Description

Wired network signal external module

technical field

Background technique

At present, hand-held portable devices such as smart phones (iPhone), tablet computers (iPad) or digital players (iPod)... are becoming more and more common, and the hand-held portable devices are all moving toward light, The design is thin, short, and small. Therefore, some devices or connectors that are not commonly used or less portable are often not provided to save the internal space as much as possible, so that the overall volume can be greatly reduced accordingly. For example, it usually has a wireless network module that is easy to carry, but does not have a wired network module that needs to be connected to a network cable and is not easy to carry. Therefore, most of the handheld portable devices that can access the Internet on the market are equipped with a wireless network signal transmitter for receiving wireless network signals on the motherboard and connect the wireless network signal transmitter with a microprocessor (CPU) for use in A network signal processing module that processes and converts network signals, without a wired network electrical connector (RJ45 socket) for plugging in an external network cable and connecting to the network signal processing module. However, although the wireless network is more convenient at present, it is still not as stable and fast as the wired network for the transmission of large amounts of data. Therefore, the handheld portable device still often needs to use the wired network access function.

Currently, the handheld portable devices on the market are usually connected with a communication interface converter for network cable connection to increase the wired network access function. Commonly known communication interface converters on the market at present, as shown in the patent No. M312716 of China Taiwan Announcement, it mainly has a USB plug that can be plugged into the USB electrical connector of the hand-held portable device, and can be used for the connection of the network line. An RJ45 socket that the RJ45 plug is plugged into, and a network signal processing module that connects the two between the USB plug and the RJ45 socket, and uses the network signal processing module to perform USB signals and RJ45 signals (network signals) ) for signal processing and conversion. In this way, when using a wired network, the network signal processing module can be used to convert the network signal received by the RJ45 socket into a USB signal, and then the USB signal processing module on the motherboard can convert it into a handheld portable signal. The signal used by the device; and the signal used by the handheld portable device can be converted into a USB signal by using the USB signal processing module, and then converted into a network signal by the network signal processing module and sent from the network cable to the cable through the RJ45 socket online. However, since the known communication interface converter has a network signal processing module for converting USB signals and network signals, the known communication interface converter will have a relatively large volume, making it easy to carry It is inconvenient to use. In particular, the signal needs to undergo multiple conversions by the USB signal processing module and the network signal processing module, which will affect its transmission efficiency.

In view of this, the present inventors aimed at the above-mentioned problems, conceived deeply, and actively researched and improved trial production to develop and design the present invention.
