantages: the existing USB interface and connecting wire are easy to fall off during use, and the anti-breakage, heat dissipation and dustproof properties are not good, and the service life is low
