Group connection network route joint universal conversion device

The invention relates to a universal joint conversion structure, in particular to a network route with an RJ45 joint and combined with a power supply device, and then a special joint set and various types of standardized joints as output.

Today's technology popularizes 3C products. The so-called 3C products mean electronic products that are related to information, communication, and consumer electronics. These products have gradually become essential items for people's livelihood. Carry at least the same electronic products with you. Information-related electronic products are mainly used for information processing and computing, such as computers; communications-related uses are for the transmission of audio, information, video, etc., such as mobile phones, telephones, etc.; consumer electronic products are functional for living. Mainly, such as audio, TV, lamps, refrigerators, electric cookers, electric stoves, etc., need power supply products.

Most 3C electronic products require electricity to supply. The technology development of electronic products has become more diversified and multimedia demanded. Therefore, more and more 3C products are not differentiated from the above three categories, and they are no longer just a single function. It has been converted into the above-mentioned three types of "information", "communication" and "consumer electronics". At the same time, we attach importance to the interconnection of 3C products. Therefore, "connectors" are how to make each other connectable. Become a very important role.

There are quite a variety of types of joints on the market, including "standardization" and "specialization". "Specification" is a compatible joint structure to facilitate various products. The "specialization" is based on the brand to enable consumers to use only the various types of electronic products they produce, so the special connector is designed to be the electronic product user of the brand.

The type of "connector" can be divided into "male joint" and "female joint". The "female joint" is exposed at the joint, also known as the joint. The "female joint" is connected. The part is embedded, also known as the "Port". The connection of the joints can be divided into two categories: "Power Transmission" and "Signal Transmission". Among them, "Power Transmission" mainly provides electricity. The transmission of "signal transmission" is carried out by various signals, including audio signals, data signals and video signals.

For the specification and compatibility of the "signal transmission" connector type analysis, the connector used for the audio signal is commonly used in mobile phones, audio, computers, televisions, musical instruments, music players, etc., such as the domestic 100212904 The new type of patent disclosed in the "Audio Line Audio Connector Structure Improvement"; the connector used in the data signal is mostly used in computers, cameras, cameras, mobile phones, etc., mainly for the transmission of internal data, as disclosed in the domestic patent No. 099221339 "Connector socket"; the connector used for video signal is commonly used in televisions, video recorders, video cameras, computers, etc., such as the "signal connector structure" disclosed in the new patent No. 100215901, and the domestic 094213324 The "Video Junction Box" disclosed in the new patent.

Further analysis, the connection components are only a simple classification in the foregoing. In fact, even if the type of application is already a normalized component, the type is still quite complicated; for example, the connector for image transmission is also called "terminal". Image side The sub-categories can be divided into AV (analog signal terminal), S (analog signal terminal), color difference (analog signal terminal), DVI (digital signal terminal), HDMI (digital signal terminal with sound, according to the image quality and level). It is a bidirectional terminal that can be output and input).

The above are all single-function connectors, that is, only for a single type of signal transmission. However, in the current multimedia products, the signal transmission behavior is in one-time use of electronic files of audio, video, and data, so the signal transmission In order to transmit the multiple signals that can be included in the above three types, this method can be solved without a single transmission, so the industry is also developing towards a multi-functional connector device.

According to the connector structure of a plurality of signal transmission connectors, such as the "composite interface device" disclosed in the Japanese Patent No. 096117497, the device includes: at least one input terminal for receiving an indoor power And forming a information transmission; a power processing unit, the power processing unit is connected to the input end, the power processing unit is configured to convert the indoor power into a working power and then transmit; a signal processing unit, the signal processing unit The information is coupled and transmitted; and a plurality of output interfaces are used for outputting the city power and the working power, and connecting an electronic device to complete the information transmission.

For example, the connector structure of a plurality of signal transmission connectors is known, such as the "connector for connecting RJ-9 port and TRS port" disclosed in the Japanese Patent No. 095216652, which includes: at least one RJ-9 a port for connecting an RJ-9 device using at least one RJ-9 connector; and at least one TRS port for connecting a TRS device using at least one TRS connector; wherein at least one of the RJ- The 9 port is electrically coupled to at least one of the TRS ports.

There is also a connector structure with a variety of signal transmission connectors, such as domestic The "communication component of the local telephone system via the mobile computing device and its switching device" disclosed in the new patent No. 100210905 includes: a base housing having at least a constant hole; an audio input unit disposed at the machine The base housing is disposed corresponding to at least one of the through holes for receiving a dual tone multi-frequency audio; a first connection port is embedded on the frame housing for electrically connecting to a fixed network communication network route a second connection port embedded in the base of the base, electrically connected to the first connecting port, the second connecting port is electrically connected to an external analog phone; a hook/extract The circuit is disposed in the housing and electrically connected to the first port for generating an off-hook signal; and a hybrid circuit is disposed in the housing and electrically connected to the audio input unit and The on-hook/off-hook circuit is configured to output the dual-tone multi-frequency audio via the first port when the off-hook signal is generated.

In the above structure, the three cases are all connector structures of a plurality of signal transmission adapters, wherein the first case is provided with a complex array interface for the user to connect various types of electronic devices, and the interface includes a power output interface and an information transmission interface. Its function is to introduce the general city power and information signals into the input end, separate the power and the signal separately, and then connect to each output interface respectively, so that the user can use different output interfaces to connect various electronic devices. The second case is a structure in which the RJ-9 adapter and the TRS connector are interchanged. The RJ-9 (Registered Jack 9) is the most commonly used connection between the telephone and the handset. TRS (Tip Ring) Sleeve) connects to a stereo or voice device The most common connection specification is the junction; the third case provides the purpose of audio conversion, electrically connecting the first connection port of the adapter device to a fixed network communication network line, and selectively connecting the second connection of the adapter device机电 An external type of telephone is electrically connected to the telephone, and the user interface of the mobile computing device can display a telephone number in the stored address book and generate a dialing instruction corresponding to the telephone number.
