Expansion module, pcie expansion module, chassis assembly, computer, and server cluster

Abstract

An expansion module, a PCIE expansion module, a chassis assembly, a computer, and a server cluster are provided. The expansion module comprises: a bracket provided with a connecting arrangement, the bracket being detachably connected to a computer through the connecting arrangement; a first circuit board provided on the bracket and having an electrical connection structure for electrically connecting the computer and an electrical connection port for electrically connecting an external device, the first circuit board being electrically connected to the computer through a cable; wherein the first circuit board has two opposite ends, the electrical connection structure is led out from or located at the first end of the first circuit board, and the second end of the first circuit board is provided with the electrical connection port; an end portion of the bracket is provided with an end plate adapted to a mounting port, the end plate being provided with a first through hole; the electrical connection port extends through the first through hole such that the electrical connection port is exposed when the expansion module is connected to the computer. In the present application, an interface board may be omitted, which helps to improve the high-speed signal transmission quality of the expansion module.
