Problems solved by technology
This is mainly because on the one hand, the PCB layout density is getting higher and higher, and the power consumption is getting bigger and bigger. On the other hand, the transmission capacity of the PCB board is limited, which is mainly determined by the structure of the PCB board. The maximum thickness is 175 microns. Although it is possible to increase the current carrying capacity by increasing the number of layers of the PCB board, the current carrying capacity of the inner layer of the PCB is lower than that of the surface and bottom layers of the PCB board. On the other hand, how to ensure that the current flows between the layers of the PCB board? Uniform transmission between PCBs is also a difficult problem. At the same time, increasing the number of layers of the PCB board directly leads to an increase in the cost of the PCB board. Therefore, how to improve the current carrying capacity of a single PCB board without increasing the cost of the PCB board is a difficult problem.

The invention relates to the fields of power supplies and connectors, in particular to a server and large-current transmission of a single circuit board in the field of telecommunication. The invention provides a connector for large-current transmission based on the single circuit board, which comprises screw rods and screw caps, a through hole is arranged in a PCB, the screw cap is welded in the through hole, the screw rod is connected with the PCB through the screw cap, and contact faces of two faces of the PCB and the connector are provided with copper coating regions. The invention greatly increases the current-carrying capacity of the single PCB, and has current-carrying capacity far more than that of the PCB directly using the same layer quantity, the same materials and the same thickness.
Description
technical field [0001] The invention relates to the fields of power supply and connectors, especially the large current transmission of a single circuit board in the server and telecommunication fields. Background technique [0002] At present, in the field of electronic design, how to transmit large currents on PCB boards has become an important bottleneck restricting product power and reliability. This is mainly because on the one hand, the PCB layout density is getting higher and higher, and the power consumption is getting bigger and bigger. On the other hand, the transmission capacity of the PCB board is limited, which is mainly determined by the structure of the PCB board. The maximum thickness is 175 microns. Although it is possible to increase the current carrying capacity by increasing the number of layers of the PCB board, the current carrying capacity of the inner layer of the PCB is lower than that of the surface and bottom layers of the PCB board. On the other h...
