Problems solved by technology

The problem with this method is that the ability of a single pin of the connector to transmit current is limited. If the density is increased, the power layer (ground layer) on the PCB board will be destroyed, thereby overheating the entire PCB board, and the power connector will also be overheated and damaged. PCB board or connector, resulting in abnormal power supply of the system or even a fire
At the same time, parallel use requires more space, and the space of servers and telecom cabinets is very limited, and there is no space for so many power connectors

Embodiment Construction

[0024] Below in conjunction with accompanying drawing, the present invention will be further described.

[0025] see Figure 1 to Figure 3 :

[0026] The present invention provides a connector based on large current transmission between multiple circuit boards, the connector includes a metal plate 1, screws 2 and nuts 3, the metal plate 1 and the PCB board 4 are provided with a through hole 5, the metal plate 1 is installed on the PCB board 4 through screws 2 and nuts 3. The metal plates 1 form a group of two pieces, which are arranged on two PCB boards 4 respectively. The two metal plates 1 are connected flexibly or fixedly, and the two metal plates 1 are perpendicular or parallel to each other; The current conductor, the entire copper plate itself is a heat sink, which can assist the system to dissipate heat. A copper-plated area 6 is provided on the side of the PCB board 4 relative to the metal plate 1, and the copper-plated area 6 is provided with a gold-plated layer. T...

Abstract

The invention relates to the field of power supplies and connectors, in particular to a server and large-current transmission among circuit boards in the field of telecommunication. The invention provides a connector based on large-current transmission among multiple circuit boards, which comprises metal plates, screws and screw caps, wherein the metal plates and PCBs are provided with through holes, and the metal plates are arranged on the PCBs through the screws and the screw caps. Every two metal plates are formed into a group and are respectively arranged on the two PCBs, and the two metal plates are connected movably or fixedly, and are mutually vertical or parallel. The invention provides a server and a large-current connector which generates large current with low heat value and has better oxidization and corrosion resistance capacities for a long time in a telecommunication cabinet; and the invention is suitable the transmission of current between every two plates or between plates and wires.

Description

technical field [0001] The invention relates to the fields of power supplies and connectors, especially the transmission of large currents between circuit boards in the field of servers and telecommunications. Background technique [0002] In the field of servers and telecommunications, with the increase of chip power consumption, there is often the problem that multiple circuit boards share the same set of high-current power supplies, which requires suitable connectors to transmit power to each circuit board. Since the transmitted current is very large, and the space of the server and telecom cabinets is very small, it is impossible to use the cable routing method, and the current power connectors generally have too small flow to meet the design requirements. [0003] At present, for the transmission of large current between PCB boards, it is mostly solved by parallel application of multiple low-current connectors with small carrying capacity. This connection can be a crim...
