Description
Technical field
The utility model relates to a kind of slot, and particularly relevant for a kind of expansible type slot that is positioned on the motherboard.
Background technology
Computer bus is gone through Industry Standard Architecture (the Industry Standard Architecture of the eighties, ISA) peripheral element connecting interface of framework, the nineties (Peripheral Component Interconnect, PCI) with AGP (Accelerated Graphics Port, AGP) framework.Yet for present great amount of data transmission, PCI and AGP have not applied and have used.Therefore the leading 3GIO (Third Generation I/O Architecture) of Intel company forms PCI-SIG (PCI SpecialInterest Group) in conjunction with many companies, and proposes PCI Express framework to replace prior art.
PCI Express continues to use configuration (configuration) space and the master data transmission rule of PCI, but the multiple spot that is different from PCI passes (multi-drop) parallel bussing technique down, PCI Express introduces switch type (switch) point-to-point (peer-to-peer) serial transmission technology, and the differential wave group (differential signal pairs) by passage (lane) by name is to transmit signal.One group of passage comprises transmission end (transmitter) and receiving terminal (receiver), and its transmitting bandwidth is 250MB/s under single worker's pattern.The specification of one group of passage is called PCI Express x1, and PCI Express can increase frequency range by increasing number of channels, for example specifications such as x1, x2, x4, x8, x16, x32.Possess 16 groups of passages with PCI Express x16, its single labour movement as the time frequency range of 4GB/s is arranged, nearly be the twice of the 2.1GB/s frequency range of AGP 8X.In addition, PCI Express also can move full-duplex mode, that is original only transmission end and the receiving terminal of one-way transmission can adopt transmitted in both directions, so in the PCI of full duplex Express x16 specification, its transmitting bandwidth can reach 8GB/s.In addition, the interface card of the specification of accord with PCI Express and slot can have two-way compatibility, also can be up or compatible downwards.Particularly, the interface card of four passages is compatible in the slot of eight passages, and the interface card of eight passages is also compatible in the slot of four passages.When the port number of slot and interface card not simultaneously, the number of channels of its actual transmissions is standard with junior.
Fig. 1 is the interface card of existing a kind of accord with PCI Express x16 specification and the schematic diagram of slot configuration on motherboard that belongs to PCI Expressx1 specification.Please refer to Fig. 1, the slot 100 of existing less passage is disposed on the motherboard 20, and forms breach to support the interface card 10 than multichannel at one tail end 112.Because interface card 10 unnecessary parts can be exposed to outside the slot 100, therefore make the plant instability of interface card 10.In addition, exposed pin 12 (signal terminal) is subjected to dust for a long time and hoodwinks, and easily causes the passivation of its conductivity or misconnection to touch other electronic components on the motherboard 20, and exerts an adverse impact.
