Memory expansion device and computer host

Abstract

The invention discloses a memory expansion device and a computer host. The memory expansion device comprises a mounting base used for being connected with the computer host, an embedding piece used for clamping the top end of a memory bank, an expansion groove used for detachably inserting the memory bank and fixed to the mounting base, an elastic assembly connected with the embedding piece and used for driving the embedding piece to slide up and down to fix the memory bank in the expansion groove, and a transverse fixing mechanism which is connected with the elastic assembly and is used for transversely fixing the memory bank while the memory bank is longitudinally and fixedly clamped in the expansion groove by the embedding piece. The embedded piece is loosened, so that the embedding piece is driven to drive the memory bank to be installed to move downwards to be installed in the expansion groove under the elastic action of the elastic assembly, meanwhile, the elastic assembly drivesthe transverse fixing mechanism to transversely fix the memory bank installed in the expansion groove, and the expanded memory bank is prevented from falling off from the expansion groove after beingsubjected to external force.

Description

technical field [0001] The invention relates to an installation field, in particular to a memory expansion device and a computer mainframe. Background technique [0002] Memory expansion, also known as extended physical memory, means that the motherboard has multiple memory sticks, which can be expanded by increasing the number of memory sticks. [0003] The memory stick, also called random access memory, is an internal memory that directly exchanges data with the central processing unit. It can be read and written at any time (except when refreshing), and it is fast, and is usually used as a temporary data storage medium for operating systems or other running programs. [0004] Most of the existing memory expansions manually insert the memory sticks to be expanded into the mainframe of the computer. When there is an external force to touch or the clamping is loose, it is easy to cause poor contact or even fall off, and the stability is not good. Contents of the invention...
