Abstract

The utility model relates to a general computer bus structure, composed of a special socket, a function template and a support. The general computer bus structure provides connection among a plurality of modules without motherboards; the general computer bus structure can be identical with a certain standard bus logically and adopts anther splicing specification of identical standard in physical structure; a traditional bus mother board and a frame are canceled. The utility model has the advantages of convenient and flexible use and standardization.

Description

General computer bus structure

The utility model relates to a kind of general calculation machine bus structure, belongs to computer.

The computer bus technology occupies an important position in computer system, from S-100 bus to STD industry control bus, the PC bus, though bus specification has nothing in common with each other, but all bus structure all have motherboard, and be mutually perpendicular between motherboard and the functional module, their connection is to be connected mutually with socket on the motherboard by the golden finger of board edge.This is to the design "smart" products, and is narrower in the locus, have requirement and product that work in vibration environment on the weight.As electro-mechanical system, smart instrumentation, mobile data acquisition system adopts the structure of band motherboard just to seem heavy, because of generally all having interior cabinet, makes it very inconvenient.For addressing this problem, what occur in a large number in this field usually is the self-designed nonstandard template of user, and interface thousand becomes ten thousand kinds, and no standardization can be talked, poor reliability, and lot of manpower and material resources has been wasted in the low-level duplication of labour.

The purpose of this utility model is to overcome weak point of the prior art and the computer bus structure that provides a kind of multimode of not having a motherboard to connect, this structure bus with a certain standard on logical definition is identical, it can be the S-100 bus standard, also PC bus standard; But on physical arrangement, adopted another kind of standard identical patch standard, cancelled traditional bus mother board and frame.

The purpose of this utility model is achieved in that the socket 2 that adopts a kind of special double pin formula, this double socket is that existing double contact pin and twin-string socket are combined into a product, many socket square holes 1 that can insert contact pin are arranged above it, be the gold-plated contact pin 3 that is connected with socket square hole 1 below, contact pin 3 passes functional template 4 and is welded on the functional template 4 of printed circuit, functional template 4 has just possessed the function of bus naturally, the contact pin 3 that passes template 4 inserts the socket square hole 1 on lower floor's one functional template 6 again, the contact pin that passes template 6 inserts the socket square hole on lower floor's functional template 7 again, the polylith template is down pegged graft so layer by layer, just as the essential performance of motherboard bus is arranged.

Accompanying drawing 1 is a shape assumption diagram of the present utility model.

Be described in detail content of the present utility model and embodiment below in conjunction with accompanying drawing 1:

Adopting a kind of special bus hub 2 can be biserial, also can be three row, pin number does not have strict restriction, in order to mate with existing connector, proposed standard can be 64 pin biserials, also can be 48 pin, three be listed as, 96 pin, three row, but needle gage is 2.54mm, the pin of contact pin 3 is long to be 13.0mm-15.0mm, the thick 0.75mm of pin, the template distance is the 15.24mm(0.6 inch) about.

When using the PC bus standard, bus hub 2 can be adopted 64 pin biserials, and the ordering of 62 core signal wires on socket 2 of the I/O passage of IBM-PC machine is the same with primary standard, and unnecessary pin can oneself be defined as other purposes.When the leg number of bus definition than the double edge connector of 64 pin for a long time, can select three row's pin edge connectoies of 96 pin for use.

The utility model has the advantages that: the riding position of double socket on template is not subjected to originally must be placed on the restriction of board edge, can be placed on the centre of template, and be more flexible. This technology can be fit to the transplanting of various bus standards, and it is unified that the physical arrangement of bus will be tending towards, and makes it standardization.

Claims (2)

1, a kind of general calculation machine bus structure, by socket 2, functional template 4 and support 5 constitute, it is characterized in that: socket 2 is double straight formulas, many socket square holes 1 are arranged above it, be the gold-plated contact pin 3 that is connected with socket square hole 1 below, contact pin 3 passes functional template 4 and is welded on the functional template 4 of printed circuit, functional template 4 just possesses the possibility of bus, the contact pin 3 that passes template 4 inserts the socket square hole 1 on lower floor's one functional template 6 again, the polylith template is down pegged graft so layer by layer, has just had the essential performance of motherboard bus, can be the S-100 bus standard on logical definition, also PC bus standard has been cancelled traditional bus mother board.

2, by the described bus structure of claim 1, it is characterized in that, bus hub 2 can be 64 pin biserials, also can be 48 pin, three be listed as, 96 pin, three row, needle gage is 2.54mm, the pin of contact pin 3 is long to be 13.0mm-15.0mm, and pin slightly is 0.75mm, and the template distance is the 15.24mm(0.6 inch) about.
