High-speed serial expansion interface

Abstract

The invention provides a high-speed serial expansion interface, and relates to the technical field of serial interfaces. The high-speed serial expansion interface comprises a main body, one side of the main body is fixedly connected with a serial interface, the outer side of the serial interface is provided with a protection assembly, the protection assembly comprises two protection covers, the two protection covers are arranged on the outer side of the serial interface in a sleeving mode and are oppositely arranged, the two sides of the two protection covers are fixedly connected with connecting pieces, one end of the connecting piece is fixedly connected with a moving block. According to the high-speed serial expansion interface, when the protective cover is separated, the serial interface is exposed, protection of the serial interface is facilitated, dust prevention treatment on the serial interface when the high-speed serial expansion interface is not used at ordinary times is avoided, meanwhile, when a rack moves to enable a one-way limiting clamping jaw to be connected with a torsional spring through a rotating rod, the rack is used for clamping, so that the connecting plate can be limited, the protection assembly is in an open state, and at the moment, the external connecting terminal is connected with the serial interface in an inserting manner.

Description

technical field [0001] The invention relates to an expansion interface, in particular to a high-speed serial expansion interface, belonging to the technical field of serial interfaces. Background technique [0002] In the context of today's rapid development of information technology, high-speed serial expansion interfaces are widely used to improve device functions, expand compatibility, integrate multiple devices, and be more intelligent, convenient, efficient and fully meet the requirements of modern social work and life. need. Many public interconnection standards today are based on serial transmission to achieve speed, physical compactness and link toughness, and are widely provided to users, such as notebook computer display interconnection, high-speed backplane interconnection and presented memory structure, etc. , for this reason, the research and development of the high-speed serial expansion interface has been favored by those skilled in the art all the time, but ...
