Embodiment 1

[0056] The power supply system provided by this embodiment can be used in communication equipment, such as Figure 1~4 As shown, it includes: power input unit 1, power confluence unit 2 and power distribution unit 3;

[0057] Wherein, the power input unit 1 can adopt a multilayer PCB (printed circuit board), and is installed above or below the backplane 4 of the system; the power outside the system is input in the power input unit 1 through the power supply board 5, and the power input unit 1 The power input interface 11 (which can be a cable interface or a power connector) can be directly connected to the external power supply board 5 or connected to the external power supply board 5 through a cable. Generally, the power input unit 1 is installed on the back of the system. When it is above the board 4, it can be directly connected to the external power supply board 5, and when the power input unit 1 is installed below the backplane 4, it can be connected to the external power...

Embodiment 2

[0064] The power supply system provided by this embodiment can be used in communication equipment, such as Figure 5-6 As shown, the power supply system is basically the same structure as the power supply system given in the first embodiment above, and also includes several parts: a power distribution unit, a power confluence unit and a power input unit; the difference from the first embodiment is that the power supply system includes : at least two power converging units and at least two power distribution units; the power supply system of this structure can be used in the backplane of double-sided boards, such as Figure 5 , 6 As shown, two power distribution units are respectively placed on the front and rear sides of the backplane, and the two power distribution units are respectively electrically connected to the power input unit through two power converging units.

[0065] The above power supply system can be flexibly configured with different numbers of power distribut...

Embodiment 3

[0068] Such as Figure 7 , 8 As shown, this embodiment provides a power supply system that can be used for communication equipment, which is basically the same as the power supply system given in the first embodiment above, the difference is that the power distribution unit and the backplane of the power supply system are integrated, that is, on the back A dedicated power supply area is set in the board as a power distribution unit, and all power distribution units are set on the backplane. The power supply system with this structure can simplify assembly and reduce the complexity of assembly because the power distribution unit is integrated with the backplane of the system (share the PCB of the backplane).

Abstract

The invention discloses a power supply system and method as well as communication equipment and belongs to the field of electronic technology application. The power supply system comprises a power supply input unit, a power supply distribution unit and a power supply confluence unit, wherein the power supply input unit is provided with a power supply input interface and a power supply output interface, the power supply input interface is electrically connected with an external power supply and is used for introducing the external power supply, and the power supply output interface is electrically connected with the power supply confluence unit; the power supply confluence unit is connected between the power supply input unit and the power supply distraction unit; the power supply distribution unit is provided with an input power supply interface and an output power supply connector; and the input power supply interface is electrically connected with the power supply confluence unit, and an output power supply connector is used for connecting a single board. All the parts of the power supply system are mutually independent, can be conveniently assembled on a back plate and can be easily and independently replaced after being damaged, thus the problems that power supply by a confluence copper plate is difficult to be applied to a double-faced back plate, is more complicated in assembling and poor in safety and heat dissipation.

Description

technical field [0001] The invention relates to the application field of electronic technology, in particular to a power supply system, method and communication equipment that can be used in communication products. Background technique [0002] Development of communication product system: In modern electronic communication products, the backplane is usually used to connect electrical signal single boards, etc., that is, the backplane needs to provide signal transmission channels, and at the same time carry current to supply other boards. However, with the rapid development of the communication industry, the system capacity continues to increase, and the system energy consumption continues to increase, resulting in a sharp increase in the size of the backplane: the length is increasing, the number of layers is increasing, and the thickness is increasing. These bring great difficulty to the manufacture of the backplane, and the price is high. Because the signal rate is high, ...
