Structure of bus socket and expansion method thereof

Abstract

The invention provides an expansion structure of a bus socket and an expansion method thereof. the expansion structure comprises an expansion mainboard, wherein, a first plug body that can be connected with a computer mainboard is arranged at one side of the expansion mainboard, and a first socket body is arranged at the other side of the expansion mainboard; first left slot groups and first right slot groups connected in parallel are matched and arranged between the first socket body and the first plug body, at least four first left slots connected in parallel are arranged in every first left slot group, and at least four first right slots connected in parallel are arranged in every first right slot group; the first right slot group and the first left slot group are respectively connected with a primary shared device, and the primary shared devices are switched with a card reader after being connected in parallel; a first sub-control panel is matched and arranged on the expansion mainboard and is connected with a main control panel, and the main control panel is also connected with the computer mainboard. The expansion method of the bus socket include the steps as follows: preparation, the socketing and installation of the expansion mainboard, the socketing and installation of an expansion sub-board, the assembling and controlling of the primary shared devices, secondary shared devices and third-level shared devices, etc.

Description

technical field [0001] The invention relates to the technical field of computer bus sockets, in particular to a bus socket structure and an expansion method thereof. Background technique [0002] In recent years, ISA bus general-purpose computers have been eliminated, and the market is full of PCI bus general-purpose computers with better performance. However, there is still only one bus socket on the motherboard of PCI-bus general-purpose computers. In the field of special needs like invoicing, it is extremely annoying to put a large number of computers on one computer and one card, or to insert and unplug a dedicated card for one user. [0003] Such as the patent No. ZL01112805.4 Chinese invention patent "the ISA bus extension method of general PC peripheral service function" (announcement number is CN1318799C) is exactly this kind of design; A kind of ISA bus extension method of general PC peripheral service function, not Change the software and hardware in the ISA bus s...

AI Technical Summary

Problems solved by technology

This kind of design only considers the expansion method of the signal electric logic and adopts the cable connection, and it will fail on the PCI bus general-purpose computer with a clock frequency of 33M.

When the 33M pulse train travels on the line, the long line and decoupling issues become important factors for the success of the transmission, that is, the geometric size and spatial layout of the connecting line will seriously affect the correctness of the signal flow and electrical logic

Some merchants produce special cables with plug sockets, which can be used for computer bus connection. The existing technology is weak to expand the bus socket on a PCI bus general-purpose computer.
