Description

A network distribution frame based on POE power supply

technical field

The utility model relates to the technical field of low-voltage power supply equipment, in particular to a network distribution frame based on POE power supply.

Background technique

In recent years, with the rapid development of electronic communication equipment, the types and equipment of low-voltage electrical equipment continue to increase. Therefore, for different low-voltage electrical equipment, such as network power supply, it generally requires a 48V low-voltage DC power supply, so , POE technology came into being, with the rapid growth of network power supply demand. Now general-purpose network switches do not have a network power supply function, and POE network switches that can be powered are expensive. For users who already have a network switch but need network power supply, the cost of replacing the switch is too high. In view of this situation, people have developed a network distribution frame with power supply. For example, the Chinese patent number is: 201420569620.2, and the name of the invention is "POE power supply network distribution frame", which discloses a network distribution frame with power supply. However, through practice, it is found that the above-mentioned technical solution has the following technical defects: one, the quantity of output ports (eighteen) is difficult to meet the demand of power supply; two, the structure is complicated, and each RJ45 interface group needs a PCB board, Therefore, at least three PCB boards are required, which has the disadvantages of high failure rate and high cost.

Utility model content

The technical problem to be solved by the utility model is: according to the needs of network power supply, the network power supply needs to be realized on the premise that the user does not have a POE network switch, and a POE-based power supply that can provide 24 output ports at the same time is designed and developed for this purpose. network distribution frame.

The technical scheme that the utility model takes for solving the technical problem existing in the known technology is:

A network distribution frame based on POE power supply, the network distribution frame (2) includes a POE power supply (4), an RJ45 interface module, and a PCB board (5); the RJ45 interface module has twenty-four RJ45 interface; the output voltage of each RJ45 port is 48V; the PCB board (5) is electrically connected with each RJ45 interface; the positive pole of the POE power supply (4) is connected to the network distribution frame (2) through a cable The fourth pin and the fifth pin of the corresponding port are electrically connected; the negative pole of the POE power supply (4) is electrically connected to the seventh pin and the eighth pin of the corresponding port of the network distribution frame (2) through a cable.

Further: the POE power supply (4) is installed behind or above the port of the distribution frame.

The advantages and positive effects that the utility model has are:

By adopting the above technical scheme, the utility model adds a POE power supply to the network distribution frame of the traditional network cabinet, so that the traditional network distribution frame not only has the function of data exchange, but also has the function of providing power for network equipment; that is, the traditional The passive network distribution frame has become an active network distribution frame; at the same time, the RJ45 interface module in the utility model has twenty-four RJ45 interfaces, so it can output 24 signals at the same time to meet the needs of multiple interfaces.

Because the positive pole of the POE power supply described in the utility model is electrically connected to the fourth pin and the fifth pin of the corresponding port of the network distribution frame through the cable; the negative pole of the POE power supply is connected to the corresponding port of the network distribution frame through the cable The seventh pin and the eighth pin are electrically connected; therefore, it has the advantage of simple and convenient wiring; at the same time, it is found through experiments that the above connection method can well ensure that each RJ45 port outputs a stable 48V power supply, so the utility model is also It has the advantages of high stability and performance.

Because the utility model adopts a PCB board to transmit data for the RJ45 interface module, it has the advantages of low failure rate, simple structure and low cost.

Detailed ways

In order to further understand the utility model content, characteristics and effects of the present utility model, the following examples are given hereby, and detailed descriptions are as follows in conjunction with the accompanying drawings:

Please refer to Fig. 1 and Fig. 2, a kind of network distribution frame based on POE power supply, described network distribution frame 2 comprises a POE power supply 4, an RJ45 interface module, and a PCB board 5; Described RJ45 interface module has two Fourteen RJ45 interfaces; the output voltage of each RJ45 port is 48V; the PCB board 5 is electrically connected to each RJ45 interface; the positive pole of the POE power supply (4) is connected to the corresponding port of the network distribution frame 2 through a cable The fourth pin and the fifth pin of the POE power supply are electrically connected; the negative pole of the POE power supply 4 is electrically connected to the seventh pin and the eighth pin of the corresponding port of the network distribution frame 2 through a cable; when in use, the network wiring The frame 2 is installed inside the network cabinet 1;

Under normal circumstances, the twenty-four RJ45 interfaces of the network distribution frame have occupied the entire network distribution frame. Therefore, during the implementation process, there is no space for the POE power supply at the front end of the network distribution frame, so the preferred solution is to place the POE power supply 4 behind or above the port of the distribution frame; through many experiments, it is found that the above connection method can be very good The ground ensures that each RJ45 port outputs a stable 48V power supply.

The embodiments of the present utility model have been described in detail above, but the content described is only a preferred embodiment of the present utility model, and cannot be considered as limiting the implementation scope of the present utility model. All equal changes and improvements made according to the application scope of the utility model should still belong to the scope covered by the patent of the utility model.
